=Origin of the Doctrine.=--The notion arises from the tendency to identify the self with one of its own factors. It is one and the same self which conceives and is interested in some generous and ideal good that is also tempted by some near, narrow, and exclusive good. The force of the latter resides in the _habitual_ self, in purposes which have got themselves inwrought into the texture of ordinary character. Hence there is a disposition to overlook the complexity of selfhood, and to identify it with those factors in the self which resist ideal aspiration, and which are recalcitrant to the thought of duty; to identify the self with impulses that are inclined to what is frivolous, sensuous and sensual, pleasure-seeking. All vice being, then, egoism, selfishness, self-seeking, the remedy is to check it at its roots; to keep the self down in its proper place, denying it, chastening it, mortifying it, refusing to listen to its promptings. Ignoring the variety and subtlety of the factors that make up the self, all the different elements of right and of wrong are gathered together and set over against each other. All the good is placed once for all in some outside source, some higher law or ideal; and the source of all evil is placed within the corrupted and vile self. When one has become conscious of the serious nature of the moral struggle; has found that vice is easy, and to err "natural," needing only to give way to some habitual impulse or desire; that virtue is arduous, requiring resistance and strenuous effort, one is apt to overlook the habitual tendencies which are the ministers of the higher goods. One forgets that unless ideal ends were also rooted in some natural tendencies of the self, they could neither occur to the self nor appeal to the self. Hence everything is swept into the idea that the self is inherently so evil that it must be denied, snubbed, sacrificed, mortified. In general, to point out the truth which this theory perverts, to emphasize the demand for constant reconstruction and rearrangement of the habitual powers of the self--is sufficient criticism of it. But in detail the theory exercises such pervasive influence that it is worth while to mention specifically some of the evils that accrue from it.
