## 1. Aquinas: distinct commitments, not one self-explanatory word

**[T] Participation and causality.** [ST I.44.1](https://www.newadvent.org/summa/1044.htm) argues that what has being by participation is caused by what has it essentially; the argument invokes earlier conclusions that God is subsisting being and that subsisting being is one. This is not a deduction from the bare word *participation*. It imports substantive commitments about essential possession, causal priority, and uniqueness. The reply to objection 1 distinguishes the essence or definition of a caused thing from its consequent relation to its cause. The reply to objection 2 explicitly allows necessary beings to have causes of their necessity.

**[C] Formal consequence:** do not define dependence as merely “would not exist if its source did not exist.” With a necessary source that counterfactual may be vacuous; necessary derivative beings can still depend. An explanatory or productive dependence relation must carry more information than modal covariance. Conversely, dependent actuality alone does not establish likeness, infinite source, or freedom.

**[T] No shared genus.** [ST I.3.5](https://www.newadvent.org/summa/1003.htm) denies that God belongs to a genus, either as a species or as the principle reducible to that genus. Its grounds include the distinctions between essence/existence and actuality/potentiality, and God's universal causal scope. It does not infer non-generic status from numerical difference alone. In I.4.3 the creature's likeness is explicitly distinguished from sameness of specific or generic formality. There is real likeness through analogy, rather than a divine and creaturely species under a common genus.

**[T] Causal likeness has a bridge.** [ST I.4.2–3](https://www.newadvent.org/summa/1004.htm) argues that an effect's perfection must be in its effective cause either under the same formality or more eminently. Every agent produces an effect according to its form; this motivates some resemblance even in non-univocal causality. I.4.3 distinguishes equal likeness, unequal likeness within the same formality, and analogical likeness without common specific/generic formality. **[R]** Thus causal adequacy is a metaphysical principle employed by Aquinas, not a theorem of the uninterpreted relation “causes.” A contemporary formalization must state the bridge openly.

**[C] Semantic safeguard:** a common predicate or representational “perfection coordinate” is not automatically a genus. A genus is a shared categorial essence specified by differences. Nevertheless, if the formal representation makes God and creatures instances of exactly the same intrinsic property-kind and differs only by degree, it has quietly recreated what the stronger analogical account rejects. Separate positive perfection from its created realization; spatial shape and color cannot simply be attributed to God in the same way as to bodies.

**[T] Reception belongs to the recipient.** ST I.84.1 states that “the received is in the receiver according to the mode of the receiver,” explaining why the intellect's immaterial reception of a bodily form does not make the external thing immaterial. I.12.4 similarly separates the object's being from the knower's mode. I.89.4 applies the general recipient principle to infused cognitive species. **[R]** These are particularly useful anti-smuggling texts: knowing or expressing something under a finite mode does not transfer that mode into the thing known or expressed. They are not, by themselves, proofs that any source is unlimited.

**[T] Infinity needs ontology.** [ST I.7.1](https://www.newadvent.org/summa/1007.htm) derives divine infinity from subsisting being not received in anything, within Aquinas's account of matter/form and contraction. I.7.2 distinguishes a form's relative independence from matter from absolute infinity: created immaterial forms still receive being. **[C]** “Unreceived in respect r” is weaker than “unlimited in every respect.” A finite brute independent source is a logical countermodel unless a separate limitation principle excludes it. Non-exhaustion therefore belongs to an infinity layer, not the generic definition of participation.

**[T] Presence without constituency.** [ST I.3.8](https://www.newadvent.org/summa/1003.htm) excludes God as either material or formal component of creatures. The reply to objection 1 construes God as their efficient and exemplar cause, not their essence; objection 2's uncreated form is answered as exemplar, not constituent form. [I.8.1](https://www.newadvent.org/summa/1008.htm) then gives the positive account: God is present as agent, sustains being for as long as the creature exists, and is intimate because being is innermost. This combines production, conservation, and non-constitution. **[R]** An initial-cause axiom alone leaves deism open; continuing causal dependence is required for the intended intimacy.

**[T] Real creaturely goodness.** ST I.6.4 says creatures are good through their own created goodness while dependent upon divine goodness as exemplar, efficient, and final cause. I.15.1 rejects ideas existing outside God as independent explanatory entities. I.44.2 brings primary matter itself within creation; I.44.3 locates exemplarity in divine wisdom, while allowing subordinate exemplars within creation. **[C]** This excludes independent Platonic Forms as ultimate co-sources, not every created universal, mathematical object, or secondary exemplar; those require further ontological decisions.

**[T] Multiplicity without acquired divine images.** [ST I.15.2](https://www.newadvent.org/summa/1015.htm) distinguishes the objects understood from the forms by which understanding is actualized. Many ideas are the divine essence understood as variously imitable; they do not form God through multiple acquired cognitive images. Replies 3–4 locate the relevant ideal comparisons in divine understanding, not in creaturely effects as causes of God's eternal knowledge. **[R]** This supplies a disciplined precursor to distinguishing one intrinsic actuality from multiple object-relative determinations. It does not justify identifying all such distinctions with merely arbitrary human descriptions.

**[T] Mixed relations.** [ST I.13.7](https://www.newadvent.org/summa/1013.htm) distinguishes relations real at both termini, relations of reason at both, and a relation real on one side only. Creatures are really related to God; God's ad-extra relative denomination introduces no change or acquired relational accident in God. Reply 5 insists that divine lordship is real because creaturely subjection is real. [I.45.3](https://www.newadvent.org/summa/1045.htm) applies this distinction to creation: passive creation is a real creaturely relation; active creation names divine action with a relation of reason to the creature.

**[C] Formalization safeguard:** a true binary proposition can concern both relata without an intrinsic accident being added to both. “Real in the creature” concerns how the relation is grounded, not whether its inverse sentence is true. This should be called an interpretation of medieval mixed relations, not claimed to be Aquinas's theory of modern abstract relational facts. Do not generalize ad-extra non-acquisition into denial of real divine personal relations: I.15.2 ad4 explicitly contrasts ideal relations with relations distinguishing the Persons.

**[T] Non-rivalry requires secondary causes.** [ST I.105.5](https://www.newadvent.org/summa/1105.htm) directly rejects the claim that created powers effect nothing while God alone does everything. The creature has its proper operation; reply 2 allows the same action to proceed from primary and secondary agents of different orders. **[C]** Total dependence without identity remains compatible with occasionalism unless creaturely efficacy is added. Source-caused capacities and their genuine exercise are needed for strong noncompetitive causality.

**[T] Freedom includes will and an unnecessary means.** [ST I.19.3](https://www.newadvent.org/summa/1019.htm) distinguishes absolute necessity from necessity by supposition. God necessarily wills divine goodness; finite goods are not required for that goodness and add no perfection. Their willing is not absolutely necessary; ad5 identifies God's self-determining will. **[C]** Non-exhaustion alone does not supply this result. An inexhaustible source might necessarily produce this non-exhaustive world. To infer contingency, add admissible alternatives and a mode of communication not necessitated by intrinsic fullness; to infer *freedom*, add intentional self-determination. Contemporary possible-world consistency is a constructive task beyond quoting I.19.3.

## 2. Scotus: indispensable resistance to homogenization

**[L] Primary loci to inspect:** *Ordinatio* I d.3 p.1 qq.1–2, on the concept of being and natural knowledge of God; I d.8 p.1 q.3, on univocity and genus; I d.8 p.1 q.4, on simplicity and formally distinct divine perfections; *Lectura* I d.39 qq.1–5, on divine foreknowledge and contingency. Use the critical Vatican editions for the *Ordinatio* and *Lectura*. These loci are specific research leads, not passages verified here. [Stanford's Scotus article](https://plato.stanford.edu/entries/duns-scotus/) is a specialist entry point; it was blocked.

**[S] Verified secondary findings:** the archived SEP article identifies *Ordinatio* I d.3 p.1 qq.1–2 nn.26–55 for univocal predication and describes infinite being as an intrinsic, positive mode. It quotes I d.1 p.1 qq.1–2 n.142 on a thing's own intrinsic degree of finite or infinite perfection. Its argument explicitly denies that simplicity alone entails infinity. This is an indirect citation; the primary passage remains unconsulted. The article advocates a strong voluntarist interpretation of Scotus and libertarian alternatives at the moment of choice; use it as one interpretation rather than consensus.

**[L] Further interpretive stakes to verify:** Scotus's univocal concept of being need not turn being into a genus, since finite and infinite are intrinsic modes rather than species differentiated by something outside being. Therefore “no common genus” does not adjudicate the Aquinas–Scotus disagreement about semantic univocity. Nor should formal nonidentity of divine perfections be treated as partition into independently existing things. A core excluding constituents can remain compatible with a Scotist account; a core denying every intrinsic formal distinction cannot be presented as neutral between the schools.

**[C] Retrieval proposed for testing:** distinguish intrinsic actuality, the intended object of an action, and its contingent effect. One act's relation to multiple objects need not mean a succession of acquired acts; neither does necessity of the act immediately establish necessity of each effect. But calling the effect contingent supplies no explanation unless a model demonstrates how that contingency is consistent with the chosen identity, simplicity, and modality principles. If the same intrinsic act entails one world under every admissible circumstance, the modal-collapse objection remains. Do not harmonize it away by alternating meanings of “act.”

**[L] Specialist reading priorities:** Richard Cross, *Duns Scotus* (Oxford University Press, 1999), and *Duns Scotus on God* (Ashgate, 2005); Thomas Williams, ed., *The Cambridge Companion to Duns Scotus* (Cambridge University Press, 2003); Antonie Vos and collaborators, *John Duns Scotus: Contingency and Freedom, Lectura I 39* (Kluwer, 1994). They are not evidence consulted here, and their interpretations of modal structure must be compared, not merged by fiat.

## 3. Przywara: articulate an interval without inventing a metric

**[L] Primary source:** *Analogia Entis: Metaphysics—Original Structure and Universal Rhythm*, trans. John R. Betz and David Bentley Hart (Eerdmans, 2014), especially its original-structure and creaturely-rhythm analyses; [publisher record](https://www.eerdmans.com/9780802868596/analogia-entis/) was blocked. Betz's introductory historical and philosophical study in that edition is a specialist guide, not the only permissible interpretation.

**[C] Structural use, pending textual comparison:** creaturely likeness is inseparable from an irreducible difference of mode; greater dissimilarity guards against converting divine excess into a magnified creature. “Greater” here must not become a numerical comparison between two quantities without an independently supplied metric. Neither does it mean that similarities are false. Przywara can provide disciplined constraints on the articulation of already-established dependence and analogy. To *generate* the grammar, the reconstruction must still show why causal dependence entails manifestation under its explicit adequacy principle. A slogan about polarity supplies no missing bridge.

**[C] A good synthetic retrieval leaves open:** Aquinas versus Scotus on predication; accounts of divine formal distinctions; and traditions' differing explanations of creaturely-divine presence. The interval is genuinely ontological distinction, not an extra spatial object wedged between God and creatures.

## 4. Newman: a provisional development test, not retrospective attribution

**[T] Chapter V's seven notes are:** preservation of type (§I), continuity of principles (§II), power of assimilation (§III), logical sequence (§IV), anticipation of its future (§V), conservative action upon its past (§VI), and chronic vigour (§VII). The opening §4 calls them notes “of varying cogency, independence and applicability.” §IV explicitly distinguishes conscious deduction from developments that first arise through reflection and are later organized logically. §VI says development should illustrate rather than disturb prior achievements. These are historical-discriminatory notes, not an axiomatic completeness theorem.

**[C] Analogical assessment for this project:** preserve the Creator–creature distinction and real created goodness; conserve non-dependence and non-acquisition; assimilate divine-ideas and recipient-mode insights without making the ideas external gods; display an explicit inferential sequence; identify antecedents without ascribing the synthesis to them; retain earlier explanatory achievements while recording disagreements. Deletion models, category checks, and modal consistency checks are new procedures that can serve the logical-sequence and conservation aims.

A new project cannot already demonstrate Newman's seventh note of chronic vigour. Present explanatory fruitfulness and successful stress tests as a provisional analogue, not as demonstrated historical endurance. The user is adopting Newman analogically; passing the assessment would neither prove all premises nor confer ecclesial authority on the resulting theory. Genuine tensions cannot be harmonized by calling their reversal a development.

## 5. Minimality decisions these witnesses support

**[C] Recommend a layered basis:** explanatory dependence distinct from identity; a separate positive-character/perfection language; causal-adequacy bridge; distinction between intrinsic constitution and relational denomination; a finite/limited-mode predicate whose semantics are independently constrained. Then add explicitly divine axioms for universal sustaining source, non-constitution and non-acquisition, infinitude, and the relevant simplicity. Add free intentional communication only when deriving contingent creation; add efficacy of secondary causes when excluding occasionalism.

Actuality can be the actual-world quantifier's domain restriction instead of a primitive predicate, but that saves typography rather than explaining actuality. Reception can be defined as actual possession through explanatory production; it should not mean a pre-existing empty receiver subsequently filled, since creation includes the receiver. Participation can be defined as that derivative possession with warranted causal likeness. Non-exhaustion should be derived from finite reception plus a genuinely unlimited source, not built into reception. Mere irreflexive dependence does not forbid a cause being a constituent of its effect. Absence of a common genus must be established separately from mere nonidentity.

The explanatory stopping point is thus not an innocent three-word formula. Each proposed compression must preserve these distinctions or disclose which metaphysical axiom has been folded into its relation's semantics.

**[L] Aquinas specialist priorities, not consulted:** Rudi A. te Velde, *Participation and Substantiality in Thomas Aquinas* (Brill, 1995); John F. Wippel, *The Metaphysical Thought of Thomas Aquinas* (Catholic University of America Press, 2000); Fran O'Rourke, *Pseudo-Dionysius and the Metaphysics of Aquinas* (Brill, 1992; later Notre Dame edition); Gregory P. Rocca, *Speaking the Incomprehensible God* (Catholic University of America Press, 2004). Te Velde/Wippel can challenge reductions of participation to a mere external relation; O'Rourke can test Dionysian continuity; Rocca can separate causal naming from predicative equivalence. These are questions for those works, not findings attributed to unread pages.
