Works & Achievements
His major work, where he defends “epistemological anarchism” and the idea that science progresses according to no fixed rules. It has become a classic in the debate over scientific rationality.
A sequel to *Against Method*, in which he responds to his critics and argues for the separation of science and the State. He defends the pluralism of knowledge traditions.
A collection of essays defending relativism and criticizing the idea of a universal reason. He questions the West's claim to impose its own rationality.
A collection of his philosophical articles on the theory of knowledge and physics. In it he develops his critique of logical empiricism and the Vienna Circle.
His autobiography, published just after his death, in which he recounts with humor his journey from opera to philosophy. A personal and unsparing account of his life.
A posthumous and unfinished work on the richness of reality that scientific abstractions tend to impoverish. In it he continues his reflection on the limits of science.
Anecdotes
Before becoming a philosopher, the young Feyerabend dreamed of singing at the opera and took voice lessons alongside his studies. Throughout his life he remained passionate about theatre and opera, and he liked to say that science was merely one tradition among others, no more sacred than art.
Drafted into the German army during the Second World War, Feyerabend was severely wounded by gunfire on the Eastern Front in 1945. Hit in the spine, he was left disabled and suffered from chronic pain for the rest of his life, sometimes having to walk with a cane.
His provocative slogan “anything goes” caused an uproar among philosophers of science. Many accused him of being an enemy of reason, but Feyerabend was amused by his reputation as the “worst enemy of science” and gladly cultivated his image as a troublemaker.
Feyerabend and the philosopher Imre Lakatos had planned to write a two-voiced book, “For and Against Method,” in which each would defend his own position. The sudden death of Lakatos in 1974 left Feyerabend on his own: he published his half under the title *Against Method*, dedicated to his late friend.
In his lectures at Berkeley, Feyerabend was a spectacular and unpredictable teacher: he juggled ideas, played devil's advocate and sometimes changed his mind in the middle of an argument. He wanted to push his students to think for themselves rather than accept a ready-made doctrine.
Primary Sources
The idea of a method that contains firm, unchanging, and absolutely binding principles for conducting the business of science meets with considerable difficulty when confronted with the results of historical research.
There is only one principle that can be defended under all circumstances and in all stages of human development. It is the principle: anything goes.
Science is one of the many forms of thought that humans have developed, and not necessarily the best. It is dazzling, noisy, and insolent, but it is superior only to those who have already decided in favour of a certain ideology.
I wanted to be a great opera singer. Philosophy came later, almost by accident, and I never took it entirely seriously as a sacred vocation.

His most famous work, which became a controversial classic of the philosophy of science. In it, he develops the idea that scientific progress follows no single method.

An everyday object made necessary by his wartime spinal injury. He used it to move around despite chronic pain.

The working tool of the twentieth-century intellectual, on which he drafted articles and manuscripts. His sharp, polemical texts came out of it page after page.

A testament to his passion for lyric singing, which he had nearly taken up as a profession. Music remained for him a model of free creation, opposed to methodical rigidity.

The tools of the Berkeley professor, whose spectacular lectures left their mark on generations of students. There he improvised, changed his mind, and played devil's advocate.
