Sonia's face suddenly changed; a tremor passed over it. She looked at him with unutterable reproach, tried to say something, but could not speak and broke into bitter, bitter sobs, hiding her face in her hands.

"You say Katerina Ivanovna's mind is unhinged; your own mind is unhinged," he said after a brief silence.

Five minutes passed. He still paced up and down the room in silence, not looking at her. At last he went up to her; his eyes glittered. He put his two hands on her shoulders and looked straight into her tearful face. His eyes were hard, feverish and piercing, his lips were twitching. All at once he bent down quickly and dropping to the ground, kissed her foot. Sonia drew back from him as from a madman. And certainly he looked like a madman.

"What are you doing to me?" she muttered, turning pale, and a sudden anguish clutched at her heart.

He stood up at once.

"I did not bow down to you, I bowed down to all the suffering of humanity," he said wildly and walked away to the window. "Listen," he added, turning to her a minute later. "I said just now to an insolent man that he was not worth your little finger... and that I did my sister honour making her sit beside you."

"Ach, you said that to them! And in her presence?" cried Sonia, frightened. "Sit down with me! An honour! Why, I'm... dishonourable.... Ah, why did you say that?"

"It was not because of your dishonour and your sin I said that of you, but because of your great suffering. But you are a great sinner, that's true," he added almost solemnly, "and your worst sin is that you have destroyed and betrayed yourself _for nothing_. Isn't that fearful? Isn't it fearful that you are living in this filth which you loathe so, and at the same time you know yourself (you've only to open your eyes) that you are not helping anyone by it, not saving anyone from anything? Tell me," he went on almost in a frenzy, "how this shame and degradation can exist in you side by side with other, opposite, holy feelings? It would be better, a thousand times better and wiser to leap into the water and end it all!"

"But what would become of them?" Sonia asked faintly, gazing at him with eyes of anguish, but not seeming surprised at his suggestion.
