Today, the assertion that ‘the brain is the organ of mind’ is treated as an almost self-evident scientific truth. Yet, as Elfed Huw Price demonstrates in his meticulous and expansive study, this identification was far from a foregone conclusion two centuries ago. In William Lawrence and the Organ of Mind, Price resurrects the embattled legacy of Sir William Lawrence, a man whose nineteenth-century lectures on physiology were once deemed so dangerous they were legally stripped of copyright protection. Price argues that our modern understanding of the material mind owes a debt to this Georgian radical, whose career serves as a lightning rod for the era’s anxieties regarding the relationship between the corporeal body and the immortal soul. Price’s central thesis is that Lawrence represents a dogmatic shift in a 2,000-year-old debate. To understand the impact of Lawrence’s lectures, one must first understand the narrative he was dismantling. For centuries, the western map of the mind was a fragmented and often a non-corporeal affair.
Price expertly traces the long lineage of thought that Lawrence eventually upended. He reminds us that for the earliest scholars, the brain was rarely the undisputed ‘seat’ of thought. Aristotle, famously, was a ‘cardiocentrist,’ viewing the heart as the seat of intelligence—thus, the poetic description of our heart aching when we feel melancholy—and the brain merely as a cooling mechanism for the blood. While Galen later shifted the focus to the brain in the second century, he did so through the lens of ‘animal spirits’ flowing through ventricles, the fluid filled cavities in the brain as we understand today, a theory that preserved a gap between the physical tissue and the ‘rational soul’ (25). By the seventeenth century, Rene Descartes had codified this gap into his dualism. For Descartes, the mind (res cogitans, the ‘thinking thing’) was an immaterial substance that interacted with the body (res extensa, the ‘extended thing’) via the pineal gland (27). Even William Harvey’s revolutionary discovery of the circulation of the blood in 1628, while mechanistic, did not fully ‘embrain’ the mind; it focused on the ‘sun of the body’ (the heart) rather than the ‘organ of thought.’
One of the book’s most compelling contributions is its analysis of why Lawrence’s views were perceived as such an existential threat to regency England. During the eighteenth century England functioned as a confessional state where adherence to Anglican doctrines, specifically the immortality of the soul and the Holy Trinity, was a cornerstone of political authority and divine right. Lawrence’s materialism was seen as a harbinger of atheism and democracy, tainted by association with the ‘bloody and chaotic’ French Revolution. If the mind were simply a function of ‘medullary’ matter, as Lawrence proposed, then the death of the brain implied the annihilation of the self, thereby undermining the religious and moral sanctions that governed society. Price recovers the voices of critics like George D’Oyly and Thomas Rennell, who argued that Lawrence’s ‘zoological stance’ threatened the very distinction between humans and beasts.
One of the most significant contributions of this work is Price’s refusal to treat this as a mere ‘science vs. religion’ conflict. Instead, he explores the complex ‘theology of the brain’. He situated Lawrence within a tradition of dissenting thought and Christian ‘mortalism’— the belief that the soul sleeps or dies with the body until the resurrection. By tracing the influence of Joseph Priestley and the Unitarian tradition, Price shows that the material mind was not an invention of secularism, but a concept rooted in heterodox theology, i.e., God gave matter the capacity to think. The book brilliantly illustrates how the brain became a site where Trinitarian debates, anatomical dissection, and political reform intersected. For Lawrence, to understand the brain was to understand the ‘natural history of man,’ a project that necessarily challenged the hierarchical and divine-right models of human existence favored by the conservative establishment.
The closing chapters trace the rapid acceptance of Lawrence’s ideas. By the mid-nineteenth century, what was once generally shuddered at had become universally accepted. This shift coincided with the political reforms of the 1830s, including the Reform Act and the Anatomy Act, which redrew the boundaries of society and decentralized the church’s authority. While he concludes, Price reflects on our current state of confusion about the brain. While we have largely ‘black-boxed’ the mind inside the head for philosophical convenience, to this day, we remain unable to explain how matter produces consciousness. He aligns himself with modern scholars who view the mind as an embodied and distributed process rather than a purely ‘embrained’ one.
William Lawrence and the Organ of Mind is a rich, interdisciplinary work that will be of immense value to historians of science, literature, and medicine. Price’s work is accessible yet rigorous, effectively using Lawrence’s life to bring to light a pivotal moment in the history of human identity. By challenging the tyranny of labels and investigating the stumbling blocks of the past, Price invites us to reconsider why we think the way we do about the three pounds of matter inside our skulls. This book is an essential case study of how the ‘airy regions of immaterial being’ (81) were eventually grounded in the anatomical reality of a nineteenth-century clinic.
