The Literary Sources of Ancient Philosophy.[2] The literary sources of ancient philosophy are three: (1) the primary sources, or original writings; (2) the secondary sources, or reports of the original writers obtained indirectly, or through other writers; (3) the interpretations of reliable modern historians of philosophy. The specialist in philosophy will, of course, go to the first two sources for his information. Other students will find many accurate modern histories of ancient philosophy. The student should have at hand the translations of the histories of Zeller, Windelband, Weber, Eucken, Ueberweg; those of the Englishmen, Burnet and Fairbanks; of the Americans, Rogers and Turner.

“The writings of the early Greek philosophers of the pre-Socratic period exist now only in fragments. The complete works of Plato are still extant; so also are the most important works of Aristotle, and certain others which belong to the Stoic, Epicurean, Skeptic, and neo-Platonic schools.We possess the principal works of most of the philosophers of the Christian period in sufficient completeness.”[3] The secondary sources include quotations and comments upon earlier philosophers found in the writings of Plato, Aristotle, the Stoics, Skeptics, neo-Platonists, and the so-called doxographers. Doxography—the commentating upon and collating of the works of former times—developed enormously in Alexandria, Pergamos, and Rhodes just after Aristotle.The founder of this work was Theophrastus, who was a disciple of Aristotle and his successor in the Lyceum. Among the important doxographers were Plutarch, Stobæus, and Aetios.

The Environment of the Early Greek. The biologist seeks to explain a living creature by its previous environment and inherited instincts. So if we know the environment and inherited instincts of the early Greek, we shall be able to understand better firstly, why European philosophy began with the Greeks and not with some other people; and secondly, why Greek philosophy took certain lines that it did take.

(1). His Geographical Environment. The Greece into which philosophy was born was much larger than the Greece of to-day. Ancient Greece consisted of all the coasts and islands which were washed by the Mediterranean Sea from Asia Minor to Sicily and southern Italy, and from Cyrene to Thrace. The motherland, the peninsula of Greece, at first played an insignificant rôle. The leadership was in the hands of the Ionians, who had colonized the coasts of Asia Minor. In the seventh century B. C., when the first Greek philosophy appears, these Ionians commanded the world’s commerce among the three continents. Over the coasts of the entire Mediterranean they had extended their trade and established their colonies. Miletus became the wealthiest of these colonies and the cradle of Greek science. Its wealth afforded leisure to its people and therefore the opportunity for reflection.

(2). His Political Environment. An understanding of the Greek political world, in which its first philosophy appeared, requires an historical explanation of its rise. It takes us back four centuries to the age ofthe Epic (1000750 B. C.). During more than two centuries of the age of the Epic two changes occurred which were to influence future Greek civilization: (1) The oligarchy which had supplanted the ancient patriarchal monarchy became firmly established; and (2) the Epic was formed. The importance of the Epic of Homer lies not so much in the fact that a great poem was constructed, as that it was the formulation of the Greek religion, the Greek æsthetic polytheism. Its writing indicates that the earlier unorganized, primitive, and savage forms of religion had given way, among the ruling classes at least, to an æsthetic polytheism, which in a general way was fixed by the Epic itself.

The period of more than a century, from 750 to 625 B. C., lying between the age of the Epic and Greek philosophy, may be called an age of political disturbances. The oligarchy had become oppressive to the rich and poor alike. There had grown up in Greece, especially in the colonies, a class of citizens who had become wealthy through commerce. The result of the misgovernment by the oligarchy was that (1) migrations took place, and (2) many revolutions occurred. This was particularly true of the colonies where the proletariat was powerful and the cities were full of adventurers. Plutocracy was at war with aristocracy, and this was the opportunity for bold men. These political troubles took form from 650 B. C. on, and the history of the Greek cities consists of the endeavor to establish popular government. About the time of the first Greek philosophers there arose here and there from the ruins of these civil struggles the so-called tyrants, of whom Thrasybulus at Miletus, Pittacus at Lesbos, Periander at Corinth, and Pisistratus at Athens are examples.The courts of these tyrants became centres of intellectual life. They patronized poets, writers, and artists. The universalism of the Epic had vanished, and in its place came the individualism of the lyric and the satire. In many places the aristocrat went into gloomy retirement, and often cultivated poetry, science, and philosophy.

The Native Tendencies of the Early Greek. Why were the Greeks the first philosophers of Europe? Their geographical surroundings of sea and land had something to do with it.The passionate party strife between the old, ruling families of nobles and the newly rich trading-class, which took place during the seventh century B. C., no doubt cultivated an early independence of opinion and strength of personality. But, after all, genius was in the blood of the race, and who can say that the true cause was not in the mixing of the blood of the virile Aryan invaders with that of the aboriginal inhabitants? Whatever may be the answer to that question, the Greek race in the seventh century B. C. had an extraordinary curiosity about the world of nature. It loved the concrete fact as no other race of the time loved it, and it loved to give a clear and articulate expression to the concrete fact that it saw. It had an artistic nature that was hostile to all confusion. Let us point out three ways in which the Greek was even in this early time organizing his experiences, reflecting upon the workings of social and nature forces, and thus preparing the way for consideration of the more ultimate questions of philosophy.

(1) This can be seen first in the development of his religion. The first step in the organization of his religion we have already seen, for the Homeric epicwas the expression of a well-defined, poetic, and æsthetic polytheism developed out of a primitive savage naturalism. The Greek’s sense of measure was shown in the way both gods and men were placed as a part of the world of nature. He could accomplish this the more freely because he had no hierarchy of priests and no dogma of belief to cramp his imagination. The Greek priests did not penetrate into the private life nor teach religion. “They were not theologians but sacristans and liturgical functionaries.” In the fifty years before philosophy appeared, this tendency toward scientific religious organizing showed the beginning of another advance. Monistic belief, of which signs may be found even in the earlier Greek writings, came to the surface.This monism[4] was expressed or implied by the Gnomic poets, “wise poets,” so called, because they made sententious utterances upon the principles of morality.

(2) The early genius of the Greek is shown in his reflections upon physical events. The Greek had been accumulating for a long time many kinds of information, but, what is more important, he had been reflecting upon this information. The Ionian was a sea-faring man. He had had much practical experience and had made many true observations about the things he had seen. In his travels he had come in contact with the Orientals and the Egyptians, and although his scientific conceptions were probably in the main his own, hisknowledge was undoubtedly increased by his travels. In the seventh century B. C., the Greeks had a respectable body of physical science. It was mostly inorganic science, however,—astronomy, geography, and meteorology. The early Greek knowledge of organic phenomena was very meagre, as, for example, medical and physiological knowledge. They also showed little genuine research in the field of mathematics, although they had picked up mathematical information here and there. Many of the first philosophers were scientists.

(3) Not only did the Greek early bring a religious system out of the chaos of his naturalism, not only did he early throw his physical information into scientific form; but also early did he show an especial interest in human conduct. This can be seen first in Homer (800 B. C.), in a more developed form in Hesiod (700 B. C.), and with still deeper reflection in the Gnomic poets. Although the Iliad is a descriptive poem, it abounds in ethical observations. For example, Hector says, “The best omen is to fight for one’s country”; and Nestor in council says, “A wretch without the tie of kin, a lawless man without a home, is he who delights in civil strife.” The poem by Hesiod (Works and Days) is intended to teach morals. It is distinctly a didactic poem. Hesiod stands at the beginning of a long line of Greek ethical teachers. His moral observations are, however, incoherently expressed. They are not wide generalizations, but are only comments upon single experiences. The Gnomic poets appeared at the end of the seventh century B. C., as the moral reformers in the age of political disturbances. This period was called by the Greeks the age of the Seven Wise Men; for among the men who were thenexhorting the age to come back to its senses,tradition early selected seven of the most notable.[5] The spirit of Gnomic poetry was prominent in their reported sayings. They were fearful because of the common disregard of the conventions of the previous age, and because of the present excesses. Their watchword was “moderation,” and they were ever repeating “nothing too much.” By apothegm, riddle, epigram, and catchwords they tried to reform society. The names of all seven are not certain, and only four of them are known,—Thales, Solon, Pittacus, and Bias. Their ethical reflections are not concerned, as in Hesiod, with the home, the village, and the rules of convention, but with the individual’s general relation to society. Their knowledge of ethical matters is remarkable for their time. Some of their sayings are as follows:—
