Virtue, my pet, is an abstract idea, varying in its manifestations with the surroundings. Virtue in Provence, in Constantinople, in London, and in Paris bears very different fruit, but is none the less virtue.
A sick man, surrounded by those who love him, nursed by those who wish earnestly that he should live, will recover (all other things being equal), when another patient tended by hirelings will die. Doctors decline to see unconscious magnestism in this phenomenon; for them it is the result of intelligent nursing, of exact obedience to their orders; but many a mother knows the virtue of such ardent projections of strong, unceasing prayer.
Self-love is as protective as the Deity; Disenchantment is as perspicacious as a surgeon; Experience is as provident as a mother. Such are the theologic virtues of marriage.
