Steven Levy interviewed Ray Kurzweil about his new role at Google. On the topic of having the courage to follow your convictions:
Levy: What’s the biological basis for that kind of courage? If you had an infinite ability to analyze a brain, could you say, “Oh, here’s where the courage is?”
Kurzweil: It is the neocortex, and people who fill up too much of their neocortex with concern about the approval of their peers are probably not going be the next Einstein or Steve Jobs.
