Delueze Study:

Deleuze and Guattari took that up from Friedrich Nietszche’s books, for example Morgenröte (1881), [i]Zur Genealogie der Moral /i, but they probably took that also up from Max Stirner’s book Der Einzelne und sein Eigentum (1844), because (to me) Deleuze’s and Guattari’s anti-genealogical philosophy is more like Stirner’s than Nietzsche’s philosophy. By the way: Max Stirner (actually: Johann Kaspar Schmidt) published his book Der Einzelne und sein Eigentum when Nietzsche was born (1844).
