Devoting his attention, then, to the problem of perception—how the mind becomes aware of the existence of external things—he resorted to the hypothesis that they constantly throw off images of themselves, which are assimilated by the air through which they have to pass, and enter the soul by pores in its sensitive organs. Hence such images, being merely of the superficial form, are necessarily imperfect and untrue, and so, therefore, must be the knowledge yielded by them. Democritus rejected the one element of the Eleatics, affirming that there must He introduces the atomic theory. be many; but he did not receive the four of Empedocles, nor his principles of Love and Hate, nor the homœomeriæ of Anaxagoras. He also denied that the primary elements had any sensible qualities whatever. He conceived of all things as being composed of invisible, intangible, and indivisible particles or atoms, which, by reason of variation in their configuration, combination, or position, give rise to the varieties of forms: to the atom he imputed self-existence and eternal duration. His doctrine, therefore, explains how it is that the many can arise from the one, and in this particular he reconciled Destiny, Fate and resistless law. the apparent contradictions of the Ionians and Eleatics. The theory of chemistry, as it now exists, essentially includes his views. The general formative principle of Nature he regarded as being Destiny or Fate; but there are indications that by this he meant nothing more than irreversible law.
A system thus based upon severe mathematical considerations, and taking as its starting-point a vacuum and atoms—the former actionless and passionless; which considers the production of new things as only new aggregations, and the decay of the old as separations; which recognizes in compound bodies specific arrangements of atoms to one another; which can rise to the conception that even a single atom may constitute a world—such a system may commend itself to our attention for its results, but surely not to our approval, when we find it carrying us to the conclusions that even Is led to atheism. mathematical cognition is a mere semblance; that the soul is only a finely-constituted form fitted into the grosser bodily frame; that even for reason itself there is an absolute impossibility of all certainty; that scepticism is to be indulged in to that degree that we may doubt whether, when a cone has been cut asunder, its two surfaces are alike; that the final result of human inquiry is the absolute demonstration that man is incapable of knowledge; that, even if the truth be in his possession, he can never be certain of it; that the world is an illusive phantasm, and that there is no God.
Legends of Democritus.
I need scarcely refer to the legendary stories related of Democritus, as that he put out his eyes with a burning-glass that he might no longer be deluded with their false indications, and more tranquilly exercise his reason—a fiction bearing upon its face the contemptuous accusation of his antagonists, but, by the stolidity of subsequent ages, received as an actual fact instead of a sarcasm. As to his habit of so constantly deriding the knowledge and follies of men that he universally acquired the epithet of the laughing philosopher, we may receive the opinion of the great physician Hippocrates, who being requested by the people of Abdera to cure him of his madness, after long discoursing with him, expressed himself penetrated with admiration, and even with the most profound veneration for him, and rebuked those who had sent him with the remark that they themselves were the more distempered of the two.
Thus far European Greece had done but little in the cause of philosophy. The chief schools were in Asia Minor, or among the Greek colonies of Italy. But the time had now arrived when the mother country was to Rise of philosophy in European Greece. enter upon a distinguished career, though, it must be confessed, from a most unfavourable beginning. This was by no means the only occasion on which the intellectual activity of the Greek colonies made itself felt in the destinies of Europe. The mercantile character in a community has ever been found conducive to mental activity and physical adventure; it holds in light esteem prescriptive opinion, and puts things at the actual value they at the time possess. If the Greek colonies thus discharged the important function of introducing and disseminating speculative philosophy, we shall find them again, five hundred years later, occupied with a similar task on the advent of that period in which philosophical speculation was about to be supplanted by religious faith. For there Commercial communities favourable to new ideas. can be no doubt that, humanly speaking, the cause of the rapid propagation of Christianity, in its first ages, lay in the extraordinary facilities existing among the commercial communities scattered all around the shores of the Mediterranean Sea, from the ports of the Levant to those of France and Spain. An incessant intercourse was kept up among them during the five centuries before Christ; it became, under Roman influence, more and more active, and of increasing political importance. Such a state of things is in the highest degree conducive to the propagation of thought, and, indeed, to its origination, through the constant excitement it furnishes to intellectual activity. Commercial communities, in this respect, present a striking contrast to agricultural. By their aid speculative philosophy was rapidly disseminated everywhere, as was subsequently Christianity. But the agriculturists steadfastly adhered with marvellous stolidity to their ancestral traditions and polytheistic absurdities, until the very designation—paganism—under which their system passes was given as a nickname derived from themselves.
Philosophical influence of the Greek colonies.
The intellectual condition of the Greek colonies of Italy and Sicily has not attracted the attention of critics in the manner it deserves. For, though its political result may appear to those whose attention is fixed by mere material aggrandizement to have been totally eclipsed by the subsequent power of the Roman republic, to one who looks at things in a mere general way it may be a probable inquiry whether the philosophy cultivated in those towns has not, in the course of ages, produced as solid and lasting results as the military achievements of the Eternal City. The relations of the Italian peninsula to the career of European civilization are to be classified under three epochs, the first corresponding to the philosophy generated in the southern Greek towns: this would have attained the elevation long before reached in the advanced systems of India had it not been prevented by the rapid development of Roman power; the second presents the military influence of republican and imperial Rome; to the third belongs the agency of ecclesiastical Rome—for the production of the last we shall find hereafter that the preceding two conspire. The Italian effect upon the whole has therefore been philosophical, material, and mixed. We are greatly in want of a history of the first, for which doubtless many facts still remain to a painstaking and enlightened inquirer.
Origin of the Greek colonial system.
It was on account of her small territory and her numerous population that Greece was obliged to colonize. To these motives must be added internal dissensions, and particularly the consequences of unequal marriages. So numerous did these colonies and their offshoots become, that a great Greek influence pervaded all the Mediterranean shores and many of the most important islands, attention more particularly being paid to the latter, from their supposed strategical value; thus, in the opinion of Alexander the Great, the command of the Mediterranean lay in the possession of Cyprus. The Greek colonists were filibusters; they seized by force the women wherever they settled, but their children were taught to speak the paternal language, as has been the case in more recent times with the descendants of the Spaniards in America. The wealth of some of these Greek colonial towns is said to have been incredible. Crotona was more than twelve miles in circumference; and Sybaris, another of the Italiot cities, was so luxurious and dissipated as even to give rise to a proverb. The prosperity of these places was due to two causes: they were not only the centres of great agricultural districts, but carried on also an active commerce in all directions, the dense population of the mother country offering them a steady and profitable market; they also maintained an active traffic with all the Mediterranean cities; thus, if they furnished Athens with corn, they also furnished Carthage with oil. In the Greek cities connected with this colonial system, especially in Athens, the business of ship-building and navigation was so extensively prosecuted as to give a special character to public life. In other parts of Greece, as in Sparta, it was altogether different. In that state the laws of Lycurgus had abolished private property; all things were held in common; savage life was reduced to a system, and therefore there was no object in commerce. But in Athens, commerce was regarded as being so far from dishonourable that some of the most illustrious men, whose names have descended to us as philosophers, were occupied with mercantile pursuits. Aristotle kept a druggist's shop in Athens, and Plato sold oil in Egypt.
It was the intention of Athens, had she succeeded in the conquest of Sicily, to make an attempt upon Carthage, foreseeing therein the dominion of the Mediterranean, as was actually realized subsequently by Rome. The destruction of that city constituted the point of ascendancy in the history of the Great Republic. Carthage stood upon a peninsula forty-five miles round, with a neck only three miles across. Her territory has been estimated as having a sea-line of not less than 1400 miles, and containing 300 towns; she had also possessions in Spain, in Sicily, and other Mediterranean islands, acquired, not by conquest, but by colonization. In the silver mines of Spain she employed not less than forty thousand men. In these respects she was guided by the maxims of her Phœnician ancestry, for the Tyrians had colonized for depôts, and had forty stations of that kind in the Mediterranean. Indeed, Carthage herself originated in that way, owing her development to the position she held at the junction of the east and west basins. The Carthaginian merchants did not carry for hire, but dealt in their Carthaginian supremacy in the Mediterranean. commodities. This implied an extensive system of depôts and bonding. They had anticipated many of the devices of modern commerce. They effected insurances, made loans on bottomry, and it has been supposed that their leathern money may have been of the nature of our bank notes.
