If we were to adopt the method by which Aristotle endeavoured to arrive at a correct conception of the nature of a State, and review the part which war has played in world-history, and, disregarding the mechanical enumeration of causes and effects, if we were to examine the motives, impulses, or ideals embodied in the great conflicts of world-history, the question whether war be a necessary evil, an infliction to which humanity must resign itself, would be seen to emerge in another shape—whether war be an evil at all; whether in the life-history of a State it be not an attestation of the self-devotion of that State to the supreme end of its being, even of its power of consecration to the Highest Good?

Every great war known to history resolves itself ultimately into the conflict of two ideals. The Cavalier fights in triumph or defeat in a cause not less exalted than that of the Puritan, and Salamis acquires a profounder significance when considered, not from the standpoint of Athens and Themistocles merely, but from the camp of Xerxes, and the ruins of the mighty designs of Cyrus and Hystaspes, an incident which Aeschylus found tragic enough to form a theme for one of his loftiest trilogies.[[1]] The wars against Pisa and Venice light with intermittent gleams the else sordid annals of Genoa; and through the grandeur and ferocity of a century of war Rome moves to world-empire, and Carthage to a death which throws a lustre over her history, making its least details memorable, investing its merchants with an interest beyond that of princes, and bequeathing to mankind the names of Hamilcar and Hannibal as a strong argument of man's greatness if all other records were to perish. Qui habet tenam habet bellum is but a half-truth. No war was ever waged for material ends only. Territory is a trophy of battle, but the origin of war is rooted in the character, the political genius, the imagination of the race. One of the profoundest of modern investigators in mediaeval history, Dr. Georg Waitz, insists on the attachment of the Teutonic kindred to the soil, and on the measures by which in the primitive constitutions the war-instinct was checked.[[2]] The observation of Waitz is just, but a change in environment develops the latent qualities of a race. The restless and melancholy surge, the wide and desolate expanse of the North Sea exalted the imagination of the Viking as the desert the imagination of the Arab. Not the cry of "New lands" merely, but the adventurous heart of his race, lured on by the magic of the sea, its receding horizons, its danger and its change, spread the fame and the terror of the Norsemen from the basilicas, the marbles, and the thronging palaces of Byzantium to the solitary homestead set in the English forest-clearing, or in the wastes of Ireland which the zeal of her monasteries was slowly reclaiming. To the glamour of war for its own sake the Crusades brought the transforming power of a new ideal. The cry "Deus vult!" at Clermont marks for the whole Teutonic race the final transition from the type of Alaric and Chlodovech, of Cerdic and Hrolf, to that of Godfrey and Tancred, Richard Lion-heart and Saint Louis, from the sagas and the war-songs of the northern skalds to the chivalrous verse of the troubadours, a Bertrand or a Rudel, to the epic narrative of the crusades which transfigures at moments the prose of William of Tyre or of Orderic, of Geoffrey de Vinsauf or of Joinville.

The wide acceptance of the territorial theory of the origin of war as an explanation of war, and the enumeration by historians of causes and results in territory or taxation, can be ascribed only to that indolence of the human mind, the subtle inertia which, as Tacitus affirms, lies in wait to mar all high endeavour—"Subit quippe etiam ipsius inertiae dulcedo, et invisa primo desidia postremo amatur."

The wars of the Hebrews, if territorial in their apparent origin, reveal in their course their true origin in the heart of the race, the consciousness of the high destiny reserved for it amongst the Semitic kindred, amongst the nations of the earth. If ever there were a race which seemed destined to found a world-empire by the sword it is the Hebrew. They make war with Roman relentlessness and with more than Roman ideality, the Lord God of Hosts guiding their march or their retreat by day and by night ceaselessly. Every battle is a Lake Regillus, and for the great Twin Brethren it is Jehovah Sabaoth that nerves the right arm of his faithful. The forms of Gideon and Joshua, though on a narrower stage, have a place with those other captains of their race—Hannibal, Bar-Cochab, Khalid, Amr, Saad,[[3]] and Mothanna. The very spirit of war seems to shape their poetry from the first chant for the defeat of Egypt to that last song of constancy in overthrow, of unconquerable resolve and sure vengeance, a march music befitting Judas Maccabaeus and his men, beside which all other war-songs, even the "Marseillaise," appear of no account—the Al Naharoth Babel—"Let my sword-hand forget, if I forget thee, O Jerusalem"—passing from the mood of pity through words that are like the flash of spears to a rapture of revenge known only to the injured spirits of the great when baulked of their God-appointed fate. Yet on the shores of the Western Sea the career of this race abruptly ends, as if in Palestine they found a Capua, as the Crusaders long afterwards, Templars and Hospitallers, found in that languid air, the Syrian clime, a Capua. Thus the Hebrews missed the world-empire which the Arabs gained, but even out of their despair created another empire, the empire of thought; and the power to found this empire, whether expressed in the character of their warriors, or in that unparalleled conviction which marks the Hebrew in the remotest lands and most distant centuries, the certainty of his return, the refusal, unyielding, to believe that he has missed the great meed which, there in Palestine, there in the Capua of his race, seemed within his grasp, but attests further that it is in no lust for territory that these wars originate.

In the historical and speculative literature of Hellas and Rome war occupies a position essentially identical with that which it occupies in the Hebrew. It is the assertion of right by violence, or it is the pursuit of a fate-appointed end. Aristotle, with his inveterate habit of subjecting all things—art, statesmanship, poetry—to ethics, regards war as a valuable discipline to the State, a protection against the enervating influence of peace. As the life of the individual is divided between business and leisure, so, according to Aristotle, the life of the State is divided between war and peace. But to greatness in peace, greatness in war is a primal condition. The State which cannot quit itself greatly in war will achieve nothing great in peace. "The slave," he bitterly remarks, "knows no leisure, and the State which sets peace above war is in the condition of a slave." Aristotle does not mean that the slave is perpetually at work, or that war is the sole duty of a great State, but as the soul destined to slavery is incapable even in leisure of the contemplations of the soul destined to freedom, so to the nation which shrinks from war the greatness that belongs to peace can never come. Courage, Plato defines as "the knowledge of the things that a man should fear and that he should not fear," and in a state, a city, or an empire courage consists in the unfaltering pursuit of its being's end against all odds, when once that end is manifest. This ideal element, this formative principle, underlies the Hellenic conception of war throughout its history, from its first glorification in Achilles to the last combats of the Achaean League—from the divine beauty of the youthful Achilles, dazzling as the lightning and like the lightning pitiless, yet redeemed to pathos by the certainty of the quick doom that awaits him, on to the last bright forms which fall at Leuctra, Mantinea, and Ipsus. It requires a steadfast gaze not to turn aside revolted from the destroying fury of Greeks against Greeks—Athens, Thebes, Sparta, Corinth, and Macedon—and yet even their claim to live, their greatness, did in this consist, that for so light yet so immortal a cause they were content to resign the sweet air and the sight of the sun, and of this wondrous fabric of a world in which their presence, theirs, the children of Hellas, was the divinest wonder of all.

Of the grandeur and elevation which Rome imparted to war and to man's nature it is superfluous to speak. As in statesmanship, so in war, he who would greatly praise another describes his excellence as Roman, and thinks that all is said. The silver eagle which Caius Marius gave as an ensign to the legions is for once in history the fit emblem of the race that bore it to victory and world-dominion. History by fate or chance added a touch of the supernatural to the action of Marius. The silver eagle announced the empire of the Caesars; the substitution of the Labarum by Constantine heralded its decline. With the emblem of humiliation and peace, the might of Rome sinks, yet throughout the centuries that follow, returns of galvanic life, recollections of its ancient valour—as in Stilicho, Belisarius, Heraclius, and Zimisces[[4]]—bear far into the Middle Age the dread name of the Roman legion, though the circuit of the eagle's flight, once wide as the ambient air, is then narrowed to a league or two on either side of the Bosphorus.

§ 2. DEFINITION OF WAR

To push the survey further would but add to the instances, without deepening the impression, of the measureless power of the ideal element in war, alike in the history of the great races of the past and of the present. Even the wars which seem most arbitrary and, to the judgment of their contemporaries, purposeless, acquire, upon a deeper scrutiny and in after ages, a profound enough significance. Behind the immediate occasion, trivial or capricious, sordid or grandiose, the destiny of the race, like the Nemesis of Greek Tragedy, advancing relentlessly, pursuing its own far-off and lofty ends, constantly reveals itself.

War, therefore, I would define as a phase in the life-effort of the State towards completer self-realization, a phase of the eternal nisus, the perpetual omnipresent strife of all being towards self-fulfilment. Destruction is not its aim, but the intensification of the life, whether of the conquering or of the conquered State. War is thus a manifestation of the world-spirit in the form the most sublime and awful that can enthrall the contemplation of man. It is an action radiating from the same source as the heroisms, the essential agonies, +agôníai+, conflicts, of all life. "In this theatre of a world," as Calderon avers, "all are actors, todos son representantes." There too the State enacts its tragedy. Nation, city, or empire, it too is a representante. Though the stage is of more imposing dimensions, the Force of which each wears the mask is one with the Force which sets the stars their path and guides the soul of man to its appointed goal. A war then is in the development of the consciousness of the State analogous to those moments in the individual career when, in Hamlet's phrase, his fate "crying out," death is preferable to a disregard of the Summoner. The state, the nation, or the empire hazards death, is content to resign existence itself, if so be it fulfil but its destiny, and swerve not from its being's law. Not to be envied is that man who, in the solemn prayer of two embattled hosts, can discern but an organized hypocrisy, a mockery, an insult to God! God is the God of all the earth, but dark are the ways, obscure and tangled the forest-paths, in which He makes His children walk. A mockery? That cry for guidance in the dread ordeal, that prayer by the hosts, which is but the formulated utterance of the still, the unwhispered prayer in the heart of each man on the tented field—"Through death to life, even through death to life, as my country fares on its great path through the thickening shadows to the greater light, to the higher freedom!"—is this a mockery? Yet such is the prayer of armies. War so considered ceases to be an action continually to be deplored, regretted, or forgiven, ceases to be the offspring of human weakness or human crime, and the sentence of the Greek orator recovers its living and consoling power—"Of the dead who have fallen in battle the wide earth itself is the sepulchre; their tomb is not the grave in which they are laid, but the undying memory of the generations that come after them. They perish, snatched in a moment, in the height of achievement, not from their fear, but from their renown. Fortunate! And you who have lost them, you, who as mortal have been born subject unto disaster, how fortunate are you to whom sorrow comes in so glorious a shape!"

Thus the great part which war has played in human history, in art, in poetry, is not, as Rousseau maintains, an arraignment of the human heart, not necessarily the blazon of human depravity, but a testimony to man's limitless capacity for devotion to other ends than existence for existence' sake—his pursuit of an ideal, perpetually.
