《道德原则研究·第一章·道德的一般原则》第4节
But though this question, concerning the general principles of morals, be curious and important, it is needless for us, at present, to employ farther care in our researches concerning it. For if we can be so happy, in the course of this enquiry, as to discover the true origin of morals, it will then easily appear how far either sentiment or reason enters into all determinations of this nature . In order to attain this purpose, we shall endeavour to follow a very simple method: we shall analyse that complication of mental qualities, which form what, in common life, we call Personal Merit: we shall consider every attribute of the mind, which renders a man an object either of esteem and affection, or of hatred and contempt; every habit or sentiment or faculty, which, if ascribed to any person, implies either praise or blame, and may enter into any panegyric or satire of his character and manners. The quick sensibility, which, on this head, is so universal among mankind, gives a philosopher sufficient assurance, that he can never be considerably mistaken in framing the catalogue, or incur any danger of misplacing the objects of his contemplation: he needs only enter into his own breast for a moment, and consider whether or not he should desire to have this or that quality ascribed to him, and whether such or such an imputation would proceed from a friend or an enemy. The very nature of language guides us almost infallibly in forming a judgement of this nature; and as every tongue possesses one set of words which are taken in a good sense, and another in the opposite, the least acquaintance with the idiom suffices, without any reasoning, to direct us in collecting and arranging the estimable or blameable qualities of men. The only object of reasoning is to discover the circumstances on both sides, which are common to these qualities; to observe that particular in which the estimable qualities agree on the one hand, and the blameable on the other; and thence to reach the foundation of ethics, and find those universal principles, from which all censure or approbation is ultimately derived. As this is a question of fact, not of abstract science, we can only expect success, by following the experimental method, and deducing general maxims from a comparison of particular instances. The other scientific method, where a general abstract principle is first established, and is afterwards branched out into a variety of inferences and conclusions, may be more perfect in itself, but suits less the imperfection of human nature, and is a common source of illusion and mistake in this as well as in other subjects. Men are now cured of their passion for hypotheses and systems in natural philosophy, and will hearken to no arguments but those which are derived from experience. It is full time they should attempt a like reformation in all moral disquisitions; and reject every system of ethics, however subtle or ingenious, which is not founded on fact and observation. We shall begin our enquiry on this head by the consideration of the social virtues, Benevolence and Justice. The explication of them will probably give us an opening by which the others may be accounted for.

休谟在这段话里做了一个决定全书走向的方法论宣告。此前他刚刚铺陈了两方的论据：道德究竟是来自理性推演还是来自情感感受，双方各有说得通的地方，他本人也倾向于认为两者实际上协同作用。但他说，此时再纠缠这个"一般原则"的争论没有必要。为什么？因为他打算换一条路走——不是在抽象层面继续辩理性和情感谁主谁从，而是先找出道德的真正根源在哪里，一旦找到，理性和情感各自介入…
