History of the Intellectual Development of Europe, Volume I (of 2) / Revised Edition

by John William Draper

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.
