The evil of militarism is not that it shows certain men to be fierce and haughty and excessively warlike. The evil of militarism is that it shows most men to be tame and timid and excessively peaceable. The professional soldier gains more and more power as the general courage of a community declines. Thus the Pretorian guard became more and more important in Rome as Rome became more and more luxurious and feeble. The military man gains the civil power in proportion as the civilian loses the military virtues. And as it was in ancient Rome so it is in contemporary Europe. There never was a time when nations were more militarist. There never was a time when men were less brave. All ages and all epics have sung of arms and the man; but we have effected simultaneously the deterioration of the man and the fantastic perfection of the arms. Militarism demonstrated the decadence of Rome, and it demonstrates the decadence of Prussia.
G.K. Chesterton, Heretics, 1905
