Delaying Dementia

This article from Canadian Press struck a nerve. Not being au fait with the recent clinical literature on the subject of Alzheimer’s I was interested to read that there is a correlation between the formally educated mind and the onset of dementia. As a child of a dementia sufferer (a mother - cultured and refined but not educated) I have long felt compelled to maintain an intellectually active mind to stave off dementia – this notion wasn’t based upon any clinical evidence, merely a homespun psychological analog of keeping fit. It appears that once dementia sets in the “trained” mind, the condition spreads much quicker than the “untrained” mind - perhaps because the neural network is so highly developed?

Educated people develop dementia later in life, but decline quicker: study

TORONTO – It’s been known for years that people with higher education levels tend to develop Alzheimer’s disease later in life than those with less formal schooling. But a new study suggests that once the symptoms begin, people with more classroom time go cognitively downhill at a faster rate.

In fact, said lead researcher Charles Hall, the study showed that someone with 16 years of formal education would experience a rate of memory decline that is 50 per cent more rapid than someone with just four years of schooling.

“People with more education experience a delay in the actual decline in memory that is characteristic of people who are developing dementia, in particular Alzheimer’s disease,” said Hall, a biostatistician at the Albert Einstein College of Medicine.

“However, once that decline begins, it proceeds more rapidly and by the time people are actually diagnosed, they’re about at the same place” as less-educated people diagnosed earlier, Hall said Monday from New York.

Scientists believe that better-educated people build up a “neuronal reserve or compensational ability.” Although the physical characteristics of Alzheimer’s likely develop in the brains of both well-educated and less-educated people at a similar rate, those with more education don’t begin showing symptoms until later in the progression of the disease because of this neuronal reserve, he said.

To illustrate the point, Hall cited the case of one research participant – a science professor – who died of cancer during the study period.

The man showed some decline on neurological tests but no decline in handling daily activities, and the researchers assumed his slight cognitive impairment resulted from chemotherapy.

“And we were stunned when the neuropathologist reported a significant pathology of Alzheimer’s (in the man’s autopsied brain),” he said. “It is not something that any of us would have guessed clinically.”

The study, published in Tuesday’s issue of the journal Neurology, involved 488 seniors who were followed over time, including 117 who developed dementia. All participants, who were born between 1894 and 1908, were physically and mentally healthy when enrolment for the study began in 1980.

Hall said researchers followed participants for an average of six years using annual cognitive tests. Levels of education ranged from less than three years of elementary school to postgraduate degree work.

The study found that for each additional year of formal education, memory decline associated with oncoming dementia was delayed by approximately 2 1/2 months. But once that accelerated deterioration began, more highly educated subjects experienced a cognitive downturn that occurred four per cent faster for each additional year of education.

For example, a university graduate with 16 years’ education and diagnosed at age 85 would have begun to experience accelerated memory loss 3.8 years earlier, at age 81. But a person with just four years of schooling, diagnosed at the same age, would have begun to experience a less rapid rate of decline around age 79, 6.3 years before diagnosis, the study shows.

Hall said because the subjects were born at a time when educational opportunities differed markedly from more modern schooling, it’s difficult to predict how the findings would apply to subsequent generations.

“Whether that (would) apply to people who were born in the 1920s or the 1950s who had different life experiences is not known,” he said. “Although I don’t know any reason why it would not hold, I haven’t proven it.”

Hall said people shouldn’t misinterpret the results and believe that having more education has little benefit against the ravages of dementia in the long run.

“I would not say that it’s bad to get more education,” he said. “It certainly does not cause the disease process (itself) to speed up, and given the opportunity of an extra year or two of symptom-free life, I would definitively take it.”

Neuropsychologist Dr. Mary Tierney, director of the Geriatric Research Unit at Sunnybrook Health Sciences Centre in Toronto, called the findings “quite important and valid, absolutely.”

“People who are involved in intellectual activity, problem-solving, they’re just generally intellectually stimulated,” said Tierney, who was not involved in the study. “So those people, when they start developing the . . . neuronal loss that we find in Alzheimer’s, they can compensate more . . . they look better and they perform better in the environment.”

And it may not be just formal education in one’s early years that promotes cognitive health: there is some suggestion that flexing mental muscles even later in life with puzzles, reading, socializing – and even video games – may help stave off the onset of dementia.

For those without a lot of education, Tierney said “possibly now it’s time to compensate . . . Attempt to read more, socialize more, again avoiding the negative lifestyle of the couch potato.”

“We don’t know if it’s going to make a big difference if we get involved in all these activities later (in life),” she said. “But we know it can’t hurt. So it’s probably better to do it.”

Brights or the “New” Atheism

Atheism is big publishing business these days. The rash of recent bestsellers has been dubbed the “New” Atheism – and the loose coalition of those who subsribe to the naturalism promoted across these books - as Brights. I want to make four points:

1. I resent the haughtiness of the term “bright”. The term fails to capture many who are not out of sympathy with the naturalistic project: I, for one, would prefer to be called an Epicurean, skeptic or humanist, terms that have immeasurably richer connotations. Dante had long since had a place reserved for us Epicureans in his sixth circle of hell.

2. The so-called “New” Atheism has a ring of inauthenticity to it when viewed against a prevailing socio-cultural climate of feigned indignation and cultivated notoriety.

3. There is already an abundance of hardheaded discussion on the nature of religious belief – John Mackie and Keith Yandell,  Michael Martin and Kai Nielsen - all atheists that have for the most part been completely overlooked by the both authors and commentators. Better yet, try reading Hume and Lichtenberg.

4. Last but by no means least, a deep point is lost within the discussion. Whatever the failings of “Intelligent Design” theory, it marks a broader philosophical question: that is, whether science is explanatorily closed, whether the ultimate explanations provided by science are in need of supplementation. There are those in consciousness studies who take the view that science is in need of supplementation to solve the mind-body problem.

Publishing Hyperbole

I for one am very pleased that consciousness has become a topic for discussion amongst the literati. I welcome the accessible writing of David Armstrong, Susan Blackmore, Andy Clark, Tim Crane, Dan Dennett, Gerald Edelman and Stephen Pinker to name but a few of the more prominent popular expositors. But I cringe at the dreadful  hyperbole that publisher’s insist on generating. A case in point is Random House’s blurb on the forthcoming book by Jeff Warren entitled The Head Trip: Adventures on the Wheel of Consciousness.  Here is the offending excerpt:

Part user’s manual and part travel guide, The Head Trip is an instant classic, a brilliant summation of consciousness studies that is also a practical guide to enhancing creativity, mental health, and the experience of what it means to be human. Many books claim that they will change you. This one gives you the tools to change yourself.

Wow – an instant classic, eh? Move over Dave Chalmers! :) The ultimate “how to” book” - a staple of tabloid TV – it promises that the reader’s humanity might also be enhanced. Rollover Shakespeare and tell Goethe and Kafka the news.

Whatever the virtues of Warren’s book may be, this sort of pompous promotion is annoying. Not to mention the “hip” title and an annoying subtitle. To be fair this rash of subtitling books is as much a part of the academic industry (it may well have begun here) as it is a part of the popular publishing industry. These pseudo literary titles are no more than a crass marketing ploy to “sex-up” the product. I liken these subtitles to the blurb in an art exhibition catalogue “telling me what the painting is really about”. This is pure condescendence: a general reader is ostensibly already interested in the inherent complexities of the subject matter.

Encounters with Michael Oakeshott

Here is another finely crafted essay on Oakeshott, the man – written by someone who knew him well and who through his editoral activities, did much to bring Oakeshott to wider attention.  This essay should be read along with Michael Oakeshott as a Character and Why Read Oakeshott?  

 ========================================

By Timothy Fuller

My first encounter with Michael Oakeshott was on a Saturday afternoon in the library of Kenyon College in the fall of 1959 when, with the place mostly all to myself, I found on a shelf the Blackwell’s Political Texts edition of Hobbes’s Leviathan, edited by a certain Michael Oakeshott. I was just then deciding to change my major field of study – I had started as a pre-med, then considered Classics and English. I was taking my first course in political philosophy, a subject which immediately attracted me. Finding Oakeshott’s Leviathan confirmed my intuition. I was about to write an essay on Hobbes for the course. I sat down at a secluded library table to look through what this author, hitherto unknown to me, had to say. From the first sentence, “Thomas Hobbes, the second son of an otherwise undistinguished vicar…” I was captivated. I read through the whole essay as the afternoon wore on. I was taken by what I later learned was a famous and controversial interpretation among Hobbes scholars. As I finished it, I looked up and thought to myself that I must someday write an essay like this, that to desire anything less was not to be serious about what I now knew I intended to do.

The following Monday I burst in on my political theory professor asking if he had ever heard of Oakeshott. Providentially, one might say, he also was an Englishman who had read modern history at Trinity College, Cambridge before coming to America to do graduate work at Harvard and to teach. Not only had he known Oakeshott but he had worked with him on the Cambridge Journal in the 1940s. He was the first of those I was to encounter who described what it was like in the 1930s and 40s to hear the legendary Oakeshott lecture on the history of political thought (others I met later include Brian Tierney and Peter Laslett). My teacher was patient with my enthusiasm to take up political thought and teach it. It is, of course, what I did and do, and I have never regretted it for a moment. I owe my direction, in part, to the Oakeshott I was to meet face to face only much later.

He was legendary among Cambridge students, not alone for his lectures but also for somewhat dandyish ways and for his love of horse racing. He was said to have abandoned his scheduled lectures on certain occasions when the races at Newmarket were on. The latter interest found expression in the book he wrote with his friend, Guy Griffith, A Guide to the Classics or How to Pick a Derby Winner. The book was published in 1936 by the distinguished house of Faber and Faber, whose esteemed editor was T. S. Eliot. At least a few people, looking hastily at the title, must have bought it thinking it was an essay by two scholars on the classics. Eliot mentions the book in passing in his 1944 address to the Vergil Society, “What Is a Classic?” Careful readers used its prescriptions for betting with occasional success and, so I am told, one such sent Oakeshott, in appreciation, a case of Chateau Margaux.

Oakeshott lurked in the back of my mind for a few years until, while I was in graduate school, Rationalism in Politics appeared. This was the book that launched him in America and remains today his most widely read book. At this point, my interest was rekindled and, when I came to writing my doctoral thesis on John Stuart Mill, I deployed numerous ideas of Oakeshott’s in examining and criticizing Mill’s basic political doctrines. In part, also, I was responding to the very controversial view of Mill that Maurice Cowling – at that time, a follower of Oakeshott – had recently published in his Mill and Liberalism to the effect that Mill was a “moral totalitarian.” This accusation is not one Oakeshott himself would have pronounced. In 1979, through Shirley Letwin, I finally met and began a rewarding friendship with Cowling who, by then, had overturned a number of his earlier Oakeshottian views and who, characteristically as I came to know, rebuffed my praise of his early work. When I started teaching, Oakeshott’s work became a regular part of my courses on modern political thought.

My first meeting with Oakeshott came in 1974, the centennial year of Colorado College. (He was to return once more, in June 1982, to receive an honorary degree) I had proposed, and the college had put me in charge of, organizing a year long lecture series on the present and future state of liberal learning. I wrote to Oakeshott, inviting him to spend a week at the college and to present the first lecture. He accepted, and offered, in Tutt Library at Colorado College on September 17, 1974, to an audience of nearly four hundred, “A Place of Learning.” This now well-known essay was printed in the Colorado College Studies in January 1975, later reprinted numerous times in various places, ultimately to appear as the lead essay in The Voice of Liberal Learning (1989).

Oakeshott electrified the audience with extraordinarily powerful, and beautifully conceived, formulations issuing from the mouth of a slight, unassuming man who might go unnoticed unless and until he spoke with you. Oakeshott was, of course, highly critical of the contemporary social sciences but he made his points with a grace that led one of my colleagues in sociology to remark that he had never been so charmingly demolished. At the same time, his evocation of what liberal learning really is was so heartfelt, and expressed with such an effortless invocation of the great resources of the Western tradition, that he instantiated and made real to all present what, in lesser hands, would have seemed hopelessly romantic. Apart from his lecture, he spent much of his week in residence talking with students and faculty and I began to glimpse his greatness as a teacher. Later, when I witnessed Oakeshott performing in the general seminar of the History of Political Thought at LSE, I enjoyed another version of the same experience.

His visit to Colorado was the beginning of our friendship which lasted until his death in December 1990. I took him around Colorado to admire the skill of cowboys on horseback punching cows, to see the aspen groves turning to orange and gold, and to clamber about the hills of the Cripple Creek goldfields. I asked him why he had agreed to come to Colorado since, although my letter had made it clear that I knew something about him, he surely had never heard of me. This was not quite true because we had several mutual acquaintances who had vouched for me, as I later found out.

He told me that two things determined him to come: First, he had an uncle who had migrated to California at the turn of the century to grow tomatoes; this had excited in him an interest in the American West and he read widely on the topic from childhood. He had a lot of western literature at his disposal. Although he had been to the east coast of the United States, this was his first chance to see the west of his boyhood imagination. It seemed to him exactly like what he had read about. Second, he was charmed by the thought of an encampment of liberal learning nestled at the foot of Pike’s Peak which, as he imagined it, had been founded by pioneers crossing the great plains in covered wagons bearing Shakespeare and the Bible. This was not quite accurate but not altogether wrong either. He endeared himself to us all when he began his now famous lecture by saying: “I have crossed half the world to find myself in familiar surroundings: a place of learning.” We felt – and he felt – genuine kinship between ancient Cambridge and pioneering Colorado College. This quintessential Englishman had a romantic attraction to the “frontier experience.”

We corresponded, and then in 1977 I began my annual pilgrimages to England to spend time with him. We arrived in London in August of that year and Oakeshott took us for a drink to the bar of the Ritz Hotel (introducing me to one of his favorite drinks, Campari and soda) before going along to lunch with Shirley and Bill Letwin at 3 Kent Terrace which was to result in another extraordinary friendship and my entry into the most rewarding society of friends and companions I have known. Meeting Shirley Letwin for the first time could be a test of one’s poise. If you got through the test satisfactorily, you could bank on a permanent commitment that taught me what fierce and devoted friendship really means. I did not yet know that, of course. Michael had alerted her about me and had shown her a seminar paper I had written about his thought. She started by telling me it was among the best things she had seen on Michael, but then went on to pummel me with questions about all the American political theorists whom she seemed to despise, many of whom were friends of mine. I managed to maintain myself until Michael, in his marvelously graceful way, turned the engagement to a more conversational topic. I owe to Michael the chance of such high, Aristotelian friendship with Bill and Shirley Letwin.

In 1979, I arrived at LSE to spend time as an Academic Visitor in the Government Department. Oakeshott had long since formally retired but he retained his room in Lincoln’s Chambers and, as he only came to the School officially on Tuesdays for the History of Political Thought seminar, I was given the other desk in his room that had been before me that of Professor Pickles. On Tuesdays when he was to give his papers on the study of history, which were later published in On History and other essays (1983, 2000), he would spend the day at his desk rewriting the papers. He did this every time he presented them, refining them over a number of years before they finally were published. In the meantime, Xeroxes of various versions of them circulated among his devoted student followers. Unless he was to see a student, I remained in the office working back to back with him. He smoked continuously until it was time to leave our cloudy space for the seminar meeting at 4 PM. We often went out to eat together after the seminar, his two favorite places being Luigi’s on Tavistock Street and Mon Plaisir on Monmouth Street. The latter especially remains a favorite of mine. It was during this time that I came to know well Bill and Shirley Letwin, Ken Minogue, Elie Kedourie, Wolfgang Von Leyden, Maurice Cranston, Robert Orr, John Morrall and John Charvet, and also Maurice Cowling at Cambridge. I still think of this as a golden era at the LSE, a time when most of my best students came to study in the History of Political Thought program.

Oakeshott could enchant students even when, as was often true, they understood him only in part. He was, at eighty, more attuned to the young than teachers half his age. He never forgot what it was to be young, and he could forgive students for much because he loved the glorious, transitory inconsequence of youth. Like Socrates, he was young when old. He never imposed his ideas except so far as their natural force would take them. He would listen patiently to virtually any question students posed and would answer them by making them better questions than they started out to be. Study in the university, he famously said, is the gift of an interval: a liberation from the unavoidable drills of school and a momentary release before the limiting responsibilities of adulthood set in. He thought work should balance play, enjoyment ambition and conversation debate. He urged that we should be conservative with respect to the rules of the civil life in order to be radical in everything else. He was a Bohemian in the right way. He told students arriving at the university to think of themselves as strolling minstrels stopping off to perform before they were moved on by the local constabulary, and he encouraged them to think this far superior to occupying a niche in the social organization. He counseled students to be, as it were, irresponsible for a time so that liberal learning could enter in. And yet no one could doubt that what he was urging, and what he exemplified, was the profound seriousness of the life of the mind.

In the 1980s, Oakeshott decided to give up his flat at 16 New Row in Covent Garden to live year round in his Dorset cottage in the tiny village of Acton on the edge of the Purbeck marble quarries. His cottage was the combination of two quarryman’s cottages which he had bought years before, knocking out the central partition to make one larger cottage. I first visited the cottage in the summer of 1977. In the decade of the 80s I visited him often there. There was no central heat, and, until late in his life, no telephone or indeed other elements of that modern life for which Oakeshott had little regard. The computer did not exist for him. He thought most modern inventions had done the human race little good. He wrote everything by hand. From his cottage one looked out on the Channel to the Isle of Wight in the distance. And, because of its situation in the Wessex country of Hardy, one felt oneself transported back before World War I, even to the 19th century, to a world where one might meet Jude the Obscure coming down the path. This is exactly how Oakeshott wanted to feel. Life was, to him, sweeter then.

Oakeshott kept most of his books at the cottage, including many rare volumes that he was able to collect in the good old days when old books were relatively cheap and mostly bought by people who would read them rather than treat them as collectibles, antiques or investments. The cottage had, at one end of the main room, a large fireplace that gave off much heat, at least at that end of the room. I would often huddle at the fireplace while Oakeshott would roam the farther reaches of the room complaining that it was rather hot.

He was an excellent cook and gardener. One of his prized achievements was to have turned a deep cistern in his garden into a guest bedroom that one entered by climbing down a ladder about eight feet below ground where a bed awaited one. To me it seemed a little out of Edgar Allen Poe but I never had to sleep there; I always got the guest room inside the cottage. Oakeshott also owned a blue 1958 MG-B which he drove at excessive speeds through the hedgerows.

The cottage was a place of conversation that often lasted until late into the night. It was genuine conversation. It could be witty and frivolous, up to a point. It could be sophisticated and often philosophical. It could be literary or theological. It could be, but infrequently, about current politics for which Oakeshott had little taste even though he was well informed. If you posed a serious question to him, he would often sit entranced for a time, until you began to think he hadn’t heard you and you started to speak to fill in the void or to repeat yourself when, of a sudden, a considered, precise and elegant response would come forth, and you realized that, in such moments, elapsed time had no significance for him.

In his learned brilliance, Oakeshott made shrewd judgments about people and arguments, but he was, in a way, the least judgmental of all people. He was an intellectual aristocrat, but his sense of the universal predicament of being human – what he called the ordeal of consciousness – was authentically democratic. He was a true individualist, and I mean really and truly. He spent no time worrying whether others had more or less than himself, he treated every encounter with another person as a unique circumstance, a potentially poetic experience. On the other hand, if an encounter was not fruitful, he went his way happily, awaiting another opportunity to present itself. He had the capacity, like Montaigne and Pascal, to sit alone in a room, to think and to write. He was certainly a companion to himself and, perhaps for that reason, he was a marvelous companion to others. When he found himself talking with someone of modest talent and little thought, he would look up at a corner of a room, jangling the coins in his pocket, and respond, “Oh, you think that! Do you? Do you?” His “do yous” were famous. And, at the Oakeshott memorial meeting at LSE in 1991, John Casey, a fellow of Oakeshott’s Cambridge college, suggested that if God had spoken to Oakeshott rather than Moses, saying “I Am that I Am,” Oakeshott might have replied, “Are you? Are you?”

Oakeshott was a great teacher but he thought of himself as a learner, occasionally disclosing to others what he thought he had learned, inviting them to say what they might think of it. He was also a writer in the deepest sense. He wrote, so far as I can tell, every day of his life from his undergraduate days until well into his eighties. He kept notebooks in which he copied out quotations, analyzed what he was reading, tried various opening gambits for essays, and so on. As we all now know, he wrote numerous essays and lectures that he did not publish.

When he died he bequeathed his papers to Shirley Letwin to do with as she thought best. She and I went to the cottage in Dorset in May 1991 to remove the papers to the new Letwin house in London at 15 Arlington Road where, until not too long ago, they were kept before coming to the LSE. She and I worked together on the joint venture to publish some of these with the Yale University Press. Since most of this archive, with the exception of some private correspondence, is now accessible to all interested parties, I need say no more about it. I read all of it, but so can anyone else now. Rather, I want to remember him in terms of some of the most memorable things he had to say on the topics dearest to his heart.

Oakeshott was eloquent on youth, old age and mortality: “Everybody’s young days are a dream, a delightful insanity, a sweet solipsism … the world is a mirror in which we seek the reflection of our own desires … urgency is our criterion of importance; and we do not easily understand that what is humdrum need not be despicable. We are impatient of restraint; and we readily believe, like Shelley, that to have contracted a habit is to have failed … For most there is what Conrad called the ‘shadow line’ which, when we pass it, discloses a solid world of things … each with its price; a world of fact, not poetic image , in which what we have spent on one thing we cannot spend on another; a world inhabited by others besides ourselves who cannot be reduced to mere reflections of our own emotions.” (On Being Conservative, 1956)

He spoke of love and friendship as only one who has felt and considered both could do: “Friends and lovers are not concerned with what can be made out of each other, but only with the enjoyment of one another. A friend … is somebody who evokes interest, delight, unreasoning loyalty, and who (almost) engages contemplative imagination … Neither merit nor necessity has any part in the generation of love; its progenitors are chance and choice – chance, because what cannot be identified in advance cannot be sought; and in choice the inescapable practical component of desire makes itself felt.” (The Voice of Poetry in the Conversation of Mankind, 1959)

“In conversation,” he famously remarked, “thoughts of different species take wing and play round one another, responding to each other’s movements and provoking one another to fresh exertions … There is no symposiarch or arbiter; not even a doorkeeper to examine credentials … voices which speak in conversation do not compose a hierarchy… it is an unrehearsed intellectual adventure … with conversation as with gambling, its significance lies neither in winning nor in losing, but in wagering … It is the ability to participate in this conversation, and not the ability to reason cogently, to make discoveries about the world, or to contrive a better world, which distinguishes the human being from the animal and the civilized man from the barbarian.” Conversation is also the sign of liberal learning for “Education, properly speaking, is an initiation into the skill and partnership of this conversation.” (The Voice of Poetry)

Universities are places of learning ideally set aside to achieve conversationality: “A university will have ceased to exist when its learning has degenerated into what is now called research, when its teaching has become mere instruction and occupies the whole of an undergraduate’s time, and when those who come to be taught come, not in search of their intellectual fortune but with a vitality so unroused or so exhausted that they wish only to be provided with a serviceable moral and intellectual outfit; when they come with no understanding of the manners of conversation but desire only a qualification for earning a living or a certificate to let them in on the exploitation of the world.” (The Idea of a University, 1950)

Of course politics, the necessary evil, is always with us: “The pursuit of perfection as the crow flies is an activity both impious and unavoidable in human life. It involves the penalties of impiety (the anger of the gods and social isolation), and its reward is not that of achievement but that of having made the attempt. It is an activity, therefore, suitable for individuals, but not for societies.” (The Tower of Babel, 1948)

“In political activity, then, men sail a boundless and bottomless sea; there is neither harbour for shelter nor floor for anchorage, neither starting-place nor appointed destination. The enterprise is to keep afloat on an even keel; the sea is both friend and enemy; and the seamanship consists in using the resources of a traditional manner of behaviour in order to make a friend of every hostile occasion.” (Political Education, 1951)

His views on politics resulted from considering politics philosophically: “Thinking is at first associated with an extraneous desire for action, and it is some time, perhaps, before we discern that philosophy is without any direct bearing upon the practical conduct of life, and that it has never offered its true followers anything which could be mistaken for a gospel. Of course, some so-called philosophers afford pretext enough for this particular misunderstanding. Nearly always a philosopher hides a secret ambition, foreign to philosophy, and often it is that of a preacher. But we must learn not to follow the philosophers upon these holiday excursions.” (Experience and its Modes, 1933)

“Philosophical reflection is recognized here as the adventure of one who seeks to understand in other terms what he already understands … It is, in short, a well-considered intellectual adventure recollected in tranquility.” (On Human Conduct, 1975)

One can see how, in Oakeshott’s disposition, the distinct activities of philosophy and poetry – it is hard to say which he came to value more – nevertheless will converge: “Poetry has nothing to teach us about how to live or what we ought to approve. Practical activity is an endless battle for noble or for squalid but always for illusory ends, a struggle from which the practical self cannot escape and in which victory is impossible because desire can never be satisfied … Poetic activity has no part in this struggle and it has no power to control, to modify, or to terminate it. If it imitates the voice of practice its utterance is counterfeit. To listen to the voice of poetry is to enjoy, not a victory, but a momentary release, a brief enchantment … Poetry is a sort of truancy, a dream within the dream of life, a wild flower planted among our wheat.” (The Voice of Poetry)

Throughout, Oakeshott felt the pressure of the eternal on our temporality and he reflected on the resulting tension – the tension characterizing the civilization of which he was a loving voice – over the whole of his life: “Religious faith is the evocation of a sentiment (the love, the glory, or the honour of God, for example, or even a humble caritas), to be added to all others as the motive of all motives in terms of which the fugitive adventures of human conduct, without being released from their mortal and their moral conditions, are graced with an intimation of immortality: the sharpness of death and the deadliness of doing overcome, and the transitory sweetness of a mortal affection, the tumult of a grief and the passing beauty of a May morning recognized neither as merely evanescent adventures nor as emblems of better things to come, but as aventures, themselves encounters with eternity.” (On Human Conduct)

Cognitive Science meets Social Epistemology

Cognitive Science and FactCheck.org, or Why We (Still) Do What We Do

The following article is culled from Annenberg Fact Check (if this is the sort of discussion you find interesting, why not check out the journal EPISTEME. Articles such as Alvin Goldman on the epistemic failure of the FBI regarding 9/11 and Roger Koppl on why he thinks torture doesn’t generate epistemic veracity, intelligently speak to current issues of public interest).

October 17, 2007
by Joe Miller

Have you heard about how Al Gore claimed to have invented the Internet? What about how Iraq was responsible for the attacks on the World Trade Center? Or maybe the one about how George W. Bush has the lowest IQ of any U.S. president ever? Chances are pretty good that you might even believe one (or more) of these claims. And yet all three are false. At FactCheck.org our stock in trade is debunking these sorts of false or misleading political claims, so when the Washington Post told us that we might just be making things worse, it really made us stop and think.

A Sept. 4 article in the Post discussed several recent studies that all seemed to point to the same conclusion: Debunking myths can backfire because people tend to remember the myth but forget what the debunker said about it. As Hebrew University psychologist Ruth Mayo explained to the Post, “If you think 9/11 and Iraq, this is your association, this is what comes in your mind. Even if you say it is not true, you will eventually have this connection with Saddam Hussein and 9/11.” That leaves myth busters like us with a quandary: Could we, by exposing political malarkey, just be cementing it in voters’ minds? Are we contributing to the problem we hope to solve?

Possibly. Yet we think that what we do is still necessary. And we think the facts back us up.

The Post story wasn’t all that surprising to those who follow the findings of cognitive science research, which tells us much of our thinking happens just below the level of consciousness. The more times we hear two particular bits of information associated, for example, the more likely it is that we’ll recall those bits of information. This is how we learn multiplication tables – and why we still know the Big Mac jingle.

Our brains also take some surprising shortcuts. In a study published in the Journal of Personality and Social Psychology, Virginia Tech psychologist Kimberlee Weaver shows that the more easily we recall something the more likely we are to think of it as being true. It’s a useful shortcut since, typically, easily recalled information really is true. But combine this rule with the brain’s tendency to better remember bits of information that are repeated frequently, and we can run into trouble: We’re likely to believe anything we hear repeated frequently enough. At FactCheck.org we’ve noted how political spin-masters exploit this tendency ruthlessly, repeating dubious or false claims endlessly until, in the minds of many voters, they become true. Making matters worse, a study by Hebrew University’s Mayo shows that people often forget “denial tags.” Thus many people who hear the phrase “Iraq does not possess WMDs” will remember “Iraq” and “possess WMDs” while forgetting the “does not” part.

The counter to this requires an understanding of how it is that the brain forms beliefs.

In 1641, French philosopher René Descartes suggested that the act of understanding an idea comes first; we accept the idea only after evaluating whether or not it rings true. Thirty-six years later, the Dutch philosopher Baruch de Spinoza offered a very different account of belief formation. Spinoza proposed that understanding and believing happen simultaneously. We might come to reject something we held to be true after considering it more carefully, but belief happens prior to the examination. On Spinoza’s model, the brain forms beliefs automatically. Rejecting a belief requires a conscious act.

Unfortunately, not everyone bothers to examine the ideas they encounter. On the Cartesian model, that failure results in neither belief nor disbelief. But on the Spinozan model we end up with a lot of unexamined (and often false) convictions.

One might rightly wonder how a 17th-century philosophical dispute could possibly be relevant to modern myth-busting. Interestingly, though, Harvard psychologist Daniel T. Gilbert designed a series of experiments aimed specifically at determining whether Descartes or Spinoza got it right. Gilbert’s verdict: Spinoza is the winner. People who fail to carry through the evaluation process are likely to believe whatever statements they read. Gilbert concludes that “[p]eople do have the power to assent, to reject, and to suspend their judgment, but only after they have believed the information to which they have been exposed.”

Gilbert’s studies show that, initially at least, we do believe everything we hear. But it’s equally obvious that we reject many of those beliefs, sometimes very quickly and other times only after considerable work. We may not be skeptical by nature, but we can nonetheless learn to be skeptical. Iowa State’s Gary Wells has shown that social interaction with those who have correct information is often sufficient to counter false views. Indeed, a study published in the Journal of Applied Psychology by the University of Southern California’s Peter Kim shows that meeting a charge (regardless of its truth or falsity) with silence increases the chances that others will believe the claim. Giving false claims a free pass, in other words, is more likely to result in false beliefs (a notion with which 2004 presidential candidate John Kerry, who didn’t immediately respond to accusations by a group called Swift Boat Veterans for Truth about his Vietnam record, is all too familiar).

So, yes, a big ad budget often trumps the truth, but that doesn’t mean we should go slumping off in existential despair. You see, the Spinozan model shows that we will believe whatever we hear only if the process of evaluating those beliefs is somehow short-circuited. Humans are not helpless automatons in the face of massive propaganda. We may initially believe whatever we hear, but we are fully capable of evaluating and rejecting beliefs that turn out not to be accurate. Our brains don’t do this naturally; maintaining a healthy skeptical attitude requires some conscious effort on our part. It also requires a basic understanding of logic – and it requires accurate information. That’s where this Web site comes in.

If busting myths has some bad consequences, allowing false information to flow unchecked is far worse. Facts are essential if we are to overcome our brain’s tendency to believe everything it hears. As a species, we’re still pretty new to that whole process. Aristotle invented logic just 2,500 years ago – a mere blink of the eye when compared with the 200,000 years we Homo sapiens relied on our brain’s reflex responses to avoid being eaten by lions. We still have a long way to go. Throw in a tsunami of ads and Internet bluster and the path gets even harder, which is why we’re delighted to find new allies at PolitiFact.com and the Washington Post’s FactChecker. We’ll continue to bring you the facts. And you can continue to use them wisely.
