Paul Feyerabend

Feyerabend taught philosophy of science at Bristol starting in 1955, then spent three decades at Berkeley from 1958 onward, holding joint appointments across London, Berlin, Yale, Auckland, and Zurich along the way. Against Method arrived in 1975 with the claim that no single methodological rulebook governs scientific inquiry, a position he expanded in Science in a Free Society three years later. His later books - Farewell to Reason, Three Dialogues on Knowledge, the posthumous Conquest of Abundance - ranged across ethics, ancient philosophy, art, politics, medicine, and physics, while an unfinished history of natural philosophy from Homer to the mid-20th century appeared in 2009. He finished his autobiography, Killing Time, on his deathbed in 1994. A 2010 poll ranked him the eighth most significant philosopher of science of the century, and an asteroid now carries his name.
