“I wanted to find out then and quickly whether I was a louse like everybody else or a man. Whether I can step over barriers or not, whether I dare stoop to pick up or not, whether I am a trembling creature or whether I have the right...F”

“[The Devil] And after all, who knows whether proof of the devil is also proof of God? I want to join an idealist society and form an opposition within it: 'I'm a realist,' I'll say, 'not a materialist,' heh, heh!”

“…have you noticed, Rodion Romanovitch, that in our Petersburg circles, if two clever men meet who are not intimate, but respect each other, like you and me, it takes them half an hour before they can find a subject for conversation – they are dumb, they sit opposite each other and feel awkward? Everyone has subjects of conversation, ladies for instance…people in high society always have their subjects of conversation, c’est de rigueur; but people of the middle sort like us, thinking people that is, are always tongue-tied and awkward. What is the reason of it? Whether it is the lack of public interest, or whether it is we are so honest we don’t want to deceive one another, I don’t know. What do you think?”

“For what is it you and I are trying to do now? What I'm trying to do is to attempt to explain to you as quickly as possible the most important thing about me, that is to say, what sort of man I am, what I believe in what I hope for - that's it isn't it? And that's why I declare that I accept God plainly and simply. But there's this that has to be said: if God really exists and if he really has created the world, then, as we all know, he created it in accordance with the Euclidean geometry, and he created the human mind with the conception of only the three dimensions of space. And yet there have been and there still are mathematicians and philosophers, some of them indeed men of extraordinary genius, who doubt whether the whole universe, or, to put it more wildly, all existence was created only according to Euclidean geometry and they even dare to dream that two parallel lines which, according to Euclid can never meet on earth, may meet somewhere in infinity. I, my dear chap, have come to the conclusion that if I can't understand even that, then how can I be expected to understand about God? I humbly admit that I have no abilities for settling such questions. And I advise you too, Aloysha, my friend, never to think about it, and least of all about whether there is a God or not. All these problems which are entirely unsuitable to a mind created with the idea of only three dimensions. And so I accept God, and I accept him not only without reluctance, but what's more, I accept his divine wisdom and his purpose- which are completely beyond our comprehension.”

“I know that my youth will triumph over everything - every disillusionment, every disgust with life. I’ve asked myself many times whether there is in in the world any despair that would overcome this frantic and perhaps unseemly thirst for life in me, and I've come to the conclusion that there isn't...”

“Do you know I've been sitting here thinking to myself: that if I didn't believe in life, if I lost faith in the woman I love, lost faith in the order of things, were convinced in fact that everything is a disorderly, damnable, and perhaps devil-ridden chaos, if I were struck by every horror of man's disillusionment -- still I should want to live. Having once tasted of the cup, I would not turn away from it till I had drained it! At thirty though, I shall be sure to leave the cup even if I've not emptied it, and turn away -- where I don't know. But till I am thirty I know that my youth will triumph over everything -- every disillusionment, every disgust with life. I've asked myself many times whether there is in the world any despair that could overcome this frantic thirst for life. And I've come to the conclusion that there isn't, that is until I am thirty.”

“Yes, Lise. You see, your question whether we do not despise that unhappy man by dissecting his soul was the question of a person who has suffered a lot. I'm afraid I don't know how to put it properly, but a person to whom such questions occur is himself capable of suffering.”
