ATH. “As to pleas of justice, they think that neither the one nor the other lacks them, but that those who preserve their freedom owe it to their power, and that we do not attack them because we are afraid. So that, to say nothing of our enlarging our empire, you would afford us security by being subdued, especially if you, an insular power, and weaker than other islanders, should fail to show yourselves superior to a power which is master of the sea.”
MEL. “But do you not think there is security in the other course?[*](i. e. in neutrality, referred to in ch. xciv.) For here also it is necessary, just as you force us to abandon all pleas of justice and seek to persuade us to give ear to what is to your own interests, that we, too, tell you what is to our advantage and try to persuade you to adopt it, if that happens to be to your advantage also. How, we say, shall you not make enemies of all who are now neutral, as soon as they look at our case and conclude that some day you will come against them also? And in this what else are you doing but strengthening the enemies you already have, and bringing upon you, against their inclination, others who would never have thought of becoming your enemies?”
