Yet Heraclitus, thus superbly turning aside from the vulgar to think, so early in the impetuous spring-tide of Greek history, does but reflect after all the aspect of what actually surrounds him, when he cries out--his philosophy was no matter of formal treatise or system, but of harsh, protesting cries--Panta chôrei kai ouden menei.+ All things give way: nothing remaineth. There had been enquirers before him of another sort, purely physical enquirers, whose bold, contradictory, seemingly impious guesses how and of what primary elements the world of visible things, the sun, the stars, the brutes, their own souls and bodies, had been composed, were themselves a part of the bold enterprise of that romantic age; a series of intellectual adventures, of a piece with its adventures in unknown lands or upon the sea. The resultant intellectual chaos expressed the very spirit of gifted and sanguine but insubordinate youth (remember, that the word neotês,+ youth, came to mean rashness, insolence!) questioning, deciding, rejecting, on mere rags and tatters of evidence, unbent to discipline, unmethodical, irresponsible. Those opinions too, coming and going, those conjectures as to what under-lay the sensible world, were themselves but fluid elements on the changing surface of existence. [15] Surface, we say; but was there really anything beneath it? That was what to the majority of his hearers, his readers, Heraclitus, with an eye perhaps on practice, seemed to deny. Perpetual motion, alike in things and in men's thoughts about them,--the sad, self-conscious, philosophy of Heraclitus, like one, knowing beyond his years, in this barely adolescent world which he is so eager to instruct, makes no pretence to be able to restrain that. Was not the very essence of thought itself also such perpetual motion? a baffling transition from the dead past, alive one moment since, to a present, itself deceased in turn ere we can say, It is here? A keen analyst of the facts of nature and mind, a master presumably of all the knowledge that then there was, a vigorous definer of thoughts, he does but refer the superficial movement of all persons and things around him to deeper and still more masterful currents of universal change, stealthily withdrawing the apparently solid earth itself from beneath one's feet. The principle of disintegration, the incoherency of fire or flood (for Heraclitus these are but very lively instances of movements, subtler yet more wasteful still) are inherent in the primary elements alike of matter and of the soul. Legei pou Hêrakleitos, says Socrates in the Cratylus, hoti panta chôrei kai ouden menei.+ But the principle of lapse, of waste, was, in fact, in one's self. "No one has ever passed [16] twice over the same stream." Nay, the passenger himself is without identity. Upon the same stream at the same moment we do, and do not, embark: for we are, and are not: eimen te kai ouk eimen.+ And this rapid change, if
