As I’ve worked with the cycle of visions, I’ve always found the rise and fall of successive visions and the interactions among them fairly easy to identify . The hard part is figuring out the source of this recurring pattern and the mechanisms that keep it going over vast stretches of time and space with an amazing degree of regularity.
I’ve used a variety of analogies to attack this question, but the one that appears most relevant is language.
The central feature of language is that it is rules-based. Toddlers who are just learning to talk string words together loosely, but they don’t produce fully-formed sentences. The complete range of human speech becomes available to them only once they master the detailed grammatical rules that indicate how the elements of a sentence fit together.
Different languages employ different rules but the capacity for creating and learning rules-based systems appears to be innate — and it is not confined to language. It also underlies our love of games. It is the basis of law and government. It plays a role in both art and science.
Rules-based system are naturally coherent because the same rules always apply under similar circumstances. This is why speakers can utter novel sentences and still be understood. It is why judges or gamemasters can hand down decisions and feel confident they will be accepted.
