Explore: Propositional Logic

Propositional logic is a branch of logic. It is also called statement logic, sentential calculus, propositional calculus, sentential logic, or sometimes

concepts. In relation to the mind, propositions are discussed primarily as they fit into propositional attitudes. Propositional attitudes are simply attitudes

of propositional logic, or valid sentences of predicate logic that can be reduced to propositional tautologies by substitution. Propositional logic begins

This is similar to a way of axiomatizing classical propositional logic. In propositional logic, the inference rule is modus ponens MP: from ϕ → ψ {\displaystyle

classical logic. It consists of propositional logic and first-order logic. Propositional logic only considers logical relations between full propositions. First-order

propositional logic, a propositional formula is a type of syntactic formula which is well formed. If the values of all variables in a propositional formula
