Aesthetic Dualities

From the existence of the popular, memetic expressions listed in the sections below it’s evident that languages are aesthetic and made up of alternating references to various simple, more and less exciting dualistic opposites. Dualities considered here, with the more exciting quality written first, include: hot — cold, fluid — solid, dynamic — static, disorder — order, bright — dark, up — down, out — in, many — few, high-pitch — low-pitch, spiky — round and long — round.

The given exciting qualities are related in a category in the subconscious mind and the less exciting opposite qualities are related in an opposite mental category. Heat subconsciously reminds us of dynamism, disorder, brightness, upwardness, outwardness and other exciting things such as anger and sex. Meanwhile, coldness is reminiscent of stasis, order, darkness, downwardness, inwardness and other lower-excitement qualities.

As a result of these and other universal subconscious associations we recognize a set of dualities not observably present in the outside world. One can choose any member of the more exciting quality category, mix it perceptually with any quality from the opposite, less exciting category and derive the structure of numerous aesthetic phenomena including a large portion of the idiomatic (literally nonsensical) expressions we use in everyday language.

Perceptual mixtures of qualities across mental categories convey a degree of mystery, surprise and aesthetic value compared to perceptual combinations of qualities from within one or the other mental category. Something perceptually hot, fluid, dynamic, disorderly, bright and so on is exciting to animals compared to something cold, solid, static, orderly and dark, while mixtures of these qualities such as bright solidness and dark fluidity are moderately exciting, interesting, relatively likable and amusing.

Even though the diametric opposite of heat in nature is coldness, darkness is also its opposite in the mind. The reverse is true as well, by default, so that brightness is opposite to both darkness and coldness in the brian but only to darkness in nature. While this can be determined using idioms, or poetry, it’s also evident from experiments with brightness and temperature as variables (Bellia et al. 2019):

“The Hue Heat Hypothesis (HHH) is based on the idea that light and colours of the environment can affect thermal perception and influence thermal comfort. Specifically, it states that, when spectral power distribution of light reaching an observer’s eye is characterized by long wavelengths in the visible spectrum, the space is perceived as warmer; conversely, when small wavelengths are predominant, the space is perceived as cooler.”

“Thermal comfort” is one way to describe the psychology of the hue heat effect, but it can also be put in terms of preferences. A person in a hotter environment is more comfortable in or prefers to be in a darker (smaller wavelength), black- or blue-colored room, for instance, and a person who feels colder prefers to be in a room with “hotter-colored” (longer wavelength) white, red or yellow walls. In other words, the mixtures hot — dark and bright — cold are preferred over or more likable than the congruent psychophysical combinations hot — bright and cold — dark.

In accordance with the hue-heat effect hotter animals, those living near the equator, for example, should be expected to prefer and court with darker mates. Oppositely, animals living in colder places or near the poles should prefer brighter mates, leading to very general dark to bright gradients in animal body color from hotter to colder locations. This is observable in birds, bears, wild cats, zebras, aquatic mammals and others, meaning the hue-heat effect operates independently of species and taxonomic variation in brains, and that a psychophysical aesthetic mechanism is largely responsible rather than differential survival as usually employed to understand biological traits and trends.

Deriving Aesthetic Structures

Because heat corresponds to greater fluidity in matter, including especially that of extremely liquid crystalline objects like brains, one can replace heat in the hue-heat preference/effect with fluidity, replace coldness with solidness and derive the aesthetic structures fluid — dark and bright — solid, which also correspond to universal preferences and effects. One can go on substituting qualities correlated with changes in brain temperature and fluidity to derive quality pairs corresponding to other aesthetic preferences, such as the following, in which fluidity is replaced by physically correlated dynamism, disorder and upwardness and solidness is replaced with stasis, order and downwardness:

dynamic — dark/bright — static,

disorder — dark/bright — order,

up— dark/bright — down.

Substituting qualities correlated with brain temperature for their psychologically categorical relatives generates further commonly preferred aesthetic structures. By this process one ultimately arrives at a set of amusing mixtures like the following, all of which have numerous matching idiomatic expressions:

hot — cold*, hot — solid, hot — order, hot — dark, hot — static, hot — down, hot — in, fluid — cold, fluid — solid*, fluid — order, fluid — dark, fluid — static, fluid — down, fluid — in, disorder — cold, disorder — solid, disorder — order*, disorder — dark, disorder — static, disorder — down, disorder — in, bright — cold, bright — solid, bright — order, bright — dark*, bright — static, bright — down, bright — in, dynamic — cold, dynamic — solid, dynamic — order, dynamic — dark, dynamic — static*, dynamic — down, dynamic — in, up — cold, up — solid, up — order, up — dark, up — static, up — down*, up — in, out — cold, out — solid, out — order, out — dark, out — static, out — down, out — in*.

Diametrically opposite mixtures or those we can observe to be opposed to each other outside the brain are marked with an asterisk. These might tend to be slightly more common in aesthetic material than the listed non-diametrically opposed dualities, but it’s clear from the lists below that we’re amused by all of these mixtures, indicating liquid crystallinity in the brain is fundamental to our sense of beauty. The stories Dynamic Darkness and Bright Stasis in Animals and Painted by Nature demonstrate the usefulness of thinking of animal coloration as a result of preferences for mixtures of dynamism and upwardness with darkness and stasis and downwardness with brightness.

Mixture Lists

Aesthetic mixtures occur much more frequently in poetry than prose because poetry is relatively aesthetic and more reflective of the brain and mind than normal, practical language. Mixtures (or dualities or aesthetic structures) are written in bold throughout the following lists, and those that are underlined are linked to lists of poems written by authors on Medium demonstrating the aesthetic use of the given mixture. All other languages must have similar idioms, given their frequency in English.

It’s arguable whether the qualities upward, downward, outward and inward relate to physical changes in the brain but I’ve included them here because they occur as commonly in idiomatic language as more obviously physics-related phenomena, and because there’s a strong argument that they are physical, given the upward and outward nature of hot matter relative to cold matter. Brightness is included because it’s obvious that a brain experiencing light and brightness is more excited and hotter than a brain experiencing darkness. All of the lists are under construction.

Roundness, Length and Spikiness in Language

The story Disruptions of Roundness discusses an evidently universal human desire to disturb perceptually round objects in a variety of ways for amusement. Roundness is often mixed with heat, fluidity, disorder, brightness, motion, upwardness and outwardness, as well as high-pitch, multiplicity, and the opposites of roundness length and spikiness. It’s clear for various reasons that animals find high-pitched sounds and large numbers of things (multiplicity or many) more exciting than their opposite's low-pitch and low numbers (singularity or few), so these are included as aesthetic opposites of roundness.

Hot — round (7: a hot spot, like a hot potato, a full head of steam, hotter than a hooker’s doorknob on nickel night, hot as balls, great balls of fire, a snowball’s chance in hell); fluid — round (11: here’s spit in your eye, a spot of tea, fountainhead, grease the wheels, when life gives you lemons make lemonade, the African proverb rain beats the leopard’s skin but it does not wash out the spots, the whole ball of wax, honeymoon, the squeaky wheel gets the grease, slimeball, scuzball, just spitballing,); dynamic — round (15: get the ball rolling, running around in circles, get the runaround, run of the mill, turning point, turn a blind eye, head spinning, heads will roll, get a head start, around the clock, it’s a coin toss, turn on a dime, a leopard cannot change its spots, that’s the way the ball bounces, play ball, in broad strokes); disorder — round (18: a broken record, vicious circle, breaking point, flipped it on its head, turn the world upside down, bad apple, quit busting my balls, upset the apple cart, fucking around, mess around, a spot of bother, a spot of trouble, throw you a curveball, kick the tires, you can’t make an omelet without breaking a few eggs, the wheels fell off, don’t get your balls in a twist, it’s all fun and games until somebody loses an eye, break a butterfly upon a wheel); bright — round (9: in the twinkle of an eye, sparkle in your eye, starry-eyed, bright-eyed and bushy-tailed, a red cent, lightning round, moon beam, moonshine, flashpoint); up — round (7: eye in the sky, pie in the sky, all balled up, jumping through hoops, keep your chin up, keep your head up, heads up); out — round (8: trippin balls, balls out, point out, eye-popping, keep an eye out, a head trip, off with her head, heading out, knock the spots off, burst your bubble); high-pitch — round (1: the squeaky wheel gets the greese); many — round (11: all around, all around town, an eye for an eye, all eyes on, go head to head, have a lot on the ball, comparing apples and oranges, many moons, a dime a dozen, don’t put all your eggs in one basket, a third wheel); long — round (5: the longest way round is the shortest way home, can’t make heads or tails of it, the short end of the stick, headline, dickhead); spiky — round (8: keep a sharp eye out, screwball, the hairy eyeball, square the circle, X marks the spot, a sharp cookie, poking around, better than a poke in the eye with a sharp stick).

Long — cold (1: it’ll be a long day in January); long — solid (4: long in the tooth, by a long chalk, he who sups with the devil should have a long spoon, long and strong); long — static (2: hold the line, the king is dead long live the king); long — order (1: the long arm of the law); long — dark (5: cast a long shadow, all night long, night of the long knives, old sins have long shadows); long — down (5: down the line, lay it on the line, a long row to hoe, the bottom line, long walk on a short pier); long — in (5: strap in, pull some strings, pulling your leg, a long time coming, a needle in a haystack); long — singular (2: the last straw, the straw that breaks the camel’s back); long — short (4: the long and short of it, to make a long story short, take a long walk on a short pier, bright-eyed and bushy-tailed).

Spiky — solid (4: a bull in a china shop, bullshit, cut the tension with a knife, sharp as a steel trap); spiky — static (3: lock horns, seize the bull by the horns, he who lives by the sword dies by the sword); spiky — dark (1: night of the long knives); spiky — down (3: catch a falling knife, fall on your sword, dipstick); spiky — in (2: pull in horns, not the sharpest knife in the drawer); spiky — short (1: short sharp shock).

Longer Aesthetic Sequences and Degrees of Excitement

Overall levels of excitement can be calculated and compared for popular expressions containing sequences of more than two references to thermoaesthetic qualities. Excitement degrees, based on the sum of distinct references in a phrase to more (plus one) and less (minus one) exciting qualities should give some idea of how agreeable we find an expression. Zero degrees of excitement, which characterizes all the expressions above, should be most agreeable and deviations from zero in either direction should tend to be less so.

So far the expression “all hell breaks loose” deviates from a zero excitement level the most, with the aesthetic structure multiple — hot — disorder — out and degrees calculated as 1+1+1+1=4. “Rain hellfire down upon” is second, with the structure fluid/down — hot/bright/fluid — down — up and 1–1+1+1+1–1+1=3 degrees of excitement. Some words/concepts refer to more than one quality at a time. These are written separated by forward slashes. For instance, since rain and tears are both fluid and downward they have the aesthetic structure fluid/down and 1–1=0 aesthetic excitement degrees.

Heat (2): Burning the midnight oil (hot/bright — dark — fluid), burning the midnight oil (hot — dark — fuid=1); fluidity (4): rain hellfire down upon (fluid/down — hot/bright/fluid — down — up=3), blood runs cold (fluid — dynamic — cold=1), sow the wind and reap the whirlwind (down — fluid — disorder — up=-1+1+1+1=2), pour your heart out (fluid /down— in — out=0); dynamism (6): live fast die young (dynamic — dynamic — static=1), go down swinging (dynamic — down — dynamic=1), living under a rock (dynamic — down — solid=-1), stir up shit (dynamic — up — solid=1), turn that frown upside down (dynamic — up — down=1), go down a storm (dynamic — down — fluid=1), going down the tubes (dynamic — down — in=-1); disorder (2): come crumbling down (in — disorder — down=-1), strike when the iron is hot (disorder — solid — heat=1), break a leg (disorder — long/solid/down=0); brightness (1): day in and day out (bright — in — bright — out=0); upwardness (3): jump right in (up — order — in=-1), what goes up must come down (dynamic — up — down=1), a rising tide lifts all boats (up — fluid — up — solid/container=1); outwardness (1): thrown under the bus (dynamic — down — solid/in=-2), don’t give up your day job (out — up — bright=3); multiplicity (1): all hell breaks loose (multiple — hot — disorder — out=4); stasis (2): still waters run deep (static — fluid — dynamic — down=0), a bed of roses (static/down — bright/fluid/multiple=1), “stop, drop and roll” (static — down — dynamic=-1); solidness (1): land you in hot water (in — hot — fluid=1), bury the hatchet (solid/spiky — down/in=0), iron out the wrinkles (solid/order — out — disorder=0); darkness (1): a dark cloud hanging over (dark — fluid — down — up=0); downardness (1): hanging over your head (down — up — round=-1), dragged kicking and screaming (down/dynamic — dynamic — high-pitch=2); inwardness (4): suck the life out of (in — dynamic — out=1), take the long way home (in — long — in), it’s eating me up inside (in — up — in=-1), in cold blood (in — cold — fluid/bright=0); roundness (1): apple of my eye (bright/round — round=-1); few (1): once in a blue moon (singular — dark — round/solid=-4).
