How Language Connects Mind, World, and Reality


The Chinese characters for not only ‘meaning’ but for ‘connotation, denotation, import, gist, substance, significance, signification, implication, suggestion, consequence, worth, nuance, association, subtext, sense’  and more!

Posted by Keith Tidman

‘The limits of my language mean the limits of my world’, observed the Austrian-British philosopher Ludwig Wittgenstein in his 1922 book Tractatus Logico-Philosophicus. To that point, we might ask: How does language relate to the world? And, more particularly, does language shape human experience — our shared reality and our individual reality? Built into these questions is another — about how language connects mind and world, and in doing so arbitrates our experience of what’s around us.

At a fundamental level, words and ideas describe the world through things (people, horses, pomegranates), properties (purple, octagon, scratchy surface), relations (the moon is 384,000 kilometres from Earth, the flu virus infects millions of people globally, the calamari sits on her mezze plate), and abstractions (thought, value, meaning, belief). That is, language serves to create and aggregate knowledge, understanding, and experience. That’s broadly how we know what we know about reality. But language — the sounds made as people talk and the inscriptions made as they write — is more than just, say, a meta-tool for informational exchanges.

That is, people issue commands, share jokes, welcome visitors, pledge allegiances, pose questions, admonish, lie, explain feelings, threaten, share stories, exaggerate, sing, and so on. Body language (a suddenly raised eyebrow, perhaps) and tone (gruffness or ecstasy, perhaps) add an important layer. An observation by Willard Van Orman Quine, the 20th-century American philosopher, that ‘Language is a social art’, rightly captures this function of language in our lives. There’s a complex harmonising between what we infer and internalize about purported reality and the various kinds of things, properties, and relations that actually exist.

Language thus shapes our thoughts and changes how we think. The relation between thought (mind) and language is synergistic — that is, the combined effect of language and thought is greater than their separate effects. In this manner, a Chickasaw speaker, a Tagalog speaker, an Urdu speaker, a Russian speaker, and an English speaker perceive reality differently — the fundamental building blocks of which are words. As the British philosopher J.L. Austin noted:
‘Going back into the history of a word . . . we come back pretty commonly to pictures or models of how things happen or are done’.
The tie, we might say, between language and perceptions (‘pictures’ and ‘models’) — both concrete and abstract — of how reality, in all its nuance and complexity, plays out.

Correspondingly, the many subtle differences across the world’s roughly 7,000 languages — across vocabularies and other linguistic elements — frame and constrain the way we experience the world. That is, languages differ enough to lead to singularly dissimilar views of reality. Word choice, meaning (both denotation and connotation), syntax, metaphors, grammar, gender, figures of speech, correlation and causality, intent and expectation, and context all influence our perception of the world.

It is thus understandable, amidst this mix of languages’ ingredients, for the German-American philosopher Rudolf Carnap, writing in the mid-20th century,  to have counseled, ‘Let us . . . be tolerant in permitting linguistic forms’. Whether despite or because of this mix, language directly influences culture, which in turn bears on how we talk and what we talk about. Cultural norms influence this process. Yet, notwithstanding the power of perceptions, there is a world independent of language — empirically knowable — even if external reality may not be independent of observation and measurement. Galaxies and microbes exist.

As one illustration where language intervenes upon reality, it has been pointed out that the Native American language Nootka has actions as its principal classification of words. Emphasis is on verbs that describe reality not as physical objects (where subjects act upon objects) but as transitory occurrences — like ‘a meal occurs’ — or longer lived — like ‘shelter occurs’. The result ‘delineates’ the Nootka notion of reality, distinguishing it from others’. It is in the context of this rather expansive view of language that Noam Chomsky, the American linguist, is surely right in saying:
‘A language is not just words. It’s a culture, a tradition, a unification of a community, a whole history that creates what a community is. It’s all embodied in a language’.
Extending this theme, of tying together usage and perspective, in some languages there is no front, back, left, and right; instead, there is north, south, east, or west of something — a geographical kind of view of place. Two languages with just such a sense of location and cardinal direction are Guugu Yimithirr, which is an aboriginal language from Australia, and Sambali, spoken in a province of the Philippines. Another example entails agency for an accidental action: ‘Sebastian, the lead lab scientist, dropped the test tube’ (agency pinpointed, as in English) versus ‘The test tube dropped’ (agency hidden, as in Japanese). These rich differences among languages have implications that ripple across society, affecting, for example, values, norms, law, economics, and political policy.

We might argue that the plasticity of language — and the consequential differences in how language, over time, shapes our understanding of reality — affects how the mind distinguishes between fact and fiction. This observation hints at the subjectivity associated with postmodernism in defining the truth and falsity of perceived reality — at least in a linguistic context. In this view, a subjectively conscious reality — differing among the native speakers of diverse languages — and the external world do not intersect, or if they do, it is but imperfectly.

As such, purported knowledge, understanding, and belief are likely to be contested among partisan cultures, each embracing its own conventions regarding how the mind might describe the world. Writing in the mid-20th century, Algerian-French philosopher Jacques Derrida pointed to this issue of defensively shielding one’s own language, saying:
‘No one gets angry at . . . someone who speaks a foreign language, but rather with someone who tampers with your own language’.
And yet, with Derrida’s cautionary words in mind, whose truth and falsity is it? And whose perspective is valid, or at least the most valid (that is, the least flawed)? Does it come down to simply a catalogue of rules for usage prescribed within each community speaking and writing a particular language? Perhaps J.L. Austin got it right in opining, ‘Sentences are not as such either true or false’.

Perhaps, too, it is as Humpty Dumpty famously declared in Lewis Carroll’s book, Through the Looking Glass, when he said:
 ‘When I use a word,  it means just what I choose it to mean, neither more nor less’.
That’s not too far off from the latest thinking about language, actually. Why so? It’s not only that different languages seem to lead to a different knowledge, understanding, and experience of reality within the mind. Rather, the effects of language seem more granular than that: Users within each of the world’s thousands of languages have different understanding of reality than even their fellow native speakers of those languages.

There are thus two levels of reality in the mind’s eye: one based on shared languages, such as NorwegianKhmer, and Maori. And one based on individuals within each language group whose personalised understanding and application of language uniquely and subtly differs from one person to another — quite apart from the differences in how, as individuals, we stamp our customs and norms on language.

Butter Nonsense


Posted by Martin Cohen


Last week saw President Trump throwing out a CNN reporter from the White House Press Pool for disagreeing with him about ‘the facts’.

CNN called it an attack on press freedom, but the collective response from other journalists has been muted. And no wonder, because these days the press are themselves heavily into ‘denying’ certain views. We've all heard about ‘Climate deniers’ and how evil they are, but this last month saw a vehement attack on Cholesterol deniers!

Sarah Boseley, longtime health editor of the supposedly liberal UK newspaper, The Guardian, launched the attack with a piece called:

Butter nonsense: the rise of the cholesterol deniers

The stand-first sums up the piece accurately:
‘A group of scientists has been challenging everything we know about cholesterol, saying we should eat fat and stop taking statins. This is not just bad science – it will cost lives, say experts’.
The back story is that The Guardian, has long been very chummy to the pharmaceutical industry and regularly promotes the case for expensive drugs and mocks campaigners. Its longtime medical writer, Ben Goldacre, under the heading we just saw reused by Ms Bosely of ‘bad science’, regularly wrote in favour of Big Pharma and against alternative medicine let alone common-sense approaches without ever declaring his own links. There were family links as well as a career one via the Institute of Psychiatry to many of the industries favoured by the arguments in his articles.

‘Big Phama’, firms like Unilever; SmithKline Beecham and Pfizer Limited (two producers of antidepressant drugs); Novartis Pharmaceuticals (previously Ceiba Geigy); Lilly Industries Ltd (the manufacturers of Prozac); Hoescht Marion Roussell; GlaxoSmithKline (vaccine manufacturers) … and so on smiled on his work. Goldacre even received an award for ‘science journalism’ in 2003 - the award that year being sponsored by GlaxoSmithKline.

It’s enough to make you cynical, as is the fact that in the early years of 2000, the Institute of Psychiatry held over 200 research grants with an annual value of around £14.5 million. Its second highest source of funding was the pharmaceutical industry. The Institute is part of King’s College London, and part of the UK’s public education system. Yet for all the money the public devotes to universities, and for all the special status of university academics, private money like this drives research findings.

But back to butter, and the new money-spinner today is prescribing drugs called statins in order to reduce cholesterol. Justin Smith estimated in a piece for Statin Nation that the market for these drugs was more than $19 billion and rising. In The Guardian piece, Boseley says ‘statins are out of patent and therefore no longer make money for the companies that originally put them on the market’.

Note those ‘weasel words’, ‘for the companies that originally put them on the market’.

I looked at the cholesterol debate - I could hardly NOT do - in my food book published this month *. It is (chemically speaking) a very 'complex' area (all diet things seem to be when you get into them), but there are some studies that can be talked about in a broader sense, including several iconic long-term studies of low-cholesterol diets which do seem to demonstrate:
(a) that it is effectively impossible to isolate one factor in a dietary study, (alteration of one factor disguises changes in other factors too) and

(b) in as much as it is possible, not only that there is no evidence to support the 'low cholesterol diet' approach, there are indications that it might actually increase the risk of heart disease!
The Guardian piece makes little attempt to present a 'debate' but instead pushes the view that there is an argument for refusing to give cholesterol-deniers a platform, just as some will no longer debate with climate change sceptics. The position is summed up by one of Prof Rory Collins of Oxford University, a professor of epidemiology who says quite unashamedly that by cholesterol deniers he means people who dispute the claim that diets high in cholesterol are dangerous for heart health. As Sarah Boseley puts it here, these are people saying butter is safe and statins are dangerous. BAD PEOPLE!

No real evidence is actually offered in the piece, and when I asked Ms Boseley for any background studies she might have used, she did not respond to the request.

In fact, the available evidence is very different. One small study of Australian men found swapping from butter to margarine, for example, found the death rate from heart disease went up amongst the margarine eaters. Another study, in Denmark, that put people on a low-salt diet precisely to protect heart health, found that perversely it led to cholesterol levels shooting up!

Surveying the research, some 20 years ago now, Dr Laura Corr a cardiologist at Guys Hospital in London concluded that :

‘The commonly-held belief that the best diet for prevention of coronary heart disease is a low saturated fat, low cholesterol diet is not supported by the available evidence from clinical trials"

However, seven years ago, an influential meta-analysis by the Cholesterol Treatment Trialists found that:
‘Observational studies show that there is a continuous positive relation between coronary disease risk and blood cholesterol concentrations [and] larger reductions in LDL cholesterol [the so-called 'bad cholesterol'] might well produce larger reductions in risk.’
In 2015, another systemic review by researchers from various international institutions in Japan, Sweden, UK, Ireland, US and Italy, published in the BMJ, insisted that - on the contrary! - as LDL cholesterol went down, all-cause mortality went up while higher levels of ‘bad ’ were apparently linked to living longer.

Don’t ask for new studies, as there have been so many, and yet analysis of what they prove remains completely partisan. It has been noted that the actual trial data held by the Cholesterol Treatment Trialists’ Collaboration on behalf of the industry sponsor has not been made available to other researchers, despite multiple requests over many years.

Since then, rather than demonstrate their case through persuasive research, advocates of the low-fat, low-cholesterol diets have sought to shut-down debate even trailing that new term cholesterol deniers...

After reading all the evidence, my feeling is that cholesterol levels are not simple, one dimensional values to be turned up or down like a thermostat and attempts to shoehorn it into a Manichean (good / evil) view of dietary factors risks actually harming human health. Attempts by governments and media to rule definitively on it are unwise and a distraction from practical steps that can be taken.

PP #40 The Noble Savage












'Because things don’t appear to be the known thing; they aren’t what they seemed to be neither will they become what they might appear to become.'

Posted by Thomas Scarborough



Paul Gauguin (1848-1903) -- a painter whose legacy is not only disputed today, but increasingly disputed.  An interesting feature of Gauguin's paintings in his 'Pacific phase' was their great beauty on the surface of it, while in the background lurked death, suffering, and cruelty.

In seminary, they taught us like this: Gauguin travelled to Tahiti, hoping to find untrammelled freedom in the ideal of the 'noble savage', but instead he discovered death, suffering, and cruelty.  Therefore it was a false ideal.

The photo reminds me of the art of Paul Gauguin.  I am the boy on the left -- in my own 'Pacific phase' in childhood.  On the surface of it, the photo shows healthy, happy people.  But as in the art of Gauguin, a deformed man crouches in their midst.  I was fearful of him then.

Yet he was in the photo because he was included.  He was loved.  He was cared for.  Is this what Gauguin saw?  Did his fascination with the 'dark side' originate, not in his disillusionment with the ideal, but in the strange goodness of the 'noble savage'?
