What is the self? And how does it relate to the body? In the second edition of Personal Identity, Harold Noonan presents the major historical theories of personal identity, particularly those of Locke, Leibniz, Butler, Reid and Hume. Noonan goes on to give a careful analysis of what the problem of personal identity is, and its place in the context of more general puzzles about identity. He then moves on to consider the main issues and arguments which are the subject of current debate, including the work of Bernard Williams and Derek Parfit, and makes new and challenging interpretations of them. This new edition contains additional material assessing the biological approach which has become increasingly popular in recent years, and extends the treatment of indeterminate identity to take account of the epistemic view of vagueness. This book covers the problem of personal identity from its origin in Locke's work to the most recent debates in the philosophical literature, and will be invaluablereading for any student of the topic.

An appreciation of Hume's psychology of object identity allows us to recognize certain tensions in his discussion of the origin of our belief in personal identity-tensions which have gone largely unnoticed in the secondary literature. This will serve to provide a new solution to the problem of explaining why Hume finds that discussion of personal identity so problematic when he famously disavows it in the Appendix to the Treatise. It turns out that the two psychological mechanisms which respectively generate the ideas of object and of personal identity are mutually incompatible. It is this sort of conflict within Hume's introspective or subjectivist psychology which is the source of his worry.

Contemporary philosophical discussion of personal identity has centered on refinements and defenses of the “psychological continuity theory”—the view that identity is created by the links between present and past provided by autobiographical experience memories. This view is structured in such a way that these memories must be seen as providing simple connections between two discrete, well-defined moments of consciousness. There is, however, a great deal of evidence—both introspective and empirical—that autobiographical memory often does not provide such links, but instead summarizes, and condenses life experiences into, a coherent narrative. A brief exploration of some of the mechanisms of this summarizing and condensing work furthers the philosophical discussion of personal identity by showing why a view with the structure of the psychological continuity theory will not work, and by illuminating the role of autobiographical memory in the constitution of personal identity.

Among the many topics covered in Sven Bernecker’s impressive study of memory is the relation between memory and personal identity. Bernecker uses his grammatical taxonomy of memory and causal account to defend the claim that memory does not logically presuppose personal identity and hence that circularity objections to memory-based accounts of personal identity are misplaced. In my comment I investigate these claims, suggesting that the relation between personal identity and memory is more complicated than Bernecker’s analysis suggests. In particular, I argue (1) that while he shows that some memories do not presuppose personal identity he fails to show that those that are appealed to in memory-based accounts of personal identity do not, and (2) that the features of his view that allow him to define memory without reference to personal identity also obscure important features of memory that must be part of a complete account.
