I've been asking myself a few questions lately regarding the nature of a theory. It can be any type of theory. I hope someone can answer these to a degree. The questions are: Can a theory have less than three axioms? Is three the minimum for a theory to make sense? Is the statement "The less axioms, the more abstract the theory, the more facts will fit" true ? How does the number of axioms relate to the number of contradictions that may appear within the theory? Thanks in advance.
