Children, who have so much to learn in so short a time, had involved the tendency to trust adults to instruct them in the collective knowledge of our species, and this trust confers survival value. But it also makes children vulnerable to being tricked and adults who exploit this vulnerability should be deeply ashamed.

Math . . . music .. . starry nights . . . These are secular ways of achieving transcendence, of feeling lifted into a grand perspective. It's a sense of being awed by existence that almost obliterates the self. Religious people think of it as an essentially religious experience but it's not. It's an essentially human experience.

He was a sort of philosophical urban gorilla hanging around in the middle of Athens, asking these peculiar questions of everybody - important people, young men, slaves - questions that had to do with ultimately what's the life that's worth living. And Plato was one of the young men who hung around him, a very aristocratic young man, came from a very old, important family.

We become more worthy the more we bend our minds to the impersonal. We become better as we take in the universe, thinking more about the largeness that it is and laugh about the smallness that is us.

I was trained as a philosopher never to put philosophers and their ideas into historical contexts, since historical context has nothing to do with the validity of the philosopher's positions.
