(34) The sect of the Stoics was founded by Zeno (340-265 B.C.), the Cittiean, who studied under Crates the Cynic, from which sect the Stoics had their origin. Zeno was succeeded by Cleanthes, Chrysippus, Zeno of Tarsis, Diogenes, Antipater, Panætius, and Posidonius. Most famous of the Roman Stoics are Epictetus and Marcus Aurelius. The Stoics were essentially pantheists, since they maintained that as there is nothing better than the world, the world is God. Zeno declared that the reason of the world is diffused throughout it as seed. Stoicism is a materialistic philosophy, enjoining voluntary resignation to natural law. Chrysippus maintained that good and evil being contrary, both are necessary since each sustains the other. The soul was regarded as a body distributed throughout the physical form and subject to dissolution with it. Though some of the Stoics held that wisdom prolonged the existence of the soul, actual immortality is not included in their tenets. The soul was said to be composed of eight parts: the five senses, the generative power, the vocal power, and an eighth, or hegemonic, part. Nature was defined as God mixed throughout the substance of the world. All things were looked upon as bodies either corporeal or incorporeal.

(7) In this age the word philosophy has little meaning unless accompanied by some other qualifying term. The body of philosophy has been broken up into numerous isms more or less antagonistic, which have become so concerned with the effort to disprove each other's fallacies that the sublimer issues of divine order and human destiny have suffered deplorable neglect. The ideal function of philosophy is to serve as the stabilizing influence in human thought. By virtue of its intrinsic nature it should prevent man from ever establishing unreasonable codes of life. Philosophers themselves, however, have frustrated the ends of philosophy by exceeding in their woolgathering those untrained minds whom they are supposed to lead in the straight and narrow path of rational thinking. To list and classify any but the more important of the now recognized schools of philosophy is beyond the space limitations of this volume. The vast area of speculation covered by philosophy will be appreciated best after a brief consideration of a few of the outstanding systems of philosophic discipline which have swayed the world of thought during the last twenty-six centuries. The Greek school of philosophy had its inception with the seven immortalized thinkers upon whom was first conferred the appellation of Sophos, "the wise." According to Diogenes Laertius, these were Thales, Solon, Chilon, Pittacus, Bias, Cleobulus, and Periander. Water was conceived by Thales to be the primal principle or element, upon which the earth floated like a ship, and earthquakes were the result of disturbances in this universal sea. Since Thales was an Ionian, the school perpetuating his tenets became known as the Ionic. He died in 546 B.C., and was succeeded by Anaximander, who in turn was followed by Anaximenes, Anaxagoras, and Archelaus, with whom the Ionic school ended. Anaximander, differing from his master Thales, declared measureless and indefinable infinity to be the principle from which all things were generated. Anaximenes asserted air to be the first element of the universe; that souls and even the Deity itself were composed of it.

(28) After the death of Plato, his disciples separated into two groups. One, the Academics, continued to meet in the Academy where once he had presided; the other, the Peripatetics, removed to the Lyceum under the leadership of Aristotle (384-322 B.C.). Plato recognized Aristotle as his greatest disciple and, according to Philoponus, referred to him as "the mind of the school." If Aristotle were absent from the lectures, Plato would say: "The intellect is not here." Of the prodigious genius of Aristotle, Thomas Taylor writes in his introduction to The Metaphysics:

(12) The Eleatic sect was founded by Xenophanes (570-480 B.C.), who was conspicuous for his attacks upon the cosmologic and theogonic fables of Homer and Hesiod. Xenophanes declared that God was "one and incorporeal, in substance and figure round, in no way resembling man; that He is all sight and all hearing, but breathes not; that He is all things, the mind and wisdom, not generate but eternal, impassible, immutable, and rational." Xenophanes believed that all existing things were eternal, that the world was without beginning or end, and that everything which was generated was subject to corruption. He lived to great age and is said to have buried his sons with his own hands. Parmenides studied under Xenophanes, but never entirely subscribed to his doctrines. Parmenides declared the senses to be uncertain and reason the only criterion of truth. He first asserted the earth to be round and also divided its surface into zones of hear and cold.

(1) The successor, however, of Pythagoras, is acknowledged by all men to have been Aristæus, the son of Damophon the Crotonian, who existing at the same time as Pythagoras, was seven ages prior to Plato. Aristæus likewise, was not only thought worthy to succeed Pythagoras in his school, but also to educate his children, and marry his wife Theano, because he was eminently skilled in the Pythagoric dogmas. For Pythagoras himself is said to have taught in his school, forty years wanting one, and to have lived nearly one hundred years. But Aristæus, when much advanced in years, relinquished the school; and after him Mnesarchus succeeded, who was the son of Pythagoras. Bulagoras succeeded Mnesarchus, in whose time it happened that the city of the Crotonians was plundered. Gartydas the Crotonian succeeded Bulagoras, on his return from a journey which he had undertaken prior to the war. Nevertheless on account of the calamity of his country, he suffered so much anxiety, as to die prematurely through grief. But it was the custom with the rest of the Pythagoreans, when they became very old, to liberate themselves from the body as from a prison.

(19) The Megarians are occasionally included among the dialectic philosophers. Euclid (who died 374? B.C.) was succeeded in his school by Eubulides, among whose disciples were Alexinus and Apollonius Cronus. Euphantus, who lived to great age and wrote many tragedies, was among the foremost followers of Eubulides. Diodorus is usually included in the Megarian school, having heard Eubulides lecture. According to legend, Diodorus died of grief because he could not answer instantly certain questions asked him by Stilpo, at one time master of the Megarian school. Diodorus held that nothing

(17) The Elean sect was founded by Phædo of Elis, a youth of noble family, who was bought from slavery at the instigation of Socrates and who became his devoted disciple. Plato so highly admired Phædo's mentality that he named one of the most famous of his discourses The Phædo. Phædo was succeeded in his school by Plisthenes, who in turn was followed by Menedemus. Of the doctrines of the Elean sect little is known. Menedemus is presumed to have been inclined toward the teachings of Stilpo and the Megarian sect. When Menedemus' opinions were demanded, he answered that he was free, thus intimating that most men were enslaved to their opinions. Menedemus was apparently of a somewhat belligerent temperament and often returned from his lectures in a badly bruised condition. The most famous of his propositions is stated thus: That which is not the same is different from that with which it is not the same. This point being admitted, Menedemus continued: To benefit is not the same as good, therefore good does not benefit. After the time of Menedemus the Elean sect became known as the Eretrian. Its exponents denounced all negative propositions and all complex and abstruse theories, declaring that only affirmative and simple doctrines could be true.

(22) The Cynics were a sect founded by Antisthenes of Athens (444-365? B.C.), a disciple of Socrates. Their doctrine may be described as an extreme individualism which considers man as existing for himself alone and advocates surrounding him by inharmony, suffering, and direst need that be may thereby be driven to retire more completely into his own nature. The Cynics renounced all worldly possessions, living in the rudest shelters and subsisting upon the coarsest and simplest food. On the assumption that the gods wanted nothing, the Cynics affirmed that those whose needs were fewest consequently approached closest to the divinities. Being asked what he gained by a life of philosophy, Antisthenes replied that he had learned how to converse with himself.

(26) The sect of the Academic philosophers instituted by Plato (427-347 B.C.) was divided into three major parts--the old, the middle, and the new Academy. Among the old Academics were Speusippus, Zenocrates, Poleman, Crates, and Crantor. Arcesilaus instituted the middle Academy and Carneades founded the new. Chief among the masters of Plato was Socrates. Plato traveled widely and was initiated by the Egyptians into the profundities of Hermetic philosophy. He also derived much from the doctrines of the Pythagoreans. Cicero describes the threefold constitution of Platonic philosophy as comprising ethics, physics, and dialectics. Plato defined good as threefold in character: good in the soul, expressed through the virtues; good in the body, expressed through the symmetry and endurance of the parts; and good in the external world, expressed through social position and companionship. In The Book of Speusippus on Platonic Definitions, that great Platonist thus defines God: "A being that lives immortally by means of Himself alone, sufficing for His own blessedness, the eternal Essence, cause of His own goodness. According to Plato, the One is the term most suitable for defining the Absolute, since the whole precedes the parts and diversity is dependent on unity, but unity not on diversity. The One, moreover, is before being, for to be is an attribute or condition of the One.

(11) After Pythagoras of Samos, its founder, the Italic or Pythagorean school numbers among its most distinguished representatives Empedocles, Epicharmus, Archytas, Alcmæon, Hippasus, Philolaus, and Eudoxus. Pythagoras (580-500? B.C.) conceived mathematics to be the most sacred and exact of all the sciences, and demanded of all who came to him for study a familiarity with arithmetic, music, astronomy, and geometry. He laid special emphasis upon the philosophic life as a prerequisite to wisdom. Pythagoras was one of the first teachers to establish a community wherein all the members were of mutual assistance to one another in the common attainment of the higher sciences. He also introduced the discipline of retrospection as essential to the development of the spiritual mind. Pythagoreanism may be summarized as a system of metaphysical speculation concerning the relationships between numbers and the causal agencies of existence. This school also first expounded the theory of celestial harmonics or "the music of the spheres." John Reuchlin said of Pythagoras that he taught nothing to his disciples before the discipline of silence, silence being the first rudiment of contemplation. In his Sophist, Aristotle credits Empedocles with the discovery of rhetoric. Both Pythagoras and Empedocles accepted the theory of transmigration, the latter saying: "A boy I was, then did a maid become; a plant, bird, fish, and in the vast sea swum." Archytas is credited with invention of the screw and the crane. Pleasure he declared to be a pestilence because it was opposed to the temperance of the mind; he considered a man without deceit to be as rare as a fish without bones.

(2) Moreover, some time after, Aresas Lucanus, being saved through certain strangers, undertook the management of the school; and to him came Diodorus Aspendius, who was received into the school, on account of the paucity of the Pythagoreans it contained. And in Heraclea, indeed, were Clinias and Philolaus; but at Metapontum, Theorides and Eurytus; and at Tarentum Archytas. It is also said that Epicharmus was one of the foreign auditors; but that he was not one of the school. Having however arrived at Syracuse, he abstained from philosophizing openly, on account of the tyranny of Hiero. But he inserted the conceptions of the men in metre, and published in comedies the occult dogmas of Pythagoras.

(16) The principles of all things he conceived to be three in number: God, matter, and ideas. Of God he said: "What He is I know not; what He is not I know." Matter he defined as the subject of generation and corruption; idea, as an incorruptible substance--the intellect of God. Wisdom he considered the sum of the virtues. Among the prominent members of the Socratic sect were Xenophon, Æschines, Crito, Simon, Glauco, Simmias, and Cebes. Professor Zeller, the great authority on ancient philosophies, has recently declared the writings of Xenophon relating to Socrates to be forgeries. When The Clouds of Aristophanes, a comedy written to ridicule the theories of Socrates, was first presented, the great Skeptic himself attended the play. During the performance, which caricatured him seated in a basket high in the air studying the sun, Socrates rose calmly in his seat, the better to enable the Athenian spectators to compare his own unprepossessing features with the grotesque mask worn by the actor impersonating him.

(18) The Megarian sect was founded by Euclid of Megara (not the celebrated mathematician), a great admirer of Socrates. The Athenians passed a law decreeing death to any citizen of Megara found in the city of Athens. Nothing daunted, Euclid donned woman's clothing and went at night to study with Socrates. After the cruel death of their teacher, the disciples of Socrates, fearing a similar fate, fled to Megara, where they were entertained with great honor by Euclid. The Megarian school accepted the Socratic doctrine that virtue is wisdom, adding to it the Eleatic concept that goodness is absolute unity and all change an illusion of the senses. Euclid maintained that good has no opposite and therefore evil does not exist. Being asked about the nature of the gods, he declared himself ignorant of their disposition save that they hated curious persons.

(15) Socrates (469-399 B.C.), the founder of the Socratic sect, being fundamentally a Skeptic, did not force his opinions upon others, but through the medium of questionings caused each man to give expression to his own philosophy. According to Plutarch, Socrates conceived every place as appropriate for reaching in that the whole world was a school of virtue. He held that the soul existed before the body and, prior to immersion therein, was endowed with all knowledge; that when the soul entered into the material form it became stupefied, but that by discourses upon sensible objects it was caused to reawaken and to recover its original knowledge. On these premises was based his attempt to stimulate the soul-power through irony and inductive reasoning. It has been said of Socrates that the sole subject of his philosophy was man. He himself declared philosophy to be the way of true happiness and its purpose twofold: (1) to contemplate God, and (2) to abstract the soul from corporeal sense.

(33) Of Skepticism as propounded by Pyrrho of Elis (365-275 B.C.) and by Timon, Sextus Empiricus said that those who seek must find or deny they have found or can find, or persevere in the inquiry. Those who suppose they have found truth are called Dogmatists; those who think it incomprehensible are the Academics; those who still seek are the Skeptics. The attitude of Skepticism towards the knowable is summed up by Sextus Empiricus in the following words: "But the chief ground of Skepticism is that to every reason there is an opposite reason equivalent, which makes us forbear to dogmatize." The Skeptics were strongly opposed to the Dogmatists and were agnostic in that they held the accepted theories regarding Deity to be self-contradictory and undemonstrable. "How," asked the Skeptic, "can we have indubitate knowledge of God, knowing not His substance, form or place; for, while philosophers disagree irreconcilably on these points, their conclusions cannot be considered as undoubtedly true?" Since absolute knowledge was considered unattainable, the Skeptics declared the end of their discipline to be: "In opinionatives, indisturbance; in impulsives, moderation; and in disquietives, suspension."

(23) Diogenes of Sinopis is remembered chiefly for the tub in the Metroum which for many years served him as a home. The people of Athens loved the beggar-philosopher, and when a youth in jest bored holes in the tub, the city presented Diogenes with a new one and punished the youth. Diogenes believed that nothing in life can be rightly accomplished without exercitation. He maintained that everything in the world belongs to the wise, a declaration which he proved by the following logic: "All things belong to the gods; the gods are friends to wise persons; all things are common amongst friends; therefore all things belong to the wise." Among the Cynics are Monimus, Onesicritus, Crates, Metrocles, Hipparchia (who married Crates), Menippus, and Menedemus.

(1) As he therefore thus prepared his disciples for erudition, he did not immediately receive into the number of his associates those who came to him for that purpose, till he had made trial of, and judiciously examined them. Hence in the first place he inquired after what manner they associated with their parents, and the rest of their relatives. In the next place he surveyed their unseasonable laughter, their silence, and their speaking when it was not proper; and farther still, what their desires were, with whom they associated, how they conversed with them, in what they especially employed their leisure time in the day, and what were the subjects of their joy and grief. He likewise surveyed, their form, their mode of walking, and the whole motion of their body.

Physiognomically also considering the natural indications of their frame, he made them to be manifest signs of the unapparent manners of the soul. When, therefore, he had thus made trial of some one, he suffered him to be neglected for three years, in the mean time observing how he was disposed with respect to stability, and a true love of learning, and if he was sufficiently prepared with reference to glory, so as to despise [popular] honor. After this, he ordered those who came to him to observe a quinquennial silence, in order that he might experimentally know how they were affected as to continence of speech, the subjugation of the tongue being the most difficult of all victories; as those have unfolded to us who instituted the mysteries.

During this [probationary] time, however, the property of each was disposed of in common, and was committed to the care of those appointed for this purpose, who were called politicians, economizers, and legislators. And with respect to these probationers, those who appeared to be worthy to participate of his dogmas, from the judgment he had formed of them from their life and the modesty of their behaviour, after the quinquennial silence, then became Esoterics , and both heard and saw Pythagoras himself within the veil. For prior to this they participated of his words through the hearing alone, beyond the veil, without at all seeing him, giving for a long time a specimen of their peculiar manners. But if they were rejected they received the double of the wealth which they brought, and a tomb was raised to them as if they were dead by the homacoï ; for thus all the disciples of the man were called.

And if they happened to meet with them afterwards, they behaved to them as if they were other persons, but said that they were dead, whom they had modelled by education, in the expectation that they would become truly good men by the disciplines they would learn. They also were of opinion that those who were more slow in the acquisition of knowledge, were badly organized, and, as I may say, imperfect and barren. If, however, after Pythagoras had physiognomically considered their form, their mode of walking, and every other motion, and the state of their body, and he had conceived good hope respecting them; after likewise the quinquennial silence, and the orgies and initiations from so many disciplines, together with the ablutions of the soul, and so many and such great purifications produced from such various theorems, through which the sagacity and sanctity of the soul is perfectly ingenerated; if, after all this, some one was found to be still sluggish and of a dull intellect, they raised to such a one in the school a certain pillar and monument, (as they are said to have done to Perialus the Thurian, and Cylon the prince of the Sybarites, who were rejected by them) expelled him from the Homacoïon or auditory, loading him with a great quantity of silver and gold.

For these were deposited by them in common, and were committed to the care of certain persons adapted to this purpose, and who were called Economics, from the office which they bore. And if afterwards they happened to meet with such a one, they conceived him to be any other person, than him who according to them was dead. Hence also Lysis, blaming a certain person named Hipparchus, because he had communicated the doctrines of the Pythagoreans to the profane, and to those who acceded to them without disciplines and theory, says as follows:

(4) There was, however, a certain person named Hippomedon, an Ægean, a Pythagorean and one of the Acusmatici, who asserted that Pythagoras gave the reasons and demonstrations of all these precepts, but that in consequence of their being delivered to many, and these such as were of a more sluggish genius, the demonstrations were taken away, but the problems themselves were left. Those however of the Pythagoreans that are called Mathematici , acknowledge that these reasons and demonstrations were added by Pythagoras, and they say still more than this, and contend that their assertions are true, but affirm that the following circumstance was the cause of the dissimilitude. Pythagoras, say they, came from Ionia and Samos, during the tyranny of Polycrates, Italy being then in a florishing condition; and the first men in the city became his associates.

But, to the more elderly of these, and who were not at leisure [for philosophy], in consequence of being occupied by political affairs, the discourse of Pythagoras was not accompanied with a reasoning process, because it would have been difficult for them to apprehend his meaning through disciplines and demonstrations; and he conceived they would nevertheless be benefited by knowing what ought to be done, though they were destitute of the knowledge of the why : just as those who are under the care of physicians, obtain their health, though they do not hear the reason of every thing which is to be done to them. But with the younger part of his associates, and who were able both to act and learn,—with these he conversed through demonstration and disciplines.

These therefore are the assertions of the Mathematici, but the former, of the Acusmatici. With respect to Hippasus however especially, they assert that he was one of the Pythagoreans, but that in consequence of having divulged and described the method of forming a sphere from twelve pentagons, he perished in the sea, as an impious person, but obtained the renown of having made the discovery. In reality, however, this as well as every thing else pertaining to geometry, was the invention of that man ; for thus without mentioning his name, they denominate Pythagoras. But the Pythagoreans say, that geometry was divulged from the following circumstance: A certain Pythagorean happened to lose the wealth which he possessed; and in consequence of this misfortune, he was permitted to enrich himself from geometry.

But geometry was called by Pythagoras Historia . And thus much concerning the difference of each mode of philosophising, and the classes of the auditors of Pythagoras. For those who heard him either within or without the veil, and those who heard him accompanied with seeing, or without seeing him, and who are divided into interior and exterior auditors, were no other than these. And it is requisite to arrange under these, the political, economic and legislative Pythagoreans.

(24) The Cyrenaic sect, founded by Aristippus of Cyrene (435-356? B.C.), promulgated the doctrine of hedonism. Learning of the fame of Socrates, Aristippus journeyed to Athens and applied himself to the teachings of the great Skeptic. Socrates, pained by the voluptuous and mercenary tendencies of Aristippus, vainly labored to reform the young man. Aristippus has the distinction of being consistent in principle and practice, for he lived in perfect harmony with his philosophy that the quest of pleasure was the chief purpose of life. The doctrines of the Cyrenaics may be summarized thus: All that is actually known concerning any object or condition is the feeling which it awakens in man's own nature. In the sphere of ethics that which awakens the most pleasant feeling is consequently to be esteemed as the greatest good. Emotional reactions are classified as pleasant or gentle, harsh, and mean. The end of pleasant emotion is pleasure; the end of harsh emotion, grief; the end of mean emotion, nothing.

(1) It remains therefore after this, that we should relate how he travelled, what places he first visited, what discourses he made, on what subjects, and to whom they were addressed; for thus we shall easily apprehend the nature of his association with the men of that time. It is said then, that as soon as he came to Italy and Sicily, which cities he understood had oppressed each other with slavery, partly at some distant period of past time, and partly at a recent period, he inspired the inhabitants with a love of liberty, and through the means of his auditors, restored to independence and liberated Crotona, Sybaris, Catanes, Rhegium, Himæra, Agrigentum, Tauromenas, and some other cities, for whom also he established laws, through Charondas the Catanæan, and Zaleucus the Locrian, by whom they became florishing cities, and afforded an example worthy of imitation, for a long time, to the neighbouring kingdoms.

He also entirely subverted sedition, discord, and party zeal, not only from his familiars, and their posterity, for many generations, as we are informed by history, but, in short, from all the cities in Italy and Sicily, which were at that time disturbed with intestine and external contentions. For the following apothegm was always employed by him in every place, whether in the company of a multitude or a few, which was similar to the persuasive oracle of a God, and was an epitome and summary as it were of his own opinions; that we should avoid and amputate by every possible artifice, by fire and sword, and all-various contrivances, from the body, disease; from the soul, ignorance; from the belly, luxury; from a city, sedition; from a house, discord; and at the same time, from all things, immoderation: through which, with a most fatherly affection, he reminded each of his disciples of the most excellent dogmas.

Such therefore was the common form of his life at that time, both in words and actions. If, however, it be requisite to make a more particular relation of what he did and said, it must be observed, that he came to Italy in the sixty-second Olympiad, at which time Eryxidas of Chalcis conquered in the stadium. But immediately on his arrival he became conspicuous and illustrious, in the same manner as before, when he sailed to Delos. For there, when he performed his adorations at the bloodless altar of the father Apollo, he was admired by the inhabitants of the island.
