It lies on the face of Aristotle's _Politics_, however, that even if the population difficulty had been solved otherwise than by exodus, and even if the Athenians could have guarded against class strife among themselves, the fatality of war in the then civilised world would have sufficed to bring about political dissolution. As he profoundly observes, the training of a people to war ends in their ruin, even when they acquire supremacy, because their legislators have not "taught them how to rest."[116] Add the memorable testimony of Thucydides concerning the deep demoralisation wrought by the Peloponnesian War--a testimony supported by every page of the history of the time. Even the sinister virtue of uniting a people within itself was lacking to the perpetual warfare of the Greeks: the internal hatreds seemed positively to worsen in the atmosphere of the hatreds of the communities. But while the spirit of strife is universal, peoples are inevitably trained to war; and even if the Greek States could have so far risen above their fratricidal jealousies as to form a stable union, it must needs have turned to external conquest, and so run the downward course of the post-Alexandrian Hellenistic Empires, and of the Roman Empire, which in turn sank to dissolution before the assaults of newer militarisms. § 2 Nothing can save any democratic polity from the alternatives of insane strife and imperial subjection but a vital prosperous culture, going hand in hand with a sound economy of industry. The Greek democracies in their different way split on the rock that wrecked the Roman Republic: there was (1) no general mental development commensurate with the political problems which arose for solution, and (2) there was no approach to a sound economics. The first proposition will doubtless be denied by those who, nourished on the literature of Greece, have come to see in its relative excellence, the more confidently because of the abiding difficulty of mastering it, the highest reach of the faculties of thought and expression. But this judgment is fundamentally astray, because of the still subsisting separation, in the literary mind, of the idea of literary merit from the idea of scientific sanity. Men themselves too often vowed to the defence and service of a mythology are slow to see that it was not for nothing that the Athenian people bottomed its culture to the last on myth and superstition. Yet a little reflection might make it clear that the community which forced Socrates to drink the hemlock for an alleged and unproved scepticism, and Anaxagoras to fly for a materialistic hypothesis concerning the sun, could have no political enlightenment adequate to the Athenian needs. We see the superstitious Athenian demos playing the part of the ignorant multitude of all ages, eager for a master, incapable of steadfast self-rule, begging that the magnificent Alcibiades, who led the sacred
