Hello, any suggestions on how to program set theory?
Suppose that I have a notation set up well, and I have a set of rules 
of implication.  The next step is to teach mathemania how to compute...
For example, I define a notation for AbstractComplement[X,A], and I 
want to associate it with it the rule 
In other words, a point can't be in a subset and its complement.  My 
feeling is that alone this rule should be enough to decide the 
falsehood of a statement such as 

where in this case i've purposefully changed the variables because i 
don't want to tie the rule to any particular symbols.  How can we set 
up Simplify,Reduce,Refine or something similar to decide on this rule? 
Especially, without having to make the rule explicit in the expression 
to simplify. Christopher Arthur
