How does thinking in terms of truth contribute to our knowledge of the world? Moreover, what might the answers to this question tell us about truth itself? The aim of this paper is to canvas several roles of the truth concept for first-order inquiry (that is, inquiry into extra-linguistic and extra-mental reality) and then relate these answers to the ongoing inflationism-deflationism debate. I argue that the deflationary conception of truth is more versatile than is often appreciated, but there is nonetheless one role that is uniquely inflationary. I call this role ‘representing semantic determinants’. In short, I argue that inflationism permits substantive explanations of the truth-conditional semantic facts and that such explanations can occasionally play a role in investigating certain first-order claims.

An object-based correspondence theory of truth holds that a truth-bearer is true whenever its truth conditions are met by objects and their properties. In order to develop such a view, the principal task is to explain how truth-bearers become endowed with their truth conditions. Modern versions of the correspondence theory see this project as the synthesis of two theoretical endeavours: basic metasemantics and compositional semantics. Basic metasemantics is the theory of how simple, meaningful items (e.g. names and concepts) are endowed with their contributions to truth conditions, and compositional semantics is the theory of how the meanings of simple items compose to generate (among other things) the truth conditions of sentences. Understanding truth along these broad lines was once popular; it was first championed by Field (1972). However, the once-popular conception of its tasks included an over-ambitious view of basic metasemantics. It was thought that reference needed to be analyzed (or reduced a posteriori) in terms of more fundamental, non-semantic relations (e.g. causal relations, indication, or teleological relations, in the case of mental representation). Obstacles in providing such an analysis engendered skepticism towards this understanding of truth and eventually gave way to its deflationary competitors. This dissertation aims to defend the modern, object-based correspondence theory against its rivals—especially deflationism. Chapter one provides a historically-grounded overview of the theory. Chapter two identifies two points of contrast between the correspondence theorist and the deflationist: they employ different orders of explanation for the variety of semantic phenomena, and they (traditionally) take different attitudes towards the prospects of reduction. Situating the dialectic in this way allows me to develop a middle ground: a moderate version of inflationism that takes the inflationary explanatory structure and combines it with a non-reductive, pluralist approach to basic metasemantics. Chapter three expands on the details of this pluralist account of reference. Chapter four contrasts the view with another rival approach to basic metasemantics: metasemantic interpretationism. And finally, chapter five applies the theory to answer another question of broad philosophical interest: what role does our conception of truth play in inquiry about the world?

This essay argues for a two-part thesis concerning the deflationist theories of truth and reference. First, I identify two points of contrast between the deflationist theories and their traditional inflationary opponents: (1) they each employ different orders of explanation for the variety of semantic phenomena, and (2) the inflationist is typically taken to be beholden to a reductive explanation of reference, whereas the deflationist is doubtful of this project. Secondly, I argue that these two points of contrast need not come together to exhaust the space of possible views. There is room for a plausible middle ground: a moderate version of inflationism. My moderate inflationism will reject the deflationist's order of explanation, so it counts as genuinely inflationary. However, it also rejects the reductionist ambitions of the earlier inflationists, so it isn’t an apt target for deflationary scepticism.

A theory of truth is language-transcendent if it ascribes truth conditions to truth-bearers that are not expressible in our natural language; a theory is language-immanent if it is not language-transcendent. In this paper, I argue for the following theses. Whether the correct theory of truth is language-transcendent or language-immanent will have significant consequences for general philosophy. Prima facie, a language-transcendent theory is preferable. However, language-transcendent theories tend to require substantive metaphysical commitments concerning truth. Deflationist theories are particularly interesting in this context. I argue that, if deflationism is to remain consistent with its motivations, then it must opt for a language-immanent conception of truth.
