Triumph Of Will
...Grant went off to his first war. Offandedly, he gives us what I take to be the key if not to his character to his success: "One of my superstitions had always been when I started to go any where, or to do anything, not to turn back, or stop until the thing intended was accomplished." This defines not only a certain sort of military genius but explains field-commander Grant who would throw wave after wave of troops into battle, counting on superior numbers to shatter the enemy while himself ignoring losses.
-- Gore Vidal, The Grants, Sept. 18, 1975
107. A sign of strong character, when once the resolution has been taken, to shut the ear even to the best counter-arguments. Occasionally, therefore, a will to stupidity.
-- Nietzsche, BG&E
