Nor was this all, but he also made his conversation with people abroad, his common speech, and his business, subservient to his studies, taking from hence occasions and arguments as matter to work upon. For as soon as he was parted from his company, down he would go at once into his study, and run over everything in order that had passed, and the reasons that might be alleged for and against it. Any speeches, also, that he was present at, he would go over again with himself, and reduce into periods; and whatever others spoke to him, or he to them, he would correct, transform, and vary in several ways. Hence it was, that he was looked upon as a person of no great natural genius, but one who owed all the power and ability he had in speaking to labor and industry. He was very rarely heard to speak off-hand, but though he were by name frequently called upon by the people, as he sat in the assembly, yet he would not rise unless he had previously considered the subject, and come prepared for it. So that many of the popular pleaders used to make it a jest against him; and Pytheas once, scoffing at him, said that his arguments smelt of the lamp. To which Demosthenes gave the sharp answer, "It is true, indeed, Pytheas, that your lamp and mine are not conscious of the same things." To others, however, he would not deny it, but would admit frankly enough, that he neither entirely wrote his speeches beforehand, nor yet spoke wholly extempore. And he would affirm, that it was the more truly popular act to use premeditation, such preparation being a kind of respect to the people.
How then, some may say, was it, that Aeschines speaks of him as a person much to be wondered at for his boldness in speaking? And, when Lamachus, the Myrinaean, had written a panegyric upon king Philip and Alexander, in which he uttered many things in reproach of the Thebans and Olynthians, and at the Olympic Games recited it publicly, Demosthenes, then rising up, and recounting historically and demonstratively what benefits and advantages all Greece had received from the Thebans and Chalcidians, and on the contrary, what mischiefs the flatterers of the Macedonians had brought upon it, so turned the minds of all that were present that the sophist, in alarm at the outcry against him, secretly made his way out of the assembly. But Demosthenes, it would seem, regarded the reserve and sustained manner of Pericles, and his forbearing to speak on the sudden, or upon every occasion, as being the things to which he principally owed his greatness, and this he followed, and endeavored to imitate, neither wholly neglecting the glory which present occasion offered, nor yet willing too often to expose his faculty to the mercy of chance. For, in fact, the orations which were spoken by him had much more of boldness and confidence in them than those that he wrote. Eratosthenes says that often in his speaking he would be transported into a kind of ecstasy, and Demetrius, that he uttered the famous metrical adjuration to the people,
By the earth, the springs, the rivers, and the streams,
as a man inspired, and beside himself. One of the comedians calls him a rhopoperperethras—a loud declaimer about petty matters; from rhopos, small wares, and perperos, a loud talker; and another scoffs at him for the use of antithesis:—
And what he took, took back; a phrase to please
The very fancy of Demosthenes.
Unless, indeed, this also is meant by Antiphanes for a jest upon the speech on Halonesus, which Demosthenes advised the Athenians not to take at Philip's hands, but to take back.
All, however, used to consider Demades, in the mere use of his natural gifts, an orator impossible to surpass, and that in what he spoke on the sudden, he excelled all the study and preparation of Demosthenes. And Ariston, the Chian, has recorded a judgment which Theophrastus passed upon the orators; for being asked what kind of orator he accounted Demosthenes, he answered, "Worthy of the city of Athens;" and then, what he thought of Demades, he answered, "Above it." And the same philosopher reports, that Polyeuctus, the Sphettian, one of the Athenian politicians about that time, was wont to say that Demosthenes was the greatest orator, but Phocion the ablest, as he expressed the most sense in the fewest words. And, indeed, it is related, that Demosthenes himself, as often as Phocion stood up to plead against him, would say to his acquaintance, "Here comes the knife to my speech." Yet it does not appear whether he had this feeling for his powers of speaking, or for his life and character, and meant to say that one word or nod from a man who was really trusted, would go further than a thousand lengthy periods from others.
Demetrius, the Phalerian, tells us, that he was informed by Demosthenes himself, when old, that the ways he made use of to remedy his natural bodily infirmities and defects were such as these: his inarticulate and stammering pronunciation he overcame and rendered more distinct by speaking with pebbles in his mouth; his voice he disciplined by declaiming and reciting speeches or verses when he was out of breath, while running or going up steep places; and that in his house he had a large looking-glass, before which he would stand and go through his exercises. It is told that some one once came to request his assistance as a pleader, and related how he had been assaulted and beaten. "I am sure," said Demosthenes, "nothing of the kind can have happened to you." Upon which the other, raising his voice, exclaimed loudly, "What, Demosthenes, nothing has been done to me?" "Ah," replied Demosthenes, "now I hear the voice of one that has been injured and beaten." Of so great consequence towards the gaining of belief did he esteem the tone and action of the speaker. When a thief, who had the nickname of the Brazen, was attempting to upbraid him for sitting up late, and writing by candlelight, "I know very well," said he, "that you had rather have all lights out; and wonder not, O ye men of Athens, at the many robberies which are committed, since we have thieves of brass and walls of clay."
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.
