His first entering into public business was about the time of the Phocian war. But the object which he chose for himself in the commonwealth was noble and just, the defence of the Greek against Philip; and in this he behaved himself so worthily that he soon grew famous, and excited attention everywhere for his eloquence and courage in speaking. He was admired through all Greece, the king of Persia courted him, and by Philip himself he was more esteemed than all the other orators. His very enemies were forced to confess that they had to do with a man of mark; for such a character even Aeschines and Hyperides give him, where they accuse and speak against him. Demosthenes would never turn aside or prevaricate, either in word or deed. Panaetius, the philosopher, said, that most of his orations were written, as if they were to prove this one conclusion: that only what is honest and virtuous is to be chosen; as that of the Crown, that against Aristocrates, that for the Immunities, and the Philippics; in all which he persuades his fellow-citizens to pursue not that which seems most pleasant, easy, or profitable; but declares over and over again, that they ought in the first place to prefer that which is just and honorable, before their own safety and preservation. Excepting only Phocion, he far surpassed, even in his life and manners, the other orators of his time. None of them addressed the people so boldly; he attacked the faults, and opposed himself to the unreasonable desires of the multitude, as may be seen in his orations. Theopompus writes, that the Athenians having by name selected Demosthenes, and called upon him to accuse a certain person, he refused to do it; upon which the assembly being all in an uproar, he rose up and said, "Your counselor, whether you will or no, O ye men of Athens, you shall always have me; but a sycophant or false accuser, I shall never be." And his conduct in the case of Antiphon was perfectly aristocratical; whom, after he had been acquitted in the assembly, he took and brought before the court of Areopagus, and, setting at naught the displeasure of the people, convicted him there of having promised Philip to burn the arsenal; whereupon the man was condemned by that court, and suffered for it. He accused, also, Theoris, the priestess, among other misdemeanors, of having instructed and taught the slaves to deceive and cheat their masters, for which the sentence of death was passed upon her, and she was executed.
