It results from his whole conception of his art,
16
and it is implied in his method of teaching, that Isokrates aimed at the production of work which should have a lasting value. This is a fourth characteristic which distinguishes him strongly from the mass of his profession, and, in a certain degree, even from its better members. Since the end of the fifth century B. C. a literature of political pamphlets had been coming into existence; writing was now recognised as a mode of influencing public opinion on the affairs of the day. Thrasymachos pleaded for the Larisaeans, as Isokrates for the Plataeans, in a rhetorical pamphlet; in the same way Isokrates attacked, and Alkidamas defended, the new Messene

. Now to Isokrates belongs the credit of trying to raise the dignity and worth of this intermittent journalism. He aimed at making his essays on contemporary events something more than telling
pamphlets; he wished them to have a lasting value both literary and political, answering to the conscientious labour and thought which had been spent upon them. The ambition which he set steadily before his school is not simply that of rising above the forensic eloquence which triumphs for a day; it is that of producing work which shall be respected—he says it boldly—‘in all companies and for all time
18
.’ To be thorough; to aim at solid results—this rule, meant first for writers, was not less needed in that age for the future men of action; and in literature it had this special result, that literary skill, seeking some enduring form in which it might embody itself, was now applied with a new zeal to history. Three pupils of Isokrates are especially representative of this impulse. Androtion, in his
Atthis, treated the local traditions and antiquities of Attica, and carried the history of Athens at least to 394 B.C. Ephoros wrote a History of Greece, in thirty books, from the Return of the Herakleidae to the siege of Perinthos by Philip in 341 B. C. Theopompos was the author of a supplement to Thucydides—relating, in twelve books, the events from the battle of Kynossema to the battle of Knidos (411—394 B. C.); and, in his
Philippica, a work in no less than fifty-eight books, made Philip of Macedon the central figure of what seems to have been in fact a History of Civilization, arranged as a great picture of the contemporary world
19
. It
was a benefit to an age intellectually poor in all but speculative interests to have turned literary energy towards something more substantial than the study of form. This was done by the historical school of which Isokrates became the indirect founder, and which shows, in one special manifestation, a general bent of his teaching.
