T 3.1.1.15

As to those judgments which are the effects of our actions, and which, when false, give occasion to pronounce the actions contrary to truth and reason; we may observe, that our actions never cause any judgment, either true or false, in ourselves, and that 'tis only on others they have such an influence. 'Tis certain, that an action, on many occasions, may give rise to false conclusions in others; and that a person, who thro' a window sees any lewd behaviour of mine with my neighbour's wife, may be so simple as to imagine she is certainly my own. In this respect my action resembles somewhat a lye or falshood; only with this difference, which is material, that I perform not the action with any intention of giving rise to a false judgment in another, but merely to satisfy my lust and passion. It causes, however, a mistake and false judgment by accident; and the falshood of its effects may be ascribed, by some odd figurative way of speaking, to the action itself. But still I can see no pretext of reason for asserting, that the tendency to cause such an error is the first spring or original source of all immorality[68].
