WHEN, IF EVER, DO WE AGGREGATE? AND WHY?

Abstract

Aggregation in moral philosophy calls for the summing or averaging of values or utilities as a guide to individual behavior. But morality, it is argued, needs to be individualistic, in view of the evident separateness of persons, especially given the great disparities among individuals who nevertheless interact with each other in social life. The most plausible general moral program is the classical liberal (or “libertarian”) one calling for mutual noninterference rather than treating others as equal to oneself in point of demands on our action. Why, then, would we ever aggregate? The reason is that we are affected by behavior that has general effects, especially unintended side effects, on all sorts of people among whom we ourselves are often to be found. When we are randomly situated among such groups—as we sometimes are and often are not—minimizing aggregate harm is the plausible strategy, and sometimes promoting aggregate benefit as well.

1 The title of Hardin, Russell's book is Morality within the Limits of Reason (Chicago: University of Chicago Press, 1988)Google Scholar. Much of the book is concerned with utilitarianism, philosophical treatment of which has suffered due to the assumption that we know most of the things utilitarianism appears to require that we know, such as how to measure welfare (or, indeed, just what welfare is) and how to determine what the social effects of one's actions actually are. (See ibid., xv–xx.) Hardin plausibly dubs me a “backsliding utilitarian” (privately); I hope, however, that it is nearer to the truth that I am a libertarian, downing, where appropriate, what comes close enough to being a dose of utilitarianism.

See also ibid., 38 n. 9: “A maxim is the subjective principle of acting and must be distinguished from the objective principle, i.e., the practical law…. [which is] the objective principle valid for every rational being, and the principle by which it ought to act, i.e., an imperative.”

18 At least one of Kant's translators uses the term ‘virtue’ to refer to the set of moral directives that are of “broad” rather than “strict” obligation: Ellington, Jamestranslates the second part of Kant's Tugendlehre as The Metaphysical Principles of Virtue (Indianapolis, IN: Bobbs-Merrill, 1961)Google Scholar. But that is a different distinction from the one intended here.
