Based on the provided sources, particularly the work of Alicia Juarrero and Lila Gatlin, the diagram below illustrates how Causality (redefined as constraint) drives the formation of Hierarchy, which results in Non-Ergodicity (path dependence), ultimately allowing for Speciation (persistent identity) through the stabilization of those constraints.

Explanation of the Diagram Flow

1. Causality is Redefined as ConstraintIn this framework, causality is not merely “efficient force” (billiard balls hitting). It is the operation of constraints that alter the probability distribution of events[1],[2]. Constraints do not add energy but direct it, making some outcomes probable and others impossible[3].

2. Two Types of Constraints Build Structure

Context-Independent (CI): These act as barriers or gradients (e.g., a wall or a temperature difference). They take the system away from randomness (equiprobability) but do not create complex internal organization[4],[5].

Context-Dependent (CD): These connect parts so they are no longer independent (e.g., feedback loops, catalysts, grammar). They weave components into a coherent whole[6],[7].

3. Constraints Generate Hierarchy (Mereology)

Bottom-Up (Enabling): Context-dependent constraints link parts together to form a higher-level whole[8],[9].

Top-Down (Governing): Once formed, the whole acts as a constraint on the parts, regulating their behavior (e.g., the “spirit” of a mob constraining individual actions, or an organism regulating its cells)[8],[10]. This circular causality creates Hierarchy[11].

4. Hierarchy Leads to Non-ErgodicityBecause the system is now structured by these internal constraints, it cannot do “just anything.” It is restricted to a specific trajectory based on its history and context. It does not visit every possible state (Ergodicity); it stays within a specific “basin of attraction”[12],[13]. The system “carries its history on its back”[13],[14].

5. Isolation and Stability Create SpeciationTo persist as a distinct entity or Species, this unique non-ergodic path must be protected from dissolving back into randomness.

Isolation: Geographical or reproductive isolation acts as a constraint that prevents the system from homogenizing with the environment[15],[16].

Unity of Type: This results in a stable “Constraint Regime” that defines the species. The species persists because it reproduces this specific set of constraints[17],[18].
