It was Leibniz’s dream to develop a language (his lingua characteristica) capable of expressing all knowledge in a formal way and a grand algorithm (his calculus ratiocinator) capable of solving any problem expressed in his formal language.
In this way, “if controversies were to arise there would be no more need of disputation between two philosophers than between two accountants. For it would suffice to take their pencils in their hands, and say to each other: Calculemus.” (Gottfried Leibniz, Dissertio de Arte Combinatoria, 1666.)
