Being and Time by Martin Heidegger (1927)

Today we confront one of the most challenging and consequential philosophical texts of the 20th century, Martin Heidegger's 1927 masterpiece, Being and Time (Sein und Zeit). Heidegger's central project is to revitalize the fundamental question of Being (Sein), a question he argues has been forgotten since the ancient Greeks, by undertaking a detailed analysis of the only entity for whom Being is an issue: Dasein, the term he uses for human existence. . We explore the key structures of Dasein, including Being-in-the-World and the concept of Care (Sorge) as the unifying structure of Dasein. The analysis hinges on Dasein's temporal nature, where the ultimate horizon of human existence is death. We delve into the distinction between inauthentic existence (lost in the "they-self" of the crowd and everyday gossip) and authentic existence (the resolute embrace of one's own finite, unique possibilities in the face of anxiety and nothingness), demonstrating how the entire book is ultimately an attempt to ground the very meaning of Being in Time.
