I really disliked Philadelphia society - really, deeply disliked it. I spent a lot of my teenage years writing poetry attacking it.

Look at the great tradition of Western political philosophy. Those people were all immersed in revolutionary movements. Most weren't career academics - often, they were too radical to be accepted in the academy. Rousseau's books were banned. Jeremy Bentham and John Stuart Mill couldn't hold academic positions because they were atheists.

At Chicago I offer a course on Emotion, Reason and the Law that law students just love. But I am not there as a lawyer, my job is to teach philosophy.

When I was younger, I wasn't concentrating on good days. I was managing a career and trying to have a good year.

My father was a lawyer and to my best knowledge nobody in my family before had interest in science.
