So that I cannot imagine what ground Theopompus had to say that Demosthenes was of a fickle, unsettled disposition, and could not long continue firm either to the same men or the same affairs; whereas the contrary is most apparent, for the same party and post in politics which he held from the beginning, to these he kept constant to the end; and was so far from leaving them while he lived that he chose rather to forsake his life than his purpose. He was never heard to apologize for shifting sides like Demades, who would say he often spoke against himself, but never against the city; nor as Melanopus, who being generally against Callistratus, but being often bribed off with money, was wont to tell the people, "The man indeed is my enemy, but we must submit for the good of our country;" nor again as Nicodemus, the Messenian, who having first appeared on Cassander's side, and afterwards taken part with Demetrius, said the two things were not in themselves contrary, it being always most advisable to obey the conqueror. We have nothing of this kind to say against Demosthenes, as one who would turn aside or prevaricate, either in word or deed. There could not have been less variation in his public acts if they had all been played, so to say, from first to last, from the same score. Panaetius, the philosopher, said that most of his orations are so written as if they were to prove this one conclusion, that what is honest and virtuous is for itself only 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 honourable before their own safety and preservation. So that if he had kept his hands clean, if his courage for the wars had been answerable to the generosity of his principles, and the dignity of his orations, he might deservedly have his name placed, not in the number of such orators as Moerocles, Polyeuctus, and Hyperides, but in the highest rank with Cimon, Thucydides, and Pericles.
Certainly amongst those who were contemporary with him, Phocion, though he appeared on the less commendable side in the commonwealth, and was counted as one of the Macedonian party, nevertheless, by his courage and his honesty, procured himself a name not inferior to these of Ephialtes, Aristides, and Cimon. But Demosthenes, being neither fit to be relied on for courage in arms, as Demetrius says, nor on all sides inaccessible to bribery (for how invincible soever he was against the gifts of Philip and the Macedonians, yet elsewhere he lay open to assault, and was overpowered by the gold which came down from Susa and Ecbatana), was therefore esteemed better able to recommend than to imitate the virtues of past times. And yet (excepting only Phocion), even in his life and manners, he far surpassed 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 counsellor, whether you will or no, O ye men of Athens, you shall always have me; but a sycophant or false accuser, though you would have me, 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, amongst other misdemeanours, 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.
The oration which Apollodorus made use of, and by it carried the cause against Timotheus, the general, in an action of debt, it is said was written for him by Demosthenes; as also those against Phormion and Stephanus, in which latter case he was thought to have acted dishonourably, for the speech which Phormion used against Apollodorus was also of his ******; he, as it were, having simply furnished two adversaries out of the same shop with weapons to wound one another. Of his orations addressed to the public assemblies, that against Androtion and those against Timocrates and Aristocrates, were written for others, before he had come forward himself as a politician. They were composed, it seems, when he was but seven or eight and twenty years old. That against Aristogiton, and that for the Immunities, he spoke himself, at the request, as he says, of Ctesippus, the son of Chabrias, but, as some say, out of courtship to the young man's mother. Though, in fact, he did not marry her, for his wife was a woman of Samos, as Demetrius, the Magnesian, writes, in his book on Persons of the same Name. It is not certain whether his oration against Aeschines, for Misconduct as Ambassador, was ever spoken; although Idomeneus says that Aeschines wanted only thirty voices to condemn him. But this seems not to be correct, at least so far as may be conjectured from both their orations concerning the Crown; for in these, neither of them speaks clearly or directly of it, as a cause that ever came to trial. But let others decide this controversy.
