The Age of Wonder Read online

  The notion of an infinite, mysterious Nature, waiting to be discovered or seduced into revealing all her secrets, was widely held. Scientific instruments played an increasingly important role in this process of revelation, allowing man not merely to extend his senses passively — using the telescope, the microscope, the barometer — but to intervene actively, using the voltaic battery, the electrical generator, the scalpel or the air pump. Even the Montgolfier balloon could be seen as an instrument of discovery, or indeed of seduction.

  There was, too, a subtle reaction against the idea of a purely mechanistic universe, the mathematical world of Newtonian physics, the hard material world of objects and impacts. These doubts, expressed especially in Germany, favoured a softer ‘dynamic’ science of invisible powers and mysterious energies, of fluidity and transformations, of growth and organic change. This is one of the reasons that the study of electricity (and chemistry in general) became the signature science of the period; though astronomy itself, once the exemplary science of the Enlightenment, would also be changed by Romantic cosmology.

  The ideal of a pure, ‘disinterested’ science, independent of political ideology and even religious doctrine, also began slowly to emerge. The emphasis on a secular, humanist (even atheist) body of knowledge, dedicated to the ‘benefit of all mankind’, was particularly strong in Revolutionary France. This would soon involve Romantic science in new kinds of controversy: for instance, whether it could be an instrument of the state, in the case of inventing weapons of war. Or a handmaiden of the Church, supporting the widely held view of ‘Natural theology’, in which science reveals evidence of a divine Creation or intelligent design.

  With these went the new notion of a popular science, a people’s science. The scientific revolution of the late seventeenth century had promulgated an essentially private, elitist, specialist form of knowledge. Its lingua franca was Latin, and its common currency mathematics. Its audience was a small (if international) circle of scholars and savants. Romantic science, on the other hand, had a new commitment to explain, to educate, to communicate to a general public.

  This became the first great age of the public scientific lecture, the laboratory demonstration and the introductory textbook, often written by women. It was the age when science began to be taught to children, and the ‘experimental method’ became the basis of a new, secular philosophy of life, in which the infinite wonders of Creation (whether divine or not) were increasingly valued for their own sake. It was a science that, for the first time, generated sustained public debates, such as the great Regency controversy over ‘Vitalism’: whether there was such a thing as a life force or principle, or whether men and women (or animals) had souls.

  Finally, it was the age which challenged the elite monopoly of the Royal Society, and saw the foundation of scores of new scientific institutions, mechanics institutes and ‘philosophical’ societies, most notably the Royal Institution in Albemarle Street in 1799, the Geological Society in 1807, the Astronomical Society in 1820, and the British Association for the Advancement of Science in 1831.

  Much of this transition from Enlightenment to Romantic science is expressed in the paintings of Joseph Wright of Derby. Closely attached to the Lunar Society, and the friend of Erasmus Darwin and Joseph Priestley, Wright became a dramatic painter of experimental and laboratory scenes which reinterpreted late-eighteenth-century Enlightenment science as a series of mysterious, romantic moments of revelation and vision. The calm, glowing light of reason is surrounded by the intense, psychological chiaroscuro associated with Georges de la Tour. This is most evident in the famous series of scientific demonstration scenes painted at the height of his career: The Orrery (1766, Derby City Museum and the frontispiece of this book), The Air Pump (1767, National Gallery, London) and The Alchemist (1768, Derby City Museum). But these memorable paintings also ask whether Romantic science contained terror as well as wonder: if discovery and invention brought new dread as well as new hope into the world. We have certainly inherited this dilemma.

  The Age of Wonder aims to raise and reflect upon such questions. Yet in the end the book remains a narrative, a piece of biographical storytelling. It tries to capture something of the inner life of science, its impact on the heart as well as on the mind. In the broadest sense it aims to present scientific passion, so much of which is summed up in that childlike, but infinitely complex word, wonder. Plato argued that the notion of ‘wonder’ was central to all philosophical thought: ‘In Wonder all Philosophy began: in Wonder it ends…But the first Wonder is the Offspring of Ignorance; the last is the Parent of Adoration.’ 4

  Wonder, in other words, goes through various stages, evolving both with age and with knowledge, but retaining an irreducible fire and spontaneity. This seems to be the implication of Wordsworth’s famous lyric of 1802, which was inspired not by Newton’s prism, but by Nature’s:

  My heart leaps up when I behold

  A rainbow in the sky;

  So was it when my life began;

  So is it now I am a man;

  So be it when I shall grow old,

  Or let me die! …5

  This book is centred on two scientific lives, those of the astronomer William Herschel and the chemist Humphry Davy. Their discoveries dominate the period, yet they offer two almost diametrically opposed versions of the Romantic ‘scientist’, a term not coined until 1833, after they were both dead. It also gives an account of their assistants and protégés, who eventually became much more than that, and handed on the flame to the very different world of professional Victorian science. But it draws in many other lives, and it is interrupted by many episodes of scientific endeavour and high adventure so characteristic of the Romantic spirit: ballooning, exploring, soul-hunting. These were all part of the great journey.♣

  It is also held together by, as a kind of chorus figure or guide, a scientific Virgil. It is no coincidence that he began his career a young and naïve scientific traveller, an adventurer and secret journal-keeper. However, he ended it as the longest-serving, most experienced and most domineering President of the Royal Society: the botanist, diplomat and éminence grise Sir Joseph Banks. As a young man Banks sailed with Captain Cook round the world, setting out in 1768 on that perilous three-year voyage into the unknown. This voyage may count as one of the earliest distinctive exploits of Romantic science, not least because it involved a long stay in a beautiful but ambiguous version of Paradise — Otaheite, or the South Pacific island of Tahiti.

Various versions of the story began to appear after his death in 1727. It appears in Stukeley’s unpublished Memoir of Newton, originally written in 1727, but not given to the Royal Society in manuscript until 1752; in unpublished notes for a biography by his nephew John Conduit; and for the first time in print in Voltaire’s Letters on the English Nation (1734). Part of the power of the story was that it replaced the sacred Biblical account of the Fall from Innocence in Genesis (Eve and the apple) with a secular parable of the Ascent to Knowledge. See Patricia Fara, Newton: The Making of Genius (2005); and for a broad visionary perspective, Jacob Bronowski’s scientific classic The Ascent of Man (1973).

  Joseph Banks in Paradise

  1

  On 13 April 1769, young Joseph Banks, official botanist to HM Bark Endeavour, first clapped eyes on the island of Tahiti, 17 degrees South, 149 degrees Wes
t. He had been told that this was the location of Paradise: a wonderful idea, although he did not quite believe it.

  Banks was twenty-six years old, tall and well-built, with an appealing bramble of dark curls. By temperament he was cheerful, confident and adventurous: a true child of the Enlightenment. Yet he had thoughtful eyes and, at moments, a certain brooding intensity: a premonition of a quite different sensibility, the dreaming inwardness of Romanticism. He did not like to give way to it. So he kept good company with his shipmates, and had carefully maintained his physical fitness throughout the first eight months of the voyage. He regarded himself — ‘thank god’ — as in as good mental and physical trim as a man could be. When occasionally depressed, he did vigorous jumping ‘rope exercises’ in his cabin, once nearly breaking his leg while skipping.1

  He was capable of working patiently for hours on end in the extremely cramped conditions on board. The quarterdeck cabin, which he shared with his friend Dr Daniel Solander, was approximately eight feet by ten. He had adopted a strict daily routine of botanical drawing, electrical experiments, animal dissections, deck-walking, bird-shooting (when available) and journal-writing. He constantly fished specimens from the sea, shot or netted wild birds, and observed meteorological phenomena, such as the beautiful ‘lunar rainbows’. When his gums had begun bleeding ominously with the onset of scurvy, he had calmly treated himself with a specially pre-prepared syrup (‘Dr Hume’s mixture’) of concentrated lemon juice, taking precisely six ounces a day.2 Within a week he was cured.

  Just occasionally young Banks’s scientific enthusiasm turned to explosive impatience. When rudely prevented from carrying out any botanical field trips by the Spanish Consul at Rio de Janeiro, and confined for three weeks to the sweltering ship in the harbour at Rio, he wrote colourfully to a friend at the Royal Society: ‘You have heard of Tantalus in hell, you have heard of the French man laying swaddled in linen between two of his Mistresses both naked using every possible means to excite desire. But you have never heard of a tantalized wretch who has born his situation with less patience than I have done mine. I have cursed, swore, raved, stamped.’3 Banks did however unofficially slip over the side at night to collect wild seeds and plants, a hoard which included the exotic purple bougainvillea.

  Once among the Polynesian isles, Banks spent hours at the topgallant masthead, his large form crouched awkwardly in the crow’s nest, looking for landfall beneath the heavy tropical cloudbase. At night the crew would hear distant surf roaring through the dark. Now at last he gazed out at the fabled blue lagoon, the black volcanic sand, and the intriguing palm trees (Linnaeus’s Arecaceae). Above the beach the precipitous hills, dense with dark-green foliage and gleaming with white streams, rose sharply to 7,000 feet. On the naval chart Banks noted that the place was marked, prosaically enough, ‘Port Royal Bay, King George the Third’s Island’. ‘As soon as the anchors were well down the boats were hoisted out and we all went ashore where we were met by some hundreds of the inhabitants whose faces at least gave evident signs that we were not unwelcome guests, tho they at first hardly dare approach us. After a little time they became very familiar. The first who aproachd us came creeping almost on his hands and knees and gave us a green bough the token of peace.’

  Taking the hint, all the British shore party pulled down green boughs from the surrounding palm trees and carried them along the beach, waving them like ceremonial parasols. Eventually they were shown an idyllic spot close by a stream, where it was indicated that they could set up camp. The green boughs were thrown down in a great pile on the sand, ‘and thus peace was concluded’. Here the British settlement known as Fort Venus was to be established: ‘We then walkd into the woods followd by the whole train to whom we gave beads and small presents. In this manner we walked for 4 or 5 miles under groves of Cocoa nut and Bread fruit trees loaded with a profusion of fruit and giving the most gratefull shade I have ever experienced. Under these were the habitations of the people most of them without walls. In short the scene we saw was the truest picture of an Arcadia of which we were going to be Kings that the imagination can form.’

  As the men walked back, feeling dangerously like royalty, the Tahitian girls draped them with flowers, offered ‘all kind of civilities’ and gestured invitingly towards the coconut mats spread in the shade. Banks felt, reluctantly, that since islanders’ houses were ‘entirely without walls’ it was not quite the moment to ‘put their politeness to every test’. He would not have failed to have done so ‘had circumstances been more favourable’.4

  Tahiti lies roughly east-west just below the 17th parallel, one of the largest of what are now the Society Islands, roughly halfway between Peru and Australia. It is shaped not unlike a figure of eight, some 120 miles (‘40 leagues’) in circumference. Most of its foreshores are easily accessible, a series of broad, curving bays with black volcanic sands or pinkish-white coral beaches, fringed by coconut palms and breadfruit trees. But a few hundred yards inland, the ground rises sharply into an entirely different topography. The steep, densely wooded volcanic hills lead upwards to a remote and hostile landscape of deep gullies, sheer cliffs and perilous ledges.

  Contrary to legend, the Endeavour, commanded by Lieutenant James Cook, was not the first European ship to make landfall in Tahiti. Spanish expeditions, under Quiroz or Torres, had probably touched there in the late sixteenth century, and claimed it for Spain.5 A previous English expedition, under Captain Wallis of the Dolphin, had definitely landed there in 1767, when it was described as ‘romantic’, and claimed for England. A French expedition under Louis-Antoine de Bougainville had anchored there the following year, and claimed it for France.

  The French had racily christened Tahiti ‘La Nouvelle Cythère’, the New Island of Love. Banks’s opposite number, the French botanist Philibert Commerson (who named the bougainvillea after his captain), had published a sensational letter in the Mercure de France describing Tahiti as a sexual ‘Utopia’. It proved that Jean-Jacques Rousseau was right about the existence of the Noble Savage. But then, the French had only spent nine days on the island.♣

  Cook was more sceptical, and had every member of his crew (including the officers) examined for venereal infections four weeks before arriving, by their surgeon Jonathan Monkhouse. He issued a series of Landing Instructions, which stated that the first rule of conduct ashore was civilised behaviour: ‘To Endeavour by every fair means to cultivate a Friendship with the Natives and to treat them with all Imaginable Humanity.’6 It was no coincidence that he enshrined the ship’s own name in this instruction.

  Joseph Banks had his own views on Paradise. He gave a whimsical account of his first night ashore in his Endeavour Journal. He dined deliciously on dressed fish and breadfruit, next to a Tahitian queen, who ‘did me the honour with very little invitation to squat down on the mats close by me’. However, the queen was ‘ugly enough in conscience’. Banks then noticed a very pretty girl, ‘with a fire in her eyes’ and white hibiscus in her hair, lingering in the ‘common crowd’ at the door. He encouraged her to come and sit on his other side, studiously ignored the queen for the rest of the evening, and ‘loaded’ the Polynesian beauty with bead necklaces and every compliment he could manage. ‘How this would have ended is hard to say,’ he observed later. In fact the amorous party broke up abruptly when it was discovered that his friend Solander had had a snuffbox picked from his pocket, and a fellow officer had lost ‘a pair of opera glasses’. It is not explained why he had brought opera glasses ashore in the first place.

  This thieving proved to be completely customary in Tahiti, and led to many painful misunderstandings on both sides. The first occurred the following day, when a Tahitian quite openly made off with a marine’s musket, and was immediately shot dead by a punctilious guard. Banks quickly grasped that some quite different notion of property must be involved, and noted grimly: ‘We retird to the ship not well pleasd with the days expedition, guilty no doubt in some measure of the death of a man who the
most severe laws of equity would not have condemnd to so severe a punishment. No canoes about the ship this morning, indeed we could not expect any as it is probable that the news of our behaviour yesterday was now known every where, a circumstance which will doubtless not increase the confidence of our friends the Indians.’ Nonetheless, to Banks’s relief and evident surprise, good relations were restored within twenty-four hours.

  The Endeavour expedition remained for three months on Tahiti. Its main object was to observe a Transit of Venus across the face of the sun. (Cook stated that this was the reason their settlement was named Fort Venus, though his junior officers gave a different explanation.) This was due on the morning of 3 June 1769, and there would be no other transit for the next hundred years (not until 1874). It was a unique chance to establish the solar parallax, and hence the distance of the sun from the earth. This calculation depended on observing the exact timing at which the silhouette of Venus first entered, and then exited from, the sun’s disc.

  Banks was not part of the astronomical team, but when the expedition’s quadrant was stolen one night shortly before the transit was due, he reacted with characteristic energy and courage. He knew that without this large and exquisitely calibrated brass instrument, used to measure precise astronomical angles, the entire observation would be rendered valueless. Not waiting for Cook or his marine guards, Banks roused the expedition’s official astronomer, William Green, and set off immediately on foot in pursuit of the thief. In the dizzy heat, Banks followed the trail far up into the hills, accompanied only by a reluctant Green, one unarmed midshipman and a Tahitian interpreter. They penetrated seven miles inland through the Tahitian jungle, further than any European had been before: ‘The weather was excessive hot, the Thermometer before we left the tents up at 91 made our journey very tiresome. Sometimes we walk’d sometimes we ran when we imagind (which we sometimes did) that the chase was just before us till we arrivd at the top of a hill about 4 miles from the tents. From this place [the interpreter] Tubourai shew’d us a point about 3 miles off and made us understand that we were not to expect the instrument till we got there. We now considerd our situation. No arms among us but a pair of pocket pistols which I always carried; going at least 7 miles from our fort where the Indians might not be quite so submissive as at home; going also to take from them a prize for which they had ventured their lives.’7
