TWO:There is no use in entering upon detailed explanations of what a learner has before him. Shafts are seen wherever there is machinery; it is easy to see the extent to which they are employed to transmit power, and the usual manner of arranging them. Various text-books afford data for determining the amount of torsional strain that shafts of a given diameter will bear; explain that their capacity to resist torsional strain is as the cube of the diameter, and that the deflection from transverse strains is so many degrees; with many other matters that are highly useful and proper to know. I will therefore not devote any space to these things here, but notice some of the more obscure conditions that pertain to shafts, such as are demonstrated by practical experience rather than deduced from mathematical data. What is said will apply especially to what is called line-shafting for conveying and distributing power in machine-shops and other manufacturing establishments. The following propositions in reference to shafts will assist in understanding what is to follow:��She sat down quietly for a moment with her hands locked together. That indomitable will was acting on the racked body. She crept upstairs before dinner white and shaky; she came down shimmering in white, and diamonds in her magnificent hair and corsage, smiling, brilliant, as if she had the whole world at her feet. Hetty looked at her with dazed admiration.

TWO:We have, thirdly, to consider a form of individualism249 directly opposed in character to those already specified. It is the complete withdrawal from public affairs for the sake of attending exclusively to one��s private duties or pleasures. Such individualism is the characteristic weakness of conservatives, who are, by their very nature, the party of timidity and quiescence. To them was addressed the exhortation of Cato, capessenda est respublica. The two other forms of which we have spoken are, on the contrary, diseases of liberalism. We see them exemplified when the leaders of a party are harassed by the perpetual criticism of their professed supporters; or, again, when an election is lost because the votes of the Liberal electors are divided among several candidates. But when a party��generally the Conservative party��loses an election because its voters will not go to the poll, that is owing to the lazy individualism which shuns political contests altogether. It was of this disease that the public life of Athens really perished; and, so far, Hegel is on the right track; but although its action was more obviously and immediately fatal in antiquity, we are by no means safe from a repetition of the same experience in modern society. Nor can it be said that Plato reacted against an evil which, in his eyes, was an evil only when it deprived a very few properly-qualified persons of political supremacy. With regard to all others he proposed to sanction and systematise what was already becoming a common custom��namely, entire withdrawal from the administration of affairs in peace and war. Hegel seems to forget that it is only a single class, and that the smallest, in Plato��s republic which is not allowed to have any private interests; while the industrial classes, necessarily forming a large majority of the whole population, are not only suffered to retain their property and their families, but are altogether thrown back for mental occupation on the interests arising out of these. The resulting state of things would have found its best parallel, not in old Greek city life, but in modern Europe, as it was between the Reformation and the French Revolution.

TWO:Isometrical perspective is often useful in drawing, especially in wood structures, when the material is of rectangular section, and disposed at right angles, as in machine frames. One isometrical view, which can be made nearly as quickly as a true elevation, will show all the parts, and may be figured for dimensions the same as plane views. True perspective, although rarely necessary in mechanical drawing, may be studied with advantage in connection with geometry; it will often lead to the explanation of problems in isometric drawing, and will also assist in free-hand lines that have sometimes to be made to show parts of machinery oblique to the regular planes. Thus far the remarks on draughting have been confined to manipulation mainly. As a branch of engineering work, draughting must depend mainly on special knowledge, and is not capable of being learned or practised upon general principles or rules. It is therefore impossible to give a learner much aid by searching after principles to guide him; the few propositions that follow comprehend nearly all that may be explained in words.

TWO:��We��re off!�� exulted Dick.

TWO:A bevel square is often convenient, but should be an independent one; a T square that has a movable blade is not suitable for general use. Combinations in draughting instruments, no matter what their character, should be avoided; such combinations, like those in machinery, are generally mistakes, and their effect the reverse of what is intended.The older pilot, staring at his accuser for an instant, as though hesitating about some sharp response, suddenly began to chuckle.

TWO:Some uphold the accusation on the ground of expressions in Belgian newspapers, collected in a German pamphlet. In my opinion these quotations have not the slightest value. Everyone will understand this who thinks of the excitement of journalists, whose country was suddenly and quite unexpectedly involved in a terrible war, and who felt now that as journalists they had to perform a great, patriotic duty. In their nervous, over-excited condition they sat at their desk and listened to the gossip of refugees about civilians taking part in the struggle. In their imagination they saw hordes of barbarians overrun their native soil, saw man and man, woman88 and woman, shoulder to shoulder, resisting the invader without regard for their own life. The thoughts of such journalists, whose very own country had been at war now for a few days, were not on severe logical lines; they found a certain beauty in that picture, and I can quite understand how some came to believe in it as a reality, and gloried in it."It's all right," he said. "I have had Balmayne here as you suggested. And I have told him exactly as much as you desired him to know. He's just gone off in a great hurry, for any money to Lytton Avenue."

TWO:Thus we find Pyrrho competing with the dogmatists as a practical moralist, and offering to secure the inward tranquillity at which they too aimed by an easier method than theirs. The last eminent representative of the sceptical school, Sextus Empiricus, illustrates its pretensions in this respect by the well-known story of Apelles, who, after vainly endeavouring to paint the foam on a horse��s mouth, took the sponge which he used to wipe his easel, and threw it at the picture in vexation. The mixture of colours thus accidentally applied produced the exact effect which he desired, but at which no calculation could arrive. In like manner, says Sextus, the confusion of universal doubt accidentally resulted in the imperturbability which accompanies suspense of judgment as surely as a body is followed by its shadow.229 There was, however, no accident about the matter at all. The abandonment of those studies which related to the external world was a consequence of the ever-increasing attention paid to human interests, and that these could be best consulted by complete detachment from outward circumstances, was a conclusion inevitably suggested by the negative or antithetical moment of Greek thought. Hence, while the individualistic and apathetic tendencies of the age were shared by every philosophical school, they had a closer logical connexion with the idealistic than with the naturalistic method; and so it is among the successors of Protagoras that we find them developed with the greatest distinctness; while their incorporation with142 Stoicism imposed a self-contradictory strain on that system which it never succeeded in shaking off. Epicureanism occupied a position midway between the two extremes; and from this point of view, we shall be better able to understand both its inherent weakness as compared with the other ancient philosophies, and the admiration which it has attracted from opposite quarters in recent years. To some it is most interesting as a revelation of law in Nature, to others as a message of deliverance to man��not merely a deliverance from ignorance and passion, such as its rivals had promised, but from all established systems, whether religious, political, or scientific. And unquestionably Epicurus did endeavour to combine both points of view in his theory of life. In seeking to base morality on a knowledge of natural law he resembles the Stoics. In his attacks on fatalism, in his refusal to be bound down by a rigorously scientific explanation of phenomena, in his failure to recognise the unity and power of Nature, and in his preference of sense to reason, he partially reproduces the negative side of Scepticism; in his identification of happiness with the tranquil and imperturbable self-possession of mind, in his mild humanism, and in his compliance with the established religion of the land, he entirely reproduces its positive ethical teaching. On the other hand, the two sides of his philosophy, so far from completing, interfere with and mar one another. Emancipation from the outward world would have been far more effectually obtained by a total rejection of physical science than by the construction of a theory whose details were, on any scientific principles, demonstrably untrue. The appeal to natural instinct as an argument for hedonism would, consistently followed out, have led to one of two conclusions, either of which is incompatible with the principle that imperturbability is the highest good. If natural instinct, as manifested by brutes, by children, and by savages, be the one sure guide of action, then Callicles was right, and the habitual143 indulgence of passion is wiser than its systematic restraint. But if Nature is to be studied on a more specific and discriminating plan, if there are human as distinguished from merely animal impulses, and if the higher development of these should be our rule of life, then Plato and Aristotle and the Stoics were right, and the rational faculties should be cultivated for their own sake, not because of the immunity from superstitious terrors which they secure. And we may add that the attendance on public worship practised by Epicurus agreed much better with the sceptical suspense of judgment touching divine providence than with its absolute negation, whether accompanied or not by a belief in gods who are indifferent to sacrifice and prayer.

TWO:Finally, in man himself, thought is not distinguished from feeling; it is, in fact, the essence of mind, just as extension is the essence of body; and all spiritual phenomena are modes of thought in the same sense that all physical phenomena are modes of space. It was, then, rather a happy chance than genuine physiological insight which led Descartes to make brain the organ of feeling no less than of intellection; a view, as Prof. Huxley has observed, much in advance of that held by Bichat a hundred and fifty years later. For whoever deduced all the mental manifestations from a common essence was bound in consistency to locate them in the same bodily organ; what the metaphysician had joined the physiologist could not possibly put asunder.
