The names of Martin Heidegger and Hannah Arendt do not need to be explained, they have long been included in the pantheon of world philosophical thought. The more interesting is the biographical detail that connected these two people. Their relationship went beyond teacher-student contacts (X.) Arendt was a student of M. Heidegger at the University of Marburg). The novel, which lasted 4 years (since 1925), turned into a friendship that endured a huge temporary break (until 1950). Hannah Arendt retained for the rest of her life warm friendship with the philosopher and put all her strength, all her energy, so that the name of Martin Heidegger was cleared of accusations of complicity in Nazism. Correspondence of two prominent thinkers became available to the reading audience in 1998, when the first edition of a collection of letters prepared by the German researcher Ursula Ludz . was published. Translated by third edition 2002.
