THREE:Whether there exist any realities beyond what are revealed to us by this evidence, and what sensible evidence itself may be worth, were problems already actively canvassed in Aristotles time. His Metaphysics at once takes us into the thick of the debate. The first question of that age was, What are the causes and principles of things? On one side stood the materialiststhe old Ionian physicists and their living representatives. They said that all things came from water or air or fire, or from a mixture of the four elements, or from the interaction of opposites, such as wet and dry, hot and cold.332 Aristotle, following in the track of his master, Plato, blames them for ignoring the incorporeal substances, by which he does not mean what would now be understoodfeelings or states of consciousness, or even the spiritual substratum of consciousnessbut rather the general qualities or assemblages of qualities which remain constant amid the fluctuations of sensible phenomena; considered, let us observe, not as subjective thoughts, but as objective realities. Another deficiency in the older physical theories is that they either ignore the efficient cause of motion altogether (like Thales), or assign causes not adequate to the purpose (like Empedocles); or when they hit on the true cause do not make the right use of it (like Anaxagoras). Lastly, they have omitted to study the final cause of a thingthe good for which it exists.(1.) In comparing steam-hammers with trip or crank hammers what mechanism does steam supplant or represent?(2.) What can be called the chief distinction between steam and other hammers?(3.) Under what circumstances is an automatic valve motion desirable?(4.) Why is a dead or uncushioned blow most effective?(5.) Will a hammer operate with air the same as with steam?

THREE:The lathe as a tool for producing heliacal forms would occupy a prominent place among machine tools, if it were capable of performing no other work; the number of parts of machinery which have screw-threads is astonishing; clamping-bolts to hold parts together include a large share of the fitting on machinery of all kinds, while screws are the most common means for increasing power, changing movements and performing adjustments.Before parting with Stoicism we have to say a few words on the metaphysical foundation of the whole systemthe theory of Nature considered as a moral guide and support. It has been shown that the ultimate object of this, as of many other ethical theories, both ancient and modern, was to reconcile the instincts of individual self-preservation with virtue, which is the instinct of self-preservation in an entire community. The Stoics identified both impulses by declaring that virtue is the sole good of the individual no less than the supreme interest of the whole; thus involving themselves in an insoluble contradiction. For, from their nominalistic point of view, the good of the whole can be nothing but an aggre45gate of particular goods, or else a means for their attainment; and in either case the happiness of the individual has to be accounted for apart from his duty. And an analysis of the special virtues and vices would equally have forced them back on the assumption, which they persistently repudiated, that individual existence and pleasure are intrinsically good, and their opposites intrinsically evil. To prove their fundamental paradoxthe non-existence of individual as distinguished from social interestthe Stoics employed the analogy of an organised body where the good of the parts unquestionably subserves the good of the whole;100 and the object of their teleology was to show that the universe and, by implication, the human race, were properly to be viewed in that light. The acknowledged adaptation of life to its environment furnished some plausible arguments in support of their thesis; and the deficiencies were made good by a revival of the Heracleitean theory in which the unity of Nature was conceived partly as a necessary interdependence of opposing forces, partly as a perpetual transformation of every substance into every other. Universal history also tended to confirm the same principle in its application to the human race. The Macedonian, and still more the Roman empire, brought the idea of a world-wide community living under the same laws ever nearer to its realisation; the decay of the old religion and the old civic patriotism set free a vast fund of altruism which now took the form of simple philanthropy; while a rank growth of immorality offered ever new opportunities for an indignant protest against senseless luxury and inhuman vice. This last circumstance, however, was not allowed to prejudice the optimism of the system; for the fertile physics of Heracleitus suggested a method by which moral evil could be interpreted as a necessary concomitant of good, a material for the perpetual exercise and illustration of virtuous deeds.101
