Why logical arguments for Messengers don't work.

[Neo-Scholastic]

Mystic, you seem to be suggesting that the apparent perfection of a particular artifact, in your example a book, can only be explained as Divine. For the sake of argument, I'll assume that the Koran is the best example of poetic expression in all of human history. From my perspective many of the greatest human achievements seem incredible such as, the Sistine Chapel, the collected works of Shakespeare, the music of J. S. Bach and Mozart. Yet each of these is a testament to the amazing capacities of truly remarkable people.
