ONE:So far, we have spoken as if the Socratic definitions were merely verbal; they were, however, a great deal more, and their author did not accurately discriminate between what at that stage of thought could not well be kept apart��explanations of words, practical reforms, and scientific generalisations. For example, in defining a ruler to be one who knew more than other men, he was departing from the common usages of language, and showing not what was, but what ought to be true.93 And in defining virtue as wisdom, he was putting forward a new theory of his own, instead of formulating the145 received connotation of a term. Still, after making every deduction, we cannot fail to perceive what an immense service was rendered to exact thought by introducing definitions of every kind into that department of enquiry where they were chiefly needed. We may observe also that a general law of Greek intelligence was here realising itself in a new direction. The need of accurate determination had always been felt, but hitherto it had worked under the more elementary forms of time, space, and causality, or, to employ the higher generalisation of modern psychology, under the form of contiguous association. The earlier cosmologies were all processes of circumscription; they were attempts to fix the limits of the universe, and, accordingly, that element which was supposed to surround the others was also conceived as their producing cause, or else (in the theory of Heracleitus) as typifying the rationale of their continuous transformation. For this reason Parmenides, when he identified existence with extension, found himself obliged to declare that extension was necessarily limited. Of all the physical thinkers, Anaxagoras, who immediately precedes Socrates, approaches, on the objective side, most nearly to his standpoint. For the governing Nous brings order out of chaos by segregating the confused elements, by separating the unlike and drawing the like together, which is precisely what definition does for our conceptions. Meanwhile Greek literature had been performing the same task in a more restricted province, first fixing events according to their geographical and historical positions, then assigning to each its proper cause, then, as Thucydides does, isolating the most important groups of events from their external connexions, and analysing the causes of complex changes into different classes of antecedents. The final revolution effected by Socrates was to substitute arrangement by difference and resemblance for arrangement by contiguity in coexistence and succession. To say that by so doing he created science is inexact, for science requires to consider nature under every146 aspect, including those which he systematically neglected; but we may say that he introduced the method which is most particularly applicable to mental phenomena, the method of ideal analysis, classification, and reasoning. For, be it observed that Socrates did not limit himself to searching for the One in the Many, he also, and perhaps more habitually, sought for the Many in the One. He would take hold of a conception and analyse it into its various notes, laying them, as it were, piecemeal before his interlocutor for separate acceptance or rejection. If, for example, they could not agree about the relative merits of two citizens, Socrates would decompose the character of a good citizen into its component parts and bring the comparison down to them. A good citizen, he would say, increases the national resources by his administration of the finances, defeats the enemy abroad, wins allies by his diplomacy, appeases dissension by his eloquence at home.94 When the shy and gifted Charmides shrank from addressing a public audience on public questions, Socrates strove to overcome his nervousness by mercilessly subdividing the august Eccl��sia into its constituent classes. ��Is it the fullers that you are afraid of?�� he asked, ��or the leather-cutters, or the masons, or the smiths, or the husbandmen, or the traders, or the lowest class of hucksters?��95 Here the analytical power of Greek thought is manifested with still more searching effect than when it was applied to space and motion by Zeno.Good fitting is often not so much a question of skill as of the standard which a workman has fixed in his mind, and to which all that he does will more or less conform. If this standard is one of exactness and precision, all that is performed, whether it be filing, turning, planing, or drawing, will come to this standard. This faculty of mind can be defined no further than to say that it is an aversion to whatever is imperfect, and a love for what [171] is exact and precise. There is no faculty which has so much to do with success in mechanical pursuits, nor is there any trait more susceptible of cultivation. Methodical exactness, reasoning, and persistence are the powers which lead to proficiency in engineering pursuits.

ONE:"Mamie," Hetty said simply. "The child has been greatly frightened. She is calling for you. Will you please go up at once?"

TWO:"What a luminous mind yours is," Lawrence replied. "That's just why I did come. As you know, I am deeply interested in clearing up the Corner House mystery. I've got nearer to it than anybody imagines. Do you happen to have any idea who came with those particular notes last night?"

High-purity distillation system

High quality is being demanded in many fields nowadays and so in order to satisfy that we developed a high-purity distillation system in collaboration with Ube industries, Ltd. and Kanto Chemical Co., Inc. The system is used to refine cleaning solutions for the semiconductor industry, medical materials, etc. of high purity (residual ion concentration: 0.01 to 1.0 ppb).

THREE:The philosophical affinities of the new science were not exhausted by the atomistic analysis of Democritus and the regulative method of Aristotle. Platonism could hardly fail to benefit by the great impulse given to mathematical studies in the latter half of the sixteenth century. The passionate love of its founder for geometry must have recommended him as much to the most advanced minds of the period as his religious mysticism had recommended him to the theologians of the earlier Renaissance. And the increasing ascendency of the heliocentric astronomy, with its splendid defiance of sense and opinion, was indirectly a triumph for the philosophy which, more than any other, had asserted the claims of pure reason against both. We see this distinctly in Galileo. In express adhesion to Platonism, he throws his teaching into a conversational form, endeavouring to extract the truth from his opponents rather than convey it into their minds from without; and the theory of reminiscence as the source of demonstrative knowledge seems to meet with his approval.549 He is always ready with proofs drawn from observation and experiment; but nothing can be more in Plato��s spirit, nothing more unlike Aristotle and Bacon, than his encomium on the sublime genius of Aristarchus and Copernicus for having maintained a rational hypothesis against what seemed to be the evidence of their senses.550 And he elsewhere observes how much less would have been the glory of Copernicus had he known the experimental verification of his theory.551Machinery can be divided into four classes, each constituting a division that is very clearly defined by functions performed, as follows:��

Our High-purity distillation system provide our clients with high solvent recovery rate, almost 100%.
The quality of the products/output from our system is very stable, which makes production management very easy, and easier than the conventional ion exchange resin method.
No emission of waste brings our clients reduction of running cost for environmental measures.
Our various devices minimize entrainment.
To prevent the elution of metal, you could ask us the system made of Teflon.
Our High-purity distillation system has been already proved for solvents that trigger very rapid decomposition reactions, such as hydrogen peroxide.
