It is true that the ruinousness of war under modern conditions is apparent to all. But this gives no sufficient guarantee that war will not break forth suddenly, even in opposition to the wishes of those who take part in it. Involuntarily we call to mind the words of the great Bacon, that "in the vanity of the world a greater field of action is open for folly than for reason, and frivolity always enjoys more influence than judgment." War, it would appear from an analysis of the history of mankind, has in the past been a normal attribute of human life. The position now has changed in much, but still the new continues to contend with the old. With the innumerable voices which are now bound up in our public opinion, and the many different representatives of its interests, naturally appear very different views on militarism and its object--war. The propertied classes are inclined to confuse even the intellectual movement against militarism with aspirations for the subversion of social order; on the other hand, agitators, seeking influence on the minds of the masses, deny all existing rights, and promise to the masses more than the most perfect institutions could give them. And although the masses are slow to surrender themselves to abstract reasoning, and act usually only under the influence of passion, there can be no doubt that this agitation penetrates the people more and more deeply. With such a position of affairs, it is necessary that influential and educated men should seriously attempt to give themselves a clear account of the effect of war under modern conditions; whether it will be possible to realise the aims of war, and whether the extermination of millions of men will not be wholly without result. If, after consideration of all circumstances, we answer ourselves: "War with such conditions is impossible; armies could not sustain those cataclysms which a future war would call forth; the civil population could not bear the famine and interruption of industry"; then we might ask the general question: "Why do the peoples more and more exhaust their strength in accumulating means of destruction which are valueless even to accomplish the ends for which they are prepared?" In recent times war has become even more terrible than before in consequence of perfected weapons of destruction and systems of equipment and training utterly unknown in the past. Infantry and artillery fire will have unprecedented force; smoke will no longer conceal from the survivors the terrible consequences of the battle. From this, and from the fact that the mass of soldiers will have but recently been called from the field, the factory, and the workshop, it will appear that even the psychical conditions of war have changed.
