Preliminaries,ose which are different for different logical languages; the syntax specifies what strings of symbols are meaningful (formulas) in logic, and the semantics specifies the truth-values of formulas under an assignment (or a model).

Cupping

Nonmonotonicity of R-Calculus, logic, first-order logic, modal logic, etc., are monotonic. The nontraditional logics, such as default logic, R-calculi, autoepistemic logic, circumscription, etc., are nonmonotonic. The nonmonotonicity of a nonmonotonic logic follows from using a negation . of a monotonic deduction . [.]. We found
