The tourist more rarely visits Constantinople or studies the architecture of Sancta Sofia, but when he does, he is distinctly conscious of forces not quite the same. Justinian has not the simplicity of Charlemagne. The Eastern Empire showed an activity and variety of forces that classical Europe had never possessed. The navy of Nicephoras Phocas in the tenth century would have annihilated in half an hour any navy that Carthage or Athens or Rome ever set afloat. The dynamic scheme began by asserting rather recklessly that between the Pyramids (B.C. 3000), and the Cross (A.D. 300), no new force affected Western progress, and antiquarians may easily dispute the fact; but in any case the motive influence, old or new, which raised both Pyramids and Cross was the same attraction of power in a future life that raised the dome of Sancta Sofia and the Cathedral at Amiens, however much it was altered, enlarged, or removed to distance in space. Therefore, no single event has more puzzled historians than the sudden, unexplained appearance of at least two new natural forces of the highest educational value in mechanics, for the first time within record of history. Literally, these two forces seemed to drop from the sky at the precise moment when the Cross on one side and the Crescent on the other, proclaimed the complete triumph of the Civitas Dei . Had the Manichean doctrine of Good and Evil as rival deities been orthodox, it would alone have accounted for this simultaneous victory of hostile powers.
Of the compass, as a step towards demonstration of the dynamic law, one may confidently say that it proved, better than any other force, the widening scope of the mind, since it widened immensely the range of contact between nature and thought. The compass educated. This must prove itself as needing no proof.
Of Greek fire and gunpowder, the same thing cannot certainly be said, for they have the air of accidents due to the attraction of religious motives.
They belong to the spiritual world; or to the doubtful ground of Magic which lay between Good and Evil. They were chemical forces, mostly explosives, which acted and still act as the most violent educators ever known to man, but they were justly feared as diabolic, and whatever insolence man may have risked towards the milder teachers of his infancy, he was an abject pupil towards explosives. The Sieur de Joinville left a record of the energy with which the relatively harmless Greek fire educated and enlarged the French mind in a single night in the year 1249, when the crusaders were trying to advance on Cairo. The good king St. Louis and all his staff dropped on their knees at every fiery flame that flew by, praying -- "God have pity on us!" and never had man more reason to call on his gods than they, for the battle of religion between Christian and Saracen was trifling compared with that of education between gunpowder and the Cross.
The fiction that society educated itself, or aimed at a conscious purpose, was upset by the compass and gunpowder which dragged and drove Europe at will through frightful bogs of learning. At first, the apparent lag for want of volume in the new energies lasted one or two centuries, which closed the great epochs of emotion by the Gothic cathedrals and scholastic theology.
The moment had Greek beauty and more than Greek unity, but it was brief; and for another century or two, Western society seemed to float in space without apparent motion. Yet the attractive mass of nature's energy continued to attract, and education became more rapid than ever before. Society began to resist, but the individual showed greater and greater insistence, without realizing what he was doing. When the Crescent drove the Cross in ignominy from Constantinople in 1453, Gutenberg and Fust were printing their first Bible at Mainz under the impression that they were helping the Cross. When Columbus discovered the West Indies in 1492, the Church looked on it as a victory of the Cross. When Luther and Calvin upset Europe half a century later, they were trying, like St. Augustine, to substitute the Civitas Dei for the Civitas Romae . When the Puritans set out for New England in 1620, they too were looking to found a Civitas Dei in State Street; and when Bunyan made his Pilgrimage in 1678, he repeated St. Jerome. Even when, after centuries of license, the Church reformed its discipline, and, to prove it, burned Giordano Bruno in 1600, besides condemning Galileo in 1630 -- as science goes on repeating to us every day -- it condemned anarchists, not atheists. None of the astronomers were irreligious men; all of them made a point of magnifying God through his works; a form of science which did their religion no credit. Neither Galileo nor Kepler, neither Spinoza nor Descartes, neither Leibnitz nor Newton, any more than Constantine the Great -- if so much -- doubted Unity. The utmost range of their heresies reached only its personality.
This persistence of thought-inertia is the leading idea of modern history.
Except as reflected in himself, man has no reason for assuming unity in the universe, or an ultimate substance, or a prime-motor. The a priori insistence on this unity ended by fatiguing the more active -- or reactive -- minds; and Lord Bacon tried to stop it. He urged society to lay aside the idea of evolving the universe from a thought, and to try evolving thought from the universe. The mind should observe and register forces -- take them apart and put them together -- without assuming unity at all. "Nature, to be commanded, must be obeyed." "The imagination must be given not wings but weights." As Galileo reversed the action of earth and sun, Bacon reversed the relation of thought to force. The mind was thenceforth to follow the movement of matter, and unity must be left to shift for itself.
