It is impossible, men of Athens, impossible to gain permanent power by injustice, perjury, and falsehood. Once in a way and for a brief season such things endure, and fed with hopes make, it may be, a brave show of blossom, but at the last they are detected and fall to pieces. For a house, I take it, or a ship or anything of that sort must have its chief strength in its substructure; and so too in affairs of state the principles and the foundations must be truth and justice. There is no vestige of these today in the power that Philip has built up.
I urge you strongly to send help to Olynthus, and the best and quickest method that anyone can suggest will please me most. To the Thessalians you must send an embassy to inform some of them of our intentions and to stir up the others; for they have already decided to demand the restoration of Pagasae and to protest against the occupation of Magnesia.
But you must make sure, men of Athens, that our envoys do not confine themselves to words; they must be able to give some practical proof that we have taken the field in a way worthy of our city and that we are really grappling with the situation. All words, apart from action, seem vain and idle, especially words from Athenian lips; for the greater our reputation for a ready tongue, the greater the distrust it inspires in all men.
