Платон - Sophist

The Idealism of the fourth century before Christ in Greece, as in other ages and countries, seems to have provoked a reaction towards Materialism. The maintainers of this doctrine are described in the Theaetetus as obstinate persons who will believe in nothing which they cannot hold in their hands, and in the Sophist as incapable of argument. They are probably the same who are said in the Tenth Book of the Laws to attribute the course of events to nature, art, and chance. Who they were, we have no means of determining except from Plato's description of them. His silence respecting the Atomists might lead us to suppose that here we have a trace of them. But the Atomists were not Materialists in the grosser sense of the term, nor were they incapable of reasoning; and Plato would hardly have described a great genius like Democritus in the disdainful terms which he uses of the Materialists. Upon the whole, we must infer that the persons here spoken of are unknown to us, like the many other writers and talkers at Athens and elsewhere, of whose endless activity of mind Aristotle in his Metaphysics has preserved an anonymous memorial.

V. The Sophist is the sequel of the Theaetetus, and is connected with the Parmenides by a direct allusion (compare Introductions to Theaetetus and Parmenides). In the Theaetetus we sought to discover the nature of knowledge and false opinion. But the nature of false opinion seemed impenetrable; for we were unable to understand how there could be any reality in Not-being. In the Sophist the question is taken up again; the nature of Not-being is detected, and there is no longer any metaphysical impediment in the way of admitting the possibility of falsehood. To the Parmenides, the Sophist stands in a less defined and more remote relation. There human thought is in process of disorganization; no absurdity or inconsistency is too great to be elicited from the analysis of the simple ideas of Unity or Being. In the Sophist the same contradictions are pursued to a certain extent, but only with a view to their resolution. The aim of the dialogue is to show how the few elemental conceptions of the human mind admit of a natural connexion in thought and speech, which Megarian or other sophistry vainly attempts to deny.

…

True to the appointment of the previous day, Theodorus and Theaetetus meet Socrates at the same spot, bringing with them an Eleatic Stranger, whom Theodorus introduces as a true philosopher. Socrates, half in jest, half in earnest, declares that he must be a god in disguise, who, as Homer would say, has come to earth that he may visit the good and evil among men, and detect the foolishness of Athenian wisdom. At any rate he is a divine person, one of a class who are hardly recognized on earth; who appear in divers forms – now as statesmen, now as sophists, and are often deemed madmen. 'Philosopher, statesman, sophist,' says Socrates, repeating the words – 'I should like to ask our Eleatic friend what his countrymen think of them; do they regard them as one, or three?'

The Stranger has been already asked the same question by Theodorus and Theaetetus; and he at once replies that they are thought to be three; but to explain the difference fully would take time. He is pressed to give this fuller explanation, either in the form of a speech or of question and answer. He prefers the latter, and chooses as his respondent Theaetetus, whom he already knows, and who is recommended to him by Socrates.

We are agreed, he says, about the name Sophist, but we may not be equally agreed about his nature. Great subjects should be approached through familiar examples, and, considering that he is a creature not easily caught, I think that, before approaching him, we should try our hand upon some more obvious animal, who may be made the subject of logical experiment; shall we say an angler? 'Very good.'

In the first place, the angler is an artist; and there are two kinds of art, – productive art, which includes husbandry, manufactures, imitations; and acquisitive art, which includes learning, trading, fighting, hunting. The angler's is an acquisitive art, and acquisition may be effected either by exchange or by conquest; in the latter case, either by force or craft. Conquest by craft is called hunting, and of hunting there is one kind which pursues inanimate, and another which pursues animate objects; and animate objects may be either land animals or water animals, and water animals either fly over the water or live in the water. The hunting of the last is called fishing; and of fishing, one kind uses enclosures, catching the fish in nets and baskets, and another kind strikes them either with spears by night or with barbed spears or barbed hooks by day; the barbed spears are impelled from above, the barbed hooks are jerked into the head and lips of the fish, which are then drawn from below upwards. Thus, by a series of divisions, we have arrived at the definition of the angler's art.

And now by the help of this example we may proceed to bring to light the nature of the Sophist. Like the angler, he is an artist, and the resemblance does not end here. For they are both hunters, and hunters of animals; the one of water, and the other of land animals. But at this point they diverge, the one going to the sea and the rivers, and the other to the rivers of wealth and rich meadow-lands, in which generous youth abide. On land you may hunt tame animals, or you may hunt wild animals. And man is a tame animal, and he may be hunted either by force or persuasion; – either by the pirate, man-stealer, soldier, or by the lawyer, orator, talker. The latter use persuasion, and persuasion is either private or public. Of the private practitioners of the art, some bring gifts to those whom they hunt: these are lovers. And others take hire; and some of these flatter, and in return are fed; others profess to teach virtue and receive a round sum. And who are these last? Tell me who? Have we not unearthed the Sophist?

But he is a many-sided creature, and may still be traced in another line of descent. The acquisitive art had a branch of exchange as well as of hunting, and exchange is either giving or selling; and the seller is either a manufacturer or a merchant; and the merchant either retails or exports; and the exporter may export either food for the body or food for the mind. And of this trading in food for the mind, one kind may be termed the art of display, and another the art of selling learning; and learning may be a learning of the arts or of virtue. The seller of the arts may be called an art-seller; the seller of virtue, a Sophist.

Again, there is a third line, in which a Sophist may be traced. For is he less a Sophist when, instead of exporting his wares to another country, he stays at home, and retails goods, which he not only buys of others, but manufactures himself?

Or he may be descended from the acquisitive art in the combative line, through the pugnacious, the controversial, the disputatious arts; and he will be found at last in the eristic section of the latter, and in that division of it which disputes in private for gain about the general principles of right and wrong.

And still there is a track of him which has not yet been followed out by us. Do not our household servants talk of sifting, straining, winnowing? And they also speak of carding, spinning, and the like. All these are processes of division; and of division there are two kinds, – one in which like is divided from like, and another in which the good is separated from the bad. The latter of the two is termed purification; and again, of purification, there are two sorts, – of animate bodies (which may be internal or external), and of inanimate. Medicine and gymnastic are the internal purifications of the animate, and bathing the external; and of the inanimate, fulling and cleaning and other humble processes, some of which have ludicrous names. Not that dialectic is a respecter of names or persons, or a despiser of humble occupations; nor does she think much of the greater or less benefits conferred by them. For her aim is knowledge; she wants to know how the arts are related to one another, and would quite as soon learn the nature of hunting from the vermin-destroyer as from the general. And she only desires to have a general name, which shall distinguish purifications of the soul from purifications of the body.
