How did Martin Heidegger’s later philosophy differ from the Dasein-centered approach of Being and Time?

Martin Heidegger’s later philosophy marked a significant departure from the Dasein-centered approach of his earlier work, Being and Time (1927). While Being and Time focused on a phenomenological analysis of Dasein—the human individual as "being-in-the-world"—to address the question of Being (Seinsfrage), Heidegger later became dissatisfied with this framework.123

Heidegger eventually viewed the concept of Dasein as too closely tied to the subjective and anthropological preconceptions he sought to overcome. He grew concerned that his earlier work had inadvertently suggested that humanity was the "measure of all things" or the author of Being, rather than its recipient. Consequently, his later writings shifted away from the practical, worldly involvements of Dasein toward a more direct, albeit mysterious, contemplation of Being itself.12

Key shifts in his later thought included:
* Critique of Metaphysics and Reason: He increasingly viewed Western metaphysics as riddled with errors and began to distrust reason as an adversary of thought, often turning toward poetry to unveil the mysteries of Being.1
* Focus on Technology: He analyzed how modern technology reduces the totality of Being to a "standing reserve" or raw material for human manipulation.1
* The "Forgetting of Being": He argued that modern life is characterized by Seinsvergessenheit (the forgetting of Being), leading him to adopt a more detached, sometimes mystical perspective on the relationship between gods, men, the earth, and the heavens.1
