I realized that you could formulate theories about human and social phenomena in language and pictures and whatever you wanted on the computer, and you didn't have to go through this straitjacket, adding a lot of numbers.

I started off thinking that maybe the social sciences ought to have the kinds of mathematics that the natural sciences had. That works a little bit in economics because they talk about costs, prices and quantities of goods.

When computers came along, I felt for the first time that I had the proper tools for the kind of theoretical work I wanted to do. So I moved over to that, and that got me into psychology.
