During the two centuries that ended with the close of the Peloponnesian war, a single race, weak numerically, and weakened still further by political disunion, simultaneously developed all the highest human faculties to an extent possibly rivalled but certainly not surpassed by the collective efforts of that vastly greater population which now wields the accumulated resources of modern Europe. This race, while maintaining a precarious foothold on the shores of the Mediterranean by repeated prodigies of courage and genius, contributed a new element to civilisation which has been the mainspring of all subsequent progress, but which, as it expanded into wider circles and encountered an increasing resistance from without, unavoidably lost some of the enormous elasticity that characterised its earliest and most concentrated reaction. It was the just boast of the Greek that to Asiatic refinement and Thracian valour he joined a disinterested thirst for knowledge unshared by his neighbours on either side.5 And if a contemporary of Pericles could have foreseen all that would be thought, and said, and done during2 the next twenty-three centuries of this worlds existence, at no period during that long lapse of ages, not even among the kindred Italian race, could he have found a competitor to contest with Hellas the olive crown of a nobler Olympia, the guerdon due to a unique combination of supreme excellence in every variety of intellectual exercise, in strategy, diplomacy, statesmanship; in mathematical science, architecture, plastic art, and poetry; in the severe fidelity of the historian whose paramount object is to relate facts as they have occurred, and the dexterous windings of the advocate whose interest leads him to evade or to disguise them; in the far-reaching meditations of the lonely thinker grappling with the enigmas of his own soul, and the fervid eloquence by which a multitude on whose decision hang great issues is inspired, directed, or controlled. He would not, it is true, have found any single Greek to pit against the athletes of the Renaissance; there were none who displayed that universal genius so characteristic of the greatest Tuscan artists such as Lionardo and Michael Angelo; nor, to take a much narrower range, did a single Greek writer whose compositions have come down to us excel, or even attempt to excel, in poetry and prose alike. But our imaginary prophet might have observed that such versatility better befitted a sophist like Hippias or an adventurer like Critias than an earnest master of the Pheidian type. He might have quoted Pindars sarcasm about highly educated persons who have an infinity of tastes and bring none of them to perfection;6 holding, as Plato did in the next generation, that one man can only do one thing well, he might have added that the heroes of modern art would have done much nobler work had they concentrated their powers on a single task instead of attempting half a dozen and leaving most of them incomplete.
Hurriedly the youthful Sky Patrol tumbled onto the sand, digging cotton plugs out of their ears now that the roar of the motor no longer made them essential.
FORE:Improvements, which have totally changed machine fitting during thirty years past, have been of a character to dispense in a great measure with hand skill, and supplant it with what may be termed mental skill. The mere physical effect produced by a man's hands has steadily diminished in value, until it has now almost come to be reckoned in foot-pounds; but the necessity [166] for practical knowledge instead of being diminished is increased.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.

Gnostic pessimism marks the extreme point of aberration to which Greek thought was drawn by the attraction of Oriental superstition. How it was rescued from destruction by a new systematisation of its ancient methods and results will be explained in another chapter.He stood aside politely for the woman to pass. She led the way in her imperious fashion as if they had been honoured guests of hers. She carried her dingy dress magnificently. In the drawing-room, Lawrence drew the blinds so that they could see better. The garish light of day shone on Leon Lalage's pale face, and disclosed the deep black lines under her splendid eyes. Only the flick and tremor of her lips betrayed her feelings. With her hands folded in her lap she waited.The took of triumph faded from her eyes, she had grown worn and weary. The roses were wilting on the walls, the lights were mostly down now. Hetty, looking in to see if anything was wanted, found herself driven away almost fiercely.A pressure wheel, like a steam-engine, must include running contact between water-tight surfaces, and like a rotary steam-engine, this contact is between surfaces which move at different rates of speed in the same joint, so that the wear is unequal, and increases as the speed or the distance from the axis. When it is considered that the most careful workmanship has never produced rotary engines that would surmount these difficulties in working steam, it can hardly be expected they can be overcome in using water, which is not only liable to be filled with grit and sediment, but lacks the peculiar lubricating properties [41] of steam. A rotary steam-engine is in effect the same as a pressure water-wheel, and the apprentice in studying one will fully understand the principles of the other.There were three kinds of strain mentionedtorsional, deflective, and accidental. To meet these several strains the same means have to be provided, which is a sufficient size and strength to resist them; hence it is useless to consider each of these different strains separately. If we know which of the three is greatest, and provide for that, the rest, of course, may be disregarded. This, in practice, is found to be accidental strains to which shafts are in ordinary use subjected, and they are usually made, in point of strength, far in excess of any standard that would be fixed by either torsional or transverse strain due to the regular duty performed.
