THREE:To conclude. The reader will understand that the difficulties and diversity of practice, in any branch of engineering, create similar or equal difficulties in explaining or reasoning about the operations; and the most that can be done in the limited space allotted here to the subject of moving material, is to point out some of the principles that should govern the construction and adaptation of handling machinery, from which the reader can take up the subject upon his own account, and follow it through the various examples that may come under notice.The 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.

THREE:III.The principal object of Platos negative criticism had been to emphasise the distinction between reality and appearance in the world without, between sense, or imagination, and reason in the human soul. True to the mediatorial spirit of Greek thought, his object now was to bridge over the seemingly impassable gulf. We must not be understood to say that these two distinct, and to some extent contrasted, tendencies correspond to two definitely divided periods of his life. It is evident that the tasks of dissection and reconstruction were often carried on conjointly, and represented two aspects of an indivisible process. But on the whole there is good reason to believe that Plato, like other men, was more inclined to pull to pieces in his youth and to build up in his later days. We are, therefore, disposed to agree with those critics who assign both the Phaedrus and the Symposium to a comparatively advanced stage of Platonic speculation. It is less easy to decide which of the two was composed first, for there seems to be a greater maturity of thought in the one and of style in the other. For our purposes it will be most convenient to consider them together.
THREE:The keynote of the whole poem is struck in its opening lines. When Venus is addressed as Natures sole guide and ruler, this, from the poets own point of view, is not true of Nature as a whole, but it is eminently true of life, whether we identify Venus with the passion through which living things are continually regenerated, or with the pleasure which is their perpetual motive and their only good. And it is equally appropriate, equally characteristic of a consummate artist, that the interest of the work should culminate in a description of107 this same passion, no longer as the source of life, but as its last outcome and full flower, yet also, when pushed to excess, the illusion by which it is most utterly disappointed and undone; and that the whole should conclude with a description of death, not as exemplified in any individual tragedy, but in such havoc as was wrought by the famous plague at Athens on man and beast alike. Again, it is by the orderly sequence of vital phenomena that Lucretius proves his first great principle, the everlasting duration and changelessness of matter. If something can come out of nothing, he asks us, why is the production of all living things attached to certain conditions of place and season and parentage, according to their several kinds? Or if a decrease in the total sum of existence be possible, whence comes the inexhaustible supply of materials needed for the continual regeneration, growth, and nourishment of animal life? It is because our senses cannot detect the particles of matter by whose withdrawal visible objects gradually waste away that the existence of extremely minute atoms is assumed; and, so far, there is also a reference to inorganic bodies; but the porosity of matter is proved by the interstitial absorption of food and the searching penetration of cold; while the necessity of a vacuum is established by the ability of fish to move through the opposing stream. The generic differences supposed to exist among the atoms are inferred from the distinctions separating not only one animal species from another, but each individual from all others of the same species. The deflection of the atoms from the line of perpendicular descent is established by the existence of human free-will. So also, the analysis which distinguishes three determinate elements in the composition of the soul finds its justification in the diverse characters of animalsthe fierceness of the lion, the placidity of the ox, and the timorousness of the deerqualities arising from the preponderance of a fiery, an a?rial, and a windy ingredient in the animating principle of each respectively. Finally, by another organic108 illustration, the atoms in general are spoken of as semina rerumseeds of things.
THREE:The meal was finished presently. Hetty caught the scent of cigarette smoke. The Countess lounged back in her chair, smoking too. She seemed perfectly self-possessed. She looked so easy and comfortable that Maitrank was filled with admiration.
