“But I believe there is no difference between those who are called courageous and those who are branded craven than that the second are fearful before the danger and the first after it. The coward is a coward, then, because he has brought his fear with him; persons we think cowardly will sometimes amaze us by their bravery, if they have had no forewarning of their danger.”

“Seeing him brought in, has, I think, saved me from losing my mind; for that I do not thank him-sanity, after all is only reason applied to human affairs, and when this reason, applied over years, has resulted in disaster, destruction, despair, misery, starvation, and rot, the mind is correct to abandon it. This decision to discard reason, I see now, is not the last but the first reasonable act; and this insanity we are taught to fear consists in nothing but responding naturally and instinctively rather than with the culturally acquired, mannered thing called reason; an insane man talks nonsense because like a bird or a cat he is too sensible to talk sense.”

“[T]he very existence of such powers argues a counterforce. We call powers of the first kind dark, though they may use a species of deadly light... and we call those of the second kind bright, though I think that they may at times employ darkness, as a good man nevertheless draws the curtains of his bed to sleep. Yet there is truth to the talk of darkness and light, because it shows plainly that one implies the other. The tale I read to little Severian said that the universe was but a long word of the Increate's. We, then, are syllables of that word. But the speaking of any word is futile unless there are other words, words that are not spoken. If a beast has but one cry, the cry tells nothing; and even the wind has a multitude of voices, so that those who sit indoors may hear it and know if the weather is tumultuous or mild. The powers we call dark seem to me to be the words the Increate did not speak... and these words must be maintained in a quasi-existence, if the other word, the word spoken is to be distinguished. What is not said can be important - but what is said is more important... And if the seekers after dark things find them, may not the seekers after bright find them as well? And are they not more apt to hand their wisdom on?”

“The brown book I carry says there is nothing stranger than to explore a city wholly different from all those one knows, since to do so is to explore a second and unsuspected self. I have found a thing stranger: to explore such a city only after one has lived in it for some time without learning anything of it.”

“She was staring at the low ceiling, and I had the feeling that there was another Severian there, the kind and even noble Severian who existed only in Dorcas’s mind. All of us, I suppose, when we think we are talking most intimately to someone else, are actually addressing an image we have of the person to whom we believe we speak.”

“He shook his head. "Everyone fears me, except you, Latro. When a man is respected, no one wants to plant a dagger in his back. When he is feared, everyone thinks upon it, and tests the point.”

“I have never had much need for companionship, unless it was the companionship of someone I could call a friend. Certainly I have seldom wished the conversation of strangers or the sight of strange faces. I believe rather that when I was alone I felt I had in some fashion lost my individuality; to the thrush and the rabbit I had been not Severian, but Man. The many people who like to be utterly alone, and particularly to be utterly alone in a wilderness, do so, I believe, because they enjoy playing that part. But I wanted to be a particular person again, and so I sought the mirror of other persons, which would show me that I was not as they were.”
