Well, it certainly influences my manner of writing, because I always see Darwin as a model of the act of explanation and of argument; the morality, the ethics of explanation, maybe.

One was Roscoe Gilkey Dickinson. He had got his doctorate in physical chemistry — x-ray crystallography — in 1920. He was the first person to get a Ph.D. from California Institute of Technology. And he was continuing with x-ray crystallography, determining the structure of inorganic crystals. After I had accepted appointment as a graduate student at California Institute of Technology, A.A. Noyes, the head of the division of chemistry and chemical engineering, wrote to say that he had decided I should work with Roscoe Dickinson on determining the structure of crystals. This was really extremely fortunate for me, in my opinion. I don’t think that there was any field that was more suited to my interests, and I don’t really know why Dr. Noyes selected me out of eight or ten new graduate students to do x-ray crystallography. Dickinson had a remarkable mind. He was a very careful investigator and thinker, a very logical thinker. When he was teaching me x-ray crystallography, he also taught me to ask at each stage in the argument, “What assumptions are being made? How reliable is the conclusion that you draw? What chance is there that one of the assumptions you have made is not correct?” “You should recognize,” he said to me, “that there is in almost every investigation a lack of complete rigor. You should understand just how reliable the arguments are that you are presenting.

Very much, because he’s interested in that same kind of process. Bonnard, Matisse, Indian miniature paintings, which he collected. That’s where the light comes from, a spectral relationship within the painting itself.

Well, if I had studied theater, I would not be making the kind of theater that I’m making. My theater came about by living. My first play that had text was written with another 13-year-old young man named Christopher Knowles who spent 11 years of his life in an institution for brain damaged children and was composing text that were arranged mathematically and had to do with geometry. I was fascinated by his mind and the way he was putting words together. Not only was it interesting to hear, but it was also very interesting to see. It wouldn’t be necessarily right for someone else, but for me it was something I was drawn to. It came about by living, not by reading a book.
