Different proof systems, distinguishing logical rules from domain axioms
Manage episode 301333574 series 2823367
I highlight two basic points in this continuing warm-up to proof theory: there are different proof systems for the same logics, and it is customary to separate purely logical rules (dealing with propositional connectives and quantifiers, for example) from rules or axioms for some particular domain (like axioms about arithmetic, or whatever domain is of interest).
