The first condition was fulfilled by the Romans, though in a very negative way no doubt, by the conquest of most of the countries known to the ancients and by the destruction of their national institutions. The gods of all the conquered nations, gathered in the Pantheon, mutually cancelled each other. This was the first draft of humanity, very gross and quite negative.
As for the second condition, the spiritualization of Jehovah, that was realized by the Greeks long before the conquest of their country by the Romans. They were the creators of metaphysics. Greece, in the cradle of her history, had already found from the Orient a divine world which had been definitely established in the traditional faith of her peoples; this world had been left and handed over to her by the Orient. In her instinctive period, prior to her political history, she had developed and prodigiously humanized this divine world through her poets; and when she actually began her history, she already had a religion ready-made, the most sympathetic and noble of all the religions which have existed, so far at least as a religion—that is, a lie—can be noble and sympathetic. Her great thinkers—and no nation has had greater than Greece—found the divine world established, not only outside of themselves in the people, but also in themselves as a habit of feeling and thought, and naturally they took it as a point of departure. That they made no theology—that is, that they did not wait in vain to reconcile dawning reason with the absurdities of such a god, as did the scholastics of the Middle Ages—was already much in their favor. They left the gods out of their speculations and attached themselves directly to the divine idea, one, invisible, omnipotent, eternal, and absolutely spiritualistic but impersonal. As concerns Spiritualism, then, the Greek metaphysicians, much more than the Jews, were the creators of the Christian god. The Jews only added to it the brutal personality of their Jehovah.
That a sublime genius like the divine Plato could have been absolutely convinced of the reality of the divine idea shows us how contagious, how omnipotent, is the tradition of the religious mania even on the greatest minds. Besides, we should not be surprised at it, since, even in our day, the greatest philosophical genius which has existed since Aristotle and Plato, Hegel—in spite even of Kant’s criticism, imperfect and too metaphysical though it be, which had demolished the objectivity or reality of the divine ideas—tried to replace these divine ideas upon their transcendental or celestial throne. It is true that Hegel went about his work of restoration in so impolite a manner that he killed the good God for ever. He took away from these ideas their divine halo, by showing to whoever will read him that they were never anything more than a creation of the human mind running through history in search of itself. To put an end to all religious insanities and the divine mirage, he left nothing lacking but the utterance of those grand words which were said after him, almost at the same time, by two great minds who had never heard of each other—Ludwig Feuerbach, the disciple and demolisher of Hegel, in Germany, and Auguste Comte, the founder of positive philosophy, in France. These words were as follows:
“Metaphysics are reduced to psychology.” All the metaphysical systems have been nothing else than human psychology developing itself in history.
To-day it is no longer difficult to understand how the divine ideas were born, how they were created in succession by the abstractive faculty of man. Man made the gods. But in the time of Plato this knowledge was impossible. The collective mind, and consequently the individual mind as well, even that of the greatest genius, was not ripe for that. Scarcely had it said with Socrates: “Know thyself!” This self-knowledge existed only in a state of intuition; in fact, it amounted to nothing. Hence it was impossible for the human mind to suspect that it was itself the sole creator of the divine world. It found the divine world before it; it found it as history, as tradition, as a sentiment, as a habit of thought; and it necessarily made it the object of its loftiest speculations. Thus was born metaphysics, and thus were developed and perfected the divine ideas, the basis of Spiritualism.
It is true that after Plato there was a sort of inverse movement in the development of the mind. Aristotle, the true father of science and positive philosophy, did not deny the divine world, but concerned himself with it as little as possible. He was the first to study, like the analyst and experimenter that he was, logic, the laws of human thought, and at the same time the physical world, not in its ideal, illusory essence, but in its real aspect. After him the Greeks of Alexandria established the first school of the positive scientists. They were atheists. But their atheism left no mark on their contemporaries. Science tended more and more to separate itself from life. After Plato, divine ideas were rejected in metaphysics themselves; this was done by the Epicureans and Skeptics, two sects who contributed much to the degradation of human aristocracy, but they had no effect upon the masses.
Another school, infinitely more influential, was formed at Alexandria. This was the school of neo-Platonists. These, confounding in an impure mixture the monstrous imaginations of the Orient with the ideas of Plato, were the true originators, and later the elaborators, of the Christian dogmas.
Thus the personal and gross egoism of Jehovah, the not less brutal and gross Roman conquest, and the metaphysical ideal speculation of the Greeks, materialized by contact with the Orient, were the three historical elements which made up the spiritualistic religion of the Christians.
Before the altar of a unique and supreme God was raised on the ruins of the numerous altars of the pagan gods, the autonomy of the various nations composing the pagan or ancient world had to be destroyed first. This was very brutally done by the Romans who, by conquering the greatest part of the globe known to the ancients, laid the first foundations, quite gross and negative ones no doubt, of humanity. A God thus raised above the national differences, material and social, of all countries, and in a certain sense the direct negation of them, must necessarily be an immaterial and abstract being. But faith in the existence of such a being, so difficult a matter, could not spring into existence suddenly. Consequently, as I have demonstrated in the Appendix, it went through a long course of preparation and development at the hands of Greek metaphysics, which were the first to establish in a philosophical manner the notion of the divine idea, a model eternally creative and always reproduced by the visible world. But the divinity conceived and created by Greek philosophy was an impersonal divinity. No logical and serious metaphysics being able to rise, or, rather, to descend, to the idea of a personal God, it became necessary, therefore, to imagine a God who was one and very personal at once. He was found in the very brutal, selfish, and cruel person of Jehovah, the national God of the Jews. But the Jews, in spite of that exclusive national spirit which distinguishes them even to-day, had become in fact, long before the birth of Christ, the most international people of the world. Some of them carried away as captives, but many more even urged on by that mercantile passion which constitutes one of the principal traits of their character, they had spread through all countries, carrying everywhere the worship of their Jehovah, to whom they remained all the more faithful the more he abandoned them.
