Sophist

Now purification is the taking away of evil; and there are two kinds of evil in the soul, – the one answering to disease in the body, and the other to deformity. Disease is the discord or war of opposite principles in the soul; and deformity is the want of symmetry, or failure in the attainment of a mark or measure. The latter arises from ignorance, and no one is voluntarily ignorant; ignorance is only the aberration of the soul moving towards knowledge. And as medicine cures the diseases and gymnastic the deformity of the body, so correction cures the injustice, and education (which differs among the Hellenes from mere instruction in the arts) cures the ignorance of the soul. Again, ignorance is twofold, simple ignorance, and ignorance having the conceit of knowledge. And education is also twofold: there is the old-fashioned moral training of our forefathers, which was very troublesome and not very successful; and another, of a more subtle nature, which proceeds upon a notion that all ignorance is involuntary. The latter convicts a man out of his own mouth, by pointing out to him his inconsistencies and contradictions; and the consequence is that he quarrels with himself, instead of quarrelling with his neighbours, and is cured of prejudices and obstructions by a mode of treatment which is equally entertaining and effectual. The physician of the soul is aware that his patient will receive no nourishment unless he has been cleaned out; and the soul of the Great King himself, if he has not undergone this purification, is unclean and impure.

And who are the ministers of the purification? Sophists I may not call them. Yet they bear about the same likeness to Sophists as the dog, who is the gentlest of animals, does to the wolf, who is the fiercest. Comparisons are slippery things; but for the present let us assume the resemblance of the two, which may probably be disallowed hereafter. And so, from division comes purification; and from this, mental purification; and from mental purification, instruction; and from instruction, education; and from education, the nobly-descended art of Sophistry, which is engaged in the detection of conceit. I do not however think that we have yet found the Sophist, or that his will ultimately prove to be the desired art of education; but neither do I think that he can long escape me, for every way is blocked. Before we make the final assault, let us take breath, and reckon up the many forms which he has assumed: (1) he was the paid hunter of wealth and birth; (2) he was the trader in the goods of the soul; (3) he was the retailer of them; (4) he was the manufacturer of his own learned wares; (5) he was the disputant; and (6) he was the purger away of prejudices – although this latter point is admitted to be doubtful.

Now, there must surely be something wrong in the professor of any art having so many names and kinds of knowledge. Does not the very number of them imply that the nature of his art is not understood? And that we may not be involved in the misunderstanding, let us observe which of his characteristics is the most prominent. Above all things he is a disputant. He will dispute and teach others to dispute about things visible and invisible – about man, about the gods, about politics, about law, about wrestling, about all things. But can he know all things? 'He cannot.' How then can he dispute satisfactorily with any one who knows? 'Impossible.' Then what is the trick of his art, and why does he receive money from his admirers? 'Because he is believed by them to know all things.' You mean to say that he seems to have a knowledge of them? 'Yes.'

Suppose a person were to say, not that he would dispute about all things, but that he would make all things, you and me, and all other creatures, the earth and the heavens and the gods, and would sell them all for a few pence – this would be a great jest; but not greater than if he said that he knew all things, and could teach them in a short time, and at a small cost. For all imitation is a jest, and the most graceful form of jest. Now the painter is a man who professes to make all things, and children, who see his pictures at a distance, sometimes take them for realities: and the Sophist pretends to know all things, and he, too, can deceive young men, who are still at a distance from the truth, not through their eyes, but through their ears, by the mummery of words, and induce them to believe him. But as they grow older, and come into contact with realities, they learn by experience the futility of his pretensions. The Sophist, then, has not real knowledge; he is only an imitator, or image-maker.

And now, having got him in a corner of the dialectical net, let us divide and subdivide until we catch him. Of image-making there are two kinds, – the art of making likenesses, and the art of making appearances. The latter may be illustrated by sculpture and painting, which often use illusions, and alter the proportions of figures, in order to adapt their works to the eye. And the Sophist also uses illusions, and his imitations are apparent and not real. But how can anything be an appearance only? Here arises a difficulty which has always beset the subject of appearances. For the argument is asserting the existence of not-being. And this is what the great Parmenides was all his life denying in prose and also in verse. 'You will never find,' he says, 'that not-being is.' And the words prove themselves! Not-being cannot be attributed to any being; for how can any being be wholly abstracted from being? Again, in every predication there is an attribution of singular or plural. But number is the most real of all things, and cannot be attributed to not-being. Therefore not-being cannot be predicated or expressed; for how can we say 'is,' 'are not,' without number?

And now arises the greatest difficulty of all. If not-being is inconceivable, how can not-being be refuted? And am I not contradicting myself at this moment, in speaking either in the singular or the plural of that to which I deny both plurality and unity? You, Theaetetus, have the might of youth, and I conjure you to exert yourself, and, if you can, to find an expression for not-being which does not imply being and number. 'But I cannot.' Then the Sophist must be left in his hole. We may call him an image-maker if we please, but he will only say, 'And pray, what is an image?' And we shall reply, 'A reflection in the water, or in a mirror'; and he will say, 'Let us shut our eyes and open our minds; what is the common notion of all images?' 'I should answer, Such another, made in the likeness of the true.' Real or not real? 'Not real; at least, not in a true sense.' And the real 'is,' and the not-real 'is not'? 'Yes.' Then a likeness is really unreal, and essentially not. Here is a pretty complication of being and not-being, in which the many-headed Sophist has entangled us. He will at once point out that he is compelling us to contradict ourselves, by affirming being of not-being. I think that we must cease to look for him in the class of imitators.

But ought we to give him up? 'I should say, certainly not.' Then I fear that I must lay hands on my father Parmenides; but do not call me a parricide; for there is no way out of the difficulty except to show that in some sense not-being is; and if this is not admitted, no one can speak of falsehood, or false opinion, or imitation, without falling into a contradiction. You observe how unwilling I am to undertake the task; for I know that I am exposing myself to the charge of inconsistency in asserting the being of not-being. But if I am to make the attempt, I think that I had better begin at the beginning.

Lightly in the days of our youth, Parmenides and others told us tales about the origin of the universe: one spoke of three principles warring and at peace again, marrying and begetting children; another of two principles, hot and cold, dry and moist, which also formed relationships. There were the Eleatics in our part of the world, saying that all things are one; whose doctrine begins with Xenophanes, and is even older. Ionian, and, more recently, Sicilian muses speak of a one and many which are held together by enmity and friendship, ever parting, ever meeting. Some of them do not insist on the perpetual strife, but adopt a gentler strain, and speak of alternation only. Whether they are right or not, who can say? But one thing we can say – that they went on their way without much caring whether we understood them or not. For tell me, Theaetetus, do you understand what they mean by their assertion of unity, or by their combinations and separations of two or more principles? I used to think, when I was young, that I knew all about not-being, and now I am in great difficulties even about being.

Let us proceed first to the examination of being. Turning to the dualist philosophers, we say to them: Is being a third element besides hot and cold? or do you identify one or both of the two elements with being? At any rate, you can hardly avoid resolving them into one. Let us next interrogate the patrons of the one. To them we say: Are being and one two different names for the same thing? But how can there be two names when there is nothing but one? Or you may identify them; but then the name will be either the name of nothing or of itself, i.e. of a name. Again, the notion of being is conceived of as a whole – in the words of Parmenides, 'like every way unto a rounded sphere.' And a whole has parts; but that which has parts is not one, for unity has no parts. Is being, then, one, because the parts of being are one, or shall we say that being is not a whole? In the former case, one is made up of parts; and in the latter there is still plurality, viz. being, and a whole which is apart from being. And being, if not all things, lacks something of the nature of being, and becomes not-being. Nor can being ever have come into existence, for nothing comes into existence except as a whole; nor can being have number, for that which has number is a whole or sum of number. These are a few of the difficulties which are accumulating one upon another in the consideration of being.

We may proceed now to the less exact sort of philosophers. Some of them drag down everything to earth, and carry on a war like that of the giants, grasping rocks and oaks in their hands. Their adversaries defend themselves warily from an invisible world, and reduce the substances of their opponents to the minutest fractions, until they are lost in generation and flux. The latter sort are civil people enough; but the materialists are rude and ignorant of dialectics; they must be taught how to argue before they can answer. Yet, for the sake of the argument, we may assume them to be better than they are, and able to give an account of themselves. They admit the existence of a mortal living creature, which is a body containing a soul, and to this they would not refuse to attribute qualities – wisdom, folly, justice and injustice. The soul, as they say, has a kind of body, but they do not like to assert of these qualities of the soul, either that they are corporeal, or that they have no existence; at this point they begin to make distinctions. 'Sons of earth,' we say to them, 'if both visible and invisible qualities exist, what is the common nature which is attributed to them by the term "being" or "existence"?' And, as they are incapable of answering this question, we may as well reply for them, that being is the power of doing or suffering. Then we turn to the friends of ideas: to them we say, 'You distinguish becoming from being?' 'Yes,' they will reply. 'And in becoming you participate through the bodily senses, and in being, by thought and the mind?' 'Yes.' And you mean by the word 'participation' a power of doing or suffering? To this they answer – I am acquainted with them, Theaetetus, and know their ways better than you do – that being can neither do nor suffer, though becoming may. And we rejoin: Does not the soul know? And is not 'being' known? And are not 'knowing' and 'being known' active and passive? That which is known is affected by knowledge, and therefore is in motion. And, indeed, how can we imagine that perfect being is a mere everlasting form, devoid of motion and soul? for there can be no thought without soul, nor can soul be devoid of motion. But neither can thought or mind be devoid of some principle of rest or stability. And as children say entreatingly, 'Give us both,' so the philosopher must include both the moveable and immoveable in his idea of being. And yet, alas! he and we are in the same difficulty with which we reproached the dualists; for motion and rest are contradictions – how then can they both exist? Does he who affirms this mean to say that motion is rest, or rest motion? 'No; he means to assert the existence of some third thing, different from them both, which neither rests nor moves.' But how can there be anything which neither rests nor moves? Here is a second difficulty about being, quite as great as that about not-being. And we may hope that any light which is thrown upon the one may extend to the other.
