Guest guest Posted February 4, 2007 Report Share Posted February 4, 2007 " ANIMAL SPIRITS " THE MIND IN HISTORY 17th century Before it was understood that the nervous system was electrical in nature it was thought that strange little beasts called animal spirits infested our bodies and brains. Willis thought that 'animal spirits' ferment and chemically explode in the nervous system, and described the brain as 'garnished with uncertain meanders and cranking turnings and windings' in the spaces of which the 'animal spirits' flow without us knowing. <http://www.abc.net.au/rn/science/mind/s838420.htm> Quote Link to comment Share on other sites More sharing options...
