History of the Peloponnesian War

Nor will it be contrary to our habit that we shall address you at some length; but it is the fashion of our country, where few words are sufficient, not to use many; but to use more than ordinary, when there is occasion for proving by words a point of importance to us, and so effecting our purpose.

Receive then what we say, not in a hostile spirit, nor as though you were considered ignorant and were being instructed by us;

but rather regarding it as an admonition to take good advice, offered to men who are well informed. For it is in your power honourably to secure your present good fortune, keeping the advantages you have, and receiving an recession of honour and renown; and not to feel as men do that gain any advantage contrary to their habit; for through hope they are ever grasping for more, because they have unexpectedly enjoyed even their present good luck.
