What “dual” means here

The Paradigm of the Great Life reads every phenomenon through two complementary lenses:

• Objective (Metaphysical Realism): the physically conserved substrate of change — Energy.
• Subjective (Metaphysical Anti‑Realism): agent‑dependent meaning formed by Context — Information.

Both sides are necessary. One‑sided models miss either how the world constrains us or how agents make sense and act.

Objective side: Energy

• Energy is the conserved substrate of physical change.
• It underwrites what sensors can register (signals, fields, work, heat).
• Objective models specify dynamics, symmetries, conservation, and statistics.

Subjective side: Information

• Information is agent‑dependent meaning relative to a model (Context).
• It underwrites why a signal “matters,” how it is interpreted, and what action follows.
• Subjective models encode priors, goals, hypotheses, uncertainties, and costs.

Why one‑sided models fail

• Purely objective: ignores how agents compress, interpret, and decide under constraints; misses control, goals, and failure modes tied to modeling.
• Purely subjective: ignores physical constraints, conservation, and reproducible statistics; drifts into unconstrained stories.

How to apply the dual stance (checklist)

• Declare the objective constraints (dynamics, conservation, data‑generating process).
• Declare the agent layer (who owns the model Q, sensors, actuators, goals, and budgets).
• Separate source statistics $P$ from agent beliefs $Q$; measure mismatch (e.g., $D_{KL}(P \|\| Q)$).
