About half a century before the birth of Plato, Socrates being then in all the impressibility of early manhood, Parmenides, according to the witness of Plato himself—Parmenides at the age of sixty-five—had visited Athens at the great festival of the Panathenaea, in company with Zeno the Eleatic, a characteristic specimen of Greek cleverness, of the acute understanding, personally very attractive. Though forty years old, the reputation this Zeno now enjoyed seems to have been very much the achievement of his youth, and came of a mastery of the sort of paradox youth always delights in. It may be said that no one has ever really answered him; the difficulties with which he played so nicely being really connected with those "antinomies," or contradictions, or inconsistencies, of our thoughts, which more than two thousand years afterwards Kant noted as actually inherent in the mind itself—a certain constitutional weakness or limitation there, in dealing by way of cold-blooded reflexion with the direct presentations of its experience. The "Eleatic Palamedes," Plato calls him, "whose dialectic art causes one and the same thing to appear both like and [29] unlike, one and many, at rest and in motion." Ah! you hear already the sort of words that seem sometimes so barren and unprofitable even in Plato.

It is from extant fragments of a work of his, not a poem, but, appropriately, To Syngramma,+ The Prose, of Zeno, that such knowledge as we have of his doctrine, independently of the Parmenides of Plato, is derived. The active principle of that doctrine then lies in the acuteness with which he unfolds the contradictions which make against the very conceivability of the fundamental phenomena of sense, in so far as those phenomena are supposed to be really existent independently of ourselves. The truth of experience, of a sensible experience, he seems to protest:—Why! sensible experience as such is logically inconceivable. He proved it, or thought, or professed to think, he proved it, in the phenomenon which covers all the most vivid, the seemingly irresistible facts, of such experience. Motion was indeed, as the Heracliteans said, everywhere: was the most incisive of all facts in the realm of supposed sensible fact. Think of the prow of the trireme cleaving the water. For a moment Zeno himself might have seemed but a follower of Heraclitus. He goes beyond him. All is motion: he admits.—Yes: only, motion is (I can show it!) a nonsensical term. Follow it, or rather stay by it, and it transforms itself, agreeably enough for the [30] curious observer, into rest. Motion must be motion in space, of course; from point to point in it,—and again, more closely, from point to point within such interval; and so on, infinitely; 'tis rest there: perpetual motion is perpetual rest:—the hurricane, the falling tower, the deadly arrow from the bow at whose coming you shake there so wretchedly, Zeno's own rapid word-fence—all alike at rest, to the restful eye of the pure reason! The tortoise, the creature that moves most slowly, cannot be overtaken by Achilles, the swiftest of us all; or at least you can give no rational explanation how it comes to be overtaken. Zeno had an armoury of such enigmas. Can a bushel of corn falling make a noise if a single grain makes none? Again, that motion should cease, we find inconceivable: but can you conceive how it should so much as begin? at what point precisely, in the moving body? Ubiquitous, tyrannous, irresistible, as it may seem, motion, with the whole so dazzling world it covers, is— nothing!

Himself so striking an instance of mobile humour in his exposure of the unreality of all movement, Zeno might be taken so far only for a master, or a slave, of paradox; such paradox indeed as is from the very first inherent in every philosophy which (like that of Plato himself, accepting even Zeno as one of its institutors) opposes the seen to the unseen as [31] falsehood to truth. It was the beginning of scholasticism; and the philosophic mind will perhaps never be quite in health, quite sane or natural, again. The objective, unconscious, pleasantly sensuous mind of the Greek, becoming a man, as he thinks, and putting away childish thoughts, is come with Zeno one step towards Aristotle, towards Aquinas, or shall we say into the rude scholasticism of the pedantic Middle Age? And we must have our regrets. There is always something lost in growing up.

The wholesome scepticism of Hume or Mill for instance, the scepticism of the modern world, beset now with insane speculative figments, has been an appeal from the preconceptions of the understanding to the authority of the senses. With the Greeks, whose metaphysic business was then still all to do, the sceptical action of the mind lay rather in the direction of an appeal from the affirmations of sense to the authority of newly-awakened reason. Just then all those real and verbal difficulties which haunt perversely the human mind always, all those unprofitable queries which hang about the notions of matter and time and space, their divisibility and the like, seemed to be stirring together, under the utterance of this brilliant, phenomenally clever, perhaps insolent, young man, his master's favourite. To the work of that grave master, nevertheless—of Parmenides—a very different person certainly from his rattling disciple, Zeno's [32] seemingly so fantastic doctrine was sincerely in service. By its destructive criticism, its dissipation of the very conceivability of the central and most incisive of sensible phenomena, it was a real support to Parmenides in his assertion of the nullity of all that is but phenomenal, leaving open and unoccupied space (emptiness, we might say) to that which really is. That which is, so purely, or absolutely, that it is nothing at all to our mixed powers of apprehension:—Parmenides and the Eleatic School were much occupied with the determination of the thoughts, or of the mere phrases and words, that belong to that.

Motion discredited, motion gone, all was gone that belonged to an outward and concrete experience, thus securing exclusive validity to the sort of knowledge, if knowledge it is to be called, which corresponds to the "Pure Being," that after all is only definable as "Pure Nothing," that colourless, formless, impalpable existence (ousia achrômatos, aschêmatistos, anaphês)+ to use the words of Plato, for whom Parmenides became a sort of inspired voice. Note at times, in reading him, in the closing pages of the fifth book of The Republic for instance, the strange accumulation of terms derivative from the abstract verb "To be." As some more modern metaphysicians have done, even Plato seems to pack such terms together almost by rote. Certainly something of paradox may always be felt even in his [33] exposition of "Being," or perhaps a kind of paralysis of speech—aphasia.+

Parmenides himself had borrowed the thought from another, though he made it his own. Plato, in The Republic, as a critic of Homer, by way of fitting Homer the better for the use of the schoolboys of the ideal city, is ready to sacrifice much of that graceful polytheism in which the Greeks anticipated the dulia of saints and angels in the catholic church. He does this to the advantage of a very abstract, and as it may seem disinterested, certainly an uninteresting, notion of deity, which is in truth:—well! one of the dry sticks of mere "natural theology," as it is called. In this he was but following the first, the original, founder of the Eleatic School, Xenophanes, who in a somewhat scornful spirit had urged on men's attention that, in their prayers and sacrifices to the gods, in all their various thoughts and statements, graceful or hideous, about them, they had only all along with much fallacy been making gods after their own likeness, as horse or dog too, if perchance it cast a glance towards heaven, would after the same manner project thither the likeness of horse or dog: that to think of deity you must think of it as neither here nor there, then nor now; you must away with all limitations of time and space and matter, nay, with the very conditions, the limitation, of thought itself; apparently not [34] observing that to think of it in this way was in reality not to think of it at all:—That in short Being so pure as this is pure Nothing.

In opposition then to the anthropomorphic religious poetry of Homer, Xenophanes elaborates the notion, or rather the abstract or purely verbal definition, of that which really is (to on)+ as inconclusive of all time, and space, and mode; yet so that all which can be identified concretely with mode and space and time is but antithetic to it, as finite to infinite, seeming to being, contingent to necessary, the temporal, in a word, to the eternal. Once for all, in harshest dualism, the only true yet so barren existence is opposed to the world of phenomena—of colour and form and sound and imagination and love, of empirical knowledge. Objects, real objects, as we know, grow in reality towards us in proportion as we define their various qualities. And yet, from another point of view, definition, qualification, is a negative process: it is as if each added quality took from the object we are defining one or more potential qualities. The more definite things become as objects of sensible or other empirical apprehension, the more, it might be said from the logician's point of view, have we denied about them. It might seem that their increasing reality as objects of sense was in direct proportion to the increase of their distance from that perfect Being which is everywhere and at all times in every possible mode of being. A [35] thing visibly white is found as one approaches it to be also smooth to the touch; and this added quality, says the formal logician, does but deprive it of all other possible modes of texture; Omnis determinatio est negatio.+ Vain puerilities! you may exclaim:—with justice. Yet such are the considerations which await the mind that suffers itself to dwell awhile on the abstract formula to which the "rational theology" of Xenophanes leads him. It involved the assertion of an absolute difference between the original and all that is or can be derived from it; that the former annuls, or is exclusive of, the latter, which has in truth no real or legitimate standing-ground as matter of knowledge; that, in opposite yet equally unanswerable senses, at both ends of experience there is— nothing! Of the most concrete object, as of the most abstract, it might be said, that it more properly is not than is.

From Xenophanes, as a critic of the polytheism of the Greek religious poets, that most abstract and arid of formulae, Pure Being, closed in indifferently on every side upon itself, and suspended in the midst of nothing, like a hard transparent crystal ball, as he says; "The Absolute"; "The One"; passed to his fellow-citizen Parmenides, seeking, doubtless in the true spirit of philosophy, for the centre of the universe, of his own experience of it, for some common measure of the experience of all men. To enforce a reasonable unity and order, to impress some larger likeness of reason, [36] as one knows it in one's self, upon the chaotic infinitude of the impressions that reach us from every side, is what all philosophy as such proposes. Kosmos;+ order; reasonable, delightful, order; is a word that became very dear, as we know, to the Greek soul, to what was perhaps most essentially Greek in it, to the Dorian element there. Apollo, the Dorian god, was but its visible consecration. It was what, under his blessing, art superinduced upon the rough stone, the yielding clay, the jarring metallic strings, the common speech of every day. Philosophy, in its turn, with enlarging purpose, would project a similar light of intelligence upon the at first sight somewhat unmeaning world we find actually around us:—project it; or rather discover it, as being really pre-existent there, if one were happy enough to get one's self into the right point of view. To certain fortunate minds the efficacious moment of insight would come, when, with delightful adaptation of means to ends, of the parts to the whole, the entire scene about one, bewildering, unsympathetic, unreasonable, on a superficial view, would put on, for them at least, kosmiotês,+ that so welcome expression of fitness, which it is the business of the fine arts to convey into material things, of the art of discipline to enforce upon the lives of men. The primitive Ionian philosophers had found, or thought they found, such a principle (archê)+ in the force of some omnipresent physical element, [37] air, water, fire; or in some common law, motion, attraction, repulsion; as Plato would find it in an eternally appointed hierarchy of genus and species; as the science of our day embraces it (perhaps after all only in fancy) in the expansion of a large body of observed facts into some all-comprehensive hypothesis, such as "evolution."

For Parmenides, at his early day, himself, as some remnants of his work in that direction bear witness, an acute and curious observer of the concrete and sensible phenomena of nature, that principle of reasonable unity seemed attainable only by a virtual negation, by the obliteration, of all such phenomena. When we have learned as exactly as we can all the curious processes at work in our own bodies or souls, in the stars, in or under the earth, their very definiteness, their limitation, will but make them the more antagonistic to that which alone really is, because it is always and everywhere itself, identical exclusively with itself. Phenomena!—by the force of such arguments as Zeno's, the instructed would make a clean sweep of them, for the establishment, in the resultant void, of the "One," with which it is impossible (para panta legomena)+ in spite of common language, and of what seems common sense, for the "Many"—the hills and cities of Greece, you and me, Parmenides himself, really to co-exist at all. "Parmenides," says one, "had stumbled upon [38] the modern thesis that thought and being are the same."

Something like this—this impossibly abstract doctrine—is what Plato's "father in philosophy" had had to proclaim, in the midst of the busy, brilliant, already complicated life of the recently founded colonial town of Elea. It was like the revelation to Israel in the midst of picturesque idolatries, "The Lord thy God is one Lord";+ only that here it made no claim to touch the affections, or even to warm the imagination. Israel's Greek cousin was to undergo a harder, a more distant and repressive discipline in those matters, to which a peculiarly austere moral beauty, at once self-reliant and submissive, the aesthetic expression of which has a peculiar, an irresistible charm, would in due time correspond.
