Many economic problems are also ethical problems: should we value economic equality? how much should we care about preserving the environment? how should medical resources be divided between saving life and enhancing life? This book examines some of the practical issues that lie between economics and ethics, and shows how utility theory can contribute to ethics. John Broome's work has, unusually, combined sophisticated economic and philosophical expertise, and Ethics Out of Economics brings together some of his most important essays, augmented with an updated introduction. The first group of essays deals with the relation between preference and value, the second with various questions about the formal structure of good, and the concluding section with the value of life. This work is of interest and importance for both economists and philosophers, and shows powerfully how economic methods can contribute to moral philosophy.

ABSTRACT Philosophers often do not make as sharp a distinction as they should between rationality and normativity. Partly this is because the word ‘reason’ can be used to refer to either, and this leads to a confusion over meanings. This paper starts by clarifying the meanings of ‘normativity’ and ‘rationality’. It argues that it is a conceptual truth that rationality supervenes on the mind. Then it considers substantive arguments that purport to show there is no real distinction between rationality and normativity. Many philosophers give a reductive account of rationality in terms of reasons. In particular, many claim that rationality consists in responding correctly to reasons. Since responding correctly to reasons is the concern of normativity, this in effect identifies rationality with normativity. This paper denies that rationality is identical to normativity, by means of what I call a ‘quick objection’. The quick objection is that rationality supervenes on the mind whereas complying with normativity does not. I consider and reject some ways of responding to the quick objection, including an argument by Kiesewetter to the effect that normativity supervenes on the mind and one by Lord to the effect that rationality does not. I also consider a different, Kantian argument to the effect that rationality does not supervene on the mind.

Abstract:Standard lessons from economics tell us that an externality creates inefficiency, and that this inefficiency can be removed by internalizing the externality. This papers considers how successfully these lessons can be extended to intergenerational externalities such as emissions of greenhouse gas. For intergenerational externalities, the standard lessons involve comparisons between states whose populations of people differ, either in their identities or their numbers. Common notions of efficiency break down in these comparisons. This paper supplies a new notion of efficiency that allows the lessons to survive, but at the cost of reducing their practical significance.

In The Moral Dimension, Amitai Etzioni claims, as did Albert Hirschman in Morality and the Social Sciences, that people often act from moral motives, that economics needs to recognize this, and that it will be significantly changed by doing so. I agree, though I think the changes may be smaller than Etzioni believes – I shall be explaining why. But Etzioni goes further. He makes a specific claim about the sort of morality that motivates people: it is deontological. In this paper, I shall examine what this means, how far it is true, and what difference it makes

This volume is a selection of Broome's recent papers on normativity, rationality, and reasoning. It covers a variety of topics such as the meanings of 'ought', 'reason', and 'reasons'; the fundamental structure of normativity and the metaphysical priority of ought over reasons; the ownership - or agent-relativity - of oughts and reasons; the distinction between rationality and normativity; the notion of rational motivation; what characterizes the human activity of reasoning, and what is the role of normativity within it; the nature of preferences and of reasoning with preferences; and others. These papers extend the work presented in his book Rationality Through Reasoning but there is little overlap between their content and the book's. They develop further some themes and arguments from the book, and answer some questions that the book left unanswered.
