Rules for Revolution?

Someone sent me a ridiculous booklet by David Horowitz which is meant to demean either Barack Obama or Saul Alinsky (or both). The latter of whom once wrote:

One of the most important things in life is what Judge Learned Hand described as 'that ever-gnawing inner doubt as to whether you're right.' If you don't have that, if you think you've got an inside track to absolute truth, you become doctrinaire, humorless and intellectually constipated.

Makes sense to me.
