Martin Heidegger’s Being and Time (1927) reexamines the "meaning of Being" through the concept of Dasein, the human way of being that finds itself in the world and defines its own existence. Key themes include authentic existence, the "They" (das Man), and temporality, with prominent guides by Gelven, Blattner, and King aiding in understanding the complex text.
