“I don’t own many books. So, I collected books in great numbers when I was an undergraduate, mostly history of economic thought. I thought I would build up this incredible collection of the great economics masterworks. But then I started moving around, and then I moved to Germany for a year and I’m, like, ‘This is not going to work.’ So, what I will do–there’s some economic historians in my department. If I get a history book, I will give it to them because I know they won’t necessarily read it. They’ll use it or not use it for reference. And I don’t feel I’m tricking them into reading a book. But I would be very reluctant to give you a book, Russ. Not that I don’t love you or like you, or both, but I would feel that you would feel obliged to read the book. Correct?

It is immoral to give away books unless you truly feel the recipient should read them!”
