History of the Peloponnesian War

There is no disgrace in connections giving way to one another, a Dorian to a Dorian, or a Chalcidian to his brethren; above and beyond this we are neighbors, live in the same country, are girt by the same sea, and go by the same name of Sicilians. We shall go to war again, I suppose, when the time comes, and again make peace among ourselves by means of future congresses;

but the foreign invader, if we are wise, will always find us united against him, since the hurt of one is the danger of all; and we shall never, in future, invite into the island either allies or mediators.
