Zeichen und Bedeutung bei Ludwig Friedrich Gottlob Frege

Overall, the analysis of the relationship between signs and meaning in Frege's logical symbolism shows that logical argumentation only gains epistemological value when it operates solely through written signs, to which a single meaning is assigned within a specific symbol system. The doctrine that arises from this preference for written signs over oral signs is the doctrine of rigor and precision, which must necessarily influence the realm of scientific knowledge. In Frege's logical symbolism, written signs are superior to oral signs and enable us to reach the highest level of knowledge, the level of pure knowledge that is not dependent on the senses.
