When Heidegger deals with death as Dasein's non-relational, ownmost possibility in Being and Time he distinguishes between free selfhood and the they-self. He suggests a way of embracing man's mortality and finitude which avoids the mediocrity of the inauthentic. But what does authentic resoluteness mean? Am I to live according to the destiny of my fate? Is Heidegger implying that we should live our lives as if it were a work of art as interpreted even in the Nietzschean sense?
Formally, resoluteness only means being resolute to not flee from the call of Dasein in the Stimmung of Angst. And it is only formal, Heidegger provides no contents.
This is (a.o.) because Sein und Zeit is a preparation for the question to the sense of Being (Sinn von Sein). To do this, you need to be ready (bereit) to hear the call of your own being. Your own being does not only include your fate, but also your possibilities (of which death is the utmost).
Live as a work of art is something only Nietzschean. Remember 'art' means someting different for Nietzsche than for Heidegger:
- For Nietzsche, art is a creation of the will. Life as a work of art for him means creating and experimenting with new values to find those which allow you to affirm life.
- For Heidegger, a work of art is an event of truth (Unverborgenheid).
The resoluteness vis-a-vis a work of art in The Origin of the Work of Art is, as he says, a kind of 'knowing'. What can occur in a work of a art that it tears you from the immersion into the world of beings to the openness of Being. It allows you to know Being. 'Standing within' (Inständigkeit) does not mean that you live as the work of art, but to allow yourself to be open to the event of the work of art.
