“Our self-abnegation is thus not for our own sake but for the sake of others. And thus it is not to mere self-denial that Christ calls us but specifically to self-sacrifice, not to unselfing ourselves but to unselfishing ourselves. Self-denial for its own sake is in its very nature ascetic, monkish. It concentrates our whole attention on self—self-knowledge, self-control—and can therefore eventuate in nothing other than the very apotheosis of selfishness. At best it succeeds only in subjecting the outer self to the inner self or the lower self to the higher self, and only the more surely falls into the slough of self-seeking, that it partially conceals the selfishness of its goal by refining its ideal of self and excluding its grosser and more outward elements. Self-denial, then, drives to the cloister, narrows and contracts the soul, murders within us all innocent desires, dries up all the springs of sympathy, and nurses and coddles our self-importance until we grow so great in our own esteem as to be careless of the trials and sufferings, the joys and aspirations, the strivings and failures and successes of our fellow-men. Self-denial, thus understood, will make us cold, hard, unsympathetic—proud, arrogant, self-esteeming—fanatical, overbearing, cruel. It may make monks and Stoics, it cannot make Christians.”
