## What the work establishes
Prigogine presented the talk in 1967 at the International Conference on Theoretical Physics and Biology in Versailles. It was published in 1969 as a chapter in Theoretical Physics and Biology, edited by M. Marois, pages 23–52, North-Holland.

The core result is the identification of dissipative structures. These are ordered states that arise and persist only through continuous dissipation of energy and matter in open systems far from equilibrium.

Irreversible processes, previously seen as sources of disorder, can instead generate new dynamic states of matter when driven beyond a critical threshold.

## Exact load-bearing passages
The title itself states the link: Structure, Dissipation and Life.

A verifiable passage from the talk states: “But the most exciting perspective is the possibility of combining the unity of matter with a clear distinction of what is life and what not as these two states of matter would be separated by an instability corresponding to a critical affinity. Therefore there appears at least some hope of reconciling the basic duality of our experience with the unity of the laws of nature.” (Cited in Lefever 2018, Royal Society, from the 1967 presentation.)

Earlier references in the Nobel lecture and related works restate the definition: irreversible processes may lead to dissipative structures.

No page-by-page full text is publicly quoted verbatim beyond these summaries in secondary sources.

## Convergence patterns touched
The work evidences the pattern of energy flow producing structure. Thermodynamic gradients drive self-organization into stable, ordered forms that would collapse at equilibrium.

It supports branching and flow networks through chemical instabilities and reaction-diffusion processes.

It directly addresses the step from flow to structure to life in the Ladder sequence.

It shows memory-like persistence: once formed, dissipative structures maintain their organization through ongoing throughput.

## Relation to the OIP/GRAIN synthesis
The 1969 chapter supplies a mechanistic foundation for the grain of the universe. Energy flows reliably yield a narrow family of structural patterns under non-equilibrium conditions.

It aligns with the Ladder from difference and flow to structure and life.

It remains inside the system: the observer studies open thermodynamic systems of which living matter is one instance.

Distance from full synthesis is moderate. The paper stays within physico-chemical and early biological examples. It does not extend to mind, Mirror Layer reflexivity, or protocol-level invocation and ledger mechanics.

## Honest limits and disconfirming edges
The analysis is confined to macroscopic thermodynamic descriptions and model chemical systems such as the Brusselator. It offers no direct experimental data on living cells in the 1969 text itself.

Later reductions, in the style of Weinberg, note that dissipative structures emerge from underlying quantum and statistical mechanics without requiring new fundamental laws.

The work predates Prigogine’s fuller treatments in Order Out of Chaos (1984) and does not address scale invariance across cosmic or cognitive domains.

No claim is made for universality beyond far-from-equilibrium thermodynamics.

## Claims
- Claim c1: Dissipative structures form and persist solely through continuous energy dissipation in open systems. (mechanistic, source s1)
- Claim c2: An instability at critical affinity separates equilibrium states from ordered dissipative states. (mechanistic, source s1)
- Claim c3: Irreversible processes can generate order rather than only disorder under non-equilibrium conditions. (mechanistic, source s1)
- Claim c4: The 1969 paper first publicly coins the term dissipative structures in a biological context. (anecdotal, source s2)
- Claim c5: The framework remains limited to physico-chemical models and does not address cognitive or reflexive layers. (speculative, unsourced)
