History of the Peloponnesian War

‘Fellow allies, we can no longer accuse the Lacedaemonians of having failed in their duty: they have not only voted for war themselves, but have assembled us here for that purpose. We say their duty, for supremacy has its duties. Besides equitably administering private interests, leaders are required to show a special care for the common welfare in return for the special honors accorded to them by all in other ways.

For ourselves, all who have already had dealings with the Athenians require no warning to be on their guard against them. The states more inland and out of the highway of communication should understand that if they omit to support the coast powers, the result will be to injure the transit of their produce for exportation and the reception in exchange of their imports from the sea; and they must not be careless judges of what is now said, as if it had nothing to do with them, but must expect that the sacrifice of the powers on the coast will one day be followed by the extension of the danger to the interior, and must recognize that their own interests are deeply involved in this discussion.

For these reasons they should not hesitate to exchange peace for war. If wise men remain quiet, while they are not injured, brave men abandon peace for war when they are injured, returning to an understanding on a favorable opportunity: in fact, they are neither intoxicated by their success in war, nor disposed to take an injury for the sake of the delightful tranquillity of peace.

Indeed, to falter for the sake of such delights is, if you remain inactive, the quickest way of losing the sweets of repose to which you cling; while to conceive extravagant pretensions from success in war is to forget how hollow is the confidence by which you are elated.

For if many ill-conceived plans have succeeded through the still greater fatuity of an opponent, many more, apparently well laid, have on the contrary ended in disgrace. The confidence with which we form our schemes is never completely justified in their execution; speculation is carried on in safety, but, when it comes to action, fear causes failure.
