If they march against our country we will sail against theirs, and it will then be found that the desolation of the whole of Attica is not the same as that of even a fraction of Peloponnese; for they will not be able to supply the deficiency except by a battle, while we have plenty of land both on the islands and the continent.
The rule of the sea is indeed a great matter. Consider for a moment. Suppose that we were islanders: can you conceive a more impregnable position? Well, this in future should, as far as possible, be our conception of our position. Dismissing all thought of our land and houses, we must vigilantly guard the sea and the city. No irritation that we may feel for the former must provoke us to a battle with the numerical superiority of the Peloponnesians. A victory would only be succeeded by another battle against the same superiority: a reverse involves the loss of our allies, the source of our strength, who will not remain quiet a day after we become unable to march against them. We must cry not over the loss of houses and land but of men's lives; since houses and land do not gain men, but men them. And if I had thought that I could persuade you, I would have bid you go out and lay them waste with your own hands, and show the Peloponnesians that this at any rate will not make you submit.
I have many other reasons to hope for a favorable issue, if you can consent not to combine schemes of fresh conquest with the conduct of the war, and will abstain from willfully involving yourselves in other dangers; indeed, I am more afraid of our own blunders than of the enemy's devices.
But these matters shall be explained in another speech, as events require; for the present dismiss these men with the answer that we allow Megara the use of our market and harbours, when the Lacedaemonians suspend their alien acts in favour of us and our allies, there being nothing in the treaty to prevent either one or the other: that we will leave the cities independent, if independent we found them when we made the treaty, and when the Lacedaemonians grant to their cities an independence not involving subservience to Lacedaemonian interest, but such as each severally may desire: that we are willing to give the legal satisfaction which our agreements specify, and that we shall not commence hostilities, but shall resist those who do commence them. This is an answer agreeable at once to the rights and the dignity of Athens.
