The object of this paper is to discuss several issues raised by Fred Dretske’s account of the causal efficacy of content, as given in his book Explaining Behavior. To warrant the causal efficacy of folk-psychological properties while keeping attached to a naturalistic framework, Fred Dretske proposes that these properties are causes of a peculiar type, what he calls structuring causes. Structuring causes are not postulated ad hoc, to somehow account for the causal efficacy of content. Dretske claims (...) that we independently need this dualism of causes to make sense of some of our (not necessarily involving mental states) causal explanations. Even if this variety of dualism is not untenable from a openly-minded physicalistic viewpoint, it seems for several reasons preferable to establish that content properties are causally efficacious in the same sense that physical properties are. The main point I will try to make in this paper is a metaphysical one, namely, that Drestke’s structuring causes are causes of a more ordinary kind. I will try to show that we can make sense of the phenomena that structuring causes are introduced to account for in more conservative terms, having only recourse to the material we must anyway posit to understand ordinary causal explanations.

Dretske’s Naturalizing the Mind sets out the case for holding that mental states in general are natural representers of reality. Mental states have functions; for many states the function is to indicate what is going on in the world. Among such indicator states are beliefs. The content of these states is given by what they are supposed to represent. So if a state is supposed to indicate that it’s dark, then “it’s dark” is the content of the state. Thus (...) we can characterize how the organism takes things to be, its subjectivity, by noting first what physical (neural) state it is in, and second what the biological indicator function of that state is. Thus the mind and meaning are naturalized. (shrink)

In his recent book, Explaining Behavior: Reasons in a World of Causes, Fred Dretske develops at length a conception of behavior as part of an ingenious attempt to display the causal relevance of intentional states, qua intentional, to behavior. So-called folk-psychological explanations of intentional human behavior accord central explanatory roles to beliefs, desires, reasons, intentions, and the like. But how, Dretske asks, do the distinctively psychological features of such items figure in the etiology of behavior - how, for (...) example, do reasons qua reasons contribute to human behavior? My primary concern here, however, is with a significant portion of the ground work that Dretske lays for the answer -specifically, his conception of behavior. (shrink)

In this paper I discuss Fred Dretske's account of knowledge critically, and try to bring out how his account of informational content leads to cases of extreme epistemic good luck in his treatment of knowledge. My main interest, however, is to establish that the cases of epistemic luck arise because Dretske's account of knowledge in a fundamental way fails to take into account the role our actual recognitional capacities and powers of discrimination play in perceptually based knowledge. This (...) result is, I believe, new. The paper has three sections. In Section 1 I give a short exposition of Dretske's theory, and make some necessary qualifications about how it is to be understood. In Section 2 I discuss in greater detail how the theory actually works, and provide some examples I think are very troublesome for Dretske. In Section 3 I argue that these cases establish my main claim. I also show that there are cases of epistemic bad luck due to Dretske's account of how information causes belief. (shrink)

Contrary to Dretske's view, treating actions as causal complexes wherein inner states produce external results does not permit us to claim that even if their components are caused, the actions are not. What triggers the initial element of a causal sequence causes the sequence itself, so whatever might cause the relevant inner state would also cause the action. Dretske's claim that the failure of my agency to extend to the results of actions I induce in others is owing (...) to the "sensitivity" of those results' causal antecedents is also mistaken. Such sensitivity attends the results of my own actions without undoing my agency. (shrink)

In a recent article [4], Fred I. Dretske has proposed a new analysis of natural laws. Dretske rejects the more or less standard view which says that laws are universal truths with a special function or status in science. As an alternative account, he suggests that laws are expressed by singular statements describing the relationship between universal properties and magnitudes: the statement It is a law that F's are G's3.is to be analysed as F-ness ↦ G-ness.I shall argue, (...) however, that Dretske's reasons for rejecting the standard account are not conclusive. Moreover, his own proposal seems to be either inadequate or reducible to that version of the standard account which takes laws to be nomically necessary generalizations. (shrink)

Many theorists in epistemology and mind accept externalism with respect to content—namely, the claim that the conditions that individuate mental content are external to the occurrence of that content as a mental fact. Whatever it is that distinguishes a pain in the knee from a pain in the toe—or, alternatively, whatever it is that makes it possible for the subject to discriminate this pain as a pain in the knee from that pain as a pain in the toe—are factors and (...) conditions located in the physical and external world. This much externalism seems to be required even if one is a thoroughly entrenched mentalist. This “content externalism” is captured, fairly effectively, by the more traditional distinction between concepts and percepts. What is then asserted by the mentalist is that concepts have their source or origin in the external world, but the perceptual content does not. Perceptual content can be identified in different ways which are: the view that identifies the distinguishing feature of the perceptual with qualia, a position not far removed from the Lockean distinction between Primary and Secondary qualities; or, the perceptual might also be characterized in terms of representationalism, where qualia are an essential part of the representational medium, but where the representational medium contains conceptual content as well. In either case, the perceptual is Type and/or Token distinct from whatever is the external physical conditions or states of affairs causally responsible for the occurrence of either the conceptual content or the perceptual content. An argument for the claim that percepts are essential and necessary is that, without such percepts, there can be no experience. It is doubtful. (shrink)

First, I briefly characterize Dretske’s particular naturalization project, emphasizing his naturalistic reconstruction of the notion of representation. Second, I note some apparent similarities between his notion of representation and Husserl’s notion of intentionality, but I find even more important differences. Whereas Husserl takes intentionality to be an intrinsic, phenomenological feature of thought and experience, Dretske advocates an “externalist” account of mental representation. Third, I consider Dretske’s treatment of qualia, because he takes it to show that his representational (...) account of mind succeeds in naturalizing even the “subjective” features of experience. I claim that Dretske's argument for his account of qualia turns on an ambiguous characterization of qualia. I conclude that he succeeds in naturalizing qualia only if qualia are understood as nonphenomenological features of experience and that he therefore has less to say than he thinks about the subjective life of beings such as us.

When a belief is cited as part of the explanation of an agent’s behaviour, it seems that the belief is explanatorily relevant in virtue of its content. In his Explaining Behavior, Dretske presents an account of belief, content, and explanation according to which this can be so. I supply some examples of beliefs whose explanatory relevance in virtue of content apparently cannot be accounted for in the Dretskean way. After considering some possible responses to this challenge, I end by (...) discussing how serious these counterexamples are for Dretske’s account. (shrink)

In his Explaining Behavior, Fred Dretske uses a reliabilist theory of representation to try to vindicate the use of intentional explanation for behaviour against latter-day elitninativism. Although Dretske's indicator semantics turns on the notion of function, he himself never explicitly defines what function means. Dretske's reticence in discussing function may ultimately be an error, for, as I argue, his implicit understanding of what a function amounts to does not fit with data from op rant conditioning. Still, this (...) need not be a deep flaw in Dretske and I offer one way in which we may patch up the notion of function via the changes known to occur with learning in the brain. Ultimately, I conclude that the only facts needed to explain behaviour are (1) the conditions in the world that are paired with neuronal circuit activation (as picked out by goals in some circumstances); and (2) what motor output that condition triggers.

In his recent work, Dretske offers a new account of what it is for a mental state, in particular, a sensory experience, to be conscious. According to Dretske’sproposal, subject S’s experience of object O is conscious if and only if it makes S aware of O. This proposal is argued to be open to only two serious interpretations. The first takes it to mean that S’s experience of O is conscious if and only if it constitutes S’s awareness (...) of O, whereas the second takes it to mean that S’s experience of O is conscious if and only if it causes S’s awareness of O. It is argued that neither is a plausible way to understand the nature of state consciousness, because the constitutive interpretation implausibly denies the existence of unconscious veridical experiences, whereas the causal interpretation implausibly casts S’s veridical experience of O, rather than O or a certain external event involving O, as the relevant cause of S’s awareness of O.

This collection of essays by eminent philosopher Fred Dretske brings together work on the theory of knowledge and philosophy of mind spanning thirty years. The two areas combine to lay the groundwork for a naturalistic philosophy of mind. The fifteen essays focus on perception, knowledge, and consciousness. Together, they show the interconnectedness of Dretske's work in epistemology and his more contemporary ideas on philosophy of mind, shedding light on the links which can be made between the two. The (...) first section of the book argues the point that knowledge consists of beliefs with the right objective connection to facts; two essays discuss this conception of knowledge's implications for naturalism. The next section articulates a view of perception, attempting to distinguish conceptual states from phenomenal states. A naturalized philosophy of mind, and thus a naturalized epistemology, is articulated in the third section. This collection will be a valuable resource for a wide range of philosophers and their students, and will also be of interest to cognitive scientists, psychologists, and philosophers of biology.

I argue that Fred Dretske's account of the causal relevance of content only works if another account works better, that put forward by Gabriel Segal and Elliot Sober. Dretske needs to appeal to it to deal with two problems he faces: one arising because he accepts that the mere association between indicators and indicated is causally relevant to the recruitment of indicators in causing behaviour, the other from the need to explain how a present token of a certain (...) type of content is causally relevant. For this and other reasons their approach has clear advantages over Dretske's. (shrink)
