Sherlock Holmes and TOK?

TOK is the well-known acronym Theory of Knowledge. What does that mean? Does that mean that there is a theory on what should by known and how it should be learned? That point remains unclear to me and continues to puzzle me. Who better than I know what I would like to learn and retain?

This is the paradox every student has to face to get the diploma; accumulate a basic knowledge in a range of mandatory matters even if you have no affinity for the topic.

You have certainly watch the remake of Sherlock Holmes inspired from the Novels of Sir Conan Doyle in which Sherlock Holmes is depicted as an eccentric character with an ample knowledge in a wide range of topic and served by a strong and minute sense of observation. Besides that, Sir Conan Doyle depicts his main character as perfectly ignorant in literature, philosophy and politics. I like the theory he develops to explain paradox between exceptional knowledge and ignorance of Sherlock Holmes.

He says that ‘’brain is like a little empty attic, and you have to stock it with furniture as you choose. A fool takes all sorts that come across so that the knowledge which might be useful to him gets crowded out, so that he has difficulty in laying is hands upon it. Now the skilful workman is very careful as what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work. It is a mistake to think that little room has elastic walls and can be distend to any extend…It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones’’ - The complete Novels and Stories Sir Conan Doyle Vol1

What is the most important? I like Sherlock Holmes character as he appears as a strong and reliable figure. Too many people have the tendency to talk about topics they even don’t master, just to show up as a smart and interesting person.
