FORE:It is strange, considering the simplicity of construction and the very important office filled by machines for cutting on plane surfaces, that they were not sooner invented and applied in metal work. Many men yet working at finishing, can remember when all flat surfaces were chipped and filed, and that long after engine lathes had reached a state of efficiency and were generally employed, planing machines were not known. This is no doubt to be accounted for in the fact that reciprocal movement, except that produced by cranks or eccentrics, was unknown or regarded as impracticable for useful purposes until late years, and when finally applied it was thought impracticable to have such movements operate automatically. This may seem quite absurd to even an apprentice of the present time, yet such reciprocating movement, as a mechanical problem, is by no means so simple as it may at first appear.Euripides gives us an interesting example of the style in which this ethical application of physical science could be practised. We have seen how Eteocl��s expresses his determination to do and dare all for the sake of sovereign power. His mother, Jocast��, gently rebukes him as follows:��

FORE:Nevertheless, in each case, subjective idealism had the effect of concentrating speculation, properly so called, on ethical and practical interests. Locke struck the keynote of eighteenth century philosophy when he pronounced morality to be ��the proper science and business of mankind in general.��574 And no sooner had morality come to the front than the significance of ancient thought again made itself apparent. Whether through conscious imitation, or because the same causes brought about the same effects, ethical enquiries moved along the lines originally laid down in the schools of Athens. When rules of conduct were not directly referred to a divine revelation, they were based either on a supposed law of Nature, or on the necessities of human happiness, or on some combination of the two. Nothing is more characteristic of422 the eighteenth century than its worship of Nature. Even the theology of the age is deeply coloured by it; and with the majority of those who rejected theology it became a new religion. But this sentiment is demonstrably of Greek origin, and found its most elaborate, though not its most absolute, expression in Stoicism. The Stoics had inherited it from the Cynics, who held the faith in greater purity; and these, again, so far as we can judge, from a certain Sophistic school, some fragments of whose teaching have been preserved by Xenophon and Plato; while the first who gave wide currency to this famous abstraction was, in all probability, Heracleitus. To the Stoics, however, is due that intimate association of naturalism with teleology which meets us again in the philosophy of the last century, and even now wherever the doctrine of evolution has not been thoroughly accepted. It was assumed, in the teeth of all evidence, that Nature bears the marks of a uniformly beneficent design, that evil is exclusively of human origin, and that even human nature is essentially good when unspoiled by artificial restrictions.Movements and strains may be called two of the leading conditions upon which designs for machines are based: movements determine general dimensions, and strains determine the proportions and sizes of particular parts. Movement and strain together determine the nature and area of bearings or bearing surfaces.

FORE:We have already observed that Scepticism among the ancients was often cultivated in connexion with some positive doctrine which it indirectly served to recommend. In the case of its last supporters, this was the study of medicine on an empirical as opposed to a deductive method. The Sceptical contention is that we cannot go beyond appearances; the empirical contention is, that all knowledge comes to us from experience, and that this only shows us how phenomena are related to one another, not how they are related to their underlying causes, whether efficient or final. These allied points of view have been brought into still more intimate association by modern thought, which, as will be shown in the concluding chapter, has sprung from a modified form of the ancient Scepticism, powerfully aided by a simultaneous development of physical science. At the same time, the new school have succeeded in shaking off the narrowness and timidity of their predecessors, who were still so far under the influence of the old dogmatists as to believe that there was an inherent opposition between observation and reasoning in the methods of discovery, between facts and explanations in the truths of science, and between antecedence and causation in the realities of Nature. In this respect, astronomy has done more for the right adjustment of our conceptions than any190 other branch of knowledge; and it is remarkable that Sextus Empiricus, the last eminent representative of ancient Scepticism, and the only one (unless Cicero is to be called a Sceptic) whose writings are still extant, should expressly except astronomy from the destructive criticism to which he subjects the whole range of studies included in what we should call the university curriculum of his time.301 We need not enter into an analysis of the ponderous compilation referred to; for nearly every point of interest which it comprises has already been touched on in the course of our investigation; and Sextus differs only from his predecessors by adding the arguments of the New Academy to those of Protagoras and Pyrrho, thus completing the Sceptical cycle. It will be enough to notice the singular circumstance that so copious and careful an enumeration of the grounds which it was possible to urge against dogmatism��including, as we have seen, many still employed for the same or other purposes,��should have omitted the two most powerful solvents of any. These were left for the exquisite critical acumen of Hume to discover. They relate to the conception of causation, and to the conception of our own personality as an indivisible, continuously existing substance, being attempts to show that both involve assumptions of an illegitimate character. Sextus comes up to the very verge of Hume��s objection to the former when he observes that causation implies relation, which can only exist in thought;302 but he does not ask how we come to think such a relation, still less does he connect it with the perception of phenomenal antecedence; and his attacks on the various mental faculties assumed by psychologists pass over the fundamental postulate of personal identity, thus leaving Descartes what seemed a safe foundation whereon to rebuild the edifice of metaphysical philosophy."But indeed you were. I called out and you said 'Hush' very quietly. Then I heard the rustle of your dress as you went down the stairs."

FORE:Their pilot needed no instructions. We are still anxious to know whether our perception of a real world comes to us by an exercise of thought, or by a simple impression of sense��whether it is the universal that gives the individual reality, or the individual that shapes itself, by some process not explained, into a universal��whether bodily movements are the causal antecedents of mental functions, or mind rather the reality which gives truth to body��whether the highest life is a life of thought or a life of action��whether intellectual also involves moral progress��whether the state is a mere combination for the preservation of goods and property, or a moral organism developing the idea of right. And about these and such like questions Aristotle has still much to tell us.... His theory of a creative reason, fragmentary as that theory is left, is the answer to all materialistic theories of the universe. To Aristotle, as to a subtle Scottish preacher [Principal Caird] ��the real pre-supposition of all knowledge, or the thought which is the prius of all things, is not the individual��s consciousness of himself as individual, but a thought or self-consciousness which is beyond all individual selves, which is the unity of all individual selves and their objects, of all thinkers and all objects of all thought.��167
