Darwinism and Marxism constitute one gospel, the only true, comprehensive and sufficient gospel which the world has ever had or can have, and there is no hope for the future of mankind except in it. If it fails the world is lost, but it shall not and indeed cannot fail, for its words are so many acts or facts of nature.
There is no fact which is not such an act, and every such fact is a part of the one only law upon the knowing and doing of which terrestrial life and its happiness are wholly and solely dependent.
Yes, life, long life, happy life, all there is of such human life, or divine life, (if there be any), depends entirely upon a knowledge of and conformity to this law which is the doing of nature, and not at all upon any law which is the willing of a god, if indeed there is such a law.
Neither the religion nor the politics which enters into the constitution of Marxian or proletarian socialism is at all concerned about the heaven above or the hell below the earth, if there are such places: but the concern of both is wholly to ring out a hell from the earth and to ring in a heaven upon it.
Nor have the religion and politics which constitute this socialism the least concern about the service of a celestial divinity (Jesus, Jehovah, Allah, Buddha or any other) by doing his will; but both are much concerned with the service of humanity, which consists in rightly learning, interpreting and using the laws of nature, wholly for the purpose of making the terrestrial lives of men, women and children as long and happy as possible, and with absolutely no reference to any celestial life which may be either above or below the earth.
Religion and politics are the complementary and inseparable halves of the social sphere, religion being its idealism and politics its practicalism.
Religious idealism is a social soul of which the church should be the embodiment.
Political practicalism is a social soul of which the state should be the embodiment.
Contrary to the representations of orthodox Christianism it is impossible for any soul to exist without an embodiment.
In truth the body produces the soul, not the soul the body. We must have the church and state in order that we may have their souls, idealism and practicalism.
