THREE:Of course we are speaking of causation as exercised under the conditions of time, space, matter, and motion. It is then identical with the transmission of energy and obeys the laws of energy. And to talk about causation under any other conditions than these is utter nonsense. But Plotinus and other philosophers exclude the most essential of the conditions specified from their enquiries into the ultimate origin of things. We are expressly informed that the genesis of Nous from the One, and of Soul from Nous, must not be conceived as taking place in time but in eternity.472 Unfortunately those who make such reservations are not consistent. They continue to talk about power, causation, priority, and so forth, as if these conceptions were separable from time. Hence they have to choose between making statements which are absolutely unintelligible and making statements which are absolutely untrue.Engines operated by means of hot air, called caloric engines, and engines operated by gas, or explosive substances, all act substantially upon the same general principles as steam-engines; the greatest distinction being between those engines wherein the generation of heat is by the combustion of fuel, and those wherein heat and expansion are produced by chemical action. With the exception of a limited number of caloric or air engines, steam machinery comprises nearly all expansive engines that are employed at this day for motive-power; and it may be safely assumed that a person who has mastered the general principles of steam-engines will find no trouble in analysing and understanding any machinery acting from expansion due to heat, whether air, gas, or explosive agents be employed.

THREE: His [Aristotle’s] theory of syllogism is simply an explicit statement of the fact that all knowledge, all thought, rests on universal truths or general propositions—that all knowledge, whether ‘deductive’ or ‘inductive,’ is arrived at by the aid, the indispensable aid, of general propositions. We in England have been almost charmed into the belief that reasoning is perpetually from particular to particular, and a ‘village matron’ and her ‘Lucy’ have been used to express the truth for us in the concrete form adapted to our weaker comprehension (Mill’s Logic, bk. ii. ch. 3). We shall next be told, forsooth, that oxygen and hydrogen do not enter into the composition of water, because our village matron ‘perpetually’ drinks it without ‘passing through’ either element, and the analysis of the chemist will be proved as great a fiction as the analysis of the logician. Aristotle has supplied the links which at once upset all such superficial389 analysis. He has shown that even in analogy or example, which apparently proceeds in this way from one particular instance to another particular instance, we are only justified in so proceeding in so far as we have transformed the particular instance into a general proposition.284To estimate how much is yet to be learned in mechanical engineering, we have only to apply the same test, and when we contrast the great variance between the designs of machines and the diversity of their operation, even when applied to similar purposes, their imperfection is at once apparent. It must, however, be considered that if the rules of construction were uniform, and the principles of machine operation as well understood as the strength and arrangement of material in permanent structures, still there would remain the difficulty of adaptation to new [15] processes, which are continually being developed.
