ABSTRACT
In this chapter the authors point out that, just as politically, everything is permissible is a paralytic principle in politics. And morally, everything is permissible is in morals, so cognitively, everything is permissible is a paralytic principle in epistemology. "Anything goes", or cognitively, everything is permissible, is a paralytic principle; and just as the dreamer finds all his physical energy gone in nightmares, so Paul Feyerabend should not be surprised if, having adopted cognitively, everything is permissible, he finds in epistemology that all his screams are soundless. Feyerabend took his slogan "Anything goes" from one popular entertainer, Cole Porter, and his philosophy with trifling amendments, from another, Sir Karl Popper. Another Cole Porter song title, "What is this thing called Love?" slightly amended, furnished another neo-Popperian philosopher with a title for his book". And these conjunctures are no accident: here, as always, deep calls to deep.
