I just wanted to share the following quotation. One of my professors has it as his e-mail signature:

"The more our daily life appears standardized, stereotyped, submitted to the accelerated reproduction of consumer goods, the more art must become part of life and rescue from it that small difference which operates between levels of repetition ... so that, in the end, Difference can express itself ... even if it's only in the form of a contradiction here or there, thereby liberating the forces needed to destroy this world."

-- Gilles Deleuze, Répétition et différence

Hm. I like that.
