THREE: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.The two elements of error and achievement are so intimately blended and mutually conditioned in the philosophy which we have been reviewing, that to decide on their respective importance is impossible without first deciding on a still larger question��the value of systematic thought as such, and apart from its actual content. For Aristotle was perhaps the greatest master of systematisation that ever lived. The401 framework and language of science are still, to a great extent, what he made them; and it remains to be seen whether they will ever be completely remodelled. Yet even this gift has not been an unmixed benefit, for it was long used in the service of false doctrines, and it still induces critics to read into the Aristotelian forms truths which they do not really contain. Let us conclude by observing that of all the ancients, or even of all thinkers before the eighteenth century, there is none to whom the methods and results of modern science could so easily be explained. While finding that they reversed his own most cherished convictions on every point, he would still be prepared by his logical studies to appreciate the evidence on which they rest, and by his ardent love of truth to accept them without reserve. Most of all would he welcome our astronomy and our biology with wonder and delight, while viewing the development of modern machinery with much more qualified admiration, and the progress of democracy perhaps with suspicious fear. He who thought that the mind and body of an artisan were alike debased by the exercise of some simple handicraft under the pure bright sky of Greece, what would he have said to the effect wrought on human beings by the noisome, grinding, sunless, soulless drudgery of our factories and mines! How profoundly unfitted would he have deemed its victims to influence those political issues with which the interests of science are every day becoming more vitally connected! Yet slowly, perhaps, and unwillingly, he might be brought to perceive that our industry has been the indispensable basis of our knowledge, as supplying both the material means and the moral ends of its cultivation. He might also learn that there is an even closer relationship between the two: that while the supporters of privilege are leagued for the maintenance of superstition, the workers, and those who advocate their claims to political equality, are leagued for its restraint and overthrow. And if402 he still shrank back from the heat and smoke and turmoil amid which the genius of our age stands, like another Heracleitus, in feverish excitement, by the steam-furnace whence its powers of revolutionary transmutation are derived, we too might reapply the words of the old Ephesian prophet, bidding him enter boldly, for here also there are gods.

THREE:But all this time the popular belief in omens had continued unaffected, and had apparently even increased. The peculiar Greek feeling known as Deisidaimonia is first satirised by Theophrastus, who defines it as cowardice with regard to the gods, and gives several amusing instances of the anxiety occasioned by its presence��all connected with the interpretation of omens��such as Aristophanes could hardly have failed to notice had they been usual in his time. Nor were such fancies confined to the ignorant classes. Although the Stoics cannot be accused of Deisidaimonia, they gave their powerful sanction to the belief in divination, as has been already mentioned in our account of their philosophy. It223 would seem that whatever authority the great oracular centres had lost was simply handed over to lower and more popular forms of the same superstition.
