“Sentiment is a chemical defect found in the losing side.”
— Sherlock Holmes BBC Sherlock, Series 2, Episode 1: A Scandal in Belgravia, 2012
About this quote
Meaning
The line is a piece of deliberate self-armor. Holmes frames feeling as a vulnerability, something that clouds judgment and leads to defeat, and positions himself as someone who has rationally eliminated it. The word "defect" is key: he is not saying sentiment is merely unhelpful but that it represents a flaw in an otherwise functional system. The line is confident and a little cruel, but the context in which it appears makes clear that Holmes is not as free of feeling as he wants to believe. It reads as both a conviction and a defense mechanism.
Context
The line appears in the first episode of the second series, an episode built around Irene Adler, a character specifically designed to challenge Holmes's claims of emotional detachment. The dynamic between Holmes and Adler in this adaptation explores what happens when someone equally intelligent plays on his blind spots. The episode ultimately suggests that Holmes's insistence on emotionlessness is itself a kind of sentiment, a story he tells himself that has its own emotional charge. The line lands differently by the end of the story than it does when he first speaks it.
About the author
This line is written for the BBC version of Sherlock Holmes, developed by Steven Moffat and Mark Gatiss as a contemporary reimagining of Arthur Conan Doyle's detective. The show frequently uses Holmes's stated philosophy of cold rationalism as a position the narrative then quietly dismantles. Benedict Cumberbatch played the role across four series, bringing a quality to moments like this one that allowed the arrogance and the underlying fragility to coexist convincingly.
“I am the most unpleasant, rude, ignorant, and all-round obnoxious arsehole that anyone could possibly have the misfortune to meet. I am dismissive of the virtuous, unaware of the beautiful, and uncomprehending in the face of the happy. So if I didn't understand I was being asked to be best man, it is because I never expected to be anybody's best friend.”

“The world is woven from billions of lives, every strand crossing every other. What we call premonition is just movement of the web. If you could attenuate to every strand of quivering data, the future would be entirely calculable, as inevitable as mathematics.”
