Philippic 2

He knows, then, that they both will pursue their private interests, irrespective of the common advantage of the Greeks. So he thought that if he chose you, he would be choosing friends, and that your friendship would be based on justice; but that if he attached himself to the others, he would find in them the tools of his own ambition. That is why, now as then, he chooses them rather than you. For surely it is not that he regards their fleets as superior to ours, nor that, having discovered some inland empire, he has abandoned the seaboard with its harbors, nor yet that he has a short memory for the speeches and the promises that gained for him the Peace.[*](Had Philip renounced his hope of founding a maritime and commercial state and confined himself to extending his empire north and west of Macedonia, his rejection of Athenian friendship would be intelligible. As it is, it must be otherwise explained.)
