Abstract

A cognition is a psychological property distinct from the properties of a person's body and objects of sensory experience. A cognition rests or occurs in a self, and for only an instant before giving way to another cognition, each having as content, when veridical, intersubjective objects other than itself. But a cognition is also causally continuous with its objects—in the one direction, through the operation of the sense organs, sight, hearing, and so on, and, in the other, in having a causal role in action undertaken voluntarily. This paper sketches the Nyāya theory of perception with special attention to the arguments of the "New" or late Nyāya philosopher of the fourteenth century, Gangesa, in addressing two thorny areas of the Nyāya picture: (1) focus wanted and unwanted along with apparent cognitive simultaneity in a synthesis of sensory information deriving from the operation of more than one sense organ, and (2) the peculiar sensory connection involved in perception of future instances of universals, illusorty perception, and in recognition of someone or something that one has encountered before.
