Based on the provided sources, the relationship between these concepts describes how complex systems emerge from thermodynamic flux to become stable, history-dependent entities.

The Theoretical Framework

1. Hierarchy & Constraint: Hierarchy is defined by differences in rates. Slower, larger levels (the Environment/Context) constrain faster, smaller levels (the Parts). This constraint is “passive”—the upper level sets the boundary conditions[1][2].

2. Non-Ergodicity (Frozen History): In a purely physical world, everything is dynamic flux. Non-ergodicity occurs when specific events (historical accidents) are “frozen” into static structures or codes (like DNA or culture). These codes are rate-independent rules[1][3]. They act as a memory of the past.

3. Speciation (The Surface): Speciation is the creation of a surface or boundary. This surface isolates a specific set of non-ergodic rules (the “frozen history”) from the general population. Without this isolation, the specific history would be “averaged out” by the environment. Speciation protects the internal code, allowing the system to become distinct[4][5].

4. Causality: The system (Holon) is maintained by a cycle of Aristotelian causes. The Efficient Cause (energy gradient) drives the Material Cause (parts), but this flux is harnessed by the Formal Cause (the non-ergodic plan/code) to fulfill a Final Cause (role) in the hierarchy[6].

Explanation of the Diagram

The Vertical Axis (Hierarchy): The diagram is arranged vertically to represent Hierarchy. The top (Final Cause) operates slowly and provides meaning/context[7]. The bottom (Material/Efficient Cause) operates quickly and provides energy/matter[1][8].

The Constraint Arrows (Downwards): The red arrows represent Constraint.

    ◦ The Environment (Final Cause) constrains the Holon not by acting, but by not acting—it is too slow to respond to high-frequency changes, thus acting as a stable boundary[2][9].    ◦ The Formal Cause (Rules) constrains the Material Cause (Parts). The code (DNA) dictates how the energy is used, preventing the parts from simply reaching thermodynamic equilibrium[10][11]. • The Role of Speciation & Non-Ergodicity:

    ◦ Non-Ergodicity is the “memory” of the system. It converts dynamic, rate-dependent events into static, rate-independent rules[12][13].    ◦ Speciation is the event that creates the surface (boundary) around this memory. As the source notes, “Dissection by surfaces allows change. Without isolation, the mass remains stuck at some average condition”[4]. Speciation ensures that the “frozen accident” (history) survives to guide the system. • The Cycle of Causality: The Holon exists where these forces meet. It uses the Efficient Cause (energy) to build itself according to the Formal Cause (plan), within the Constraint of the Final Cause (environment)[6][14].
