Allow me to introduce myself to you as an advocate of Ornamental Knowledge.  You like the mind to be a neat machine, equipped to work efficiently, if narrowly, and with no extra bits or useless parts.  I like the mind to be a dustbin of scraps of brilliant fabric, odd gems, worthless but fascinating curiosities, tinsel, quaint bits of carving, and a reasonable amount of healthy dirt.  Shake the machine and it goes out of order, shake the dustbin and it adjusts itself beautifully to its new position.
