His emphasis was mainly on the language, which is used as the vehicle and stressed upon the importance of poetry in life, time and human existence. His argument is that while analyzing the worldhood of the world, it is not possible to do so without bringing Being-in-the-world into focus as the worldhood depends on mankind and Dasein remains in permanent focus while doing so. Heidegger has taken the philosophy as Phenomenological Ontology and was influenced by Husserl and took some of his ‘phenomenological reduction’. Before his famous Die Kehre, he said we are involved in this world’s affairs by developing ‘the phenomenological attitude’, and our consciousness could be analyzed by both detachment and involvement. Despite his veneration of Husserl, Heidegger wrote Being and Time as a strong criticism of phenomenology as detailed by Husserl. He started with questioning what being is and never stopped analyzing this theme throughout his illustrious career. He argued that western philosophy is shallow for not considering the being, but only stating the obvious. He said the question of Being is a historical argument and this question of Being dominates his book. "Being has entered into the light. Being has arrived in a state of unconcealedness. But whether and how Being itself involves such unconcealedness, whether and how it manifests itself in, and as, metaphysics, remains obscure. Being in its revelatory essence, i. e. in its truth, is not recalled" he says in his Existence and Being. from Existentialism from Dostoyevsky to Sartre edited by Walter Kaufman. His argument was to understand the Being, we should first understand ‘the human kind of being’ which he coined as Dasein (Being-there) and this human being is adept in asking questions. According to his Dasein is ‘uncanny’, which also could be termed as ‘not-at-home’ as Being-in-the-world. One cannot help getting the feeling that Dasein world is populated by physical objects mainly because of the similarity in forms and behavior. He projected the relationship of one humanoid creature with another one similar to that of one with self. This means human beings relate to each other as they relate to themselves. He is of the opinion that humanoid creatures think of themselves as a complete entity and they are outside that entity. Self is seen by him as another humanoid creature. . "The entity which is ‘other’ has itself the same kind of Being as Dasein. Being with and towards Others, there is thus a relationship of Being from Dasein to Dasein. But it might be said that this relationship is already constitutive for one’s own Dasein, which, in its own right, has an understanding of Being, and thus relates itself towards Dasein," (p.162). This means Being of Dasein has a preconceived necessity of Being-with-others because in simple words, Being of Dasein is another way of saying Being-in-the-world. Hence, themes and concepts of Dasein and the world are inter-related and belong to one another. As the world inhabits other similarly formed and behaved humanoid creatures that are also part of Dasein in the same way and intensity as the self, Dasein can only be understood as related to the world and as related to other humanoid creatures.
