I learned that history is shaped by the use of power, and that different people, leading the same army, with, therefore, approximately the same power, applied it so differently that the army seemed to change from a pack of noble fools at Fredericksburg to panicked cowards melting away at Chancellorsville, then to the grimly determined, stubborn soldiers who held the ridges at Gettysburg, and then, finally, to the disciplined, professional army that ground Lee to dust in Grant's long campaign. It wasn't the soldiers who changed. It was the leader. And even though I could not then have articulated what I understood of military leadership, I knew that I did understand it. I understood, at levels deeper than speech, how a great military leader imposes his will on his enemy, and makes his own army a willing extension of himself.
So one morning, as my Dad drove me to Brigham Young High School along Carterville Road in the heavily wooded bottoms of the Provo River, I wondered: How would you train soldiers for combat in the future? I didn't bother thinking of new land-based weapons systems--what was on my mind, after Foundation, was space. Soldiers and commanders would have to think very differently in space, because the old ideas of up and down simply wouldn't apply anymore. I had read in Nordhoffs and Hall's history of World War I flying that it was very hard at first for new pilots to learn to look above and below them rather than merely to the right and left, to find the enemy approaching them in the air. How much worse, then, would it be to learn to think with no up and down at all?
