"When our thoughts revolve we are so often deceived into supposing that their violent movement is an indication of their vigorous originality, the upheaval of prejudice and fixed ideas, when all the time it is more likely that the machine which contains them is only an elaborate cement-mixer, and when the thinking is finished, those whirling thoughts are smoothed into the unchanged conventional mould and seeing them set solid enough to dance, to build, to travel upon, we would never dream of their first deceit, of the hope once roused by their apparently violent reorganisation."
