Fragmentation (regarding belief) is roughly the view that a single agent has various separate systems of belief, which need not make for a consistent and deductively closed overall system. But does it make sense to speak of the human mind as fragmented? How can Fragmentation be spelled out in more precise terms? Are there real architectual features of the mind that are best described by a theory of fragmentation? And can a theory of fragmentation help us solve some of philosophy’s perennial problems and puzzles? These are some of the questions we address in the project.
