TWO: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 men��s 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 man��s highest nature, which again he identifies with the reasoning process or cognition in its purest form.As we went on towards Eerneghem French aviators were heroically reconnoitring above the German lines. One came from Dixmuiden and one from Nieuwpoort; both went to about half-way between these two towns, where the centre of the battle was. The Germans kept up an unbroken artillery fire at those birds in the air. I saw quite near to them shells exploding right and left and discharging dense, black clouds of smoke that disappeared slowly. There were moments when these black stretches of cloud seemed to form a frame round the aeroplanes, but the brave aviators knew how to escape from their assailants by all sorts of tricks. They came down to go up again unexpectedly, entirely changed their direction a moment later, and at last both disappeared undamaged.

TWO:The fascination exercised by Plotinus was not only intellectual, but personal. Singularly affable, obliging, and patient, he was always ready to answer the questions of his friends, even laying aside his work in order to discuss the difficulties which they brought to him for solution. His lectures were given in Greek; and although this always remained to him a foreign language, the pronunciation and grammar of which he never completely mastered, his expressions frequently won admiration by their felicity and force; and the effect of his eloquence was still further heightened by the glowing enthusiasm which irradiated his whole countenance, naturally a very pleasing one, during the delivery of the more impressive passages.410

TWO:The valve gearing of automatic steam-hammers to fill the two conditions of allowing a dead or an elastic blow, furnishes one of the most interesting examples of mechanical combination.

TWO:The foregoing record of my experiences in Louvain will make it sufficiently clear to the unprejudiced reader that the destruction and wholesale murders were nothing but wanton crimes committed by the German troops stationed there, crimes which it is impossible to justify on any ground.

TWO:Death was near parting them now if the gleam in Leona Lalage's eyes meant anything. She would have given half her splendour, years of her life, to see that man lying dead at her feet. If she could have slain him and safely disposed of his body she would have done so.

TWO:Agreeing in the sound, not in the sense.

TWO:3. The vertical movement of material, although it consumes more power, is more economical than horizontal handling, because less floor room and ground surface is required."What, the diamonds that have caused all this trouble to get. Never!"

TWO:"Oh, but listen: my papers...."Writers on mechanical subjects, as a rule, have only theoretical knowledge, and consequently seldom deal with workshop processes. Practical engineers who have passed through a successful experience and gained that knowledge which is most difficult for apprentices to acquire, have generally neither inclination nor incentives to write books. The changes in manipulation are so frequent, and the operations so diversified, that practical men have a dread of the criticisms which such changes and the differences of opinion may bring forth; to this may be added, that to become a practical mechanical engineer consumes too great a share of one's life to leave time for other qualifications required in preparing books. For these reasons "manipulation" has been neglected, and for the same reasons must be imperfectly treated here. The purpose is not so much to instruct in shop processes as to point out how they can be best learned, the reader for the most part exercising his own judgment and reasoning powers. It will be attempted to point out how each simple operation is governed by some general principle, and how from such operations, by tracing out the principle which lies at the bottom, it is possible to deduce logical conclusions as to what is right or wrong, expedient or inexpedient. In this way, it is thought, can [6] be established a closer connection between theory and practice, and a learner be brought to realise that he has only his reasoning powers to rely on; that formul?, rules, tables, and even books, are only aids to this reasoning power, which alone can master and combine the symbol and the substance.
