× FORE:Hetty promised, wondering."That's a clever question, miss," he said, "but I have a reply to it. We have found a woman near the docks where the unknown stayed for a day or two. As she cannot read or write she got him to write her a line or two to her landlord's agent, sending some arrears of rent and promising the balance shortly. That scrap of paper has come into my possession."

× FORE:The prevailing custom of casting machine frames in one piece, or in as few pieces as possible, leads to a great deal of bar-boring, most of which can be performed accurately enough by boring bars supported in and fed through bearings. By setting up temporary bearings to support boring-bars, and improvising means of driving and feeding, most of the boring on machine frames can be performed on floors or sole plates and independent of boring machines and lathes. There are but few cases in which the importance of studying the principles of tool action is more clearly demonstrated than in this matter of boring; even long practical experience seldom leads to a thorough understanding of the [139] various problems which it involves. 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

× FORE:Descartes had already accomplished a great simplification of the speculative problem by summing up all existence under the two heads of extension and thought. It remained to account for these, and to reduce them to a single idea. As we have seen, they were derived from Greek philosophy, and the bond which was to unite them must be sought for in the same direction. It will be remembered that the systems of Plato and Aristotle were bounded at either extremity by a determinate and by an indeterminate principle. With the one, existence ranged between the Idea of Good at the upper end of the scale and empty space at the lower; with the other, between absolute Thought and First Matter. It was by combining the two definite terms, space and thought, that Descartes had constructed his system; and after subtracting these the two indefinite terms remained. In one respect they were even more opposed to each other than were the terms with which they had been respectively associated. The Idea403 of Good represented unity, identity, and constancy, as against plurality, difference, and change; while Aristotle��s Matter was, by its very definition, multiform, fluctuating, and indeterminate. Nevertheless, there were equally important analogies traceable between them. No very clear account could be given of either, and both were customarily described by negatives. If Matter fell short of complete existence, the Good transcended all existence. If the one was a universal capacity for assuming Forms, the other was the source whence all Forms proceeded. When the distinctive characteristics of an individual were thought away, the question might well be mooted into which principle it would return. The ambiguous use of the word Power contributed still further to their identification, for it was not less applicable to the receptive than to the productive faculty. Now we have just seen into what importance the idea of Power suddenly sprang at the Renaissance: with Bruno it was the only abiding reality of Nature; with Hobbes it was the only object of human desire.It is not proposed at this time to treat of the construction of machinery for transmitting power, but to examine into the conditions that should determine which of the several plans of transmitting is best in certain cases��whether belts, gearing, or shafts should be employed, and to note the principles upon which they operate. Existing examples do not furnish data as to the advantages of the different plans for transmitting power, because a given duty may be successfully performed by belts, gearing, or shafts��even by water, air, or steam��and the comparative advantages of different means of transmission is not always an easy matter to determine.

× FORE:"Why not?"

× FORE:"Yes."��Next you��ll be saying the letter was in a registered envelope from California and was written in Cairo!�� laughed Dick.

× FORE:The Countess came sweeping back again with one tiny phial in her hand. Lawrence did not need to look to see that it was the right one. Unknown to the Countess, he had had it in his possession before."And if I refuse to tell you any story?"

× FORE:The other man nodded. Prout was talking sense now.The quality of castings is governed by a great many things besides what have been named, such as the manner of gating or flowing the metal into the moulds, the temperature and quality of the iron, the temperature and character of the mould��things which any skilled foundryman will take pleasure in explaining in answer to courteous and proper questions.

× FORE:"Is that the woman by any chance?" he asked.

× FORE:What these frenzied orders have cost in human lives History will tell later on.Besides the revival of Platonism, three causes had conspired to overthrow the supremacy of Aristotle. The literary Renaissance with its adoration for beauty of form was alienated by the barbarous dialect of Scholasticism; the mystical theology of Luther saw in it an ally both of ecclesiastical authority and of human reason; and the new spirit of passionate revolt against all tradition attacked the accepted philosophy in common with every other branch of the official university curriculum. Before long, however, a reaction set in. The innovators discredited themselves by an extravagance, an ignorance, a credulity, and an intolerance worse than anything in the teaching which they decried. No sooner was the Reformation organised as a positive doctrine than it fell back for support on the only model of systematic thinking at that time to be found. The Humanists were conciliated by having the original text of Aristotle placed before them; and they readily believed, what was not true, that it contained a wisdom which had eluded mediaeval research. But the great scientific movement of the sixteenth century contributed, more than any other impulse, to bring about an Aristotelian reaction. After winning immortal triumphs in every branch of art and literature, the Italian intellect threw itself with equal vigour into the investigation of physical phenomena. Here Plato could give little help, whereas Aristotle supplied a methodised description of the whole field to be explored, and contributions of extraordinary value towards the under372standing of some, at least, among its infinite details. And we may measure the renewed popularity of his system not only by the fact that Cesalpino, the greatest naturalist of the age, professed himself its adherent, but also by the bitterness of the criticisms directed against it, and the involuntary homage offered by rival systems which were little more than meagre excerpts from the Peripatetic ontology and logic.
