Umberto Eco on books

From Umberto Eco’s “Vegetal and mineral memory: The future of books” (Al-Ahram Weekly: 20—26 November 2003):

Libraries, over the centuries, have been the most important way of keeping our collective wisdom. They were and still are a sort of universal brain where we can retrieve what we have forgotten and what we still do not know. If you will allow me to use such a metaphor, a library is the best possible imitation, by human beings, of a divine mind, where the whole universe is viewed and understood at the same time. A person able to store in his or her mind the information provided by a great library would emulate in some way the mind of God. In other words, we have invented libraries because we know that we do not have divine powers, but we try to do our best to imitate them. …

First of all, we know that books are not ways of making somebody else think in our place; on the contrary, they are machines that provoke further thoughts. Only after the invention of writing was it possible to write such a masterpiece of spontaneous memory as Proust’s A la Recherche du Temps Perdu. Secondly, if once upon a time people needed to train their memories in order to remember things, after the invention of writing they had also to train their memories in order to remember books. Books challenge and improve memory; they do not narcotise it. …

YET IT IS EXACTLY AT THIS POINT that our unravelling activity must start because by hypertextual structure we usually mean two very different phenomena. First, there is the textual hypertext. In a traditional book one must read from left to right (or right to left, or up to down, according to different cultures) in a linear way. One can obviously skip through the pages, one—once arrived at page 300—can go back to check or re- read something at page 10—but this implies physical labour. In contrast to this, a hypertextual text is a multidimensional network or a maze in which every point or node can be potentially connected with any other node. Second, there is the systemic hypertext. The WWW is the Great Mother of All Hypertexts, a world-wide library where you can, or you will in short time, pick up all the books you wish. The Web is the general system of all existing hypertexts. …

Simply, books have proved to be the most suitable instrument for transmitting information. There are two sorts of book: those to be read and those to be consulted. As far as books-to-be-read are concerned, the normal way of reading them is the one that I would call the ‘detective story way’. You start from page one, where the author tells you that a crime has been committed, you follow every path of the detection process until the end, and finally you discover that the guilty one was the butler. End of the book and end of your reading experience. …

Then they are books to be consulted, like handbooks and encyclopaedias. Encyclopaedias are conceived in order to be consulted and never read from the first to the last page. …

Hypertexts will certainly render encyclopaedias and handbooks obsolete. Yesterday, it was possible to have a whole encyclopaedia on a CD-ROM; today, it is possible to have it on line with the advantage that this permits cross references and the non-linear retrieval of information. …

Books belong to those kinds of instruments that, once invented, have not been further improved because they are already alright, such as the hammer, the knife, spoon or scissors. …

TWO NEW INVENTIONS, however, are on the verge of being industrially exploited. One is printing on demand: after scanning the catalogues of many libraries or publishing houses a reader can select the book he needs, and the operator will push a button, and the machine will print and bind a single copy using the font the reader likes. … Simply put: every book will be tailored according to the desires of the buyer, as happened with old manuscripts.

The second invention is the e-book where by inserting a micro- cassette in the book’s spine or by connecting it to the internet one can have a book printed out in front of us. Even in this case, however, we shall still have a book, though as different from our current ones as ours are different from old manuscripts on parchment, and as the first Shakespeare folio of 1623 is different from the last Penguin edition. Yet, up to now e-books have not proved to be commercially successful as their inventors hoped. … E-books will probably prove to be useful for consulting information, as happens with dictionaries or special documents. …

Indeed, there are a lot of new technological devices that have not made previous ones obsolete. Cars run faster than bicycles, but they have not rendered bicycles obsolete, and no new technological improvements can make a bicycle better than it was before. The idea that a new technology abolishes a previous one is frequently too simplistic. Though after the invention of photography painters did not feel obliged to serve any longer as craftsmen reproducing reality, this did not mean that Daguerre’s invention only encouraged abstract painting. There is a whole tradition in modern painting that could not have existed without photographic models: think, for instance, of hyper-realism. Here, reality is seen by the painter’s eye through the photographic eye. This means that in the history of culture it has never been the case that something has simply killed something else. Rather, a new invention has always profoundly changed an older one. …

The computer creates new modes of production and diffusion of printed documents. …

Today there are new hypertextual poetics according to which even a book-to-read, even a poem, can be transformed to hypertext. At this point we are shifting to question two, since the problem is no longer, or not only, a physical one, but rather one that concerns the very nature of creative activity, of the reading process, and in order to unravel this skein of questions we have first of all to decide what we mean by a hypertextual link. …

In order to understand how texts of this genre can work we should decide whether the textual universe we are discussing is limited and finite, limited but virtually infinite, infinite but limited, or unlimited and infinite.

First of all, we should make a distinction between systems and texts. A system, for instance a linguistic system, is the whole of the possibilities displayed by a given natural language. A finite set of grammatical rules allows the speaker to produce an infinite number of sentences, and every linguistic item can be interpreted in terms of other linguistic or other semiotic items—a word by a definition, an event by an example, an animal or a flower by an image, and so on and so forth. …

Grammars, dictionaries and encyclopaedias are systems: by using them you can produce all the texts you like. But a text itself is not a linguistic or an encyclopaedic system. A given text reduces the infinite or indefinite possibilities of a system to make up a closed universe. If I utter the sentence, ‘This morning I had for breakfast…’, for example, the dictionary allows me to list many possible items, provided they are all organic. But if I definitely produce my text and utter, ‘This morning I had for breakfast bread and butter’, then I have excluded cheese, caviar, pastrami and apples. A text castrates the infinite possibilities of a system. …

Take a fairy tale, like Little Red Riding Hood. The text starts from a given set of characters and situations—a little girl, a mother, a grandmother, a wolf, a wood—and through a series of finite steps arrives at a solution. Certainly, you can read the fairy tale as an allegory and attribute different moral meanings to the events and to the actions of the characters, but you cannot transform Little Red Riding Hood into Cinderella. … This seems trivial, but the radical mistake of many deconstructionists was to believe that you can do anything you want with a text. This is blatantly false. …

Now suppose that a finite and limited text is organised hypertextually by many links connecting given words with other words. In a dictionary or an encyclopaedia the word wolf is potentially connected to every other word that makes up part of its possible definition or description (wolf is connected to animal, to mammal to ferocious, to legs, to fur, to eyes, to woods, to the names of the countries in which wolves exist, etc.). In Little Red Riding Hood, the wolf can be connected only with the textual sections in which it shows up or in which it is explicitly evoked. The series of possible links is finite and limited. How can hypertextual strategies be used to ‘open’ up a finite and limited text?

The first possibility is to make the text physically unlimited, in the sense that a story can be enriched by the successive contributions of different authors and in a double sense, let us say either two-dimensionally or three-dimensionally. By this I mean that given, for instance, Little Red Riding Hood, the first author proposes a starting situation (the girl enters the wood) and different contributors can then develop the story one after the other, for example, by having the girl meet not the wolf but Ali Baba, by having both enter an enchanted castle, having a confrontation with a magic crocodile, and so on, so that the story can continue for years. But the text can also be infinite in the sense that at every narrative disjunction, for instance, when the girl enters the wood, many authors can make many different choices. For one author, the girl may meet Pinocchio, for another she may be transformed into a swan, or enter the Pyramids and discover the treasury of the son of Tutankhamen. …

AT THIS POINT one can raise a question about the survival of the very notion of authorship and of the work of art, as an organic whole. And I want simply to inform my audience that this has already happened in the past without disturbing either authorship or organic wholes. The first example is that of the Italian Commedia dell’arte, in which upon a canovaccio, that is, a summary of the basic story, every performance, depending on the mood and fantasy of the actors, was different from every other so that we cannot identify any single work by a single author called Arlecchino servo di due padroni and can only record an uninterrupted series of performances, most of them definitely lost and all certainly different one from another.

Another example would be a jazz jam session. … What I want to say is that we are already accustomed to the idea of the absence of authorship in popular collective art in which every participant adds something, with experiences of jazz-like unending stories. …

A hypertext can give the illusion of opening up even a closed text: a detective story can be structured in such a way that its readers can select their own solution, deciding at the end if the guilty one should be the butler, the bishop, the detective, the narrator, the author or the reader. They can thus build up their own personal story. Such an idea is not a new one. Before the invention of computers, poets and narrators dreamt of a totally open text that readers could infinitely re-compose in different ways. Such was the idea of Le Livre, as extolled by Mallarmé. Raymond Queneau also invented a combinatorial algorithm by virtue of which it was possible to compose, from a finite set of lines, millions of poems. In the early sixties, Max Saporta wrote and published a novel whose pages could be displaced to compose different stories, and Nanni Balestrini gave a computer a disconnected list of verses that the machine combined in different ways to compose different poems. …

All these physically moveable texts give an impression of absolute freedom on the part of the reader, but this is only an impression, an illusion of freedom. The machinery that allows one to produce an infinite text with a finite number of elements has existed for millennia, and this is the alphabet. Using an alphabet with a limited number of letters one can produce billions of texts, and this is exactly what has been done from Homer to the present days. In contrast, a stimulus-text that provides us not with letters, or words, but with pre-established sequences of words, or of pages, does not set us free to invent anything we want. …

At the last borderline of free textuality there can be a text that starts as a closed one, let us say, Little Red Riding Hood or The Arabian Nights, and that I, the reader, can modify according to my inclinations, thus elaborating a second text, which is no longer the same as the original one, whose author is myself, even though the affirmation of my authorship is a weapon against the concept of definite authorship. …

A BOOK OFFERS US A TEXT which, while being open to multiple interpretations, tells us something that cannot be modified. … Alas, with an already written book, whose fate is determined by repressive, authorial decision, we cannot do this. We are obliged to accept fate and to realise that we are unable to change destiny. A hypertextual and interactive novel allows us to practice freedom and creativity, and I hope that such inventive activity will be implemented in the schools of the future. But the already and definitely written novel War and Peace does not confront us with the unlimited possibilities of our imagination, but with the severe laws governing life and death. …

Eavesdropping with your cell phone

From David S. Bennahum’s “Hope You Like Jamming, Too” (Slate):

…innovative industrial spies, who have several neat new tricks. These days, a boardroom Mata Hari can purchase a specially designed cell phone that will answer incoming calls while appearing to be switched off. In a business meeting, she could casually leave her phone on the table while excusing herself to go to the bathroom. Once she’s gone, she can call the phone she left behind and eavesdrop on what the other side is saying in her absence.

How an email account without passwords can be good for security

From Robert X. Cringely’s “Stream On“:

Mailinator is ad hoc e-mail for those times when just maybe you don’t want to use your regular e-mail address. Say you are snitching on the boss, buying inflatable people, or want 32 different PayPal accounts. Just tell someone—anyone—that your e-mail address is fatman@mailinator.com or skinnykid@mailinator.com, or clueless@mailinator.com or any other address you like at mailinator.com. But this is no dead-end. When people write to you at that address the message will go through. That’s because Mailinator accepts any message going to that domain and automatically assigns an e-mail account to it. But what about passwords? There are none. Anyone can go to Mailinator and check the mail for clueless or any other name. But with so many names and the idea that Mailinator is only for occasional use, who cares?

Better security = reduced efficiency

From Robert X. Cringely’s “Stream On“:

Yet nearly everything we do to combat crime or enhance safety comes at the expense of reduced efficiency. So we build airports to make possible efficient air transportation, then set up metal detectors to slow down the flow of passengers. We build highways to make car travel faster, then set speed limits to make it slower.

The email dead drop

From the L.A. Times‘ “Cyberspace Gives Al Qaeda Refuge“:

Simplicity seems to work best. One common method of communicating over the Internet is essentially an e-mail version of the classic dead drop.

Members of a cell are all given the same prearranged username and password for an e-mail account on an Internet service provider, or ISP, such as Hotmail or Yahoo, according to the recent joint report by the Treasury and Justice departments.

One member writes a message, but instead of sending it, he puts it in the ‘draft’ file and then logs off. Someone else can then sign onto the account using the same username and password, read the draft and then delete it.

‘Because the draft was never sent, the ISP does not retain a copy of it and there is no record of it traversing the Internet—it never went anywhere, its recipients came to it,’ the report said.

American Express’ security policies made things more insecure

From Bruce Schneier’s Crypto-Gram of 15 August 2003:

When I called to activate an American Express credit card I had received in the mail, the automated system told me that I would have to associate a PIN with it. The system told me that other users liked the idea of using their mother’s birthday as a four digit PIN. After some experimentation, I discovered that the system would accept only those four digit PINs that corresponded to dates: 0229 was acceptable but not 0230 and certainly not 3112 (New Year’s Eve, European style.) Thus the system policy administrators had reduced the 10,000 possible four-digit PINs to 366.

Getting past security on planes

From Bruce Schneier’s Crypto-Gram of 15 August 2003:

It’s actually easy to fly on someone else’s ticket. Here’s how: First, have an upstanding citizen buy an e-ticket. (This also works if you steal someone’s identity or credit card.) Second, on the morning of the flight print the boarding pass at home. (Most airlines now offer this convenient feature.) Third, change the name on the e-ticket boarding pass you print out at home to your own. (You can do this with any half-way decent graphics software package.) Fourth, go to the airport, go through security, and get on the airplane.

You can even make a knife on board the plane. Buy some steel epoxy glue at a local hardware store. It comes in two tubes: a base with steel dust and a hardener. Make a knifelike mold by folding a piece of cardboard in half. Then mix equal parts from each tube and form into a knife shape, using a metal fork from your first-class dinner service (or a metal spoon you carry aboard) for the handle. Fifteen minutes later you’ve got a reasonably sharp, very pointy, black steel knife.

Laundering a car’s VIN

From Bruce Schneier’s Crypto-Gram of 15 October 2003:

Precision stripping: criminal steals car, chop shop strips car completely down to chassis, chassis dumped on street, cops tow chassis away, chassis sold at auction, criminal buys chassis, chop shop reattaches parts. Result: legitimate car that can be legally sold used. The VIN has been ‘laundered’.

What seems obvious in security often is not

From Russell Nelson’s comment to Bruce Schneier’s Crypto-Gram of 15 November 2003:

> A New York detective was once asked whether pickpockets in
> Manhattan dressed in suits and ties to facilitate their crimes
> subsequent escape. He responded by saying that in twenty years
> he had never arrested even one pickpocket in a tie.

Do you mean this as evidence to bolster your point or to counter it? It seems to me that if he never arrested even one pickpocket in a tie, that would be very good evidence that pickpockets wearing ties escape arrest.

A nanny’s man-in-the-middle attack

From Bruce Schneier’s Crypto-Gram of 15 April 2004:

Here’s a story of a woman who posts an ad requesting a nanny. When a potential nanny responds, she asks for references for a background check. Then she places another ad, using the reference material as a fake identity. She gets a job with the good references—they’re real, although for another person—and then robs the family who hires her. And then she repeats the process.

Look what’s going on here. She inserts herself in the middle of a communication between the real nanny and the real employer, pretending to be one to the other. The nanny sends her references to someone she assumes to be a potential employer, not realizing that it is a criminal. The employer receives the references and checks them, not realizing that they don’t actually belong to the person who is sending them.

Problems with ID cards

From Bruce Schneier’s Crypto-Gram of 15 April 2004:

My argument may not be obvious, but it’s not hard to follow, either. It centers around the notion that security must be evaluated not based on how it works, but on how it fails.

It doesn’t really matter how well an ID card works when used by the hundreds of millions of honest people that would carry it. What matters is how the system might fail when used by someone intent on subverting that system: how it fails naturally, how it can be made to fail, and how failures might be exploited.

The first problem is the card itself. No matter how unforgeable we make it, it will be forged. And even worse, people will get legitimate cards in fraudulent names. …

Not that there would ever be such thing as a single ID card. Currently about 20 percent of all identity documents are lost per year. An entirely separate security system would have to be developed for people who lost their card, a system that itself is capable of abuse. …

But the main problem with any ID system is that it requires the existence of a database. In this case it would have to be an immense database of private and sensitive information on every American—one widely and instantaneously accessible from airline check-in stations, police cars, schools, and so on.

The security risks are enormous. Such a database would be a kludge of existing databases; databases that are incompatible, full of erroneous data, and unreliable. …

What good would it have been to know the names of Timothy McVeigh, the Unabomber, or the DC snipers before they were arrested? Palestinian suicide bombers generally have no history of terrorism. The goal is here is to know someone’s intentions, and their identity has very little to do with that.

Security decisions are often made for non-security reasons

From Bruce Schneier’s Crypto-Gram of 15 July 2004:

There was a single guard watching the X-ray machine’s monitor, and a line of people putting their bags onto the machine. The people themselves weren’t searched at all. Even worse, no guard was watching the people. So when I walked with everyone else in line and just didn’t put my bag onto the machine, no one noticed.

It was all good fun, and I very much enjoyed describing this to FinCorp’s VP of Corporate Security. He explained to me that he got a $5 million rate reduction from his insurance company by installing that X-ray machine and having some dogs sniff around the building a couple of times a week.

I thought the building’s security was a waste of money. It was actually a source of corporate profit.

The point of this story is one that I’ve made in ‘Beyond Fear’ and many other places: security decisions are often made for non-security reasons.

The real digital divide: knowing how to use what you have & not knowing

From Howard Rheingold’s interview in “Howard Rheingold’s Latest Connection” (Business Week: 11 August 2004):

Here’s where Wikipedia fits in. It used to be if you were a kid in a village in India or a village in northern Canada in the winter, maybe you could get to a place where they have a few books once in a while. Now, if you have a telephone, you can get a free encyclopedia. You have access to the world’s knowledge. Knowing how to use that is a barrier. The divide increasingly is not so much between those who have and those who don’t, but those who know how to use what they have and those who don’t.

How free riders are good for open source

From Howard Rheingold’s interview in “Howard Rheingold’s Latest Connection” (Business Week: 11 August 2004):

Then there’s open source [software]. Steve Weber, a political economist at UC Berkeley, sees open source as an economic means of production that turns the free-rider problem to its advantage. All the people who use the resource but don’t contribute to it just build up a larger user base. And if a very tiny percentage of them do anything at all—like report a bug—then those free riders suddenly become an asset.
