When the power and value of these primitive speculations can no longer be denied, their originality is sometimes questioned by the systematic detractors of everything Hellenic. Thales and the rest, we are told, simply borrowed their theories without acknowledgment from a storehouse of Oriental wisdom on which the Greeks are supposed to have drawn as freely as Coleridge drew on German philosophy. Sometimes each system is affiliated to one of the great Asiatic religions; sometimes they are all traced back to the schools of Hindostan. It is natural that no two critics should agree, when the rival explanations are based on nothing stronger than superficial analogies and accidental coincidences. Dr. Zeller in his wonderfully learned, clear, and sagacious work on Greek philosophy, has carefully sifted some of the hypotheses referred to, and shown how destitute they are of internal or external evidence, and how utterly they fail to account for the facts. The oldest and best authorities, Plato and Aristotle, knew nothing about such a derivation of Greek thought from Eastern sources. Isocrates does, indeed, mention that Pythagoras borrowed his philosophy from Egypt, but Isocrates did not even pretend to be a truthful narrator. No Greek of the early period except those regularly domiciled in Susa seems to have been acquainted with any language but his own. Few travelled very far into Asia, and of those few, only one or two were philosophers. Democritus, who visited more foreign countries than any man of his time, speaks only of having discussed mathematical problems with the wise men whom he encountered; and even in mathematics he was at least their equal.9 It was precisely at the greatest distance from Asia, in Italy and Sicily, that the systems arose which seem to have most analogy with Asiatic modes of thought. Can we suppose that the traders of those times were in any way qualified to transport the speculations of Confucius and the Vedas to such a distance from their native homes? With far better reason might one expect a German merchant to carry a knowledge of Kant’s philosophy from Königsberg to Canton. But a more convincing argument than any is to show that Greek philosophy in its historical evolution exhibits a perfectly natural and spontaneous progress from simpler to more complex forms, and that system grew out of system by a strictly logical process of extension, analysis, and combination. This is what, chiefly under the guidance of Zeller, we shall now attempt to do.
II.
Thales, of Miletus, an Ionian geometrician and astronomer, about whose age considerable uncertainty prevails, but who seems to have flourished towards the close of the seventh century before our era, is by general consent regarded as the father of Greek physical philosophy. Others before him had attempted to account for the world’s origin, but none like him had traced it back to a purely natural beginning. According to Thales all things have come from water. That the earth is entirely enclosed by water above and below as well as all round was perhaps a common notion among the Western Asiatics. It was certainly believed by the Hebrews, as we learn from the accounts of the creation and the flood contained in Genesis. The Milesian thinker showed his originality by generalising still further and declaring that not only did water surround all things, but that all things were derived from it as their first cause and substance, that water was, so to speak, the material absolute. Never have more pregnant words been spoken; they acted like a ferment on the Greek mind; they were the grain whence grew a tree that has overshadowed the whole earth. At one stroke they substituted a comparatively scientific, because a verifiable principle for the confused fancies of mythologising poets. Not that Thales was an atheist, or an agnostic, or anything of that sort. On the contrary, he is reported to have said that all things were full of gods; and the report sounds credible enough. Most probably the saying was a protest against the popular limitation of divine agencies to certain special occasions and favoured localities. A true thinker seeks above all for consistency and continuity. He will more readily accept a perpetual stream of creative energy than a series of arbitrary and isolated interferences with the course of Nature. For the rest, Thales made no attempt to explain how water came to be transformed into other substances, nor is it likely that the necessity of such an explanation had ever occurred to him. We may suspect that he and others after him were not capable of distinguishing very clearly between such notions as space, time, cause, substance, and limit. It is almost as difficult for us to enter into the thoughts of these primitive philosophers as it would have been for them to comprehend processes of reasoning already familiar to Plato and Aristotle. Possibly the forms under which we arrange our conceptions may become equally obsolete at a more advanced stage of intellectual evolution, and our sharp distinctions may prove to be not less artificial than the confused identifications which they have superseded.
The next great forward step in speculation was taken by Anaximander, another Milesian, also of distinguished attainments in mathematics and astronomy. We have seen that to Thales water, the all-embracing element, became, as such, the first cause of all things, the absolute principle of existence. His successor adopted the same general point of view, but looked out from it with a more penetrating gaze. Beyond water lay something else which he called the Infinite. He did not mean the empty abstraction which has stalked about in modern times under that ill-omened name, nor yet did he mean infinite space, but something richer and more concrete than either; a storehouse of materials whence the waste of existence could be perpetually made good. The growth and decay of individual forms involve a ceaseless drain on Nature, and the deficiency must be supplied by a corresponding influx from without.A For, be it observed that, although the Greek thinkers were at this period well aware that nothing can come from nothing, they had not yet grasped the complementary truth inalienably wedded to it by Lucretius in one immortal couplet, that nothing can return to nothing; and Kant is quite mistaken when he treats the two as historically inseparable. Common experience forces the one on our attention much sooner than the other. Our incomings are very strictly measured out and accounted for without difficulty, while it is hard to tell what becomes of all our expenditure, physical and economical. Yet, although the indestructibility of matter was a conception which had not yet dawned on Anaximander, he seems to have been feeling his way towards the recognition of a circulatory movement pervading all Nature. Everything, he says, must at last be reabsorbed in the Infinite as a punishment for the sin of its separate existence.10 Some may find in this sentiment a note of Oriental mysticism. Rather does its very sadness illustrate the healthy vitality of Greek feeling, to which absorption seemed like the punishment of a crime against the absolute, and not, as to so many Asiatics, the crown and consummation of spiritual perfection. Be this as it may, a doctrine which identified the death of the whole world with its reabsorption into a higher reality would soon suggest the idea that its component parts vanish only to reappear in new combinations.
Anaximander’s system was succeeded by a number of others which cannot be arranged according to any order of linear progression. Such arrangements are, indeed, false in principle. Intellectual life, like every other life, is a product of manifold conditions, and their varied combinations are certain to issue in a corresponding multiplicity of effects. Anaximenes, a fellow-townsman of Anaximander, followed most closely in the footsteps of the master. Attempting, as it would appear, to mediate between his two predecessors, he chose air for a primal element. Air is more omnipresent than water, which, as well as earth, is enclosed within its plastic sphere. On the other hand, it is more tangible and concrete than the Infinite, or may even be substituted for that conception by supposing it to extend as far as thought can reach. As before, cosmogony grows out of cosmography; the enclosing element is the parent of those embraced within it.
