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.

One reason why the Biological Approach to personal identity is attractive is that it doesn’t make its advocates deny that they were each once a mindless fetus.[i] According to the Biological Approach, we are essentially organisms and exist as long as certain life processes continue. Since the Psychological Account of personal identity posits some mental traits as essential to our persistence, not only does it follow that we could not survive in a permanently vegetative state or irreversible coma, but it would appear that none of us was ever a mindless fetus. But what happens to the organism that was a mindless fetus when the _person_ arrives on the scene?[ii] Can the acquisition of thought destroy an organism? That would certainly be news to biologists. Does one organism cease to exist with the emergence of thought and another organism, one identical to the person, take its place? (Burke,1994) That doesn’t seem much more plausible than the previous move. Should identity and Leibniz.

The first book synthesizing the many different topics that surround the issue of personal identity, this text makes an important contribution to the philosophy of personal identity and mind, and to epistemology.

After motivating the general problem of personal identity and considering several possible accounts, this entry reviews a variety of arguments for and against the animalist criterion of personal identity.

In this paper, I compare John Locke’s “memory theory” of personal identity and Memento (directed by Christopher Nolan). I argue that the plot of Memento is ambiguous, in that the main character (Leonard Shelby, played by Guy Pearce) seems to have two histories. As such, Memento is but a series of puzzle cases that intend to illustrate that, although our memories may not be chronologically related to one another, and may even be fused with the memories of other persons, those memories still constitute personal identity. Just as Derek Parfit argues, perhaps there is no personal identity as such, since only survival (in some degree) matters to us. In Memento, Leonard Shelby is not identity to his former self, but survives to some extent.

The Euro-American philosophical traditions offer two extreme positions to the problem of identity over time: G. W. Leibniz' essentialism and Derek Parfit's reductionism. A third alternative conception of personal identity is presented here, more appropriately named personal nonduality, which is based on Nishida Kitarō's conception of personal unity as nonrelative contradictory self-identity.

One of the main problems of personal identity is supposed to be how we relate to our bodies. A few philosophers endorse what is called a 'bodily criterion of personal identity': they say that we are our bodies, or at any rate that our identity over time consists in the identity of our bodies. Many more deny this--typically on the grounds that we can imagine ourselves coming apart from our bodies. But both sides agree that the bodily criterion is an important view which anyone thinking about personal identity must consider.

This thesis gives an overview of the topic of personal identity from a philosophical viewpoint, describing both numerical and qualitative aspects. Reductionist approaches to numerical identity, such as the neo-Lockean psychological continuity theory of Derek Parfit or the physical criterion theory of Bernard Williams, are subject to a discussion. Apart from some significant criticisms in detail, there is the more general problem that they appear to imply a kind of neo-dualism. As a consequence, the author suggests a holistic approach to numerical personal identity which is more in accord with our times, placing the body firmly at the center of focus. The section on qualitative identity aims to develop a more complex theory of psychological continuity and continuity per se than that generally found in the literature. The suggestion is made that the most viable way to bring together the various strands of personal identity, both numerical and qualitative, is a concept of narrativity. Narratives are both indicative of and constitutive of personal identity.
