"Vanity, or to call it by a gentler name, the desire of admiration and applause, is, perhaps, the most universal principle of humanactions.... Where that desire is wanting, we are apt to be indifferent, listless, indolent, and inert.... I will own to you, under the secrecy of confession, that my vanity has very often made me take great pains to make many a woman in love with me, if I could, for whose person I would not have given a pinch of snuff."
