In the context of the philosophy of logic, the conception of logic as calculus emphasizes that a logical system is primarily a tool for drawing inferences, a concept referred to by Gottfried Wilhelm Leibniz as a calculus ratiocinator.1

Under this view, the purpose of a logical system is to provide a mechanism for manipulation and deduction that can be theorized about, analyzed, and modified as needed. Unlike the conception of "logic as language," which views logic as a universal medium of communication, the calculus approach treats logic as a formal construct. Consequently, this perspective focuses on the validity and satisfiability of formulas rather than on truth or falsity, and it allows for the consideration of all possible universes of discourse rather than being restricted to a single, intended interpretation. This tradition is largely associated with the algebraic school of logic, which began with George Boole.12
