OWING to the defects of our mentality uniformity has to a certain extent to be admitted and sought after; still the real aim of Nature is a true unity supporting a rich diversity. Her secret is clear enough from the fact that though she moulds on one general plan, she insists always on an infinite variation. The plan of the human form is one, yet no two human beings are precisely alike in their physical characteristics. Human nature is one in its constituents and its grand lines, but no two human beings are precisely alike in their temperament, characteristics and psychological substance. All life is one in its essential plan and principle; even the plant is a recognisable brother of the animal, but the unity of life admits and encourages an infinite variety of types. The natural variation of human communities from each other proceeds on the same plan as the variation of individuals; each develops its own character, variant principle, natural law. This variation and fundamental following of its own separate law is necessary to its life, but it is equally necessary to the healthy total life of mankind. For the principle of variation does not prevent free interchange, does not oppose the enrichment of all from a common stock and of the common stock by all which we have seen to be the ideal principle of existence; on the contrary, without a secure variation such interchange and mutual assimilation would be out of the question. Therefore we see that in this harmony between our unity and our diversity lies the secret of life; Nature insists equally in all her works upon unity and upon variation. We shall find that a real spiritual and psychological unity can allow a free diversity and dispense with all but the minimum of uniformity which is sufficient to embody the community of nature and of essential principle. Until we can arrive at that perfection, the method of uniformity has to be applied, but we must not overapply it on peril of discouraging life in the very sources of its power, richness and sane natural self-unfolding.
