Henry Sidgwick held that ethics focuses on the reasons people use in deciding between two courses of action and that the study of ethics is the attempt to bring these reasons together in a coherent system. Modern Western people use three different “methods” of ethics; that is, three different ways of answering the question, “Why should I do such and such?” They may reason with a view to self-interest; they may ask what their duty is; they may try to estimate the effect of the action in question on the general well-being. Sidgwick held that ordinary people do not find it necessary to choose between these methods: On some occasions they use one, and on other occasions another.

Professed moralists, however, have condemned this slackness and have insisted that all ethical reasoning should proceed from one principle and employ one method. Some have maintained that ethics is the reasoned pursuit of happiness, whether one’s own or that of all humankind. Others have denied this and maintained that human reason knows immediately what acts are right and what are wrong. In Sidgwick’s view, neither of these approaches could be carried through consistently without unduly constraining the moral intention of ordinary people. He accepted the ideal of unity and consistency that governs all theoretical inquiry; but he was wary of Procrustean solutions, and thought it better to leave certain questions unresolved than to do violence to important aspects of moral...

Egotistical Hedonism

(Student Guide to World Philosophy)

The first method discussed by Sidgwick is egoistical hedonism. Sidgwick aimed to separate ethical questions from psychological ones; however, historically, ethical hedonism has always been closely connected with psychological hedonism and has been thought to draw support from it. For example, Jeremy Bentham maintained that “the constantly proper end of action on the part of any individual” is his own happiness. This is an ethical proposition. However, Bentham also said that “on the occasion of every act he exercises, every human being is inevitably led to pursue that line of conduct which, according to his view of the case, taken by him at the moment, will be in the highest degree contributory to his own greatest happiness.” This is a psychological proposition. Sidgwick said that, if the psychological statement be construed strictly, the ethical statement is meaningless: There is no point in maintaining that one “ought” to pursue the line of conduct that will bring one the greatest happiness if one is incapable of following any other line. However, even if the psychological law is taken in a weak and approximative sense, “there is no necessary connection between the psychological proposition that pleasure or absence of pain to myself is always the actual ultimate end of my action, and the ethical proposition that my own greatest happiness or pleasure is for me the right ultimate end.”

Ethical hedonism does, however, deserve...

Common morality, however, although it allows a place for reasonable self-love, does not admit that people have the right to live for themselves alone. This leads to the second “method” of ethics, which Sidgwick called intuitionism. From this point of view, right conduct has very little to do with desires and selfish enjoyment; what matters is duty and virtue.

Sidgwick held that the notions of “right” and “ought,” which are fundamental to the intuitionist point of view are “too elementary to admit of any formal definition.” They cannot be derived from the idea of the good, if this is understood to consist of happiness. If, on the other hand, it is understood to consist of excellence, this is merely another way of referring to what ought to be. The judgment that a certain course of action is right presents itself as a direct cognition. It may be accompanied by feelings, such as sympathy or benevolence, but it is itself a dictate of reason. Unlike egoistic hedonism, which reasons a posteriori in its effort to estimate future good, the ethics of right and duty employs an a priori method, reasoning from self-evident truth. Sidgwick called it, therefore, the method of intuition.

Sidgwick maintained, however, that it is one thing to recognize the prima facie claims of moral insight—that they are simple and categorical—and something else to grant that their claims are veridical. The point he wished to make is that people would not have the notions of morally right and wrong (as distinct from instrumentally right and wrong and logically right and wrong) except for some kind of direct moral insight.

The systematic moralist soon discovers that not all moral intuitions are trustworthy. There are, said Sidgwick, three levels on which the claims of obligation present themselves to the conscience. First, there is the kind of judgment ordinarily referred to as the voice of conscience, which functions after the analogy of sense perception and testifies to the rightness or wrongness of single acts or motives. However, the slightest experience with others is enough to convince people that conscience, in the sense of an intuitive perception, is not infallible. Virtuous people differ in their judgment of a course of action. In their effort to persuade one another, they appeal from the particular instance to general rules that seem to be self-evident. This is the second level of intuitive moral reasoning. It is made up of rules such as these: that we govern our passions, obey laws, honor parents, and keep promises.

To the unreflective mind, these rules seem unexceptionable. Nevertheless, a serious attempt to give them precise meaning and application discloses at once their ambiguity. For example, it is said to be intuitively certain that promisers are bound to perform what both they and the promisees understood to be undertaken. On examination, however, all sorts of qualifications come into view, which are...

Sidgwick’s discussion of utilitarianism, the third of his three “methods,” is brief. It need not be extensive because its main principles have already been stated—that the good is pleasure was shown under egoism and that the right action has regard to the happiness of the whole was shown under intuitionism. Sidgwick does not try to base our duty to humankind at large on “feelings of benevolence,” or “natural sympathy.” It rests on a moral cognition. Sidgwick declared that utilitarianism requires people to sacrifice not only their private happiness but also that of persons whose interests natural sympathy makes far dearer to them than their own well-being. Its demands are sterner and more rigid than traditional notions of duty and virtue.

The fact that he found the rationale of utilitarianism implicit in the axioms of intuitionism was, for Sidgwick, a great step toward bringing the diverse methods of ethics into a higher synthesis. That egoism finds its rule of prudence among them was also encouraging. However, one fundamental breach remained to be healed: how to reconcile egoism with utilitarian duty.

Theologians have resolved the problem by the doctrine of immortality and eternal rewards, but Sidgwick refused that solution in the interests of preserving the autonomy of ethics. He did not deny the desirability of such an arrangement, but he saw no rational evidence for it. “It only expresses the vital need that our Practical Reason feels of proving or postulating this connection of virtue and self-interest, if it is to be made consistent with itself. For the negation of this connection must force us to admit an ultimate and fundamental contradiction in our apparent intuitions of what is Reasonable in conduct.”

That would be tantamount to admitting that rational ethics is an illusion. It would not mean abandoning morality, “but it would seem to be necessary to abandon the idea of rationalizing it completely.” This, in turn, would have the practical consequence that in a conflict between duty and self-interest, the conflict would be decided by “the preponderance of one or other of two groups of non-rational impulses.”

Sidgwick’s conclusion has about it the inconclusiveness of many a Socratic dialogue. He suggested that we may be faced with the alternative of accepting moral propositions “on no other grounds than that we have a strong disposition to accept them,” or of “opening the door to universal scepticism.”
