gotta give the short form for now---at work between clients.
1. concept formation. set theory duality between elements and
bijective relations between element that compose the set. also know
as the duality between elements and relations.
2. concept formation and phenonmenon. because we have a name for
something doesn't mean it exists as a single close phenomenon
3. use wave-particle duality in quantum to illustion there is
something fundamentally wrong with out culturally determined
concept of particle and wave.
