“Whoever gives culture to one who does not possess knowledge, desires that he should no longer remain what he is. He desires to direct him to reason, and this is to make him not the same as he is.” And Euthydemus, when the others say that he lies, answers, “Who lies, says what is not; men cannot say what is not, and thus no one can lie.”[94] And again Dionysodorus says, “You have a dog, this dog has young, and is a father; thus a dog is your father, and you are brother to its young.”[95] Sequences put together thus are constantly found in critical treatises.
With this comes the question which the nature of thought brings along with it. If the field of argument, that which consciousness holds to be firmly established, is shaken by reflection, what is man now to take as his ultimate basis? For something fixed there must be. This is either the good, the universal, or the individuality, the arbitrary will of the subject; and both may be united, as is shown later on in Socrates. To the Sophists the satisfaction of the individual himself was now made ultimate, and since they made everything uncertain, the fixed point was in the assertion, “it is my desire, my pride, glory, and honour, particular subjectivity, which I make my end.” Thus the Sophists are reproached for countenancing personal affections, private interests, &c. This proceeds directly from the nature of their culture, which, because it places ready various points of view, makes it depend on the pleasure of the subject alone which shall prevail, that is, if fixed principles do not determine. Here the danger lies. This takes place also in the present day where the right and the true in our actions is made to depend on good intention and on my own conviction. The real end of the State, the best administration and constitution, is likewise to demagogues very vague.
On account of their formal culture, the Sophists have a place in Philosophy; on account of their reflection they have not. They are associated with Philosophy in that they do not remain at concrete reasoning, but go on, at least in part, to ultimate determinations. A chief part of their culture was the generalization of the Eleatic mode of thought and its extension to the whole content of knowledge and of action; the positive thus comes in as, and has become, utility. To go into particulars respecting the Sophists would lead us too far; individual Sophists have their place in the general history of culture. The celebrated Sophists are very numerous; the most celebrated amongst them are Protagoras, Gorgias, and also Prodicus, the teacher of Socrates, to whom Socrates ascribes the well-known myth of “The choice of Hercules”[96]—an allegory, beautiful in its own way, which has been repeated hundreds and thousands of times. I will deal only with Protagoras and Gorgias, not from the point of view of culture, but in respect of proving further how the general knowledge which they extended to everything, has, with one of them, the universal form which makes it pure science. Plato is the chief source of our acquaintanceship with the Sophists, for he occupied himself largely with them; then we have Aristotle’s own little treatise on Gorgias; and Sextus Empiricus, who preserved for us much of the philosophy of Protagoras.
1. PROTAGORAS.
Protagoras, born at Abdera,[97] was somewhat older than Socrates; little more is known of him, nor, indeed, could there be much known. For he led a uniform life, since he spent it in the study of the sciences; he appeared in Greece proper as the first public teacher. He read his writings[98] like the rhapsodists and poets, the former of whom sang the verses of others, and the latter their own. There were then no places of learning, no books from which men could be taught, for to the ancients, as Plato says,[99] “the chief part of culture” (_ραιδείας_) “consisted in being skilled” (_δεινόν_) “in poetry,” just as with us fifty years ago the principal instruction of the people consisted of Bible History and Biblical precepts. The Sophists now gave, in place of a knowledge of the poets, an acquaintanceship with thought. Protagoras also came to Athens and there lived for long, principally with the great Pericles, who also entered into this culture. Indeed, the two once argued for a whole day as to whether the dart or the thrower or he who arranged the contest was guilty of the death of a man who thus met his death.[100] The dispute is over the great and important question of the possibility of imputation; guilt is a general expression, the analysis of which may undoubtedly become a difficult and extensive undertaking. In his intercourse with such men, Pericles developed his genius for eloquence; for whatever kind of mental occupation may be in question, a cultivated mind can alone excel in it; and true culture is only possible through pure science. Pericles was a powerful orator, and we see from Thucydides how deep a knowledge he had of the State and of his people. Protagoras had the same fate as Anaxagoras, in being afterwards banished from Athens. The cause of this sentence was a work written by him beginning, “As to the gods, I am not able to say whether they are or are not; for there is much which prevents this knowledge, both in the obscurity of the matter, and in the life of man which is so short.” This book was also publicly burned in Athens by command of the State, and, so far as we know, it was the first to be treated so. At the age of seventy or ninety years Protagoras was drowned while on a voyage to Sicily.[101] Protagoras was not, like other Sophists, merely a teacher of culture, but likewise a deep and solid thinker, a philosopher who reflected on fundamental determinations of an altogether universal kind. The main point in his system of knowledge he expressed thus: “Man is the measure of all things; of that which is, that it is; of that which is not, that it is not.”[102] On the one hand, therefore, what had to be done was to grasp thought as determined and as having content; but, on the other, to find the determining and content-giving; this universal determination then becomes the standard by which everything is judged. Now Protagoras’ assertion is in its real meaning a great truth, but at the same time it has a certain ambiguity, in that as man is the undetermined and many-sided, either he may in his individual particularity, as this contingent man, be the measure, or else self-conscious reason in man, man in his rational nature and his universal substantiality, is the absolute measure. If the statement is taken in the former sense, all is self-seeking, all self-interest, the subject with his interests forms the central point; and if man has a rational side, reason is still something subjective, it is “he.” But this is just the wrong and perverted way of looking at things which necessarily forms the main reproach made against the Sophists—that they put forward man in his contingent aims as determining; thus with them the interest of the subject in its particularity, and the interest of the same in its substantial reason are not distinguished.
The same statement is brought forward in Socrates and Plato, but with the further modification that here man, in that he is thinking and gives himself a universal content, is the measure. Thus here the great proposition is enunciated on which, from this time forward, everything turns, since the further progress of Philosophy only explains it further: it signifies that reason is the end of all things. This proposition further expresses a very remarkable change of position in asserting that all content, everything objective, is only in relation to consciousness; thought is thus in all truth expressed as the essential moment, and thereby the Absolute takes the form of the thinking subjectivity which comes before us principally in Socrates. Since man, as subject, is the measure of everything, the existent is not alone, but is for my knowledge. Consciousness is really the producer of the content in what is objective, and subjective thinking is thus really active. And this view extends even to the most modern philosophy, as when, for instance, Kant says that we only know phenomena, _i.e._ that what seems to us to be objective reality, is only to be considered in its relation to consciousness, and does not exist without this relation. The fact that the subject as active and determining brings forth the content, is the important matter, but now the question comes as to how the content is further determined—whether it is limited to the particularity of consciousness or is determined as the universal, the existent in and for itself. God, the Platonic Good, is certainly at first a product of thought, but in the second place He is just as really in and for Himself. Since I, as existent, fixed and eternal, only recognize what is in its content universal, this, posited as it is by me, is likewise the implicitly objective, not posited by me.
Protagoras himself shows us much more of what is implied in his theory, for he says, “Truth is a manifestation for consciousness. Nothing is in and for itself one, but everything has a relative truth only,” _i.e._ it is what it is but for another, which is man. This relativity is by Protagoras expressed in a way which seems to us in some measure trivial, and belongs to the first beginnings of reflective thought. The insignificant examples which he adduces (like Plato and Socrates when they follow out in them the point of view of reflection), by way of explanation, show that in Protagoras’ understanding what is determined is not grasped as the universal and identical with self. Hence the exemplifications are taken mostly from sensuous manifestation. “In a wind it may be that one person is cold and another is not; hence of this wind we cannot tell whether in itself it is cold or hot.”[103] Frost and heat are thus not anything which exist, but only are in their relation to a subject; were the wind cold in itself, it would always be so to the subject. Or again, “if we have here six dice, and place by them four others, we should say of the former that there are more of them. But, again, if we put twelve by them we say that these first six are the fewer.”[104] Because we say of the same number that it is more and fewer, the more and the less is merely a relative determination; thus what is the object, is so in the idea present to consciousness only. Plato, on the contrary, considered one and many, not like the Sophists in their distinction, but as being one and the same.
Plato says further on this point, that the white, warm, &c., or everything that we say of things, does not exist for itself, but that the eye, sensation, is necessary to make it for us. This reciprocal movement is what first creates the white, and in it the white is not a thing in itself, but what we have present is a seeing eye, or, to speak generally, sight, and particularly the seeing of white, the feeling of warmth, &c. Undoubtedly warmth, colour, &c., really are only in relation to another, but the conceiving mind divides itself into itself and into a world in which each also has its relation. This objective relativity is expressed better in the following way. If the white were in itself, it would be that which brought forth the sensation of it; it would be the action or the cause, and we, on the contrary, the passive and receptive. But the object which thus requires to be active, is not active until it enters into (_ξυνέλθῃ_) relation with the passive; similarly the passive is only in relation to the active. Thus what is said in defining anything never concerns the thing as in itself, but clearly only as being related to something else. Nothing is thus constituted in and for itself as it appears, but the truth is just this phenomenon to which our activity contributes. As things appear to the healthy man they are thus not in themselves, but for him; as they appear to the sick or deranged man, they are to him, without our being able to say that as they appear to him, they are not true.[105] We feel the awkwardness of calling any such thing true, for after all the existent, if related to consciousness, is yet not related to it as fixed, but to sensuous knowledge; and then this consciousness itself is a condition, _i.e._ something which passes away. Protagoras rightly recognized this double relativity when he says, “Matter is a pure flux, it is not anything fixed and determined in itself, for it can be everything, and it is different to different ages and to the various conditions of waking and sleep, &c.”[106] Kant separates himself from this standpoint only in that he places the relativity in the “I,” and not in objective existence. The phenomenon is, according to him, nothing but the fact of there being outside an impulse, an unknown _x_, which first receives these determinations through our feeling.
Even if there were an objective ground for our calling one thing cold and another warm, we could indeed say that they must have diversity in themselves, but warmth and cold first become what they are in our feeling. Similarly it can only be in our conception that things are outside of us, etc. But if the experience is quite correctly called a “phenomenon,” _i.e._ something relative, because it does not come to pass without the determinations of the activity of our senses, nor without categories of thought, yet that one, all-pervading, universal, which permeates all experience, which to Heraclitus was necessity, has to be brought into consciousness.
We see that Protagoras possesses great powers of reflective thought, and indeed reflection on consciousness came to consciousness with Protagoras. But this is the form of manifestation which was again taken by the later sceptics. The phenomenal is not sensuous Being, for because I posit this as phenomenal, I assert its nullity. But the statements “What is, is only for consciousness,” or “The truth of all things is the manifestation of them in and for consciousness,” seem quite to contradict themselves. For it appears as though a contradiction were asserted—first that nothing is in itself as it appears, and then that it is true as it appears. But objective significance must not be given to the positive, to what is true, as if, for example, this were white in itself because it appears so; for it is only this manifestation of the white that is true, the manifestation being just this movement of the self-abrogating sensuous Being, which, taken in the universal, stands above consciousness as truly as above Being. The world is consequently not only phenomenal in that it is for consciousness, and thus that its Being is only one relative to consciousness, for it is likewise in itself phenomenal. The element of consciousness which Protagoras has demonstrated, and owing to which the developed universal has in it the moment of the negative Being-for-another, has thus indeed to be asserted as a necessary moment; but taken for itself, alone and isolated, it is one-sided, since the moment of implicit Being is likewise essential.
2. GORGIAS.
This scepticism reached a much deeper point in Gorgias of Leontium in Sicily, a man of great culture, and also distinguished as a statesman. During the Peloponnesian war he was, in Ol. 88, 2 (427 B.C.), a few years after Pericles’ death in Ol. 87, 4, sent from his native town to Athens.[107] And when he attained his object, he went through many other Greek towns, such as Larissa in Thessaly, and taught in them. Thus he obtained great wealth, along with much admiration, and this lasted till his death at over a hundred years of age.
He is said to have been a disciple of Empedocles, but he also knew the Eleatics, and his dialectic partakes of the manner and method of the latter; indeed Aristotle, who preserves this dialectic, in the work _De Xenophane, Zenone et Gorgia_, which has indeed only come to us in fragments, deals with them together. Sextus Empiricus also gives us in full the dialectic of Gorgias. He was strong in the dialectic requisite for eloquence, but his preeminence lies in his pure dialectic respecting the quite universal categories of Being and non-being, which indeed is not like that of the Sophists. Tiedemann (Geist. der Spec. Phil. vol. I. p. 362) says very falsely: “Gorgias went much further than any man of healthy mind could go.” Tiedemann could say of every philosopher that he went further than healthy human understanding, for what men call healthy understanding is not Philosophy, and is often far from healthy. Healthy human understanding possesses the modes of thought, maxims, and judgments of its time, the thought-determinations of which dominate it without its being conscious thereof. In this way Gorgias undoubtedly went further than healthy understanding.
Before Copernicus it would have been contrary to all healthy human understanding if anyone had said that the earth went round the sun, or before the discovery of America, if it were said that there was a continent there. In India or in China a republic would even now be contrary to all healthy understanding. The dialectic of Gorgias moves more purely in Notion than that found in Protagoras. Since Protagoras asserted the relativity, or the non-implicit nature of all that is, this only exists in relation to another which really is essential to it; and this last, indeed, is consciousness. Gorgias’ demonstration of the non-implicitness of Being is purer, because he takes in itself what passes for real existence without presupposing that other, and thus shows its own essential nullity and separates therefrom the subjective side and Being as it is for the latter.
Gorgias’ treatise “On Nature,” in which he composes his dialectic, falls, according to Sextus Empiricus (adv. Math. VII. 65), into three parts. “In the first he proves that” (objectively) “nothing exists, in the second” (subjectively), “that assuming that Being is, it cannot be known; and in the third place” (both subjectively and objectively), “that were it to exist and be knowable, no communication of what is known would be possible.” Gorgias was a congenial subject to Sextus, but the former still proved, and this is what the Sceptics ceased to do. Here very abstract thought-determinations regarding the most speculative moments of Being and non-being, of knowledge, and of bringing into existence, of communicating knowledge, are involved; and this is no idle talk, as was formerly supposed, for Gorgias’ dialectic is of a quite objective kind, and is most interesting in content.
_a._ “If anything is,” (this “anything” is, however, a makeshift that we are in the habit of using in our conversation, and which is, properly speaking, inappropriate, for it implies an opposition of subject and predicate, while at present the “is” alone is in question)—then “if it _is_” (and now it becomes for the first time defined as subject) “it is either the existent or the non-existent, or else existence and non-existence. It is now evident of these three that they are not.”[108] _α_. “That which is not, is not; for if Being belonged to it, there would at the same time be existence and non-existence. That is, in so far as it is thought of as non-existent, it is not; but in so far as it _is_ the non-existent, it must exist. But it cannot at the same time be and not be. Again, if the non-existent is, the existent is not, for the two are opposed. Thus, if Being pertained to non-being, non-being would belong to Being. But if Being does not exist, no more does non-being.”[109] This is with Gorgias a characteristic mode of reasoning.[110] _β_. “But in proving,” Aristotle adds to the passages just quoted, “that the existent is not, he follows Melissus and Zeno.” This is the dialectic already brought forward by them. “If Being is, it is contradictory to predicate a quality to it, and if we do this, we express something merely negative about it.”
_αα_. For Gorgias says: “What is, either is in itself (_ἀΐδιον_) being without beginning, or it has originated,” and he now shows that it could neither be the one nor the other, for each leads to contradiction. “It cannot be the former, for what is in itself has no beginning, and is the infinite,” and hence likewise undetermined and indeterminable. “The infinite is nowhere, for if it is anywhere, that in which it is, is different from it.” Where it is, it is in another, “but that is not infinite which is different from another, and contained in another. Just as little is it contained in itself, for then that in which it is, and that which is therein, would be the same. What it is in, is the place; that which is in this, is the body; but that both should be the same is absurd. The infinite does not thus exist.”[111] This dialectic of Gorgias regarding the infinite is on the one hand limited, because immediate existence has certainly no beginning and no limit, but asserts a progression into infinitude; the self-existent Thought, the universal Notion, as absolute negativity, has, however, limits in itself. On the other hand, Gorgias is quite right, for the bad, sensuous infinite is nowhere present, and thus does not exist, but is a Beyond of Being; only we may take what Gorgias takes as a diversity of place, as being diversity generally.
Thus, instead of placing the infinite, like Gorgias, sometimes in another, sometimes within itself, _i.e._ sometimes maintaining it to be different, sometimes abrogating the diversity, we may say better and more universally, that this sensuous infinite is a diversity which is always posited as different from the existent, for it is just the being different from itself.
“In the same way Being has not originated, because it must then have come either from the existent or from the non-existent. From the existent it did not arise, for then it would be already; just as little from the non-existent, because this cannot beget anything.”[112] The sceptics followed this up further. The object to be contemplated hence ever becomes posited under determinations with ‘either’ ‘or,’ which then contradict one another. But that is not the true dialectic, because the object resolves itself into those determinations only; when nothing follows respecting the nature of the object itself, then, as is already proved, the object must be necessarily in one determination, and not in and for itself.
_ββ_. In a similar way Gorgias shows “of what exists, that it must either be one or many; but neither is possible. For as one, it would have a certain magnitude, or continuity, or number, or body, but all this is not one, but different, divisible. Every sensuous one is, in fact, necessarily another, a manifold. If it is not one, it cannot be many, for the many is many ones.”[113] _γ_. “Similarly both, Being and non-being, cannot exist at the same time. If one exists as much as the other, they are the same, and therefore neither of them is, for the non-being does not exist, and hence neither does the Being, since it is identical with it. Nor can they, on the other hand, both exist, for if they are identical, I cannot express them both,”[114] and thus both do not exist, for if I express both, I differentiate. This dialectic, which Aristotle (De Xenoph. &c., c. 5) likewise designates as peculiar to Gorgias, has its truth. In speaking of Being and non-being, we always say the opposite to what we wish. Being and non-being are the same, just as they are not the same; if they are the same, I speak of the two as different: if different, I express the same predicate of them, diversity. This dialectic is not to be despised by us, as if it dealt with empty abstractions, for these categories are, on the one hand, in their purity the most universal, and if, on the other hand, they are not the ultimate, yet it is always Being or non-being that are in question; they are not, however, definitely fixed and divided off, but are self-abrogating. Gorgias is conscious that they are vanishing moments, while the ordinary unconscious conception also has present to it this truth, but knows nothing about it.
_b._ The relation of the conceiver to conception, the difference between conception and Being, is a subject which is in our mouths to-day. “But if there is an ‘is,’ it is unknowable and unthinkable, for what is presented is not the existent” but only a presentation. “If what is presented is white, it is the case that white is presented; if what is presented is not the really existent, it is the case that what is, is not presented. For if what is presented is the real existent, everything that is presented also exists, but no one says that if a flying man, or waggon riding on the sea were presented to us, it would exist. Further, if what is presented is the existent, the non-existent is not presented, for opposites are in opposition. But this non-existent is everywhere presented as it is in Scylla and the Chimæra.[115] Gorgias on the one hand pronounces a just polemic against absolute realism, which, because it represents, thinks to possess the very thing itself, when it only has a relative, but he falls, on the other hand, into the false idealism of modern times, according to which thought is always subjective only, and thus not the existent, since through thought an existent is transformed into what is thought.”
_c._ We finally have the basis of the dialectic of Gorgias in respect of the third point, that knowledge cannot be imparted, in this: “If the existent were presented, it could still not be expressed and imparted. Things are visible, audible, &c., or are experienced. The visible is grasped through sight, the audible through hearing, and not the contrary way; thus, the one cannot be indicated by the other. Speech, by which the existent has to be expressed, is not the existent; what is imparted is thus not the existent, but only words.[116] In this manner Gorgias’ dialectic is the laying hold of this difference exactly as again occurred in Kant; if I maintain this difference, certainly that which is, cannot be known.”
This dialectic is undoubtedly impregnable to those who maintain sensuous Being to be real. But its truth is only this movement to posit itself negatively as existent, and the unity is the reflection that the existent, comprehended also as non-existent, becomes, in this comprehension of it, universal. That this existent cannot be imparted, must likewise be held most strongly, for _this_ individual cannot be expressed. Philosophic truth is thus not only expressed as if there were another truth in sensuous consciousness; but Being is present in that philosophic truth expresses it. The Sophists thus also made dialectic, universal Philosophy, their object, and they were profound thinkers.
B.—SOCRATES.
Consciousness had reached this point in Greece, when in Athens the great form of Socrates, in whom the subjectivity of thought was brought to consciousness in a more definite and more thorough manner, now appeared. But Socrates did not grow like a mushroom out of the earth, for he stands in continuity with his time, and thus is not only a most important figure in the history of Philosophy—perhaps the most interesting in the philosophy of antiquity—but is also a world-famed personage. For a mental turning-point exhibited itself in him in the form of philosophic thought. If we shortly recall the periods already passed over, we find that the ancient Ionic philosophers certainly thought, but without reflecting on the thought or defining its product as thought. The Atomists made objective existence into thoughts, but these were to them only abstractions, pure entities. Anaxagoras, on the other hand, raised thought as such, into a principle which thereby presented itself as the all-powerful Notion, as the negative power over all that is definite and existent. Protagoras finally expresses thought as real existence, but it is in this its movement, which is the all-resolving consciousness, the unrest of the Notion. This unrest is in itself at the same time something restful or secure. But the fixed point of motion as such, is the ‘I,’ for it has the moments of movement outside of it; as the self-retaining, which only abrogates what is different, the ‘I’ is negative unity, but just in that very way individual, and not yet the universal reflected within itself. Now we here find the ambiguity of dialectic and sophistry, which rests in the fact that if the objective disappears, the signification of the fixed subjective is either that of the individual opposed to the objective, and thereby the contingent and lawless will, or that of the objective and universal in itself. Socrates expresses real existence as the universal ‘I,’ as the consciousness which rests in itself; but that is the good as such, which is free from existent reality, free from individual sensuous consciousness of feeling and desire, free finally from the theoretically speculative thought about nature, which, if indeed thought, has still the form of Being and in which I am not certain of my existence.
