Before entering upon the subject-matter of these new memoirs, I must explain an hypothesis which will undoubtedly seem strange, but in the absence of which it is impossible for me to proceed intelligibly: I mean the hypothesis of a God.

To suppose God, it will be said, is to deny him. Why do you not affirm him?

Is it my fault if belief in Divinity has become a suspected opinion; if the bare suspicion of a Supreme Being is already noted as evidence of a weak mind; and if, of all philosophical Utopias, this is the only one which the world no longer tolerates? Is it my fault if hypocrisy and imbecility everywhere hide behind this holy formula?

Let a public teacher suppose the existence, in the universe, of an unknown force governing suns and atoms, and keeping the whole machine in motion. With him this supposition, wholly gratuitous, is perfectly natural; it is received, encouraged: witness attraction -- an hypothesis which will never be verified, and which, nevertheless, is the glory of its originator. But when, to explain the course of human events, I suppose, with all imaginable caution, the intervention of a God, I am sure to shock scientific gravity and offend critical ears: to so wonderful an extent has our piety discredited Providence, so many tricks have been played by means of this dogma or fiction by charlatans of every stamp! I have seen the theists of my time, and blasphemy has played over my lips; I have studied the belief of the people, -- this people that Brydaine called the best friend of God, -- and have shuddered at the negation which was about to escape me. Tormented by conflicting feelings, I appealed to reason; and it is reason which, amid so many dogmatic contradictions, now forces the hypothesis upon me. A priori dogmatism, applying itself to God, has proved fruitless: who knows whither the hypothesis, in its turn, will lead us?

I will explain therefore how, studying in the silence of my heart, and far from every human consideration, the mystery of social revolutions, God, the great unknown, has become for me an hypothesis, -- I mean a necessary dialectical tool.
