David Pearce (born 1959) is a British philosopher and co-founder of the World Transhumanist Association (now Humanity+), best known for his 1995 manifesto *The Hedonistic Imperative*, which argues that biotechnology should be used to eliminate all suffering in sentient life. His work is a foundational text of the [[Transhumanism]] movement and connects to the broader [[TESCREAL]] ideological cluster through its vision of using technology to radically reshape the human condition, influencing both [[Effective Altruism]] and [[Longtermism]].
