“The horrors of [Vivisection] have supplanted the solemnity, the thrilling fascination, of the old unetherized operation upon the human sufferer. Their recorded phenomena, stored away by the physiological inquisitor on dusty shelves, are mostly of as little present use to man as the knowledge of a new comet or of a tungstate of zirconium: perhaps to be confuted the next year, perhaps to remain as fixed truth of immediate value, — contemptibly small compared with the price paid for it in agony and torture.”

By the Waters of Babylon (1937)
Context: It is better the truth should come little by little. I have learned that, being a priest. Perhaps, in the old days, they ate knowledge too fast.
Nevertheless, we make a beginning. it is not for the metal alone we go to the Dead Places now — there are the books and the writings. They are hard to learn. And the magic tools are broken — but we can look at them and wonder. At least, we make a beginning. And, when I am chief priest we shall go beyond the great river. We shall go to the Place of the Gods — the place newyork — not one man but a company. We shall look for the images of the gods and find the god ASHING and the others — the gods Lincoln and Biltmore and Moses. But they were men who built the city, not gods or demons. They were men. I remember the dead man's face. They were men who were here before us. We must build again.

Part 2: Metaphysical Rebellion
The Rebel (1951)
Context: Alyosha can, in fact, treat Ivan with compassion as a "real simpleton." The latter only made aa attempt at self-control and failed. Others will appear, with more serious intentions, who, on the basis of the same despairing nihilism, will insist on ruling the world. These are the Grand Inquisitors who imprison Christ and come to tell Him that His method is not correct, that universal happiness cannot be achieved by the immediate freedom of choosing between good and evil, but by the domination and unification of the world. The first step is to conquer and rule. The kingdom of heaven will, in fact, appear on earth, but it will be ruled over by men — a mere handful to begin with, who will be the Cassars, because they were the first to understand — and later, with time, by all men. The unity of all creation will be achieved by every possible means, since everything is permitted. The Grand Inquisitor is old and tired, for the knowledge he possesses is bitter. He knows that men are lazy rather than cowardly and that they prefer peace and death to the liberty of discerning between good and evil. He has pity, a cold pity, for the silent prisoner whom history endlessly deceives. He urges him to speak, to recognize his misdeeds, and, in one sense, to approve the actions of the Inquisitors and of the Caesars. But the prisoner does not speak.
