TWO:From utter confusion to extreme nihilism there was but a single step. This step was taken by Gorgias, the Sicilian rhetorician, who held the same relation towards western Hellas and the Eleatic school as that which Protagoras held towards eastern Hellas and the philosophy of Heracleitus. He, like his eminent contemporary, was opposed to the thinkers whom, borrowing a useful term from the nomenclature of the last century, we may call the Greek physiocrats. To confute them, he wrote a book with the significant title, On Nature or Nothing: maintaining, first, that nothing exists; secondly, that if anything exists, we cannot know it; thirdly, that if we know it, there is no possibility of communicating our knowledge to others. The first thesis was established by pushing the Eleatic arguments against movement and change a little further; the second by showing that thought and existence are different, or else everything that is thought of would exist; the third by establishing a similar incommensurability between words and sensations. Grote96 has attempted to show that Gorgias was only arguing against the existence of a noumenon underlying phenomena, such as all idealists deny. Zeller has, however, convincingly proved that Gorgias, in common with every other thinker before Plato, was ignorant of this distinction;72 and we may add that it would leave the second and third theses absolutely unimpaired. We must take the whole together as constituting a declaration of war against science, an assertion, in still stronger language, of the agnosticism taught by Protagoras. The truth is, that a Greek controversialist generally overproved his case, and in order to overwhelm an adversary pulled down the whole house, even at the risk of being buried among the ruins himself. A modern reasoner, taking his cue from Gorgias, without pushing the matter to such an extreme, might carry on his attack on lines running parallel with those laid down by the Sicilian Sophist. He would begin by denying the existence of a state of Nature; for such a state must be either variable or constant. If it is constant, how could civilisation ever have arisen? If it is variable, what becomes of the fixed standard appealed to? Then, again, supposing such a state ever to have existed, how could authentic information about it have come down to us through the ages of corruption which are supposed to have intervened? And, lastly, granting that a state of Nature accessible to enquiry has ever existed, how can we reorganise society on the basis of such discordant data as are presented to us by the physiocrats, no two of whom agree with regard to the first principles of natural order; one saying that it is equality, another aristocracy, and a third despotism? We do not say that these arguments are conclusive, we only mean that in relation to modern thought they very fairly represent the dialectic artillery brought to bear by Greek humanism against its naturalistic opponents.But numerous as are the obligations, whether real or imaginary, of the Alexandrian to the Athenian teacher, they range over a comparatively limited field. What most interests a modern student in Platonismits critical preparation, its conversational dialectic, its personal episodes, its moral enthusiasm, its political superstructurehad apparently no interest for Plotinus as a writer. He goes straight to the metaphysical core of the system, and occupies himself with re-thinking it in its minutest details. Now this was just the part which had either not been286 discussed at all, or had been very insufficiently discussed by his predecessors. It would seem that the revival of Platonic studies had followed an order somewhat similar to the order in which Platos own ideas were evolved. The scepticism of the Apologia had been taken up and worked out to its last consequences by the New Academy. The theory of intuitive knowledge, the ethical antithesis between reason and passion, and the doctrine of immortality under its more popular form, had been resumed by the Greek and Roman Eclectics. Plutarch busied himself with the erotic philosophy of the Phaedrus and the Symposium, as also did his successor, Maximus Tyrius. In addition to this, he and the other Platonists of the second century paid great attention to the theology adumbrated in those dialogues, and in the earlier books of the Republic. But meanwhile Neo-Pythagoreanism had intervened to break the normal line of development, and, under its influence, Plutarch passed at once to the mathematical puzzles of the Timaeus. With Plato himself the next step had been to found a state for the application of his new principles; and such was the logic of his system, that the whole stress of adverse circumstances could not prevent the realisation of a similar scheme from being mooted in the third century; while, as we have seen, something more remotely analogous to it was at that very time being carried out by the Christian Church. Platos own disappointed hopes had found relief in the profoundest metaphysical speculations; and now the time has come when his labours in this direction were to engage the attention hitherto absorbed by the more popular or literary aspects of his teaching.


THREE:"The name of your witness?" she demanded, hoarsely."August 22nd, 1914.
FORE:This, then, was the revolution effected by Aristotle, that he found Greek thought in the form of a solid, and unrolled into a surface of the utmost possible tenuity, transparency, and extension. In so doing, he completed what Socrates and Plato had begun, he paralleled the course already described by Greek poetry, and he offered the first example of what since then has more than once recurred in the history of philosophy. It was thus that the residual substance of Locke and Berkeley was resolved into phenomenal succession by Hume. It was thus that the unexplained reality of Kant and Fichte was drawn out into a play of logical relations by Hegel. And, if we may venture on a forecast of the future towards which speculation is now advancing, it is thus that the limits imposed on human knowledge by positivists and agnostics in our own day, are yielding to the criticism of those who wish to establish either a perfect identity or a perfect equation between consciousness and being. This is the position represented in France by M. Taine, a thinker offering many points of resemblance to Aristotle, which it would be interesting to work out had we space at our command for the purpose. The forces which are now guiding English philosophy in an analogous direction have hitherto escaped observation on account of their disunion among themselves, and their intermixture with others of a different character. But on the whole we may say that the philosophy of Mill and his school corresponds very nearly in its practical idealism to Platos teaching; that Mr. Herbert Spencer approaches326 Aristotle on the side of theorising systematisation, while sharing to a more limited extent the metaphysical and political realism which accompanied it: that Lewes was carrying the same transformation a step further in his unfinished Problems of Life and Mind; that the philosophy of Mr. Shadworth Hodgson is marked by the same spirit of actuality, though not without a vista of multitudinous possibilities in the background; that the Neo-Hegelian school are trying to do over again for us what their master did in Germany; and that the lamented Professor Clifford had already given promise of one more great attempt to widen the area of our possible experience into co-extension with the whole domain of Nature.209He bought one eagerly enough, and stood spellbound on the pavement whilst he read. It was all here, even down to a signed copy of the confession. Lawrence had seen to that. Bruce turned into his club in a dazed kind of way. The smoking-room was full, he was the centre of a group, all of which seemed eager to shake hands. It was all so sudden that Bruce was not himself yet.
