Lucidity separates a person from immediate participation in life. It lets you watch yourself act, and that splits the self and poisons spontaneity. The more clearly one sees, the less one can live without reservation, so awareness works like a chronic injury.
The state before existence is imagined as a plenitude without desire, self or lack. Longing for that 'no-time' replaces the usual nostalgia for a past golden age. Exile is ontological: we were banished from non-being into being, not from any place within the world.
Doing anything commits one to a world that lucidity has already judged worthless, so action requires a kind of self-deception. Inaction and procrastination are therefore more honest than achievement. Yet the book admits that refusing everything is itself a pose one cannot keep up.
Even without belief, the despairing mind addresses God as the only adequate target for complaint about existence. Mystics and heretics are valued because they took the problem of being all the way to its source. Faith drops away, but the religious intensity of the grievance remains.
