“If I were to say what I really think I would be arrested or shut away in a lunatic asylum. Come on, I am sure that it would be the same for everyone.”

Potterism (1921) p.196. https://books.google.com/books?id=9tDSm2WzQxsC&pg=PA196
Context: Jane: What do you think of his book Arthur?
Gideon: I don't think of it. I've had no reason to, particularly. I've not had to review it.... I'm afraid I'm hopeless about novels just now, that's the fact. I'm sick of the form—slices of life served up cold in three hundred pages. Oh, it's very nice; it makes nice reading for people. But what's the use? Except, of course, to kill time for those who prefer it dead. But as things in themselves, as art, they've been ruined by excess. My critical sense is blunted just now. I can hardly feel the difference, though I can see it, between a good novel and a bad one. I couldn't write one, good or bad, to save my life, I know that. And I've got to the stage when I wish other people wouldn't. I wish everyone would shut up, so that we could hear ourselves think...

On reactions to his spray painting the fountain at the free concert he gave in San Francisco, in a Press conference (November 1987) http://www.u2source.com/2007/08/19/bono-press-conference-regarding-graffiti/
Context: It is fair to say that we overreacted a bit. … Its not really worth defending my action, I did it in the spirit of the concert, and I thought I did it in the spirit of the artist's work, and he agreed — but, in fact he didn't own his work anymore, as most artists are prone to, he'd sold it, and the City of San Francisco owned it, and they didn't like what I did at all. … Its a really wild thing, you know, you're in Rock n Roll band — you know, I happen to sell millions of records — people therefore think that makes you a responsible citizen — this is not true. … I think this is one of the more mild actions of tour-madness. … It's the music that is magical with U2. … I don't mind being arrested for putting on a free concert, but I don't want to be arrested for being a vandal. I am a vandal and I do regret what I did. I really do regret it. It was dumb.

Source: Flatland: A Romance of Many Dimensions (1884), PART II: OTHER WORLDS, Chapter 21. How I Tried to Teach the Theory of Three Dimensions to My Grandson, and With What Success
Context: When my Grandson entered the room I carefully secured the door. Then, sitting down by his side and taking our mathematical tablets, — or, as you would call them, Lines — I told him we would resume the lesson of yesterday. I taught him once more how a Point by motion in One Dimension produces a Line, and how a straight Line in Two Dimensions produces a Square. After this, forcing a laugh, I said, "And now, you scamp, you wanted to make me believe that a Square may in the same way by motion 'Upward, not Northward' produce another figure, a sort of extra Square in Three Dimensions. Say that again, you young rascal."At this moment we heard once more the herald's "O yes! O yes!" outside in the street proclaiming the Resolution of the Council. Young though he was, my Grandson — who was unusually intelligent for his age, and bred up in perfect reverence for the authority of the Circles — took in the situation with an acuteness for which I was quite unprepared. He remained silent till the last words of the Proclamation had died away, and then, bursting into tears, "Dear Grandpapa," he said, "that was only my fun, and of course I meant nothing at all by it; and we did not know anything then about the new Law; and I don't think I said anything about the Third Dimension; and I am sure I did not say one word about 'Upward, not Northward', for that would be such nonsense, you know. How could a thing move Upward, and not Northward? Upward and not Northward! Even if I were a baby, I could not be so absurd as that. How silly it is! Ha! ha! ha!"
