ideal. The nature of this ideal is of slight importance; whether it be the cult of Rome, the might of Athens, or the triumph of Allah, it will suffice to endow all the individuals of the race that is forming with perfect unity of sentiment and thought.
At this stage a new civilisation, with its institutions, its beliefs, and its arts, may be born. In pursuit of its ideal, the race will acquire in succession the qualities necessary to give it splendour, vigour, and grandeur. At times no doubt it will still be a crowd, but henceforth, beneath the mobile and changing characteristics of crowds, is found a solid substratum, the genius of the race which confines within narrow limits the transformations of a nation and overrules the play of chance.
After having exerted its creative action, time begins that work of destruction from which neither gods nor men escape. Having reached a certain level of strength and complexity a civilisation ceases to grow, and having ceased to grow it is condemned to a speedy decline. The hour of its old age has struck.
