Faith in a holy cause is to a considerable extent a substitute for the lost faith in ourselves.

We can be satisfied with moderate confidence in ourselves and with a moderately good opinion of ourselves, but the faith we have in a holy cause has to be extravagant and uncompromising.

It is characteristic of all movements and crusades that the psychopathic element rises to the top.

Henceforward, I shout to the heavens, I shall deliver no more lectures on behalf of good causes: I am the good cause that denies the need for such lectures. Avaunt, importuning world! Back to my cell.

Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it's the only thing that ever has.

Great causes and little men go ill together.
