THREE:The old religions of Greece and Italy were essentially oracular. While inculcating the existence of supernatural beings, and prescribing the modes according to which such beings were to be worshipped, they paid most attention to the interpretation of the signs by which either future events in general, or the consequences of particular actions, were supposed to be divinely revealed. Of these intimations, some were given to the whole world, so that he who ran might read, others were reserved for certain favoured localities, and only communicated through the appointed ministers of the god. The Delphic oracle in particular enjoyed an enormous reputation both among Greeks and barbarians for guidance afforded under the latter conditions; and during a considerable period it may even be said to have directed the course of Hellenic civilisation. It was also under this form that supernatural religion suffered most injury from the great intellectual movement which followed the Persian wars. Men who had learned to study the constant sequences of Nature for themselves, and to shape their conduct according to fixed principles of prudence or of justice, either thought it irreverent to trouble the god about questions on which they were competent to form an opinion for themselves, or did not choose to place a well-considered scheme at the mercy of his possibly interested responses. That such a revolution occurred about the middle of the fifth century B.C., seems proved by the great change of tone in reference to this subject which one perceives on passing from Aeschylus to Sophocles. That anyone should question the veracity of an oracle is a supposition which never crosses the mind of the elder dramatist. A knowledge of augury counts among the greatest benefits222 conferred by Prometheus on mankind, and the Titan brings Zeus himself to terms by his acquaintance with the secrets of destiny. Sophocles, on the other hand, evidently has to deal with a sceptical generation, despising prophecies and needing to be warned of the fearful consequences brought about by neglecting their injunctions.When we last had occasion to speak of the Platonic school, it was represented by Polemo, one of the teachers from whose lessons Zeno the Stoic seems to have compiled his system. Under his superintendence, Platonism had completely abandoned the metaphysical traditions of its founder. Physics and dialectics had already been absorbed by Aristotelianism. Mathematics had passed into the hands of experts. Nothing remained but the theory of ethics; and, as an ethical teacher, Polemo was only distinguished from the Cynics by the elegance and moderation of his tone. Even this narrow standing-ground became untenable when exposed to the formidable competition of Stoicism. The precept, Follow Nature, borrowed by the new philosophy from Polemo, acquired a far deeper significance than he could give it, when viewed in the light of an elaborate physical system showing what Nature was, and whither her guidance led. But stone after stone had been removed from the Platonic superstructure and built into the walls of other edifices, only to bring its145 original foundation the more prominently into sight. This was the initial doubt of Socrates, widened into the confession of universal ignorance attributed to him by Plato in the Apologia. Only by returning to the exclusively critical attitude with which its founder had begun could the Academy hope to exercise any influence on the subsequent course of Greek speculation. And it was also necessary that the agnostic standpoint should be taken much more in earnest by its new representatives than by Socrates or Plato. With them it had been merely the preparation for a dogmatism even more self-confident than that of the masters against whom they fought; but if in their time such a change of front might seem compatible with the retention of their old strongholds, matters now stood on a widely different footing. Experience had shown that the purely critical position could not be abandoned without falling back on some one or other of the old philosophies, or advancing pretensions inconsistent with the dialectic which had been illustrated by their overthrow. The course marked out for Platos successors by the necessities of thought might have been less evident had not Pyrrhonism suddenly revealed to them where their opportunities lay, and at the same time, by its extinction as an independent school, allowed them to step into the vacant place.

FORE:Her despair is but the inverted image of Platos hope, the return to a purer state of being where knowledge will no longer be obscured by passing through the perturbing medium of sight and touch. Again, modern apologists for the injustice and misery of the present system144 argue that its inequalities will be redressed in a future state. Plato conversely regarded the sufferings of good men as a retribution for former sin, or as the result of a forgotten choice. The authority of Pindar and of ancient tradition generally may have influenced his belief, but it had a deeper ground in the logic of a spiritualistic philosophy. The dualism of soul and body is only one form of his fundamental antithesis between the changeless essence and the transitory manifestations of existence. A pantheism like Spinozas was the natural outcome of such a system; but his practical genius or his ardent imagination kept Plato from carrying it so far. Nor in the interests of progress was the result to be regretted; for theology had to pass through one more phase before the term of its beneficent activity could be reached. Ethical conceptions gained a new241 significance in the blended light of mythology and metaphysics; those who made it their trade to pervert justice at its fountain-head might still tremble before the terrors of a supernatural tribunal; or if Plato could not regenerate the life of his own people he could foretell what was to be the common faith of Europe in another thousand years; and memory, if not hope, is the richer for those magnificent visions where he has projected the eternal conflict between good and evil into the silence and darkness by which our lives are shut in on every side.

FORE:A difficulty which arises in hardening tools is because of the contraction of the steel which takes place in proportion to the change of temperature; and as the time of cooling is in proportion to the thickness or size of a piece, it follows, of course, that there is a great strain and a tendency to break the thinner parts before the thicker parts have time to cool; this strain may take place either from cooling one side first, or more rapidly than another.
