TWO:We have here, indeed, something comparable not only to the scepticism of the New Academy, but also to the Aristotelian criticism of Platos metaphysics; and, at first sight, it might seem as if the Peripatetic philosophy was destined once more to regain the position taken from it by the resuscitation of its ancient foe. But Locke was not inclined to substitute one form of scholasticism for another. By applying the analytical method of Atomism to knowledge itself, he created a weapon equally fatal to the two competing systems. Under his dissection, the concrete individual substance of the one vanished no less completely than the universal ideas of the other. Nothing remained but a bundle of qualities held together by a subjective bond.
FORE:"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."
FORE:What without sin we may aspire to know.22The two elements of error and achievement are so intimately blended and mutually conditioned in the philosophy which we have been reviewing, that to decide on their respective importance is impossible without first deciding on a still larger questionthe value of systematic thought as such, and apart from its actual content. For Aristotle was perhaps the greatest master of systematisation that ever lived. The401 framework and language of science are still, to a great extent, what he made them; and it remains to be seen whether they will ever be completely remodelled. Yet even this gift has not been an unmixed benefit, for it was long used in the service of false doctrines, and it still induces critics to read into the Aristotelian forms truths which they do not really contain. Let us conclude by observing that of all the ancients, or even of all thinkers before the eighteenth century, there is none to whom the methods and results of modern science could so easily be explained. While finding that they reversed his own most cherished convictions on every point, he would still be prepared by his logical studies to appreciate the evidence on which they rest, and by his ardent love of truth to accept them without reserve. Most of all would he welcome our astronomy and our biology with wonder and delight, while viewing the development of modern machinery with much more qualified admiration, and the progress of democracy perhaps with suspicious fear. He who thought that the mind and body of an artisan were alike debased by the exercise of some simple handicraft under the pure bright sky of Greece, what would he have said to the effect wrought on human beings by the noisome, grinding, sunless, soulless drudgery of our factories and mines! How profoundly unfitted would he have deemed its victims to influence those political issues with which the interests of science are every day becoming more vitally connected! Yet slowly, perhaps, and unwillingly, he might be brought to perceive that our industry has been the indispensable basis of our knowledge, as supplying both the material means and the moral ends of its cultivation. He might also learn that there is an even closer relationship between the two: that while the supporters of privilege are leagued for the maintenance of superstition, the workers, and those who advocate their claims to political equality, are leagued for its restraint and overthrow. And if402 he still shrank back from the heat and smoke and turmoil amid which the genius of our age stands, like another Heracleitus, in feverish excitement, by the steam-furnace whence its powers of revolutionary transmutation are derived, we too might reapply the words of the old Ephesian prophet, bidding him enter boldly, for here also there are gods.
FORE:Pencil-work is indeed the main operation, the inking being merely to give distinctness and permanency to the lines. The main thing in pencilling is accuracy of dimensions and stopping the lines where they should terminate without crossing others. The best pencils only are suitable for draughting; if the plumbago is not of the best quality, the points require to be continually sharpened, and the pencil is worn away at a rate that more than makes up the difference in cost between the finer and cheaper grades of pencils, to say nothing of the effect upon a drawing.

THREE:"And then the disaster followed suddenly. At about five o'clock a tremendous explosion shook the fort to the foundations; the powder-magazine had caught fire. It is impossible to describe the appalling results of that explosion; the entire middle-part of the fort collapsed in a stupendous cloud of flames, smoke and dust; it was an awful destruction, an immense avalanche of masses of concrete, fragments of armour, which in their fall crushed to death nearly the whole of the garrison. From this fantastical, confused mass, overwhelming clouds of suffocating smoke escaped through some crevices and holes.
THREE:In no other branch of machinery has so much research and experiment been made during eighty years past as in steam machinery, and, strange to say, the greater part of this research has been directed to the details of engines; yet there has been no improvement made during the time which has effected any considerable saving of heat or expense. The steam-engines of fifty years ago, considered as steam-using machines, utilised nearly the same proportion of the energy or power developed by the boiler as the most improved engines of modern constructiona fact that in itself indicates that an engine is not the vital part of steam machinery. There is not the least doubt that if the efforts to improve steam-engines had been mainly directed to economising heat and increasing the evaporative power of boilers, much more would have been accomplished with the same amount of research. This remark, however, does not apply to the present day, when the principles of steam-power are so well understood, and when heat is recognised as the proper element to deal with in attempts to diminish the expense of power. There is, of course, various degrees of economy in steam-using as well as in steam-generating machinery; but so long as the best steam machinery does not utilise but one-tenth or one-fifteenth part of the heat represented in the fuel burned, there need be no question as to the point where improvements in such machinery should be mainly directed.
THREE:The driver was clad in goggles and leather coat, thereby proclaiming the fact that he was used to a high rate of speed. He placed a note in Bruce's hand; there was an interrogative gleam in his eyes.The De Rerum Natura is the greatest of Roman poems, because it is just the one work where the abstract genius of Rome met with a subject combining an abstract form with the interest and inspiration of concrete reality; where negation works with a greater power than assertion; where the satire is directed against follies more wide-spread and enduring than any others; where the teaching in some most essential points can never be superseded; and where dependence on a Greek model left the poet free to contribute from his own imagination those elements to which the poetic value of his work is entirely due. By a curious coincidence, the great poet of mediaeval Italy attained success by the employment of a somewhat similar method. Dante represented, it is true, in their victorious combination, three influences against which Lucretius waged an unrelenting warfarereligion, the idealising love of woman, and the spiritualistic philosophy of Greece. Nevertheless, they resemble each other in this important particular, that both have taken an114 abstract theory of the world as the mould into which the burning metal of their imaginative conceptions is poured. Dante, however, had a power of individual presentation which Lucretius either lacked or had no opportunity of exercising; and therefore he approaches nearer to that supreme creativeness which only two races, the Greek and the English, have hitherto displayed on a very extended scale.
