Man is a spiritual intelligence, who has taken flesh with the object of gaining experience in worlds below the spiritual, in order that he may be able to master and to rule them, and in later ages take his place in the creative and directing hierarchies of the universe.

Like the other great revolutions, an environmental revolution will require sacrifices and lead to enormous gains. It, too, will change the face of the land and human institutions, hierarchies, self-definitions, cultures. It will take centuries. If it happens. There is no guarantee, of course.

My work was fairly theoretical. It was in recursive function theory. And in particular, hierarchies of functions in terms of computational complexity. I got involved in real computers and programming mainly by being - well, I was interested even as I came to graduate school.

I watched a lot of avant-garde films, like Maya Deren's work, and I love film's technical ability to do things that are impossible in real life. It's related to the way collage allows you to manipulate reality and the hierarchies that are inherent in our awful but amazing world.
