Abstract

The dissertation consists of two parts: a negative part and a positive part. The negative part is a critical examination of a contemporary approach to the problem of truth, deflationism, which argues against the traditional substantive approach. The positive part provides an account of truth, called 'substantive quietism', which attempts to preserve and develop what are reasonable in the contrary theories. ;The approach of the critical examination is analytic and critical, not historical or expository. I focus on the core idea and the basic line of deflationism as a whole. The critical examination consists of a general characterization of deflationism and two case analyses . ;The basic moral drawn from the critical examination is this: there are different projects intended to answer different questions concerning truth; those theses in different projects might be compatible with each other; however, an advocate of a certain theory of truth might mistake what he has done actually for one project to meet the demands of quite another. My basic conclusion is this: in spite of its brilliant linguistic descriptions of the logico-syntactic function of the truth predicate, deflationism fails to justify its core idea, i.e., truth is not substantive, by virtue of the descriptions, because the substantive notion of non-linguistic truth turns out to be compatible with the linguistic descriptions. ;Drawing upon the morals from the critical examination, the positive part is a theoretical construction of substantive quietism, which consists of a theory of truth called 'substantive quietist theory' and my surrounding arguments on behalf of its adequacy. SQT is composed of an account of non-linguistic truth and an account of the linguistic truth predicate. The former provides a general definition of what it is to be a definition of truth and a definition of truth, attempting to capture our pretheoretic understanding of non-linguistic truth with minimal explanatory resources. The latter endeavors to characterize the situated uses of the truth predicate that constitute its raison d'etre by an epistemico-pragmatic notion of the truth predicate
