TWO:"Certainly, captain; as a matter of fact we are of the same race."It is as if the curse of drink always pursued the garrison in Louvain, for when and wherever I met German soldiers in that town, or came into touch with them, they were always drunk. That evening, also, I was glad when I arrived at the mission house, tipped the men, and got rid of them until the next day.
THREE:A new period begins with the Greek Humanists. We use this term in preference to that of Sophists, because, as has been shown, in specially dealing with the subject, half the teachers known under the latter denomination made it their business to popularise physical science and to apply it to morality, while the other half struck out an entirely different line, and founded their educational system on the express rejection of such investigations; their method being, in this respect, foreshadowed by the greatest poet of the age, who concentrates all his attention on the workings of the human mind, and followed by its greatest historian, with whom a similar study takes the place occupied by geography and natural history in the work of Herodotus. This absorption in human interests was unfavourable alike to the objects and to the methods of previous enquiry: to the former, as a diversion from the new studies; to the latter, as inconsistent with the flexibility and many-sidedness of conscious mind. Hence the true father of philosophical scepticism was Protagoras. With him, for the first time, we find full expression given to the proper sceptical attitude, which is one of suspense and indifference as opposed to absolute denial. He does not undertake to say whether the gods exist or not. He regards the real essence of Nature as unknowable, on account of the relativity which characterises all sensible impressions. And wherever opinions are divided, he undertakes to provide equally strong arguments for both sides of the question. He also anticipates the two principal tendencies exhibited by all future scepticism in its relation to practice. One is its devotion to humanity, under the double form of exclusive attention to human interests, and great mildness in the treatment of human beings. The other is a disposition to take custom and public opinion, rather than any physical or metaphysical law, for the standard and sanction of130 morality. Such scepticism might for the moment be hostile to religion; but a reconciliation was likely to be soon effected between them.Such is the mild and conciliatory mode of treatment at first adopted by Plato in dealing with the principal representative of the SophistsProtagoras. In the Dialogue which bears his name the famous humanist is presented to us as a professor of popular unsystematised morality, proving by a variety of practical arguments and ingenious illustrations that virtue can be taught, and that the preservation of social order depends upon the possibility of teaching it; but unwilling to188 go along with the reasonings by which Socrates shows the applicability of rigorously scientific principles to conduct. Plato has here taken up one side of the Socratic ethics, and developed it into a complete and self-consistent theory. The doctrine inculcated is that form of utilitarianism to which Mr. Sidgwick has given the name of egoistic hedonism. We are brought to admit that virtue is one because the various virtues reduce themselves in the last analysis to prudence. It is assumed that happiness, in the sense of pleasure and the absence of pain, is the sole end of life. Duty is identified with interest. Morality is a calculus for computing quantities of pleasure and pain, and all virtuous action is a means for securing a maximum of the one together with a minimum of the other. Ethical science is constituted; it can be taught like mathematics; and so far the Sophists are right, but they have arrived at the truth by a purely empirical process; while Socrates, who professes to know nothing, by simply following the dialectic impulse strikes out a generalisation which at once confirms and explains their position; yet from self-sufficiency or prejudice they refuse to agree with him in taking their stand on its only logical foundation.
THREE:
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.
