class theory
Class theory is a branch of logic and mathematics that studies collections of objects called "classes," which may be too large to be sets (like the collection of all sets). It helps address foundational questions about what kinds of collections exist and how they relate. In essence, class theory provides a framework for understanding and managing large collections, avoiding paradoxes that arise when treating everything as a set. It is used to formalize and analyze concepts in set theory, mathematics, and logic, ensuring consistency and clarity when dealing with very large or complex groupings of objects.
