It was in this active, prosperous, enterprising state, and at the period of its highest activity, that Thales, statesman, practical engineer, mathematician, philosopher, flourished. Without attempting to fix his date too closely, we may take it that he was a leading man in Miletus for the greater part of the {3} first half of the sixth century before Christ. We hear of an eclipse predicted by him, of the course of a river usefully changed, of shrewd and profitable handling of the market, of wise advice in the general councils of the league. He seems to have been at once a student of mathematics and an observer of nature, and withal something having analogy with both, an inquirer or speculator into the origin of things. To us nowadays this suggests a student of geology, or physiography, or some such branch of physical science; to Thales it probably rather suggested a theoretical inquiry into the simplest thinkable aspect of things as existing. "Under what form known to us," he would seem to have asked, "may we assume an identity in all known things, so as best to cover or render explicable the things as we know them?" The 'beginning' of things (for it was thus he described this assumed identity) was not conceived by him as something which was long ages before, and which had ceased to be; rather it meant the reality of things now. Thales then was the putter of a question, which had not been asked expressly before, but which has never ceased to be asked since. He was also the formulator of a new meaning for a word; the word 'beginning' ((Greek) arche) got the meaning of 'underlying reality' and so of 'ending' as well. In short, he so dealt with a word, on the surface of it implying {4} time, as to eliminate the idea of time, and suggest a method of looking at the world, more profound and far-reaching than had been before imagined.[1]
It is interesting to find that the man who was thus the first philosopher, the first observer who took a metaphysical, non-temporal, analytical view of the world, and so became the predecessor of all those votaries of 'other-world' ways of thinking,—whether as academic idealist, or 'budge doctor of the Stoic fur,' or Christian ascetic or what not, whose ways are such a puzzle to the 'hard-headed practical man,'—was himself one of the shrewdest men of his day, so shrewd that by common consent he was placed foremost in antiquity among the Seven Sages, or seven shrewd men, whose practical wisdom became a world's tradition, enshrined in anecdote and crystallised in proverb.

The chief record that we possess of the philosophic teaching of Thales is contained in an interesting notice of earlier philosophies by Aristotle, the main part of which as regards Thales runs as follows:
"The early philosophers as a rule formulated the originative principle ((Greek) arche) of all things under some material expression. By the originative principle or element of things they meant that of which all {5} existing things are composed, that which determines their coming into being, and into which they pass on ceasing to be. Where these philosophers differed from each other was simply in the answer which they gave to the question what was the nature of this principle, the differences of view among them applying both to the number, and to the character, of the supposed element or elements.
"Thales, the pioneer of this philosophy, maintained that Water was the originative principle of all things. It was doubtless in this sense that he said that the earth rested on water. What suggested the conception to him may have been such facts of observation, as that all forms of substance which promote life are moist, that heat itself seems to be conditioned by moisture, that the life-producing seed in all creatures is moist, and so on."
Other characteristics of water, it is elsewhere suggested, may have been in Thales' mind, such as its readiness to take various shapes, its convertibility from water into vapour or ice, its ready mixture with other substances, and so forth. What we have chiefly to note is, that the more unscientific this theory about the universe may strike us as being, the more completely out of accord with facts now familiar to everybody, the more striking is it as marking a new mood of mind, in which unity, though only very partially suggested or discoverable by the senses, is {6} preferred to that infinite and indefinite variety and difference which the senses give us at every moment. There is here the germ of a new aspiration, of a determination not to rest in the merely momentary and different, but at least to try, even against the apparent evidence of the senses, for something more permanently intelligible. As a first suggestion of what this permanent underlying reality may be, Water might very well pass. It is probable that even to Thales himself it was only a symbol, like the figure in a mathematical proposition, representing by the first passable physical phenomenon which came to hand, that ideal reality underlying all change, which is at once the beginning, the middle, and the end of all. That he did not mean Water, in the ordinary prosaic sense, to be identical with this, is suggested by some [10] other sayings of his. "Thales," says Aristotle elsewhere, "thought the whole universe was full of gods." "All things," he is recorded as saying, "have a soul in them, in virtue of which they move other things, and are themselves moved, even as the magnet, by virtue of its life or soul, moves the iron." Without pushing these fragmentary utterances too far, we may well conclude that whether Thales spoke of the soul of the universe and its divine indwelling powers, or gods, or of water as the origin of things, he was only vaguely symbolising in different ways an idea as yet formless and void, like the primeval chaos, but nevertheless, {7} like it, containing within it a promise and a potency of greater life hereafter.
II. ANAXIMANDER.—Our information with respect to thinkers so remote as these men is too scanty and too fragmentary, to enable us to say in what manner or degree they influenced each other. We cannot say for certain that any one of them was pupil or antagonist of another. They appear each of them, one might say for a moment only, from amidst the darkness of antiquity; a few sayings of theirs we catch vaguely across the void, and then they disappear. There is not, consequently, any very distinct progression or continuity observable among them, and so far therefore one has to confess that the title 'School of Miletus' is a misnomer. We have already quoted the words of Aristotle in which he classes the Ionic philosophers together, as all of them giving a material aspect of some kind to the originative principle of the universe (see above, P. 4). But while this is a characteristic observable in some of them, it is not so obviously discoverable in the second of their number, Anaximander.
This philosopher is said to have been younger by [11] one generation than Thales, but to have been intimate with him. He, like Thales, was a native of Miletus, and while we do not hear of him as a person, like Thales, of political eminence and activity, he was certainly the equal, if not the superior, of Thales in {8} mathematical and scientific ability. He is said to have either invented or at least made known to Greece the construction of the sun-dial. He was associated with Hecataeus in the construction of the earliest geographical charts or maps; he devoted himself with some success to the science of astronomy. His familiarity with the abstractions of mathematics perhaps accounts for the more abstract form, in which he expressed his idea of the principle of all things.
