Not one-tenth of them

from Walter Benjamin, “Unpacking My Library: A Talk about Book Collecting” (1931), translated by Harry John:

Of all the ways of acquiring books, writing them oneself is regarded as the most praiseworthy method. At this point many of you will remember with pleasure the large library which Jean Paul’s poor little schoolmaster Wutz gradually acquired by writing, himself, all the works whose titles interested him in book fair catalogues; after all, he could not afford to buy them. Writers are really people who write books not because they are poor, but because they are dissatisfied with the books which they could buy but do not like. You, ladies and gentlemen, may regard this as a whimsical definition of a writer. But everything said from the angle of a real collector is whimsical. Of the customary modes of acquisition, the one most appropriate to a collector would be the borrowing of a book with its attendant non-returning. The book borrower of real stature whom we envisage here proves himself to be an inveterate collector of books not so much by the fervor with which he guards his borrowed treasures and by the deaf ear which he turns to all reminders from the everyday world of legality as by his failure to read these books. If my experience may serve as evidence, a man is more likely to return a borrowed book upon occasion than to read it. And the non-reading of books, you will object, should be characteristic of collectors? This is news to me, you may say. It is not news at all. Experts will bear me out when I say that it is the oldest thing in the world. Suffice it to quote the answer which Anatole France gave to a philistine who admired his library and then finished with the standard question, “And you have read all these books, Monsieur France?” “Not one-tenth of them. I don’t suppose you use your Sèvres china every day?”

In praise of the antilibrary

from Nassim Nicholas Taleb, The Black Swan: The Impact of the Highly Improbable (2007):

The writer Umberto Eco belongs to that small class of scholars who are encyclopedic, insightful, and nondull. He is the owner of a large personal library (containing thirty thousand books), and separates visitors into two categories: those who react with “Wow! Signore professore dottore Eco, what a library you have! How many of these books have you read?” and the others—a very small minority—who get the point that 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.


We tend to treat our knowledge as personal property to be protected and defended. It is an ornament that allows us to rise in the pecking order. So this tendency to offend Eco’s library sensibility by focusing on the known is a human bias that extends to our mental operations. People don’t walk around with anti-résumés telling you what they have not studied or experienced (it’s the job of their competitors to do that), but it would be nice if they did. Just as we need to stand library logic on its head, we will work on standing knowledge itself on its head.
