This book systematically studies Heidegger's thoughts on the criticism of the modern representational world and is divided into five parts. In the eyes of Heidegger, factual practical actions construct the world of representation in an objectified way, and only practical activities in the existential sense can break away from the shackles of objectification and pursue the origin of beings themselves. This book starts from the origin of ancient Greek metaphysics and explores the process by which the intrinsic meaning of existential philosophy is gradually annihilated by the way representation is constructed. This process reached its peak in the development of modern Juche philosophy, and then formed the representational world dominated by modern science.
