TWO:Those who will may see in all this an anticipation of chemical substitution and double decomposition. We can assure them that it will be by no means the most absurd parallel discovered between ancient and modern ideas. It is possible, however, to trace a more real connexion between the Aristotelian physics and mediaeval thought. We do not of361 course mean the scholastic philosophy, for there never was the slightest doubt as to its derivation; we allude to the alchemy and astrology which did duty for positive science during so many centuries, and even overlapped it down to the time of Newton, himself an ardent alchemist. The superstitions of astrology originated independently of the peripatetic system, and probably long before it, but they were likely to be encouraged by it instead of being repressed, as they would have been by a less anthropomorphic philosophy. Aristotle himself, as we have seen, limited the action of the heavens on the sublunary sphere to their heating power; but, by crediting them with an immortal reason and the pursuit of ends unknown to us, he opened a wide field for conjecture as to what those ends were, and how they could be ascertained. That the stars and planets were always thinking and acting, but never about our affairs, was not a notion likely to be permanently accepted. Neither was it easy to believe that their various configurations, movements, and names (the last probably revealed by themselves) were entirely without significance. From such considerations to the casting of horoscopes is not a far remove. The Aristotelian chemistry would still more readily lend itself to the purposes of alchemy. If Nature is one vast process of transmutation, then particular bodies, such as the metals, not only may, but must be convertible into one another. And even those who rejected Aristotles logic with scorn still clung to his natural philosophy when it flattered their hopes of gain. Bacon kept the theory of substantial forms. His originality consisted in looking for a method by which any form, or assemblage of forms might be superinduced at pleasure on the underlying matter. The real development of knowledge pursued a far different course. The great discoverers of the sixteenth and seventeenth centuries achieved their success by absolutely reversing the method of Aristotle, by bringing into fruitful contact principles which he had condemned to barren isolation.362 They carried terrestrial physics into the heavens; they brought down the absoluteness and eternity of celestial law to earth; they showed that Aristotles antithetical qualities were merely quantitative distinctions. These they resolved into modes of motion; and they also resolved all motions into one, which was both rectilinear and perpetual. But they and their successors put an end to all dreams of transmutation, when they showed by another synthesis that all matter, at least within the limits of our experience, has the changeless consistency once attributed exclusively to the stellar spheres.Such, as it seems to us, is the proper spirit in which we should approach the great thinker whose works are to occupy us in this and the succeeding chapter. No philosopher has ever offered so extended and vulnerable a front to hostile criticism. None has so habitually provoked reprisals by his own incessant and searching attacks on all existing professions, customs, and beliefs. It might even be maintained that none has used the weapons of controversy with more unscrupulous zeal. And it might be added that he who dwells so much on the importance of consistency has occasionally denounced and ridiculed the very principles which he elsewhere upholds as demonstrated truths. It was an easy matter for others to complete the work of destruction which he had begun. His system seems at first sight to be made up of assertions, one more outrageous than another. The ascription of an objective concrete separate reality to verbal abstractions is assuredly the most astounding paradox ever173 maintained even by a metaphysician. Yet this is the central article of Platos creed. That body is essentially different from extension might, one would suppose, have been sufficiently clear to a mathematician who had the advantage of coming after Leucippus and Democritus. Their identity is implicitly affirmed in the Timaeus. That the soul cannot be both created and eternal; that the doctrine of metempsychosis is incompatible with the hereditary transmission of mental qualities; that a future immortality equivalent to, and proved by the same arguments as, our antenatal existence, would be neither a terror to the guilty nor a consolation to the righteous:are propositions implicitly denied by Platos psychology. Passing from theoretical to practical philosophy, it might be observed that respect for human life, respect for individual property, respect for marriage, and respect for truthfulness, are generally numbered among the strongest moral obligations, and those the observance of which most completely distinguishes civilised from savage man; while infanticide, communism, promiscuity, and the occasional employment of deliberate deceit, form part of Platos scheme for the redemption of mankind. We need not do more than allude to those Dialogues where the phases and symptoms of unnameable passion are delineated with matchless eloquence, and apparently with at least as much sympathy as censure. Finally, from the standpoint of modern science, it might be urged that Plato used all his powerful influence to throw back physical speculation into the theological stage; that he deliberately discredited the doctrine of mechanical causation which, for us, is the most important achievement of early Greek thought; that he expatiated on the criminal folly of those who held the heavenly bodies to be, what we now know them to be, masses of dead matter with no special divinity about them; and that he proposed to punish this and other heresies with a severity distinguishable from the fitful fanaticism of his native city only by its more disciplined and rigorous application.
THREE:The faces of the dies remain parallel, no matter how large the piece may be that is operated upon, while with a trip-hammer, the top die moves in an arc described from the trunnions of the helve, and the faces of the dies can only be parallel when in one position, or when operating on pieces of a certain depth. This feature of parallel movement with the dies of crank-hammers is of great importance on some kinds of work, and especially so for machine-forgings where the size or depth of the work is continually being varied.We first drove through the suburb Montigny-sur-Sambre, which shared the fate of Jumet, and was entirely destroyed by fire. After leaving the town we went in the direction of Chatelet, where we found an immense battle-field. Terrific fighting must have taken place here, for the number of buried was enormous. On a wide stretch of land we saw a great number of mounds, with crosses, and covered with quicklime. On the crosses the numbers are given of the brave who fell there. So I read, for example:

THREE:"We won't bother about the drawing-room," Hetty said gaily. "That can take care of itself for the present. Two fans and a bulrush as somebody says. And the other rooms, so long as they are light, won't matter. But the dining-room must be quite the thing. Oh, if you could only afford to get the lovely oak we saw at Capper's! We must think of you alone, just at first, Gordon."We trust that the steps of a difficult argument have been made clear by the foregoing analysis; and that the whole process has been shown to hinge on the ambiguous use of such notions as the individual and the community, of which the one is paradoxically construed as a plurality and the other as a unity; justice, which is alternately taken in the sense of control exercised by the worthiest, control of passion in the general interest, control of our passions in the interest of others, and control of the same passions in our own interest; and wisdom or reason, which sometimes means any kind of excellence, sometimes the excellence of a harmonious society, and sometimes the excellence of a well-balanced mind. Thus, out of self-regarding virtue social virtue is elicited, the whole process being ultimately conditioned by that identifying power which was at once the strength and the weakness of Platos genius.

THREE:A walking excursion of one day took me to201 Brussels. I might have done it in a few hours less, but I lost my way in the wood-paths near Brussels, for at a certain moment I read on a finger-post, "Brussels four miles"; and after walking for a long time, and wondering whether I should ever finish those four miles, I read suddenly: "Brusselseight miles!" That gave me such a shock that once more I had nearly taken the wrong way.
