History of the Peloponnesian War

For if they enter, they will take all our several states into their own possession by force. So much more dangerous is the neighbourhood of the Athenians than of other people. And such as upon confidence in their strength invade their neighbours, as the Athenians now do, use to be bold in warring on those that sit still, defending themselves only in their own territories; whereas they be less urgent to those that are ready to meet them without their own limits, or [also] to begin the war when opportunity serveth.

We have experience hereof in these same men. For after we had overcome them at Coroneia, at what time through our own sedition they held our country in subjection, we established a great security in Boeotia, which lasted till this present.
