The Genesis of Dasein from Facticity at the Beginning of Heidegger’s Way of Thinking

The present paper aims to show that Heidegger’s concept of “facticity” is the primary form of his Dasein concept. Firstly, it explicates the three components of facticity meaning: 1. the concretion and reality; 2. the human individual characteristics; 3. the historicality which is based on the "averageness" and "everydayness" of Dasein or facticity. The textual bases of the paper are Heidegger’s writings known as Report to Natorp (the beginning of autumn 1922) and his lecture Ontology (The Hermeneutics of Facticity) (summer 1923). Based on these two texts, the paper, secondly, argues that facticity and Dasein are identical, due to their shared characteristics: anxiety, everydayness, death, care, Being-in-the-world, language, temporality, and finally existence. The paper tries to distance methodologically from the current Heidegger’s studies, which are extremely founded on Being and Time.
