Mereo-relational Theory: A theory in first order logic with identity "=", part-hood "p" and Ordered pair "()".
Axioms: Identity theory axioms + (1) x p x (2) x p y & y p z > x p z (3) x p y & y p x > x=y Define (pp): x pp y <> x p y & ~y p x Define (O): x O y <> Exist z. z p x & z p y (4) x pp y > Exist z. z p y & ~ z O x. Define(atom): x is atom <> ~Exist y. y pp x (5)Exist z. phi > (Exist x. for all y. y O x <> Exist m. phi(m) & y O m) Define (whole of (phi)s): x is a whole of (phi)s iff whatever overlaps with x do overlap with an object satisfying phi. (6) Exist x. for all y. y p x > Exist z. z pp y Define(void): x is void <> for y. y p x > Exist z. z pp y (7) Every ordered pair of wholes of atoms is void (8) Every ordered pair of wholes of void ordered pairs is an atom. (9) Ordered pairs are identical iff they have exactly the same projections. (a,b)=(c,d) <> a=c & b=d / Theory definition finished.
I think this is consistent and it can prove Z! However the main question is if it can prove ZF?
