Decoding Robert Langdon

The brain plays a vital role in our bodies. It is one of the organs without which we could not live. In a nutshell, it can be described as the body’s central processing unit. It controls our critical functions, including our thought processes, motor skills, memory, and even our emotional responses. It functions as a control room that is essential in regulating and coordinating the other bodily senses. The importance of the brain cannot be overstated. It is no wonder that it is often described in superlatives, such as being the sexiest or the most complex part of the body. But if there is another superlative that perfectly captures its essence, it would be that it is also the most mysterious part of the body. Certainly, the brain is one of the most puzzling organs. Because of these complexities and mysteries, the brain has become an object of fascination for many scientists, especially those in the field of neuroscience. Its full potential is often the subject of studies and even extensive discourse.

Ironically, the more the brain is studied, the more mysterious it becomes. Despite major breakthroughs in the study of the brain and its functions, many answers remain elusive. Dreams, which are often connected to the brain’s functions, are also objects of fascination due to our limited understanding of them. Many have even posited that we are not fully utilizing our brains—that we are using only 10 percent of them. Countless attempts have been made to decipher the brain’s many codes, yet it continues to leave questions unanswered while generating even more. It is no surprise that the brain, the mind, and memory are frequent subjects of literary inquiry, prevalent across the vast literary landscape. Because of these enduring mysteries, it was only a matter of time before renowned semiotician and writer Dan Brown would dabble in this intriguing subject. Where there is intrigue, Brown’s literary imprint is sure to follow.

Indeed, the brain and its wonders serve as the centerpiece of the American writer’s latest literary thriller, The Secret of Secrets. The first Brown novel since Origin (2018), the book transports readers to yet another cosmopolitan city: Prague, the Czech capital. With previous works set in symbolism-laden cities such as Rome (Angels and Demons), Paris (The Da Vinci Code), Florence (Inferno), Washington, D.C. (The Lost Symbol), and Barcelona (Origin), Prague initially seems like an unusual choice. However, as the story unfolds, the decision begins to make sense. The city is home to the Golem, a clay giant rooted in Jewish tradition. Because of the Golem and the rich folklore surrounding it, Prague becomes a hotbed of symbols and hidden messages. It comes as no surprise that Dan Brown, a master of semiotics, would seize the opportunity to make the city the setting for the sixth Robert Langdon novel.

Far too many fear death and regard it as the worst disaster that can befall them: they know nothing of what they speak. Death comes as a dissolution from an exhausted body…Just as the body leaves the mother’s womb when it is mature in it, so also does the soul leave the body when it has come to perfection.

Dan Brown, The Secret of Secrets

Professor Robert Langdon is once again at the heart of the pulsating events unfolding in the Czech capital. As is typical of Brown’s work, the novel opens with a grisly crime scene. A mysterious figure, caked in mud and known as the Golem, tortures Dr. Brigita Gessner in her underground laboratory. Gessner is a renowned Czech neurologist. Under duress, she confesses to committing horrific acts on human test subjects alongside her team of scientists. The prologue closes with Gessner’s gruesome murder and the Golem’s vow of vengeance on behalf of an unnamed woman. The story then backpedals a few hours before Gessner’s death. Professor Langdon is in Prague to attend his girlfriend Katherine Solomon’s lecture at Prague Castle, which centers on her new book. The book aims to revolutionize noetic science, the study of consciousness, and the lecture was delivered at Gessner’s invitation.

After the lecture, Solomon is seized by a nightmare. She dreams of a woman wearing a spiked crown and black robes who warns of an explosion at their hotel. Langdon and Solomon dismiss it as mere imagination. However, the following morning, while jogging, Langdon witnesses a woman eerily matching Solomon’s dream—carrying a silver spear and exuding the stench of death—crossing the Charles Bridge. As vision turns into reality, Langdon panics, recalling the nightmare. He rushes back to the hotel in search of Solomon. When he cannot find her and believes disaster is imminent, he pulls the fire alarm to evacuate the building. As the line between dream and reality blurs, Langdon grapples with the possibility of precognition or manipulation. The hotel does not explode—or so it initially seems.

Langdon later learns that the police did, in fact, defuse a bomb at the hotel that morning. During a casual conversation, he shares details of Solomon’s dream with Captain Oldřich Janáček, unaware that this seemingly innocuous exchange will put him in danger. Langdon’s foreknowledge arouses the captain’s suspicion. A veteran with over four decades of experience, Janáček accuses Langdon and Solomon of staging the bombing. Langdon’s inability to rationalize his actions, coupled with Solomon’s disappearance, deepens the captain’s doubts. Too many coincidences leave little room for uncertainty. Janáček insinuates that the couple orchestrated the bombing as a publicity stunt for Solomon’s book, capitalizing on the public’s fascination with her supposed ability to foresee the future.

Meanwhile, both Langdon and the authorities are unable to locate Solomon. She was scheduled to meet Gessner at her laboratory, the Crucifix Bastion. This leads the captain to the underground facility, which he finds in disarray and abandoned. A series of brutal events enables Langdon to escape the authorities, rendering him a fugitive. One thing becomes clear: he must find Solomon—and quickly. In New York, editor Jonas Faukman discovers that Solomon’s manuscript and all related files have been erased from Penguin Random House’s servers just hours after submission in a sophisticated cyberattack. Simultaneously, operatives in London and Prague are activated to contain the unfolding events. Unbeknownst to Langdon and Solomon, they have become targets of a relentless hunt, pursued by forces they do not yet understand.

There’s no such thing as muscle memory. It’s an oxymoron. Muscles don’t have memory. In reality, when you practice, you’re fine-tuning your brain…gradually rewiring it to receive information more clearly and consistently from the universal consciousness so it can command your muscles to contract in a perfect pattern to perform a task in a certain way.

Dan Brown, The Secret of Secrets

In typical Brown fashion, the novel brims with suspense and trademark symbolism. Prague is riddled with codes that Langdon must decipher as the story progresses. At the center of the mystery is Gessner’s laboratory, secured by encrypted passcodes rooted in ancient Greek, Latin, and mathematical symbolism. A connoisseur of symbology, Langdon deciphers these codes, granting authorities access to the facility. His expertise proves crucial as he and Solomon race against time, navigating Prague’s hidden corners while solving increasingly complex riddles to reach concealed locations. Brown keeps readers on edge, drawing them into the thrill of decoding symbols. These elements underscore the intersection of language, numbers, and the human mind.

The novel draws connections between historical puzzles and modern encryption. Prague then emerges as a character in its own right, one that plays an integral role in the story. Rich in history, symbolism, and mystery, the city provides the perfect backdrop. Beneath this quaint city is the Threshold, a subterranean facility built in the ruins of a Soviet-era bomb shelter. It is operated by a secret group called In-Q-Tel. When Langdon and Solomon unlock its secret entrance, the story inevitably transforms from a mainly historical inquiry to a techno-thriller. In Threshold, Langdon and Solomon uncovered a sinister secret that shocked both of them. It was a secret that could redefine humanity’s understanding of life, death, and consciousness. It is a facility that is detached from morality.

These revelations are kept from the public’s knowledge. This fuels conspiracy, a familiar element in Brown’s body of work. This conspiracy examines a universal truth: the ethical conflict between the pursuit of knowledge for the betterment of humanity and the desire to control that knowledge. It comes as no surprise that governments, and even the CIA, are deeply involved in the running of the facility. This underscores the desire of dark and powerful forces to control knowledge for power and control. Even amongst these institutions, access to and knowledge of such information is often classified, restricted, and weaponized. Secrecy becomes a code in itself, and those who expose it frequently meet violent ends. The Threshold symbolizes dark forces that seek knowledge not to enlighten humanity but to dominate it.

The Threshold also serves as a timely metaphor. It encompasses Brown’s critique of the dangers of unmitigated technological advancement. Brown critiques our growing reliance on artificial intelligence. The novel draws the limits of AI technology, illustrating how it can be manipulated, outsmarted, or even fail. But it is not only artificial technology that the novel criticizes. The novel highlights our extensive and unhealthy usage of social media. In one scene, a couple takes selfies at one of Prague’s highest viewpoints, prompting Langdon to reflect on how experiences are increasingly performed for online validation rather than lived authentically. Brown underscores how our obsession with social media and social media engagements has kept us from genuine experiences and human connection.

Fear makes us selfish. The more we fear death, the more we cling to ourselves, our belongings, our safe spaces…to that which is familiar. We exhibit increased nationalism, racism, and religious intolerance. We flout authority, ignore social mores, steal from others to provide for ourselves, and become more materialistic. We even abandon our feelings of environmental responsibility because we sense the planet is a lost cause and we’re all doomed anyway.

Dan Brown, The Secret of Secrets

At its core, the novel interrogates the nature of consciousness. The forces at play seek not only to study but to control and liberate the human mind. While framed as a scientific inquiry, the narrative also explores Terror Management Theory—the idea that fear of death drives much of human behavior. This can be noted across different fields such as art and war. Solomon’s book offers a potential answer to this fear, hence it is considered dangerously powerful. She theorizes that low levels of gamma-aminobutyric acid (GABA) enable telepathy and remote viewing, and that a precipitous drop in GABA at death may reveal what lies beyond. This provocative idea unfolds within a fast-paced, day-long adventure.

The novel also touches on mental disabilities such as Asperger’s and autism. A character even suffered from dissociative identity disorder. The novel also played with the notion of the mind’s ability to foresee the future, or at least unlock its potential to do so. Nostradamus comes as a prevalent example. There was even a premise about our desire to know what the future holds. As Langdon surmises, “Knowing the future is a human obsession.” Understanding these potentials, however, can pose dangers, as Langdon and Solomon experienced. Still, the mind itself is another puzzle, brimming with symbolism waiting to be unlocked. It also Trauma and healing were also explored in the novel. It showed how the psyche fragments to survive.

Brown’s most ambitious literary undertaking to date, The Secret of Secrets delves into the enigmas of the brain and consciousness while guiding readers through historic Prague. The novel tackles questions of life, death, artificial intelligence, and social media, offering a multilayered and rewarding read. Brown critiques institutional power, government hypocrisy, and the intersection of science and religion. Ultimately, the story comes full circle with themes of forgiveness and redemption. While symbols and codes define Brown’s work, The Secret of Secrets points toward a deeper truth: the greatest mystery is not in decoding symbols, but in the mind’s ability to form genuine connections and confront the unknown. In a world obsessed with understanding what it means to live, these insights feel both urgent and timely.

We already know from near-death experiences that death involves a breaking free from our physical form…combined with an intense feeling of joy and connection to all things. If we know our individual consciousness comes from outside our brain—as so much noetic research now shows—then to my ear, it sounds like consciousness simply abandons the physical realm at the moment of death…and reintegrates back into the whole. You no longer need your body to receive the signal…you are the signal.

And the same holds true for many people with Asperger’s or autism. They can have highly specialized receivers that provide them access to remarkable skills and insights, and yet simultaneously make it difficult to perform routine tasks. It’s a bit like wearing binoculars instead of eyeglasses; you could see much farther than most … and yet your immediate surroundings would be blurry.
