I have some difficulties in understanding the meaning of this excerpt from The Book of Lost Things:
David was aware of a change in the room as soon as he began to fill the empty spaces on the shelves, the newer books looking and sounding uneasy beside these other works from the past. Their appearance was intimidating, and they spoke to David in dusty, rumbling tones. The older books were bound in calfskin and leather, and some of them contained knowledge that had long been forgotten, or that was found to be incorrect as science and the process of discovery uncovered new truths. The books that held this old knowledge had never come to terms with this relegation of their worth. They were now lower than stories, for stories were intended, at some level, to be made up and untrue, but these other books had been born for greater things. Men and women had worked hard on their creation, filling them with the sum total of all that they knew and all that they believed about the world. That they were misguided, and the assumptions they made were now largely worthless, was almost impossible for the books to bear.
I understand that the author plays with the idea of talking books with personalities. However, I wonder, is there a hierarchy made between fiction and non-fiction here? Is it ironic when it is said "these other books had been born for greater things"? I don't really understand the point of mentioning these old books.
