History of the Peloponnesian War

To describe their character in a word, one might truly say that they were born into the world to take no rest themselves and to give none to others.

Such is Athens, your antagonist. And yet, Lacedaemonians, you still delay, and fail to see that peace stays longest with those, who are not more careful to use their power justly than to show their determination not to submit to injustice. On the contrary, your ideal of fair dealing is based on the principle that if you do not injure others, you need not risk your own fortunes in preventing others from injuring you.

Now you could scarcely have succeeded in such a policy even with a neighbor like yourselves; but in the present instance, as we have just shown, your habits are old-fashioned as compared with theirs.

It is the law as in art, so in politics, that improvements ever prevail; and though fixed usages may be best for undisturbed communities, constant necessities of action must be accompanied by the constant improvement of methods. Thus it happens that the vast experience of Athens has carried her further than you on the path of innovation.

Here, at least, let your procrastination end. For the present, assist your allies and Potidaea in particular, as you promised, by a speedy invasion of Attica, and do not sacrifice friends and kindred to their bitterest enemies, and drive the rest of us in despair to some other alliance.
