## What the subject saw and its core results

Terrence Deacon examines how mind and life arise from physical processes. He identifies three nested levels of dynamics. Homeodynamics covers thermodynamic dissipation. Morphodynamics covers spontaneous constraint formation in dissipative systems. Teleodynamics covers self-maintaining, goal-directed organization based on absence and constraint.

Core results establish that ententional phenomena such as function, information, and purpose emerge when constraints propagate through reciprocal morphodynamic processes. These processes produce higher-order teleodynamic systems. Mind emerges as nested teleodynamics within living systems.

## Exact primary works and passages

The primary work is Deacon, T.W. (2011). Incomplete Nature: How Mind Emerged from Matter. W.W. Norton & Company.

Key passages include: “Morphodynamic processes are the only spontaneous processes that generate and propagate constraints, and autogens demonstrate that reciprocity between morphodynamic processes can preserve and replicate constraints.”

“Teleodynamic systems can interact homeodynamically; homeodynamic relationships between teleodynamic systems can produce morphodynamic relationships; and synergistically reciprocal morphodynamic relationships constituted by interacting teleodynamic systems can produce higher-order teleodynamic relationships.”

“Teleodynamics can be understood as characterizing the distinguishing dynamics of life (p. 275).”

“[Teleodynamics is] the core property which links the selves of even the simplest life forms with that seeming ineffable property that characterizes the human experience of self (p. 466, p. 468).”

“Constraints are the present signature of what is absent.”

“The importance of physical regularity to the analysis of information is that it is ultimately what enables absence to matter.”

“Because organisms are teleodynamic systems, they do not merely react mechanically and thermodynamically to perturbation, but generally are organized to initiate a change in their internal deficits.”

“So surprisingly, this view of self shows it to be as non-material as Descartes might have imagined, and yet physical, extended, and relevant to the causal scheme of things as is the hole at the hub of the wheel.”

## Convergence patterns the work touches

The work touches the Ladder pattern through the progression homeodynamics to morphodynamics to teleodynamics. It touches flow networks and bounded chaos via constraint propagation in dissipative systems. It touches memory and scale invariance through replication of constraints across levels. It touches the Mirror Layer by treating absence as causally effective within physical processes that include observers.

## Distance from the full synthesis

Deacon provides a mechanistic account of the lower rungs of the Ladder up to mind. The account aligns with energy flows producing structural patterns via constraint. It stops short of explicit statements on the reader inside the system as Mirror Layer or on OIP invocation mechanics. The work supplies the dynamical substrate for the synthesis without addressing protocol-level object invocation or ledger receipts.

## Honest limits and disconfirming edges

The account relies on interpretive extension of thermodynamic principles to semantics and agency. Specific page citations for some absence claims derive from secondary summaries rather than direct verification in every edition. Reductionist objections note that constraint language restates known self-organization without adding novel predictions testable at molecular scales. No human empirical data set confirms teleodynamic transitions in vivo beyond analogy.
