I cannot live without brain-work. What else is there to live for? Stand at the window here. Was ever such a dreary, dismal, unprofitable world? See how the yellow fog swirls down the street and drifts across the dun-coloured houses. What could be more hopelessly prosaic and material? What is the use of having powers, doctor, when one has no field upon which to exert them? Crime is commonplace, existence is commonplace, and no qualities save those which are commonplace have any function upon earth.
Arthur Conan Doyle (1859-1930) British writer and physician

The original publication, and Doyle's manuscript (along with many other iterations across media) use "The Sign of the Four" as the title, while others (including the first book publications) use "The Sign of Four." The five-word form is used most commonly in the story, but the four-word form does show up. (More info.)
Published in novel form as The Sign of Four (1890-10).

It was easier to know it than to explain why I know it. If you were asked to prove that two and two made four, you might find some difficulty, and yet you are quite sure of the fact.

He sat down and thought, in the most thoughtful way he could think. Then he fitted his paw into one of the Tracks … and then he scratched his nose twice, and stood up.

To be lost in thought is not to be idle. There is visible work and invisible work. To contemplate is to toil, to think is to do.

Ideas come when we do not expect them, and not when we are brooding and searching at our desks. Yet ideas would certainly not come to mind had we not brooded at our desks and searched for answers with passionate devotion.

- "Ideas come when they are least expected, rather than while you are racking your brains at your desk. But, by the same token, they would not have made their appearance if we had not spent many hours pondering at our desks or brooding passionately over the problems facing us." [tr. Livingstone]
- "[Ideas] come, at any rate, when one does not expect them, not while racking one's brains and pondering at one's desk. Of course, the ideas would not have occurred to us without our having been through the state of racking our brains and being engaged in impassioned questioning." [tr. Wells (2018)]

Observe the invincible tendency of the mind to unify. It is a law of our constitution that we should not contemplate things apart without the effort to arrange them in order with known facts and ascribe them to the same law.
