I struggle with Feyerabend a bit. First, a big part of that book is case studies and the problem with case studies is that they are not representative of the underlying population. It’s very easy to simply cherry pick examples that advance your thesis, whereas what we really care about is population averages.

Second, let’s assume there is no method for arriving at truth. Well then how do we verify that some discovery is actually a discovery? Presumably if there was a way to do this, we could incorporate it into our method, thus undermining Feyerabend’s thesis. Well it turns out that his answer to this is to say that evaluation should consist entirely in the contribution of the discovery to happiness and flourishing. This could be useful at a general level, but seems useless when it comes to judging between theories and research paths within science.
