TWO:The man laughed silently, horribly, his body twisting as if set on wires. PREFACE
THREE:Before we can come to a decision on this point it will be necessary briefly to recapitulate the statements in question. Socrates is defending himself against a capital charge. He fears that a prejudice respecting him may exist in the minds of the jury, and tries to explain how it arose without any fault of his, as follows:A certain friend of his had asked the oracle at Delphi whether there was any man wiser than Socrates? The answer was that no man was wiser. Not being conscious of possessing any wisdom, great or small, he felt considerably surprised on hearing of this declaration, and thought to convince the god of falsehood by finding out some one wiser than himself. He first went to an eminent politician, who, however, proved, on examination, to be utterly ignorant, with the further disadvantage that it was impossible to convince him of his ignorance. On applying the same test to others a precisely similar result was obtained. It was only the handicraftsmen who could give a satisfactory account of themselves, and their knowledge of one trade made them fancy that they understood everything else equally well. Thus the meaning of the oracle was shown to be that God alone is truly wise, and that of all men he is wisest who, like Socrates, perceives that human wisdom is worth little or nothing. Ever since then, Socrates has made it his business to vindicate the divine veracity by seeking out and exposing every pretender to knowledge that he can find, a line of conduct which has made him extremely unpopular in Athens, while it has also won him a great reputation for wisdom, as people supposed that the matters on which he convicted others of ignorance were perfectly clear to himself.We can try to drop down into the fog, called Larry to Dick as their pilot, with closed throttle, nosed down to get closer to the scene of the tragedy.
THREE: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.In cutting screws it is best not to refer to that mistaken convenience called a wheel list, usually stamped on some part of engine lathes to aid in selecting wheels. A screw to [127] be cut is to the lead screw on a lathe as the wheel on the screw is to the wheel on the spindle, and every workman should be familiar with so simple a matter as computing wheels for screw cutting, when there is but one train of wheels. Wheels for screw cutting may be computed not only quite as soon as read from an index, but the advantage of being familiar with wheel changes is very important in other cases, and frequently such combinations have to be made when there is not an index at hand.
