Alan Sillitoe said this quote

I'm a human being and I've got thoughts and secrets and bloody life inside me that he doesn't know is there, and he'll never know what's there because he's stupid. I suppose you'll laugh at this, me saying the governor's a stupid bastard when I know hardly how to write and he can read and write and add-up like a professor. But what I say is true right enough. He's stupid, and I'm not, because I can see further into the likes of him than he can see into the likes of me.
