Meaningfulness of Life from the Former Heidegger's Point of View

Philosophy of Heidegger is concerning to the question of meaning of existence, and the starting for its response should begin from the existence of own questioner. In former Heidegger’s thought, it can be found two main virtues for Dasein. First, one person is essentially an actor or doer. Human personality and the world are not separable. Hence, Heidegger explains this fact as Being -in- the World. Second, Dasein’s personality is explained by Being- in- the- Other- People. So, it should be considered that does Heidegger’s philosophy separates meaningfulness life from meaningless one or not? And that how meaningfulness life can be explained? Reviewing of former Heidegger shows that he separates meaningfulness life from meaningless one, and also makes meaning relation between cultural heritage and meaningfulness of life. Therefore, for Heidegger hegemony of others on Dasein and following public style is not authentic. Thinking of death guides Dasein to authentic life, and that meaningfulness life is the same as authentic life. The context of meaningfulness life, also, is discovered through cooperation of cultural heritage and human facticity on him/her.
