      Assuming an air of having forgotten all about Dicks rhyme, he went to his place in the seat behind Jeff and the instant his safety belt was snapped Jeff signaled to a farmer who had come over to investigate and satisfy himself that the airplane had legitimate business there; the farmer kicked the stones used as chocks from under the landing tires and Jeff opened up the throttle.Dick consulted his comrades with his eyes.

      Lucretius has been called Romes only great speculative genius. This is, of course, absurd. A talent for lucid ex101position does not constitute speculative genius, especially when it is unaccompanied by any ability to criticise the opinions expounded. The author of the De Rerum Natura probably had a lawyers education. He certainly exhibits great forensic skill in speaking from his brief. But Cicero and Seneca showed the same skill on a much more extensive scale; and the former in particular was immensely superior to Lucretius in knowledge and argumentative power. Besides, the poet, who was certainly not disposed to hide his light under a bushel, and who exalts his own artistic excellences in no measured terms, never professes to be anything but a humble interpreter of truths first revealed to his Greek instructors vivid intellect. It has, indeed, been claimed for Lucretius that he teaches a higher wisdom than his acknowledged guide.195 This assertion is, however, not borne out by a careful comparison between the two.196 In both there is the same theory of the universe, of man, and of the relations connecting them with one another. The idea of Nature in Lucretius shows no advance over the same idea in Epicurus. To each it expresses, not, as with the Stoics, a unifying power, a design by which all things work together for the best, but simply the conditions of a permanent mechanical aggregation. When Lucretius speaks of foedera Naturai, he means, not what we understand by laws of nature, that is, uniformities of causation underlying all phenomenal differences, to understand which is an exaltation of human dignity through the added power of prevision and control which it bestows, but rather the limiting possibilities of existence, the barriers against which human hopes and aspirations dash themselves in vainan objective logic which guards us against fallacies instead of enabling us to arrive at positive conclusions. We have here the pervadingly negative character of Epicureanism,102 though probably presented with something of Roman solemnity and sternness. The idea of individuality, with which Lucretius has also been credited, occupies but a small place in his exposition, and seems to have interested him only as a particular aspect of the atomic theory. The ultimate particles of matter must be divided into unlike groups of units, for otherwise we could not explain the unlikenesses exhibited by sensible objects. This is neither the original Greek idea, that every man has his own life to lead, irrespective of public opinion or arbitrary convention; nor is it the modern delight in Natures inexhaustible variety as opposed to the poverty of human invention, or to the restrictions of fashionable taste. Nor can we admit that Lucretius developed Epicurean philosophy in the direction of increased attention to the external world. The poet was, no doubt, a consummate observer, and he used his observations with wonderful felicity for the elucidation and enforcement of his philosophical reasoning; but in this respect he has been equalled or surpassed by other poets who either knew nothing of systematic philosophy, or, like Dante, were educated in a system as unlike as possible to that of Epicurus. There is, therefore, every reason for assuming that he saw and described phenomena not by virtue of his scientific training, but by virtue of his artistic endowment. And the same may be said of the other points in which he is credited with improvements on his masters doctrine. There is, no doubt, a strong consciousness of unity, of individuality, and of law running through his poem. But it is under the form of intuitions or contemplations, not under the form of speculative ideas that they are to be found. And, as will be presently shown, it is not as attributes of Nature but as attributes of life that they present themselves to his imagination.

      And that, to Dick, spelled disaster.The Epicurean philosophy of external Nature was used as an instrument for destroying the uncomfortable belief in Divine Providence. The Epicurean philosophy of mind was used to destroy the still more uncomfortable belief in mans immortality. As opinions then stood, the task was a comparatively easy one. In our discussion of Stoicism, we observed that the spiritualism of Plato and Aristotle was far before their age, and was not accepted or even understood by their countrymen for a long time to come. Moreover, Aristotle did not agree with his master in thinking that the personal eternity of the soul followed from its immateriality. The belief of the Stoics in a prolongation of individual existence until the destruction of all created things by fire, was, even in that very limited form, inconsistent with their avowed materialism, and had absolutely no influence on their practical89 convictions. Thus Platos arguments were alone worth considering. For Epicurus, the whole question was virtually settled by the principle, which he held in common with the Stoics, that nothing exists but matter, its attributes, and its relations. He accepted, it is true, the duality of soul and body, agreeing, in this respect also, with the Stoics and the earlier physicists; and the familiar antithesis of flesh and spirit is a survival of his favourite phraseology;173 but this very term flesh was employed to cover the assumption that the body to which he applied it differed not in substance but in composition from its animating principle. The latter, a rather complex aggregate, consists proximately of four distinct elements, imagined, apparently, for the purpose of explaining its various functions, and, in the last analysis, of very fine and mobile atoms.174 When so much had been granted, it naturally followed that the soul was only held together by the body, and was immediately dissolved on being separated from ita conclusion still further strengthened by the manifest dependence of psychic on corporeal activities throughout the period of their joint existence. Thus all terrors arising from the apprehension of future torments were summarily dispelled.

      The steam-engine, in the sense in which the term is employed, means not only steam-using machinery, but steam-generating machinery or plant; it includes the engine proper, with the boiler, mechanism for feeding water to the boiler, machinery for governing speed, indicators, and other details.36


      "No, no, sir," the lady said. "Oh, oh, it is so terrible! By and by the Germans will burn Lige and kill us all. She is the little daughter of my brother at Maastricht, and came to visit us a few days before war broke out, but now she will be killed too, for she refuses to go away."


      A crack-up would not be as bad, perhaps, as a plunge, a dive into the bay!Water may be considered as a rigid medium for transmitting power, corresponding to shafts and gear wheels; air as a flexible or yielding one, corresponding to belts. There is at this time but a limited use of pneumatic apparatus for transmitting power, but its application is rapidly extending, especially in transporting material by means of air currents, and in conveying power to mining machinery.


      Finally, while the attempt to attain extreme accuracy of definition was leading to the destruction of all thought and all reality within the Socratic school, the dialectic method had been taken up and parodied in a very coarse style by a class of persons called Eristics. These men had, to some extent, usurped the place of the elder Sophists as paid instructors of youth; but their only accomplishment was to upset every possible assertion by a series of verbal juggles. One of their favourite paradoxes was to deny the reality of falsehood on the Parmenidean principle that nothing cannot exist. Plato satirises their method in the Euthydmus, and makes a much more serious attempt to meet it in the Sophist; two Dialogues which seem to have been composed not far from one another.156 The Sophist effects a considerable simplification in the ideal theory by resolving negation into difference, and altogether omitting the notions of unity and plurality,perhaps as a result of the investiga265tions contained in the Parmenides, another dialogue belonging to the same group, where the couple referred to are analysed with great minuteness, and are shown to be infected with numerous self-contradictions. The remaining five ideas of Existence, Sameness, Difference, Rest, and Motion, are allowed to stand; but the fact of their inseparable connexion is brought out with great force and clearness. The enquiry is one of considerable interest, including, as it does, the earliest known analysis of predication, and forming an indispensable link in the transition from Platonic to Aristotelian logicthat is to say, from the theory of definition and classification to the theory of syllogism.And that, to Dick, spelled disaster.


      In every case where there can be a question as to whether gearing shafts or belts will be the best means of transmitting power, the several conditions named will furnish a solution if they are properly investigated and understood. Speed, noise, or angles may become determinative conditions, and are such in a large number of cases; first cost and loss of power are generally secondary conditions. Applying these tests to cases where belts, shafts, or wheels may be employed, a learner will soon find himself in possession of knowledge to guide him in his own schemes, and enable him to judge of the correctness of examples that come under his notice.
