THALES

In an earlier chapter mention was made of that truly remarkable group of thinkers who, in the sixth century before the Christian era, made the momentous transition from mythology and tradition to philosophy and science. It was also pointed out that these pioneers, bold as they were, could not shake themselves free from the social and intellectual conditions of their day. And it is precisely this fact of what may be termed contemporary limitations that makes a review of their speculations so valuable to a student of Nature Mysticism. For they lived in times when the old spontaneous nature beliefs were yielding to reflective criticism. Their philosophising took its spring from the fittest products of the mytho-poeic faculty, and thus remained in living contact with the primitive past, while reaching forward, in the spirit of the future, to an ordered knowledge of an ordered whole. The chief object of their search was the Welt-stoff—the substance of the universe—and they were guided in their search by the dominating concepts which had emerged in the long course of the animistic and mythological stages. Certain forms of external existence have impressed themselves upon the general mind, notably those of water, air, and fire; and to these the reflecting mind naturally turned in its earliest efforts to discover the Ground of things. The interest taken by the nature-mystic in this group of thinkers is twofold. Firstly, he finds that in their speculations there is a large element of primitive intuition, embodied in concepts fashioned by the spontaneous play of reflective thought and free imagination. Closeness to nature is thus secured. And secondly, he rejoices in the fact that these speculations, crude and premature as they inevitably were, contained germs of thought and flashes of insight which anticipate the most advanced speculative science and philosophy of the present day. He maintains that here is corroboration of his view of intuition. Nature was the teacher—and it was to intuition that she chiefly addressed herself; and the intellect—keen and fresh, but untrained—was able to seize upon the material presented, and to fix it in concepts and theories which share in nature's universal and unending life.

Water, air, and fire—what an enormous number and variety of natural phenomena range themselves under these heads! If we try to understand why they were singled out in turn, in the search for the Welt-stoff, we shall have penetrated far into the Nature Mysticism of these famous "elements."

Starting, then, with Thales, we ask why he fixed upon water in his attempt (the earliest recorded) to determine the constitution of the universe? What were the properties, qualities, and functions of that "element" which arrested his attention, and governed his crude, but acute and original, speculations? As already remarked, existing cosmological conceptions played an important rôle, more especially that of the great primeval ocean on which the world was supposed to float. This cosmographical ocean and its accompanying myths will be considered in a subsequent chapter. But restricting our view at present to the physical aspects of water, it is not wholly impossible to recover, and sympathise with, his train of reasoning.

Water is wonderfully mobile, incessantly changing, impelled apparently by some inherent principle of movement. Its volatility, also, is very marked; it passes from solid to liquid, and liquid to vapour, and easily reverses the series. More especially would the old-world thinker be struck by the phenomena of the circulation of water. He would see the vapour drawn up by the sun from lake and ocean, seeming to feed the heavenly fires, and returning to earth in the form of rain. He concluded that this must represent the flow of the cosmic process as a whole. Again, in the falling of dew, in the gatherings of mists, and in the welling-up of fountains, the solid materials of the world are apparently passing into a liquid state.

Thales was not the first to note these things. They had been subtly modifying the thoughts of men for untold generations. But he was the first whom we know to have gathered together into a definite theory the vague intuitions which had been so long unconsciously operative. He singled out this mobile element and saw in it the substance of the flux of the world as a whole.

His theory of movement took a wide range. He did not separate the thing moved from the moving force; nor did he draw any distinction between the organic and inorganic—the mechanical and the vital. He regarded all modes of motion as essentially spontaneous and self-determined. Moreover (as Aristotle tells us) he identified this inherent principle of change with what is divine in nature and in the soul. That is to say, the Real, for Thales, is living impulse and continuous process. It is experienced in man's conscious activities, and constitutes the principle of unity in every mode and form of existence.

It is on the organic side of this speculation that Aristotle, probably biased by his biological studies, chiefly dwells. Is it possible to trace the grounds of which Thales based his wider induction? Aristotle helps us. He supposes his predecessor to have noted that water and life seem to be inseparable, and that moisture is necessary to the germination and development of all known organisms. It was natural to conclude that the principle of life is in the water—the conclusion of the reason also harmonising with the intuition stimulated by movement. Nor was the inference altogether unwarranted. Put into historical perspective, it still retains its force and value. The latest biological authorities tell us that all branches of the zoological family tree were formed on the moist shores of large water basins, and that there is no form of life, not only terrestrial, but even of the deep seas which has not passed through a littoral phase. In other words, it is still allowable to hold that the "moist," as Thales generally called his primal element, contains one of the secrets of life. So close is the earliest to the latest pronouncement on the origin of life on the globe!

Reviewing this brief exposition of the leading doctrine of an ancient speculation, what bearing has it on the principles of Nature Mysticism as laid down in preceding chapters? Certain fairly obvious ones. Thales was guided by impressions received from the qualities, behaviour, and functions of water; and they led him to attribute a plastic life to matter. It would be modernising him too severely to style him a hylozoist. But his ascription of a soul to the magnet and to amber carries him far on the way to that metaphysical world-view. Deeply suggestive also is the saying which, if not rightly attributed to him, is at least characteristic of his school—"All things are full of the gods." We may therefore infer that the physical properties of water are such as to suggest the ideas which have culminated in modern animism. That is to say, water is capable of producing intellectual and spiritual, as well as what are termed physical effects. The deeper view of intuition is justified. And Thales, by virtue of the whole trend and outcome of his speculations, may claim an honoured place in the ranks of the nature-mystics.
