Fred Dretske?s (1988) account of the causal role of intentional mental states was widely criticized for missing the target: he explained why a type of intentional state causes the type of bodily motion it does rather than some other type, when what we wanted was an account of how the intentional properties of these states play a causal role in each singular causal relation with a token bodily motion. I argue that the non-reductive metaphysics that Dretske defends for his account of behavior can be extended to the case of intentional states, and that this extension provides a way to show how intentional properties can play the causal role that we wanted explained.

The apparent incompatibility of mental states with physical explanations has long been a concern of philosophers of psychology. This incompatibility is thought to arise from the intentionality of mental states. But, Brentano notwithstanding, intentionality is an ordinary feature of higher order behavior patterns in the classical literature of ethology.

States that are about things are intentional, that is, they have content. The precise nature of intentional states is a matter of dispute.What makes some states, but not others, intentional? Of those states that are intentional, what makes them about what they are about as opposed to something else, i.e. what gives them their specific content?

What is the relationship between phenomenology and intentionality? A common picture in recent philosophy of mind has been that the phenomenal aspects and the intentional aspects of mentality are independent of one another. According to this view, the phenomenal character of certain mental states or processes”states for which there is "something it is like" to undergo them—is not intentional. Examples that are typically given of states with inherent phenomenal character are sensations, such as pains, itches, and color sensations. This view also asserts, on the other hand, that the intentionality of certain mental states and processes their "being about something" is not phenomenal. Beliefs and desires are the paradigm cases of intentional mental states. Although they are intentionally directed (i.e., they have aboutness) these mental states are not inherently phenomenal. There is nothing that it is like to be in such a state by virtue of which it is directed toward what it is about. We will call this picture separatism, because it treats phenomenal aspects of mentality and intentional aspects of mentality as mutually independent, and thus separable. Although there may be complex states that are both phenomenal and intentional, their phenomenal aspects and their intentional aspects are separable. Many philosophers who hold this picture have thought that these two aspects of mentality lead to quite different sorts of problems with respect to the project of “naturalizing the mental.†Proponents of separatism often hold that while the problem of naturalizing phenomenology poses great difficulties, the problem of naturalizing intentionality is much..

Intentionality is the mind’s capacity to direct itself on things. Mental states like thoughts, beliefs, desires, hopes (and others) exhibit intentionality in the sense that they are always directed on, or at, something: if you hope, believe or desire, you must hope, believe or desire something. Hope, belief, desire and any other mental state which is directed at something, are known as intentional states. Intentionality in this sense has only a peripheral connection to the ordinary ideas of intention and intending. An intention to do something is an intentional state, since one cannot intend without intending something; but intentions are only one of many kinds of intentional mental states. The terminology of intentionality derives from the scholastic philosophy of the Middle Ages, and was revived by Brentano in 1874. Brentano characterized intentionality in terms of the mind’s direction upon an object, and emphasized that the object need not exist. He also claimed that it is the intentionality of mental phenomena that distinguishes them from physical phenomena. These ideas of Brentano’s provide the background to twentieth-century discussions of intentionality, in both the phenomenological and analytic traditions. Among these discussions, we can distinguish two general projects. The first is to characterize the essential features of intentionality. For example, is intentionality a relation? If it is, what does it relate, if the object of an intentional state need not exist in order to be thought about? The second is to explain how intentionality can occur in the natural world. How can..

I question Brentano's thesis that all and only mental phenomena are intentional. The common gloss on intentionality in terms of directedness does not justify the claim that intentionality is sufficient for mentality. One response to this problem is to lay down further requirements for intentionality. For example, it may be said that we have intentionality only where we have such phenomena as failure of substitution or existential presupposition. I consider a variety of such requirements for intentionality. I argue they either fail to exclude all non-mental phenomena or are so demanding that they ground new, serious challenges to the claim that qualitative states of mind are intentional.

Representationalists argue that phenomenal states are intentional states of a special kind. This paper offers an account of the kind of intentional state phenomenal states are: I argue that they are underived intentional states. This account of phenomenal states is equivalent to two theses: first, all possible phenomenal states are underived intentional states; second, all possible underived intentional states are phenomenal states. I clarify these claims and argue for each of them. I also address objections which touch on a range of topics, including meaning holism and concept empiricism. I conclude with a brief discussion of the consequences of the proposed view for the project of naturalizing consciousness.

Exploring intentionality from an externalist per- spective, I distinguish three kinds of intentionality in the case of seeing, which I call transparent, translucent, and opaque respec- tively. I then extend the distinction from seeing to knowing, and then to believing. Having explicated the three-fold distinction, I then critically explore some important consequences that follow from granting that (i) there are transparent and translucent in- tentional states and (ii) these intentional states are mental states. These consequences include: ?rst, that existential opacity is neither the mark of intentionality nor of the mental; second, that Sellars has not shown that all intentionality is non-relational; third, that a key Quinean argument for semantic indeterminacy rests on a false premise; fourth, that perceptual experience is intentional on Alston.
