Went into the city to see Control last Saturday. It begins with Ian brooding:

Existence well what does it matter?
I exist on the best terms I can.
The past is now part of my future,
The present is well out of hand.

P. 100, Joy Division, Ian Curtis, Lisbon, Assirio e Alvim, 1983.

This bilingual edition includes in the back part VII of Plato's Republic; the bit about the cave.  ¶ 5:50 AM
