This is a straight quote from Nassim Taleb (Fooled by Randomness, Black Swan, Antifragile)
A private library is not an ego-boosting appendage but a research tool. Read books are far less valuable than unread ones. The library should contain as much of what you do not know as your financial means, mortgage rates, and the currently tight real-estate market allows you to put there. You will accumulate more knowledge and more books as you grow older, and the growing number of unread books on the shelves will look at you menacingly. Indeed, the more you know, the larger the rows of unread books. Let us call this collection of unread books an antilibrary.
It’s a excellent reflection.
My antilibrary is of Alexandrian proportions.
But Taleb’s ones are in the library.
I am convinced that the books in my library talk to each other during the night and decide between them what ideas I should pursue the next day. There is a nocturnal conspiracy around me. I just know.
