《道德原则研究·第三章·论正义》第15节
[休谟自注] It is evident, that the will or consent alone never transfers property, nor causes the obligation of a promise (for the same reasoning extends to both), but the will must be expressed by words or signs, in order to impose a tie upon any man. The expression being once brought in as subservient to the will, soon becomes the principal part of the promise; nor will a man be less bound by his word, though he secretly give a different direction to his intention, and withhold the assent of his mind. But though the expression makes, on most occasions, the whole of the promise, yet it does not always so; and one who should make use of any expression, of which he knows not the meaning, and which he uses without any sense of the consequences, would not certainly be bound by it. Nay, though he know its meaning, yet if he use it in jest only, and with such signs as evidently show, that he has no serious intention of binding himself, he would not lie under any obligation of performance; but it is necessary, that the words be a perfect expression of the will, without any contrary signs. Nay, even this we must not carry so far as to imagine, that one, whom, by our quickness of understanding, we conjecture, from certain signs, to have an intention of deceiving us, is not bound by his expression or verbal promise, if we accept of it; but must limit this conclusion to those cases where the signs are of a different nature from those of deceit. All these contradictions are easily accounted for, if justice arise entirely from its usefulness to society; but will never be explained on any other hypothesis. It is remarkable that the moral decisions of the jesuits and other relaxed casuists, were commonly formed in prosecution of some such subtilties of reasoning as are here pointed out, and proceed as much from the habit of scholastic refinement as from any corruption of the heart, if we may follow the authority of Mons. Bayle. See his Dictionary, article Loyola. And why has the indignation of mankind risen so high against these casuists; but because every one perceived, that human society could not subsist were such practices authorized, and that morals must always be handled with a view to public interest, more than philosophical regularity? If the secret direction of the intention, said every man of sense, could invalidate a contract; where is our security? And yet a metaphysical schoolman might think, that, where an intention was supposed to be requisite, if that intention really had not place, no consequence ought to follow, and no obligation be imposed. The casuistical subtilties may not be greater than the snbtilties of lawyers, hinted at above; but as the former are pernicious, and the latter innocent and even necessary, this is the reason of the very different reception they meet with from the world. It is a doctrine of the Church of Rome, that the priest, by a secret direction of his intention, can invalidate any sacrament. This position is derived from a strict and regular prosecution of the obvious truth, that empty words alone, without any meaning or intention in the speaker, can never be attended with any effect. If the same conclusion be not admitted in reasonings concerning civil contracts, where the affair is allowed to be of so much less consequence than the eternal salvation of thousands, it proceeds entirely from men's sense of the danger and inconvenience of the doctrine in the former case: And we may thence observe, that however positive, arrogant, and dogmatical any superstition may appear, it never can convey any thorough persuasion of the reality of its objects, or put them, in any degree, on a balance with the common incidents of life, which we learn from daily observation and experimental reasoning.
注释摘要
休谟在这个自注里处理的，是一个会直接动摇他整套正义学说的难题。如果正义与财产义务的根基全在社会效用，那么承诺——这个支撑一切契约与交换的基石——的力量究竟从何而来？有人会说：来自意志，来自内心的同意。休谟的回答锋利而曲折，他从“表面看是这样”一路推到“其实完全不是”，而且每一步都在检验一个标准：社会还能不能运转。 他的论证分三层推进。第一层，他认为纯粹的内…
