possibility depend frequently on accidents of personal temperament, irritability in a sensual king, wounded sensibilities of pride between two sensitive ladies, there in a moment shone forth a light of hope upon the crusade against war. If _personal_ accidents could, to any serious extent, be amongst the causes of war, then it would become a hopeful duty to combine personal influences that should take an opposite direction. If casual causes could be supposed chiefly to have promoted war, how easy for a nation to arrange permanent and determinate causes against it! The logic of these anecdotes seemed to argue that the whole fountains of war were left to the government of chance and the windiest of levities; that war was not in reality roused into activity by the evil that resides in the human will, but on the contrary, by the simple defect of any will energetic enough or steady enough to merit that name. Multitudes of evils exist in our social system, simply because no steadiness of attention, nor action of combined will, has been converged upon them. War, by the silent evidence of these anecdotes, seemed to lie amongst that class of evils. A new era might be expected to commence in new views upon war; and the evil would be half conquered from the moment that it should be traced to a trivial or a personal origin. All this was plausible, but false. The anecdotes, and all similar anecdotes, might be true, but were delusive. The logical vice in them was--that they substituted an occasion for a cause. The king's ill temper for instance, acting through the levity and impatience of the minister, might be the _causa occasionalis_ of the war, but not its true _causa efficiens_. What _was?_ Where do the true permanent causes of war, as distinguished from its proximate excitements, find their lodgment and abiding ground? They lie in the system of national competitions; in the common political system to which all individual nations are unavoidably parties; in the system of public forces distributed amongst a number of adjacent nations, with no internal principle for adjusting the equilibrium of these forces, and no supreme _Areopagus_, or court of appeal, for deciding disputes. Here lies the _matrix_ of war, because an eternal _matrix_ of disputes lies in a system of interests that are continually the same, and therefore the parents of rivalships too close, that are continually different, and so far the parents of alienation too wide. All war is an instinctive _nisus_ for redressing the errors of equilibrium in the relative position of nations amongst nations. Every nation's duty, first, midst, and last, is to itself. No nation can be safe from continual (because insensible) losses of ground, but by continual jealousies, watchings, and ambitious strivings to mend its own position. Civilities and high-bred courtesies pass and ought to pass between nations; that is the graceful drapery which shrouds their natural, fierce, and tiger-like
