I go to live in Maine for the summer. Without computer, and without the telephone service we are mercifully without the faxes and e-mails. So it's really about two and a half months that I'll feel like I can recover some silence in my life...which is so hard to find.

Human beings consider themselves satisfied only compared to some other condition. A man who has owned nothing but a bicycle all of his life feels suddenly wealthy the moment he buys an automobile...But this happy sensation wears off. After a while the car becomes just another thing that he owns. Moreover, when his neighbor next door buys two cars, in an instant our man feels wretchedly poor and deprived.

In a world in which time is a circle, every handshake, every kiss, every birth, every word, will be repeated precisely.

We're plugged in 24 hours a day now. We're all part of one big machine, whether we are conscious of that or not. And if we can't unplug from that machine, eventually we're going to become mindless.

I value my correspondence with writers...I was in New York and had lunch with Oliver Sachs and compared notes with him - he is someone I really like. I love staying in written correspondence with some writers. That's enough for me.

Except for a God who sits down after the universe begins, all other gods conflict with the assumptions of science.

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.
