On the subject of morals and text books: In Surely You're Joking Mr. Feynman he talks about serving on a committee to select a new text book for a school.
"""
A few days later a guy from the book depository called me up and said, "We're ready to send you the books, Mr. Feynman; there are three hundred pounds."
I was overwhelmed.
"It's all right, Mr. Feynman; we'll get someone to help you read them."
I couldn't figure out how you do that: you either read them or you don't read them. I had a special bookshelf put in my study downstairs (the books took up seventeen feet), and began reading all the books that were going to be discussed in the next meeting. We were going to start out with the elementary schoolbooks.
"""
So right away we see the text book business is bullshit because the peddler has an established business of helping others review the books, but as Feynman asks, how do you actually do that? How do you help someone read and review a text book?
Later:
"""
Then I came to my first meeting. The other members had given some kind of ratings to some of the books, and they asked me what my ratings were. My rating was often different from theirs, and they would ask, "Why did you rate that book low?" I would say the trouble with that book was this and this on page so-and-so – I had my notes.
They discovered that I was kind of a goldmine: I would tell them, in detail, what was good and bad in all the books; I had a reason for every rating.
I would ask them why they had rated this book so high, and they would say, "Let us hear what you thought about such and such a book." I would never find out why they rated anything the way they did. Instead, they kept asking me what I thought.
We came to a certain book, part of a set of three supplementary books published by the same company, and they asked me what I thought about it.
I said, "The book depository didn't send me that book, but the other two were nice."
Someone tried repeating the question: "What do you think about that book?"
"I said they didn't send me that one, so I don't have any judgment on it."
The man from the book depository was there, and he said, "Excuse me; I can explain that. I didn't send it to you because that book hadn't been completed yet. There's a rule that you have to have every entry in by a certain time, and the publisher was a few days late with it. So it was sent to us with just the covers, and it's blank in between. The company sent a note excusing themselves and hoping they could have their set of three books considered, even though the third one would be late."
It turned out that the blank book had a rating by some of the other members! They couldn't believe it was blank, because [the book] had a rating. In fact, the rating for the missing book was a little bit higher than for the two others. The fact that there was nothing in the book had nothing to do with the rating.
