TWO:The principal object of Platos negative criticism had been to emphasise the distinction between reality and appearance in the world without, between sense, or imagination, and reason in the human soul. True to the mediatorial spirit of Greek thought, his object now was to bridge over the seemingly impassable gulf. We must not be understood to say that these two distinct, and to some extent contrasted, tendencies correspond to two definitely divided periods of his life. It is evident that the tasks of dissection and reconstruction were often carried on conjointly, and represented two aspects of an indivisible process. But on the whole there is good reason to believe that Plato, like other men, was more inclined to pull to pieces in his youth and to build up in his later days. We are, therefore, disposed to agree with those critics who assign both the Phaedrus and the Symposium to a comparatively advanced stage of Platonic speculation. It is less easy to decide which of the two was composed first, for there seems to be a greater maturity of thought in the one and of style in the other. For our purposes it will be most convenient to consider them together.The Academic theory of probability bears some resemblance to the Canonic of Epicurus, and may have been partially suggested by it. Both are distinguished from the Aristotelian and Stoic logic by the care with which they provide for the absence of contradictory evidence. In this point, however, the superiority of Carneades to Epicurus is very marked. It is not enough for him that a present impression should suggest a belief not inconsistent with past experience; in the true inductive spirit, he expressly searches for negative instances, and recommends the employment of experiment for this purpose. Still more philosophical is the careful and repeated analysis of attendant circumstances, a precaution not paralleled by anything in the slovenly method of his predecessor. Here the great value of scepticism as an element in mental training becomes at once apparent. The extreme fallibility of the intellectus sibi permissus had to be established before precautions could be adopted for its restraint. But the evidence accepted in proof of this fallibility has been very different at different times, and has itself given rise to more than one fallacious interpretation. With us it is, for the most part, furnished by experience. The circumstance that many demonstrable errors were formerly received as truths is quite sufficient to put us on our guard against untested opinions. With Bacon, it was not the erroneousness of previous systems, but their barrenness and immobility, which led him to question the soundness of their logic; and his doubts were confirmed by an analysis of the disturbing influences under which mens judgments are formed. The ancient Sceptics were governed entirely by priori considerations. Finding themselves confronted by an immense mass of contradictory opinions, they argued that some of these must be false as all could not possibly be true. And an analysis of the human faculties156 led them, equally on priori grounds, to the conclusion that these irreconcilable divergences were but the result and the reproduction of an interminable conflict carried on within the mind itself. They could not foresee how much time would do towards reducing the disagreement of educated opinion within a narrower compass. They did not know what the experience of experience itself would teach. And their criticisms on the logic and metaphysics of their opponents were rendered inconclusive, as against all certainty, by the extent to which they shared that logic and metaphysics themselves. Carneades, at least, seems to assume throughout that all existence is material, that there is a sharp distinction between subject and object in knowledge, and that there is an equally sharp distinction between sensation and reasoning in the processes by which knowledge is obtained. In like manner, his ethical scepticism all turns on the axiom, also shared by him with the Stoics, that for a man to be actuated by any motive but his own interest is mere folly.

- THREE:We have also to note that Plotinus arrives at his Absolute by a method apparently very different from that pursued by either of his teachers. Platos primal beauty is, on the face of it, an abstraction and generalisation from all the scattered and imperfect manifestations of beauty to be met with in our objective experience. And Aristotle is led to his conception of an eternal immaterial thought by two lines of analysis, both starting from the phenomena of external Nature. The problem of his Physics is to account for the perpetuity of motion. The problem of his Metaphysics is to explain the transformation of potential into actual existence. Plotinus, on the other hand, is always bidding us look within. What we admire in the objective world is but a reflex of ourselves. Mind is the sole reality; and to grasp this reality under its highest form, we must become like it. Thus the more we isolate our own personality and self-identity from the other interests and experiences of life, the more nearly do we approach to consciousness of and coalescence with the supreme identity wherein all things have their source.
- THREE:Zeno had more delicacy or less fortitude than Hipparchia; and the very meagre intellectual fare provided by Crates must have left his inquisitive mind unsatisfied. Accordingly we find him leaving this rather disappointing substitute for Socrates, to study philosophy under Stilpo the Megarian dialectician and Polemo the head of the Academy;14 while we know that he must have gone back to Heracleitus for the physical basis from which contemporary speculation had by this time cut itself completely free. At length, about the beginning of the third century B.C., Zeno, after having been a learner for twenty years, opened a school on his own account. As if to mark the practical bearing of his doctrine he chose one of the most frequented resorts in the city for its promulgation. There was at Athens a portico called the Poecile Stoa, adorned with frescoes by Polygn?tus, the greatest painter of the Cimonian period. It was among the monuments of that wonderful city, at once what the Loggia dei Lanzi is to Florence, and what Raphaels Stanze are to Rome; while, like the Place de la Concorde in Paris, it was darkened by the terrible associations of a revolutionary epoch. A century before Zenos time fourteen hundred Athenian citizens had been slaughtered under its colonnades by order of the Thirty. I will purify the Stoa, said the Cypriote stranger;15 and the feelings still associated with the word Stoicism prove how nobly his promise was fulfilled.
TWO:A new period begins with the Greek Humanists. We use this term in preference to that of Sophists, because, as has been shown, in specially dealing with the subject, half the teachers known under the latter denomination made it their business to popularise physical science and to apply it to morality, while the other half struck out an entirely different line, and founded their educational system on the express rejection of such investigations; their method being, in this respect, foreshadowed by the greatest poet of the age, who concentrates all his attention on the workings of the human mind, and followed by its greatest historian, with whom a similar study takes the place occupied by geography and natural history in the work of Herodotus. This absorption in human interests was unfavourable alike to the objects and to the methods of previous enquiry: to the former, as a diversion from the new studies; to the latter, as inconsistent with the flexibility and many-sidedness of conscious mind. Hence the true father of philosophical scepticism was Protagoras. With him, for the first time, we find full expression given to the proper sceptical attitude, which is one of suspense and indifference as opposed to absolute denial. He does not undertake to say whether the gods exist or not. He regards the real essence of Nature as unknowable, on account of the relativity which characterises all sensible impressions. And wherever opinions are divided, he undertakes to provide equally strong arguments for both sides of the question. He also anticipates the two principal tendencies exhibited by all future scepticism in its relation to practice. One is its devotion to humanity, under the double form of exclusive attention to human interests, and great mildness in the treatment of human beings. The other is a disposition to take custom and public opinion, rather than any physical or metaphysical law, for the standard and sanction of130 morality. Such scepticism might for the moment be hostile to religion; but a reconciliation was likely to be soon effected between them.
