"To understand animal thinking you've got to get away from a language. See my mind works like Google for images. You put in a key word; it brings up pictures. See language for me narrates the pictures in my mind. When I work on designing livestock equipment I can test run that equipment in my head like 3-D virtual reality. In fact, when I was in college I used to think that everybody was able to do that. And language just sort of, you know, gives an opinion. Like, oh, that's a good idea or oh, I just figured out how to design that."
