Sad Planets

Rate this book
"Everything is sad," wrote the Ancient poets. But is this sadness merely a human experience, projected onto the world, or is there a gloom attributable to the world itself? Could the universe be forever weeping the "tears of things"?

In this series of meditations, Dominic Pettman and Eugene Thacker explore some of the key "negative affects"—both eternal and emergent—associated with climate change, environmental destruction, and cosmic solitude. In so doing they unearth something so obvious that it has gone largely the question of how we should feel about climate change. Between the information gathered by planetary sensors and the simple act of breathing the air, new unsettling moods are produced for which we currently lack an adequate language. Should we feel grief over the loss of our planet? Or is the strange feeling of witnessing mass extinction an indicator that the planet was never "ours" to begin with?

Spanning a wide range of topics—from the history of cosmology to the "existential threat" of climate change—this book is a reckoning with the limits of human existence and comprehension. As Pettman and Thacker observe, never before have we known so much about the planet and the cosmos, and yet never before have we felt so estranged from that same planet, to say nothing of the stars beyond.

Dominic Pettman and Eugene Thacker are both old friends of mine. I suppose this might have affected my response to their new book. But believe me, SAD PLANETS is both brilliant and original. It works through massive swathes of contemporary culture, and finds in it all massive reasons for us to be melancholy or depressed. In books, movies, and other recent cultural phenomena, SAD PLANETS finds evidence that our anthropocentric fantasies are deluded. Human beings aren't eternal, aren't brilliantly inventive, and aren't at the center of everything. Arguably, the world is telling us this all the time; but Pettman and Thacker show us that our own culture does it too, even in spite of ourselves. Our own efforts at reaching towards transcendence teach us the lesson that we cannot actually ever succeed at this. Our own forms of consolation and self-reassurance in fact end up letting us down and revealing the bleak hopelessness that we would do nearly anything to avoid recognizing. The book is fairly long, but it is intensely readable -- both in its welcoming and open style (unusual in books of High Theory, but very effectively managed here), and in its choice of innumerable examples, covering everything from Immanuel Kant to David Bowie, from European Renaissance humanism to postmodern fiction, and from bizarre apocalyptic cults to sober scientific studies. There is a certain sort of exhilaration that results from reading this book at length -- a sense that we cannot ever get enough, that there is always more for us to devour and to transform -- and yet this exhilaration is entirely in the service of the message that there is no hope, no exit, no transcendence, no departure from our terminally finite and miserable condition. It is almost as if we are being infinitely reminded that we can never attain infinity. The book exceeds all limits in its proclamation that there is no escaping our very narrow limits. This is an aesthetic accomplishment of the highest order, even as it conveys the message that aesthetic accomplishments count for little. The book goes along with a lot of other recent scholarship and creative activity that seeks to decenter human beings, to suggest that the world is not to our measure, and that there are whole ecologies for which we count for very little -- whether we are thinking of planets like K2-141b (where the oceans are made of lava on the light side, and vaporized rocks and magma shower down from the atmosphere on the dark side), or simply of the ways that trees and insects have their own sensibilities which need not have any regard for ours. But Sad Planets is also a book about affect, or feeling: its most powerful (and to me, surprising) aspect is how it suggests that our unavoidable and continuing reflection on the way that the world and the universe are not to our measure and do not care for us leads us predominantly to feelings of deep sadness (rather than, say, Nietzschean resolution to surpass it all, or -- my own inclination -- sheer gibbering terror). Sadness, or melancholy, is more than a momentary tonality; it is a whole kind of atmosphere of feeling within which we are bathed, and within which the distinctions between self and other, human and inhuman, and so on, tend to break down (but without ever vanishing entirely). There may not be any end of the world, in the sense that the ending of the world is a continual process that itself never entirely culminates; but the termination of things, in its very interminability, bathes us in tears and in grief. Here I am using perhaps an overly philosophical (or deconstructive) terminology in order to summarize something that Pettman and Thacker would never express in such a way -- because the intellectualized description of the situation is a way of failing to fully deal with it. And perhaps the real lesson of the book is that there is no way to ever fully deal with our overall reality. But by translating this dilemma from an intellectual one into an emotional one -- sadness as the best response we are capable of -- Sad Planets not only contributes powerfully to the project anthrodecentering, perhaps the most urgent intellectual task of the early 21st century, but also establishes itself alongside the greatest texts about melancholia in the English language: Robert Burton's Anatomy of Melancholy and Andrew Solomon's The Noonday Demon.

Wonderfully strange and eclectic, sometimes self indulgent: think A Thousand Plateaus crossed with an updated Annie Dillard, but about the ultimate sadness and loneliness of being alone and mortal in an apparently empty and lifeless universe.

Wandered a bit too far afield at times, but ultimately an affecting and timely book that tries to capture how it feels to live on a planet that we seem to be rendering ever more uninhabitable, and to contemplate our collective end.

Café para cafeteros e por cafeteros refírome a esa intersección de nerd que combina interese pola astrofísica, as novas ontoloxías do século XXI, a ecoloxía e todas as formas posibles de maxia e esoterismo, así como ter pasado por un episodio depresivo mínimo unha vez ao ano —é dicir, o mismísimo Víctor Soho—.

Resulta raro dicir que este libro de máis de 500 páxinas non se sente tanto un proxecto filosófico como unhas anotacións de colegas, formalizados como microensaios, sobre temas diversos, pero, mesmo con algún momento de absoluto cringe —como a cita a ese sketch bastante patético de Annie Hall— sinto que aquí hai un traballo estimulante e moi ben interrelacionado sobre as cuestións das que falaba previamente. Penso que é algo que lle acontece a Thacker en xeral, mesmo nos seus proxectos moi ambiciosos, que moitas veces resulta mellor arquivista e bibliógrafo —no sentido de que é capaz de presentar fontes moi diversas e puntos comúns moi únicos— do que é un analista preciso.

Sen dúbida, as súas lóxicas de pesimismo cósmico resultan anticuadas, moi da década pasada, así como a súa postura nihilista é demasiado naif e adolescente —aínda que penso que, no fondo, iso podes dicilo de calquera forma nihilismo—, pero en vez de usar iso na súa contra atopa nalgo tan esgotado e fácilmente simplifcable nunha colección absurda de lecturas e pensamentos creativos. Pode que o tema mereza un libro máis brillante, pero xa lle gustaría a meirande parte de temas ter autores tan propositivos e enciclopédicos como Thacker para pensalos.

❖ ❖ ❖

Whatever interesting and arresting insights the authors of Sad Planets produce, their unfocused political tail-chasing amounts to celebrating the status quo and extolling its recent figurehead, the notorious Jew-hater Greta Thunberg.

As a Marxist, I can only say I champion:

[….] More and more the future for humanity depends on working people taking power into our own hands, and establishing a workers and farmers government that will rule as stewards of nature and human life. Only the working class today is capable of taking advantage of scientific improvements and unleashing the capacities of human labor for the benefit of all. Workers need to strengthen our struggles today for jobs, better wages and conditions, for workers control of production and to safeguard the earth’s natural resources from the impact of burning fossil fuels.

There is no way to expand energy production, and to reduce the poisoning of the atmosphere from carbon emissions, without increasing the use of nuclear power. Worldwide, 450 nuclear reactors generate 10% of the total electricity consumed today, a drop of 15% from 2005. Beijing aims to surpass Washington as the largest generator of nuclear power in five years. 

Operating reactors to prevent nuclear meltdowns, constructing secure containment vessels and disposing of radioactive waste can and must be done safely — but only if workers and our unions fight to take control of production from the bosses on the road to taking political power.

A compelling, almost lyrical literature review of all things apocalyptic, post-capitalist, astrological, melancholic. Feels in conversation with recent releases on the philosophy of extinction and anti-natalism (i.e. Todd May, Ben Ware). Accessible, comprehensive, and consistently moving.

A series of essays. The sadness of humanity, the sadness of the universe. The inexplicable melancholy of 'countless celestial bodies...forever out of each, winking at one another across quantum ballrooms of unfathomable distances.'

To be the first dog cast out into space. The first monkey. The first rover. To be a defunct satellite, listlessly cast adrift in the infinite chasm of deep space. Deeply indifferent deep space. To be human.

The limits of human understanding. The feeling of: I'm learning more, and I'm understanding more, and in the end, I don't feel so different; in the end, it all feels the same - every direction leads to the same place, a gaping abyss of darkness, forever.

How does one mourn their own species' extinction? Without completely estranging yourself from the very species you belong to - how should one interpret this feeling? - that what they are witnessing is already dead, long gone, that the person they said hi to on their morning walk is now only a floating remnant, an empty face attached to a soon-extinct species? That the very trees, and their pleasurable shade, are merely artifacts of a lost planet? That one day everything will die - the humans, the trees, the bacteria floating in the oceans, the oceans - everything will go?

'Of course every human who ever lived finds themselves in the same boat, as it were, or on the same spaceship: embarking on a journey that cannot end well, in the sense that it will terminate in oblivion.'

I remember the disturbed feeling that came to me when a grade school science teacher explained to the class that yes, one day, not only will our planet die out, but so too will the sun, and eventually the galaxy, and eventually the universe. In fact, he said, the very stars you see in the night sky tonight may already be long dead. What you see may indeed be only the faint afterglow of a thing that once was.

I only got to about page 200 before putting it down indefinitely so I may not be the most reliable opinion on this one, but I will say I did enjoy what I did read. Part of the reason why I put it down was because I started getting fatigued by the very repetitive themes. It goes over the same 5 or so topics about the impact of the actions of our species and our place within the reality that we find ourselves in.

This is the first book I’ve picked up since high school and has been my introduction into philosophy in general and it did a good job of not seeming too esoteric in its presentation, and being very easily accessible with its concise essay format allowing more brief reading time.

I did want to move on to other books however, but what I did read was very insightful and granted me a better affective understanding of this world that I find myself in.

How can I explain my adoration for this book without also sounding entirely depressed? It perfectly encapsulates the current and pervasive mood that is being felt by humanity. The uncomfortable tickle in the back of our collective unconscious telling us that something isnt right. Its reassuring to have these feelings written out so well and with so many reference texts, movies, and art to discover. I think this one will stay one of those books I will forever recommend and that I will revisit year over year.

Wonderfully written Mr Pettman and Mr Thacker. Thank you for this.

Using the star system as follows: 0 = trash, I read it but I wish I hadn't, 1 = tolerable as a distraction but little more, 2 = an OK read, preferable to not reading but I'm not likely to recommend it, 3 = a good and enjoyable read, I'd recommend it to most, 4 = important, enhancing, and/ or a great read, I'd strongly recommend it and may read it again, 5 = transcendent, incomparable, and/ or life changing.

Be here now, be sad.

But even when we know that nothing leads anywhere, that the universe is only a by-product of
our gloom, why should we sacrifice this pleasure of tottering and of splitting our skulls against
heaven and earth? EMC

Sad planets posits itself as a series of meditations, chiefly intuiting the emotionality of the universe and exploring cosmic sadness. I found most of these ideas interesting but they soon and often become redundant, unnecessary, contrived and myopic. I was also saddened about the way the authors conceive of the climate crisis. So much of it was so needlessly doomful and hopeless. They seem weirdly insistent on framing humanity as a virus, the earth as its impersonal and disaffected host trying to get rid of us. This is often done as a way to try to illustrate the Modern Man™️ and his alienation from the natural world, which is valid, but it often steers into seeing all humans as inherently and irrevocably flawed, incompatible with the Earth, etc. I think they could’ve taken one step back and seen how faulty, single minded, obtuse, colonial, uncurious, damaging, arrogant and untrue a lot of their takes are in this area.

What I found most compelling were the moments when the authors tap into a deeper and more abstract mode of wondering. A lot of the mini essays have something to do with human emotion; They’ll look into some piece of writing, a movie, an author, a historical event, the future, political happenings, from this vantage point of affect and how it flows between the interior and the exterior of the human world. The book soon becomes a kaleidoscope of the human reckoning with his own existence, his consciousness, his doom, his love, his planet. In looking to the cosmos the authors kind of beautifully illuminate some important parts of being alive. At times it seems so enlightened.
