But in Philip they had already found that common enemy against whom they should have united, if voluntary union was ever again possible among them; and their miserable failure to do so showed plainly that the days of independent States throughout Greece were numbered, and that the first neighbouring power with organization and wealth was certain to pluck the over-ripe fruit of Hellenedom. [Sidenote: Demosthenes another ideal figure in this history.] § 55. This brings us by natural transition to Demosthenes, on whose life and policy it is very necessary to say a few words, seeing that they have been, like so many other topics in Greek history, distorted by the specialists, and made the ground of sentimental rhetoric instead of being sifted with critical care. To utter anything against Demosthenes thirty years ago was almost as bad as to say a word in old Athenian days against the battle of Marathon. This battle was so hymned and lauded by orators and poets that had you suggested its importance in the campaign to be overrated, had you said that you believed the alleged numbers of the Persians to be grossly exaggerated, you would have been set down as an insolent and unpatriotic knave. In the same way the scholars have laid hold of Demosthenes; they have dwelt not only upon the matchless force of his eloquence, but upon the grammatical subtleties of his Greek, till they are so in love with him that whatever is said in his favour is true, and whatever appears to be against him is false. As I have not spent the whole of a long life either in commenting on this great author or in vindicating for him all the virtues under heaven, I may perhaps be better able than greater scholars to give a fair estimate of his political merits. [Sidenote: He sees the importance of a foreign policy for Athens] [Sidenote: against Persia] [Sidenote: or Macedonia.] Demosthenes at the outset of his career saw plainly, like Isocrates, that a foreign policy was necessary to give not only dignity, but consistency, to the counsels of Athens; and he too at the outset, misconceiving the real power of Philip, thought that Persia was the serious foe[134:1], and should be the object of most importance to Athenian politicians. Darius Ochus, the last vigorous king of Persia, had made such military preparations for the reconquest of his rebellious provinces as to alarm all the Asiatic Greeks and conjure up the phantom of a new Persian war. But presently the real danger set aside this bugbear; the activity and military skill of Philip, added to his discovery or utilization of the Thracian gold mines, made him clearly the future lord of the Hellenes if he could prevent them from combining against him for a few years.
