Hang ideas! They are tramps, vagabonds, knocking at the back-door of your mind, each taking a little of your substance, each carrying away some crumb of that belief in a few simple notions you must cling to if you want to live decently and would like to die easy!
Joseph ConradDo not talk to me of Archimedes' lever. He was an absent-minded person with a mathematical imagination. Mathematics commands my respect, but I have no use for engines. Give me the right word and the right accent and I will move the world.
Joseph Conrad
