Regard to our own private happiness and interest too, appear upon many occasions very laudable principles of action. The habits of œconomy, industry, discretion, attention, and application of thought, are generally supposed to be cultivated from self-interested motives, and at the same time are apprehended to be very praise-worthy qualities, which deserve the esteem and approbation of every body. The mixture of a selfish motive, it is true, seems often to sully the beauty of those actions which ought to arise from a benevolent affection. The cause of this, however, is not that self-love can never be the motive of a virtuous action, but that the benevolent principle appears in this particular case to want its due degree of strength, and to be altogether unsuitable to its object. The character, therefore, seems evidently imperfect, and upon the whole to deserve blame rather than praise. The mixture of a benevolent motive in an action to which self-love alone ought to be sufficient to prompt us, is not so apt indeed to diminish our sense of its propriety, or of the virtue of the person who performs it. We are not ready to suspect any person of being defective in selfishness. This is by no means the weak side of human nature, or the failing of which we are apt to be suspicious. If we could really believe, however, of any man, that, was it not from a regard to his family and friends, he would not take that proper care of his health, his life, or his fortune, to which self-preservation alone ought to be sufficient to prompt him, it would undoubtedly be a failing, tho’ one of those amiable failings, which render a person rather the object of pity than of contempt or hatred. It would still, however, somewhat diminish the dignity and respectableness of his character. Carelessness and want of œconomy are universally disapproved of, not, however as proceeding from a want of benevolence, but from a want of the proper attention to the objects of self-interest. Though the standard by which casuists frequently determine what is right or wrong in human conduct, be its tendency to the welfare or disorder of society, it does not follow that a regard to the welfare of society should be the sole virtuous motive of action, but only that, in any competition, it ought to cast the balance against all other motives.
