The enemy of humanism is not faith; the enemy of humanism is hate, is fear, is ignorance, is the darker part of man that is in every humanist, every person, in the world. That is the thing we have to fight. Faith is something we have to embrace. Faith in God is believing absolutely in something with no proof whatsoever. Faith in humanity means believing absolutely in something with a huge amount of proof to the contrary.
Joss Whedon
faith, humanism
