To meet this need humanity has the special power of producing men who give a new meaning to the whole of human life--a theory of life from which follow new forms of activity quite different from all preceding them. The formation of this philosophy of life appropriate to humanity in the new conditions on which it is entering, and of the practice resulting from it, is what is called religion.
And therefore, in the first place, religion is not, as science imagines, a manifestation which at one time corresponded with the development of humanity, but is afterward outgrown by it. It is a manifestation always inherent in the life of humanity, and is as indispensable, as inherent in humanity at the present time as at any other. Secondly, religion is always the theory of the practice of the future and not of the past, and therefore it is clear that investigation of past manifestations cannot in any case grasp the essence of religion.
The essence of every religious teaching lies not in the desire for a symbolic expression of the forces of nature, nor in the dread of these forces, nor in the craving for the marvelous, nor in the external forms in which it is manifested, as men of science imagine; the essence of religion lies in the faculty of men of foreseeing and pointing out the path of life along which humanity must move in the discovery of a new theory of life, as a result of which the whole future conduct of humanity is changed and different from all that has been before.
