 During the summer of 1966, Feyerabend lectured on church dogma at Berkeley. (“Why church dogma? Because the development of church dogma shares many features with the development of scientific thought” (pp. 137–8)). He eventually turned these thoughts into a paper on “Classical Empiricism”, published in 1970, in which he argued that empiricism shared certain problematic features with protestantism. He had already come some way from his 1965 defence of a “disinfected”, “tolerant” form of Empiricism. The publication, in 1969, of the four-page article, “Science Without Experience”, which argued that in principle experience is necessary at no point in the construction, comprehension or testing of empirical scientific theories finally gave notice that Feyerabend was no longer concerned to present himself as any kind of empiricist.
