Aromatics and the Soul: A Study of Smells
Dan McKenzie (1870–1935)
The sense of smell is our most neglected and mysterious faculty, an invisible bridge between the physical world and the deepest recesses of the human soul. This exploration reveals how scent governs memory, emotion, and our subconscious lives.
In Short
This work is a wide-ranging, inquisitive examination of the human olfactory sense. It bridges the gap between medical science and the humanities, investigating why our sense of smell is so powerful yet so difficult to articulate. By analyzing the physics of odor, the history of perfumery, and the peculiar ways scents trigger vivid, involuntary memories, the book argues that olfaction remains our most intimate, albeit undervalued, connection to reality. Its enduring relevance lies in its graceful, witty defense of a sense that modern life—and modern language—often tries to ignore.
The Story
The narrative begins with a confession: the author, a medical professional, has intentionally omitted a specific anatomical structure—Jacobson’s organ—from his main text, only to address it in the preface with the playful temperament of an artist. From this spirited opening, the book launches into a broader investigation of how civilization has dulled our olfactory acuity. The author observes, through his own travels in cities like Lucerne, that modern urban dwellers have become "anosmic" to the stench of their own surroundings, trading a heightened sensitivity for the perceived comforts of progress.
As the argument deepens, the focus shifts to the strange, often jarring relationship between smell and the social order. The author explores how England’s unique obsession with "fresh air" and the national bath helped wage a war against public stenches, effectively cleaning up the environment while simultaneously rendering the populace more sensitive to the occasional, lingering foulness. This leads to a fascinating look at the animal kingdom, where the author recounts the clever use of bluebottle flies by a London plumber to locate a hidden, rotting drain—a testament to the olfactory precision of insects that humans have largely lost.
The middle arc of the book concerns the "speechless" nature of smell. Unlike sight or hearing, which are supported by vast vocabularies, smell lacks a terminology of its own. We are forced to rely on analogies—"smelling like" this or that—which leaves our olfactory experiences largely trapped in the subconscious. This gap is bridged only by the power of memory. The author shares poignant, personal anecdotes of childhood—the smell of a gardener’s bonfire or the scent of pine—to show how odors can instantly transport a person back to a forgotten moment, vibrating the soul with a force that visual or auditory images cannot replicate.
In the final movement, the book reconciles these sensory mysteries with physical theory. The author navigates the complex debate between chemical and physical explanations of odor, including the fascinating, if controversial, idea that smell might function through "ethereal waves" similar to light. The narrative concludes with a reflection on how cities, nature, and even religious rites are defined by their unique atmospheres. By the end, the reader is left with the understanding that while we may be "microsmatic" compared to moths or dogs, our capacity for olfactory wonder remains vast and inexhaustible, waiting only for us to pay attention.
How It Unfolds
The gate of the pagoda The author sets the tone by discussing the importance of small details, comparing his writing process to a sculptor removing marble to reveal a masterpiece. He establishes the premise that a scientific writer can and should possess the sensibility of an artist.
The desensitized citizen Through observations of European cities and the "stinking" realities of wartime, the author posits that town life blunts the nose. He suggests that by constantly avoiding foul odors, we cultivate a fragility that makes us unable to tolerate even minor olfactory disturbances.
The detective work of nature The author turns to the animal kingdom to demonstrate the utility of scent, detailing a plumber’s use of flies to find a hidden drain. This provides a clear, practical example of how the olfactory sense functions as a sophisticated, biological GPS.
The silence of the nose A central crisis of the book is the lack of language for scent, which the author contrasts with the descriptive richness of vision and sound. He examines why we are so limited in our ability to describe what we smell, characterizing the nose as a "speechless" organ.
The memory trigger Moving into the psychological, the author explores how smell bypasses the will to recall the past. He argues that odors provide an "olfactory aura" that can physically transport the subject into their own history more effectively than any other stimulus.
The physical mystery The final beats delve into the scientific theories of odor, weighing the merits of molecular contact against the "ethereal wave" theory. The book leaves these questions open, acknowledging that science has yet to fully explain the profound influence of scent on human life.
The People
The book is populated by a mix of historical figures, personal acquaintances, and scientific pioneers. Dr. V. H. Wyatt Wingrave is the dedicatee, a nod to the author’s professional community. Fabre, the naturalist, stands as a foil to the author; while the author respects Fabre’s skepticism regarding insect olfaction, he gently pushes back, noting that human senses are more capable than skeptics admit. Zwaardemaker represents the scientific rigor of the time, providing a systematic classification of odors that the author uses as a foil for his own, more intuitive observations. The author himself appears as a central, guiding presence—a physician, a traveler, and a man who is unapologetically subjective in his love for the "clean chill" of an English April day. His plumber acquaintance serves as a recurring, practical hero, illustrating that the common man often understands the utility of smell better than the academics. Finally, the "English school-ma’am" and the "fashionable lady" serve as archetypes of the modern, sensitive, and occasionally fastidious subjects whose reactions to odor provide the author with his most vivid sociological data.
In Its Own Voice
The author highlights the peculiar, involuntary way that scent interacts with our memory, contrasting it with the weakness of our own descriptive abilities.
"But if the recollection of a scene can only with difficulty, or not at all, revive the sensation of an odour, the converse is most startlingly true."
The author also notes the profound, universal nature of smell, which pays no attention to social standing or rank.
"Olfaction is thus the great leveller among the senses, equality having here a reality but rarely found elsewhere."
What It's Really About
The book is a meditation on the limits of human perception and the inadequacy of language to map our sensory lives. It argues that smell is the "backstairs" sense—a subtle, often ignored force that exerts a hidden, powerful influence over our emotional and intellectual states. Beneath the medical and scientific inquiries lies a deeper philosophical question: can we truly understand ourselves if we continue to ignore the one sense that acts most directly upon our deepest, most private consciousness? The author posits that by reclaiming our attention to the "ethereal" world of odor, we might rediscover a more authentic, vibrant way of experiencing the world, one that bridges the gap between the material and the spiritual.
Why Read It Today
Readers who enjoy the intersection of medical history, naturalism, and personal essay will find much to admire here. The prose is elegant and conversational, reminiscent of a time when a physician was expected to be a man of letters as well as a man of science. Reading this feels like walking through an old library with a witty, well-traveled, and slightly opinionated guide. You will encounter the author’s turn-of-the-century sensibilities—some of which may strike a modern reader as quaint or rooted in the class attitudes of the British Empire—but these moments only add to the book’s character as a historical document of the human mind. The length is substantial, but the structure is modular, allowing you to dwell on his musings about the "Castle of Indolence" or the "olfactory aura" of cathedrals at your own pace. You will walk away with a changed perspective on the mundane: the smell of a stable, the scent of a bonfire, or the "cold smell of a corpse from the Liffey" will no longer be mere background noise. Instead, they will become distinct, meaningful threads in the tapestry of your own life. This is a book for those who want to slow down and rediscover the world through a sense that has been waiting to be understood all along.
