Jean Yves-Girard's thinking evolved from analytic philosophy to continental philosophy over the course of his life, and in this book in particular, some of his asides and polemics critique how we conceptualize truth, knowledge, and logic, and how other fields conceptualize that stuff, from a continental perspective. The fact that this kind of stuff turned up in a mathematical logic book of all places really struck me. It put me on a path to taking a more serious interest in the continental school, and reading more of it (currently chewing on Gilles Deleuze and Bruno Latour). It's a very unusual and difficult book, that led me to very different (compared to what I am used to, anyway) modes of thinking.
