History of the Peloponnesian War

But we are not now come to declare to an audience familiar with them the misdeeds of a state so open to accusation as is the Athenian, but much rather to blame ourselves, who, with the warnings we possess in the Hellenes in those parts that have been enslaved through not supporting each other, and seeing the same sophisms being now tried upon ourselves—such as restorations of Leontine kinsfolk and support of Egestaean allies—do not stand together and resolutely show them that here are no Ionians, or Hellespontines, or islanders, who change continually, but always serve a master, sometimes the Mede and sometimes some other, but free Dorians from independent Peloponnese, dwelling in Sicily.

Or, are we waiting until we be taken in detail, one city after another; knowing as we do that in no other way can we be conquered, and seeing that they turn to this plan, so as to divide some of us by words, to draw some by the bait of an alliance into open war with each other, and to ruin others by such flattery as different circumstances may render acceptable? And do we fancy when destruction first overtakes a distant fellow-countryman that the danger will not come to each of us also, or that he who suffers before us will suffer in himself alone?
