Abolitionism, in bioethics and transhumanism, is a proposed programme to prevent or eliminate involuntary suffering in sentient beings. It combines the ethical claim that avoidable suffering should not be accepted merely because it is natural with the technological hypothesis that pain and negative affect could eventually be redesigned. Its strongest versions seek a future in which no sentient being undergoes an experience with negative valence.

The modern formulation is principally associated with British philosopher David Pearce. In The Hedonistic Imperative (1995) and the later Abolitionist Project, Pearce argues that biotechnology could replace motivation based on pleasure and suffering with gradients of well-being: agents would remain sensitive to better and worse states, but their lowest states would be positive. The proposal is more ambitious than conventional pain management or mental-health care, which abolitionists support as nearer-term means.

Abolitionism is not a single theory, organisation or settled platform. It overlaps with utilitarianism, animal ethics and consciousness research, but proponents disagree about foundations, interventions and timescale. As of 2026, medicine can relieve many forms of pain and distress, but no intervention can safely abolish all human suffering, still less suffering across species or artificial substrates. The complete project remains speculative.

Origins and philosophical basis

The moral ancestry of abolitionism includes traditions that prioritise suffering. Buddhism places dukkha at the centre of ordinary existence, while utilitarians from Jeremy Bentham onward have treated the capacity to suffer, rather than species, as morally important. Modern abolitionism makes technological control of experience central.

Pearce's position begins from physicalism: painful and pleasant experiences depend on physical processes and should therefore be alterable by changing those processes. Evolution by natural selection did not optimise organisms for happiness. Pain, fear, jealousy, hunger and low mood persisted because, in ancestral environments, they often helped organisms avoid threats, compete, reproduce or conserve energy. Abolitionists infer that an evolved trait's former adaptive value does not establish its permanent necessity or moral desirability.

The ethical case does not require one exclusive theory. A negative utilitarian may give suffering reduction overriding importance; a classical utilitarian may support abolition as part of maximising well-being; and a rights-based account may emphasise protection from extreme, non-consensual harm. Pearce argues that pluralists could preserve projects, autonomy and achievement while removing their most aversive phenomenology. Critics dispute both the priority and the assumption that other values would survive large changes to affective life.

The term abolition is deliberately stronger than alleviation. Nevertheless, there is a continuum between ordinary humanitarian work and radical abolition: anaesthesia, analgesia, psychiatric care, violence prevention and animal-welfare reform already remove experiences once regarded as unavoidable. The abolitionist project is distinguished by its universal scope and proposed endpoint, not by rejection of present interventions.

Scope

The unit of moral concern is normally sentience - the capacity for experiences that can feel good or bad - rather than humanity alone. On this view, the programme has three potential domains:

• Humans. Immediate goals concern severe physical pain and psychiatric distress; long-term proposals concern baseline mood and valence.
• Non-human animals. The scope includes domesticated, research and wild animals exposed to injury, predation, disease or hunger.
• Artificial minds. If future systems become conscious and capable of valenced experience, their welfare would fall within the same moral circle. This remains conditional.

Institutions associated with abolitionism occupy different positions. The former Foundational Research Institute, now the Center on Long-Term Risk, studies severe suffering in the long-term future, including advanced-AI risks; it does not make Pearce's biomedical programme its sole strategy. The Qualia Research Institute, co-founded by Andrés Gómez Emilsson, researches consciousness and emotional valence. This could inform abolitionism, but does not endorse a particular intervention.

Proposed technological pathways

Abolitionist writing discusses several partly overlapping pathways. Pharmacology and brain stimulation could provide relatively reversible control of mood or pain; genetic and epigenetic interventions might alter enduring predispositions; cell therapy, neural prostheses and future precision neuromodulation might change particular circuits. Pearce rejects indiscriminate wireheading as a general solution because constant undifferentiated reward could destroy responsiveness to information and undermine agency. His preferred model is an affective range that continues to encode success, error and urgency while remaining above a neutral hedonic floor.

Existing research shows that components of pain are biologically modifiable, but not that suffering as a whole is close to abolition. The International Association for the Study of Pain defines pain as an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage. It also distinguishes pain from nociception, the neural processing of noxious stimuli. This distinction leaves open, in principle, systems that detect damage and trigger protective behaviour without producing agony.

One research target is the voltage-gated sodium channel NaV1.7, encoded by SCN9A. In mice, targeted repression of NaV1.7 using CRISPR-based epigenetic tools produced long-lasting reductions in several pain responses. This was a preclinical analgesia result, not evidence that human pain or negative affect can be globally removed. Psychological suffering involves distributed and interacting systems for threat, reward, memory, social cognition and bodily regulation, so it is unlikely to yield to a single-gene intervention.

Twin and family studies indicate that differences in subjective well-being are partly heritable, but heritability is a population statistic, not a fixed individual destiny or a map to a simple happiness gene. A meta-analysis found genetic contributions across multiple components of well-being as well as heterogeneity among measures and samples. An abolitionist technology would therefore have to address developmental and environmental interactions as well as genes.

Functional role of pain and negative affect

The central engineering problem is not merely to suppress a signal, but to preserve the useful work that signal performs. Acute pain can interrupt action, protect an injured body part and teach avoidance. Anxiety can direct attention to uncertain threats; disappointment can update choices; guilt can help regulate social behaviour. Chronic pain, major depression and post-traumatic distress, by contrast, can persist after any protective benefit has disappeared and can impair the very agency those systems evolved to support.

Congenital insensitivity to pain illustrates the danger of deletion without replacement. People born unable to perceive pain can accumulate unnoticed burns, fractures, joint damage, infections and corneal injuries. Abolitionists consequently need a substitute architecture: reliable damage detection, learning and rapid corrective action without the felt awfulness of pain. Gradients of well-being are one proposed answer, but they have not been engineered or demonstrated as a complete motivational system.

Related risks include mania, addiction, tolerance, compulsive reward seeking and impaired judgement. A safe intervention would have to distinguish durable well-being from euphoria that overrides other preferences, while preserving recognition of others' distress during the transition. The project is therefore a problem in cognitive architecture and governance, not simply one of increasing reward-pathway activity.

Non-human animals and ecosystem redesign

Some proposals apply biotechnology first to animals under direct human control. Adam Shriver has argued that reducing the affective component of pain in livestock might improve welfare where husbandry reform has stalled. Such modification would still need regulation and should not legitimate harmful production systems.

The strongest version extends intervention to wild nature, sometimes called paradise engineering. It rejects the inference that predation, starvation or high juvenile mortality are acceptable merely because they occur without human authorship. Suggested responses range from vaccination and fertility control to far-future ecological redesign.

Ecosystem interventions can shift rather than eliminate harms: suppressing predation can increase hunger or disease, while fertility or genetic changes can affect non-target populations. This creates tension between individual welfare and environmental values such as biodiversity and ecological autonomy. Field interventions would require modelling, staged trials, reversibility where possible and long-term monitoring.

Artificial minds

Abolitionism becomes relevant to computing if artificial systems can have conscious states with positive or negative valence. Digital systems could potentially be copied or run at great speed, so even a small probability of machine suffering might have large consequences. Conversely, engineering new minds without negatively valenced states could avoid reproducing biological suffering at scale.

The premise is unresolved. A multidisciplinary report derived indicators from several theories of consciousness and judged that the AI systems examined were not conscious, while finding no obvious technical barrier to systems that satisfy the indicators. Precaution may justify research, but confident claims about present machine suffering outrun the evidence.

Objections and governance

Objections to abolitionism fall into several groups:

• Value and meaning. Critics argue that grief, struggle or dissatisfaction can contribute to identity, virtue and practical wisdom. Abolitionists answer that responding to unavoidable suffering may have meaning without making suffering intrinsically valuable, and that challenge need not involve misery.
• Autonomy and identity. Personality-altering interventions raise questions about consent and continuity of the self. A voluntary option for competent adults differs ethically from germline modification or alteration of beings unable to consent.
• Distribution. Scarce enhancement could deepen inequality or create pressure to conform to a preferred temperament. Access, disability rights and protection from discrimination are therefore design constraints.
• Power and misuse. States, employers or parents might use mood modification to suppress justified anger or make people tolerate exploitation. Historical eugenics makes germline proposals especially sensitive.
• Uncertainty. Neuroscience lacks a complete causal theory of valence, and apparent benefits may produce delayed harms. Ecological and artificial-mind interventions add uncertainty about sentience and measurement.

These concerns favour voluntariness, independent oversight, transparent evidence, reversibility and post-intervention monitoring. They also favour moving from well-characterised medical need towards speculative enhancement. For beings unable to consent, proponents would need to show a high probability of welfare improvement while protecting health and agency.

Feasibility and measurement

Abolition is not presently a measurable engineering milestone. Self-report remains indispensable for many human experiences, yet it cannot cover infants, many disabled people, non-human animals or hypothetical artificial minds. Behavioural and physiological indicators can be dissociated from felt experience. Cross-species comparisons of intensity are especially uncertain, and there is no validated scale that places every possible biological or artificial subject on a common axis.

A serious research programme would distinguish the prevalence, intensity and duration of negative episodes; the lowest or floor state a subject can occupy; preservation of agency and damage avoidance; and the distribution of harms. Lower average distress would not count as straightforward progress if it concealed injuries or created rare episodes of extreme suffering.

Feasibility varies by target. Treating a defined pain syndrome has clinical endpoints; raising mood without mania is a broader neurobiological problem; and removing all negative valence while preserving flexible intelligence is an untested problem in whole-agent design. Ecosystems and artificial populations add systemic risk. Evidence at one level is not proof at another.

Assessment

Abolitionism is strongest as a moral challenge and research direction: it asks why preventable suffering should remain part of the long-term human, animal or posthuman condition if its useful functions can be separated from its aversive character. The history of anaesthesia, analgesia and mental-health treatment supports its rejection of simple appeals to what is natural. Work on nociception, affective neuroscience and animal welfare provides limited evidence that particular mechanisms can be modified.

Its strongest empirical claim - that all sentient life can safely be moved to gradients of well-being - is not established. Present evidence does not demonstrate a complete theory of valence, a safe replacement for every function of pain and negative affect, or a reliable method for comparing welfare across species and substrates. Claims of inevitability or a definite timetable should therefore be treated as advocacy rather than scientific forecast.

Near-term policy can reduce severe suffering through proven social, medical and animal-welfare measures while supporting cautious research into better analgesia, treatment-resistant psychiatric illness, objective correlates of affect and non-invasive or reversible interventions. The case for radical abolition would become materially stronger if research demonstrated durable control of valence with intact judgement and damage avoidance, replicated safety across long follow-up, credible measures for non-verbal subjects, and institutions capable of preventing coercive or ecologically destabilising use.
