Accepting then the fact--for such I believe it to be--that the law of nations is the law of force, let us waste no time in lamentations. In the first place they are useless; and in the second they seem to me highly presumptuous; for what are we, or what is our knowledge, that we should aspire to correct the course of this world's governance? Let us rather consider what is meant by the word _force_, as an element in the conflict of communities. Force, in the human creature, is of two kinds, moral and physical; and in war, as Napoleon himself said, the moral is to the physical as four to one. What is this moral force? It is an indefinable consciousness of superiority. And whence does it arise? I must summon a poet to help me with my answer. "Self-reverence, self-knowledge, self-control, These three alone lead life to sovereign power." Self-reverence, which can be based only upon high aspirations and high ideals; self-knowledge, which combines the courage to face facts, the patience to accept them, the constancy to turn them to good account; self-control, the offspring of self-denial and self-discipline. We are too much inclined to think of war as a matter of combats, demanding above all things physical courage. It is really a matter of fasting and thirsting; of toiling and waking; of lacking and enduring; which demands above all things moral courage. Yet let us hasten to add that, without bodily soundness and strength to resist privation, hardship and fatigue, an army is naught. And here we strike the peculiarity which makes war the true touch-stone of nations. It is the supreme test of their merits and demerits both moral and physical. By a community's art, literature, science and philosophy you may take the measure of its intellectual attainments; through its administrative institutions and laws you may form some judgment of its political intelligence; from the bodily structure and condition of its citizens you may form conclusions as to its physical fitness; but of the general soundness of the body politic, of the capacity of its leaders, of the devotion of their followers, of the moral force which inspires all ages and both sexes to endure hardship and sorrow with cheerfulness, and to meet adversity with confidence unshaken and with courage undaunted--for all this the trial of all trials is war.
