This paper traces the complete chain from the axiom σ = 1/(1+σ) to the emergence of biological life. The axiom generates the constants (α, G, Λ). The constants determine atomic structure. Atomic structure enables chemistry. Chemistry enables molecular complexity. Molecular complexity enables self-replication. Self-replication is self-reference at the biological level. Life is the axiom expressing itself at the macroscopic scale. The paper identifies the precise points where physics becomes chemistry, chemistry becomes biology, and biology becomes self-awareness — arguing that each transition is a recurrence of the same self-referential pattern at a higher scale.
