History of the Peloponnesian War

"If they object injustice in that you receive their colony, henceforth let them learn that all colonies so long as they receive no wrong from their mother city, so long they honour her; but when they suffer injury from her, they then become alienate; for they are not sent out to be the slaves of them that stay, but to be their equals.

That they have done us the injury is manifest; for when we offered them a judicial trial of the controversy touching Epidamnus, they chose to prosecute their quarrel rather by arms than judgment.

Now let that which they have done unto us, who are their kindred, serve you for some argument not to be seduced by their demands and made their instruments before you be aware. For he lives most secure that hath fewest benefits bestowed upon him by his enemies to repent of.
