QUOTE : Freedom can no longer be either "essential" or "existential", but is implicated in the chiasmus of these concepts: we have to consider what makes existence, which is in its essence abandoned to a freedom, free for this abandonment, offered to it and available in it ... But if the essence that is offered to existence does not in some way "free" existence in its most proper essence, then thought has nothing left to "think" and existence has nothing left to "live": the one and the other are stripped of all experience.
