Paul Feyerabend was one of the most original thinkers of the 20th century, particularly renowned for his work in the philosophy of science. Though occupying academic positions across the globe, he spent much of his time as professor at the University of California, Berkeley. In his most famous and polemical book, Against Method (1975), Feyerabend rejects the idea of a single scientific method, arguing that both anarchy and subjectivity are essential for true scientific progress. Later works include The Tyranny of Science (Polity, 2011), which exposes the way that scientific ideologies negatively impact on society by valuing theory and abstraction above subjective experience, and Philosophy of Nature (Polity, 2016), a recently rediscovered manuscript exploring the interconnections between myth, philosophy and science, from Homer to Einstein. Feyerabend's ideas remain highly relevant to philosophers, scientists and social theorists alike, transforming our understanding of the relationship between science and society.
