_General Uniformity._--We are by no means disposed to admit, however, that the diversity in men's moral judgments is so great, as might, at first, appear. There is, on the contrary, a general uniformity. As to the great essential principles of morals, men, after all, do judge much alike, in different ages and different countries. In details, they differ, in general principles, they agree. In the application of the rules of morality to particular actions, they differ widely, according to circumstances; in the recognition of the right and the wrong, as distinctive principles, and of obligation to do the right as known, and avoid the wrong as known, in this they agree. It must be remembered, moreover, that men do not always act according to their own ideas of right. From the general neglect of virtue, in any age or community, and the prevalence of great and revolting crimes, we cannot safely infer the absence, or even the perversion, of the moral faculty. _Precisely in what the Diversity consists._--It is important to bear in mind, throughout this discussion, the distinction between the _idea_ of right, in itself considered, and the _perception_ of a given act as right; the one a simple conception, the other an act of judgment; the one an idea derived from the very constitution of the mind, connate, if not innate, the other an application of that idea, by the understanding, to particular instances of conduct. The former, the _idea_ of moral distinctions, may be universal, necessary, absolute, unerring; the latter, the _application_ of the idea to particular instances, and the decision that such and such acts are, or are not, right, may be altogether an incorrect and mistaken judgment. Now it is precisely at this point that the diversity in the moral judgments of mankind makes its appearance. In recognizing the distinction of right and wrong, they agree; in the application of the same to particular instances in deciding _what_ is right and _what_ is wrong--a simple act of the judgment, an exercise of the understanding, as we have seen--in this it is that they differ. And the difference is no greater, and no more inexplicable, with respect to this, than in any other class of judgments.
