History of the Peloponnesian War

"It is but fair, citizens of Athens, that those who, without any previous claim on the score of important service rendered or of an existing alliance, come to their neighbours to ask aid, as we do now, should show in the first place, if possible, that what they ask is advantageous, or at least that it is not hurtful, and, in the second place, that their gratitude can be depended on; but in case they establish neither of these things clearly, they should not be angry if unsuccessful.

Now the Corcyraeans have sent us to ask for an alliance, and in full confidence that they will be able to give you guarantees on just these points.

But it so happens that our policy has been at one and the same time inconsistent, as it must seem to you, with our petition, and is also disadvantageous under present circumstances to ourselves;

for although heretofore we have freely chosen to be allies of no one, we have now come to ask others for an alliance, and at the same time, in the face of the present war with the Corinthians, we are, because of this very policy, isolated. And so what was formerly fondly imagined to be wise discretion on our part—to enter into no foreign alliance, with the possibility of having to take our share of the danger of our neighbour's policy—has now, in the event, proved want of wisdom and a source of weakness.
