On Heidegger's Concept Of World

"World" is an old and important philosophical notion, many philosophy researchers explained their points of view from a variety of different perspectives and Heigegger's exposition about the concept of "world" is quite unique and meaningful. Heidegger, one of the most profound, influential philosophers in Western Philosophy, whose thought has become more significant in the west and even the whole world since 1980s. At present, there are a lot of studies about Heidegger in our countries, and there are many associated articles published every year which are mainly dedicated to the research of the Concepts of Existence, Time, Truth, Phenomenology, Hermeneutics, and Linguistics and so on. The author, basing on the previous studies and using the method of theoretical analysis, discusses Heidegger's early and late concept of "world" in detail from the perspectives of the relationships of being-in and the world in Being and Time.The study mainly starts the discussion of Heidegger's concept of "world" from four parts:The first part is about the raise of Heidegger' concept of "world", and has a analysis on the thinking of the concept of world of the previous philosophers. In Heidegger's opinion, the traditional philosophy always regarded the world as the total of beings, because of this thought, the researchers had never discussed the structure of being-in from phenomenology's "from the thing itself". On the concept of "world", only with the method of phenomenology and from the position of existential ontology, can the world be understood as the beginning of phenomenon, and then transcended the category of traditional philosophy. As the part of discussion and analysis, whose function is analyzing the related concept of world preceding Heidegger and playing a role of foreshadowing for the following researches.The second part focuses on the detailed discussion of Heidegger's early concept of "world". At the early age, Heidegger discussed the concept of "world" from the perspective of existence. In the book Being and Time, Heidegger attributed the existential construction to the world, which is the beginning of being-in, and the world is a link of being-in. According to the analysis of the living being-in, Heidegger wanted to clarified the existence in order to oppose the reason of pre-philosophy period and the tendency of subject, overcome the dualism of traditional metaphysics, and regard the being-in world separated from the natural world as a more primordial existence.The third part explains Heidegger's late concept of "world". In the late, Heidegger thought the world as the unity of "whole of four":the heaven, the earth, the deity and the man, and the man became the guardian rather than the main body of the world. And the God's role was fully recognized. Therefore, Heidegger thought philosophy and all human thoughts and attempts cannot cause any direct change of the status quo of the world, only left the God as the ultimate savior.The fourth part mainly described the major compact and practical significance of Heidegger's concept of "world" Heidegger's early and late opinions about the "world" are different:in his early thought, the alive world being-in existed equivalent to being-in and the "world" in the word game is a part of the whole, human only one of those elements. We can discover.that the focus on human's existence, world and the significance of existence has always run through Heidegger's philosophical thought, which provides a new platform for a better understanding of the relations between human and the world. He originally pointed out the concept that the world is a theory of survival, the "world" is not a static contemplation object, it is the environment domain of being-in, which should be understood as the existence of the specific meaning of the whole from the ontology. The relationship of being-in and the "world" is neither a category of pure concept nor purely physical interaction. The traditional ontology thought the prepositional existence as the highest primitive and then generated the entire world. In Heidegger's opinion, the world is the significant presentation of dynamic patterns and it is the source of strength to start the lives of all the other things. Heidegger's concept of world is in the field of vision, which has ontological significance, its innovative ideas and the change of thinking to overcome the traditional metaphysics opens a new chapter for the western philosophy. In the work Being and Time, being-in and the world are linked closely and cannot be separated, without being-in, there is no world, it integrates with the world and exists harmoniously. Heidegger's thought about the concept of "world" make us have a better understanding of the existing problem, and explore the true state of man and the people and the world, show us a harmonious and beautiful scenery.
