“I’ve always been very one-sided about science and when I was younger I concentrated almost all my effort on it. I didn’t have time to learn and I didn’t have much patience with what’s called the humanities, even though in the university there were humanities that you had to take. I tried my best to avoid somehow learning anything and working at it. It was only afterwards, when I got older, that I got more relaxed, that I’ve spread out a little bit. I’ve learned to draw and I read a little bit, but I’m really still a very one-sided person and I don’t know a great deal. I have a limited intelligence and I use it in a particular direction.”
