Older, but no wiser

Found this over at Parking Lot. As Chris says:

"A brilliantly rendered story of the four quadrants of integral theory. This map is just so helpful in looking at so many situations. This particular presentation is a lovely use of web technology as well."

(Don't let the word 'theory' put you off from clicking on the link: that's integral as in whole, i.e. holistic, not integral as in calculus...)
