TWO:Sandy did not smile. Instead, as they swung, he scanned the sky. That was not his instructions, but it was his determined plan. TWO:For Sandy��s suspects would certainly incriminate themselves. TWO:"Of course I did. A tiny glass bottle with a tiny glass stopper."When the power and value of these primitive speculations can no longer be denied, their originality is sometimes questioned by the systematic detractors of everything Hellenic. Thales and the rest, we are told, simply borrowed their theories without acknowledgment from a storehouse of Oriental wisdom on which the Greeks are supposed to have drawn as freely as Coleridge drew on German philosophy. Sometimes each system is affiliated to one of the great Asiatic religions; sometimes they are all traced back to the schools of Hindostan. It is natural that no two critics should agree, when the rival explanations are based on nothing stronger than superficial analogies and accidental coincidences. Dr. Zeller in his wonderfully learned, clear, and sagacious work on Greek philosophy, has carefully sifted some of the hypotheses referred to, and shown how destitute they are of internal or external evidence, and how utterly they fail to account for the facts. The oldest and best authorities, Plato and Aristotle, knew nothing about such a derivation of Greek thought from Eastern sources. Isocrates does, indeed, mention that Pythagoras borrowed his philosophy7 from Egypt, but Isocrates did not even pretend to be a truthful narrator. No Greek of the early period except those regularly domiciled in Susa seems to have been acquainted with any language but his own. Few travelled very far into Asia, and of those few, only one or two were philosophers. Democritus, who visited more foreign countries than any man of his time, speaks only of having discussed mathematical problems with the wise men whom he encountered; and even in mathematics he was at least their equal.9 It was precisely at the greatest distance from Asia, in Italy and Sicily, that the systems arose which seem to have most analogy with Asiatic modes of thought. Can we suppose that the traders of those times were in any way qualified to transport the speculations of Confucius and the Vedas to such a distance from their native homes? With far better reason might one expect a German merchant to carry a knowledge of Kant��s philosophy from K?nigsberg to Canton. But a more convincing argument than any is to show that Greek philosophy in its historical evolution exhibits a perfectly natural and spontaneous progress from simpler to more complex forms, and that system grew out of system by a strictly logical process of extension, analysis, and combination. This is what, chiefly under the guidance of Zeller, we shall now attempt to do. TWO:"It is highly deplorable when officers or non-commissioned officers set houses on fire without the permission or order of the commanding, or, as the case may be, the senior officer, or when by their attitude they encourage the rank and file to burn and plunder.I am not aware that any one has defined what constitutes civil engineering, or mechanical engineering, as distinguished one from the other, nor is it assumed to fix any standard here [14] farther than to serve the purpose of explaining the sense in which the terms will be used; yet there seems to be a clear line of distinction, which, if it does not agree with popular use of the terms, at least seems to be furnished by the nature of the business itself. It will therefore be assumed that mechanical engineering relates to dynamic forces and works that involve machine motion, and comprehends the conditions of machine action, such as torsional, centrifugal, intermittent, and irregular strains in machinery, arising out of motion; the endurance of wearing surfaces, the constructive processes of machine-making and machine effect in the conversion of material��in short, agents for converting, transmitting, and applying power.
