Written by one of today's most creative and innovative philosophers, Ruth Garrett Millikan, this book examines basic empirical concepts; how they are acquired, how they function, and how they have been misrepresented in the traditional philosophical literature. Millikan places cognitive psychology in an evolutionary context where human cognition is assumed to be an outgrowth of primitive forms of mentality, and assumed to have 'functions' in the biological sense. Of particular interest are her discussions of the nature of abilities as different from dispositions, her detailed analysis of the psychological act of reidentifying substances, and her critique of the language of thought for mental representation. In a radical departure from current philosophical and psychological theories of concepts, this book provides the first in-depth discussion on the psychological act of reidentification.

How do frogs represent their prey? This question has been the focus of many debates among proponents of naturalistic theories of content, especially among proponents of teleosemantics. This is because alternative versions of the teleosemantic approach have different implications for the content of frog representations, and it is still controversial which of these content ascriptions (if any) is the most adequate. Theorists often appeal to intuitions here, but this is a dubious strategy. In this paper, I suggest an alternative, empirical test for theories of content. I propose that we should examine whether a theory generates content ascriptions that fit with our best scientific explanations of animal behavior. I then focus on the most prominent version of teleosemantics, Ruth Millikan’s consumer-oriented approach, and argue that it fails the empirical test in the frog case, since it yields a content ascription that (i) does not include properties that should be included (namely, being small, dark and moving ) and (ii) includes a property that should not be included (namely, being frog food ). This is an important result in itself, but it also demonstrates by way of example how progress can be made in the complex debate about theories of content.

I pose the following dilemma for Millikan's teleological theory of mental content. There is only one way that her theory can avoid Gauker's [(1995) Review of Millikan's White queen psychology and other essays for Alice, Philosophical Psychology, 8, 305-309] charge that it relies on an unexplained notion of mapping or isomorphism between mental state and world. Mental content must be explained in terms of the mapping relation that is required for mental state producing and consuming mechanisms to perform their biologically proper functions, i.e. producing mental states that are consumed in systematically adaptive practical inferences. However, this proposal leads to unacceptably counterintuitive ascriptions of content to mythological beliefs and related desires: such beliefs and desires must "map onto" environmental states that make them adaptive, not onto the mythological states of affairs that (would) make them true or fulfilled. I conclude by discussing the merits and drawbacks of a potential solution to this problem: the view that the contents of mythological beliefs and desires are determined by the non-mythological concepts out of which they are constructed, rather than by the environmental states that make them adaptive. The affinities of this proposal with Pascal Boyer's recent theory of mythological concepts [(2001) Religion explained, New York: Basic Books] are also discussed.

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function to explain what it is for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

Ruth Millikan and others advocate theories which attempt to naturalize wide mental content (e.g. beliefs.
