Cosmic Melancholia: On Planetary Sadness and the Unhappy Consciousness

Still from Lars Von Trier, Melancholia, 2011.

I recently read two works that struck me as uttered from the ruins: Sad Planets by Dominic Pettman and Eugene Thacker, and The Highway of Despair: Critical Theory After Hegel by Robyn Marasco. Each bears the mark of a philosophy that persists not in triumph but in mourning, thinking through despair as its final, fragile gesture of care. The English word “despair” is derived from the Latin “desperare,” which means “to lose all hope” or “to be without hope.” At its core, the term conveys an existential condition marked by hopelessness and a profound disconnection from the world.

Far from simply analyzing despair as an abstract concept, both texts invite us to dwell within despair. They write from within despair’s gravity, attuned to its textures and tones, refusing the comfort of critical distance. In Sad Planets, this means exploring a melancholy that suffuses the entire cosmos; in The Highway of Despair, it becomes a passage through a philosophical terrain where despair is not an obstacle but a necessary companion on the path to understanding.  

Despite their different domains—one astral and environmental, the other political and theoretical—both works converge in treating despair not as a mere pathology or nihilistic dead end, but as an experience to be inhabited and listened to, for perhaps some faint resonance of hope lingers beneath the lament.  

In Sad Planets, Pettman and Thacker trace a melancholic attunement that seeps across planetary and cosmic registers. The sadness here is not individual but astral, not merely human but woven into the very dust of being. Their prose shimmers with a cold lyricism, as if mourning the loss of the very possibility of mourning. It is the sadness of the stars, of entropy, of a universe that no longer promises return. They ask whether “everyone is sad” (or everything is sad), not only in human hearts but in the world itself.1

The book unfolds as a series of meditations bridging our all-too-human melancholia with an impersonal cosmic sorrow. The authors traverse key negative affects tied to ecological and cosmic crises, e.g., climate change, mass extinction, environmental collapse, and the solitude of deep space. In posing questions about how we should feel regarding climate catastrophe, and whether the planet was ever truly ours to begin with, Sad Planets decenters the human perspective: “Our world, there for us to save, to mine, to design, to refashion in our own image.”2

Pettman and Thacker suggest that the eerie feeling of witnessing ecological collapse may signal that the earth was never simply a human possession, but rather a vast, indifferent realm in which our fate is revealed. They juxtapose astronomical fact (for example, noting the eventual disappearance of Saturn’s rings) with poetic insight and literary allusion, from Christiaan Huygens’s first look at Saturn in the seventeenth century to Lord Byron’s and W. E. B. Du Bois’s meditations on nature. This eclectic approach highlights a striking paradox of our age: “Never before have we known so much about the planet; never before have we felt so estranged from that same planet—to say nothing of the wider cosmos.”3

Indeed, the more we learn about earth’s fragility and the cold expanse of space, the more profound a malaise seems to settle in. The book’s tone is by turns wry and elegiac. Sad Planets catalogues the many moods of our ecological moment, from dread and anger to helplessness, yet it foregrounds melancholy as the leitmotif. The sadness here is not merely personal but planetary and beyond, an astral melancholy woven into the dust of being.

Pettman and Thacker depict a cosmos where even the earth’s once-bright blue luster is dimming as the oceans turn “too polluted to function,” and where the sky itself seems to echo with an entropic sorrow.4 It is a sadness of the stars and entropy. This mourning encompasses crumbling ice shelves and distant nebulae alike, a universal elegy for a universe that no longer promises any cyclical return.

Robyn Marasco’s The Highway of Despair, by contrast, begins with Hegel’s concept of despair and sets it walking through the debris of political modernity. The title comes from Hegel’s famous metaphor about “the way of despair” (der Weg der Verzweiflung) from The Phenomenology of Spirit: the “highway of despair” is the tortured path that consciousness travels on its way to freedom.5 For Hegel, the mind must experience despair (the collapse of its certainties) as a necessary ordeal before it can break through to higher truth.

Marasco builds on this idea and asks what it means for critical theory today. In her view, despair is the lingering “passionate side of the critical tradition,” a state that can reveal a “fugitive principle of freedom” and even “what fills the void left by abandoned hopes.”6 Rather than seeing despair as a failure or dead end, Marasco approaches it as a dynamic force that keeps the flame of critical thought alive when naive optimism has died out. Marasco develops this thesis by engaging an “eclectic cast of thinkers” who each grappled with Hegelian despair under twentieth-century conditions. The Highway of Despair follows Adorno, Bataille, and Fanon as they read, resist, and reconfigure Hegel’s legacy amid a world of horrors.

These thinkers faced what Marasco calls the twentieth-century “collapse of revolutionary projects.”7 In other words, the failure of hoped-for futures of justice and emancipation. Confronted with genocidal racism, world war, and colonial oppression, they saw rational progress and Enlightenment ideals brought to the brink of ruin. Yet crucially, Adorno, Bataille, and Fanon did not simply abandon hope or turn away from critique; instead, they revalued despair itself as a source of insight and resistance. Each, in his own way, recenters the role of passion and negativity in critique, refusing to accept facile resolutions of reason or faith.

Marasco traces how these left-Hegelian figures embrace a kind of extreme negativity, what Marx (echoing Hegel) called “the ruthless critique of everything existing,” as a means to confront a world that seems beyond redemption.8 In doing so, they transform despair from a merely private emotion into a critical stance. For Marasco, despair becomes a critical passion: not a paralysis, but a drive to keep thinking and acting when traditional hopes have faltered.

Indeed, despair is reframed as a form of engagement—a way to truthfully acknowledge the brokenness of the world and thereby resist it. This perspective runs against the grain of any theory that tries to deny or escape negativity. Marasco pointedly argues against trends in critical theory that seek an easy exit from despair, insisting that we must confront and work through despair rather than bypass it. In this way, the book shows how the “dialectical passion” of despair can energize praxis and sustain thought even when there appears to be no way out of contemporary horrors.9 In a stark world where rational hope for a better future recedes, Marasco maintains that staring into despair is not self-defeat, but rather the beginning of a new kind of hope.

Thus, what The Highway of Despair ultimately affirms is a paradoxical hope within despair: by fully inhabiting the feeling of no-way-out, we discover the glimmerings of a freedom against all odds, a hope against hope itself. Here, despair is not a static mood but a journey, a cruel but necessary passage through contradiction, suffering, and negation. She insists that despair, properly inhabited, might open a path toward freedom. Where Pettman and Thacker drift among collapsed constellations, Marasco walks the broken road of dialectics, guided by a flickering torch of critique.

Together, these books chart opposing yet intertwined cartographies of grief: one cosmic and entropic, the other political and dialectical. They offer no consolation, no program, no exit. Instead, they provide the difficult grace of naming what it means to remain with the ruin, to think from within the aftermath, to listen, still, for what might be stirring beneath the silence.

Both conjure, almost inadvertently, the specter of Hegel’s unhappy consciousness: that moment when the subject becomes aware of its alienation from the absolute, and thus from itself. A being divided, caught in a painful oscillation between finitude and the longing for transcendence. Sad Planets resonates with this division: its voice drifts across abandoned orbits and dying stars with the desolate clarity of the unhappy consciousness suspended in exile. Its authors’ thinker of choice is Nietzsche.

Unlike Hegel’s figure, this consciousness does not move. Rather than endure the dialectical labor of reconciliation, Pettman and Thacker embrace the abyss. They decline the Hegelian wager that sorrow may be transfigured through conceptual effort in favor of a Nietzschean fidelity to the tragic. In place of Spirit’s arduous ascent, we are given a planetary poetics of lucid resignation. The cosmos is not the stage of Spirit’s becoming, but the archive of its impossibility.

This refusal of sublation, of Aufhebung, is both the strength and the philosophical limit of Sad Planets. By resisting the imperative toward system and synthesis, the book preserves the dignity of grief in the face of planetary indifference. Yet it risks aestheticizing estrangement, rendering melancholy a mood rather than a movement. The planetary scale flattens contradiction into tone; the dialectic dissolves into ambience.

In a moment when even mourning is subject to commodification, Sad Planets offers a contemplative stillness. But it is a stillness severed from historical mediation. For Hegel, negation is not an end, but the very motor of Spirit’s realization. In Pettman and Thacker’s vision, negation becomes a condition, weightless, atmospheric, and unresolved. Beautiful, yes, but static. A sadness that neither revolts nor reconciles, only orbits.

By contrast, Marasco’s The Highway of Despair ventures along Hegel’s tortuous path with a different agenda. Marasco revives the Hegelian dialectic of negation, urging us not to abandon hope but to transform despair into political and theoretical vitality. This is the Hegelian unhappy consciousness in motion: suffering through contradiction, yet summoned toward resurgence.

Pettman and Thacker befriend the abyss; Marasco transforms it into a road. While Sad Planets offers us the dignity of unresolved mourning, it also pauses the dialectic, leaving sadness to orbit without thrust. The Highway of Despair sees despair as a necessary step on the path of critique, leveraging divergence to summon radical thought and possibility. The former luxuriates in mood, the latter enacts movement. Together, they frame our condition: where we reside, and how we might fail better.
