“PT: You’ve been most associated with issues of outer space. But you have turned very much to a world of inner space, the human mind.
CS: Well, the boundary between space and the earth is purely arbitrary. And I’ll probably always be interested in this planet—it’s my favorite. I’ve written a number of books that have to do with the evolution of humans, human intelligence, human emotions. So it isn’t a new departure for me to be concentrating on humans. Most of the people that I deal with are human. So I’ve had a lot of experience with that.”
Read all of it, well worth it.
