It is not too much to say that when the Great War broke out our Generals had the most important lessons of their art to learn. Before they began they had much to unlearn. Their brains were cluttered with useless lumber, packed in every niche and corner.
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.Sir Arthur Conan Doyle
Processing the human raw material is naturally more complicated than processing lumber.maxim gorky
I saw within the wheelwright’s shedThe big round cartwheels, blue and red;A plough with blunted share;A blue tin jug; a broken chair;And paint in trial patchwork squareSlapping up against the wall;The lumber of the wheelwright’s trade,And tools on benches neatly laid,The brace, the adze, the awl;vita sackville-west
The bookful blockhead, ignorantly read, With loads of learned lumber in his head.Alexander Pope
"Let's face it: there are few things in this world more stupid than dancing. Except break dancing, which pirates and lumber jacks would agree is awesome. Other than that, dancing makes me envy cripples." "If women ran the world, we'd still be searching for the wheel."
