The Age of Scientific Naturalism

John Tyndall died of poisoning. From 1890-93, this enthusiastic mountaineer found himself bedridden, struggling with illness. He was in the habit of taking doses of chloral hydrate at night to help him with his insomnia, and every other day some sulphate of magnesia for his constipation. Near the end, his wife, Louisa, 25 years his junior, administered the dosages to him.

In 1893, on a Monday morning, Tyndall asked Louisa for a spoonful of magnesium. It was dark, and his beside table was littered with bottles. Louisa took a bottle a poured a spoonful, serving it to his lips. He took a big gulp and, tasting it, said, “there is a curious sweet taste.” Immediately Louisa realized she had accidentally given him a spoonful of chloral. She turned to him and said, “John, I have given you chloral.” He replied, “yes, my poor darling, you have killed your John” (see account in “Mrs. Tyndall’s Fatal Error,” New York Times, 1893).

The great physicist John Tyndall died that same evening. Stricken with guilt, Louisa spent the rest of her life attempting to resurrect him. She collected his journals, correspondence, and all unfinished writings for the purpose of publishing a massive Life and Letters. No Life and Letter ever came to fruition. She died in 1940 at the age of 95.

Lightman and Reidy - The Age of Scientific NaturalismThe current volume under review is a renewed attempt to resurrect the life and work of John Tyndall. Edited by Bernie Lightman and Michael S. Reidy, The Age of Scientific Naturalism: Tyndall and his Contemporaries (2014), the essays in this collection originate from two conferences specifically organized around the work of Tyndall, including the “Evolutionary Naturalism Conference” held at York University in 2011 and “John Tyndall and Nineteenth-Century Science Workshop and Conference” held at Montana State University in 2012. Publisher Pickering & Chatto (publishers of the current volume) will also begin publishing Tyndall’s correspondence in 16 volumes, beginning in 2015.

The Age of Scientific Naturalism is divided into three parts. Part I, “John Tyndall,” highlights Tyndall’s “unflinching defence of a naturalistic world view” and the role he played “within the contested nature of science in the Victorian era.” Tyndall was known for his “flamboyant lectures, which mixed practised showmanship with extravagant experiments,” presenting “science as an exhilarating spectacle.” The essays in this first part stress Tyndall’s research and the construction of his public persona. Elizabeth Neswald’s opening essay, “Saving the World in the Age of Entropy,” connects Tyndall with philosophical threads and ideological biases of the mid-nineteenth century, particularly German naturaphilosophie. In his work, for example, Tyndall marginalized the law of entropy in “favour of a balanced world of cycles,” in much the same way that German materialists did, proposing a “living nature in an eternal process of becoming.” Tyndall emphasized “the role of the sun in supporting life,” and drew “a picture of a nature embodying organic unity.” This verges on “nature worship,” and Neswald emphasizes that Victorian religious agnosticism “differed little from Christian theology.” According to Neswald, “for Tyndall…god was nature.” Following the work of Ruth Barton, Stephen S. Kim, and Tess Cosslett, Neswald notes that “the use of religious language in works of popular science was widespread in this period,” and that Tyndall’s language was particularly indebted to the “natural supernaturalism” of Thomas Carlyle. “Tyndall’s private writings, his journals and letters, reveal a view of nature and the universe that sees a creative power that could not be fully comprehended through science alone.” In a letter to his close friend Thomas Archer Hirst, for instance, Tyndall writes that “the universe is a body with life within it, and among it, and through it, permeating its every fiber…Everything in nature is in the act of becoming another thing.” These sentiments were due to Tyndall’s reading of “German philosophers,” which he “imbibed them through the interpretations and writings of Thomas Carlyle, who himself was deeply indebted to German idealist and romantic philosophies.” Indeed, Tyndall was very much encrusted within this tradition, so much so that modern interpretations, such as viewing him as a progenitor of global warming, become problematic, as Joshua Howe shows in the following essay, “Getting Past the Greenhouse.” Howe criticizes the Tyndall Centre for Climate Change Research at the University of East Anglia in the United Kingdom for co-opting Tyndall as a forefather of modern climate science. Also criticizing recent “histories” of global warming, Howe writes that the “biography of global warming is ahistorical.” Such “presentist biography,” he argues, “has consequences for the way we understand the role of science in the twenty-first-century politics of climate change.” These stories “feed myths and misunderstandings about contemporary and historical issues, both academic and otherwise.” Jeremiah Rankin and Ruth Barton, in the next essay, “Tyndall, Lewes and Popular Representations of Scientific Authority in Victorian Britain,” compare the popular science writings of Tyndall and those of literary critic George Henry Lewes, showing how porous the boundaries between public and private science, the laboratory and the field, and the popularizer and practitioner, were during the mid-Victorian period. Both Tyndall and Lewes, they argue, “pursued scientific research, wrote for the periodical press, addressed topics beyond their specialist expertise, and devoted considerable effort to popularizing a naturalistic version of science.” Indeed, both men used many of the “same tropes in their self-representation as reliable and authoritative expositors of science.”

Part II, “Scientific Naturalism,” examines scientific naturalism itself, demonstrating that science was still in a state of flux in the late-nineteenth century. But this set of essays attempt to move beyond Frank Turner’s Between Science and Religion (1974). Who were the “scientific naturalists” turns out to be an increasingly complex question. Looking at some of the “less obvious scientific naturalists,” these essays go beyond the myopic focus on Huxley and Tyndall, and examine the complex personalities of Herbert Spencer, William Kingdon Clifford, William Huggins, and Alfred Newton. Spencer, for example, planted his philosophical roots in the soil of naturaphilosophie and evolutionary deism. According to Michael Taylor, in his “Herbert Spencer and the Metaphysical Roots of Evolutionary Naturalism,” Spencer underscored the “popular and fluid definitions of scientific naturalism.” Rather than an empiricist and materialist, Taylor argues, Spencer’s philosophical system reveals “elements of transcendentalism and rationalism, as well as an awareness of the limits of knowledge that verged on mysticism.” Spencer undoubtedly had metaphysical sources, such as Erasmus Darwin and Robert Chambers’ “evolutionary deism,” which “articulated a vision of cosmic evolution that presented a story of progress from the nebulae to human society.” Another metaphysical source was German transcendental biology or naturaphilosophie. Despite his neglect in contemporary works, Spencer’s impact on Victorian intellectual life was immense. Taylor persuasively argues that “Spencer’s evolutionary naturalism had its roots deep in metaphysical theories that were far removed from empiricism and materialism.” Josipa Petrunic follows with an essay on the “Evolutionary Mathematics” of Clifford and his beliefs in the Spencerian process of evolution, which included the search for a foundation for a new morality within scientific naturalism. In the end, according to Petrunic, Clifford became a “more thoroughgoing evolutionary naturalist than either Huxley or Tyndall, as well as many others amongst the older generation who founded the X-Club.” Robert W. Smith’s essay, “The ‘Great Plan of the Visible Universe,'” looks at astronomer Huggins who, although rejecting traditional natural theology, sought a conception of the unity of nature founded upon divine design. A leading pioneer in the development of astrophysics, Huggins’ work, according to Smith, was shaped by deep “religious sensibilities.” However, this was only the Huggins of the mid-1860s. This early Huggins “saw very powerful evidence of design when he viewed the heavens.” Yet by the 1880s and 1890s, Huggins’ opinions had decidedly shifted to something more resembling Turner’s “Scientific Naturalist.” Unfortunately, why this shift occurred, says Smith, is rather obscure. Jonathan Smith, in the final essay in this section, “Alfred Newton: The Scientific Naturalist Who Wasn’t,” shows how Newton applied Darwinism to his own work in ornithology, but was “restrained and cautious in his public endorsement of Darwinism.” Indeed, he did not “share the broader agenda of scientific naturalism.” Newton was a clear example that “one could be a Darwinian without being a scientific naturalist.”

Part III, “Communicating Science,” looks at the disparate “modes of communication, including public lectures, scientific meetings, personal correspondence, newspaper editorials, pamphlets, and even town-hall meetings and church gatherings” that supported science during the Victorian period. Janet Brown, in the opening essay, “Corresponding Naturalists,”offers an engaging “correspondence-history” of the scientific naturalists, and “how epistolary exchange helped shape the very foundation of modern science, with its emphasis on evaluation, adjudication, authentication, prioritization and distribution of the latest scientific research” (my emphasis). In the same vein, Melinda Baldwin’s essay, “Tyndall and Stokes,” offers a more detailed examination of the epistolary exchange between Tyndall and mathematician and theologian George Gabriel Stokes. Although Tyndall and Strokes “differed radically in upbringing, temperament and religious orientation,” these ideological differences did not prevent them from maintaining a friendship, thus problematizing the notion of an antagonism between science and religion at the time. Baldwin demonstrates the central role their correspondence played in shaping the physical sciences in the Victorian period. The Tyndall Correspondence Project has found some two hundreds letters between Tyndall and Stokes, and it seems that Stokes, Baldwin suggests, “shaped both Tyndall’s papers and Tyndall’s idea about scientific theories.” In other words, Tyndall respected Stokes’ scientific expertise, consulted him on scientific theories, and even called on him to review some of his essays. Stokes was a member of the North British physicists, which have been portrayed as the great antagonists of the scientific naturalists. But the Tyndall-Stokes correspondence suggests a more complex picture. Bernie Lightman concludes with an essay on the “Science at the Metaphysical Society.” Much of what he has to say here depends on the research of Alan Willard Brown’s masterful The Metaphysical Society: Victorian Minds in Crisis, 1869-1880 (1947), but Lightman distinguishes himself from Brown’s politically idealistic philosophy. Most importantly, Lightman shows that religious members of the Society were not anti-science; rather, “they simply had their own definition of what it was, the role it should play in society, and the broader ramifications of its findings.”

This set of essays, along with those in Victorian Scientific Naturalism (2014) complicates our conventional understanding of Victorian naturalists. “The contest for cultural authority,” Lightman concludes in The Age of Scientific Naturalism, “was not only between the Anglican clergy and scientific naturalists. Feminists, socialists and others were claiming that they were qualified to provide leadership, and that contemporary science supported their claims.” Furthermore, the scientific naturalists were not mere “agnostics,” in the contemporary sense of the term, as “rationalists.” Their ideas, and ideals, were infused with metaphysics, a romantic sense of nature, and, indeed, a deep reforming spirit, of knowledge, society, and religion.

Victorian Scientific Naturalism

A numDawson and Lightman - Victorian Scientific Naturalismber of books of recent date have made significant contributions to our understanding of the Victorian coterie known as the scientific naturalists. A comprehensive survey of the last few decades of scholarship in this field can be found in Gowan Dawson and Bernard Lightman’s introduction to their Victorian Scientific Naturalism: Community, Identity, Continuity (2014). Dedicated to Frank Miller Turner, who was one of the first scholars to use “scientific naturalism” as a historiographic category to describe a group of Victorian intellectuals—such as, e.g., Charles Darwin, Herbert Spencer, Thomas Henry Huxley, John Tyndall, William Kingdon Clifford, Francis Galton, Karl Pearson, John Lubbock, Edward Tylor, George H. Lewes, E. Ray Lankester, Henry Maudsley, Frederic Harrison, Leslie Stephen, John Morley, Grant Allen, and Edward Clodd—with the supposed common goal of redefining nature, humanity, society, and science, Dawson and Lightman have collected a group of essays first presented at a workshop on “Revisiting Evolutionary Naturalism: New Perspectives on Victorian Science and Culture” at York University in 2011.

They begin their introduction with an etymological survey of “scientific naturalism,” showing that long before Huxley used it in his Essays upon Some Controverted Questions (1892), it was employed by American evangelicals in the 1840s as a pejorative epithet. In the 1860s and 70s,  Scottish Free Church theologian David Brown and journalist and owner of the Contemporary Review William Brightly Rands also complained that scientific naturalism was the cause of “an inescapable sense of melancholy” and “moral decay” of their time. Only at the turn of the decade, in a letter published in the Secular Review, scientific naturalism was used, seemingly for the first time, as an “entirely positive designation for the scientific rejection of all nonmaterial phenomena.”

Returning to Huxley, Dawson and Lightman highlight his attempt to give the term a lengthy intellectual lineage. More interesting, however, is Huxley’s claim that the Bible is “the most democratic book in the world,” and that its strength lies in its “ethical sense,” and as such the “human race is not yet, possibly may never be, in a position to dispense with it.” In short, Huxley’s strategy was to make scientific naturalism “unimpeachably respectable, scrupulously cleansed of all the deleterious ethical and political connotations it had accrued since first coming into usage in the 1840s.”

Indeed, Huxley’s usage matched earlier connotations of the scientific naturalist, which simply meant being an expert and specialist practitioner of the life sciences. This leads Dawson and Lightman to suggest that scientific naturalism and scientific naturalist were “actor’s categories for much of the nineteenth century,” polemical constructs “employed by both evangelicals and secularists even before it was taken up by the archpolemicist Huxley.”

Dawson and Lightman then turn to twentieth and twenty-first developments. The work of Frank Turner is of course mentioned. But they also point out Robert M. Young’s collection of essays in Darwin’s Metaphor: Nature’s Place in Victorian Culture (1985), where an overarching theme of continuity is pronounced, “pointing out that while natural theology was built on an explicitly theological theodicy, scientific naturalism similarly rested on a secular theodicy based on biological conceptions and the assumptions of the uniformity of nature.” Two years later Lightman published his The Origins of Agnosticism (1987), which argued that “there were many vestiges of traditional religious thought embedded in Victorian agnosticism” and the “possibility that agnositicism originated in a religious context.” They also mention the influential work of Ruth Barton, especially her essays on the X-Club, John Tyndall, and the origins of the scientific journal, Nature.

More recently, historians of science have begun marginalizing Turner’s notion of an emerging, professional scientific elite. Adrian Desmond’s The Politics of Evolution (1989), Ann Secord’s “Science in the Pub” (1994), James Secord’s Victorian Sensation (2000), John van Wyhe’s Phrenology and the Origins of Victorian Scientific Naturalism (2004), and Lightman’s Victorian Popularizers of Science (2007), pushed “back the establishment of a secular naturalistic tendency in British science into the 1830s and 1840s,” essentially placing the scientific naturalists on the periphery. We should add here Lightman’s own collection of essays on Evolutionary Naturalism in Victorian Britain (2009), which examined the enduring strength of religion in the late nineteenth century and the vestiges of religious thought among the scientific naturalists, the problems of communicating their message to the general public, and Victorian critics of scientific naturalism and their strong resemblance to postmodern criticism.

Despite being pushed to the periphery in modern scholarship, Huxley and the scientific naturalists continue to fascinate. Paul White’s Thomas Huxley: Making the ‘Man of Science’ (2003) demonstrates that Huxley’s self-identity was “drawn, in part, from his understanding of domesticity, literature, and religion.” Dawson‘s own Darwin, Literature, and Victorian Respectability (2007) shows how advocates of scientific naturalism constructed “their model of professional scientific authority in line with their opponents’ standards of respectability.” Here again we should also add Lightman and Machael S. Reidy’s The Age of Scientific Naturalism (2014), which focuses on physicist John Tyndall, but also contains exemplary essays on Herbert Spencer and the metaphysical roots of his evolutionary naturalism, William Clifford’s use of Spencerian evolution, and many others.

“The time is right,” writes Dawson and Lightman, “to return to those canonical figures, in the light of the new scholarly agendas, and reevaluate their status as icons of the Victorian scientific scene.” With a focus on “forging friendships,” “institutional politics,” “broader alliances,” and “new generations,” this volume of essays offers “new perspectives on Victorian scientific naturalism that…produce a radically different understanding of the movement centering on the issues of community, identity, and continuity.”
