|Existential||individual, infinite||separate changing (real) from unchanging||reality found in appearances (themselves)|
|Substrative||individual, infinite individuations of common substratum||persists through change (substratum)||reality lies behind appearances (underlying)|
|Noumenal||general, one ideal individual apart from many||separate changing from unchanging (real)||reality lies behind appearances (transcending)|
|Essential||general, many individuals themselves||persists through change (essence)||reality found in appearances (that which appears)|
Since the Archic Matrix can be thought of as the union of four separate fourfolds, each of the fourfolds of perspective, reality, method, principle can be considered on its own. Here is the fourfold of realities consisting of existential, substrative, noumenal, and essential realities. The content of the table and the bottom figure is derived from Walter Watson’s Architectonics of Meaning.
