The character Tanner's retort to Ramsden's contention that Tanner is an impudent man. Excerpt from George Bernard Shaw's play - Man and Superman.

"We live in an atmosphere of shame. We are ashamed of everything that is real about us; ashamed of ourselves, of our relatives, of our incomes, of our accents, of our opinions, of our experience, just as we are ashamed of our naked skins. Good Lord, my dear Ramsden, we are ashamed to walk, ashamed to ride in an omnibus, ashamed to hire a hansom instead of keeping a carriage, ashamed of keeping one horse instead of two and a groom-gardener instead of a coachman and footman. The more things a man is ashamed of, the more respectable he is. Why, you're ashamed to buy my book, ashamed to read it: the only thing you're not ashamed of is to judge me for it without having read it; and even that only means that you're ashamed to have heterodox opinions."

"I am only the most impudent person you've ever met. That's your notion of a thoroughly bad character. When you want to give me a piece of your mind, you ask yourself, as a just and upright man, what is the worst you can fairly say of me. Thief, liar, forger, adulterer, perjurer, glutton, drunkard? Not one of these names fit me. You have to fall back on my deficiency in shame. Well, I admit it. I even congratulate myself; for if I were ashamed of my real self, I should cut as stupid a figure as any of the rest of you. Cultivate a little impudence, Ramsden; and you will become quite a remarkable man."
