We - we spend a lot of time, scholarly time, thinking about love and sex, but very little about the - the kind of joy that can take over a crowd of people or a group of people, in festivity, in ecstatic ritual of some kind, in celebration.

I'm an obsessive. When I get a problem, a question in my mind, it can take me over.

I don't spend a lot of time thinking about myself.

I'm interested in what bonds people together. You know, what brings us together in good ways? And there's not a lot known about that.

I spend shockingly little time thinking about real-world stuff.

When I was 13, I had these episodes where I could just see the world without any words attached to it, without any associations. It was a little bit spooky. A lot of people might have even thought it was pathological. I thought it was interesting.
