Perpetual Peace: A Philosophical Essay

In tribes and clans, and had begun to call

These meadows and that range of hills his own,

The tasted sweets of property begat

Desire of more; .........

...............

Thus wars began on earth. These fought for spoil,

And those in self-defence. Savage at first

The onset, and irregular. At length

One eminent above the rest, for strength,

For stratagem, or courage, or for all,

Was chosen leader. Him they served in war,

And him in peace for sake of warlike deeds

Rev’renced no less.........

Thus kings were first invented.”

[6] “Among uncivilised nations, there is but one profession honourable, that of arms. All the ingenuity and vigour of the human mind are exerted in acquiring military skill or address.” Cf. Robertson’s History of Charles V., (Works, 1813, vol. V.) Sect. I. vii.

[7] Similarly we find that the original meaning of the Latin word “hostis” was “a stranger.”

[8] In Aristotle we find the high-water mark of Greek thinking on this subject. “The object of military training,” says he, (Politics, Bk. IV. Ch. XIV., Welldon’s translation—in older editions Bk. VII.) “should be not to enslave persons who do not deserve slavery, but firstly to secure ourselves against becoming the slaves of others; secondly, to seek imperial power not with a view to a universal despotic authority, but for the benefit of the subjects whom we rule, and thirdly, to exercise despotic power over those who are deserving to be slaves. That the legislator should rather make it his object so to order his legislation upon military and other matters as to promote leisure and peace is a theory borne out by the facts of history.” ... (loc. cit. Ch. XV.). “War, as we have remarked several times, has its end in peace.”

Aristotle strongly condemns the Lacedæmonians and Cretans for regarding war and conquest as the sole ends to which all law and education should be directed. Also in non-Greek tribes like the Scythians, Persians, Thracians and Celts he says, only military power is admired by the people and encouraged by the state. “There was formerly too a law in Macedonia that any one who had never slain an enemy should wear the halter about his neck.” Among the Iberians too, a military people, “it is the custom to set around the tomb of a deceased warrior a number of obelisks corresponding to the number of enemies he has killed.... Yet ... it may well appear to be a startling paradox that it should be the function of a Statesman to succeed in devising the means of rule and mastery over neighbouring peoples whether with or against their own will. How can such action be worthy of a statesman or legislator, when it has not even the sanction of law?” (op. cit., IV. Ch. 2.)

We see that Aristotle disapproves of a glorification of war for its own sake, and regards it as justifiable only in certain circumstances. Methods of warfare adopted and proved in the East would not have been possible in Greece. An act of treachery, for example, such as that of Jael, (Judges IV. 17) which was extolled in songs of praise by the Jews, (loc. cit. V. 24) the Greek people would have been inclined to repudiate. The stories of Roman history, the behaviour of Fabricius, for instance, or Regulus and the honourable conduct of prisoners on various occasions released on parole, show that this consciousness of certain principles of honour in warfare was still more highly developed in Rome.

Socrates in the Republic (V. 469, 470) gives expression to a feeling which was gradually gaining ground in Greece, that war between Hellenic tribes was much more serious than war between Greeks and barbarians. In such civil warfare, he considered, the defeated ought not to be reduced to slavery, nor the slain despoiled, nor Hellenic territory devastated. For any difference between Greek and Greek is to “be regarded by them as discord only—a quarrel among friends, which is not to be called war”.... “Our citizens [i.e. in the ideal republic] should thus deal with their Hellenic enemies; and with barbarians as the Hellenes now deal with one another.” (V. 471.)

The views of Plato and Aristotle on this and other questions were in advance of the custom and practice of their time.

[9] “The Lord is a man of war,” said Moses (Exodus XV. 3). Cf. Psalms XXIV. 8. He is “mighty in battle.”

[10] This was bound up with the very essence of Islam; the devout Mussulman could suffer the existence of no unbeliever. Tolerance or indifference was an attitude which his faith made impossible. “When ye encounter the unbelievers,” quoth the prophet (Koran, ch. 47), “strike off their heads, until ye have made a great slaughter among them.... Verily if God pleased he could take vengeance on them without your assistance; but he commandeth you to fight his battles.”

The propagation of the faith by the sword was not only commanded by the Mohammedan religion: it was that religion itself.

[11] See Acts X. 28:—“Ye know that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation.”

[12] Neither, however, is there any which regards the soldier as a murderer.

[13] In the early centuries of our era Christians seem to have occasionally refused to serve in the army from religious scruples. But soldiers were not always required to change their profession after baptism. And in Acts X., for example, nothing is said to indicate that the centurion, Cornelius, would have to leave the Roman army. See Tertullian: De Corona (Anti-Nicene Christian Library), p. 348.

[14] There were so-called “Sacred Wars” in Greece, but these were due mainly to disputes caused by the Amphictyonic League. They were not religious, in the sense in which we apply the epithet to the Thirty Years’ war.

[15] “The administration of justice among rude illiterate people, was not so accurate, or decisive, or uniform, as to induce men to submit implicitly to its determinations. Every offended baron buckled on his armour, and sought redress at the head of his vassals. His adversary met him in like hostile array. Neither of them appealed to impotent laws which could afford them no protection. Neither of them would submit points, in which their honour and their passions were warmly interested, to the slow determination of a judicial inquiry. Both trusted to their swords for the decision of the contest.” Robertson’s History of Charles V., (Works, vol. V.) Sect. I., p. 38.

[16] Erasmus in the “Ἰχθυοφαγία” (Colloquies, Bailey’s ed., Vol. II., pp. 55, 56) puts forward the suggestion that a general peace might be obtained in the Christian world, if the Emperor would remit something of his right and the Pope some part of his.

[17] Cf. Robertson, op. cit., Sect. III., p. 106, seq.

[18] Robertson (op. cit., Note XXI., p. 483) quotes the following statement: “flamma, ferro, caede, possessiones ecclesiarum praelati defendebant.” (Guido Abbas ap. Du Cange, p. 179.)

[19] J. A. Farrar, in a pamphlet, (reprinted from the Gentleman’s Magazine, vol. 257, 1884) on War and Christianity, quotes the following passage from Wycliffe in which he protests against this blot upon the Church and Christian professions.—“Friars now say that bishops can fight best of all men, and that it falleth most properly to them, since they are lords of all this world. They say Christ bade His disciples sell their coats, and buy them swords; but whereto, if not to fight? Thus friars make a great array, and stir up many men to fight. But Christ taught not His apostles to fight with a sword of iron, but with the sword of God’s Word, and which standeth in meekness of heart and in the prudence of man’s tongue.... If man-slaying in others be odious to God, much more in priests, who should be vicars of Christ.” See also the passage where Erasmus points out that King David was not permitted to build a temple to God, because he was a man of blood. “Nolo clericos ullo sanguine contaminari. Gravis impietas!” (Opera, IX., 370 B.)

This question had already been considered by Thomas Aquinas, who decided that the clergy ought not to be allowed to fight, because the practices of warfare, although right and meritorious in themselves, were not in accordance with a holy calling. (Summa, II. 2: Qu. 40.)

Aquinas held that war—excluding private war—is justifiable in a just cause. So too did Luther, (cf. his pamphlet: Ob Kriegsleute auch in seligem Stande sein können?) Calvin and Zwingli, the last of whom died sword in hand.

With regard to the question of a fighting clergy, the passage quoted from Origen (pp. 14, 15, above) has considerable interest, Origen looks upon the active participation of priests in warfare as something which everyone would admit to be impossible.

[20] See also the Querela Pacis, 630 B., (Opera, IV.):—“Whosoever preaches Christ, preaches peace.” Erasmus even goes the length of saying that the most iniquitous peace is better than the most just war (op. cit., 636 C).

[21] Cf. Robertson, op. cit., Note XXI. p. 483 and Sect. I., p. 39.

[22] It is uncertain in what year the De Jure Belli of Gentilis was published—a work to which Grotius acknowledges considerable indebtedness. Whewell, in the preface to his translation of Grotius, gives the date 1598, but some writers suppose it to have been ten years earlier.
