Mental fragmentation is the thesis that the mind is fragmented, or compartmentalized. Roughly, this means that an agent's overall belief state is divided into several sub-states-fragments. These fragments need not make for a consistent and deductively closed belief system. The thesis of mental fragmentation became popular through the work of philosophers like Christopher Cherniak, David Lewis, and Robert Stalnaker in the 1980s, and has recently attracted increased attention.This volume is the first collection of essays devoted to the topic of mental fragmentation. It features important new contributions by leading experts in the philosophy of mind, epistemology, and philosophy of language. Opening with an accessible introduction providing a systematic overview of the current debate, the fourteen essays cover a wide range of issues: foundational issues and motivations for fragmentation, the rationality or irrationality of fragmentation, fragmentation's role in language, the relationship between fragmentation and mental files, and the implications of fragmentation for the analysis of implicit attitudes.
