Marya Schechtman argues that psychological continuity accounts of personal identity, as represented by Derek Parfit's account, fail to escape the circularity objection. She claims that Parfit's deployment of quasi-memory (and other quasi-psychological) states to escape circularity implicitly commit us to an implausible view of human psychology. Schechtman suggests that what is lacking here is a coherence condition, and that this is something essential in any account of personal identity. In response to this I argue first that circularity may be escaped using quasi-psychological states even with the addition of the coherence condition. Second, I argue that there is something right about the coherence condition, and a major task of this paper is to identify its proper theoretical role. I do so by reflection on integration therapies for people with multiple personality disorder (MPD). The familiar distinction between the moral and the metaphysical concept of the person is developed alongside such reflection. Connecting these two issues I argue that coherence acts as a normative constraint on accounts of personal identity, but that the normative dimension of personhood is not essential to our notion of a person tout court.

Bishop Butler objected to Locke's theory of personal identity on the grounds that memory presupposes personal identity. Most of those sympathetic with Locke's account have accepted Butler's criticism, and have sought to devise a theory of personal identity in the spirit of Locke's that avoids Butler's circularity objection. John McDowell has argued that even the more recent accounts of personal identity are vulnerable to the kind of objection Butler raised against Locke's own account. I criticize McDowell's stance, drawing on a distinction introduced by Annalisa Coliva between two types of immunity to error through misidentification.

Does intention presuppose personal identity, and what relevance does the issue have for the contemporary personal identity debate? I distinguish three ways in which intention might be said to presuppose personal identity, focusing mainly on causal presupposition and content presupposition. I argue that intention often causally presupposes personal identity. I argue that intention does not content-presuppose personal identity. The former result is a potential basis for a Butlerian circularity objection to Lockean theories of personal identity. The latter result undercuts a prominent Lockean reply to ‘the thinking animal’ objection which has recently supplanted traditional Butlerian circularity objections in the personal identity debate.

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.
