Ok, well, this is one of my favorite parts of the book. I really like this chapter and I think really important things are going on in it, so I’m going to try and explain the source of my enthusiasm about it. So one thing that’s potentially a little puzzling right at the beginning of the chapter is that Hegel talks indifferently and almost interchangeably about universality, negation, and mediation. So he says things like in 112, the second paragraph, “The wealth of sense knowledge belongs to perception, not to immediate certainty, for which it was only the source of instances. For only perception contains negation. That is, difference or manifoldness within its own essence.” And he talks about it in 115, about sensuous universality or the immediate unity of being and the negative. And then again says “the universal is in its simplicity a mediated universal.” Now I talked a little bit beforehand about the relation between determinate negation and mediation, where I take mediation to be a matter of inference, material/consequential relations, determinate negation to be a relation of material incompatibility, Aristotelian contrariety, which will be a big topic here, and in particular I indicated that I take negation to be the more fundamental notion, in part because, though I can’t catch Hegel saying this, it’s possible to define inferential relations in terms of relations of determinate negation. That is, we can say that ‘Pedro is a mammal’ follows from ‘Pedro is a donkey’, because and in the sense that everything incompatible with Pedro being a mammal is incompatible with him being a donkey. That’s a way of going from a notion of material incompatibility to a notion of inference. P implies Q just in case everything incompatible with Q is incompatible with P. So if we give Hegel a notion of determinate negation as a sort of metaphysical primitive, he’s going to get a notion of mediation out of it. But what about universality? One of the big points of this chapter is to argue that coming out of sense-certainty with an acknowledgement that determinate contentfulness requires universals, some kind of generality, in particular sense universals, observable properties, ones that can be applied immediately in the sense of immediacy of origin, that the application of these universals was not the result of a process of inference, but a matter of observation, perception, responsiveness in that way. One of the points of the chapter is to argue that in finding that the presence or activity of sense universals is implicit in the idea of sensory episodes that have some kind of determinate content we actually already have conceded a structure of negation that universality implicitly involves a rich metaphysical fine structure of negation. I’m going to argue that there’s two fundamental kinds of differences that Hegel sees as necessary for having any kind of universality in play, having any notion of, well any notion of universality in play, and he’s going to walk us through how we can elaborate five other senses of difference or negation out of those fundamental two. A different way of describing this same progression, a way that will turn out to be equivalent, is that in the sense-certainty section, the contents we were talking about, not themselves thought of as linguistic contents, but when we, as we have no choice, use language to try and specify these contents, we use what’s Strawson in his book Individuals called a feature-placing language. So feature-placing, when we say ‘It’s raining’ or ‘It’s fine’, because the language has a subjectpredicate structure, the surface structure of sentences like that is also subject-predicate, but you can see that’s just the surface structure. The ‘it’ in ‘It’s raining’ or ‘It’s fine’ is not referring to something. There’s not an object of which we’re predicating this universal. Rather it’s just a feature. We’re saying ‘There is rain’, ‘There is sun’, ‘It’s sunny’, something like that. And we say it exactly the same in German, ‘Es regnet’, and Strawson’s idea is that this is the most primitive sort of contentfulness. In feature-placing you just characterize it. You’re just placing this feature. And Strawson, in Individuals, engaged in a self-describedly Kantian exercise in what he calls reconstructive metaphysics, by contrast to descriptive metaphysics. He’s interested in how you could move beyond feature-placing content to a subject and predicate, individual and property structure, where you’ve still got the kind of universality you’ve got in feature-placing, those are repeatables, contentful repeatables—to say it’s raining is different than to say it’s fine or it’s sunny. Those are different. But now you add individuals, or particulars, or objects into the picture and Strawson was concerned—well, what’s required to get those in the picture and started thinking, well, this was his Kantian argument, you’re going to need something like space and time to locate them in and you’re going to need the capacity to track those objects, to follow them as they move through space. And this is a line that his student and the young John McDowell’s best friend, Gareth Evans elaborated in his work, saying really there’s two notions of space. He’s elaborating what Strawson made of Kant in the Transcendental Aesthetic, Evans collaborating with Strawson made of Kant, says it’s really two kind of space you’ve got to keep track of: ego-centric space, located around you—how are things relative to you—and public space, the public space that things move in. And you’ve got to be able to separate the effects of movement, in particular of your movement, that is the relative change between egocentric space and public space, in order to so much as have the idea of independent objects moving around in public space. You’ve got to know the difference between what happens when you turn your head and what happens when an object moves in public space, even though both of them involve shifts in how things are relative— in egocentric space, for instance. and Evans is fascinated that this is a sub-conceptual capacity at least in the sense that if your dog can catch a Frisbee, he’s got to have these fundamental capacities of tracking objects, of mapping egocentric space onto public space, that Evan’s Strawson’s Kant see as fundamental, but sub-conceptual capacities. So, all right, that’s a little of what Sellars called being around in the neighborhood, neighboring bushes around the Strawsonian idea of feature-placing language. So Strawson in Individuals sets himself the task of trying to see what sort of practical capacities knowers and agents would have to have to move from feature-placing consciousness to subject and predicate consciousness, to consciousness of individuals as the subjects of properties, where now we could say ‘This stone is warm and this stone is cold’. We move beyond the featureplacing, just ‘It’s sunny’ or ‘It’s rainy’. And what Hegel is going to argue in the “Perception” chapter is that everything you need to make that transition is already implicit in the feature-placing language, the feature-placing contents, if you just realize that there’s two ways in which the features can differ. They can either be merely different in the way in which night— ‘It’s night’ and ‘It’s raining’ are different. Or they can be exclusively different, in the way in which ‘It’s night’ and ‘It’s day’ are different, or ‘It’s raining’ and ‘It’s sunny’ are different. He’s going to argue first that to see even the feature-placing things that we inherit from sensecertainty as determinately contentful, we’ve got to distinguish those two kinds of difference. And then in I just think a tour de force of an argument, he argues give him that difference between two kinds of differences and he’ll show how to build the full structure of objects and properties, particulars and universals out of it. I’m going to just for purposes of short-hand call that structure that’s beyond feature-placing, instead of calling a subject/predicate structure, I’m just going to call it the Aristotelian categorial structure and I’ll say why I think that should be pinned on Aristotle later in the development. So Hegel’s got to show us that there’s a complex fine-structure to the notion of universality even as it applies in feature-placing that is articulated by negation. So universality involves negation. In the metaphysics that will explicitly be pursued in the science of logic, in this book, determinate negation is a basic notion in terms of which we’re going to understand mediation, that is inferential relations, and it’s the basic notion in terms of which we’re going to understand universality. So although we can keep separate books on these notions, they’re intimately related and this is the fundamental term. Now I think maybe the easiest way into Hegel’s thought here is to think about the dawn of logic in Aristotle, the dawn of the notion of formal logic. And this is something I know very little about. My understanding of the history of philosophy basically starts with Descartes. I mean, I’ve read these guys, I have views about them, but I don’t have the kind of control of them that will let me, put me in a position really to stand behind things I say about guys any deader than Descartes. But you know people who do and, in particular James Allen is one of the world’s authorities on the origins of logic in Aristotle and downhill from there, so if you’re interested in pursuing this, you can do so responsibly. Just don’t ask me. But let me say parenthetically, when I was a graduate student, Gil Harman was notorious among the graduate students as the most unhistorical philosopher it was possible to be. And this was on the basis of things like his advice that it was a complete waste of time to read any philosophy written more than five years ago, because if whatever was in the older stuff was important it would have been talked about in the last five years and you should start with where the discussion is now, not where it was back then. And it was only some years later that I realized this was a slander on him and that in fact everything Harman did was rooted in his sense of the history of philosophy and grew out of his reading of the history of philosophy. It was just that he believed it began with Quine. Anyway, my sense is only driven slightly farther back to Descartes as well I’m confessing a shameful truth. Ok, but Aristotle, who room has it, started off with a distinction between two kinds of difference, between contraries and contradictories. So contraries are things like square and circular, universals that cannot apply to the same thing at the same time. Contradictories, like square and not square, also cannot apply to the same thing at the same time, but each property only has one contradictory, but it can have many contraries. So with red you only get not-red as the contradictory, but it’s got all the other colors as contraries, red, green, and so on. And Aristotle bequeathed us the square of opposition, relating contradictories, contraries, by negation and so on. You’ve seen all this in baby logic courses. Some of you are probably teaching—well, we probably don’t teach it, but at any rate you’re generally familiar with this. There’s two main strategies that one could have for thinking about this difference between contraries and contradictories. The tradition we grew up in, the tradition of modern mathematical logic that starts with Frege, as codified by Russell and in particular on down to Tarski, so I’m going to call this the Tarskian order of explanation, doesn’t start with the notion of properties. It starts with the notion of objects and begins it’s thinking about logic with merely different objects, a domain of objects about which all we know is which ones are the same and which ones are different. They’re merely numerically different. It’s a domain of objects. And identifies properties, to begin with, just with sets of objects. Red is its extension, a set of red objects. Square is the set of square objects. And low and behold, our domain might have something that’s both red and square. It’s in the intersection of those properties. Given that notion, we can define a contradictory property. The contradictory property not-red is the property that’s exhibited by all and only the objects that aren’t red. (Writing on the board.) So we’ve got our domain with all of its merely different objects, you can think of them as points, because points are all just alike except you can count them. We’ve got this domain and we have a property of being red, it’s just the set of those, and not-red is the set of everything that isn’t in there. And now we can say that something, say blue, is a contrary of red in case it implies not-red. So we’re going to define contrariety from contradictoriness. We use the notion of the complementary set of merely different objects to get a notion of formal negation, which lets us define the contradictory property not red. And then we can say, well look blue over here, every object that’s in that set is in the not-red set so it’s a contrary, whereas square here—it doesn’t follow from being square that something is not-red. This one is square, but it’s red, so square is not a contrary property to red. We’re building up a notion of contrariety starting with merely distinct objects introducing a notion of formal negation to introduce the notion of a contradictory and then treating contraries of a property P, Q counts as a contrary of property P just in case Q implies not-P. That’s the way Tarskian model theory does things. Let me say some more in the vicinity here. So Tarskian model theory has as the points of evaluation, relational structures. And a relational structure is just a domain, and we’ll just worry about the properties for now, a set of sets on it, which are understood as the extensions of properties. Formal negation is defined—unlike any ordinary property—is defined by a function or a constraint on interpretation that applies to all the points of the evaluation, all the relational structures. It says no matter which relational structure you look at, no matter which domain and which set of sets on that domain you look at, to be the contradictory of the property associated with any one of these is to be the set that is the complement of that set in the domain. So negation is a kind of function. From a point of evaluation, a relational structure, a predicate, it gives you a way of constructing another predicate, which is its contradictory. And that works no matter what point of evaluation you have. If you want to follow a contrary, if you want to follow blue from one point of evaluation, from one relational structure to another, you’re not automatically told how to do that. You’re what a contrary, let’s say you can follow red as having a different domain in this relational structure than it has in this one, and the rule for contradictory tells you how to compute the extension of its contradictory property not-red, and then it will tell you what it is for some other extension in there to be the extension of a contrary property, namely to be one that implies not-red, but it won’t tell you how to sort of follow the contraries from one world to another. This structure—I think of it as a bottom up structure, starting with the merely different objects, going through formal negation to define contradictories, and then from there to contraries—this is the one on which the Kripke/Lewis/Stalknaker possible worlds semantics is then built. Possible worlds semantics differs from Tarskian model theory in a couple of essential ways. One of them is that the points of evaluation are not thought of as relational structures anymore, but as possible worlds. Now for a long time, people didn’t think that difference was a big difference. And you’ll see a lot of fairly recent literature that ignores the distinction between possible worlds and models. One impassioned plea for keeping them separate is John Etchemendy’s book The Concept of Logical Consequence, which argues that we don’t understand logical consequence precisely because we’ve run together some model theoretic considerations and some possible worlds considerations. Roughly, thinking of logical consequence on the one hand as consequence in all models and on the other hand as consequence such that it’s impossible that the premises be true and the conclusion not true. And he sees systematic argumentative slides between those two, he argues, quite separate conceptions, where they come apart, you know, we don’t know what to say. But his is not the only such plea. I would say the fundamental difference between thinking in terms of relational structures, as you do in Tarskian model theory, and thinking about possible worlds, as you do in the possible worlds semantic framework, is that by definition relational structures come with domains. You know what all the objects in the relational structure are— they’re domain elements. On almost everybody’s conception of possible worlds, the actual world is a possible world. But what’s its domain? I mean, you can by brute force say, “Well, it’s a relational structure. God told me that I guess. So there must be domain elements so that everything else is a matter of sets of those.” So David Lewis transcendentally deduces the existence of fundamental particles and says what’s in his possible worlds is those fundamental particles and all their mereological sums. Right, mereology is a less-commitive sort of set theory. But possible worlds as initially conceived, they don’t come with domains. You can’t count everything in a possible world. There’d be no definite totality of things in them. Now, this is a bit of an excursus, but I think it’s worth it and if this is all old hat to you, think about something interesting while I’m telling this story. So the modal revolution really came in three waves. The first was Kripke’s furnishing of a complete semantics for all of the C. I. Lewis axiomatic systems of modal logic by treating necessity- by introducing an accessibility operator between possible worlds, treating necessity as truth in all accessible worlds, and possibility as truth in some possible world, and then pointing out that if you varied the algebraic properties of the accessibility relation you could get the different C. I. Lewis systems. You’d get S4 if you treat the accessibility relation as transitive. You would get S5 if you treated it as reflexive, transitive, and reflexive and so on. So he gave us a semantics for these modal logical systems that had been studied axiomatically since 1912, when C. I. Lewis came up with them. Parenthetically, Kripke was 14 when he did this, sent the proof in to Acta Philosophica Fennica, a finished journal, which they say good thing about the internet is no one knows you’re a dog, you know nobody knew he was a 14 year-old kid when he sent this thing in, they just knew he had a proof, a bunch of proofs. So Kripke showed how to use possible worlds to give a complete semantics for modal logic, indeed for every modal logic anybody really knew anything about at the time, though we’ve found ones that you need something else for since. So but all that was doing was interpreting modal operators in this framework, didn’t have anything to say about the meanings of non-logical expressions. In the second wave, and here there’s a lot of people one could mention, but David Lewis, Bob Stalnaker, and, until his young life was cut short, Richard Montague used this framework to extend Kripke’s results to give a semantics for non-logical expressions. And they said, well, we could understand a property like red as semantically corresponding to a function from possible worlds to sets of objects. So in each world there’s the set of red things. That’s the extension of red in that world. But the property is the function that assigns to each world the set of red things in it. It’s an intension, a function from points of evaluation, possible worlds, to extensions. David Lewis, in his classic article “General Semantics” showed how this gave us a recipe for assigning semantic interpretants with a power and precision that had hitherto been undreamed of. (Writing on the board.) So in the possible worlds version of it, here we’ve got terms that are assigned to objects at points of evaluation, because they’re extensions, and functions from points of evaluation to extensions as their intension. So the term’ Barack Obama’ is assigned to as its extension in this world Barack Obama and as it’s intension a function that in each world picks out the individual who is Barack Obama if he exists in that world. Syntactically you can think of a one-place predicate like walks as something that if you give it a singular term will give you back a sentence. So if you give the predicate ‘walks’ ‘Barack Obama’ as its input it’ll give you ‘Barack Obama walks’, a sentence as its <word obscured by coughing>. And what these guys’ brilliant idea was how semantically what you should assign as the interpretant of a one-place predicate is a function from the semantic interpretant of singular terms to the interpretant of sentences. So a sentence is interpreted as the set of possible worlds in which it’s true. And the term is assign a function from possible worlds to objects. So ‘walks’ is going to be a function from functions from possible worlds to objects to sets of possible worlds. (Still writing on the board.) Now we also have operators that take one-place predicates and turn them into one-place predicates. Those are adverbs like ‘slowly’ that turns ‘walks’ into ‘walks slowly.’ And what Lewis saw is this general apparatus gives us a way to assign the right kind of semantic interpretant to this. If we’re going to— I’ll just assume that we can follow objects from world to world and so say this is interpreted by a function from objects to sets of possible worlds, namely from the object to the set of possible worlds in which it has the property. Then to an adverb like ‘slowly’ we have to assign a function from functions from objects to sets of possible worlds to functions from objects to sets of possible worlds. The function from objects to sets of possible worlds that assigns an object to a set of worlds in which it walks to the ones in which it assigns it the set of objects in which it walks slowly. And now if you notice that semantically adverbs come in two flavors, attributive and non-attributive adverbs. So if I buttered the toast slowly, I buttered the toast. If I buttered the toast in the kitchen, I buttered the toast. But if I buttered the toast in my imagination, it doesn’t follow that I buttered the toast. So some of these transformations take you to properties such that it follows from the application of this that you still have this property, and other ones it doesn’t. Well, now, when you semantically interpret this adverb as a function from objects to sets of possible worlds to objects to sets of possible worlds—to functions from sets of possible worlds, now you can actually represent this inferential semantic difference between attributive and non-attributive adverbs. And no one had ever been able to do semantics with that kind of power and precision before the late ‘60s when apparatus came up. And Lewis called his article “General Semantics” because he said, you know it doesn’t depend on what you take the semantic interpretants of these things to be. This apparatus is general, or better neutral, between those. If you’re Michael Dummett, you think you should semantically interpret singular terms not by objects but by sets of recognition conditions for objects, the conditions under which he could recognize the ‘lark’ set. And he thinks that you shouldn’t semantically interpret sentences by sets of possible worlds or by truth-conditions, but by assertability conditions. Ok, that’s a philosophical disagreement, but this apparatus doesn’t care about that difference, it says well then a Dummanian (?) adverb is going to semantically interpreted by a function from functions from recognition conditions to assertability conditions to functions recognition conditions to assertability conditions. So in “General Semantics”, Lewis gives us a way of getting the power of this new intensional semantics no matter what we semantically associate with these different kind of expressions. And that’s really when modern formal semantics took off. Ok, Hegel doesn’t note that. <Laughter> This happens— well, you’d be surprised, but he does, but not that. But this second wave of the modal revolution was moving beyond Kripke’s semantics for modal logical opperators to a semantics for any non-logical expressions and that was a huge advance. The third wave of the modal revolution was initiated by “Naming and Necessity” and taught us about a priority, necessity, and, this newfangled thing, metaphysical necessity in a sense that we had never had before. My personal view is that was a bridge too far and we should have stayed with the second wave, but that’s prejudice. Ok, so what does all this have to do with Hegel? One way of thinking about the relation between contraries and contradictories starts with merely different objects, understands properties as sets of those merely different objects, so the properties are different if the objects that they’re sets of are different—that’s how you individuate sets, just by what’s in them—then defines formal negation by a complementary operation, so the contradictory of a property P, say red, is the property that’s exhibited by all and only the objects that don’t exhibit red. And then you can define contraries as something is a contrary, some property Q is a contrary of P if exhibiting Q implies exhibiting non-P. So that’s all Tarski, made particularly precise and explicit in Tarskian model theory, we build on top of that a possible worlds semantics and now what we do in the possible worlds semantics is look at functions from points of evaluation to extensions which is how we define negation. Negation is the same in all models. It means the same thing. You compute the contradictory of a property the same way in all models. Well, you compute the meaning of the adverb or the extension of the adverb the same in all models. Really, what the second wave of the modal revolution was doing is extending the treatment that Tarski had given to purely logical expressions to non-logical expressions. And now you could say something like well there’s no world in which something is at the same time both red all over and blue all over. That’s something you can say now in a way that in Tarskian model theory all you could do is restrict the set of models in some completely arbitrary way, whereas now we say oh, that’s part of the meaning of red and blue is that you track them across the worlds in such a way that nothing ever had both of those whereas red and square are not like that So this is a very powerful notion and you get a perfectly reasonable interpretation of contrariety at the end of the day when you built up in this way. What Hegel has is a completely different way of thinking about this relationship. He says start with the notion of contrary properties. That’s the notion of determinate negation. Blue is a contrary of red. They stand in the relation of determinate negation. Why is it determinate? Well, because it’s different from the way green stands to red. They’re both contraries. Abstractly they have that in common, but they’re determinately different. There’s more than one of them and you can pick out one of the contraries—blue by contradistinction from green, so you can treat something as— Ok so if you start with this notion of determinate negation which is a relation of Aristotelian contrariety, where any property can have many contraries though it has only one contradictory—remember we started with the notion of objects, built up contradictories, and eventually got to contraries in the Tarskian and the Kripke/Lewis/Stalnaker (KLS) extension of the Tarskian model theoretic apparatus—Hegel’s going to say well, what is formal negation, not-red? That’s what’s implied by every contrary of red. So if something is blue, it follows that it’s not red. If it’s green, it follows that it’s not red. The contradictory for Hegel is the minimum contrary, minimum in the sense that it’s the one that’s implied by all the contraries. Furthermore, we can understand that implication in terms of contrariety. Remember I said you can define P implying Q if everything incompatible with Q is incompatible with P. So in terms of that notion of material incompatibility we define contradictoriness. We’re doing this still at the level of properties. But this is turning the Tarskian scheme on its head. We’re going from contrariety to contradictoriness instead of the other way around. And from Hegel’s point of view, the notion of formal negation has thrown away all the content, all the determinateness, because you’ve thrown away everything that all the contraries don’t have in common. What all the contraries have in common is just being not-red and, from that point of view, you can’t see the determinate differences between them, the difference between green and blue and yellow and so on. So he’s going to say formal negation is the poorest emptiest kind of negation. But furthermore, what he’s going to go on to do next is build up the rest of the Aristotelian object-property structure, which the Tarskian and KLS approach has a good story about, but he’s going to have a completely different order of explanation. And that’s the story that we get in “Perception”. I haven’t said how that story goes yet. But let me stop there for comments or questions so far. So I’m saying that the way in is to think of the Aristotelian distinction between negation in the sense of contraries, determinate negation, and negation in the sense of formal negation, contradictoriness and see there’s two orders of explanation one could pursue. Aristotle doesn’t pursue either one of them. He just treats these as two different things and looks at what we can do with both of them, but the Tarskian order of explanation treats contradictoriness as prior, explains it in terms of mere difference of domain objects, and the Hegelian one is going to take determinate negation to be its primitive, semantically, logically, ontologically, and metaphysically. It’s going to take that to be the primary notion. And just as we saw you can get mediation out of that, you can get implication relations, so we can see you can get a notion of formal negation. The contradictory is the minimum contrary in the sense of the one that’s implied by all the contraries. Jack: So we talked a couple weeks ago about how— Well, I asked about the argument for why we should think that you can reduce content or mediation to determinate negation rather than just— clearly you have to acknowledge that they necessitate each other but why we have to take that further step of saying that it just consists of determinate negation. So I’m wondering if this is what you take to be the argument and it’s something like an inference to the best explanation, you know. Look at how much I can get out of starting with just one primitive. Bob: I mean, he’s going to have a lot more things to say about negation as the metaphysical essence of everything that there is—of thought and of being as well. But I think at the end of the day is give me this and look how much I can build out of this one primitive. He’ll offer other arguments, but you have to start somewhere and I think the things he needs to appeal to for those arguments are all more controversial than the fact of this constructability that he’s going to do. So I think the way of thinking of it is sort of implicit in the way I’ve presented it here—well, we’ve got one familiar way of thinking about things, incorporated in the Tarskian picture, get stereoscopic vision by thinking the same material through, taking another path through it, and compare and contrast. Student 1: Another question back from the dead. How does that tricky concept of sublation fit into this? And I might ask to look at paragraph 113 more closely to figure that out. Bob: Yeah, so far not at all. I mean, it’s going to be involved in— I mean, I will get to 113 and when we can talk about it, but when I said Hegel’s going to argue that the whole Aristotelian structure of objects and properties is implicit already in acknowledging a kind of generality even at the feature-placing level that acknowledges that the universal, that universal, that kind of generality is determinate in a sense that distinguishes these two kinds of difference, what he calls mere or indifferent difference, like red and square are different in that sense, and exclusive difference, that’s the determinate negation. Give him that, everything else is implicit in that. That’s going to be an aufhebung, translated or labelled as sublation in the translation. So ok. Let me say how this goes. Well, here’s a bit of commentary before I do this. Michael Friedman, building on work by Jaakko Hintikka, has given us an astonishing revelation about Kant, that essential features of the first critique come out of the years that Kant spent meditating on the proof structure of Euclid’s elements in which he realized that there were a number of conceptual arguments in Euclid’s Elements, arguments that could be reconstructed in a syllogistic way or as we could put it, you know the syllogism seems outdated, that you could represent with Venn diagrams inclusions and exclusions of concepts, but there was a class of arguments that couldn’t be represented that way. These are, not by coincidences—well, these are arguments like the argument that for any line segment there is a midpoint to it, which if you think about Euclid, he says take some circles that have the end points as centers and they’ll intersect in exactly two places—we’ve already proved that, Euclid says—and construct the line. That line will be, we will show, perpendicular, but it will also, we’re going to show, bisect the segment. You can always perform these constructions, so there always is a midpoint of two lines. That’s not an argument that you can reconstruct in syllogistic terms. It’s not an argument that you can represent in terms of Venn diagrams. Kant says, well it’s a matter of construction, rather than extracting conceptual inference or consequences. You’re constructing the midpoint. And that’s the way of course that infinite totalities come into geometry, because if every— if we can perform this construction on every segment, we can bisect it, then we can bisect the half and we can bisect that, and we can, by this construction, determine an infinite totality. So these notions of arguments of infinity and by construction, those are not conceptual arguments. You don’t get them by logic. You get them some other way. And Kant’s name for how you get them is synthesis. Synthesis, some of it’s conceptual and some of it’s not. Some of it’s intuitive synthesis. Now what— so, people had known that it was specifically by looking at argument in Euclid’s elements that Kant had come to think of the intellect as having this non-conceptual, constructive element, which was the only grip we have on infinity. You have to construct these things synthetically in intuition. It’s not a matter of the concepts. What Hintikka realized is that these are exactly the arguments that involve iterated, alternating quantifiers. For all..., there exists.... For every line segment there is a center point. That’s what you can’t represent in a Venn diagram, a relation between two sets such that for every point in this one there is a point in this one such that.... That the Venn diagram isn’t set for. Traditional logic couldn’t handle that. We needed to introduce, Frege needed to introduce quantifiers in order to get arguments that involved these alternating quantifiers, but particularly the for all...there exists... So this is why traditional logic couldn’t handle instances like ‘If someone admires everyone, then someone admires himself’, to see that that was a good inference. Ok, so look, Kant realized that the expressive power of traditional logic didn’t extend to exactly the things that we would add the expressive power to represent with quantificational logic. So he put something else in there—synthesis. Now what Friedman realized is that what Kant was doing is exactly like an alternate form of quantificational reasoning, one that uses Skolem functions, due to the logician Skolem. (Writing on the board.) And what he realized is that these tough inferences that involve alternating quantifiers <coughing and turning pages obscures words> two universals or two existentials becomes collapsible into one and just have an ordinary pair of stuff. It’s these alternating ones where new stuff happens. Instead of saying that, you could just have a function which goes from one of these and gives you this one. This says “for every f, there is a g”, but if you had a function such that if you gave it an f, it would give you a g as the consequence, you could do everything that you can do with these alternating quantifiers, you could do that with Skolem functions instead. And furthermore, the Skolem functions do it by—what?—by constructing this one. They determine the particular. This just says there is one, but the Skolem function actually gives you one. It’s a way of constructing them. And what Friedman realizes in the second chapter of his book on Kant and the exact sciences is Skolem functions are exactly what Kant’s intuitive syntheses do. It’s the same conceptual apparatus. He not only saw in Euclid’s elements that there was a class of arguments that couldn’t be represented in traditional logic, he came up with a construction in intuition method that basically was Skolem functions which are expressively as powerful as our quantificational apparatus. If I’d had an idea like that about Kant I would die and go to heaven. That would be it. I think the scales fall from our eyes when we see this, but what I want to say is in the wake of this Friedman and Hintikka sequential discovery and sort reconstrual of what’s going on we see that the twenty years that Kant spent thinking about the proof structure of Euclid’s elements yielded this incredible result. Well, that’s the same way Hegel concentrated on Aristotle on contraries and contradictories. And I think what he came up with from that is no less remarkable than what Kant came up with, which it’s taken us two hundred years to see exactly what it was, but you know that’s the way it goes when you make these big moves. And I think something of that order of magnitude came out of Hegel’s meditations on Aristotle here, specifically on contraries and contradictories. So, I don’t know, I’ll stop there. This is again a bit of a byway, but yeah. Anyway I recommend the Friedman chapter. Ok. Here’s the way I think Hegel’s story goes and I’d like us to get sort of clear on how that works as I’m telling the story and then we’ll go read some of the passages and try and catch him saying these things. So how is it that this whole Aristotelian structure of objects characterized by properties, and I still haven’t justified calling it that yet, is implicit in the difference between these two kinds of differences, or the difference between these two kinds of negation? Well, we start off with the idea that what makes a property the determinate property that it is the relations of exclusive difference that it stands in to other ones, that a property is the determinate property that it is because of its position in the space of contraries. That’s already to say that universality, being a determinate property, is articulated by relations of negation, of exclusive negation. And, I mean I should say the terms Hegel uses for these. ‘Exclusive difference’ is ‘ausschließender Unterschied’. That’s literally exclusive— ausschließen is to rule out and it’s probably worth keeping in mind that the term for drawing a consequence in German is ‘schließen’ and an inference is a ‘Schluß’, which is the result of doing that. But ausschließen, ruling out, it’s ausschließende, difference. That’s the exclusive difference. And he says it’s mere, bloße, or indifferent, gleichgültige, difference is the kind of difference that there is between red and square, where they’re not contraries. All right, but it’s these modally robust exclusive differences that determine, that articulate the contents of determinate properties or universals. Hegel will invoke, in other places, the Spinozistic doctrine “Omnis determinatio est negatio”, “All determination is negation”. Something’s determined insofar as it has a limit, beyond it it’s not. That’s what it is to be determinate. And he’s adding to Spinoza’s doctrine—yeah, and that’s exclusive negation, not mere negation. But there’s already a sense in which the identity of a property consists in its differences from other properties. Its unity, its self-relation, he’ll say, not entirely helpfully, depends on its relation to other things; indeed, consists in. What it is, consists in its relation to other things. And one of the overarching intellectual tasks that he set himself is to try and understand this kind of identity that consists in differences. And what we see here is his exploring the fine structure of those differences. So we said if we start with exclusive difference, we’ve seen we can get material consequences and we’ve seen we can get contradictories. We can get merely formal negation out of exclusive negation. And here we get a category, determinate properties or universals, officially all we’ve got is sense universals, coming out of sense certainty, whose identity consists in their exclusive differences from each other. That’s the first level. But now when we ask, well what do you mean by exclusive differences? What is the difference between exclusive difference and mere differences? Well, we see there has to be a unit of account. Exclusive differences are those that one unit can’t have both of, whereas mere differences are ones that one unit of account can have both of. Implicit in the distinction between exclusive and indifferent difference is the idea of a unit of account, which is going to be objects, particulars, things, thinghood in general he says here. But without that unit of account you can’t make sense of that difference between two kinds of difference. I mean, you can just think of them as, again, points of evaluation, but one point of evaluation can’t have two exclusively different properties associated with it, but it can have two merely indifferent ones. Only if you’ve got those points of evaluation or units of account can you make sense of that difference between two kinds of differences. Well, those units of account are categorially different from properties. Properties we can only make sense of as an ontological category by their relation to something that isn’t properties but is a unit of account for keeping track of the exclusive or mere difference between properties. So here’s a second sense in which the identity of the property consists in its difference. Now it’s the difference categorially, the inter-categorial difference between properties and objects. We started off with the intracategorial difference, exclusive differences between properties, but now that we see that those come in the two flavors, exclusive and indifferent, we’ve got to acknowledge something that isn’t a property, but is a unit of account for them. Now let’s think about those units of account for a minute. They by the very process by which we have uncovered them, extracted what was implicit in the idea of a difference between these two kinds of difference, they can stand in two different kinds of relations to properties. On the one hand, they are what Hegel will call the also or the medium in which properties that are only indifferently different are associated. So ‘The salt is white and it’s cubical and it’s tart’, that’s the also, being the medium of indifferently different, merely different, compatibly different properties. But it’s equally essential to being an object that they’re the units of account that exclude exclusively different properties. That is, because I’m host to white, I can’t be host to red and black and so on. Because I’m host to cubical, I can’t be host to spherical and so on. So on the one hand there’s a principle of inclusion of properties and on the other hand a principle of exclusion of properties. To be an object you’ve got to play both those roles. That difference between two relations that the objects can have to properties, that’s essential to what it is to be an object, that it stands in an inclusive also relation to some properties and an exclusive relation to other properties. That difference between its two kinds of relation to properties is of the essence of what it is to be an object or a particular. So not only is it essential categorially to objects that they be related to properties, but furthermore that they have these two different and opposed relations to properties is essential to what it is to be an object or a particular. So now we’ve got the intra-categorial differences, exclusive differences among properties, in virtue of which they’re determinately contentful; the inter-categorial difference between objects and properties, in virtue of which properties are what they are an objects are what they are; and we’ve got the difference within the object, within the category of objects now in two different relations that it stands to properties, which is an essential part of being of the category it is, of being an object. Now we can turn the crank one more time. And this is an argument that Hegel takes from Aristotle. We said we can construct from the notion of contrariety, from the notion of exclusive difference or determinate negation, we can construct the notion of formal negation by throwing away all the determinate differences between the contraries of something. So we can construct the idea of a contradictory of a property, of one that is, Hegel says, its opposite. And we do that just the way, I mean it’s another path through the same— exploiting the same structure, just the way that the, well just by reversing the way that the Tarskian order of explanation looked at these things. So the opposite of a property is the property that’s had by all and only the objects that don’t have that property. So we can get red, we can get to non-red. Non-red just is the property that’s exhibited by all the objects that don’t exhibit red. That’s the opposite of a property. What’s the opposite of an object? We have this symmetrical relation between objects and properties. The object has a bunch of properties. The property is true of a bunch of objects. We can define the opposite, the contradictory, of a property in this way. We have a property that applies to some objects and its opposite is the property that applies to all and only the other objects, the ones that that property doesn’t apply to. So what would the contradictory, the opposite of an object be? It would be an object that had all and only the properties that the first object doesn’t have. But what Aristotle already noticed is: there is no such thing. Because all the properties that a given object doesn’t have aren’t compatible with one another. They include things that are contraries of each other as well as things that are contraries of the objects they have here. So, my right thumb has the property of not being identical with Mozart. And it also has the property of not being identical with the phone that’s sitting on the table here. So the object that was the opposite of my thumb would have to be the property of being identical to Mozart and identical to the phone that’s sitting there, but it can’t have those. Those are exclusively different properties. Because of the way contraries work, objects can’t have opposites. Now that’s an inter-categorial asymmetry between objects and properties, which is a necessary feature of, in part constitutive of, the identity of those ontological categories, that properties have opposites and objects don’t. That’s another way of thinking about the relation between contrariety and contradictoriness. Hegel spent years thinking about this difference in Aristotle and the Dawn of Logic. And what we get is this result. If we start with this distinction between exclusive and mere difference, we can see that implicit in it is this fine structure of different kinds of identity and difference, different kinds of constructed negation. We can say objects and properties are in a certain sense categorially opposites of each other. They differ from each other in this constitutive way, namely that properties has opposites and objects don’t. That’s a category defining difference between objects and properties. To be an object, the identity of thinghood in general, as he says, consists in part, but essentially and necessarily in being different from properties in that it doesn’t have opposites. That turns out to be necessary for it to play the role of a unit of account for properties. That isn’t obvious when you just think about feature-placing. ‘It’s fine’ and ‘it’s night’. ‘It’s raining’ and ‘it’s night’. Those three different properties stand in the two different kinds of difference to each other. ‘Fine’ and ‘rainy’ are exclusively different, ‘fine’ and ‘night’ indifferently different, ‘raining’ and ‘night’ indifferently different. In that already is the identity of these two categories, the properties and the units of account for the properties, whose difference as ontological categories is constituted in part by this exclusive inter-categorial difference between them, namely that the one has contradictories and the other doesn’t. It because Aristotle saw that already that I call this structure of objects and properties Aristotelian. He was the first one to think through what it was about. Well, it’s this structure that starts with exclusive differences between properties as what the identity of the property consists in is its difference from its intra-categorial others, its exclusive difference. You can think of it as being the property it is as its position in the space of contraries. If, in the contemporary literature on the metaphysics of properties, if you identify properties by the nomological relations they stand in to other properties this is an instance of that kind of view, because these contrarieties are modally robust, they’re nomological relations. So that’s the first kind of identity and difference, just within the category of properties. But then we see that the difference between the exclusive difference and mere difference requires an inter-categorial difference—it requires units of account for these things—and that that intercategorial difference, that’s equally essential to what it is to be a property. It’s to be in this inter- categorial relation to things that are not properties, that are exclusively different from properties in a quite different sense than the sense in which contraries are exclusively different from one another. And when we think about these units of account and the relations that they stand in to the properties, we see that they stand in two quite different and opposed exclusive relations to properties: one of inclusion, the also, and one of exclusion. They’re units for both of those. And the difference between those relations between objects and properties, the difference between those is essential to the identity of objects as objects, as the kind of things that they are. And then we see that it follows from all of this that while properties can have contradictories, objects can’t, that these categories are asymmetric with respect to negations in yet a different way, that the identity of these ontological categories depends on this difference between them, depends on, is articulated, necessarily involves this difference. This is an order of explanation starting from exclusive difference of properties that gets us the full Aristotelian structure of objects and properties. It’s the converse, in a certain way, of the Tarskian order of explanation that is the foundation of modern logic and semantics, that starts with mere differences of objects, understand properties as different in terms of the mere differences of the objects they apply to, defines contradictoriness and formal negation by complementation within the domain and then defines contrariety in terms of implying the contradictory, and then builds in the modal character of these things once we go up to the KLS superstructure on the Tarskian structure. That’s one way of thinking about it. Hegel’s got a completely different metaphysical path through these ontological structures, one that builds the modality in at the base instead of having it come way at the end when we impose restrictions on what logically possible worlds are metaphysically or nomologically possible, that we never imposed on the model theoretic things. So this is the structure, this is I’m claiming the way he wants us to think about objects and properties. This is the order in which we extract different features of the fine structure of the relations of negation that are implicit in the idea of universality tout cour. There are all these different, more complicated kinds of difference that we can build out of that fundamental difference between two kinds of difference, between indifferent and exclusive difference. Now we’ve got the categorial difference between objects and properties; we’ve got the difference between the two kinds of relations between objects and properties, the inclusive and the exclusive one; we’ve got this difference of contradictories and no contradictories. All of these are kinds of identity through difference within the same category and across categories. We build all of them out of the basic ones and, he says, those basic ones I already gave you at the end of sense-certainty. We looking on could see that you were already committed to making this distinction just in seeing what’s expressed by feature-placing language as determinate only insofar as you could distinguish these two kinds of distinction. So this is the conceptual structure he wants us to grasp and it’s the background for all of the [?] things that he says here trying to find a language to say these. Student 2: I’m just wondering, on what grounds are we characterizing this as a metaphysical claim? So why not limit it to the epistemological at this point? Bob: Well, the “Perception” chapter has got the structure of an introduction in which he reminds us what we were getting from the previous chapter and sort of tells us where we’re going to end up. And then the three experiences of consciousness understanding itself as perceiving, that is understanding itself as applying sense universals which are immediate and as immediate are still conceived of as independent of their relations to anything else. You can’t have that, but that’s the conception. We get the three experiences of it and then a concluding thing that sums up and points us to the next one. The middle, the second of those experiences of perceiving consciousness, says “Can’t I help myself by going epistemological here?” I mean specifically what it’s doing is saying “I’m just a simple caveman. I can’t understand this identity consisting in differences. Maybe the identity is there ontologically and the differences are just epistemic.” No, turns out that won’t work. “Maybe the differences are there ontologically and I’m unifying these things epistemically.” No, that isn’t going to work. We’re going to have to say, well ontologically objects and properties have identity and difference and our thoughts must too, but if that’s true, if they have the same structure, how is error possible? Oh, don’t know yet, but we’ll find out going on. So I mean, the question you ask is up in the air. What is this a structure of? But it’s going to end up being the structure of both of them. And you know he’s going to need a term for what structure— determinate ways the world can be and determinate thoughts about it have to share and everything he said here is going to be amphibious between those. When all the dust has settled in the science of logic, he says, well this is the structure of logic, so it’s the structure of being and of thought. You know, philosophers need to be very careful when they’re giving an irritated response to somebody who really is missing the point that they’ve gotten and we have this sort of horrible history of Plato’s irritated response when someone asked him, “Where are these forms anyway?” “Oh they’re laid up in heaven.” If you’re silly enough to ask that question, then you’re silly enough to accept this answer. And suddenly we have NeoPlatonism and they say, “Ah, yes! But where is this heaven in which these things are laid out?” Taking literally in the preface to The Science of Logic Hegel sort of asking himself on behalf of some Wittgensteinian creatness [?] straight man “So what is this structure? What kind of thing is this anyway?” He says, “Ah, it’s the structure of God’s thought before the creation,” before there was a distinction between being and thought is the idea. Well, if you find that helpful, then he’s glad he said it and if not, don’t take it too literally. Atheist that he is, he doesn’t believe in creation and so on. So yeah, it’s a new kind of, it’s of a sui generis category, which he will call indifferently logical, philosophical, or speculative structure, and it has these aspects, ontological and epistemic. But I mean, I think it’s helpful obviously in the way I presented it to lay it alongside— Well, I mean is the Tarskian order of explanation an ontological— I mean, that’s a logical and a semantic way of thinking about things, but you better believe people take it metaphysically seriously, mostly these days under the heading of Humean metaphysics, and thereon hangs a different tale, but people certainly do think, well, if that’s the structure of what we can mean, then that must be the structure of the way things are. Or other people will say, “Oh, no, no, that’s a bad inference. You can’t read your ontology off of our semantics.” Ok, well, why don’t we take a twenty minute break and come back at five minutes of the hour and we’ll look at some actual text to see this going <word obscured by people getting up>. Ok, well, let’s look at some of the passages and see how much sense they make in the light of the story that I was telling. The introduction is really up through paragraph 116, is the introduction, so that’s mostly what I’m going to be looking at first, but I’m going to be jumping around in it. So in 114, he introduces the idea that the identity of the properties depends on their determinate differences from one another. So he says, “…if the many determinate properties were strictly indifferent (gleichgültig) to one another, if they were simply and solely self-related...” That’s a way he’s talking about unity, about identity, about the one as opposed to the many. “...if they were simply and solely self-related, they would not be determinate; for they are only determinate insofar as they differentiate themselves from one another…” That’s unterscheiden. “...and relate themselves to others as their opposites.” Als entgegengesetzte. “Yet; as thus opposed” (entgegensetzung) “...as thus opposed to one another they cannot be together in the simple unity of their medium, which is just as essential to them as negation...” So you’ve got the exclusive differences between them—that’s the first difference that their identity consists in. “Yet; as thus opposed to one another they cannot be together in the simple unity of their medium...” Their medium is thinghood in general, the particulars that exhibit them. “...which is just as essential to them as negation.” They can’t be together in it if they’re opposed. If they’re exclusively different, that precisely means they can’t be exhibited by the same object. And yet, that kind of unity, being in an Also, is as essential as their negations from one another are. So we’ve got a relatively complex structure. “...the differentiation”—that’s unterscheidung, rather than unterschied that would be different—”...the differentiation of the properties, in so far as it...is exclusive,” ausschließende “each property negating the others, thus falls outside of this simple medium...”, the medium being the objects. So he says you’ve got to think of the property as having these two kinds of relations—its intra-categorial relations of exclusive difference to other properties and its inter-categorial relation to the simple medium, the one, the thing, and yet it’s relation to the thing is just such that the thing excludes all those other properties, all the ones that are contraries of it. Again in 114, “if the many determinate properties...” Yeah, ok, all right. So then 114 continues, “The One”—objects—”is the moment of negation; it is itself quite simply a relation of self to self and it excludes an other; and it is that by which ‘thinghood’ is determined as a Thing.” So this is just saying that its role as a unit of account for exclusions, for exclusive differences, is essential to what it is for it to be one thing. Two things can have incompatible properties, but one thing can’t. So its identity as one thing essentially depends on its excluding some of the properties that it doesn’t have. Some of them it simply doesn’t have and others it excludes—the ones that are contraries of ones that it has. Still in 114, “Negation is inherent in a property as a determinateness which is immediately one with the immediacy of being”—now that’s because we’re talking about sense universals, so observable properties, ones that we can apply not as a product of and inference—”an immediacy which, through this unity with negation, is universality.” Now remember I quoted him saying the richness of content belongs to perception, not to sense certainty, not to immediate certainty, because only here is the content mixed with negation. And now we’re finding out mixed with negation is a very crude way of describing the intricately articulated structure that he’s got. “As a One, however, the determinateness is set free from this unity with its opposite, and exists in and for itself.” So it is a unity and what we’ve got to understand is the multifarious ways in which having the identity you do, being the unity that you are as an object depends on all of these contrasts, some of them exclusive, but even the exclusive differences have different kinds. The way the object excludes other properties is different from the way properties exclude other properties. The way the object is exclusively distinguished from properties in general—properties in general have opposites; it doesn’t—all of those are different. Here I thought it was useful to jump ahead a little. In 120, which is in the middle of the second experience of consciousness conceiving itself as understanding, he says, “...these diverse aspects for which consciousness accepts responsibility are specifically determined. White is white only in opposition to black, and so on, and the Thing is a One precisely by being opposed to others. But it is not as a One that it excludes others from itself...it is through its determinateness”—its properties— “that the thing excludes others. Things are therefore in and for themselves indeterminate; they have properties by which they distinguish themselves from one another.” I think this is a way of saying that objects are merely different from one another—they don’t have contraries, as well as not have contradictories—but their mere difference from one another, which is what makes them have the kind of unity that they do, consists in them having the specifically determined properties that they do, namely in excluding properties that are the contraries of those properties. So in 113, before those passages in 114 I was reading, he says the sense universal is a universal immediacy and I’m saying that just means it’s a sense universal. And 113 continues, “the medium in which these determinacies permeate each other in that universality as a simple unity...but without making contact with each other…” This is what later he’ll call the Also, all these indifferent properties that are properties of one and the same object are in it without interfering with one another. Its being cubical doesn’t interfere with its being white or its being tart, because those are all merely different. So he says they permeate each other in that universality. Now here the universality is the medium of one object and what it’s universal over is all of the properties, merely indifferent properties, that it’s got. It’s universal relative to those properties. Hegel does not, as far as I can see, distinguish here between properties as repeatables and properties as tropes. I think I mentioned that, for no very good reason, the recent literature has taken to using the word ‘trope’ for individual property instances, as opposed to properties that can have many instances. Ok, so when he says that it’s universal, that it’s the universality, the one object that has these many properties is a universality, a universal medium with respect to them, one might want to know, well is that a bunch of property tropes? Or is that a bunch of property repeatables that it’s universal with respect to? And I can’t pin him down as answering that question one way or another. Ok, “...for it is precisely through participation in this universality that each is on its own indifferent to the others.” Each is, on its own, the property that it is. It’s indifferent to the others—they can be co-exemplified. As it has turned out, “this abstract universal medium, which can be called ‘thinghood’ itself…is nothing other than” what in the previous section we called “the here and now…” Ok, part of the background to this is that in spite of the huge differences that there were between the Early Modern, pre-Kantian philosophers and the medievals—less than some people think. Former colleague Joe Camp has a very interesting article called “Descartes, the Last Scholastic”—all of them used basically Aristotelian principles of identity and individuation. Kant was the first one, because of his study of Newton, to use spatio-temporal principles to identify and individuate ordinary objects, to think of them as identified and individuated by their spatio-temporal location. That shift, from thinking about essence and accident to thinking about spatio-temporal principles of identity and individuation, vastly important in Kant—that’s why the aesthetic plays the role that it does—and Hegel is here saying, well look the reason the Here and Now played the role that they did in sense certainty already, we can now see the successor, sort of more filled-in notion of that is the pure thinghood. And he’s thinking of the things as being what were individuated by Here and Now, but he says they’re individuated by their properties. “This abstract universal medium, which can be called thinghood itself is none other than the here and now, namely, as a simple ensemble of the many.” It’s a one in which the many are unified. Ok, a couple of things from 114 that I think are still elaborating this picture I described. He identifies his topic. He says, as it turned out, “In this relationship, it is merely the character of positive universality which is at first observed and developed…” So we’re just looking to unpack the notion of universality. And he says, already in 114, “This simple medium is not merely an “also”,”—the Also of the many indifferently different properties— “an indifferent unity,” he says, “it is also a “one”, an excluding unity.” So here are the two aspects of objecthood, as inclusive relative to merely different properties and exclusive relative to exclusively different properties. In all of these things, I’ve been talking about the topic as being understanding unity as consisting in differences of different kinds. And we can already see that’s not just a vague slogan: identity consists in differences. Yes, he would accept that, but we’re seeing there’s a much more articulated structure of differences that he thinks the identity of an object or property consists in. He also will use the term for the kind of identity that consists in its differences—he’ll talk about it as the negation of the negation. The negation it’s the negation of is the differences that constitute the unity and it’s the negation of them in that it’s a unity created out of those differences. I think you don’t get anywhere in thinking about Hegel if you think there’s some one principle of the negation of the negation or of identity out of difference. Already just in talking about perceptible objects we see that there are many kinds of negation, many kinds of difference, and many kinds of identities formed out of them and an intricate, indissoluble structure of all of those. So just rehearsing these slogans—negation of the negation, identity through difference— that isn’t going to get you there. You’ve got to look at the fine structure of different kinds of differences, all of which, he’s claiming, can be elaborated from those two fundamental kinds of difference—mere difference and exclusive difference. So in 117 he says, “I now further perceive the property as determinate, as contrasted with another and as excluding it”. So that was our first point. “I thus in fact did not apprehend the objective essence”—well, the essence of objects—”correctly when I determined it as a community with others…” That is, as an Also, as a medium in which indifferent properties can be. And in terms “of the determinateness of the property, I must in fact break up the continuity into pieces”—the community into pieces—”and posit the objective essences”—the essence of objects—”as an excluding One...” So we got the object as an Also and the object as One—again the exclusive difference between those two roles with respect to properties that are essential to the identity of particulars or objects as such. And he says, “In the broken up One I find many such properties which do not affect one another but which are instead indifferent to each other.” Ok and in 115 he says, “...the Thing as the truth of perception”—he elsewhere calls it the Thing with many properties—”reaches its culmination to the extent that it is necessary to develop it here.” So here’s everything that we have extracted as implicit in the notion of universality in the form of the Thing of many properties and it is the “indifferent passive universality, the Also of the many properties of rather ‘matters’“—so that’s the Also—the “negation generally as simple; that is the One, the excluding of contrasting properties—that’s the other side of objects as exclusive—”and the many properties themselves” identified by their standing in relations both of exclusive difference to some properties and of indifferent difference to others, which is “the relation of the first two moments”. So that difference of two kinds of difference of properties is reflected in the difference between the object as Also and the object as excluding the One, so just as we can think of the object as the relation between those two roles, we can think of the properties as the relation between the two kinds of relations of difference that they stand in to other properties. The “negation as it relates itself to the indifferent element”—that’s the object— ”and extends itself within it is a range of differences;”—that the many properties in the Also— ”the point of…individuality in the medium of enduring existence radiating out into multiplicity.” And now here I think the “radiating out” means this is its role in excluding, this penumbra of contrary properties, this cloud of uninstantiated contrary properties that we can think of as surrounding every instantiated property. Those are all the ones that are repelled by it and that are not in the object. And there’s the others that are indifferent, that are not repelled by it because they’re not in this cloud of contraries around it. And what we’re going to find in the next section, where he’s worried about the supersensible world behind the sensible world, the one he’s really going to be worrying about is all of those uninstantiated possibilities, the ones that are excluded, in virtue of which the ones that are instantiated are the things they are—where are they? They’re not instantiated in the things and yet they’re essential to those properties being what they are and so to the object being what they are. Ask where they are that’s not right, but how are we to think of their presence, their activity in this thing. Ok, so I think every piece of the story that I was telling we see in those passages from 113 to 115 really and those are the ones where he’s not—where he’s just telling us how it is, this is where we’re going, I’m speaking in the order of exposition of the book to you the phenomenological consciousness, haven’t yet seen how any of this emerges in the experience of the phenomenal consciousness, the consciousness that understands itself as perceiving the thing of many properties. That will get three experiences, three movements of experience, in the sense of movements of experience, experience of error and so on that we saw in the introduction. So next I’ll say something about those three movements of experience, but let me stop here. At this point the hope is that you can understand what he’s saying in this sometimes extravagant language as talking about this other order of metaphysical explanation of the Aristotelian structure of things of many properties. Ok, well, the three experiences go like this. And let me say, I don’t have a really good story about why it’s just these three, why in this order, how they come out of one another. I think I understand the picture we’re supposed to get, that we get in those introductory paragraphs and in the concluding one. Exactly how these experiences give rise to one another is much less clear to me. So I’m going to give it my best shot, but I don’t think it’s that satisfactory. What I am confident of is, the first of them involves consciousness conceiving itself, understanding itself, under the categories of perception, of perceiving consciousness—that is, taking itself to be applying sense universals, which are immediate, both immediate in the sense of immediacy of origin, which they really are, and in the sense of immediacy as independence of relation to other things, as being self-contained or autonomous, and that’s the one that you can’t have. What it’s going to be experiencing are manifestations of the fact that the identities of everything it perceives are intelligible only in terms of their relations of multifarious kinds of multifarious other things, of properties to other properties, of properties to objects, of objects to those properties of objects to other objects. And the first of those experiences, which is just the long paragraph 117, is perceiving consciousness being bemused because it seizes on unity and that dissolves into multiplicity and when it asks, well what is the identity of these multiple items, that identity dissolves into further multiplicities. Furthermore, these are negations, oppositions. It just doesn’t understand what’s going on. So that first experience is realizing that there’s an issue, realizing that universality is fraught with negation, is articulated by negation. It doesn’t know how, yet, and it doesn’t understand how that can be. But it’s still seeing these as objectively in the things and the properties. In the second experience of consciousness, it tries out the strategy of—and I mean, I will go back and look in more detail at that first one; this is just the overview—it tries out the strategy of assigning identity and difference to different poles of the intensional axis. So it starts with objective unity and subjective diversity. The way things are is just the way things are but I see all these differences in it. And the second one as objective diversity which I unify. Now these correspond to Kantian and Shelleyan schemes. So the second one—Kant says, unity is everywhere and always the product of the intellect. What sense delivers is a manifold of intuition and any unification of it is the result of our activity. Namely, our synthetic activity. Unity is the product of intellectual activity. That’s what the understanding does: it unifies things. And because he thinks the mind is best known to itself, he thinks what we’ve done we should be able to understand and analyze. So we ought to be able to analyze these unities, since they’re our products. This is Kant now. I call the other scheme Shelleyan because of this passage in his poem Adonis. He says, “The One remains, the many change and pass;/ Heaven’s light forever shines, Earth’s shadows fly;/ Life, like a dome of many-coloured glass,/ Stains the white radiance of Eternity.” So we’ve got the white radiance of Eternity, Heaven’s light that shines forever, and life is this dome of multi- colored glass that breaks it up, stains it with colors, and gives us this multi-colored appearance. So that’s the opposite of the Kantian picture—the white radiance of Eternity is unified until it gets to our jumbled, colored pieces of glass that create this other view. Now whether thinking about this epistemologically or ontologically, this was a battle that was fought out with the British absolute idealists between Bradley and Russell just before the turn of the century. Russell, in his characteristic style, says the question is whether the universe is to be conceived of as a bucket of shot or as a bowl of jelly. If it’s a bucket of shot then you’ve got to pick up—he’s thinking of shotgun shot, so that’s all these little BBs—you’ve got to pick up some of them and keep them from rolling out of your hand. You’ve got to keep them together, but you can pick up different ones. Or if it’s the bowl of jelly you’ve got to carve something out of it with a spoon, out of the goo, and where those distinctions are made that will be your contribution. Again, thought of ontologically this was the view that Russell was giving us a metaphor for. And in contemporary analytic metaphysics you’ve got your goo universe and your atomistic universe too. This is still going on or going around again on the merry-go-round, depending on how you think it. Bradley’s way of putting this, which Russell took over, was to distinguish between internal and external relations. Internal relations are—the paradigm is relations between the parts of a thing—they’re the relations without which the thing wouldn’t be the thing that it is. And the external relations are the relations that are not essential to its being the thing that it is. So paradigmatically, in the example F.H. Bradley uses, the relation between the rungs and the rails of a ladder are internal relations. If you separate the rungs from the rails, you don’t have a ladder any more. A ladder is rails related to rungs in a ladder-like way. The relation between the ladder and the wall that it’s leaning up against—that’s an external relation. You can have the same ladder leaning up against a different wall. But the relation among its parts, rungs to rails, that’s internal to it. And in characteristic, late 19th century metaphysical fashion the two options available were absolute idealism, all relations are internal relations, and Russellian atomism, all relations are external relations. One of the ways the American pragmatists sometimes conceived themselves was saying, there, there. There really are some internal relations and some external relations. You know, don’t go berserk with this. And Russell’s friend Whitehead coined the name the fallacy of lost contrast with this as a paradigm instance of that. So look the distinction between internal and external relations in the case of the ladder makes perfect sense, as a distinction, but now if you say all there is, in principle, in the universe is internal relations, the distinction with external relations that was necessary to make the notion of internal relations coherent is gone—fallacy of lost contrast. And by the way, you, Russell, are in the same position. You can’t say, “Well yes that’s foolish. They’re really all the relations there are external relations.” Again, fallacy of lost contrast. This was their way of talking about what earlier generations would have talked about as essential or accidental, but now in the mode of relations. This is Bradley’s way of being a holist. It’s put in literary form in Wordsworth’s [Note: this is actually by Tennyson] Flower in the Crannied Wall, when he says, “Ah, but for me to really understand this part of the universe I would actually have to understand everything.” It’s relation to a butterfly in China, that’s really internal to this flower in the crannied wall. That was what Bradley was giving philosophical voice to and Russell, no, the atomism on the other side, talking about what were essential relations and what were not— they’re all essential; no, none of them are essential. Quine in ‘Two Dogmas of Empiricism’ says, “Meaning is what essence becomes when it’s divorced from the thing and attached to the word.” And I think this is a deeply resonant passage. He’s looking at semantics, theory of meaning, and saying, “You know, we may think this debate about buckets of shot and bowls of jelly is really old-fashioned and we know better than to worry about that, but a debate of exactly the same structure is happening in semantics, where the holists, like me Quine by the way, say all semantic relations are internal relations. The meaning of something is a matter of its role in the whole web of belief—its relation to everything else, all those relations are equally essential to it. You can’t make an analytic/synthetic distinction. That would be the distinction between semantic internal relations and semantic external relations. That just is the analytic synthetic distinction.” And he’s saying, no they’re all equally analytic, equally synthetic. They’re all reacting to that, people like Fodor say, “No, there are these, glassy essences, these atomic units of meaning and what we have to do is put them together in various ways.” But Quine was indicating that there are parallel issues, either on the side of ontology or on the side of semantics. “Meaning is what essence becomes when it’s detached sic from the thing and attached to the word.” The very same sorts of disputes come up. Hegel is going to claim to leap over this whole structure of debate in both of its forms, but worrying about the relation between them and this middle experience, second experience of consciousness understanding itself as perceiving consciousness, is his first shot across the bow, his first effort to say, “Look, neither the Kantian mind is the source of all unity nor the Shelleyan life is the dome of many colored glass refracting the white radiance of eternity—neither of those is going to do justice to the intricate ways in which identity and difference are interdigitated and articulated, both on the side of determinate facts—the fact that something has properties—and on the side of the thoughts that express those facts. So I mean it is only the opening salvo in this but it’s an important thing. The third—I’ll also come back to talk about that in more detail insofar as I have time, if not it’ll be in the notes. The third experience is a very interesting one and particularly interesting in the light of subsequent philosophical developments, a lot have escaped your attention but I often think of stuff that happened later as casting light on the earlier thing. The third strategy that perceiving consciousness tries out in order to make sense of identity and difference says really this talk about different properties, exclusively different properties, is talk about the relations among objects. To have different properties is to be related to two different objects. We can understand all of this in terms of mere differences of objects and of relations between objects. Now this view has a lot in common with what I called the Tarskian order of explanation, but there’s more to it than that. The diversity that makes an object determinate is thought about as exclusively consisting in its relation to other objects. And there’s going to be a kernel of the truth in this. This is the third experience which is going to take us to the “Force and Understanding” chapter. There’s a holist truth in there that isn’t yet explicit, but what I want to emphasize is this is a Tractarian conception. Noticeably in the Tractatus there aren’t monadic properties. What would it be for them to be different? The Tractatus has merely different elementary objects and merely different relations among those objects. To talk about a property in the Tractatus is to talk about different relations to objects. You’re always abstracting from some multiadic property and, of course notoriously, every elementary object can stand in every relation to every other elementary object. That is, there is no relation of contrariety or exclusive difference among the properties that are emergent from these relations among objects. Every combination is logically possible and there is no other sort of modality than the logical in the Tractatus. Now probably not coincidentally, it seems to have been when he was working on his lectures on color that Wittgenstein decisively moved away from his Tractarian conception. If colors weren’t elementary features, what were? And yet it seemed to be an essential feature of them that they stood in these contrariety relations that the Tractatus had no room for. And it was in starting to think about those that he moved into the Blue and Brown Book middle period. Anyway, the claim I want to make is that this third experience of consciousness, the strategy that dissolves there is a recognizably Tractarian strategy that’s going to use relations among objects to stand in for the properties as a way—the hope is—of reconciling the identity of objects as standing in—well, as being determinate, but instead of thinking that as having many properties, it’s thinking of it as standing in relations to many objects. That’s the strategy. Ok. Well, we’ve got time to look at least at the first one of these and maybe more. So, this is all in paragraph 117, but I think there’s three moves and we have to sort of decide what’s up with it by looking at those three moves. So the first one is, “The object which I apprehend presents itself purely as a One…” So we start with experience of the unity, the identity—we’ve got the One there. “…but I also perceive in it a property which is universal, and which thereby transcends the singularity of the object.” It’s a universal. It can apply to more than one thing. So maybe that does tell against it being a trope that we’ve got. “On account of the universality of the property, I must rather take the objective essence to be on the whole a community.” Now this is actually not the way I would have used his language, given what he says in 114/115. I would have thought that what made me see the object as a community was seeing that it had more than one property, that it had merely different properties in it. But maybe he’s saying here that’s a consequence of identifying this property. Its being at least merely different from the others makes me see the One as a community. If not, what he’s saying by seeing the One as a community is it’s being grouped into a community by the universal. We’ve got this repeatable property that characterizes it and that’s creating a relation between this object and all the other objects that share that property. That’s, I would say, not to see it as a community, but as a member of a community. So I mean that reading follows better from seeing it as just one universal, one property, but then it’s a little awkward. He should say he sees it as a member of a community there. So ok, but that’s the first move. The second move— “I now further perceive the property to be determinate, opposed to another and excluding it.” So he’s started, the object that I see there’s this universal thing in it, that was what I learned from sense certainty. Now I see that it’s determinate and what that means is excluding others. But now that’s going to mean, that’s going to show that it was incorrect to think of the property as just unifying its instances, putting them into a community. That’s an inclusion, seeing the property as including. Now I’m seeing it as excluding as well and how am I to understand the relation between those two things? And then the third move, “In the broken up One I find many such properties which do not affect one another but are mutually indifferent.” So, all right, this I think is saying—it’s only now that he’s got the multiplicity of properties, so the universal was seeing the object as falling into a group, into a community of other like-propertied things. So at the previous stage it was noticed that each property instantiated by a particular object excludes the instantiation by that object of many others, and now it’s noticed that the object also includes many such excluding properties. So to continue the passage, so now it, the object, is a universal common medium. So we’ve gone from thinking of the universal as creating a community to thinking of the object as “a universal common medium in which many properties are present as sensuous universalities”—observable properties—”each existing on its own account and, as determinate, excluding the others.” But now, how can it both be existing on its own account, be just the property that it is, and be determinate only in virtue of excluding the others? Well, since it’s true of properties that, quote: “Only when it belongs to a One is it a property, and only in relation to others is it determinate.” That’s the conclusion of its experience here. Those are two essential features of properties that it can’t see how to get together. It has to be related to an object, but it has to be related to these properties in an exclusive way as well. So, I mean, I’m inclined to see that as merely setting the problem. It’s noticing these features which in 113 through 115 he’s told us how to think about, how he wants us to think about them, and here we just see, well, the phenomenal consciousness over whose shoulder we’re looking can’t do that. So let’s look a little more closely at the second strategy, the second experience, which is 118 to 120. Well, I’ve said a lot about this, so let me just read some of it. In 118, “for consciousness it has thereby been determined just how its perceiving is essentially composed, namely,…not as a simple pure act of apprehending”—it was still supposed to be immediate universality—”but rather as being in itself an act of apprehending at the same time taking a reflective turn into itself from out of the True.”—Because it’s finding these opposed aspects in what it’s doing. It’s not just taking it in anymore.—”This return of consciousness into itself which immediately blends itself into that pure apprehending”—he’s saying, well what I’m immediately apprehending is the thing of many properties, but again how can that be? The pure apprehending and these other…—”has been shown…to be essential to the act of perceiving”— well, sorry, I’m... “This return of consciousness into itself which immediate blends itself into that pure apprehending, for…it’s been shown…to be essential to the act of perceiving”—that reflective return into itself alters the true. Well, remember the emergence of the second new true object at the end of the introduction. The new true object, the alteration that occurs, is what I took to be the way things were in themselves, now shows up merely as the way they were for me, for consciousness. And he’s now realized, oh, there’s more to this apparently simple apprehending than just that. I’m doing something. I’m distinguishing the thing from the properties, the properties from the properties, and beginning to see this intricate structure. So he says, “The conduct of consciousness which is now up for examination is so composed that it is no longer merely the act of perceiving, but it’s conscious of its reflective turn into itself, and it separates this reflective turn into itself from simple apprehension itself.” So this is the point at which the idea becomes available to it that maybe part of what it’s perceiving is the result of its activity. Now since the problem was getting unity and diversity, the one and the many, together, content and negation, now it thinks, well, maybe I’m responsible for one of those and the other one is out there. So that’s where these two ideas come from. And you can do 119 and 120 which deal respectively with the Shelleyan and the Kantian scheme. Roughly the idea is just what we saw at the beginning of the introduction. Either of those make its perception that’s supposed to be immediate apprehension a falsification. If it’s adding unity or if it’s adding multiplicity, either it’s synthetic activity or the dome of many colored glass refracting it—either of those things is falsification. So he devotes most of the space—120 to 127 anyway—to this third alternative. That’s the one that’s going to give rise to next week’s account. Here’s some passages from that. So in 123, “the Also, that is the indifferent distinction,…falls just as much into the Thing as it does into oneness”—So we’ve got these two aspects, the particular as the Also that unifies the merely different properties and as the excluding One that excludes all the properties that are in the cloud around each of the instantiated properties.—”...falls just as much into the Thing as it does into Oneness, but since both are different it does not fall into the same Thing but rather into different Things.”—That’s the idea now is we’re going to look at these two aspects of the Oneness of the thing as involving relations to different objects.—”The contradiction which exists per se in the objective essence”—I mean, objective essence, this is the third time this has come up. That’s a literal translation of the German, but the essence of the object or the essence of what it is to be an object would be better—”is distributed into two objects.”—So instead of its being in that object and the subject we’re now distributing into two objects. So in 124, “the various Things are therefore posited as each existing on its own...”—So each one is what it is and not some other thing. They’re at least merely different, these objects.—”...and the conflict falls into each of them reciprocally such that each is different, not from itself, but only from the others.” The trouble with conceiving the identity of the object as consisting in its differences, in the difference of it from its properties and in the two different relations it stands in to properties, one inclusive and one exclusive, it seems like a difference from itself. That’s not the form of an identity. “...each is different, not from itself, but only from others.” So Tractarian conception—we’ve got these merely different objects and any difference that we find in one object is going to be a matter of relations to different objects. “However, each is thereby itself determined as something distinct and has the essential distinction from others in it.” If they’re numerically distinct, as is sometimes that they’re merely different, still there has to be some content to that difference. But at the same time not in such a way that this would be a contrast in itself. “Rather it is on its own simple determinateness which constitutes its essential characters, and distinguishes it from others.” Now in contemporary metaphysics, this would be called haecceity. Haecceity, I guess that’s Duns Scotus originally, is the this-ness of something. It’s the property of individuality, of being this thing and not some other thing. That’s an interesting kind of property to conceive, but you know it’s not a property like being red—that’s clear—but that’s what’s being tried out here. Well, there is some differences, some this-ness, some particularity that this thing has and a different one that this thing has that doesn’t dissolve into have different properties. So the less plausible side of Leibniz’s Law is the identity of indiscernibles, saying that if two things have the same properties then they’re really one thing. The more plausible side is the indiscernibility of identicals—if two things are identical then they have the same properties. Haecceities are a way of denying the identity of indiscernibles. And remember, it was very important to Kant to see space and time as not properties but as able to distinguish indiscernibles—his two hands, sitting in space, different, his right hand and left hand, but no different properties that they had. There’s a huge discussion of this example, but this view— well, there could be merely different things, even if they shared all the same properties. Haeccetism is the view that that’s intelligible. I think that’s reading model theory into ontology, but ok. Yeah, so he considers that. But he finds in 127 that this is not a coherent conception of determinateness. So he’s going to have the phenomenal perceiving consciousness reject this notion of haecceitism as unintelligible. And we hear for that reason in 128 that the object is the opposite (Gegenteil) of itself. Now that’s the very term that we use when we talk about properties having opposites, having contradictories, and of course Hegel reminded us in the earlier part that objects don’t have opposites. So we’ve gotten into a bad place. So in 129, “from out of sensuous being it became a universal; but…since it emerged from the sensuous, this universal is essentially conditioned by the sensuous, and thus is not truly in parity with itself.”—Well, it’s not truly identical, selfidentical—”Rather it is a universality affected with an opposition, which for that reason is separated into the extreme terms of individuality and universality.” So we see that the very notion of a universal, even if it’s a sense universal, implicitly involves the categorial distinction between particulars and universals. That is to say, the passage goes on, “of the One of…properties and the Also of the free-standing matters.”—the One of the properties that are excluded and the Also of the free-standing matters—”These pure determinatenesses seem to express essentiality…itself”—what it is to be an object—”however, they are only a ‘being-forself’ which is burdened with…’being-for-another’.”—Now here, the being for self, that’s not a being for consciousness, but that’s a unity that is burdened by consisting in its relations to some other things.—”But since…both exist in one unity,…unconditioned absolute universality itself is now on hand, and for the first time consciousness truly enters into the realm of the Understanding.” That is, realizing that these things must go together, even though it doesn’t understand it, it’s now set itself in the level of understanding. So in a summary in 130, “the sophistry of perceiving seeks to save these moments”—identity and difference—”from their contradiction,…to hold fast to them by distinguishing various points of view, by invoking the ‘Also’ and…’insofar’, as well seeking finally to lay hold of what is true by distinguishing the unessential from an essential that is opposed to the universal. Yet all of these expedients”—the three experiences—”instead of warding off illusion and apprehension, prove themselves…to be rather nothing at all; and the true which is supposed to be won through this logic of perceiving proves to be in one and the same regard the opposite and thereby to have as its essence that universality completely devoid of distinction and determination.” So none of those strategies is going to get you determinate universals. So ok, well, I hope you’re in a position now—this is again, what?, 111-130, we’re talking about twenty paragraphs. This is a manageable stretch of text. There’s really a lot going on in this and I keep making reference to contemporary analytic metaphysics. That’s a house with many mansions. There is nobody running the Hegelian line that he’s running here. Nobody’s trying that out in contemporary metaphysics. Somebody surely ought to be addressing their problems in these terms, but when you say Hegelian metaphysics people don’t think of this particular constellation of ideas. So “Force and Understanding” next time. Here’s the key thought to keep in mind when you read it: force is the paradigmatic Newtonian, theoretical concept and Hegel uses force to mean theoretical objects. Force is just the paradigmatic one, but it’s the whole class of things that are not observable, properties that are theoretically postulated. I will post some more detailed discussion. There is some more detailed discussion that I didn’t get into in the notes and I will post that on the website.
