Being and Time
Martin Heidegger’s *Being and Time* upends traditional Western ontology by centering its inquiry on Dasein—human beings as "beings who question their own existence." Rejecting the long-held view of humans as fixed, ready-made entities, Heidegger argues Dasein’s essence lies in its "to-be"—its dynamic, contextual existence shaped by choices, everyday engagement, and the inescapability of death. Through rigorous existential analysis, he unpacks core concepts: "care" (Sorge) as Dasein’s fundamental structure, temporality as the hidden meaning of care, and the tension between authentic (owning one’s existence) and inauthentic (following the "they") modes of being. He also redefines truth as the disclosure of existence rather than a correspondence between thought and object, and ties human historicity to the temporal unfolding of Dasein. More than a philosophical treatise, it’s a radical invitation to confront the meaning of being by examining how we live, relate to the world, and embrace our finitude.
