THREE:Plato had begun by condemning poetry only in so far as it was inconsistent with true religion and morality. At last, with his usual propensity to generalise, he condemned it and, by implication, every imitative art qua art, as a delusion and a sham, twice removed from the truth of things, because a copy of the phenomena which are themselves unreal representations of an archetypal idea. His iconoclasm may remind us of other ethical theologians both before and after, whether Hebrew, Moslem, or Puritan. If he does not share their fanatical hatred for plastic and pictorial representations, it is only because works of that class, besides being of a chaster character, exercised far less power over the Greek imagination than epic and dramatic poetry. Moreover, the tales of the poets were, according to Plato, the worst lies of any, since they were believed to be true; whereas statues and pictures differed too obviously from their originals for any such illusion to be produced in their case. Like the Puritans, again, Plato sanctioned the use of religious hymns, with the accompaniment of music in its simplest and most elevated forms. Like them, also, he would have approved of literary fiction when it was employed for edifying purposes. Works like the Faery Queen, Paradise Lost, and the Pilgrims Progress, would have been his favourites in English literature; and he might have242 extended the same indulgence to fictions of the Edgeworthian type, where the virtuous characters always come off best in the end.After resolving virtue into knowledge of pleasure, the next questions which would present themselves to so keen a thinker were obviously, What is knowledge? and What is pleasure? The Theaettus is chiefly occupied with a discussion of the various answers already given to the first of these enquiries. It seems, therefore, to come naturally next after the Protagoras; and our conjecture receives a further confirmation when we find that here also a large place is given to the opinions of the Sophist after whom that dialogue is named; the chief difference being that the points selected for controversy are of a speculative rather than of a practical character. There is, however, a close connexion between the argument by which Protagoras had endeavoured to prove that all mankind are teachers of virtue, and his more general principle that man is the measure of all things. And perhaps it was the more obvious difficulties attending the latter view which led Plato, after some hesitation, to reject the former along206 with it. In an earlier chapter we gave some reasons for believing that Protagoras did not erect every individual into an arbiter of truth in the sweeping sense afterwards put upon his words. He was probably opposing a human to a theological or a naturalistic standard. Nevertheless, it does not follow that Plato was fighting with a shadow when he pressed the Protagorean dictum to its most literal interpretation. There are plenty of people still who would maintain it to that extent. Wherever and whenever the authority of ancient traditions is broken down, the doctrine that one mans opinion is as good as anothers immediately takes its place; or rather the doctrine in question is a survival of traditionalism in an extremely pulverised form. And when we are told that the majority must be rightwhich is a very different principle from holding that the majority should be obeyedwe may take it as a sign that the loose particles are beginning to coalesce again. The substitution of an individual for a universal standard of truth is, according to Plato, a direct consequence of the theory which identifies knowledge with sense-perception. It is, at any rate, certain that the most vehement assertors of the former doctrine are also those who are fondest of appealing to what they and their friends have seen, heard, or felt; and the more educated among them place enormous confidence in statistics. They are also fond of repeating the adage that an ounce of fact is worth a ton of theory, without considering that theory alone can furnish the balance in which facts are weighed. Plato does not go very deep into the rationale of observation, nor in the infancy of exact science was it to be expected that he should. He fully recognised the presence of two factors, an objective and a subjective, in every sensation, but lost his hold on the true method in attempting to trace a like dualism through the whole of consciousness. Where we should distinguish between the mental energies and the physical processes underlying them, or between the207 elements respectively contributed to every cognition by immediate experience and reflection, he conceived the inner and outer worlds as two analogous series related to one another as an image to its original.
He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections
