“I am a mathematician, sir. I never permit myself to think.”

“I'm afraid I can't explain myself, sir. Because I am not myself, you see?”

“I shall never permit myself to stoop so low as to hate any man. ”

“You think my gait 'spasmodic' - I am in danger - Sir - You think me 'uncontrolled' - I have no Tribunal.”

“It occurs to me to devise mental tests on myself to see if I am who I think I am, but then I think, “I am who I think I am, or I probably am, and a test I conceive and answer about myself isn’t a way to test if I’m another person pretending to be me, because no matter how I answer I’ll answer like myself, thus falsely proving to myself that I am who I think I am.” No, what I need is for my clone to create and administer the test.”

“Now I am depressed myself,' I said. 'That's why I never think about these things. I never think and yet when I begin to talk I say the things I have found out in my mind without thinking.”
