Returning to our more immediate subject, we must observe that the Pythagoreans did not maintain, in anticipation of modern quantitative science, that all things are determined by number, but that all things are numbers, or are made out of numbers, two propositions not easily distinguished by unpractised thinkers. Numbers, in a word, were to them precisely what water had been to Thales, what air was to Anaximenes, the absolute principle of existence; only with them the idea of a limit, the leading inspiration of Greek thought, had reached a higher degree of abstraction. Number was, as it were, the exterior limit of the finite, and the interior limit of the infinite. Add to this that mathematical studies, cultivated in Egypt and Phoenicia for their practical utility alone, were being pursued in Hellas with ever-increasing ardour for the sake of their own delightfulness, for the intellectual discipline that they supplieda discipline even12 more valuable then than now, and for the insight which they bestowed, or were believed to bestow, into the secret constitution of Nature; and that the more complicated arithmetical operations were habitually conducted with the aid of geometrical diagrams, thus suggesting the possibility of applying a similar treatment to every order of relations. Consider the lively emotions excited among an intelligent people at a time when multiplication and division, squaring and cubing, the rule of three, the construction and equivalence of figures, with all their manifold applications to industry, commerce, fine art, and tactics, were just as strange and wonderful as electrical phenomena are to us; consider also the magical influence still commonly attributed to particular numbers, and the intense eagerness to obtain exact numerical statements, even when they are of no practical value, exhibited by all who are thrown back on primitive ways of living, as, for example, in Alpine travelling, or on board an Atlantic steamer, and we shall cease to wonder that a mere form of thought, a lifeless abstraction, should once have been regarded as the solution of every problem, the cause of all existence; or that these speculations were more than once revived in after ages, and perished only with Greek philosophy itself.

Their very religion, though burdened with an enormous mass of fictitious legends, shows a certain unwillingness to transgress the more obvious laws of nature, not noticeable in the traditions of kindred or neighbouring races. Its tendency is rather to imagine supernatural causes for natural events, or to read a divine meaning into accidental occurrences, than to introduce impossibilities into the ordinary course of history. And some of its most marvellous stories are told in such a manner that the incredulous satire with which they were originally received is, by a beautiful play of irony, worked into the very texture of the narrative itself. For example, the Greeks were especially disinclined to believe that one of the lower animals could speak with a human voice, or that a dead man could be brought back to lifecontradicted as both suppositions were by the facts of universal experience. So when the horse Xanthus replies to his masters reproaches, Homer adds that his voice was arrested by the Erinyesthat is to say, by the laws of nature; and we may suspect that nothing more is intended by his speech than the interpretation which Achilles would spontaneously put on the mute and pathetic gaze of the faithful steed. And when, to illustrate the wondrous medical skill of Asclpius, it is related that at last he succeeded in restoring a dead man to life, the story adds that for this impious deed both the healer and his patient were immediately transfixed by a thunderbolt from heaven.215 Another impossibility is to predict with any certainty the future fate of individuals, and here alsoas has been already observed in a different connexion216the Greeks showed their extreme scepticism with regard to any alleged contravention of a natural law, under the transparent disguise of stories about persons whom ambiguous predictions had lured to their fall.このページの先頭です
ONE:We have already repeatedly alluded to the only man of genius whom Epicureanism ever counted among its disciples. It is time that we should determine with more precision the actual relation in which he stood to the master whom, with a touching survival of religious sentiment, he revered as a saviour and a god.

"Charlton's white set face as he pressed against the panes."--Page 124But patience is generally rewarded. Here was a hiatus after a series of regular dates. The writer had been drinking heavily, somebody had got hold of him, and was detaining him somewhere against his will. He was not allowed to say where he was. His last letter of the series hinted at a possibility of large sums of money.As a means for transmitting power, shafts afford the very important advantage that power can be easily taken off at any point throughout their length, by means of pulleys or gearing, also in forming a positive connection between the motive-power and machines, or between the different parts of machines. The capacity of shafts in resisting torsional strain is as [46] the cube of their diameter, and the amount of torsional deflection in shafts is as their length. The torsional capacity being based upon the diameter, often leads to the construction of what may be termed diminishing shafts, lines in which the diameter of the several sections are diminished as the distance from the driving power increases, and as the duty to be performed becomes less. This plan of arranging line shafting has been and is yet quite common, but certainly was never arrived at by careful observation. Almost every plan of construction has both advantages and disadvantages, and the best means of determining the excess of either, in any case, is to first arrive at all the conditions as near as possible, then form a "trial balance," putting the advantages on one side and the disadvantages on the other, and footing up the sums for comparison. Dealing with this matter of shafts of uniform diameter and shafts of varying diameter in this way, there may be found in favour of the latter plan a little saving of material and a slight reduction of friction as advantages. The saving of material relates only to first cost, because the expense of fitting is greater in constructing shafts when the diameters of the different pieces vary; the friction, considering that the same velocity throughout must be assumed, is scarcely worth estimating.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 authors 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 Aristotles 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.
