predicate calculus

(Or "predicate calculus") An extension of
propositional logic with separate symbols for predicates,
subjects, and quantifiers.

For example, where propositional logic might assign a single
symbol P to the proposition "All men are mortal", predicate
logic can define the predicate M(x) which asserts that the
subject, x, is mortal and bind x with the {universal
quantifier} ("For all"):

All x . M(x)

Higher-order predicate logic allows predicates to be the
subjects of other predicates.
