David Pearce is a British visionary who promotes the abolition of suffering in all sentient life.
Pearce's views are most prominently presented in The Hedonistic Imperative, a manifesto in which he outlines how genetic engineering and nanotechnology will ultimately, and permanently, eliminate all forms of aversive experience.
Pearce was co-founder (with Nick Bostrom) of the World Transhumanist Association.
