Philippic 3

For he says that he is not at war, but for my part, so far from admitting that in acting thus he is not observing the peace with you, I assert that when he lays hands on Megara, sets up tyrannies in Euboea, makes his way, as now, into Thrace, hatches plots in the Peloponnese, and carries out all operations with his armed force, he is breaking the peace and making war upon you—unless you are prepared to say that men who bring up the siege-engines are keeping the peace until they actually bring them to bear on the walls. But you will not admit that; for he who makes and devises the means by which I may be captured is at war with me, even though he has not yet hurled a javelin or shot a bolt.

In what then consists your danger, if anything should happen? In the alienation of the Hellespont, in the control of Megara and Euboea by one who is at war with you, and in the defection of the Peloponnesians to his side. Am I still to say that the man who brings this siege-engine to bear on your city is at peace with you?

So far from saying that, I date his hostility from the very day when he wiped out the Phocians. I say that you will be wise if you defend yourselves now, but if you let the opportunity pass, you will not be able to act even when you desire to. I so far dissent, Athenians, from all you counsellors that I do not think you ought to trouble yourselves now about the Chersonese or Byzantium.

Help them, if you will, guard them from harm supply the troops already there with all that they require, but let your deliberations embrace all the Greek states and the great danger that besets them. But I wish to tell you the grounds for my alarm about our condition, so that if my reasoning is sound, you may adopt it as your own and take forethought for yourselves, even if you refuse to take it for the others also; but if I seem to you a driveler and a dotard, neither now nor at any other time pay any heed to me as if I were in my senses.
