“No one ever explained the octopuses”*…

We humans are forward-facing, gravity-bound plodders. David Borkenhagen wonders if the liquid motion of the octopus can radicalize our ideas about time…

… The octopus may navigate its ocean home with ease, but it can seem like a creature from another planet. It populates our popular visions of cosmic beings and extraterrestrial life, with its eight arms, three hearts, and a malleable body without bones. What’s more, its ability to camouflage itself, coupled with a propensity to hide in tight holes, make it a master of disguise. If seen, a water siphon that expels inhaled water can instantly propel the creature away from danger in any direction in three-dimensional aquatic space. Its web of radially symmetrical arms allow it to crawl in any direction with equal competence, regardless of how its head is oriented. Its soft and malleable body can move through any crevasse larger than its beak. And with its two eyes positioned on opposite sides of its head, it has a near-total field of vision with almost nothing hidden ‘behind’. These abilities give the octopus a radically different relationship to its surroundings compared with other species, human or otherwise. It is a relationship free of constraints.

And what about our bodies? Compared with the octopus, human beings appear corporeally constrained. We lack the fluid mobility and wide field of vision of our (very, very) distant cephalopod cousins. Instead, we have two eyes stuck in the front of our heads. We have a paltry two legs, hardwired for forward movement. And we are bound to our terrestrial ecological niche, where our bodies must continually counteract the downward pull of gravity.

It’s not only that our experiences of space are different. Our experiences of time are likely different, too. We think about the passage of time through our terrestrial experience of unidirectional motion through space – our metaphors of time are almost all grounded in the way our bodies move forward through the environment. Given this fact, how would an octopus, who can easily see and move in all directions, conceptualise time? Current research methods may be able to take us only part of the way toward an answer, but it’s far enough to consider a radical possibility: if we became more like an octopus, could we free time, metaphorically speaking, from its constraints? Could we experience it as multidimensional, fluid and free?…

[Borkenhagen reviews the research on octopuses and what it tells us about how their relationships with time and death]

… In many ways, the octopus represents a challenge, or a profound limit, to our conventional ways of thinking about time and death. But it’s more than a challenge. It’s also an invitation. With its unconstrained movements and semelparous lifecycle, the octopus offers a radically different perspective on the fluidity and flexibility of existence. Could we learn to move through time as an octopus moves through space? With equal access to the past, present and future – viewed wide or with sharp focus – we might better navigate the challenges of living and dying on Earth. The octopus invites us to think in a way that dissolves the boundaries between the present and the future, understanding our ‘ending’ less as a fixed point and more as a fluid process stretching across generations. As the boundary between life and death dissolves and becomes more porous, so do the boundaries between ourselves and others. The metaphors we used to inhabit our time here may seem impoverished, but there’s another way. It’s in the unconstrained movements of an octopus traveling through space – fluid, flexible and free…

As we re-understand unfolding, we might recall that it was on this date in 1871 that the American Museum of Natural History opened to the public in New York City. Organized into a series of exhibits, the Museum’s collection–which had been gathered from the time of the Museum’s founding in 1869– went on view for the first time in the Central Park Arsenal, the Museum’s original home, on the eastern side of Central Park. The cornerstone of the Museum’s first building was laid in Manhattan Square (79th Street and Central Park West), the Museum’s current location, in 1874; but it is obscured from view by the many Museum buildings in the complex that today occupy most of the Square.

“The brain is a wonderful organ; it starts working the moment you get up in the morning and does not stop until you get into the office”*…

For as long as humans have thought, humans have thought about thinking. George Cave on the power and the limits of the metaphors we’ve used to do that…

For thousands of years, humans have described their understanding of intelligence with engineering metaphors. In the 3rd century BCE, the invention of hydraulics popularized the model of fluid flow (“humours”) in the body. This lasted until the 1500s, supplanted by the invention of automata and the idea of humans as complex machines. From electrical and chemical metaphors in the 1700s to advances in communications a century later, each metaphor reflected the most advanced thinking of that era. Today is no different: we talk of brains that store, process and retrieve memories, mirroring the language of computers.

I’ve always believed metaphors to be helpful and productive in communicating unfamiliar concepts. But this fascinating history of cognitive science metaphors shows that flawed metaphors can take hold and limit the scope for alternative ideas. In the worst case, the EU spent 10 years and $1.3 billion building a model of the brain based on the incorrect belief that the brain functions like a computer…

As we cogitate on cognition, we might send carefully-computed birthday greetings to Grace Brewster Murray Hopper.  A seminal computer scientist and Rear Admiral in the U.S. Navy, “Amazing Grace” (as she was known to many in her field) was one of the first programmers of the Harvard Mark I computer (in 1944), invented the first compiler for a computer programming language, and was one of the leaders in popularizing the concept of machine-independent programming languages– which led to the development of COBOL, one of the first high-level programming languages.

Hopper also (inadvertently) contributed one of the most ubiquitous metaphors in computer science: she found and documented the first computer “bug” (in 1947).

She has both a ship (the guided-missile destroyer USS Hopper) and a super-computer (the Cray XE6 “Hopper” at NERSC) named in her honor.

“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.
