“Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.”
― Fyodor Dostoevsky, The Brothers Karamazov

“If he's honest, he'll steal; if he's human, he'll murder; if he's faithful, he'll deceive.”
― Fyodor Dostoevsky, The Brothers Karamazov

“I love mankind, he said, "but I find to my amazement that the more I love mankind as a whole, the less I love man in particular.”
― Fyodor Dostoyevsky, The Brothers Karamazov
