1924 – 1994
Paul Feyerabend (1924–1994) was an Austrian-American philosopher of science known for his radical critique of scientific methodology. In his landmark work Against Method (1975), he argued that no single scientific method governs scientific progress and that science advances through methodological pluralism and rule-breaking. His 'epistemological anarchism' challenged both logical positivism and Popperian falsificationism, making him one of the most provocative figures in 20th-century philosophy of science.
