In mathematical logic, Zermelo–Fraenkel set theory with the Axiom of Choice (ZFC) serves as a standard framework for much of mathematics, providing axioms that govern the behavior of sets. Morse–Kelley set theory (MK) extends this framework by incorporating classes—collections too large to be sets—allowing for a richer ontology. MK's comprehension schema is more robust, enabling the formation of classes defined by properties that quantify over all classes, thus offering greater expressive power. However, this increased expressiveness results in a higher consistency strength compared to ZFC. citeturn0search12
Open Questions
- What are the implications of adopting MK over ZFC in terms of the foundational aspects of mathematics?
- How does the inclusion of proper classes in MK influence the development of mathematical theories compared to the set-only approach of ZFC?
- What are the consistency strengths of ZFC and MK, and how do they compare?

Alternative set theories provide diverse frameworks for understanding the concept of sets, each with its own axioms and foundational principles. For instance, Von Neumann–Bernays–Gödel (NBG) set theory extends ZFC by incorporating classes as distinct entities alongside sets, allowing for a richer structural analysis. Ackermann set theory introduces a distinction between sets and classes, with specific axioms governing their interactions. New Foundations (NF), proposed by Quine, modifies the comprehension axiom to avoid paradoxes, leading to a unique set-theoretical landscape. Positive set theory focuses on positive comprehension axioms, restricting the use of negation to explore constructive aspects of set formation. Each of these theories offers a unique lens through which to examine the foundations of mathematics, highlighting the versatility and depth of set-theoretical research.
