Martin Heidegger's seminal work, 'What Is Called Thinking?', delves into the fundamental question of the nature of thought itself. This profound philosophical inquiry challenges readers to reconsider their understanding of thinking, not merely as a cognitive process, but as a deeper engagement with being and truth. Heidegger critiques traditional metaphysics and science for overlooking the essence of thinking, guiding the audience through a rigorous exploration of poetry, language, and the history of Western philosophy to reveal the true calling of human thought. It's an indispensable text for students of phenomenology, existentialism, and anyone seeking a more profound grasp of human existence and its relationship with understanding.
