Martin Heidegger is one of the most important philosophers of the 20th century. Interest in his thinking and his persona remains unbroken. Derrida, Foucault, Adorno, Blumenberg, Deleuze - all of these thinkers, who have themselves become famous, have engaged intensely and critically with Heidegger's work. Heidegger's writings are among the most complex, particularly due to their linguistic structure. For those who do not wish to tackle "Being and Time" right away, this text provides entertaining and clearly understandable answers to the most important questions. How do Being and Dasein differ? What role does death play in Heidegger's philosophy? What significance does technology have, which Heidegger understood as "Gestell," a fundamental perspective on the world? Why did he collaborate with the National Socialists? In addition to these fundamental explanations, we also encounter many anecdotes.
