As a person may act wrong by following a wrong sense of duty, so nature may sometimes prevail, and lead him to act right in opposition to it. We cannot in this case be displeased to see that motive prevail, which we think ought to prevail, though the person himself is so weak as to think otherwise. As his conduct, however, is the effect of weakness, not principle, we are far from bestowing upon it any thing that approaches to complete approbation. A bigotted Roman Catholic, who, during the massacre of St. Bartholomew, had been so overcome by compassion, as to save some unhappy protestants, whom he thought it his duty to destroy, would not seem to be entitled to that high applause which we should have bestowed upon him, had he exerted the same generosity with complete self-approbation. We might be pleased with the humanity of his temper, but we should still regard him with a sort of pity which is altogether inconsistent with the admiration that is due to perfect virtue. It is the same case with all the other passions. We do not dislike to see them exert themselves properly, even when a false notion of duty would direct the person to restrain them. A very devout Quaker, who upon being struck upon one cheek, instead of turning up the other, should so far forget his literal interpretation of our Saviour’s precept, as to bestow some good discipline upon the brute that insulted him, would not be disagreeable to us. We should laugh and be diverted with his spirit, and rather like him the better for it. But we should by no means regard him with that respect and esteem which would seem due to one who, upon a like occasion, had acted properly from a just sense of what was proper to be done. No action can properly be called virtuous, which is not accompanied with the sentiment of self-approbation. [Illustration] PART IV. Of the EFFECT of UTILITY upon the sentiment of approbation. CONSISTING OF ONE SECTION. CHAP. I. _Of the beauty which the appearance of_ UTILITY _bestows upon all the productions of art, and of the extensive influence of this species of beauty_. That utility is one of the principal sources of beauty has been observed by every body, who has considered with any attention what constitutes the nature of beauty. The conveniency of a house gives pleasure to the spectator as well as its regularity, and he is as much hurt when he observes the contrary defect, as when he sees the correspondent windows of different forms, or the door not placed exactly in the middle of the building. That the fitness of any system or machine to produce the end for which it was intended, bestows a certain propriety and beauty upon the whole, and renders the very thought and contemplation of it agreeable, is so very obvious that nobody has overlooked it.
