"When we open our eyes then we know. And when we know then we have to act. That is the cycle of activism. We open our eyes and we act, but then we need to doubt that our actions ever made a difference in the first place. Because when we don't doubt, we become self-righteous and our actions haven't made a difference. So open your eyes, act, doubt, open them again, act, doubt."
-- paraphrased from Bill Ayers talk on the "Progress of Change" at Northwestern University on 2/4/09.
