His character should be viewed in both its main aspects—the political and the literary.
With regard to the first, two questions have to be asked: (1) How far were the political views of Isocrates peculiar to himself, and different from those of the clearest minds contemporary with him? (2) How far were those views falsified by the event?
1. The whole tone of Greek thought in that age had taken a bent towards monarchy in some form. This tendency may be traced alike in the practical common sense of Xenophon and in the lofty idealism of Plato. There could be no better instance of it than a well-known passage in the Politics of Aristotle. He is speaking of the gifts which meet in the Greek race—a race warlike, like the Europeans, but more subtle—keen, like the Asiatics, but braver. Here, he says, is a race which “might rule all men, if it were brought under a single government.”[11] It is unnecessary to suppose a special allusion to Alexander; but it is probable that Aristotle had in his mind a possible union of the Greek cities under a strong constitutional monarchy. His advice to Alexander (as reported by Plutarch) was to treat the Greeks in the spirit of a leader (ἡγεμονικῶς) and the barbarians in the spirit of a master (δεσποτικῶς).[12] Aristotle conceived the central power as political and permanent; Isocrates conceived it as, in the first place, military, having for its immediate aim the conduct of an expedition against Asia. The general views of Isocrates as to the largest good possible for the Greek race were thus in accord with the prevailing tendency of the best Greek thought in that age.
2. The vision of the Greek race “brought under one polity” was not, indeed, fulfilled in the sense of Aristotle or of Isocrates. But the invasion of Asia by Alexander, as captain-general of Greece, became the event which actually opened new and larger destinies to the Greek race. The old political life of the Greek cities was worn out; in the new fields which were now opened, the empire of Greek civilization entered on a career of world-wide conquest, until Greece became to East and West more than all that Athens had been to Greece. Athens, Sparta, Thebes, ceased indeed to be the chief centres of Greek life; but the mission of the Greek mind could scarcely have been accomplished with such expansive and penetrating power if its influence had not radiated over the East from Pergamum, Antioch and Alexandria.
Panhellenic politics had the foremost interest for Isocrates. But in two of his works—the oration On the Peace and the Areopagiticus (both of 355 B.C.)—he deals specially with the politics of Athens. The speech On the Peace relates chiefly to foreign affairs. It is an eloquent appeal to his fellow-citizens to abandon the dream of supremacy, and to treat their allies as equals, not as subjects. The fervid orator personifies that empire, that false mistress which has lured Athens, then Sparta, then Athens once more, to the verge of destruction. “Is she not worthy of detestation?” Leadership passes into empire; empire begets insolence; insolence brings ruin. The Areopagiticus breathes a kindred spirit in regard to home policy. Athenian life had lost its old tone. Apathy to public interests, dissolute frivolity, tawdry display and real poverty—these are the features on which Isocrates dwells. With this picture he contrasts the elder democracy of Solon and Cleisthenes, and, as a first step towards reform, would restore to the Areopagus its general censorship of morals. It is here, and here alone—in his comments on Athenian affairs at home and abroad—that we can distinctly recognize the man to whom the Athens of Pericles was something more than a tradition. We are carried back to the age in which his long life began. We find it difficult to realize that the voice to which we listen is the same which we hear in the letter to Philip.
Turning from the political to the literary aspect of his work, we are at once upon ground where the question of his merits will now provoke comparatively little controversy. Perhaps the most serious prejudice with which his reputation has had to contend in modern times has been due to an accident of verbal usage. He repeatedly describes that art which he professed to teach as his φιλοσοφία. His use of this word—joined to the fact that in a few passages he appears to allude slightingly to Plato or to the Socratics—has exposed him to a groundless imputation. It cannot be too distinctly understood that, when Isocrates speaks of his φιλοσοφία, he means simply his theory or method of “culture”—to use the only modern term which is really equivalent in latitude to the Greek word as then current.[13]
The φιλοσοφία, or practical culture, of Isocrates was not in conflict, because it had nothing in common, with the Socratic or Platonic philosophy. The personal influence of Socrates may, indeed, be traced in his work. He constantly desires to make his teaching bear on the practical life. His maxims of homely moral wisdom frequently recall Xenophon’s Memorabilia. But there the relation ends. Plato alludes to Isocrates in perhaps three places. The glowing prophecy in the Phaedrus has been quoted; in the Gorgias a phrase of Isocrates is wittily parodied; and in the Euthydemus Isocrates is probably meant by the person who dwells “on the borderland between philosophy and statesmanship.”[14] The writings of Isocrates contain a few more or less distinct allusions to Plato’s doctrines or works, to the general effect that they are barren of practical result.[15] But Isocrates nowhere assails Plato’s philosophy as such. When he declares “knowledge” (ἐπιστήμη) to be unattainable, he means an exact “knowledge” of the contingencies which may arise in practical life. “Since it is impossible for human nature to acquire any science (ἐπιστήμην) by which we should know what to do or to say, in the next resort I deem those wise who, as a rule, can hit what is best by their opinions” (δόξας).[16]
Isocrates should be compared with the practical teachers of his day. In his essay Against the Sophists, and in his speech on the Antidosis, which belong respectively to the beginning and the close of his professional career, he has clearly marked the points which distinguish him from “the sophists of the herd” (ἀγελαῖοι σοφισταί). First, then, he claims, and justly, greater breadth of view. The ordinary teacher confined himself to the narrow scope of local interests—training the young citizen to plead in the Athenian law courts, or to speak on Athenian affairs in the ecclesia. Isocrates sought to enlarge the mental horizon of his disciples by accustoming them to deal with subjects which were not merely Athenian, but, in his own phrase, Hellenic. Secondly, though he did not claim to have found a philosophical basis for morals, it has been well said of him that “he reflects the human spirit always on its nobler side,”[17] and that, in an age of corrupt and impudent selfishness, he always strove to raise the minds of his hearers into a higher and purer air. Thirdly, his method of teaching was thorough. Technical exposition came first. The learner was then required to apply the rules in actual composition, which the master revised. The ordinary teachers of rhetoric (as Aristotle says) employed their pupils in committing model pieces to memory, but neglected to train the learner’s own faculty through his own efforts. Lastly, Isocrates stands apart from most writers of that day in his steady effort to produce results of permanent value. While rhetorical skill was largely engaged in the intermittent journalism of political pamphlets, Isocrates set a higher ambition before his school. His own essays on contemporary questions received that finished form which has preserved them to this day. The impulse to solid and lasting work, communicated by the example of the master, was seen in such monuments as the Atthis of Androtion, the Hellenics of Theopompus and the Philippica of Ephorus.
In one of his letters to Atticus, Cicero says that he has used “all the fragrant essences of Isocrates, and all the little stores of his disciples.”[18] The phrase has a point of which the writer himself was perhaps scarcely conscious: the style of Isocrates had come to Cicero through the school of Rhodes; and the Rhodian imitators had more of Asiatic splendour than of Attic elegance. But, with this allowance made, the passage may serve to indicate the real place of Isocrates in the history of literary style. The old Greek critics consider him as representing what they call the “smooth” or “florid” mode of composition (γλαφυρά, ἀνθηρὰ ἀρμονία) as distinguished from the “harsh” (αὐστηρά) style of Antiphon and the perfect “mean” (μέση) of Demosthenes. Tried by a modern standard, the language of Isocrates is certainly not “florid.” The only sense in which he merits the epithet is that (especially in his earlier work) he delights in elaborate antitheses. Isocrates is an “orator” in the larger sense of the Greek word rhetor; but his real distinction consists in the fact that he was the first Greek who gave an artistic finish to literary rhetoric. The practical oratory of the day had already two clearly separated branches—the forensic, represented by Isaeus, and the deliberative, in which Callistratus was the forerunner of Demosthenes. Meanwhile Isocrates was giving form and rhythm to a standard literary prose. Through the influence of his school, this normal prose style was transmitted—with the addition of some florid embellishments—to the first generation of Romans who studied rhetoric in the Greek schools. The distinctive feature in the composition of Isocrates is his structure of the periodic sentence. This, with him, is no longer rigid or monotonous, as with Antiphon—no longer terse and compact, as with Lysias—but ample, luxuriant, unfolding itself (to use a Greek critic’s image) like the soft beauties of a winding river. Isocrates was the first Greek who worked out the idea of a prose rhythm. He saw clearly both its powers and its limits; poetry has its strict rhythms and precise metres; prose has its metres and rhythms, not bound by a rigid framework, yet capable of being brought under certain general laws which a good ear can recognize, and which a speaker or writer may apply in the most various combinations. This fundamental idea of prose rhythm, or number, is that which the style of Isocrates has imparted to the style of Cicero. When Quintilian (x. 1. 108) says, somewhat hyperbolically, that Cicero has artistically reproduced (effinxisse) “the force of Demosthenes, the wealth of Plato, the charm of Isocrates,” he means principally this smooth and harmonious rhythm. Cicero himself expressly recognizes this original and distinctive merit of Isocrates.[19] Thus, through Rome, and especially through Cicero, the influence of Isocrates, as the founder of a literary prose, has passed into the literatures of modern Europe. It is to the eloquence of the preacher that we may perhaps look for the nearest modern analogue of that kind in which Isocrates excelled—especially, perhaps, to that of the great French preachers. Isocrates was one of the three Greek authors, Demosthenes and Plato being the others, who contributed most to form the style of Bossuet.
Works.—The extant works of Isocrates consist of twenty-one speeches or discourses and nine letters.[20] Among these, the six forensic speeches represent the first period of his literary life—belonging to the years 403-393 B.C. All six concern private causes. They may be classed as follows: 1. Action for Assault (δίκη αἰκίας), Or. xx., Against Lochites, 394 B.C. 2. Claim to an Inheritance (ἐπιδικασία), Or. xix., Aegineticus, end of 394 or early in 393 B.C. 3. Actions to Recover a Deposit: (1) Or. xxi., Against Euthynus, 403 B.C.; (2) Or. xvii., Trapeziticus, end of 394 or early in 393 B.C. 4. Action for Damage (δίκη βλάβης), Or. xvi., Concerning the Team of Horses, 397 B.C. 5. Special Plea (παραγραφή), Or. xviii., Against Callimachus, 402 B.C. Two of these have been regarded as spurious by G. E. Benseler, viz. Or. xxi., on account of the frequent hiatus and the short compact periods, and Or. xvii., on the first of these grounds. But we are not warranted in applying to the early work of Isocrates those canons which his mature style observed. The genuineness of the speech against Euthynus is recognized by Philostratus; while the Trapeziticus—thrice named without suspicion by Harpocration—is treated by Dionysius, not only as authentic, but as the typical forensic work of its author. The speech against Lochites—where “a man of the people” (τοῦ πλήθους εἶς) is the speaker—exhibits much rhetorical skill. The speech Περὶ τοῦ ζεύγους (“concerning the team of horses”) has a curious interest. An Athenian citizen had complained that Alcibiades had robbed him of a team of four horses, and sues the statesman’s son and namesake (who is the speaker) for their value. This is not the only place in which Isocrates has marked his admiration for the genius of Alcibiades; it appears also in the Philippus and in the Busiris. But, among the forensic speeches, we must, on the whole, give the palm to the Aegineticus—a graphic picture of ordinary Greek life in the islands of the Aegean. Here—especially in the narrative—Isocrates makes a near approach to the best manner of Lysias.
