Digressioni sui fenomeni di confine in Husserl

The essay clarifies the Husserlian concept of boundary by interpreting it as a passage (Übergang) between different states and levels of consciousness. With particular attention to Husserl's late research manuscripts, the author investigates the meaning of biological birth and death, dreamless sleep and original wakefulness, and the concept of the unconscious itself, looking for their relation to different senses of temporality.
