This paper traces the application of information theory to philosophical problems of mind and meaning from the earliest days of the creation of the mathematical theory of communication. The use of information theory to understand purposive behavior, learning, pattern recognition, and more marked the beginning of the naturalization of mind and meaning. From the inception of information theory, Wiener, Turing, and others began trying to show how to make a mind from informational and computational materials. Over the last 50 years, (...) many philosophers saw different aspects of the naturalization of the mind, though few saw at once all of the pieces of the puzzle that we now know. Starting with Norbert Wiener himself, philosophers and information theorists used concepts from information theory to understand cognition. This paper provides a window on the historical sequence of contributions made to the overall project of naturalizing the mind by philosophers from Shannon, Wiener, and MacKay, to Dennett, Sayre, Dretske, Fodor, and Perry, among others. At some time between 1928 and 1948, American engineers and mathematicians began to talk about `Theory of Information' and `Information Theory,' understanding by these terms approximately and vaguely a theory for which Hartley's `amount of information' is a basic concept. I have been unable to find out when and by whom these names were first used. Hartley himself does not use them nor does he employ the term `Theory of Transmission of Information,' from which the two other shorter terms presumably were derived. It seems that Norbert Wiener and Claude Shannon were using them in the Mid-Forties. (shrink)
People intend to do things, try to do things, and do things. Do they also will to do things? More precisely, if people will to do things and their willing bears upon what they do, is willing, or volition, something distinct from intending and trying? This question is central to the intention/volition debate, a debate about the ingredients of the best theory of the nature and explanation of human action. A variety of competing conceptions of volition, intention, and trying have (...) been advanced in the literature; it would be impossible to examine each thoroughly in a single paper. We can show, however, that the major functional roles ascribed to volition are nicely filled by a triad composed of intention, trying, and information feedback. Sections I and II below develop an account of the connection between intention and trying. Section III examines leading arguments for the existence of volitions and decomposes volitions into members of the triad just identified. (shrink)
A great deal of attention has been paid in recent years to the function- al roles of intentions in intentional action. In this paper we sketch and defend a position on this issue while attacking a provocative alternative. Our position has its roots in a cybernetic theory of purposive behavior and is only part of the larger task of understanding all goal-directed behavior. Indeed, a unified model of goal-directed behavior, with appropriate modifications for different types of systems, is a long-range (...) ambition. (shrink)
In a recent paper, Al Mele (2003) suggests that the Simple View of intentional action is “fiction” because it is “wholly unconstrained” by a widely shared (folk) concept of intentional action. The Simple View (Adams, 1986, McCann, 1986) states that an action is intentional only if intended. As evidence that the Simple View is not in accord with the folk notion of intentional action, Mele appeals to recent surveys of folk judgments by Joshua Knobe (2003, 2004a, 2004b). Knobe’s surveys appear (...) to show that the folk judge unintended but known side effects of actions to be performed intentionally. In this paper we will reject Mele’s suggestion that the Simple View is “fiction.” We will also discuss the relationship between surveys and philosophical theories, and the abilities of surveys to access folk core concepts. We will argue that considerations of both fail to support Mele’s suggestion. (shrink)
In ‘‘The Myth of Original Intentionality,’’ Daniel Dennett appears to want to argue for four claims involving the familiar distinction between original (or underived) and derived intentionality.
The analysis of function-ascribing statements, such as “the function of x is y”, is proving to be a difficult matter. It is difficult because we are only beginning to see the complexity which is involved in ascribing functions. The process of discovery has been slow and tedious, with each newly constructed analysis of the meaning of functional ascriptions yielding insights into the structure of functional analysis and functional explanation. However, as each analysis is, in turn, dismantled, we seem to see (...) our insights slip away. In the wake of each exchange, a new member is added to the list of desiderata for an analysis of function-ascribing statements. Thus, the matter of finding a proper analysis of function attributions becomes more and more complex. (shrink)
InPsychosemantics Jerry Fodor offered a list of sufficient conditions for a symbol “X” to mean something X. The conditions are designed to reduce meaning to purely non-intentional natural relations. They are also designed to solve what Fodor has dubbed the “disjunction problem”. More recently, inA Theory of Content and Other Essays, Fodor has modified his list of sufficient conditions for naturalized meaning in light of objections to his earlier list. We look at his new set of conditions and give his (...) motivation for them-tracing them to problems in the literature. Then we argue that Fodor's conditions still do not work. They are open to objections of two different varieties: they are too strong and too weak. We develop these objections and indicate why Fodor's new, improved list of conditions still do not work to naturalize meaning. (shrink)
Assume that epistemic justification has a cognitive function and that a belief's being justified is not just its being caused by the appropriate information (for this property of the belief may be cognitively impenetrable). What is the function of epistemic justification? it cannot be to actualize knowledge-The belief's being caused by appropriate information alone does that! so what is its function? I suggest it is to cause us to believe and/or take action.
There are both externalist and internalist theories of the phenomenal content of conscious experiences. Externalists like Dretske and Tye treat the phenomenal content of conscious states as representations of external properties. Internalists think that phenomenal conscious states are reducible to electrochemical states of the brain in the style of the type-type identity theory. In this paper, we side with the representationalists and visit a dispute between them over the test case of Swampman. Does Swampman have conscious phenomenal states or not? (...) Dretske and Tye disagree on this issue. We try to settle the dispute in favor of Dretske's theory. (shrink)
Sue knows that, unaided, she cannot lift the 1,000 pound weight, but surely she can try. Can she not? For even if she believes it is impossible to succeed in lifting the weight, trying to lift the weight need not involve success. So surely, it would seem that nothing could be easier than for Sue to give lifting the weight a try. In this paper, I agrue that, appearances aside, it is not possible for someone to try to do what (...) that person believes to be impossible. So, on this view, perhaps surprisingly, not only would it be impossible for Sue to lift the weight, but it would be impossible for her to try (as long as she believed her lifting it to be impossible). I defend this view in the context of a package of related claims and a functional accoung of trying and intentional action. (shrink)
Is intentionally doing A linked to the intention to do A? Knobe and Burra believe that the link between the English words ‘intention’ and ‘intentional’ may mislead philosophers and cognitive scientists to falsely believe that intentionally doing an action A requires one to have the intention to do A. Knobe and Burra believe that data from other languages..
What we do, intentionally, depends upon the intentional contents of our thoughts. For about ten years Fodor has argued that intentional behavior causally depends upon the narrow intentional content of thoughts (not broad). His main reason is a causal powers argument—brains of individuals A and B may differ in broad content, but, if A and B are neurophysically identical, their thoughts cannot differ in causal power, despite differences in broad content. Recently Fodor (Fodor, 1991) presents a new 'modal' version of (...) this causal powers argument. I argue that Fodor's argument (in old or new dress) is a non sequitur. It neither establishes the existence of narrow content nor the need for a content other than broad content to explain intentional behavior. (shrink)
In “A Theory of Content, 11: The Theory,” Jerry Fodor presents two reasons why his asymmetric causal dependency theory does not lead to the conclusion that syntactic items “X” mean proximal sensory stimulations, rather than distal environmental objects. Here we challenge Fodor’s reasoning.
In an earlier paper, we argued that Fodorian Semantics has serious difficulties. However, we suggested possible ways that one might attempt to fix this. Ted Warfield suggests that our arguments can be deflected and he does this by making the very moves that we suggested. In our current paper, we respond to Warfield's attempts to revise and defend Fodorian Semantics against our arguments that such a semantic theory is both too strong and too weak. To get around our objections, Warfield (...) proposes a modified reading of one of Fodor's conditions and proposes adding a new condition to the theory. We show that neither the modified reading nor the additional condition saves the asymmetric causal dependency approach to naturalized semantics. (shrink)
What is the relationship between trying, desire, and desiring to try? Is it necessary to desire to do something in order to try to do it? Must Dave desire to quit smoking in order to try to quit? I shall defend the view that desiring to do A is necessary for trying to do A. First, Dave needs motivation to quit smoking and motivation comes in the form of desire. So it seems straightforward that when one tries to do something (...) A, one’s desire to do that thing A is one’s motivation. Second, when Dave throws out a pack of cigarettes, this may or may not be part of an attempt to quit smoking. It may be a political protest against R.J.R. Nabisco. Dave’s throwing out the cigarettes only counts as part of his attempt to quit smoking, if it is done for the right reason, out of the right motivation. Again, the right motivation seems to be the desire to quit smoking. Thus, the desire to do A appears to play important roles in the attempt to do A. At the very least, it helps to motivate, guide, and constitute the attempt as the attempt to do A. It is because Dave wants to quit smoking that his throwing out his cigarettes counts as part of his attempt to quit smoking, not as a political protest. (shrink)
1. Do models formulated in programming languages use explicit rules where connectionist models do not? 2. Are rules as found in programming languages hard, precise, and exceptionless, where connectionist rules are not? 3. Do connectionist models use rules operating on distributed representations where models formulated in programming languages do not? 4. Do connectionist models fail to use structure sensitive rules of the sort found in "classical" computer architectures? In this chapter we argue that the answer to each of these questions (...) is negative. (shrink)
This is a plausible reading of what Clark and Chalmers had in mind at the time, but it is not the radical claim at stake in the extended cognition debate.[1] It is a familiar functionalist view of cognition and the mind that it can be realized in a wide range of distinct material bases. Thus, for many species of functionalism about cognition and the mind, it follows that they can be realized in extracranial substrates.[2] And, in truth, even some non-functionalist (...) views of cognition apparently allow for the possibility that cognition extends into the external world.[3] So, the (logical, conceptual, or nomological) possibility of extended cognition seems to us not the kind of radical view the advocates of this view have often implied. This is not, of course, to assess or pass judgment on the truth of these possibilities; it is only to note that they are not what most agitates people about the hypothesis of extended cognition. Framing the radical extended cognition hypothesis is a more delicate matter than framing the modal extended cognition hypothesis, but something like the following is in the ballpark. The radical extended cognition hypothesis maintains that, in many mundane cases of tool use, human cognitive processes extend into the tools. The principal reason this hypothesis is so delicate is that there remains much room for dispute about what constitutes a. (shrink)
In the etiology of teleological functions, what role can be played by accidental occurrences? Douglas Ehring's essay “Accidental Functions” constructs a theory of ideological functions which makes it possible for objects to have functions even when their causal origins are due entirely to accident—be they natural functions or artifact functions. Ehring constructs this view on the basis of a set of putative counterexamples aimed largely at the theories of Enc and Adams. Both of these theories block the attribution of ideological (...) function to structures with entirely accidental causal histories—accidental in originandin the way their effects are causally sustained.

This paper defends a direct reference view of empty names, saying that empty names literally have no meaning and cannot be used to express truths. However, all names, including empty names, are associated with accompanying descriptions that are implicated in pragmatically imparted truths. A sentence such as “Vulcan doesn’t exist” pragmatically imparts that there is no tenth planet. This view is defended against objections.
Reliabilism has received its share of bad press of late both as a theory of knowledge and as a theory of epistemic justification. We believe its credibility as a theory of knowledge may have been unjustly tarnished and we plan to defend it. However, we hasten to add that we shall defend reliabilism from attack only upon its credentials as a basis for a theory of knowledge. We shall not defend it as a theory of epistemic justification, although we do (...) believe that the latter is a worthy pursuit. (shrink)
In this introduction to philosophy, philosophers in their areas of specialization have produced essays written specifically for the novice. The collection includes traditional topics such as logic, metaphysics, epistemology, ethics, political philosophy, aesthetics, philosophy of religion , personal identity, and contemporary topics such as philosophy of mind and cognitive science.
I am pleased to be able to respond to Al Mele’s reply to my paper on trying and desire. My remarks will bebriet.First, it is not thesis T that I find objectionable. It may be possible for me to want TO TRY to quit smoking, while currently not wanting TO QUIT smoking. I may want to try because I want to ACQUIRE the desire to quit, since people persist in nagging me to quit. So I accept thesis T because it (...) is not the issue. The issue is whether one can PERFORM THE ATTEMPT to quit smoking WHILE one lacks the desire to quit smoking. THAT is what I find objectionable and impossible. Mele accepts that it is possible. I believe such an attempt to be merely ‘going through the motions’ in bad faith and not a genuine attempt at all. I believe this for the controltheoretic reasons that I outlined in my original paper and elsewhere. (shrink)
