research overview

  • My current research focuses on three projects. First, what makes our perceptual beliefs justified? Does perceptual justification require evidence of perceptual reliability. Many authors say it does not because they want to avoid circularity. I defend the view that it does. Second, I investigate the question of how one can know that one is not a brain-in-a-vat (alternatively, that one is not in the Matrix). Third, regarding the question of whether we have direct control over our beliefs, most authors argue that we do not. I argue that we do.
