TWO:No sooner did the two imperial systems lose their ascendency than the germs which they had temporarily overshadowed sprang up into vigorous vitality, and for more than4 five centuries dominated the whole course not only of Greek but of European thought. Of these by far the most important was the naturalistic idea, the belief that physical science might be substituted for religious superstitions and local conventions as an impregnable basis of conduct. In a former chapter1 we endeavoured to show that, while there are traces of this idea in the philosophy of Heracleitus, and while its roots stretch far back into the literature and popular faith of Greece, it was formulated for the first time by the two great Sophists, Prodicus and Hippias, who, in the momentous division between Nature and Law, placed themselvesHippias more particularlyon the side of Nature. Two causes led to the temporary discredit of their teaching. One was the perversion by which natural right became the watchword of those who, like Platos Callicles, held that nothing should stand between the strong man and the gratification of his desire for pleasure or for power. The other was the keen criticism of the Humanists, the friends of social convention, who held with Protagoras that Nature was unknowable, or with Gorgias that she did not exist, or with Socrates that her laws were the secret of the gods. It was in particular the overwhelming personal influence of Socrates which triumphed. He drew away from the Sophists their strongest disciple, Antisthenes, and convinced him that philosophy was valuable only in so far as it became a life-renovating power, and that, viewed in this light, it had no relation to anything outside ourselves. But just as Socrates had discarded the physical speculations of former teachers, so also did Antisthenes discard the dialectic which Socrates had substituted for them, even to the extent of denying that definition was possible.2 Yet he seems to have kept a firm hold on the two great ideas that were the net result of all previous philosophy, the idea of a cosmos, the common citizenship of which made all men5 potentially equal,3 and the idea of reason as the essential prerogative of man.4Empire, when it came to Athens, came almost unsought. The Persian invasions had made her a great naval power; the free choice of her allies placed her at the head of a great maritime confederacy. The sudden command of vast resources and the tension accumulated during ages of repose, stimulated all her faculties into preternatural activity. Her spirit was steeled almost to the Dorian temper, and entered into victorious rivalry with the Dorian Muse. Not only did her fleet sweep the sea, but her army, for once, defeated Theban hoplites in the field. The grand choral harmonies of Sicilian song, the Sicyonian recitals of epic adventure, were rolled back into a framework for the spectacle of individual souls meeting one another in argument, expostulation, entreaty, and defiance; a nobler Doric edifice rose to confront the Aeginetan temple of Athn; the strained energy of Aeginetan combatants was relaxed into attitudes of reposing power, and the eternal smile on their faces was deepened into the sadness of unfathomable thought. But to the violet-crowned city, Athn was a giver of wealth and wisdom rather than of prowess; her empire rested on the contributions of unwilling allies, and on a technical proficiency which others were sure to equal in time; so that the Corinthian orators could say with justice that Athenian skill was more easily acquired than Dorian valour. At once receptive and communicative, Athens absorbed all that Greece could teach her, and then returned it in a more elaborate form, but without the freshness of its earliest inspiration. Yet there was one field that still afforded scope for creative originality. Habits of analysis, though fatal to spontaneous production, were favourable, or rather were necessary, to the growth of a new philosophy. After the exhaustion of every limited idealism, there remained that highest idealisation which is the reduction of all past experience to a method available for the guidance129 of all future action. To accomplish this last enterprise it was necessary that a single individual should gather up in himself the spirit diffused through a whole people, bestowing on it by that very concentration the capability of an infinitely wider extension when its provisional representative should have passed away from the scene.
TWO:Such a system was likely to result, and before long actually did result, in the realisation of the Logos on earth, in the creation of an inspired and infallible Church, mediating between God and man; while it gave increased authority and expansive power to another superstition which already existed in Philos time, and of which his Logos doctrine was perhaps only the metaphysical sublimation,the superstition that the divine Word has been given to mankind under the form of an infallible book. From another point of view, we may discern a certain connexion between the idea that God would be defiled by any immediate contact with the material world, and the Sabbatarianism which was so rife among Gentiles as well as among Jews at that period. For such a theory of the divine character readily associates itself with the notion that holiness excludes not only material industry but any interest the scope of which is limited to our present life.
TWO:The tender, its engine missing badly, turned its attention to the man in the water, but before it could get to him or near him Sandy, Dick and Larry saw that he caught the tail assembly of the amphibian and scrambling over the fuselage as the craft picked up speed, fell flat on his stomach just behind the pilots place and clung tightly while the craft got on the step and went into the air in a swift moil of foam and a roaring of its engine."We'll sit in the hall," said Lawrence. "We'll take it for granted that the owner is a hospitable man, and permit ourselves the luxury of tobacco."
TWO:For a half century past no considerable change has been made in engine lathes, at least no new principle of operation has been added, but many improvements have been made in their adaptation and capacity for special kinds of work. Improvements have been made in the facilities for changing wheels in screw cutting and feeding, by frictional starting gear for the carriages, an independent feed movement for turning, arrangements to adjust tools, cross feeding and so on, adding something, no doubt, to the efficiency of lathes; but the improvements named have been mainly directed to supplanting the skill of lathemen.This is one theory of the principle upon which the Barker wheel operates, which has been laid down in Vogdes' "Mensuration," and perhaps elsewhere. The other theory alluded to is that, direct action and reaction being equal, ponderable matter discharged tangentally from the periphery of a wheel must create a reactive force equal to the direct force with which the weight is thrown off. To state it more plainly, the spouting water that issues from the arm of a Barker wheel must react in the opposite course in proportion to its weight.
