"[The most important thing for students to know is] to realize that knowledge is for the sake of knowledge. It isn't to get a job. That's the big thing then and today. I tell the students I'm much more experienced now but I strike that right at the very beginning and I keep on talking about it. I don't know if I ever make any headway but they cannot be educated until they try to learn something for the sake of the learning, not for the job....I tell them now, 'I don't educate you at all, you educate yourself. I only put together a direction of work. I tell you things that you couldn't come to by yourself. The rest you have to do, and the rest that you do is your education.' That is to say, out of that you become educated."
