# Experience and Evidence **Opening (not a real abstract):** What evidence does perceptual experience provide us with? Why heed the testimony of our senses? To motivate these questions, consider a perceiver and a hallucinator. Percy, the perceiver, accurately perceives a white cup on a desk. Hallie, the hallucinator, suffers a subjectively indistinguishable hallucination as of a white cup on a desk; that is, it seems to her that there is a white cup where in fact there is none. What evidence do Percy and Hallie have for believing that there is a white cup on a desk? I will argue that Hallie has some evidence for her belief, but that Percy has more evidence than Hallie. While standard internalist views have it that Hallie has as much evidence as Percy (e.g. Feldman and Conee 1985), standard externalist views of evidence have it that Hallie has only introspective evidence, **Authors:** [[Susanna Schellenberg]]
