Scapulimancy

Scapulimancy (pronounced skap-yuh-luh-man-see)

Divination of the future by observation of the cracking of a mammal's scapula (the shoulder blade, the bone connecting the clavicle to the humerus), sometimes after having been heated by fire or a hot instrument.

1870–1875: The construct was scapul(a) + -i- + -mancy.  Scapula was from the Late Latin scapula (shoulder), from the Classical Latin scapulae (shoulders).  The -mancy suffix was from the Latin -mantīa, ultimately from the Ancient Greek μᾰντείᾱ (manteíā) (divination).  In English it was appended to convey the sense either of (1) divination or (2) in fantasy, varieties of magic, especially those controlling or related to specific elements, substances, or themes.  The synonym is omoplatoscopy and the alternative spelling scapulomancy.  Scapulimancy is a noun, scapulimantic is an adjective and scapulimanticly is an adverb.

Divination was from the Latin divinare (to foresee, foretell or predict; tom make prophesy) and is a general term describing attempts to gain insight into a question or situation by way of an occultic ritual or practice, usually involving either (1) some object or objects in which special qualities are said to be vested, (2) an alleged contact or interaction with supernatural entities or agencies such as spirits, gods, god-like-beings or the other forces “of the universe” or (3) the interpretation of signs or omens, variously defined.  As a cultural practice, divination has been identified in many cultures and at the root of it is probably a desire to have explained what is by all other means available, inexplicable.  That obviously offers some potential for exploitation by those seeking social, political or religious authority but it can also be a business model and between that and religion especially, there’s historically been some overlap, something alive and well today.  The notion of using the shoulder blades of slaughtered animals for this purpose may seem strange but as a method it seems no more or less convincing than instruments such as the tea-leaf, rune stones, Tarot-cards or the movement of objects in the heavens, some billions of miles remote from the apparent randomness of events on Earth.

Although much-associated with priests, magicians and prophets (again, the overlap not hand to find), divination was practiced also by those for whom religion (in the way the word is conventionally understood) wasn’t a significant force.  The Hun of the Eurasian steppe, best remembered for their fifth century invasion of the Roman Empire, may have Turkic language (though one much infused with words from others), are known to have never developed writing and never seem to have flirted beyond the vaguest with God or gods, the only devotional aspect of their culture a kind of “nature worship”, something which would probably now attract much sympathy.  There may though have been something of a cargo-cult in that various objects seem to have been associated with a kind of veneration, notably swords or weapons linked with military success and generals down the ages, however practical and pragmatic they might have been in other matters, are recorded by historians or in diaries as being fond of consulting soothsayers the night before a battle.  The Huns definitely practiced scapulimancy, the logs of travelers and merchants recording how a shaman-like figure would take from the fire the shoulder blades of the roasted sheep, “reading the patterns” on the surface to make predictions for the days, the foretold omens revealed by pits, stains ridges & hollows which made each bone as unique as a finger-print.  This use for the sheep’s scapula adds another layer to the oft-repeated observation about the reductive efficiency of the steppe peoples in the husbanding of their scare resources: “For some purpose, they used every part of the sheep”.  Because the Huns left no written records, all that is known of their scapulimantic technique comes from third-party observers but as far as is known, their practice was in the “pyromantic” tradition (the “preparing” of the bone by leaving it for a time in the embers of the cooking fire), the “apyromantic” (examination after the flesh had been cut from the bone) method most known in Europe & Northern Africa.  Both these descriptions came from the work of nineteenth century anthropologists.

It’s not only in the post-Enlightenment West that divination has (mostly) been dismissed as silly superstition, many thinkers from Antiquity pointing out in their writings the absurdity of the idea and their most effective criticism was probably not the abstract arguments philosophers usually can’t resist but a simple “fact-checking”: comparing predictions with outcomes, the success rate found predictably low.  In the text of one sceptic however, there appears to be the first mention of the efficacy, even in the age of climate change, of one reliable prediction about the weather: “three times out of four, the weather tomorrow will be much the same as today.” (YMMV).  However, despite the two-thousand-odd years of intellectual scorn, the lure of prediction by dubious means remains strong, some otherwise respectable publications regularly including a horoscope, even though there’s nothing to suggest astrology is otherwise taken seriously.  It seems star-sighs exert a special fascination and many identify with their birth sign and read the horoscope, even if usually for amusement.  For some though it’s serious.  Nancy Reagan (1921–2016; US First Lady 1981-1989) regularly consulted an astrologer (on the White House payroll for a reputed US$3000 a month) after one warned her husband Ronald Reagan (1911-2004; US president 1981-1989) would be “in danger” on a certain day; on that day he survived an assassination attempt.

Others couldn’t quite decide.  Being interviewed by a prison psychologist in 1945, Rudolf Hess (1894–1987; Nazi Deputy Führer 1933-1941) claimed he’d made his bizarre attempt to secure a negotiated peace between Germany on the UK (his flight to Scotland in May 1941 on the eve of the Nazi’s invasion of the Soviet Union) because the year before “one of his astrologers had read in the stars that he was ordained to bring about peace”, adding that both Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) and Heinrich Himmler (1900–1945; Reichsführer SS 1929-1945) “had come to have an abiding belief in astrology.  It was a claim he would repeat to a journalist in the 1980s.  Despite that, as soon as the news of the flight was brought to Hitler at the Berghof (the Führer’s alpine retreat in the Bavarian Alps) the party hierarchy instantly was summoned from Berlin and the scramble was on to find the most plausible way to spin to the world an explanation why the “second man in the Reich” had delivered himself to the enemy.  In the circumstances, madness probably was the best option and the task was made easier by the British who made no attempt to exploit the defection for propaganda purposes.  Dr Joseph Goebbels (1897-1975; Nazi propaganda minister 1933-1945) put out a statement saying Hess had fallen under the influence “…of soothsayers and fortune-tellers” and had become “...a deluded, deranged and muddled idealist, ridden with hallucinations traceable to World War (ie the 1914-1918 conflict) injuries. Immediately, just to make things more plausible still, the state security apparatus (a well-oiled machine) conducted a crackdown on soothsayers and fortune-tellers, locking up many until the scandal had passed which it did remarkable quickly.

All must have been forgiven by 1945 when in the Führerbunker Goebbels, after reminding Hitler of the “miracle of the House of Brandenburg” when the death of a czarina had saved Frederick II (Frederick the Great, 1712–1786, Prussian king 1740-1786) from defeat, consulted two horoscopes kept in the files, one written on 9 November 1918 (the date on which the Weimar Republic (1918-1933) was formed), the other from 30 January 1933 (the date Hitler was appointed chancellor).  According to Goebbels, both documents predicted “the outbreak of the war in 1939, the victories until 1941, and the subsequent series of reversals, with the hardest blows during the first months of 1945, particularly during the first half of April.  In the second half of April we were to experience a temporary success.  Then there would be stagnation until August and peace that same month.  For the following three years Germany would have a hard time, but starting in 1948 she would rise again.”  Confident that “according to historical logic and justice things were bound to change”, he must have felt vindicated a few days later when the new broke of the death of Franklin Delano Roosevelt (FDR, 1882–1945, US president 1933-1945); history had given Goebbels his czarina: “Bring out our best champagne!” he commanded, adding “And get me the Fuehrer on the telephone!”  Unfortunately for Goebbels, while he might have felt he wrote his will across the sky, the stars dimmed and fell, the horoscopes no more a reliable predictor of the future than scorched shoulder blades.

Deliquesce

Deliquesce (pronounced del-i-kwes)

(1) In physical chemistry, to become liquid by absorbing moisture from the atmosphere and dissolving in it (best illustrated by the behavior of certain salts).

(2) To melt away; to disappear (used literally & figuratively).

(3) In botany, branching so the stem is lost in branches (as is typical in deciduous trees).

(4) In mycology (of the fruiting body of a fungus), becoming liquid as a phase of its life cycle.

1756: From the Latin dēliquēscere (to become liquid), the construct being dē- + liquēscere (to liquefy; liquescent).  In scientific literature, the adjective deliquescent (liquefying in air) is the most commonly used form.  It was from the Latin deliquescentem (nominative deliquescens), present participle of deliquescere (to melt away), the construct being de- + liquesco (I melt) and familiar in French also as déliquescent.  The de- prefix was from the Latin -, from the preposition (of, from (the Old English æf- was a similar prefix).  It imparted the sense of (1) reversal, undoing, removing, (2) intensification and (3) from, off.  In French the - prefix was used to make antonyms (as un- & dis- function in English) and was partially inherited from the Old and Middle French des-, from the Latin dis- (part), the ultimate source being the primitive Indo-European dwís and partially borrowed from Latin dē-.  The figurative sense of “apt to dissolve or melt away” was in use by 1837 while the verb deliquesce appears not to have been used thus until the late 1850s.  In scientific literature, the adjective deliquescent (liquefying in air) is the most commonly used form.  It was from the Latin deliquescentem (nominative deliquescens), present participle of deliquescere (to melt away), the construct being de- + liquesco (I melt) and familiar in French also as déliquescent.  The figurative sense of “apt to dissolve or melt away” was in use by 1837 while the verb deliquesce appears not to have been used thus until the late 1850s.    Deliquesce, deliquesced & deliquescing are verbs, deliquescent is an adjective, deliquescence is a noun and deliquescently is an adverb; the noun plural is deliquescences.

Deliquesce 1, oil on canvas by Tammy Flynn Seybold (b 1966).

This was the first in the Deliquesce Series, a group of works exploring the themes of transformation and conservation of energy in human forms, the artist noting being intrigued by the deceptively ephemeral nature of materials: “We think of objects - human forms included - as decaying, degrading or ‘disappearing’ but, as we know from the laws of thermodynamics, all energy is conserved - like matter, it is merely transformed from one form to another.  This work, painted with pastel-hued oils was made directly from a live model, the drips allowed organically to happen from her languid form and by using light, bright hues, I hoped to bring a spirit of optimism to this transformative process.

A footnote to the addition of deliquesce to scientific English is a tale of the chance intersection of politics and chemistry.  Dr Charles Lucas (1713–1771) was an Anglo-Irish physician who held the seat of Dublin City in the Irish Parliament and was what now would be called “a radical”, dubbed at the time “Irish Wilkes” (a nod to the English radical politician John Wilkes (1725–1797).  His early career was as an apothecary and he was shocked discover the fraud and corruption which permeated the industry and in an attempt to reform the abuses published A Short Scheme for Preventing Frauds and Abuses in Pharmacy (1735) which much upset his fellow apothecaries who were the beneficiaries of the crooked ways but the parliament did respond and created legislation regulating standards in medicines and providing for the inspection of the products; it was the first of its kind in the English-speaking world and the ancestor of the elaborate framework of rules today administered by entities such as the US FDA (Food & Drug Administration.  Encouraged, he later published Pharmacomastix, or the Office, Use, and Abuse of Apothecaries Explained (1741), the contents of which were used by the parliament to make certain legislative amendments.

However, as well as a radical, Lucas was a idealist and while the establishment was content to support him in matter of pills and potions, when he intruded into areas which disturbed the political equilibrium, they were less tolerant and, facing imprisonment, Lucas fled to the continent where he’d decided to study medicine, graduating as a doctor in 1752.  One of his first projects as a physician was a study of the composition of certain mineral waters, substances then held to possess some remarkable curative properties (something actually not without some basis).  To undertake his research he visited a number of sites including Spa, Aachen in what is now North Rhine-Westphalia and Bath in the English county of Somerset.  The material he assembled and published as An Essay on Waters. In three Parts: (i) of Simple Waters, (ii) of Cold Medicated Waters, (iii) of Natural Baths (1756) and it was in this work that the verb “deliquesce” first appeared.  Ever the “disturber” Dr Lucas’s tract upset the medical establishment in much the same way two decades earlier he’d stirred the enmity of the apothecaries, the cluster of physicians clustered around the Bath spa angered the interloper hadn’t consulted with them on a topic over which they asserted proprietorship.

In chemistry, the companion word of deliquescence is hygroscopy, both describing phenomena related to the ability of substances to absorb moisture from the surrounding environment, but they differ in extent and behavior.  Hygroscopy refers to the ability of a substance to absorb moisture from the air when exposed; hygroscopic substances can attract and hold water molecules onto their surface but tend not to dissolve.  Many salts behave thus and a well-known example of practical application is the silica gel, which, in small porous packages, is often used as a desiccant to absorb moisture in packaging. Deliquescence can be thought of an extreme form of hygroscopy (hydroscopy taken to its natural conclusion) in that a substance which deliquesces not only absorbs moisture from the air but also absorbs it to the point where it dissolves completely in the absorbed water, forming a solution.  In the natural environment, this happens most frequently when the relative humidity of the surrounding air is high and the classic deliquescent substances are salts like calcium chloride, magnesium chloride, zinc chloride, ferric chloride, carnallite, potassium carbonate, potassium phosphate, ferric ammonium citrate, ammonium nitrate, potassium hydroxide, & sodium hydroxide.  Presumably because deliquescence is the extreme form of hydroscopy it was the former which came to be used figuratively (dissolving into “nothing”) while the latter did not.

At the chemical level, hygroscopy (a class in which scientists include deliquescence as a sub-set) describes the phenomenon of attracting and holding water molecules via either absorption or adsorption (the adhesion of a liquid or gas on the surface of a solid material, forming a thin film on the surface.) from the surrounding environment.  Hygroscopy is integral to the biology of many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal.  Linguistically, hygroscopy is quirky in that the construct is hygro- (moisture; humidity), from the Ancient Greek ὑγρός (hugrós) (wet, moist) + -scopy (observation, viewing), from the Ancient Greek σκοπέω (skopéō) (to see (and the source of the Modern English “scope”) yet unlike other forms suffixed by “-scopy”, it no longer conveys the sense of “viewing or imaging”.  Originally that was the case, a hygroscope in the late eighteenth century understood as a device used to measure humidity but in a wholly organic way this use faded (“dissolving deliquescently to nothing” as it were) while hygroscopic (tending to retain moisture) & hygroscopy (the ability to do so) endured.  The modern instrument used to measure humidity is hygrometer, the construct being hygro- + -meter (the suffix from the Ancient Greek μέτρον (métron) (measure) used to form the names of measuring devices.

Belladonna

Belladonna (pronounced bel-uh-don-uh)

(1) In botany, a poisonous Eurasian perennial herb, Atropa belladonna, of the nightshade family, having purplish-red flowers and poisonous black berries (sometimes also called deadly nightshade).

(2) In clinical pharmacology, a drug from the leaves and root of this plant, containing atropine or hyoscyamine and related alkaloids; used in medicine to check secretions and spasms, to relieve pain or dizziness, and as a cardiac and respiratory stimulant; the alkaloids affect the nervous system by blocking the effects of acetylcholine.

(3) A female given name (now rare).

1590-1600: A compound word, from the Italian belladonna, from the Medieval Latin blādōna (nightshade) which may have been of Gaulish origin.  The construct was bella (a stantivization of the singular feminine form of the adjective bello (beautiful)), from the Latin bellus (beautiful, pretty, handsome, pleasant, agreeable, charming) + donna, from the Late Latin domna, a shortened variant of the Latin domina (lady, mistress of an estate or household), from dominus (master), from domus (home) and a doublet of dama (dame).  Belladonna is a noun and is capitalized if used as given name or as the taxonomic genus within the family Solanaceae–Atropa (this largely archaic except as a historic reference).

Vesicaire rempant: A print of Henbane-Belladonna, woodcut on laid paper by an unknown illustrator in Commentaires de M. Pierre Andre Matthiole medecin senois sur les six livres de Pedacion Dioscoride Anazarbeen de la matière médicinale (1572) by Dr Pietre Andrea Mattioli, published by Guillaume Roville of Lyon.

The belladonna plant seems first to have been so described by Italian physician Andrea Mattioli (1501–circa 1577) who used the form herba bella donna.  Dr Mattioli was a pioneer in botanical classification and a diligent scientist who admitted (and corrected) his errors although some of his research methods would today shock, the data he published documenting the effects of poisonous plants gained by testing them on prisoners languishing in various royal dungeons.  Apart from the value to botanists and students of medical history, his texts and the high quality artwork they included have provided much source material for social historians interested in matters as diverse as the dyes used in clothing and the produce regionally available to chefs; his texts contain the first documented evidence of tomatoes being grown in Europe.

Belladonna: Lindsay Lohan in "deadly nightshade" print fabric.

The term belladonna introduced to English by the London-based botanist John Gerarde (circa 1545-1612) who almost certainly acquired from one of Mattioli’s textbooks and quickly it seems largely to have displaced the native English forms used for the plant including dwale, (from the Old English dwola (connected with the Modern English “dull”)) & morelle (from the Old French morele, from the Latin morella (black nightshade)).  Gerarde’s epic-length (1484 page) Herball, or Generall Historie of Plantes (1597), was one of the standard texts in English until well into the seventeenth century although it was later found substantially to be a plagiarised translation of Herball, or Generall Historie of Plantes (1597) by the Flemish physician Rembert Dodoens (1517–1585), a work translated into several languages in continental Europe.

Amaryllis Belladonna.

In eighteenth century Italian use, belladonna (literally "fair lady"), was understood to convey the meaning "beautiful woman" and, supposedly, the use in botany came from the cosmetic eye-drops women made from the juice (atropic acid) of the plant known in English as "deadly nightshade", the desired quality the property of dilating the pupils to create the alluring look young ladies desired.  The mid-nineteenth century explanation that it gained the nomenclature because it was used to poison beautiful women appears to have no basis in any European legal records and was likely a folk etymology alteration.  The Italian belladonna was certainly altered by folk etymology to bella donna (beautiful lady)) the original Medieval Latin being blādōna ("nightshade" and written variously as besulidus, belbulidus, belulidus or belhulidus), the meaning shift again motivated by the cosmetic use of nightshade for dilating the eyes and the authoritative German-Austrian Romanist and linguist Ernst Gamillscheg (1887-1971) suggested it was ultimately of Gaulish origin, the Italian botanist Luigi Anguillara (actually Luigi Squalermo, circa 1512-1570) using the spelling biasola.

Pulchra domina sed tribulation: (the Latin for "a beautiful woman but trouble").

In modern use, Italian men note the legend that the more beautiful the flower of a belladonna, the more deadly its poison although this has no documented basis in botanical study it's never been disproved (were such research possible) so, according to the scientific method, it's not impossible there may be a link.  Attracted by the logic of this, the folk tradition in Italy was more beautiful a woman, the more problems she’s likely to cause, nulla altro che guai (nothing but trouble) the common vernacular form although one probably often uttered in hindsight.  Belladonna is known to have been used for medicinal purposes since Antiquity although it was the use to enlarge the pupils by women in Renaissance Italy for which lent it the romance.  The more sinister name (deadly nightshade) hints at its other chemical role and the dark berries the plant yields were known variously as “murderer’s berries”, “devil’s berries” & sorcerer’s berries, many suggesting it was the poison in William Shakespeare’s (1564–1616) Romeo and Juliet (1596) which made Juliet appear dead.  Things of course ended badly for the star-cross'd lovers but despite that belladonna remains in use as an ingredient in a number of medications, sold as a supplement and best known still for being in the drops used to dilate the eyes.

Romeo (Leonard Whiting (b 1950)) finds Juliet (Olivia Hussey (b 1951)) lying in a death-like coma after taking a potion, Franco Zeffirelli’s (1923–2019) production of Romeo and Juliet (1968).

Although so toxic that ingesting even a small quantity of its leaves or berries can be fatal (just a touch of the plant can irritate the skin), the medicinal benefits are real if the active chemicals (atropine & scopolamine) are correctly prepared and while there’s some overlap in their use, atropine as a muscle relaxant is more effective and useful also in regulating the heart rate.  In industrial applications it’s used as an antidote for insecticide poisoning and in chemical warfare agents.  Scopolamine has many sources apart from belladonna and is helpful in reducing body secretions, such as stomach acid and is an ancient sea-sickness treatment, thus the application to help with motion sickness, available in convenient skin patches.  Lethal though it can be, belladonna products are widely available as over-the-counter nutritional supplements in pump-sprays, ointments, tablets, and tincture (liquid).

(8) The acronym (as MaDD), Maladaptive Daydreaming Disorder.

(9) The acronym (as MADD), for mutually assured digital destruction: a theory of cyber-warfare whereby each participant demonstrates to the other their capacity to inflict equal or more severe damage in retaliation, thereby deterring a cyber-attack (based on the earlier MAD (mutually assured destruction), a description of nuclear warfare deterrence).

From AD to MAD, 1962-1965

The period between the addition of nuclear weapons to the US arsenal in 1945 and 1949 when the USSR detonated their first atomic bomb was unique, a brief anomaly in the history of great-power conflict.  It's possible to find periods in history when one power has possessed an overwhelming preponderance of military strength that would have enabled them easily to defeat any enemy or possible coalition but never was the imbalance of force so asymmetric as it was between 1945-1949.   Once both the US and USSR possessed strategic nuclear arsenals, the underlying metric of Cold War became the two sides sitting in their bunkers counting warheads and the centrality of that lasted as long as the bombs were gravity devices delivered by aircraft which needed to get to a point above the target.  At this point, the military’s view was that nuclear war was possible and the only deterrent was to maintain a creditable threat of retaliation and, still in the age of the “bomber will always get through” doctrine, both sides literally kept squadrons of nuclear-armed bombers in the air 24/7.  Once ground-based intercontinental ballistic missiles (ICBMs) and (especially) submarine-launched ballistic missile (SLBMs) were deployed, the calculation of nuclear war changed from damage assessment to an acknowledgement that, in the worse case scenarios made possible by the preservation of large-scale second-strike retaliatory capacity, although the "total mutual annihilation" of the popular imagination was never likely, the damage inflicted would have been many times worse and more extensive than in any previous conflict and, although the climatarian implications weren't at the time well-understood, the consequences would have been global and lasted to one degree or another for centuries.

It was thus politically and technologically deterministic that the idea of mutually assured destruction (MAD) would evolve and it was a modification of a deterrence doctrine known as AD (assured destruction) which appeared in Pentagon documents as early as 1962.  AD was intended as a way to deter the USSR from staging a first-strike against the US, the notion being that the engineering and geographical deployment of the US's retaliatory capacity was such that whatever was achieved by a Soviet attack, their territory would suffer something much worse.  To the Pentagon planners in their bunker, the internal logic of AD was compelling and was coined as a description of the prevailing situation rather than a theoretical doctrine.  To the general population, it obviously meant MAD (mutually assured destruction) and while as a doctrine of deterrence, the metrics remained the same, after 1966 when the term gained currency, it began to be used as an argument against the mere possession of nuclear arsenals, the paradox being the same acronym was also used to underpin the standard explanation of the structural reason nuclear warfare was avoided.  Just as paradoxically, while serving to prevent their use, MAD also fueled the arms race because the stalemate created its own inertia and it would be almost a decade before the cost and absurdity of maintaining the huge number of useless warheads was addressed.  MAD probably also contributed to both sides indulging in conflict by proxy, supporting wars and political movements which served as surrogate battles made too dangerous by the implications of MAD to be contested between the two big protagonists.

Maladaptive Daydreaming Disorder

There are those who criticize the existence of MADD (Maladaptive Daydreaming Disorder) as an example of the trend to “medicalize” aspects of human behaviour which have for millennia been regarded as “normal”, the implication being the sudden creation of a cohort of customers for psychiatrists and the pharmaceutical industry, the suspicion being MADD is of such interest to the medical-industrial complex because the catchment is of the “worried well”, those with sufficient disposable income to make the condition worthwhile, the poor too busy working to ensure food and shelter for their families for there to be much time to daydream.

Still, the consequences of MADD are known to be real and while daydreaming is a common and untroubling experience for many, in cases where it’s intrusive and frequent, it can cause real problems with everyday activities such as study or employment as well as being genuinely dangerous if associated with tasks such as driving or the use of heavy machinery.  The condition was first defined by Professor Eli Somer (b 1951; a former President of both the International Society for the Study of Trauma and Dissociation (ISSTD) and the European Society for Trauma and Dissociation (ESTD)) who described one manifestation as possibly an “escape or coping mechanism from trauma or abuse”, noting it may “involve long periods of structured fantasy”.  Specific research into MADD has been limited but small-scale studies have found some similarities to behavioral addictions, the commonality being a compulsion to engage in activities despite negative impacts on a person’s mental or physical health or ability to function various aspects of life. 

Despite the suggestion of similarities to diagnosable conditions, latest edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR, 2022) did not add an entry for MADD and the debate among those in the profession interested in the matter is between those arguing it represents an unidentified clinical syndrome which demands a specific diagnosis and those who think either it fits within the rubric of obsessive compulsive disorder (OCD) or is a dissociative condition.  Accordingly, in the absence of formal recognition of MADD, while a psychiatrist may decline to acknowledge the condition as a specific syndrome, some may assess the described symptoms and choose to prescribe the drugs used to treat anxiety or OCD or refer the patient to sessions of cognitive behavior therapy (CBT) or the mysterious mindfulness meditation.

Mutually Assured Digital Destruction

Authors in 2021 suggested MADD (mutually assured digital destruction) as the term to describe the strategic stalemate achieved by the major powers infecting each other’s critical (civilian & military) digital infrastructure with crippleware, logic-bombs and other latent tools of control or destruction.  The core the idea was based on old notion of “the bomber always gets through”, a recognition it’s neither possible to protect these systems from infiltration nor clean up what’s likely there and still undiscovered.  So, rather than being entirely covert, MADD instead makes clear to the other side its systems are also infected and there will be retaliation in kind to any cyber attack with consequences perhaps even worse than any suffered in the first strike.  Like the nuclear submarines with their multiple SLBMs silently which cruise the world's oceans, the strategic charm of the latent penetration of digital environments is that detection of all such devices is currently impossible; one knows they (and their SLMBs) are somewhere in firing range but not exactly where.  Oceans are big places but so is analogously is the digital environment and a threat may be in the hardware, software or the mysterious middleware and sometimes a treat can actually be observed yet not understood as such.

For individuals, groups and corporations, there's also the lure of unilateral destruction, something quite common in the social media age.  For a variety of reasons, an individual may choose to "delete" their history of postings and while it's true this means what once was viewable no longer is, it does not mean one's thoughts and images are "forever gone" in the sense one can use the phrase as one watches one's diary burn.  That was possible (with the right techniques or a power drill) when a PC sat on one's desk and was connected to nothing beyond but as soon as a connection with a network (most obviously the internet) is made and data is transferred, whatever is sent is in some sense "in the wild".  That was always true but in the modern age it's now effectively impossible to know where one's data may exist, such are the number of "pass-through" devices which may exist between sender and receiver.  On the internet, even if the path of the data packets can be traced and each device identified, there is no way to know where things have been copied (backup tapes, replica servers et al) and that's even before one wonders what copies one's followers have taken.  There may often be good reasons to curate one's social media presence to the point of deletion but that shouldn't be thought of as destruction.

Contagious & Infectious

Contagious (pronounced kuhn-tey-juhs)

(1) Capable of being transmitted by bodily contact with an infected person or object.

(2) Carrying or spreading a contagious disease; bearing contagion, as a person or animal with an infectious disease that is contagious.

(3) Tending to spread from person to person.

1350–1400: From the Middle English, from the Old French contagieus (which endures in Modern French as contagieux), from the Late Latin contāgiōsus, the construct being contāgi(ō) (contagion) (a touching, contact," often in a bad sense, "a contact with something physically or morally unclean, contagion") + -ōsus (from the Old Latin -ōsos from -ōnt-to-s  from -o-wont-to-s, the last form being a combination of two primitive Indo-European suffixes (-went- & -wont- and -to-); the suffix -ōsus was added to a noun to form an adjective indicating an abundance of that noun, much as -εις (-eis) operated in Ancient Greek).  The Latin contingere (to touch) came from an assimilated form of com (with, together) + tangere (to touch) from the primitive Indo-European tag- (to touch, handle).  Originally a technical word purely used in medicine, the figurative sense in which it could be applied to anything apt to spread from one to another (rumors etc) dates from the 1650s.  Contagious is an adjective, contagion, contagionist, contagionism, contagiousness & contagosity are nouns and contagiously is an adverb; the most common noun plural is contagions.

Infectious (pronounced in-fek-shuhs)

(1) Communicable by infection, as from one person to another or from one part of the body to another.

(2) Causing or communicating infection (of a disease) caused by pathogenic microorganism or agent, such as bacteria, viruses, or protozoa.

(3) Tending to spread from one to another.

(4) In international law, capable of contaminating with illegality; exposing to seizure or forfeiture.

(5) Diseased (wholly obsolete).

1535–1545: A compound from Middle English, the construct being infect From Middle French infect, from Latin infectivus & infectus (from the Proto-Italic enfaktos (the construct being in- (not) + factus perfect passive participle of faciō (do, make)), perfect passive participle of inficere & inficiō (dye, taint) + -ious (an alternative spelling of -ous, from the Middle English -ous, borrowed from the Old French -ous and -eux, from the Latin -ōsus (full, full of) and a doublet of -ose in unstressed position; the suffix was used to form adjectives from nouns, to denote possession or presence of a quality in any degree, commonly in abundance).  The sense of "catching diseases, having the quality of spreading from person to person, communicable by infection" dates from the 1540s which by the early seventeenth century had spread to emotions, actions et al; earlier in the same sense were infectious, common by the late fifteenth century and infective from a hundred-odd years earlier.  The most novel adaptation of the word was the sense of "captivating", noted first in the 1650s.  Disinfectant (agent used for destroying the germs of infectious diseases) dates from 1837 from the French désinfectant (1816), noun use of present participle of désinfecter, or else from the adjective in English (by 1827) in the sense of "serving to disinfect".  Infectious is an adjective, infection, infectionist, infectionism, infector & infectiousness are nouns and infectiously is an adverb; the most common noun plural is infections.  

Sort of interchangeable

Increasing the risk of contagion: Lindsay Lohan sneezing.

Except for specialists such as virologists or epidemiologists, contagious and infectious can probably be used interchangeably although, when used in the figurative sense, many style guides suggest contagious should be used if referring to something undesirable whereas infectious should be preferred if speaking of the pleasantly irresistible quality of something.  There’s no etymological basis for this; it’s just a convention of use.  Something contagious is a thing which can be transmitted from one living being to another through direct or indirect contact.  Although infectious is also used to describe the process, it has a slightly different meaning in that it refers to diseases caused by infectious agents (such as or SARS-CoV-2 which causes COVID-19) not normally present in the body.  While the notion of contagiousness dates at least from Antiquity, the idea of infectious diseases is more modern, arising only after the publication of the germ theory of disease, not proposed until the late nineteenth century.  Contagious and infectious are also used to refer to people who have communicable diseases at a stage at which transmission to others is likely.

Reducing the risk of contagion: Lindsay Lohan in facemask (although the twin one-way, non-return valves of these masks limit their effectiveness in reducing the risk of infecting others).

For those in the relevant professions however, the difference between the two is significant.  “Infectious” is a description a disease-causing agent’s (typically a virus, bacterium or parasite) ability to enter, survive, and multiply in a host organism; by definition any infectious disease is caused by the presence and activity of such agents.  The best-known infectious diseases include the various strains of influenza (commonly clipped to “the flu”), tuberculosis (TB), malaria, hepatitis, AIDS (HIV the agent) and of course COVID-19 (Sars-COV-2 the agent).  “Contagious” refers to the ability of a disease to spread from one host (such as a bacterium, human or other animal) to another through a variety of vectors including (1) direct contact (shaking hands, kissing, sexual contact (these sometimes sequential)), (2) indirect contact (such as touching a door knob contaminated with the infectious agent using one’s hand which then introduces the agent to the system via the eyes, nose or mouth), (3) airborne transmission (usually by breathing in droplets when an infected person in close vicinity coughs or sneezes) or (4) through a third party (such as animal scratch or bite).

A contagious disease is a sub-set of infectious diseases which can (some more easily than others) be transmitted from one host to another.  Examples of contagious diseases include measles, chickenpox (and other –pox types), COVID-19 and most commonly, the endemic common cold.  While all contagious diseases are infectious, not all infectious diseases are necessarily contagious; tetanus is an infectious disease caused by the bacterium Clostridium tetani, but it is not contagious from host to host.

Rational (pronounced rash-nl (U) or rash-uh-nl (non-U))

(1) Agreeable to reason; reasonable; sensible.

(2) Having or exercising reason, sound judgment, or good sense.

(3) Of a person or their personal characteristics, being in or characterized by full possession of one's reason; sane; lucid; healthy or balanced intellectually; exhibiting reasonableness.

(4) Endowed with the faculty of reason; capable of reasoning.

(5) Of or relating to, or constituting reasoning powers.

(6) Proceeding or derived from reason or based on reasoning.

(9) In chemistry, expressing the type, structure, relations, and reactions of a compound; graphic; said of formulae.

(10) In physics, expressing a physical object.

(11) In the philosophy of science, based on scientific knowledge or theory rather than practical observation.

(12) The breastplate worn by Israelite high priests (historic references only).

1350-1400: From the Old French rationel & rational, from the Middle English racional, from the Late Latin ratiōnālis (of or belonging to reason, rational, reasonable; having a ratio), the construct being ratiōn (stem of ratiō (reason; calculation)) + -ālis.  The –alis suffix was from the primitive Indo-European -li-, which later dissimilated into an early version of –āris and there may be some relationship with hel- (to grow); -ālis (neuter -āle) was the third-declension two-termination suffix and was suffixed to (1) nouns or numerals creating adjectives of relationship and (2) adjectives creating adjectives with an intensified meaning.  The suffix -ālis was added (usually, but not exclusively) to a noun or numeral to form an adjective of relationship to that noun. When suffixed to an existing adjective, the effect was to intensify the adjectival meaning, and often to narrow the semantic field.  If the root word ends in -l or -lis, -āris is generally used instead although because of parallel or subsequent evolutions, both have sometimes been applied (eg līneālis & līneāris).  The use to describe the breastplate worn by Israelite high priests was from the Old French rational, from the Medieval Latin ratiōnāle (a pontifical stole, a pallium, an ornament worn over the chasuble), neuter of the Latin rationalis (rational).  The spelling rationall is obsolete.  Rational is a noun & adjective, rationalizing is a noun & verb, rationalize & rationalized are verbs, rationalism , rationalness & rationalizer are nouns and rationally is an adverb; the noun plural is rationals.  The rarely used adjective hyperrational means literally “extremely rational” and can be used positively or neutrally but it’s applied also negatively, usually as a critique of “economic rationality”.

In something of a departure from the usual practice in English, “antirational”, “nonrational” & “irrational” (there are hyphenated forms of both) are not necessarily synonymous.  Antirational describes something or someone who is or acts in a way contrary to the rational while arational (often in the form arationality) is a technical term used in philosophy in the sense of “not within the domain of what can be understood or analyzed by reason; not rational, outside the competence of the rules of reason” an applied to matters of faith (religious & secular).  Nonrational (used usually in the hyphenated form) is literally simply the antonym of rational (in most senses) but now appears most often in the language of economics where it’s used of decisions made by actors (individual, collective & corporate) which are contrary to economic self-interest.  Irrational can be used as another antonym but it’s also a “loaded” adjective which carries an association with madness (now called mental illness) while in mathematics (especially the mysterious world of number theory) it’s the specific antonym of the “ration number” and means a “real number unable to be written as the ratio of two integers”, a concept dating from the 1560s.

The adjective rational emerged in the mid-1400s and was was a variant of the late fourteenth century racional (“pertaining to or springing from reason” and of persons “endowed with reason; having the power of reasoning”, from the Old French racionel and directly from the Latin rationalis (of or belonging to reason, reasonable) from ratio (genitive rationis) (reckoning, calculation, reason).  By the 1560s it was picked up in mathematics to mean “expressible in finite terms” before becoming more precisely defined.  The meaning “conformable to the precepts of practical reason” dates from the 1630s.  The adverb rationally was from the same source as ratio and ration; the sense in rational is aligned with that in the related noun reason which got deformed in French.  The noun rationality by the 1620s was used in the sense of “quality of having reason” and by mid-century that had extended to “fact of being agreeable to reason”, from the French rationalité and directly from the Late Latin rationalitas (reasonableness, rationality (the source also for the Spanish racionalidad and the Italian razionalita), from the Latin rationalis (of or belonging to reason, reasonable).  As late as the early fifteenth century racionabilite (the faculty of reason) was in Middle English, from the Latin rationabilitas.

By the 1820s, the noun rationalization was in use in the sense of “a rendering rational, act of subjection to rational tests or principles”, the specific modern sense in psychology in reference to subconscious (to justify behavior to make it seem rational or socially acceptable) adopted by the profession early in the twentieth century.  The verb rationalize (explain in a rational way, make conformable to reason) dates from the mid eighteenth century although the sense familiar in psychology (to give an explanation that conceals true motives) came into use only in the 1920s on the notion of “cause to appear reasonable or socially acceptable” although decades earlier it had been used with the intransitive sense of “think for oneself, employ one's reason as the supreme test”.  The use in psychology endured but “rationalize” also came into use in applied economics with the meaning “to reorganize an industry or other commercial concern to eliminate wasteful processes”.  That seems to have come from US use although the first recorded entry was the Oxford English Dictionary’s (OED) supplementary edition in 1927.  In this context, it became a “vogue word” of the inter-war years of both sides of the Atlantic although it fell from favour after 1945 as the vogue shifted to “integrate”, “tailor”, “streamline” and that favourite of 1970s management consultants: the “agonizing reappraisal”.  However, in the 1980s & 1990s, “rationalize” gained a new popularity in economics and (especially) the boom industry of financial journalism, presumably because the “economic rationalists” coalesced during the Reagan-Thatcher era as the dominant faction in political economy.

Many have their own favourite aspect of Sigmund Freud’s (1856-1939) theories but one concept which infuses mush of his work is the tussle in the human psyche between the rational and irrational.  Freud’s structural model consisted of the three major components: id, ego & superego, the elements interacting and conflicting to shape behavior and personality.  The id was the primitive & instinctual part containing sexual and aggressive drives; operating on the pleasure principle, it seeks seeking immediate gratification and pleasure.  Present even before birth, it’s the source of our most basic desires and in its purest processes is wholly irrational, focused on wants and not the consequences of actions.

Concept of the id, ego & superego by the Psych-Mental Health Hub.

The rational was introduced by the ego, something which developed from the id and was the rational, decision-making part of the mind which balanced the demands of the id and the constraints of reality.  As Freud noted, implicit in this interaction was that the ego repressed the id which obviously was desirable because that’s what enables a civilized society to function but the price to be paid was what he called “surplus repression”.  That was a central idea in Freud's later psychoanalytic theory, exploring the consequences of the repression of innate, instinctual drives beyond that which was necessary for the functioning of society and the individual: the rational took its pound of flesh.  Discussed in Civilization and its Discontents (1930), “primary repression” was essential to allow the individual to adapt to societal norms and function in a civilized society while “surplus repression” was the operation of these forces beyond what is required for that adaptation.  Freud identified this as a source of psychological distress and neurosis.

Lindsay Lohan’s early century lifestyle made her a popular choice as a case-study for students in Psychology 101 classes studying the interaction of the rational and irrational process in the mind.  Most undergraduates probably enjoyed writing these essays more than had they been asked to analyse Richard Nixon (1913-1994; US president 1969-1974), America’s other great exemplar of the struggle.

It was the ego which mediated between the id, the superego, and the external world, making possible realistic and socially acceptable decisions, essentially by making individuals consider the consequences of their actions.  The superego developed last and built a construct of the morality, ethical standards & values internalized from parents, the education system, society and cultural norms; operating on the “morality principle”, the superego one of the “nurture” parts of the “nature vs nurture” equation which would for decades be such an important part of research in psychology.
