Review

Set in 2096, some fifteen years after the events of Blindsight (2006), Echopraxia presents a bleak vision of humanity on the verge of disintegration under the pressures of posthuman experimentation. The second novel in Peter Watts’s Blindsight series, it continues his multilayered investigation into the nature and evolutionary purpose of consciousness, extending the inquiry to the foundations of logical reasoning and rational thought.

The story follows Daniel Brüks, a retired biologist who has turned his back on society and withdrawn to the Oregon desert. There, he spends his days sampling local wildlife, hoping to discover an organism whose DNA has escaped contamination by ubiquitous biotechnology. A modern-day Luddite, Brüks has become increasingly obsolete in a world where even an academic appointment would require extensive neurological augmentation. His isolation is abruptly shattered when he becomes entangled in a violent confrontation involving his neighbours, the mysterious Bicameral Order, an escaped vampire and the authorities of the outside world. With little understanding of what has happened, he finds himself aboard the spaceship Crown of Thorns, bound for Icarus, the antimatter installation that powered the Theseus expedition in Blindsight. Strange signals have begun travelling along its antimatter beam, apparently connected to the extraterrestrial transmissions that prompted the earlier mission.

Where Blindsight confronted humanity with an intelligence of genuinely extraterrestrial origin, Echopraxia turns its attention towards the alien within humanity itself. Brüks’s fellow passengers have diverged so radically from the biological and cognitive baseline that he struggles even to understand their behaviour. Most enigmatic are the Bicamerals, who control the mission and constitute its largest, although largely segregated, contingent.

The Bicameral Order is a form of collective intelligence, the product of extraordinary neurological engineering. Through the manipulation of cellular processes and the creation of densely interconnected neural structures, the Bicamerals have amplified intuition and pattern recognition to levels beyond ordinary human comprehension. Their seemingly religious nature arises from the deliberate stimulation of neurological mechanisms associated with revelation and ecstasy. At their level of cognition, scientific discovery and religious inspiration become virtually indistinguishable.

Yet these extraordinary abilities come at a considerable cost. In everyday life, the Bicamerals are almost helpless, frequently requiring assistance with the simplest physical tasks. They depend on specially trained interpreters to translate their insights into concepts accessible to conventional scientists. Their internal modes of communication are so far removed from ordinary language that meaningful conversation with an unmodified human such as Brüks is effectively impossible.

The Bicamerals appear perpetually several steps ahead of everyone else, rendering any attempt to anticipate their motives futile. Brüks understands little of what unfolds around him and can only assume that his presence serves some hidden purpose. His principal points of contact are the ship’s heavily augmented humans, known as Trans, including the military officer Jim Moore, although even they struggle to comprehend the Bicamerals’ intentions.

Brüks’s intellectual inferiority is a source of considerable amusement among his fellow passengers, who nickname him ‘the roach’. They insist that the designation is not necessarily derogatory. In evolutionary terms, cockroaches are exceptionally successful organisms, their resilience tested across countless generations. Brüks may lack the extraordinary cognitive abilities of his companions, but his comparatively unmodified biology has been optimised through millions of years of natural selection. He is unlikely to suffer the specialised vulnerabilities that accompany more radical evolutionary departures.

Valerie, the genetically resurrected vampire, is incapacitated by particular configurations of intersecting lines, a neurological vulnerability underlying the traditional vampire’s fear of crucifixes. The Bicamerals, meanwhile, depend on elaborate technological interventions and continual refinements to sustain their extraordinary capabilities. Brüks, for all his limitations, remains a remarkably robust biological design.

As the journey progresses, several of the Trans begin confiding in him. Perhaps his relative simplicity makes him a safe repository for their anxieties. Equally, their growing attachment may reflect a residual nostalgia for the humanity they have progressively abandoned. Brüks becomes an unlikely witness to the psychological costs of posthuman evolution, surrounded by beings whose extraordinary abilities have left them increasingly estranged from ordinary human experience.

Although technological singularity is not explicitly foregrounded, Echopraxia depicts a civilisation approaching a profound evolutionary rupture. Earth is beset by environmental catastrophe, agricultural collapse and outbreaks of increasingly incomprehensible biological and technological phenomena. Human culture has become similarly transformed. Art, once a means of eliciting emotional responses through human creativity, has largely given way to technologies capable of generating experiences directly.

Machines increasingly perform the intellectual labour once considered humanity’s defining achievement. They formulate questions, design experiments and interpret their results. Human beings are no longer necessarily the principal agents of scientific discovery, but increasingly the subjects of processes they can neither direct nor fully comprehend.

Brüks characterises his era as a post-Anthropocene explosion, witnessing what may be the final dissolution of humanity as a coherent species. Whether the future belongs to autonomous machine intelligence, resurrected vampires or one of the proliferating posthuman lineages, including Bicamerals, membrains, multicores and Chinese Rooms, remains uncertain. What seems increasingly clear is that biological humanity has lost its privileged position in the evolutionary order.

In Blindsight, Watts explored the possibility that self-awareness is an evolutionary inefficiency, an expensive by-product of cognition that sufficiently advanced intelligence might eventually discard. Echopraxia extends this unsettling argument to rationality itself.

Rather than treating logical reasoning as an evolutionary adaptation for discovering objective truth, Watts entertains the possibility that rational thought developed primarily as an instrument for controlling the environment. Its usefulness may therefore be contingent rather than fundamental. Under sufficiently different evolutionary or technological conditions, other forms of cognition might prove vastly more effective.

The Bicamerals embody this possibility. Their discoveries arise through processes resembling revelation rather than deliberate reasoning, yet their results consistently surpass those produced by conventional scientific methods. Their achievements suggest that conscious, step-by-step rationality may be neither the highest nor the most efficient form of intelligence.

Indeed, the entire Bicameral project rests on the proposition that the human mind is burdened by evolutionary compromises, perceptual distortions and inherited cognitive limitations. To achieve something approaching genuine rationality, these deficiencies must first be dismantled. The mind must, paradoxically, be damaged before it can overcome the constraints of its own design.

Watts thus carries the implications of posthumanism beyond the familiar questions of bodily enhancement and technological transcendence. Where much science fiction imagines the future as an extension or amplification of human capabilities, Echopraxia questions whether the cognitive faculties we most closely associate with humanity have any enduring evolutionary value.

Brüks’s predicament crystallises the novel’s central paradox. Surrounded by beings whose intelligence exceeds his comprehension, he remains one of the few characters capable of recognising the existential significance of what is happening. His very limitations make him a witness to humanity’s possible extinction, even as they prevent him from fully understanding the forces bringing it about.

In Echopraxia, the future does not necessarily belong to beings who think more clearly, reason more logically or possess a deeper understanding of themselves. It may belong to forms of intelligence that have abandoned these familiar attributes altogether. The novel leaves open the deeply unsettling possibility that consciousness and rationality, far from representing the culmination of evolution, are merely temporary adaptations on the way to something radically different.
