Over against this reasonable and disciplined view of man and of his world stands naturalism. It exploits the defects of the classic "virtue"; it is, so to speak, humanism run to seed. Just as religion so often sinks into bigotry, cruelty and superstitition, so humanism, in lesser souls, declines to egotism, license and sentimentality. Naturalism, either by a shallow and insincere use of the materialistic view of the universe, or by the exalting of wanton feeling and whimsical fancy as ends in themselves, attempts the identification of man with the natural order, permits him to conceive of each desire, instinct, impulse, as, being natural, thereby defensible and valuable. Hence it permits him to disregard the imposed laws of civilization--those fixed points of a humane order--and to return in principle, and so far as he dares in action, to the unlimited and irresponsible individualism of the horde. Inevitably the law of the jungle is deliberately exalted, or unconsciously adopted, over against the humanist law of moderation and discipline. The humanist, then, critically studies nature and mankind, finding in her matrix and in his own spirit data for the guidance of the race, improving upon it by a cultivated and collective experience. The naturalist uncritically exalts nature, seeks identification with it so that he may freely exploit both himself and it. The faith of the one is in the self-sufficiency of the disciplined spirit of mankind; the unfaith of the other is in its glorification of the natural world and in its allegiance to the momentary devices and desires of the separate heart. It will be borne in mind that these definitions are too clear-cut; that these divisions appear in the complexities of human experience, blurred and modified by the welter of cross currents, subsidiary conflicting movements, which obscure all human problems. They represent genuine and significant divisions of thought and conduct. But they appear in actual experience as controlling emphases rather than mutually exclusive territories.
