First-order logic is the standard for the formalization of mathematics into axioms and is studied in the foundations of mathematics.

Standard translation, an embedding of modal logics into first-order logic which captures their possible world semantics N-universes Modal fictionalism Fictionalism.
First-order logic also satisfies several metalogical theorems that make it amenable to analysis in proof theory, such as the Löwenheim- Skolem theorem and the compactness theorem.
Later, he worked mainly on game semantics, and on independence-friendly logic, known for its"branching quantifiers", which he believed do betterjustice to our intuitions about quantifiers than does conventional first-order logic.
There are many deductive systems for first-order logic that are sound(all provable statements are true in all models) and complete(all statements which are true in all models are provable).
First-order logic- also known as first-order predicate calculus and predicate logic- is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science.
Although support for higher-order programming takes Prolog outside the domain of first-order logic, which does not allow quantification over predicates, ISO Prolog now has some built-in higher-order predicates such as call/1, call/2, call/3, findall/3, setof/3, and bagof/3.
