For the love of gain would reconcile the weaker to the dominion of the stronger, and the possession of capital enabled the more powerful to reduce the smaller towns to subjection. And it was at a somewhat later stage of this development that they went on the expedition against Troy.

Difficulty of subsistence made the invaders reduce the numbers of the army to a point at which it might live on the country during the prosecution of the war.

Love of power, operating through greed and through personal ambition, was the cause of all these evils. To this must be added the violent fanaticism which came into play once the struggle had broken out. Leaders of parties in the cities had programmes which appeared admirable – on one side political equality for the masses, on the other the safe and sound government of the aristocracy – but in professing to serve the public interest they were seeking to win the prizes for themselves. In their struggles for ascendancy nothing was barred; terrible indeed were the actions to which they committed themselves, and in taking revenge they went farther still. Here they were deterred neither by the claims of justice nor by the interests of the state; their one standard was the pleasure of their own party at that particular moment, and so, either by means of condemning their enemies on an illegal vote or by violently usurping power over them, they were always ready to satisfy the hatreds of the hour. Thus neither side had any use for conscientious motives; more interest was shown in those who could produce attractive arguments to justify some disgraceful action. As for the citizens who held moderate views, they were destroyed by both the extreme parties, either for not taking part in the struggle or in envy at the possibility that they might survive.
