History of the Peloponnesian War

"Thus it appears that we come for our parts with arguments of equity and right, whereas the proceedings of these other are nothing else but violence and rapine. And now we shall show you likewise that you cannot receive them in point of justice.

For although it be in the articles that the cities written with neither of the parties may come in to whether of them they please, yet it holds not for such as do so to the detriment of either, but only for those that, having revolted from neither part, want protection and bring not a war with them instead of peace to those (if they be wise) that receive them.

For you shall not only be auxiliaries unto these but to us, instead of confederates, enemies. For if you go with them, it follows they must defend themselves not without you.
