History of the Peloponnesian War

This would just be the case with the Athenians at present. They are now attacking us in the belief that we shall not resist, having a right to judge us severely because we did not help the Lacedaemonians in crushing them; but if they were to see us showing a courage for which they are not prepared, they would be more dismayed by the surprise than they could ever be by our actual power.

I could wish to persuade you to show this courage; but if this cannot be, at all events lose not a moment in preparing generally for the war; and remember all of you that contempt for an assailant is best shown by bravery in action, but that for the present the best course is to accept the preparations which fear inspires as giving the surest promise of safety, and to act as if the danger was real. That the Athenians are coming to attack us, and are already upon the voyage, and all but here—this is what I am sure of.’
