Doctor of Philosophy / Many criticisms of the prevalent deflationary theories of truth stem from some misunderstanding. Clarification can be found from considering Quine's reasoning on the disquotational feature of the truth predicate. Quine's disquotationalism and Horwich's minimalism are similar theses with respect to the concept of truth, though the difference between the choices of the primary truth bearers and the divergence in their accounts of meaning and reference are striking. Chapter Two is devoted to making plain Quine's reasoning regarding the disquotational concept of truth, and to constructing a disquotational theory of truth. Also in this chapter, the topic of how to enhance the deductive power of this theory is discussed. The following chapter aims to square Quine's theses of inscrutability of reference and ontological relativity, with an account of the disquotational schema of reference. Whether or not a disquotational schema of reference and all its instances can be seen as providing a genuine reference scheme, as claimed by Horwich and most deflationists, is also discussed. In Chapter Four, after an introduction of Horwich's minimalist conception of truth, there are a number of issues considered, in particular Horwich’s use-theoretic account of meaning and compositionality, along with the divergence between his account of meaning and Quine's. The final chapter, Chapter Five, provides a thorough analysis of three important factors regarding the disquotational theory and the minimal theory of truth. Among them, the first factor discussed is what sort of equivalence relation occurs within each instance of the disquotational schema or each axiom of the equivalence schema. Following this, there is an analysis of in what way the disquotationalist and the minimalist can explain all general facts involving truth. The last factor involves considering the proper ascription of the disquotational or the minimal truth predicate. Along with the analysis of these three factors, the issue regarding which theory of truth is preferable is elaborated.
