In The Methods of Ethics, Sidgwick took seriously egoism, utilitarianism, and commonsense morality. Virtue ethics was treated as part of commonsense morality. Three Methods, reflecting recent tastes, considers Kant, consequentialism, and virtue ethics. Oddly, it does not reflect the major development since Sidgwick—the revival of contractualism.

Granted that desire is always present in the genesis of human action, is it something on the presence of which the agent always reflects? I may act on a belief without coming to recognize that I have the belief. Can I act on a desire without recognizing that I have the desire? In particular, can the desire have a motivational presence in my decision making, figuring in the background, as it were, without appearing in the content of my deliberation, in (...) the foreground? We argue, perhaps unsurprisingly, that yes, desire can figure in the background without figuring in the foreground: we call this the strict background view of desire. But we then show, and this is where the surprise comes, that the strict background view of desire has significant implications for contemporary moral philosophy. (shrink)

It turned out that there was no phlogiston, no caloric fluid, and no luminiferous ether. Might it turn out that there are no beliefs and desires? Patricia and Paul Churchland say yes} We say no. In part one we give our positive argument for the existence of beliefs and desires.

In general, the technical apparatus of decision theory is well developed. It has loads of theorems, and they can be proved from axioms. Many of the theorems are interesting, and useful both from a philosophical and a practical perspective. But decision theory does not have a well agreed upon interpretation. Its technical terms, in particular, ‘utility’ and ‘preference’ do not have a single clear and uncontroversial meaning. How to interpret these terms depends, of course, on what purposes in pursuit of (...) which one wants to put decision theory to use. One might want to use it as a model of economic decision-making, in order to predict the behavior of corporations or of the stock market. In that case, it might be useful to interpret the technical term ‘utility’ as meaning money profit. Decision theory would then be an empirical theory. I want to look into the question of what ‘utility’ could mean, if we want decision theory to function as a theory of practical rationality. I want to know whether it makes good sense to think of practical rationality as fully or even partly accounted for by decision theory. I shall lay my cards on the table: I hope it does make good sense to think of it that way. For, I think, if Humeans are right about practical rationality, then decision theory must play a very large part in their account. And I think Humeanism has very strong attractions. (shrink)

I wish more books of philosophy were like this one. It is elegantly written. It is filled with provocative claims and ingenious arguments. It is a really good read, even while it forces us to rethink many of our assumptions about practical reason and practical reasoning, morality and agency.

This study uses techniques from economics to illuminate fundamental questions in ethics, particularly in the foundations of utilitarianism. Topics considered include the nature of teleological ethics, the foundations of decision theory, the value of equality and the moral significance of a person's continuing identity through time.
