 What might give us justification for thinking that our perceptual experiences are reliable? That’s a complicated issue. For our present purposes, let’s consider the following answer: We remember that they have served us well in the past. We are supposing, then, that justification for attributing reliability to your perceptual experiences consists of memories of perceptual success. On this view, a perceptual experience (E) justifies a perceptual belief only when, and only because, you have suitable track-record memories that give you justification for considering (E) reliable. (Of course, this raises the question why those memories give us justification, but there are many different approaches to this question, as we’ll see more fully below.)
