Still, movement and differentiation must be included within a vital whole; and the relation to activity which is the chief factor in life cannot be given up even at its greatest depth. The high estimate of spirituality may not rightly lead to a mean estimate of nature, to a conflict with nature such as has been the case in the realm of religion in the tendency to asceticism. For as certainly as our acknowledgment of an independent spirituality involves a subordination of nature, this subordination does not imply a mean estimate, still less a rejection. Asceticism which appears to be the attainment of a high level of spiritual life soon leads to an inward degeneration. For in asceticism the chief task is not the powerful development and courageous advance of spirituality, but simply a negation and suppression of sense. Reflection and thought will thus be centred upon just those things beyond which the spiritual movement wishes to lead. Particular temporary circumstances may make the tendency to asceticism comprehensible; such times were over-refined and diseased, and the diseased may not rightly give to life its rule. But if, in this way, we oppose a specifically religious or ascetic form of life we are not prevented from acknowledging the strong and fruitful influence of a world of transcendent inwardness upon life as a whole. For its perfect health and breadth, our life needs two tendencies which, though they directly contradict each other, must, nevertheless, within us be complementary to each other: it needs an energetic conflict against all that is irrational, and at the same time to be elevated into a sphere in which everything is rational, into a realm of peace and perfection. Within the spiritual life itself, tasks are given their form and are estimated on the one hand from the human point of view, and on the other from an ultimate, one might say an absolute, view of things. The significance of this distinction is to be seen most clearly in history, and, perhaps, in the contrast between the Greek and the Christian character. The former places man in the midst of the world, and requires him energetically to take up the struggle for the cause of rationality and decisively to reject the irrational. Suffering and pain were to be avoided; man was never to submit to them. Courage appeared to be the chief quality of this form of life, and in relation to others justice was its determining idea. But if this idea demands that each should receive according to his achievement, then the higher and the lower, the noble and the common, must be distinctly separated and never allowed to be confused. That the noble form a small minority, and that history hardly promises any change in this matter, is a fact that has not escaped perception; and the permanence of the antithesis of an esoteric and an exoteric form, therefore, appears to be inevitable. The difference that exists is regarded as due primarily to nature, not to free decision.
