PHIL 440 (FALL 2006) INSTRUCTOR: WILBURN SESSION 4 LECTURE NOTES 9/21/06 Last Week: We looked at Chisholm's account of foundationalist justification, which is the main one that we will be examining (even though we’ll look at a slightly different one later, in a couple of weeks). This week we’ll look at two papers by Bonjour, the first one criticizing all forms of foundationalism (with regard to empirical belief), and the second endorsing an alternative coherentist account of justification. 1.2 CAN EMPIRICAL KNOWLEDGE HAVE A FOUNDATION? Laurence Bonjour Again, what is the doctrine of the given??? “the claim that certain empirical beliefs possess a degree of epistemic justification or warrant which does not depend, inferentially or otherwise, on the justification of other empirical beliefs, but is instead somehow immediate or intrinsic.” Bonjour doesn’t underestimate it. Why does Bonjour compare it to a hydra? Bonjour’s goals in this paper: (1) Unify the problem – “distinguish and clarify the main dialectical variants of foundationalism, by viewing them as responses to one fundamental problem which is both the main motivation and the primary obstacle for foundationalism.” (2) Criticism empirical foundationalism of all stripes – “offer schematic reasons for doubting whether any version of foundationalism is finally acceptable.” What is the fundamental problem that motivates foundationalism and makes it see inevitable? The regress problem – What is this again??? Bonjour agrees with Chisholm as to what the four potential solutions to the regress problem would have to be like. (i) The regress might terminate with beliefs for which no justification of any kind is available. 1 What’s wrong with this??? (ii) The regress might proceed infinitely backwards with ever more new premise beliefs being introduced and then themselves requiring justification. What’s wrong with this??? (iii) the regress might circle back upon itself, so that at some point beliefs which appeared earlier in the sequence of justifying arguments are appealed to again as premises. What’s wrong with (iii)? Bonjour writes, “Although the problem of the knower having to have an infinite number of beliefs is no longer present, the regress itself, still infinite, now seems undeniably vicious. For the justification of each of the beliefs which figure in the circle seems now to presuppose its own epistemically prior justification: such a belief must, paradoxically, be justified before it can be justified.” (iv) The regress might terminate because beliefs are reached which are justified—unlike those in alternative (i)—but whose justification does not depend inferentially on other empirical beliefs and thus does not raise any further issue of justification with respect to such beliefs. Choice (iv) is the foundationalist’s option. The foundationalist considers it the only choice left standing after all these objections have been considered. Bonjour wants to argue that that it really doesn’t survive these objections because it itself falls prey to something like the regress of justification problem. “The epistemic regress argument will prove to be a two-edged sword, as lethal to the foundationalist as it is to his opponents.” Two interpretations of alternative (iv): Strong vs. weak. What is that??? Strong foundationalism: “According to strong foundationalism, the foundational beliefs which terminate the regress of justification possess sufficient epistemic warrant, independently of any appeal to inference from (or coherence with) other empirical beliefs, to satisfy the justification condition of knowledge and qualify as acceptable justifying premises for further beliefs. Since the justification of these basic beliefs, as they have come to be called is thus allegedly not dependent on that of any other empirical belief, they are uniquely able to provide secure starting-points for the justification of empirical knowledge and stopping-points for the regress of justification.” (Note that this is not a certainty claim.) Weak foundationalism: “[This] is a view which may be called weak foundationalism. 2 Weak foundationalism accepts the central idea of foundationalism—viz. that certain empirical beliefs possess a degree of independent epistemic justification or warrant which does not derive from inference or coherence relations. But the weak foundationalist holds that these foundational beliefs have only a quite low degree of warrant, much lower than that attributed to them by even modest strong foundationalism and insufficient by itself to satisfy the justification condition for knowledge or to qualify them as acceptable justifying premises for other beliefs. Thus this independent warrant must somehow be augmented if knowledge is to be achieved, and the usual appeal here is to coherence with other such minimally warranted beliefs.” Why does he make this distinction? To point out that his objection is a very broad one, applying to both strong and weak forms of foundationalism. The central question that Bonjour asks: What could make a belief basic or foundational??? To answer this, he asks what the difference is between epistemic justification and other kinds of justification. . . e.g., moral justification . . . Epistemic justification alone has an “essential or internal relationship to the cognitive goal of truth.” This suggests something about the essential nature and function of basic epistemic beliefs. If basic beliefs are to provide a secure foundation for empirical knowledge, if inference from them is to be the sole basis for the justification of other empirical beliefs, then that feature, whatever it may be, in virtue of which a belief qualifies as basic must also constitute a good reason for thinking that the belief is true. If we let "f" represent this feature, then for a belief B to qualify as basic in an acceptable foundationalist account, the premises of the following justificatory argument must themselves be at least justified: 1. Belief B has feature (f). 2. Beliefs having feature f are highly likely to be true. 3. Therefore, B is highly likely to be true. Now comes the most general form of Bonjour’s argument: “. . . if we now assume, reasonably enough, that for B to be justified for a particular person (at a particular time) it is necessary, not merely that a justification for B exist in the abstract, but that the person in question be in cognitive possession of that justification, we get the result that B is not 3 basic after all since its justification depends on that of at least one other empirical belief. If this is correct, strong foundationalism is untenable as a solution to the regress problem (and an analogous argument will show weak foundationalism to be similarly untenable).” What is Bonjour saying? So, the problem is with which principle? (1) or (2) How might we keep (2) from posing a problem??? Why does he start talking about externalism, this account of Armstrong’s??? First, what is Armstrong’s account of what it is to be justified in holding a basic or noninferential belief? What is he trying to accomplish when he writes this: “What makes a true non-inferential belief a case of knowledge is some natural relation which holds between the belief-state...and the situation which makes the belief true?” in particular, where “there is law-like connection between the state of affairs Bap [i.e. a's believing that p] and the state of affairs that makes "p" true such that, given Bap, it must be the case that p." This purports to address the regress problem is very simply. On this account, the person who has a basic belief need not be in possession of any justified reason for his belief. Look at the form of Armstrong’s account: 1. Belief B is an instance of kind K 2. Beliefs of kind K are connected in a law-like way with the sorts of states of affairs which would make them true, and therefore are highly likely to be true. 3. Therefore, B is highly likely to be true. The second principle seems to simply replace the demand for justification with something completely different? So, what is your reaction? Is Armstrong actually dealing with the problem of justification 4 or has he simply changed the subject. Why does Bonjour write this: “It is clear, of course, that an external observer who knew both that P accepted B and that there was a law-like connection between such acceptance and the truth of B would be in a position to construct an argument to justify his own acceptance of B. P could thus serve as a useful epistemic instrument, a kind of cognitive thermometer, for such an external observer. But P himself has no reason at all for thinking that B is likely to be true . . . From his perspective, it is an accident that the belief is true. And thus his acceptance of B is no more rational or responsible from an epistemic standpoint than would be the acceptance of a subjectively similar belief for which the external relation in question failed to obtain.” So, Bonjour has this reaction to externalism (which I share): It simply changes the subject. Think about skepticism . . . However, considered more generally, it is a specific form of a type of strategy which needn’t change the subject. There is another variant of this type of strategy which is, in fact, precisely what the traditional foundationalist tends to have in mind when he asks after basic or foundational beliefs. This is the traditional Cartesian doctrine of cognitive giveness. How would you characterize this notion??? “basic beliefs are justified by reference, not to further beliefs, but rather to states of affairs in the world which are "immediately apprehended" or "directly presented" or "intuited." How is this like externalism similar and different in its response to principle (2) of the original foundationalist strategy, e.g., 1. Belief B has feature (f). 2. Beliefs having feature f are highly likely to be true. 3. Therefore, B is highly likely to be true. ??? How is it similar??? 5 In both cases one’s empirical beliefs are ultimately grounded in some kind of direct appeal to non-cognitive reality. How’s it different??? In the case of externalism the justifying state of affairs is part of the world itself, whereas in the case of classical givenism the justifying state of affairs is part of how the world is apprehended by the perceiver. Note again that we need not assume here that the classical given need not be known with certainty or indubitability. But why would philosophers ever think that it would be amenable to some kind of special epistemic privilege??? So, this is the idea so far: 1. Belief B has feature (f). 2. Beliefs having feature f are highly likely to be true. 3. Therefore, B is highly likely to be true. where belief B is of the form “My immediately apprehended state of affairs is such and such” and feature (f) is the feature that my this belief has of being somehow sourced or prompted by immediately apprehended state of affairs actually being such and such. What is important is that this immediately apprehended state of affairs is not itself a belief or any sort of cognitive state since, if it were, it too would require further justification. Now, we are finally coming to Bonjour’s most substantive point. On the above account, there are three items involved in our having a foundationally grounded belief: B (the belief) e.g., that I am having a yellow sensation The state of affairs that my belief is about, e.g., the yellow sensation The intuition or immediate apprehension of that state of affairs, e.g., my immediate apprehension of that yellow sensation The problem Bonjour sees is with the last of these three, e.g., the intuition or immediate apprehension of the yellow sensation. We’ve specified that it is not a belief or cognitive state of any kind. It has to be noncognitive. But this makes it difficult to see how it could justify B. 6 Classically, Lewis and Quinton and others suggest that my immediate apprehension of that yellow sensation is an item of which I am "directly aware". But unless we lapse into marginally intelligible and completely non-informative metaphors concerning the “mind’s eye”, it’s hard to see what “direct” could mean here other than simply non-inferential. Conclusion: the givenist is caught in a fundamental dilemma: if his intuitions or immediate apprehensions are construed as cognitive, then they will be both capable of giving justification and in need of it themselves; if they are non-cognitive, then they do not need justification but are also apparently incapable of providing it. This, at bottom, is why epistemological giveness is a myth. We cannot simply stipulate that our direct-knowledge-yielding acts of non-cognitive apprehension are semi-beliefs, providing justification but not requiring justification without being ad hoc. Consider a parallel case: The problem of free will. A more specific analysis of the problem in this particular instance: The basic idea, after all, is to distinguish two aspects of a cognitive state, its capacity to justify other states and its own need for justification, and then try to find a state which possesses only the former aspect and not the latter. But it seems clear on reflection that these two aspects cannot be separated, that it is one and the same feature of a cognitive state, viz. its assertive content, which both enables it to confer justification on other states and also requires that it be justified itself. If this is right, then it does no good to introduce semi-cognitive states in an attempt to justify basic beliefs, since to whatever extent such a state is capable of conferring justification, it will to that very same extent require justification. THE COHERENCE THEORY OF EMPIRICAL KNOWLEDGE Laurence BonJour In this paper, Bonjour offers his alternative to foundationalist accounts. Mainly, he wants to show that coherence theory is itself coherent, that it doesn’t fall prey to obvious and overwhelming objections. Why go this way? How would you describe the fundamental confusion that Bonjour thinks foundationalist accounts suffer from??? Confrontation??? CTEK (Coherence Theory of Empirical Knowledge): The most basic idea is that the relation between the various particular beliefs is not one of linear dependence; but one of mutual or reciprocal support. How does it answer the regress concern??? 7 “There is no ultimate relation of epistemic priority among the members of such a system and consequently no basis for a true regress.” “The component beliefs are so related that each can be justified in terms of the others; the direction in which the justifying argument actually moves depends on which belief is under scrutiny in a particular context.” “The apparent circle of justification is not vicious because the justification of particular beliefs depends finally not on other particular beliefs, as in the linear conception of justification, but on the overall system and its coherence.” First of all, what is coherence??? (1) Coherence is not to be equated with consistency. A coherent system must be consistent, but a consistent system need not be very coherent. Coherence has to do with systematic connections between the components of a system, not just with their failure to conflict. (2) Coherence is a matter of degree. For a system of beliefs to be justified, according to the CTEK, it must not be merely coherent to some extent, but more coherent than any currently available alternative. (3) Coherence is closely connected with the concept of explanation (and prediction). Unificationist theory of explanation. That’s the idea. What are the objections to it? All have to do with the question of how coherence can be equated with justification. Why is that an issue??? Here are the objections. Let’s talk about them. (I) According to the CTEK, the system of beliefs which constitutes empirical knowledge is justified solely by reference to coherence. But coherence will never suffice to pick out one system of beliefs, since there will always be many other alternative, incompatible systems of belief which are equally coherent and hence equally justified according to the CTEK. (II) According to the CTEK, empirical beliefs are justified only in terms of relations to other beliefs and to the system of beliefs; at no point does any relation to the world come in. But this means that the alleged system of empirical knowledge is deprived of all input from the world. Surely such a self-enclosed system of beliefs cannot constitute empirical knowledge. 8 (III) An adequate epistemological theory must establish a connection between its account of justification and its account of truth; i.e., it must be shown that justification, as viewed by that theory, is truth-conductive, that one who seeks justified beliefs is at least likely to find true ones. But the only way in which the CTEK can do this is by adopting a coherence theory of truth and the absurd idealistic metaphysics which goes along with it. First, deal with (II). Then use these results to deal with (I) and (III). Again, (II): According to the CTEK, empirical beliefs are justified only in terms of relations to other beliefs and to the system of beliefs; at no point does any relation to the world come in. But this means that the alleged system of empirical knowledge is deprived of all input from the world. Surely such a self-enclosed system of beliefs cannot constitute empirical knowledge. Distinction: B is non-inferential iff B is not actually arrived at on the basis of inference from other beliefs. (Psychological Inferential -- Ipsy) B is non-inferential iff B is not warranted on the basis of inference from other beliefs. (Logical Inferential -- Ilog) Bonjour’s strategy: Show that the world can impact our beliefs through observation, even though all the warrant for these observation statements is, strictly speaking, Logical Inf Example: Belief P – “There is a black soda can on the desk.” This belief is cognitively spontaneous (not Ipsy) Bonjour needs to explain how it is still Ilog. The form this explanation takes: 1. B is a visual belief, i.e. it is produced by my sense of sight; and I am, or at least can be, introspectively aware of this fact. 2. The conditions of observation and attention are such and such: the lighting is good, my eyes are functioning normally, and there are no interfering circumstances, etc. 3. I have spontaneously have visual belief P. 9 4. If 1-3 are true, then P is likely to be true. 5. Thus, P is likely to be true. In short, the reason that visual perceptual beliefs are epistemically justified or warranted is that we have empirical background knowledge which tells us that beliefs of that specific sort are epistemically reliable. This is the basic claim of the CTEK for all varieties of observation. “First, there must be a process of some sort which produces cognitively spontaneous beliefs about a certain range of subject matter. The process involved may be very complicated, involving such things as sense organs; the state of the mind and/or brain as a result of previous training or innate capacities; perhaps also the sorts of entities or events which philosophers have variously referred to by such terms as "immediate experience," "raw feels," and "senses"; instruments of various kinds; perhaps even occult abilities of some sort (such as clairvoyance); etc.’ “Second, “the beliefs thus produced must be reliable with respect to the subject matter in question in the two distinct ways discussed above (under specifiable conditions): on the one hand, it must be very likely that such beliefs, when produced, are true (if the requisite conditions are satisfied); and, on the other hand, if the person is in a situation in which a particular belief about that range of subject matter would be true (and if the requisite conditions are satisfied), then it must be very likely that such a belief will in fact be produced. This second sort of reliability is crucial; on it depends, in large part at least, the possibility of negative observational knowledge.” “Third, and most importantly “from the standpoint of the CTEK, the person must know all of these things, at least in a rough and ready way. He must be able to recognize beliefs which result from the process in question (though he need not know anything about the details of the process). He must know that such beliefs are reliable in the two senses specified. And he must know in a given case that any necessary conditions for reliability are satisfied. He will then be in a position, in a particular case, to offer the following justification for such a spontaneous belief”: (i) I have a spontaneous belief that P (about subject-matter S) which is an instance of kind K (ii) Spontaneous beliefs about S which are instances of K are very likely to be true, if conditions C are satisfied. (iii) Conditions C are satisfied. Therefore, my belief that P is (probably) true. Is this enough to eliminate foundational or basic beliefs from Bonjour’s scheme??? How about beliefs of type P, which are about experience and which are introspectively accessible??? So, how do we answer (I), (II) and (III) 10 II. According to the CTEK, empirical beliefs are justified only in terms of relations to other beliefs and to the system of beliefs; at no point does any relation to the world come in. But this means that the alleged system of empirical knowledge is deprived of all input from the world. Surely such a self-enclosed system of beliefs cannot constitute empirical knowledge. How does CTEK allow for the possibility of input from the world into the cognitive system, a possibility which is in fact realized in our cognitive system??? I. According to the CTEK, the system of beliefs which constitutes empirical knowledge is justified solely by reference to coherence. But coherence will never suffice to pick out one system of beliefs, since there will always be many other alternative, incompatible systems of belief which are equally coherent and hence equally justified according to the CTEK. How does CTEK make it unlikely that there will, in the long run, end up being an indefinitely large number of equally coherent alternative theories of the world??? 11
