## What Aquinas Saw

Thomas Aquinas saw the universe as ordered by purpose. Every thing moves toward an end. Natural objects act as if directed. This direction points to an intelligent source.

His core result was a set of proofs for God's existence. These proofs start from observed change and causation. They end at a necessary being.

Aquinas built on Aristotle. He folded Aristotelian ideas into Christian theology. The result was a systematic account of being, causation, and final causes.

## Primary Works and Passages

The main text is the Summa Theologica. It was written between 1267 and 1273. The Five Ways appear in Prima Pars, Question 2, Article 3.

A key passage states: "The existence of God can be proved in five ways. The first and more manifest way is the argument from motion." This comes from the newadvent.org translation of the Summa Theologica.

Another central work is the Summa Contra Gentiles, completed around 1265. It develops arguments for God and divine providence in greater detail.

Aquinas also wrote commentaries on Aristotle's Physics and Metaphysics. These show his engagement with natural motion and causes.

## Convergence Patterns Touched

Aquinas touches the pattern of directed flow. The Fifth Way describes things acting for an end. This matches the grain's emphasis on reliable structural patterns such as flow networks and purpose-like behavior.

He addresses memory and structure through the doctrine of forms. Substances carry inherent tendencies. These persist across instances.

The Ladder appears in partial form. Difference leads to motion. Motion leads to structure. Structure leads to directed ends. Yet the top of the Ladder remains transcendent rather than immanent.

See /a/oip-the-ladder for the full sequence from difference to mind.

## Distance from the Full Synthesis

Aquinas stands at a clear gap from the OIP/GRAIN synthesis. No source document in the GRAIN corpus cites the Five Ways or analogical predication.

His theism places the source outside the system. GRAIN describes an immanent order where patterns arise from energy flows within the universe. Aquinas requires a creator who stands beyond the created order.

The Mirror Layer concept finds no parallel. Aquinas places the reader inside creation yet dependent on revelation for full knowledge of the source.

## Limits and Disconfirming Edges

The synthesis remains a modern lens. Aquinas's words stay his own. No retroactive claim of endorsement holds.

A reductionist objection applies. Weinberg-style accounts explain order through physical laws alone. They require no final cause or external director. Aquinas's proofs do not rule out such accounts.

The transcendent frame conflicts with GRAIN's immanent grain. Patterns in Aquinas serve a personal God. In GRAIN they emerge from reliable physical processes.

See /a/oip-principles for the immanent rules of the synthesis.

See /a/oip-final-testimony for the boundary conditions of the full system.

## How the Work Maps onto Specific Patterns

Branching appears in the hierarchy of causes. Efficient causes form chains that terminate in a first cause.

Symmetry and scale invariance show in the analogy of being. Predicates apply to God and creatures in related but not identical ways.

Bounded chaos receives indirect treatment. Contingent beings could fail to exist. Yet necessity anchors the system.

The work stops short of memory as physical encoding. It treats knowledge as participation in forms.

## Honest Assessment

Aquinas supplies a strong account of teleology. That account aligns with one convergence pattern but stops at the boundary of immanence. The gap remains documented and unbridged in the source material.
