The Origins of Totalitarianism
Blücher encouraged his wife to become involved with Marxism and political theory, though ultimately her use of Karl Marx was in no way orthodox, as shown in such works as "The Origins of Totalitarianism" (1951) and "The Human Condition" (1958). Blücher also coined the term "the anti-political principle" to describe totalitarianism's destruction of a "space of resistance" — a term taken up both by Arendt and Karl Jaspers.
