But notwithstanding all the pains which this ingenious philosopher has taken to prove that the principle of approbation is founded in a peculiar power of perception, somewhat analogous to the external senses, there are some consequences, which he acknowledges to follow from this doctrine, that will, perhaps, be regarded by many as a sufficient confutation of it. The qualities, he allows,[26] which belong to the objects of any sense, cannot, without the greatest absurdity, be ascribed to the sense itself. Who ever thought of calling the sense of seeing black or white, the sense of hearing loud or low, or the sense of tasting sweet or bitter? And, according to him, it is equally absurd to call our moral faculties virtuous or vicious, morally good or evil. These qualities belong to the objects of those faculties, not to the faculties themselves. If any man, therefore, was so absurdly constituted as to approve of cruelty and injustice as the highest virtues, and to disapprove of equity and humanity as the most pitiful vices, such a constitution of mind might indeed be regarded as inconvenient both to the individual and to the society, and likewise as strange, surprising, and unnatural in itself; but it could not, without the greatest absurdity, be denominated vicious or morally evil. Footnote 26: Illustrations upon the Moral Sense. Sect. 1. p. 237, et seq. Third Edition. Yet surely if we saw any man shouting with admiration and applause at a barbarous and unmerited execution, which some insolent tyrant had ordered, we should not think we were guilty of any great absurdity in denominating this behaviour vicious and morally evil in the highest degree, though it expressed nothing but depraved moral faculties, or an absurd approbation of this horrid action, as of what was noble, magnanimous, and great. Our heart, I imagine, at the sight of such a spectator, would forget for a while its sympathy with the sufferer, and feel nothing but horror and detestation, at the thought of so execrable a wretch. We should abominate him even more than the tyrant who might be goaded on by the strong passions of jealousy, fear, and resentment, and upon that account be more excusable. But the sentiments of the spectator would appear altogether without cause or motive, and therefore most perfectly and completely detestable. There is no perversion of sentiment or affection which our heart would be more averse to enter into, or which it would reject with greater hatred and indignation than one of this kind; and so far from regarding such a constitution of mind as being merely something strange or inconvenient, and not in any respect vicious or morally evil, we should rather consider it as the very last and most dreadful stage of moral depravity.
