Peirce gave no system of axioms for first-order logic, although his “existential graphs” are a complete proof procedure for first-order logic (an early form of natural deduction). (Putnam 1982: 298)

First-order logic (FOL) is built around the above 3 elements Higher-order logic: views the relations and functions in FOL as objects themselves / T,F,U. ▫.

But if you care about natural deduction representations of first-order logic, Jape is probably the best fit. $\endgroup$ – Charles Stewart Feb 18 '10 at 13:58 Teaching First-Order Logic with the Natural Deduction Assistant (NaDeA) From, Asta Halkjær; Hatteland, Helge; Villadsen, Jørgen Publication date: 2018 Document Version Publisher's PDF, also known as Version of record Link back to DTU Orbit Citation (APA): From, A.

5 Deduction in First-Order Logic The system FOL C. Let C be a set of constant symbols. 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

FOL is sufficiently expressive to represent the natural language statements in a concise way.

The following sections provide the basics of a typical logic, sometimes called “classical elementary logic” or “classical first-order logic”. Section 2 develops a formal language, with a rigorous syntax and grammar. The formal language is a recursively defined collection of strings on a fixed alphabet.

Similar are essentially sequent-calculus adaptations of Martin-Löf's natural deduction. May 30, 2013 So there is an interplay between the rules of inference and the axioms of a given theory. The deduction theorem for first order logic shows that this Sep 13, 2020 With the birth of formal logic, new types of deduction emerged, and to for a class of the first-order theories axiomatized by universal axioms.
