Adapted fromUtilitarianismby John Stewart Mill (1863)

Only while the world is in a very imperfect state can it happen that anyone’s best chance of serving the happiness of others is through the absolute sacrifice of his own happiness; but while the world is in that imperfect state, I fully admit that the readiness to make such a sacrifice is the highest virtue that can be found in man. I would add something that may seem paradoxical: namely that in this present imperfect condition of the world, the conscious ability to do without happiness gives the best prospect of bringing about such happiness as is attainable. For nothing except that consciousness can raise a person above the chances of life by making him feel that fate and fortune—let them do their worst!—have no power to subdue him. Once he feels that, it frees him from excessive anxiety about the evils of life and lets him (like many a stoic in the worst times of the Roman empire) calmly develop the sources of satisfaction that are available to him, not concerning himself with the uncertainty regarding how long they will last or the certainty that they will end.

Meanwhile, let utilitarians never cease to claim that they have as much right as the stoic or the transcendentalist to maintain the morality of devotion to a cause as something that belongs to them. The utilitarian morality does recognize that human beings can sacrifice their own greatest good for the good of others; it merely refuses to admit that the sacrifice is itself a good. It regards as wasted any sacrifice that doesn’t increase, or tend to increase, the sum total of happiness. The only self-renunciation that it applauds is devotion to the happiness, or to some of the means to happiness, of others. . . . I must again repeat something that the opponents of utilitarianism are seldom fair enough to admit, namely that the happiness that forms the utilitarian standard of what is right in conduct is not the agent’s own happiness but that of all concerned. As between his own happiness and that of others, utilitarianism requires him to be as strictly impartial as a disinterested and benevolent spectator. In the golden rule of Jesus of Nazareth we read the complete spirit of the ethics of utility. To do as you would be done by, and to love your neighbor as yourself constitute the ideal perfection of utilitarian morality.

实际的方式尽可能to this ideal, the ethics of utility would command two things. (1) First, laws and social arrangements should place the happiness (or what for practical purposes we may call the interest) of every individual as much as possible in harmony with the interest of the whole. (2) Education and opinion, which have such a vast power over human character, should use that power to establish in the mind of every individual an unbreakable link between his own happiness and the good of the whole; especially between his own happiness and the kinds of conduct (whether doing or allowing) that are conducive to universal happiness. If (2) is done properly, it will tend to have two results: (2a) The individual won’t be able to conceive the possibility of being personally happy while acting in ways opposed to the general good. (2b) In each individual a direct impulse to promote the general good will be one of the habitual motives of action, and the feelings connected with it will fill a large and prominent place in his sentient existence. This is the true character of the utilitarian morality. If those who attack utilitarianism see it as being like this, I don’t know what good features of some other moralities they could possibly say that utilitarianism lacks, what more beautiful or more elevated developments of human nature any other ethical systems can be supposed to encourage, or what motivations for action that aren’t available to the utilitarian those other systems rely on for giving effect to their mandates.
