Leading experts in the field contributing to this volume make the case for the singularity of thought and debate a broad spectrum of issues it raises, including ...

As a class of terms and mental representations, proper names and mental names possess an important function that outstrips their semantic and psycho-semantic functions as common, rigid devices of direct reference and singular mental representations of their referents, respectively. They also function as abstract linguistic markers that signal and underscore their referents' individuality. I promote this thesis to explain why we give proper names to certain particulars, but not others; to account for the transfer of singular thought via communication with (...) proper names; and, more generally, to support a cognitivist, not acquaintance or instrumentalist, theory of singular thought.

Overview The debate over the semantics of proper names has, of late, heated up, focusing on the relative merits of referentialism and predicativism. Referentialists maintain that the semantic function of proper names is to designate individuals. They hold that a proper name, as it occurs in a sentence in a context of use, refers to a specific individual that is its referent and has just that individual as its semantic content, its contribution to the proposition expressed by the sentence. Furthermore, (...) a proper name contributes its referent to the proposition expressed by virtue of mechanisms of direct reference to individuals, not by virtue of expressing properties. Predicativists embrace an opposing view according to which proper names are just a special kind of common noun. Their semantic function is to designate properties of individuals. A proper name, as it occurs in a sentence in a context of use, expresses a property, and that property is its contribution to the proposition expr .. (shrink)

Donnellan famously argued that while one can fix the reference of a name with a definite description, one cannot thereby have a de re belief about the named object. All that is generated is meta-linguistic knowledge that the sentence “If there is a unique F, then N is F” is true. Donnellan’s argument and the sceptical position are extremely influential. This article aims to show that Donnellan’s argument is unsound, and that the Millian who embraces Donnellan’s scepticism that the reference-fixer (...) cannot secure the relevant de re belief faces a serious problem: Millianism about names plus scepticism about the reference-fixer’s de re belief conflicts with what seems to be an analytical thesis about the relationship between semantic content and understanding. The upshot is that the Millian has good reason to seek an alternative to scepticism. (shrink)

Infallibilism about a priori justification is the thesis that for an agent A to be a priori justified in believing p, that which justifies A's belief that p must guarantee the truth of p. No analogous thesis is thought to obtain for empirically justified beliefs. The aim of this article is to argue that infallibilism about the a priori is an untenable philosophical position and to provide theoretical understanding why we not only can be, but rather must be, a priori (...) justified in believing some false propositions. The argument develops notions of obviousness and conceptual understanding as a means of affording insight into the conditions for having a priori justification and, consequently, into why infallibilism cannot stand.

Controversy remains over exactly why Frege aimed to estabish logicism. In this essay, I argue that the most influential interpretations of Frege's motivations fall short because they misunderstand or neglect Frege's claims that axioms must be self-evident. I offer an interpretation of his appeals to self-evidence and attempt to show that they reveal a previously overlooked motivation for establishing logicism, one which has roots in the Euclidean rationalist tradition. More specifically, my view is that Frege had two notions of self-evidence. (...) One notion is that of a truth being foundationally secure, yet not grounded on any other truth. The second notion is that of a truth that requires only clearly grasping its content for rational, a priori justified recognition of its truth. The overarching thesis I develop is that Frege required that axioms be self-evident in both senses, and he relied on judging propositions to be self-evident as part of his fallibilist method for identifying a foundation of arithmetic. Consequently, we must recognize both notions in order to understand how Frege construes ultimate foundational proofs, his methodology for discovering and identifying such proofs, and why he thought the propositions of arithmetic required proof.

The epistemological argument against descriptivism about proper names is extremely simple. For a proper name ‘N’ and definite description ‘F’, the proposition expressed by “If N exists, then N is F” is not normally known a priori. But descriptivism about proper names entails otherwise. So descriptivism is false. The argument is widely regarded as sound. This paper aims to establish that the epistemological argument is highly unstable. The problem with the argument is that there seems to be no convincing rationale (...) for the first premise that is independent of a view about the nature of the proposition expressed by the sentence “If N exists, then N is F”.

This paper offers a defense of Charles Parsons’ appeal to mathematical intuition as a fundamental factor in solving Benacerraf’s problem for a non-eliminative structuralist version of Platonism. The literature is replete with challenges to his well-known argument that mathematical intuition justifies our knowledge of the infinitude of the natural numbers, in particular his demonstration that any member of a Hilbertian stroke string ω-sequence has a successor. On Parsons’ Kantian approach, this amounts to demonstrating that for an “arbitrary” or “vaguely represented” (...) string of strokes, we can always “add” one more stroke. Critics have contested the cogency of a notion of an arbitrary object, our capacity to vaguely represent a definite object, and the role of spatial and temporal representation in the demonstration that we can “add” one more. The bulk of this paper is devoted to demonstrating how to meet all extant criticisms of his key argument. Critics have also suggested that Parsons’ whole approach is misbegotten because the appeal to mathematical intuition inevitably falls short of providing a complete solution to Benacerraf’s problem. Since the natural numbers are essentially and exclusively characterized by their structural properties, they cannot be identified with any particular model of arithmetic, and thus a notion of intuition will fail to capture the universality of arithmetic, its applicability to all entities. This paper also explains why we should not reject appeal to mathematical intuition even though it is not itself sufficient to fully “close the gap” on Benacerraf’s challenge. (shrink)

In this paper, I assess the relative merits of two semantic frameworks for slurring terms. Each aims to distinguish slurs from their neutral counterparts via their semantics. On one, recently developed by Kent Bach, that which differentiates the slurring term from its neutral counterpart is encoded as a ‘loaded’ descriptive content. Whereas the neutral counterpart ‘NC’ references a group, the slur has as its content “NC, and therefore contemptible”. On the other, a version of hybrid expressivism, the semantically encoded aspect (...) of a slurring term that distinguishes it from its neutral counterpart is, rather, expressed. A speaker who uses the slurring term references the group referenced by the neutral counterpart and, in addition, expresses her contempt for the target. On this view, while the speaker’s attitude may be evaluated for appropriateness, the expressivist component of slurring terms is truth-conditionally irrelevant. The reference to the group, and only the reference to the group, contributes to truth conditions. I’ll argue that hybrid expressivism offers a more parsimonious analysis of slurs’ projective behavior than loaded descriptivism and that its truth conditional semantics is not inferior to the possible accounts available for loaded descriptivism. I also meet Bach’s important objection that hybrid expressivism cannot account for uses of slurring terms in indirect quotation and attitude attributions. (shrink)

Clarence Sloat, Ora Matushansky, and Delia Graff Fara advocate a Syntactic Rationale on behalf of predicativism, the view that names are predicates in all of their occurrences. Each argues that a set of surprising syntactic data compels us to recognize names as a special variety of count noun. This data set, they say, reveals that names’ interaction with the determiner system differs from that of common count nouns only with respect to the definite article ‘the’. They conclude that this special (...) distribution of names is best explained by the-predicativism, the view that posits the existence of the null-determiner ‘the’ preceding bare singular names. This essay argues that they have incorrectly discerned the syntactic facts: their critical data point concerning the ungrammaticality of sentences like “The Katherine wants coffee” is mistaken. Such sentences’ grammaticality undermines the Syntactic Rationale and presents serious auxiliary problems for predicativism. (shrink)

The Identity of Indiscernibles is the principle that there cannot be two individual things in nature that are qualitatively identical. The principle is not exactly popular. Michael Della Rocca tries to resurrect it by arguing that we must accept this principle, for otherwise we cannot explain the impossibility of completely overlapping indiscernible objects of the same kind that share all their parts and exist in the same place at the same time. I try to show that his argument goes wrong: (...) we need not embrace the identity of indiscernibles to deal with the co-location problem. (shrink)

In In Defense of Pure Reason [IDPR], BonJour advances a version of moderate rationalism, the thesis that rational insight is an independent, though fallible, source of a priori epistemic justification. To demonstrate that this thesis must obtain, BonJour argues that rational insight is truth conducive and that no infallibilist rationalist theory could be correct. This article aims to establish two points: (1) BonJour’s argument for the fallibilist thesis is problematic because it invokes implausible conditions on justification, conditions that even BonJour (...) rejects; (2) BonJour’s argument for the truth conduciveness of rational insight fails because it does not (and cannot) account for the truth-conduciveness of fallible rational insights.
