“Experience had taught me that innocence seldom utters outraged shrikes. Guilt does. Innocence is a mighty shield, and the man or woman covered by it, is much more likely to answer calmly: 'My life is blameless. Look into it, if you like, for you will find nothing.' That is the tone of innocence.”

“Cheery was aware that Commander Vimes didn't like the phrase 'The innocent have nothing to fear', believing the innocent had everything to fear, mostly from the guilty but in the longer term even more from those who say things like 'The innocent have nothing to fear'.”

“and yet a child’s utter innocence is but its blank ignorance, and the innocence more or less wanes as intelligence waxes.”

“I, with a deeper instinct, choose a man who compels my strength, who makes enormous demands on me, who does not doubt my courage or my toughness, who does not believe me naïve or innocent, who has the courage to treat me like a woman.”

“The ones who look the most suspicious are likely innocent. It's the ones who look innocent I need to beware.”

“There are no moments more painful for a parent than those in which you contemplate your child's perfect innocence of some imminent pain, misfortune, or sorrow. That innocence (like every kind of innocence children have) is rooted in their trust of you, one that you will shortly be obliged to betray; whether it is fair or not, whether you can help it or not, you are always the ultimate guarantor or destroyer of that innocence.”
