Books

The cover of the latest Time issue contains a photo of Jonathan Franzen accompanied with the following message:

Great American Novelist. He's not the richest or most famous. His characters don't solve mysteries, have magical powers or live in the future. But in his new novel, Freedom, Jonathan Franzen shows us the way we live now.


The fact that the person placed on the Time's cover is a living novel writer was so surprising, that a number of other media sources dedicated a news entry for it. It appeared that Jonathan Franzen is the first writer for 10 years to get to the cover of this magazine (the previous one was Stephen King in 2000).

In my opinion, this fact is not a worse illustration of the way we live now than the mentioned book. For 50 years (1951-2000) as many as 42 living writers were honoured to get to the Time's cover, ~8 authors per decade. The first decade of 2000's was not that rich. However, I cannot say that the shelves of bookstores have become smaller. Conversely, they obviously have become much larger than ten years ago. And the books have become much more colourful and pretty than before (right now I'm looking at my good old Catcher in the Rye, 1975 edition, and I'm sure it would have never been sold in today's bookstore due to its ugly cover).

The abundance on the bookshelves hides the scarcity of modern literature. It is the same entropy loss problem I wrote about some time ago. The problem is that we produce a lot of form, while forgetting about the sense. A typical book available in a store today is nothing more than a coloured pack of printed paper whose life is limited by a trip from New York to San Francisco. What a difference to my Catcher, the Catcher I've bought at bibliopole's, whose pages become yellow with time, who has some wrested pages pasted back in wrong order, who spent his best years being read by a dozen of my friends (and their friends), and who is still alive and carefully dusted once a week on a dedicated bookcase shelf, waiting for succeeding readers.

Entropy loss problem

Past decades are widely considered as the period of enormous growth of the amount of information available around the world. Though the overall amount of information on the planet has really grown significantly (and continues to grow), a much bigger basis for this viewpoint, as for me, lies in dramatic decrease of entropy in the information data surrounding us.

I cannot say “the entropy in the information surrounding us” as this is not formally correct, because “information” assumes 100% entropy, while abstract “data” may contain no information at all (and thus have zero entropy).

What we have today is enormous growth of the amount of data, not information. We have more books, more music bands, more radio stations, more TV channels. However, all those sources bring us much less information than they used to 50 years ago. Most of the news channels use original copy-and-paste method, obtaining news from a small number of information agencies (e.g. Thomson-Reuters or Associated Press), and only several of them do work on producing something more intellectual than just reproducing the facts. The shelves of bookstores are full of books, but it is quite difficult to choose a good book to read. Finally, I have just entirely stuffed my new 400GB hard drive, but I doubt that my PC contains ten times more information than it used to do with 40GB drive ten years ago.

Why entropy loss is a problem? Due to its flooding effect, of course. There is just too much low-entropy data around us, so retrieving high-entropy data requires more and more efforts to be done. Moreover, certain skills are needed to be able to tell a smile from a veil (C); it is too easy to get led by fake ideals. Finally, the world is not that simple by itself, so why should we make it more complicated by bringing extra trash into it?
