First, let it be remarked that not one of the illustrious men I have just named nor any other idealistic thinker of any consequence in our day has given any attention to the logical side of this question properly speaking. Not one has tried to settle philosophically the possibility of the divine _salto mortale_ from the pure and eternal regions of spirit into the mire of the material world. Have they feared to approach this irreconcilable contradiction and despaired of solving it after the failures of the greatest geniuses of history, or have they looked upon it as already sufficiently well settled? That is their secret. The fact is that they have neglected the theoretical demonstration of the existence of a God, and have developed only its practical motives and consequences. They have treated it as a fact universally accepted, and, as such, no longer susceptible of any doubt whatever, for sole proof thereof limiting themselves to the establishment of the antiquity and this very universality of the belief in God. This imposing unanimity, in the eyes of many illustrious men and writers to quote only the most famous of them who eloquently expressed it, Joseph de Maistre and the great Italian patriot, Giuseppe Mazzini--is of more value than all the demonstrations of science; and if the reasoning of a small number of logical and even very powerful, but isolated, thinkers is against it, so much the worse, they say, for these thinkers and their logic, for universal consent, the general and primitive adoption of an idea, has always been considered the most triumphant testimony to its truth. The sentiment of the whole world, a conviction that is found and maintained always and everywhere, cannot be mistaken; it must have its root in a necessity absolutely inherent in the very nature of man. And since it has been established that all peoples, past and present, have believed and still believe in the existence of God, it is clear that those who have the misfortune to doubt it, whatever the logic that led them to this doubt, are abnormal exceptions, monsters. Thus, then, the _antiquity_ and _universality_ of a belief should be regarded, contrary to all science and all logic, as sufficient and unimpeachable proof of its truth. Why? Until the days of Copernicus and Galileo everybody believed that the sun revolved about the earth. Was not everybody mistaken? What is more ancient and more universal than slavery? Cannibalism perhaps. From the origin of historic society down to the present day there has been always and everywhere exploitation of the compulsory labor of the masses--slaves, serfs, or wage-workers--by some dominant minority; oppression of the people by the Church and by the State. Must it be concluded that this exploitation and this oppression are necessities absolutely inherent in the very existence of human society? These are examples which show that the argument of the champions of God proves nothing.
