David Pearce is a British philosopher of the negative utilitarian school of ethics. He is most famous for his advocation of the idea that there exists a strong ethical imperative for humans to work towards the abolition of suffering in all sentient beings. Many of Pearce's essays can be found online, but he seems not to have published any book in paper, although some of his work like The Hedonistic Imperative could easily make a book. In most of his essays, Pearce details how he believes the abolition of suffering can be accomplished through modern technologies and mainly through genetic engineering. Other technologies that Pearce finds important for abolishing suffering are nanotechnology, pharmacology, and neurosurgery; Pearce believes that these could potentially converge to help humans transform into more enhanced states, first as transhumans and later as posthumans. Pearce lives in Brighton, UK.
