第156章 CHAPTER III(47)

Yet the effect of those troubles was that schemes of political and religious reform were generally regarded with suspicion and contempt. During twenty years the chief employment of busy and ingenious men had been to frame constitutions with first magistrates, without first magistrates, with hereditary senates, with senates appointed by lot, with annual senates, with perpetual senates. In these plans nothing was omitted. All the detail, all the nomenclature, all the ceremonial of the imaginary government was fully set forth, Polemarchs and Phylarchs, Tribes and Galaxies, the Lord Archon and the Lord Strategus. Which ballot boxes were to be green and which red, which balls were to be of gold and which of silver, which magistrates were to wear hats and which black velvet caps with peaks, how the mace was to be carried and when the heralds were to uncover, these, and a hundred more such trifles, were gravely considered and arranged by men of no common capacity and learning.181 But the time for these visions had gone by; and, if any steadfast republican still continued to amuse himself with them, fear of public derision and of a criminal information generally induced him to keep his fancies to himself. It was now unpopular and unsafe to mutter a word against the fundamental laws of the monarchy: but daring and ingenious men might indemnify themselves by treating with disdain what had lately been considered as the fundamental laws of nature. The torrent which had been dammed up in one channel rushed violently into another. The revolutionary spirit, ceasing to operate in politics, began to exert itself with unprecedented vigour and hardihood in every department of physics. The year 1660, the era of the restoration of the old constitution, is also the era from which dates the ascendency of the new philosophy. In that year the Royal Society, destined to be a chief agent in a long series of glorious and salutary reforms, began to exist.182In a few months experimental science became all the mode. The transfusion of blood, the ponderation of air, the fixation of mercury, succeeded to that place in the public mind which had been lately occupied by the controversies of the Rota. Dreams of perfect forms of government made way for dreams of wings with which men were to fly from the Tower to the Abbey, and of doublekeeled ships which were never to founder in the fiercest storm. All classes were hurried along by the prevailing sentiment. Cavalier and Roundhead, Churchman and Puritan, were for once allied. Divines, jurists, statesmen, nobles, princes, swelled the triumph of the Baconian philosophy. Poets sang with emulous fervour the approach of the golden age. Cowley, in lines weighty with thought and resplendent with wit, urged the chosen seed to take possession of the promised land flowing with milk and honey, that land which their great deliverer and lawgiver had seen, as from the summit of Pisgah, but had not been permitted to enter.183 Dryden, with more zeal than knowledge, joined voice to the general acclamation to enter, and foretold things which neither he nor anybody else understood. The Royal Society, he predicted, would soon lead us to the extreme verge of the globe, and there delight us with a better view of the moon.184 Two able and aspiring prelates, Ward, Bishop of Salisbury, and Wilkins, Bishop of Chester, were conspicuous among the leaders of the movement. Its history was eloquently written by a younger divine, who was rising to high distinction in his profession, Thomas Sprat, afterwards Bishop of Rochester. Both Chief Justice Hale and Lord Keeper Guildford stole some hours from the business of their courts to write on hydrostatics. Indeed it was under the immediate direction of Guildford that the first barometers ever exposed to sale in London were constructed.185 Chemistry divided, for a time, with wine and love, with the stage and the gaming table, with the intrigues of a courtier and the intrigues of a demagogue, the attention of the fickle Buckingham. Rupert has the credit of having invented mezzotinto; from him is named that curious bubble of glass which has long amused children and puzzled philosophers. Charles himself had a laboratory at Whitehall, and was far more active and attentive there than at the council board. It was almost necessary to the character of a fine gentleman to have something to say about air pumps and telescopes; and even fine ladies, now and then, thought it becoming to affect a taste for science, went in coaches and six to visit the Gresham curiosities, and broke forth into cries of delight at finding that a magnet really attracted a needle, and that a microscope really made a fly loom as large as a sparrow.186In this, as in every great stir of the human mind, there was doubtless something which might well move a smile. It is the universal law that whatever pursuit, whatever doctrine, becomes fashionable, shall lose a portion of that dignity which it had possessed while it was confined to a small but earnest minority, and was loved for its own sake alone. It is true that the follies of some persons who, without any real aptitude for science, professed a passion for it, furnished matter of contemptuous mirth to a few malignant satirists who belonged to the preceding generation, and were not disposed to unlearn the lore of their youth.187 But it is not less true that the great work of interpreting nature was performed by the English of that age as it had never before been performed in any age by any nation. The spirit of Francis Bacon was abroad, a spirit admirably compounded of audacity and sobriety. There was a strong persuasion that the whole world was full of secrets of high moment to the happiness of man, and that man had, by his Maker, been entrusted with the key which, rightly used, would give access to them. There was at the same time a conviction that in physics it was impossible to arrive at the knowledge of general laws except by the careful observation of particular facts. Deeply impressed with these great truths, the professors of the new philosophy applied themselves to their task, and, before a quarter of a century had expired, they had given ample earnest of what has since been achieved. Already a reform of agriculture had been commenced. New vegetables were cultivated. New implements of husbandry were employed. New manures were applied to the soil.188 Evelyn had, under the formal sanction of the Royal Society, given instruction to his countrymen in planting. Temple, in his intervals of leisure, had tried many experiments in horticulture, and had proved that many delicate fruits, the natives of more favoured climates, might, with the help of art, be grown on English ground. Medicine, which in France was still in abject bondage, and afforded an inexhaustible subject of just ridicule to Moliere, had in England become an experimental and progressive science, and every day made some new advance in defiance of Hippocrates and Galen. The attention of speculative men had been, for the first time, directed to the important subject of sanitary police. The great plague of 1665 induced them to consider with care the defective architecture, draining, and ventilation of the capital. The great fire of 1666 afforded an opportunity for effecting extensive improvements. The whole matter was diligently examined by the Royal Society; and to the suggestions of that body must be partly attributed the changes which, though far short of what the public welfare required, yet made a wide difference between the new and the old London, and probably put a final close to the ravages of pestilence in our country.189 At the same time one of the founders of the Society, Sir William Petty, created the science of political arithmetic, the humble but indispensable handmaid of political philosophy. No kingdom of nature was left unexplored. To that period belong the chemical discoveries of Boyle, and the earliest botanical researches of Sloane. It was then that Ray made a new classification of birds and fishes, and that the attention of Woodward was first drawn towards fossils and shells. One after another phantoms which had haunted the world through ages of darkness fled before the light.
