Abstract: The phenomenological method played a decisive role in the growth of Heidegger’s original thoughts. For him, phenomenology firstly and mainly was a kind of method. Heidegger’s phenomenology was formed in three stages of his early Freiburg and Marburg lectures, and the book of Being and Time. He ordinally put forward these important ideas: the phenomenology of formal display, the hermeneutic phenomenology of factual life and phenomenological reduction, deconstruction and construction. These thoughts have had the far-reaching influence on the development of the phenomenological movement and contemporary hermeneutics.
