Humanity and Self-preservation. Kant or Heidegger?

Kant’s practical philosophy revolves around the concepts of pure reason, autonomy, law and obligation. But for them, terms such as humanity and self-mastery (Selbstherrschaft) are also of great importance. According to Kant, these terms concretize the reason and goal of our ethical and legal-political actions. In a first step, the meaning of these terms at the end of the four Kantian questions (What can I know? What should I do? What can I hope? What is man?) is explained. In a second step, Martin Heidegger’s criticism of humanism (and thus also of Kant) is presented and in a third step the consequences that his view of thinking has for law and politics are discussed: Heidegger’s thinking stands with his negation of philosophy, ethics and science in the service of a politics of immaturity.
