Not only does Ullman tell us what it was like to be an engineer during the dot-com bubble, but she does it in prose that many professional writers envy.

Places that have never existed except in the human imagination may find an incongruous afterlife in the everyday world. Umberto Eco tells of how an attempt to commemorate the brownstone New York home of Nero Wolfe, Rex Stout’s orchid-loving fictional detective, runs up against the resistance of fact. Wolfe’s house cannot be identified because Stout “always talked of a brownstone at a certain number on West 35th Street, but in the course of his novels he mentioned at least ten different street numbers – and what is more, there are no brownstones on 35th Street”. Using Eco’s typology, a fiction has been transmuted into a legend: “Legendary lands and places are of various kinds and have only one characteristic in common: whether they depend on ancient legends whose origins are lost in the mists of time or whether they are in effect a modern invention, they have created flows of belief.”

Because they involve the belief that they existed, exist or can be made to exist – whether in the past, the future or somewhere off the map – legendary places are illusions rather than fictions. The distinction may sometimes be blurry, as the example of Nero Wolfe’s house shows; but the difference is fundamental to this enriching and playfully erudite exploration of the fabulous lands that human beings have invented.

Fictions we know to be neither true nor false and paradoxically this gives them a kind of absolute veracity that historical facts can never have: “The credulous believe that El Dorado and Lemuria exist or existed somewhere or other, but we all know that it is undeniably certain that Superman is Clark Kent and that Dr Watson was never Nero Wolfe’s right-hand man ... All the rest is open to debate.” Unfortunately, humans have an invincible need to believe in their fictions. So they turn them into legends, which they anxiously defend from doubt – even to the point of attacking and killing those who do not share them.

Eco thinks it is not too difficult to explain why humankind is so drawn to legendary places: “It seems that every culture – because the world of everyday reality is cruel and hard to live in – dreams of a happy land to which men once belonged, and may one day return.” Nowadays everyone believes that the ability to envision alternate worlds is one of humankind’s most precious gifts, a view Eco seems to endorse when, at the end of his journey through legendary lands, he describes these visions as “a truthful part of the reality of our imagination”. Yet Eco highlights a darker side of these visions when he describes how the Nazis drew inspiration from legends of ancient peoples, variously situated in ultima Thule (“a land of fire and ice where the sun never set”), Atlantis and the polar regions, who spoke languages that were “racially pure”. Himmler was obsessed with ancient Nordic runes, while in an interview after the war the commander of the SS in Rome claimed that when Hitler ordered him to kidnap Pope Pius XII so he could be interned in Germany, he also ordered the Pope to take from the Vatican library “certain runic manuscripts that evidently had esoteric value for him”.

The Nazi adoption of the swastika began with the Thule Society, a secret racist organisation founded in 1918. Legends of lost lands fed the ideology of Aryan supremacy. In 1907, Jörg Lanz founded the Order of the New Temple, preaching that “inferior races” should be subjected to castration, sterilisation, deportation to Madagascar and incineration – ideas, Eco notes, that “were later to be applied by the Nazis”. Legendary lands are idylls from which minorities, outsiders and other disturbing elements have been banished. When these fantasies of harmony enter politics, a process of exclusion is set in motion whose end point is mass murder and genocide.

A metamorphosis of fiction into legend occurred when some Nazis took seriously a picture of the world presented by the Victorian novelist Edward Bulwer-Lytton. In his novel The Coming Race (1871), Bulwer-Lytton tells of the “Vril-ya”, survivors from the destruction of Atlantis who possessed amazing powers as a result of being imbued with Vril, a type of cosmic energy, living in the hollow interior of earth. He intended the book as an exercise in fantasy literature but the founder of the Thule Society, who also founded a Vril Society, seems to have taken it more literally. Occultists in several countries read Bulwer-Lytton’s novel as a fictional rendition of events that may actually have happened and the legend was mixed in the stew of mad and bad ideas we now call Nazism.

The process at work was something like that described in Jorge Luis Borges’s story “Tlön, Uqbar, Orbis Tertius”, in which an encyclopaedia of an imaginary world subverts and disrupts the world that has hitherto been real. The difference is that in Borges’s incomparable fable the secret society that devised the encyclopaedia knew it to be fiction, while 19th-century occultists and some 20th-century Nazis accepted Bulwer-Lytton’s fiction as a version of fact. Among the marks that Bulwer-Lytton’s Vril-ya left in the real world, the most lasting was reassuringly prosaic: the name given to Bovril, the meat extract invented in the 1870s.

Among the legendary places human beings have dreamed up, those that Eco calls “the islands of utopia” have exercised a particular fascination in recent times. As he reminds us, “Etymologically speaking, utopia means non-place” – ou-topos, or no place. Thomas More, who coined the term in his book Utopia (composed in Latin and only translated in 1551 after More had been executed for treason in 1535), plays on an ambiguity in which the word also means a good or excellent place. Using a non-existent country to present an ideal model of government, More established a new literary genre, which included Étienne Cabet’s A Journey to Icaria (1840), in which a proto-communist society is envisioned, Samuel Butler’s Erewhon (1872, an anagram of “nowhere”) and William Morris’s News from Nowhere (1890).

Visions of ideal societies have recurred throughout history but such societies were nearly always placed in an irretrievable past. The paradise of milk and honey of which human beings dreamed – a land of perpetual peace and abundance – belonged in religion and mythology rather than history or science. Yet by the end of the 19th century, the fiction of an ideal society had been turned into a realisable human condition. Already in the second half of the 18th century, Rousseau was writing of an egalitarian society as if something of the kind had once existed – a move repeated by Marx and Engels in their theory of primitive communism, which they believed could be recreated at a higher level. More’s non-existent land was given a veneer of science and situated in a non-existent future. Having been a literary genre, utopia became a political legend.

The Book of Legendary Lands covers a vast range of non-places, including a flat and a hollow earth, the Antipodes, the lands of Homer and the many versions of Cockaigne (where honey and bread fall from the sky and no one is rich or poor). A fascinating chapter deals with the far more recent invention of Rennes-le-Château, a French village near Carcassonne that has been hailed as a site of immense treasure and of a priory established by descendants of Jesus, who supposedly did not die on the cross but fled to France and began the Merovingian dynasty.

Presented by Eco in light and witty prose, these legendary places are made more vivid by many well-chosen illustrations and historic texts. Yet this is far from being another coffee table book, however beautiful. As in much of his work, Eco’s theme is the slippage from fiction to illusion in the human mind. Rightly he sees this as a perennial tendency but it is one that has gathered momentum in modern times. So-called primitive cultures understood that history runs in cycles, with civilisations rising and falling much as the seasons come and go – a view of things echoed in Aristotle and the Roman historians. The rise of monotheism changed the picture, so that history came to be seen as an unfolding drama – a story with a beginning, an end and a redemptive meaning. Either way, no one believed that history could be governed by human will. It was fate, God or mere chaos that ruled human events.

Legendary lands began to multiply when human beings started to believe they could shape the future. Non-places envisioned by writers in the past were turned into utopian projects. At the same time, literature became increasingly filled with visions of hellish lands. As Eco puts it, “Sometimes utopia has taken the form of dystopia, accounts of negative societies.”

What counts as a dystopia, however, is partly a matter of taste. Aldous Huxley may have meant Brave New World (1932) as a warning but I suspect many people would find the kind of world he describes – genetically engineered and drug-medicated but also without violence, poverty or acute unhappiness – quite an attractive prospect. If the nightmarish society Huxley imagines is fortunately impossible, it is because it is supposed to be capable of renewing itself endlessly – a feature of utopias and one of the clearest signs of their unreality.

Whether you think a vision of the future is utopian or not depends on how you view society at the present time. Given the ghastly record of utopian politics in the 20th century, bien-pensants of all stripes never tire of declaring that all they want is improvement. They assume that the advances of the past are now permanent and new ones can simply be added on. But if you think society today is like all others have been – deeply flawed and highly fragile – you will understand that improvement can’t be inherited in this way. Sooner or later, past advances are sure to be lost, as the societies that have inherited them decline and fail. As everyone understood until just a few hundred years ago, this is the normal course of history.

No bien-pensant will admit this to be so. Indeed, many find the very idea of such a reversal difficult to comprehend. How could the advances that have produced the current level of civilisation – including themselves – be only a passing moment in the history of the species? Without realising the fact, these believers in improvement inhabit a legendary land – a place where what has been achieved in the past can be handed on into an indefinite future. The human impulse to dream up imaginary places and then believe them to be real, which Eco explores in this enchanting book, is as strong as it has ever been.

Peter Suchin reappraises the prismatic works of Roland Barthes – an author who defied his own pronouncement of the designation’s demise. From the Marxist of Mythologies to the ‘scientist’ of S/Z, Suchin discovers a writer who understood the pleasure of text

Roland Barthes par Roland Barthes, Seuil, 1975In her obituary of Roland Barthes Susan Sontag observed that Barthes never underlined passages in the books he read, instead transcribing noteworthy sections of text onto index cards for later consultation. In recounting this practice Sontag connected Barthes’ aversion to this sacrilegious act of annotation with ‘the fact that he drew, and that this drawing, which he pursued seriously, was a kind of writing.’[1] Sontag was making reference to the 700 or so drawings and paintings left by Barthes – usually regarded as a literary critic and social commentator – at his death as the result of a road accident in 1980.

Occasionally reproduced in his books, most visibly on the cover of Roland Barthes par Roland Barthes (1975), but never exhibited during his lifetime, these paintings were, as Barthes himself pointed out, the work of an amateur. ‘The Amateur’, he noted, ‘engages in painting, music, sport, science, without the spirit of mastery or competition[...] he establishes himself graciously (for nothing) in the signifier: in the immediately definitive substance of music, of painting[...] he is – he will be perhaps – the counter-bourgeois artist.’[2]

If Barthes was happy to be an amateur he nonetheless gave this word the weight of a serious critical designation. The practice of an amateur is ‘counter-bourgeois’ insofar as it manages to escape commodification, having been made for the pleasure implicit in production itself, rather than for monetary gain or cultural status. Barthes’ paintings relay an indulgence in the materiality of the brush or pen as it moved across the support, in the body’s engagement with the texture of paint, the physical trace of a shimmering track of ink or a riotous collision of colours. ‘I have an almost obsessive relation to writing instruments’, he reflected in 1973. ‘I often switch from one pen to the other just for the pleasure of it. I try out new ones. I have far too many pens – I don’t know what to do with all of them.’[3] For Barthes, who wrote all his texts by hand, this concern with the tools of writing was connected with his experience and recognition of the intimate materiality of artistic production. Each day he found time to sit at the piano, ‘fingering’ as he called it, and had taken singing lessons in his youth and acted in classical Greek theatre whilst a student at the Sorbonne in the 1930s. The ‘corporeal, sensual content of rock music...expresses a new relation to the body’, he told an interviewer in 1972: ‘it should be defended.’[4]

Barthes’ perceptive analyses of French culture, collected together in Mythologies (1957), were, like his other early writings, overtly Marxist. This approach was later superseded by one in which his prose mimicked the ostensible neutrality of scientific discourse. S/Z (1970), for example, mapped five cultural codes onto a Balzac short story which had been divided up by Barthes into 561 fragments or ‘lexias’, the text being taken to pieces as though it were being examined in a laboratory. His tour de force semiological study of The Fashion System (1967) had relied on a similarly ‘objective’ approach to the linguistic niceties of fashion writing. But the practice of the later Barthes – the Barthes of The Pleasure of the Text (1973), A Lover’s Discourse (1977), and Camera Lucida (1980) – revealed the earlier publications to be complicated machines for the generation of diverse forms of language, modes of writing, as opposed to ‘matter of fact’ commentaries or critiques. When considered together as a corpus or oeuvre, Barthes numerous books suggest an emphatically idiosyncratic individual and author whose ‘political’ and ’scientific’ writings were but elements in a constantly shifting trajectory, stages in a literary career whose central motivation was the repeated reinvigoration of language. Like that of Proust, whose work he described as being for him ‘the reference work...the mandala of the entire literary cosmogony’[5], Barthes’ life might be said to be inseparable from this practice of writing. ‘The language I speak within myself is not of my time’, he mused in The Pleasure of the Text; ‘it is prey, by nature, to ideological suspicion; thus, it is with this language I must struggle. I write because I do not want the words I find...’ (p. 40). This act of writing was not so much a reflection of the ‘self’ Barthes happened to be at a given moment as a means of self-invention, of, in fact, reinvention without end. To work on language was, for Barthes, to work upon the self, engaging with received ideas, cultural stereotypes, and cliches of every kind in order to overthrow or reposition them, moving around and through language into another order of action and effect. ‘All his writings are polemical,’ suggests Sontag, but a strong optimistic strand is clearly evident too: ‘He had little feeling for the tragic. He was always finding the advantage of a disadvantage.’[6]

But if one was, as a human being, condemned to relentlessly signify, to make, and be oneself made into ‘meanings’, Barthes seriously pursued in his watercolours and assiduous scribbles the impossible position of the exemption of meaning. If these paintings are ‘a kind of writing’, they are forgeries, fragments of false tongues and imaginary ciphers, closer to what Barthes himself termed ‘texts of bliss’, rather than ‘texts of pleasure’, though positioned somewhere between the two.

This opposition, which runs through The Pleasure of the Text, defines texts of pleasure as constituting an attractive but ultimately mundane aesthetic form, whilst those of bliss or, in the French, jouissance, comprise a radical break, not merely within language but within the very fabric of culture itself. Such a binary opposition can be found elsewhere in Barthes’ writings. The terms ‘studium’ and ‘punctum’ in Camera Lucida are a case in point, the former referring to the commonality of photographic representations with which we are today surrounded, whilst ‘punctum’ designates a puncture or disturbance in the viewer. ‘A detail overwhelms the entirety of my reading; it is an immense mutation of my interest...By the mark of something, the photograph is no longer “anything whatever”.’ (p. 49) With such an emphasis on the reader’s or viewer’s individual response Barthes moved closer and closer to autobiography and the subjective format of the jotting or journal. Most famous for his 1968 essay ‘The Death of the Author’, the acutely particular tone of Barthes’ writing later appears to contradict the loss of authorial authority celebrated in this immensely influential work.[7] Rather than ‘critic’, ‘literary historian’ or ‘structuralist’, the appelation ‘writer’ looks to be the most succinct for all the different ‘Barthes’ we encounter in his writings. He is finally all these things and none, ‘a subject in process’, to use a term from his student Julia Kristeva.[8] Yet Barthes recognised that the artist or author can never control meaning, that the last word always belongs to someone else: ‘to write is to permit others to conclude one’s own discourse, and writing is only a proposition whose answer one never knows. One writes in order to be loved, one is read without being able to be loved, it is doubtless this distance which constitutes the writer.’[9]

Over the past several days, a certain Star Trek: The Next Generation prose piece has ensnared the popular imagination the world over. It's a story that's been recycled since time immemorial, due to its sheer cross-cultural thematic resonance.

I am, of course, referring to author Kitty Glitter's Amazon Kindle tour de force Wesley Crusher: Teenage Fuck Machine, an edifying fable in which the Enterprise's resident rascal has a sexual awakening during a threesome with a barbed-penised cat man. Also, Captain Jean Luc Picard is walloped in the gonads.

There’s a new online threat to writing. Critics of the web like to blame email, texts, and chat for killing prose. Even blogs—present company included—don’t escape their wrath. But in fact the opposite is true: thanks to computers, writing is thriving. More people are writing more than ever, and this new wave of everyone’s-an-author bodes well for the future of writing, even if not all that makes its way online is interesting or high in quality.

But two new digital developments, ebook spam and content farms, now threaten the survival of writing as we know it.

For a long time, it was the folks who downloaded music or movies illegally that faced the wrath of government prosecutors. So the unsealing of an indictment today against Aaron Swartz, former Reddit-er and founder of Demand Progress, for the illegal download of some 4 million-odd academic journal articles may sound a bit unusual. Demand Progress has issued a statement suggesting Swartz's actions were akin to "checking too many books out of the library." But the government clearly disagrees as the charges include wire fraud, computer fraud, and unlawfully obtaining information from a protected computer. Schwartz now faces up to 35 years in prison and up to $1 million in fines.

Two summers ago, the Atlantic published an essay by Nicholas Carr, one of the blogosphere's most prominent (and thoughtful) contrarians, under the headline "Is Google Making Us Stupid?".

"Over the past few years," Carr wrote, "I've had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory.

The UK government is said to have set in motion a law change that will prevent the Pope from being arrested when he visits the country in September. Officials in Whitehall – the UK government’s administrative offices – are said to be worried over plans by the atheist authors Richard Dawkins and Christopher Hitchens to have Pope Benedict arrested for crimes against humanity, because of his alleged cover-up of priestly assaults on children. “Mr Dawkins, the atheist campaigner, and Mr Hitchens, an atheist author, asked human rights lawyers in April to put together a case for charging the Pope over his alleged cover-up of sexual abuse of children in the Catholic Church,” reports Pink News today. Its report adds: “Justice Secretary Ken Clarke proposed changes to the law today which would require the consent of the Director of Public Prosecutions to any arrest warrant issued under universal jurisdiction.” The Pope’s proposed visit has ever been free of controversy since it was announced last

About a month ago in handling the remains of one Dr. Fred McCabe I found rich notes of contemplation on the subject of information theory. It appears that Fred could have written an entire book on the intricacies of hidden data, encoded messages and deceptive methods of transmission. Instead his notes exist in the form of a cryptic assemblage of definitions and examples, arranged into what Dr. McCabe himself labelled a series of ‘moments’.

I offer these moments alongside some of the ten thousand images Dr. McCabe amassed in a separate, but intimately linked, archive. The preface to this abridged compendium is little capable of preparing one for the disarray of material, but by introducing this text with Fred's own words it is my hope that a sense of the larger project will take root in the reader’s fertile imagination.

The Moment of the Message: A Diatribe

by Dr. Fred McCabe

More than ten thousand books on mathematics and a thousand books on philosophy exist for every one upon information. This is surprising. It must mean something.

I want to give you a message. But first. I have to decide how to deliver the message.

This is that moment.

I can write it down, or perhaps memorise it – reciting it in my head like a mantra, a prayer chanted in the Palace gardens. And later, speaking in your ear, I will repeat it to you. That is, if you want to hear it.

I could send it to you, by post, or telegram. After writing it down I will transmit it to you. Broadcasting on your frequency in the hope that you will be tuned in at the right moment. Speaking your language. Encoded and encrypted, only you will understand it.

I have a message for you and I want you to receive it. But first. I have to decide what the message is.

This is that moment:

This is the moment of the message

From the earliest days of information theory it has been appreciated that information per se is not a good measure of message value. The value of a message appears to reside not in its information (its absolutely unpredictable parts) but rather in what might be called its redundancy—parts predictable only with difficulty, things the receiver could in principle have figured out without being told, but only at considerable cost in money, time, or computation. In other words, the value of a message is the amount of work plausibly done by its originator, which its receiver is saved from having to repeat.

This is the moment my water arrived at room temperature

The term enthalpy comes from the Classical Greek prefix en-, meaning "to put into", and the verb thalpein, meaning "to heat".

For a simple system, with a constant number of particles, the difference in enthalpy is the maximum amount of thermal energy derivable from a thermodynamic process in which the pressure is held constant.

This is the moment the wafer became the body of Christ

The Roman Catholic Church got itself into a bit of a mess. Positing God as the victim of the sacrifice introduced a threshold of undecidability between the human and the divine. The simultaneous presence of two natures, which also occurs in transubstantiation, when the bread and wine become the body and blood of Christ, threatens to collapse the divine into the human; the sacred into the profane. The question of whether Christ really is man and God, of whether the wafer really is bread and body, falters between metaphysics and human politics. The Pope, for all his failings, has to decide the undecidable.

This is the moment black lost the game

A ko fight is a tactical and strategic phase that can arise in the game of go.

Some kos offer very little gain for either player. Others control the fate of large portions of the board, sometimes even the whole board, and the outcome of those kos can determine the winner of the game. For this reason, finding and using ko threats well is a very important skill.

This is the moment Robinson Crusoe becomes the first, English language novel

According to Abel Chevalley, a novel is: "a fiction in prose of a certain extent”, defining that "extent" at over 50,000 words. Some critics distinguish the novel from the romance (which has fantastic elements), the allegory (in which characters and events have political, religious or other meanings), and the picaresque (which has a loosely connected sequence of episodes). Some critics have argued that Robinson Crusoe contains elements of all three of these other forms.

This is the moment Sarah Conner takes control

A paper clip is usually a thin wire in a looped shape that takes advantage of the elasticity and strength of the materials of its construction to compress and therefore hold together two or more pieces of paper by means of torsion and friction. Some other kinds of paper clip use a two-piece clamping system.

In fiction, a paper clip often takes the place of a key as means of breaking and entering, or, in Sarah Conner’s case, as means of escape.

This is the moment they found the missing piece of DNA

In northern Spain 49,000 years ago, 11 Neanderthals were murdered. Their tooth enamel shows that each of them had gone through several periods of severe starvation, a condition their assailants probably shared. Cut marks on the bones indicate the people were butchered with stone tools. About 700 feet inside the cave, a research team excavated 1,700 bones from that cannibalistic feast. Much of what is known about Neanderthal genetics comes from those 11 individuals.

This is the moment Bill Clinton lied (to himself)

A microexpression is a brief, involuntary facial expression shown on the face according to emotions experienced. They usually occur in high-stake situations, where people have something to lose or gain. Unlike regular facial expressions, it is difficult to fake microexpressions. Microexpressions express the seven universal emotions: disgust, anger, fear, sadness, happiness, surprise, and contempt. They can occur as fast as 1/25 of a second.

This is the moment I strained my iris

Idiopathic is an adjective used primarily in medicine meaning arising spontaneously or from an obscure or unknown cause. From Greek idios (one's own) and pathos (suffering), it means approximately "a disease of its own kind."

This is the moment everything changed

In ordinary conversation, everything usually refers only to the totality of things relevant to the subject matter. When there is no expressed limitation, everything may refer to the universe or the world.

Every object and entity is a part of everything, including all physical bodies and in some cases all abstract objects. Everything is generally defined as the opposite of nothing, although an alternative view considers "nothing" a part of everything.

This is the moment of another message

In information theory the value of a message is calculated by the cost it would take to repeat or replace the work the message has done.

One might argue that a message’s usefulness is a better measure of value than its replacement cost. Usefulness is an anthropocentric concept that information theorists find difficult to conceptualise.

The Táin lithographs In 1967 Louis le Brocquy was commissioned to illustrate Thomas Kinsella's translation of the great Irish prose epic the Táin Bó Cuailnge. The resulting collaborative volume is widely acknowledged as the great Irish Livre d'Artiste of the twentieth century; Le Brocquy's "brush drawings merged seamlessly with the text; stark, fluent images, they expressed with great economy of means an epic breadth, evoking the movement of vast masses of people. Individual participants in the drama were also pulled into close focus."

I can feel it, too. Over the past few years I’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn’t going—so far as I can tell—but it’s changing. I’m not thinking the way I used to think. I can feel it most strongly when I’m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I’d spend hours strolling through long stretches of prose. That’s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle.
