The concept is the fundamental unit of reality. It is not a mental abstraction, not a linguistic symbol, not a psychological construct. It is the primary ontological entity from which all existence—matter, mind, universes, gods—is derived. A concept has a precise internal anatomy composed of distinct logical layers. These layers determine how the concept exists, appears, behaves, and evolves across invocations.
A concept consists of two concepts which form its notional compartments: concept intension and concept extension.
Every concept is a category of its own. Every concept contains every other concept in its extension. Every concept is logically derived and exists as a logical necessity.
