The ideas of the past, although half destroyed, being still very powerful, and the ideas which are to replace them being still in process of formation, the modern age represents a period of transition and anarchy. It is not easy to say as yet what will one day be evolved from this necessarily somewhat chaotic period. What will be the fundamental ideas on which the societies that are to succeed our own will be built up? We do not at present know. Still it is already clear that on whatever lines the societies of the future are organised, they will have to count with a new power, with the last surviving sovereign force of modern times, the power of crowds. On the ruins of so many ideas formerly considered beyond discussion, and to-day decayed or decaying, of so many sources of authority that successive revolutions have destroyed, this power, which alone has arisen in their stead, seems soon destined to absorb the others. While all our ancient beliefs are tottering and disappearing, while the old pillars of society are giving way one by one, the power of the crowd is the only force that nothing menaces, and of which the prestige is continually on the increase. The age we are about to enter will in truth be the ERA OF CROWDS. Scarcely a century ago the traditional policy of European states and the rivalries of sovereigns were the principal factors that shaped events. The opinion of the masses scarcely counted, and most frequently indeed did not count at all. To-day it is the traditions which used to obtain in politics, and the individual tendencies and rivalries of rulers which do not count; while, on the contrary, the voice of the masses has become preponderant. It is this voice that dictates their conduct to kings, whose endeavour is to take note of its utterances. The destinies of nations are elaborated at present in the heart of the masses, and no longer in the councils of princes.
