Dr Marx, Professor Childe and manure: some rather crude materialism
by Humphrey McQueen
Our text at this Evensong is taken from Deuteronomy, chapter 23, verses 13-14:
And thou shalt have a paddle upon thy weapon; and it shall be, when thou shalt ease thyself abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee:
For the LORD thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee; therefore shall thy camp be holy: that he see no unclean thing in thee, and turn away from thee.
I am relieved to see that you were not turned away by the crude title of this talk.
The combining of ‘materialism’, ‘crude’ and ‘manure’ is polite. It could have been ‘dung’. Only one book catalogued by the National Library has the S-word in its title, Dominique Laporte’s Histoire de la merde (Prologue) translated as a History of ‘shit’. The cover of the paperback is golden as if to overcome the repugnance of soiling one’s hand by picking up a book displaying the S-word. Laporte’s text opens with the establishment of the Academie Francaisie in the late 1630s to cleanse the French language, and concludes with the call from a French socialist, around 1850, for workers to pay their taxes with their bodily wastes for the general improvement of the French earth.
The S-word is avoided not just in speech but in practice in polite societies. As we proceed, we shall encounter instances of how the handling of shit has been an everyday activity for a majority of our forebears, whether in cooking food or in construction. At the other end of the social order, the Duke of Chandos, dedicatee of Handel’s Anthems, had not been afraid to get his hands dirty when he stole £600,000 from the English army to which he was paymaster. His Grace also instructed his hay wagoners never to return from London without a load of dung. Matters were more genteel in Georgette Heyer’s 1961 novel, A Civil Contract. Perhaps weary of being treated as a second- or third-rate Jane Austin, Heyer includes an exchange in which the heroine perplexes her beloved with a question about the Tullian drill:
‘Where did you read about it, Jenny?’
‘In one of your books. I have been looking into them, and trying to learn a little from them.’
‘My poor girl! Were you reduced so low? I had thought you brought a boxful of books down from London!’
‘O, I did! But Mansfield Park is the only one I’ve read yet. I kept it by me, and took it up whenever Artificial Manures, and the Four-Course System began to pall. And I must own, Adam, they do pall! …’
The couple proceed to discuss the relative merits as manures of Sticklebacks, gorse for turnips, burnt straw, lime, marl and rape-cake. Nothing so unseemly is to be heard in the Jane-ite parlours of Hampshire and at Bath.
Our distancing from unpleasant words is in keeping with the distancing that has taken place in lived experience. When my family moved to a new house 14 kms from the Brisbane GPO late in 1949, my father buried our night soil at the far end of the 48-perch block. How the family of eight next door managed on their 24-perches I dare not think. After a few months, the dunnyman appeared, taking away the pans and leaving sawdust. Ratepayers relied on torn-up newsprint before two-ply Sorbent. At the Australian National Univeristy in 1970, a student from one of the nearby towns submitted an essay with one footnote missing because, as he explained, he had been reading the article in his outhouse after someone had used the bottom half of the page that gave its date.
The low rates of return of the bowel-screening tests are evidence of the prevailing response to what the author of Deuteronomy called ‘that which cometh from thee.’ Twas not so with Childe who made a reputation digging through the ‘revolting quantity of refuse’ from past civilisations. To illustrate that we acquire our human nature through social evolution, he offers this instance of historical materialism: ‘The human infant has to learn from parents and seniors how to talk, how to dispose of his excrement, what to eat and how to prepare it, and so on.’ These rude facts serve as a lead into V. Gordon Childe the man, his career and the manner of his death. Given the significance he places on the agricultural revolution and then the urban revolution, to circle his life and writings is far from arbitrary in considering manure.
A recent TLS reviewer of an intellectual biography of M.I. Finley, Childe’s fellow Classicist and an erstwhile Marxist, set three criteria for how to judge a scholar:
- how many second-rate professors did you piss off?
- how many brilliant 16 year-olds did you inspire to follow your discipline? and
- how many of your books are being argued over decades after your demise?
Childe scores on all counts. For the rest of us, fame is to be a footnote in someone else’s Ph.D.
Vere Gordon Childe remains the finest scholar in the arts, humanities and social sciences ever produced in Australia. His fellow Marxist, Bernard Smith, refocussed how anthropologists and art historians viewed the Enlightenment, in European Vision in the South Pacific (1960). Childe’s greater distinction is that he systematised a discipline by crafting archeology with anthropology, Classics and history into Prehistory.
Pre-History is not prehistoric in any sense of ranking but derives from the need to rely on pre-written sources. As Childe asks in Man Makes Himself:
Why assume that, when the Arunta had created a material culture adapted to their environment, they at once stopped thinking together? They may have gone on thinking just as much as our own cultural ancestors, although their thoughts followed different lines and did not lead them to the same practical results, applied sciences, and arithmetic, but along what we regard as blind-alleys of superstition.
As a mere archeologist, Childe confessed himself unable to decide whether an ancient Egyptian got ‘more fun out of his back-gammon than a contemporary derives from two-up …’
Sixty years ago, come October 20, Childe ‘gave himself to death’, as the French put it. To conclude that he chose to end his life because he feared surgery for prostate would be as simplistic as to suppose that he did so because he was disillusioned with his scholarly quest or with his political ideals after Khrushchev’s denunciation of Stalin. As a confirmed bachelor, he had friends but no family to consider. His farewell letter concludes with serenity rather than despair:
I have enormously enjoyed revisiting the haunts of my boyhood, above all the Blue Mountains. I have answered to my own satisfaction questions that intrigued me then. Now I have seen the Australian spring; I have smelt the boronia, watched the snakes and lizards, listened to the ‘locusts’. There is nothing more I want to do here; nothing I feel I ought and could do. I hate the prospect of summer, but I hate still more the fogs and snows of a British winter. Life ends best when one is happy and strong.
The euthanasia legislation in Victoria falls a long way short of that Roman sentiment. Much as I endorse Childe’s right to choose when to end his life, I cannot approve of his putting the lives of others at risk to retrieve his body. Yet, such methods are imposed on us by those who deny us sure and affordable exits.
Childe became a thoroughly orthodox Marxist, which is to say that he conceptualised on the basis of relentless empirical research, disagreeing with no one more than with his earlier selves. Two short passages give us glimpses of how his mind worked:
Almost every statement in prehistory should be qualified by the phrase: ‘On the evidence available to-day the balance of probability favours the view that …’ Dates in years before 3000 B.C. are just guesses.
His writings are the quintessence of a speculative sensibility tempered by relentless research into those possibilities. His suggestive explanations have nothing of the Robinsonade, or about pre-formed individuals signing up to a social contract, or some such fairy story for how we re-make our social worlds.
A ready wit, he could be very naughty. His hand-made index for How Labour Governs (1923) is replete with cross entries such as ‘Australian Workers Union – a machine for making politicians’.
Offered Childe’s qualities of mind, this lecture in his honour will draw on his writings as often as possible.
In thanking you for the honour of giving the 2017 V. Gordon Childe Memorial Lecture, I should explain that my topic is your fault. Five years ago, in 2012, Gary asked me to address your Forum on ‘The Two Depressions’, meaning the 1930s and the crises that were still rolling out from the financial eruption of September 2008. No sooner had I accepted than I realised that there had been depressions before the 1930s. That strand in my thinking intersected with an understanding that capitalism is unique in as much as it must expand in order to exist. Moreover, capitalism needs a particular kind of expansion, not necessarily spatial or in the volume of products but of the value present in them. The commodities bearing those values have to be sold to secure a profit out of which some money-capital must be accumulated to fund the next bout of expanded reproduction. One result is a crisis-prone system, no longer subject to crises of sustenance, although famines have not disappeared for the poorest. Instead, crises of over-production arise from the need that capital-within-capitalism has to add value in excess of effective demand for its surges of commodities.
What part could manure play in this transformation? First, if there had been no continuing surplus of farm produce, then there could be no system of exchange; and if no regular exchanges then no pathways towards capitalism. Secondly, farm produce had to increase in order to supply larger populations, fewer of whom were engaged in their own sustenance because of urbanisation.
That tangle of problems provides the context of today’s presentation. How to link that mighty question with manure? I’ve piled up more than enough material than I can even touch on this afternoon. But if we don’t get down to it, our hour will be up and not a furrow will be turned. We shall set out from the four key words in the lecture’s title: Marx, Childe, manure and materialism, though not strictly in that order.
In this sesqui-centenary of Capital, one conventional wisdom surrounding that masterwork is that Marx wrote about an industrial revolution and hence had little to say about agriculture. Not so. Indeed, here is Marx: ‘In the strict sense the farmer is just as much an industrial capitalist as the manufacturer.’ How can that be? When Marx speaks of ‘industrial’, he is thinking in terms of what we can call the Four Cs:
- Co-operation, allowing for workshop divisions of labour;
- Centralisation of control over production and of money-capital;
- Concentration of productive resources, of which the fourth C,
- Conglomeration of labour, is pivotal because labour alone can add more value than goes into its reproduction.
Agriculture is there with enclosure as engrossment, that concentration of resources and centralisation of control. Moreover, the last third of volume III of Capital is devoted to theories of ground rent. (The links between manure and landed property rights – wrongs – will have to be the subject of a separate essay.)
The phrase ‘Industrial revolution’ is a way of avoiding class relationships, of ignoring what I call ‘the revolution inside capital’. For Marx, the ‘industrial revolution’ was not confined to dark satanic mills driven by steam engines, which, by 1830, employed only 250,000 horse-power throughout the United Kingdom, or about the same as all the infernal combustion engines polluting Katoomba.
That Marx’s account of capitalism is tied to agriculture and to ‘manure’ involves more than his absorption of Justus von Liebig’s Agricultural Science (Die Chemie in ihrer Anwendung auf Agricultur und Physiologie) shortly after its publication in 1840, which Engels had read before they met. Throughout their writing lives, they drew on Liebig to denounce the plunder of nature by capitalists while ridiculing a ruling class who ‘can do nothing better with the excrement produced by 4 million people than pollute the Thames with it, at monstrous expense.’ The sense of what Marx took from von Liebig is clear in this extract on capitalist agriculture, which, he writes,
… disturbs the metabolic interaction between man and the earth, … hence it hinders the operation of the eternal natural conditions for the lasting fertility of the soil. Moreover, all progress in capitalist agriculture is a progress in the art, not only of robbing the worker, but of robbing the soil; all progress in increasing the fertility of the soil for a given time is a progress towards ruining the long-lasting sources of that fertility.
Returning to this concern, Marx enriches his adaption of Liebig’s notion of ‘metabolism’ to deplore the imbalance that capitalism enforces between urban and rural populations, producing
conditions which provoke an irreparable rift in the interdependent process of social metabolism, a metabolism prescribed by the natural laws of life itself. The result of this is a squandering of the vitality of the soil, which is carried by trade far beyond the bounds of a single country. (Liebig)
Twenty years earlier, Liebig’s influence could be spotted in Marx’s 1847 book-length critique of Proudhon’s La Philosophie de la misère, while two of the ten immediate demands which Marx and Engels advanced in the 1848 Communist Manifesto were:
7. …. the bringing into cultivation of waste-lands, and the improvement of the soil generally in accordance with a common plan.
9. Combination of agriculture with manufacturing industries; gradual abolition of the distinction between town and country, by a more equable distribution of the population over the country.
In rebalancing the rural and the urban, Marx and Engels are thinking about both living conditions for labourers and the transfer of urban wastes to replenish the soil. In Marx’s critique of the 1875 draft programme of the German Workers Party, he repeats that ‘[l]abour is not the source of all wealth. Nature is just as much the source of use values … as labour, which itself is only the manifestation of a force of nature, human labour power.’ The contrary view, he chided, is ‘to be found in all children’s primers’. This afternoon we enter the realms of scholarship through the portals of historical materialism.
Gustav Flaubert, in compiling his collection of bourgeois stupidities into ‘A Dictionary of Received Ideas’, offers this entry for MATERIALISM:
‘Utter this word with horror, stressing each syllable.’ MA-TER-I-AL-ISM
‘Materialism’ carries at least two meanings, one ethical, the other philosophical, with two opposed senses in the latter: the eighteenth-century French ‘mechanistic’ kind and a dialectical form. No necessary connection operates between materialism as avarice and the conviction that there are no spooks. Here, Marx is exemplary as someone who spurns worldly goods, is fired with a fierce morality against injustice, and rejects the presence of other-worldly powers. Equally, to be idealistic has no taproot in Plato’s Forms or the Hegelian Idea. Historical materialists allow plenty of space for ideas, as we shall see in connecting manure to magic and, in a different way, with the emergence of agricultural science.
Were I to boil historical materialism down to a single sentence, it would go like this: We become what we do, as a species and as individuals. One way to elaborate on that summary is by reconstructing the title to Gordon Childe’s Man Makes Himself, first published in 1936. No challenge will be offered to its substantive intent of its title. Instead, each of its three words will be replaced the better to bring out Childe’s lines of intent. In short, we shall replace ‘Man’ with ‘Humans’; extend ‘makes’ into ‘made and re-makes’; amend and expand ‘himself’ to ‘Themselves’ but then slip across to ‘Ourselves’. The result is Humans made and re-make ourselves. In saboutaging the snappiness of Childe’s title, I am not putting words into his mind. Rather, my unmarketable version is an almost exact summation of the case he presents across his life’s work.
‘Man’ as species
I say ‘almost exact’ because, for a start, ‘Humans’ is inadequate. Childe’s book opens with the processes of hominisation, that is, how our progenitors remade themselves into homo sapiens. He begins by inviting us to time-travel back 500,000 years until ‘human history joins on to natural history. Through pre-history, history is seen growing out of the ‘natural sciences’ of biology, palaeontology and geology.’ An accurate rephrasing of the title would have to begin some two million years ago to allow for the branching from which pre-humans ‘made’ and ‘re-made’ the animals we call humans.
‘Man’ as gendered
The other reason for replacing ‘Man’ with ‘Humans’ is to avoid gender bias. On this matter, Childe’s text is replete with surprises, such as in this sentence: ‘The casting of bronze is too difficult a process to be carried out by anyone in the intervals of growing or catching his food or minding her babies.’ Even today, it comes a bit of shock to associate women with metal work. The import of this passing reference is as nothing in comparison with what Childe contends when he takes four pages to investigate the origins, development and consequences of pottery-making:
The constructive character of the potter’s craft reacted on human thought. Building up a pot was a supreme instance of creation by man. The lump of clay was perfectly plastic; man could mould it as he would. In making a tool of stone or bone he was always limited by the shape and size of the original material: he could only take bits away from it. No such limitations restrict the activity of the potter. She can form her lump as she wishes; she can go on adding to it without any doubts as to the solidity of the joins. In thinking of ‘creation’, the free activity of the potter in ‘making form where there was no form’ constantly recurs to man’s mind; the similes in the Bible taken from the potter’s craft illustrate the point.
Hence, it is women who lead the way towards the appreciation of a great truth in materialist dialectics: the natural world is malleable. That understanding came from activity, just as all knowledges, like language, were social products and collective possessions. Throughout Man Makes Himself, Childe is expanding on leads which Engels presented in his essay, ‘On the Part Played by Labour in the Transition from Ape to Man’.
Every point in favour of changing ‘Man’ to ‘Humans’ adds to the need to replace ‘makes’ with ‘remakes’. Childe links the plasticity of pottery to the re-making of our mental capacities, then to magic in craft, and onto the experimentally-based sciences.
Despite the fad for the plastic brain, A.B.C. presenters persist in the oxymoron of alleging that we are ‘hard-wired for plasticity’. The ‘in-our-genes’ variant of fixedness and determinism is shadowed by the racism of bloodlines. An indigenous man on ABC around 21 August declared that he had ‘40-80,000 years of culture in my DNA.’ It is disputable whether any of us has any culture in our genes. What we do all carry are more than three billion years of evolution through natural selection. We share some DNA with the Second Chimpanzee and also with bananas – indeed, with every living form, plants, as well as animals.
How then are cultures transmitted? We inherit social traits from our families and can pass them on, but not physiologically. Nonetheless, there is some overlap. Being able to manipulate their digits and tongues allowed our distant ancestors to develop tools and language: ‘In the same way we do not have to discover for ourselves how to operate a screwdriver, or a brace. Most of us are taught by our parents, schoolfellows, or the dealer who sold us our car.’ Childe explores such processes throughout his 1951 book, Social Evolution. Marx gives an instance from a different domain by noting that, by the middle of the nineteenth-century, a schoolboy could learn the binominal theorem in an hour, an intellectual achievement which had taken humankind centuries to master. Evidence for the social evolution of that mental capacity is in school primers. We can even know a little about the motivation for the originating mathematicians from the social needs that their equations went towards meeting. By contrast, how much can ever be known about the origins of practices such as manuring which left few if any traces?
In the absence of written evidence, as Childe reiterated, prehistorians must rely on their skills at interpreting artifacts but they can also read the marks written into the earth, such as patterns of ploughing. It is harder to trace the addition of mineral fertilisers and harder again for any application of organic ones from two or more millennia ago. The mineral additive which left the most obvious tracks was the iron on a plough.
Who invented manuring? The answer is simple. The same people who invented farming, funerals, weaving, pottery and song. In short, everyone and no one. The archaeological record gives us some idea of when and where those practices appeared, when they became widespread and how they changed, but less than nothing on why our ancestors stumbled onto them. Some alertness to the worth of fertilising might have been arrived at by extrapolating from natural processes, such as the silt from floods. Or the earliest cultivators might have come to realise that their fire clearing produced ash which had enriched the soil. Childe hazards a further guess about the recognition of benefits from animal wastes: ‘It might be noticed that crops flourished best on plots that had been grazed over. Ultimately, the value of dung as a fertiliser would be realised.’ ‘Ultimately’ explains nothing. Moreover, how long would that recognition have taken where deposits of dung killed off plants around their edges? To speculate about when and where manuring began, is to ask the same about the move from hunting to the domestication of large animals so as to have access to piles of dung. Did cultivating the soil come before getting the ‘dung’ to work its magic? Sedentary occupation is evidence of having discovered some way of replenishing the soil and thus not having to keep moving camp. The application of dung or other fertilisers is a likely inference from prolonged settlement, yet that conclusion is still miles away from an exact answer to when one or other fertiliser was first applied, and where? Rather than a diffusion of the worth of manuring from a single group of cultivators, it is more than likely that the practice had to be discovered over and again, even in the same areas over time.
Given reports of dung’s being used as a fuel and a building material, how much was left for manuring? Childe was put to wondering too:
On the other hand, societies do seem to have discovered after several thousand years that flint-armed darts accurately aimed with a spear-thrower secured more meat than the most realistic picture of a bison laboriously draw in a dark cave. It apparently took longer to recognise that the dung of oxen spread upon the fields ensured better crops than the blood of oxen sacrificed on altars.
Fertilising would not become widespread for as long as its benefits could be attributed to the Goddess Fortuna, whose name implies the bringer of fertility. Cultivators could cling to ill practices for as long as populations remained small and fresh soils could be farmed to the point of depletion.
A cornerstone of historical materialism is how human labour remakes our physical environments as we adapt to survive. Those processes lead to the question: are soils natural? How much is rubble and rubbish? The building of settlements on the detritus of earlier ones is a stable of archeology, notoriously so in the futile search for Homer’s Troy.
From where did the soils come? Were they yet another free gift of nature, like sunlight, or are they one more consequence of sensuous human activities as our kind remade itself? Australia Felix is the outcome of millennia of fire-culture removing the forests, thereby enriching the soil with carbon. Anthrosols result from both farming and extractive industries, such as quarrying and mining, as well as terracing and irrigation (water meadows), but are also the outcome of land reclamation from the seas, or the drainage of bogs, fens and swamps. One ill-consequence has been soil erosion leading to dust bowls, which raised doubts in Childe regarding mechanised farms.
Agricultural Revolutions had their origins in the fertile crescent of the Nile and the Euphrates but, as Childe emphasises, enormous amounts of human labour had to go into taking advantage of that flood:
the swamps had to be drained by channels, the violence of the flood-waters to be restrained by banks, the thickets to be cleared away, the wild beast lurking in them to be exterminated. No small group could hope to make headway against such obstacles. It needed a strong force capable of acting together to cope with recurrent crises that threatened drainage channels and banks. The few original patches of habitable and cultivatable land had to be extended with sweat and blood.
Soils owe something to our labours, albeit not as much as our survival owes to the earth. The management of the workings that transformed both called for social structures based on landed property, with their class relations upheld by magic and religion.
Less natural selection
The first agricultural revolution ‘gave man control over his own food supply’, even though those farmers were by no means sedentary, but had to keep moving to virgin soils. The second agricultural revolution in England – more accurately called the opening phase of the industrial revolution – revived that spatial element through the reclamation of wastes and, from 1750, a burst of the enclosure of most commons. At the same time, the old imbalances of arable and pasture were reduced by concentrating each kind of production in areas for which they were better suited, with grains in ‘the free-draining, light soils’ while ‘some of the clays went down to grass.’ These rearrangements in part answered the Medieval question: how many sheep are needed to raise an acre of corn?  Meanwhile, the transformation in Scotland involved introducing a different breed of sheep, the Cheviot, to the Highlands.
The rupturing of ties between blood and soil got underway with grain shipments from Sicily to Rome, declined with the Muslim closure of the Mediterranean to revive after 900, before taking off in the 1500s with exports from the Baltic to Western Europe. Meanwhile diets were being transformed by the arrival of corn, potatoes and tapioca from the Americas.
Niles Eldridge spells out the global dimension of our re-making of the earth in his book Dominion:
Taking control over production of our own food supply, we became the first species in the 3.5-billion year history of life to live outside the confines of the local ecosystem.
… in stepping away from local ecosystems and in substituting cultural devices for physiological and anatomical adaptations, we have unwittingly changed the rules of the evolutionary game.
The environments to which all species must now adapt continue to be transformed by social practices. The significance that Darwin allotted to isolation for speciation on the Galapagos has been diminished. Where is such isolation to be found today? Perhaps only in some of the warm waters under the Antarctic ice sheet, though scientists are boring into those hideouts.
To conclude this segment on historical materialism as sensuous human activity, we return to the book’s title. As with ‘Man’ and ‘Makes’, ‘Himself’ presents a double problem. One objection can be overcome by replacing the gendered pronoun ‘Himself’ with ‘Themselves’. That substitution is inadequate. From the gender-neutral third-person plural ‘Themselves’ we must move to the first-person plural ‘Ourselves’. The pronoun must be plural because our remaking is nothing if not social, though not necessarily sociable, as is shown by class and gender oppressions. ‘Our’ is less than satisfactory since it is confined to a re-making during no more than the last 120,000 years. ‘Them’ suffers from the opposite inadequacy. We want a pronoun to convey ‘them’ becoming ‘our’.
Having taken up so much time defining ‘materialism’ though refining one of Childe’s book titles, I now need to refine ‘materialism’ from the angle of how historical materialists deal with the power of ideas. We can do so by heading into Childe’s thoughts about magic in agriculture, before considering the degree to which those practices differed from those developed for the emergence of agricultural science after the 1760s.
Just as Childe was not afraid to deal with the crudity of manure, so he delved into magic. In delivering the 1949 Sir James Fraser lecture, he displays how subtle and refined an historical materialist can –and should – be. The lecture’s title was Magic, Craftsmanship and Science, rather than Fraser’s triad of magic, religion and science. Craft has dislodged religion, with ‘doing’ taking the place of prayer: ‘The acts were the ideas, not expressions of them.’ Yet crafts call for more than action. They call forth magic: ‘Every operation of every craft must be accompanied by the proper spells and the prescribed ritual acts.’ How could it have been otherwise? How amazing must it have been to have taken part in – or even to observe – the transformation of copper ore into bronze, a procedure not unlike an act of creation: ‘The Bronze Age gods were conceived in the form of man, the ruler of other men, and also man, the artificer, moulding and creating form in the shapeless matter like the potter.’ Small wonder societies invested metals with mystical properties which required taboos and rituals. Eventually, the actuality of such transmutations encouraged alchemists. Such occult practices aimed at forcing nature to reveal its secrets whereas miracles arrive from outside the natural order, requiring its suspension. Magic combines material elements with incantations and ritual to wrest power from nature to serve human ends, unlike just praying for rain.
In dealing with the power of magic over our imaginings, Childe recognised that ‘[t]he question is not whether magic was a substitute for the craftsman’s technique but rather was it supplementary or only complementary to applied science.’ Taking magic to be supplementary, Childe would be the last to dismiss magic as irrational and illogical: ‘… it is above all in societies where skill in craftsmanship is highly developed that importance is attached to magic precautions and ceremonies.’ He spots a dynamic which flows from even the rudimentary capacity to make natural resources serve human need: ‘Again, technological progress depends … also on a multiplication of wants.’ In the absence of any more efficacious offering, the want to go on living was met by a talisman from craftsmen whose spells put magical powers into it during its manufacture.
The inexplicable that connects the commonplace to magic is even stronger for our relations with plants because they come to life independently of us, yet our existence depends on their doing so. The seemingly spontaneous generation of life out of apparently dead matter fascinated the finest scientific minds until microscopes put an end to their speculations, yet will never silence the poets: ‘April is the cruellest month,’ Eliot wrote, ‘breeding/ Lilacs out of the dead land …’.
Underpinning the crafts of pottery and metallurgy are those of food production. In The Golden Bough, Fraser contends ‘[t]hat, in instituting rites designed to assist the revival of plant life in spring,’ humans knew they would not survive were plants to perish. Hence, they believed that their ceremonies could ‘influence the course of nature directly through a physical sympathy or resemblance between the rite and the effect which it is the intention of the rite to produce.’ A Marxist contemporary of Childe’s, the Professor of Classics at Birmingham, George Thompson, observes that ‘by comparison with cattle-raising, the work of tilling, sowing and reaping is slow, arduous and uncertain. It requires patience, foresight, faith. Accordingly, it is characterised by the extensive development of magic.’ Childe gives the example of the Bundi in the New Guinea Highlands who wrapped up ‘pebbles in bark and bury them in their gardens to ensure the fertility of the crops;’ Swiss excavators uncovered ‘rounded pebbles carefully wrapped in birch bark’ from thousands of years back.
In this vein, Childe sees more in cave painting than an aesthetic impulse since our forebears had no concept of Art with a capital-A, that is, of marketable items infused with the aura of individual genius:
All these considerations show that cave art had a magic purpose. An artistic production is, after all, an act of creation. The artist scratches upon the blank wall, and lo, there is a bison where formerly there had been none! To the logic of the pre-scientific minds such a creation must have a counterpart in the outside world that could be tasted as well as seen. As surely as the artist drew a bison in the dark cavern, so surely would there be a living bison in the steppes outside for his fellows to kill and eat. To make sure of success, the artists occasionally (but rarely) drew his bison transfixed by a dart, as he desired to see it.
To Childe’s way of reasoning, the Arunta saw themselves as food producers by their dances and ceremonies, not just as seed gatherers:
‘Our magic rites,’ an Arunta would say, ‘are just as necessary and efficacious in keeping up the supply of emus and grubs, as the digging and weeding done by wretched cultivators.’
Many of them were indeed the ‘People of Plenty’ with lots of spare time for what their un-settlers named ‘Dreaming’, but whose stories are creation myths and totems with significance for food gathering, hunting and fishing, and as often about water as about ‘land’, though those resources are inseparable for survival.
For the first Agricultural Revolution to triumph in the fertile crescent required more than a benign hand of nature to send nutrient-rich floods each year. Among the generations who depended on the Nile for their bread, the cycle of flood and fertility underpinned belief in rebirth, and of an after-life. Hoeing, property performed, was deemed an act of piety towards the Earth-god: ‘Indeed, canal-building was believed to be a major occupation of those in the blessed world beyond death.’ ‘Canal-digger’ became an important title for rulers who laid claim to the beneficial consequences of the work carried out by labourers who ‘dredged channels, dug ditches, built earthen dams, constructed dikes and basins, and raised water with buckets.’ Their activities too were considered to be part of a holy occupation. With the passage of time, astrology overlapped with astronomy from the predicting the inundations.
In no sense need we take spells and rituals seriously in the same ways as did their practitioners. However, materialists must take magic as seriously, as Childe and Thompson did, as one more sensuous human practice. Ask not just why everyone once believed in such spells but also why so many still need to believe. Marx called religion an opiate, not because it put people to sleep, but because it reduced physical pain and mental anguish so that we might retain the strength to go on.
Acceptance of that precept does not resolve the puzzle posed by Marx: how is it that the one mode of production spawns so many distinctive superstitions and institutional religions? Once we know both the mode of production and the beliefs, it is all too easy to work back from creed and ritual to need and reproduction. The demanding task is to trace the development of ‘the forms in which these needs have been apotheosised… from the actual, given relations of life’; only that pursuit, he writes, is historical, materialist, and thereby can be deemed scientific.
When experiments by practitioners of the occult sciences failed, the priests or magi failed most often to learn from those reverses. There are no grounds for concluding that the practical farmer did much better. Some killed worms to stop their eating seeds;  French farmers who saw the higher yields from farms with natural deposits of lime did not at once add any of it to fields that did not. And it must be added that not all experimental scientists during the nineteenth-century were safe from priest craft to conceal their errors and willful ignorance, or from indulging in self-promotion within the interests of the class to which they had attached themselves. Rudolf Virchow opposed Pasteur’s germ theory for infection as a challenge to his own primacy of the cell and denounced Darwinism as a source of socialism.
We shall make little sense of developments in agricultural science before the 1900s without attending to the even more dramatic changes in how the physical and chemical worlds were understood. From the 1640s, the intellectual context for experimentation had been transformed by Descartes, Galileo, Liebniz and Newton, supported by Royal Societies and learned journals. No longer was Aristotle the fifth apostle. Particular discoveries enriched an understanding of the nature and hence the needs of plants and soil types, although the conceptual and the empirical did not always nourish each other.
The presence of calcium phosphate in bones was recognised in 1769, to be extracted from bone ash two years later; nitrogen identified in 1772, ammonia gas in 1774, oxygen in the 1770s and potassium in 1808. Jan Ingenhousz identified respiratory cycles in plants in 1779, showing that oxygen is absorbed at night when carbon dioxide is exhaled, with the reverse cycle by day; at the same time, he saw the importance of sunlight if leaves were to produce oxygen. Linnaeus’s writings on the sex lives of plants had been translated by the mid-1780s. Little progress in understanding the exchanges between soils, plants and the atmosphere could be made for as long as water was considered a single element and not a molecule. Moving between botany and zoology, Lamarck coined ‘biology’, identified invertebrates and proposed evolution under the label of transformism around 1800, becoming Professor of Worms at the Jardin de Plants. Cellular physiology emerged thirty years later with works by M.J. Schleiden for plants and Theodor Schwann for animals; most of their accounts were ‘quite wrong’ since ’the data were incorrect and the inferences, while logical, were false.’ Then came Virchow’s lectures on cellular pathology in 1858. Evolution within species rather than between them had been widely accepted before Wallace and Darwin presented the novelty of a mechanism for the latter through natural selection. By 1880, Pasteur’s work on microbes challenged von Liebig’s bias towards minerals as the prime, if not the sole contributor to improving fertility.
With so many fundamental discoveries falling upon each other, it should be no surprise that so many eminent scientists nailed their reputations to at least one huge mistake: Darwin’s was ‘blending’, while Virchow denied the significance of microbes in disease.
In 1917, two British researchers summed what was known and how much remained uncertain after some seventy years of field trials at Rothamsted Experimental Station. Their modest efforts were overshadowed by Fritz Haber’s concentration of the forces of production, courtesy of the German warfare state; under his leadership, scientists at the Kaiser Wilhelm Institut, by 1913, had devised a catalyst for the commercial production of ammonia for fertilisers and explosives, without which the war might well have been over before Christmas. Although celebrating ‘A Century of Progress in Agricultural Chemistry’, one of the speakers at the 1940 symposium on Liebig’s book, had to admit that ‘[t]he science of plant physiology is so youthful that the recording of new observations of fact still remains generally more attractive than attempts to coordinate and interpret them …’.
We began with the Old Testament and shall close with a much shorter text which served Childe as an old testament. I speak of ‘On the part played by Labour in the Transition from Ape to Man’ by Frederick Engels. As we saw, in Man Makes Himself, Childe gave flesh to its bones. In his Progress and Archeology from 1941, he recognised the zig and zag among the consequences of the emergence of homo sapiens yet found no grounds for despair, not even in the rise of Nazism. I hesitate to project Childe’s faith in a degree of progress into the present. Sixty years after his death, he might conclude that it had been a mistake to have to come down from the trees.
Instead of even hinting at what we cannot know about a dead man, I shall quote the caution delivered by Engels. Those pages are at once a marvel of prose and a profane sermon on how our species might yet learn to survive:
Let us not flatter ourselves over much on account of our human victories over nature. For each victory nature takes its revenge on us. Each victory, it is true, in the first place brings about the results we expected, but in the second and third places it has quite different, unforeseen effects which only too often cancel the first.
The people, who, in Mesopotamia, Greece, Asia Minor and elsewhere, destroyed the forests to obtain cultivatable land, never dreamed that, by removing along with the forests the collecting centres and reservoirs of moisture, they were laying the basis for the present forlorn state of those countries.
Thus at every step we are reminded that we by no means rule over nature like a conqueror over a foreign people, like someone standing outside nature – but that we, with flesh, blood and brain, belong to nature, and exist in its midst, and that all our mastery of it consists in the fact that we have the advantage over all other creatures of being able to learn its laws and apply them correctly.

 The choice of terms for social relationships is never going to be neutral.

 That combination was far from straightforward as Rene Dumont learned when investigating poverty in the Cameroons. In a village with low soil fertility but with a vast pile of cattle manure, the chief explained his refusal to allow its use as fertiliser: ‘I am old and shall soon die. Then when passers-by see this great dunghill, they will think of me and will say to themselves, “He was a great chief, for he must have had a great herd of cattle to leave such a pile of manure.” ‘, Types of Rural Economy, Studies in World Agriculture, Methuen, London, 1957, p. 85.
