"A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber-room of his library, where he can get it if he wants it"
About this Quote
The subtext is sharper than self-help. Doyle is pushing back against a certain 19th-century ideal of the well-rounded gentleman-scholar, stuffed with classical trivia as a status signal. Holmes’s version of intelligence is instrumental, almost anti-romantic: learn what helps you see patterns, solve problems, act decisively. Everything else belongs in the “lumber-room,” a word that’s faintly contemptuous - not “archive” or “library,” but a place where neglected things go to gather dust.
Context matters: this line comes from the Holmes stories, where Watson is constantly startled by Holmes’s selective ignorance (famously, about the solar system). Doyle isn’t arguing for stupidity; he’s arguing for systems. Offload what you can to books so your working mind stays agile. It’s a blueprint for expertise: not knowing everything, but knowing what matters - and being able to retrieve the rest on demand. In an age of endless information, it reads less like quaint metaphor than proto-search-engine philosophy.
