A good overview of the original books. Nonetheless, this guide still does not present a clear exposition of the main ideas Deleuze and Guattari hide under an intricate system of allegories and metaphors. What is a concept? What is science? How can we draw a line of demarcation between philosophy and science? The fact that so many critical companions to Deleuze and Guattari's last book do no highlight a clear solution to the abovementioned questions makes me feel tremendously skeptical towards their work.
