David Pearce

David Pearce is a prominent figure within the transhumanism movement and one of the co-founders of the World Transhumanist Association, currently rebranded and incorporated as Humanity+, Inc. He approaches ethical issues from a lexical negative utilitarian perspective.

Based in Brighton, England, Pearce maintains a series of websites devoted to transhumanist topics and what he calls the "hedonistic imperative", a moral obligation to work towards the abolition of suffering in all sentient life. His self-published internet manifesto, The Hedonistic Imperative (1995), outlines how pharmacology, genetic engineering, nanotechnology and neurosurgery could converge to eliminate all forms of unpleasant experience from human and non-human life, replacing suffering with "gradients of bliss". Pearce calls this the "abolitionist project".

In 1995, Pearce set up BLTC Research, a network of websites publishing texts about transhumanism and related topics in pharmacology and biopsychiatry. He published The Hedonistic Imperative that year, arguing that "[o]ur post-human successors will rewrite the vertebrate genome, redesign the global ecosystem, and abolish suffering throughout the living world."

Pearce's ideas inspired an abolitionist school of transhumanism, or "hedonistic transhumanism", based on his idea of "paradise engineering" and his argument that the abolition of suffering—which he calls the "abolitionist project"—is a moral imperative. He defends a version of negative utilitarianism.

He outlines how drugs and technologies, including intracranial self-stimulation ("wireheading"), designer drugs and genetic engineering could end suffering for all sentient life. Mental suffering will be a relic of the past, just as physical suffering during surgery was eliminated by anaesthesia. The function of pain will be provided by some other signal, without the unpleasant experience.

A vegan, Pearce argues that humans have a responsibility not only to avoid cruelty to animals within human society but also to redesign the global ecosystem so that animals do not suffer in the wild. He has argued in favour of a "cross-species global analogue of the welfare state", suggesting that humanity might eventually "reprogram predators" to limit predation, reducing the suffering of prey animals. Fertility regulation could maintain herbivore populations at sustainable levels, "a more civilised and compassionate policy option than famine, predation, and disease". The increasing number of vegans and vegetarians in the transhumanism movement has been attributed in part to Pearce's influence.

In 1998, Pearce co-founded the World Transhumanist Association, known from 2008 as Humanity+, with Nick Bostrom. Pearce is a member of the board of advisors.

Pearce is also a fellow of the Institute for Ethics and Emerging Technologies, and sits on the futurist advisory board of the Lifeboat Foundation.Until 2013, he was on the editorial advisory board of the controversial and non-peer reviewed journal Medical Hypotheses. He has been interviewed by Vanity Fair (Germany) and on BBC Radio 4's The Moral Maze, among others.
