Toward an Existancial Ethic, an enquiry concerning Kierkegaard's approach of the tale Abraham according to Heidegger's philosophy

The aim of this paper is to analyse opinions of Kierkegaard in his famous book, Fear and Trembling, and Heidegger’s points of view in the great work of thought, Being and Time, in order to present a new meaning of human. And these all going to introduce the new aspect of Ethic. Kierkegaard puts the act of the faith against of the virtue ethics according to the tale of Abraham in the Bible. He claims that the act of the faith transcends from general ethic with achieve its individuality. The actor of the faith can not returns to generality, as the actor of tragedy can. He leaves the generality to make decision in a free manner. on the other hand, Heidegger’s existancial analyses leads into that the human determiner is not an ideal essence, but it’s his existance, in other word it’s his ability-to-be. Human is who he can be. So it is obvious that these two great thinkers believe that human is not a predestined being, but he is facilities. And for this reason we can renew our definition of the ethic.
