History of the Peloponnesian War

So much more have we to fear from this neighbour than from another. Besides, people who, like the Athenians in the present instance, are tempted by pride of strength to attack their neighbours, usually march most confidently against those who keep still, and only defend themselves in their own country, but think twice before they grapple with those who meet them outside their frontier and strike the first blow if opportunity offers.

The Athenians have shown us this themselves; the defeat which we inflicted upon them at Coronea, at the time when our quarrels had allowed them to occupy the country, has given great security to Boeotia until the present day.
