7. SOCRATES AND THE SOCRATIC SCHOOLS.—Although Socrates (468-399 B.C.) left no writings behind him, yet the intellect of Greece was powerfully affected by the principles of his philosophy, and the greatest literary genius that ever appeared in Hellas owed most of his mental training to his early intercourse with him. It was by means of conversation, by a searching process of question and answer, that Socrates endeavored to lead his pupils to a consciousness of their own ignorance, and thus to awaken in their minds an anxiety to obtain more exact views. This method of questioning he reduced to a scientific process, and "dialectics" became a name for the art of reasoning and the science of logic. The subject-matter of this method was moral science considered with special reference to politics. To him may be justly attributed induction and general definitions, and he applied this practical logic to a common-sense estimate of the duties of man both as a moral being and as a member of a community, and thus he first treated moral philosophy according to scientific principles. No less than ten schools of philosophers claimed him as their head, though the majority of them imperfectly represented his doctrines. By his influence on Plato, and through him on Aristotle, he constituted himself the founder of the philosophy which is still recognized in the civilized world.
From the doctrine held by Socrates, that virtue was dependent on knowledge, Eucleides of Megara (fl. 398 B.C.), the founder of the Megaric school, submitted moral philosophy to dialectical reasoning and logical refinements; and from the Socratic principle of the union between virtue and happiness, Aristippus of Cyrene (fl. 396 B.C.) deduced the doctrine which became the characteristic of the Cyrenian school, affirming that pleasure was the ultimate end of life and the higher good; while Antisthenes (fl. 396 B.C.) constructed the Cynic philosophy, which placed the ideal of virtue in the absence of every need, and hence in the disregarding of every interest, wealth, honor, and enjoyment, and in the independence of any restraints of life and society. Diogenes of Sinope (fl. 300 B.C.) was one of the most prominent followers of this school. He, like his master, Antisthenes, always appeared in the most beggarly clothing, with the staff and wallet of mendicancy; and this ostentation of self-denial drew from Socrates the exclamation, that he saw the vanity of Antisthenes through the holes in his garments.
Plato (429-348 B.C.) was the only—one of the disciples of Socrates who represented the whole doctrines of his teacher. We owe to him that the ideas which Socrates awakened have been made the germ of one of the grandest systems of speculation that the world has ever seen, and that it has been conveyed to us in literary compositions which are unequaled in refinement of conception, or in vigor and gracefulness of style. At the age of nineteen he became one of the pupils and associates of Socrates, and did not leave him until that martyr of intellectual freedom drank the fatal cup of hemlock. He afterwards traveled in Asia Minor, in Egypt, in Italy, and Sicily, and made himself acquainted with all contemporary philosophy. During the latter part of his life he was engaged as a public lecturer on philosophy. His lectures were delivered in the gardens of the Academia, and they have left proof of their celebrity in the structure of language, which has derived from them a term now common to all places of instruction. Of the importance of the Socratic and Pythagorean elements in Plato's philosophy there can be no doubt; but he transmuted all he touched into his own forms of thought and language, and there was no branch of speculative literature which he had not mastered. By adopting the form of dialogue, in which all his extant works have come down to us, he was enabled to criticise the various systems of philosophy then current in Greece, and also to gratify his own dramatic genius, and his almost unrivaled power of keeping up an assumed character. The works of Plato have been divided into three classes: first, the elementary dialogues, or those which contain the germs of all that follows, of logic as the instrument of philosophy, and of ideas as its proper object; second, progressive dialogues, which treat of the distinction between philosophical and common knowledge, in their united application to the proposed and real sciences, ethics, and physics; third, the constructive dialogues, in which the practical is completely united with the speculative, with an appendix containing laws, epistles, etc.
The fundamental principle of Plato's philosophy is the belief in an eternal and self-existent cause, the origin of all things. From this divine Being emanate not only the souls of men, which are immortal, but that of the universe itself, which is supposed to be animated by a divine spirit. The material objects of our sight, and other senses, are mere fleeting emanations of the divine idea; it is only this idea itself that is really existent; the objects of sensuous perception are mere appearances, taking their forms by participation in the idea; hence it follows, that in Plato's philosophy all knowledge is innate, and acquired by the soul before birth, when it was able to contemplate real existences, and all our ideas of this world are mere reminiscences of their true and eternal patterns. The belief of Plato in the immortality of the soul naturally led him to establish a high standard of moral excellence, and, like his great teacher, he constantly inculcates temperance, justice, and purity of life. His political views are developed in the "Republic" and in the "Laws," in which the main feature of his system is the subordination, or rather the entire sacrifice of the individual to the state.
The style of Plato is in every way worthy of his position in universal literature, and modern scholars have confirmed the encomium of Aristotle, that all his dialogues exhibit extraordinary acuteness, elaborate elegance, bold originality, and curious speculation. In Plato, the powers of imagination were just as conspicuous as those of reasoning and reflection; he had all the chief characteristics of a poet, especially of a dramatic poet, and if his rank as a philosopher had been lower than it is, he would still have ranked high among dramatic writers for his life- like representations of the personages whose opinions he wished to combat or to defend.
Aristotle (384-322 B.C.) occupies a position among the leaders of human thought not inferior to that of his teacher, Plato. He was a native of Stagyra, in Macedonia, and is hence often called the Stagyrite. He early repaired to Athens, and became a pupil of Plato, who called him the soul of his school. He was afterwards invited by Philip of Macedon to undertake the literary education of Alexander, at that time thirteen years old. This charge continued about three years. He afterwards returned to Athens, where he opened his school in a gymnasium called the Lyceum, delivering his lessons as he walked to and fro, and from these saunters his scholars were called Peripatetics, or saunterers. During this period he composed most of his extant works. Alexander placed at his disposal a large sum for his collections in natural history, and employed some thousands of men in procuring specimens for his museum. After the death of Alexander, he was accused of blasphemy to the gods, and, warned by the fate of Socrates, he withdrew from Athens to Chalcis, where he afterwards died.
In looking at the mere catalogue of the works of Aristotle, we are struck with his vast range of knowledge. He aimed at nothing less than the completion of a general encyclopedia of philosophy. He was the author of the first scientific cultivation of each science, and there was hardly any quality distinguishing a philosopher as such, which he did not possess in an eminent degree. Of all the philosophical systems of antiquity, that of Aristotle was the best adapted to the physical wants of mankind. His works consisted of treatises on natural, moral, and political philosophy, history, rhetoric, criticism,—indeed, there was scarcely a branch of knowledge which his vast and comprehensive genius did not embrace. His greatest claim to our admiration is as a logician. He perfected and brought into form those elements of the dialectic art which had been struck out by Socrates and Plato, and wrought them, by his additions, into so complete a system, that he may be regarded as, at once, the founder and perfecter of logic as an art, which has since, even down to our own days, been but very little improved. The style of Aristotle has nothing to attract those who prefer the embellishments of a work to its subject- matter and the scientific results which it presents.
PERIOD THIRD.
EPOCH OF THE DECLINE OF GREEK LITERATURE, 322 B.C.-1453 A.D.
1. ORIGIN OF THE ALEXANDRIAN LITERATURE.—As the literary predominance of Athens was due mainly to the political importance of Attica, the downfall of Athenian independence brought with it a deterioration, and ultimately an extinction of that intellectual centralization which for more than a century had fostered and developed the highest efforts of the genius and culture of the Greeks. While the living literature of Greece was thus dying away, the conquests of Alexander prepared a new home for the muses on the coast of that wonderful country, to which all the nations of antiquity had owed a part of their science and religious belief. In Egypt, as in other regions, Alexander gave directions for the foundation of a city to be called after his own name, which became the magnificent metropolis of the Hellenic world. This capital was the residence of a family who attracted to their court all the living representatives of the literature of Greece, and stored up in their enormous library all the best works of the classical period. It was chiefly during the reigns of the first three Ptolemies that Alexandria was made the new home of Greek literature. Ptolemy Soter (306-285 B.C.) laid the foundations of the library, and instituted the museum, or temple of the muses, where the literary men of the age were maintained by endowments. This encouragement of literature was continued by Ptolemy Philadelphus (285-247 B.C.). He had the celebrated Callimachus for his librarian, who bought up not only the whole of Aristotle's great collection of works, but transferred the native annals of Egypt and Judea to the domain of Greek literature by employing the priest Manetho to translate the hieroglyphics of his own temple- archives into the language of the court, and by procuring from the Sanhedrim of Jerusalem the first part of that celebrated version of the Hebrew sacred books, which was afterwards completed and known as the Septuagint, or version of the Seventy. Ptolemy Euergetes (247-222 B.C.) increased the library by depriving the Athenians of their authentic editions of the great dramatists. In the course of time the library founded at Pergamos was transferred to Egypt, and thus we are indebted to the Ptolemies for preserving to our times all the best specimens of Greek literature which have come down to us. This encouragement of letters, however, called forth no great original genius; but a few eminent men of science, many second-rate and artificial poets, and a host of grammarians and literary pedants.
