"I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it - there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones."

A Study in Scarlet
by
Sir Arthur Conan Doyle
What can we know? What are we all? Poor silly half-brained things peering out at the infinite, with the aspirations of angels and the instincts of beasts.

The Stark Munro Letters
by
Sir Arthur Conan Doyle
Are you conscious of the restful influence which the stars exert? To me they are the most soothing things in Nature. I am proud to say that I don't know the name of one of them. The glamour and romance would pass away from them if they were all classified and ticketed in one's brain. But when a man is hot and flurried, and full of his own little ruffled dignities and infinitesimal misfortunes, then a star bath is the finest thing in the world.

It is decreed by a merciful Nature that the human brain cannot think of two things simultaneously.

The Lost World

Sir Arthur Conan Doyle
"I remember a mass of things, but nothing distinctly; a quarrel, but nothing wherefore. O God, that men should put an enemy in their mouths to steal away their brains!"

Othello
by
William Shakespeare
A hound it was, an enormous coal-black hound, but not such a hound as mortal eyes have ever seen. Fire burst from its open mouth, its eyes glowed with a smouldering glare, its muzzle and hackles and dewlap were outlined in flickering flame. Never in the delirious dream of a disordered brain could anything more savage, more appalling, more hellish be conceived than that dark form and savage face which broke upon us out of the wall of fog.

Sir Arthur Conan Doyle
"I think I should have no other mortal wants, if I could always have plenty of music. It seems to infuse strength into my limbs, and ideas into my brain. Life seems to go on without effort, when I am filled with music."
