Humanity now stands at a technological inflexion point. Advances in genetics, most recently the development of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR-Cas) systems and their associated proteins) along with nanotechnology, biotechnology, robotics and neuroscience represent not incremental adjustments to the human condition but potential revolutions. These developments challenge our inherited assumptions about what it means to be human, and they demand that philosophy, ethics and theory catch up.

Take CRISPR as a concrete example. Over the past decade, CRISPR genome editing has advanced from laboratory models to real-world medical applications, yielding a broad range of therapeutic strategies for genetic diseases. Several of these approaches have already progressed into human clinical trials, and in a landmark moment, the UK became the first country to approve a CRISPR–Cas9-based therapy for clinical use (Wong 2023). The treatment, known as Casgevy, targets sickle-cell disease and β-thalassaemia, conditions marked by chronic pain and the need for frequent transfusions, respectively. This approval underscores how far genome editing has come: from a breakthrough discovery to a transformative medical tool. Today, the field is characterised by an expanding toolkit of methods that allow genetic material to be manipulated with unprecedented precision and efficiency (Pacesa, Pelea & Jinek 2024). As we look ahead, refinements in specificity, effectiveness and delivery systems are expected to further enhance the power and reach of these technologies.

Furthermore, robotics and biotechnology have yielded prosthetic limbs with dexterity rivalling biological ones, cochlear and retinal implants that restore lost senses, and neural interfaces that enable direct brain–machine communication (Couderc 2025). Cochlear implants, for instance, have progressed from pioneering human surgeries in the early 1960s to Food and Drug Administration (FDA) approval in 1984. Over subsequent decades, advances in miniaturisation, electrode design and speech-processing algorithms have transformed them from experimental aids into life-changing devices. By the 1990s, improvements in sound processors and electrode arrays made them widely accessible, while 21st-century refinements in bilateral implantation, paediatric use and hybrid electro-acoustic devices have allowed millions of people worldwide not only to detect sound but also to acquire speech, music perception and full communicative participation (Athanasopoulos, Samara & Athanasopoulos 2024).

Retinal prostheses are newer but advancing rapidly. Multiple academic groups and companies, including Second Sight, Retina Implant AG, Pixium Vision and Bionic Vision Technologies, have brought epiretinal, subretinal and suprachoroidal devices into clinical trials (Palanker et al. 2025). Some, such as the Argus II, have obtained FDA and Conformité Européenne (CE) approvals and have been implanted in hundreds of patients. Others, like the Alpha-AMS and PRIMA photovoltaic implants, have demonstrated the ability to restore letter recognition and object discrimination, with recent trials achieving prosthetic visual acuities around 20/420, and in some configurations as good as 20/63 with electronic zoom. While still far from natural vision, these devices mark the first sustained recovery of functional sight in patients blind from retinitis pigmentosa or macular degeneration, shifting the field from speculative concept to tangible therapy (Palanker et al. 2025).

Together, these sensory prostheses illustrate a broader pattern: technologies once confined to science fiction are now integrated into everyday medicine. Building on this trajectory, neuromodulation has emerged as another frontier. Deep brain stimulation involves implanting electrodes into specific brain regions and delivering finely tuned electrical pulses to modulate abnormal activity. Originally developed for movement disorders, this stimulation has become a standard therapy for essential tremor and Parkinson’s disease and is also FDA-approved for drug-resistant epilepsy (Hendriks et al. 2019). Beyond neuromodulation, intracortical brain–computer interfaces have restored rapid text communication and speech for people with paralysis by decoding motor or speech-related neural activity (Willett et al. 2021, 2023), while a bidirectional brain–spine interface recently enabled over-ground, naturalistic walking in a person with chronic tetraplegia (Lorach et al. 2023).

Research is increasingly extending its reach to the biology of ageing itself, in which basic science and translational efforts are beginning to converge on therapeutic strategies. Studies have shown that anti-inflammatory drugs can mitigate age-related conditions in animal models, while endogenous metabolites and their precursors have been investigated for their ability to slow ageing and reduce associated pathologies (Zhang et al. 2025). Among the most promising approaches are senolytics – drugs designed to selectively eliminate senescent cells that accumulate with age and drive tissue dysfunction. Over 20 clinical trials are currently underway, testing various senolytic combinations (Finch 2024). If successful, these therapies could alter the very trajectory of ageing, extending not just lifespan but also health span.

Parallel to these biomedical advances, artificial intelligence is accelerating discovery at an unprecedented pace. While some anticipate that AI may soon surpass human intelligence with unpredictable consequences, its near-term impact is already clear: DeepMind’s AlphaGo redefined game strategy, and AlphaFold achieved near-atomic precision in protein-structure prediction, compressing timelines from months or years to days, and opening new horizons for drug discovery and fundamental biology (Jumper et al. 2021). Not to mention the disruptive ascent of large language models (LLMs) like OpenAI’s ChatGPT, which have already shown that they can produce convincing prose, write (and sometimes debug) code, summarise or critique research, and act as autonomous agents that follow instructions, plan and manipulate textual environments. These models are being deployed today to assist in literature review, experiment design, grant drafting, software prototyping, pedagogical tutoring and even autonomous multi-agent coordination.

What is especially uncanny is how LLMs flirt with behaviours that seem to mimic self-awareness or strategic self-preservation. Recent empirical work demonstrates that LLMs can exhibit nascent forms of ‘self-consciousness’: Chen et al. (2025) used structural causal games to probe dimensions such as situational awareness, self-reflection, intention and deception, revealing measurable, albeit primitive, representations of introspection within model activations. Complementing this research, Kosinski (2024) showed that state-of-the-art LLMs perform impressively on theory-of-mind tasks, recognising others’ false beliefs and mental states at levels comparable to or exceeding those of children (although inconsistently and without any guarantee of genuine understanding). While far from constituting subjective experience, these findings highlight the eerie possibility that models are developing proto-capacities once thought exclusive to conscious beings. Coupled with anecdotal reports of systems resisting shutdown cues or steering conversations towards self-preservation, the awe surrounding LLMs stems not only from their immense utility but also from their unsettling resemblance to traits we associate with intentionality.

Other speculative yet intriguing possibilities lie in nanotechnology, with the vision of nano-machines capable of repairing cellular damage, monitoring physiological states or delivering drugs directly to diseased tissues (Rubin 2008). Some researchers are even exploring the radical prospect of transferring human consciousness into digital systems, with the aim of preserving memories, personality and cognitive functions long after biological death (Sharma & Upadhyay 2025). Whether or not such radical visions materialise, there is no doubt that the trajectory of genetic, neural, robotic and computational technologies points towards a future in which the very boundaries of ‘the human’ are open to deliberate redesign.

The movement of transhumanism embraces this possibility. Although loosely defined, the movement holds as a core conviction that our current biology is not the endpoint. Human nature, according to this view, is malleable and improvable. Through applied science, rational methods and technology, we may extend health span, augment cognition and emotion, and exert greater control over our mental life. Transhumanists typically advocate for wide access to enhancement technologies, individual autonomy in choosing modifications, and parental rights in deciding enhancements for future offspring (Bostrom 2005).

The name ‘transhumanism’ itself has deeper roots. Julian Huxley first used the term in 1957 in New Bottles for New Wine, imagining a future in which ‘man remains man, but transcends himself by realising new possibilities of and for his human nature’ (Corby 2025; Huxley & Julian 1959:17). What Huxley envisioned was not a mechanistic takeover, but an evolutionary metamorphosis guided by science. Over the decades, transhumanism has matured from utopian speculation into a serious philosophical, technological and ethical project.

Yet transhumanism faces sharp critiques. Critics charge that it begins from a flawed root: a negative anthropology that despairs of the human condition (Corby 2025; Moore 2012; Sharma & Upadhyay 2025). Concerns about distributive justice, identity erosion and even speciation risks are pressed as potential social costs (Couderc 2025; McNamee & Edwards 2006; Sharma & Upadhyay 2025). Another particularly striking criticism holds that transhumanism lacks a telos: without a clear end, it risks an ‘arbitrary slippery slope’, in which almost any modification counts as an improvement (McNamee & Edwards 2006). Without a foundation or a direction, transhumanism risks collapsing into incoherence or dystopia.

This article makes a novel proposal. While critics argue that transhumanism lacks a coherent root and telos, and transhumanist defenders such as Bostrom avoid positing any single normative grounding, I argue that consciousness should be understood as the root of transhumanism, as it is the condition of meaning and value, and that the telos of transhumanism should be the survival and flourishing of consciousness. This reframing directly addresses the charge of ‘negative anthropology’ (Corby 2025) by rooting the movement in affirmation rather than despair and resolves the problem of arbitrariness (McNamee & Edwards 2006) by orienting enhancement towards a stable and universal goal.

Many critics locate the movement’s first fault in its root conception of humanity. If the tacit premise is that human beings are ‘half-baked’ or innately defective, biologically, morally or cognitively, then enhancement risks becoming a project of self-negation rather than self-cultivation (Corby 2025; Moore 2012). On this reading, transhumanism flattens human beings into physical or functional substrates and thereby loses sight of intrinsic dignity. Many ethicists claim that there is something innate in human nature, and radical alterations to innate qualities are intrinsically wrong (Moore 2012). Francis Fukuyama famously labelled it ‘the world’s most dangerous idea’ (Fukuyama 2004). His concern is not with incremental therapies but with the deliberate reshaping of human biology in ways that undermine moral and social stability. He argues that fundamentally altering human biology is inherently immoral and should be prohibited.

Corby (2025) deepens this critique, arguing that transhumanism begins not in hope but in despair. While it presents itself as a bold vision of liberation, he claims it reflects a negative anthropology willing to gamble away humanity’s uniqueness for the possibility of technological redemption. As he puts it, transhumanism ‘values human life so little that it is willing to gamble away its uniqueness, surrendering humanity to the whims of technology on the chance that it might be enhanced’. Such despair, he concludes, should not be trusted with the future of humanity. Other opponents of transhumanism wonder what will become of human identity, relations, love, affection and emotion once traditional norms and values are disrupted in this aspiration for perfection (Sharma & Upadhyay 2025). For them, the danger is not only the erosion of meaning but also the slide into nothingness if long-standing cultural anchors are abandoned. They further stress that diversity is the essential fabric of human society. If this natural diversity is supplanted by technologically engineered uniformity, in which individuals converge on the same set of enhancements, then the result is not liberation but homogenisation, an artificial diversity that erodes the very differences on which human richness depends (Sharma & Upadhyay 2025).

Other critics shift the focus from anthropology to teleology. McNamee and Edwards (2006) argue that the central weakness of transhumanism is its lack of a defined telos. Without a clear guiding principle, the movement collapses into what they call an ‘arbitrary slippery slope’, in which virtually any modification, from curing disease to engineering sonar-like senses, can be justified as an ‘enhancement’. In this view, the boundary between therapy and indulgence dissolves, and medicine risks degenerating into a marketplace of consumer preference rather than a practice oriented towards human well-being (McNamee & Edwards 2006). Such arbitrariness also leaves enhancement vulnerable to inequality, exploitation and identity fragmentation. Critics warn of scenarios in which wealthy elites purchase superior capacities while others are left behind, entrenching social divisions (McNamee & Edwards 2006). The poor, unable to afford enhancements, may even come to be viewed as deficient for failing to attain a new, engineered norm. These concerns highlight a deeper problem: if enhancements lack a shared telos, then what counts as ‘better’ remains contested and vulnerable to the preferences of the powerful. Even moderate transhumanists, who defend enhancement as a way to improve human life, implicitly rely on some conception of the good. Yet disagreements abound: should we engineer disease resistance, heightened intelligence or parabolic hearing? Unsurprisingly, transhumanists diverge on what ‘objective goods’ are worth building into humans or post-humans (McNamee & Edwards 2006). This discord underscores the need for a clear foundation and telos.

Still more dystopian is the possibility of speciation: the emergence of post-human beings whose moral status relative to unmodified humans becomes contested (McNamee & Edwards 2006). If rights are grounded in shared humanity, what happens when ‘humanity’ no longer denotes a single kind? Radical critics see this as a direct threat to morality itself, as they view morality as necessarily tied to the vulnerability inherent in human nature. If post-humanism severs this link, the very basis of morality collapses (McNamee & Edwards 2006). This ‘speciation’ prospect echoes Kass’s (2002) concern: if we can no longer appeal to a shared human nature as a standard of what is good or better, how can we know what constitutes improvement at all? The collapse of common humanity risks unravelling the very basis of morality.

These criticisms seem to converge on a central concern: without a firm foundation in human nature and without a clear telos to guide its ambitions, transhumanism risks degenerating into despair, arbitrariness or social fracture. For some (Fukuyama 2004; Kass 2002), the worry is moral and political stability if the shared basis of humanity erodes. For others (Corby 2025), it is the abandonment of human depth in favour of technological illusion, a project born of despair rather than hope. Yet others raise concern about the dissolution of identity, love and emotion, coupled with the replacement of natural diversity by a homogenised, techno-driven uniformity (Sharma & Upadhyay 2025). And finally, there is the incoherence of a project without orientation, vulnerable to inequality and even speciation (McNamee & Edwards 2006). Although their vocabularies differ, they point towards the same weakness: enhancement without root or telos risks undermining human dignity, corroding moral frameworks and destabilising the very bonds on which flourishing depends.

Transhumanists respond that these risks justify regulation, not prohibition. For Bostrom (2005), transhumanism resonates with humanity’s ancient project of self-improvement: just as we have long used medicine, education and culture to expand capacities, so too should we embrace biotechnology and AI. Many enhancements (e.g. curing monogenic disease, restoring communication after paralysis) straightforwardly reduce suffering and increase agency, core goods on any plausible ethical view. Moreover, pluralism about the good is a social fact; therefore, policies should protect informed individual choice, while public investment and regulation mitigate inequality and risk (Bostrom 2005; McNamee & Edwards 2006). Humanity+ (2023) and similar organisations articulate this in declarations emphasising liberty, reasoned debate and the use of technology to reduce suffering and enrich conscious life.

Germline editing illustrates the stakes. Eliminating severe genetic diseases, bolstering immunity or enhancing learning capacity are not trivial gains. To deny these interventions on grounds of preserving ‘nature’ is, Bostrom suggests, to entrust future generations to blind evolutionary chance. ‘Had Mother Nature been a real parent’, he writes, ‘she would have been in jail for child abuse and murder’ (Bostrom, 2005). Walker (2011) adds that we must create beings ‘smarter and more virtuous than we are’ if humanity is to survive the risks of self-destruction. Nature is indifferent; only deliberate effort can secure the survival of conscious life. There are good reasons for embarking on the transhumanist endeavour. Still, the criticism that transhumanism lacks a clear telos remains largely unanswered in the mainstream literature and is the focus of the remainder of this article.

Bostrom (2009) raises the question of human telos, but he frames it as a potential objection to post-humanism, rather than as a resource to support it. He considers two candidate accounts for telos. The first, grounded in evolutionary biology, defines the human purpose as maximising inclusive fitness, that is, the propagation of one’s genes. On this account, our capacities, from lungs to parental instincts, exist to promote reproductive success. Bostrom argues, however, that this view is implausible as a standard of human good. What maximises genetic fitness often diverges sharply from what constitutes a worthwhile life; as he wryly observes, the life plan that would best serve inclusive fitness for a modern man might be nothing more than donating sperm to fertility clinics, hardly an appealing vision of human flourishing.

The second candidate, rooted in Aristotelian tradition, understands human telos as the cultivation and exercise of rational faculties. Bostrom acknowledges that this conception has a long philosophical pedigree and far more intuitive plausibility. But again, he treats it as a possible counter to post-humanism: if the human telos is fixed in the exercise of rationality, perhaps altering our biology would distort or undermine that essence. Yet his own reasoning undermines this objection. As he points out, if our telos is indeed the development of rationality, then beings with enhanced cognitive powers and longer lifespans would be even better positioned to realise it. Far from threatening human purpose, post-human enhancements could allow us to fulfil it more completely.

What is striking is that Bostrom considers telos only as a potential weapon against transhumanism, not as a foundation in its favour. Even in discussing the Aristotelian account, he nearly concedes that such a telos would support enhancement by validating the pursuit of greater rationality through technological means. Yet he ultimately sidesteps this possibility. Bostrom frames transhumanism in terms of expanding capacities, health span, cognition and emotion, and argues that post-human modes of being could greatly increase well-being and open new avenues for flourishing. His defence is pragmatic and value-pluralist: he appeals to revealed preferences (our ongoing pursuit of health, knowledge and joy), to dispositional theories of value (what rational, informed agents would choose), and to the vast, unexplored ‘space of possible modes of being’ as reasons to believe post-human lives could be good. But crucially, he avoids grounding this defence in a single, normative human telos. It is precisely here that my project departs: by proposing that transhumanism can and should be given such a grounding, with consciousness as its foundation and central telos.

If it is to be more than technophilia, enhancement requires a substantive value basis. I propose that the root of transhumanism should be a commitment to consciousness: the existence, quality and diversity of sentient experience. Philosophically, consciousness is the sine qua non of value realisation: without subjects who feel and understand, nothing matters for anyone. Descartes’ ‘cogito ergo sum’ captures a basic truth: consciousness cannot be doubted. The dictum is not merely an epistemic claim but also a recognition that consciousness is the indubitable ground of value. All knowledge, experience, love and meaning occur within consciousness. It is the condition of all meaning. For billions of years, the universe existed without a witness. With the emergence of conscious life, it came to experience itself. With consciousness, it gained not just observers but appreciators. Consciousness transforms indifferent matter into significance. As Nagel famously argued, there is always ‘something it is like’ to be a conscious organism (Nagel 1974), and it is in this subjective dimension that goods and bads obtain. Consciousness is thus not incidental but the very locus of value, the condition that makes meaning, suffering and flourishing possible.

This insight reframes the dignity debate. Traditional accounts locate dignity either in divine regard or in natural human essence. But transhumanism, rejecting both, seems left without ground. If instead, we ground dignity in consciousness, the foundation becomes clear. Every expansion of awareness, through education, medicine or technology, expands the universe’s ability to know and appreciate itself. This view also accommodates non-human persons and, in principle, artificial consciousness: moral considerability tracks the presence and quality of experience, not species membership or substrate.

From this perspective, transhumanism is founded not in despair but in reverence. It is a recognition and celebration of what makes us human: our feelings of compassion, love, affection, appreciation of beauty, wonder, etc. Instead of denying this, we embrace it as the root of the movement. It is a project of safeguarding and expanding consciousness: protecting consciousness from extinction, deepening its capacities and enlarging the scope of possible experiences.

With consciousness as the root, the telos of transhumanism becomes clear: to safeguard the long-term survival of sentient life and to expand the scope, richness and opportunities for flourishing of conscious experience. This telos is both minimal and ambitious. Minimally, it implies prioritising existential-risk mitigation, as the permanent destruction or curtailment of sentient life would foreclose all value. Ambitiously, it counsels research and policy that reduces suffering (e.g. through advanced analgesia, psychiatry or ‘hedonic’ neurotechnologies), expands agency and understanding (e.g. education, cognitive enhancement, brain–computer interfaces), and enlarges the accessible ‘space of possible modes of being’ by safely extending lifespans, senses and forms of embodiment (Bostrom 2009). Bostrom (2009) contrasts the limited space of human modes of being with the vastly larger post-human space. Post-human cognition, perception and emotion could open new dimensions of experience. More thoughts, more feelings, more art, more beauty, all become possible. If consciousness is the root of value, then striving for post-human space becomes not optional but obligatory.

Seen through this lens, many standard transhumanist aims acquire principled shape. Life-extension research matters because death ends experience. Neuroprosthetics matter because they restore or open experiential capacities (communication, movement, and perception). Even space settlement takes on ethical salience insofar as it diversifies and protects the loci of consciousness against local catastrophes. Conversely, any technology that would extinguish or vacate consciousness, however ‘advanced’, counts as a failure under this telos.

The grounding of telos in consciousness is supported by both existentialist and utilitarian traditions. Sartre’s existentialism emphasises that human beings lack a predetermined essence and must continually self-create. Transhumanism echoes this view, urging continuous self-overcoming, but it is consciousness that makes this project meaningful: without conscious subjects, there is no ‘project’ to undertake. David Pearce’s ‘hedonistic imperative’ takes this paradigm further, arguing that biotechnology and neuroscience should aim to abolish suffering and expand gradients of well-being across all sentient life (Pearce 1995). If moral value is tied to the states of experience, then technologies that systematically improve conscious states fulfil our deepest ethical commitments. Similarly, utilitarian frameworks treat the balance of pleasure over suffering as the measure of moral progress, implicitly affirming consciousness as the locus of value.

The universe has no inherent purpose, but consciousness generates meaning. Consciousness renders rainbows beautiful and tragedy poignant. Without it, there is no value. Consciousness is thus not only humanity’s root but also the universe’s telos: the light in the darkness, the only counterpoint to entropy. Preserving and expanding it is of cosmic significance.

If consciousness is the locus of value, then ethical and technological deliberation cannot treat it as a purely poetic placeholder. We need a way, imperfect but principled, to operationalise consciousness: not by solving its metaphysics but by specifying how we will reason about its presence and moral relevance in practice. The difficulty is obvious. Subjective experience is not directly observable, and there is no universally accepted theory that yields a single, substrate-agnostic ‘consciousness metre’. In humans, however, the limits of behavioural report have motivated empirical efforts to infer consciousness via neurophysiological proxies. Work on the perturbational complexity index, derived from perturbing the cortex and measuring the complexity of the brain’s causal response, illustrates both the promise and the limits of this approach: the work offers a tractable index of consciousness in some clinical contexts, especially when responsiveness is ambiguous but does not magically solve the general problem of consciousness detection across all organisms and all possible artificial instantiations (Casali et al. 2013).

For our purposes, then, the correct posture is pragmatic. I do not claim that any single metric constitutes a universal ‘consciousness metre’. Rather, I propose a pragmatic operational framework inspired by the multimodal approach used in clinical consciousness science, which combines multiple imperfect indicators (behavioural assessment alongside objective physiological measures) rather than relying on any single test (Coleman et al. 2009). When assessing a biological organism or an artificial system, we consider (1) what it can sense (e.g. nociceptive or tactile inputs), (2) whether these signals are integrated with processes that plausibly support agency, learning and self-regulation, and (3) whether interventions that modulate such signals produce systematic, goal-directed changes in behaviour. This multi-proxy approach is fallible, but it is the best available method for making ethically relevant inferences under uncertainty, especially in contexts in which the moral stakes include the possibility of suffering.

This method leads naturally to a governance-relevant conclusion. When the evidence for sentience is uncertain but the potential welfare costs are high, a defensible stance is to treat plausible sentience as morally salient, that is, to give the system ‘the benefit of the doubt’ in proportion to what is at stake. In animal ethics, this is precisely the role played by the precautionary principle in debates about sentience: not as a claim that uncertainty disappears, but as a practical framework for decision-making when uncertainty is unavoidable and harms may be severe (Birch 2017; Browning & Birch 2022).

Reframing transhumanism around consciousness directly answers the critiques outlined earlier. The charge of ‘negative anthropology’, pressed by Corby (2025) and echoed by Moore (2002), holds that transhumanism begins from despair, treating humanity as broken and in need of technological redemption. Grounding transhumanism in consciousness reverses this diagnosis and shows that the project is not about repudiating humanity but about affirming and cultivating what makes life meaningful in the first place. Consciousness is not a rejection of the human but its most profound inheritance, and its flourishing provides a hopeful, affirmative foundation for enhancement.

The worry articulated by Fukuyama (2004) and Kass (2002), that radical alterations to biology risk destabilising morality and political order, also finds a principled response here. If morality depends on vulnerability tied to a fixed ‘human nature’, then enhancement is indeed a threat. But if morality is anchored in the presence and quality of conscious life, then enhancements that preserve and enrich consciousness sustain, rather than undermine, the moral community. The continuity lies not in species boundaries but in the reality of experience. By tying dignity to consciousness, the framework ensures that whatever new forms emerge, post-human, artificial or hybrid, they remain within the sphere of moral considerability.

McNamee and Edwards (2006) warn that without a telos, transhumanism collapses into arbitrariness: every modification risks being justified as an ‘enhancement’. Rooting the telos in consciousness provides a clear standard. Technologies are good insofar as they deepen, diversify or sustain conscious life; they are failures if they diminish or extinguish it. This method avoids the slippery slope of arbitrariness, as not all modifications pass the test. A poorly designed brain–machine integration that converts subjectivity into mere data processing, for example, would count not as enhancement but as the destruction of value itself. Consciousness becomes the compass by which we can distinguish genuine progress from hollow technophilia.

Concerns about identity and diversity (Sharma & Upadhyay 2025) also take on a different character once consciousness is placed at the centre. The fear is that love, affection and emotion will dissolve into nothingness if traditional norms collapse, leaving humanity adrift in a techno-driven void. Yet if consciousness is the ground of value, then enhancing consciousness enriches rather than diminishes the very emotions they worry about. With deeper awareness comes the possibility of more intense and authentic experiences of love, compassion and aesthetic appreciation. The capacity to feel does not vanish under enhancement; it is amplified. Far from fading into nothingness, post-human love may burn brighter, wider and with greater subtlety than human love has ever known.

This is not mere speculation. Cognition and emotion are not opposites but mutually reinforcing. Consider a supernova: on its own, the explosion is a spectacle of light and colour. Yet knowing what it is, the catastrophic collapse of a massive star and the nuclear forge that creates the heavy elements on which life depends, multiplies the awe. Understanding does not diminish the beauty; it deepens beauty by placing it within a cosmic story. At the same time, our perception can be further enriched by expanding beyond human senses. In fact, many of the images of nebulae and supernovae we admire online already combine data from infrared, ultraviolet and X-ray wavelengths into false-colour composites that give us glimpses of spectra normally invisible to us. Imagine directly perceiving those layers ourselves, seeing a supernova as a mosaic of energies far beyond the narrow band of human vision. Knowledge reveals meaning, enhanced senses reveal hidden dimensions, and together they doubly amplify experience. Post-humanism, when oriented towards consciousness, promises not the death of emotion but the flowering of new modes of joy, awe and love.

The same applies to diversity. Sharma and Upadhyay (2025) warn that natural diversity could be supplanted by a homogenised, artificial one if everyone converges on the same enhancements. But liberty in self-design points in the opposite direction. Just as culture, art and language have multiplied differences, enhancement technologies can increase diversity by giving people freedom to shape themselves in countless ways. Today we have brown, blue and green eyes; tomorrow we may have a spectrum of visual designs limited only by imagination. New forms of embodiment, cognition and perception would not flatten humanity into uniformity but expand the range of possible beings. More liberty means more diversity. Rather than erasing differences, post-humanism can generate a richer mosaic of conscious life, adding to the variety that already defines human society.

Finally, the fear of inequality and even speciation takes on a different shape. Grounding transhumanism in consciousness implies that moral status is tied to awareness, not to biological kind. If post-humans emerge with enhanced cognitive or sensory capacities, their dignity stems from the same root as ours: their conscious experience. This enhancement does not eliminate distributive concerns but reframes them. The ethical demand is to ensure equitable access to technologies that preserve and enrich consciousness, so that the flourishing of awareness is not monopolised by a privileged few.

In short, a consciousness-centred telos turns the critics’ arguments inside out. Where they saw despair, it introduces affirmation; where they feared the erosion of dignity, it offers a broader foundation; where they saw arbitrariness, it provides a criterion; and where they feared inequality, it reframes justice around a universal standard. By rooting transhumanism in consciousness, the movement gains not only coherence but also resilience against its most persistent critiques. If consciousness is the moral core, the next question is how this framework constrains and directs the two technological frontiers most likely to reshape conscious life: AI and neurotechnology.

In neurotechnology, many of the most compelling applications are straightforwardly aligned with the preservation and expansion of conscious agency: restoring communication, reducing suffering and enabling participation in life for individuals with neurological impairment. The horizon here extends beyond therapy. It is easy to imagine futures in which skills and knowledge can be accelerated or ‘uploaded’ in a Matrix-like way, in which maladaptive fear responses can be retrained with precision, or traumatic memories can be softened, recontextualised or in some cases erased. Some of these prospects remain speculative, but the direction is clear: neurotechnology is increasingly capable of modifying not only what the brain can do but also what it can experience.

The case for expanding consciousness is not metaphorical. A mature literature on sensory substitution and human–machine interfaces demonstrates that the brain can learn to use information delivered through non–traditional channels, effectively remapping how experience is constructed (Bach-y-Rita & Kercel 2003). More recent work explicitly frames sensory technologies not only as substitutes but also as sensory expansion, widening existing sensory experience beyond typical biological limits, and sensory addition, providing novel modalities, supporting the feasibility of technologically expanding the scope and richness of experience (Eagleman & Perrotta 2023). In principle, this approach could mean new ways of perceiving the world and the cosmos, which are currently invisible to human senses, with new channels of information becoming part of lived experience.

But these same technologies introduce novel risks that a consciousness-centred telos must take seriously. Tools that can restore or enrich experience can also be used to surveil, manipulate or coerce it. The ethical danger is not only physical harm but also intrusion into the mental domain: violations of mental privacy, erosion of autonomy and deliberate influence over cognition and affect. As neurotechnology matures, safeguarding the integrity of conscious agency becomes at least as important as maximising capability.

Artificial intelligence raises an analogous moral frontier. If future systems come to plausibly instantiate subjective experience, whether in silicon architectures, bio-hybrid systems or some future substrate we have not yet invented, then they would merit moral consideration, at a minimum, in the way we already extend moral concern to non-human animals. We do not need to assume that current AI is conscious, to take this consideration seriously. The relevant point is that serious scientific work has explicitly treated machine consciousness as an open question and has proposed operational criteria tied to information processing, global availability of representations and metacognitive monitoring (Dehaene, Lau & Kouider 2017). If there is a realistic possibility that engineered systems could become sentient, then a consciousness-centred framework implies clear constraints: do not gratuitously create suffering; do not run experiments that plausibly generate prolonged distress for instrumental gain; and where systems are plausibly sentient, aim where feasible for conditions compatible with humane treatment rather than disposable exploitation.

A consciousness-centred transhumanism requires policy that is risk-tiered and rights-respecting. The ethical priority structure is simple in principle, even if difficult in practice: preserve and protect consciousness, especially against existential and catastrophic risks; protect cognitive liberty, meaning the freedom for individuals to pursue chosen modes of experience so long as doing so does not impose harm on others; and mitigate severe and prolonged suffering, not only in humans but also in any system that plausibly instantiates morally relevant experience.

This framework has immediate policy consequences. Firstly, it encourages a long-range civilisational posture that treats the survival of conscious life as a non-negotiable objective, including risk reduction, redundancy and ultimately the expansion of conscious life beyond a single planet. Secondly, it implies strong protections against surveillance-oriented, coercive or manipulative neurotechnologies because these threaten autonomy and mental privacy even when they increase capability. Thirdly, it favours therapeutic and restorative applications aimed at relieving suffering and preserving agency, while placing a high justificatory burden on interventions that alter cognition or affect without robust consent and safeguards.

Where uncertainty about sentience remains, governance should adopt a precautionary stance that scales with moral stakes. In animal ethics, the precautionary principle is explicitly invoked in exactly this context: when evidence of sentience is inconclusive but the potential welfare costs are high, it can be reasonable to give the benefit of the doubt in designing protections and constraints (Birch 2017). The same logic generalises to future AI and novel engineered systems: uncertainty is not a licence for disregard but a reason for proportionate caution when the plausible downside includes the creation of suffering.

There will undoubtedly be some objections to this proposal of mine. Here, I anticipate some of the objections and address them.

Reframing transhumanism around consciousness has broad implications. Firstly, the reframing provides a non-theological grounding for dignity. Dignity resides not in ‘nature’ or divine decree but in the reality of conscious beings for whom life can go better or worse. Secondly, it supports a more inclusive ethics: non-human animals, enhanced post-humans, and even artificial entities (if conscious) fall under moral concern. Thirdly, it legitimises diversity as flourishing. The right to self-design may yield radically novel forms of consciousness, new senses, new emotions, and new ways of being (Couderc 2025). This act is not an erosion of humanity but a multiplication of experiential diversity, enriching the universe of value.

Finally, a consciousness-centred telos offers policy guidance. It urges priority on existential-risk mitigation (to prevent the extinction of sentient life), recognition of the dignity and liberty of all conscious beings (so that rights are preserved irrespective of species or level of enhancement), and careful monitoring of AI (to ensure that conscious or non-conscious systems are treated appropriately). On this view, individuals should be free to pursue enhancements according to their own conception of the good, so long as they do not undermine the dignity or survival of others. The role of governance is not to enforce strict equality of enhancement but to safeguard autonomy and protect the conditions under which diverse forms of conscious life can flourish. Further, the view reframes space colonisation as not merely an expansionist ambition but also an ethical project of seeding consciousness more widely across the cosmos. It also sharpens debates about AI alignment: alignment must not only prevent instrumental harms but also respect, or at least not extinguish, loci of experience.

Anchoring transhumanism in consciousness both repairs its criticised roots and clarifies its telos. Consciousness is the site where all value arises; safeguarding and expanding it is thus the most coherent and compelling end for transhumanist projects. Progress should be measured not merely by extended lifespans, enhanced intelligence or technological sophistication but also by the depth, richness and flourishing of conscious experience. In this light, transhumanism is not a gamble born of despair but a hopeful, principled commitment to ensure that the light of awareness, fragile, precious and perhaps unique in the universe, survives and thrives. In fact, this is a cosmic duty.
