TWO:A Hellene, and an aristocrat as well. Or, using the word in its most comprehensive sense, we may say that he was an aristocrat all round, a believer in inherent superiorities of race, sex, birth, breeding, and age. Everywhere we find him restlessly searching after the wisest, purest, best, until at last, passing beyond the limits of existence itself, words fail him to describe the absolute ineffable only good, not being and not knowledge, but creating and inspiring both. Thus it came to pass that his hopes of effecting a thorough reform did not lie in an appeal to the masses, but in the selection and198 seclusion from evil influences of a few intelligent youths. Here we may detect a remarkable divergence between him and his master. Socrates, himself a man of the people, did not like to hear the Athenians abused. If they went wrong, it was, he said, the fault of their leaders.126 But according to Plato, it was from the people themselves that corruption originally proceeded, it was they who instilled false lessons into the most intelligent minds, teaching them from their very infancy to prefer show to substance, success to merit, and pleasure to virtue; making the study of popular caprice the sure road to power, and poisoning the very sources of morality by circulating blasphemous stories about the godsstories which represented them as weak, sensual, capricious beings, setting an example of iniquity themselves, and quite willing to pardon it in men on condition of going shares in the spoil. The poets had a great deal to do with the manufacture of these discreditable myths; and towards poets as a class Plato entertained feelings of mingled admiration and contempt. As an artist, he was powerfully attracted by the beauty of their works; as a theologian, he believed them to be the channels of divine inspiration, and sometimes also the guardians of a sacred tradition; but as a critic, he was shocked at their incapacity to explain the meaning of their own works, especially when it was coupled with ridiculous pretensions to omniscience; and he regarded the imitative character of their productions as illustrating, in a particularly flagrant manner, that substitution of appearance for reality which, according to his philosophy, was the deepest source of error and evil.The other alternative was to combine the dialectical idealism of Plato with the cosmology of early Greek thought, interpreting the two worlds of spirit and Nature as gradations of a single series and manifestations of a single principle. This was what Aristotle had attempted to do, but had not done so thoroughly as to satisfy the moral wants of his own age, or the religious wants of the age when a revived Platonism was seeking to organise itself into a system which should be the reconciliation of reason and faith. Yet the better sort of Platonists felt that this work could not be accomplished without the assistance of Aristotle, whose essential agreement with their master, as against Stoicism, they fully recognised. Their273 mistake was to assume that this agreement extended to every point of his teaching. Taken in this sense, their attempted harmonies were speedily demolished by scholars whose professional familiarity with the original sources showed them how strongly Aristotle himself had insisted on the differences which separated him from the Academy and its founder.407 To identify the two great spiritualist philosophers being impossible, it remained to show how they could be combined. The solution of such a problem demanded more genius than was likely to be developed in the schools of Athens. An intenser intellectual life prevailed in Alexandria, where the materials of erudition were more abundantly supplied, and where contact with the Oriental religions gave Hellenism a fuller consciousness of its distinction from and superiority to every other form of speculative activity. And here, accordingly, the fundamental idea of Neo-Platonism was conceived.

Hydrocyclone (liquid cyclone)02

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:So far as he can be said to have studied science at all, the motive of Epicurus was hatred for religion far more than love for natural law. He seems, indeed, to have preserved that aversion for Nature which is so characteristic of the earlier Greek Humanists. He seems to have imagined that by refusing to tie himself down to any one explanation of external phenomena, he could diminish their hold over the mind of man. For when he departs from his usual attitude of suspense and reserve, it is to declare dogmatically that the heavenly bodies are no larger than they appear to our senses, and perhaps smaller than they sometimes appear.170 The only88 arguments adduced on behalf of this outrageous assertion were that if their superficial extension was altered by transmission, their colour would be altered to a still greater degree; and the alleged fact that flames look the same size at all distances.171 It is evident that neither Epicurus nor Lucretius, who, as usual, transcribes him with perfect good faith, could ever have looked at one lamp-flame through another, or they would have seen that the laws of linear perspective are not suspended in the case of self-luminous bodiesa fact which does not tell much for that accurate observation supposed to have been fostered by their philosophy.172 The truth is, that Epicurus disliked the oppressive notion of a sun several times larger than the earth, and was determined not to tolerate it, be the consequences to fact and logic what they might.
