“There’s no idea in economics more beautiful than Arrow’s impossibility theorem”*…

Tim Harford unpack’s Kenneth Arrow‘s Impossibility Theorem (which feels a bit like a socio-economic “Monty Hall Problem“) and considers it’s implications…

… if any group of voters gets to decide one thing, that group gets to decide everything, and we prove that any group of decisive voters can be pared down until there’s only one person in it. That person is the dictator. Our perfect constitution is in tatters.

That’s Arrow’s impossibility theorem. But what does it really tell us? One lesson is to abandon the search for a perfect voting system. Another is to question his requirements for a good constitution, and to look for alternatives. For example, we could have a system that allows people to register the strength of their feeling. What about the person who has a mild preference for profiteroles over ice cream but who loathes cheese? In Arrow’s constitution there’s no room for strong or weak desires, only for a ranking of outcomes. Maybe that’s the problem.

Arrow’s impossibility theorem is usually described as being about the flaws in voting systems. But there’s a deeper lesson under its surface. Voting systems are supposed to reveal what societies really want. But can a society really want anything coherent at all? Arrow’s theorem drives a stake through the heart of the very idea. People might have coherent preferences, but societies cannot…

On choice, law, and the paradox at the heart of voting: “Arrow’s Impossibility Theorem,” from @TimHarford in @WhyInteresting. Eminently worth reading in full.

As we contemplate collective choice, we might send grateful birthday greetings to the man who “wrote the book” on perspective, Leon Battista Alberti; he was born on this date in 1404.  The archetypical Renaissance humanist polymath, Alberti was an author, artist, architect, poet, priest, linguist, philosopher, cartographer, and cryptographer.  He collaborated with Toscanelli on the maps used by Columbus on his first voyage, and he published the the first book on cryptography that contained a frequency table.

But he is surely best remembered as the author of the first general treatise– Della Pictura (1434)– on the the laws of perspective, which built on and extended Brunelleschi’s work to describe the approach and technique that established the science of projective geometry… and fueled the progress of painting, sculpture, and architecture from the Greek- and Arabic-influenced formalism of the High Middle Ages to the more naturalistic (and Latinate) styles of Renaissance.

“In every grain of sand there is the story of the earth”*…

(Roughly) Daily has looked before (see here and here) at sand as a critical ingredient in the stuff of modern life. Today’s post features Steven Connor on the metaphorical power of sand…

Sand belongs to the great, diffuse class, undeclared, rarely described, but insistent and insinuating, of what may be called quasi-choate matters — among them mist, smoke, dust, snow, sugar, cinders, sleet, soap, syrup, mud, toffee, grit. Such pseudo-substances hover, drift, and ooze between consistency and dissolution, holding together even as they come apart from themselves. And, of all of these dishesive matters, sand is surely the most untrustworthy, the most shifting and shifty.

Nobody would seriously consider taking a stand on a cloud, but sand has betrayed many an architect and edifice. Sand is at once architectural and archiclastic. An eighteenth-century continuation of Baron Munchausen’s adventures describes how the Baron and his party survive a whirlwind of sand by scooping an igloo-style sand-chamber in which to shelter from the storm, and then digging a tunnel from their bunker back out into the light. Sand has the capacity to engulf and inundate, blearing contours, eroding and erasing every edge and eminence. As such it is the ultimate mockery of the permanence of stone, for it is no more than one of stone’s own moods, the manner in which stone, atomised, consumes itself. Shelley’s “Ozymandias” imagines the monumental statue of Rameses the Great dismembered on the Egyptian sands. The shattered chunks of head, legs, and pedestal portend a further, finer comminution, after the membra disjecta themselves will have been milled away into flatness: “Round the decay/Of that colossal wreck, boundless and bare,/The lone and level sands stretch far away.”

Sand is reversible. Only utter desiccation can attain to this pouring, milk-smooth liquefaction. Sand-baths were used in the ancient world both to draw out the damp ague of rheumatism and as a kind of sauna, to promote perspiration. Sand is the product of abrasion, but is also itself abrasive, used in sand-blasting to etch and burnish. Pliny tells us of the use of sand under a saw edge to make a clean cut in marble, and to polish it after it has been carved.

Sand signifies neutrality, indifference, and uniformity; yet it also has hairtrigger sensitivity and responsiveness. A grain of sand (in actual fact often a tiny parasite) is the irritant that provokes in the oyster the nacreous secretions that build into a pearl. Sand has a favoured relation to sound, putting a hoarse rattle in the throat of the wind, and is itself all ears. In 1787, the German physicist Ernst Chladni showed how drawing a violin bow over a metal plate could induce in the fine sand sprinkled on it hierophantic figurings of the sound, in quivering mandalas and ripple-fingered arpeggios. Though sand can disfigure and obliterate, it can also disclose the ghost wrist of wind and the perturbations of the earth. It is a detection and reception mechanism, forming ridged isobars, shivering musculature, oscilloscape of the air’s sculpting shoves and gusts.

Sand participates in dream and vision. The Sandman brings sleep by throwing or blowing sand into the eyes of children. But the sand does more than merely seal the eyes, for in many versions of this nursery tale, it is the very stuff that dreams are made on, the numb matter of sleep, swirling, particulate, that the sandman carries in his sack. The somnolence of sand is redoubled when in Top Hat (1935) Fred Astaire soothes Ginger Rogers to sleep in the hotel room below him by spreading sand on the floor and hush-dancing a susurrous soft-shoe shuffle. The origins of moon-walking are to be found in the novelty slides and scrapes across a sanded stage by music-hall acts like Wilson, Keppel and Betty. Specious it may be, but sand is also the secret stuff of omen and auspice, in the practice of divination through tossing and scrying handfuls of sand, known in Arabic as ilm al-raml, the science of the sand, or what might have been its Greek equivalent, psammomancy.

Sand is not only temporary, it is also the most temporised form of matter. It is the image or allegory of time, shifting, yet unshiftable. It seems a compiling of the minced, mounded years that go into its making, and grains of sand imitate the elementary atoms of time, moment upon pattering moment. Sand is featureless, without joints or divisions, even though it is nothing but division all the way down. Yet it is this very feature that makes it useful in the measurement of time, for, unlike other materials, sand will flow easily and regularly, even as its volume diminishes. Sand-glasses came into use in part because of the need to measure time at sea, far from any landmark; speed would be measured by counting the number of knots in a rope paid out from the back of the ship in the time it took for the sand to run through a half-minute glass. A half-hour period of watch, known as a “glass”, was also measured in this way. Grains of sand, in the form of quartz crystals, with their precise oscillations, still micro-regulate our time. In fact, the sand of hourglasses was often not quartz sand at all, but powdered marble, or eggshell. But we find it hard to give up the idea of the affinity of sand and the glass through which it runs, since silicates of sand are still the most important source of glass. George Herbert imagines this interfusion when he writes that “flesh is but the glasse, which holds the dust/That measures all our time; which also shall/Be crumbled into dust”, while for Gerard Manley Hopkins the soul itself is “soft sift/In an hourglass – at the wall/Fast, but mined with a motion, a drift,/And it crowds and it combs to the fall”…

From the mythical Sandman, through the grains in an hourglass, to an irritating mote lodged in the beachgoer’s eye, sand harbors unappreciated power: “The Dust That Measures All Our Time.”

As we muse on metaphor, we might send ideal birthday greetings to Marsilio Ficino; he was born on this date in 1433.  An Italian scholar and Catholic priest, he was one of the most influential humanist philosophers of the early Italian Renaissance.  The first translator of Plato’s complete extant works into Latin, he was important in the revival of Neoplatonism, and was in touch with every major academic thinker and writer of his day. His Florentine Academy was an attempt to revive Plato’s Academy, and influenced both the direction and the tenor of the Italian Renaissance and thus the development of European philosophy.

Ficino was also an astrologer, and is credited with having inspired the Tarot card deck– the Tarot of Marseilles– that was the pattern from which many subsequent tarot decks derive.

“Do not explain your philosophy. Embody it.”*…

Truth, knowledge, justice – to understand how our loftiest abstractions earn their keep, trace them to their practical origins…

Unlike ideas of air, food and water that allow us to think about the everyday resources we need to survive, the venerable notions of knowledge, truth or justice don’t obviously cater to practical needs. On the contrary, these exalted ideals draw our gaze away from practical pursuits. They are imbued with grandeur precisely because of their superb indifference to mundane human concerns. Having knowledge is practically useful, but why would we also need the concept of knowledge? The dog who knows where his food is seems fine without the concept of knowledge, so long as he’s not called upon to give a commencement address. And yet the concepts of knowledge, truth or justice appear to have been important enough to emerge across different cultures and endure over the ages. Why, then, did we ever come to think in these terms?

Friedrich Nietzsche grumbled that, when it came to identifying the origins of lofty ideas, philosophers had a tendency to be led astray by their own respect for them. In dealing with what they felt were the ‘highest concepts’, the ‘last wisps of smoke from the evaporating end of reality’, they had reverently placed them ‘at the beginning as the beginning’, convinced that the higher could never have grown out of the lower: Plato’s eternal Forms, the mind of God, Immanuel Kant’s noumenal world – they had all served as cradles to higher concepts, offering them a suitably distinguished pedigree.

But to insist that higher concepts were bound to have higher origins, Nietzsche thought, was to let one’s respect for those ideas get in the way of a truthful understanding of them. If, after the ‘Death of God’ and the advent of Darwinism, we were successfully to ‘translate humanity back into nature’, as Nietzsche’s felicitous rallying cry had it, we needed to trace seemingly transcendent ideas such as knowledge, truth or justice to their roots in human concerns. Their origins weren’t empyrean (to be sought in the highest spheres) but distinctly sublunary (found in lowly practical needs). Nietzsche encouraged us to ask: what necessities might have been the mothers of those inventions? And what, if anything, do they still do for us?…

As we root out first principles, we might spare a thought for Sir Alfred Jules “Freddie” Ayer (usually cited as A.J. Ayer); he died on this date in 1989. A philosopher associated with the the British humanist movement, he is best remembered as the champion of of logical positivism, particularly in his books Language, Truth, and Logic (1936) and The Problem of Knowledge (1956). While he had a number of material disagreements with Nietzsche, Ayer shared his rejection of objective ethical values.

“Custom is the great guide to human life”*…

Which graph to use for which type of data

The r/coolguides page on Reddit has lots of fun and useful stuff to browse through from guides on wilderness survival to vintage instructions about talking on the telephone. I hope I never actually need to refer to the one about “how to make seawater drinkable”, but I do think it’s a good skill to know, just in case I find myself stuck in a rubber boat with Tallulah Bankhead and William Bendix. I have similar feelings about the “Circles of Hell in Dante’s Inferno” guide, but it’s probably wise to have it on hand, just in case I need it as a map one day…

As we find our way, we might recall that it was on this date in 1523 that the Parisian Faculty of Theology fined Simon de Colines for publishing the Biblical commentary Commentarii initiatorii in quatuor Evangelia by Jacques Lefèvre d’Étaples, a “guide” to the four Gospels. Lefèvre d’Étaples, a theologian and a leading figure in French humanism, whose work anticipated the Protestant Reformation, was frequently ruled heretical– though he remained within the church throughout his life.

The Wild One

Marlon Brando, The Wild One

 

Throughout the 1930s, the sleepy town of Hollister [California], not far from Monterey Bay, had made a pastime of hosting motorcycle rallies. Paused during World War II, an Independence Day rally returned in 1947 with a pent-up energy like never before.

By the end of the holiday weekend, roughly 50 bikers had been arrested for public drunkenness and other forms of debauchery. Then they left, and life in Hollister went back to normal. But the lore of what became dubbed the Hollister Riot grew. Breathless news accounts told of “havoc” and “pandemonium” on the streets of small-town America.

A couple weeks later LIFE magazine published a S.F. Chronicle photo from Hollister, pictured above, showing a drunken fellow teetering atop a Harley, a beer bottle in each fist and a pile of spent bottles at his feet. The headline: “Cyclists’ Holiday: He and friends terrorize a town.”

Historians have questioned whether this photo from the so-called Hollister Riot was staged. Barney Peterson/S.F. Chronicle

LIFE was read by roughly 10% of the country at a time before widespread adoption of the television. The image of wild men on motorcycles, Hunter S. Thompson observed, was like nothing America had ever seen.

In “Hell’s Angels: A Strange and Terrible Saga,” Thompson wrote: “There was absolutely no precedent, in the years after World War II, for large gangs of hoodlums on motorcycles, reveling in violence, worshiping mobility and thinking nothing of riding five hundreds miles on a weekend … to whoop it up with other gangs of cyclists in some country hamlet entirely unprepared to handle even a dozen peaceful tourists.”

A few years after Hollister, Harper’s Magazine published a fictionalized version of the rally that was in turn crafted into a Hollywood depiction. “The Wild One” premiered in 1953 starring heartthrob Marlon Brando as the iconic biker outlaw Johnny Strabler.

At one point in the movie, a little girl asks Strabler what he’s rebelling against.

“Whaddya got?” he replies.

Over the years, mainstream motorcycle groups sought to dispel their reputation as hell-raising ruffians. But other clubs wore it proudly. They called themselves one-percenters, a response to the claim that 99% of motorcyclists are model citizens. The most notorious, the Hell’s Angels, was founded in Fontana not long after Hollister. Their motto: “When we do right, nobody remembers. When we do wrong, nobody forgets.”…

As we hit the road, we might spare a thought for Desiderius Erasmus Roterodamus, better known simply as Erasmus; he died on this date in 1536.  A Catholic priest, social critic, teacher, translator, and theologian, probably best remembered for his book In Praise of Folly, he was the greatest scholar of the northern Renaissance, the first editor of the New Testament (“Do unto others…”), and an important figure in patristics and classical literature.  Among fellow scholars and philosophers he was– and is– known as the “Prince of the Humanists.”
