Psychological Sequentialism holds that no causal constraint is necessary for the preservation of what matters in survival; rather, it is sufficient for preservation if two groups of mental states are similar enough and temporally close enough. Suppose that one’s body is instantaneously dematerialized and subsequently, by an amazing coincidence, a collection of molecules is configured to form a qualitatively identical human body. According to Psychological Sequentialism, these events preserve what matters in survival. In this article, I examine some of the (...) main arguments for the view and argue that they fail to establish that no causal constraint is necessary. I also argue that Psychological Sequentialism yields implausible consequences that render it hard to accept the view. (shrink)

This paper is a defence of a psychological view of personal identity against the attack Peter Unger launches against it in his Identity, Consciousness and Value. Unger attempts to undermine the traditional support which a psychological criterion of identity has drawn from thought-experiments, and to show that such a criterion has totally unacceptable implications -- in particular, that it allows that persons can go out of and come back into existence. I respond to both aspects of this criticism, arguing that (...) the relevant thought-experiments (and the support they appear to offer) survive Unger's attack intact, and that he does not establish his case against intermittent existence.

Among theories of personal identity over time the simple view has not been popular among philosophers, but it nevertheless remains the default view among non philosophers. It may be construed either as the view that nothing grounds a claim of personal identity over time, or that something quite simple (a soul perhaps) is the ground. If the former construal is accepted, a conspicuous difficulty is that the condition of causal dependence between person-stages is absent. But this leaves such a view (...) open to an objection from the failure to provide a condition of individuation. If, on the other hand something like a soul is said to ground personal identity over time, such an account turns out to be more suited to a kind of continuity view. (shrink)

Traditionally, this puzzle has been solved in various ways. Aristotle, for example, distinguished between “accidental” and “essential” changes. Accidental changes are ones that don't result in a change in an objects' identity after the change, such as when a house is painted, or one's hair turns gray, etc. Aristotle thought of these as changes in the accidental properties of a thing. Essential changes, by contrast, are those which don't preserve the identity of the object when it changes, such as when (...) a house burns to the ground and becomes ashes, or when someone dies. Armed with these distinctions, Aristotle would then say that, in the case of accidental changes, (1) and (2) are both false—a changing thing can really change one of its “accidental properties” and yet literally remain one and the same thing before and after the change.

In this article, I develop and defend a conception of psychological continuity that differs from the 'orthodox' conception in terms of overlapping chains of strongly connected mental states. By recognizing the importance of the (narrative) interrelatedness of qualitatively dissimilar mental contents, as well as the role of the body in psychological continuity, I argue, serious problems confronting the orthodox view can be solved.
