Thanks to the manner in which he regarded Nastasia’s mental and moral condition, the prince was to some extent freed from other perplexities. She was now quite different from the woman he had known three months before. He was not astonished, for instance, to see her now so impatient to marry him⁠—she who formerly had wept with rage and hurled curses and reproaches at him if he mentioned marriage! “It shows that she no longer fears, as she did then, that she would make me unhappy by marrying me,” he thought. And he felt sure that so sudden a change could not be a natural one. This rapid growth of self-confidence could not be due only to her hatred for Aglaya. To suppose that would be to suspect the depth of her feelings. Nor could it arise from dread of the fate that awaited her if she married Rogojin. These causes, indeed, as well as others, might have played a part in it, but the true reason, Muishkin decided, was the one he had long suspected⁠—that the poor sick soul had come to the end of its forces. Yet this was an explanation that did not procure him any peace of mind. At times he seemed to be making violent efforts to think of nothing, and one would have said that he looked on his marriage as an unimportant formality, and on his future happiness as a thing not worth considering.
