Navigating the Boundless Deep: How Science Forged a Poet's Soul Amidst a Crisis of Belief
In the mid-19th century, as scientific understanding of the universe expanded at an unprecedented pace, a profound question emerged for society: how would these new revelations, often challenging long-held religious and philosophical tenets, shape human experience and artistic expression? This is the core inquiry explored in Richard Holmes’s forthcoming book, The Boundless Deep: Young Tennyson, Science and the Crisis of Belief, which offers a fresh perspective on the intellectual landscape that shaped Alfred Tennyson, 1st Baron Tennyson. Far from merely drawing inspiration from scientific discoveries, Tennyson grappled intimately with the implications of an ever-expanding, yet more vulnerable, cosmos, reflecting a widespread societal tension that still resonates today.
Beyond Poetic Metaphor: Tennyson's Scientific Immersion
The popular perception often holds that poets like Tennyson selectively incorporated scientific imagery to enrich their verse. However, Holmes’s work, as reviewed by Robert P Crease in Physics World, reveals a deeper, more personal engagement. Born in 1809, the same year as Charles Darwin, Tennyson matured in an era where science was fundamentally transforming ideas about reality. Holmes notes that the universe was perceived as "stranger and vaster than previously thought," but also "more vulnerable and paradoxically, more temporary," stripping away notions of "Biblical eternities."
As a teenager, Tennyson diligently observed the natural world, interspersing poetic verses with "careful observations of plants, birds, animals and other natural phenomena" in his notebooks. His early writings, like the query from the 14-year-old poet, "O suns and spheres and stars…are you realities or semblances?", betray a mind actively wrestling with the nature of existence itself, not just its aesthetic representation. This deep engagement continued into his time at the University of Cambridge, where he formed an "unbreakable bond" with Arthur H Hallam, sharing interests in nature, poetry, and science. Their 1833 "science week" in London, visiting sites like the London Zoo in Regent’s Park and the Gallery of Practical Science in Piccadilly, demonstrates a deliberate pursuit of scientific understanding, not just casual curiosity.
The Coining of "Scientist" and the Weight of Deep Time
It was during this period that Tennyson’s Cambridge tutor, William Whewell, coined the term "scientist," a semantic shift that underscored the growing professionalization and distinct identity of scientific inquiry. That same year saw the publication of numerous astronomy books, including one by Whewell himself, which introduced readers like Tennyson and Hallam to "newly discovered star systems" and "their growth over immense and previously inconceivable periods of time, and finally their slow but inevitable extinction." These concepts of "deep time and deep space" fundamentally altered the understanding of the material universe, challenging conventional timelines and human centrality.
This profound intellectual shift collided with Tennyson's personal life in a devastating way. In the autumn of 1833, at just age 22, Hallam died unexpectedly from a brain haemorrhage. This was, as Holmes describes, "the most traumatic event of Tennyson’s life, 'a particular extinction from which he never recovered'." Tennyson spent nearly two decades processing this grief, culminating in the publication of In Memoriam A H H in 1850. While many scholars, including the evolutionary biologist Stephen J Gould in his 1995 book Dinosaur in a Haystack, have cited lines like "Nature red in tooth and claw" as anticipating Darwinian evolution and offering solace, Holmes offers a more nuanced interpretation. He argues that Tennyson’s grief was not assuaged by science, but rather intensified by his awareness that scientific truths prevented him from finding comfort in traditional religious belief. The "death of an individual," Holmes writes, "counted for nothing within the vast and pitiless scale of geological death and extinction," leaving Tennyson in a "state of hovering, or trembling, between science and religion, between empirical evidence and traditional faith."
Limitations to Consider: Science, Grief, and Human Solace
While Holmes masterfully illuminates the scientific undercurrents in Tennyson’s life and work, it’s important to acknowledge the inherent limitations in interpreting such complex interplay. As Gould himself observed regarding In Memoriam, "Science cannot tell us why a man should die so young, or how a grieving lover should resolve his suffering." The meticulous scientific observations that informed Tennyson's worldview, while profound, offered no direct balm for his personal anguish. This highlights a crucial distinction: science can explain how the universe works, but it often falls short in addressing the why of human existence and suffering, leaving a space for art, philosophy, and faith to grapple with those questions.
Holmes’s work also shines a light on overlooked figures who shaped the scientific literacy of the era, such as Jane Marcet, whose books on physics and chemistry inspired not only Tennyson but also Charles Lyell and Michael Faraday. It's a striking historical detail that Marcet, despite her influence, could not be elected to the Royal Society until 1921 due to her gender, while her husband, a Swiss doctor, was admitted. Similarly, the polymath Mary Somerville, "one of the only six persons in England who understands Laplace," acquainted Tennyson with the full spectrum of hard sciences. These insights underscore that scientific knowledge, then as now, is deeply embedded within human society and its prevailing norms.
The Next Steps: Interdisciplinary Dialogue and Human Experience
The Boundless Deep promises to be a significant contribution, showing that science is not merely a collection of facts but a dynamic force that continuously reshapes our understanding of the world and our place within it. Holmes’s ability to identify the diverse intellectual influences on Tennyson, from mentors like Whewell to groundbreaking women like Marcet and Somerville, enriches our understanding of the interconnectedness of knowledge.
The book, published by William Collins in 2025, will be a substantial work at 448 pp, priced at £25.00 for the hardcover and £14.99 for the ebook. Its forthcoming release invites further interdisciplinary exploration into how scientific paradigms influence artistic creation, philosophical thought, and the human response to profound personal loss. Understanding this historical interplay remains crucial for navigating our own era, where scientific advancements continue to challenge and redefine our perceptions of reality, compelling us to reconcile empirical evidence with our deepest human experiences.
