ONE:It is evident, then, that Aristotle cannot be approached with the same perfect dispassionateness as the other great thinkers of antiquity. He is, if not a living force, still a force which must be reckoned with in contemporary controversy. His admirers persist in making an authority of him, or at least of quoting him in behalf of their own favourite convictions. We are, therefore, bound to sift his claims with a severity which would not be altogether gracious in a purely historical review. At the same time it is hoped that historical justice will not lose, but gain, by such a procedure. We shall be the better able to understand what Aristotle was, after first showing what he neither was nor could be. And the utility of our investigations will be still further enhanced if we can show that he represents a fixed type regularly recurring in the revolutions of thought.
FORE:In the theory of reasoning the simple proposition is taken as a starting-point; but instead of deducing the syllogism379 from the synthesis of two premises, Aristotle reaches the premises through the conclusion. He tells us, indeed, that reasoning is a way of discovering from what we know, something that we did not know before. With him, however, it is really a process not of discovery but of proof. He starts with the conclusion, analyses it into predicate and subject or major and minor, and then, by a further analysis, introduces a middle term connecting the two. Thus, we begin with the proposition, Caius is mortal, and prove it by interpolating the notion humanity between its two extremes. From this point of view the premises are merely a temporary scaffolding for bringing the major and minor into connexion with the middle term; and this is also the reason why Aristotle recognises three syllogistic figures only, instead of the four admitted by later logicians. For, the middle may either be contained in one extreme and contain the other, which gives us the first figure; or it may contain both, which gives the second figure; or be contained in both, which gives the third; and this is an exhaustive enumeration of the possible combinations.274
FORE:"You couldn't prove it," he said, moodily, "but I can, I must. Prout, I am the sport of either a most amazing piece of misfortune or else the victim of the most cunning and diabolical scheme that man ever dreamed of. I was actually in the corner house within an hour or so of the murder."
FORE:Dick nodded and passed the report to Sandy."Accompany you. Presently, but not quite in the way you imagine. I have made my confession in a way that Mr. Lawrence thoroughly appreciates. It was I who murdered Leon Lalage, my husband, in this house; it was I who palmed those notes off on Dr. Bruce. No reason to tell you why now. And it was I in this very house who robbed my late mistress of her jewels and forged the letter from her husband that caused her to take poison. After that I have no more to say. Gentlemen, I am much obliged by your kind attention, and I say farewell to you, thus."
FORE:We have already seen how this fundamental division is applied to the universe as a whole. But our philosopher is not content with classifying the phenomena as he finds360 them; he attempts to demonstrate the necessity of their dual existence; and in so doing is guilty of something very like a vicious circle. For, after proving from the terrestrial movements that there must be an eternal movement to keep them going, he now assumes the revolving aether, and argues that there must be a motionless solid centre for it to revolve round, although a geometrical axis would have served the purpose equally well. By a still more palpable fallacy, he proceeds to show that a body whose tendency is towards the centre, must, in the nature of things, be opposed by another body whose tendency is towards the circumference. In order to fill up the interval created by this opposition, two intermediate bodies are required, and thus we get the four elementsearth, water, air, and fire. These, again, are resolved into the antithetical couples, dry and wet, hot and cold, the possible combinations of which, by twos, give us the four elements once more. Earth is dry and cold, water cold and wet, air wet and hot, fire hot and dry; each adjacent pair having a quality in common, and each element being characterized by the excess of a particular quality; earth is especially dry, water cold, air wet, and fire hot. The common centre of each antithesis is what Aristotle calls the First Matter, the mere abstract unformed possibility of existence. This matter always combines two qualities, and has the power of oscillating from one quality to another, but it cannot, as a rule, simultaneously exchange both for their opposites. Earth may pass into water, exchanging dry for wet, but not so readily into air, which would necessitate a double exchange at the same moment.Finishing and fitting relates to giving true and accurate dimensions to the parts of machinery that come in contact with each other and are joined together or move upon each other, and consists in cutting away the surplus material which has to be left in founding and forging because of the heated and expanded condition in which the material is treated in these last processes. In finishing, material is operated upon at its normal temperature, in which condition it can be handled, gauged, or measured, and will retain its shape after it is fitted. Finishing comprehends all operations of cutting and abrading, such as turning, boring, planing and grinding, also the handling of material; it is considered the leading department in shop manipulation, because it is the one where the work constructed is organised and brought together. The fitting shop is also that department to which drawings especially apply, and other preparatory operations are usually made subservient to the fitting processes.
