Insoluble

Insoluble (pronounced in-sol-yuh-buhl)

(1) A substance which cannot be dissolved, broken down or dispersed.

(2) That which cannot be solved; unsolvable; insolvable.

(3) That which cannot be explained; mysterious or inexplicable.

(4) In chemistry, a substance incapable of dissolving in a solvent.

1350-1400: From the Middle English insoluble (indestructible, unable to be loosened), from the Old French insoluble or the Latin insolūbilis (that which cannot be loosened), the construct being in (not) + solubilis (soluble) which replaced the Middle English insolible; Middle French borrowed the word from the Latin as insoluble.  In the sciences, the noun insolubility in the sense of “incapability of dissolving in a liquid” dates from 1754 (insoluble having conveyed that since 1713), the Late Latin insolubilitas having previously been used and from 1791 it replaced the Latin insolubilis (that cannot be loosened) although in the early seventeenth century it’d been used of the marriage vow to mean "that cannot be dissolved".  The curious (and in many way annoying as such thing in English are) parallel meaning "that which cannot be solved" dates from 1722 and etymologists think it likely a separate formation from the earlier senses.  The related adjective irresolvable was from the 1650s and was from an assimilated form of in- (not, opposite of), the meaning "that which cannot be resolved into parts" emerging after 1785.  Insoluble is a noun & adjective, insolubility is a noun and insolubly is an adverb; the noun plural is insolubles.

In chemistry, insoluble has the precise technical meaning “incapable of dissolving in a solvent” and while it’s actually rare for absolutely no solute to dissolve at all, many substances are poorly soluble although a compound may be insoluble in one solvent yet fully miscible in another.  There’s also the influence of external factors, most notable temperature; increasing temperature frequently improves the solubility of a solute.  The figurative sense (that which cannot be solved; unsolvable; insolvable) is actually used less than other words or phrases which convey the idea, doubtlessly because of the parallel meaning.  Some claim that in Medieval scholarship, it was a tacit conviction among the learned that the insoluble question did not exist and that all that was ever required was to find the right man whose studies were so deep that he would eventually deduce the answer.  It’s a modern-sounding idea and recalls some of the optimistic phases the United States went through in the twentieth century; probably few think like that now.

Dr Rowan Williams (b 1950; Archbishop of Canterbury, 2002-2012) and Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022), discussing insoluble problems during the papal visit to the UK, Lambeth Palace, London, September 2010

One who probably never felt quite like that but may at times have allowed himself the odd, brief moment of optimism was former Archbishop of Canterbury Dr Rowan Williams, a literary critic and one-time Professor of Divinity at Oxford although his decade in Lambeth Palace seems to have cured him of that.  In late 2008, Dr Williams took a two month summer sabbatical to finish a book about his literary hero, the Russian novelist Fyodor Dostoevsky (1821-1881) which was published as Dostoevsky: Language, Faith and Fiction.  Those few weeks may have been among the happiest of his life, later reflecting that “It was a wonderful experience actually, just being able to get up in the morning and write instead go to committees and answer letters and try to solve insoluble problems in the church.”  To the suggestion that prayer might provide answers to at least some of those insoluble problems he replied “I'll do just that.”  Ten years on, there little indication his prayers were answered.

Lambeth

Lambeth (pronounced lam-bith)

(1) A south London suburb, the location of Lambeth Palace, the seat of the Archbishop of Canterbury.

(2) A slang term for the hierarchy of the Church of England.

The name Lambeth embodies hithe, a Middle English word for a landing on the river.  Lambeth Palace has for some eight-hundred years been the official London residence of the Archbishop of Canterbury.  It sits on the south bank of the Thames, a quarter mile (400m) south-east of the Palace of Westminster, which contains the houses of parliament, on the opposite bank.

Rowan Williams (b 1950; Archbishop of Canterbury 2002-2012) and Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022) chat at Lambeth Palace.

The Lambeth Conference

The Lambeth Conference is a (nominally) decennial assembly of bishops of the Anglican Communion convened by the Archbishop of Canterbury.  There have been fourteen Lambeth Conferences, the first in 1867.  The Anglican Communion is an international association of autonomous national and regional churches, not a governing body and the office of Archbishop of Canterbury is in no way analogous with the Roman Catholic Pope.  The conferences serve a collaborative and consultative function and are said to express “…the mind of the communion" on issues of the day. Resolutions passed at a Lambeth Conference are without legal effect, but can be influential.

Conferences were never the pure and high-minded discussions of ethics, morality and theology some now appear to believe characterized the pre-modern (in this context those held prior to 1968) events.  Agenda and communiqués from all conferences have always included the procedural, administrative and jurisdictional although in recent years, they’ve certainly reflected an increasingly factionalized communion rent with cross-cutting cleavages, first over the ordination of women and of late, homosexual clergy.  During the 1998 conference, Bishop Chukwuma (b 1954) of Nigeria attempted to exorcise "homosexual demons" from the soul of Nigerian-born Richard Kirker (b 1951), a British priest and general secretary of the Lesbian and Gay Christian Movement.  Recalling probably Ephesians 4:32 or perhaps the more cautionary Matthew 6:15, Kirker forgave him.

The spirit of Kirker notwithstanding, at this point, the disagreements seem insoluble.  The poisonous atmosphere at, and in the aftermath of, the last conference in 2008 did not enhance the image of the church and a typically Anglican solution to avoid a repetition in 2018 seemed to have emerged.  In 2014, in answer to the suggestion he had cancelled the 2018 conference, Archbishop Justin Welby (b 1956; 105th Archbishop of Canterbury 2013-), in a statement worthy of any of his predecessors, responded by stating, "As it hasn’t been called, it can’t have been cancelled."

A communiqué issued after the primates' meeting in January 2016, noted the bishops had accepted the archbishop’s proposal the fifteenth conference should be held in 2020.  However, because of the COVID-19 pandemic, it was in March 2020 decided to postpone the conference to the summer of 2021 but the virus proved elusive and by July, the delay had been extended to 2022.  The first epistle of Peter has been chosen as the biblical focus for the conference, the theme of which is said to be what it means to be “God’s Church for God’s World”.  The apostle Peter wrote this epistle to give comfort to Christians suffering persecution from non-believers, hoping to encourage them to live pure lives despite their vicissitudes.

Peter didn’t sugar-coat the message (1 Peter 4:12-19), making it clear that for Christians, suffering is actually a participation in the sufferings of Christ and is an occasion for rejoicing, helpfully adding that in the midst of the suffering, the Holy Spirit rests upon those who are suffering, this being a great consolation.  He further explains that God uses suffering to purify the Christian community, God's household.  God uses the abuse that pagans unjustly heap on Christians to prepare his people for the return of Christ and warns people not to be surprised at the fiery ordeal that will come upon them as followers of Jesus.  Actually, they should be both grateful and happy and thus glorify God, for if they share in Christ’s sufferings it means they will also share in his glory.

In a world beset by fire, flood, pestilence and plague, 1 Peter seems a good theme to loom over a Lambeth Conference.  Whether or not Christians beyond the Kent conference rooms will long note the message, it probably will resonate with Archbishop Welby’s predecessor, Rowan Williams (Baron Williams of Oystermouth, b 1950; 104th Archbishop of Canterbury, 2002-2012).  During his tenure at Lambeth, Dr Williams probably felt more ignored than persecuted by non-believers, finding the internecine squabbles of the believers in the Anglican factions rather more tiresome.  Declaring the problems in the church “insoluble” he seemed not unhappy to be leaving Lambeth to return to his study and write about Dostoevsky.  A generous spirit, he will have wished his successor well.

Niche

Niche (pronounced nĭch (U) or nēsh (Non-U))

(1) In architecture, a cavity, hollow or recess, generally within the thickness of a wall and usually semi-circular in plan and arched, for a statue, bust, or other erect ornament; in interior decorating the synonym is nook.

(2) Any similar recess, such as one in a rock face.

(3) Figuratively, any similar position such as (1) a place or position suitable or appropriate for a person or thing or (2) a distinct or specialised segment of a market.

(4) In ecology, the role of a plant or animal within its community and habitat which determines its activities and relationships with other organisms.

(5) In contrast radiography, an eroded or ulcerated area.

(6) In Islam, an arrow woven into a Muslim prayer rug pointing in the direction of Mecca (qibla).

(7) In the funeral industry, as cremation niche; a columbarium.

1605-1615: From the Middle English niche (shallow recess in a wall), probably from the Old & Middle French niche (recess (for a dog), kennel), a back formation from nicher (to make a nest), from the unattested Vulgar Latin nīdiculāre, from the Classical Latin nīdus (nest), the words niche & nicher enduring in Modern French.  Niche was a doublet of nidus and nide via the Latin and the related nest via the primitive Indo-European and was related also to nyas.  Some etymologists are not convinced by the notion of a direct Latin root and trace the French niche (recess (for a dog), kennel) to a fourteenth century borrowing from the Italian nicchia (niche, nook) derived from nicchio (seashell).  The dissidents note the link to the Latin mitulus (mussel) but also the lack of any documentary evidence for the change of -m- to -n-.  The origin in the Old French noun derived from nichier is said to come via the Gallo-Romance nidicare from Latin nidus (nest) but it remains one of those insoluble disputes in linguistics.  The figurative sense was first recorded in 1725, the use in ecology dating from 1927 and contemporary coinings like niche market, multi-niche & niche player are all from the twentieth century.  Niche is a noun and nicher, nichering & nichered are verbs; the noun plural is niches.

Pronunciation

While the origin of niche is of interest only to the profession, the dispute over pronunciation has a wider audience: nĭch (the U version and phonetically nich) or nēsh (non-U and neesh)?  Many dictionaries (especially the descriptive) list both but those which offer only one (the prescriptive) insist on nitch.  The descriptive (and thus linguistically promiscuous) Merriam-Webster’s on-line presence lists several pronunciations for niche: nitch, neesh and nish, in a deliberate attempt to reflect English as it’s actually spoken while Webster’s more prescriptive print edition continues to insist on nich.  The Gallic-influenced neesh is said now to be the preferred US use.

Lindsay Lohan in Falling for Christmas (left) and Irish Wish with Triumph TR4 and body double (right).  In film, a niche differs from a franchise in that the former is a conceptual genre and independent of the characters, the latter thematic and generally dependent on the continuity of at least one character.  Lindsay Lohan’s two recent Netflix productions, Falling for Christmas (2022) & Irish Wish (slated for 2023) are in the rom-com (romantic comedy) niche.

There are two types of dictionaries: prescriptive and descriptive and most modern dictionaries are descriptive, meaning they attempt to describe the language as it’s used, including, explicitly or by implication, all pronunciation variants of a word used by educated speakers.  This approach does upset some purists but this is how English has always evolved, a slut of a language which picks up words which seem useful, uses them as required and dumps them when they’re outlived their usefulness.  It’s tempting to suggest those who read Anthony Trollope (1815-1882) say nith, those who watch TikTok prefer neesh but if ever that was true, it may no longer be but, when in doubt, stick to the classics: niche should be pronounced nich.

Niche, nitch & the W113 notch

So things started with niche and later there came nitch which was (1) an alternative form of knitch (a small bundle), (2) a blend of nick + notch (a dialectal form meaning "a small notch or incision") and (3) a simple misspelling of niche which caught on.  In the collector car market there are many niches and while there’s overlap and some multi-niche players, niches are often siloed, one being the Mercedes-Benz W113.  The W113 was a small roadster of spare, elegant lines which was produced in 3 versions (230 SL, 250 SL & 280 SL) between 1963-1971 and is known among the cognoscenti as the “pagoda” an allusion to the unusual curve of the roof of the detachable hard-top.  Upon release, the slight concave effect was sometimes misunderstood and the factory was at pains to point out it was the side windows which had been raised, not the centre of roof lowered.  The look had great aesthetic appeal but it also (1) permitted easier ingress & egress and (2) enhanced structural rigidity, allowing the use of thinner pillars which provided better visibility.  The successor roadster (the R107, 1971-1989) used a similar roof design but the pagoda moniker is unique to the W113.

1971 Mercedes-Benz 280 SL in Silver over Black Leather (left) and 1970 280 SL in Midnight Blue over Blue Leather (right).  

Also unique to the W113 niche is the cult of the notch.  Part of the charm of the W113 and a proof it came from a time when Mercedes-Benz were rather more “hand-made” than now, were the leaded-seam “fender notches”, small creases in the fender, inboard of the headlights, which workers on the assembly line hand-shaped with tin, their purpose being to ensure the notch matched both the kink in the headlight surround and the crease on the outside of the fender.  That ensured perfect alignment (this was a time when the factory took seriously such intricate details of quality control) but were thought at the time just part of the manufacturing process and not publicized.

By their notches shall they be known: Headlight notches (left & right) on US market 1969 Mercedes-Benz 280 SL in Anthracite Grey Metallic over Gray Leather.  

Thus, in the decades before the W113 became a collectable and long before originality became a fetish, when replacing fenders (supplied from the factory without a notch), repair shops unfamiliar with the breed sometimes wouldn’t fashion a notch one to match the one replaced, unaware perhaps even of their existence (and "asymmetric" W113s have been seen with an single notch).  There were tales too of the factory’s notches even being smoothed-out as a “fix” by W113 neophytes thinking the grooves a manufacturing defect or the result of accident damage although these stories may be apocryphal.  However, those who have had a replacement fender “notched” exactly to match the one removed may still not satisfy the originality police because the inner fender spot welds which affix the fender to the structure are said to have been done in a manner almost impossible to replicate.  It’s metal so it can be done but it’s not easy to convince the experts who judge such things and they are tough judges.

Hardwired

Hardwired (pronounced hahrd-whyid)

(1) In electronics, built into the hardware.

(2) In mainframe computing, a terminal connected to the CPU(s) by a direct cable rather than through a switching network.

(3) In the behavioral sciences, a cluster of theories pertaining to or describing intrinsic and relatively un-modifiable patterns of behavior by both humans and animals.  Published work describes genetically determined, instinctive behavior, as opposed to learned behavior.

(4) In computer programming, a kludge temporarily or quickly to fix a problem, done historically by bypassing the operating system and directly addressing the hardware (assembly language).

(5) Casual term for anything designed to perform a specific task.

1969:  A compound word: hard + wired.  Hard was from the Middle English hard from the Old English heard, from the Proto-Germanic harduz, derived ultimately from the primitive Indo-European kort-ús from kret (strong, powerful).  Cognate with the German hart, the Swedish hård, the Ancient Greek κρατύς (kratús), the Sanskrit क्रतु (krátu) and the Avestan xratu.  Wire was from the Middle English wir & wyr from the Old English wīr (wire, metal thread, wire-ornament) from the Proto-Germanic wīraz (wire) from the primitive Indo-European wehiros (a twist, thread, cord, wire) from wehy (to turn, twist, weave, plait).  The suffix ed was used to form past tenses of (regular) verbs and in linguistics is used for the base form of any past form.  It was from the Middle English ede & eden, from the Old English ode & odon (a weak past ending) from the Proto-Germanic ōd & ōdēdun. Cognate with the Saterland Frisian ede (first person singular past indicative ending), the Swedish ade and the Icelandic aði.  The earliest known citation is from 1969 although there are suggestions the word or its variants had been used earlier, both in electronics and forms of mechanical production, the word migrating to zoology, genetics and human behavioral studies in 1971. The spellings hardwired, hard wired and hard-wired are used interchangeably and no rules or conventions of use have ever emerged.

The coming of the wireless hardware devices really pleased many women who, for whatever reason, often showed an aversion to the sight of cables, whether lying across the floor or cluttering up their desks, noting their curious way of attracting dust and, adding insult to injury, an apparently insoluble tendency to tangle.  There are though still genuine advantages to using a cabled connection and although wireless headphones have long been the preferred choice of most, there remains a niche in which the old ways still are the best.  The advantages include (1) typically superior sound quality (which obviously can be subjective but there are metrics confirming the higher fidelity), (2) no batteries required, (3) inherently lower latency (thus ideal for gaming, and audio or video editing because of the precision in synchronization, (4) simplified internal construction which should mean lower weight for equivalent dimensions mass and improved reliability and (5) close to universal compatibility with any device with headphone jack or adapter.  The drawbacks include (1) one’s physical movement can be limited by the tethering (thus not ideal for workouts), (2) cables can be prone to damage, (3) cables can be prone to snags & tangles, (4) compatibility emerging as an issue on mobile devices with an increasing number lacking headphone jacks or demanding adaptors.  Of course for some the existence of Bluetooth pairing will be a compelling reason to go wireless and it has to be admitted the modern devices are now of such quality that even lower cost units are now good enough to please even demand audiophiles.

SysCon

IBM explains by example.

In the pre-modern world of the mainframes, there might be a dozen or thousands of terminals (a monitor & keyboard) attached to a system but there was always one special terminal, SysCon (system console), hardwired to the central processor (something not wholly synonymous with the now familar CPU (central processing unit) in PCs.  Unlike other terminals which connected, sometimes over long distances, through repeaters and telephone lines, SysCon, often used by system administrators (who sometimes dubbed themselves "SysCon" the really nerdy ones not using capitals), plugged directly into the core CPU.  When Novell released Netware in 1983, they reprised SysCon as the name of the software layer which was the core administration tool.

Google ngram: The pre-twentieth century use of "hardwired" would have been unrelated to the modern senses.  Because of the way Google harvests data for their ngrams, they’re not literally a tracking of the use of a word in society but can be usefully indicative of certain trends, (although one is never quite sure which trend(s)), especially over decades.  As a record of actual aggregate use, ngrams are not wholly reliable because: (1) the sub-set of texts Google uses is slanted towards the scientific & academic and (2) the technical limitations imposed by the use of OCR (optical character recognition) when handling older texts of sometime dubious legibility (a process AI should improve).  Where numbers bounce around, this may reflect either: (1) peaks and troughs in use for some reason or (2) some quirk in the data harvested.

In recent decades, the word “hardwired” has become a popular form, used figuratively to describe traits, behaviors, or tendencies believed to be innate, automatic, or deeply ingrained, the idea being things “permanently programmed into a human or animal”, on the model of the fixed circuitry in an electronic device.  Although probably over-used and sometimes with less than admirable precision, the term has come to be well-understood as referring to things (1) biologically pre-determined (instincts, reflexes), (2) psychologically ingrained (personality traits, cognitive biases) or (3) culturally conditioned but so deeply entrenched they appear intrinsic.  Even in professions such as medicine, psychiatry & psychology, all noted for their lexicons of technical terms with meanings often (in context) understood only by those with the training, in colloquial use it has become a popular metaphor.  It seems also to be an established element in academic writing because it’s such convenient verbal shorthand to convey meaning.  In that sense, it’s an acceptable metaphor in a way the phrase “it’s in the DNA” is not because that can be literal in a way “it's hardwired” cannot because living organisms have no wires.  DNA (deoxyribonucleic acid) is the famous double helix of polymers which constitute the so-called “building blocks” of life and sometimes the expression “it’s in the DNA” simply is incorrect because what’s being discussed is not connected with the double helix and it would be better to say “it’s hardwired” because the latter is vague enough to convey the idea without be so specific as to mislead.  The best use of the metaphoric “hardwired” is probably in neuroscience because the brain’s neural circuits may directly be compared with electronic circuitry.  The difficulty with using “hardwired” in the behavioural sciences is that very vagueness: it’s not helpful in suggesting where the lines exists between what’s determined by evolution and what are an individual’s temperamental traits.  That said, it remains a useful word but, used carelessly, it can overstate biological determinism.

Indigo

Indigo (pronounced in-di-goh)

(1) A blue dye obtained from various plants, especially of the genus Indigofera, or manufactured synthetically.

(2) A descriptor of color indigo, widely defined commercially and ranging from a deep violet blue to a dark, greyish blue (sometimes as "indigo blue").

(3) In technical use, as indigo blue (also casually referred to as indigotin or indigo), a dark-blue, water-insoluble, crystalline powder (C₁₆H₁₀N₂O₂), having a bronze-like luster, the essential coloring principle of which is contained along with other substances in the dye indigo and which can be produced synthetically.

(4) Any of numerous hairy plants belonging to the genus Indigofera, of the legume family, having pinnate leaves and clusters of usually red or purple flowers (the best-known of the plants including Amorpha (false indigo), Baptisia (wild indigo), and Psorothamnus and Dalea (indigo bush)).

(5) In zoology, as the Eastern indigo snake, the common name for the Drymarchon couperi.

(6) In zoology, as the indigobird (or indigo bird), any of various African passerine birds of the family Viduidae.

(7) A (rarely used) female given name.

1550s: The spelling change from indico to indigo happened in the 1550s, used originally in the sense of the “blue powder obtained from certain plants and used as a dye”.  Indigo was from the Spanish indico and the Portuguese endego (the Dutch indigo exclusively was from Portuguese), all from the Latin indicum (indigo), from the Ancient Greek ἰνδικόν (indikón) (Indian blue dye (literally “Indian substance”)), a neuter of indikos (Indian), from the Indic Ἰνδία (Indía).  Indic is a subgroup of the Indo-Iranian branch of Indo-European languages that includes Sanskrit, Hindi, Urdu, Bengali, and many other languages of India, Pakistan, and Sri Lanka; Indo-Aryan.  It replaced the late thirteenth century Middle English ynde, from the thirteenth century Old French inde (indigo; blue, violet), again from the Latin indicum; the earlier name in Mediterranean languages was annil or anil.  In the magical-realist novel Sassafrass, Cypress & Indigo (1982) by African American feminist Ntozake Shange (1948–2018), the name of one protagonist is Indigo and it continues to be used as a given name for females.  Indigo is a noun & adjective and indigotic is an adjective; the noun plural is indigos or indigoes.

Sir Issac Newton, light and the "two prism experiment" 

As used to refer to “the color of indigo”, use dates from the 1620s and in 1704 Sir Isaac Newton (1642–1727) adopted indigo as the name for the darkest of the two blues on his spectrum of the visible colors of light.  Newton identified seven colors in the spectrum of light (red, orange, yellow, green, blue, indigo and violet) and although he was a great figure of science and the Enlightenment, he was also an alchemist and theologian who published notable works of Biblical scholarship, something which may account for the choice of seven, that number being of some significance in scripture.  By objective analysis, there are probably six colors in the spectrum, but Newton’s world view which attributed something mystical to the number demanded there be seven.  He decided in advance light was made of seven colors but his experimental method to vindicate this theory of differential refraction was sound.  The orthodox view of the time suggested a prism acted on any incident light to add colour; Newton wished to prove what was really happening was a process of separation refraction.  For this, he used two prisms.  The first produced the full spectrum of colors and from this Newton isolated narrow beams of light of a single colour, directing them at the second prism, finding that for all colors, there was no further change as the beam passed through the second prism: “When any one sort of Rays hath been well parted from those of other kinds, it hath afterwards obstinately retained its colour, not with standing my utmost endeavours to change it.”

Lindsay Lohan shopping at Indigo Seas, North Robertson Boulevard, Los Angeles, February 2009.  Most fashion houses would regard her dress’s blue as “too blue” to be within the indigo range but to illustrate how far (in commercial use) indigo can travel, some would call this "Spanish indigo" (Hex: #003C92; RGB: 0, 60, 148).

Darker than violet: Canva's example of the classic (#4b0082) indigo.

Although some use extends even to grey, generally, indigo is a range of bluish-purples between blue and violet in the color wheel and such is the reverence for Newton it’s considered still one of the seven spectral colors (indigo’s hex code is #4B0082),  In this, although it may visually be dubious, indigo has fared better than the unfortunate Pluto, the International Astronomical Union (IAU) voting in 2006 to re-classify Pluto as a dwarf planet on the basis the icy orb failed to meet a set of criteria which the IAU claimed had been accepted for decades.  The IAU are a bunch of humorless cosmic clerks, something like the Vogons ("...not actually evil, but bad-tempered, bureaucratic, officious and callous.") in Douglas Adams' (1952–2001) Hitchhiker's Guide to the Galaxy (1979-1992) and, not affected by romantic tales, have refused to restore Pluto to planethood, leaving it desolate, lonely and cold; it's the solar system’s emo.  Indigo place on the spectrum seems however secure and according to Canva (an internet authority on color), it’s the color of devotion, wisdom, justice, and higher knowledge; tied to intuition and what is not seen; it is also considered spiritual.  More prosaically, Canva list indigo as hexadecimal #4b0082, with RGB values of Red: 29.4, Green: 0, Blue: 51 and CMYK values of Cyan: 0.42, Magenta: 1, Yellow: 0, Black (K):0.49.  The decimal value is 4915330.  It has a hue angle of 274.6 degrees, a saturation of 100% and a lightness of 25.5%. #4b0082 color hex could be obtained by blending #9600ff with #000005. Closest websafe color is: #330099.

Um Antropólogo em Martem, Portuguese edition of An Anthropologist on Mars: Seven Paradoxical Tales (1995) by Dr Oliver Sacks.  The color used for the cover is “too purple” to be within the indigo range.  Noting the long uncertainty about just what the hue of indigo really was, the British neurologist and author Oliver Sacks (1933–2015) told an interviewer:

“I had been reading about the color indigo, how it had been introduced into the spectrum by Newton rather late, and it seemed no two people quite agreed as to what indigo was, and I thought I would like to have an experience of indigo.  And I built up a sort of pharmacological launch-pad with amphetamines and LSD (lysergic acid diethylamide, better known as “acid”) and a little cannabis on top of that, and when I was really stoned I said, 'I want to see indigo now.'  And as if thrown by a paintbrush, a huge pear-shaped blob of the purest indigo appeared on the wall.  Again it had this luminous, numinous quality; I leaped toward it in a sort of ecstasy.  I thought, 'This is the color of heaven.' ... I thought maybe this is not a color which actually exists on the Earth, or maybe it used to exist or no longer exists. All this went through my mind in 4 or 5 seconds, and then the blob disappeared, giving me a strong sense of loss and heartbrokenness, and I was haunted a little bit when I came down, wondering whether indigo did exist in the real world.”

Piktochart’s spectrum of “indigo alternatives” compared with “true indigo” (right).  Internet color authority Piktochart lists indigo being associated with a variety of strong, evocative qualities including calm, serenity, trust, stability and mystery, adding that in some cultures it’s vested with symbolic meaning: In India there is historical significance derived from its use in traditional dyeing practices while in Japan, it’s linked with protection and healing.

#2b0082: A darker shade of indigo, providing a deeper, more intense version suitable for creating a dramatic effect. It evokes feelings of mystery and sophistication.

#350082: Slightly lighter than #2b0082, this shade offers a balance between deep and medium-dark, making it versatile for various design needs. It conveys a sense of depth and richness.

#400082: A medium-dark shade that maintains the richness of indigo while being slightly less intense. It balances intensity and calmness, evoking stability and reliability.

#560082: A medium shade that is vibrant and maintains the essence of Indigo. This shade can evoke feelings of creativity and inspiration.

#610082: A medium-light shade that is softer and can be used for a more subtle effect. It evokes feelings of calmness and relaxation.

#6c0082: A lighter shade that is still recognizable as indigo but offers a softer, more approachable feel. It evokes feelings of tranquility and peace.

Pre 900: From the Middle English, from the Old English cunnan (to know, know how) and cognate with the German & Gothic kann (know), the Old Norse kunna, Old High German kunnan, the Latin cognōscere (to know) and the Sanskrit jānāti (he knows).  The use to describe the receptacle emerged some decades later and was from the Middle English canne, can & cane, from the Old English canne and cognate with the German Kanne, the Old Norse and Old High German kanna, the Irish gann and the Swedish kana, all of which may be of West Germanic origin.  In the Late Latin, a canna was a “small drinking vessel”.  Can is a verb & noun, canned & canning are verbs; the noun plural is cans.

In Singlish, “can” is a versatile word.  Singlish (the construct a portmanteau of Sin(gapore) + (Eng)lish)) is still known by some language specialists as Colloquial Singaporean English but the blend is a more popular description and aligns the variation with flavors like Spanglish (Spanish influenced English), Hinglish (Hindi influenced English) & Konglish (Korean influenced English).  In Singapore, Singlish is used in parallel with Singaporean Standard English (differing usually from British English only in the accents although standards in the Far East tend generally to be higher) and it’s been documented since the 1960s although the linguistic tradition is much older.  In Singlish, the meaning of “can” can vary according to the relationship between the speakers and the tone of voice used although essentially it means “yes”, the nuances learned through use. For example Can or not? means “Can you do this?” to which the reply is Can (yes).  As a politeness, that might be responded to by Can meh? (Are you sure?), the expected answer being Can lah! (Yes of course!).  Inevitably, that begat Cannot lah!

In idiomatic use, a “can of worms” is a complicated, difficult, distasteful problem and if applied in retrospect it’s often of something which proved insoluble.  To “carry the can” is to take responsibility for something (particularly if challenging or troublesome); when used in the form “left carrying the can” it implies the task has been “dumped on one”, all others having evaded task.  It’s believed “carry the can” has its origin in the undesirable task of “latrine duty” in the military which required one literally to carry away from the temporary latrines “cans of shit” (also the origin of “can” as a slang word for “toilet”.  To “kick the can down the road” is delay dealing with a problem, the idea being of not then picking up the can as one eventually must.  “In the can” indicates something is complete, arranged, agreed or finalized and was from film production, the cores or reels of processed and edited films being stored “in the can” (a shallow, cylindrical (usually aluminum, cardboard or plastic) container made in various sizes to suit different film stocks.  To be a “can do” sort of person is to be dynamic, positive and anxious to accept a challenge.  The politician Campbell Newman (b 1963; premier of the Australian state of Queensland 2012-2015) described himself as “Can do Campbell” and enjoyed a fine election victory but it ended badly; in the next he suffered one of the bigger landslides in modern political history losing even his own seat.  “Canned laughter” was the process by which “laughter tracks” were spliced into the recordings of television comedies for subsequent broadcast, emulating a live (and appreciative) audience.  It’s often been regarded cynically but all the research suggests it really did work.  The popular phrase ”no can do” indicates an inability or unwillingness to do something.

Yes we can

Barack Obama (b 1961; US president 2009-2017) more than once observed he thought the speeches he wrote were better than any which came from his speechwriters and one can see his point but one of the reasons his presidency is regarded as insubstantial is that his words were more impressive than his deeds.  He was elected president and awarded the Nobel Prize for the same reason: He wasn’t George W Bush (George XLIII, b 1946; US president 2001-2009).  He promised much, exemplified by the phrase “…yes, we can” which expertly he worked into a speech he delivered in Nashua, New Hampshire on 8 January 2008, during the Democratic primaries while campaigning against crooked Hillary Clinton (b 1947; US secretary of state 2009-2013) for the party’s nomination:

…and tonight, I think about all that she's seen throughout her century in America — the heartache and the hope; the struggle and the progress; the times we were told that we can't and the people who pressed on with that American creed: Yes, we can.

At a time when women's voices were silenced and their hopes dismissed, she lived to see them stand up and speak out and reach for the ballot. Yes, we can.

When there was despair in the Dust Bowl and depression across the land, she saw a nation conquer fear itself with a New Deal, new jobs and a new sense of common purpose. Yes, we can.

When the bombs fell on our harbor and tyranny threatened the world, she was there to witness a generation rise to greatness and a democracy was saved. Yes, we can.

She was there for the buses in Montgomery, the hoses in Birmingham, a bridge in Selma and a preacher from Atlanta who told a people that "We Shall Overcome." Yes, we can.

A man touched down on the moon, a wall came down in Berlin, a world was connected by our own science and imagination. And this year, in this election, she touched her finger to a screen and cast her vote, because after 106 years in America, through the best of times and the darkest of hours, she knows how America can change. Yes, we can.

America, we have come so far. We have seen so much. But there is so much more to do. So tonight, let us ask ourselves: If our children should live to see the next century; if my daughters should be so lucky to live as long as Ann Nixon Cooper, what change will they see? What progress will we have made?

This is our chance to answer that call. This is our moment. This is our time — to put our people back to work and open doors of opportunity for our kids; to restore prosperity and promote the cause of peace; to reclaim the American Dream and reaffirm that fundamental truth that out of many, we are one; that while we breathe, we hope, and where we are met with cynicism, and doubt, and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of a people: Yes, we can.

As a rhetorical device, the repetition of “yes we can” worked well and he deserves credit also for the skill with which it was delivered; few US politicians since Ronald Reagan (1911-2004, US president 1981-1989) have shown such a flair for timing and effect and Reagan had the advantage of decades of practice under the tutelage of some of the best film directors.  But in office, reality bit and Obama soon understood why so many of his predecessors had commented that one surprise as president was how difficult it was to get anything done and the more that involved change, the harder it was.  On the night, “yes we can” thrilled many but among Republicans and even some factions in his own party, the spirit was somewhere between “no we probably shouldn’t” and “no we won’t”.  Still, he may have convinced himself because in his farewell address in Chicago in January 2017 he reprised “yes we can” before pausing for effect and adding “…yes we did”.  Dutifully, the audience applauded.

In the matter of can & may.

"Can" and "may" are modal verbs and the grammar Nazis police their use with some relish and for those who care about such things, there are frequent instances of misuse.  Can & may are sometimes interchangeable: just about anywhere on the planet it can at some time rain but it’s as correct to say it may at some time rain.  In some cases too, neither can nor may might be the appropriate word to use even if both are grammatically correct:  It’s really not helpful to ask: “Can I believe anything said by crooked Hillary Clinton?” or “May I believe anything said by crooked Hillary Clinton?” because the better choice is “Should I believe anything said by crooked Hillary Clinton?”  The answer is of course: “No”.  Still, the general principle is “can” is used of possibilities and “may” of permissions”, illustrated by the companion sentences “I can swim” & “May I go swimming”.  One of the quirks of English which may account for some the undue popularity of “can” is that while can’t has since the eighteen century been one of the language’s most commonly used contractions, “mayn’t is listed by most authorities as rare or archaic (though extinct might more reflect reality).  That was probably because can’t more effortlessly rolls from the tongue.

Campbell's Soup Cans (1962), acrylic with metallic enamel paint on canvas by Andy Warhol (1928–1987).

One of the landmarks of pop-art, Warhol’s Campbell's Soup Cans (1962), is a piece which depends for its effect, not on its content but its intent and there was a randomness of chance in the choice of subject.  The artist explained it by revealing for some twenty years he’d been having a can of the stuff for his lunch, thereby accounting for the motif of “the same thing over and over again”, a idea he’d reprise with variations for the rest of his life.  Had his habit been to enjoy sardines for lunch instead, the painting would have looked different but the meaning would not have changed.  It’s was also an coincidence of capitalism that 32 cans appear, that happening because at the time the company offered that many flavors but had they offered 36, the work would have contained that many.  Presumably, had the range been 29, 31 or some other number symmetrically more challenging things might have differed in detail but the concept would have survived.  Repeating the nearly identical image, the canvases stress the uniformity and ubiquity of the product’s packaging and subvert the idea of painting as a medium of invention and originality.  Although pop-art had at the time a newness about it, Campbell's Soup Cans was another step in the path art had taken since 1917 when Marcel Duchamp (1887–1968) had submitted a porcelain urinal for display in an art gallery, his purpose being to have people question whether art was defined by what it was or the context in which it appeared.  Does anything become art if it's put in an art gallery?  It was an confronting question and we’ve been living with its implications since, none more so than Ted Cruz (b 1970; US senator (Republican-Texas) since 2013), cans of "Campbell's Big'n Chunky Soup" his favorite food.  In 2016 he told US Weekly: "When I'm away from the family, in Washington DC, my dinner is a can of soup.  I have dozens in the pantry" and in that count he may be being untypically modest; his wife revealed that after their honeymoon, he returned from a trip to the grocery store with (literally) 100 cans. 

Campbell's Soup (Limited Editions).

On several occasions, the Campbell brand has taken advantage of the famous association and produced editions of soup cans with Warhol style labels complete with the artist's printed signature.  The first two runs used color schemes close to those which appeared in the 1962 work but the most recent was rather more garish with some changes to the layout.  A notable difference was the customers weren’t required to purchase 32, the cans sold individually.  In a development which Warhol would doubtless have applauded, the cans soon appeared on sites like eBay for three figure US$ sums, a healthy appreciation for their original RRP between US$1-2.
