This is a very short book with two dialogues on the philosophic problem of the nature of knowledge. Of the two, the second one was, for me, the most interesting and enlightening: it is a dialogue between Feyerabend and a student; it seems to encapsulate Feyerabend's thinking about his work, as well as his critical stance in relation to philosophy, the sciences (and scientific knowledge) and life. It seemed to me a lot less radical than I had expected, but then I had never read Feyerabend before. Maybe I should continue now... ( )
