A great thing, in truth, is the control of the sea. Just consider: if we were islanders, who would be more unassailable ? So, even now, we must, as near as may be, imagine ourselves such and relinquish our land and houses, but keep watch over the sea and the city; and we must not give way to resentment against the Peloponnesians on account of our losses and risk a decisive battle with them, far superior in numbers as they are. If we win we shall have to fight them again in undiminished number, and if we fail, our allies, the source of our strength, are lost to us as well; for they will not keep quiet when we are no longer able to proceed in arms against them. And we must not make lament for the loss of houses and land, but for men; for these things do not procure us men, but men these. Indeed, had I thought that I should persuade you, I should have urged you to go forth and lay them waste yourselves, and thus show the Peloponnesians that you will not, for the sake of such things, yield them obedience.
" Many other considerations also lead me to hope that we shall prove superior, if you will consent not to attempt to extend your empire while you are at war and not to burden yourselves needlessly with dangers of your own choosing; for I am more afraid of our own mistakes than of the enemy's plans.
But these matters will be explained to you on some later occasion when we are actually at war; at the present time let us send the envoys back with this answer: As to the Megarians, that we will permit them to use our markets and harbours, if the Lacedaemonians on their part will cease passing laws for the expulsion of aliens so far as concerns us or our allies (for nothing in the treaty forbids either our action or theirs; as to the states in our confederacy, that we will give them their independence if they were independent when we made the treaty, and as soon as they on their part grant the states in their alliance the right to exercise independence in a manner that conforms, not to the interest of the Lacedaemonians, but to the wishes of the individual states; and as to arbitration, that we are willing to submit to it in accordance with the treaty, and will not begin war, but will defend ourselves against those who do.
This answer is just and at the same time consistent with the dignity of the city. But we must realise that war is inevitable, and that the more willing we show ourselves to accept it, the less eager will our enemies be to attack us, and also that it is from the greatest dangers that the greatest honours accrue to a state as well as to an individual.
