History of the Peloponnesian War

If we go to war, and call in to help us a people that are ready enough to carry their arms even where they are not invited; and if we injure ourselves at our own expense, and at the same time serve as the pioneers of their dominion, we may expect when they see us worn out, that they will one day come with a larger armament, and seek to bring all of us into subjection.

And yet as sensible men, if we call in allies and court danger, it should be in order to enrich our different countries with new acquisitions, and not to ruin what they possess already; and we should understand that the intestine discords which are so fatal to communities generally, will be equally so to Sicily, if we, its inhabitants, absorbed in our local quarrels, neglect the common enemy.

These considerations should reconcile individual with individual, and city with city, and unite us in a common effort to save the whole of Sicily. Nor should any one imagine that the Dorians only are enemies of Athens, while the Chalcidian race is secured by its Ionian blood;

the attack in question is not inspired by hatred of one of two nationalities, but by a desire for the good things in Sicily, the common property of us all.
