The central claim of this thesis is that concepts, the components from which cognitively significant truth evaluable content (thought) is composed, are unstructured entities an account of whose individuation makes no essential reference to other concepts in the possession of the thinking subject or to any particular means by which the reference of the concept is identified by the thinking subject. This position is called Conceptual Atomism and contrasts with Inferential Role Semantics, according to which concepts are individuated by their (...) inferential roles or their conditions of warranted application. The structure of the argument is as follows. Firstly, a principle called the Transparency Principle is developed. This places constraints on the individuation of concepts across differing contexts. The Transparency Principle is then used to show that Inferential Role Semantics is false because it cannot provide a satisfactory account of cognitive dynamics; that is, of the conditions under which a concept is retained through changes in the epistemic state of the subject over a period of time. A version of Conceptual Atomism is then defended and it is shown that this theory yields the correct individuation of concepts. According to this theory the concepts of an individual subject are individuated in terms of referential episodes, episodes of ongoing reference to an object or property during which it is diachronically transparent to the subject that the same thing is being referred to. The more general notion of a referential practice is then used to account for the sharing of concepts by more than one person. Finally, a novel account of the thoughts expressed using indexical terms is defended in order to show that indexicals present no counterexample to Conceptual Atomism. This account of indexical thoughts is of some consequence in its own right. (shrink)

In Reference and Reflexivity, John Perry tries to reconcile referentialism with a Fregean concern for cognitive significance. His trick is to supplement referential content with what he calls ‘‘reflexive’’ content. Actually, there are several levels of reflexive content, all to be distinguished from the ‘‘official,’’ referential content of an utterance. Perry is convinced by two arguments for referentialism, the ‘‘counterfactual truth-conditions’’ and the ‘‘same-saying’’ arguments, but he also acknowledges the force of two Fregean arguments against it, arguments that pose the (...) ‘‘coreference’’ and the ‘‘no-reference’’ problems. He sees these as genuine problems for referentialism and does not share Howard Wettstein’s (1986) view that semantics has ‘‘rested on a mistake,’’ the mistake of thinking that semantics is obliged to come to grips with ‘‘cognitive significance’’ and, in particular, to explain the fact that coreferring terms can differ in cognitive significance and that terms lacking in reference can still have cognitive significance. Perry points out that ‘‘there is nothing in [the arguments for referentialism] to show that the official content, rather than the reflexive content, is the key to understanding the cognitive motivation and impact of utterances’’ (Perry 2001, 193).1 In other words, ‘‘a theory of direct reference provides no argument for ignoring reflexive content, and, properly understood, has no motivation for searching for such an argument.’’ Thus Perry uses the notion of reflexive content to complement referentialism with a theory of cognitive significance. Frege drew a fundamental distinction between the reference of a term and the means by which its reference is determined. In his view, however, it is not the references themselves but the means by which they are determined that enter into propositions (‘‘Thoughts’’) expressed by sentences in which the terms occur. So we might call Frege an ‘indirect reference’ theorist. Echoing the introduction to Kaplan’s ‘‘Afterthoughts’’ (1989a), Perry stresses that ‘direct’, as it occurs in ‘direct reference’, does not imply that ‘‘the mechanism of reference is unmediated by the relation of fitting identifying conditions’’ (188).
