For as the very essence of morality is supposed to consist in an agreement or disagreement to reason, the other circumstances are entirely arbitrary, and can never either bestow on any action the character of virtuous or vicious, or deprive it of that character. To which we may add, that this agreement or disagreement, not admitting of degrees, all virtues and vices would of course be equal. Should it be pretended, that though a mistake of _fact_ be not criminal, yet a mistake of _right_ often is; and that this may be the source of immorality: I would answer, that 'tis impossible such a mistake can ever be the original source of immorality, since it supposes a real right and wrong; that is, a real distinction in morals, independent of these judgments. A mistake, therefore, of right, may become a species of immorality; but 'tis only a secondary one, and is founded on some other antecedent to it. 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, through 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 lie or falsehood; 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 falsehood 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.[2] Thus, upon the whole, 'tis impossible that the distinction betwixt moral good and evil can be made by reason; since that distinction has an influence upon our actions, of which reason alone is incapable. Reason and judgment may, indeed, be the mediate cause of an action, by prompting or by directing a passion; but it is not pretended that a judgment of this kind, either in its truth or falsehood, is attended with virtue or vise. And as to the judgments, which are caused by our judgments, they can still less bestow those moral qualities on the actions which are their causes. But, to be more particular, and to show that those eternal immutable fitnesses and unfitnesses of things cannot be defended by sound philosophy, we may weigh the following considerations.
