What is it to think the planet? What forms of thought are adequate to the task?

One answer: Planetarity as philosophical engineering. Earlier this year, I spent many a month on a planetarity syllabus that culminated in habitability as the core concept of my inquiry into planetarity. Having taken a break, I want to revisit the term “philosophical engineering” with the intent of replacing it with a new term that not only encompasses philosophical engineering, but also methods from design and speculation, and the use of new cognitive technologies, i.e., AI as Augmented Intelligence.

That term is Epistry.

Aside: I have been playing with that term, with more or less the same meaning that I am using here, for over a decade now, with this essay in particular being quite close to my current usage. Epistry is philosophy for a synthetic age, where we don’t just study the world, but make it. Or to put it in computational terms:

Epistry is philosophy when it becomes executable.

In this new adventure of abstraction, we aren’t abstracting away from the world, but rather, abstracting into the world. That is how philosophy becomes executable. In my mind, Epistry is an Aristotelian + Nagarjunian mode of intellectual being. They are the second most important thinkers (after Plato for Aristotle, and the Buddha for Nagarjuna) in their respective intellectual tradition, but that’s a plus.

At the risk of being reductive, Aristotle inspires my head, while Nagarjuna touches my heart. Their fusion makes for a vibe, a mood, an atmosphere more than a theory or a doctrine that I hope the second-in-commands would approve and adopt if they were alive today. But A & N are distant gods, Mahadevatas, and it’s always good to have some local guides, the Ishtadevatas who bless our pilgrimage.

Here are a few nearby minds who continue to inspire me: (in no particular order): Daniel Dennett, Douglas Hofstader, Christopher Alexander, D’Arcy Thompson, Nassim Nicholas Taleb, Francisco Varela, J.J. Gibson, Jakob von Uexkull....If I had to think of a concrete step I want to take that goes beyond these Ishtadevatas, it’s that the epistrator has to engage deeply with the process of technology creation, especially technology that serves as infrastructure for doing science.

TLDR; I am restarting my investigation of habitability; expect one long, deeply researched essay - likely split into two parts - every month. While this essay is being published in July, I am counting it as my essay for August, so you will see the next habitability essay in September.

Habitability

The planet is the ‘first object’ of epistry (that should remind you of Aristotelian first philosophy and the unmoved mover as its first object…). Planetarity is the planet ~~thought as philosophy~~ thought as epistry - i.e., planetary thinking that extends seamlessly into the making of the planet; not just by human beings, but by all living beings. And within that thinking of the planet as first object, habitability becomes the first concept, the central concern of ~~philosophical engineering~~ planetary epistry.

What does that reorientation look like? Too early to tell, but over the next few months, I am going to revisit the planetarity syllabus reframed around habitability.

When I started working on the planetarity syllabus, I was reading and writing my way through entanglements of governance, time, and space, trying to figure out the contours of our planetary condition. I didn’t know that habitability was the destination until I arrived there. But now looking back at the territory that has been surveyed: it’s time to draw a map. In this second iteration, we are not going to meander toward habitability; we are going to start with it.

Thanks for reading Ranganaut! Subscribe for free to receive new posts and support my work.

Round two has two foundational commitments. The first is that planetarity is, fundamentally, ~~a species of philosophical engineering~~ a species of epistry. We are composing concepts, protocols, institutions, and artifacts because, in our planetary condition, the earth is known through instruments and governed through executable code. Understanding the world and intervening in it should fuse into a continuum. If the first two acts of the play of epistry were about the Hegelian idea of philosophy being its own time apprehended in thought and the Marxian idea of changing the world rather than studying it, then the third act is to engineer the concepts and the code that will allow all beings to flourish in the Anthropocene.

The second commitment is to the planet as the first object and habitability as the first concept of planetary epistry (note that concepts here aren’t abstractions - they have to be executable, like any other aspect of epistry). We usually think of habitability as an astrobiological concept - conditions that a planet needs to satisfy before it can teem with life. A rock in the Goldilocks zone, some liquid water, an atmosphere, and abracadabra, life happens. I am no expert on the origins of life, but as far as I can tell, habitability is not a given; it is a relational, metabolic, planetary achievement. In the autopoietic conception of life, it is an ongoing, dynamic process at many scales - living systems both produce and reproduce themselves.

Our technologies should be in service of this planetary autopoiesis. The maintenance of this planetary metabolic order is our primary collective task as a species.

As an intellectual commitment that’s grounded in material practice, habitability will not be achieved or squandered at the level of abstract moral belief, but at the level of protocol. In order to engineer this metabolic achievement, we have to address the design challenges posed by the three themes I covered in the planetarity syllabus: Governance, Time, and Space, but before I get to those themes, a few words on the method behind the madness.

A Pattern Language for Habitability

If our investigation of habitability is to be a manual of epistry rather than a sequence of arguments, it needs a pattern language: recurring forms through which philosophical ideas encounter the world, acquire structure, and be tested in practice. Four patterns will recur throughout these essays, each placing the reader in a different role: witness, constituent, rule-maker, and inhabitant.

Witness: Field Note.

Consider the room in which you are reading this essay. What electricity keeps the screen lit and the air at a tolerable temperature? Which watershed supplies the building? What materials, organisms, infrastructures, and forms of labor keep the room functioning? Where do its heat and waste go? For which beings is this environment habitable, and for which is it hostile? What protocols determine what happens when the electricity fails, or someone cannot pay the water bill?

When seen via the pattern, every room turns out to be a planetary fractal. Inside it are power stations, reservoirs, mines, forests, microbes, supply chains, maintenance workers, financial systems, atmospheric processes, and histories of construction and extraction.

The Field Note pattern trains us to notice these relations. It asks us to cultivate a form of planetary attention, the ability to perceive habitability as an ongoing accomplishment instead of a passive background.

The field note is a combination of actual field work - say, walking outside the door to see who is laying a pipe - and metaphorical journeys to rare earth mines in China to see who is purifying neodynium for the car plugged into your wall socket.

Constituent: Institutional Prototype.

This pattern begins with a philosophical claim and asks what kind of institution would have to exist for that claim to acquire heft. If future beings deserve consideration, for example, what institution could give them standing in present decisions? One possible prototype might be a Ministry for the Distant Future, permitted to deliberate only on consequences unfolding more than a thousand years from now.

Ministry for X is an institutional prototype pattern for many futures/alternatives.

Who would constitute the ministry and how would it acquire knowledge of distant futures? What authority would it possess? How can its decisions be contested by those alive today, and by our successors? How could it speak for people and species that do not yet exist without simply projecting present values onto them? Under what conditions should it be revised, or dissolved?

The Institutional Prototype convenes the actors, forms of knowledge, sensing capacities, rights, obligations, and limits that collective action requires. The term agency has two common meanings - our agency as individuals or collectives to change the world to suit our needs, and institutions that serves a collective purpose, like the now defunct ‘US Agency for International Development’, USAID. The institutional pattern combines the two agencies into one, while asking the question: what kind of agency would make this philosophical claim actionable?

Rule-Maker: Draft Protocol.

Institutions make agency possible; protocols make agency actual. which is to say, protocols operationalize the agency that institutions convene. A protocol specifies what a system can sense, which participants it recognizes, how it responds to particular signals, what actions follow, and how its decisions can be challenged or revised.

Imagine, for instance, an interspecies carbon currency (carbon being the element that makes life possible) through which humans exchange value with other forms of life, and even more speculatively, other forms of life start trading with one another. Designing such a currency immediately raises many questions such as:

1. What would count as participation by a forest, a pollinator, or a microbe?

2. How to translate their activity into a signal the carbon currency system can recognize?

3. How would we compile the traded activity into a biochemical signal that could be read by cellular processes and potentially encoded in DNA?

4. Would such a currency enable reciprocity, or merely extend the market’s power to commodify life?

5. Could another species refuse to participate?

6. What happens when the relevant signals are ambiguous, manipulated, or entirely unintelligible to us?

Let’s wear a designerly hat and look at this protocol more closely.

Protocols: Carbon Currency Case Study

Carbon is the element that makes earthly life possible. An interspecies carbon currency is a medium of exchange grounded in carbon. Its basic unit would not represent carbon in the abstract, but as a verified metabolic event: carbon fixed, transferred, transformed, stored, or released under specified ecological conditions.

Such a currency would have to pass through several worlds/umwelts. An ecological activity, say, photosynthesis by a plant, methane oxidation by a microbial community, or the transfer of sugars from a tree to a mycorrhizal fungus - would first need to generate a biochemical signal. A cellular sensor could detect that signal and activate a CRISPR-based molecular recorder. CRISPR would function as the protocol’s writing mechanism, making a defined alteration in a designated region of DNA.

The DNA sequence might encode several features of the exchange: the kind of carbon transformation, the identities or classes of the participants, its approximate magnitude or duration, the conditions under which it occurred, and its position within a sequence of earlier transactions.

CRISPR is the inscription instrument; DNA the durable ledger.

Trade between organisms will therefore leave complementary records. If a plant transfers carbon-rich sugars to a fungus and receives phosphorus in return, molecular signals associated with the exchange would trigger different inscriptions in engineered sentinel cells positioned at the interface. One record would attest to the carbon transfer; another to the reciprocal nutrient flow. Like with the blockchain, neither inscription alone would constitute the transaction. The trade would be recognized only when the protocol detected a corresponding pair of events.

Once a particular trade or threshold had been inscribed in DNA, the altered genetic state might change what a participating cell does next: release a nutrient, produce a signal legible to another organism, activate a protective function, or acquire access to a shared resource. The ledger becomes more than an archive; it would operate as a biological contract in which past exchanges alter the conditions of future ones.

I could then collect DNA samples across an ecosystem to translate these molecular records into human-legible institutions. A verified inscription might trigger the release of funds for habitat restoration, impose an obligation upon an extractive actor, or allocate resources to the maintenance of the ecological community that produced the value.

The DNA inscription is evidence that a cell registered a signal, but by itself, it’s not proof that an ecosystem flourished, that carbon remained stored, or that another species consented to the exchange. Ecological observations, carbon-flux measurements, durability assessments, and multiple biological witnesses would still be required.

In short: the carbon ledger makes a multispecies economy and democracy possible, but much work will be needed to make sure organisms are consenting to the trade (can a bacterium in my blood consent to being ingested by a white blood cell?). The currency could enable organisms to become participants in a shared economy, or it could turn them into involuntary accountants for a human one. The currency must therefore preserve the capacity of living systems to remain illegible, to interrupt the transaction, and to refuse it.

Giving a concept executable form does not end philosophical inquiry; ideally, it gives philosophy skin in the game.

Inhabitant: Speculative World.

A speculative world is an imaginary environment in which institutions, protocols, technologies, organisms, and everyday practices have been assembled into a possible form of life. It asks the reader to inhabit the world an idea might produce, not just evaluate that idea from the outside.

A multispecies home, for example, would not be a human house decorated with bird feeders and insect hotels. It would recognize several species as first-class inhabitants. Its light, temperature, acoustics, surfaces, circulation routes, appliances, and rhythms would be designed around their differing needs.

Inhabiting such a home would quickly reveal conflicts. What happens when the temperature one species prefers is intolerable to another? How are predators and prey accommodated? Who decides which forms of reproduction, contamination, noise, decomposition, or death belong inside the home?

The Speculative World is not a utopia; it is an integration environment, a place where philosophical commitments, institutional arrangements, and operational protocols meet one another’s consequences.

The Grammar of Habitability

Witnessing, Constituting, Rule-making and Inhabiting: together, the four artifacts describe a movement:

1. The Field Note discovers a world.

2. The Institutional Prototype convenes a world.

3. The Draft Protocol regulates a world.

4. The Speculative World lets us inhabit and contest the world they produce together.

This movement is a circle, not a line. After entering a speculative world, we return to the existing one with altered senses. We notice relations that had appeared as background. We find exclusions our institutions concealed, consequences our protocols erased, and forms of life our imagined futures failed to accommodate. Inhabiting returns us to discovery, and the cycle begins again.

These artifacts will recur throughout the three principal themes that I am going to cover - governance, time, and space - and together they form a design language for turning habitability from an idea about the world into a practice of making worlds habitable.

The First Design Problem: Governance (Who maintains habitability?)

If you are reading this on a screen, inside a temperature-controlled room (I am), you are insulated from the vagaries of the flesh by an interlocking series of technological systems. We have built a technosphere that extracts energy, processes information, and spits out waste at a planetary scale. Think of Benjamin Bratton’s concept of “The Stack” - the accidental, planetary-scale megamachine of computation that is currently terraforming the Earth.

The problem is that the Stack, and the globalized capitalist system it serves, is completely indifferent to habitability. It operates in the register of the Globe, a human-centric construct that views the Earth merely as a backdrop for trade and extraction. But we don’t live on a Globe. We live on a Planet, a deeply entangled biophysical system.

So, who should maintain the metabolic order of the Planet?

It certainly can’t be the traditional nation-state. The nation-state is a geographic and juridical fiction completely mismatched to the scale of atmospheric carbon or ocean acidification. Planetary governance requires us to move past the idea that humans are the only actors that matter. Perhaps the solution is Gilman and Blake’s idea of “Planetary Subsidiarity” - a system of governance that embeds reciprocity, decentralization, and multispecies justice. However we do it, we have to learn to govern not as masters of a passive rock, but as self-conscious organs of a living planet. We need new epistries for this: the Elephant who holds the memory of the whole, the Architect who designs the institutional rooms for new forms of life to gather, and the Connector who maintains the relational networks across species and timescales.

The Second Design Problem: Time (Across what durations do we maintain it?)

We have a massive temporal contradiction at the heart of our planetary condition. Human political and economic cycles operate on scales of days, quarters, and four-year election terms. But the hyperproblems we face - like climate change or ecological collapse - operate on geological scales.

If we are to engineer habitability, we have to grapple with the “Planetary Durée.” This requires a radical expansion of our temporal imagination. As the geologist Marcia Bjornerud points out, we suffer from ‘time-illiteracy.’ We have to cultivate ‘timefulness’ - an awareness of deep time. We need to look at the Earth not just as a snapshot of the present, but as a vast, unfolding text, the book of the world.

In this context, our cognition, our sensor networks, our climate models, and our artificial intelligence are not unnatural aberrations. They are the planet thinking itself in rapid time that’s embedded in geological time. We are the means by which the Earth has become aware of its own deep duration. But this also means we are responsible for designing and executing institutions, protocols, and legal frameworks that can respect a polytemporal reality.

How do you write a constitution that protects the habitability of the planet for a species that won’t exist for another million years?

How do you design for deep time? This is where the Ministry for the Distant Future might help concentrate our imagination.

The Third Design Problem: Space (In the face of what otherness?)

When we expand our view of governance and time, we inevitably crash into the problem of Space, or what I called “Planetary Alterity.” For the last few centuries, the Western, now Global, project has been one of reducing the world to a known, mapped, and exploitable grid. But as we transition from the Globe to the Planet, we discover that the Earth is profoundly alien to us. As Gayatri Spivak notes, the planet is in the species of alterity, it belongs to another system. It is unmasterable. We inhabit it ‘on loan.’

We see this alterity when we look up at exoplanets, realizing how bizarre and varied the universe’s planetary zoo really is. But we also see it when we look down into the soil, or into the abyssal oceans, or even into our own microbiomes. We are surrounded by non-human actors - fungi, bacteria, weather systems, forests - that all have their own Umwelt, their own bubble of perception and meaning. They are terraforming the Earth right alongside us.

Another project of mine (also on Substack), the Cellosophy project, is a focused exploration of the alien umwelts that cohabit the earth.

To take planetary space seriously is to abandon the disembodied cosmic eagle view that treats the Earth as a fragile blue marble to be managed from above. Instead, we need the perspective of the cosmic earthworm: embedded, intimate, crawling through the dirt, acutely aware of its entanglement with the immediate, messy, alien realities of the biosphere.

Terraforming for Habitability

Usually, when we hear of terraforming, we think of science fiction (Expanse is really good!), or Elon Musk blasting nukes over the poles of Mars to create an atmosphere. But the truth is much closer home, for we have been terraforming the Earth for centuries through agriculture, industrialization, and carbon emissions. It’s just that our current terraforming project, aka, the Globe, is accidental, blind, and suicidal.

The question is not whether we will terraform the Earth; we are already doing it. The question is whether we can terraform it intentionally, with an ethics of care and reciprocity for all beings (what I called Mahayanics).

However, the recognition of our responsibility has to go hand in hand with humility, because the Earth has always been terraformed by life. Cyanobacteria were the OG epistrators, terraforming the planet billions of years ago by pumping it full of toxic oxygen, forcing a massive extinction and paving the way for complex life. The biosphere is an autopoietic, self-making system. Our job is not to retreat into a fantasy of pristine, untouched nature, for that’s the cosmic eagle speaking, but to accept our species-dharma as the cosmic earthworm.

We must use our technological power, our planetary sapience, and our deep time historical consciousness not to conquer nature, but to embed ourselves gracefully within it. We have to design the bio-futures of our terrestrial habitats so that they support the flourishing of the multitude.

This is the task of planetary epistry.

Over the next few months, I am going to build out this framework, a reworking of the planetarity syllabus as a manual of habitability. We will reread the deep history of the Earth as Bjornerud and Chakrabarty put it, reparse the cybernetics of the Stack, and take another look at the stars to understand the ground beneath our feet.

We must embrace our role as conscious, active, and deeply entangled participants, recognizing that our future as a species depends on our ability to terraform a world where life can flourish.

Starting in September 😛

TLDR; Monkey Goes East restarted as ‘Sinosophy’; expect monthly essays.

There’s a famous definition of philosophy by Wilfrid Sellars, where he says that it aims ‘to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term.’ If you’re a philosopher in this sense, you have a theory of how things in the broadest possible sense of the term hang together in the broadest possible sense of the term. That’s a positive conception of philosophy, philosophy that leads to doctrines and theories and systems. Maybe Sellars’ version is closest to it being a thought-system?

But there’s also an alternative approach to philosophy, which makes it look more like art or poetry. It’s philosophy channeled as a mood or as an atmosphere. And in the last couple of hundred years, that is the way moderners have often experienced non-Western philosophy. When we encounter Oriental philosophy - and I’m using that pejorative term deliberately - we typically encounter it in spiritualist terms, as a way of life, and not a specific theory of how the world hangs together.

The spiritualist, ‘way of life’ label was eagerly embraced by many traditionalists themselves, who were colonial subjects demeaned and dominated by Western intellectual and scientific traditions. In response, they said: “Oh, well, those guys are better about the nature of matter, but we still have monopoly over the spiritual life, and our philosophy is way better as lived philosophy than anything these scientized and alienated westerners are offering.” I don’t want to get into a debate about this being the right way to position yourself against a dominant tradition, but I see these attempts at casting Indian or Chinese or Japanese philosophy as a way of life or a spiritual philosophy - say, in the way we consume Talks with Ramana Maharshi, I am That, or the way Alan Watts wrote as a western interpreter of East Asian traditions, or Shunryu Suzuki‘s Zen Mind, Beginner’s Mind as an example of the East coming West - as conveying a mood or an atmosphere generated by a tradition rather than an exposition of its doctrines. The rebels against this atmospheric cause were all professors - people like Bimal Matilal who wanted to teach Indian philosophy at Oxford or Harvard in the philosophy department, and that required penance to show how rigorous and rational Indian philosophy has been over the ages.

But rigor has the stench of rigor mortis; after enormous labor, you are allowed to give a talk in some minor section of the American Philosophical Association’s annual conference. The woke have left you behind as too brahminical, and the philosophers reading Kripke for the 35th time weren’t going to let you teach logic to their students were they? And don’t even talk to me about those making outlandish claims about spaceships and plastic surgery in the Vedas.

In contrast, the atmosphere generated by these traditions has a lot of staying power; their influence continues much after the end of decolonization. It’s now shading into Chinamaxxing as the Middle Kingdom becomes the Middle Kingdom once again. Which small town in New England or California doesn’t have a Yoga Studio? If you own an iPhone you hold an object congealed from that atmosphere. Some of this influence is attributed to Indian or Chinese or Japanese culture - their musical, film-making or culinary traditions, for example - but a lot of culture itself is an atmospheric thing, isn’t it? I will continue insisting that the mood has a philosophical core, and, in that sense, the mood has traveled a lot further than any doctrine with a linear, identifiable connection to Asian philosophical traditions.

Hypothesis: for traditions that don’t have a clear historical connection to the modern world, it’s better to evoke them as a mood or an atmosphere than as defensible theory. That may be a harder task than arguing for the truth of their doctrines, because, if anything, the atmosphere of the West is even more dominant than its ideologies and doctrines.

All to say that my reading of Chinese thinkers and traditions is going to evoke a mood (a bouquet of ‘ways’) and I will not make truth claims about what those philosophers, writers and texts are saying. I’m not going to read them that way at all. I’m going to read them in the way that an artist would, the way Joyce read Homer or even as how Nolan has brought Homer to our screens than how Emily Wilson has chosen to translate the Iliad or the Odyssey.

Reading Chuang Tzu creatively isn’t a license to be arbitrary. Joyce was not accountable to Homeric philology, but he was ferociously accountable to something, and that something was the atmosphere of the Odyssey: the shape of a day, the way a wanderer’s mind keeps arriving in rooms he has already left. You can get a mood wrong. A person who lives inside that mood feels the wrongness immediately, even if they can’t point to the line where you went off. Suspension of disbelief is the standard I want to be held to.

The Atmosphere of Habitability

In January I called this “The Monkey Goes East.” Confucian Asia - Japan first, then South Korea and Taiwan, then China, with Singapore and Hong Kong as instructive cousins - has produced a form of modern existence that we keep describing in borrowed terms. We club Meiji with Hiroshima and then with the American security umbrella. We file China under the communist revolution and its aftermath. That carving up worked while we all lived inside the Liberal International Order and it works badly now that we don’t. I wanted to look at the period from Meiji onward as though it had its own logic, its own drivers, its own principles, and to do it with the metabology I stumbled into last year while reading Machiavelli in a planetary frame.

Kaiser Kuo and Adam Tooze supplied the provocation that China is the master key to understanding the future of modernity. But these days I am a one-trick pony, and everything I think and write about has to do with the planet in some fashion. China may not be the master key to understanding Planetarity, but it’s an essential key nevertheless, and Sinosophy is the atmospheric counterpart to the analytic investigation of Habitability I restarted a couple of weeks.

Habitability, as I set it up a couple of weeks ago, asks three questions. Who maintains the metabolic order, across what durations, and in the face of what otherness. Those are engineering questions and I want them answered in protocols. But each of them has an atmospheric background, which is the question of what it feels like to live inside a planetary order. Sinosophy is going to work in that background.

Sinosophy: Planetarity with Chinese Characteristics.

PS:“With Chinese characteristics” is Deng’s formula for swallowing a foreign universal without asking the original owners for permission, and then daring anyone to say the result isn’t the real thing. “Socialism with Chinese characteristics.” It’s ideological metabolism: something comes in from outside, gets broken down, and comes out as fresh conceptual muscle. Planetarity is my reigning universal, and I want to see what happens when it’s digested by China. The Chinese planet doesn’t have to be the same as the American planet…

There’s an ancient precedent. Qi 氣 gets translated as vital energy, which is how it ends up in wellness brochures next to yoga mats, but the character also connotes steam, breath, air, weather. Qi is atmosphere in the literal sense before its atmosphere in the figurative one. And the vernacular art built on it, Feng Shui, wind and water, is a body of practice about where to put a house given the slope of the land, the direction the cold comes from, the way water moves and where it pools. A pattern language for habitability, roughly two thousand years older than Christopher Alexander’s (though if you read his “Timeless Way of Building,” you will see the Chinese inspiration). ‘Prana’ in Sanskrit has some of the same resonances, connecting breath, atmosphere, animality and life.

I’m not going to claim Feng Shui works, no more so than I am going to claim Vastu works or Ayurveda is better than Allopathy. I don’t know whether it works and I’m not equipped to find out. I am quite fine with admitting that Ayurvedic remedies often haven’t been validated in clinical trials. What interests me is that a civilization built a transmissible, quasi-technical practice whose whole subject is the habitability of a site, and built it without a concept of nature standing in contrast to a concept of society. The house, the hill, the prevailing wind and the dead ancestors sit in one system.

Journey to the West is a road story in which the road is populated by beings who are not human, sometimes demonic, and mostly indifferent to the monk’s errand. Mountains that object to being crossed. Rivers with residents. A landscape you negotiate with rather than traverse. Spivak says the planet is in the species of alterity and we inhabit it on loan. The Monkey knows that in his bones, and keeps reminding the monk about it.

The Yang of Habitability has many patterns - instruments for making a concept executable such as the Field Note, the Institutional Prototype, the Draft Protocol and the Speculative World. The Yin of Sinosophy approaches the same problems of Governance, Time and Space, and Alterity without adding atmospheric patterns. I’m suspicious of my urge to invent patterns, because the moment I do, I’ve turned a mood into a system, but I am open to the possibility that such a Sisyphean task is part of the deal.

Downside: I don’t know whether this atmosphere is believable. I might end up assembling a flattering mood, call it a Confucian Planetarity, and end up with a pitiful version of Chinamaxxing. A person born and brought up in China should be able to read this without wincing, even while thinking I’ve got every detail wrong.

Monthly, then, alternating with habitability. An essay that engineers followed by an essay that evokes. Xuanzang went west and came back with sutras that took the rest of his life to translate. I’m going the other way without the Tang emperor paying for my travels. No sutras. I’ll settle for a few weather reports.

The eaves have their own entrance, a gapped soffit too narrow for anything but the bats that use it, and the porch light on that side of the house runs on a schedule keyed to their flight times, not to whoever's coming home late. Under the kitchen, a mycorrhizal mat the foundation was designed around rather than simply poured through, tied by root and hypha to the three fruit trees out back — the concrete has a deliberate gap in it, patched with mesh, for exactly this reason. Mason bees have a block of drilled timber bolted to the fence, replaced every few seasons. A compost column runs floor to roof through the utility wing, load-bearing, feeding the trees and taking the kitchen's waste both at once.

The charter is short and gets revised more than it gets read. It says what happens when the resident owl's hunting hours conflict with the housecat's feeding schedule — the cat eats indoors after dusk, no exceptions, and the humans stopped fighting that rule once the second owl arrived. It says where death happens: a decomposition closet off the utility wing, not the trash chute, because death indoors is planned for, the body returned to the soil, not bagged and put at the curb. It says who gets a vote on the zones and who just gets a voice — the humans, the bats, and the trees get votes, roughly speaking, cast by people who've learned to read what each of them needs; the cat does not, and knows it, and resents it in the ordinary way cats resent things.

None of this reads to the family as an argument. The eleven-year-old's homework this week is a floor plan of the house with every non-human resident labelled, due Thursday, ordinary as a worksheet about the water cycle. Nobody in the house is making a case for cohabitation. It's just how the house works, the way a thermostat used to be one number instead of six, before anyone here remembers it being otherwise.

1. Recognition. Any polity — a state, a city, a river basin governed jointly, a corporation operating a bounded territory — may hold Metabolic Standing over the specific systems it maintains: an aquifer, a soil horizon, breathable air, a fishery, a forest's regeneration rate. Standing is granted per system, never once and for all. A government can hold standing over its water table and be in default on its coastline in the same year.

2. Threshold. Each system carries a maintenance threshold set from the best available earth-systems evidence, re-set on a fixed interval, never by the polity being measured. Falling short of a threshold is not a crime and carries no fine. It is a fact, dated and made public.

3. Certification. A certifying body — independent, plural, no single seat empowered to certify alone — reviews each system against its threshold on a public schedule. Certification is binary, per system: held, or lapsed. No system holds lapsed certification for more than four intervals without a filed remediation plan.

4. Notice. A lapse triggers notice, not seizure. The polity in default gets one full interval to remediate, appeal, or contest the threshold itself before any consequence attaches.

5. Revocation. Standing that lapses past its remediation window is withdrawn — for that system only. Withdrawal does not transfer the system to another sovereign, dissolve the polity, or authorise invasion, annexation, or occupation under any framing whatsoever. What it withdraws is the polity's exclusive claim to decide that one system's future; the decision passes, for that system alone, to whatever body the certifying process names as trustee until standing is restored.

6. Restoration. Standing is restored automatically the interval after a system clears its threshold again — no petition required. The protocol is built to be recovered from, not to punish permanently. A sovereign that loses standing over its rivers and fixes its rivers gets its rivers back.

7. Refusal. A polity may decline certification entirely, for some or all of its systems. Refusal is not a violation — it is simply the polity declining to claim that its authority rests on maintenance. It forfeits nothing by refusing except the ability to say later that it was certified.

What this protocol does not do matters enough to say plainly rather than leave to be inferred: it does not create a body empowered to invade a failing state in the name of its rivers. The two most dangerous readings of "sovereignty conditioned on habitability" both run straight through that omission, and both are refused here on purpose. A certifying body of the kind this protocol needs would be a close relative of The Ministry for the Distant Future — built for maintenance instead of deep time, but answerable to the same discipline: power to certify, none to seize.

The Ministry hears nothing that resolves inside a thousand years. If a consequence can be traced to a policy, a species, a coastline, a language, and it plays out fully within that horizon, it belongs to some other body — a court, a legislature, a protocol's own appeal clause. The Ministry's docket starts where every other institution's foresight already runs out.

Composition

No elected seats. Nobody now living will be alive to be held accountable by the future they ruled on, so accountability has to be engineered some other way. Three benches sit in rotation rather than one standing panel. A geological bench — paleoclimatologists, stratigraphers, people who read ice cores and sediment the way lawyers read precedent. An actuarial bench — the same discipline that prices pandemics and asteroid strikes, retrained on hundred-generation horizons instead of ten-year ones. And a kaitiaki bench, seated by rotation from institutions that already practise long-duration guardianship, because thousand-year stewardship isn't hypothetical — a few places have been doing it, imperfectly, for a while. The River That Sued is one such precedent the bench would draw on: not a thousand years yet, but running on the right kind of authority.

Powers

The Ministry cannot legislate, appropriate funds, or hold territory. It has exactly one power: to certify or withhold certification from any policy, protocol, or institution that claims a benefit lasting past the thousand-year horizon. Withheld certification doesn't block anything. It strips the claim. A dam gets built with or without the Ministry's blessing — it just doesn't get to call itself a legacy without it.

Contestation

Every certification decision publishes its full reasoning, dissent included, and any bench member can force a re-hearing once new stratigraphic or actuarial evidence crosses a stated threshold. The Ministry can be wrong. It gets checked by more time passing, which is the one resource it cannot manufacture on demand.

Sunset

The Ministry dissolves automatically every twenty-five years and must be re-founded by whatever bodies empowered it the first time. A thousand-year mandate held by an institution that never has to ask permission again isn't a ministry for the future. It's a sovereign wearing the future's face.

China accounts for roughly 70% of global rare-earth mining, which is the number everyone quotes and the least decisive one. The number that matters is downstream: 85–90% of global processing capacity, and for the heavier rare earths, 98–99% of separation capacity. The chokepoint isn't the hole in the ground. It's the refinery.

A large share of that ore comes from around Bayan Obo, in Inner Mongolia — the largest known rare-earth deposit on the planet — and gets refined nearby at Baotou. Since 1965, Baotou Steel's refineries have pumped their tailings into a purpose-built dam outside the city: a circular embankment now 11.5 kilometres around, engineered to eventually hold close to 234 million cubic metres of black slurry. People who've filmed it call it a lake — a kind word for it, but I take the point; "tailings dam" doesn't convey the scale nearly as well. Chinese authorities confirmed in 2016 that farmland around it had been contaminated, and researchers have documented crop losses and health complaints in the villages nearby for years before that.

Draw the boundary correctly and that lake is the actual size of a vibration motor. Nobody signed a permit that read "flood this floodplain so a phone can buzz quietly in a pocket on the other side of the planet." The technosphere doesn't move through permits like that. It moves through several billion small, unrelated purchases, and the backward trace was never one I was asked to make at the register, any more than anyone else is.

This is the field-note discipline at its plainest, and it cost me one evening with a search engine, not a research grant: not a metaphor about interconnection, an actual supply chain, followed one link at a time until it stops being abstract. Nothing currently prices that lake into the sale. Metabolic Standing is one sketch of an instrument that would have to.

Behind that sentence is a long petition. Whanganui iwi chiefs first brought the claim to Parliament in 1873. Their descendants kept bringing it — through a river-boards act in 1891, a scheme in the 1930s that delivered nothing, the Waitangi Tribunal in the 1990s, and eight further years of negotiation — for 140 years across five generations before the 2017 settlement closed the file. A person had to sue for its own personhood for longer than most of the humans doing the suing were alive.

The Act doesn't give the river's water a lawyer. It creates Te Pou Tupua: two guardians, one appointed by Whanganui iwi, one by the Crown, who act jointly as the river's face in law. If the river needs to be a plaintiff, a defendant, or a party to a resource consent, Te Pou Tupua speaks for it. The whole framework compresses into a whakataukī plain enough to put on a sign at the river mouth — Ko au te awa, ko te awa ko au. I am the river, and the river is me.

What this is not, and it matters to say precisely: this is not a court that can find a river delinquent. Standing here runs one direction. The river cannot be sued, cannot default, cannot lose its personhood for silting a channel or flooding a paddock. What got engineered is representation, not obligation — a person now speaks for the river in disputes among humans over the river. Nobody has yet built the other half: an instrument in which the river's own maintenance of the water, the fish run, the reach, is the thing that gets checked, and, on failure, withdrawn from someone.

Metabolic Standing is a sketch of that other half. Whanganui is where you'd go to find out whether the first half is even buildable — a hundred and forty years, and it barely is. I don't know a faster route to the same place, and I've gone looking.

I am going to take a break from writing. Will be back in a few (weeks, maybe months) when the Monkey Goes East.

The universe is astonishing in so many ways. It’s really big. It’s really old. It started with the biggest bang ever. And to add to that litany of astonishment, there’s the fact that at least one corner of the universe has been inhabited for almost four billion years, and at least one of those creatures looks up at the sky and wonders why there’s anything at all. Out of the swirling chaos of hydrogen and helium forged in the furnace of the Big Bang, matter somehow arranged itself into complex, self-replicating patterns. It arranged itself into cells, then tissues, then nervous systems. Eventually, the universe produced creatures capable of looking back up at the night sky and wondering at the sheer improbability of their own existence. As the physicist Paul Davies has observed, we are the moment the universe wakes up to itself.

This capacity for wonder at the possibility of existence is the starting point for any serious inquiry into habitability. We cannot afford to take the existence of the world - or our presence within it - for granted. The condition of planetarity demands that we expand our philosophical imagination; it can no longer remain the humanistic discipline that it has been for a couple of millennia. We must start with the cosmos, ask questions about planetary habitability, delve into the deep geological history of the Earth, and finally arrive at the burning questions of the Anthropocene.

1. The Cosmic Prerequisite: Fine-Tuning and the Anthropic Principle

The most general setting for habitability is the universe itself. Before a planet can support life, the fundamental laws of physics must allow for the possibility of life. When physicists and cosmologists look at the basic parameters of our universe, they encounter an eerie reality: the universe appears suspiciously fine-tuned for the emergence of complexity.

If the laws of physics had been even slightly different, the universe would be a sterile void. If the strong nuclear force that binds atomic nuclei together were just a few percent weaker, the universe would contain nothing but hydrogen - no carbon, no oxygen, no nitrogen, and therefore no biology. If gravity were slightly stronger, stars would burn out in a matter of millions of years, leaving no time for evolution; if it were slightly weaker, matter would never coalesce into stars and galaxies at all. If the expansion rate of the universe immediately following the Big Bang had been altered by a fraction of a percent, the cosmos would have either rapidly collapsed back in on itself or expanded so fast that galaxies could never form.

In The Goldilocks Enigma, Paul Davies calls this the ultimate mystery of existence: why is the universe just right for life? This observation is formalized in cosmology as the Anthropic Principle. Explored exhaustively in John D. Barrow and Frank J. Tipler’s definitive 1986 tome, The Anthropic Cosmological Principle, the concept takes this idea of fine-tuning and pushes it to its logical conclusion.

In its Weak form, the Anthropic Principle is not much more than selection bias: we should not be surprised to observe that the universe’s physical constants are perfectly tuned for life, because if they were any different, we simply would not be here to observe them. We are bound to find ourselves in a Goldilocks universe because a non-habitable universe produces no astrophysicists or historians to document its sterility. The universe is the way it is because we exist.

However, the Strong Anthropic Principle proposes something far more radical: that the universe must possess those properties which allow life to develop within it at some stage in its history. This flips the narrative of life’s insignificance on its head. It suggests that while (as far as we know) living beings are a sideshow to the parade of galactic and stellar activity, observers such as living creatures are not byproducts but ontological prerequisites. If the cosmos is a Book of the World - to use the medieval metaphor we revived in our discussion of time - then the most striking feature of that book is that it’s produced specifically to allow for the existence of readers.

When we bring this cosmoanthropic perspective down to Earth, it fundamentally alters our understanding of planetarity. It suggests that habitability is not merely a lucky chemical accident; it is a profound cosmic property. Perhaps the physical universe is not an indifferent machine, its habitability is built into its architecture.

Note that while the Strong Anthropic Principle was first formulated to require observers like us, it doesn’t need to. Octopii will serve as well. Perhaps even bacteria.

2. The Planetary Sweet Spot: Exoplanets and the Goldilocks Zone

If the universe provides the foundational laws for habitability, it is in planets that we must seek environments that fulfil their promise. Having acknowledged that the universe permits life, and entertained the possibility that it necessarily does so, we must ask: what makes a specific planet habitable?

Astrobiologists looking for exoplanets will likely refer you to a standard checklist. To support life as we know it, a planet requires a rocky surface, a breathable atmosphere, the right cocktail of biogenic elements (carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur), and, most importantly, liquid water. This dictates the search for the circumstellar habitable zone - the orbital distance from a star where temperatures are not too hot (which would vaporize water) and not too cold (which would freeze it), but just right. This is the Goldilocks Zone.

For centuries, our understanding of this zone was limited to our own Solar System. But as we have learned from Chris Impey (Worlds Without End) and Joshua N. Winn (The Little Book of Exoplanets) emphasize, the universe is teeming with planets. We have gone from knowing of zero planets outside our solar system to cataloging over 5,000, with current statistics indicating there are more planets than stars in the Milky Way. Impey estimates there are roughly a thousand billion billion (10^21) potential biological experiments happening across the observable universe.

Winn points out that not only planets aplenty, they are bizarre and diverse from the point of view of our solar system. The exoplanet zoo includes hot Jupiters skimming the surfaces of their stars, rogue planets wandering the dark void without a sun, and planets orbiting two stars at once. The two most common types of planets found in the galaxy - super-Earths and mini-Neptunes - do not even exist in our own Solar System. Looking at this diversity, one must assume that every possible chemical reaction has been repeated many times in many places.

This exoplanetary perspective reinforces what I have called Planetary Alterity. The planet is alien. The universe is alien. But the great lesson we are yet to learn is: embrace that difference. We are not the measure of all things. Perhaps there are more forms of wisdom than we can imagine!

Locating a planet in the Goldilocks Zone is only the beginning of the story. Venus and Mars both sit near or within the habitable edges of our Sun, yet Venus is a runaway greenhouse hellscape capable of melting lead, and Mars is a frigid, irradiated desert. Habitability, is a relational concept, not a widget you can extrude out of a checklist of ingredients.

As Charles Langmuir and Wally Broecker detail in How to Build a Habitable Planet, a planet is not habitable simply because it possesses certain fixed properties; it is habitable because the complex relationships between its geological, atmospheric, chemical, and biological systems are mutually sustaining over geological timescales. Habitability is a dynamic condition that living systems actively produce just as much as they require.

Habitability is a metabolic achievement.

3. Deep History: The Great Oxygenation Event and the Paradox of Life

To understand this metabolic achievement, we must grasp the rhythms of the Earth, the Planetary Durée, the realization that the deep past is woven into modern landscapes, atmospheric chemistry, and our own DNA. The Earth has been inhabited for billions of years, but the circumstances of that habitability have shifted violently. The planet we inhabit today is not the planet that first birthed life. The Earth of the Hadean eon was a churning magma ocean; the Earth of the Cryogenian period was a solid ball of ice. If we were to step out of a time machine onto the Earth of three billion years ago, we would immediately suffocate.

Life did not simply adapt to a static, habitable rock; it engineered the rock to suit itself. For the first two billion years of Earth’s history, the biosphere consisted entirely of anaerobic microbes that lived without oxygen. Cyanobacteria were the first organisms capable of photosynthesis. These microscopic entities began harvesting energy from the sun, and in doing so, they released a highly reactive, toxic waste product into the oceans and the atmosphere.

That toxic waste product was oxygen.

What followed was the Great Oxygenation Event, arguably the most significant climate catastrophe in planetary history. As oxygen accumulated, it poisoned the vast majority of the anaerobic life forms that had dominated the Earth until then, driving the planet’s first mass extinction. Furthermore, the oxygen reacted with atmospheric methane (a potent greenhouse gas, the main ingredient in LNG, which is in short supply as a result of the Gulf War), scrubbing it from the air and plunging the planet into a deep, prolonged ice age.

The oxygen that sustains our bodies today - the air we take for granted with every breath - was originally a deadly pollutant that eradicated the Earth’s first inhabitants. Their death is our life. Nature is not a harmonious whole in static equilibrium. The Earth is a polytemporal tapestry, as Marcia Bjornerud calls it, marked by periods of immense biological disruption. Life is the ultimate terraformer. Over billions of years, the interplay of life and geology - through the carbon cycle, plate tectonics, and nitrogen fixation - has continuously regulated the Earth’s temperature and chemistry.

The habitability we enjoy today is the inherited legacy of billions of years of metabolic labor by non-human actors.

4. The Anthropocene: Securing the Metabolic Order

Making the connection between this deep geological history, including acknowledging our existence to planetary poisoners, and the contemporary moment is a key task of Planetarity. Today, human history and planetary history have violently collided as Dipesh Chakrabarty says. We have entered the Anthropocene (or the Capitalocene, if we focus on the economic drivers of this shift), an epoch in which human activity operates as a planetary-scale geophysical force.

Just as the cyanobacteria once altered the atmospheric chemistry of the planet through their collective metabolism, industrial civilization is currently altering the global climate by extracting and burning millions of years of fossilized sunshine. The Great Acceleration of the mid-twentieth century has pushed multiple planetary boundaries - climate change, biodiversity loss, nitrogen cycle disruption - into the danger zone.

I am guessing cyanobacteria did not poison the world out of malice. They were the winners in the game of natural selection (but what about that early world made their skills so powerful? Need to find out...). We, on the other hand, possess what Benjamin Bratton calls Planetary Sapience. Through our sprawling technosphere - our satellites, sensors, deep-ocean cables, and computational models - we have developed the capacity to read the Book of the World. We can measure the parts per million of carbon in the atmosphere; we can track the melting of the cryosphere in real-time.

We are aware of the metabolic disruption we are causing.

This brings us back to the contradiction that animates the condition of planetarity: the tension between the human-scaled Globe and the alien, deep-time Planet. Globalization treats the Earth as a frictionless grid for capital and trade, a standing reserve for human extraction. We assumed that the background habitability of the planet was a permanent given.

We now know this is a dangerous delusion.

As Dipesh Chakrabarty argues, the climate crisis has collapsed the distinction between human history and natural history. We can no longer pretend that the social order sits independently above the physical order. Biogeochemical stocks and flows are the conditions that make any society possible in the first place. Without stable climate patterns, functioning water cycles, and fertile soils, there’s no human drama, no Netflix and Chill.

Therefore, our primary collective task as a species is the deliberate maintenance of planetary metabolic order. Habitability is no longer a background assumption; it is something that must be secured through explicit acts of governance. We must move beyond abstract environmentalism and engage in what I call Philosophical Engineering, designing the protocols, legal frameworks, and cybernetic feedback loops that keep the planet in tune. As Jonathan Blake and Nils Gilman propose in Children of a Modest Star, we need institutions based on planetary subsidiarity, capable of governing biogeochemical cycles that laugh at national borders. We need a politics of deep time that acts as a trustee for the unborn and the non-human. We must transition from being planetary consumers to planetary stewards.

5. Conclusion: Habitability as the Central Concept of Planetarity

When we look at the condition of planetarity from the outside in - starting from the cosmic fine-tuning of the universe and arriving at the urgent climate politics of the present - we see that all our inquiries converge on habitability being the central concept of planetarity, one through which we can view the three previous concepts we engaged with: governance, time and space.

Through the Planetary Durée, we learned to subsume the frantic, spatialized clock-time of human history into the deep, slow rhythms of geological time. We realized that to govern effectively, we must become timeful ancestors. Through Planetary Alterity, we recognized that space is not a passive backdrop but an active, alien participant. We learned that to live on Earth is to inhabit a world that we share with a multitude of non-human kin. We rejected the fantasy of escaping to Mars, committing instead to the Bodhisattva’s vow for the Earth: to stay with the trouble of our damaged home.

And in our inquiry into Governance, we sought the architecture of institutions - the Stack, the planetary assemblies, the multi-level regulations - required to manage this complex reality. We realized that the philosopher-king of the polis must be replaced by the planetary steward of the biosphere.

Habitability is the umbrella concept under which all of these ideas come together.

It is the bridge between the cosmic and the intimate. It encompasses the astrobiologist calculating the orbital mechanics of a distant super-Earth, the geologist tracing the isotopic signatures of the Great Oxygenation Event, and the urban planner designing a biophilic city block that sustains multi-species flourishing. It merges the universal laws of physics with the subjective, lived Umwelt of every creature on Earth.

To grasp habitability through philosophical engineering (as Hegel might urge us if we were around) is to accept our species-dharma: that we can use our technological power and our historical consciousness not to conquer nature, but to embed ourselves gracefully within it. We are living in a universe that has graciously allowed us to exist. Our task now is to ensure that the unique, finely-tuned alignment of time, space, and life that makes this planet a home does not collapse under the weight of our arrogance.

We must become the architects of our own continued existence. And not only our own.

Endnote

Having written this essay, I am not sure what I will do next. I had promised a year’s worth of writing on the Planetarity Syllabus, but in my head, I have stumbled into a cavern that I need to explore more thoroughly before coming back to monthly topic-by-topic coverage.

I am thinking of coming back in a few months with a deeper exploration of habitability - it needs a sustained investigation, unlike this time, when I feel into it as I scratched beneath the surface of Time and Space.

BTW, to show how well habitability has been covered as a humanistic subject, I performed a simple n-gram search for “Philosophy of Society” versus “Philosophy of Habitability,” and here’s what I found:

There’s no record of anything like “Philosophy of Habitability” (just see the screenshot above) while new books on the philosophy of society are published every day. What a shame isn’t it? No society without habitability, right?

Anyway, round two in a few months time, but I am taking a break from the Planetarity Syllabus for now.

"A planet is not habitable simply because it possesses certain fixed properties; it is habitable because the complex relationships between its geological, atmospheric, chemical, and biological systems are mutually sustaining over geological timescales."

— Charles H. Langmuir and Wally Broecker, How to Build a Habitable Planet, quoted in the Planetarity Syllabus, Habitability Part II

Liquid water, the right distance from the right star, an atmosphere: the checklist version of habitability, and the one astrobiology spent decades refining before admitting its limits. Langmuir and Broecker's sentence quietly throws the checklist out. Habitability isn't a set of boxes a planet ticks once. It's a relationship between systems that has to keep holding, continuously, or it stops being true.

That's the sentence I've built this whole site to answer. A checklist can be inspected once and filed. A relationship that has to keep holding needs something that checks on a schedule, notices when it lapses, and knows what happens next. The Ministry for the Distant Future and Metabolic Standing are two different guesses of mine at what that something looks like.

The Principle of Habitability

Behind every contemporary anxiety about the future of the Earth (and of human civilization, whatever that might mean), is an existential question: what makes a planet livable? Not just for humans, not just for the present century, but for the full community of beings that constitute Earth’s living systems, across the vast scales of time that geological and biological history demands. That question is the question of habitability, and exploring its diverse manifestations requires a radical shift in how we perceive our place in the cosmos.

What makes a planet habitable?

If you ask an astrobiologist scanning the heavens for exoplanets with the potential for life, they will likely refer you to a checklist: liquid water, a breathable atmosphere, moderate temperatures, a rocky surface, and the right cocktail of biogenic elements. This is the search for the Goldilocks Zone - a planet not too hot, not too cold, but just right. But the astrobiologist isn’t our only consultant, for habitability as a planetary concept is far richer, more dynamic, and more philosophically demanding than any checklist can capture. It is not an accidental sweet spot in a solar system. At its core, habitability is a relational concept: a planet is habitable not because it possesses certain fixed, sterile properties, but because the complex relationships between its geological, atmospheric, chemical, and biological systems are mutually sustaining over time. Habitability is a condition that living systems produce just as much as they require.

It is, in other words, a metabolic achievement.

More speculatively, you might have heard of the Anthropic Principle. The Anthropic Principle takes this idea of metabolic achievement and pushes it to its ultimate logical conclusion, suggesting that the very laws of physics and the fundamental constants of the universe appear suspiciously fine-tuned to allow for the emergence of life and, eventually, observers like ourselves. It posits that we should not be surprised to find ourselves on a planet that is habitable, because if the universe were any other way - if the nuclear force were slightly weaker or the expansion rate of the Big Bang slightly faster - we simply would not be here to ask the question.

In its weak form, the principle is almost a tautology of selection bias: of course we inhabit a Goldilocks world, because a non-habitable world produces no historians to document its sterility. However, the Strong Anthropic Principle suggests something far more radical: that the universe must have those properties which allow life to develop within it at some stage in its history. This shifts the planet from being an accidental chemical reaction to a necessary ontological frame.

I am betting on the Strong version, but in the context of the planetary zoo - that the necessity of life goes hand in hand with a diversity of living contexts. If so, habitability is built into the universe. It’s a pretty wild bet, and how would we test it? A slightly weaker version is to take the necessity of habitability as a hypothesis and see what conclusions we might be able to draw and then refine the hypothesis further until we don’t need the original hypothesis anymore - we have downstream consequences that can themselves be viable starting points for empirical research.

I. Habitability as Metabology

Back to Earth: to understand habitability, we must situate it within the framework of metabology, the flows of matter and energy that constitute life at planetary scales. Metabology posits that life and its environment are not separate entities interacting across a void, but rather a unified, continuous flux. To understand habitability is to understand the governance of these flows across both space and time.

Spatially, planetary metabolism requires the establishment of boundaries and interfaces, what we might term Bhumic architecture. The soil beneath your feet, the ocean currents cycling nutrients across hemispheres, the atmosphere regulating heat and filtering radiation are all active, semi-permeable membranes regulating the exchange of carbon, nitrogen, water, and photons, the skin of the world, so to speak. They are the spatial manifestations of planetary metabolism.

Space is only half the equation. Drawing upon Bergson’s concept of durée - a continuous, indivisible flow of lived time - we recognize that a planet’s habitability cannot be measured in the discrete clock time of human observation, but in the deep time of planetary durée. A habitable planet is one that has mastered the temporal governance of its metabolic cycles, maintaining a precarious, wobbling homeostasis over millions and billions of years, despite shifting solar luminosities, asteroid impacts, and massive geological upheavals.

Therefore, habitability is fundamentally a question of governance, not in the narrow political sense of parliaments and treaties, but governance as the distributed, decentralized regulatory system by which a biosphere negotiates its own survival. It is the complex web of feedback loops managing the spatial distribution of resources and the temporal pacing of evolutionary adaptation. To ask if a planet is habitable is to ask a systemic question: does it possess the metabolic infrastructure to govern its own duration?

Where do we come into this picture as planetary stewards? Answer: through the conscious act of terraforming.

II. Terraforming as Philosophical Engineering

How, then, do we actually study something as vast, complex, and temporally extended as planetary habitability? Science has traditionally relied on observation and analysis - breaking systems down to understand their component parts. But in recent decades, a powerful new epistemological paradigm has emerged: the paradigm of synthesis. This approach is best captured by a principle often attributed to the physicist Richard Feynman, found written on his chalkboard at the time of his death: “What I cannot create, I do not understand.” Note - ironically, Feynman was an arch reductionist, claiming in his famous lectures on physics that the most important discovery of all time is “matter is made out of atoms,” but I digress....

This is the essence of philosophical engineering: the practice of constructing conceptual and material frameworks that reveal the deep structure of the phenomena they attempt to replicate. The synthetic method does not merely interpret the world; it builds versions of the world, and in building, discovers what observation alone could never see.

Artificial intelligence researchers took this seriously from the start. If you want to understand the mind, they reasoned, build one. Your theory of cognition can be tested in the most direct possible way: does a system built according to those principles actually think? By engineering a cognitive architecture from silicon - by testing the hypothesis of substrate independence - researchers isolate the functional logic of intelligence from its biological wetware. The early failures of classical AI - its inability to handle context, embodiment, or tacit knowledge - revealed that mind is not a disembodied symbol-manipulating system. The attempt to build a mind led to claims that the mind cannot be separated from its environment. Then again, maybe it can - the successes of Deep Learning is convincing many that all we need is massive amounts of data fed into a brain in a vat.

Synthetic biologists applied the exact same constructivist logic to life. If you understand how living systems work, you should be able to synthesize one. When researchers at the J. Craig Venter Institute created the first artificial bacterial cell in 2010, and later stripped it down to a minimal functional genome, they found that roughly a third of the essential genes required for life had entirely unknown functions. By stripping away evolutionary noise and building life from standardized parts, synthetic biology moved from describing biological phenomena to demonstrating the absolute algorithmic requirements for vitality. Don’t get me wrong - we are far from synthesizing life from scratch, but the attempt to do so opens up questions about possible life that are quite different from the study of life as it has evolved.

Now, extend this logic one step further. If artificial intelligence is the synthesis of the mind, and synthetic biology is the synthesis of the cell, then terraforming is the synthesis of the planet. Terraforming - the deliberate transformation of a planet’s surface, atmosphere, and climate to make it habitable - is the constructivist method applied to planetary habitability. It is the ultimate epistemological tool, a privileged way of understanding what makes a world livable.

Consider the (realizable?) thought experiment of terraforming Mars. Our best understanding as of today is that Mars is a dead rock - to terraform Mars would be a profound synthetic inquiry into the mechanics of genesis, and potentially a violently evil act - terraforming forces us to take ethics where it’s never gone before. By attempting to induce a planetary metabolism from a cold start, we are forced to define exactly what a Minimal Biosphere requires.

Imagine the proposed pathways: placing orbital mirrors to vaporize the Martian polar caps, releasing engineered greenhouse gases to thicken and warm the atmosphere, redirecting comets to deliver water ice, and introducing genetically modified cyanobacteria to the regolith to begin producing oxygen. What is philosophically revelatory about this exercise is not whether it is technically feasible with today’s rockets, but what it forces the intellect to confront. You immediately discover that you cannot do any one thing in isolation. Warming the atmosphere changes the barometric pressure, which alters the water cycle. Introducing water alters the chemical weathering of rocks, which changes atmospheric chemistry. Seeding with life changes the atmosphere, which in turn changes the selective evolutionary pressures on the life you just introduced.

Every intervention is entangled. The system responds to your engineering as a complex agent in its own right, not as a passive recipient of your blueprints. Every failure in this theoretical process - every toxic soil interaction, every atmospheric leak - teaches us a crucial lesson about the hidden regulatory mechanisms that make Earth work. Terraforming forces us to transition from descriptive Earth sciences to prescriptive planetary engineering.

Hypothesis: we will not truly understand the ‘mind of a planet’ (its self-regulating systems) until we attempt to engineer its body.

Through the rigorous crucible of attempting to make a dead world live, we learn that life is not just something that happens on a planet; life is something that happens to a planet.

III. The Autopoietic Earth: Billions of Years of Terraforming

Now let’s turn that thought experiment back toward Earth, because Earth itself has been through exactly this process of terraforming. Once we adopt this synthetic lens, once we recognize terraforming not as science fiction but as the active engineering of habitability, we see the history of our own world in an entirely new light. Earth was not born habitable for the life that exists today; Earth was terraformed by the life that exists today.

Is terraforming the missing link between human history and planetary history? Between the Globe and the Earth?

The early Earth, ~ 4.5 billion years ago was not the verdant blue marble we know. Its atmosphere was thick with carbon dioxide, methane, and nitrogen, with virtually no free oxygen. Its oceans were rich in dissolved iron, and its surface was bombarded by ultraviolet radiation that would destroy most modern organisms within minutes. By any contemporary standard, it was an alien, highly lethal world. And yet, in that hostile environment, life emerged- and then proceeded, over billions of years, to transform the planet into something hospitable for an entirely different class of organisms, including, eventually, ourselves.

The history of our planet is a history of relentless, autopoietic (self-creating) biological engineering. The most profound terraforming event in our solar system did not occur through human technology, but through the metabolic innovations of cyanobacteria during the Great Oxidation Event, approximately 2.4 billion years ago. These microscopic planetary engineers invented oxygenic photosynthesis, harnessing solar energy to crack water molecules and excrete oxygen as a toxic metabolic byproduct.

Over hundreds of millions of years, this oxygen accumulated. It first reacted with dissolved iron in the oceans, producing the banded iron formations that geologists now read as the signature of this biological revolution, and then built up in the atmosphere. In doing so, these microbes triggered a mass extinction of anaerobic life, plunged the planet into a deep freeze by stripping the atmosphere of heat-trapping methane, and fundamentally altered the chemical composition of the sky and the sea.

They completely rebuilt the planetary interface. Life has been continuously modifying Earth’s habitability since it first appeared. Plants and their fungal predecessors transformed rocky, barren landscapes into living soils, creating entirely new Bhumic substrates for terrestrial life. Forests evolved to alter precipitation patterns, generating their own rain and regulating regional climates. Marine organisms, living, dying, and sinking, drove carbon into deep-sea sediments, drawing down atmospheric carbon dioxide over geological time scales and creating the limestone cliffs of today.

James Lovelock and Lynn Margulis, in developing the Gaia hypothesis, were pointing at exactly this reality: the biosphere is not a passive inhabitant of Earth’s surface, merely adapted to whatever conditions happen to prevail. It is an active modifier of those conditions. The planet and its biosphere have been in a relationship of mutual terraforming from the beginning.

Understanding Earth’s history as a massive, ongoing terraforming project demystifies the concept. It reveals that planetary engineering is not an unnatural violation of a pristine natural order; rather, it is the defining characteristic of a living world. Habitability is a hard-won, metabolically expensive state of equilibrium that must be constantly maintained against the relentless forces of cosmic entropy. The cyanobacteria were planetary engineers. The forests are planetary engineers. The question, therefore, is not whether planetary engineering is permissible, but what kind of planetary engineering serves life.

1. How to Build a Habitable Planet - Charles Langmuir and Wally Broecker. A supplementary reading for Month Two on Time, a core reading this month.

2. A Foray into the Worlds of Animals and Humans with A Theory of Meaning - Jakob von Uexküll. One of my all time favorites. Ed Yong’s An Immense World is a contemporary, popular rendition of Uexkullian ideas.

3. A Pattern Language - Christopher Alexander. Another all time favorite. We will not be able to do ‘wise’ terraforming without incorporating Alexander’s ideas.

4. A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through? - Kelly and Zach Weinersmith. Popular account of the promises and perils of terraforming.

5. The Goldilocks Enigma - Paul Davies. Popular exposition of fine tuning and habitability. There’s also the OG book on the Anthropic Principle by Barrow and Tipler.

It goes without saying that we won’t be reading these books from cover to cover in one month.

The underlying ambition, even if it’s a bit much for any single person to comprehend: to understand habitability, we must simultaneously hold the macro-scale of planetary formation - how a dead rock becomes a vibrant, life-sustaining system, as Langmuir and Broecker detail - and the micro-scale of lived experience, except that it’s not just human lived experience! Von Uexküll’s concept of the Umwelt is crucial here; he argues that every organism inhabits a subjective, meaningful world. A habitable planet sustains myriads of intersecting, subjective worlds.

If life itself is the original, relentless planetary engineer, then our conscious efforts to shape our environment must align with its deep logic. Christopher Alexander’s pattern language offers a methodology for this alignment, demonstrating how the spaces we build can either nourish or deaden the metabolic order of the communities that inhabit them. Whether we are designing a sustainable neighborhood on Earth or settling Mars, as the Weinersmiths explore, we cannot simply export our current extractive paradigms to new environments. In doing so, we will fulfil the promise of planetary sapience: the conscious, deliberate maintenance of the metabolic processes that allow the Earth to remain our home.

"The planet is in the species of alterity, belonging to another system; and yet we inhabit it, on loan… If we imagine ourselves as planetary creatures rather than global entities, alterity remains underived from us; it is not our dialectical negation, it contains us as much as it flings us away."

— Gayatri Chakravorty Spivak, Death of a Discipline (2003), pp. 72–73

Spivak's move against sovereignty is the oldest and, in a sense, the cleanest: deny that anyone ever held title. We are tenants on the planet, not owners of it, and no lease was ever signed. It's an argument in the register of alterity — otherness that can't be assimilated, not even by the state.

The engineering question I keep returning to is narrower and more exposed: if nobody holds title, on what basis does a tenancy get renewed or revoked? "On loan" needs a lender, or at least something that functions like one. Metabolic Standing is my attempt at specifying what that would actually have to check.

"My sense is that politics — the question of 'what is to be done?' — is for humans alone… I don't see how the holobiont… can be made into a political subject in human terms."

— Dipesh Chakrabarty, "The Planet Is a Political Orphan," Noema, 3 February 2022

And, more starkly, from the book itself: "there is nothing in the history of the planet that can claim the status of a moral imperative" (The Climate of History in a Planetary Age, p. 24).

Chakrabarty gave planetary thought its best available term — habitability, not sustainability — and then, twice in print, declined to let it do any political work. His reasoning is careful: the planet is disclosed by science, not built by us, and politics has only ever been a human vocation. The reasoning holds exactly as long as habitability stays a condition — something found, not made. The moment it becomes a metabolic achievement, something a system does and can stop doing, his own wall has a door in it. That's my bet, anyway: the door was there the whole time.

"Only such a structure of deliberate multiscalar governance, one that eschews the fetishization of national sovereignty, can ensure the habitability necessary to enable multispecies (and thus ultimately human) flourishing."

— Jonathan S. Blake and Nils Gilman, Children of a Modest Star (2024), via their own Aeon summary, "Governing for the planet"

I keep coming back to this passage because it's the closest anyone gets without quite arriving. Habitability, here, is what governance should aim at — "our new lodestar," in their own words a few sentences later. A lodestar sits ahead of you; it doesn't sit underneath you. Sovereignty in their account keeps its old job, just aimed at a better target through "planetary subsidiarity." What's missing, I think, is the harder claim: that habitability isn't the destination governance travels toward, but the ground it was supposed to be standing on all along, and that a government maintaining it badly should lose standing over the maintaining, not just adopt a nicer goal.

"De facto, functional decision-making — you could call it sovereignty, although I don't think we even need this word — is built into technical systems in ways that are not available to legal manipulation… Traditional Schmittian concepts about 'the political' … no longer really explain much… Technology can even be defined as the automation of decision."

— Benjamin Bratton, interviewed in Palladium, 11 January 2021

Bratton isn't arguing that sovereignty should move. He's reporting that it already has — into the stack of software and infrastructure that actually decides who gets water pressure, credit, a visa, a search result, before any legislature is consulted. His displacement runs downward, into the machine. My bet runs the other way: outward, into the metabolic systems the machine depends on to keep running at all. Both readings agree on the diagnosis — the old seat is empty. We disagree hard about what's sitting in it now.
