INTRODUCTION

English translation pending.

CORE DEFINITION

A symbolic system from the Yijing, in which three lines, each either broken or unbroken, combine into eight trigrams representing categories such as heaven, earth, thunder, wind, water, fire, mountain, and lake. The core proposition is that a small set of binary oppositions can generate a compact taxonomy of states and the transitions between them. The key qualification is its status as a classificatory and interpretive schema rather than a predictive science.

SCAFFOLDING EFFECT

Reduce cognitive load

- State mapping: assign a complex situation to one of a small set of categories. - Binary encoding: describe the current state using paired opposite qualities. - Transition reading: use the relations between trigrams to reason about how a state may change.

Anchor fast decisions

Combining two values across three positions produces exactly eight distinct patterns, which gives a compact address space for describing situations. Because the patterns are defined by oppositions, they highlight tensions and complementary forces rather than quantities. Their relational structure then supports reasoning about how one state tends to move into another.
