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.

Indexicalism is a strategy for defending truth-conditional semantics from under-determination arguments. According to indexicalism the class of indexical expressions includes not only the obvious indexicals, e.g. demonstratives and personal pronouns, but also unobvious indexical expressions, expressions which allegedly have been discovered to be indexicals. This paper argues that indexicalism faces significant obstacles that have yet to be overcome. The issue that divides indexicalism and truth-conditional pragmatics is first clarified. And then three general problems for indexicalism are presented, and some potential solutions that have been proposed in its defense are criticized.

Fodor (Mind Lang 16:1–15, 2001 ) endorses the mixed view that thought, yet not language, is compositional. That is, Fodor accepts the arguments of radical pragmatics that language is not compositional, but he claims these arguments do not apply to thought. My purpose here is to evaluate this mixed position: Assuming that the radical pragmaticists are right that language is not compositional, what arguments can be provided in support of the claim that thought is compositional? Before such arguments can be evaluated, the relevant notion of compositionality must be clarified. So I first clarify this notion of compositionality, and then consider three arguments in support of the mixed position. All three of these arguments are found to be inadequate, and thus I conclude that the mixed position is unstable: If one endorses the arguments of radical pragmatics against the compositionality of language, then one should also reject the compositionality of thought.

En "Existenciales negativos como denegaciones metalingüísticas" (García 2012), Eduardo García presenta una propuesta metalingüística sobre los existenciales negativos y argumenta en contra de la propuesta de la corrección dinámica (Clapp 2008). Aquí argumento que aunque la posición de García es atractiva porque satisface un criterio importante que muchas interpretaciones de los existenciales negativos no logran hacer justicia, no presenta una posición convincente en contra de la propuesta de la corrección dinámica ni a favor de su propuesta metalingüística. In his "Existenciales negativos como denagaciones metalinguísticas" (García 2012) Eduardo García presents a metalinguistic approach to negative existentials, and he argues against the dynamic correction proposal (Clapp 2008). Here I argue that García's proposal is attractive because it satisfies an important criterion that many approaches to negative existentials do not satisfy. However, I also argue that García has made neither a persuasive case against the dynamic correction proposal, nor a persuasive case in favor of his metalinguistic proposal.

The problem of negative existentials arises because utterances of such sentences have the paradoxical feature of denying what they presuppose, thus undermining their own truth. There are only two general strategies for solving the problem within the constraints traditional static semantics, and both strategies attempt to explain away this paradoxical feature. I argue that both strategies are fundamentally flawed, and that an adequate account of negative existentials must countenance, and not explain away, this paradoxical feature. Moreover, I argue that a framework of dynamic semantics can achieve this result. Thus negative existentials provide a case in support of dynamic semantics.
