Of his numerous investigations ... Tarski was most proud of two: his work on truth and his design of an algorithm in 1930 to decide the truth or falsity of any sentence of the elementary theory of the high school Euclidean geometry. [...] His mathematical treatment of the semantics of languages and the concept of truth has had revolutionary consequences for mathematics, linguistics, and philosophy, and Tarski is widely thought of as the man who "defined truth". The seeming simplicity of his famous example that the sentence "Snow is white" is true just in case snow is white belies the depth and complexity of the consequences which can be drawn from the possibility of giving a general treatment of the concept of truth in formal mathematical languages in a rigorous mathematical way. (J.W. Addison).

Marian David defends the correspondence theory of truth against the disquotational theory of truth, its current major rival. The correspondence theory asserts that truth is a philosophically rich and profound notion in need of serious explanation. Disquotationalists offer a radically deflationary account inspired by Tarski and propagated by Quine and others. They reject the correspondence theory, insist truth is anemic, and advance an "anti-theory" of truth that is essentially a collection of platitudes: "Snow is white" is true if and only if snow is white; "Grass is green" is true if and only if grass is green. According to disquotationalists the only profound insight about truth is that it lacks profundity. David contrasts the correspondence theory with disquotationalism and then develops the latter position in rich detail--more than has been available in previous literature--to show its faults. He demonstrates that disquotationalism is not a tenable theory of truth, as it has too many absurd consequences.

Prosentential theorists claim that sentences such as “That’s true” are prosentences that function analogously to their better known cousins–pronouns. For example, just as we might use the pronoun ‘he’ in place of ‘James’ to transform “James went to the supermarket” into “He went to the supermarket,” so we might use the prosentenceforming operator ‘is true’ to transform “Snow is white” into “‘Snow is white’ is true.” According to the prosentential theory of truth, whenever a referring expression (for example, a definite description or a quote-name) is joined to the truth predicate, the resulting statement contains no more content than the sentence(s) picked out by the referring expression. To assert that a sentence is true is simply to assert or reassert that sentence; it is not to ascribe the property of truth to that sentence. The prosentential theory is one kind of deflationary theory of truth. Like all deflationary theories, it provides an alternative to explanations of truth that analyze truth in terms of reference, predicate satisfaction or a correspondence relation.

Thought and World has three main concerns.1 First, it presents and defends a deflationary theory of propositional truth—that is, a deflationary theory of the concept of truth that figures in claims like the proposition that snow is white is true. I have long admired the deflationary theory of truth that Paul Horwich developed in the eighties, but I have also had substantial misgivings about that theory.2 In writing TW I was concerned to formulate an alternative view that enjoys the virtues of Horwich’s theory while lacking its defects. Second, the book presents deflationary accounts of our relational semantic con- cepts—for example, the concept of reference that figures in the proposition the concept of the Evening Star refers to the planet Venus, and the concept of expression that figures in the proposition the concept of a triangle expresses the property triangularity. Third, the book provides an account of our correspondence intuitions. As we all recognize, commonsense semantics includes a concept of semantic correspondence: we are all prepared to say, for example, that the proposition that snow is white corresponds semantically to the state of affairs snow’s being white, and that the proposition that the uni- verse is expanding corresponds semantically to a state of affairs that actually obtains. I wanted to explain the relationship between this concept and the concept of propositional truth, to identify the factors that make the concept useful, and, most importantly, to show that it is possible to extend deflation- ism so as to provide an analysis of the concept. (The concept of correspon- dence stands for a relation between propositions and states of affairs. What I maintain in the book is that this relation can be characterized in deflationary terms. I do not maintain that it is possible to give a deflationary account of..

: In this essay, Solis contemplates how queercrip—both homosexual and disabled—readings of four editions of "Snow White and the Seven Dwarfs" might be used to destabilize "normative" sexual identities. His goal is to argue against secrecy and for disclosure; thus, a main question guides the analysis: How might we (for example, parents, teachers, counselors) use picture books to reevaluate human sexuality in all its varied manifestations to avoid condemning to the closet all those who do not approximate a prescribed "norm"?

It is often thought that instances of the T-schema such as snow is white is true if and only if snow is white state correspondences between sentences andthe world, and that therefore such sentences play a crucial role in correspondence theories oftruth. I argue that this assumption trivializes the correspondence theory: even a disquotationaltheory of truth would be a correspondence theory on this conception. This discussionallows one to get clearer about what a correspondence theory does claim, and toward the end of thepaper I discuss what a true correspondence theory of truth would involve.

According to the deflationary theory of truth, to assert that a statement is true is just to assert the statement itself. For example, to say that ‘snow is white’ is true, or that it is true that snow is white, is equivalent to saying simply that snow is white, and this, according to the deflationary theory, is all that can be said significantly about the truth of ‘snow is white’.

Is truth a substantial feature of truth-bearers? Correspondence theorists answer in the affirmative, deflationists in the negative. Correspondence theorists cite in their defense the dependence of truth on meaning or representational content. Deflationists in turn cite the conceptual centrality of simple equivalences such as ''Snow is white' is true iff snow is white'' and 'It is true that snow is white iff snow is white'. The apparent facts to which these theorists appeal correspond to some of our firmest and most basic convictions about truth. An account of truth that fails to accommodate either sort of apparent fact is inadequate. The account presented in this essay attempts to avoid this inadequacy by 'deflating' truth for propositions but 'inflating' truth for entities that express propositions, thus drawing from the insights of both deflationists and correspondence theorists.
