Predicate Logic. A predicate is a statement that contains variables (predicate variables) and that may be true or false depending on the values of these predicate variables. Predicates are the propositions containing variables and represent properties or relations among objects.

It retains the central tenet of Propositional Logic: that sentences express propositions and propositions denote truth-conditions. The difference between these logics is that the basic building blocks of Predicate Logic are much like the building blocks of a sentence in a 10.

Predicate Logic has two such quantifiers: ∀ (the universal quantifier) and ∃ (the existential quantifier). Since a predicate can combine with more than one variable, it is necessary to write the variable immediately after the quantifier to indicate which variable the quantifier interacts with.

PREDICATE LOGIC Predicate Instantiated/Domain A predicate instantiated (where variables are evaluated in specific values) is a proposition. The domain of a predicate variable is the collection of all possible values that the variable may take.
