Predicate Calculus

Functional logic / quantification logic, formalized as predicate calculus, is a development of Frege's early predicate logic.
Propositional Logic
is a simpler logical system, while predicate logic is more sophisticated, allowing us to express objects, their properties, and relations between objects. It is a logic that uses quantifier symbols for objects that can be subjects in the subject-predicate structure that exists in propositions. Therefore, unlike propositional logic, it can handle inference rules based on the analysis of the internal structure of propositions, whereas in propositional logic, the proposition is the minimum unit, so analysis of the internal structure of propositions cannot be performed. Predicate logic was independently invented by Gottlob Frege in Europe and Charles Sanders Peirce in America.
