Against method

Against Method: Outline of an Anarchist Theory of Knowledge is a 1975 book about the philosophy of science by Paul Feyerabend, in which he argues that science is an anarchic enterprise, not a nomic (customary) one.
Feyerabend argues that scientific advances can only be understood in a historical context. He looks at the way the philosophy of science has consistently overemphasized practice over method, and considers the possibility that anarchism could replace rationalism in the theory of knowledge.
