“Refuse to be a subject of ignorance people. Do what can change their minds for good. Because, in the champions of them, lies no comfort of humanity.”

Used in the Apple "Think Different" marketing campaign and sometimes attributed to Kerouac on the internet, perhaps because it evokes his famous quote from On the Road: "The only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn, like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes "Awww!"" The original script was actuality written by Rob Siltanen with participation of Lee Clow. In "The Real Story Behind Apple's 'Think Different' Campaign" in Forbes (14 December 2011) http://www.forbes.com/sites/onmarketing/2011/12/14/the-real-story-behind-apples-think-different-campaign/ Rob Siltanen states: "I wrote everything..." "I shared my scripts with Lee, and he thought they were good. He made a couple tweaks..."

Context: "When you stopped believing in God, did you stop believing in good and evil?"
"No. But I stopped believing there was a power of good and a power of evil that were outside us. And I came to believe that good and evil are names for what people do, not for what they are. All we can say is that this is a good deed, because it helps someone, or that's an evil one, because it hurts them. People are too complicated to have simple labels."
