XIII. I cannot, therefore, understand what Theopompus meant by saying that he was of an inconstant disposition, and not able to remain long associated with any party or any line of policy. It appears rather that he remained throughout the consistent advocate of the same principles, and a member of the same political party to which he originally belonged, and that he not only never changed his politics in his life, but even lost his life because he would not change them. He was not like Demades, who to excuse himself for changing sides pleaded that he had oftentimes gone against his own words, but never against the interests of the state. Still less can he be compared with Melanopus, the political opponent of Kallistratus, who was often bribed by him to allow some measure to pass, and on these occasions would say to the people, "The man is my personal enemy, but I postpone my personal feelings to the good of my country." Nikodemus of Messene, who first took up with Kassander, and afterwards became the advocate of Demetrius, used to declare that he never was inconsistent, because it was always best to obey the strongest party. But in the case of Demosthenes, unlike these men, we can say that he never deviated either in word or deed from the one direct line of policy which he unswervingly pursued to the end. The philosopher Panætius declares that in most of his orations, as in that about the Crown, that against Aristokrates, that on behalf of the persons exempted from taxation (against Leptines), and in the Philippics, we can trace the principle that honour ought to be pursued for its own sake; for in all these he urges his countrymen not to adopt the most pleasant, the most easy, or the most profitable line of policy, but often thinks that caution and even safety should be regarded as of less importance than honourable conduct; so that if to his noble principles and high-minded eloquence he had joined warlike courage and clean hands from bribery, he would have been worthy to rank, not with Moerokles, Polyeuktus, and Hypereides, but with Kimon, Thucydides, Perikles, and other great men of old.
