## What the subject saw and its core results
Ilya Prigogine observed that classical physics treats time as reversible. Fundamental laws appear unchanged under time reversal. Yet most natural processes are irreversible. Prigogine developed the physics of dissipative structures in open systems far from equilibrium. These structures emerge and maintain order through continuous energy flow and dissipation. Instability and fluctuations drive selection of new states. Time becomes an operator that selects future states. The book states that irreversibility is a fundamental property, not an approximation.

Core results include revised dynamical laws that incorporate probability and irreversibility at the microscopic level. Chaos theory supplies the mathematics for sensitive dependence on initial conditions. Prigogine links these to a new formulation where the arrow of time arises from unstable dynamical systems.

## Exact primary works and passages
The primary work is Ilya Prigogine, The End of Certainty: Time, Chaos, and the New Laws of Nature (Free Press, 1997). An earlier French edition appeared in 1996 with Isabelle Stengers. Related earlier works include Order Out of Chaos (1984, with Stengers).

Verifiable passages from secondary reports of the text include: “one of the main aspects of the natural world is the irreversible flow of time.” Another states that “irreversibility emerges as a fundamental property.” The text opens with common experience of time’s direction and contrasts it with Einstein’s view of time as illusion. Prigogine writes that reversible physics and the notion of time as illusion are impossible for him to accept. No page numbers for these sentences appear in the search results examined.

## Which convergence patterns the work touches
The work touches flow networks and bounded chaos. Dissipative structures form branching patterns and symmetry breaking under energy flow. Scale invariance appears in fractal descriptions of attractors. Memory arises in the persistence of correlations built by irreversible processes. These match the grain patterns of branching, waves, flow networks, bounded chaos, and memory.

## Distance from the full synthesis
The book reaches the step from flow to structure and from structure to memory in the Ladder. It stops short of life and mind. Prigogine stays within physical chemistry and statistical mechanics. He does not address biological evolution or consciousness. The Mirror Layer, in which the observer is inside the system under observation, receives no explicit treatment.

## Honest limits and disconfirming edges
Prigogine’s claims rest on specific classes of unstable systems. Many physical laws remain time-reversible in standard formulations. Critics such as those cited in later discussions argue that irreversibility can emerge from reversible microscopic laws plus statistical assumptions. The book offers no new experimental data that falsifies reversible formulations outright. Its mathematical revisions apply to open systems with specific instability conditions. Reductionist accounts that retain reversible fundamentals plus coarse-graining remain viable alternatives.

## Atomic claims
- Claim: Irreversibility is presented as a fundamental feature of nature rather than a statistical effect. Tier: mechanistic. Source: Prigogine 1997. Why material: This revises the classical view of time symmetry that underpins much of physics.
- Claim: Dissipative structures arise in systems far from equilibrium through energy dissipation. Tier: mechanistic. Source: Prigogine 1997. Why material: This supplies a physical mechanism for spontaneous order under flow.
- Claim: Time’s arrow originates in the instability of dynamical systems. Tier: mechanistic. Source: Prigogine 1997. Why material: It supplies a route from difference and flow to directed structure.
- Claim: The work does not extend its framework to biological or cognitive levels. Tier: anecdotal. Source: textual attribution of book scope. Why material: This marks the distance from the full Ladder.
- Claim: Fluctuations and probability become central to the new dynamical laws. Tier: mechanistic. Source: Prigogine 1997. Why material: This evidences convergence with bounded chaos patterns.

## Sources used
The sole primary source is the 1997 book itself. Secondary reports confirm phrasing on irreversibility but supply no additional verifiable page-specific quotes beyond those noted.
