Nevertheless, after all has been said, we are conscious of a great change in passing from the Greek moralist to the Roman poet. We seem to be breathing a new atmosphere, to find the old ideas informed with an unwonted life, to feel ourselves in the presence of one who has a power of stamping his convictions on us not ordinarily possessed by the mere imitative disciple. The explanation of this difference, we think, lies in the fact that Lucretius has so manipulated the Epicurean doctrines as to convert them from a system into a picture; and that he has saturated this picture with an emotional tone entirely wanting to the spirit of Epicureanism as it was originally designed. It is with the latter element that we may most conveniently begin.I am well aware of the popular opinion that such subjects are too abstruse to be understood by practical mechanicsan assumption that is founded mainly in the fact that the subject of heat and motion are not generally studied, and have been too recently demonstrated in a scientific way to command confidence and attention; but the subject is really no more difficult to understand in an elementary sense than that of the relation between movement and force illustrated in the "mechanical powers" of school-books, which no apprentice ever did or ever will understand, except by first studying the principles of force and motion, independent of mechanical agents, such as screws, levers, wedges, and so on.
ONE:We have now to study an analogous, though far less complicated, antagonism in ancient Greece, and to show how her most brilliant period of physical philosophy arose from the combination of two seemingly irreconcilable systems. Parmenides, in an address supposed to be delivered by Wisdom to her disciple, warns us against the method pursued by ignorant mortals, the blind, deaf, stupid, confused tribes, who hold that to be and not to be are the same, and that all things move round by an inverted path.19 What Parmenides denounced as arrant nonsense was deliberately proclaimed to be the highest truth by his illustrious contemporary, Heracleitus, of Ephesus. This wonderful thinker is popularly known as the weeping philosopher, because, according to a very silly tradition, he never went abroad without shedding tears over the follies of mankind. No such mawkish sentimentality, but bitter scorn and indignation, marked the attitude of23 Heracleitus towards his fellows. A self-taught sage, he had no respect for the accredited instructors of Hellas. Much learning, he says, does not teach reason, else it would have taught Hesiod and Pythagoras, Xenophanes and Hecataeus.20 Homer, he declares, ought to be flogged out of the public assemblages, and Archilochus likewise. When the highest reputations met with so little mercy, it will readily be imagined what contempt he poured on the vulgar herd. The feelings of a high-born aristocrat combine with those of a lofty genius to point and wing his words. The many are bad and few are the good. The best choose one thing instead of all, a perpetual well-spring of fame, while the many glut their appetites like beasts. One man is equal to ten thousand if he is the best. This contempt was still further intensified by the very excusable incapacity of the public to understand profound thought conveyed in a style proverbial for its obscurity. Men cannot comprehend the eternal law; when I have explained the order of Nature they are no wiser than before. What, then, was this eternal law, a knowledge of which Heracleitus found so difficult to popularise? Let us look back for a moment at the earlier Ionian systems. They had taught that the universe arose either by differentiation or by condensation and expansion from a single primordial substance, into which, as Anaximander, at least, held, everything, at last returned. Now, Heracleitus taught that this transformation is a universal, never-ending, never-resting process; that all things are moving; that Nature is like a stream in which no man can bathe twice; that rest and stability are the law, not of life, but of death. Again, the Pythagorean school, as we have seen, divided all things into a series of sharply distinguished antithetical pairs. Heracleitus either directly identified the terms of every opposition, or regarded them as necessarily combined, or as continually24 passing into one another. Perhaps we shall express his meaning most thoroughly by saying that he would have looked on all three propositions as equivalent statements of a single fact. In accordance with this principle he calls war the father and king and lord of all, and denounces Homers prayer for the abolition of strife as an unconscious blasphemy against the universe itself. Yet, even his powerful intellect could not grasp the conception of a shifting relativity as the law and life of things without embodying it in a particular material substratum. Following the Ionian tradition, he sought for a world-element, and found it in that cosmic fire which enveloped the terrestrial atmosphere, and of which the heavenly luminaries were supposed to be formed. Fire, says the Ephesian philosopher, no doubt adapting his language to the comprehension of a great commercial community, is the general medium of exchange, as gold is given for everything, and everything for gold. The world was not created by any god or any man, but always was, and is, and shall be, an ever-living fire, periodically kindled and quenched25. By cooling and condensation, water is formed from fire, and earth from water; then, by a converse process called the way up as the other was the way down, earth again passes into water and water into fire. At the end of certain stated periods the whole world is to be reconverted into fire, but only to enter on a new cycle in the series of its endless revolutionsa conception, so far, remarkably confirmed by modern science. The whole theory, including a future world conflagration, was afterwards adopted by the Stoics, and probably exercised a considerable influence on the eschatology of the early Christian Church. Imagination is obliged to work under forms which thought has already superseded; and Heracleitus as a philosopher had forestalled the dazzling consummation to which as a prophet he might look forward in wonder and hope. For, his elemental fire was only a picturesque presentation indispensable to him, but not to us, of the sovereign law wherein all things live and move and have their being. To have introduced such an idea into speculation was his distinctive and inestimable achievement, although it may have been suggested by the ε?μαρμ?νη or destiny of the theological poets, a term occasionally employed in his writings. It had a moral as well as a physical meaning, or rather it hovers ambiguously between the two. The sun shall not transgress his bounds, or the Erinyes who help justice will find him out. It is the source of human laws, the common reason which binds men together, therefore they should hold by it even more firmly than by the laws of the State. It is not only all-wise but all-good, even where it seems to be the reverse; for our distinctions between good and evil, just and unjust, vanish in the divine harmony of Nature, the concurrent energies and identifying transformations of her universal life.

  • FORE:Strains suggest special arrangement, which is quite a distinct matter from general arrangement, the latter being governed mainly by the convenience of manipulation. Special arrangement deals with and determines the shape of framing, following the strains throughout a machine. In the present case we have a cutting strain which may be assumed as equal to one ton, exerted between the bracket or jaws which support the work, and the crank-shaft. It follows that between these two points the metal in the framing should be disposed in as direct a line as possible, and provision be made to resist flexion by deep sections parallel with the cutting motion.Charlton gripped Lawrence's arm with convulsive force.

The whole intricacy of the process lies in its application or economic value, and but very few, even among the most skilled, are able in all cases to decide when milling can be employed to advantage. Theoretical conclusions, aside from practical experience, will lead one to suppose that milling can be applied in nearly all kinds of work, an opinion [143] which has in many cases led to serious mistakes.

THREE:It remains to add a few words on the position which ancient and modern philosophy respectively occupy towards theology. Here their relation is one of contrast rather than of resemblance. The Greek thinkers start at an immense distance from religious belief, and their first allusions to it are marked by a scornful denial of its validity. Gradually, with the transition from physical to ethical enquiries, an approximation between the two is brought about, though not without occasional returns to their former attitude of hostility. Finally, in presence of a common danger they become interwoven and almost identified with one another; while the new religion against which they make common cause, itself presents the same spectacle of metaphysical and moral ideas entering into combination with the spontaneous products of popular mythology. And be it observed that throughout the whole of this process action and reaction were equal and contrary. The decline and corruption of philosophy was the price paid for the elevation and purification of religion. While the one was constantly sinking, the other was constantly rising, until they converged on the plane of dogmatic theology. By the very circumstances of the case, an opposite course has been imposed on the development of modern philosophy. Starting from an intimate union with religion, it slowly disengages itself from the compromising alliance; and, although, here also, the normal course of ideas has been interrupted by frequent reactions, the general movement of European thought has been no less decidedly towards a complete emancipation from the popular beliefs than the movement of Greek thought had been towards their conciliation and support.To follow the same chain of reasoning still farther, and to show what may be gained by method and system in learning mechanics, it may be assumed that machine functions consist in the application of power, and therefore power should be first studied; of this there can be but one opinion. The learner who sets out to master even the elementary principles of mechanics without first having formed a true conception of power as an element, is in a measure wasting his time and squandering his efforts.

In the case of iron manufacture, for example, it would cost ten times as much to transport the ore and the fuel used in smelting as it does to transport the manufactured iron; steam-power saves this difference, and without such power our present iron traffic would be impossible. In a great many manufacturing processes steam is required for heating, bleaching, boiling, and so on; besides, steam is now to a large extent employed for warming buildings, so that even when water or other power is employed, in most cases steam-generating apparatus has to be set up in addition. In many cases waste [31] steam or waste heat from a steam-engine can be employed for the purposes named, saving most of the expense that must be incurred if special apparatus is employed.
