THREE:It has been the fashion in certain quarters to look down on these early thinkersto depreciate the value of their speculations because they were thinkers, because, as we have already noticed, they reached their most important conclusions by thinking, the means of truly scientific observation not being within their reach. Nevertheless, they performed services to humanity comparable for value with the legislation of Solon and Cleisthenes, or the victories of Marathon and Salamis; while their creative imagination was not inferior to that of the great lyric and dramatic poets, the great architects and sculptors, whose contemporaries they were. They first taught men to distinguish between the realities of nature and the illusions of sense; they discovered or divined the indestructibility of matter and its atomic constitution; they taught that space is infinite, a conception so far from being self-evident that it transcended the capacity of Aristotle to grasp; they held that the seemingly eternal universe was brought into its present form by the operation of mechanical forces which will also effect its dissolution; confronted by the seeming permanence and solidity of our planet, with the innumerable varieties of life to be found on its surface, they declared that all things had arisen by differentiation8 from a homogeneous attenuated vapour; while one of them went so far as to surmise that man is descended from an aquatic animal. But higher still than these fragmentary glimpses and anticipations of a theory which still awaits confirmation from experience, we must place their central doctrine, that the universe is a cosmos, an ordered whole governed by number and law, not a blind conflict of semi-conscious agents, or a theatre for the arbitrary interference of partial, jealous,6 and vindictive gods; that its changes are determined, if at all, by an immanent unchanging reason; and that those celestial luminaries which had drawn to themselves in every age the unquestioning worship of all mankind were, in truth, nothing more than fiery masses of inanimate matter. Thus, even if the early Greek thinkers were not scientific, they first made science possible by substituting for a theory of the universe which is its direct negation, one that methodised observation has increasingly tended to confirm. The garland of poetic praise woven by Lucretius for his adored master should have been dedicated to them, and to them alone. His noble enthusiasm was really inspired by their lessons, not by the wearisome trifling of a moralist who knew little and cared less about those studies in which the whole soul of his Roman disciple was absorbed.
FORE:The arrangement of patterns with reference to having certain parts of castings solid and clean is an important matter, yet one that is comparatively easy to understand. Supposing the iron in a mould to be in a melted state, and to contain, as it always must, loose sand and 'scruff,' and that the weight of the dirt is to melted iron as the weight of cork is to water, it is easy to see where this dirt would lodge, and where it would be found in the castings. The top of a mould or cope, as it is called, contains the dirt, while the bottom or drag side is generally clean and sound: the rule is to arrange patterns so that the surfaces to be finished will come on the bottom or drag side.

FORE:Once more, there was a cause of intellectual degeneration at work in the ancient world, which for us has almost ceased to exist. This was the flood of barbarism which enveloped and corrupted, long before it overwhelmed, the Hellenised civilisation of Rome. But if the danger of such an inundation is for ever removed, are we equally secure against the contagion of that intellectual miasma which broods over the multitudinous barbarian populations among whom we in turn are settling as conquerors and colonists? Anyone choosing to264 maintain the negative might point to the example of a famous naturalist who, besides contributing largely to the advancement of his own special science, is also distinguished for high general culture, but whom long residence in the East Indies has fitted to be the dupe of impostures which it is a disgrace even for men and women of fashion to accept. Experience, however, teaches us that, so far at least, there is little danger to be dreaded from this quarter. Instead of being prone to superstition, Anglo-Indian society is described as prevailingly sceptical or even agnostic; and, in fact, the study of theology in its lowest forms is apt to start a train of reflection not entirely conducive to veneration for its more modern developments. For the rest, European enlightenment seems likely to spread faster and farther among the conquered, than Oriental darkness among the conquering race.
