Many years ago, when I was a junior professor at Yale, I cold-called a colleague in the anthropology department for assistance with a project I was working on. I didn’t know anything about the guy; I just selected him because he was young, and therefore, I figured, more likely to agree to talk.
Five minutes into our lunch, I realized that I was in the presence of a genius. Not an extremely intelligent person—a genius. There’s a qualitative difference. The individual across the table seemed to belong to a different order of being from me, like a visitor from a higher dimension. I had never experienced anything like it before. I quickly went from trying to keep up with him, to hanging on for dear life, to simply sitting there in wonder.
