Sherlock Holmes is one of the most iconic fictional detectives, having gotten his start with Arthur Conan Doyle’s books, and in more modern times, starring in numerous film adaptations. He is best known for his impressive deduction skills.
Writers love quoting Sherlock Holmes, especially in news articles, which proves the timeless quality of the books.
15 Most Memorable Sherlock Holmes Quotes
If you love Sherlock Holmes, these quotes may bring back fond memories from some of your favorite scenes.
“You see, but you do not observe.”
Sherlock Holmes says this line in A Scandal in Bohemia, giving us a clear picture of what makes him a very good detective: his keen observation skills!
“Elementary, my dear Watson.”
This line is perhaps one of the most quoted Holmes lines, used even by those who have never read any of the mystery novels.
This is also the line most frequently used in film adaptations, whenever Holmes finds some detail that Watson may have missed—but it’s never actually used in any of the books!
For the record, the actual quote in the book The Memoirs of Sherlock Holmes actually goes,
“I have the advantage of knowing your habits, my dear Watson,” said he. “When your round is a short one you walk, and when it is a long one you use a hansom. As I perceive that your boots, although used, are by no means dirty, I cannot doubt that you are at present busy enough to justify the hansom.”
“Excellent!” I cried.
“Elementary,” said he. “It is one of those instances where the reasoner can produce an effect which seems remarkable to his neighbour, because the latter has missed the one little point which is the basis of the deduction.
“It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.”
This quote from A Scandal in Bohemia again reminds us of a very basic principle in Holmes’ mystery-solving strategy, which is not to theorize before getting the facts complete. In fact, he also gives an important clue to the common failings of other detectives.
“You know my methods, Watson.”
This is one of the most common lines that Holmes uses, almost identically, in at least five novels. This gives us a feel for the close relationship between Holmes and Watson, and how accustomed Watson has become to his ways of solving a mystery.
“To a great mind, nothing is little. “
Arthur Conan Doyle gives us this very memorable quote in the very first Sherlock Holmes novel, A Study in Scarlet, giving us an idea of how much value Holmes places in the minutest detail—a classic characteristic that fans have come to associate with the beloved detective.
“My name is Sherlock Holmes. It is my business to know what other people do not know.”
This is Holmes’ very interesting introduction in The Adventure of the Blue Carbuncle, and it sums up exactly what his task is in the numerous mysteries thrown his way.
“Dear God. What is it like in your funny little brains? It must be so boring.”
This line, delivered by Benedict Cumberbatch, is from the Sherlock BBC Series, and it gives us a very realistic portrayal of the fictional detective we know and love: how must it feel for somebody with such keen observation skills to deal with everyone else who doesn’t have half his abilities?
“The devil’s due a soul, I’d say.”
In the 2009 film adaptation, Robert Downey Jr. plays a very convincing Sherlock Holmes, complete with the skillful use of understatements, such as this line. The paradox is that Holmes is not in the least superstitious, but he plays along what the people in the movie believe about the enemy.
“I abhor the dull routine of existence. I crave for mental exaltation. That is why I have chosen my own particular profession, or rather created it, for I am the only one in the world.”
We’re given this line from The Sign of the Four, which effectively describes the boredom Holmes experiences whenever he finishes a case, which inevitably propels him into the next one.
“How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?
In The Sign of the Four, we find another principle that Holmes holds to firmly: something that seems improbable can still be the truth in the case he’s working on.
“…the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beautiful countryside.“
In The Adventures of Sherlock Holmes, Watson expresses surprise at the connection of crime with “these dear old homesteads.” But Holmes is quick to show Watson the fault in his reasoning, based on his own experience.
“Where there is no imagination, there is no horror.”
In A Study in Scarlet, we get this profound insight into what makes things horrifying, but on the other hand, what also makes mysteries so exciting: the power of our imagination!
“But love is an emotional thing, and whatever is emotional is opposed to that true cold reason which I place above all things.”
When Holmes discovers that Watson and Mary Morstan are engaged, he doesn’t congratulate them, and instead makes this statement expressing his devotion to logic over love. The 2009 film starring Robert Downey Jr. effectively portrays Holmes’ aversion to the engagement, albeit in an underhanded way.
“Life is infinitely stranger than anything which the mind of man could invent.”
The short story “A Case of Identity” begins with this line, taking an insightful look at the oddities of the human existence. This unpredictability is likely what draws Holmes to solving mysteries from the very start.
“Never trust to general impressions, my boy, but concentrate yourself upon details.”
This quote from “A Case of Identity” gives us another glimpse of Holmes’ commitment to examining every little detail, stated as one of his many attempts to train Watson in his ways.
