(2) There is a strange delight in wide generalization merely as such, which, when pursued without reference to the ends which it subserves, and without regard to its actual functioning, often results in a sort of logical vertigo. This probably has much to do with the peculiar "craving for unity" which is held to be the distinctive affliction of philosophers. At any rate, the thought of an all-embracing One or Whole seems to be regarded as valuable and elevating quite apart from any definite function it performs in knowing, or light it throws on any actual problem. (3) The thought of an Absolute Unity is cherished as a guarantee of cosmic stability. In face of the restless vicissitudes of phenomena it seems to secure us against falling out of the Universe. It assures us _a_ _priori_--and that is its supreme value--that the cosmic order cannot fall to pieces and leave us dazed and confounded among the debris.... We want to have an absolute assurance _a priori_ concerning the future, and the thought of the absolute seems designed to give it. It is probably this last notion that, consciously or unconsciously, weighs most in the psychology of the Absolutists' creed. In this connection the reader will recall the passage quoted from Adler's _The Neurotic Constitution_, in which it was shown that the fictitious "guiding-lines" or rational systems of both the neurotic and normal are motivated by this craving for security. But it makes all the difference in the world whether the system of ideas is used, as in science and common sense, to solve real problems in an objective world, or is created to be an artificial and imaginary defense of the ego against a subjective feeling of insecurity; whether, in a word, the craving for security moves one to do something calculated to render the forces with which he must deal concretely more congenial and hospitable to his will, or makes him content to withdraw and file a demur to the challenge of the environment in the form of theoretical denial of the reality of the situation. There is no denying the fact that Absolute Idealism, if not taken too seriously, may have the function for some people of steadying their nerves in the battle of life. And though, as I believe, logically untenable, it not infrequently serves as a rationalization of faith-values which work out beneficially, and, quite apart from their metaphysical trappings, may be even indispensable. Yet when carried to its logical conclusions such thinking inevitably distorts the meaning of personal living, robs our world and our acts of their feeling of reality, serves as an instrument for "regression" or withdrawal of interest from the real tasks and objects of living men and women, and in fact functions for much the same purpose, if not precisely in the same way, as do the ideal systems of the psychopath.
