《道德原则研究·第九章·结论》第6节
What more, therefore, can we ask to distinguish the sentiments, dependent on humanity, from those connected with any other passion, or to satisfy us, why the former are the origin of morals, not the latter? Whatever conduct gains my approbation, by touching my humanity, procures also the applause of all mankind, by affecting the same principle in them; but what serves my avarice or ambition pleases these passions in me alone, and affects not the avarice and ambition of the rest of mankind. There is no circumstance of conduct in any man, provided it have a beneficial tendency, that is not agreeable to my humanity, however remote the person; but every man, so far removed as neither to cross nor serve my avarice and ambition, is regarded as wholly indifferent by those passions. The distinction, therefore, between these species of sentiment being so great and evident, language must soon be moulded upon it, and must invent a peculiar set of terms, in order to express those universal sentiments of censure or approbation, which arise from humanity, or from views of general usefulness and its contrary. Virtue and Vice become then known; morals are recognized; certain general ideas are framed of human conduct and behaviour; such measures are expected from men in such situations. This action is determined to be conformable to our abstract rule; that other, contrary. And by such universal principles are the particular sentiments of self-love frequently controlled and limited. [休谟自注] It seems certain, both from reason and experience, that a rude, untaught savage regulates chiefly his love and hatred by the ideas of private utility and injury, and has but faint conceptions of a general rule or system of behaviour. The man who stands opposite to him in battle, he hates heartedly, not only for the present moment, which is almost unavoidable, but for ever after; nor is he satisfied without the most extreme punishment and vengeance. But we, accustomed to society, and to more enlarged reflections, consider, that this man is serving his own country and community; that any man, in the same situation, would do the same; that we ourselves, in like circumstances, observe a like conduct; that; in general, human society is best supported on such maxims: and by these suppositions and views, we correct, in some measure, our ruder and narrower positions. And though much of our friendship and enemity be still regulated by private considerations of benefit and harm, we pay, at least, this homage to general rules, which we are accustomed to respect, that we commonly perver our adversary's conduct, by imputing malice or injustice to him, in order to give vent to those passions, which arise from self-love and private interest. When the heart is full of rage, it never wants pretences of this nature; though sometimes as frivolous, as those from which Horace, being almost crushed by the fall of a tree, effects to accuse of parricide the first planter of it.
注释摘要
休谟在这一段里要做一件很确切的事：把「从人道出发的情感」与「从其他激情出发的情感」截然分开，并证明前者才是道德的起源。这一步之所以必要，是因为全书至此已经论证了个人价值全在于有用或令人愉快的品质，但还需要说明，人们在赞扬或谴责时，依据的究竟是什么情感官能，以及为什么是这个官能而不是别的。 他提出了一个功能性的区分标准。一种行为只要触动了我的「人道」，也就是…
