Since the moment when, at the sigh of his beloved and dying brother, Levin for the first time looked at the questions of life and death in the light of the new convictions, as he called them...he had been less horrified by death than by life without the least knowledge of whence it came, what it is for, why, and what it is. Organisms, their destruction, the indestructibility of matter, the law of the conservation of energy, development--the terms that had superseded these beliefs--were very useful for mental purposes; but they gave no guidance for life, and Levin suddenly felt like a person who has exchanged a thick fur coat fora muslin garment and who, being out in the frost for the first time, becomes clearly convinced, not by arguments, but with the whole of his being that he is as good as naked and that he must inevitably perish miserably. From that moment, without thinking about it and though he continued living as he had done heretofore, Levin never ceased to feel afraid of his ignorance...What astounded and upset him most in his connection, was that the majority of those in his set and of his age, did not see anything to be distressed about, and were quite contented and tranquil. So that, besides the principal question, Levin was tormented by other questions: were these people sincere? Were they not pretending? Or did they understand, possibly in some different or clearer way than he, the answers science gives to the questions he was concerned with?
