On Heidegger's Fundamental Mood--anxiety

Man's probing into self is a permanent subject of philosophy research , the thought that man is rational is the mainstream of the occidental philosophy. They unanimously fight off moods, although they acutely dispute whether man occupies ration from a prior or not . Some philosophers think that moods interferes man's cognition and hinders man's pursuing summum bonum. Man need conquer moods to obtain gnosis and tend towards summum bonum .What's more, Someone thinks when moods eliminated totally, man can gain truth and goodness.Is moods really so harmful that has to be completely eliminated? However, can we completely eradicate moods? Or say, can moods be separated from being-self? Then doesn't the one who completely separated from moods really have any mood? Yet non-moods is also moods?Heidegger answers these questions and annotations moods in a new view. He thinks moods is fundamental ontology of Dasein. Man has moods, even if non-moods also expresses moods. Moods determines and adjusts the way of being. Man as comprehension of being is called as Dasein especially by Heidegger and Dasein interacts with the world in care. Angst is the fundamental mood of Dasein that force Dasein to make a choice between truth being and non-truth being. The call of conscience testimonies the choice of Dasein. Heidegger's dissertation of moods points out a new direction in the road of probing into self and the world .This article consists of five parts. The first part explains that why I choose and study the theme—moods.The dissertations of moods in the philosophy history are put in order in the second part. I think it is necessary, because the dissertations of history can foil the new and special thought of Heidegger. There is an analysis of Heidegger'thought in the third and fourth part which is the hardcore of the article. The two parts actually belong to one which is divided into two parts because of the structure of the article. The influence of Heidegger'thought is mentioned in the fifth part. A big gap exists between his study and conduct. The relationship between Husserl and Nazi and Heidegger is disputed by the people , however , his thought has a strong influence over the contemporary society.
