Singular Thought and Mental Files

Abstract

This introduction outlines some central challenges to a clear understanding of singular (or de re) thought, and illustrates why the literature has recently turned to the notion of a mental file as a way to theorize it. It sketches three central motivations behind the claim that singular thought is file-based thought. First, file-theorists have stressed that the descriptive information contained in a file does not determine its identity conditions or semantic content. Second, it is sometimes assumed that singular thoughts are devices of de jure coreference in thought and claimed that mental files are the cognitive reality of de jure coreference in thought. Finally, the file-theoretic approach to singular thought may seem to lend empirical respectability to the notion of singular thought. The chapter ends by?introducing some basic questions proponents of this approach must address if it is to fulfill its explanatory aims.
