Bronowski[1]:
When you have no written language […] then you must have a precise ceremonial which fixes the sequence of operations so that they are exact and memorable.
Social-semiotic rituals are a means of providing copying fidelity in the reproduction of a community’s model of the perceivable, generation after generation, when there is no durable expression modality. The ordered structure of ritual maintains the stability of the socio-semiotic lineage: both the semiotic model and social system it organises.
Participation in the meaning-making of a ritual is selection of the meanings being expressed. Participation also raises the value of the meanings being expressed for both participants and observers, thereby increasing the probability that it will be re-expressed in the future by increasing the motivation to do so.[2]
