IV. HERACLITUS.--Although not a native of Miletus, but of Ephesus, Heraclitus, both by his nationality as an Ionian and by his position in the development of philosophic conceptions, falls naturally to be classed with the philosophers of Miletus. His period may be given approximately as from about 560 to 500 B.C., though others place him a generation later. Few authentic particulars have been preserved of him. We hear of extensive travels, of his return to his native city only to refuse a share in its activities, of his retirement to a hermit's life. He seems to have formed a contrast to the preceding philosophers in his greater detachment from the ordinary interests of civic existence; and much in his teaching suggests the ascetic if not the misanthrope. He received the nickname of 'The Obscure,' from the studied mystery in which he was supposed to involve his {16} [23] teaching. He wrote not for the vulgar, but for the gifted few. 'Much learning makes not wise' was the motto of his work; the man of gift, of insight, that man is better than ten thousand. He was savage in his criticism of other writers, even the greatest. Homer, he said, and Archilochus too, deserved to be hooted from the platform and thrashed. Even the main purport of his writings was differently interpreted. Some named his work 'The Muses,' as though it were chiefly a poetic vision; others named it 'The sure Steersman to the Goal of Life'; others, more prosaically, 'A Treatise of Nature.' [26] The fundamental principle or fact of being Heraclitus formulated in the famous dictum, 'All things pass.' In the eternal flux or flow of being consisted its reality; even as in a river the water is ever changing, and the river exists as a river only in virtue of this continual change; or as in a living body, wherein while there is life there is no stability or fixedness; stability and fixedness are the attributes of the unreal image of life, not of life itself. Thus, as will be observed, from the _material_ basis of being as conceived by Thales, with only a very vague conception of the counter-principle of movement, philosophy has wheeled round in Heraclitus to the other extreme; he finds his permanent element in the negation of permanence; being or reality consists in never 'being' but always 'becoming,' not in stability but in change. {17} [27] This eternal movement he pictures elsewhere as an eternal strife of opposites, whose differences nevertheless consummate themselves in finest harmony. Thus oneness emerges out of multiplicity, multiplicity out of oneness; and the harmony of the universe is of contraries, as of the lyre and the bow. _War_ is the father and king and lord of all things. Neither god nor man presided at the creation of anything that is; that which was, is that which is, and that which ever shall be; even an ever-living Fire, ever kindling and ever being extinguished.
