The explanation of the fallacy is however too easy to be convincing. There must have been some material, empirical reason why intelligent men were so easily entrapped by a fairly obvious fallacy. That material error was a belief in the fixity and simplicity of the self, a belief which had been fostered by a school far removed from the one in question, the theologians with their dogma of the unity and ready-made completeness of the soul. We arrive at true conceptions of motivation and interest only by the recognition that selfhood (except as it has encased itself in a shell of routine) is in process of making, and that any self is capable of including within itself a number of inconsistent selves, of unharmonized dispositions. Even a Nero may be capable upon occasion of acts of kindness. It is even conceivable that under certain circumstances he may be appalled by the consequences of cruelty, and turn to the fostering of kindlier impulses. A sympathetic person is not immune to harsh arrogances, and he may find himself involved in so much trouble as a consequence of a kindly act, that he allows his generous impulses to shrivel and henceforth governs his conduct by the dictates of the strictest worldly prudence. Inconsistencies and shiftings in character are the commonest things in experience. Only the hold of a traditional conception of the singleness and simplicity of soul and self blinds us to perceiving what they mean: the relative fluidity and diversity of the constituents of selfhood. There is no one ready-made self behind activities. There are complex, unstable, opposing attitudes, habits, impulses which gradually come to terms with one another, and assume a certain consistency of configuration, even though only by means of a distribution of inconsistencies which keeps them in water-tight compartments, giving them separate turns or tricks in action.
