Prinz (Perceptual the Mind: Concepts and Their Perceptual Basis, MIT Press, 2002) presents a new species of concept empiricism, under which concepts are off-line long-term memory networks of representations that are ‘copies’ of perceptual representations – proxytypes. An apparent obstacle to any such empiricism is the prevailing nativism of generative linguistics. The paper critically assesses Prinz’s attempt to overcome this obstacle. The paper argues that, prima facie, proxytypes are as incapable of accounting for the structure of the linguistic mind as are the more traditional species of empiricism. This position is then confirmed by looking in detail at two suggestions (one derived from recent connectionist research) from Prinz of how certain aspects of syntactic structure might be accommodated by the proxytype theory. It is shown that the suggestions fail to come to terms with both the data and theory of contemporary linguistics.

In his new book, Furnishing the mind, Jesse Prinz argues that a new form of empiricism can break the logjam that currently frustrates attempts to develop a theory of concepts. I argue that Prinz's new way with empiricism is ultimately unsuccessful. In maintaining that all cognition is reducible to perceptual constructs, Prinz is unable to provide an effective model of the nature of individual concepts or their role in thought. Three major problems are addressed in reverse order. Prinz does not show how abstract concepts can be reduced to perceptual states. His commitment to a modal theory of cognition requires the existence of a rich nonperceptual linking system that cannot be accounted for within his empiricism. Finally, his commitment to what he calls proxytypes is not compatible with the individuation of individual concepts. As a consequence, it is impossible to delineate the content of individual thoughts.

In Furnishing the Mind, Jesse Prinz attempts to swing the pendulum back toward empiricism.
