A traditional argument based on Leibniz’s Law concludes that, for example, a statue and the piece of marble of which it is made are two different objects. This is because they have different properties: the statue can survive the loss of some of its parts but the piece of marble cannot. Lynne Rudder Baker adds that the piece of marble constitutes the statue. In this paper I focus on what I think is the most powerful objection to Baker’s account of (...) the constitution relation, which has to do with her notion of circumstances. I present the objection following Derk Pereboom’s formulation and, afterwards, I analyse Baker’s answers to the criticism. I conclude that they make her overall project less attractive. Finally, I propose a new answer to the criticism. This will suppose a new formulation of the constitution relation, albeit done in the spirit of Baker’s account. (shrink)

Lynne Rudder Baker’s Constitution View of human persons has come under much recent scrutiny. Baker argues that each human person is constituted by, but not identical to, a human animal. Much of the critical discussion of Baker’s Constitution View has focused upon this aspect of her account. Less has been said about the positive diachronic account of personal identity offered by Baker. Baker argues that it is sameness of what she labels ‘first-person perspective’ that is essential to understanding personal identity (...) over time . Baker claims that her account avoids the commitment to indeterminacy of personal identity entailed by the psychological account. Further, the psychological account, but not her account, is plagued by what Baker labels the ‘duplication problem’. In the end, I argue that neither of these considerations forces us to renounce the psychological account and adopt Baker’s favored account. (shrink)
