THREE:
THREE:The traction of belts upon pulleys, like that of locomotive wheels upon railways, being incapable of demonstration except by actual experience, for a long time hindered the introduction of belts as a means of transmitting motion and power except in cases when gearing or shafts could not be employed. Motion is named separately, because with many kinds of machinery that are driven at high speedsuch as wood machinesthe transmission of rapid movement must be considered as well as power, and in ordinary practice it is only by means of belts that such high speeds may be communicated from one shaft to another.
THREE:Yet there was a difference between them, marking off each as the head of a whole School much wider than the Academy or the Lyceum; a difference which we can best express by saying that Plato was pre-eminently a practical, Aristotle pre-eminently a speculative genius. The object of the one was to reorganise all human life, that of the other to reorganise all human knowledge. Had the one lived earlier, he would more probably have been a great statesman or a great general than a great writer; the other would at no time have been anything but a philosopher, a mathematician, or a historian. Even from birth they seemed to be respectively marked out for an active and for a contemplative life: the one, a citizen of the foremost State in Hellas, sprung from a family in which political ambition was hereditary, himself strong, beautiful, fascinating, eloquent, and gifted with the keenest insight into mens capacities and motives; the other a Stagirite and an Asclepiad, that is to say, without opportunities for a public career, and possessing a hereditary aptitude for anatomy and natural history, fitted by his insignificant person and delicate constitution for sedentary pursuits, and better able to acquire a knowledge even of human nature from books than from a living converse with men and affairs. Of course, we are not for a moment denying to Plato a fore294most place among the masters of those who know; he embraced all the science of his age, and to a great extent marked out the course which the science of future ages was to pursue; nevertheless, for him, knowledge was not so much an end in itself as a means for the attainment of other ends, among which the preservation of the State seems to have been, in his eyes, the most important.M Aristotle, on the other hand, after declaring happiness to be the supreme end, defines it as an energising of mans highest nature, which again he identifies with the reasoning process or cognition in its purest form.
TWO:A queer sort of fainting fit had been followed by a ghastly sense of fear. Intrigue had hitherto been the very air that this woman breathed. Now she was frightened, every ring of the bell sent her heart into her mouth.The auxiliary departments, if disposed about an erecting shop in the centre, should be so arranged that material which has to pass through two or more departments can do so in the order of the processes, and without having to cross the erecting shop. Casting, boring, planing, drilling, and fitting, for example, should follow each other, and the different departments be arranged accordingly; whenever a casting is moved twice over the same course, it shows fault of arrangement and useless expense. The same rule applies to all kinds of material.
TWO:Unless some unforeseen event took place she had saved her own life. But all the same there was danger. The police would probably get Ren, but also they might get her, which was a much more serious matter. She softly opened the catch of the back drawing-room window so that she could reach the garden.
