INTRODUCTION This book is a systematic study of the problem of perception and knowledge. I intend to analyze the problem, to expound and criticize the most ...

In this paper I wish to propose and defend a form of the Representative Theory of Perception. According to this version of the theory, when a subject perceives some object x to be in a state P1 he does so by being aware of some modfication M1 of some object E. The subject's way of perceiving any one of a range of objects x,y,z, … is that of being aware of some modification of E. It will be a necessary condition (...) of someone's perceiving x to have property P1 that E be modified in some way. And in order for the modifications of E to be representations, a given property P1 will need to be causally related, characteristically, to one or more specific modifications, M1,M2, … Mn, of E. symbolized by ‘X'.).

This is a survey of the development of the philosophy of perception over the past twelve years. There are four sections. Part I deals largely with arguments for the propositionalizing of perception and for those types of externally founded realism that eschew inner representation. Part ii is devoted to three books that put the case for sense-Data (pennycuick, Jackson, Ginet) and some of the arguments against (pitcher). Part iii outlines james j gibson's psychological theory. Part iv takes up the arguments (...) for a theory of 'dual coding', Combining a non-Epistemic inner presentation as a first stage with epistemic selection as an independent module. The mental-Image argument (kosslyn, Pylyshyn) and wittgenstein's remarks on psychology, Recently published, Are brought in as relevant to this issue. (edited). (shrink)

Defining "directly perceive" is made hard enough by the confused and vague ways in which philosophers have used the term, but it is made even more difficult by the fact that it is used quite differently by different philosophers. Two philosophers whose philosophy depends upon a clear understanding of direct perception are Berkeley and Russell. Consider what they say that is relevant to an understanding of their uses of the term. Berkeley, through Philonous, asks Hylas, "Are those things only perceived (...) by the senses which are perceived immediately? Or may those things properly be said to be ’sensible’ which are perceived mediately, or not without the intervention of others?" Russell, in speaking of knowledge by acquaintance, says that "we have acquaintance with anything of which we are directly aware, without the intermediary of any process of inference or any knowledge of truths. Thus in the presence of my table I am acquainted with the sense-data that make up the appearance of my table." Another quite common interpretation is given by Norman Malcolm, who states the definition "A directly perceives x if and only if A’s assertion that he perceives x could not be mistaken.". (shrink)
