in addition to the references in the text to contemporary philosophers, the views I have expressed are indebted to the work of particular philosophers, especially in two cases: the argument of chapter 5 owes substantially to Derek Parfit, and that of chapter 6 owes to David K. Lewis. I have listed all contemporary sources in the order of their relevance to the text.
