He adduces, as another illustration, what he deems the kindred emotion of Beauty. Our feeling of beauty is not the mere perception of forms and colours, or the discovery of the uses of certain combinations of forms; it is an emotion arising from these, indeed, bat distinct from them. Our feeling of moral excellence, in like manner, is not the mere perception of different actions, or the discovery of the physical good that these may produce; it is an emotion sui generis, superadded to them.
He adverts, in a strain of eloquent indignation, to the objection grounded on differences of men's moral judgment. There are philosophers, he exclaims, 'that can turn away from the conspiring chorus of the millions of mankind, in favour of the great truths of morals, to seek in some savage island, a few indistinct murmurs that may seem to be discordant with the total harmony of mankind.' He goes on to remark, however, that in our zeal for the immutability of moral distinctions, we may weaken the case by contending for too much; and proposes to consider the species of accordance that may be safely argued for.
He begins by purging away the realistic notion of Virtue, considered as a self-existing entity. He defines it—a term expressing the relation of certain actions to certain emotions in the minds contemplating them; its universality is merely co-extensive with these minds. He then concedes that all mankind do not, at every moment, feel precisely the same emotions in contemplating the same actions, and sets forth the limitations as follows;—
First, In moments of violent passion, the mind is incapacitated for perceiving moral differences; we must, in such cases appeal, as it were, from Philip drunk to Philip sober.
Secondly, Still more important is the limitation arising from the complexity of many actions. Where good and evil results are so blended that we cannot easily assign the preponderance, different men may form different conclusions. Partiality of views may arise from this cause, not merely in individuals, but in whole nations. The legal permission of theft in Sparta is a case in point. Theft, as theft, and without relation to the political object of inuring a warlike people, would have been condemned in Sparta, as well as with us. [The retort of Locke is not out of place here; an innate moral sentiment that permits a fundamental virtue to be set aside on the ground of mere state convenience, is of very little value.] He then goes on to ask whether men, in approving these exceptions to morality, approve them because they are immoral? [The opponents of a moral sense do not contend for an immoral sense.] Suicide is not commended because it deprives society of useful members, and gives sorrow to relations and friends; the exposure of infants is not justified on the plea of adding to human suffering.
Again, the differences of cookery among nations are much wider than the differences of moral sentiment; and yet no one denies a fundamental susceptibility to sweet and bitter. It is not contended that we come into the world with a knowledge of actions, but that we have certain susceptibilities of emotion, in consequence of which, it is impossible for us, in after life, unless from counteracting circumstances, to be pleased with the contemplation of certain actions, and disgusted with certain other actions. When the doctrine is thus stated, Paley's objection, that we should also receive from nature the notions of the actions themselves, falls to the ground. As well might we require an instinctive notion of all possible numbers, to bear out our instinctive sense of proportion.
A third limitation must be added, the influence of the principle of Association. One way that this operates is to transfer, to a whole class of actions, the feelings peculiar to certain marked individuals. Thus, in a civilized country, where property is largely possessed, and under complicated tenures, we become very sensitive to its violation, and acquire a proportionably intense sentiment of Justice. Again, association operates in modifying our approval and disapproval of actions according to their attendant circumstances; as when we extenuate misconduct in a beloved person.
The author contends that, notwithstanding these limitations, we still leave unimpaired the approbation of unmixed good as good, and the disapprobation of unmixed evil as evil. His further remarks, however, are mainly eloquent declamation on the universality of moral distinctions.
He proceeds to criticise the moral systems from Hobbes downwards. His remarks (Lecture 76) on the province of Reason in Morality, with reference to the systems of Clarke and Wollaston, contain the gist of the matter well expressed.
He next considers the theory of Utility. That Utility bears a certain relation to Virtue is unquestionable. Benevolence means good to others, and virtue is of course made up, in great part, of this. But then, if Utility is held to be the measure of virtue, standing in exact proportion to it, the proposition is very far from true; it is only a small portion of virtuous actions wherein the measure holds.
