An example of BB's incoherence...
JOG states:
<< 1) Lego blocks are /not/ the same. They always have a different
location attribute.
2) Hence their x,y,z position attribute always identifies them.
3) However this identifer is very hard to record and keep track of,
even though it exists. >>.
Bob Badour responds:
<<To amplify, the location might be familiar and perhaps even unique,
but
it is neither simple nor stable. >>
In other words, it can not be a primary key. This is totally
incoherent. BB *amplifies* a theory by stating its exact opposite.
Location is not a key for LegoBlock. Period.
