There are many dualities: mind/body (correlative: heaven/earth, social/individual-nature), moral/practical etc.
They all suffer to some degree from excluded middles except when used descriptively, i.e. this person is not "evil" per se but he does evil so I'm going to shoot him in the face.
The most challenging duality is appearance versus reality.
Plato noted this succinctly: good people hide their good deeds, and evil people (people intending evil; in Plato's vernacular, broken human designs) hide their evil deeds
This means that your greatest triumphs in life will be private, but your biggest fuckups public, unless you're a self-serving asshole.
All critics of ANUS.com should eat that carefully ;)

No, no its much more simple than that:
5 elements correlate to 10 organs (2 per element) and are differentiated by an internal and external manifestation.
