Asher and Lascarides maintain that speech act types, the sorts of linguistic actions described and categorized, most influentially, by Austin and Searle are rhetorical relations. This relational account of speech acts is problematic for two reasons: Despite Asher and Lascarides ingenious appeal to dot type speech acts, the relational account is incompatible with the widespread phenomenon of indirect speech; only some speech acts are plausibly identified with rhetorical relations. These problems can be solved if a distinction between two kinds of speech act is recognized: Discourse-structuring speech acts are performed upon utterances and thus are plausibly identified with rhetorical relations, while non-discourse-structuring speech acts are performed upon conversational participants and thus are not plausibly identified with such relations. The typologies for these two kinds of speech acts cut across one another, and this suggests a promising approach to the phenomenon of indirect speech acts.

Strawson :96–118, 1964) argued that definite NPs trigger presuppositions as an aspect of their conventional meanings, and this semantic conception of presupposition triggers is incorporated into the binding theory of presuppositions. The phenomenon of presupposition denials, however, presents a problem for the semantic conception of presupposition triggers, for in such denials the alleged semantic presuppositions seem to be “cancelled” by a negation operator. Geurts :274–307, 1998; Presupposition and pronouns, 1999) attempts to solve this problem by utilizing the binding theory’s allowance for local accommodation. Geurts’ proposal, however, is inadequate, primarily because Geurts formulates the binding theory within discourse representation theory, which makes no allowance for the illocutionary force of denial. Asher and Lascarides’ segmented discourse representation theory, however, has the resources to account for the illocutionary force of denial. Utilizing a version of SDRT I demonstrate that the “cancelling” of a presupposition by echoic negation in presupposition denials crucially depends upon the denial of information that is pragmatically communicated by accommodation.

Truth conditional semantics is the project of ‘determining a way of assigning truth conditions to sentences based on A) the extension of their constituents and B) their syntactic mode of combination’. This research program has been subject to objections that take the form of underdetermination arguments, an influential instance of which is presented by Travis: … consider the words ‘The leaf is green,’ speaking of a given leaf, and its condition at a given time, used so as to mean what they do mean in English. How many distinct things might be said in words with all that true of them? Many.… Suppose a Japanese maple leaf, turned brown, was painted green for a decoration. In sorting leaves by colour, one might truly call this one green. In describing leaves to help identify their species, it might, for all the paint, be false to call it that.

Several of the better essays in On Quine are critical of Quine’s views. In “Against Naturalized Epistemology,” Bas Van Fraassen challenges empiricists to provide a self-consistent statement of their view; if empiricism is the view that “experience is our one and only source of information,” then that piece of information must itself have experience only as its source. Van Fraassen argues that Quine’s naturalized epistemology cannot meet this challenge and thus “is itself a metaphysics of the sort which empiricists disdain”. Barry Stroud argues in “Quine on Exile and Acquiescence” that there is a tension between Quine’s thesis of “immanence”—that we can work only from within our language and/or conceptual scheme—and Quine’s doctrine of the indeterminacy of translation. And in “Quine’s Experiment with Intensional Objects and His Existentialist Quantified Modal Logic,” Hector-Neri Castañeda explores how “pseudo-Quine,” the Quine who experimented with modal logic in his 1947, might respond to the attack on quantified modal logic presented in his 1961.
