Of course he knew what a book was, but he had never used an encyclopedia.
I am not a Luddite. I believe the Internet is a great resource, but it should not come at the cost of books. My student, for example, did some research in the encyclopedia, but then something miraculous happened. He began turning the pages of the book and reading about other subjects that began with the letter D. He was absorbing random information from a book! This simple act is almost impossible to do on the Internet where you must search for specific subject matter.
