Authenticity and Human Existence in Martin Heidegger's Being and Time: A Critical Evaluation

This study critically examines Martin Heidegger’s concept of authentic existence as articulated in Being and Time, with particular attention to the notions of Dasein, Being, temporality, anxiety, conscience, and Being-toward-death. Employing a qualitative philosophical methodology based on textual and conceptual analysis, the paper explores Heidegger's understanding of human existence and evaluates the relationship between authenticity and ontological inquiry. The study argues that Heidegger’s existential ontology offers a profound account of human self-understanding by emphasizing personal responsibility, freedom, and the appropriation of one's existence. However, it also identifies significant limitations, particularly the absence of a robust ethical framework and the exclusion of transcendence from his account of authentic existence. The paper concludes that while Heidegger's philosophy remains foundational for existentialism, phenomenology, and philosophical anthropology, his conception of authenticity requires further dialogue with ethical and theological perspectives to address the broader dimensions of human existence. The study contributes to contemporary Heidegger scholarship by offering a balanced critical evaluation of the continuing relevance and limitations of authentic existence in understanding the human condition.
