Economic concepts and methods are used to throw light on some aspects of common-sense ethics and the difference between it and Utilitarianism. (1) Very few exceptions are allowed to the rules of common-sense ethics, because of the cost of information required to justify an exception to Conscience and to other people. No such stringency characterizes Utilitarianism, an abstract system constructed by philosophers. (2) Rule Utilitarianism is neither consistent with common-sense ethics, nor does it maximize utility as has been claimed for it. The same is true of more recent variants of Utilitarianism. (3) Second best and first best are usually identical in common-sense ethics. They are often identical in Utilitarianism when a moral situation can be represented by a Prisoner's Dilemma. However, problems arise in permissive forms of Utilitarianism when it is not obvious that second best should be applied.

In the large recent literature on the nature of human persons, persons are usually studied in isolation from the world in which they live. What persons are most fundamentally, philosophers say, are human animals, or brains, or perhaps souls -- without any consideration of the social and physical environments without which persons would not exist. In this article, I want to compensate for such overly narrow focus. Instead of beginning with the nature of persons cut off from any environment, I shall begin with metaphysical consideration of the world of which persons are a part. I shall then briefly describe my view of persons, according to which persons are material objects like other concrete things in the world, but are unique in their first-person perspectives. Finally, I shall consider some of the special relations that persons, and only persons, have to other things in the world.

Richard Henson has argued that hedonistic-average-act-utilitarianism has the extremely counter-intuitive consequence that certain individuals ought to be killed simply because they are unhappy and because their deaths would raise the average level of happiness. It is argued that Henson's criticisms are correct and that they can be extended to other versions of utilitarianism: total (as opposed to average) utilitarianism, non-hedonistic versions of utilitarianism, and those versions of act-utilitarianism that have originated in the recent controversy about population control.

The two dominant contemporary moral theories, Kantianism and utilitarianism, have difficulty accommodating our commonsense understanding of friendship as a relationship with significant moral implications. The difficulty seems to arise from their underlying commitment to impartiality, to the claim that all persons are equally worthy of concern. Aristotelian accounts of friendship are partialist in so far as they defend certain types of friendship by appeal to the claim that some persons, the virtuous, are in fact more worthy of concern than are other persons. This article argues that we can preserve the underlying impartiality of Kantianism and utilitarianism, while also preserving a certain partiality with respect to our friends: the partiality of commonsense only seems objectionable if we fail to understand the true grounds, nature, and implications of such partiality. Neo-Aristotelian partiality should be rejected in favor of commonsense partiality.

Ethical theories must include an account of the concept of a person. They also need a criterion of personal identity over time. This requirement is most needed in theories involving distributions of resources or questions of moral responsibility. For instance, in using ethical theories involving compensations of burdens, we must be able to keep track of the identities of persons earlier burdened in order to ensure that they are the same people who now are to receive the compensatory benefits. Similarly, in order to attribute moral responsibility to someone for an act, we must be able to determine that that person is the same person as the person who performed the act. Unfortunately, ethical theories generally include a concept of a person and criteria of personal identity either as notions implied or presupposed by the already worked out theory, with little or no argument given in support of them. But both approaches are unsatisfactory, for each runs the risk of ignoring certain fundamental features of the way persons actually are. What is needed first is a plausible metaphysical account of persons and personal identity to which an ethical theory might then conform and apply. Derek Parfit has attempted to provide such an account in Reasons and Persons, where he argues for what he calls the reductionist view of persons and personal identity and then attempts to show how such a conception provides a metaphysical background that lends important partial support to utilitarianism. 1 But Parfit’s metaphysical view is neutral between two possible conceptions of personhood, and utilitarianism presupposes the truth of the more radical of the two conceptions, which precludes the possibility of there being a class of goods crucial to any plausible ethical theory. Utilitarianism thus presupposes a wildly implausible conception of persons, and so is itself implausible.

This is a review of Utilitarianism and Empire edited by Schultz and Varouxakis. It expresses admiration for the volume, especially the essays by Pitts and Rosen.
