THREE:The traction of belts upon pulleys, like that of locomotive wheels upon railways, being incapable of demonstration except by actual experience, for a long time hindered the introduction of belts as a means of transmitting motion and power except in cases when gearing or shafts could not be employed. Motion is named separately, because with many kinds of machinery that are driven at high speedsuch as wood machinesthe transmission of rapid movement must be considered as well as power, and in ordinary practice it is only by means of belts that such high speeds may be communicated from one shaft to another.Evidently this kind of thing had happened before, and this was the fee usually paid. Bruce slipped the money in his pocket, feeling that he had earned it. The guide picked up a Bradshaw from the table and indicated Dover therein. Two strapped portmanteaus were on the floor.
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.
