“Curiosity is what separates us from the cabbages. It's accelerative. The more we know, the more we want to know.”

“What makes us want to know the worst? Is it that we tire of preferring to know the best? Does curiosity always hurdle self-interest? Or is it, more simply, that wanting to know the worst is love's favorite perversion.”

“Far more crucial than what we know or do not know is what we do not want to know.”

“Children, be curious. Nothing is worse (I know it) than when curiosity stops. Nothing is more repressive than the repression of curiosity. Curiosity begets love. It weds us to the world. It's part of our perverse, madcap love for this impossible planet we inhabit. People die when curiosity goes. People have to find out, people have to know.”

“It's not always what we don't know that gets in our way; sometimes it's what we think we know that keeps us from learning.”
