"The struggle with the shadow is the only real struggle. When the visual sensation confronts the invisible force that conditions it, it releases a force that is capable of vanquishing the invisible force or even befriending it. Life screams at death, but death is no longer this all-too-visible thing that makes us faint; it is this invisible force that life detects, flushes out, and makes visible through the scream" 

- Gilles Deleuze
