Knowing we will not agree, I will simply leave it that it was the first book on Gutenberg printing press, and that I think we can both agree made books much more widely available. Additionally, I think that must people on this site have more than likely had some logic and critical thinking studies, myself included, and that it is ok to disagree on some things. However, on the logic side, if Heaven is real and there is but one way to get there and not many, only those on that way will get there. If it is real and there are many ways, it doesn't matter what one you pick. If it is not real, then it also doesn't matter. I know if someone wants to hear logical discussions there are apologetics and debaters out there that are good to listen to. With the main thread here, I appreciate libraries and librarians greatly, especially in an age where so much is kept in a mutable form vs the hard copy. I would say that I hope most people have a worldview that they can express, and that it should morph with a deeper understanding of the world as you mature.
