THREE:It is worthy of remark that in the Platonic Er?s we have the germor something more than the germof Aristotles whole metaphysical system.135 According to the usual law of speculative evolution, what was subjective in the one becomes objective in the other. With Plato the passion for knowledge had been merely the guiding principle of a few chosen spirits. With Aristotle it is the living soul of Nature, the secret spring of movement, from the revolution of the outermost starry sphere to the decomposition and recomposition of our mutable terrestrial elements; and from these again through the whole scale of organic life, up to the moral culture of man and the search for an ideally-constituted state. What enables all these myriad movements to continue through eternity, returning ever in an unbroken circle on themselves, is the yearning of unformed matterthat is to say, of unrealised powertowards the absolute unchanging actuality, the self-thinking thought, unmoved, but moving every other form of existence by the desire to participate in its ineffable perfection. Born of the Hellenic enthusiasm for beauty, this wonderful conception subsequently became incorporated with the official teaching of Catholic theology. What had once been a theme219 for ribald merriment or for rhetorical ostentation among the golden youth of Athens, furnished the motive for his most transcendent meditations to the Angel of the Schools; but the fire which lurked under the dusty abstractions of Aquinas needed the touch of a poet and a lover before it could be rekindled into flame. The eyes of Beatrice completed what the dialectic of Plato had begun; and the hundred cantos of her adorer found their fitting close in the love that moves the sun and the other stars.A world where ordering reason was not only raised to supreme power, but also jealously secluded from all communion with lower forms of existence, meant to popular imagination a world from which divinity had been withdrawn. The astronomical teaching of Anaxagoras was well calculated to increase a not unfounded alarm. Underlying the local tribal mythology of Athens and of Greece generally, was an older, deeper Nature-worship, chiefly directed towards those heavenly luminaries which shone so graciously on all men, and to which all men yielded, or were supposed to yield,41 grateful homage in return. Securus judicat orbis terrarum. Every Athenian citizen from Nicias to Strepsiades would feel his own belief strengthened by such a universal concurrence of authority. Two generations later, Plato held fast to the same conviction, severely denouncing its impugners, whom he would, if possible, have silenced with the heaviest penalties. To Aristotle, also, the heavenly bodies were something far more precious and perfect than anything in our sublunary sphere, something to be spoken of only in language of enthusiastic and passionate love. At a far later period Marcus Aurelius could refer to them as visible gods;32 and just before the final extinction of Paganism highly-educated men still offered up their orisons in silence and secresy to the moon.33 Judge, then, with what horror an orthodox public received Anaxagorass announcement that the moon shone only by reflected light, that she was an earthy body, and that her surface was intersected with mountains and ravines, besides being partially built over. The bright Seln, the Queen of Heaven, the most interesting and sympathetic of goddesses, whose phases so vividly recalled the course of human life, who was firmly believed to bring fine weather at her return and to take it away at her departure, was degraded into a cold, dark, senseless clod.34 Democritus observed that all this had been known a long time in the Eastern countries where he had travelled.C Possibly; but fathers of families could not have been more disturbed if it had been a brand-new discovery. The sun, too, they were told, was a red-hot stone larger than Peloponnesusa somewhat unwieldy size even for a Homeric god. Socrates, little as he cared about physical investigations generally, took this theory very seriously to heart, and42 attempted to show by a series of distinctions that sun-heat and fire-heat were essentially different from each other. A duller people than the Athenians would probably have shown far less suspicion of scientific innovations. Men who were accustomed to anticipate the arguments of an orator before they were half out of his mouth, with whom the extraction of reluctant admissions by cross-examination was habitually used as a weapon of attack and defence in the public law courts and practised as a game in private circleswho were perpetually on their guard against insidious attacks from foreign and domestic foeshad minds ready trained to the work of an inquisitorial priesthood. An Athenian, moreover, had mythology at his fingers ends; he was accustomed to see its leading incidents placed before him on the stage not only with intense realism, but with a systematic adaptation to the demands of common experience and a careful concatenation of cause and effect, which gave his belief in them all the force of a rational conviction while retaining all the charm of a supernatural creed. Then, again, the constitution of Athens, less than that of any other Greek State, could be worked without the devoted, self-denying co-operation of her citizens, and in their minds sense of duty was inseparably associated with religious belief, based in its turn on mythological traditions. A great poet has said, and said truly, that Athens was on the will of man as on a mount of diamond set, but the crystallising force which gave that collective human will such clearness and keenness and tenacity was faith in the protecting presence of a diviner Will at whose withdrawal it would have crumbled into dust. Lastly, the Athenians had no genius for natural science; none of them were ever distinguished as savants. They looked on the new knowledge much as Swift looked on it two thousand years afterwards. It was, they thought, a miserable trifling waste of time, not productive of any practical good, breeding conceit in young men, and quite unworthy of receiving any attention from orators, soldiers, and43 statesmen. Pericles, indeed, thought differently, but Pericles was as much beyond his age when he talked about Nature with Anaxagoras as when he charged Aspasia with the government of his household and the entertainment of his guests.
FORE:With running dies, blanks may be clamped when a machine is in motion, and as the blank does not revolve, it may, when long, be supported in any temporary manner. The dies can be opened and closed by the driving power also, and no stopping of a machine is necessary; so that several advantages of considerable importance may be gained by mounting the dies in a running head, a plan which has been generally adopted in late years by machine tool makers both in England and America.Descartes had already accomplished a great simplification of the speculative problem by summing up all existence under the two heads of extension and thought. It remained to account for these, and to reduce them to a single idea. As we have seen, they were derived from Greek philosophy, and the bond which was to unite them must be sought for in the same direction. It will be remembered that the systems of Plato and Aristotle were bounded at either extremity by a determinate and by an indeterminate principle. With the one, existence ranged between the Idea of Good at the upper end of the scale and empty space at the lower; with the other, between absolute Thought and First Matter. It was by combining the two definite terms, space and thought, that Descartes had constructed his system; and after subtracting these the two indefinite terms remained. In one respect they were even more opposed to each other than were the terms with which they had been respectively associated. The Idea403 of Good represented unity, identity, and constancy, as against plurality, difference, and change; while Aristotles Matter was, by its very definition, multiform, fluctuating, and indeterminate. Nevertheless, there were equally important analogies traceable between them. No very clear account could be given of either, and both were customarily described by negatives. If Matter fell short of complete existence, the Good transcended all existence. If the one was a universal capacity for assuming Forms, the other was the source whence all Forms proceeded. When the distinctive characteristics of an individual were thought away, the question might well be mooted into which principle it would return. The ambiguous use of the word Power contributed still further to their identification, for it was not less applicable to the receptive than to the productive faculty. Now we have just seen into what importance the idea of Power suddenly sprang at the Renaissance: with Bruno it was the only abiding reality of Nature; with Hobbes it was the only object of human desire.
