I did not see your question regarding the relationship between analytic and post-analytic philosophy. You are correct: It did not come about as a result of a synthesis with continental philosophy. Rather, post-analytic philosophy is a consequence of a single book, Richard Rorty's Philosophy and the Mirror of Nature. The book was perceived to be an attack on analytic philosophy by an analytic insider. This is an overstatement. Nevertheless, the effect of this book and the essays Rorty published the following year as Consequences of Pragmatism was to create a huge crack in the foundation of analytic philosophy. Professionally, philosophy remains an analytic game in the US. The three major journals of philosophy are not refereed. Rather, publication is determined by a board composed entirely of analytically trained professors of philosophy.
