127Hetty gazed at the strange unsigned message with the feeling that she was being made the victim of some foolish joke. But who would play her a silly prank like that? Perhaps Gordon had had something to do with it.
ONE:Various other anecdotes of more or less doubtful authenticity are related, showing that the philosopher could generally, though not always, act up to his own ideal of indifference. He lived with his sister, who was a midwife by profession, and patiently submitted to the household drudgery which she unsparingly imposed on him. Once, however, she succeeded in goading him into a passion; and on being rather inoppor141tunely reminded of his professed principles by a bystander, the sceptic tartly replied that a wretched woman like that was no fit subject for a display of philosophical indifference. On another occasion, when taunted for losing his self-possession at the attack of a furious dog, he observed, with truth, that, after all, philosophers are human beings.228

Lawrence asked, meaningly.

ONE:Lawrence puffed his cigarette in huge enjoyment.The dialectic theory, considered in its relation to physics, tended to substitute the study of uniformity for the study of mechanical causation. But the general conceptions established by science were a kind of soul in Nature; they were immaterial, they could not be perceived by sense, and yet, remaining as they did unchanged in a world of change, they were far truer, far more real, than the phenomena to which they gave unity and definition. Now these self-existent ideas, being subjective in their origin, readily reacted on239 mind, and communicated to it those attributes of fixedness and eternal duration which had in truth been borrowed by them from Nature, not by Nature from them. Plato argued that the soul was in possession of ideas too pure to have been derived from the suggestions of sense, and therefore traceable to the reminiscences of an ante-natal experience. But we can see that the reminiscence was all on the side of the ideas; it was they that betrayed their human origin by the birthmark of abstraction and finalitybetokening the limitation of mans faculties and the interest of his desireswhich still clung to them when from a temporary law of thought they were erected into an everlasting law of things. As Comte would say, Plato was taking out of his conceptions what he had first put into them himself. And, if this consideration applies to all his reasonings on the subject of immortality, it applies especially to what he regards as the most convincing demonstration of any. There is one idea, he tells us, with which the soul is inseparably and essentially associatednamely, the idea of life. Without this, soul can no more be conceived than snow without cold or fire without heat; nor can death approach it without involving a logical contradiction. To assume that the soul is separable from the body, and that life is inseparable from the soul, was certainly an expeditious method of proof. To a modern, it would have the further disadvantage of proving too much. For, by parity of reasoning, every living thing must have an immortal soul, and every soul must have existed from all eternity. Plato frankly accepted both conclusions, and even incorporated them with his ethical system. He looked on the lower animals as so many stages in a progressive degradation to which human beings had descended through their own violence or sensuality, but from which it was possible for them to return after a certain period of penitence and probation. At other times he describes a hell, a purgatory, and a heaven, not unlike what we read of in240 Dante, without apparently being conscious of any inconsistency between the two representations. It was, indeed, an inconsistency such as we find in the highest order of intellects, the inconsistency of one who mediated between two worlds, between naturalistic metempsychosis on the one side, and ethical individualism on the other.

TWO:Hetty was off at once. Balmayne jumped to his feet.
FORE:Thus, while Spinoza draws to a head all the tendencies inherited from Greek philosophy, borrowing from the early physicists their necessarianism; from the Atomists, their exclusion of final causes, their denial of the supernatural, and their infinite worlds; from the Athenian school, their distinction between mind and body and between reason and sense; from Aristotle, his parallelism between causation and syllogism; from the Epicureans, their vindication of pleasure; and from the Stoics, their identification of belief with action, their conquest of passion and their devotion to humanity;it is to the dominant Platonism of the seventeenth century that his system owes its foundation, its development, and its crown; for he begins by realising the abstract conception of being, and infers its absolute infinity from the misleading analogy of space, which is not an abstraction at all; deduces his conclusions according to the geometrical method recommended by Plato; and ends, like Plato, by translating dialectic formulas into the emotional language of religious faith.573
FORE: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.

FORE:"Are you not going to speak first?" Lawrence asked.We have said that the founder of Neo-Platonism contrived to blend the systems of his two great authorities in such a manner as to eliminate much of the relative truth which is contained in each of them taken by itself. It has been reserved for modern thought to accomplish the profounder synthesis which has eliminated their errors in combining their truths. Yet, perhaps, no other system would have satisfied the want of the time so well as that constructed by Plotinus out of the materials at his disposal. Such as it was, that system held its ground as the reigning philosophy until all independent thinking was suppressed by Justinian, somewhat more than two and a half centuries after its authors death. Even then it did not become extinct, but reappeared in Christian literature, in the writings attributed to Dionysius the Areopagite, and again in the daring speculations of Erigena, the father of mediaeval philosophy, to pass under more diluted forms into the teaching of the later Schoolmen, until the time arrived for its renewed study in the original sources as an element of the Platonic revival in the fifteenth century. All this popularity proves, as we say, that Plotinus suited his own age and other ages which reproduced the same general intellectual tendencies. But the important thing was that he made Plato and Aristotle more interesting, and thus led men to study their writings more eagerly than before. The true reign of those philosophers does not begin until we reach the Middle Ages, and the commanding position which they then enjoyed was due, in great measure, to the revolution effected by Plotinus.
TWO:Than rightfully to celebrateWe have seen how Epicurus erected the senses into ultimate arbiters of truth. By so doing, however, he only pushed the old difficulty a step further back. Granting that our perceptions faithfully correspond to certain external images, how can we be sure that these images are themselves copies of a solid and permanent reality? And how are we to determine the validity of general notions representing not some single object but entire classes of objects? The second question may be most conveniently answered first. Epicurus holds that perception is only a finer sort of sensation. General notions are material images of a very delicate texture formed, apparently, on the principle of composition-photographs by the coalescence of many individual images thrown off from objects possessing a greater or less degree of resemblance to one another.186 Thought is produced by the contact of such images with the soul, itself, it will be remembered, a material substance.

TWO:It will be found that information of improvements and mechanical progress that a learner may gather from serial publications can always be exchanged for special knowledge in his intercourse with skilled workmen, who have not the opportunity or means of reading for themselves; and what an apprentice may read and learn in an hour can often be "exchanged" for experimental knowledge that has cost years to acquire.A machine may be mechanically correct, arranged with symmetry, true proportions, and proper movements; but if such a machine has not commercial value, and is not applicable to a useful purpose, it is as much a failure as though it were mechanically inoperative. In fact, this consideration of cost and commercial value must be continually present; and a mechanical education that has not furnished a true understanding of the relations between commercial cost and mechanical excellence will fall short of achieving the objects for which such an education is undertaken. By reasoning from such premises as have been laid down, an apprentice may form true standards by which to judge of plans and processes that he is brought in contact with, and the objects for which they are conducted.

Major and Commanding Officer."We also miss in him their single-minded devotion to philosophy and their rigorous unity of doctrine. The Acragantine sage was a party leader (in which capacity, to his great credit, he victoriously upheld the popular cause), a rhetorician, an engineer, a physician, and a thaumaturgist. The well-known legend relating to his death may be taken as a not undeserved satire on the colossal self-conceit of the man who claimed divine honours during his lifetime. Half-mystic and half-rationalist, he made no attempt to reconcile the two inconsistent sides of his intellectual character. It may be compared to one of those grotesque combinations in which, according to his morphology, the heads and bodies of widely different animals were united during the beginnings of life before they had learned to fall into their proper places. He believed in metempsychosis, and professed to remember the somewhat miscellaneous series of forms through which his own personality had already run. He had been a boy, a girl, a bush, a bird, and a fish. Nevertheless, as we shall presently see, his theory of Nature altogether excluded such a notion as the souls separate existence. We have now to consider what that theory actually was. It will be remembered that Parmenides had affirmed the perpetuity and eternal self-identity of being, but that he had deprived this profound divination of all practical value by interpreting it in a sense which excluded diversity and change. Empedocles also declares creation and destruction to be impossible, but explains that the appearances so denominated arise from the union and separation of four everlasting substancesearth, air, fire, and water. This is the famous doctrine of the four29 elements, which, adopted by Plato and Aristotle, was long regarded as the last word of chemistry, and still survives in popular phraseology. Its author may have been guided by an unconscious reflection on the character of his own philosophical method, for was not he, too, constructing a new system out of the elements supplied by his predecessors? They had successively fixed on water, air, and fire as the primordial form of existence; he added a fourth, earth, and effected a sort of reconciliation by placing them all on an equal footing. Curiously enough, the earlier monistic system had a relative justification which his crude eclecticism lacked. All matter may exist either in a solid, a liquid, or a gaseous form; and all solid matter has reached its present condition after passing through the two other degrees of consistency. That the three modifications should be found coexisting in our own experience is a mere accident of the present rgime, and to enumerate them is to substitute a description for an explanation, the usual fault of eclectic systems. Empedocles, however, besides his happy improvement on Parmenides, made a real contribution to thought when, as Aristotle puts it, he sought for a moving as well as for a material cause; in other words, when he asked not only of what elements the world is composed, but also by what forces were they brought together. He tells us of two such causes, Love and Strife, the one a combining, the other a dissociating power. If for these half-mythological names we read attractive and repulsive forces, the result will not be very different from our own current cosmologies. Such terms, when so used as to assume the existence of occult qualities in matter, driving its parts asunder or drawing them close together, are, in truth, as completely mythological as any figments of Hellenic fancy. Unlike their modern antitypes, the Empedoclean goddesses did not reign together, but succeeded one another in alternate dominion during protracted periods of time. The victory of Love was complete when all things had been drawn into a30 perfect sphere, evidently the absolute Eleatic Being subjected to a Heracleitean law of vicissitude and contradiction. For Strife lays hold on the consolidated orb, and by her disintegrating action gradually reduces it to a formless chaos, till, at the close of another world-period, the work of creation begins again. Yet growth and decay are so inextricably intertwined that Empedocles failed to keep up this ideal separation, and was compelled to admit the simultaneous activity of both powers in our everyday experience, so that Nature turns out to be composed of six elements instead of four, the mind which perceives it being constituted in a precisely similar manner. But Love, although on the whole victorious, can only gradually get the better of her retreating enemy, and Nature, as we know it, is the result of their continued conflict. Empedocles described the process of evolution, as he conceived it, in somewhat minute detail. Two points only are of much interest to us, his alleged anticipation of the Darwinian theory and his psychology. The former, such as it was, has occasionally been attributed to Lucretius, but the Roman poet most probably copied Epicurus, although the very brief summary of that philosophers physical system preserved by Diogenes Laertius contains no allusion to such a topic. We know, however, that in Aristotles time a theory identical with that of Lucretius was held by those who rejected teleological explanations of the world in general and of living organisms in particular. All sorts of animals were produced by spontaneous generation; only those survived which were accidentally furnished with appliances for procuring nourishment and for propagating their kind. The notion itself originated with Empedocles, whose fanciful suppositions have already been mentioned in a different connexion. Most assuredly he did not offer it as a solution of problems which in his time had not yet been mooted, but as an illustration of the confusion which prevailed when Love had only advanced a little way in her ordering, harmonising,31 unifying task. Prantl, writing a few years before the appearance of Mr. Darwins book on the Origin of Species, and therefore without any prejudice on the subject, observes with truth that this theory of Empedocles was deeply rooted in the mythological conceptions of the time.23 Perhaps he was seeking for a rationalistic explanation of the centaurs, minotaurs, hundred-handed giants, and so forth, in whose existence he had not, like Lucretius, learned completely to disbelieve. His strange supposition was afterwards freed from its worst extravagances; but even as stated in the De Rerum Natura, it has no claim whatever to rank as a serious hypothesis. Anything more unlike the Darwinian doctrine, according to which all existing species have been evolved from less highly-organized ancestors by the gradual accumulation of minute differences, it would be difficult to conceive. Every thinker of antiquity, with one exception, believed in the immutability of natural species. They had existed unchanged from all eternity, or had sprung up by spontaneous generation from the earths bosom in their present form. The solitary dissentient was Anaximander, who conjectured that man was descended from an aquatic animal.24 Strange to say, this lucky guess has not yet been quoted as an argument against the Ascidian pedigree. It is chiefly the enemies of Darwinism who are eager to find it anticipated in Empedocles or Lucretius. By a curious inversion of traditionalism, it is fancied that a modern discovery can be upset by showing that somebody said something of the kind more than two thousand years ago. Unfortunately authority has not the negative value of disproving the principles which it supports. We must be content to accept the truths brought to light by observation and reasoning, even at the risk of finding ourselves in humiliating agreement with a philosopher of antiquity.2558Formerly an apprentice entered a shop to learn hand skill, and to acquaint himself with a number of mysterious processes; to learn a series of arbitrary rules which might serve to place him at a disadvantage even with those whose capacity was inferior and who had less education; but now the whole is changed. An engineer apprentice enters the shop with a confidence that he may learn whatever the facilities afford if he will put forth the required efforts; there are no mysteries to be solved; nearly all problems are reached and explained by science, leaving a greater share of the shop-time of a learner to be devoted to studying what is special."It shall be done; I pledge you my word that it shall be done. I have the key to this mystery--I have had it from the first. That is why I persuaded you not to go away again, and not to let anybody know you were in London. But we have by no means done with the corner house yet. We are going to spend an hour or so there this very night."
