Who was Paul Feyerabend?
An influential and highly controversial philosopher of science
In my previous post, I used Paul Feyerabend as an example of a contrarian, and I’ve mentioned and quoted him before. A short summary of Fayerabend and his controversial views seemed fitting for a post.
Paul Feyerabend (1924–1994) was an Austrian-born philosopher of science. Permanently disabled after being shot three times during World War II and earning his Ph.D. from the University of Vienna, he spent most of his career as a professor at the University of California in Berkeley. He became one of the most famous and polarizing thinkers of the 20th century, particularly known for his 1975 book Against Method.
Feyerabend's philosophy was deeply critical and radical. He rejected the notion that science is the only or best way to understand the world. Here are some of his core ideas:
Feyerabend argued against the idea of a universal scientific method, asserting that fixed rules limit creativity in scientific discovery. He believed significant advances often occur when existing rules are broken, coining the phrase "anything goes" to suggest that any approach leading to valuable results is valid.
He opposed the idea that science must adhere to a single set of rules. Instead, he supported "methodological pluralism," where diverse and even conflicting methods coexist, fostering innovation in science.
He questioned the notion that science represents ultimate rationality or objective truth. He argued that science is influenced by historical, social, and ideological factors and warned against it becoming an unquestionable authority over other forms of knowledge.
He promoted "theoretical pluralism," where multiple, even contradictory, theories are upheld to encourage alternative perspectives and new insights. He saw scientific progress as arising from competing theories rather than from the linear accumulation of facts.
He extended his pluralistic philosophy to include indigenous knowledge and religious traditions, arguing that these also possess rational validity. He criticized Western science for dismissing other knowledge systems as inferior and called for respect for cultural diversity.
He was concerned about the authoritative role of science in society, comparing it to a modern ideology. He advocated for separating science from the state to prevent it from becoming coercive, similar to the separation of church and state.
He criticized philosophers Karl Popper and Thomas Kuhn for their attempts to define a universal model of science, arguing that such models oversimplify the complexities of real scientific practices.
While not necessarily endorsing pseudosciences, Feyerabend defended the exploration of alternative theories to challenge the monopoly of science on truth. He noted that some pseudosciences have historically contributed to genuine scientific advancements.
He criticized the rigidity and dogmatism of scientific education, advocating for an approach that fosters critical thinking, creativity, and an understanding of the historical context of scientific theories.
Feyerabend opposed "scientism," the belief that science is the ultimate authority on truth. He argued that this stance marginalizes other ways of understanding and poses a philosophical and political threat to a diverse society.
Feyerabend's ideas are highly controversial and fiercely debated because they fundamentally challenge the prevailing views on the nature of science, knowledge, and rationality. His philosophy of "epistemological anarchism" questioned the authority and special status of science, which many consider the most reliable and objective means of understanding the world.
His provocative writing and lecturing style, use of biting humor, and confrontational rhetoric often alienated the scientific community. He likened modern science to a "myth" and its practitioners to "witch doctors," which was seen as an affront to scientists and philosophers alike. His harsh critiques of prominent philosophers of science Karl Popper, Thomas Kuhn, and Imre Lakatos sparked intense debates, as he argued their theories oversimplified the complex nature of scientific practice.
Feyerabend's defense of pseudosciences such as astrology and his critique of science's monopoly on truth were often misunderstood as endorsements of these practices. Critics feared his views could legitimize pseudoscientific beliefs and weaken public understanding of science, potentially leading to non-scientific ideas being taught alongside established science. His call for a separation of science and state was also seen as undermining the role of science in informing public policy, raising concerns about its misuse by anti-science movements on critical issues like climate change and public health.
As a big fan of Kuhn and Popper, particularly Popper’s test of falsification, I think it’s useful to keep Feyerabend in your epistemological toolkit in case you run into situations like Heinrich Schliemann (Troy) and Alfred Wegener (Plate Tectonics). I’m not sure that Astrology works unless there’s a link between orbital mechanics and entanglement at inception.
Thanks for an interesting write-up. Berkeley was something else. Feyerabend said indigenous knowledge is on par with science, but then he criticized scientists by calling them witch doctors. That's like a gay rights advocate criticizing homophobes as "gay".
