Abstract
This is a symposium on _Thinking and Perceiving_, a single authored monograph that argues that thought not only affects sensory perception, but sometimes improves it, and sometimes to the point of epistemic virtue. The case for these claims is empirically grounded, with special emphasis on studies on perceptual expertise. The symposium includes an introduction by the author, and three critical commentaries--by Amy Kind, Casey O'Callaghan, and Wayne Wu--concluding with a reply by the author. The discussion is wide ranging, including: attention, cognitive penetrability or perception, the modularity of mind; computational analyses of mind, imagination, imaginative skill and expertise; theory-ladenness of perception; objectivity; perceptual content and perceptual success.
