ONE:Referring first to the saving effected by combining several operations in one machine, there is perhaps not one constructor in twenty that ever stops to consider what is really gained, and perhaps not one purchaser in a hundred that does the same thing. The impression is, that when one machine performs two operations it saves a second machine. A remarkable example of this exists in the manufacture of combination machines in Europe for working wood, where it is common to find complicated [69] machines that will perform all the operations of a joiner's shop, but as a rule only one thing at a time, and usually in an inconvenient manner, each operation being hampered and interfered with by another; and in changing from one kind of work to another the adjustments and changes generally equal and sometimes exceed the work to be done. What is stranger still is, that such machines are purchased, when their cost often equals that of separate machines to perform the same work.According to Sir A. Grant, it is by the mystical and poetical side of his nature that Plato differs from Aristotle. The one aspired to a truth above the truth of scientific knowledge; the other to methodised experience and the definite.182 Now, setting aside the question whether there is any truth above the truth of scientific knowledge, we doubt very much whether Plato believed in its existence. He held that the most valuable truth was that which could be imparted to others by a process even more rigorous than mathematical reasoning; and there was no reality, however transcendent, that he did not hope to bring within the grasp of a dialectic without which even the meanest could not be understood. He did, indeed, believe that, so far, the best and wisest of mankind had owed much more to a divinely implanted instinct than to any conscious chain of reflection; but he distinctly293 asserted the inferiority of such guidance to the light of scientific knowledge, if this could be obtained, as he hoped that it could. On the other hand, Aristotle was probably superior to Plato as a poet; and in speaking about the highest realities he uses language which, though less rich and ornate than his masters, is not inferior to it in force and fervour; while his metaphysical theories contain a large element of what would now be considered mysticism, that is, he often sees evidence of purpose and animation where they do not really exist. His advantage in definiteness is, of course, indisputable, but this was, perhaps, because he came after Plato and profited by his lessons.
ONE:Lawrence was profoundly interested in what Prout had to say. The latter had given far more information than he had imagined.
ONE:CHAPTER XXXIX. DESIGNING MACHINES.Whatever may have been the errors into which Socrates fell, he did not commit the fatal mistake of compromising his ethical doctrine by associating it indissolubly with his metaphysical opinions. Religion, with him, instead of being the source and sanction of all duty, simply brought in an additional dutythat of gratitude to the gods for their goodness. We shall presently see where he sought for the ultimate foundation of morality, after completing our survey of the dialectic method with which it was so closely connected. The induction of Socrates, when it went beyond that kind of analogical reasoning which we have just been considering, was mainly abstraction, the process by which he obtained those general conceptions or definitions which played so great a part in his philosophy. Thus, on comparing the different virtues, as commonly distinguished, he found that they all agreed in requiring knowledge, which he accordingly concluded to be the essence of virtue. So other moralists have been led to conclude that right actions resemble one another in their felicific quality, and In that alone. Similarly, political economists find, or formerly found (for we do not wish to be positive on the matter), that a common characteristic of all industrial employments is the desire to secure the maximum of profit with the minimum of trouble. Another comparison shows that value depends on the relation between supply and demand. Aesthetic enjoyments of every kind resemble one another by including an element of ideal emotion. It is a common characteristic of all cognitions that they are151 constructed by association out of elementary feelings. All societies are marked by a more or less developed division of labour. These are given as typical generalisations which have been reached by the Socratic method. They are all taken from the philosophic sciencesthat is, the sciences dealing with phenomena which are partly determined by mind, and the systematic treatment of which is so similar that they are frequently studied in combination by a single thinker, and invariably so by the greatest thinkers of any. But were we to examine the history of the physical sciences, we should find that this method of wide comparison and rapid abstraction cannot, as Francis Bacon imagined, be successfully applied to them. The facts with which they deal are not transparent, not directly penetrable by thought; hence they must be treated deductively. Instead of a front attack, we must, so to speak, take them in the rear. Bacon never made a more unfortunate observation than when he said that the syllogism falls far short of the subtlety of Nature. Nature is even simpler than the syllogism, for she accomplishes her results by advancing from equation to equation. That which really does fall far short of her subtlety is precisely the Baconian induction with its superficial comparison of instances. No amount of observation could detect any resemblance between the bursting of a thunderstorm and the attraction of a loadstone, or between the burning of charcoal and the rusting a nail.
