Abstract
The article is devoted to an investigation of the preconditions of Heidegger’s methodological atheism, according to which “philosophy is fundamentally atheistic”. Based on biographical evidence which sheds light on the mental experience of the young philosopher (“darkness of depressive sensitivity”, according to H. Ott) the author maintains that Heidegger was very prejudiced against the Catholic tradition. The author suggests that the origins of Heidegger’s methodology should be sought in the first and most important of the “turns” which took place around 1916, when Heidegger was in deep crisis. Two main components can be distinguished in this religious-philosophical turn: (1) the rejection of Catholicism, linked to a youthful experience of dependence on the church that stretched over decade; (2) the Protestant influence of his wife and teacher (but no less so of Luther and Kierkegaard) along with the existential experience of the First World War, in which Heidegger became involved. As a result, the author concludes that Heidegger chooses philosophy as opposed to theology, which sets up a specific understanding of philosophy and a negative attitude towards theology. According to Heidegger, only by renouncing ungenuine religiosity one can stand honestly before God, but this “purifying atheism” ultimately leads not to God, but to Nothing.
