But the idea of deity coincides with the idea of humanity. All divine attributes, all the attributes which make God God, are attributes of the species--attributes which in the individual are limited, but the limits of which are abolished in the essence of the species, and even in its existence, in so far as it has its complete existence only in all men taken together. My knowledge, my will, is limited; but my limit is not the limit of another man, to say nothing of mankind; what is difficult to me is easy to another; what is impossible, inconceivable, to one age, is to the coming age conceivable and possible. My life is bound to a limited time; not so the life of humanity. The history of mankind consists of nothing else than a continuous and progressive conquest of limits, which at a given time pass for the limits of humanity, and therefore for absolute insurmountable limits. But the future always unveils the fact that the alleged limits of the species were only limits of individuals. The most striking proofs of this are presented by the history of philosophy and of physical science. It would be highly interesting and instructive to write a history of the sciences entirely from this point of view, in order to exhibit in all its vanity the presumptuous notion of the individual that he can set limits to his race. Thus the species is unlimited; the individual alone limited. But the sense of limitation is painful, and hence the individual frees himself from it by the contemplation of the perfect Being; in this contemplation he possesses what otherwise is wanting to him. With the Christians God is nothing else than the immediate unity of species and individuality, of the universal and individual being. God is the idea of the species as an individual--the idea or essence of the species, which as a species, as universal being, as the totality of all perfections, of all attributes or realities, freed from all the limits which exist in the consciousness and feeling of the individual, is at the same time again an individual, personal being. Ipse suum esse est. Essence and existence are in God identical; which means nothing else than that he is the idea, the essence of the species, conceived immediately as an existence, an individual. The highest idea on the standpoint of religion is: God does not love, he is himself love; he does not live, he is life; he is not just, but justice itself; not a person, but personality itself,--the species, the idea, as immediately a concrete existence.
