The next step was to create a method for determining the particular configuration on which any given property of matter depends. If such a problem could be solved at all, it would be by some new system of practical analysis. Bacon did not see this because he was a Schoolman, emancipated, indeed,377 from ecclesiastical authority, but retaining a blind faith in the power of logic. Aristotles Organon had been the great storehouse of aids to verbal disputation; it should now be turned into an instrument for the more successful prosecution of physical researches. What definitions were to the one, that Forms should be to the other; and both were to be determined by much the same process. Now Aristotle himself had emphatically declared that the concepts out of which propositions are constructed were discoverable by induction and by induction alone. With him, induction meant comparing a number of instances, and abstracting the one circumstance, if any, in which they agreed. When the object is to establish a proposition inductively, he has recourse to a method of elimination, and bids us search for instances which, differing in everything else, agree in the association of two particular marks.541 In the Topics he goes still further and supplies us with a variety of tests for ascertaining the relation between a given predicate and a given subject. Among these, Mills Methods of Difference, Residues, and Concomitant Variations are very clearly stated.542 But he does not call such modes of reasoning Induction. So far as he has any general name for them at all, it is Dialectic, that is, Syllogism of which the premises are not absolutely certain; and, as a matter of nomenclature, he seems to be right. There is, undoubtedly, a process by which we arrive at general conclusions from the comparison of particular instances; but this process in its purity is nothing more nor less than induction by simple enumeration. All other reasoning requires the aid of universal propositions, and is therefore, to that extent, deductive. The methods of elimination or, as they are now called, of experiment, involve at every step the assumption of378 general principles duly specified in the chapter of Mills Logic where they are analysed. And wherever we can rise immediately from, a single instance to a general law, it is because the examination of that single instance has been preceded by a chain of deductive reasoning."Here's a discovery," he said, excitedly. "Here's a perfect revelation. Mr. Charlton, will you trust me for four and twenty hours with this letter? I've found out something that fairly takes my breath away."
FORE:Even if Jeff did want to catch us and demand ransom to let us go, he remarked quietly, he wasnt outside that rolling doorand I dont think he could pull it down anyhow.
"It was in the interests of our suffering country, and we are those who ought to be grateful. May I insist once more that you ask our refugees to come back to Antwerp and don't omit to state the three favourable regulations....""The others have not come yet," he said coolly. "I had arranged for the ceremony to take place without me. I was being detained elsewhere. But behold I am here to take my vengeance in my own hands. When the others come they will be surprised to see their leader again, Beppo."The relation between invention and the engineering arts, and especially between invention and machines, will warrant a short review of the matter here; or even if this reason were wanting, there is a sufficient one in the fact that one of the first aims of an engineering apprentice is to invent something; and as the purpose here is, so far as the limits will permit, to say something upon each subject in which a beginner has an interest, invention must not be passed over.Lalage entered gently. He stood in the pitchy darkness for some time. He could not hear a sound. Presently his patience was rewarded. There was the click of a key in the door and something swished by him.The poor wretches, who expected to be killed at any moment, were driven into squares or the meadows, where they were exposed to the chilly night air, so that several babies perished. Only the next morning were the women and children allowed to leavethat is to say, they were told to take the shortest way to Maastricht.Descartes theory of the universe included, however, something more than extension (or matter) and motion. This was Thought. If we ask whence came the notion of Thought, our philosopher will answer that it was obtained by looking into himself. It was, in reality, obtained by looking into Aristotle, or into some text-book reproducing his metaphysics. But the Platonic element in his system enabled Descartes to isolate Thought much more completely than it had been isolated by Aristotle. To understand this, we must turn once more to the Timaeus. Plato made up his universe from space and Ideas. But the Ideas were too vague or too unintelligible for scientific purposes. Even mediaeval Realists were content to replace them by Aristotles much clearer doctrine of Forms. On the other hand, Aristotles First Matter was anything but a satisfactory conception. It was a mere abstraction; the390 unknowable residuum left behind when bodies were stripped, in imagination, of all their sensible and cogitable qualities. In other words, there was no Matter actually existing without Form; whereas Form was never so truly itself, never so absolutely existent, as when completely separated from Matter: it then became simple self-consciousness, as in God, or in the reasonable part of the human soul. The revolution wrought by substituting space for Aristotles First Matter will now become apparent. Corporeal substance could at once be conceived as existing without the co-operation of Form; and at the same stroke, Form, liberated from its material bonds, sprang back into the subjective sphere, to live henceforward only as pure self-conscious thought."2.
