History of the Peloponnesian War

"On many other occasions before this have I been convinced that a democracy is incapable of maintaining dominion over others, and I am so more than ever from your present change of purpose respecting the Mytilenaeans.

For owing to your daily freedom from fear, and from plotting against each other, you entertain the same views towards your allies also. And you do not reflect, in whatever case you may either have made a mistake through being persuaded by their words, or may have given way to pity, that you show such weakness to your own peril, and at the same time too gain no gratitude from your allies; not considering that it is a tyrannical dominion which you hold, and over men who are plotting against you, and involuntarily subject to you;

and who obey you not from any favours you confer on them to your own hurt, but from the fact of your being superior to them through your power, rather than their good feeling. But of all things is the most fearful if nothing of what we have resolved stedfast; and if we are not convince that a state with inferior laws which are unchanged is better than one with good ones which are not authoritative; the homely wit with moderation is more useful than cleverness with intemperance;

So then rivals to do, and not to advise your people contrary to our real opinion, urged on by cleverness and rivalry of talent.
