able points, Nicolai shows that in earlier days apologists for war were exceptional. Even among the epic poets of war, those whose song was of heroism, the direct references to war convey fear and disapproval. Delight in war (Kriegslust), love of war for its own sake, is peculiar to modern literature. We have to come down to the writings of Moltke, Steinmetz, Lasson, Bernhardi, and Roosevelt, to find apotheoses of war, pæans of war whose jubilation is quasi-religious. Nor was it until the outbreak of the present struggle that such huge armies as those of to-day were witnessed. The Greek armies in classical antiquity did not exceed 20,000. Those of imperial Rome, ranged from 100,000 to 200,000. In the eighteenth century, armies of 150,000 were known; while Napoleon had an army of 750,000. In 1870, there were armies of two and a half millions. But in the present war there are ten million fighting men in each camp (Chapter Five and Chapter Six). The increase is colossal, and quite recent. Even if we take into account the possibility of a struggle in the near future between Europeans and Mongols, a proportional increase could not continue beyond a generation or two, for the whole population of the globe would not suffice to furnish such armies.
But Nicolai is not appalled by the titanic dimensions of the monster he is fighting. Indeed, this very fact gives him confidence in the ultimate victory of his cause. For biology has revealed to him the mysterious law of giganthanasia. One of the most important principles of paleontology teaches that all animals (with the exception of insects, which, for this very reason, are, with the brachiopods, the oldest families on the globe), all species, tend throughout the centuries to grow larger and larger until, of a sudden, when they seem greatest and strongest, their forms disappear from the geological record. In nature it is always the large forms that die. That which is large must die for the reason that, in conformity with the imperious law of growth, the day comes when it exceeds the limits of its primordial possibilities. Thus is it, writes Nicolai, with war. Along the boundless field-grey battle
