TWO:On the other hand, the amount that an apprentice may earn by his labour is governed by his natural capacity, and by the interest he may feel in advancing; also from the view he may take of the equity of his engagement, and the estimate that he places upon the privileges and instruction that he receives. In many branches of business, where the nature of the operations carried on are measurably uniform, and have not for a long time been much affected by changes and improvements, the conditions of apprenticeship are more easy to define; but mechanical engineering is the reverse of this, it lacks uniformity both as to practice and what is produced. To estimate the actual value of apprentice labour in an engineering-work is not only a very difficult matter, but to some extent impracticable even by those of long experience and skilled in such investigations; and it is not to be expected that a beginner will under such circumstances be able to understand the value of such labour: he is generally led to the conclusion that he is unfairly treated, that his services are not sufficiently paid for, and that he is not advanced rapidly enough."De Tijd, sir; here is my press-card."

TWO:Finally, while the attempt to attain extreme accuracy of definition was leading to the destruction of all thought and all reality within the Socratic school, the dialectic method had been taken up and parodied in a very coarse style by a class of persons called Eristics. These men had, to some extent, usurped the place of the elder Sophists as paid instructors of youth; but their only accomplishment was to upset every possible assertion by a series of verbal juggles. One of their favourite paradoxes was to deny the reality of falsehood on the Parmenidean principle that ��nothing cannot exist.�� Plato satirises their method in the Euthyd��mus, and makes a much more serious attempt to meet it in the Sophist; two Dialogues which seem to have been composed not far from one another.156 The Sophist effects a considerable simplification in the ideal theory by resolving negation into difference, and altogether omitting the notions of unity and plurality,��perhaps as a result of the investiga265tions contained in the Parmenides, another dialogue belonging to the same group, where the couple referred to are analysed with great minuteness, and are shown to be infected with numerous self-contradictions. The remaining five ideas of Existence, Sameness, Difference, Rest, and Motion, are allowed to stand; but the fact of their inseparable connexion is brought out with great force and clearness. The enquiry is one of considerable interest, including, as it does, the earliest known analysis of predication, and forming an indispensable link in the transition from Platonic to Aristotelian logic��that is to say, from the theory of definition and classification to the theory of syllogism."Industry, trade, and agriculture exist no longer, labour is unemployed, and food is getting scarce, and over this dismal scene hovers the memory of numerous victims, of hundreds of prisoners of war or missing soldiers. During the bombardment of August 23rd one hundred persons were killed outright, or succumbed to their wounds. There are innumerable other wounded. This it is plain must have plunged the town into deep distress.

TWO:A modern turbine water-wheel, one of the best construction, operating under favourable conditions, gives a percentage of the power of the water which, after deducting the friction of the wheel, almost reaches the theoretical coefficient or equals the gravity of the water; it may therefore be assumed that there will in the future be but little improvement made in such water-wheels except in the way of simplifying and cheapening their construction. There is, in fact, no other class of machines which seem to have reached the same state of improvement as water-wheels, nor any other class of machinery that is constructed with as much uniformity of design and arrangement, in different countries, and by different makers.No reply for a moment, nothing but a quick heaving of the broad bosom, a livid play like summer lightning in the dark eyes. The man lighted a cigarette and puffed it noisily.

TWO:5. The lubrication of surfaces working under air pressure, such as the pistons and valves of engines.Designing machines must have reference to adaptation, endurance, and the expense of construction. Adaptation includes the performance of machinery, its commercial value, or what the machinery may earn in operating; endurance, the time that machines may operate without being repaired, and the constancy of their performance; expense, the investment represented in machinery.

TWO:CHAPTER XXXIX. DESIGNING MACHINES.What happened at Landen made a very deep222 impression upon me; it shocked me more than all the terrible things which I had seen during the war and all the dangers which I went through. When the train went on again, and the soldiers began to speak to me once more, I was unable to utter a word and sat there musing.

TWO:In point of style, Plotinus is much the most difficult of the ancient philosophers, and, in this respect, is only surpassed by a very few of the moderns. Even Longinus, who was one of the most intelligent critics then living, and who, besides,283 had been educated in the same school with our philosopher, could not make head or tail of his books when copies of them were sent to him by Porphyry, and supposed, after the manner of philologists, that the text must be corrupt, much to the disgust of Porphyry, who assures us that its accuracy was unimpeachable.426 Probably politeness prevented Longinus from saying, what he must have seen at a glance, that Plotinus was a total stranger to the art of literary composition. We are told that he wrote as fast as if he were copying from a book; but he had never mastered even the elements of the Greek language; and the weakness of his eyesight prevented him from reading over what he had written. The mistakes in spelling and grammar Porphyry corrected, but it is evident that he has made no alterations in the general style of the Enneads; and this is nearly as bad as bad can be��disjointed, elliptical, redundant, and awkward. Chapter follows chapter and paragraph succeeds to paragraph without any fixed principle of arrangement; the connexion of the sentences is by no means clear; some sentences are almost unintelligible from their extreme brevity, others from their inordinate length and complexity. The unpractised hand of a foreigner constantly reveals itself in the choice and collocation of words and grammatical inflections. Predicates and subjects are huddled together without any regard to the harmonies of number and gender, so that even if false concords do not occur, we are continually annoyed by the suggestion of their presence.427

TWO:No more wounded were taken to the hospitals of Louvain, as it had been decided to send them straight on to Germany for the present; yet there were many wounded men who were being nursed there already, and the doctors had their hands full attending to the wounded who passed the town. Dr. Noyons told me that the previous Sunday a train with 600 wounded had arrived from Northern France, and he and his assistants had been requested "just" to dress the wounds again of some of them. The condition of these unfortunate men must have been awful; not one had a dressing less than eight days old. Most of them had had it on much longer,209 and then these were merely emergency dressings. They were laid on straw in cattle trucks, many of them even in filth, and infection had worsened their condition to a great extent. Dr. Noyons and his colleagues tried to give the poor fellows as much relief as possible, but as a matter of course they could not do very much during a short stay at a station.

TWO:It has been shown how universal space and universal thought at once contain and explain each particular space and each particular concept. In like manner, the infinite substance contains and explains space and thought themselves. Contains them, yes, as attributes; but explains them, how? As two among an infinity of attributes. In other words, if we ask why there should be such an existence as space, the answer is because existence, being infinite, must necessarily include every conceivable thing. The argument is strikingly like a principle of the Epicurean philosophy, and may well have been suggested by it. According to Lucretius, the appearance of design in our world need not be attributed to creative intelligence, because infinite atoms moving in infinite manners through infinite time, must at length arrive, after a comprehensive series of experiments, at the present frame of things;562 and the same principle is invoked on a smaller scale to account for the origin of organised beings, of memory, and of civil society.563 In both systems, infinite space is the root-conception; but what Lucretius had legitimately used to explain becoming, Spinoza illegitimately applies to the elucidation of being. At one stroke all empirical knowledge is placed on an �� priori foundation. By assuming unlimited credit at the bank of the universe we entitle ourselves to draw a cheque for any particular amount. Thus the idea of infinite attributes is no mere collateral speculation, but forms an407 essential element of Spinozism. The known varieties of existence are, so to speak, surrounded, supported, and fixed in their places by the endless multitude of the unknown. And this conception of being as absolutely infinite, is another proof of Spinoza��s Platonic tendencies, for it involves the realisation of an abstract idea, that is to say, of Being, which the philosopher treats as something more comprehensive than the facts of consciousness whence it is derived.
