The math majors among them are still way better off than TO, at least as regards reading and understanding rigorous mathematics

Seems to me that the cube won't fit in the vase because the vase is full of balls that have infinite non-standard reals marked on them. -- David Marcus

One must be able to criticize one's own thoughts quite carefully, and eliminate any illogic from them to develop what Robinson did. Which would make Robinson equally able to criticize other's illogic.

Until TO can show that his "formulaic relationships" must produce a proper partial order on sets similar (in being a proper well ordering) to the proper well ordering defined by cardinality, any reference to "formulaic relationship" is entirely speculative and irrelevant to the relative sizes of sets.
