And so, with the dissolution of our bodily organism, the music of consciousness would pass away for ever. Perhaps no form of psychology taught in the Greek schools has approached nearer to modern thought than this. It was professed at Thebes by two Pythagoreans, Cebes and Simmias, in the time of Plato. He rightly regarded them as formidable opponents, for they were ready to grant whatever he claimed for the soul in the way of immateriality and superiority to the body, while denying the possibility of its separate existence. We may so far anticipate the course of our exposition as to mention that the direct argument by which he met them was a reference to the moving power of mind, and to the constraint exercised by reason over passionate impulse; characteristics which the analogy with a musical harmony failed to explain. But his chief reliance was on an order of considerations, the historical genesis of which we shall now proceed to trace.
12Machinery of transmission being generally a part of the fixed plant of an establishment, experiments cannot be made to institute comparisons, as in the case of machines; besides, there are special or local considerationssuch as noise, danger, freezing, and distanceto be taken into account, which prevent any rules of general application. Yet in every case it may be assumed that some particular plan of transmitting power is better than any other, and that plan can best be determined by studying, first, the principles of different kinds of mechanism and its adaptation to the special conditions that exist; and secondly, precedents or examples.
ONE:"Never mind that, we know too much about one another to say much. I'll open the door whilst you push the motor in. Quiet as the grave."
ONE:From the time of Socrates on, the majority of Greeks, had they been asked what was the ultimate object of endeavour, or what made life worth living, would have answered, pleasure. But among professional philosophers such a definition of the60 supreme good met with little favour. Seeing very clearly that the standard of conduct must be social, and convinced that it must at the same time include the highest good of the individual, they found it impossible to believe that the two could be reconciled by encouraging each citizen in the unrestricted pursuit of his own private gratifications. Nor had such an idea as the greatest happiness of the greatest number ever risen above their horizon; although, from the necessities of life itself, they unconsciously assumed it in all their political discussions. The desire for pleasure was, however, too powerful a motive to be safely disregarded. Accordingly we find Socrates frequently appealing to it when no other argument was likely to be equally efficacious, Plato striving to make the private satisfaction of his citizens coincide with the demands of public duty, and Aristotle maintaining that this coincidence must spontaneously result from the consolidation of moral habits; the true test of a virtuous disposition being, in his opinion, the pleasure which accompanies its exercise. One of the companions of Socrates, Aristippus the Cyrenaean, a man who had cut himself loose from every political and domestic obligation, and who was remarkable for the versatility with which he adapted himself to the most varying circumstances, went still further. He boldly declared that pleasure was the sole end worth seeking, and on the strength of this doctrine came forward as the founder of a new philosophical school. According to his system, the summum bonum was not the total amount of enjoyment secured in a lifetime, but the greatest single enjoyment that could be secured at any moment; and this principle was associated with an idealistic theory of perception, apparently suggested by Protagoras, but carrying his views much further. Our knowledge, said Aristippus, is strictly limited to phenomena; we are conscious of nothing beyond our own feelings; and we have no right to assume the existence of any objects by which they are caused. The study of natural61 science is therefore waste of time; our whole energies should be devoted to the interests of practical life.123 Thus Greek humanism seemed to have found its appropriate sequel in hedonism, which, as an ethical theory, might quote in its favour both the dictates of immediate feeling and the sanction of public opinion.The general theory of their action may be explained in the following propositions:
TWO:Besides this increasing reverence paid to the deified mortals of ancient mythology, the custom of bestowing divine honours on illustrious men after or even before their death, found new scope for its exercise under the empire.232 Among the manifestations of this tendency, the apotheosis of the emperors themselves, of course, ranks first. We are accustomed to think of it as part of the machinery of despotism, surrounded by official ceremonies and enforced by cruel punishments; but, in fact, it first originated in a spontaneous movement of popular feeling; and in the case of Marcus Aurelius at least, it was maintained for a whole century, if not longer, by the mere force of public opinion. And many prophecies (which, as usual, came true) were made on the strength of revelations received from him in dreams.356 But a much stronger proof of the prevalent tendency is furnished by the apotheosis of Antinous. In its origin this may be attributed to the caprice of a voluptuous despot; but its perpetuation long after the motives of flattery or of fear had ceased to act, shows that the worship of a beautiful youth, who was believed to have given his life for another, satisfied a deep-seated craving of the age. It is possible that, in this and other instances, the deified mortal may have passed for the representative or incarnation of some god who was already believed to have led an earthly existence, and might therefore readily revisit the scene of his former activity. Thus Antinous constantly appears with the attributes of Dionysus; and Apollonius of Tyana, the celebrated Pythagorean prophet of the first century, was worshipped at Ephesus in the time of Lactantius under the name of Heracles Alexicacus, that is, Heracles the defender from evil.357
TWO:"All right; you may go!"It is not proposed at this time to treat of the construction of machinery for transmitting power, but to examine into the conditions that should determine which of the several plans of transmitting is best in certain caseswhether belts, gearing, or shafts should be employed, and to note the principles upon which they operate. Existing examples do not furnish data as to the advantages of the different plans for transmitting power, because a given duty may be successfully performed by belts, gearing, or shaftseven by water, air, or steamand the comparative advantages of different means of transmission is not always an easy matter to determine.
TWO:Another principle to be noticed in connection with hammers and forging processes is that of the inertia of the piece operated upona matter of no little importance in the heavier kinds of work.The answer is, surely, not very convincing!
TWO:Plutarch, who was twenty-one when Nero declared his country free, was the first leader in the great Hellenist revival, without, at the same time, entirely belonging to it. He cared more for the matter than for the form of antiquity, for the great deeds and greater thoughts of the past than for the words in which they were related and explained. Hence, by the awkwardness and heaviness of his style, he is more akin to the writers of the Alexandrian period than to his immediate successors. On the one side, he opens the era of classical idealism; on the other, he closes that of encyclopaedic erudition. The next generation bore much the same relation to Plutarch that the first Sophists bore to Hecataeus and Herodotus. Addressing themselves to popular audiences, they were obliged to study perspicuity and elegance of expression, at the risk, it is true, of verbosity and platitude. Such men were Dion Chrysostom, Her?des Atticus, Maximus Tyrius, and Aristeides. But the old models were imitated with more success by writers who lived more entirely in the past. Arrian reproduced the graceful simplicity270 of Xenophon in his narrative of the campaigns of Alexander and his reports of the lectures of Epicttus. Lucian composed dialogues ranking with the greatest masterpieces of lighter Attic literature. The felicity of his style and his complete emancipation from superstition may probably be traced to the same sourcea diligent study of the ancient classics. It is certain that neither as a writer nor as a critic does he represent the average educated taste of his own times. So far from giving polytheism its deathblow, as he was formerly imagined to have done, he only protested unavailingly against its restoration.
THREE:Third. Combination machines can only be employed with success when one attendant performs all the operations, and when the change from one to another requires but little adjustment and re-arrangement.
THREE:"Then I shall shoot."Designing machines must have reference to adaptation, endurance, and the expense of construction. Adaptation includes the performance of machinery, its commercial value, or what the machinery may earn in operating; endurance, the time that machines may operate without being repaired, and the constancy of their performance; expense, the investment represented in machinery.
