Post Two: Define "Book"

A book is generally recognized as a written piece, printed and bound together on paper.
It's tradition.
When I read a book, or any text for that matter, my purpose is mostly for the words. Ideas, beliefs, and stories are proposed for the reader to weigh and consider through text.
I don't think one can argue that and e-book is not a book. "Book" is 80% of it's name. But, it lacks something that a paperback possesses.
Consider this. Two teachers, teaching the same subject. One of them teaches monotone, right from the textbook, and wears the same color shirt every day. The other teacher uses visual, hands-on examples, has energy in the classroom, and a striking wardrobe. They both teach the same subject, just in different ways.
I prefer a tangible, book that can get torn up and wrinkled. It helps me connect with the writer.
Either way, and e-book is still a book.
