Computers tracking us, an ‘electronic collar’: Gilles Deleuze’s 1990 Postscript on the Societies of Control was eerily prescient

Our cultural touchstones series looks at influential works.

Gilles Deleuze was one of the most original and imaginative thinkers of postwar France. A lifelong teacher, he spent most of his career at the University of Paris VIII, influencing generations of students but largely shunning the mantle of public intellectual.

His complex, creative books mix philosophy, literature, film and politics – not to give clear answers, but to spark new ways of thinking.

Postscript on the Societies of Control, published 35 years ago in the countercultural L’Autre Journal is Deleuze at his most accessible and prophetic.

Written at a time when the Cold War was ending, computers were becoming more common, and the internet was beginning to connect institutions, the essay describes the emergence of a new kind of society – one not ruled by a single stern voice but by the soft hum of networks.

How societies work

Postscript was written as an update to the work of Deleuze’s contemporary Michel Foucault, who had died in 1984. Deleuze called it a “postscript” not just because of its brevity (it’s only around 2,300 words in English translation) but to highlight he wasn’t refuting Foucault, just building on his work.

From the 18th to early 20th centuries, Foucault had argued, Western societies were “disciplinary societies”. Schools, factories, prisons and hospitals – institutions with walls, schedules, routines and clear expectations – moulded behaviour. People were trained, observed, tested and corrected as they passed from one institution to the next.

But in the late 20th century, Deleuze saw something shifting. He thought the stodgy old disciplinary institutions were “in a generalized crisis” due to technological advances and a new form of capitalism that demanded more flexibility in workers and consumers.

New systems of management and technology were starting to reshape people without sending them through traditional institutions. Deleuze wrote presciently, for example, that “perpetual training tends to replace the school, and continuous control to replace the examination”.

In business, he saw a growing idea of “salary according to merit”, transforming work into “challenges, contests, and highly comic group sessions” – something much at odds with the old model of the standard wage and the assembly line. Traditional government institutions like hospitals and the classic factory were embracing the model of the corporation, driven always by a profit motive and the need for better human tools.

To Deleuze, all this meant people were becoming more “free-floating” – they could be still playing socially useful roles but were being gently steered into them. This greater freedom, however, required a new system to keep everyone in line. He called this “modulation” to underline its dynamic, enveloping nature.

Like nudging, but everywhere

Deleuze described modulation as “a self-deforming cast that will continuously change from one moment to the other”. He meant that people were beginning to live in an environment where everything shape-shifts to encourage or discourage us in the right direction without explicitly putting up walls.

A prime example of how modulation has since become commonplace is nudging – the use of psychological techniques, often subtle and data-driven, to shape people’s behaviour.

Nudging didn’t really exist in 1990, but governments and tech companies use nudges all the time now. We’re nudged to eat healthier, buy, save, recycle, donate. Web sites use “dark patterns” – tricky designs that steer (or nudge) us toward certain choices. Social media feeds use algorithms to exclude us if we say the wrong thing. In fact, entire teams of behavioural scientists operate behind the scenes to manipulate many aspects of our lives.

Nudges can be good and can save us from poor choices, but their newfound moral acceptability (sometimes called libertarian paternalism) is very much a clue that Deleuze’s control society has arrived.

Control in your pocket

Deleuze, who died in 1995, wrote Postscript before the advent of the smartphone, but he foresaw that an “electronic collar” would assume a central role in society. He envisaged a “computer that tracks each person’s position – licit or illicit – and effects a universal modulation.”

Smartphones more than fit the bill. In the old disciplinary ways, they track where we go, what we search for, what we buy, how many steps we take, even how well we sleep. But if we apply Deleuze’s ideas to these phones, detailed surveillance is no longer their most important function. Our phones present and curate options.

In effect, they shape how we see the world. When you scroll through news or social media, for instance, you’re reading about a version of the world built just for you, designed to keep you looking, clicking and reacting – and keep you very finely attuned to what is acceptable or dangerous behaviour.

In Deleuze’s terms, this is pure modulation: not a forceful “No” but a softly spoken, “How about this?” Your phone doesn’t lock you in – it draws you in. It shapes what you see, rewards your cooperation, ignores your silence, and always keeps score. And it does this 24/7. You might unlock it hundreds of times a day. And each time it’s updated to guide your next move more precisely.

At the same time our phones quietly turn us into a set of credentials useful for regulating physical access to workplaces, bank accounts, information: In the societies of control, writes Deleuze, “what is important is no longer either a signature or a number, but a code: the code is a password.”

Data points not people?

Deleuze warned that, in a control society: “Individuals have become ‘dividuals,’ and masses have become samples, data, markets, or ‘banks.’” A dividual to Deleuze is a person transformed into a set of data points and metrics.

You are your credit rating, your search history, your likes and clicks – a different dataset to every institution. Such fragments are used to make decisions about you until they effectively replace you. In fact, for Deleuze a dividual has internalised this treatment and thinks of themselves as a net worth, a mortgage size, a car value – psychological anchors for control.

He illustrates this point with healthcare, predicting a

new medicine ‘without doctor or patient’ that singles out potential sick people and subjects at risk, which in no way attests to individuation.

How many health decisions are now made for us collectively before we ever see a doctor? We should be grateful for advances in public health and epidemiology, but this has certainly impacted our individuality and how we are treated.

Hard to detect

An unsettling part of Deleuze’s perspective is that control doesn’t usually feel like control. It’s often dressed up as convenience, efficiency or progress. You set up internet-linked video cameras because then you can work from home. You agree to long terms and conditions because your banking app won’t work otherwise.

One problem is there are no longer clear barriers we can rail against. As Deleuze said:

In disciplinary societies one was always starting again (from school to the barracks, from the barracks to the factory), while in control societies one is never finished with anything.

Control doesn’t always crush – it can enable. Digital networks bring real freedom, economic possibility, even joy. We move more easily – both mentally and geographically – than ever before. But while we move, it always inside a kind of invisible map shaped by capitalism.

It’s no conspiracy because nobody has the whole map. So it’s difficult to work out exactly what action, if any, to take. As Deleuze concludes: “The coils of a serpent are even more complex than the burrows of a molehill.”

So what can we do?

Postscript doesn’t offer a political program beyond the sardonic comment that:

Many young people strangely boast of being ‘motivated’ […] It’s up to them to discover what they’re being made to serve.

There are ways to resist control. Some people demand more privacy or digital rights. Others opt out selectively – logging off, turning off, refusing to be nudged. Some look to art as a way of resisting its smooth grip. These acts – however small – may offer what Deleuze and his collaborator, the French psychiatrist and philosopher Félix Guattari, called lines of flight: creative ways to move not just against control, but beyond it.

The real message of Postscript, however, is its invitation to consider a timeless perspective. Any society must have a way to make people useful. So, what kind of society do we want? What kinds of restrictions are we willing to live under? And, crucial to this current age, how explicit should control be?

Coral reefs face an uncertain recovery from the 4th global mass bleaching event – can climate refuges help?

Tropical reefs might look like inanimate rock, but these colorful seascapes are built by tiny jellyfish-like animals called corals. While adult corals build solid structures that are firmly attached to the sea floor, baby corals are not confined to their reefs. They can drift with ocean currents over great distances to new locations that might give them a better chance of survival.

The underwater cities that corals construct are home to about a quarter of all known marine species. They are incredibly important for humans, too, contributing at least a trillion dollars per year in ecosystem services, such as protecting coastlines from wave damage and supporting fisheries and tourism.

Unfortunately, coral reefs are among the most vulnerable environments on the planet to climate change.

Since 2023, exceptionally warm ocean water has been fueling the planet’s fourth mass coral bleaching event on record, causing widespread mortality in corals around the world. This kind of harm is projected to worsen considerably over the coming decades as ocean temperatures rise.

I am a marine scientist in Hawaii. My colleagues and I are trying to understand how coral reefs might change in the future, and whether new coral reefs might form at higher latitudes as the tropics become too warm and temperate regions become more hospitable. The results lead us to both good and bad news.

Corals can grow in new areas, but will they thrive?

Baby corals can drift freely with ocean currents, potentially traveling hundreds of miles before settling in new locations. That allows the distribution of corals to shift over time.

Major ocean currents can carry baby corals to temperate seas. If new coral reefs form there as the waters warm, these areas might act as refuges for tropical corals, reducing the corals’ risk of extinction.

Scientists know from the fossil record that coral reef expansions have occurred before. However, a big question remains: Can corals migrate fast enough to keep pace with climate change caused by humans? We developed a cutting-edge simulation to find the answer.

Field and laboratory studies have measured how coral growth depends on temperature, acidity and light intensity. We combined this information with data on ocean currents to create a global simulation that represents how corals respond to a changing environment – including their ability to adapt through evolution and shift their ranges.

Then, we used future climate projections to predict how coral reefs may respond to climate change.

We found that it will take centuries for coral reefs to shift away from the tropics. This is far too slow for temperate seas to save tropical coral species – they are facing severe threats right now and in the coming decades.

How coral reefs form.

Underwater cities in motion?

Under countries’ current greenhouse gas emissions policies, our simulations suggest that coral reefs will decline globally by a further 70% this century as ocean temperatures continue to rise. As bad as that sounds, it’s actually slightly more optimistic than previous studies that predicted losses as high as 99%.

Our simulations suggest that coral populations could expand in a few locations this century, primarily southern Australia, but these expansions may only amount to around 6,000 acres (2,400 hectares). While that might sound a lot, we expect to lose around 10 million acres (4 million hectares) of coral over the same period.

In other words, we are unlikely to see significant new tropical-style coral reefs forming in temperate waters within our lifetimes, so most tropical corals will not find refuge in higher latitude seas.

Even though the suitable water temperatures for corals are forecast to expand poleward by about 25 miles (40 kilometers) per decade, corals would face other challenges in new environments.

Our research suggests that coral range expansion is mainly limited by slower coral growth at higher latitudes, not by dispersal. Away from the equator, light intensity falls and temperature becomes more variable, reducing growth, and therefore the rate of range expansion, for many coral species.

It is likely that new coral reefs will eventually form beyond their current range, as history shows, but our results suggest this may take centuries.

Some coral species are adapted to the more challenging environmental conditions at higher latitudes, and these corals are increasing in abundance, but they are much less diverse and structurally complex than their tropical counterparts.

Scientists have used human-assisted migration to try to restore damaged coral reefs by transplanting live corals. However, coral restoration is controversial, as it is expensive and cannot be scaled up globally. Since coral range expansion appears to be limited by challenging environmental conditions at higher latitudes rather than by dispersal, human-assisted migration is also unlikely to help them expand more quickly.

Importantly, these potential higher latitude refuges already have rich, distinct ecosystems. Establishing tropical corals within those ecosystems might disrupt existing species, so rapid expansions might not be a good thing in the first place.

No known alternative to cutting emissions

Despite enthusiasm for coral restoration, there is little evidence to suggest that methods like this can mitigate the global decline of coral reefs.

As our study shows, migration would take centuries, while the most severe climate change harm for corals will occur within decades, making it unlikely that subtropical and temperate seas can act as coral refuges.

What can help corals is reducing greenhouse gas emissions that are driving global warming. Our study suggests that reducing emissions at a faster pace, in accordance with the Paris climate agreement, could cut the coral loss by half compared with current policies. That could boost reef health for centuries to come.

This means that there is still hope for these irreplaceable coral ecosystems, but time is running out.

Brazil’s ‘bill of devastation’ pushes Amazon towards tipping point

Source: The Conversation – Global Perspectives – By Philip Fearnside, Biólogo e pesquisador titular (Departamento de Ecologia), Instituto Nacional de Pesquisas da Amazônia (INPA)

A bill essentially abolishing Brazil’s environmental licensing system is just days away from likely passage by the country’s National Congress. Despite the environmental discourse of President Luiz Inácio “Lula” da Silva, what is known as the “bill of devastation” (PL 2159/2021) apparently has his tacit approval. Even if Lula vetoes the bill, anti-environmental voting blocks in the National Congress have more than the 60% in each house needed to override a veto.

The “bill of devastation” has been promoted as relieving “low impact” projects of unnecessary bureaucracy, but it is very much more than this. First, it is for both “low” and “medium” impact projects, two categories that are vaguely defined, allowing projects with major impacts to be benefitted. The bill applies to licensing at both the state and federal levels, and at the state level there is expected to be a “race to the bottom” as states compete to attract investments by loosening environmental restrictions.

The “medium impact” category is a misnomer, as it includes most mining projects such as the mine tailings dams that broke in 2015 at Mariana and in 2019 at Brumadinho to create two of Brazil’s worst environmental disasters.

Under the bill, these “low” and “medium” impact projects would be licensed by what is known as “self-licensing,”. This eliminates the need for an environmental impact assessment, public hearings and specification of compensatory measures in the event of accidents or other impacts. Basically, this self-declared statement consists of checking a series of boxes on an online form.

Bypassing any public or committee debate, at the last minute before the Senate’s plenary vote the bill was modified with an amendment that increased its environmental impact even more. The amendment created a “Special Environmental License” that would allow any project considered to be “strategic” to have an accelerated approval process, regardless of the magnitude of its impacts.

The amendment is believed to be specifically intended to facilitate the controversial mouth-of-the-Amazon oil project, which has major potential impacts both from potentially uncontrollable oil spills and from its impact on climate change.

Brazil’s imminent climate disaster

Global climate and the Amazon forest are both approaching tipping points where the process of collapse escapes from human control. These imminent disasters are intertwined: if the Amazon forest were to collapse it would release more than enough greenhouse gases to push global temperatures beyond the point where human society loses the option to contain climate change by cutting emissions to zero, and if global temperatures rise uncontrollably, it would soon push the Amazon forest to collapse.

The Amazon forest is on the verge of tipping points in terms of temperature, the ongoing increase in dry season length, the percentage of forest cleared and a combination of various climatic and direct anthropogenic impacts.

The loss of the Amazon forest that would result from crossing any of these tipping points would, among other impacts, sacrifice the forest’s vital role in recycling water.

A volume of water greater than the Amazon River’s total flow is released as water vapor by the leaves of the trees, providing rainfall that not only maintains Amazon forest but also maintains agriculture and city water supplies in other parts of Brazil and in neighboring countries. The water vapor is transported by winds known as “flying rivers” to São Paulo, the World’s fourth largest city, which depends on this water supply.

Amazon destruction

Given these catastrophic prospects, Brazil’s government should be acting decisively to halt the country’s greenhouse gas emissions and to lead the World in combatting climate change. These necessities are interrelated, as effective leadership is done through example and Brazil cannot continue to merely exhort other countries to reduce their emissions when its domestic decisions are acting to increase global warming. This includes the “bill of devastation”.

Rapidly phasing out fossil fuel use is fundamental to containing global warming. The amount by which human society must reduce its emissions and the trajectory in time that this reduction must follow are determined by analysis of the best available data and climate models.

The “Global Stocktake” by the Climate Convention, released at COP-28 in 2023, showed that anthropogenic emissions must decline by 43% by 2030 compared to 2023, and by 84% by 2050 to stay within the limit currently agreed under the Paris Agreement of 1.5 ºC above the pre-industrial average global temperature.

This limit represents a tipping point both for the global climate system and for the Amazon forest. Above this point there is a sharp increase in the annual probability of uncontrollable feedbacks driving the system to a catastrophic shift or collapse.

The mouth-of-the-Amazon project is critical. A massive auction of drilling rights, both onshore and offshore, is scheduled for 17 June, including 47 blocks in the mouth of the Amazon River.

Environmental approval of the first “experimental” well (FZA-M-59) is viewed as the key to international oil companies being willing to bid on these blocks. The head of the Brazilian licensing agency (IBAMA) has been under intense pressure to approve the project.

Oil project

Within the licensing debate, the focus is almost entirely on whether Petrobras has the infrastructure and personnel to mount a rescue operation for marine wildlife in the event of an oil spill, rather than the more basic question of whether a leak could be plugged if it should occur.

Unfortunately, there are strong indications that a leak could not be plugged for months or years, as the site has double the 1.5-km water depth at the Deepwater Horizon well in the Gulf of Mexico that spilled uncontrollably for five months in 2010, and the ocean currents are much stronger and more complex in the mouth of the Amazon.

Petrobras constantly brags about its long experience with offshore oil extraction, but neither Petrobras nor any other company has plugged a leak at a location with the depth and complexity of the mouth-of-the-Amazon site.

Containing global warming is inconsistent with opening new oil fields due to the economic logic of these projects, which is different from the economics of continued extraction of existing oilfields. This is what led the International Energy Agency (IEA) to recommend that no new oil or gas fields be opened anywhere in the World.

In the case of the mouth of the Amazon project, the expectation is that it would take five years to begin commercial production and another five years to pay for the investment; since no one will want to stop with zero profit, the project implies extracting petroleum for many years after that – far beyond the time when the World must stop using oil as fuel.

Petrobras claims that the mouth-of-the-Amazon project and other planned new oilfields are needed for Brazil’s “energy security” to guarantee that Brazilians will not lack fuel for their vehicles.

The falsity of this argument is obvious from the fact that Brazil currently exports over half of the oil it extracts, and this percentage is expected to rise with the planned expansion. The reserves in Brazil’s existing oilfields are far greater than what the country can consume before fossil-fuel use must cease. In other words, the expansion of oil extraction is purely a matter of money.

Another argument promoted by Petrobras and by President Lula is that the oil revenue is needed to pay for Brazil’s energy transition. While the energy transition must indeed be paid for, it should have a guaranteed place in Brazil annual budget, like health and education, and not be treated as something optional that depends on windfall financial gains.

President Lula’s sleepwalk

President Lula apparently lacks understanding of Brazil’s suicidal course towards a climate catastrophe. He has surrounded himself with proponents of projects with enormous climatic consequences, such as his minister of transportation who presses for Highway BR-319 and his minister of mines and energy and the president of Petrobras who push for the mouth-of-the-Amazon and other new oil and gas projects.

Clearly, Lula does not listen to his minister of environment and climate change on these issues. He lives in a “disinformation space,” to use the term coined by Ukrainian President Volodymyr Zelinski to describe Donald Trump. The question of whether President Lula will awake from his sleepwalk before COP-30 in November is critical, as this is his opportunity to assume global leadership on climate change. Although there is no indication that this is likely, efforts to penetrate his disinformation space must continue.
