Narziss and Goldmund by Hermann Hesse (1930)

He drew himself, as a wanderer, a lover, a fugitive, with reaping death hard at his heels…
(Narziss and Goldmund, page 228)

‘Narziss’ is a direct transliteration of the name in original German title, Narziß und Goldmund, but the word also translates as Narcissus, which is why some modern editions are titled Narcissus and Goldmund. Goldmund translates literally as ‘gold mouth’, though you can see why this wouldn’t work so well as a title. Narcissus and Gold Mouth might begin to sound too much like a fairy tale.

Narziss and Goldmund is longer than its predecessor novel, Steppenwolf (300 pages in the Penguin edition compared to Steppenwolf’s 250 pages). And it’s far more integrated and coherent than Steppenwolf, which is built up from a number of different texts, echoing the fragmented nature of the protagonist’s divided mind. By contrast, Narziss and Goldmund maintains a calm, lyrical and mellifluous sonority throughout, leading some critics to call it Hesse’s ‘most lyrical’ novel.

Narziss and Goldmund is set in the Middle Ages and both narrative and dialogue are couched in an unobtrusive but persistent cod-medieval style which might irritate some modern readers.

‘Mistress Lisbeth,’ he said, in a friendly voice. ‘I am not come to ask you for work. I wanted to give you greeting – you, and the Master. It irks me sore to have to hear you. I can see you have had much sorrow. If your father’s thankful apprentice can do you a service – name it – it would be my recompense.’ (p.224)

But, as mentioned, it is this low-key but persistent ‘medieval’ style which gives the book its distinctive flavour and tone.

Two opposites

The two central figures are ‘types’ – of the dry intellectual, the analyser and categoriser (Narziss) and the passionate lover of life, wine and women (Goldmund).

The first fifty or so pages describe in some detail how the pair first meet, as young novitiates at the ancient monastery of Mariabronn somewhere in North Germany. Narziss is himself a junior monk but already skilled and educated enough to be put in charge of the monastery school. One day young Goldmund is dropped off by  his father, a knight, who asks the monks to educate him. He never sees his father again. It slowly emerges that he’s never known his mother who, his father told him, was a wanton hussy who ran off when Goldmund was a baby.

This will turn out to be centrally important because there is a sense, in everything that follows, right up until his death, that this missing mother, the search for the Absent Mother, is central to his psyche.

Goldmund goes a wandering

Initially Goldmund is a good scholar. He is ragged by the other boys in fights and taunts which are presumably meant to reflect the bullying of schoolboys everywhere, in all times, but he fights back and establishes a place for himself in the hierarchy. There’s a naughty excursion from the monastery when a bunch of older boys sneak out of the premises to a nearby village, where they drink wine and chat up a peasant’s pretty daughter. She takes a shine to Goldmund, who is fiercely attracted to her and fiercely tries to repress the impulse.

Narziss and Goldmund forge a special bond based on Narziss’s uncanny insight into other people. They have many intense conversations. In one of them Narziss dwells on Goldmund’s absent mother and it comes as a revelation to Goldmund that there is this great hole in the centre of his life, and he breaks down in tears. It is that kind of very intense psychological bonding between the pair which gives the book its title.

But fate is fate, or biology is biology, and Goldmund goes out walking, picking flowers and marvelling at the beauty of the world. He falls asleep and is woken in a half-dream, by a beautiful gypsy girl, Lisa, waking in her lap, as she leans down to kiss him and, to cut a long story short, she takes his virginity, which is described in flowery euphemisms appropriate for 1930.

It is a revelation. Goldmund realises he is never going to be a monk, he’s not even that good a scholar. Goldmund returns to the cloister to tell Narziss he’s leaving, there and then. He packs his bags and leaves. He finds Lisa again the next day, but this time she is scared and runs back to the husband who beats her.

Now commences the long central section of the book where Goldmund goes on the tramp, vagabonding across northern Germany, and – this may be the slightly hard bit for a modern reader to swallow – everywhere he goes he is ‘desired and appeased by women’ (p.98). With his blonde hair, good looks and slim figure, Goldmund is a ladykiller, a babe magnet.

He quickly, comprehensively and intuitively becomes an expert at sex, a connoisseur, ready and able to give every woman what she wants, whether hard and fast, or slow and sensual, responding to all moods and needs. If you’d expected a spiritual classic, it certainly has a lot of deep psychology about life and destiny, but you’ll be surprised by the amount highly sensual, soft porn writing.

Drawn and clasped to one another, they lost themselves within the scented night, saw the white, shimmering secrets of its flowers, plucking its fruits, for which they thirsted, with gentle, ever-grateful, hands. Never before had spielmann struck such a lute, or lute known fingers so strong and cunning. (p.234)

The knight and his daughters

Pages 100 to 122 describe his adventures at a castle. He is taken in by an ageing knight who, when he discovers Goldmund is a scholar, hires him to write the life’s long adventurous life story in Latin. But the knight has two daughters, Lydia and Julia, and they are soon competing for his favours. It takes a bit longer than usual but Goldmund persuades Lydia into his bed where, however, she strips and kisses a little but, irritatingly, refuses to give him what so many other gypsy girls and peasant girls and farmers’ wives have already given him.

Worse, they’re lying there one night when the door opens and in comes the jealous younger sister Julia. Lydia is panicking when Goldmund overrides her and invites Julia to join them in bed. There follows a passage where Goldmund is kissing older, stiff Lydia on one side while with his hand he strokes and then begins to masturbate young Julia on his other side, who begins to make moans of pleasure.

See what I mean about a certain soft-porn 1970s feel? That’s one way of looking at it. The other is to see all these sexy passages as extraordinarily open, candid, honest descriptions of sex for their time (1930), and to place them in the wider context of the books and their serious concerns with human psychology and spirituality. In other words to see that Hesse’s books address the entirety of the human condition, sex and death and bereavement and loss and abandonment and friendship and love and art, and that the lyrically porny sequences are just an unashamed, honest inclusion of the role sex does play in many people’s lives.

This soft porn sequence is, alas, interrupted when the older sister leaps out of bed and threatens to tell their father. Both girls go. But Lydia goes to the knight and tells him everything. Goldmund is rudely awakened the next morning by the knight who is too angry to speak, who grabs his stuff in a bundle and marches him half a mile to the bounds of his land and then tells him never to return on pain of death. It is snowing. Goldmund sets off into the freezing cold.

An hour later, Hans a servant rides after him and delivers gifts from Julia – one golden ducat, an undershirt she has woven, and a side of bacon. Well, it’s something.

Goldmund comes to a village where he begs food and then is conscripted to assist as a villager gives birth, quite a traumatic experience for a young, sensitive mind. Typically what strikes Goldmund is the way the sounds of pain are so close to the sounds of a woman’s ecstasy, which triggers characteristic philosophical meditations. He dallies in the village a while i.e. has a brief ‘affair’ with a brawny village wife, Christine.

Murders Victor the vagabond

In this village he meets another vagabond, Victor. Victor is a seasoned, wily survivor, full of impressive stories of life on the road and Goldmund is taken under his spell. They travel on together for a few days but late one night in the forest, Goldmund wakes up to find Victor stealthily rifling through his clothes looking for the precious gold ducat Goldmund had told him about. When he resists, Victor starts to strangle him, in earnest, so Goldmund finds himself with his last breaths fumbling for the small knife he keeps mainly to cut up bread and cheese, and in a final paroxysm, stabbing Victor again and again and again until the grip round his neck loosens, and the man falls away from him, bleeding profusely from multiple wounds and there and then, in the dark early hours, in a forest in winter, Victor breathes his last, leaving Goldmund staggered and appalled. (p.127)

(And this reader thinking, yet again, that these German novels have a special affinity for knife murder.)

Master Nicholas and the nature of art

Goldmund comes to a nearby city, referred to as the Bishop’s City. On the outskirts he had come across an isolated chapel and been entranced by a sculpture inside it of the Mother of God.

In the city he makes enquiries as to who carved it and discovers it is a certain Master Nicholas the sculptor. To cut a long story short, Goldmund asks to be his apprentice. Nicholas tells him to draw something, anything, on a piece of paper he gives him and the result impresses him enough to take him on.

There follow extended passages meditating on the nature of art, on the meaning of reproducing the world and God’s creatures.

Goldmund realises he has within him the faces and personalities of all the women he’s encountered and realises he must make a particular carving, bringing the essence of all these women together to create a Mother of God.

Goldmund stays with Master Nicholas for two years while he works on this figure. During that period he has many many women – the tradesman’s wives and daughters – including the serving wench in a butcher’s house, Katherine, who he calls his ‘pork and sausage maid’ (p.179).

All through this period he is tormented by the contradictions in art between the soul and the physical, despising little people who are happy with decorations, driven by a striving for the unseeable essence of the subject.

Many lengthy discussions of the nature of true art. Goldmund ponders why Master Nicholas is a master sculptor, all right, but also a journeyman craftsman and that ability, facility, doesn’t interest Goldmund. Goldmund sits by the river and realises it is those endless flashes, light off the ripples, sudden glimpses of pebbles on the riverbed, the light through a butterfly’s wings – all the art in the world can’t compete with the beauty of the actual world.

Meanwhile, Master Nicholas has been thinking and offers to make Goldmund his heir, bring him into his workshop and to marry him to his daughter, Lisbeth. Unfortunately he makes Goldmund this offer at just about the moment Goldmund has realised he doesn’t want to be a journeyman like Nicholas. Nicholas goes white with anger when Goldmund embarrassedly turns down his offer, and makes it plain he must leave immediately.

Rather as he was ordered by the angry knight to leave the castle.

So Goldmund sets off on his rambles again, despite there being so many women in the city of whom he might have taken his leave (p.184). Last, and barely noticed, is the 15-year-old lame daughter of the burghers he’s been rooming with him. As he leaves the city, she offers him a drink of fresh milk and a crust of bread and, out of politeness, he leans down and kisses her. She closes her eyes in bliss. She has had a teenage crush on him all this time but, as in an American magazine romance, Goldmund doesn’t know or care. Then he is back on the road.

The plague

Goldmund hooks up with timid young Robert, a younger tramp. We learn it is ten years since Goldmund left the monastery (p.204). He now has a blonde beard (p.209).

The pair come to a plague village, whose villagers aggressively warn them away. But Goldmund goes in and finds a family dead in their beds, prompting characteristic Hesse reflections about Death. And the artist in Goldmund is attracted by their postures and positions…

As they walk on they discover that the whole countryside is ravaged, abandoned. Coming to an empty town, Goldmund notices a beautiful young woman (of course) leaning out a window and, as usual, picks her up. Her name is Lene (p.198) and she succumbs to Goldmund’s invitation to come with them, packs a small bag and off they go. She is ‘a sweet mistress… shy and young and full of love’ (p.201)

After much wandering they come across abandoned farm buildings, decide to settle there, fix them up and make a life, rounding up stray abandoned animals.

One day Lene and Goldmund go hunting, get separated, he hears her screaming, runs and finds her being raped, grab the scrawny rapist, strangles him and dashes his head to a pulp against rocks.

Goldmund carries Lene home, washes her breast where it has been scratched and bitten so hard it is bleeding. But, somewhat inevitably, Lene gets the plague and dies in a matter of days. Robert refuses to come near the hut she’s in, then runs off never to return.

Goldmund tends Lene till she dies and then, characteristically, studies the face of death. Then he sets fire to the hut, as a funeral pyre and to cleanse it, and hits the road again, wandering through a landscape of horror where the deserted villages and towns are surrounded by plague pits, passing processions of flagellants, watching the lynching of people scapegoated for the disaster, not least the burning alive of Jews in their houses in one town. Horror. The Kingdom of Bones (p.212)

But he watches it all with fascination, soaking up the suffering and despair, never tiring of watching the Grim Reaper at work.

Goldmund stumbles across a beautiful young Jewess (isn’t he lucky to come across so many beautiful young women) weeping beside a big burnt-out fire and discovers this is where 15 Jews from the nearby town were murdered and burned to death, including her father.

Goldmund is touched and offers to take her with him and protect her but can’t stop himself also trying to seduce her with honeyed worlds. Well, for once it doesn’t work. Unsurprisingly, she is disgusted, says all Christians are alike, murderers and hypocrites (and she might well have thrown in the accusation that all men are alike) and runs off.

Goldmund’s head is full of all the images he has seen, a medieval panorama. With increasing urgency he wants to return to ‘the Bishop’s city’ where he lived and worked for Master Nicholas. When he finally arrives back there he is overwhelmed by happy nostalgia of re-seeing all the familiar sights, the old churches, the market square, the clear purling river.

But, inevitably, Master Nicholas is dead of the plague… and his beautiful, haughty daughter, Lisbeth? She is now yellow-faced, gaunt and shrivelled. He offers help but Lisbeth (and the raddled old servant Margret) scorn him.

Wandering the town’s streets Goldmund bumps into lame Marie, who had a teenage crush on him, and she invites him modestly back to her parents’ house. They are honestly glad to see him. Inspired, Goldmund starts drawing hundreds of pictures of everything he’s seen in the Landscape of Death.

Lady Agnes

One day Goldmund is struck by the sight of a haughty beautiful rich woman riding by on a horse. He must have her. It is a challenge. He places himself at the town gates every morning as she goes a-riding. He appears under the trees near where she stops the horse for her daily rest.

After a few days she deigns to talk to him. She gives him a token, a gold necklace, which gives him admittance to the castle. He goes there that evening, claiming to have found the lady’s necklace and wanting to return it. He is allowed into the busy castle courtyard, full of horses and bustle.

The lady’s maid takes him up to her ladyship’s luxury rooms and there, amid the fur and incense, on a rich white bed, he strips and makes love to her, as – inevitably – ‘she has never been loved before’!

If you let yourself go along with this mood, it is a scene of exquisite sensitivity; if you are a little more jaded, it is like an extended Flake advert.

But the next very evening, when he returns for some more soft-focus erotic goings-on, he is trapped and caught by the jealous husband, Count Heinrich.

As the big angry knight opens the bedchamber door, Lady Agnes pushes Goldmund into her closet. Here the knight discovers him but Goldmund is quick witted enough to pretend he is a thief who has broken in to steal the precious dresses and furs.

The count believes him and says he will be hanged in the morning. Goldmund’s wrists are tied and he is led down to a pitch-black dungeon and thrown in. As the churls are unlocking the door to the dungeon, two priests visiting the castle pass by, and one stops to ask if the prisoner is to be confessed and shriven, then tells the guards he will come at dawn to perform this service.

Goldmund spends the night trying to reconcile his soul to death, to never more see the sun or feel the wind or hear the birds. He also spends the whole night freeing his wrists from their tight cords, cutting himself badly in the process. When dawn comes, the door opens and a cowled monk descends the stairs into his cell.

Goldmund is fully prepared to whip up hi stool, dash the monk’s brains out, steal his habit and make a getaway. Imagine his amazement when the monk pushes back his cope and reveals the face of… his old, old, deepest friend, Narziss, now thin and gaunt with asceticism and the responsibilities of command. For Narziss has now become the abbot at Mariabronn.

Narziss raises Goldmund to his feet and says he spent a lot of effort the night before pleading with the angry knight for his life. Result: Goldmund will not hang. Instead the other monks dress his wounds, pack their bags, mount their horses, and ride out of the castle courtyard. Even at this late stage, and despite having learned his lesson, Goldmund still looks up at the windows overlooking the courtyard, hoping the beautiful Lady Agnes will be looking out of one at him. But no.

Goldmund rejoices as his horse carries him through the scenery of all his adventures, he reviews them, the many women, murdering Victor, the cold nights lying in the forest and so on.

Then they reach the old monastery and Goldmund is overcome with memories of his youth. Here he is kindly invited to stay as a guest, with no demands on him to become a lay brother let alone a monk, by his wise old friend.

After a spell of feeling a bit lost and bewildered, Goldmund decides on a plan, which is to work as a carver again, and create a wooden relief spiralling up the steps to a lectern where monks read texts to each other in the refectory.

This penultimate section of the book allows for:

  1. an emotional reunion of Narziss and Goldmund and a series of conversations during which they revive their friendship and remember the old times, the old abbot et al
  2. a series of debates between them about the nature of the scholarly intellectual mind and the artistic creative mind. Goldmund comes to realise he has led a chaotic and disorderly life, but when he tells Narziss how much he admires the other’s purity and devotion, Narziss says that’s only because he knows nothing of his (Narziss’s) intellectual doubts and uncertainties. Both envy the other his clarity and conviction, while both reveal they are, in fact, riven by doubts and uncertainties.

Womanising

Almost all of the long middle section of the book describing Goldmund’s wandering is, in my opinion, a little undermined by his endless womanising.

I take the point that it’s designed to show Goldmund’s immersion in ‘the world, the flesh and the devil’ and so point up the basic dichotomy between the Worldly Personality and the Scholarly, Secluded Personality. My criticism is that these worldly scenes describe the same schoolboy fascination with seducing and stripping nubile young women without any attempt to explore the deeper levels a heterosexual relationship can go to, let alone the complicated problems relationships often develop.

Instead it’s just one woman after another, just as in a porn film.

Anyway, this passage at the end of the book discards all the womanising and sensual rhetoric, and returns to much more abstract discussions between the two friends about art and religion.

There’s a lovely passage where, after a good long time of working on it (with a young boy assistant he’s been given, Erich) Goldmund shows his carving to Narziss, and it prompts the older man to a wonderfully insightful speculation about the intellectual and the artistic routes to God.

He mulls over how the intellectual personality strains to clear away all the clutter of the world in order to strive for the simplest, purest, most fundamental truths – while the artist throws him or herself into the things of the world, precisely into all the clutter, and, by dint of his or her passion, reveals beneath it the pattern underlying the world’s profusion.

‘I see you by the opposite way, the way which leads through the sense, reach as deep a knowledge as any that most thinkers achieve, of the essence and secret of our being, and a far more living mode of setting it forth.’ (Narziss addressing Goldmund, p.280)

This passage is worth rereading and savouring, as many passages of the book are, for example the couple of pages where Goldmund sits by the river, watching its ever-changing surface and pondering the nature of manmade beauty contrasted with the ever-fleeting beauty of the natural world.

Briefer but just as full of juice and wisdom is the passage where Narziss instructs Goldmund how to pray.

But, says the younger man, my mind is overwhelmed with doubts, about whether my prayers can ever be heard by a God who probably doesn’t exist and, even if he does, probably doesn’t hear them.

To which Narziss replies, imagine you’re singing a song. You don’t let yourself get swamped with doubts about whether you’re doing a good rendition or whether the composer would be upset by your voice or whether anyone’s listening properly and so on. You abandon yourself to the song. You give it your best shot. Singing is its own justification. Same with prayer.

I can see why Hesse inspires such loyalty among his devotees. He discusses serious problems with seriousness, he isn’t patronising or ironic, and his characters discuss ideas which occur to any educated person clearly and simply, and sometimes, with a depth of feeling or insight which clearly derive from the author’s lifelong engagement with these ideas.

And the depth and seriousness leave their mark on the reader. Some of these passages are really stirring.

Goldmund hits the road again

But all good things come to an end. It takes Goldmund two years to carve the wooden relief and when it is finally done, and installed on the steps and pulpit, he returns to his workshop and feels empty and spent.

He begins another work, a statue of the Mother of God, but goes absent for long walks in the country, feeling increasingly restless. He encounters a young peasant woman, Francisca, but is struck that, although he uses all his old tricks and tells her romantic tales of life on the road etc, she listens politely as to an old man, as to her father. Ah. He is old.

Back in the monastery, Goldmund realises he has grey in his hair and wrinkles round his eyes but more than that, he feels old.

So he leaves the monastery. With Narziss’s blessing he departs, leaving the narrative to describe Narziss’s sudden sense of emptiness. Narziss admires the way Goldmund’s wastrel, vagabond life has made him capable of creating such exquisite carvings which will bespeak the glory of God and his creation long after Narziss and his dry, scholarly theology is forgotten.

Goldmund returns, a broken man

Inevitably, Goldmund returns, in the autumn of the same year, but much changed, transfigured. Now he is an ill old man and Erich his assistant is appalled to see him, help him back into the workshop and put him to bed. After some days, Narziss comes to see him and is also appalled. Now Goldmund is grey-haired and sick, he has broken ribs and internal injuries.

As his health fails, Goldmund tells Narziss what happened. Turns out his real motivation to leave was not a general romantic urge to hit the road, but that he’d heard that Lady Agnes was in the area with Count Heinrich. Improbably, Goldmund had managed to secure an audience with her, but the Lady told him to his face that he is no longer the golden youth, the blonde sex god, that he was – and she turns away, uninterested.

Heartbroken, Goldmund rides off and doesn’t mind when his horse stumbles and throws him down into a gulley. He lands hard in a stream, breaks some ribs and lies all night in the freezing mountain water. Next day he staggers up and on and eventually is found and placed in a hospice, where he stays for months, sells the horse, uses up the money Narziss gave him and eventually realises he had to stagger back to Mariabronn.

Here Goldmund dies. On his deathbed, he says he is not afraid of death. In what we now realise was the great defining conversation of their youths, when Narziss had identified the central pillar of his personality as being the absence of his mother. Goldmund says that Narziss had given back his mother, restored the image of his mother to the central place in his life.

Now the pains in his chest feel not like the broken ribs and infections, but as if his mother, his beloved mother, the earth mother Eve, is putting her fingers between his ribs and pulling out his heart, taking it to her. For only with a mother can you die. ‘How can anyone love without a mother, and how can we die without a mother?’

And on these last words and their rather shocking image, Goldmund dies, leaving Narziss distraught.


I’m caught between two views, as I am with all the Hesse I’ve read.

Against

With my hard hat on, I know it is romantic twaddle. By that I mean that every scene is lit with a sentimental romantic light, and profoundly unrealistic.

1. Painless vagabonding Take the way he survives as a vagabond, with no food or money, and travelling across north Europe in the winter, for not weeks, or months, but years on end. I know people did do this, but a lot of them died of starvation and exposure. After a week sleeping rough in a forest, with no food and no blankets or bedding you would be in very poor shape, more a J.G. Ballard character at the end of their tether than a handsome swain.

2. Women everywhere Whereas Goldmund is always in such tip-top condition that, wherever he goes, every woman that he meets – virgin or housewife – throws themselves at him, and he ploughs his way through hundreds and hundreds of women.

3. The dialogue And then there’s the diction, the sub-Tennysonian melliflous fake medievalism, all palfreys and pilgrims, varlets and churls, like scenes from a thousand pre-Raphaelite paintings. As a tiny instance take the moment when Goldmund speaks to the haughty, high-born lady by the ivy-covered town wall, and offers his devotion:

‘Oh’, he replied, ‘I would as lief make you a gift as take one. It is myself I would offer you fair woman, and then you shall do as you will with me.’ (p.231)

It is all written in this style.

4. Lucky And the way he keeps landing on his feet – in the castle of the knight who needs a Latin scholar, in the household of the Master artist Nicholas – is more like a fable or fairy tale than an adult narrative.

5. Sex And the way there always just happens to be a nubile and beautiful young woman in the offing for him to seduce, fondle, strip and make love to… is more like a 1970s soft porn movie than reality.

Gently he unclasped the white fur at her neck and unsheathed her body. (p.234)

Indeed, the entirety of Goldmund’s adventures could be devastatingly critiqued as a sustained example of male wish-fulfilment, as the most basic sexist fantasy that more or less every women you meet is ready and willing to have sex with you, at no more than a smile and a wink.

None of the women appear to have periods or any other medical problems or difficulties. And nobody in this dreamworld appears to have a sexually transmitted disease.

6. Death as romantic And take the fundamentally romantic notion that Death is somehow romantic, seductive and sensual, a warm loving mother luring you into her bosomy embrace – an image which emerges in the plague scenes and recurs at the end.

‘I’m curious to die because it’s still my belief, or my dream, that I’m on my way back to my mother; because I hope my death will be a great happiness – as great as I had of my first woman. I can never rid myself of the thought that, instead of death with his sickle, it will be my mother who takes me into herself again, and leads me back into nothingness and innocence.’ (Goldmund, p.297)

Twaddle. Having seen death up close, I found absolutely nothing redeeming or good about it at all. It is the grief-stricken cessation of life. The sensual penumbra Hesse casts over it is late-romantic, 1890s sentimentality.

For

On the other hand… although the plots which deliver them up may be questionable, the intensity with which Hesse describes the emotional and sexual entanglements, especially the menage a trois at the knight’s castle, are conceived and described with an intense sensuality which really goes home to your imagination, reminding you of the best and most sensual experiences in your own life.

Similarly, the vagabonding is to be taken with a pinch of salt: it’s a narrative framework, a scaffolding, an age-old narrative trope designed to deliver a steady stream of situations which allow Goldmund/Hesse to meditate on the meaning of life, and death, of art and suffering, as he encounters and observes them.

And although he may not have anything blindingly original to say about these subjects, nonetheless reading a Hesse book means that you engage with these questions in a sustained and serious way for several days, through the medium of his lyrical and measured prose. And this can turn out to be a very moving and thought-provoking experience.

And because the characters in the books cover quite a range of topics, chances are that some, at least, of the subjects will touch a chord. For me it was the entire sequence with the Master carver and in particular the scene where Goldmund sits by the river and mulls over why some art may be technically finished and immaculate but doesn’t move you, whereas other, less finished works, for some reason touch your soul.

Conclusion

The hokiness of the plot, and the often sentimental romanticism of the worldview, and the questionable womanising, are all forgiveable because the book delivers a steady stream of deeply pondered thinking on a range of perennial topics.

German history

The Diversity of Life by E.O. Wilson (1992)

It is a failing of our species that we ignore and even despise the creatures whose lives sustain our own. (p.294)

Edward Osborne Wilson was born in 1929 and pursued a long career in biology, specialising in myrmecology, the study of ants, about which he came to be considered the world’s leading expert, and about which he published a massive textbook as well as countless research papers.

As well as his specialist scientific writing, Wilson has also published a series of (sometimes controversial) books about human nature, on collaborative species of animal (which led him to conceive the controversial theory of sociobiology), and about ecology and the environment.

(They’re controversial because he considers humans as just another complex life form, whose behaviour is dictated almost entirely by genetics and environment, discounting our ability to learn or change: beliefs which are opposed by liberals and progressives who believe humans can be transformed by education and culture.)

The Diversity of Life was an attempt to give an encyclopedic overview of life on earth – the myriads of life forms which create the dazzlingly complicated webs of life at all levels and in all parts of our planet – and then to inform the reader about the doleful devastation mankind is wreaking everywhere – and ends with some positive suggestions about how to try & save the environment, and the staggering diversity of life forms, before it’s too late.

The book is almost 30 years old but still so packed with information that maybe giving a synopsis of each chapter would be useful.


Part one – Violent nature, resilient life

1. Storm over the Amazon An impressionistic memoir of Wilson camping in the rainforest amid a tropical storm, which leads to musings about the phenomenal diversity of life forms in such places, and beyond, in all parts of the earth, from the Antarctic Ocean to deep sea, thermal vents.

2. Krakatau A vivid description of the eruption of Krakatoa leads into an account of how the sterile smoking stump of island left after the explosion was swiftly repopulated with all kinds of life forms within weeks of the catastrophe and now, 130 years later, is a completely repopulated tropical rainforest. Life survives and endures.

3. The Great Extinctions If the biggest volcanic explosion in recorded history can’t eliminate life, what can? Wilson explains the five big extinction events which the fossil record tells us about, when vast numbers of species were exterminated:

  • Ordovician 440 million years ago
  • Devonian 365 million years ago
  • Permian 245 million years ago
  • Triassic 210 million years ago
  • Cretaceous 66 million years ago

The last of these being the one which – supposedly – wiped out the dinosaurs, although Wilson points out that current knowledge suggests that dinosaur numbers were actually dropping off for millions of years before the actual ‘event’, whatever that was (most scientists think a massive meteor hit earth, a theory originally proposed by Luis Alvarez in 1980).

Anyway, the key thing is that the fossil record suggests that it took between five and 20 million years after each of these catastrophic events for the diversity of life to return to something like its pre-disaster levels.


Part two – Biodiversity rising

4. The Fundamental Unit A journey into evolutionary theory which quickly shows that many of its core concepts are deeply problematic and debated. Wilson clings to the notion of the species as the fundamental unit, because it makes sense of all biology –

A species is a population whose members are able to interbreed freely under natural conditions (p.36)

but concedes that other biologists give precedence to other concepts or levels of evolution, for example the population, the deme, or focus on genetics.

Which one you pick depends on your focus and priorities. The ‘species’ is a tricky concept to define, with the result that many biologists reach for subspecies (pp.58-61).

And that’s before you examine the record chronologically i.e. consider lineages of animals which we know stretch back for millions of years: at what point did one species slip into another? It depends. It depends what aspects you choose to focus on – DNA, or mating rituals, or wing length or diet or location.

The message is that the concepts of biology are precise and well-defined, but the real world is far more messy and complicated than, maybe, any human concepts can really fully capture.

5. New Species Wilson details all the processes by which new species have come about, introducing the concept of ‘intrinsic isolating mechanisms’, but going on to explain that these are endless. Almost any element in an environment, an organisms’s design or DNA might be an ‘isolating mechanism’, in the right circumstances. In other words, life forms are proliferating, mutating and changing constantly, all around us.

The possibility for error has no limit, and so intrinsic isolating mechanisms are endless in their variety. (p.51)

6. The forces of evolution Introduces us to a range of processes, operating at levels from genetics to entire populations, which drive evolutionary change, including:

  • genetic mutation
  • haploidy and diploidy (with an explanation of the cause of sickle-cell anaemia)
  • dominant and recessive genes
  • genotype (an individual’s collection of genes) and phenotype (the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment)
  • allometry (rates of growth of different parts of an organism)
  • microevolution (at the genetic level) and macroevolution (at the level of environment and population)
  • the theory of punctuated equilibrium proposed by Niles Eldredge and Stephen Jay Gould (that evolution happens in burst followed by long periods of no-change)
  • species selection

7. Adaptive radiation An explanation of the concepts of adaptive radiation and evolutionary convergence, taking in Hawaiian honeycreepers, Darwin’s finches on the Galapagos Islands, the cichlid fish of Lake Victoria, the astonishing diversity of shark species, and the Great American Interchange which followed when the rise of the Panama Isthmus joined previously separated North and South America 2.5 million years ago.

Ecological release = population increase that occurs when a species is freed from limiting factors in its environment.

Ecological constraint = constriction in the presence of a competitor.

8. The unexplored biosphere Describes our astonishing ignorance of how many species there are in the world. Wilson gives the total number of named species as 1.4 million, 751,000 of them insects, but the chapter goes on to explain our complete ignorance of the life forms in the ocean depths, or in the rainforest canopies, and the vast black hole of our ignorance of bacteria.

There could be anything between 10 million and 100 million species on earth – nobody knows.

He explains the hierarchy of toxonomy of living things: kingdom, phylum or division, class, order, family, genus, species.

Equitability = the distribution of diversity in a given location.

9. The creation of ecosystems Keystone species hold a system together e.g. sea otters on the California coast (which ate sea urchins thus preventing the sea urchins eating the kelp, so giving rise to forests of kelp which supported numerous life forms including whales who gave birth close to the forests of kelp) or elephants in the savannah (who, by pushing over trees, create diverse habitats).

Elasticity.

The predator paradox – in many systems it’s been shown that removing the top predator decreases diversity).

Character displacement. Symbiosis. The opposite of extinction is species packing.

The latitudinal diversity gradient i.e. there is more diversity in tropical rainforests – 30% of bird species, probably over half of all species, live in the rainforests – various theories why this should be (heat from the sun = energy + prolonged rain).

10. Biodiversity reaches the peak The reasons why biodiversity has steadily increased since the Cambrian explosion 550 million years ago, including the four main steps in life on earth:

  1. the origin of life from prebiotic organic molecules 3.9 billion years ago
  2. eukaryotic organisms 1.8 billion years ago
  3. the Cambrian explosion 540 to 500 million years ago
  4. the evolution of the human mind from 1 million to 100,000 years ago.

Why there is more diversity, the smaller the creatures/scale – because, at their scale, there are so many more niches to make a living in.


Part three – The human impact

It’s simple. We are destroying the world’s ecosystems, exterminating untold numbers of species before we can even identify them and any practical benefits they may have.

11. The life and death of species ‘Almost all the species that have ever lived are extinct, and yet more are alive today than at any time in the past (p.204)

How long do species survive? From 1 to 10 million years, depending on size and type. Then again, it’s likely that orchids which make up 8% of all known flowering plants, might speciate, thrive and die out far faster in the innumerable microsites which suit them in mountainous tropics.

The area effect = the rise of biodiversity according to island size (ten times the size, double the number of species). Large body size means smaller population and greater risk of extinction. The metapopulation concept of species existence.

12. Biodiversity threatened Extinctions by their very nature are rarely observed. Wilson devotes some pages to the thesis that wherever prehistoric man spread – in North America 8,000 years ago, in Australia 30,000 years ago, in the Pacific islands between 2,000 and 500 years ago – they exterminated all the large animals.

Obviously, since then Western settlers and colonists have been finishing off the job, and he gives depressing figures about numbers of bird, frog, tree and other species which have been exterminated in the past few hundred years by Western man, by colonists.

And now we are in a new era when exponentially growing populations of Third World countries are ravaging their own landscapes. He gives a list of 18 ‘hotspots’ (New Caledonia, Borneo, Ecuador) where half or more of the original rainforests has been heart-breakingly destroyed.

13. Unmined riches The idea that mankind should place a cash value on rainforests and other areas of diversity (coral reefs) in order to pay locals not to destroy them. Wilson gives the standard list of useful medicines and drugs we have discovered in remote and unexpected plants, wondering how many other useful, maybe life-saving substances are being trashed and destroyed before we ever have the chance to discover them.

But why  should this be? He explains that the millions of existing species have evolved through uncountable trillions of chemical interactions at all levels, in uncountably vast types of locations and settings – and so have been in effect a vast biochemical laboratory of life, infinitely huger, more complex, and going on for billions of years longer than our own feeble human laboratory efforts.

He gives practical examples of natural diversity and human narrowness:

  • the crops we grow are a handful – 20 or so – of the tens of thousands known, many of which are more productive, but just culturally alien
  • same with animals – we still farm the ten of so animals which Bronze Age man domesticated 10,000 years ago when there is a world of more productive animals e.g. the giant Amazon river turtle, the green iguana, which both produce far more meat per hectare and cost than beef cattle
  • why do we still fish wild in the seas, devastating entire ecosystems, when we could produce more fish more efficiently in controlled farms?
  • the absolutely vital importance of maintaining wild stocks and varieties of species we grow for food:
    • when in the 1970s the grassy-stunt virus devastated rice crops it was only the lucky chance that a remote Indian rice species contained genes which granted immunity to the virus and so could be cross-bred with commercial varieties which saved the world’s rice
    • it was only because wild varieties of coffee still grew in Ethiopia that genes could be isolated from them and cross-bred into commercial coffee crops in Latin America which saved them from devastation by ‘coffee rust’
  • wipe out the rainforests and other hotspots of diversity, and there go your fallback species

14. Resolution As ‘the human juggernaut’ staggers on, destroying all in its path, what is to be done? Wilson suggests a list:

  1. Survey the world’s flora and fauna – an epic task, particularly as there are maybe only 1,500 scientists in the whole world qualified to do it
  2. Create biological wealth – via ‘chemical prospecting’ i.e. looking for chemicals produced by organisms which might have practical applications (he gives a list of such discoveries)
  3. Promote sustainable development – for example strip logging to replace slash and burn, with numerous examples
  4. Wilson critiques the arguments for
    • cryogenically freezing species
    • seed banks
    • zoos
  5. They can only save a tiny fraction of species, and then only a handful of samples – but the key factor is that all organisms can only exist in fantastically complicated ecosystems, which no freezing or zoosor seed banks can preserve. There is no alternative to complete preservation of existing wilderness

15. The environmental ethic A final summing up. We are living through the sixth great extinction. Between a tenth and a quarter of all the world’s species will be wiped out in the next 50 years.

Having dispensed with the ad hoc and limited attempts at salvage outlined above, Wilson concludes that the only viable way to maintain even a fraction of the world’s biodiversity is to identify the world’s biodiversity ‘hot spots’ and preserve the entire ecosystems.

Each ecosystem has intrinsic value (p.148)

In the last few pages he makes the ‘deepest’ plea for conservation based on what he calls biophilia – this is that there is all kinds of evidence that humans need nature: we were produced over 2 million years of evolution and are descended from animals which themselves have encoded in the genes for their brains and nervous systems all kinds of interactions with the environment, with sun and moon, and rain and heat, and water and food, with rustling grasses and sheltering trees.

The most basic reason for making heroic efforts to preserve biodiversity is that at a really fundamental level, we need it to carry on feeling human.

On planet, one experiment (p.170)


Conclusion

Obviously, I know human beings are destroying the planet and exterminating other species at an unprecedented rate. Everyone who can read a newspaper or watch TV should know that by now, so the message of his book was over-familiar and sad.

But it was lovely to read again several passages whose imaginative brio had haunted me ever since I first read this book back in 1994:

  • the opening rich and impressionistic description of the rainforest
  • a gripping couple of pages at the start of chapter five where he describes what it would be like to set off at walking pace from the centre of the earth outwards, across the burning core, then into the cooler mantle and so on, suddenly emerging through topsoil into the air and walking through the extraordinary concentration of billions of life forms in a few minutes – we are that thin a layer on the surface of this spinning, hurtling planet
  • the couple of pages about sharks, whose weird diversity still astonishes
  • the brisk, no-nonsense account of how ‘native’ peoples or First Peoples were no tender-hearted environmentalists but hunted to death all the large megafauna wherever they spread
  • the dazzling description of all the organisms which are found in just one pinch of topsoil

As to the message, that we must try and preserve the diversity of life and respect the delicate ecosystems on which our existence ultimately depends – well, that seems to have been soundly ignored more or less everywhere, over the past thirty years since the book was published.

What Is Life? How Chemistry Becomes Biology by Addy Pross (2012)

I will attempt to show that the chasm separating biology and chemistry is bridgeable, that Darwinian theory can be integrated into a more general chemical theory of matter, and that biology is just chemistry, or to be more precise, a sub-branch of chemistry – replicative chemistry. (p.122)

Repetitive and prolix

This book is 190 pages long. It is much harder to read than it need be because Pross is a bad writer with very bad habits, namely 1. irritating repetition and 2. harking back and forward. The initial point which he repeats again and again in the first 120 pages is that nobody knows the secret of the origins of life and all previous attempts to solve it have been dead ends.

So, what can we conclude regarding the emergence of life on our planet? The short answer: almost nothing. (p.109)

We don’t know how to go about making life because we don’t really know what life is, and we don’t know what life is, because we don’t understand the principles that led to its emergence. (p.111)

The efforts to uncover probiotic-type chemistry, while of considerable interest in their own right, were never likely to lead us to the ultimate goal – understanding how life on earth emerged. (p.99)

Well, at the time of writing, the so-called Holy Grail (the Human Genome sequence) and the language of life that it was supposed to have taught us have not delivered the promised goods. (p.114)

But the systems biology approach has not proved a nirvana… (p.116)

Non-equilibrium thermodynamics has not proved to be the hoped-for breakthrough in seeking greater understanding of biological complexity. (p.119)

A physically based theory of life continues to elude us. (p.119)

While Conway’s Life game has opened up interesting insights into complex systems in general, direct insights into the nature of living systems do not appear to have been forthcoming. (p.120)

The book is so repetitive I though the author and his editor must have Alzheimer’s Disease. On page viii we are told that the physicist Erwin Schrödinger wrote a pithy little book titled What Is Life? which concluded that present-day physics and chemistry can’t explain the phenomenon of life. Then, on page xii, we’re told that the physicist Erwin Schrödinger’ found the issue highly troublesome’. Then on page 3 that the issue ‘certainly troubled the great physicists of the century, amongst them Bohr, Schrödinger and Wigner’. Then on page 36, we learn that:

Erwin Schrödinger, the father of quantum mechanics, whose provocative little book What Is Life? we mentioned earlier, was particularly puzzled by life’s strange thermodynamic behaviour.

When it comes to Darwin we are told on page 8 that:

Darwin himself explicitly avoided the origin of life question, recognising that within the existing state of knowledge the question was premature.

and then, in case we have senile dementia or the memory of a goldfish, on page 35 he tells us that:

Darwin deliberately side-stepped the challenge, recognising that it could not be adequately addressed within the existing state of knowledge.

As to the harking back and forth, Pross is one of those writers who is continually telling you he’s going to tell you something, and then continually reminding you that he told you something back in chapter 2 or chapter 4 – but nowhere in the reading process do you actually get clearly stated the damn thing he claims to be telling.

As we mentioned in chapter 4…

As noted above…

I will say more on this point subsequently…

We will consider a possible resolution of this sticky problem in chapter 7…

As discussed in chapter 5… as we will shortly see… As we have already pointed out… As we have discussed in some detail in chapter 5…  described in detail in chapter 4…

In this chapter I will describe… In this chapter I will attempt…

I will defer this aspect of the discussion until chapter 8…

Jam yesterday, jam tomorrow, but never jam today.

Shallow philosophy

It is a philosophy book written by a chemist. As such it comes over as extremely shallow and amateurish. Pross namechecks Wittgenstein, and (pointlessly) tells us that ‘tractatus’ is Latin for ‘treatise’ (p.48) – but fails to understand or engage with Wittgenstein’s thought.

My heart sank when I came to chapter 3, titled Understanding ‘understanding’ which boils down to a superficial consideration of the difference between a ‘reductionist’ and a ‘holistic’ approach to science, the general idea that science is based on reductionism i.e. reducing systems to their smallest parts and understanding their functioning before slowly building up in scale, whereas ‘holistic’ approach tries to look at the entire system in the round. Pross gives a brief superficial overview of the two approaches before concluding that neither one gets us any closer to an answer.

Instead of interesting examples from chemistry, shallow examples from ‘philosophy’

Even more irritating than the repetition is the nature of the examples. I thought this would be a book about chemistry but it isn’t. Pross thinks he is writing a philosophical examination of the meaning of life, and so the book is stuffed with the kind of fake everyday examples which philosophers use and which are a) deeply patronising b) deeply uninformative.

Thus on page x of the introduction Pross says imagine you’re walking through a field and you come across a refrigerator. He then gives two pages explaining how a refrigerator works and saying that you, coming across a fully functional refrigerator in the middle of a field, is about as probable as the purposeful and complex forms of life can have come about by accident.

Then he writes, Imagine that you get into a motor car. We only dare drive around among ‘an endless stream of vehicular metal’ on the assumption that the other drivers have purpose and intention and will stick to the laws of the highway code.

On page 20 he introduces us to the idea of a ‘clock’ and explains how a clock is an intricate mechanism made of numerous beautifully engineered parts but it will eventually break down. But a living organism on the other hand, can repair itself.

Then he says imagine you’re walking down the street and you bump into an old friend named Bill. He looks like Bill, he talks like Bill and yet – did you know that virtually every cell in Bill’s body has renewed itself since last time you saw him, because life forms have this wonderful ability to repair and renew themselves!

Later, he explains how a Boeing 747 didn’t come into existence spontaneously, but was developed from earlier plane designs, all ultimately stemming from the Wright brothers’ first lighter than air flying machine.

You see how all these examples are a) trite b) patronising c) don’t tell you anything at all about the chemistry of life.

He tells us that if you drop a rock out the window, it falls to the ground. And yet a bird can hover in the air merely by flapping its wings! For some reason it is able to resist the Second law of Thermodynamics! How? Why? Nobody knows!

Deliberately superficial

And when he does get around to explaining anything, Pross himself admits that he is doing it in a trivial, hurried, quick, sketchy way and leaving out most of the details.

I will spare the reader a detailed discussion…

These ideas were discussed with some enthusiasm some 20-30 years ago and without going into further detail…

If that sounds too mathematical, let’s explain the difference by recounting the classical legend of the Chinese emperor who was saved in battle by a peasant farmer. (p.64)

Only in the latter pages – only when he gets to propound his own theory from about page 130 – do you realise that he is not so much making a logical point as trying to get you to see the problem from an entirely new perspective. A little like seeing the world from the Marxist or the Freudian point of view, Pross believes himself to be in possession of an utterly new way of thinking which realigns all previous study and research and thinking on the subject. It is so far-ranging and wide-sweeping that it cannot be told consecutively.

And it’s this which explains the irritating sense of repetition and circling and his constant harking forward to things he’s going to tell you, and then harking back to things he claims to have explained a few chapters earlier. The first 130 pages are like being lost in a maze.

The problem of the origin of life

People have been wondering about the special quality of live things as opposed to dead things for as long as there have been people. Darwin discovered the basis of all modern thinking about life forms, which is the theory of evolution by natural selection. But he shied away from speculating on how life first came about.

Pross – in a typically roundabout manner – lists the ‘problems’ facing anyone trying to answer the question, What is life and how did it begin?

  • life breaks the second law of thermodynamics i.e. appears to create order out of chaos, as opposed to the Law which says everything tends in the opposite direction i.e. tends towards entropy
  • life can be partly defined by its sends of purpose: quite clearly inanimate objects do not have this
  • life is complex
  • life is organised

Put another way, why is biology so different from chemistry? How are the inert reactions of chemistry different from the purposive reactions of life? He sums this up in a diagram which appears several times:

He divides the move from non-life into complex life into two phases. The chemical phase covers the move from non-life to simple life, the biological phase covers the move from simple life to complex life. Now, we know that the biological phase is covered by the iron rules of Darwinian evolution – but what triggered, and how can we account for, the move from non-life to simple life? Hence a big ?

Pross’s solution

Then, on page 127, Pross finally introduces his Big Idea and spends the final fifty or so pages of the book showing how his theory addresses all the problem in existing ‘origin of life’ literature.

His idea begins with the established knowledge that all chemical reactions seek out the most ‘stable’ format.

He introduces us to the notion that chemists actually have several working definitions of ‘stability’, and then introduces us to a new one: the notion of dynamic kinetic stability, or DKS.

He describes experiments by Sol Spiegelman in the 1980s into RNA. This showed how the RNA molecule replicated itself outside of a living cell. That was the most important conclusion of the experiment. But they also found that the RNA molecules replicated but also span off mutations, generally small strands of of RNA, some of which metabolised the nutrients far quicker than earlier varieties. These grew at an exponential rate to swiftly fill the petri dishes and push the longer, ‘correct’ RNA to extinction.

For Pross what Spiegelman’s experiments showed was that inorganic dead chemicals can a) replicate b) replicate at exponential speed until they have established a situation of dynamic kinetic stability. He then goes on to equate his concept of dynamic kinetic stability with the Darwinian one of ‘fitness’. Famously, it is the ‘fit’ which triumph in the never-ending battle for existence. Well, Pross says this concept can be rethought of as, the population which achieves greatest dynamic kinetic stability – which replicates fast enough and widely enough – will survive, will be the fittest.

fitness = dynamic kinetic stability (p.141)

Thus Darwin’s ideas about the eternal struggle for existence and the survival of the fittest can be extended into non-organic chemistry, but in a particular and special way:

Just as in the ‘regular’ chemical world the drive of all physical and chemical systems is toward the most stable state, in the replicative world the drive is also toward the most stable state, but of the kind of stability applicable within that replicative world, DKS. (p.155)

Another way of looking at all this is via the Second Law. The Second Law of Thermodynamics has universally been interpreted as militating against life. Life is an affront to the Law, which says that all energy dissipates and seeks out the state of maximum diffusion. Entropy always triumphs. But not in life. How? Why?

But Pross says that, if molecules like his are capable of mutating and evolving – as the Sol Spiegelman experiments suggest – then they only appear to contradict the Second Law. In actual fact they are functioning in what Pross now declares is an entirely different realm of chemistry (and physics). The RNA replicating molecules are functioning in the realm of replicative chemistry. They are still inorganic, ‘dead’ molecules – but they replicate quickly, mutate to find the most efficient variants, and reproduce quickly towards a state of dynamic kinetic stability.

So what he’s trying to do is show how it is possible for long complex molecules which are utterly ‘dead’, nonetheless to behave in a manner which begins to see them displaying qualities more associated with the realm of biology:

  • ‘reproduction’ with errors
  • triumph of the fittest
  • apparent ‘purpose’
  • the ability to become more complex

None of this is caused by any magical ‘life force’ or divine intervention (the two bogeymen of life scientists), but purely as a result of the blind materialistic forces driving them to take most advantage of their environment i.e. use up all its nutrients.

Pross now takes us back to that two-step diagram of how life came about, shown above – Non-Life to Simple Life, Simple Life to Complex Life, labelled the Chemical Phase and the Biological Phase, respectively.

He recaps how the second phase – how simple life evolves greater complexity – can be explained using Darwin’s theory of evolution by natural selection: even the most primitive life forms will replicate until they reach the limits of the available food sources, at which point any mutation leading to even a fractional differentiation in the efficiency of processing food will give the more advanced variants an advantage. The rest is the three billion year history of life on earth.

It is phase one – the step from non-life to life – which Pross has (repeatedly) explained has given many of the cleverest biologists, physicists and chemists of the 20th century sleepless nights, and which – in chapters 3 and 4 – he runs through the various theories or approaches which have failed to deliver an answer to.

Well, Pross’s bombshell solution is simple. There are not two steps – there was only ever one step. The Darwinian mechanism by which the best adapted entity wins out in a given situation applies to inert chemicals as much as to life forms.

Let me now drop the bombshell… The so-called two-stage process is not two-stage at all. It is really just once, continuous process. (p.127) … what is termed natural selection within the biological world is also found to operate in the chemical world… (p.128)

Pross recaps the findings of that Spiegelman experiment, which was that the RNA molecules eventually made errors in their replication, and some of the erroneous molecules were more efficient at using up the nutrition in the test tube. After just a day, Spiegelman found the long RNA molecules – which took a long time to replicate – were being replaced by much shorter molecules which replicated much quicker.

There, in a nutshell, is Pross’s theory in action. Darwinian competition, previously thought to be restricted only to living organisms, can be shown to apply to inorganic molecules as well – because inorganic molecules themselves show replicating, ‘competitive’ behaviour.

For Pross this insight was confirmed in experiments conducted by Gerald Joyce in 2009, who showed that a variety of types of RNA, placed in a nutrient, replicated in such a way as to establish a kind of dynamic equilibrium, where each molecule established a chemical niche and thrived on some of the nutrients, while other RNA varieties evolved to thrive on other types. To summarise:

The processes of abiogenesis and evolution are actually one physicochemical process governed by one single mechanism, rather than two discrete processes governed by two different mechanisms. (p.136)

Or:

The study of simple replicating systems has revealed an extraordinary connection – that Darwinian theory, that quintessential biological principle, can be incorporated into a more general chemical theory of evolution, one that encompasses both living and non-living systems. it is that integration that forms the basis of the theory of life I propose. (p.162)

The remaining 50 or so pages work through the implications of this idea or perspective. For example he redefines the Darwinian notion of ‘fitness’ to be ‘dynamic kinetic stability’. In other words, the biological concept of ‘fitness’ turns out, in his theory, to be merely the biological expression of a ‘more general and fundamental chemical concept’ (p.141).

He works through a number of what are traditionally taken to be life’s attributes and reinterprets in the new terms he’s introduced, in terms of dynamic kinetic stability, replicative chemistry and so on. Thus he addresses life’s complexity, life’s instability, life’s dynamic nature, life’s diversity, life’s homochirality, life’s teleonomic character, the nature of consciousness, and speculating about what alien life would look like before summing up his theory. Again.

A solution to the primary question exists and is breathtakingly simple: life on earth emerged through the enormous kinetic power of the replication reaction acting on unidentified, but simple replicating systems, apparently composed of chain-like oligomeric substances, RNA or RNA-like, capable of mutation and complexification. That process of complexification took place because it resulted in the enhancement of their stability – not their thermodynamic stability, but rather the relevant stability in the world of replicating systems, their DKS. (p.183)

A thought about the second law

Pross has explained that the Second Law of Thermodynamics apparently militates against the spontaneous generation of life, in any form, because life is organised and the second law says everything tends towards chaos. But he comes up with an ingenious solution. If one of these hypothetical early replicating molecules acquired the ability to generate energy from light – it would effectively bypass the second law. It would acquire energy from outside the ‘system’ in which it is supposedly confined and in which entropy prevails.

The existence of an energy-gathering capacity within a replicating entity effectively ‘frees’ that entity from the constraints of the Second Law in much the same way that a car engine ‘free’s a car from gravitational constrains. (p.157)

This insight shed light on an old problem, and on a fragment of the overall issue – but it isn’t enough by itself to justify his theory.

Thoughts

Several times I nearly threw away the book in my frustration before finally arriving at the Eureka moment about page 130. From there onwards it does become a lot better. As you read Pross you have the sense of a whole new perspective opening up on this notorious issue.

However, as with all these theories, you can’t help thinking that if his theory had been at all accepted by the scientific community – then you’d have heard about it by now.

If his theory really does finally solve the Great Mystery of Life which all the greatest minds of humanity have laboured over for millennia… surely it would be a bit better known, or widely accepted by his peers?

The theory relies heavily on results from Sol Spiegelman’s experiments with RNA in the 1980s. Mightn’t Spiegelman himself, or other tens of thousands of other biologists, have noticed its implications in the thirty odd years between the experiments and Pross’s book?

And if Pross has solved the problem of the origin of life, how come so many other, presumably well-informed and highly educated scientists, are still researching the ‘problem’?

(By the way, the Harvard website optimistically declares that:

Thanks to advances in technologies in these areas, answers to some of the compelling questions surrounding the origins of life in the universe were now possibly within reach… Today a larger team of researchers have joined this exciting biochemical ‘journey through the Universe’ to unravel one of humankind’s most compelling mysteries – the origins of life in the Universe.

Possibly within reach’, lol. Good times are always just around the corner in the origins-of-life industry.)

So I admit to being interested by pages 130 onwards of his book, gripped by the urgency with which he tells his story, gripped by the vehemence of his presentation, in the same way you’d be gripped by a thriller while you read it. But then you put it down and forget about it, going back to your everyday life. Same here.

It’s hard because it is difficult to keep in mind Pross’s slender chain of argumentation. It rests on the two-stage diagram – on Pross’s own interpretation of the Spiegelman experiments – on his special idea of dynamic kinetic stability – and on the idea of replicative chemistry.

All of these require looking at the problem through is lens, from his perspective – for example agreeing with the idea that the complex problem of the origin of life can be boiled down to that two-stage diagram; this is done so that we can then watch him pull the rabbit out of the hat by saying it needn’t be in two stages after all! So he’s address the problem of the diagram. But it is, after all, just one simplistic diagram.

Same with his redefining Darwin’s notion of ‘fitness’ as being identical to his notion of dynamic kinetic stability. Well, if he says so. but in science you have to get other scientists to agree with you, preferably by offering tangible proof.

These are more like tricks of perspective than a substantial new theory. And this comes back to his rhetorical strategy of repetition, to the harping on the same ideas.

The book argues its case less with evidence (there is, in the end, very little scientific ‘evidence’ for his theory – precisely two experiments, as far as I can see), but more by presenting a raft of ideas in their current accepted form (for 130 boring pages), and then trying to persuade you to see them all anew, through his eyes, from his perspective (in the final 50 pages). As he summarises it (yet again) on page 162:

The emergence of life was initiated by the emergence of a single replicating system, because that seemingly inconsequentual event opened the door to a distinctly different kind of chemistry – replicative chemistry. Entering the world of replicative chemistry reveals the existence of that other kind of stability in nature, the dynamic kinetic stability of things that are good at making more of themselves.Exploring the world of replicative chemistry helps explain why a simple primordial replicating system would have been expected to complexify over time. The reason: to increase its stability – its dynamic kinetic stability (DKS).

Note the phrase’ entering the world of replicative chemistry…’ – It sounds a little like ‘entering the world of Narnia’. It is almost as if he’s describing a religious conversion. All the facts remain the same, but new acolytes now see them in a totally different light.

Life then is just the chemical consequences that derive from the power of exponential growth operating on certain replicating chemical systems. (p.164)

(I am quoting Pross at length because I don’t want to sell his ideas short; I want to convey them as accurately as possible, and in his own words.)

Or, as he puts it again a few pages later (you see how his argument proceeds by, or certainly involves a lot of, repetition):

Life then is just a highly intricate network of chemical reactions that has maintained its autocatalytic capability, and, as already noted, that complex network emerged one step at a time starting from simpler netowrks. And the driving force? As discussed in earlier chapter, it is the drive toward greater DKS, itself based on the kinetic power of replication, which allows replicating chemical systems to develop into ever-increasing complex and stable forms. (p.185)

It’s all reasonably persuasive when you’re reading the last third of his book – but oddly forgettable once you put it down.

Fascinating facts and tasty terminology

Along the way, the reader picks up a number of interesting ideas.

  • Panspermia – the theory that life exists throughout the universe and can be carried on meteors, comets etc, and one of these landed and seeded life on earth
  • every adult human is made up of some ten thousand billion cells; but we harbour in our guts and all over the surface of our bodies ten times as many – one hundred thousand bacteria. In an adult body hundreds of billions of new cells are created daily in order to replace the ones that die on a daily basis
  • in 2017 it was estimated there may be as many as two billion species of bacteria on earth
  • the Principle of Divergence – many different species are generated from a few sources
  • teleonomy – the quality of apparent purposefulness and goal-directedness of structures and functions in living organisms
  • chiral – an adjective meaning a molecule’s mirror image is not superimposable upon the molecule itself: in fact molecules often come in mirror-image formations, known as left and right-handed
  • racemic – a racemic mixture, or racemate, is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule.
  • reductionist – analysing and describing a complex phenomenon in terms of its simple or fundamental constituents
  • holistic – the belief that the parts of something are intimately interconnected and explicable only by reference to the whole
  • Second Law of Thermodynamics – ‘in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state.’ This is also commonly referred to as entropy
  • the thermodynamic consideration – chemical reactions will only take place if the reaction products are of lower free energy than the reactants
  • catalyst – a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
  • catalytic – requires an external catalyst to spark a chemical reaction
  • auocatalytic – a reaction which catalyses itself
  • cross-catalysis – two chemicals trigger reactions in each other
  • static stability – water, left to itself, is a stable chemical compound
  • dynamic stability – a river is always a river even though it is continually changing
  • prebiotic earth – earth before life
  • abiogenesis – the process whereby life was derived from non-living chemicals
  • systems chemistry – the chemical reactions of replicating molecules and the networks they create
  • the competitive exclusion principle – complete competitors cannot co-exist, or, Ecological differentiation is th enecessary condition for co-existence

Does anyone care?

Pross thinks the fact that biologists and biochemists can’t account for the difference between complex but inanimate molecules, and the simplest actual forms of life – bacteria – is a Very Important Problem. He thinks that:

Until the deep conceptual chasm that continues to separate living and non-living is bridged, until the two sciences – physics and biology – can merge naturally, the nature of life, and hence man’s place in the universe, will continue to remain gnawingly uncertain. (p.42)

‘Gnawingly’. Do you feel the uncertainty about whetherbiology and physics can be naturally merged is gnawing away at you? Or, as he puts it in his opening sentences:

The subject of this book addresses basic questions that have transfixed and tormented humankind for millennia, ever since we sought to better understand our place in the universe – the nature of living things and their relationship to the non-living. The importance of finding a definitive answer to these questions cannot be overstated – it would reveal to us not just who and what we are, but would impact on our understanding of the universe as a whole. (p.viii)

I immediately disagreed. ‘The importance of finding a definitive answer to these questions cannot be overstated’? Yes it can. Maybe, just maybe – it is not very important at all.

What do we mean by ‘important’, anyway? Is it important to you, reading this review, to realise that the division between the initial, chemical phase of the origin of life and the secondary, biological phase, is in fact a delusion, and that both processes can be accounted for by applying Darwinian selection to supposedly inorganic chemicals?

If you tried to tell your friends and family 1. how easy would you find it to explain? 2. would you seriously expect anyone to care?

Isn’t it, in fact, more likely that the laws or rules or theories about how life arose from inanimate matter are likely to be so technical, so specialised and so hedged around with qualifications, that only highly trained experts can really understand them?

Maybe Pross has squared the circle and produced a feasible explanation of the origins of life on earth. Maybe this book really is – The Answer! But in which case – why hasn’t everything changed, why hasn’t the whole human race breathed a collective sigh of relief and said, NOW we understand how it all started, NOW we know what it all means, NOW I understand who I am and my place in the universe?

When I explained Pross’s theory, in some detail, to my long-suffering wife (who did a life sciences degree) she replied that, quite obviously chemistry and biology are related; anyone who’s studied biology knows it is based on chemistry. She hardly found it ‘an extraordinary connection’. When I raised it with my son, who is studying biology at university, he’d never heard of Pross or his theory.

So one’s final conclusion is that our understanding of ‘The nature of life, and hence man’s place in the universe’ has remained remarkably unchanged by this little book and will, in all likelihood, remain so.

Seven Clues to the Origin of Life by A.G. Cairns-Smith (1985)

The topic of the origin of life on the Earth is a branch of mineralogy. (p.99)

How did life begin? To be more precise, how did the inorganic chemicals formed in the early years of planet earth, on the molten rocks or in the salty sea or in the methane atmosphere, transform into ‘life’ – complex organisms which extract food from the environment and replicate, and from which all life forms today are ultimately descended? What, when and how was that first momentous step taken?

Thousands of biologists have devoted their careers to trying to answer this question, with the result that there are lots of speculative theories.

Alexander Graham Cairns-Smith (1931-2016) was an organic chemist and molecular biologist at the University of Glasgow, and this 120-page book was his attempt to answer the Big Question.

In a nutshell he suggested that life derived from self-replicating clay crystals. To use Wikipedia’s summary:

Clay minerals form naturally from silicates in solution. Clay crystals, like other crystals, preserve their external formal arrangement as they grow, snap, and grow further.

Clay crystal masses of a particular external form may happen to affect their environment in ways that affect their chances of further replication. For example, a ‘stickier’ clay crystal is more likely to silt up a stream bed, creating an environment conducive to further sedimentation.

It is conceivable that such effects could extend to the creation of flat areas likely to be exposed to air, dry, and turn to wind-borne dust, which could fall randomly in other streams.

Thus – by simple, inorganic, physical processes – a selection environment might exist for the reproduction of clay crystals of the ‘stickier’ shape.

Cairns-Smith’s book is densely argued, each chapter like a lecture or seminar packed with suggestive evidence about what we know about current life forms, a summary of the principles underlying Darwin’s theory of evolution, and about how we can slowly move backwards along the tree of life, speculating about how it developed.

But, as you can see from the summary above, in the end, it is just another educated guess.

Detective story

The blurb on the back and the introduction both claim the book is written in the style of a detective story. Oh no it isn’t. It is written in the style of a biology book – more precisely, a biology book which is looking at the underlying principles of life, the kind of abstract engineering principles underlying life – and all of these take quite some explaining, drawing in examples from molecular biology where required.

Sometimes (as in chapter 4 where he explains in detail how DNA and RNA and amino acids and proteins interact within a living cell) it becomes quite a demanding biology book.

What the author and publisher presumably mean is that, in attempt to sweeten the pill of a whole load of stuff about DNA and ribosomes, Cairns-Smith starts every chapter with a quote from a Sherlock Holmes story and from time to time claims to be pursuing his goal with Holmesian deduction.

You see Holmes, far from going for the easy bits first, would positively seek out those features in a case that were seemingly incomprehensible – ‘singular’ features he would call them… I think that the origin of life is a Holmesian problem. (p.ix)

Towards the very end, he remembers this metaphor and talks about ‘tracking down the suspect’ and ‘making an arrest’ (i.e. of the first gene machine, the origin of life). But this light dusting of Holmesiana doesn’t do much to conceal the sometimes quite demanding science, and the relentlessly pedagogical tone of the book.

Broad outline

1. Panspermia

First off, Cairns-Smith dismisses some of the other theories about the origin of life. He makes short work of the theories of Fred Hoyle and Francis Crick that organic life might have arrived on earth from outer space, carried in dust clouds or on meteors etc (Crick’s version of this was named ‘Panspermia’) . I agree with Cairns-Smith that all variations on this hypothesis just relocate the problem somewhere else, but don’t solve it.

Cairns-Smith states the problem in three really fundamental facts:

  1. There is life on earth
  2. All known living things are at root the same (using the same carbon-based energy-gathering and DAN-replicating biochemistry)
  3. All known living things are very complicated

2. The theory of chemical evolution

In his day (the 1970s and 80s) the theory of ‘chemical evolution’ was widely thought to address the origin of life problem. This stated that lot of the basic amino acids and sugars which we find in organisms are relatively simple and so might well have been created by accident in the great sloshing oceans and lakes of pre-life earth, and that they then – somehow – came together to make more complex molecules which – somehow – learned how to replicate.

But it’s precisely on the vagueness of that ‘somehow’ that Cairns-Smith jumps. The leap from a random soup of semi-amino acids washing round in a lake and the immensely detailed and complex machinery of life demonstrated by even a tiny living organism – he selects the bacterium Escherichia coli – is just too vast a cliff face to have been climbed at random, by accident. It’s like saying if you left a bunch of wires and bits of metal sloshing around in a lake long enough they would eventually make a MacBook Air.

Cairns-Smith zeroes in on four keys aspects of life on earth which help to disprove the ‘chemical evolution’ theory.

  1. Life forms are complex systems. It is the whole machine which makes sense of its components.
  2. The systems are highly interlocked: catalysts are needed to make proteins, but proteins are needed to make catalysts; nucleic acids are needed to make proteins, yet proteins are needed to make nucleic acids;
  3. Life forms are very complex.
  4. The system is governed by rules and conventions: the exact choice of the amino acid alphabet and the set of assignments of amino acid letters to nucleic acid words are examples.

3. The Miller-Urey experiments

Cairns-Smith then critiques the theory derived from the Miller-Urey experiments.

In 1953 a graduate student, Stanley Miller, and his professor, Harold Urey, performed an experiment that demonstrated how organic molecules could have spontaneously formed from inorganic precursors, under conditions like those posited by the Oparin-Haldane Hypothesis. The now-famous ‘Miller–Urey experiment’ used a highly reduced mixture of gases – methane, ammonia and hydrogen – to form basic organic monomers, such as amino acids. (Wikipedia)

Cairns-Smith spends four pages comprehensively demolishing this approach by showing that:

  1. the ultraviolet light its exponents claim could have helped synthesise organic molecules is in fact known to break covalent bonds and so degrade more than construct complex molecules
  2. regardless of light, most organic molecules are in fact very fragile and degrade easily unless kept in optimum conditions (i.e. inside a living cell)
  3. even if some organic molecules were created, organic chemists know only too well that there are hundreds of thousands of ways in which carbon, hydrogen, nitrogen and oxygen can combine, and most of them result in sticky sludges and tars in which nothing could ‘live’

So that:

  1. Only some of the molecules of life can be made this way
  2. Most of the molecules that would be made this way are emphatically not the ‘molecules of life’
  3. The ‘molecules of life’ are usually better made under conditions far most favourable than those obtaining back in the primordial soup era

He then does some back-of-a-matchbox calculations to speculate about how long it would take a random collection of organic molecules to ‘happen’ to all tumble together and create a life form: longer than the life of the universe, is his conclusion. No, this random approach won’t work.

Preliminary principles

Instead, he suggests a couple of principles of his own:

  1. That some and maybe all of the chemicals we now associate with ‘life’ were not present in the first replicating organisms; they came later; their exquisitely delicate interactivity suggests that they are the result not the cause of evolution
  2. Therefore, all lines of investigation which seek to account for the presence of the molecules of life are putting the cart before the horse: it isn’t the molecules which are important – it is the mechanism of replication with errors

Cairns-Smith thinks we should put the molecules of life question completely to one side, and instead seek for entirely inorganic systems which would replicate, with errors, so that the errors would be culled and more efficient ways of replicating tend to thrive on the available source material, beginning to create that dynamism and ‘sense of purpose’ which is one of life’s characteristics.

We keep coming to this idea that at some earlier phase of evolution, before life as we know it, there were other kinds of evolving system, other organisms that, in effect, invented our system. (p.61)

This seems, intuitively, like a more satisfying approach. Random forces will never make a MacBook Air and, as he has shown in chapter 4, even an entity like Escherichia coli is so staggeringly complex and amazingly finely-tuned as to be inconceivable as the product of chance.

Trying to show that complex molecules like ribosomes or RNA or amino acids – which rely on each other to be made and maintained, which cannot exist deprived of the intricately complicated interplay within each living cell – came about by chance is approaching the problem the wrong way. All these complex organic molecules must be the result of evolution. Evolution itself must have started with something much, much simpler – with the ‘invention’ of the basic engine, motor, the fundamental principle – and this is replication with errors. In other words:

Evolution started with ‘low-tech’ organisms that did not have to be, and probably were not made from, ‘the molecules of life’. (p.65)

Crystals

And it is at this point that Cairns-Smith introduces his Big Idea – the central role of clay crystals – in a chapter titled, unsurprisingly, ‘Crystals’ (pp.75-79).

He now explains in some detail the surprisingly complicated and varied world of clay crystals. These naturally form in various solutions and, if splashed up onto surfaces like rocks or stones, crystallise out into lattices, but the crystallisation process also commonly involves errors and mutations.

His description of the different types of crystals and their properties is fascinating – who knew there were so many types, shapes, patterns and processes, starting with an introduction to the processes of saturation and super-saturation. The point is that crystals naturally occur and naturally mutate. He lists the ways they can vary or diverge from their ‘pure’ forms: twinning, stacking errors, cation substitutions, growth in preferred directions, break-up along preferred planes (p.97).

There follows a chapter about the prevalence of crystals in mud and clay and, therefore, their widespread presence in the conditions of the early planet earth.

And then, finally, he explains the big leap whereby replicating crystals may have attracted to themselves other molecules.

There follows a process of natural selection for clay crystals that trap certain forms of molecules to their surfaces that may enhance their replication potential. Complex proto-organic molecules can be catalysed by the surface properties of silicates.

Genetic takeover of the crystals

It is at this point that he introduces the idea of a ‘genetic takeover’.

When complex molecules perform a ‘genetic takeover’ from their clay ‘vehicle’, they become an independent locus of replication – an evolutionary moment that might be understood as the first exaptation.

(Exaptation = ‘the process by which features acquire functions for which they were not originally adapted or selected’)

Cairns-Smith had already described this process – the ‘genetic takeover’ of an initial, non-organic process by more complex, potentially organic molecules – in his earlier, longer and far more technical book, Genetic Takeover: And the Mineral Origins of Life, published in 1982.

This book – the Seven Clues – is a much shorter, non-technical and more accessible popularisation of the earlier tome. Hence the frivolous references to Sherlock Holmes.

Proliferating crystals form the scaffold for molecules which learn to replicate without them

The final chapter explains how these very common and proliferating entities (clay crystals) might have formed into structures and arrangements which attracted – for purely chemical reasons – various elementary organic molecules to themselves.

Certain repeating structures might attract molecules which then build up into more complex molecules, into molecules which are more efficient at converting the energy of the sun into further molecular combinations. And thus the principle of replication with variation, and competition for resources among the various types of replicating molecule, would have been established.

Thoughts

At this point the book ends, his case presented. It has been a fascinating journey because a) it is interesting to learn about all the different shapes and types of clay crystal b) he forces the reader to think about the fundamental engineering and logistical aspects of life forms, to consider the underlying principles which must inform all life forms, which is challenging and rewarding.

But, even in his own terms, Cairns-Smith’s notion of more and more complex potentially organic molecules being haphazardly replicated on a framework of proliferating clay crystals is still a long, long, long way from even the most primitive life forms known to us, with their vastly complex structure of cell membrane, nucleus and internal sea awash with DNA-controlled biochemical processes.
