We may, perhaps, attribute it to the extreme position taken up with regard to military service by the Quakers and Mennonites that the example of Descartes had so slight a following. That thick phalanx of our kind who fondly mistake their own mental timidity for moderation, perpetually make use of the doctrines of extremists as an excuse for tolerating or even defending what in the abstract they admit to be evil; and it was unfortunately with this moderate party that Grotius elected to throw in his lot. No one admitted more strongly the evils of war. The reason he himself gave for writing his ‘De Jure Pacis et Belli’ was the licence he saw prevailing throughout Christendom in resorting to hostilities; recourse had to arms for slight motives or for none; and when war was once begun an utter rejection of all reverence for divine or human law, just as if the unrestrained commission of every crime became thenceforth legitimate. Yet, instead of throwing the weight of his judgment into the scale of opinion which opposed the custom altogether (though he did advocate an international tribunal that should decide differences and compel obedience to its decisions), he only tried to shackle it with rules of decency that are absolutely foreign to it, with the result, after all, that he did very little to humanise wars, and nothing to make them less frequent. Nevertheless, though Grotius admitted the abstract lawfulness of military service, he made it conditional on a thorough conviction of the righteousness of the cause at issue. This is the great and permanent merit of his work, and it is here that we touch on the pivot or central question of military ethics. The orthodox theory is, that with the cause of war a soldier has no concern, and that since the matter in contention is always too complicated for him to judge of its merits, his only duty is to blindfold his reason and conscience, and rush whithersoever his services are commanded. Perhaps the best exposition of this simple military philosophy is that given by Shakespeare in his scene of the eve of Agincourt, where Henry V., in disguise, converses with some soldiers of the English army. ‘Methinks,’ says the king, ‘I could not die anywhere so contented as in the king’s company, his cause being just and his quarrel honourable.’ _William._ ‘That’s more than we know.’ _Bates._ ‘Ay, or more than we should seek after, for we know enough if we know we are the king’s subjects. If his cause be wrong, our obedience to the king wipes the crime of it out of us.’
