TWO:Attention has been called to this case as one wherein the conditions of operation obviously furnish true data to govern the arrangement of machinery, instead of the determinable strains to which the parts are subjected, and as a good example of the importance of studying mechanical conditions from a practical and experimental point of view. If the general diameter of a shaft is based upon the exact amount of power to be transmitted, or if the diameter of a shaft at various parts is based upon the torsional stress that would be sustained at these points, such a shaft would not only fail to meet the conditions of practical use, but would cost more by attempting such an adaptation. The regular working strain to which shafts are subjected is inversely as the speed at which they run. This becomes a strong reason in favour of arranging shafts to run at a maximum speed, provided there was nothing more than first cost to consider; but there are other and more important conditions to be taken into account, principal among which are the required rate of movement where power is taken off to machines, and the endurance of bearings.

TWO:So far, the sceptical theory had been put forward after a somewhat fragmentary fashion, and in strict dependence on the previous development of dogmatic philosophy. With the137 Humanists it had taken the form of an attack on physical science; with the Megarians, of a criticism on the Socratic dialectic; with both, it had been pushed to the length of an absolute negation, logically not more defensible than the affirmations to which it was opposed. What remained was that, after being consistently formulated, its results should be exhibited in their systematic bearing on the practical interests of mankind. The twofold task was accomplished by Pyrrho, whose name has accordingly continued to be associated, even in modern times, with the profession of universal doubt. This remarkable man was a native of Elis, where a branch of the Megarian school had at one time established itself; and it seems likely that the determining impulse of his life was, directly or indirectly, derived from Stilpo��s teaching. A contemporary of Alexander the Great, he accompanied the Macedonian army on its march to India, subsequently returning to his native city, where he died at an advanced age, about 275 B.C. The absurd stories about his indifference to material obstacles when out walking have been already mentioned in a former chapter, and are sufficiently refuted by the circumstances just related. The citizens of Elis are said to have shown their respect for the philosopher by exempting him from taxation, appointing him their chief priest��no inappropriate office for a sceptic of the true type��and honouring his memory with a statue, which was still pointed out to sightseers in the time of Pausanias.226

FORE:��As I live and breathe!�� the man continued, ��I��m seeing things!��The idea of such a provisional code seems to have originated with Zeno;61 but the form under which we now know it is28 the result of at least two successive revisions. The first and most important is due to Panaetius, a Stoic philosopher of the second century B.C., on whose views the study of Plato and Aristotle exercised a considerable influence. A work of this teacher on the Duties of Man furnished Cicero with the materials for his celebrated De Officiis, under which form its lessons have passed into the educational literature of modern Europe. The Latin treatise is written in a somewhat frigid and uninteresting style, whether through the fault of Cicero or of his guide we cannot tell. The principles laid down are excellent, but there is no vital bond of union holding them together. We can hardly imagine that the author��s son, for whom the work was originally designed, or anyone else since his time, felt himself much benefited by its perusal. Taken, however, as a register of the height reached by ordinary educated sentiment under the influence of speculative ideas, and of the limits imposed by it in turn on their vagaries, after four centuries of continual interaction, the De Officiis presents us with very satisfactory results. The old quadripartite division of the virtues is reproduced; but each is treated in a large and liberal spirit, marking an immense advance on Aristotle��s definitions, wherever the two can be compared. Wisdom is identified with the investigation of truth; and there is a caution against believing on insufficient evidence, which advantageously contrasts with what were soon to be the lessons of theology on the same subject. The other great intellectual duty inculcated is to refrain from wasting our energies on difficult and useless enquiries.62 This injunction has been taken up and very impressively repeated by some philosophers in our own time; but in the mouth of Cicero it probably involved much greater restrictions on the study of science than they would be disposed to admit. And the limits now prescribed to speculation by Positivism will perhaps seem not less injudicious,29 when viewed in the light of future discoveries, than those fixed by the ancient moralists seem to us who know what would have been lost had they always been treated with respect.
