Rogojin roared with laughter. He laughed as though he were in a sort of fit. It was strange to see him laughing so after the sombre mood he had been in just before.
"Oh, I like that! That beats anything!" he cried convulsively, panting for breath. "One is an absolute unbeliever; the other is such a thorough--going believer that he murders his friend to the tune of a prayer! Oh, prince, prince, that's too good for anything! You can't have invented it. It's the best thing I've heard!"
"Next morning I went out for a stroll through the town," continued the prince, so soon as Rogojin was a little quieter, though his laughter still burst out at intervals, "and soon observed a drunken-looking soldier staggering about the pavement. He came up to me and said, 'Buy my silver cross, sir! You shall have it for fourpence--it's real silver.' I looked, and there he held a cross, just taken off his own neck, evidently, a large tin one, made after the Byzantine pattern. I fished out fourpence, and put his cross on my own neck, and I could see by his face that he was as pleased as he could be at the thought that he had succeeded in cheating a foolish gentleman, and away he went to drink the value of his cross. At that time everything that I saw made a tremendous impression upon me. I had understood nothing about Russia before, and had only vague and fantastic memories of it. So I thought, 'I will wait awhile before I condemn this Judas. Only God knows what may be hidden in the hearts of drunkards.'
"Well, I went homewards, and near the hotel I came across a poor woman, carrying a child--a baby of some six weeks old. The mother was quite a girl herself. The baby was smiling up at her, for the first time in its life, just at that moment; and while I watched the woman she suddenly crossed herself, oh, so devoutly! 'What is it, my good woman I asked her. (I was never but asking questions then!) Exactly as is a mother's joy when her baby smiles for the first time into her eyes, so is God's joy when one of His children turns and prays to Him for the first time, with all his heart!' This is what that poor woman said to me, almost word for word; and such a deep, refined, truly religious thought it was--a thought in which the whole essence of Christianity was expressed in one flash--that is, the recognition of God as our Father, and of God's joy in men as His own children, which is the chief idea of Christ. She was a simple country-woman--a mother, it's true-- and perhaps, who knows, she may have been the wife of the drunken soldier!
"Listen, Parfen; you put a question to me just now. This is my reply. The essence of religious feeling has nothing to do with reason, or atheism, or crime, or acts of any kind--it has nothing to do with these things--and never had. There is something besides all this, something which the arguments of the atheists can never touch. But the principal thing, and the conclusion of my argument, is that this is most clearly seen in the heart of a Russian. This is a conviction which I have gained while I have been in this Russia of ours. Yes, Parfen! there is work to be done; there is work to be done in this Russian world! Remember what talks we used to have in Moscow! And I never wished to come here at all; and I never thought to meet you like this, Parfen! Well, well--good-bye--good-bye! God be with you!"
"Lef Nicolaievitch!" cried Parfen, before he had reached the next landing. "Have you got that cross you bought from the soldier with you?"
A new fancy! The prince reflected, and then mounted the stairs once more. He pulled out the cross without taking it off his neck.
Parfen was silent. With sad surprise the prince observed that the look of distrust, the bitter, ironical smile, had still not altogether left his newly-adopted brother's face. At moments, at all events, it showed itself but too plainly,
At last Rogojin took the prince's hand, and stood so for some moments, as though he could not make up his mind. Then he drew him along, murmuring almost inaudibly,
An old woman opened to them and bowed low to Parfen, who asked her some questions hurriedly, but did not wait to hear her answer. He led the prince on through several dark, cold-looking rooms, spotlessly clean, with white covers over all the furniture.
