warnings that the aurthor is trying to get across

The warnings that the author is trying to get across to us about the book is that the things that you read can give us info on things you want to know. The author is telling us if we didn't have any books we wouldn't know that much because when someone finds something new they tell people and they write it down so people can see it around the world. If we didn't have books how can we learn things in school if we don't have books, If we don't have books who can teach the teacher. If the teacher don't learn we don't learn and then the world would be crazy. This is what i think his is trying to warn us.
