Query: The Notion "Pathology" in Set Theory   When we study the paradoxes of set theory we find out that there are mainly 2
types: the pathologies and the antinomies. These 2 notions are made precise and
compared with the somehow inductively definable concept "abnormal". (See my
paper "Naive Axiomatic Mengenlehre for Experiments" in arXiv.) In the following
5 Patho Theses are discussed in order to formalize this notion of pathology.
This allows us to define formally the property "Hereditary-non-Pathological"
for well-formed formulas. With this property the system NACT* of Naive
Axiomatic Class Theory is constructed, which has a "unique maximal" universe
(in a special sense).
