Ruth Millikan

This collection of essays serves both as an introduction to Ruth Millikan’s much-discussed volume Language, Thought, and Other Biological Categories and as an extension and application of Millikan’s central themes, especially in the philosophy of psychology. The title essay discusses meaning rationalism and argues that rationality is not in the head, indeed, that there is no legitimate interpretation under which logical possibility and necessity are known a priori. In other essays, Millikan clarifies her views on the nature of mental representation, explores whether human thought is a product of natural selection, examines the nature of behavior as studied by the behavioral sciences, and discusses the issues of individualism in psychology, psychological explanation, indexicality in thought, what knowledge is, and the realism/antirealism debate.

Philosophers and laymen alike have traditionally assumed that whether you can reason well, make valid inferences, avoid logical mistakes and so forth is entirely a matter of how well the cogs in your head are fashioned and oiled. Partner to this is the assumption that careful reflection is always the method by which we discover whether an inference or reasoning process is correct. Against this, I argue that good reasoning needs constant empirical support; conceptual clarity is not an a priori, but a deeply empirical matter. Moreover, clear thinking is possible only as embedded in a cooperative external world.

On Reading Signs; Some Differences between Us and The Others If there are certain kinds of signs that an animal cannot learn to interpret, that might be for any of a number of reasons. It might be, first, because the animal cannot discriminate the signs from one another. For example, although human babies learn to discriminate human speech sounds according to the phonological structures of their native languages very easily, it may be that few if any other animals are capable of fully grasping the phonological structures of human languages. If an animal cannot learn to interpret certain signs it might be, second, because the decoding is too difficult for it. It could be, for example, that some animals are incapable of decoding signs that exhibit syntactic embedding, or signs that are spread out over time as opposed to over space. Problems of these various kinds might be solved by using another sign system, say, gestures rather than noises, or visual icons laid out in spatial order, or by separating out embedded propositions and presenting each separately. But a more interesting reason that an animal might be incapable of understanding a sign would be that it lacked mental representations of the necessary kind. It might be incapable of representing mentally what the sign conveys. When discussing what signs animals can understand or

The positions of Brandom and Millikan are compared with respect to their common origins in the works of Wilfrid Sellars and Wittgenstein. Millikan takes more seriously the “picturing” themes from Sellars and Wittgenstein. Brandom follows Sellars more closely in deriving the normativity of language from social practice, although there are also hints of a possible derivation from evolutionary theory in Sellars. An important claim common to Brandom and Millikan is that there are no representations without function or “attitude”.
