he must have solid guarantees of some sort

When Totski had approached the general with his request for friendly counsel as to a marriage with one of his daughters, he had made a full and candid confession. He had said that he intended to stop at no means to obtain his freedom; even if Nastasia were to promise to leave him entirely alone in future, he would not (he said) believe and trust her; words were not enough for him; he must have solid guarantees of some sort. So he and the general determined to try what an attempt to appeal to her heart would effect. Having arrived at Nastasia's house one day, with Epanchin, Totski immediately began to speak of the intolerable torment of his position. He admitted that he was to blame for all, but candidly confessed that he could not bring himself to feel any remorse for his original guilt towards herself, because he was a man of sensual passions which were inborn and ineradicable, and that he had no power over himself in this respect; but that he wished, seriously, to marry at last, and that the whole fate of the most desirable social union which he contemplated, was in her hands; in a word, he confided his all to her generosity of heart. General Epanchin took up his part and spoke in the character of father of a family; he spoke sensibly, and without wasting words over any attempt at sentimentality, he merely recorded his full admission of her right to be the arbiter of Totski's destiny at this moment. He then pointed out that the fate of his daughter, and very likely of both his other daughters, now hung upon her reply. To Nastasia's question as to what they wished her to do, Totski confessed that he had been so frightened by her, five years ago, that he could never now be entirely comfortable until she herself married. He immediately added that such a suggestion from him would, of course, be absurd, unless accompanied by remarks of a more pointed nature. He very well knew, he said, that a certain young gentleman of good family, namely, Gavrila Ardalionovitch Ivolgin, with whom she was acquainted, and whom she received at her house, had long loved her passionately, and would give his life for some response from her.
