A really interesting post from Daniel Hartley on the Fall here: http://thinkingblueguitars.wordpress.com/2011/01/12/o-happy-fall/
He writes that the Fall had three modes: 1) practical - 'it was good for food'; 2) aesthetic - 'it was pleasant to the eyes'; 3) epistemological - 'a tree to be desired to make one wise.' It reminds me of Kant's division of human faculties, reason (wisdom), understanding (knowledge), and judgement (beauty). I'd never seen the Fall described in that way before. Interesting that Eve encountered temptation in all three modes.
