War is the domain of physical exertion and suffering.
The political object is the goal, war is the means of reaching it, and the means can never be considered in isolation form their purposes.
War is not an exercise of the will directed at an inanimate matter.

War is regarded as nothing but the continuation of state policy with other means.
War is the province of danger.

War is not merely a political act but a real political instrument, a continuation of political intercourse, a carrying out of the same by other means.

Two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to truth and second, the courage to follow this faint light wherever it may lead.
