Noun phrases (NPs) beginning with the or a/an are prototypical definite and indefinite NPs in English. The two main theories about the meaning of definiteness are uniqueness and familiarity. Both properties characterize most occurrences of definite descriptions although there are examples which defy one or the other or both theories. Existential sentences have become criterial for distinguishing indefinites from definites, and have led to broadening of both categories to include a variety of other NP forms. Information status approaches propose a (...) hierarchy of NP types, rather than a simple binary distinction. The expression of definiteness varies from language to language. (shrink)

A common objection to Russell's theory of descriptions concerns incomplete definite descriptions: uses of (for example) ‘the book is overdue’ in contexts where there is clearly more than one book. Many contemporary Russellians hold that such utterances will invariably convey a contextually determined complete proposition, for example, that the book in your briefcase is overdue. But according to the objection this gets things wrong: typically, when a speaker utters such a sentence, no facts about the context or the speaker's communicative (...) intentions single out a particular description-theoretic proposition as the proposition expressed. However, this is an objection only if it is assumed that successful linguistic communication requires the hearer to identify a proposition uniquely intended by the speaker. We argue that this assumption is mistaken. On our view, no proposition, descriptive or referential, is uniquely intended in such a context; thus, no proposition can nor need be identified as the proposition expressed. One significant upshot is that, once the aforementioned assumption is rejected, incompleteness no longer poses a threat to Russell's theory of descriptions. (shrink)

Logicism is one of the great reductionist projects. Numbers and the relationships in which they stand may seem to possess suspect ontological credentials – to be entia non grata – and, further, to be beyond the reach of knowledge. In seeking to reduce mathematics to a small set of principles that form the logical basis of all reasoning, logicism holds out the prospect of ontological economy and epistemological security. This paper attempts to show that a fundamental logicist project, that of (...) defining the number one in terms drawn only from logic and set theory, is a doomed enterprise. The starting point is Russell''s Theory of Descriptions, which purports to supply a quantificational analysis of definite descriptions by adjoining a ''uniqueness clause'' to the formal rendering of indefinite descriptions. That theory fails on at least two counts. First, the senses of statements containing indefinite descriptions are typically not preserved under the Russellian translation. Second (and independently), the ''uniqueness clause'' fails to trim ''some'' to ''one''. The Russell–Whitehead account in Principia Mathematica fares no better. Other attempts to define ''one'' are covertly circular. An ontologically non-embarrassing alternative account of the number words is briefly sketched. (shrink)
