What Significant Achievements have Linguists Made? At the Heart of the Problem of Continuity of Language

Background: In the Kyoto School of Linguistics, which originated with Dr. Hisanosuke Izui, scholars have made great accounts of the continuity of language that represent a significant achievement in 20th century linguistics. Objective: In this paper, we assert that Eugenio Coseriu in Europe and Dr. Hisanosuke Izui in East Asia attempted to overcome Saussure’s Antinomy of synchrony and diachrony based on the language viewpoints of Wilhelm von Humboldt. Results: In a particular utilitarian effort to illustrate the continuity of language, the Kyoto School of Linguistics developed two models: one is a linear schematization using one attribute, and the other is an octahedron. Conclusion: The three-way model and the triangle model of C.S. Peirce may be more applicable to these complex systems.
