All these, however, are mere questions of detail. It is on a subject of the profoundest philosophical importance that Aristotle differs most consciously, most radically, and most fatally from his predecessors. They were evolutionists, and he was a stationarist. They were mechanicists, and he was a teleologist. They were uniformitarians, and he was a dualist. It is true that, as we mentioned at the beginning of this chapter, Mr. Edwin Wallace makes him recognise the genesis of things by evolution and development, but the meaning of this phrase requires to be cleared up. In one sense it is, of course, almost an identical proposition. The genesis of things must be by genesis of some kind or other. The great question is, what things have been evolved, and how have they been evolved? Modern science tells us, that not only have all particular aggregates of matter and motion now existing come into being within a finite period of time, but also that the specific types under which we arrange those aggregates have equally been generated; and that their characteristics, whether structural or functional, can only be understood by tracing out their origin and history. And it further teaches us that the properties of every aggregate result from the properties of its ultimate elements, which, within the limits of our experience, remain absolutely unchanged. Now, Aristotle taught very nearly the contrary of all this. He believed that the cosmos, as we now know it, had existed, and would continue to exist, unchanged through all eternity. The sun, moon, planets, and stars, together with the orbs containing them, are composed of an absolutely ungenerable, incorruptible substance. The earth, a cold, heavy, solid sphere, though liable to superficial changes, has always occupied its present position in the centre of the universe.317 The specific forms of animal lifeexcept a few which are produced spontaneouslyhave, in like manner, been preserved unaltered through an infinite series of generations. Man shares the common lot. There is no continuous progress of civilisation. Every invention and discovery has been made and lost an infinite number of times. Our philosopher could not, of course, deny that individual living things come into existence and gradually grow to maturity; but he insists that their formation is teleologically determined by the parental type which they are striving to realise. He asks whether we should study a thing by examining how it grows, or by examining its completed form: and Mr. Wallace quotes the question without quoting the answer.203 Aristotle tells us that the genetic method was followed by his predecessors, but that the other method is his. And he goes on to censure Empedocles for saying that many things in the animal body are due simply to mechanical causation; for example, the segmented structure of the backbone, which that philosopher attributes to continued doubling and twistingthe very same explanation, we believe, that would be given of it by a modern evolutionist.204 Finally, Aristotle assumes the only sort of transformation which we deny, and which Democritus equally deniedthat is to say, the transformation of the ultimate elements into one another by the oscillation of an indeterminate matter between opposite qualities.By examining into the facts, an apprentice will find that all truly successful establishments have been founded and built upon the mechanical abilities of some person or persons whose skill formed a base upon which the business was reared, and that true skill is the element which must in the end lead to permanent success. The material and the labour which make up the first cost of machines are, taking an average of various classes, nearly equally divided; labour being in excess for the finer class of machinery, and the material in excess for the coarser kinds of work. The material is presumed to be purchased at the same rates by those of inferior skill as by those that are well skilled, so that the difference in the first, or manufacturing cost of machinery, is determined mainly by skill.
ONE:Where the Cynics left off the Stoics began. Recognising simple self-preservation as the earliest interest and duty of man, they held that his ultimate and highest good was complete self-realisation, the development of that rational, social, and beneficent nature which distinguishes him from the lower21 animals.49 Here their teleological religion came in as a valuable sanction for their ethics. Epicttus, probably following older authorities, argues that self-love has purposely been made identical with sociability. The nature of an animal is to do all things for its own sake. Accordingly God has so ordered the nature of the rational animal that it cannot obtain any particular good without at the same time contributing to the common good. Because it is self-seeking it is not therefore unsocial.50 But if our happiness depends on external goods, then we shall begin to fight with one another for their possession:51 friends, father, country, the gods themselves, everything will, with good reason, be sacrificed to their attainment. And, regarding this as a self-evident absurdity, Epicttus concludes that our happiness must consist solely in a righteous will, which we know to have been the doctrine of his whole school.
TWO:In spiral gearing the line of force is at an angle of forty-five degrees with the bearing faces of the teeth, and the sliding movement equal to the speed of the wheels at their periphery; the bearing on the teeth, as before said, is one of line contact only. Such wheels cannot be employed except in cases where an inconsiderable force is to be transmitted. Spiral wheels are employed to connect shafts that cross each other at right angles but in different planes, and when the wheels can be of the same size.
TWO:A somewhat similar observation applies to the art of reasoning, which it would be possible to compile by bringing together all the rules on the subject, scattered through the Organon. Aristotle has discovered and formulated every canon of theoretical consistency, and every artifice of dialectical debate, with an industry and acuteness which cannot be too highly extolled; and his labours in this direction have perhaps contributed more than those of any other single writer to the intellectual stimulation of after ages; but the kind of genius requisite for such a task was speculative rather than practical; there was no experience of human nature in its concrete manifestations, no prevision of real consequences involved. Such a code might be, and probably was to a great extent, abstracted from the Platonic dialogues; but to work up the processes of thought into a series of dramatic contests, carried on between living individuals, as Plato has done, required a vivid perception and grasp of realities which, and not any poetical mysticism, is what positively distinguishes a Platonist from an Aristotelian.190
THREE:The discovery turned her sick and faint. That any one should deliberately try and take an innocent life like this filled her with loathing.Hetty had nothing to say. She was tired and worn out, and the cool contempt of her employer was galling. The Countess came into her bedroom presently; all her coldness had gone. She was the winning, gracious woman now as the world knew her. She had a little medicine glass in her hand.
