Where we are not conscious of our own existence. We bcome conscious of our existnce only through certain experiences, like that of anguish, which put us in the presence of the background of Nothingness from which Being erupts. This is an active Nothingness which causes the world which erupts from it to tremble to its foundations. Be ng detaches itself from this nothingtness by a kind of rupture. This is what existencesignified.
Existence is essentially .estatic.
In contrast to Descartes who cast doubt on the world's reality, we are always open to the world. Even when we think we are most alone, we are not separated from others. Each of us is always planning, oriented toward our possibilities, projecting ourselves into the plan. Thus it is that we are always filled with anxiety or care. We are always concerned with something yet to come.
