I got my first inklings of this some years ago, as a philosophy student, when I became aware of an academic controversy over revelations that two influential 20th-century philosophers — Martin Heidegger and Paul de Man — were Nazi sympathizers. Most of the controversy centered around whether this involvement with Nazism (Heidegger joined the Nazi Party, while de Man expressed sympathy for the Nazi cause) detracted from the value to be found in their philosophical work. But few comments addressed the philosophical similarity between Nazi ideology and the ideas of these two philosophers.Nazis, agents of Multiculturalism? Would've thunk?
This is a crucial question, because Heidegger and de Man were two founders of the most influential contemporary school of philosophy, called "Deconstruction," which has provided the theoretical foundation for Multiculturalism.
In its essence, Deconstruction is an assault on reason in favor of the same dogmatic subjectivism held by the Nazis.
