Abstract
The author of this work has attempted a detailed analysis of those aspects of visual perception which he takes to be of vital importance to the epistemologist. The epistemological problems which form the background of his work are primarily those raised by Realist theories of perception. By tackling the problems raised by Realist theories, and at the same time rejecting Phenomenalism, Professor Dretske has made a useful contribution to philosophical analyses of perception. He has, I believe, been partly successful in showing that the dichotomy ‘either Realist or Phenomenalist’ need not be a real one; that rigid Realist theories such as those of Ryle, Chisholm, and Armstrong need not be the only viable alternatives to Phenomenalism.
