The Brothers Karamazov by Fyodor Dostoyevsky, book V (“Pro and Contra”), chapter 4 (“Rebellion”):
Can you understand why a little creature, who can’t even understand what’s done to her, should beat her little aching heart with her tiny fist in the dark and the cold, and weep her meek unresentful tears to dear, kind God to protect her? Do you understand that, friend and brother, you pious and humble novice? Do you understand why this infamy must be and is permitted? Without it, I am told, man could not have existed on earth, for he could not have known good and evil. Why should he know that diabolical good and evil when it costs so much? Why, the whole world of knowledge is not worth that child’s prayer to dear, kind God’!
…Surely I haven’t suffered simply that I, my crimes and my sufferings, may manure the soil of the future harmony for somebody else. I want to see with my own eyes the hind lie down with the lion and the victim rise up and embrace his murderer. I want to be there when everyone suddenly understands what it has all been for. All the religions of the world are built on this longing, and I am a believer. But then there are the children, and what am I to do about them? That’s a question I can’t answer. For the hundredth time I repeat, there are numbers of questions, but I’ve only taken the children, because in their case what I mean is so unanswerably clear. Listen! If all must suffer to pay for the eternal harmony, what have children to do with it, tell me, please? It’s beyond all comprehension why they should suffer, and why they should pay for the harmony. Why should they, too, furnish material to enrich the soil for the harmony of the future? I understand solidarity in sin among men. I understand solidarity in retribution, too; but there can be no such solidarity with children. And if it is really true that they must share responsibility for all their fathers’ crimes, such a truth is not of this world and is beyond my comprehension. Some jester will say, perhaps, that the child would have grown up and have sinned, but you see he didn’t grow up, he was torn to pieces by the dogs, at eight years old. Oh, Alyosha, I am not blaspheming! I understand, of course, what an upheaval of the universe it will be when everything in heaven and earth blends in one hymn of praise and everything that lives and has lived cries aloud: ‘Thou art just, O Lord, for Thy ways are revealed.’ When the mother embraces the fiend who threw her child to the dogs, and all three cry aloud with tears, ‘Thou art just, O Lord!’ then, of course, the crown of knowledge will be reached and all will be made clear. But what pulls me up here is that I can’t accept that harmony. And while I am on earth, I make haste to take my own measures.
…I don’t want the mother to embrace the oppressor who threw her son to the dogs! She dare not forgive him! Let her forgive him for herself, if she will, let her forgive the torturer for the immeasurable suffering of her mother’s heart. But the sufferings of her tortured child she has no right to forgive; she dare not forgive the torturer, even if the child were to forgive him! And if that is so, if they dare not forgive, what becomes of harmony? Is there in the whole world a being who would have the right to forgive and could forgive? I don’t want harmony. From love for humanity I don’t want it. I would rather be left with the unavenged suffering. I would rather remain with my unavenged suffering and unsatisfied indignation, even if I were wrong. Besides, too high a price is asked for harmony; it’s beyond our means to pay so much to enter on it. And so I hasten to give back my entrance ticket, and if I am an honest man I am bound to give it back as soon as possible. And that I am doing. It’s not God that I don’t accept, Alyosha, only I most respectfully return him the ticket.”
