Seriously: It's pretty much the same: He's got his interpretation - no matter if it something he came up with all alone, or if he read it somewhere in another book... and in most cases, books read at school are taken apart and analyzed into pieces, until nothing is left of them... a relation with a book is a personal relation... you can give hints, and there may be a generally true background, but that background doesn't necessarily matter to you. It's what the book tells

A book in which you found something somebody else advised you to find may be a Pulitzer prize winner and (objectively seen) a great book - but to you, it's worthless. However, a book in which you find something yourself -maybe even without having searched for it- might be an average book speaking in general terms, but for you it can be a treasure.
