Theologians blithely attribute pain to the Fall, ignoring the marvelous design features of the pain system. Every square millimeter of the body has a different sensitivity to pain, so that a speck of dirt may cause excruciating pain in the vulnerable eye whereas it would go unreported on the tough extremities. Internal organs such as the bowels and kidneys have no receptors that warn against cutting or burning—dangers they normally do not face — but show exquisite sensitivity to distention. When organs such as the heart detect danger but lack receptors, they borrow other pain cells ("referred pain"), which is why heart attack victims often report pain in the shoulder or arm. The pain system automatically ramps up hypersensitivity to protect an injured part (explaining why a sore thumb always seems in the way) and turns down the volume in the face of emergencies (soldiers often report no pain from a wound in the course of battle, only afterwards). Pain serves us subliminally as well: sensors make us blink several times a minute to lubricate our eyes and shift our legs and buttocks to prevent pressure sores. Pain is the most effective language the body can use to draw attention to something important.

"A Bulgarian I met lately in Moscow," Ivan went on, seeming not to hear his brother's words, "told me about the crimes committe by Turks and Circassians in all parts of Bulgaria through fear of a general rising of the Slavs. They burn villages, murder, outrage women and children, they nail their prisoners by the ears to the fences, leave them so till morning, and in the morning they hang them — all sorts of things you can't imagine. People talk sometimes of bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel. The tiger only tears and gnaws, that's all he can do. He would never think of nailing people by the ears, even if he were able to do it. These Turks took a pleasure in torturing children, too; cutting the unborn child from the mother's womb, and tossing babies up in the air and catching them on the points of their bayonets before their mother's eyes. Doing it before the mother's eyes was what gave zest to the amusement. Here is another scene that I thought very interesting. Imagine a trembling mother with her baby in her arms, a circle of invading Turks around her. They've planned a diversion; they pet the baby, laugh to make it laugh. They succeed, the baby laughs. At that moment a Turk points a pistol four inches from the baby's face. The baby laughs with glee, holds out his little hand to the pistol, and he pulls the trigger in the baby's face and blows out its brains. Artistic, wasn't it? By the way, Turks are particularly fond of sweet things they say.

But though these external insults, said Demia, from animals, from men, from all the elements, which assault us form a frightful catalogue of woes, they are nothing in comparison of those which arise within ourselves, from the distempered condtion of our mind and body. How many lie under the lingering torment of diseases? Hear the pathetic enumeration of the great poet.

But are such repetitions possible in the universe? Can that be nature's law? And if that is an earth there, is it the same earth as ours? Just the same poor, unhappy, but dear, dear earth, and beloved forever and ever? Arousing like our earth the same poignant love for herself even in the most ungrateful of her children? I kept crying, deeply moved by an uncontrollable, rapturous love for the dear old earth I had left behind... Suddenly a strange feeling of some great and sacred jealousy blazed up in my heart. "How is such a repetition possible and why? I love, I can only love the earth I've left behind, stained with my blood when, ungrateful wretch that I am, I extinguished my life by shooting myself through the heart. But never, never have I ceased to love that earth, and even on the night I parted from it I loved it perhaps more poignantly than ever. Is there suffering on this new earth? On our earth we can truly love only with suffering and through suffering! We know not how to love otherwise. We know no other love. I want suffering in order to love. I want and thirst this very minute to kiss, with tears streaming down my cheeks, the one and only earth I have left behind. I don't want, I won't accept life on any other!

His interest quickened when, in a more emphatic tone, the preacher said that there were some things we could grasp as touching God, and others we could not. There was not doubt as to the existence of good and evil and, as a rule, it was easy to see the difference between them. The difficulty began when we looked into the nature of evil, and among things evil he included human suffering. Thus we had apparently needful pain, and apparently needless pain; we had right that a libertine should be struck down, we see no reason for a child's suffering. And, truth to tell, nothing was more important on earth than a child's suffering, the horror it inspires in us, and the reason we must find to account for it. [H]e might easily have assured them that the child's sufferings would be compensated for by an eternity of bliss awaiting him. But how could he give that assurance when, to tell the truth, he knew nothing about it? For who would dare to assert that eternal happiness can compensate for a single moment's human suffering? He who asserted that would not be a true Christian, a follower of the Master who knew all the pangs of suffering in his body and his soul. No, he, Father Paneloux, would keep faith with that great symbol of all suffering, the tortured body on the Cross; he would stand fast, his back to the wall and face honestly the terrible problem of a child's agony. And he would boldly say to those who listened to his words today, "My brother, a time of testing has come for us all. We must believe everything or deny everything. And who among you, I ask, would dare to deny everything?"
