History of the Peloponnesian War

If any man here envieth or also feareth us (for the strongest are still liable unto both), and would therefore wish that the Syracusians might be weakened to make them more modest, but not vanquished for their own safety's sake, that man hath conceived a hope beyond the power of man. For it is not reasonable that the same man should be the disposer both of his desires and of his fortune.

And if his aim should fail him, he might, deploring his own misery, peradventure wish to enjoy my prosperity again. But this will not be possible to him that shall abandon me and not undertake the same dangers, though not in title, yet in effect the same that I do. For though it be our power in title, yet in effect it is your own safety you defend.

And you men of Camarina, that are borderers and likely to have the second place of danger, you should most of all have foreseen this and not have aided us so dully. You should rather have come to us; and that which, if the Athenians had come first against Camarina, you should in your need have implored at our hands, the same you should now also have been seen equally to hearten us withal to keep us from yielding. But as yet, neither you nor any of the rest have been so forward.
