This book has three principle aims: to show that neither vision nor mental imagery involves the creation or inspection of picture-like mental representations; to defend the claim that our visual processes are, in significant part, cognitively impenetrable; and to develop a theory of “visual indexes”. In what follows, I assess Pylyshyn’s success in realising each of these aims in turn. I focus primarily on his arguments against “picture theories” of vision and mental imagery, to which approximately half the book is (...) devoted. I argue that Pylyshyn adopts an unnecessarily restricted interpretation of what it would be for mental representations to be picture-like, and that this leads him prematurely to reject the possibility of explaining the introspective evidence concerning the nature of mental imagery.

The aim of this essay is to outline a conceptual framework for a type of philosophy (or approach to philosophy) to be herein called “non-sentential philosophy.” Although I will primarily concern myself with the conceptual coherence of the framework in this essay, illustrations will be provided to show that the notion has rich implications for comparative studies. In particular, I believe this theoretical framework will be of interest to those looking for a way to capture the differences between certain non-Western (...) philosophical traditions—such as Chinese philosophy—and Western philosophy, a tradition in which the sentential approach is dominant.

Simulation Theory says we need not rely exclusively on prepositional knowledge of other minds in order to explain the actions of others. Seeking to know what you will do, I imagine myself in your situation, and see what decision I come up with. I argue that this conception of simulation naturally generalizes: various bits of our mental machine can be run‘off‐line’, fulfilling functions other than those they were made for. In particular, I suggest that visual imagery results when the visual (...) system is run off‐line. I briefly review the empirical evidence and consider the philosophical implications, particularly concerning the mode of mental representation in imagery. (shrink)
