How Anything Gets Sorted Into One of the Five Elements

🔊This unit has, across many lessons, assigned organs, colors, sounds, odors, flavors, and emotions to one of the five elements, without pausing to explain how any given item ends up in one category rather than another. The underlying method is called "comparison and categorization": each element is defined by a small set of characteristic qualities — wood by growth and flexible expansion, fire by warmth and upward movement, earth by stability and nourishing transformation, metal by contraction and clearing, water by coolness and downward flow — and anything observed in the world is sorted by comparing its own qualities against those five reference profiles.

🔊This explains why the assignments this course has covered aren't arbitrary lookup-table entries to memorize by rote: the liver is assigned to wood because it's traditionally credited with a smooth, unobstructed, expansive function similar to a growing plant; anger is assigned to wood because a surge of anger produces an upward, expansive, hard-to-contain quality similar to rapid growth. Once the underlying qualities of an element are understood, many of this unit's individual correspondences become predictable rather than needing to be memorized as isolated facts.

🔊This is also why the same method can, in principle, keep extending indefinitely to items this course hasn't covered: a food, a weather pattern, a personality trait, a stage of an illness — anything with an identifiable set of qualities can, in theory, be compared against the same five reference profiles and sorted accordingly. The five-element system was never meant to be a closed list of five-item categories; it's a method for sorting, applicable to anything new that comes along, which is also why practitioners across centuries kept finding new items to add to each category without ever needing to invent a sixth element.
