FORE:For manufacturing processes, one importance of steam-power rests in the fact that such power can be taken to the material; and beside other advantages gained thereby, is the difference in the expense of transporting manufactured products and the raw material. 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.

FORE:Two precepts stand out before all others, which, trivial as they may seem, are uttered from the very soul of Greek62 experience, Be moderate, and, Know thyself. Their joint observance constitutes the characteristic virtue of S?phrosyn, which means all that we understand by temperance, and a great deal more besides; so much, in fact, that very clever Greeks were hard set to define it, and very wise Greeks could pray for it as the fairest gift of the gods.48 Let us suppose that each individual has a sphere of activity marked out for him by his own nature and his special environment; then to discern clearly the limits of that sphere and to keep within them would be S?phrosyn, while the discernment, taken alone, would be wisdom. The same self-restraint operating as a check on interference with other spheres would be justice; while the expansive force by which a man fills up his entire sphere and guards it against aggressions may be called courage. Thus we are enabled to comprehend the many-sided significance of S?phrosyn, to see how it could stand both for a particular virtue and for all virtuousness whatever. We need only glance at Homers poems, and in particular at the Iliada much deeper as well as a more brilliant work than the Odysseyto perceive how very early this demand for moderation combined with self-knowledge had embodied itself in Greek thought. Agamemnon violates the rights of Achilles under the influence of immoderate passion, and through ignorance of how little we can accomplish without the heros assistance. Achilles, again, carries his vindictiveness too far, and suffers in consequence. But his self-knowledge is absolutely perfect; conscious that he is first in the field while others are better in council, he never undertakes a task to which his powers are not fully adequate; nor does he enter on his final work of vengeance without a clear consciousness of the speedy death which its completion will entail on himself. Hector, too, notwithstanding ominous forebodings, knows his duty and does it, but with much less just an estimate of his own powers, leading him to pursue his success too far, and then, when the63 tide has turned, not permitting him to make a timely retreat within the walls of Troy. So with the secondary characters. Patroclus also oversteps the limits of moderation, and pays the penalty with his life. Diomed silently bears the unmerited rebuke of Agamemnon, but afterwards recalls it at a most effective moment, when rising to oppose the craven counsels of the great king. This the Greeks called observing opportunity, and opportunism was with them, as with French politicians, a form of moderation.49 Down at the very bottom of the scale Thersites and Dolon are signal examples of men who do not know their sphere and suffer for their folly. In the Odyssey, Odysseus is a nearly perfect type of wisdom joined with self-control, erring, if we remember rightly, only once, when he insults Polyphemus before the ship is out of danger; while his comrades perish from want of these same gifts.Epicurus was born 341 B.C., about the same time as Zeno the Stoic. Unlike all the other philosophers of his age, he was of Athenian parentage; that is to say, he belonged to a race of exclusively practical tendencies, and marked by a singular inaptitude or distaste for physical enquiries. His father, a poor colonist in Samos, was, apparently, not able to give him a very regular education. At eighteen he was sent to Athens, but was shortly afterwards obliged to rejoin his family, who were driven from Samos in 322, along with the other Athenian settlers, by a political revolution, and had taken refuge in Colophon, on the Asiatic coast. In the course of his wanderings, the future philosopher came across some public lecturers, who seem to have instructed him in the physics of Democritus, and perhaps also in the scepticism of Pyrrho; but of such a steady discipline as Plato passed through during his ten years intercourse with Socrates, Aristotle during his twenty years studies under Plato, and Zeno during his similarly protracted attendance at the various schools of Athens, there is no trace whatever. Epicurus always described himself as self-taught, meaning that his knowledge had been acquired by reading instead of by listening; and we find in him the advantages as well as the defects common to self-taught men in all agesconsiderable freshness and freedom from scholastic prejudices, along with a59 certain narrowness of sympathies, incompleteness of information, inaptitude for abstract reasoning, and last, but not least, an enormous opinion of his own abilities, joined to an overweening contempt for those with whose opinions he did not agree. After teaching for some time in Mityln, Epicurus established himself as the head of a school in Athens, where he bought a house and garden. In the latter he lectured and gathered round him a band of devoted friends, among whom women were included, and who were wont to assemble for purposes of social recreation not less than of philosophic discipline. Just before his death, which occurred in the year 270, he declared in a letter to his friend and destined successor Hermarchus, that the recollection of his philosophical achievements had been such a source of pleasure as to overcome the agonies of disease, and to make the last day the happiest of his life.121 For the rest, Epicurus secluded himself, on principle, from the world, and few echoes of his teaching seem to have passed beyond the circle of his immediate adherents. Thus, whatever opportunities might otherwise have offered themselves of profiting by adverse criticism were completely lost.122
