Paul Feyerabend
Paul Feyerabend (1924 - February 11, 1994) was an Austrian-born philosopher of science, who later emigrated to the US. He began as a follower of Karl Popper, but later went on to reject all attempts to discover rules underlying the scientific method. His most famous works include Against Method (published in 1975), and Farewell to Reason (collection of his papers published in 1987).He argued that descriptions of the scientific method often do not match how scientific discoveries have actually occurred in history. Feyerabend objected to any single prescriptive scientific method on the grounds that science has no single aim. Without a fixed ideology, or the introduction of religious tendencies, the only approach which does not inhibit progress (using whichever definition of progress you see fit) is "anything goes": "'anything goes' is not a 'principle' I hold [...] but the terrified exclamation of a rationalist who takes a closer look at history." (Feyerabend, 1975).
