History of the Peloponnesian War

Let us reflect also, that if we were severally engaged in [only] quarrels with our equals about boundaries of territory, it might be borne : but as it is, the Athenians are a match for us all together, and still more powerful against single states; so that unless all in a body, and nation by nation, and city by city, with one mind we defend ourselves against them, they will certainly subdue us without trouble, when divided. And as for defeat, though it may be a terrible thing for any one to hear of, let him know that it brings nothing else but downright slavery:

which is disgraceful for the Peloponnese to be even mentioned as contingent, and for so many cities to be ill-treated by one. In that case we should appear either to be justly treated, or to put up with it through cowardice, and to show ourselves inferior to our fathers, who liberated Greece; whereas we do not even secure this liberty for ourselves, but allow a tyrant state to set itself up amongst us, though we think it right to put down monarchs in any one state.
