Stockdale on Stoicism 1

Let's go right to the old master, Clausewitz. He said: "War is an act of violence to compel the enemy to do your will." Your will, not his will. We are in the business of breaking people's wills. That's all there is to war; once you have done that, the war is over.

And what is the most important weapon in breaking people's wills? This may surprise you, but I am convinced that holding the moral high ground is more important than firepower. 

For Clausewitz, war was not an activity governed by scientific laws, but a clash of wills, of moral forces. He wrote: "It is not the loss in men, horses, or guns, but in order, courage, confidence, cohesion and plan which come into consideration whether the engagement can still be continued; it is principally the moral forces which decide here." 

Moral forces! Conviction! Mind games!
