Drayson, Z. (2023). Truth, success, and epistemology: A response to Stokes’s Thinking and Perceiving. Philosophy and the Mind Sciences, 4. (Original work published July 5, 2023)


In Thinking and Perceiving, Stokes challenges “the pernicious cognitive effects assumption”: the assumption that it would be epistemically problematic if our thoughts were to directly influence our perceptual experience. In doing so, Stokes takes himself to be supplementing the epistemological claims of philosophers like Siegel and Lyons with descriptive claims about human psychology. I argue that his conclusions are more radical than they first appear, to the extent that Stokes’s project is at odds with the standard epistemological discussions of cognitive penetration.
