“Wherever there is a design that is highly successful in a broad range of similar environments, it is apt to emerge again and again, independently - the phenomenon known in biology as convergent evolution. I call these designs 'good tricks.'”

“We adore babies because they're so cute. And, of course, we are amused by jokes because they are funny. This is all backwards. It is. And Darwin shows us why.”

“The secret of happiness is: Find something more important than you are and dedicate your life to it.”

“In short, we need to recover the courage we celebrate in our heroes, and in particular, the courage to tolerate, for the sake of a free society, a level of risk we hardly ever imagined in the past.”
