Hayek, Popper, and the Causal Theory of the Mind

Purpose – The chapter provides an exposition both of Hayek's causal theory of the mind (especially as applied to intentionality) and of Popper's critique of causal theories, argues that Hayek fails successfully to rebut Popper's critique, and shows how the dispute between Hayek and Popper is relevant to controversies in contemporary philosophy of mind.

Methodology/approach –The chapter elucidates Hayek's ideas and Popper's by situating them within the history of the mind/body problem and comparing them to the views of contemporary philosophers like Fred Dretske, Jerry Fodor, and Hilary Putnam.

Findings – Popper's critique has yet to be answered, either by Hayek or by contemporary causal theorists.

Originality/value of the chapter –The chapter calls attention to some important but neglected ideas of Hayek and Popper and examines some of their as-yet-unpublished writings.
