Ratiocination versus The Age of Reason
14 December 2025 Leave a comment
Although Edgar Allan Poe is most famous for his poetry and tales of the macabre, as an author he was so much more than that. The horror tales and poetry are but a tiny portion of a body of work extending to criticism of current events, literature, art, architecture and design; satire; historical fiction; proto-science fiction; travel narratives; and even serious mathematical[1] and scientific investigation[2].
He is, with justification, often cited as the creator of the modern detective story. His three tales featuring Auguste Dupin introduced the concept of the amateur investigator and an approach to solving mysteries (he called it “ratiocination”) that influenced nearly every writer of detective fiction since. But is there more going on here? His mysteries, and not just the Dupin stories, can also be viewed as explorations of the limits of the intellectual and scientific ideals of the Age of Reason and its dogma that reality can be fully explained purely through scientific observation and the application of human reason.
From a blog post on the Dupin stories, I found some interesting analysis, quoted from Murray Ellison’s Masters Thesis on “Poe and 19th-Century Science” (Virginia Commonwealth University, 2015). I would love to find that document to read it in its entirety, but the blog quotes it extensively, as I will also do here.
“A ratio compares the relationships between two quantities. Poe develops a new system for establishing relationships between unknown events and the motives or solutions to complex problems. Dupin expands the use of accepted nineteenth-century classical investigation techniques and adds hyper-observation and intuitive leaps of imagination to arrive at new solutions. He understands that clues and events are not always understood simply by the way that they appear.”
In his Dupin stories the formal investigative authorities represent the Enlightenment voice. Their failure to solve the crimes (which Dupin does, often from his armchair) demonstrates the limitations of their approach.
“With the same understanding of the evidence that the police hold, he provides new metaphoric solutions. His methods of unraveling crimes are unorthodox and appear to the police as irrational. Dupin presents the details of these cases directly or through an unnamed narrator to give readers a glimpse into his ratiocinative thinking … Dupin separates the relevant from the irrelevant. He focuses on unexplained deviations from the normal, anticipates the actions and thoughts of his associates and opponents, and embraces information that, at first, appears to be external to the case.”
“As a non-professional detective, Dupin mocks the inferior crime-solving techniques of the paid Parisian police officials. The prefect appears in each of the Dupin stories and … thinks he has the perfect solution to the crime. However, Dupin is always skeptical of his approach and solutions.”
“The police are symbols for his criticisms of the professional scientists of the nineteenth century.”
Poe set the Dupin stories in Paris.
“Perhaps, he … made this choice because many French scientists and philosophers [of Poe’s time] epitomized Poe’s criticisms of these intellectual ideas of the nineteenth-century Age of Reason[3]. They rejected dogma and sought ways to find objective knowledge. They believed that truth could be best be verified by observation and scientific investigation. Among the ideas that Poe attacked in his detective stories was the irrational belief that man could ultimately attain near stages of perfection, and that he could control his environment [entirely] by scientific methods. Because of these contradictory views, it is hard to determine if Poe proposed ratiocination to address crime, or if he was mocking the irrational faith that the Age of Reason thinkers had in science.”
No one familiar with the vast range of Poe’s corpus of work would make the mistake of concluding that he was opposed to science and reason. His scientific writing is notably rational and often prescient. He even often used fiction to expose scientific hoaxes of his day and to provide well-reasoned explanations of the actual, scientific truth.
“In his three tales of ratiocination, Poe demonstrates that Dupin’s methods of scientific reasoning are superior to those of the police. He is critical of the established authorities and power structures. … He believes that scientists [of his time] are limited in arriving at new solutions in the same ways that the police are limited in solving crimes.”
So, his view seems to be that while science and reason are critical, science and reason alone are insufficient. It takes a spark of genius that goes beyond mere observation and reason. Poe isn’t anti-science or anti-reason. He merely seems to have viewed that too absolute a reliance on the science of his day leaves important variables out of the equation.
Science has advanced mightily since the mid-19th century. The fruits of scientific observation and reasoning are accumulative and provide a far sturdier foundation for what is demonstrably knowable to work from, making it easier to avoid any shortcomings of the past. Perhaps his views are relevant only to a critique of the limited state that science had reached in his own day.
But one wonders what Poe would make of the state (and limits) of scientific advancement achieved today. And what hobby horses of hubris and limited thought would be the target of his critical skewers?

[1] Among his earliest paid journalism was a cryptography challenge, boasting that he could break any coded message submitted by the paper’s readers. “He received nearly a hundred secret messages from all over the country. Poe solved them all, except for one. And that coded message he proved to be ‘an imposition,’ a jumble of ‘random characters having no meaning whatever.’” (A Love of Mystery Is Woven into our Biology, and Edgar Allan Poe was the First to Find the Formula for a Very Specific Dopamine Hit.)
[2] Poe’s “Eureka” (1848) posits that the universe began from a singular, unified state and expanded over time, long before the formal development of the Big Bang model. Later scientific discoveries moot nearly all the details. He got “what happened” wrong, but some of Poe’s concepts align surprisingly well with modern cosmology.
[3] There is an alternative possibility. The source article also observes that Matthew Pearl, in his “Introduction” to the Dupin Mysteries, notes that “Poe introduced Detective C. Auguste Dupin, of Paris, France to literature more than five years before Boston had established the [United States’] first professional police department.”



But when you send your child to school, who checked to ensure that the engineering of the utility services was done correctly? In 1937, an explosion at a school in New London, Texas, killed 300 people and severely injured another 300, many of them children. (Some estimates place the casualties as high as 1,000.) The cause of the explosion? Faulty engineering linked to cost saving actions taken by the school board. This tragedy was one of the motivating forces behind passage of Texas’ licensure law that same year.


As NSPE ends one fiscal/program year and starts a new one, it would be typical to talk about the past year’s activity. That is worth doing: we have a good story to tell, and NSPE’s accomplishments of 2016-17 are something we can all take pride in. But that would be repeating a story that you have already been told, as it was happening.
At a recent conference, I was diligent in my efforts to use social media to not only capture my own notes, but share them with my colleagues and associates, present and absent. I got a decent amount of reaction and interaction for my efforts. Retweets, likes, comments and discussion. (Nothing remotely viral, mind you, but my efforts did not go unnoticed by the (in the grand scheme of the world) relatively small community of professionals who share my interests and concerns.)
Collins calls Level 5 leadership: “the paradoxical blend of personal humility and [fierce] professional will.” You need to be able to take your own ego-gratification out of the equation when assessing the association’s strategic needs, but also refuse to make allowances for any limitations that might be present on your board by compromising on the level of leadership their role demands from them. You need to be authentic in giving the board credit for association success and in truly owning any board failure as your own. And never, never, never, letting a setback cause you to doubt yourself or become tentative and risk averse. Take the hit, learn what you can from it, turn the page, and move on. In doing so, you become not only something of a safety net for the board, making it less risky for them to take bold action. You also model the behavior that will enable them to be effective in their own leadership roles.
