Origin of Greek philosophy.

In Chapter II. I have described the origin and decline of Greek Mythology; in this, I am to relate the first European attempt at philosophizing. The Ionian systems spring directly out of the contemporary religious opinions, and appear as a phase in Greek comparative theology.

Contrasted with the psychical condition of India, we cannot but be struck with the feebleness of these first European efforts. They correspond to that period in which the mind has shaken off its ideas of sorcery, but has not advanced beyond geocentral and anthropocentral conceptions. As is uniformly observed, as soon as man has Its imperfections. collected what he considers to be trustworthy data, he forthwith applies them to a cosmogony, and develops pseudo-scientific systems. It is not until a later period that he awakens to the suspicion that we have no absolute knowledge of truth.

The reader, who might, perhaps, be repelled by the apparent worthlessness of the succession of Greek opinions now to be described, will find them assume an interest, if considered in the aggregate, or viewed as a series of steps or stages of European approach to conclusions long before arrived at in Egypt and India. Far in advance of anything that Greece can offer, the intellectual history of India furnishes systems at once consistent and imposing—systems not remaining useless speculations, but becoming inwoven in social life.

Commences in Asia Minor.

Greek philosophy is considered as having originated with Thales, who, though of Phœnician descent, was born at Miletus, a Greek colony in Asia Minor, about B.C. 640. At that time, as related in the last chapter, the Egyptian ports had been opened to foreigners by Psammetichus. In the civil war which that monarch had been waging with his colleagues, he owed his success to Ionian and other Greek mercenaries whom he had employed; but, though proving victor in the contest, his political position was such as to compel him to depart from the maxims followed in his country for so many thousand years, and to permit foreigners to have access to it. Hitherto the Europeans had been only known to the Egyptians as pirates and cannibals.

Doctrine of Thales

is derived from Egypt.

From the doctrine of Thales, it may be inferred that, though he had visited Egypt, he had never been in communication with its sources of learning, but had merely mingled among the vulgar, from whom he had gathered the popular notion that the first principle is water. The state of things in Egypt suggests that this primitive dogma of European philosophy was a popular notion in that country. With but little care on the part of men the fertilizing Nile-water yielded those abundant crops which made Egypt the granary of the Old World. It might therefore be said, both philosophically and facetiously, that the first principle Importance of water in Egypt. of all things is water. The harvests depended on it, and, through them, animals and man. The government of the country was supported by it, for the financial system was founded on a tax paid by the proprietors of the land for the use of the public sluices and aqueducts. There was not a peasant to whom it was not apparent that water is the first principle of all things, even of taxation; and, since it was not only necessary to survey lands to ascertain the surface that had been irrigated, but to redetermine their boundaries after the subsidence of the flood, even the scribes and surveyors might concede that geometry itself was indebted for its origin to water.

Thales asserts that water is the first principle.

If, therefore, in any part of the Old World, this doctrine had both a vulgar and a philosophical significance, that country was Egypt. We may picture to ourselves the inquisitive but ill-instructed Thales carried in some pirate-ship or trading-bark to the mysterious Nile, respecting which Ionia was full of legends and myths. He saw the aqueducts, canals, flood-gates, the great Lake Mœris, dug by the hand of man as many ages before his day as have elapsed from his day to ours; he saw on all sides the adoration paid to the river, for it had actually become deified; he learned from the vulgar, with whom alone he came in contact, their universal belief that all things arise from water—from the vulgar alone, for, had he ever been taught by the priests, we should have found traces in his system of the doctrines of emanation, transmigration, and absorption, which were imported into Greece in later times. We may interpret the story of Thales on the principles which would apply in the case of some intelligent Indian who should find his way to the outposts of a civilized country. Imperfectly acquainted with the language, and coming in contact with the lower class alone, he might learn their vulgar philosophy, and carry back the fancied treasure to his home.

As to the profound meaning which some have been disposed to extract from the dogma of Thales, we shall, perhaps, be warranted in rejecting it altogether. It has been affirmed that he attempted to concentrate all supernatural powers in one; to reduce all possible agents to unity; in short, out of polytheism to bring forth monotheism; to determine the invariable in the variable; and to ascertain the beginning of things: that he observed how infinite is the sea; how necessary moisture is to growth; nay, even how essential it was to the well-being of himself; "that without moisture his own body would not have been what it was, but a dry husk falling to pieces." Nor can we adopt the opinion that the intention of Thales was to establish a coincidence between philosophy and the popular theology as delivered by Hesiod, who affirms that Oceanus is one of the parent-gods of Nature. The imputation of irreligion made against him shows at what an early period the antagonism of polytheism and scientific inquiry was recognized. But it is possible to believe that all things are formed out of one primordial substance, without denying the existence of a creative power. Or, to use the Indian illustration, the clay may not be the potter.

Other doctrines of Thales.

Thales is said to have predicted the solar eclipse which terminated a battle between the Medes and Lydians, but it has been suggestively remarked that it is not stated that he predicted the day on which it should occur. He had an idea that warmth originates from or is nourished by humidity, and that even the sun and stars derived their aliment out of the sea at the time of their rising and setting. Indeed, he regarded them as living beings; obtaining an argument from the phenomena of amber and the magnet, supposed by him to possess a living soul, because they have a moving force. Moreover, he taught that the whole world is an insouled thing, and that it is full of dæmons. Thales had, therefore, not completely passed out of the stage of sorcery.

His system obtained importance not only from its own plausibility, but because it was introduced under favourable auspices and at a favourable time. It came into Asia Minor as a portion of the wisdom of Egypt, and therefore with a prestige sufficient to assure for it an attentive reception. But this would have been of little avail had not the mental culture of Ionia been advanced to a degree suitable for offering to it conditions of development. Under such circumstances the Egyptian dogma formed the starting-point for a special method of philosophizing.

They constitute the starting-point of Ionian philosophy.

The manner in which that development took place illustrates the vigour of the Grecian mind. In Egypt a doctrine might exist for thousands of years, protected by its mere antiquity from controversy or even examination, and hence sink with the lapse of time into an ineffectual and lifeless state; but the same doctrine brought into a young community full of activity would quickly be made productive and yield new results. As seeds taken from the coffins of mummies, wherein they have been shut up for thousands of years, when placed under circumstances favourable for development in a rich soil, and supplied with moisture, have forthwith, even in our own times, germinated, borne flowers, and matured new seeds, so the rude philosophy of Thales passed through a like development. Its tendency is shown in the attempt it at once made to describe the universe, even before the parts thereof had been determined.

Anaximenes asserts that air is the first principle.

But it is not alone the water or ocean that seems to be infinite, and capable of furnishing a supply for the origin of all other things. The air, also, appears to reach as far as the stars. On it, as Anaximenes of Miletus remarks, "the very earth itself floats like a broad leaf." Accordingly, this Ionian, stimulated doubtless by the hope of sharing in or succeeding to the celebrity that Thales had enjoyed for a century, proposed to substitute for water, as the primitive source of things, atmospheric air. And, in truth, there seem to be reasons for bestowing upon it such a pre-eminence. To those who have not looked closely into the matter, it would appear that water itself is generated from it, as when clouds are formed, and from them rain-drops, and springs, and fountains, and rivers, and even the sea. He also attributes infinity to it, a dogma scarcely requiring any exercise of the imagination, but being rather the expression of an ostensible fact; for who, when he looks upward, can discern the boundary of the atmosphere. It is also the soul. Anaximenes also held that even the human soul itself is nothing but air, since life consists in inhaling and exhaling it, and ceases as soon as that process stops. He taught also that warmth and cold arise from mere rarefaction and condensation, and gave as a proof the fact that when we breathe with the lips drawn together the air is cold, but it becomes warm when we breathe through the widely-opened mouth. Hence he concluded that, with a sufficient rarefaction, air might turn into fire, and that this probably was the origin of the sun and stars, blazing comets, and other meteors; but if by chance it should undergo condensation, it would turn into wind and clouds, or, if that operation should be still more increased, into water, snow, hail, and, at last, even into earth itself. And since it is seen from the results of The air is God. breathing that the air is a life-giving principle to man, nay, even is actually his soul, it would appear to be a just inference that the infinite air is God and that the gods and goddesses have sprung from it.

Such was the philosophy of Anaximenes. It was the beginning of that stimulation of activity by rival schools which played so distinguished a part in the Greek intellectual movement. Its superiority over the doctrine of Thales evidently consists in this, that it not only assigns a primitive substance, but even undertakes to show by observation and experiment how others arise from it, and transformations occur. As to the discovery of the obliquity of the ecliptic by the aid of a gnomon attributed to Anaximenes, it was merely a boast of his vainglorious countrymen, and altogether beyond the scientific grasp of one who had no more exact idea of the nature of the earth than that it was "like a broad leaf floating in the air."

Diogenes asserts that air is the soul of the world.

The doctrines of Anaximenes received a very important development in the hands of Diogenes of Apollonia, who asserted that all things originate from one essence, which, undergoing continual changes, becoming different at different times, turns back again to the same state. He regarded the entire world as a living being, spontaneously evolving and transforming itself, and agreed with Anaximenes that the soul of man is nothing but air, as is also the soul of the world. From this it follows that the air must be eternal, imperishable, and endowed with consciousness. "It knows much; for without reason it would be impossible for all to be arranged so duly and proportionately as that all should maintain its fitting measure, winter and summer, night and day, the rain, the wind, and fair weather; and whatever object we consider will be found to have been ordered in the best and most beautiful manner possible." "But that which has knowledge is that which men call air; it is it that regulates and governs all, and hence it is the use of air to pervade all, and to dispose all, and to be in all, for there is nothing that has not part in it."

Difficulty of rising above fetichism.

The early cultivator of philosophy emerges with difficulty from fetichism. The harmony observed among the parts of the world is easily explained on the hypothesis of a spiritual principle residing in things, and arranging them by its intelligent volition. It is not at once that he rises to the conception that all this beauty and harmony are due to the operation of law. We are so prone to judge of the process of external things from the modes of our own personal experience, our acts being determined by the exercise of our wills, that it is with difficulty we disentangle ourselves from such notions in the explanation of natural phenomena. Fetichism may be observed in the infancy of many of the natural sciences. Thus the electrical power of amber was imputed to a soul residing in that substance, a similar explanation being also given of the control of the magnet over iron. The movements of the planetary bodies, Mercury, Venus, Mars, were attributed to an intelligent principle residing in each, Astronomy and chemistry have passed beyond the fetich stage. guiding and controlling the motions, and ordering all things for the best. It was an epoch in the history of the human mind when astronomy set an example to all other sciences of shaking off its fetichism, and showing that the intricate movements of the heavenly bodies are all capable not only of being explained, but even foretold, if once was admitted the existence of a simple, yet universal, invariable, and eternal law.

Not without difficulty do men perceive that there is nothing inconsistent between invariable law and endlessly varying phenomena, and that it is a more noble view of the government of this world to impute its order to a penetrating primitive wisdom, which could foresee consequences throughout a future eternity, and provide for them in the original plan at the outset, than to invoke the perpetual intervention of an ever-acting spiritual agency for the purpose of warding off misfortunes that might happen, and setting things to rights. Chemistry furnishes us with a striking example—an example very opportune in the case we are considering—of the doctrine of Diogenes of Apollonia, that the air is actually a spiritual being; for, on the discovery of several of the gases by the earlier experimenters, they were not only regarded as of a spiritual nature, but actually received the name under which they pass to this day, gheist or gas, from a belief that they were ghosts. If a labourer descended into a well and was suffocated, as if struck dead by some invisible hand; if a lamp lowered down burnt for a few moments with a lurid flame, and was then extinguished; if, in a coal mine, when the unwary workman exposed a light, on a sudden the place was filled with flashing flames and thundering explosions, tearing down the rocks and destroying every living thing in the way, often, too, without leaving on the dead any marks of violence; what better explanation could be given of such catastrophes than to impute them to some supernatural agent? Nor was there any want, in those times, of well-authenticated stories of unearthly faces and forms seen in such solitudes.

Origin of psychology.

The modification made by Diogenes in the theory of Anaximenes, by converting it from a physical into a psychological system, is important, as marking the beginning of the special philosophy of Greece. The investigation of the intellectual development of the universe led the Greeks to the study of the intellect itself. In his special doctrine, Diogenes imputed the changeability of the air to its mobility; a property in which he thought it excelled all other substances, because it is among the rarest or thinnest of the elements. It is, however, said by some, who are disposed to transcendentalize his doctrine, that he did not mean the common atmospheric air, but something more attenuated and warm; and since, in its purest state, it constitutes the most perfect intellect, inferior degrees of reason must be owing to an increase of its density and moisture. Upon such a principle, the whole earth is animated by the breath of life; the souls of brutes, which differ from one another so much in intelligence, are only air in its various conditions of moisture and warmth. He explained the production of the world through condensation of the earth from air by cold, the warmth rising upward and forming the sun; in the stars he thought he recognized the respiratory organs of the world. From the preponderance of moist air in the constitution of brutes, he inferred that they are like the insane, incapable of thought, for thickness of the air impedes respiration, and therefore quick apprehension. From the fact that plants have no cavities wherein to receive the air, and are altogether unintelligent, he was led to the principle that the thinking power of man arises from the flowing of that substance throughout the body in the blood. He also explained the superior intelligence of men from their breathing a purer air than the beasts, which carry their nostrils near the ground. In these crude and puerile speculations we have the beginning of mental philosophy.

Modern discoveries as to the relations of the air.

I cannot dismiss the system of the Apollonian without setting in contrast with it the discoveries of modern science respecting the relations of the air. Toward the world of life it stands in a position of wonderful interest. Decomposed into its constituents by the skill of chemistry, it is no longer looked upon as a homogeneous body; its ingredients have not only been separated, but the functions they discharge have been ascertained. From one of these, carbonic acid, all the various forms of plants arise; that substance being decomposed by the rays of the sun, and furnishing to vegetables carbon, their chief solid ingredient. All those beautifully diversified organic productions, from the mosses of the icy regions to the palms characteristic of the landscapes of the tropics—all those we cast away as worthless weeds, and those for the obtaining of which we Inter-dependence of animals and plants. expend the sweat of our brow—all, without any exception, are obtained from the atmosphere by the influence of the sun. And since without plants the life of animals could not be maintained, they constitute the means by which the aërial material, vivified, as it may be said, by the rays of the sun, is conveyed even into the composition of man himself. As food, they serve to repair the waste of the body necessarily occasioned in the acts of moving and thinking. For a time, therefore, these ingredients, once a part of the structure of plants, enter as essential constituents in the structure of animals. Yet it is only in a momentary way, for the essential condition of animal activity is that there shall be unceasing interstitial death; not a finger can be lifted without the waste of muscular material; not a thought arise without the destruction of cerebral substance. From the animal system the products of decay are forthwith removed, often by mechanisms of the most exquisite construction; but their uses are not ended, for sooner or later they find their way back again into the air, and again serve for the origination of plants. It is needless to trace these changes in all their details; the same order or cycle of progress holds good for the water, the ammonia; they pass from the inorganic to the living state, and back to the inorganic again; now the same particle is found in the air next aiding in the composition of a plant, then in the body of an animal, and back in the air once more. In this perpetual Agency of the sun. revolution material particles run, the dominating influence determining and controlling their movement being in that great centre of our system, the sun. From him, in the summer days, plants receive, and, as it were, store up that warmth which, at a subsequent time, is to reappear in the glow of health of man, or to be rekindled in the blush of shame, or to consume in the burning fever. Nor is there any limit of time. The heat we derive from the combustion of stubble came from the sun as it were only yesterday; but that with which we moderate the rigour of winter when we burn anthracite or bituminous coal was also derived from the same source in the ultra-tropical climate of the secondary times, perhaps a thousand centuries ago.

In such perpetually recurring cycles are the movements of material things accomplished, and all takes place under the dominion of invariable law. The air is the source whence all organisms have come; it is the receptacle to which they all return. Its parts are awakened into life, not by the influence of any terrestrial agency or principle concealed in itself, as Diogenes supposed, but by a star which is ninety millions of miles distant, the source, direct or indirect, of every terrestrial movement, and the dispenser of light and life.

Heraclitus asserts that fire is the first principle.

To Thales and Diogenes, whose primordial elements were water and air respectively, we must add Heraclitus of Ephesus, who maintained that the first principle is fire. He illustrated the tendency which Greek philosophy had already assumed of opposition to Polytheism and the idolatrous practices of the age. It is said that in his work, ethical, political, physical, and theological subjects were so confused, and so great was the difficulty of understanding his meaning, that he obtained the surname of "the Obscure." In this respect he has had among modern metaphysicians many successors. He founds his system, however, upon the simple axiom that "all is convertible into fire, and fire into all." Perhaps by the term fire he understood what is at present meant by heat, for he expressly says that The fictitious permanence of successive forms. he does not mean flame, but something merely dry and warm. He considered that this principle is in a state of perpetual activity, forming and absorbing every individual thing. He says, "All is, and is not; for though it does in truth come into being, yet it forthwith ceases to be." "No one has ever been twice on the same stream, for different waters are constantly flowing down. It dissipates its waters and gathers them again; it approaches and recedes, overflows and fails." And to teach us that we ourselves are changing and have changed, he says, "On the same stream we embark and embark not, we are and we are not." By such illustrations he implies that life is only an unceasing motion, and we cannot fail to remark that the Greek turn of thought is fast following that of the Hindu.

But Heraclitus totally fails to free himself from local conceptions. He speaks of the motion of the primordial principle in the upward and downward directions, in the higher and lower regions. He says that the chief accumulation thereof is above, and the chief deficiency below: and hence he regards the soul of a man as a portion of fire migrated from heaven. He carries his ideas of the transitory nature of all phenomena to their last consequences, and illustrates the noble doctrine that all which appears to us to be permanent is only a regulated and self-renewing concurrence of similar and opposite motions by such extravagances as that the sun is daily destroyed and renewed.

Physical and physiological doctrines of Heraclitus.

In the midst of many wild physical statements many true axioms are delivered. "All is ordered by reason and intelligence, though all is subject to Fate." Already he perceived what the metaphysicians of our own times are illustrating, that "man's mind can produce no certain knowledge from its own interior resources alone." He regarded the organs of sense as being the channels through which the outer life of the world, and therewith truth, enters into the mind, and that in sleep, when the organs of sense are closed, we are shut out from all communion with the surrounding universal spirit. In his view every thing is animated and insouled, but to different degrees, organic objects being most completely or perfectly so. His astronomy may be anticipated from what has been said respecting the sun, which he moreover regarded as being scarcely more than a foot in diameter, and, like all other celestial objects, a mere meteor. His moral system was altogether based upon the physical, the fundamental dogma being the excellence of fire. Thus he accounted for the imbecility of the drunkard by his having a moist soul, and drew the inference that a warm or dry soul is the wisest and best; with justifiable patriotism asserting that the noblest souls must belong to a climate that is dry, intending thereby to indicate that Greece is man's fittest and truest country. There can be no doubt that in Heraclitus there is a strong tendency to the doctrine of a soul of the world. If the divinity is undistinguishable from heat, whither can we go to escape its influences? And in the restless activity and incessant changes it produces in every thing within our reach, do we not recognize the tokens of the illimitable and unshackled?

The puerility of Ionian philosophy.

I have lingered on the chief features of the early Greek philosophy as exhibited in the physical school of Ionia. They serve to impress upon us its intrinsic imperfection. It is a mixture of the physical, metaphysical, and mystical which, upon the whole, has no other value than this, that it shows how feeble were the beginnings of our knowledge—that we commenced with the importation of a few vulgar errors from Egypt. In presence of the utilitarian philosophy of that country and the theology of India, how vain and even childish are these germs of science in Greece! Yet this very imperfection is not without its use, since it warns us of the inferior position in which we stand as respects the time of our civilization when compared with those ancient states, and teaches us to reject the assertion which so many European scholars have wearied themselves in establishing, that Greece led the way to all human knowledge of any value. Above all, it impresses upon us more appropriate, because more humble views of our present attainments and position, and gives us to understand that other races of men not only preceded us in intellectual culture, but have equalled, and perhaps surpassed every thing that we have yet done in mental philosophy.

Anaximander's doctrine of the Infinite.

Of the other founders of Ionic sects it may be observed that, though they gave to their doctrines different forms, the method of reasoning was essentially the same in them all. Of this a better illustration could not be given than in the philosophy of Anaximander of Miletus, who was contemporary with Thales. He started with the postulate that things arose by separation from a universal mixture of all: his primordial principle was therefore chaos, though he veiled it in the metaphysically obscure designation "The Infinite." The want of precision in this respect gave rise to much difference of opinion as to his tenets. To his chaos he imputed an internal energy, by which its parts spontaneously separated from each other; to those parts he imputed absolute unchangeability. He taught that the earth is of a cylindrical form, its base being one-third of its altitude; it is retained in the centre of the world by the air in an equality of distance from all the boundaries of the universe; that the fixed stars and planets revolved round it, each being fastened to a crystalline ring; and beyond them, in like manner, the moon, and, still farther off, the sun. He Origin of cosmogony. conceived of an opposition between the central and circumferential regions, the former being naturally cold, and the latter hot; indeed, in his opinion, the settling of the cold parts to the centre, and the ascending of the hot, gave origin, respectively, to the formation of the earth and shining celestial bodies, the latter first existing as a complete shell or sphere, which, undergoing destruction, broke up into stars. Already we perceive the tendency of Greek philosophy to shape itself into systems of cosmogony, founded upon the disturbance Origin of biology. of the chaotic matter by heat and cold. Nay, more, Anaximander explained the origin of living creatures on like principles, for the sun's heat, acting upon the primal miry earth, produced filmy bladders or bubbles, and these, becoming surrounded with a prickly rind, at length burst open, and, as from an egg, animals came forth. At first they were ill-formed and imperfect, but subsequently elaborated and developed. As to man, so far from being produced in his perfect shape, he was ejected as a fish, and under that form continued in the muddy water until he was capable of supporting himself on dry land. Besides "the Infinite" being thus the cause of generation, it was also the cause of destruction: "things must all return whence they came, according to destiny, for they must all, in order of time, undergo due penalties and expiations of wrong-doing." This expression obviously contains a moral consideration, and is an exemplification of the commencing feeble interconnection between physical and moral philosophy.

As to the more solid discoveries attributed to this philosopher, we may dispose of them in the same manner that we have dealt with the like facts in the biographies of his predecessors—they are idle inventions of his vainglorious countrymen. That he was the first to make maps is scarcely consistent with the well-known fact that the Egyptians had cultivated geometry for that express purpose thirty centuries before he was born. As to his inventing sun-dials, the shadow had gone back on that of Ahaz a long time before. In reality, the sun-dial was a very ancient Oriental invention. And as to his being the first to make an exact calculation of the size and distance of the heavenly bodies, it need only be remarked that those who have so greatly extolled his labours must have overlooked how incompatible such discoveries are with a system which assumes that the earth is cylindrical in shape, and kept in the midst of the heavens by the atmosphere; that the sun is farther off than the fixed stars; and that each of the heavenly bodies is made to revolve by means of a crystalline wheel.

The philosopher whose views we have next to consider is Anaxagoras of Clazomene, the friend and master of Pericles, Euripides, and Socrates. Like several of his predecessors, he had visited Egypt. Among his disciples were numbered some of the most eminent men of those times.

Anaxagoras teaches the unchangeability of the universe.

The fundamental principle of his philosophy was the recognition of the unchangeability of the universe as a whole, the variety of forms that we see being produced by new arrangements of its constituent parts. Such a doctrine includes, of course, the idea of the eternity of matter. Anaxagoras says, "Wrongly do the Greeks suppose that aught begins or ceases to be, for nothing comes into being or is destroyed, but all is an aggregation or secretion of pre-existent things, so that all becoming might more correctly be called becoming-mixed, and all corruption becoming-separate." In such a statement we cannot fail to remark that the Greek is fast passing into the track of the Egyptian and the Hindu. In some respects his views recall those of the chaos of Anaximander, as when he says, "Together were The primal intellect. all things infinite in number and smallness; nothing was distinguishable. Before they were sorted, while all was together, there was no quality noticeable." To the first moving force which arranged the parts of things out of the chaos, he gave the designation of "the Intellect," rejecting Fate as an empty name, and imputing all things to Reason. He made no distinction between the Soul and Intellect. His tenets evidently include a dualism indicated by the moving force and the moved mass, an opposition between the corporeal and mental. This indicated that for philosophy there are two separate routes, the physical and intellectual. While Reason is thus the prime mover in his philosophy, he likewise employed many subordinate agents in the government of things—for instance, air, water, and fire, being evidently unable to explain the state of nature in a satisfactory way by the Cosmogony of Anaxagoras. operation of the Intellect alone. We recognize in the details of his system ideas derived from former ones, such as the settling of the cold and dense below, and the rising of the warm and light above. In the beginning the action of Intellect was only partial; that which was primarily moved was only imperfectly sorted, and contained in itself the capability of many separations. From this point his system became a cosmogony, showing how the elements and fogs, stones, stars, and the sea, were produced. These explanations, as mighty be anticipated, have no exactness. Among his primary elements are many incongruous things, such as cold, colour, fire, gold, lead, corn, marrow, blood, &c. This doctrine implied that in compound things there was not a formation, but an arrangement. It required, therefore, many elements instead of a single one. Flesh is made of fleshy particles, bones of bony, gold of golden, lead of leaden, wood of wooden, &c. These analogous constituents are homœomeriæ. Of an infinite number of kinds, they composed the infinite all, which is a mixture of them. From such conditions Anaxagoras proves that all the parts of an animal body pre-exist in the food, and are merely collected therefrom. As to the phenomena of life, he explains it on his doctrine of dualism between mind and matter; he teaches that sleep is produced by the reaction of the latter on the former. Even plants he regards as only rooted animals, motionless, but having sensations and desires; he imputes the superiority of man to the mere fact of his having hands. He explains our mental perceptions upon the hypothesis that we have naturally within us the contraries of all the qualities of external things; and that, when we consider an object, we become aware of the preponderance of those qualities in our mind which are deficient in it. Hence all sensation is attended with pain. His doctrine of the production of animals was founded on the action of the sunlight on the miry earth. The earth he places in the centre of the world, whither it was carried by a whirlwind, the pole being originally in the zenith; but, when animals issued from the mud, its position was changed by the Intellect, so that there might be suitable climates. In some particulars his crude guesses present amusing anticipations of subsequent discoveries. Thus he maintained that the moon has mountains, and valleys like the earth; that there have been grand epochs in the history of our globe, in which it has been successively modified by fire and water; that the hills of Lampsacus would one day be under the sea, if time did not too soon fail.

Doubts whether we have any criterion of truth.

As to the nature of human knowledge, Anaxagoras, asserted that by the Intellect alone do we become acquainted with the truth, the senses being altogether untrustworthy. He illustrated this by putting a drop of coloured liquid into a quantity of clear water, the eye being unable to recognize any change. Upon such principles also he asserted that snow is not white, but black, since it is composed of water, of which the colour is black; and hence he drew such conclusions as that "things are to each man according as they seem to him." It was doubtless the recognition of the unreliability of the senses that extorted from him the well-known complaint: "Nothing can be known; nothing can be learned; nothing can be certain; sense is limited; intellect is weak; life is short."

Anaxagoras is persecuted.

The biography of Anaxagoras is not without interest. Born in affluence, he devoted all his means to philosophy, and in his old age encountered poverty and want. He was accused by the superstitious Athenian populace of Atheism and impiety to the gods, since he asserted that the sun and moon consist of earth and stone, and that the so-called divine miracles of the times were nothing more than common natural effects. For these reasons, and also because of the Magianism of his doctrine—for he taught the antagonism of mind and matter, a dogma of the detested Persians—he was thrown into prison, condemned to death, and barely escaped through the influence of Pericles. He fled to Lampsacus, where he ended his days in exile. His vainglorious countrymen, however, conferred honour upon his memory in their customary exaggerated way, boasting that he was the first to explain the phases of the moon, the nature of solar and lunar eclipses, that he had the power of foretelling future events, and had even predicted the fall of a meteoric stone.

From the biography of Anaxagoras, as well as of several of his contemporaries and successors, we may learn that a popular opposition was springing up against philosophy, not limited to a mere social protest, but carried out into political injustice. The antagonism between learning and Polytheism was becoming every day more distinct. Of the philosophers, some were obliged to flee into exile, some suffered death. The natural result of such a state of things was to force them to practise concealment and mystification, as is strikingly shown in the history of the Pythagoreans.

Pythagoras, biography of.

Of Pythagoras, the founder of this sect, but little is known with certainty; even the date of his birth is contested, probably he was born at Samos about B.C. 540. If we were not expressly told so, we should recognize from his doctrines that he had been in Egypt and India. Some eminent scholars, who desire on all occasions to magnify the learning of ancient Europe, depreciate as far as they can the universal testimony of antiquity that such was the origin of the knowledge of Pythagoras, asserting that the constitution of the Egyptian priesthood rendered it impossible for a foreigner to become initiated. They forget that the ancient system of that country had been totally destroyed in the great revolution which took place more than a century before those times. If it were not explicitly stated by the ancients that Pythagoras lived for twenty-two years in Egypt, there is sufficient internal evidence in his story to prove that he had been there a long time. As a connoisseur can detect the hand of a master by the style of a picture, so one who has devoted attention to the old systems of thought sees, at a glance, the Egyptian in the philosophy of Pythagoras.

He passed into Italy during the reign of Tarquin the Proud, and settled at Crotona, a Greek colonial city on the Bay of Tarentum. At first he established a school, but, favoured by local dissensions, he gradually organized from the youths who availed themselves of his instructions a secret political society. Already it had passed into a maxim among the learned Greeks that it is not advantageous to communicate knowledge too freely to the people—a bitter experience in persecutions seemed to demonstrate that the maxim was founded on truth. The step from a secret philosophical society to a political conspiracy is but short. Pythagoras appears to have taken it. The disciples who were admitted to his scientific secrets after a period of probation and process of examination constituted a ready instrument of intrigue against the state, the issue of which, after a time, appeared in the supplanting of the ancient senate and the exaltation of Pythagoras and his club to the administration of government. The actions of men in all times are determined by similar principles; and as it would be now with such a conspiracy, so it was then; for, though the Pythagorean influence spread from Crotona to other Italian towns, an overwhelming reaction soon set in, the innovators were driven into exile, their institutions destroyed, and their founder fell a victim to his enemies.

The organization attempted by the Pythagoreans is an exception to the general policy of the Greeks. The philosophical schools had been merely points of reunion for those entertaining similar opinions; but in the state they can hardly be regarded as having had any political existence.

His miracles.

It is difficult, when the political or religious feelings of men have been engaged, to ascertain the truth of events in which they have been concerned; deception, and falsehood, seem to be licensed. In the midst of the troubles befalling Italy as the consequence of these Pythagorean machinations, it is impossible to ascertain facts with certainty. One party exalts Pythagoras to a superhuman state; it pictures him majestic and impassive, clothed in robes of white, with a golden coronet around his brows, listening to the music of the spheres, or seeking relaxation in the more humble hymns of Homer, Hesiod, and Thales; lost in the contemplation of Nature, or rapt in ecstasy in his meditations on God; manifesting his descent from Apollo or Hermes by the working of miracles, predicting future events, conversing with genii in the solitude of a dark cavern, and even surpassing the wonder of speaking simultaneously in different tongues, since it was established, by the most indisputable testimony, that he had accomplished the prodigy of being present with and addressing the people in several different places at the same time. It seems not to have occurred to his disciples that such preposterous assertions cannot be sustained by any evidence whatsoever; and that the stronger and clearer such evidence is, instead of supporting the fact for which it is brought forward, it the more serves to shake our confidence in the truth of man, or impresses on us the conclusion that he is easily lead to the adoption of falsehood, and is readily deceived by imposture.
