Skinner, Department of Psychology and Social Relations, Harvard University, Cambridge, Mass. 02138 Original Abstract: Each of us is uniquely subject to certain kinds of stimulation from a small part of the universe within our skins. Mentalistic psychologies insist that other kinds of events, lacking the physical dimensions of stimuli, are accessible to the owner of the skin within which they occur. One solution often regarded as behavioristic, granting the distinction between public and private events and ruling the latter out of consideration, has not been successful. A science of behavior must face the problem of privacy by dealing with events within the skin in their relation to behavior, without assuming they have a special nature or must be known in a special way. The search for copies of the world within the body (e.g. the sensations and images of conscious content) has also had discouraging results. The organism does not create duplicates: Its seeing, hearing, smelling, and so on are forms of action rather than of reproduction. Seeing does not imply something seen. We know that when we dream of wolves, no wolves are actually there; it is harder to understand that not even representations of wolves are there. Mentalistic formulations create mental way stations. Where experimental analyses examine the effects of variables on behavior, mentalistic psychologies deal first with their effects on inferred entities such as feelings or expectations and then with the effects of these entities on behavior. Mental states thus seem to bridge gaps between dependent and independent variables, and mentalistic interpretations are particularly attractive when these are separated by long time periods. The practice confuses the order of events and leads to unfinished causal accounts.

Furedya and Diane M. Rileyb a Department of Psychology, University of Toronto, Ont., Canada, M5S 1A1 and bAddiction Research Foundation, Toronto, On, Canada M5S 2S1 Behaviorism, like most influential “isms,” requires qualification by proper names to differentiate between its many forms. The behaviorism whose 50th birthday was celebrated in the target article is obviously different from the approaches of other behaviorists such as Hull (who used beneath-the-skin, internal hypothetical explanatory constructs) and Tolman (who was both mentalistic and teleological in his approach). Watsonian-Skinnerian behaviorism is radical in its rejection of many of the assumptions of approaches such as those of Hull and Tolman. That is, radical behaviorism not only rejects teleological explanations, it also rejects "internal" hypothetical constructs, especially mentalism. However, approaches that seek to cleanse us root and branch tend to offer judgments that are undifferentiated in that there is no attention paid to some critical distinctions. Another feature of such approaches is that the flaws that appear writ large in the opposition are ignored in the favored approach; this selectivity results in (in reference to the biblical phrase) “mote-beam” percepts. We briefly discuss two undifferentiated distinctions. The first is between teleological and mechanistic mentalism, the second between knowledge and ability. Finally, a case of "motebeam" perception of explanatory circularity is presented. Regarding mentalism, it is true that in an approach such as that of Tolman, there was a link between teleology (the inclusion of purpose as an intervening variable) and mental events (the inclusion of the concept of the cognitive map as an intervening variable). The link between teleology and mentalism, however, is historical rather than logical. Instances of mechanistic (ateleological) mentalist positions are available even from Tolman's era (see, e.g., the attack on teleology in the concept of homeostasis by Maze 1953). Moreover, many current cognitive experimental psychologists are not teleological inasmuch as their basic analogy - the computer - does not involve purposes but only mechanistically determined programs. Finally, specific issues under current investigation involve Commentary /Skinner: Behaviorism at fifty examining a form of cognitivism that is not teleological but mechanistic. For example, the claim that awareness of the CS-US relationship is necessary, but not sufficient, for autonomic conditioning (see, e.g., Dawson 1973; Dawson & Furedy 1976; Furedy 1973) is a position that involves no talk of purposes whatsoever. Skinner's "Behaviorism-50" does not appear to make this important distinction between teleology and mentalism. For example, in the discussion of "mental way stations," the account of the student explanations or "responses" lumps together the mechanistic and teleological forms of mentalism, in that it does not differentiate between explanations in terms of the organism's mechanistic knowledge and its purposive intentions. It bears emphasis that, especially because Skinner's main charge against mentalism is that its explanatory constructs are circular, the distinction between teleological and mechanistic mentalism is of more than mere scholastic significance. Teleological concepts have a built-in circularity as explanations, because any contrary-to-prediction outcome can be explained away as a result of a change in purpose of the (implicit) agent (see, e.g., Maze 1953). This is not to imply that mentalism when used in explanations is without problems numerous difficulties arise over issues such as the nature of representation. However, these problems are not as intractable as those of teleological explanations. The problem with ateleological, mentalist explanations is that they appear to be less parsimonious than those of radical behaviorism. However, to the extent that one seeks to account for what complexly occurs, it is necessary to recognize that the feeling of striving appears to be a real feature of human mental activity. This feature then requires explanation, rather than excision by Ockham's razor. And the ateleological mentalist would argue that such explanation has the virtue of providing some account of events that do, in fact, occur. By analogy, and related to Skinner's discussion of representation, it may seem more parsimonious to explain moving pictures in terms only of the events that are actually visible on the screen, and to dismiss references to movie projectors as constituting unnecessary mysticism. However, in terms of the way things, in their complexity, are, accounts of the process that include reference to movie projectors are THE BEHAVIORAL AND BRAIN SCIENCES (1984) 7:4 more appropriate, because they are more accurate. Such accounts are more complex than those of the radical-behaviorist form, and may require reference to "a new mechanism," but this is because the phenomena require it, and not just because theorists do. The other distinction that the target article appears to neglect is that between knowing propositions and having the ability to perform responses, or knowing that and "knowing" (in quotes, because, strictly speaking, only propositions can be known) how (Ryle 1949). The running together of this distinction occurs most obviously in Skinner's discussion of the acrobat. In this account, it is suggested that not only the performance (handsprings) but also the account of that performance (propositions concerning the important actions needed to produce successful performance) are all responses, the latter sort of expressions being “verbal responses” which “arise from contingencies . . . arranged by a verbal community.” However, on this account, we would not be able to discriminate between so-called verbal responses that state false propositions (i.e. a champion hand-springer who, however, is a poor coach inasmuch as he is cognitively unaware of the nature of good handspringing) and those that state true ones (i.e. one who can cognitively teach as well as produce correct performance responses). The reason this discrimination cannot be made is because responses are not prepositional, being expressions that it would be a “category mistake” (Ryle 1949) to speak of as either true or false (see also Furedy & Riley 1982; Furedy, Riley & Fredrikson 1983). In Ryle's terms, knowing that and knowing how are different processes, and neither can be reduced to the other without a serious loss of the ability to make factually, and therefore scientifically, relevant distinctions. Concerning the “mote-beam” perception of circularity in explanatory concepts, we have already noted that "Behaviorism-50" roundly condemns positions opposed to radical, Watsonian-Skinnerian behaviorism for such concepts, and therefore charges their theories with being untestable. "Mentalism," with its “way stations,” is portrayed as the main villain in the piece, but behaviorisms like those of Hull would also be suspect, because they make use of internal, within-the-skin constructs instead of sticking to the presumably noncircular external, environmental concepts like various “schedules of reinforcement,” the "verbal environment," and past reinforcement history. Commentary /Skinner: Behaviorism at fifty Because in the target article the focus is on mentalism rather than nonradical behaviorist systems, we restrict the discussion to the comparison between mentalism and radical behaviorism. The circularity in mentalism is less problematic or more mote-like than Skinner would have it, because, as indicated above, it is only in the teleological form of mentalism that circularity is inherent in the explanations, and the theory is hence untestable. The beamlike perception, we suggest, is due to a commonly made error of not recognizing the teleologicalmechanistic distinction (discussed above) in the unfavored mentalist camp and that at least some mentalist accounts are not teleological but mechanistic. On the other hand, radical behaviorists have continued to appear quite insensitive to the beam of circularity in their own eyes when it comes to explanations. The point is that, contrary to certain metaphysical prejudices, circularity is determined not by the "stuff" of which the explanatory concept is made, but by the extent to which theorists specify their explanatory constructs so that they can be assessed independently of the effects they are supposed to explain. So the gravity and libido constructs are equally intangible, but gravity theory is more testable than the Freudian libido theory. The former theory (asserting that all physical objects are influenced by gravity) is vulnerable to specifiable, disconfirming events such as hovering 10 feet above the ground without any mechanical aids in a way that the latter theory (asserting that all human behavior is influenced by the sex drive) is not, because there is no specifiable behavior that would, if it did occur, falsify the libido hypothesis. This is because Freudian theory has constructs like "repression" in it that are not specifiable independently of the (apparently asexual) behavior that they, in conjunction with the libido, are taken to explain. However, the environmental, “tangible” constructs used in “Behaviorism-50” appear to be no more adequately specified than the libido and repression. What behavioral outcome would it take to produce a disconfirmation of the explanatory concept of “various reinforcement schedules”? Again, is there any conceivable verbal utterance that would, if it did occur, require Skinner to give up the radically environmentalist explanation that the utterance was caused by “the verbal community”? To the extent that no such outcomes (even were they to be hypothetical rather than actual) can be specified, it would seem that the circularity in the eye of radical behaviorism's modes of explanation is, indeed, beamlike in proportions. In discussing the problem of circularity, we have deliberately used the scientifically low-status Freudian system. Our reason for doing so is to reinforce our contention (not argued for in detail here) that the problem of explanatory circularity must be dealt with by adequately specifying the explanatory constructs, rather than by thinking that a move from internal to external referents is sufficient for the task. Author’s Reply B. F. Skinner Department of Psychology and Social Relations, Harvard University, Cambridge, Mass. 02138 The teleological side of Furedy & Riley's commentary could have found a more appropriate place in “Consequences.” What they call mechanism seems to be the current state of the organism described in the language of physics and biology. The organism behaves as it does because of its present state. What they find missing is intentionality. Others might have spoken of purpose, expectation, and anticipation. These are not aspects of the present state of the organism but of its selective phylogenic and ontogenic history. Behavior seems to be directed toward future consequences, but only because it is a product of past consequences. The hand is not made for the purpose of holding things; it has evolved in a given way because it has held things well. A boy does not go to the cookie jar with the purpose of getting a cookie; he goes because he has got cookies in the past. (If he goes because he has been told that there are cookies there, a different set of selective contingencies must be invoked, as discussed in “Problem Solving.” The contingencies will be much more complex but nevertheless only contingencies.) In common use, knowledge refers to a personal possession resulting from exposure to environmental contingencies. To use it only for propositions is in violation of tradition and common sense. Most people would say that a boy who learns to ride a bicycle well knows how to ride. But does he possess knowledge or has his THE BEHAVIORAL AND BRAIN SCIENCES (1984) 7:4 Commentary /Skinner: Behaviorism at fifty behavior simply been well shaped by the contingencies maintained by bicycle? When a hungry rat presses a lever, receives food, and as a result presses the lever more rapidly, many cognitive psychologists say that it has "learned (and hence knows) that pressing the lever brings food." "Pressing the lever brings food" is a description of the contingencies. Somehow or other a version is said to pass into the head of the rat. A human subject could, of course, describe the contingencies and know them in the sense in which adperson knows a poem. Has anyone shown that there is an advantage in creating these internal simulacra of environmental contingencies? We "impart knowledge" through environmental means. We test for its existence through environmental measures. We determine its essential properties by examining what the supposed possessor does. If there is any circularity it is in the eye of the cognitive psychologist, as a hypothetical internal knowledge inferred from behavior is used to explain the behavior. References Dawson, M. E.
