A particularly severe conflict with regard to the problem of the unity of life arises between the natural condition of man and the requirements of an independent spiritual life. The spiritual life demands an enduring whole which includes all multiplicity within itself and of which the movement originates within: human existence is primarily a juxtaposition of individuals and a succession of moments; no union seems to be more than that which is constituted by a mere collection of the individuals. If the division were not in some way transcended no spiritual life could grow up within humanity, and man have no share in the building up of a spiritual world. The nineteenth century gave a confident answer to the problem: it contended that history and society of their own capacity bind the elements of life into stable forms which take up all multiplicity into themselves and raise our existence to spirituality. We most emphatically deny the validity of this contention, and hope to show that history and society themselves involve difficult problems; further, that only when we conceive them in a particular way are they able to help in the unification of life and then only in a limited manner; and lastly, that they do not so much produce a spiritual life as presuppose it, as essential to their own existence. Naturalism and Intellectualism have also confused the outlook; if we free it from this confusion, history and society will take a secondary place in our estimation; they will themselves be seen to be deeper and more comprehensive and to involve movements which extend further than appears in immediate experience; and they will become witnesses to the living presence of the spiritual life within humanity.
