for the base from which the Athenians propose to move is not their own territory, but that of the people who asked them to intervene. And if we follow this course, war will not end in another war, but without trouble quarrels will end quietly in peace, and those who have been invited to intervene, having come with a fair pretext for injustice, will depart home with a fair plea for failure.
"So far, then, as the Athenians are concerned, this is the great advantage we win if we are well advised;
but as to the question of peace, which all men agree is a most desirable thing, why should we not make it here among ourselves? Or, think you, if one person now enjoys a blessing and another labours under adversity, it is not tranquillity far more than war that will put an end to the latter and perpetuate the former? And has not peace its honours and less hazardous splendours, and all the other advantages on which one might dilate as easily as on the horrors of war? Considering these things, you should not overlook my advice, but should rather look forward each to his own salvation thereby. And if any of you cherishes the confident belief that he can gain anything either by insisting on his rights or by an appeal to force, let him not, through the baffling of his hopes, suffer a grievous disappointment;
for he knows that many men ere now, whether pursuing with vengeance those who have wronged them, or in other cases, hoping to gain some advantage by the exercise of power, have, on the one hand, not only not avenged themselves but have not even come out whole, and, on the other hand, instead of gaining more, have sacrificed what was their own.
