-But rational thoughts lead only to rational thoughts, whereas irrational thoughts lead to new experiences.

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.

The tragedy of this world is that everyone is alone. For a life in the past cannot be shared with the present.

My second novel, "Good Benito", was not finished. I wished that I had spent another year with it.

Events, once happened, lose reality, alter with a glance, a storm, a night. In time, the past never happened. But who could know? Who could know that the past is not as solid as this instant.

Most people have learned to live in the moment. The argument goes that if the past has uncertain effect on the present, there is no need to dwell on the past. And if the present has little effect on the future, present actions need not be weighed for their consequence. Rather, each act is an island in time, to be judged on its own. ... It is a world of impulse. It is a world of sincerity. It is a world in which every word spoken speaks just to that moment, every glance given has only one meaning.

I consider myself a spiritual atheist. I certainly believe there are forces bigger than ourselves, and that we should be searching, individually, for meaning in our lives. But I don't believe there's a supreme being, an intelligence that created everything.
