History of the Peloponnesian War

Thus was wickedness on foot in every kind throughout all Greece by the occasion of their sedition. Sincerity (whereof there is much in a generous nature) was laughed down; and it was far the best course to stand diffidently against each other with their thoughts in battle array, which no speech was so powerful nor oath terrible enough to disband.

And being all of them the more they considered the more desperate of assurance, they rather contrived how to avoid a mischief than were able to rely on any man's faith.

And for the most part, such as had the least wit had the best success; for both their own defect and the subtlety of their adversaries putting them into a great fear to be overcome in words, or at least in preinsidiation, by their enemies' great craft, they therefore went roundly to work with them with deeds.

Whereas the other, not caring though they were perceived and thinking they needed not to take by force what they might do by plot, were thereby unprovided and so the more easily slain.

In Corcyra then were these evils for the most part committed first; and so were all other, which either such men as have been governed with pride rather than modesty by those on whom they take revenge were like to commit in taking it; or which such men as stand upon their delivery from long poverty out of covetousness, chiefly to have their neighbours' goods would contrary to justice give their voices to; or which men, not for covetousness but assailing each other on equal terms, carried away with the unruliness of their anger would cruelly and inexorably execute.
