The Natural/Artificial Distinction


Ophelia, Sir John Everett Millais
There's a lack of clarity surrounding the words natural and artificial in common, everyday speech. Perhaps natural carries this sense of everything that's not us, not human beings or human-made whereas artificial might refer more typically to things that are mechanical. Sometimes we'll describe the artificial as synthetic which just passes off the confusion since we're not clear what that means either.

A common argument against even considering this subject is that the natural/artificial distinction is meaningless for the simple reason that everything is natural. Nature is everything, humans are nature, ergo whatever we are or do must therefore be natural...by definition. Cars are natural, cities are natural, differential equations are natural, petroleum processing is natural, if we bring ourselves to extinction in a nuclear holocaust or environmental collapse well, that'll be natural too...by definition. However, let's suspend just for a moment taking all the complexity of human existence and submerging it in the molecular acid of cold reason until meaning is reduced to one thing or perhaps nothing at all. Instead, we'll imagine for a moment that this distinction might exist and see what these terms could mean and where the boundary between nature and artifice might lie.

Watch your Language

A first step might be looking a bit closer and giving some definitions to the words under discussion. I appreciate etymology for that. Often the origin of words reveals their intended meaning even if that meaning tends to shift over time and place. Nature for instance originally referred to something born. We have the echo of this meaning in the words "nativity" and "natal" care. The Taoist of ancient China held a concept closely allied with this sense of nature called "wu-wei" (無爲), the "not doing" or "not making" yet implying growth as an internally generative cultivation. So perhaps we could come to a provisional agreement that "natural" indicates some thing or action unforced, not deliberate, that presents itself spontaneously, of its own accord.

So what about artificial? Artifice quite literally conjoins "art", which includes what we'd call today "craft", together with "making". As arts and crafts are already things that are made, this word really reinforces the notion that what is artificial is deliberate, intentional and purposeful, in some respects the polar opposite of how we previously defined natural. Yet as originally expressed, the artificial was also something quite human. Which brings us to the thorny question: What does it mean for a human being to behave naturally?

Well, no simple answers will be forthcoming; however, perhaps we'd benefit from looking at language itself as an human phenomenon. Language has been explained as a collection of symbols and signs that occasionally represent but more often serve as a token of or point towards some thing or action. A repeated and fascinating observation is that children instinctively sense which of the sounds around them have symbolic meaning and seem to learn the languages they're exposed to effortlessly. Furthermore, many children have been observed to spontaneously generate their own independent verbal and gesticular vocabulary shared in a subset of siblings and friends. I've vague memories of doing so myself and definitely observed this on a fairly sophisticated scale with my nephews when they were little just a few years ago. Language at some level does seem to be, dare we say, natural human behaviour.

Yet at another level language is confessedly unnatural. We subject our already verbal and often  literate youth to at least 12 years and up to as much as 20+ years of what linguists call codification: reading, writing, spelling, grammar, syntax, style and usage are just appetisers for specialised language of a given field. Essentially, years are invested in curbing the will of children to conform to a standardised system of convention. Then when every trace of spontaneity has been forcibly ground out of them, we make silly declarations such as "thought is impossible without language" and "literacy is the key to freedom". Well, that last one is particularly rich after two decades of stern obligation and six figures of inescapable student debt.

Language quite literally is based on ignorance; in adopting a language one ignores the vast cacophony of sound, rather privileging a select few of them for attention and meaning. It is widely acknowledged that there are two paths to knowledge. First it can be directly experienced, bodily and through the senses. However, knowledge can also be conceptualised and this is where language plays a major role. Therein also lies the danger, as we can expand our ignorance to the rich, often inexplicable embodied experience of life itself, instead privileging language with all its constraints as the primal reality we choose to acknowledge. Today we have constructed a highly sophisticated, intellectual, systematised, global society that essentially lives within its own codified projection of reality. My advice is: watch your language, living inside your head is dangerous.

Imitation and Imagination

Traditionally in the world of art, the tension between the natural and artificial was always present and self-aware. In a certain sense "art" is embedded into the word artificial; all art is artifice. Yet nature was revered as an object of study and likewise a subject of the most profound contemplation. How artists and craftsmen confronted artifice in their depiction of nature as you might suspect is a deep personal interest of mine. For the aspiring young apprentice becoming an artist involves a lot of copying, teaching the hand to render what the eye sees, be that the work of master artists or the ultimate wellspring of inspiration: nature herself. This continual act of copying we call imitation, the aspect of artifice that cleaves closest to nature.

Nevertheless, imitating nature is not that easy. Something as simple as a leaf contains a world of complexity. The more you look, the more you see. Also, the medium in which we're representing the the things we see provides further difficulty. Pencil and paper, paint and canvas can only represent in two dimensions what exists in three. Sculptural mediums such as stone, wood or clay are relatively clumsy materials that are incapable of conveying the delicacy, detail and nuance that exist in nature. All of these mediums can only capture a frame, a snapshot of what is most often a dynamic, living reality embedded in a particular time and place, full of smells, texture and temperature. This is where the simple, practical aspect of Imagination enters. The artist must first absorb the infinite complexity of the object under consideration in its context. Then in an analogy to language, the artist ignores all but a handful of qualities to privilege what he considers to be the essence of the thing, his representation is an act of human communication.


The lotus flower is one of the most prominently depicted motifs in both Eastern and Western art. The flower of the water lily has the unique characteristic of opening in the morning and closing in the evening. For the Egyptians the lotus was the ideal symbol of the cycle of birth, death and rebirth. It featured prominently on personal effects, furniture and great monuments of architecture. Although highly convetionalised, often in a regularised frieze pattern alternating blossom and bud, the lotus motif is unmistakably recognised as representative of the flower. The flower and other myriad features of the plant are not depicted verbatim. Rather, that which was felt best captured the essence of the flower was retained and given prominence, a deliberate series of decisions that we can appreciate even thousands of years later.


In Classical art there is no more recognisable ornament than the acanthus leaf. Furthermore, it is depicted in a dazzling variety of ways, most of which do not occur in nature. The structure of the leaf of the actual acanthus plant is unbelievably complex. There is no end to the detail. That it became the preferred inspiration for rendering in stone is therefore somewhat perplexing. Like the lotus the acanthus became a symbol of resurrection and rebirth. A hardy weed, it is in fact quite difficult to eradicate. Even when you think you've uprooted it completely, there it is again springing back to life the next season. Acanthus features prominently on the Roman Ara Pacis monument, both in the more literal leaf interpretation as well as the flowering stalk and conventionalised scrolling acanthus or rinceaux design. This is of course complete artifice as regards acanthus, adapted from other spiraling vines that are common in the Mediterranean. An artist both highly skilled in imitation of natural forms as well as having developed his imagination to adapt them to a highly stylised design thus created a composition that at once feels natural yet artistic, one could say perfectly human.


The great masters of the Renaissance are often regarded as humanists; nevertheless, they were certainly naturalists as well. It might well be said that their particular interest in humanity was a subset of their great interest in all of nature. Leonardo da Vinci is of course renown for his enigmatic capture of the human condition as displayed in his paintings such as The Mona Lisa or his fresco The Last Supper. However, what is less known about him was the intensity of  preparation invested in nature studies for his compositions. There are literally hundreds of his extant sketches of plants, leaves and flowers that have survived.

In one of Leonardo's most iconic paintings, The Virgin of the Rocks, the scene
depicts a great human drama with divine pretensions. The positioning and lighting of the subjects, the delicacy of the facial features, and the detail of the folding of veil and cloth indeed worthily capture our immediate attention. However, in a nod to nature, the more you look the more you see and we begin to appreciate how much work, experience and inherent skill is found in a painting like this. The foliage certainly was not a bit of filler, a mere afterthought. To the contrary we find the plants and flowers rendered both accurately and artistically. As such they would be immediately recognised by a botanist today. Here we see Imagination operating in its other, higher capacity. Unlike the reduction and conventionalisation typifying ornamentation, in this narrative scene Leonardo paints a picture ostensibly of what was yet in another sense a lofty depiction of what could be. It's an aspirational image that takes the very best of what is and pushes it to the foreground. In essence, we witness here a preeminent example of the distinctly human contribution to the natural.

Entropy and Generation

"The entropy of the universe tends to a maximum" - The second law of thermodynamics, Rudolf Clausius

During the Industrial Revolution scientists and engineers quickly turned their attention to difficulties with the machines that they were constructing. First, in the conversion of fuel into mechanical energy and again in the simple operations of the machine much of that energy was converted and subsequently dissipated in the form of heat. Secondly, the machines themselves would break down over time. In the mid-19th century Rudolf Clausius coined the term "entropy", meaning an "inner transformation", to describe this tendency for things to devolve from highly ordered and complex states into cycles of decay and eventual chaos. As the Enlightenment vision of nature at the time was materialist, this discovered "law" of thermodynamics was projected onto the entire universe. In an unwieldy union with the pre-exisiting Judaeo-Christian conception of God as the great potter and man having been made in his image, there was a correlation made between divine artifice (nature) and man's: it was all going to break down eventually.

To a large extent I believe humanity is still saddled with this world view. For example, the best concept that we seem to have come up with thus far to protect the natural environment is "sustainability". It's not a very good one. The main focus seems to be on improved mechanical systems that are more efficient, produce less waste and utilise cleaner sources of energy. These are directed in turn by self-enclosed control systems be they digital automation primarily associated with industrial production but now increasingly integrated into the state and corporate bureaucracies that constrain and encode behaviour through policies, standards, laws and codification.A vision of life and nature as a machine with systems and code to look after her. In this way of thinking, an improved care of nature comes from advancement in our mechanical models and efficiencies of control systems.

So what's the alternative? A bit of humility; look to nature and learn. Everything we've come to understand about nature indicates that it is the very opposite of entropic. Our universe has cyclically grown and expanded from a raw state of chaos to higher states of successively ordered complexity. Yet we don't have to look far into the infinitude of space to understand this, it's an ongoing process right here on planet earth. Life on earth is generative, so much so that we can see in human timescales the patterns unfolding before us. Land areas devastated by natural disaster or human exploitation heal rapidly if left alone; restated in technical language we could say that life is negentropic, manifesting a tendency to move from disorderly states of chaos to enriched, complex environments. Here is the hopeful part, human beings too are fully capable of being generative. We can and have nurtured for millennia animals and plants bringing land into higher capacities for both cultivation and richer environments for life to thrive. A seeming paradox from a mechanistic perspective, the key to being generative appears to be doing less, at least consciously. Like "nature", "to generate" has the same original meaning "to beget" or "give birth". This can be illustrated with a very personal example. The development from an embryo to a fetus to a delivered child is an extraordinarily complex living process which we still don't fully comprehend. Yet at another level we totally understand, we do it successfully all of the time! We know it so well in fact that we hardly have to think about it.

So once again, what does it mean then for a human to be generative, to act naturally?
I'll leave you to contemplate an ancient Taoist analogy:
"When in doubt look at water, it always knows what to do." Stop trying to flow upstream.

Natural Building & Traditional Craft


Initially published on Traditional Building Magazine online February, 4th 2019

Last autumn I was passing through the Shenandoah Valley of Virginia and decided to drop in on a good friend of mine, traditional timber framer Jordan Finch. Jordan and I had taught together at the American College of the Building Arts in Charleston, SC. When I arrived he was busy hand chiseling and fitting the mortise and tenon timber joints for a project with fellow timber framer Robert Laporte. Robert and his wife Paula have a company EcoNest that specialises in design build of homes, traditionally timber framed with light clay straw infill, that are typically lime plastered inside and out. I gave them a hand for a day and ultimately Robert recommended me to the homeowners for the plasterwork. The whole process was fascinating and I'll endeavour to share from this experience the type of home that is today possible by the combination of highly skilled means and methods of traditional craft with the truly sustainable ethic of a contemporary natural building approach.

Timber Framing and Light Clay Straw

Robert Laporte has a young apprentice
You can't get more sustainable than responsibly cultivated and harvested timber. A properly constructed and maintained timber frame structure can endure for centuries. Timber framers are really architects in the original sense of the term, master (arkhi-) craftsman (tekton), who design and undertake the construction of the primary structure that holds the building up. The next generation of Finches were in on the action as well. Apprenticeship can't start too early on the long road to mastery!

Light Clay Straw Infill
A benefit of timber framing is that almost all of the construction of the members can be carried out in shop conditions and brought to the job site for a rapid assembly. Lincoln logs for grown ups! The next phase of the project was to shutter and infill the timber framing with light clay straw. Light clay straw is a contemporary adaptation of some very ancient traditional wall assemblies: cob and rammed earth. Similar to cob the mix is a combination of loam (sand and clay) and perhaps a bit more straw or other woody fibres. That cob-like mix is then stuffed and lightly tamped between form not unlike rammed earth but not quite as dense. The thermal mass of the loam and the thermal insulation of the straw make for a very interesting "dynamic insulation" that can contribute significantly to a very comfortable indoor environment in a variety of climate conditions with a minimum of energy consumption. A similar approach was used for most of the earthen floors which utilised a mix richer of clay, finer fibres and finished with linseed oil. Next up: loads of plastering with another good friend, Rob Wozniak and his team from Preservation Works!

Interior Lime Rendering and Clay Finish

For the interior perimeter walls we installed lath followed by removable wooden grounds that we used for scratched render followed by applying and leveling the brown coat with rods and compressing with wooden floats the following day. The plaster mix was a combination of two local sands, hemp fibres for tensile strength and Lafarge Natural Hydraulic Lime as the binder. The first week all of the preparation and scratch render went up and with the hydraulic properties of the lime setting in we were in good shape for the next float coat and clean up by week two. Lime plasters were the perfect choice as they are exceedingly durable and share the moisture permeability of the light clay straw substrate.

Whereas all of the interior perimeter walls received lime plaster, the inner walls had been framed and received drywall. For the finish we applied American Clay plaster as a nominal 1/8" veneer over both surfaces, the lime plaster and the drywall, for a unified finish. Lime and clay are both traditional materials, practically inexhaustible resources that are completely non-toxic. The means and methods of application go back to the dawn of civilisation: hawk, trowel, rods and floats. The work is physical but not brutal on the body. Essentially plastering makes for good exercise!

Exterior Lime Stucco

The exterior lime mix and application was basically the same as for the interior; sand, hemp fibre and hyraulic lime applied in a scratch and brown coat. However, instead of finishing with clay, the final coats were of lime stucco as well pigmented with mineral tints. The traditional design principle of "having a proper hat and a good pair of boots before going out in the weather" was followed here. There was an impermeable stone water table up to two feet to prevent rising damp or backsplashing as well as extended eaves to prevent the possibility of streaming water that might erode or discolour the stucco finish. Very smart application of embedded traditional wisdom as this part of the country can have some brutal winter and spring weather including blizzards, ice, sleet and heavy rains.

Hand Carved Islamic Dome

Included in our commission was the design, construction and installation of an enriched plaster dome of Islamic geometric design for the "mihrab" or private chapel of the owners who presented me with a rendering of an hexadecagram, a 16-sided star polygon as a point of departure for the design. The first challenge was to determine the surface to receive the design, to research what kind of curvature for the dome was possible given the architectural constraints of the room height, the potentially obstructing rafters above and even the thickness of the dome itself. We managed to squeeze out the most curvature possible with a profile generated by a three-centred arch, an approximate ellipse.

The hexadecagram pattern could now be adapted for the determined surface. This was all carried out traditionally, geometrically with compass and rule. The initially provided design was modified, the proportions of the 'safts' or petals of the star-like tessellation were adjusted to produce a more harmonious composition and the entire pattern was reduced in scale so as to be fully observable from a prostrate position on the ground. A calligraphic element, "ﷲ‬, Allah" was placed in the direction of Mecca to provide orientation for prayer.

Translating the interlaced pattern from a scaled two dimensional drawing to the three dimensional surface of the dome was another important step involving more geometry. The dome was to be cast; this meant that the "void" had to be first extruded in plaster. Onto that inverted surface the pattern was carefully and methodically transferred, physically inscribed utilising several methods to verify its precision. This accomplished, the casting of the dome in a relatively thin shell of plaster could commence.

Islamic geometry participates in a  universal tradition of sacred geometry. Principles of the sacred feminine in harmonious relation with the sacred masculine were intrinsic characteristics of the tessellated dome that I sought to augment. For example, the "void" of the dome can point to the vault of heaven but has a perhaps stronger correlation with the universal "womb", the unseen and unknown mystery out of which all emerges. Rather than being considered empty or being nothing, the void symbolises that which is as of yet undifferentiated...potential itself. The gentleness and ethereal nature of the void is contrasted with the rigourous order, the imposed and revealed pattern of the tessellation.

For the enrichment of the surface we chose to further accentuate these principles of softness/sharpness, darkness/light, the sacred feminine and masculine. The oculus at centre surrounds a lightwell, literally bringing the light of the sun to be the focal point of the design. The tessellation continues to emanate from there in successive waves. The sixteen pointed star received a soft dimpled pattern representative of the sacred feminine, next contrasted by the sharp "flamed" texture hand gouged with wood chisels. The safts of the tessellation were so proportioned as to provide balance between these soft/hard, feminine/masculine elements. The end result is an harmonious composition that takes disparate, contrasting elements and interlaces them together into its own symbolic "universe", a single turn of the divine compass, encompassing quite literally the sacred feminine and masculine, seen through the symbol of unity, the perimeter of the circle through which it is entered.
