The latter is our present concern, for the Sophist has no claims to
science or knowledge. Now the imitator, who has only opinion, may be
either the simple imitator, who thinks that he knows, or the dissembler,
who is conscious that he does not know, but disguises his ignorance. And
the last may be either a maker of long speeches, or of shorter speeches
which compel the person conversing to contradict himself. The maker of
longer speeches is the popular orator; the maker of the shorter is
the Sophist, whose art may be traced as being the

In commenting on the dialogue in which Plato most nearly approaches the great modern master of metaphysics there are several points which it will be useful to consider, such as the unity of opposites, the conception of the ideas as causes, and the relation of the Platonic and Hegelian dialectic.
The unity of opposites was the crux of ancient thinkers in the age of Plato: How could one thing be or become another? That substances have attributes was implied in common language; that heat and cold, day and night, pass into one another was a matter of experience 'on a level with the cobbler's understanding' (Theat.). But how could philosophy explain the connexion of ideas, how justify the passing of them into one another? The abstractions of one, other, being, not-being, rest, motion, individual, universal, which successive generations of philosophers had recently discovered, seemed to be beyond the reach of human thought, like stars shining in a distant heaven. They were the symbols of different schools of philosophy: but in what relation did they stand to one another and to the world of sense? It was hardly conceivable that one could be other, or the same different. Yet without some reconciliation of these elementary ideas thought was impossible. There was no distinction between truth and falsehood, between the Sophist and the philosopher. Everything could be predicated of everything, or nothing of anything. To these difficulties Plato finds what to us appears to be the answer of common sense—that Not-being is the relative or other of Being, the defining and distinguishing principle, and that some ideas combine with others, but not all with all. It is remarkable however that he offers this obvious reply only as the result of a long and tedious enquiry; by a great effort he is able to look down as 'from a height' on the 'friends of the ideas' as well as on the pre-Socratic philosophies. Yet he is merely asserting principles which no one who could be made to understand them would deny.
The Platonic unity of differences or opposites is the beginning of the modern view that all knowledge is of relations; it also anticipates the doctrine of Spinoza that all determination is negation. Plato takes or gives so much of either of these theories as was necessary or possible in the age in which he lived. In the Sophist, as in the Cratylus, he is opposed to the Heracleitean flux and equally to the Megarian and Cynic denial of predication, because he regards both of them as making knowledge impossible. He does not assert that everything is and is not, or that the same thing can be affected in the same and in opposite ways at the same time and in respect of the same part of itself. The law of contradiction is as clearly laid down by him in the Republic, as by Aristotle in his Organon. Yet he is aware that in the negative there is also a positive element, and that oppositions may be only differences. And in the Parmenides he deduces the many from the one and Not-being from Being, and yet shows that the many are included in the one, and that Not-being returns to Being.
In several of the later dialogues Plato is occupied with the connexion of the sciences, which in the Philebus he divides into two classes of pure and applied, adding to them there as elsewhere (Phaedr., Crat., Republic, States.) a superintending science of dialectic. This is the origin of Aristotle's Architectonic, which seems, however, to have passed into an imaginary science of essence, and no longer to retain any relation to other branches of knowledge. Of such a science, whether described as 'philosophia prima,' the science of ousia, logic or metaphysics, philosophers have often dreamed. But even now the time has not arrived when the anticipation of Plato can be realized. Though many a thinker has framed a 'hierarchy of the sciences,' no one has as yet found the higher science which arrays them in harmonious order, giving to the organic and inorganic, to the physical and moral, their respective limits, and showing how they all work together in the world and in man.
Plato arranges in order the stages of knowledge and of existence. They are the steps or grades by which he rises from sense and the shadows of sense to the idea of beauty and good. Mind is in motion as well as at rest (Soph.); and may be described as a dialectical progress which passes from one limit or determination of thought to another and back again to the first. This is the account of dialectic given by Plato in the Sixth Book of the Republic, which regarded under another aspect is the mysticism of the Symposium. He does not deny the existence of objects of sense, but according to him they only receive their true meaning when they are incorporated in a principle which is above them (Republic). In modern language they might be said to come first in the order of experience, last in the order of nature and reason. They are assumed, as he is fond of repeating, upon the condition that they shall give an account of themselves and that the truth of their existence shall be hereafter proved. For philosophy must begin somewhere and may begin anywhere,—with outward objects, with statements of opinion, with abstract principles. But objects of sense must lead us onward to the ideas or universals which are contained in them; the statements of opinion must be verified; the abstract principles must be filled up and connected with one another. In Plato we find, as we might expect, the germs of many thoughts which have been further developed by the genius of Spinoza and Hegel. But there is a difficulty in separating the germ from the flower, or in drawing the line which divides ancient from modern philosophy. Many coincidences which occur in them are unconscious, seeming to show a natural tendency in the human mind towards certain ideas and forms of thought. And there are many speculations of Plato which would have passed away unheeded, and their meaning, like that of some hieroglyphic, would have remained undeciphered, unless two thousand years and more afterwards an interpreter had arisen of a kindred spirit and of the same intellectual family. For example, in the Sophist Plato begins with the abstract and goes on to the concrete, not in the lower sense of returning to outward objects, but to the Hegelian concrete or unity of abstractions. In the intervening period hardly any importance would have been attached to the question which is so full of meaning to Plato and Hegel.
They differ however in their manner of regarding the question. For Plato is answering a difficulty; he is seeking to justify the use of common language and of ordinary thought into which philosophy had introduced a principle of doubt and dissolution. Whereas Hegel tries to go beyond common thought, and to combine abstractions in a higher unity: the ordinary mechanism of language and logic is carried by him into another region in which all oppositions are absorbed and all contradictions affirmed, only that they may be done away with. But Plato, unlike Hegel, nowhere bases his system on the unity of opposites, although in the Parmenides he shows an Hegelian subtlety in the analysis of one and Being.
It is difficult within the compass of a few pages to give even a faint outline of the Hegelian dialectic. No philosophy which is worth understanding can be understood in a moment; common sense will not teach us metaphysics any more than mathematics. If all sciences demand of us protracted study and attention, the highest of all can hardly be matter of immediate intuition. Neither can we appreciate a great system without yielding a half assent to it—like flies we are caught in the spider's web; and we can only judge of it truly when we place ourselves at a distance from it. Of all philosophies Hegelianism is the most obscure: and the difficulty inherent in the subject is increased by the use of a technical language. The saying of Socrates respecting the writings of Heracleitus—'Noble is that which I understand, and that which I do not understand may be as noble; but the strength of a Delian diver is needed to swim through it'—expresses the feeling with which the reader rises from the perusal of Hegel. We may truly apply to him the words in which Plato describes the Pre-Socratic philosophers: 'He went on his way rather regardless of whether we understood him or not'; or, as he is reported himself to have said of his own pupils: 'There is only one of you who understands me, and he does NOT understand me.'
Nevertheless the consideration of a few general aspects of the Hegelian philosophy may help to dispel some errors and to awaken an interest about it. (i) It is an ideal philosophy which, in popular phraseology, maintains not matter but mind to be the truth of things, and this not by a mere crude substitution of one word for another, but by showing either of them to be the complement of the other. Both are creations of thought, and the difference in kind which seems to divide them may also be regarded as a difference of degree. One is to the other as the real to the ideal, and both may be conceived together under the higher form of the notion. (ii) Under another aspect it views all the forms of sense and knowledge as stages of thought which have always existed implicitly and unconsciously, and to which the mind of the world, gradually disengaged from sense, has become awakened. The present has been the past. The succession in time of human ideas is also the eternal 'now'; it is historical and also a divine ideal. The history of philosophy stripped of personality and of the other accidents of time and place is gathered up into philosophy, and again philosophy clothed in circumstance expands into history. (iii) Whether regarded as present or past, under the form of time or of eternity, the spirit of dialectic is always moving onwards from one determination of thought to another, receiving each successive system of philosophy and subordinating it to that which follows—impelled by an irresistible necessity from one idea to another until the cycle of human thought and existence is complete. It follows from this that all previous philosophies which are worthy of the name are not mere opinions or speculations, but stages or moments of thought which have a necessary place in the world of mind. They are no longer the last word of philosophy, for another and another has succeeded them, but they still live and are mighty; in the language of the Greek poet, 'There is a great God in them, and he grows not old.' (iv) This vast ideal system is supposed to be based upon experience. At each step it professes to carry with it the 'witness of eyes and ears' and of common sense, as well as the internal evidence of its own consistency; it has a place for every science, and affirms that no philosophy of a narrower type is capable of comprehending all true facts.
