All human knowledge is more or less clear. By what strange fatality have we never been able to elucidate the science of God? The most civilized nations, and among them the most profound thinkers, are in this respect no more enlightened than the most savage tribes and ignorant peasants; and, examining the subject closely, we shall find, that, by the speculations and subtle refinements of men, the divine science has been only more and more obscured. Every religion has hitherto been founded only upon what is called, in logic, begging the question; it takes things for granted, and then proves, by suppositions, instead of principles.
