“In captivity, in the shed, Pierre had learned, not with his mind, but with his whole being, his life, that man is created for happiness, that happiness is within him, in the satisfying of natural human needs, and that all unhappiness comes not from lack, but from superfluity; but now, in these last three weeks of the march, he had learned a new and more comforting truth - he had learned that there is nothing frightening in the world. He had learned that, as there is no situation in the world in which a man can be happy and perfectly free, so there is no situation in which he can be perfectly unhappy and unfree. He had learned that there is a limit to suffering and a limit to freedom, and that those limits are very close; that the man who suffers because one leaf is askew in his bed of roses, suffers as much as he now suffered falling asleep on the bare, damp ground, one side getting cold as the other warmed up; that when he used to put on his tight ballroom shoes, he suffered just as much as now, when he walked quite barefoot (his shoes had long since worn out) and his feet were covered with sores.”
― Leo Tolstoy, War and Peace
