"Turning next to the second effect of prolonged habituation, we find that, with objects or actions with which pleasure was at first associated and which so were called pleasurable, further association often connects a subsequent pain which increased experience has shown always to follow upon the immediate pleasure. This pain often more than counterbalances the preceding pleasure; hence when it is taken into the emotion, that emotion becomes one no longer of appetition but of aversion, and the object or action is remembered as one not to be sought after but avoided. It cannot, however, be called painful, because it causes immediate pleasure, so a new name has to be invented, and it is called Bad, or Evil. Similarly, many things which are immediately associated with pain are found to be eventually followed by pleasure which more than counterbalances the pain, and as this experience becomes consolidated by the power of association, they attract rather than repel, and for a name whereby to distinguish them, are called Good; so that Good and Evil are correlative terms like Pleasure and Pain, and mean respectively the greatest total Pleasure, and the greatest total Pain. Now this experience when once acquired is never lost, but by virtue of hereditary transmission descends from parents to children. But, as in the case of the simpler emotions, only the results survive, and not the means whereby they were arrived at; so that, in a short time, the words Good and Evil come to be quite separated from Pleasant and Painful; nay, as might be expected from their origin, they tend to acquire exactly opposite meanings; for Pleasure and Pain come to signify only immediate pleasure and pain; and the final reckoning is often considerably at variance with the first item; as in a race the man who leads for the first lap seldom wins in the end.... "This, then, is the origin of the Moral Sense.... The Moral Sense, therefore, is merely one of the emotions," though the last of all in the order of evolution; it can only claim a life of some two or three centuries; and there are even some who still doubt its existence. "Man at any rate is the only animal who possesses it in its latest development; for even in horses and dogs we cannot believe that it has passed the intentional or conscious stage.... Good, with them, has no artificial meaning; it is simply identical with the greatest pleasure." Only by complete and perfect obedience to all emotions can perfect freedom from regret be obtained in the gratification of all desire. Man is at present passion's slave, because he is so only in part; "for the cause of repentance is never the attainment of some pleasure, but always the non-attainment of more: not the satisfaction of one desire, but the inability to satisfy all. The highest virtue, therefore, consists in being led, not by one desire, but by all; in the complete organization of the Moral Nature." OF THE SOCIAL RELATION OF THE INDIVIDUAL
