"This is what it means to be courageous: to place yourself in the path of irresistible force, certain of your own destruction, for a cause higher than yourself and your petty concerns. Flesh arrayed against bullets, bodies against tanks. Lives willingly offered for beliefs and aspirations. Without sacrifice or the threat of sacrifice, there is no courage.
And bullets and tanks are so much more powerful than flesh and bodies, are they not? But here's the trick: once the credible threat of violence by a government against its own people tips over into the actual use of force, the balance shifts. The government forfeits all legitimacy, and the people assume the mantle of moral and political authority over their own destinies. By sacrificing their blood and their lives, the people themselves can seize power from the men with bullets and machines. For there are always more people than there are bullets or machines."
