Being alive throughout all history need not save you from dying, even if history extends infinitely into the past and future. Infinitely-long lives can fall short of genuine immortality and suffer all an ordinary mortal’s diminution in experience. Adapting David Lewis on time travel, Roy Sorensen imagines quasi-immortal ‘spore gods’, whose finite personal lives are distributed across infinite external time. While criticising the ‘Eleatic’ terms in which Sorensen presents spore gods, this paper argues his essential claims are correct: ‘spore god’ (...) worlds are logically and metaphysically possible. Indeed, going beyond Sorensen, spore gods are even nomologically accessible within General Relativity. (shrink)

Lucretius argues that death does not harm the person who dies. Harm could occur only if a person’s future non-existence were harmful. But one’s future non-existence is no more harmful than one’s non-existence before birth. Since a person is not harmed by lacking existence before birth, one is not harmed by lacking existence after dying.

In this essay I consider the argument that Bernard Williams advances in ‘The Makropolus Case’ for the meaninglessness of immortality. I also consider various counter-arguments. I suggest that the more clearly these counter-arguments are targeted at the spirit of Williams's argument, rather than at its letter, the less clearly they pose a threat to it. I then turn to Nietzsche, whose views about the eternal recurrence might appear to make him an opponent of Williams. I argue that, properly interpreted, these (...) views in fact make him an ally.

Personal time, as opposed to external time, has a certain role to play in the correct account of death and immortality. But saying exactly what that role is, and what role remains for external time, is not straightforward. I formulate and defend accounts of death and immortality that specify these roles precisely.

The standard definition of an instantaneous temporal part cannot properly deal with cases involving time travel. This paper provides a new definition of an instantaneous temporal part by appealing to David Lewis's distinction between external time and personal time. The new definition avoids the problems because it does not allow more than one instantaneous temporal part of an object at each moment of its personal time. We argue that this new definition, combined with our new perdurantist semantic thesis, deals with (...) cases of time travel successfully. (shrink)
