History of the Peloponnesian War

For they are come to Sicily on the pretext, indeed, which you hear, but with the purpose which we all suspect; and, in my opinion, they are wishing, not to restore the Leontines to their home, but to eject us from ours. For surely it is not consistent that they should depopulate the cities in Greece, but re-settle those in Sicily; and that they should care for the Leontines, who are Chalcidians, because of their connexion with them, but keep in slavery the Chalcidians in Euboea, from whom these are a colony.

But the method is the same, by which they both gained possession of those places, and are attempting to do so with these. For after they had been appointed leaders, by the free choice both of the Ionians and of all who were of Athenian origin, for the purpose of talking vengeance on the Mede; by charging some of them with failure in military service, others with mutual hostilities, and others on any specious plea which they severally had to urge, they reduced them to subjection.

And so they did not withstand the Mede for the sake of liberty—neither these men for that of the Greeks, nor the Greeks for their own—but the former did it to enslave the Greeks to themselves, instead of to the Mede; the latter, to get a new master, one not more unwise, but more wise for evil.

"But, open as the Athenian state is to accusation, we are not come at the present time to prove before those who know this already, in how many respects it is committing injustice; but much rather to censure ourselves, because, with the warnings given us by the Greeks in those quarters, how they were enslaved through not assisting one another, and with the same sophisms being now practised on ourselves— their re-instatements of their Leontine kinsmen, and succours to their Segestan allies—we will not unite together, and show them that the people here are no Ionians, or Hellespontines and islanders, who are always passing to a new master, either the Mede or some one else, and still kept in slavery, but free Dorians from the independent Peloponnese now living in Sicily.
