Everything is very simple in War, but the simplest thing is difficult. - Carl von Clausewitz

A resolução é a coragem aplicada a um caso particular; se se torna uma marca do caráter, passa a ser um hábito do espírito. Não se trata aqui da coragem diante do perigo físico, mas da coragem perante as responsabilidades, ou seja, de certa maneira, perante o perigo moral. É aquilo a que muitas vezes se chamou a coragem do espírito, porque dimana do espírito, ainda que não seja, no entanto, um esforço do espírito, mas sim do temperamento. A inteligência pura e simples não forja a coragem, pois as pessoas mais inteligentes são na sua maioria desprovidas de espírito de resolução. A inteligência precisa, primeiramente, despertar o sentimento de coragem, que mantém e sustenta, porque, nos momentos cruciais, o homem obedece mais aos seus sentimentos que às suas ideias.

As we admire presence of mind in a pithy answer to anything said unexpectedly, so we admire it in a ready expedient on sudden danger. Neither the answer nor the expedient need be in themselves extraordinary, if they only hit the point; for that which as the result of mature reflection would be nothing unusual, therefore insignificant in its impression on us, may as an instantaneous act of the mind produce a pleasing impression. The expression “presence of mind” certainly denotes very fitly the readiness and rapidity of the help rendered by the mind.

Whether this noble quality of a man is to be ascribed more to the peculiarity of his mind or to the equanimity of his feelings, depends on the nature of the case, although neither of the two can be entirely wanting. A telling repartee bespeaks rather a ready wit, a ready expedient on sudden danger implies more particularly a well-balanced mind.

(1) War becomes a completely isolated act, which arises suddenly, and is in no way connected with the previous history of the combatant States. (2) If it is limited to a single solution, or to several simultaneous solutions. (3) If it contains within itself the solution perfect and complete, free from any reaction upon it, through a calculation beforehand of the political situation which will follow from it.
