There is a degree, however, in which we suppose that the care of ourselves becomes a source of painful anxiety and cruel passions; in which it degenerates into avarice, vanity, or pride; and in which, by fostering habits of jealousy and envy, of fear and malice, it becomes as destructive of our own enjoyments, as it is hostile to the welfare of mankind. This evil, however, is not to be charged upon any excess in the care of ourselves, but upon a mere mistake in the choice of our objects. We look abroad for a happiness which is to be found only in the qualities of the heart: we think ourselves dependent on accidents; and are therefore kept in suspense and solicitude. We think ourselves dependent on the will of other men; and are therefore servile and timid: we think our felicity is placed in subjects for which our fellow creatures are rivals and competitors; and in pursuit of happiness, we engage in those scenes of emulation, envy, hatred, animosity, and revenge, that lead to the highest pitch of distress. We act, in short, as if to preserve ourselves were to retain our weakness, and perpetuate our sufferings. We charge the ills of a distempered imagination, and a corrupt heart, to the account of our fellow creatures, to whom we refer the pangs of our disappointment or malice; and while we foster our misery, are surprised that the care of ourselves is attended with no better effects. But he who remembers that he is by nature a rational being, and a member of society; that to preserve himself, is to preserve his reason, and to preserve the best feelings of his heart; will encounter with none of these inconveniencies; and in the care of himself, will find subjects only of satisfaction and triumph. The division of our appetites into benevolent and selfish, has probably, in some degree, helped to mislead our apprehension on the subject of personal enjoyment and private good; and our zeal to prove that virtue is disinterested, has not greatly promoted its cause. The gratification of a selfish desire, it is thought, brings advantage or pleasure to ourselves; that of benevolence terminates in the pleasure or advantage of others: whereas, in reality, the gratification of every desire is a personal enjoyment, and its value being proportioned to the particular quality or force of the sentiment, it may happen that the same person may reap a greater advantage from the good fortune he has procured to another, than from that he has obtained for himself.
