After all, it must be confessed, that if a principle of affection to mankind be the basis of our moral approbation and dislike, we sometimes proceed in distributing applause or censure, without precisely attending to the degree in which our fellow creatures are hurt or obliged; and that, besides the virtues of candour, friendship, generosity, and public spirit, which bear an immediate reference to this principle, there are others which may seem to derive their commendation from a different source. Temperance, prudence, fortitude, are those qualities likewise admired from a principle of regard to our fellow creatures? Why not, since they render men happy in themselves, and useful to others? He who is qualified to promote the welfare of mankind, is neither a sot, a fool, nor a coward. Can it be more clearly expressed, that temperance, prudence, and fortitude, are necessary to the character we love and admire? I know well why I should wish for them in myself; and why likewise I should wish for them in my friend, and in every person who is an object of my affection. But to what purpose seek for reasons of approbation, where qualities are so necessary to our happiness, and so great a part in the perfection of our nature? We must cease to esteem ourselves, and to distinguish what is excellent, when such qualifications incur our neglect. A person of an affectionate mind, possessed of a maxim, that he himself, as an individual, is no more than a part of the whole that demands his regard, has found, in that principle, a sufficient foundation for all the virtues; for a contempt of animal pleasures, that would supplant his principal enjoyment; for an equal contempt of danger or pain, that come to stop his pursuits of public good. "A vehement and steady affection magnifies its object, and lessens every difficulty or danger that stands in the way." "Ask those who have been in love," says Epictetus, "they will know that I speak the truth." "I have before me," says another eminent moralist, [Footnote: Persian Letters.] "an idea of justice, which if I could follow in every instance, I should think myself the most happy of men." And it is of consequence to their happiness, as well as to their conduct, if those can be disjoined, that men should have this idea properly formed. It is perhaps but another name for that good of mankind, which the virtuous are engaged to promote. If virtue be the supreme good, its best and most signal effect is, to communicate and diffuse itself.
