As for the Christian dogmas, it is known that they were elaborated in a series of theological and literary works and in the Councils, principally by the converted neo-Platonists of the Orient. The Greek mind had fallen so low that, in the fourth century of the Christian era, the period of the first Council, the idea of a personal God, pure, eternal, absolute mind, creator and supreme master, existing outside of the world, was unanimously accepted by the Church Fathers; as a logical consequence of this absolute absurdity, it then became natural and necessary to believe in the immateriality and immortality of the human soul, lodged and imprisoned in a body only partially mortal, there being in this body itself a portion which, while material, is immortal like the soul, and must be resurrected with it. We see how difficult it was, even for the Church Fathers, to conceive pure minds outside of any material form. It should be added that, in general, it is the character of every metaphysical and theological argument to seek to explain one absurdity by another. It was very fortunate for Christianity that it met a world of slaves. It had another piece of good luck in the invasion of the Barbarians. The latter were worthy people, full of natural force, and, above all, urged on by a great necessity of life and a great capacity for it; brigands who had stood every test, capable of devastating and gobbling up anything, like their successors, the Germans of to-day; but they were much less systematic and pedantic than these last, much less moralistic, less learned, and on the other hand much more independent and proud, capable of science and not incapable of liberty, as are the bourgeois of modern Germany. But, in spite of all their great qualities, they were nothing but barbarians--that is, as indifferent to all questions of theology and metaphysics as the ancient slaves, a great number of whom, moreover, belonged to their race. So that, their practical repugnance once overcome, it was not difficult to convert them theoretically to Christianity. For ten centuries Christianity, armed with the omnipotence of Church and State and opposed by no competition, was able to deprave, debase, and falsify the mind of Europe. It had no competitors, because outside of the Church there were neither thinkers nor educated persons. It alone thought, it alone spoke and wrote, it alone taught. Though heresies arose in its bosom, they affected only the theological or practical developments of the fundamental dogma, never that dogma itself. The belief in God, pure spirit and creator of the world, and the belief in the immateriality of the soul remained untouched. This double belief became the ideal basis of the whole Occidental and Oriental civilization of Europe; it penetrated and became incarnate in all the institutions, all the details of the public and private life of all classes, and the masses as well.
