Michael Dummett’s Semantic Anti-Realism
摘要
Dummett construes that the issue of realism does not centre around the nature of entities; it is rather associated with the nature of truth. The real question is not the objectivity of entities of a certain class; it is rather a question of objective truth of statements of a certain class, and the class possesses an objective truth value independently of our means of knowing it. This has been criticized by Dummett in his proposal of an anti-realist position. The disputed or given class (the class about which the question of objective truth arises) may be that of statements about physical objects or about mental events, or about mathematical entities, or about past or future. Realism about the disputed class is characterized by Dummett as the belief that the statements of the disputed class possess an objective truth-value, that means the statements are true or false independent of any means of recognition. The realist therefore admits evidence transcendent truth of statements in question and every statement of a given class is determinately either true or false. Dummett has argued that this principle cannot operate globally because there is no determinate truth available for a large segment of natural language. It can operate where we can verify the truth/falsity of statements. For him any cognition transcendent truth is beyond our cognition grasp and therefore it remains forever indeterminate and unknowable. If truth is beyond our cognitive grasp, we cannot explain how truth can be ascribed to language at all. We cannot even explain the meaning of statements if truth-conditions of those statements themselves are beyond our knowledge. He holds that the world is empirically real in so far as it is given in experience, but it cannot be transcendentally real as there is no such reality which can be made intelligible at all. Transcendental reality is an incorrect assumption as it has no foothold in our verifiable language. My aim in this paper is to deal with Dummett’s view on meaning where he has discarded the truth-conditional theory of meaning by denying truth to be the central notion in the theory of meaning. He holds that the truth-conditional theory should be substituted by verifiability and hence Dummett’s view is called as semantic anti-realism. The paper also discusses briefly Rorty and Davidson’s view on truth and meaning.
