[9] The idealists, all those who believe in the immateriality and immortality of the human soul, must be excessively embarrassed by the difference in intelligence existing between races, peoples, and individuals. Unless we suppose that the various divine particles have been irregularly distributed, how is this difference to be explained? Unfortunately there is a considerable number of men wholly stupid, foolish even to idiocy. Could they have received in the distribution a particle at once divine and stupid? To escape this embarrassment the idealists must necessarily suppose that all human souls are equal, but that the prisons in which they find themselves necessarily confined, human bodies, are unequal, some more capable than others of serving as an organ for the pure intellectuality of soul. According to this, such a one might have very fine organs at his disposition, such another very gross organs. But these are distinctions which idealism has not the power to use without falling into inconsistency and the grossest materialism; for in the presence of absolute immateriality of soul all bodily differences disappear, all that is corporeal, material, necessarily appearing indifferent, equally and absolutely gross. The abyss which separates soul from body, absolute immateriality from absolute materiality, is infinite. Consequently all differences, by the way inexplicable and logically impossible, which may exist on the other side of the abyss, in matter, should be to the soul null and void, and neither can nor should exercise any influence over it. In a word, the absolutely immaterial cannot be constrained, imprisoned, and much less expressed in any degree whatsoever by the absolutely material. Of all the gross and materialistic (using the word in the sense attached to it by the idealists) imaginations which were engendered by the primitive ignorance and stupidity of men, that of an immaterial soul imprisoned in a material body is certainly the grossest, the most stupid, and nothing better proves the omnipotence exercised by ancient prejudices even over the best minds than the deplorable sight of men endowed with lofty intelligence still talking of it in our days. [10] I am well aware that in the theological and metaphysical systems of the Orient, and especially in those of India, including Buddhism, we find the principle of the annihilation of the real world in favor of the ideal and of absolute abstraction. But it has not the added character of voluntary and deliberate negation which distinguishes Christianity; when those systems were conceived, the world of human thought, of will and of liberty, had not reached that stage of development which was afterwards seen in the Greek and Roman civilization.
