Popper and Nabokov are very different people in some ways - and I'm ready to devote large chunks of my life to both of them. Popper didn't think much of words but thought ideas mattered, and Nabokov didn't think much of ideas, but words mattered, and so on. But both of them had a sense that this is a world of infinite discovery, unending discovery. That quest to discover more in any direction is what I think drives me, and what drives humans, when they're doing the most interesting things.

It seems to me to make as much sense to talk about literature as a large-scale human phenomenon without bringing in evolution as it does to engage in cosmology while you're thinking the universe is still geocentric.

Social media takes time and careful, strategic thought. It doesn't happen by accident.

Scientists, to give them credit, do not think of the humanities in a negative way. It's the bureaucrats who want to cut costs who think, Well, here's something that's not booming at the moment, let's slash it.

Literature and the other arts play with pattern - our brains understand our world by recognizing patterns - and with possibility. The arts harness our sharpest senses, sight and sound, and our richest ways of understanding, in language and narrative. They were our first schools before schools were ever invented. They develop our imaginations, extend our possibilities, and deepen what we can all share.

Art and literature need extreme sociality to a degree that even dolphins don't have. We are the only large mammalian species that has such intense sociality. There are some small mammals that have become eusocial - the mole rats - but that's a different thing. Humans are able to understand one another at very high levels, to cooperate in very large groups. Humans depend on one another in ways that are an absolute precondition to sharing the kinds of information that makes narrative possible.

Everything is humanities. The sciences are a form of the humanities. They involve traditions of inquiry; they involve social engagement with ideas. They do not happen with a naked brain going out and encountering a nonhuman world. And the better we understand ourselves, the better we can do science, as well. So I don't see them - the sciences and the humanities - as being at all different.
