It's the Platonic philosophy in The Republic that philosophers should lead the country.

For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness.

I think e-mail is representative of our fast food mentality in the United States, where everything has gotten faster and faster, and we're required to respond to inputs more quickly with less time for thought and reflection. I believe that we need to slow down.

In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.

I think people all over the institution recognize that different ways of understanding are valuable. Artists may think in a different way than biologists or chemists, but you can learn something from that. It is true that the arts at MIT don't have the same amount of funding or same status as the sciences or engineering.

If I were not a writer, I would spend more time doing the things that I am already doing, which include doing research in physics, teaching, and running a nonprofit organization with a mission to empower women in Cambodia.
