Sticky: Becoming mobile-friendly

There's currently a lot of excitement among web designers about Google's announcement that they will penalise sites that don't work well on mobile devices. I've decided I need to comply with this although with less than total enthusiasm. Nearly all my pages now meet Google's new criteria (the only exception is my cycling pictures.)

The disadvantage of the change is that if you read my pages on a desktop or laptop the lines will be long (unless you adjust the width of your browser, of course). Perhaps I should have alternatives for people who are using those devices, though that would mean more complication and difficulty in maintaining both alternatives. And the variety of ways that web pages can be viewed has increased enormously, so it isn't possible to cater for all of them. Probably it's no longer a good idea to specify the width of one's lines as I did previously.

I'd be grateful for feedback on this.

Book review: Psmith in the City, by P.G. Wodehouse

The novels in which Psmith appears were written early in Wodehouse's career, before the first world war; this one was published in 1910. It has two main characters, Psmith and Mike, who is Psmith's friend from school and an enthusiastic cricketer. The two young men are sharing Psmith's flat in Clement's Inn, because both, for different reasons, have reluctantly started work in the City branch of a Far East bank.

Neither man is suited to life in banking and the humour comes mostly from Psmith's dealings with the bosses they encounter, especially the manager, Mr Bickersdyke. Psmith, a languid Old Etonian with an eyeglass, addresses everyone as Comrade and speaks in a formal, mannered, yet comic tone. He is, of course, the central character in the book, although we see events mainly through Mike's eyes. Psmith reminded me of another Wodehouse character, Jeeves. His attitude to his bosses—at once studiously respectful yet discreetly superior—also recalls that of Jeeves to his employer Bertie Wooster. Psmith's distress at the sartorial indiscretions of a young employee in his department is yet another echo of Jeeves.

The story has an autobiographical element. From Wikipedia I learn that Wodehouse, like his two main characters, was compelled as a young man to work, very unwillingly, in the London branch of a Far East bank (both he and Mike had fathers who had suffered financial losses which required their sons to take this course).

In spite of its age the book stands up well to a modern reading; the humour is timeless. It won't disappoint anyone who loves the mature Wodehouse oeuvre.

Should the healthy elderly be taking daily aspirin?

It has become quite fashionable for healthy people to take low-dose aspirin daily to reduce the risk of heart attack and stroke (primary prevention) , although most of the evidence on which this is based comes from trials in people who have already suffered from cardiovascular disease (secondary prevention). It's not clear if the possible benefit outweighs the risk of bleeding for those who are healthy.

A new paper in the New England Journal of Medicine looks at the question in relation to older people (those over 70). The use of low-dose (100mg) enteric-coated aspirin over a median 4.7 year period did not prolong disability-free survival in this group. There was an increased incidence of serious bleeding in those taking aspirin (DOI: 10.1056/NEJMoa1800722).

Book review: Ludwig Wittgenstein, by Ray Monk

See 570 other reviews

Monk tells us in his introduction that people interested in Wittgenstein fall into two groups. Professional philosophers generally study his work without reference to his life, while the many readers who are fascinated by his life and personality find his philosophy unintelligible. Monk's aim is to bridge the gap between his life and his work and to show 'the unity of his philosophical concerns with his emotional and spiritual life'.

To accomplish this, he needed both to present a full account of the man and also to explain the main ideas of his philosophy. I should say he succeeds admirably in the first aim; as for the second, his success is perhaps only partial, but that was probably inevitable, because the difficulty of Wittgenstein's philosophy is different in kind from what is the case with most philosophers. The particular value of Monk's book is that he explains exactly where this difficulty lies. In fact, it has at least two roots.

First, philosophers' writing may be difficult either because they express themselves obscurely or because their ideas are intrinsically difficult to understand. Wittgenstein's difficulty is not exactly from either of these causes. He expresses himself very clearly, often in quite short sentences that are, in a sense, easy to understand; but he nearly always leaves you without the reference points you would expect. In particular, he completely refuses to announce any general conclusions, and this makes it hard to see the point of his remarks. 'As he himself once explained at the beginning of a series of lectures: "What we say will be easy but to know why we say it will be very difficult."'_(p.338)

Many non-professional readers probably get no further than dipping into the Tractatus, which is Wittgenstein's first published work and the only one to appear in his lifetime. It largely achieved its final form when Wittgenstein was a prisoner-of-war of the Italians at the end of the First World War. I found Monk's short paragraph describing this work to be illuminating (p.155).

In its final form, the book is a formidably compressed distillation of the work Wittgenstein had written since he first came to Cambridge in 1911. The remarks in it, selected from a series of perhaps seven manuscript volumes, are numbered to establish a hierarchy in which, say, remark 2.151 is an elaboration of 2.15, which in turn elaborates the point made in remark 2.1, and so on. Very few of the remarks are justified with an argument; each proposition is put forward, as Russell once put it, 'as if it were a Czar's ukase'. … [The propositions] are all allotted a place within the crystalline structure, and are each stated with the kind of finality that suggests they are all part of the same incontrovertible truth.


This exemplifies the difficulty described above. But there is a second kind of difficulty as well. To understand Wittgenstein seems to require a kind of moral seriousness on the part of the reader, particular in the case of his later work, the Philosophical Investigations, published posthumously.

Philosophical Investigations—more, perhaps, then any other philosophical classic—makes demands, not just on the reader's intelligence, but on his involvement. Other great philosophers' works—Schopenhauer's World and Representation, say—can be read with interest and entertainment by someone who 'wants to know what Schopenhauer said'. But if Philosophical Investigations is read in this spirit it will very quickly become boring and a chore to read, not because it is intellectually difficult but because it will be practically impossible to gather what Wittgenstein is 'saying'. For in truth he is not saying anything; he is presenting a technique for the unravelling of confusions. Unless these are your confusions the book will be of very little interest. (p.366)


Given this, there may be a temptation to wonder whether Wittgenstein's importance as a philosopher has been overstated. But this idea is hard to sustain in view of the impact that his ideas have had.

By 1939 he was recognised as the foremost philosophical genius of his time. 'To refuse the chair [of philosophy at Cambridge] to Wittgenstein', said C.D. Broad, 'would be like refusing Einstein a chair of physics.' Broad himself was no great admirer of Wittgenstein's work; he was simply stating a fact (p.414).

Long before this, Wittgenstein had had 'a decisive influence on Bertrand Russell's development as a philosopher—chiefly by undermining his faith in his own judgement.' (p.80) Their first encounter occurred in 1911, when Wittgenstein, then a student in aeronautical engineering at Manchester University, arrived unannounced at Russell's rooms in Trinity College, Cambridge. Russell later reported that 'an unknown German appeared, speaking very little English but refusing to speak German. He turned out to be a man who had learned engineering at Charlottenburg, but during this course had acquired, by himself, a passion for the philosophy of mathematics & has now come to Cambridge on purpose to hear me.' (p.38) Russell initially thought him a crank but later decided he was a genius. Looking back on their meeting three years later, Russell described it as 'an event of first-class importance in my life', which had 'affected everything I have done since'. (p.80)

Wittgenstein was at first 'passionately devoted' to Russell but later considered him to be 'not serious', which, for Wittgenstein, was a damning indictment that reflects a profound difference in temperament. Wittgenstein, unlike Russell, was fundamentally religious. As Monk makes abundantly clear, this theme runs through all Wittgenstein's philosophy. It appears as early as the Tractatus, where the concluding remarks are explicitly mystical and the book ends with the famous line: 'Whereof one cannot speak, thereof one must remain silent.' Before reading Monk's book I had been aware of this mystical element, but I hadn't realised the extent to which it pervades practically everything Wittgenstein wrote.

Religion first appears in the account of Wittgenstein's experiences during the First World War, when he volunteered to serve in the Austrian army in order to experience suffering. This, not surprisingly, altered his outlook on life permanently. At one point he came near to suicide (three of his brothers did kill themselves) but was saved by reading the only book he could find in a bookshop he visited: Tolstoy's Gospel in Brief. This brought about a religious conversion, albeit of a special kind.

One might expect that Wittgenstein, as a philosopher, would discuss intellectual arguments for God's existence, but that is something he very definitely rejected. Towards the end of his life he heard a radio discussion between A.J. Ayer and Father Copleston on 'The Existence of God'. His reaction was not what one might have anticipated.

Ayer, Wittgenstein said, 'has something to say but he is incredibly shallow'. Copleston, on the other hand, 'contributed nothing at all to the discussion'. To attempt to justify the beliefs of Christianity with philosophical arguments was entirely to miss the point. (p.543).


For Wittgenstein, religious belief is psychological: 'he does not see it as a question of whether Christianity is true but of whether it offers some help in dealing with an otherwise unbearable and meaningless existence. … And the "it" here is not a "belief" but a practice, a way of living.' (p.122)

Wittgenstein himself puts it like this:

Life can educate one to a belief in God. And experiences too are what bring this about; but I don't mean visions and other forms of experience which show us the 'existence of this being', but, e.g., suffering of various sorts. These neither show us an object, nor do they give rise to conjectures about him. Experiences, thoughts,—life can force this concept on us. (p.572)


Deciding how to live, and feelings of guilt at when he failed to live 'decently', preoccupied Wittgenstein throughout his life. At one point he insisted on making a formal 'Confession' to a number of his acutely embarrassed friends, although there is little information about what he actually confessed. He had a strong tendency to asceticism. As a young man he inherited vast wealth from his father but he gave it all away. He was attracted by the idea of becoming a monk at various times in his life and tried to do so on one occasion, but was told by 'an obviously perceptive Father Superior' that he was unsuited to this. He spent long periods living in semi-isolation in Norway, which no doubt reflects this side of his character.

A friend remarked on Wittgenstein's 'Hebraic' conception of religion, meaning the sense of awe which one feels throughout the Bible (p.540). I can see this, but it also occurs to me that Wittgenstein might have found Buddhism, at least its Theravada form, sympathetic, given its lack of emphasis on belief. So far as I know this didn't occur to him, which is perhaps surprising in view of his fondness for Schopenhauer, who was much attracted to Buddhism.

Although Wittgenstein was nominally a Roman Catholic, since that was his family religion, it seems to have left little trace in him; he was actually quite surprised to be told of the traditional Catholic belief in Transsubstantiation (the doctrine that the Host literally becomes the body and blood of Christ during the Mass). Two of his friends converted to Catholicism and he worried that he might have been partly responsible for this, unwittingly, by encouraging one of them to read Kierkegaard.

He has a brilliant simile to describe the difficulty of sustaining religious beliefs of this kind.

An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it. (p.463).


He had the greatest respect for those who could perform this feat but he did not think he could emulate it himself. He also had a lot of respect for primitive magic, of the kind reported by anthropologists from remote parts of the world, saying: 'All religions are wonderful … even those of the most primitive tribes. The ways in which people express their religious feelings differ enormously.'

On the other hand, he had a profound distrust of science and he disliked books of popular science, such as Sir James Jeans's The Mysterious Universe, which he thought inculcated a kind of idol-worship of science and scientists. (I can imagine what he would have said about Richard Dawkins.) A fascinating sidelight on this comes from a series of lectures on mathematics which he gave at Cambridge, with the specific aim of countering the adulation of science. Among those who attended, at least for a time, was Alan Turing, who himself was lecturing on 'The Foundations of Mathematics' at the time. (p.417)

The lectures often developed into a dialogue between Wittgenstein and Turing, with the former attacking and the latter defending the importance of mathematical logic. Indeed, the presence of Turing became so essential to the theme of the discussion that when he announced he would not be attending a certain lecture, Wittgenstein told the class that, therefore, that lecture would have to be 'somewhat parenthetical'. (p.417)


There seems to have been no true meeting of minds between the two participants in these discussions, and ultimately Turing ceased attending.

When told by his doctor that he had only a few days to live, he replied: 'Good'. But his last recorded utterance was: 'Tell them I've had a wonderful life.'

In spite of his rejection of Catholic beliefs, his friends arranged for him to have a Catholic funeral. Monk thinks this may have been appropriate, 'for, in a way that is centrally important but difficult to define, he had lived a devoutly religious life.' (p.591)

Book review: Beyond Weird, by Philip Ball

See 570 other reviews

Philip Ball is a science writer who was for many years an editor for physical sciences at the journal Nature. The subtitle indicates what his book is about. It is aimed at readers of books on popular science who have, Ball believes, been given a misleading impression of quantum physics, starting with the notion that it is 'weird', which Ball thinks is a cop-out. It's non-intuitive but not weird. The idea that it is

comes from our (understandably) contorted attempts to find pictures for visualizing it or stories to tell about it. Quantum physics defies intuition, but we do it an injustice by calling that circumstance 'weird'.


Quantum mechanics has the reputation of being probably the most obscure and difficult branches of science, but Ball insists that it isn't 'hard' in the way that car maintenance or learning Chinese are hard (his examples). That isn't to say that a slight readjustment of our intuitions will make everything suddenly explicable. 'Indeed, it is possible that we might never be able to say what quantum theory "means".'

Ball offers new ways of looking at all the hoary old chestnuts of popular accounts of quantum science: the double slit experiment, Schrödinger's cat, entanglement and non-locality (Einstein's 'spooky action at a distance') and the rest. On all these topics he makes one question the ideas one has acquired by reading popular accounts of them previously. His approach is based on work by a number of physicists in the last decade or two.

A central problem we are always told about in books of this kind concerns how the classical world of everyday objects, including us, emerges from the mysterious quantum world. This occurs thanks to something cryptically described as 'collapse of the wave function' Ball seeks to explain this, and much else, in terms of information. Quantum experiments take place within a wider classical environment, and what happens is that 'information gets out of the quantum system and into the macroscopic apparatus'.

There's then no longer any need for an ambiguous and contentious division of the world into the microscopic, where quantum rules, and macroscopic, which is necessarily classical. We can abandon the search for some hypothetical 'Heisenberg cut' where the two worlds impinge. We can see not only that they are a continuum but also why classical physics is just a special case of quantum physics.

On this interpretation there is no need for the radical 'many worlds' solution famously proposed by Hugh Everett III, according to which the world is continually splitting into different branches, in which innumerable copies of each of us continue to pursue different destinies. Ball treats this theory at some length and concludes that it is both unnecessary and unworkable.

Although this is mostly a book about theories, it does contain a quite lengthy discussion of quantum computers. This is included both as an illustration of the practical importance of quantum physics and also because Bell thinks that the questions it raises help to illuminate quantum physics. Perhaps the most striking thing to emerge from this is the fact that no one is entirely sure how these machines actually work. _

Ball is an experienced writer and he treats his subject with a light and often humorous touch, so the book isn't heavy reading even though one has to take it slowly because of the complexity and unfamiliarity of many of the ideas. Ball's usual method of approaching these is a little like a Socratic dialogue. Instead of coming straight out with what he thinks, he proposes possible answers to questions and then shows why they won't do, before offering an alternative; sometimes there are several stages in this process.

I've read a good many popular accounts of quantum theory in the past and had decided that I felt no great inclination to embark on any more. But I made an exception in this case and am glad I did, because I found I was genuinely being given a different way of thinking about the apparent paradoxes that swirl about the subject.

Book review: The Roots of Romanticism, by Isaiah Berlin

See 570 other reviews

In 1965 Berlin gave a series of six lectures on romanticism at The National Gallery of Art, Washington DC. He spoke with notes but no script. This volume has been edited by Henry Hardy, using transcripts as well as BBC recordings of the lectures, which gives the text an unusual degree of freshness and informality. Berlin had hoped to use the material as the basis for a full-length book but this didn't happen. The title of this compilation was chosen by Hardy.

'Romanticism' is notoriously difficult to define (a bit like 'religion') and Berlin explains at the outset that he isn't going to try. But, whatever it is, it's certainly important.

The importance of romanticism is that it is the largest recent movement to transform the lives and the thought of the Western world. It seems to me to be the greatest single shift in the consciousness of the West that has occurred, and all the other shifts which have occurred in the course of the nineteenth and twentieth centuries appear to me in comparison less important, and at any rate deeply influenced by it (p.1).


Before reading this book I had a vague idea that romanticism originated in England, with poets like Shelley, Keats, Coleridge and Wordsworth, and Berlin agrees that this is what most historians tell us; but he ascribes the primary role to Germany, and the book is mainly although not exclusively concerned with German writers.

Romanticism was a reaction to the values of the Enlightenment, with which France is particularly associated. We think of France in the late eighteenth century as characterised by reason, rejection of religion, and the advance of science—all of which culminated, perhaps unexpectedly, in the turmoil of the Revolution. Germany, meanwhile, was very different. While France was a unified, centralised and powerful state, Germany was split up into hundreds of small principalities and was, in consequence, relatively weak. Huge numbers of Germans had been killed by foreign troops, including those of France, in the Thirty Years War; nothing on this scale had been seen in Europe before. 'The truth about the Germans in the seventeenth and eighteenth centuries is that they constitute a somewhat backward province' (p.34).

There was also a class division between Germany and France, Most of the prominent German writers—Lessing, Kant, Herder, Schelling, Schiller, Hölderlin—were lower middle-class, whereas nearly all the French radicals were upper-class, and many from the nobility. Hence a social chasm existed between the German intellectuals and the French; when Herder came to Paris in the 1770s he was unable to meet any of the French cultural elite.

Against this background there developed in Germany a religious mood, the pietist movement, which Berlin sees as the root of romanticism. Pietism was a branch of Lutheranism and consisted in closely studying the Bible and attending to man's relation to God. So we get an emphasis on spirituality and contempt for learning. 'What occurred was a kind of retreat in depth.'

Why pietism should have lead to romanticism isn't immediately obvious, but Berlin thinks it was largely due to one man, of whom most people today probably haven't even heard: Hamann.

My reason for introducing the obscure figure of Johann Georg Hamann is that I believe him to have been the first person to declare war upon the Enlightenment in the most open, violent and complete fashion. Nevertheless, he was not entirely alone in this, even in his own lifetime (p. 46).


Hamann was born in obscurity and lived a dissolute life for a time, but when he was at the point of suicide he had a religious revelation and became a writer. He was not successful at this either—Berlin describes his style as unreadable—yet for some reason he had a very strong influence on a number of other writers who did have a profound influence in Europe, including Herder, Goethe, and Kierkegaard.

Hamann's fundamental doctrine … was that God was not a geometer, not a mathematician, but a poet; that there was something blasphemous in attempting to foist upon God our own human, logical schemes (p.48).


Yet another writer who appears in association with Hamann is Immanuel Kant, who was Hamann's neighbour and friend. I hadn't thought of Kant as a figure in the romantic movement and in fact he hated it, yet Berlin identifies him as one of the fathers of the movement, because of his 'virtual intoxication' with the idea of human freedom. For this reason he welcomed the French Revolution (likewise the American Revolution), and even the Terror did not lead him to revise his view completely.

This indicates the passion with which this normally very conventional, very obedient, very tidy, old-fashioned, somewhat provincial East Prussian professor nevertheless regarded this great liberating chapter in the history of the human race, the self-assertion of human beings against huge idols as he thought of them, standing over against them. … He is not normally thought of in these terms, but there is no doubt that his moral philosophy is firmly founded upon this anti-authoritarian principle (p.77).


Although Berlin concentrates mainly on literature, he also looks at music and painting and even economics. It is here that, for me, what he has to say resonates most strongly with our present situation. The Revolution showed people that they had been paying too much attention to the upper portion of society—economists, psychologists, moralists, writers—intellectuals of every kind; but these were merely the tip of 'some huge iceberg of which a vast section was sunk below the ocean'.

This invisible section had been taken for granted a little too blandly, and had therefore avenged itself by producing all kinds of exceedingly unexpected consequences (p.110).


Indeed.

This is a short book but a rich one, brimming with ideas and extremely readable. It has certainly very considerably changed how I think about the romantic movement. For me, at any rate, its great merit is that it has introduced me to a range of German writers who were previously little more than names to me. It also let me see Kant in a new way. Encouragement to further exploration comes in the shape of a reference section at the end, although Hardy warns us that identifying sources for this 'most effervescent of historians' is no easy task.

In memoriam: Dr Peter Fisher

I 've just received the sad news of the death of Dr Peter Fisher in a cycling accident in High Holborn, near The Royal London Hospital for Integrated Medicine, where he had been a leading clinician for many years.

Peter was a good friend and colleague in my years at the hospital, where he was consultant physician and Director of Research, as well as Editor-in-Chief of the journal Homeopathy. He was a convinced homeopath but always took an evidence-based approach to the subject; for example, he criticised opposition to vaccination on the part of some homeopaths as unscientific (and contrary to homeopathic principle).. Nevertheless he was largely responsible for changing the name of the hospital from The Royal London Homeopathic Hospital to its present form in 2010. This was a wise move which reflected the fact that the hospital now offers a range of complementary treatments, always in the wider context of modern clinical medicine.

Peter's death will be an irreplaceable loss to British homeopathy.

Book review: The Crossway, by Guy Stagg

See 570 other reviews

n 2013, following his partial recovery after a long period of mental illness, which included alcoholism and a suicide attempt, Guy Stagg set out on a pilgrimage from Canterbury to Jerusalem, following medieval pilgrim routes. Although an atheist, he hoped that the religious ritual of pilgrimage would somehow heal him after his illness. He walked for ten months and covered 5,500 km, passing through 11 countries if you include England.

This is a travel book in at least two senses: it narrates the author's arduous journey on foot and it also describes the accompanying inner journey through his own mind and memories. It's a long book—over 400 pages—and I have to say that I found reading it somewhat of a pilgrimage myself. I needed to take breaks in which I read other books to change the mood. Although there is certainly a sense of constant movement through different landscapes and variety in the encounters with people met on the way, this did not always counteract a sense of claustrophobia induced by the author's descriptions of his earlier depressive states.

This wasn't because of any lack of skill on Stagg's part—quite the contrary. He is a very 'literary' writer (some have compared him to Patrick Leigh Fermor) and the book is artfully constructed. The writing is complex and allusive and demands slow reading. The title reflects this, combining as it does multiple meanings within itself: the choosing of paths, suffering, Christ's cross, and a reference to the fact that in earlier times suicides were buried at crossroads rather than in consecrated ground; no doubt there are other meanings to be teased out as well.

Stagg began his journey on New Year's Day, which seems an eccentric choice, given that he would have to cross the Alps in midwinter on foot, but he felt that if he postponed starting until summer he would probably never go at all. The Saint Maurice pass in a snowstorm was quite as hazardous as one would expect, and even when he reached the other side the dangers didn't disappear. He nearly drowned trying to cross a river by a shaky footbridge and then was almost run over by a train when he used a railway bridge instead.

There is plenty of drama in the story, but Stagg's main interest is less in his adventures or misadventures than in the people he met along the way. Some of his encounters, related with deadpan humour, are very funny, but the dominant impression we get is of the extraordinary kindness of strangers. Often he stayed in monasteries or presbyteries, but also in private houses, and nearly always he was made welcome—until, ironically, he reached the Holy Land. The Turkish villagers were particularly hospitable and he acquired enough knowledge of their language to converse with them.

What one would expect to be the high .points of the journey, Rome and Jerusalem, were somewhat anticlimactic; especially Rome, where the Easter crowds occasioned panic and a psychological collapse. Later, in Greece, he went on an alcoholic spree in Thessaloniki and then was overwhelmed by a sense of failure. More than once, not surprisingly, he thought of giving up, and in fact decided he would do so when he reached Istanbul. But after making friends there and joining them in anti-government riots enlivened by tear gas, he changed his mind and went on.

So why didn't he give up? I don't think this was entirely clear, even to him. He no longer believed that the pilgrimage would heal him psychologically. But the root cause of his continuing seems to have been that he has, to a marked degree, what Thomas Nagel has called the religious temperament. He remained a convinced atheist but he found a deep meaning in religious ritual, at least in the form of the pilgrimage. His attitude to religious ceremony was more complex; he attended Catholic services in the monasteries where he stayed but what they meant to him is less clear..

He includes a good deal of historical information about the places he passed through. Some of this is well known (the First Crusade, the abolition of the Templars), some less so (the Bogomil heresy). He is evidently well read in this respect, which makes his reaction to Eastern Orthodox religion rather surprising. He apparently knew little about it in advance of his arrival in Greece and was disconcerted by its unfamiliarity, although his attitude changed somewhat after he spent a few days on Mount Athos. Here he met two Western converts to Orthodoxy who made the faith more comprehensible to hjm. He followed this up with a conversation with a monk in one of the monasteries he stayed at. The monk asked him to stay on indefinitely, and for a moment Stagg contemplated the possibility, before thanking the man hastily and making his escape.

He had to depart from his planned route after leaving Istanbul, owing to the civil war in Syria. He made a detour through Cyprus keeping to the high ground because of the heat. He crossed back to Lebanon, where he narrowly escaped a terrorist bombing in Tripoli. He reached Beirut, but then had to take a plane and several buses to Amman, before continuing his journey on foot over the Golan Heights into Israel.

The end of the book brings no final resolution or illumination. In an epilogue he describes leaving Jerusalem and heading south. He passes through Bethlehem but does not visit the Church of the Nativity because what he wants to see is the desert, which he describes as the most beautiful landscape he has ever seen. Arriving in the afternoon at an Orthodox monastery, he is refused accommodation because he has no letter from the Patriarch. He is advised to spend the night in a cave on the far side of the valley, which he does. Next day, he says, he will continue walking east.

Book review: On Faith and Science, by Edward J. Larson and Michael Ruse

See 570 other reviews

The relation between religion and science has a long history and it has gone through various phases, some amicable, some not. At present, thanks partly to a loosely knit group of writers who have been called the new atheists—Richard Dawkins, Daniel Dennet. A.C. Grayling and others—relations are bad. But there are some non-believers who want to find common ground with religion, and Ruse has long been one of these; not that you would know it from this book, for both he and his co-author Larson are reticent about their own religious views.* No doubt this is due to a wish to appear even-handed, but I think it leads to a certain softening of focus throughout.

Both authors are distinguished academics. Larson is a historian; Ruse is primarily a philosopher of science who also has an interest in history, particularly that of the theory of evolution (see links to my reviews of books under his name in the list of authors). They write alternate chapters, although there is some flexibility, with some chapters containing contributions from both, and it isn't always easy to be sure who is writing at a given moment.

There are chapters looking at cosmology; physics; brain, mind, and soul; geology; evolution in general; and human evolution. The approach in these is historical; they look at how knowledge has evolved over time and how this has interacted with religion—mainly Christianity, but there is some reference to Judaism and Islam and a little to Hinduism and Buddhism. For each topic we get an outline of some of the religious issues that growth in our knowledge has given rise to. It is all done well enough, but there will be few surprises for anyone who is reasonably familiar with the subjects covered.

The last three chapters (7, 8 and 9) are a little different, in that they cover matters that are topical (and controversial) today: sex and gender, eugenics, and living on earth (which looks at global warming and other threats to our survival). In their closing paragraph the authors use the common ground they think exists between two very different people, Pope Francis and E.O. Wilson, to draw a moral for the relationship that ought to obtain between science and religion as it relates to our survival.

I'm sympathetic to the authors' wish to avoid facile condemnation of religion in the name of science, but I enjoyed reading this book less than I expected to. The tone is quite colloquial, almost to a fault, yet at the same time bland and a little flat. And at times the authors' evident desire to avoid giving offence becomes somewhat irritating. For example, they quote from Fritjhof Capra's 1975 book The Tao of Physics and remark that 'he remained an outlier among modern physicists', which seems a considerable under-statement; I wanted to know what they thought of it themselves. They are also fairly non-commital in their references to Richard Dawkins's book The God Delusion, about which Ruse has been scathingly critical elsewhere.

The book concludes with an eclectic annotated bibliography which is quite useful, although I was sorry to see no mention of Taner Edis's books, especially his The Ghost in the Universe, which to my mind is one of the best books on theism by a sceptic who nevertheless takes religion seriously. He has also written well on science and Islam, something touched on only briefly in the present book.

*Ruse has recently publicly identified himself as an atheist, although he prefers the term 'sceptic'. See Why I Think the New Atheists are a Bloody Disaster.

Book review: An Introduction to Western Medical Acupuncture (Adrian White, Mike Cummings, Jacqueline Filshie)

See 570 other reviews

This is a book about the modern medical version of acupuncture, often called Western medical acupuncture (WMA) which is widely practised by health professionals today. It is the second edition of the work (the first appeared in 2008) and is described as a companion to Medical Acupuncture: A Western Scientific Approach (Elsevier, Edinburgh, 2016), now also in its second edition. The authors are all among the foremost proponents of WMA in Britain and so are well placed to produce a book of this kind.

Its primary intended audience is health professionals who have recently completed a training programme in modern acupuncture and want to consolidate and extend their knowledge of the subject. But it will also interest more experienced practitioners, because it includes a large amount of up-to-date research evidence for acupuncture that is otherwise not easy to find gathered together in an accessible form.

The book has 19 chapters. Chapter 1 is an introduction and provides a description of WMA and how it differs from traditional Chinese medicine (TCM). The remaining chapters are divided into five sections: 1. Principles; 2. Effects Mechanisms Techniques; 3. The Evidence Base; 4. Practical Aspects; 5. Treatment Manual. There are also five detachable cards illustrating classical acupuncture points, myofascial trigger points, and pain referral zones. As this summary will indicate, there is a progressive shift in focus throughout the book, from evidence for acupuncture as a science-based treatment to the practical aspects, but this is not a rigid separation and even the more research-oriented sections bring out the practical implications of what they describe.

I shall now look at the individual sections in more detail.

Section 1 has three chapters (Chapters 2–4). The first is a preliminary overview of what WMA is and how it is thought to work. Acupuncture is mainly although not wholly a treatment for pain, and Chapter 3 looks at the modern understanding of pain mechanisms in the nervous system and how these relate to acupuncture. Chapter 4 describes some basic acupuncture techniques, to be elaborated later.

Acupuncture modernists always have to decide where they stand on the question of classical acupuncture points. Some, of whom I am one, prefer to avoid that terminology almost completely, but here the authors do use it, although with reservations. 'This book uses classical acupuncture point names as a convenient convention, though each point's effects are not as specific as traditionally believed, and nerves may be stimulated effectively almost anywhere in the body.'

What I found particularly welcome both in this section and throughout the book is the absence of dogmatism. The authors state their views but they recognise the existence of different approaches to treatment within the broad scope of modern medical acupuncture: 'nothing in acupuncture should be standardized—except safety.'

Section 2 is concerned with the mechanisms of acupuncture—how it works. A lot of new research on the question has become available since the first edition in 2008. The physiological mechanisms are discussed under a number of headings: local effects, segmental (spinal) effects, and general (central) effects. There is too much information here to summarise in a review, but this is an important section because it provides much of the support for the authors' treatment recommendation in later chapters.

This section includes a description of myofascial trigger points (MTrPs), which figure prominently in WMA. This is particularly useful for doctors, who are unlikely to have encountered the subject in their ordinary clinical training. It is treated here both theoretically and practically, including an account of how to diagnose and treat MTrPs.

The concluding chapter in this section is on traditional Chinese medicine (TCM). There is a succinct account of the ancient ideas and the authors consider how relevant, if at all, TCM concepts are to modern practice. 'A rational approach based on knowledge obtained scientifically can explain many of the concepts of TCM.'

The authors provide a fair summary of TCM but I question whether it is still necessary to include it in a book on WMA. I think we are rapidly approaching, or have already passed, the point where the subject can be regarded as of purely historical interest, in which case it could be omitted or at least relegated to an appendix.

Physiology is important in modern acupuncture but we also need clinical evidence of efficacy, and this is the subject of Section 3. Critics sometimes claim that acupuncture is 'just a placebo' because many trials find little or no difference between 'real' and 'sham' acupuncture. But this begs many questions, especially the problem of what constitutes a 'sham' acupuncture treatment. The authors show convincingly why it is so difficult to devise an adequate placebo treatment in acupuncture. Nor is this the only practical difficulty that attends clinical trials in this field. For example, 'blinding' of patients can be difficult (blinding of the practitioner is all but impossible). In spite of these difficulties there is good evidence of efficacy in at least some disorders.

Safety is a literally vital consideration in acupuncture and Section 3 concludes with a chapter reviewing the evidence on this question. The authors find that acupuncture is generally safe if done by adequately trained practitioners and is usually safer than most other treatments that are available. Aggravation of symptoms may occur but is seldom severe and is certainly not required for effective treatment, as is sometimes claimed, so the risk should be reduced as much as possible.

Questions of safety again figure prominently in Section 4. The first three chapters in this section (14, 15, 16) 'are essential reading for clinical practice'. They cover preparing for treatment, effective needling techniques, and safe needling. All the safety issues mentioned here are incontrovertible, but (as noted earlier) there is room for discussion about some of the techniques described.

For example, the authors advise the use of guide tubes for beginners because they make needle insertion easier. This is true, but many experienced acupuncturists dislike guide tubes and don't use them, and I'm not sure that it is necessary to impose them on beginners. I think that most newcomers to acupuncture quickly learn to insert the needles without them, at least the standard (30mm) needles; the longer (50mm) needles are probably best used with guide tubes, at any rate to start with.

On the question of how long the needles should be left in situ ('retention'), there is a widespread idea that this should be 20 minutes, and the authors think that this may be because it takes this length of time for beta-endorphin levels to reach a maximum in the central nervous system. However, they think that 10 minutes is often long enough for a clinical response. I should say that much briefer insertion is usually effective in most cases, and the authors do acknowledge the use of this technique by some practitioners. Needle retention is probably one of the most widely debated subjects in acupuncture.

The concluding chapter in Section 4 deals fairly briefly with other techniques often bracketed together with acupuncture, such as moxibustion, auricular acupuncture, and the use of lasers. The authors find little advantage in embarking on most of these.

Section 5 is a 'Treatment Manual' describing various possible approaches to try in different disorders. To avoid any misunderstanding, the authors emphasise that this section only makes sense if you have read everything that precedes it; they are not providing 'recipes' or rules to be followed without thought. 'You have discovered the principles of acupuncture in the previous chapters; here you find some guidelines to point you in the right direction.'

The book is very well produced, with abundant diagrams, and is written in an approachable style that makes it easy to read. Each chapter begins with headlines summarising its contents to indicate what the student should learn by reading it, and concludes with a useful review of its main message.

Some acupuncture enthusiasts want to emhasise what they perceive as its differences from mainstream medicine. The alternative view is that acupuncture should be reinterpreted in the light of modern knowledge and integrated with mainstream methods of treatment, and that is the present authors' opinion. 'It is time to reconsider acupuncture and its strange phenomena in ways that are credible to Western science.'

Book review: Beyond Weird, by Philip Ball

Philip Ball is a science writer who was for many years an editor for physical sciences at the journal Nature. The subtitle indicates what his book is about. It is aimed at readers of books on popular science who have, Ball believes, been given a misleading impression of quantum physics, starting with the notion that it is 'weird', which Ball thinks is a cop-out. It's non-intuitive but not weird. The idea that it is


comes from our (understandably) contorted attempts to find pictures for visualizing it or stories to tell about it. Quantum physics defies intuition, but we do it an injustice by calling that circumstance 'weird'.



Quantum mechanics has the reputation of being probably the most obscure and difficult branches of science, but Ball insists that it isn't 'hard' in the way that car maintenance or learning Chinese are hard (his examples). That isn't to say that a slight readjustment of our intuitions will make everything suddenly explicable. 'Indeed, it is possible that we might never be able to say what quantum theory "means".'
