“Your race is appallingly alone in its world. No other mammalian species. No other ambisexual species. No animal intelligent enough even to domesticate as pets. It must color your thinking, this uniqueness. I don’t mean scientific thinking only, though you are extraordinary hypothesizers … But philosophically, emotionally: to be so solitary, in so hostile a world: it must affect your entire outlook.”

— Ursula K. Le Guin, The Left Hand of Darkness

“For a couple of minutes, his head bowed in an expression of mental effort, he stood motionless with the revolver in his hands and considered. ‘Of course,’ he said to himself, as if a logical, continuous and clear train of thought had brought him to an unquestionable conclusion. In fact, this ‘of course’ that he found so convincing was only the consequence of a repetition of exactly the same round of memories and notions that he had already gone through a dozen times within the hour. It was the same memory of happiness lost for ever, the same notion of the meaninglessness of everything he saw ahead of him in life, the same consciousness of his humiliation.”

— Leo Tolstoy, Anna Karenina
