Propositional vs. Predicate LogicsA predicate language over a propositional language S is a couple qS = ( S , q ) where q is the signature of qS , i.e. the function which divides descriptive terms D ( q ) of qS into syntactical categories. All predicate languages involve the sets V ...

Modernsymbolic logic, of which the predicate calculus is a part, does not restrict itself, however, to the traditionalsyllogisticforms or to their symbolisms, a very large number of which have been devised. The predicate calculus usually builds upon some form of the propositional calculus. It the...
The meaning of PREDICATE CALCULUS is the branch of symbolic logic that uses symbols for quantifiers and for arguments and predicates of propositions as well as for unanalyzed propositions and logical connectives —called also functional calculus.

This new perspective, combined with much improved insights into the semantically defined discourse dependency of natural language sentences, leads to a novel and more functionally oriented approach to logic and to a reappraisal of traditional predicate calculus, whose main fault, undue existential import...
Propositional logic may be used to encode simple arguments that are expressed in natural language, and to determine their validity. The validity of an argument may be determined from truth tables, or using the inference rules such as modus ponens to establish the conclusion. Predicate logic allows...
