Editing Paul Feyerabend (section)

====Departure from Popper====
Beginning in at least the mid-to-late 1960s, Feyerabend distanced himself from Popper both professionally and intellectually. There is a great amount of controversy about the source and nature of Feyerabend's distancing from Popper.<ref name=Collodel/> Joseph Agassi claims that it was caused by the student revolutions at Berkeley, which somehow promoted Feyerabend's move towards epistemological anarchism defended in the 1970s.<ref name=Agassi>{{cite journal|last=Agassi |first=Joseph |title= As you like it|journal= The Gentle Art of Philosophical Polemics: Selected Reviews and Comments |date=1980 |pages=422–4}}</ref> Feyerabend's friend Roy Edgley claims that Feyerabend became distanced from Popper as early as the mid-1950s, when he went to Bristol and then Berkeley and was more influenced by Thomas Kuhn and the [[Marxism]] of David Bohm.<ref name=Edgley>{{cite journal|last=Edgley |first=Roy|title= Anarchy in Academia |journal= New Left Review| pages= 155–156}}</ref>

Feyerabend's first paper that explicitly repudiates Popper is his two-part paper on Niels Bohr's conception of [[Complementarity (physics)|complementarity]].<ref name=PKF19682>{{cite journal|last=Feyerabend |first=Paul |title= On a Recent critique of complementarity: part I |journal= Philosophy of Science |date=1968| volume=35|issue=4|pages= 309–331|doi=10.1086/288226 |s2cid=170776675 }}</ref> According to Popper, Bohr and his followers accepted complementarity as a consequence of accepting positivism. Popper was the founder of the theory of falsification, which Feyerabend was very critical of. He meant that no science is perfect, and therefore cannot be proven false.<ref>{{cite book |last1=Andreasson and Johansson |first1=Jesper and Thomas |title=Vetenskapsteori: grunder och tillämpning |date=2020 |publisher=Studentlitteratur |location=Lund |isbn=978-91-44-18508-8 |pages=66–67 |edition=2nd}}</ref> Once one repudiates positivism as a philosophical doctrine, Popper claims, one undermines the principle of complementarity. Against this, Feyerabend claims that Bohr was a pluralist who attempting to pursue a realistic interpretation of quantum mechanics (the [[BKS theory|Bohr-Kramer-Slater conjecture]]) but abandoned it due to its conflict with the Bothe-Geiger and Compton-Simon experiments.<ref name=Shaw2018>{{cite journal | last = Shaw | first = Jamie | title = A Pluralism Worth Having: Feyerabend's Well-Ordered Science | journal = Electronic Thesis and Dissertation Repository | publisher = University of Western Ontario (doctoral dissertation) | year = 2018 | pages=38 |url = https://ir.lib.uwo.ca/etd/5599/}}</ref> While Feyerabend concedes that many of Bohr's followers (notably, [[Leon Rosenfeld]]) accept the principle of complementarity as a philosophical dogma, he contends that Bohr accepted complementarity because it was entangled with an empirically adequate physical theory of microphysics.
