Friendship and other intimate relationships have created difficulties for moral philosophers. While morality seems to require us to remain impartial between persons, friendship seems to generate demands or obligations of partiality toward our intimates. But the difficulty can be removed once we cease to focus on categorizing reasons as moral or non-moral. This tendency to divide reasons into categories of moral vs. non-moral leads us to give those that we label ‘moral’ pride of place and to assume that the category must be uniform. If we abandon these assumptions, then reasons of intimacy or friendship will no longer be so puzzling. We will then be able to see that all reasons, in the end, are importantly egocentric, and that deliberation must always proceed from an egocentric perspective.

In this thesis I will defend a Reductionist criterion of personal identity, and show that that criterion supports certain commonsense claims about the morality and rationality of special concern and about the morality of the distribution of goods among persons. ;In Chapter 1 , I will introduce the problem of personal identity across time. We will see that a plausible theory of personal identity supports and motivates the commonsense claim that we should be specially concerned about our future selves and intimates. ;In Chapter 2 , I will argue that we should reject a Non-Reductionist theory of personal identity. Non-Reductionism is unable to provide a coherent account of why persons persist through certain changes and not others, thereby committing us to a general skepticism about personal identity. Therefore, we should conclude that persons are not separately existing entities. ;In Chapter 3 , I present certain cases that suggest that we should reject our initial intuition that persons can swap bodies. I then consider whether we should accept the claim that it is not our identity that matters in our survival, and suggest that Reductionists can continue to claim that identity matters. ;In Chapter 4 , I defend the commonsense view of special concern. I claim that this commonsense view can be motivated and supported by the plausible Reductionist criteria discussed in Chapter 3. I show that the commonsense conception is more plausible than the Impersonalist view that tries to ground special concern in terms of impersonal values. ;In Chapter 5 , I show that Parfit's view of personal identity and what matters actually supports a moral theory in which the relationships in which persons stand to one another have intrinsic significance, rather than supporting the person-neutral theory of Utilitarianism
