"If you don't admire something, if you don't love it, you have no reason
to write a word about it. Spinoza or Nietzsche are philosophers whose
critical and destructive powers are without equal, but this power always
springs from affirmation, from joy, from a cult of affirmation and joy,
from the exigency of life against those who would mutilate and mortify
life. For me, that is philosophy itself." (Deleuze)
