FORE:Maitrank looked up with a wolfish gleam in his eyes.Founding and casting relate to forming parts of machinery by pouring melted metal into moulds, the force of gravity alone being sufficient to press or shape it into even complicated forms. As a process for shaping such metal as is not injured by the high degree of heat required in melting, moulding is the cheapest and most expeditious of all means, even for forms of regular outline, while the importance of moulding in producing irregular forms is such that without this process the whole system of machine construction would have to be changed. Founding operations are divided into two classes, known technically as green sand moulding, and loam or dry sand moulding; the first, when patterns or duplicates are used to form the moulds, and the second, when the moulds are built by hand without the aid of complete patterns. Founding involves a knowledge of mixing and melting metals such as are used in machine construction, the preparing and setting of cores for the internal displacement of the metal, cooling and shrinking strains, chills, and many other things that are more or less special, and can only be learned and understood from actual observation and practice.

FORE:Rhetoric conferred even greater power in old Athens than in modern England. Not only did mastery of expression lead to public employment; but also, as every citizen was permitted by law to address his assembled fellow-countrymen and propose measures for their acceptance, it became a direct passport to supreme political authority. Nor was this all. At Athens the employment of professional advocates was not98 allowed, and it was easy to prosecute an enemy on the most frivolous pretexts. If the defendant happened to be wealthy, and if condemnation involved a loss of property, there was a prejudice against him in the minds of the jury, confiscation being regarded as a convenient resource for replenishing the national exchequer. Thus the possession of rhetorical ability became a formidable weapon in the hands of unscrupulous citizens, who were enabled to extort large sums by the mere threat of putting rich men on their trial for some real or pretended offence. This systematic employment of rhetoric for purposes of self-aggrandisement bore much the same relation to the teaching of Protagoras and Gorgias as the open and violent seizure of supreme power on the plea of natural superiority bore to the theories of their rivals, being the way in which practical men applied the principle that truth is determined by persuasion. It was also attended by considerably less danger than a frank appeal to the right of the stronger, so far at least as the aristocratic party were concerned. For they had been taught a lesson not easily forgotten by the downfall of the oligarchies established in 411 and 404; and the second catastrophe especially proved that nothing but a popular government was possible in Athens. Accordingly, the nobles set themselves to study new methods for obtaining their ultimate end, which was always the possession of uncontrolled power over the lives and fortunes of their fellow-citizens. With wealth to purchase instruction from the Sophists, with leisure to practise oratory, and with the ability often accompanying high birth, there was no reason why the successors of Charmides and Critias should not enjoy all the pleasures of tyranny unaccompanied by any of its drawbacks. Here, again, a parallel suggests itself between ancient Greece and modern Europe. On the Continent, where theories of natural law are far more prevalent than with us, it is by brute force that justice is trampled down: the one great object of every ambitious99 intriguer is to possess himself of the military machine, his one great terror, that a stronger man may succeed in wresting it from him; in England the political adventurer looks to rhetoric as his only resource, and at the pinnacle of power has to dread the hailstorm of epigrammatic invective directed against him by abler or younger rivals.74

FORE:It is well known that Spinoza draws a sharp line of demarcation between the two attributes of Extension and Thought, which, with him, correspond to what are usually called body and mind. Neither attribute can act on the other. Mind receives no impressions from body, nor does body receive any impulses from mind. This proposition follows by rigorous logical necessity from the Platonic principle that mind is independent of body, combined with the Stoic principle that nothing but body can act on body, generalised into the wider principle that interaction implies homogeneity of nature. According to some critics, Spinozas teaching on this point constitutes a fatal flaw in his philosophy. How, it is asked, can we know that there is any such thing as body (or extension) if body cannot be perceived,for perceived it certainly cannot be without acting on our minds? The idea of infinite substance suggests a way out of the408 difficulty. I find in myself, Spinoza might say, the idea of extension. In fact, my mind is nothing but the idea of extension, or the idea of that idea, and so on through as many self-reflections as you please. At the same time, mind, or thought, is not itself extended. Descartes and the Platonists before him have proved thus much. Consequently I can conceive extension as existing independently of myself, and, more generally, of all thought. But how can I be sure that it actually does so exist? In this wise. An examination of thought leads me to the notion of something in which it residesa substance whose attribute it is. But having once conceived such a substance, I cannot limit it to a single attribute, nor to two, nor to any finite number. Limitation implies a boundary, and there can be no boundary assigned to existence, for existence by its very definition includes everything that is. Accordingly, whatever can be conceived, in other words whatever can be thought without involving a contradiction,an important reservation which I beg you to observe,must necessarily exist. Now extension involves no contradiction, therefore it exists,exists, that is to say, as an attribute of the infinite substance. And, by parity of reasoning, there must be an idea of extension; for this also can exist without involving a contradiction, as the simplest introspection suffices to show. You ask me why then I do not believe in gorgons and chimaeras. I answer that since, in point of fact, they do not exist, I presume that their notion involves a contradiction, although my knowledge of natural law is not sufficiently extended to show me where the contradiction lies. But perhaps science will some day be able to point out in every instance of a non-existing thing, where the contradiction lies, no less surely than it can now be pointed out in the case of impossible geometrical figures. In short, while other people travel straight from their sensations to an external world, Spinoza travels round to it by the idea of an infinite substance.564
