I have stated the chief practical reason of the power still exercised to-day over the masses by religious beliefs. These mystical tendencies do not signify in man so much an aberration of mind as a deep discontent at heart. They are the instinctive and passionate protest of the human being against the narrowness, the platitudes, the sorrows, and the shame of a wretched existence. For this malady, I have already said, there is but one remedy--Social Revolution. In the meantime I have endeavored to show the causes responsible for the birth and historical development of religious hallucinations in the human conscience. Here it is my purpose to treat this question of the existence of a God, or of the divine origin of the world and of man, solely from the standpoint of its moral and social utility, and I shall say only a few words, to better explain my thought, regarding the theoretical grounds of this belief. All religions, with their gods, their demigods, and their prophets, their messiahs and their saints, were created by the credulous fancy of men who had not attained the full development and full possession of their faculties. Consequently, the religious heaven is nothing but a mirage in which man, exalted by ignorance and faith, discovers his own image, but enlarged and reversed--that is, _divinized_. The history of religions, of the birth, grandeur, and decline of the gods who have succeeded one another in human belief, is nothing, therefore, but the development of the collective intelligence and conscience of mankind. As fast as they discovered, in the course of their historically progressive advance, either in themselves or in external nature, a power, a quality, or even any great defect whatever, they attributed them to their gods, after having exaggerated and enlarged them beyond measure, after the manner of children, by an act of their religious fancy. Thanks to this modesty and pious generosity of believing and credulous men, heaven has grown rich with the spoils of the earth, and, by a necessary consequence, the richer heaven became, the more wretched became humanity and the earth. God once installed, he was naturally proclaimed the cause, reason, arbiter, and absolute disposer of all things: the world thenceforth was nothing, God was all; and man, his real creator, after having unknowingly extracted him from the void, bowed down before him, worshipped him, and avowed himself his creature and his slave. Christianity is precisely the religion _par excellence_, because it exhibits and manifests, to the fullest extent, the very nature and essence of every religious system, which is _the impoverishment, enslavement, and annihilation of humanity for the benefit of divinity_.
