Abstract

Cross-linguistic evidence from widespread modes of language variation and change demonstrate that language evolution proceeds (at least in part, perhaps in whole) by breaking and renewing symmetrical patterns. Since this activity is identified with semiosis (Nöth 1994, 1998), these patterns-in-process establish further grounds for insisting that the science of language be more adequately situated within semiotic understanding as “an ideoscopic science and sub-discipline under the general doctrine of signs” (Deely 2012: 334). After summarizing the theoretical context of my thesis, including relationships between analogy, symmetry, and linguistic diagrammatization, I present supporting comparative data in successive stages of complexity, ranging from simple reversals of linguistic diagrams through time to the emergence of more involved linguistic mirror patterns, to the emergence of intertwining diagrams and linguistic fractal symmetries. I then point back to the embodied and psychological sources of these patterns in the primary modeling system of the human Umwelt. The essay ends with gestures toward further unexplored sources of evidence and a summary proposal for understanding language evolution as non-linear process, qua semiosis.
