Persons, interests, and justice

In our lives, we aim to achieve welfare for ourselves, that is, to live good lives. But we also have another, more impartial perspective, where we aim to balance our concern for our own welfare against a concern for the welfare of others. This is a perspective of justice. Nils Holtug examines these two perspectives and the relations between them.

The first part of the book is concerned with prudence; more precisely, with what the necessary and sufficient conditions are for having a self-interest in a particular benefit. It includes discussions of the extent to which self-interest depends on preferences, personal identity, and what matters in survival. It also considers the issue of whether it can benefit (or harm) a person to come into existence and what the implications are for our theory of self-interest. A 'prudential view' is defended, according to which a person has a present self-interest in a future benefit if and only if she stands in a relation of continuous physical realization of (appropriate) psychology to the beneficiary, where the strength of the self-interest depends both on the size of the benefit and on the strength of this relation.
