Abstract
This article explains precisely in what sense the Nyaya philosophers promote a correspondence theory regarding the nature of truth. It also explains how truth may be inferred from successful effort and argues that successful effort can be produced only by true awareness. While successful effort is the major test of truth, other tests of truth in the Nyaya view should be recognized as and when appropriate. Thus, that if the pervaded belongs to something, the pervader too belongs to that thing may be known to be true by the mind alone without reference to the inferential test of truth. Truth is in most cases extrinsic in the sense that truth of an awareness is determined with reference to another awareness. This does not lead to a vicious infinite regress; in some cases, as in the pervaded-pevader case or in the case there is cognition where there can be no cognition that there is cognition unless there is cognition, truth is intrinsic and may be determined without reference to another awareness.
