History of the Peloponnesian War

"And yet we ought, if we are wise, to aim at acquiring for our own respective countries what does not belong to them, rather than at diminishing what they already have, both in calling in allies and incurring fresh dangers; and to consider that faction is most ruinous to states, and particularly to Sicily, the inhabitants of which are all being plotted against, while we are at variance city with city.

Knowing this then, we ought to make peace, individual with individual, and state with state, and to make a common effort to save the whole of Sicily: and the thought should be entertained by no one, that though the Dorian part of us are enemies of the Athenians, the Chalcidian race is secured by its Ionian connexion.

For they are not attacking our nations, because they are different, and from their hatred of one of them; but from coveting the good things of Sicily, which we possess in common. And this they have now shown upon the invitation of the Chalcidian race:

for to those who had never yet assisted them on the ground of their alliance, they themselves with forwardness answered their claim, beyond the letter of the compact. And very excusable is it that the Athenians should practise this covetousness and forecasting;

and I blame not those who wish to reign, but those who are too ready to be subject. For human nature is always disposed to rule those that submit, but to guard against those that attack. And if any of us know this, but do not forecast as we ought, and if any one has come here without regarding it as his first care, that all should make a good arrangement for what is a general cause of alarm;

we are mistaken in our views. Most speedily then should we be rid of that alarm by making peace with each other:

for it is not from their own country that the Athenians set out against us, but from that of those who invited them here. And in this way war is not terminated by war, but our quarrels are ended without trouble by peace; and those who have been called in, having come with specious injustice, will go back with reasonable want of success.
