Amazon Best Books of the Month, December 2012: Fragile things break under stress. But, according to Nassim Nicholas Taleb, there's an entire class of other things that don't simply resist stress but actually grow, strengthen, or otherwise gain from unforeseen and otherwise unwelcome stimuli. Taleb sees degrees of antifragility everywhere, from fasting, mythology, and urban planning to economic, technological, cultural, and biological systems. The wealth of radical thinking in this book astounds; the glossary alone offered more thought-provoking ideas than any other nonfiction book I read this year. That said, Antifragile is far from flawless. As comical as Taleb's rough handling of his favorite targets can be--academics, economists, and tourists, to name a few--his argumentative style boasts gaping holes, non sequiturs aplenty, and at times an almost willfully repugnant tone. Some readers will find Taleb's brashness off-putting; others will embrace it as a charismatic component of the ideas themselves. Either way, no one will finish this book unchanged. --Jason Kirk --This text refers to an alternate kindle_edition edition.

Half of Life Has No Name

You are in the post office about to send a gift, a package full of champagne glasses, to a cousin in Central Siberia. As the package can be damaged during transportation, you would stamp “fragile,” “breakable,” or “handle with care” on it (in red). Now what is the exact opposite of such situation, the exact opposite of “fragile”?

Almost all people answer that the opposite of “fragile” is “robust,” “resilient,” “solid,” or something of the sort. But the resilient, robust (and company) are items that neither break nor improve, so you would not need to write anything on them—­have you ever seen a package with “robust” in thick green letters stamped on it? Logically, the exact opposite of a “fragile” parcel would be a package on which one has written “please mishandle” or “please handle carelessly.” Its contents would not just be unbreakable, but would benefit from shocks and a wide array of trauma. The fragile is the package that would be at best unharmed, the robust would be at best and at worst unharmed. And the opposite of fragile is therefore what is at worst unharmed.

We gave the appellation “antifragile” to such a package; a neologism was necessary as there is no simple, noncompound word in the Oxford English Dictionary that expresses the point of reverse fragility. For the idea of antifragility is not part of our consciousness—­but, luckily, it is part of our ancestral behavior, our biological apparatus, and a ubiquitous property of every system that has survived.

To see how alien the concept is to our minds, repeat the experiment and ask around at the next gathering, picnic, or pre-­riot congregation what’s the antonym of fragile (and specify insistently that you mean the exact reverse, something that has opposite properties and payoff). The likely answers will be, aside from robust: unbreakable, solid, well-­built, resilient, strong, something-­proof (say, waterproof, windproof, rustproof)—­ unless they’ve heard of this book. Wrong—­and it is not just individuals but branches of knowledge that are confused by it; this is a mistake made in every dictionary of synonyms and antonyms I’ve found.

Another way to view it: since the opposite of positive is negative, not neutral, the opposite of positive fragility should be negative fragility (hence my appellation “antifragility”), not neutral, which would just convey robustness, strength, and unbreakability. Indeed, when one writes things down mathematically, antifragility is fragility with a negative sign in front of it.

This blind spot seems universal. There is no word for “antifragility” in the main known languages, modern, ancient, colloquial, or slang. Even Russian (Soviet version) and Standard Brooklyn English don’t seem to have a designation for antifragility, conflating it with robustness.

Half of life—­the interesting half of life—­we don’t have a name for.

Please Behead Me

If we have no common name for antifragility, we can find a mythological equivalence, the expression of historical intelligence through potent metaphors. In a Roman recycled version of a Greek myth, the Sicilian tyrant Dionysius II has the fawning courtier Damocles enjoy the luxury of a fancy banquet, but with a sword hanging over his head, tied to the ceiling with a single hair from a horse’s tail. A horse’s hair is the kind of thing that eventually breaks under pressure, followed by a scene of blood, high-­pitched screams, and the equivalent of ancient ambulances. Damocles is fragile—­it is only a matter of time before the sword strikes him down.

In another ancient legend, this time the Greek recycling of an ancient Semitic and Egyptian legend, we find Phoenix, the bird with splendid colors. Whenever it is destroyed, it is reborn from it own ashes. It always returns to its initial state. Phoenix happens to be the ancient symbol of Beirut, the city where I grew up. According to legend, Berytus (Beirut’s historical name) has been destroyed seven times in its close to five-­thousand-­year history, and has come back seven times. The story seems cogent, as I myself saw the eighth episode; central Beirut (the ancient part of the city) was completely destroyed for the eighth time during my late childhood, thanks to the brutal civil war. I also saw its eighth rebuilding.

But Beirut was, in its latest version, rebuilt in even better shape than the previous incarnation—­and with an interesting irony: the earthquake of a.d. 551 had buried the Roman law school, which was discovered, like a bonus from history, during the reconstruction (with archeologists and real estate developers trading public insults). That’s not Phoenix, but something else beyond the robust. Which brings us to the third mythological metaphor: Hydra.

Hydra, in Greek mythology, is a serpent-­like creature that dwells in the lake of Lerna, near Argos, and has numerous heads. Each time one is cut off, two grow back. So harm is what it likes. Hydra represents antifragility.

The sword of Damocles represents the side effect of power and success: you cannot rise and rule without facing this continuous danger—­ someone out there will be actively working to topple you. And like the sword, the danger will be silent, inexorable, and discontinuous. It will fall abruptly after long periods of quiet, perhaps at the very moment one has gotten used to it and forgotten about its existence. Black Swans will be out there to get you as you now have much more to lose, a cost of success (and growth), perhaps an unavoidable penalty of excessive success. At the end, what matters is the strength of the string—­not the wealth and power of the dining party. But, luckily, this is an identifiable, measurable, and tractable vulnerability, for those who want to listen. The entire point of the Triad is that in many situations we can measure the strength of the string.

Further, consider how toxic such growth-­followed-­by-­a-­fall can be to society, as the fall of the dining guest, in response to the fall of the sword of Damocles, will bring what we now call collateral damage, harming others. For instance, the collapse of a large institution will have effects on society.

Sophistication, a certain brand of sophistication, also brings fragility to Black Swans: as societies gain in complexity, with more and more “cutting edge” sophistication in them, and more and more specialization, they become increasingly vulnerable to collapse. This idea has been brilliantly—­and convincingly—­adumbrated by the archeologist Joseph Tainter. But it does not have to be so: it is so only for those unwilling to go the extra step and understand the matrix of reality. To counter success, you need a high offsetting dose of robustness, even high doses of antifragility. You want to be Phoenix, or possibly Hydra. Otherwise the sword of Damocles will get you.

On the Necessity of Naming

We know more than we think we do, a lot more than we can articulate. If our formal systems of thought denigrate the natural, and in fact we don’t have a name for antifragility, and fight the concept whenever we use our brains, it does not mean that our actions neglect it. Our perceptions and intuitions, as expressed in deeds, can be superior to what we know and tabulate, discuss in words, and teach in a classroom. We will have ample discussions of the point particularly with the potent notion of the apophatic (what cannot be explicitly said, or directly described, in our current vocabulary); so for now, take this curious phenomenon.

In Through the Language Glass, the linguist Guy Deutscher reports that many primitive populations, without being color-­blind, have verbal designations for only two or three colors. But when given a simple test, they can successfully match strings to their corresponding colors. They are capable of detecting the differences between the various nuances of the rainbow, but they do not express these in their vocabularies. These populations are culturally, though not biologically, color-­blind.

Just as we are intellectually, not organically, antifragility-­blind. To see the difference just consider that you need the name “blue” for the construction of a narrative, but not when you engage in action.

It is not well known that many colors we take for granted had no name for a long time, and had no names in the central texts in Western culture. Ancient Mediterranean texts, both Greek and Semitic, also had a reduced vocabulary of a small number of colors polarized around the dark and the light—­Homer and his contemporaries were limited to about three or four main colors: black, white, and some indeterminate part of the rainbow, often subsumed as red, or yellow.

I contacted Guy Deutscher. He was extremely generous with his help and pointed out to me that the ancients even lacked words for something as elementary as blue. This absence of the word “blue” in ancient Greek explains the recurring reference by Homer to the “wine-­dark sea” (oinopa ponton), which has been quite puzzling to readers (including this one). --This text refers to an alternate kindle_edition edition.

Judging by his anecdotes, Taleb interacts with the economic masters of the universe as he jets from New York to London or attends business-politics confabs in Davos, Switzerland. Anything but awed by them, Taleb regards them as charlatans, not as credible experts. Such skepticism toward elites, which imbued Taleb’s The Black Swan: The Impact of the Highly Improbable (2007), continues in this work, which grapples with a concept Taleb coins as “antifragile.” Not readily reducible to a definition (Taleb takes the whole book to develop the idea), suffice to say here that antifragile’s opposites—economic, political, or medical systems that are vulnerable to sudden collapse—tend to be managed by highly educated people who think they know how systems work. But they don’t, avers Taleb. Their confidence in control is illusory; their actions harm rather than help. In contrast, Taleb views decentralized systems—the entrepreneurial business rather than the bureaucratized corporation, the local rather than the central government—as more adaptable to systemic stresses. Emphatic in his style and convictions, Taleb grabs readers given to musing how the world works. --Gilbert Taylor --This text refers to an alternate kindle_edition edition.
