David Pearce is co-founder of the World Transhumanist Association, currently rebranded as Humanity+, Inc., and a prominent figure within the transhumanism movement. He is a philosopher, vegan and writer on transhumanist and ethical subjects and an advocate of abolitionism.
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 book-length 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." 
Pearce has answered more than 400 questions on Quora, and his answers have been viewed more than three quarters of a million times.
Pearce has over 100,000 followers on Twitter, making him, by one assessment, the fourth most popular philosopher on that site.
A collection of essays by Pearce is available in the book "Can Biotechnology Abolish Suffering?"
