History of the Peloponnesian War

Let them now therefore be punished as their crime requires, and do not, while you condemn the aristocracy, absolve the people. This is certain, that all attacked you without distinction, although they might have come over to us, and been now again in possession of their city. But no, they thought it safer to throw in their lot with the aristocracy and so joined their rebellion!

Consider therefore! if you subject to the same punishment the ally who is forced to rebel by the enemy, and him who does so by his own free choice, which of them, think you, is there that will not rebel upon the slightest pretext; when the reward of success is freedom, and the penalty of failure nothing so very terrible?

We meanwhile shall have to risk our money and our lives against one state after another; and if successful, shall receive a ruined town from which we can no longer draw the revenue upon which our strength depends; while if unsuccessful, we shall have an enemy the more upon our hands, and shall spend the time that might be employed in combating our existing foes in warring with our own allies.

No hope, therefore, that rhetoric may instil or money purchase, of the mercy due to human infirmity must be held out to the Mitylenians. Their offence was not involuntary, but of malice and deliberate; and mercy is only for unwilling offenders.

I therefore now as before persist against your reversing your first decision, or giving way to the three failings most fatal to empire—pity, sentiment, and indulgence.

Compassion is due to those who can reciprocate the feeling, not to those who will never pity us in return, but are our natural and necessary foes: the orators who charm us with sentiment may find other less important arenas for their talents, in the place of one where the city pays a heavy penalty for a momentary pleasure, themselves receiving fine acknowledgments for their fine phrases; while indulgence should be shown towards those who will be our friends in future, instead of towards men who will remain just what they were, and as much our enemies as before.
