History of the Peloponnesian War

And this has at present been your case, Athenians, with reference to the Lacedaemonians and their allies; from having, contrary to your expectation, gained the advantage over them, (comparing your present position with the fears you at first entertained,) you have despised them, and are now desiring the conquest of Sicily.

You ought not, however, to be elated through the misfortunes of your adversaries, but then only to feel confident when you have mastered their spirits; nor should you think that the Lacedaemonians are doing ought but considering, in consequence of their disgrace, in what way they may even now, if possible, overthrow us, and bring their own discredit to a happy termination; especially as they have studied a reputation for bravery, as a thing of the greatest importance, and for the greatest length of time.

So that our great struggle will be, if we are wise, not for the Segestans in Sicily, men who are barbarians, but that we may vigorously guard against a state which is plotting against us [*]( Or, as Arnold renders it, in the way of oligarchy; i. e. threatening as, not with the loss of our conquests, but with a change of government.) by the spread of oligarchical principles.
