FOL C is a system of deduction for the language L# C. Axioms: The following are axioms of FOL C. (1) All tautologies. (2) Identity Axioms: (a) t= t for all terms t; (b) t 1 = t 2!(A(x;t 1) !A(x;t 2)) for all terms t 1 and t 2, all variables x, and all formulas Asuch First-order logic—also known as predicate logic, quantificational logic, and first-order predicate calculus—is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science.

1 Inference in First-Order Logic 2 First-Order Deduction •Want to be able to draw logically sound conclusions from a knowledge-base expressed in first-order logic. •Several styles of inference: The FOL Evaluator is a semantic calculator which will evaluate a well-formed formula of first-order logic on a user-specified model. In its output, the program provides a description of the entire evaluation process used to determine the formula's truth value. 2.

First-order logic is also called Predicate logic and First-order predicate calculus (FOPL). It is a formal representation of logic in the form of quantifiers. In predicate logic, the input is taken as an entity, and the output it gives is either true or false.

I am struggling with a particular case in the (inductive) proof of Theorem 2.8.3 (i) of Logic and Structure by Dirk Van Dalen ( c ≠ x in the Theorem statement is a variable) The cases when we consider proof trees for Γ ⊢ ϕ for all rules but and-elimination/if-elimination I don't encounter any difficulty First-order logical consequence can be established using deductive systems for rst-order logic. In particular, extensions of the Propositional Semantic Tableau and Natural Deduction, with additional rules for the quanti ers, can be constructed that are sound and complete for rst-order logic.
