Question 13

How does God know this actual world without receiving cognitive completion from it?

Knowledge of possible worlds must be distinguished from knowledge of this actual creation.

In this question

The short answer

God's knowledge of every possibility does not alone explain knowledge of what actually occurs. Productive knowledge offers an account of effects through awareness of an actual efficacious intention. It requires that the intention and its efficacy be adequately known. Free secondary acts require a further cognitive account because sustaining an agent is not intending everything that agent chooses. Truth's dependence on an actual creature also differs from the creature's supplying actuality to divine cognition.

Knowing through an actual action

An intelligent source can know an intended effect through adequate knowledge of its own actual exercise and what that exercise unfailingly produces. This is the proposed structure of productive knowledge. Aquinas's discussion of divine knowledge as cause, joined to willing, supplies a historical resource. Our use requires stating the cognitive conditions rather than equating causation with awareness.

The source must know which intention is actual, understand its effective scope, and grasp what follows from its exercise. Knowing every possible plan leaves the first condition unanswered. Nor can an effect's eventual occurrence retrospectively supply the awareness that the proposal attributes to God. Deliberate noncreation tests the account without an actual effect to inspect.

The surrounding argument explicitly says that an intelligible form alone does not determine an effect without willing. Productive knowledge is Aquinas's account here; citing it does not independently explain actual-world knowledge or settle the harder case of free creaturely action.

Now it is manifest that God causes things by His intellect, since His being is His act of understanding; and hence His knowledge must be the cause of things, in so far as His will is joined to it.

Truth and cognitive actuality

A true judgment that a creature exists requires that creature's existence. Without the creature, that judgment would be false. It does not follow that the creature produces a new cognitive perfection in every knower. The condition making a claim true and the cause actualizing cognition are distinct explanatory relations, even when they coincide in ordinary perception.

This distinction also matters across alternative situations. If no creatures existed, truths about actual creatures would differ. An account committed to intrinsic invariance must explain how divine knowledge remains determinate and factive across those differences. Calling it non-receptive states a condition of success; it does not supply the positive relation by which actual content is known.

The harder case of creaturely freedom

A creature may exercise a received power through its own intention. God's sustaining that power does not, simply as such, make every chosen intention God's intention. Productive knowledge of divinely specified effects therefore cannot automatically stand in for knowledge of all free decisions, omissions, and moral defects. Permission and authorship require different accounts.

We propose that divine intellect knows creaturely actuality without acquiring representations caused by it. This requires an independent account of cognitive presence to actual choices. Foreknowledge adds another burden: access to temporal actuality without reducing free choices to necessary events. Catholic omniscience gives the theological commitment; the proposed metaphysics must explain the relevant access and warrant.

From possible content to knowledge of an actual effect

Knowing every possible design does not tell an architect which design is being executed. Even knowing that any executed design would succeed leaves the actual undertaking unspecified. The divine proposal likewise needs three distinguishable truths: God understands W as possible, God actually intends W, and God is reflectively aware of that actual intention and its efficacy. These need not be successive thoughts or separate cognitive parts. Their distinction identifies the information an explanation must preserve. Possible content alone cannot supply awareness of actual intention.

Given those conditions, knowledge of an intended effect has a definite explanatory route. God knows the actual exercise as God's own, knows that its efficacy entails the effect, and therefore knows the effect without learning it from the creature. An ordinary maker's awareness of an action illustrates why knowing need not always begin by inspecting a finished product, although finite mistakes and intervening causes limit the comparison. In the no-creation case, self-awareness concerns voluntary refraining: God knows that no creature is produced through an actual creative intention. This cannot be derived from an inventory of possibilities or from an external effect.

How awareness of acting can warrant knowledge of an effect

The productive account now has a positive order. Possible content is understood; an actual undertaking is directly present through the agent's self-manifesting exercise; and its effective scope is known through adequate knowledge of the power being exercised. Within that scope the intended effect is known as what this exercise unfailingly produces. These are explanatory distinctions within one operation, not three successive divine judgments. Aquinas's discussion of productive knowledge explicitly requires willing as well as intelligible form (Summa theologiae I, q.14, a.8).

The order avoids a vicious circle only because awareness of the undertaking has its own proposed basis. It does not begin with the observed world and reconstruct an intention, then cite that intention to establish the world. Practical awareness makes the actual exercise present as the source's own; independently known efficacy warrants its effect. Nor is it enough to say that whatever God thinks is happening must happen. An agent can understand a plan without undertaking it, and a finite intention can fail. The account needs actual exercise, adequate reflexivity, and known efficacy together.

The creature makes many propositions about itself true. That truthmaking dependence does not mean that it actualizes God's cognitive power. On the invariant model, the full fact of knowing this actual effect involves the effect, while the source's knowing is exercised productively rather than acquired by inspection. The additional bridge is that direct awareness can embrace the complete action without a varying intrinsic representation. That bridge is motivated by practical self-awareness and the proposed ontology of exercise; distinguishing truthmaking from cognitive actualization alone would not supply it.

Free secondary acts remain a separate question. Knowing what God efficaciously specifies does not identify every choice made through a sustained creaturely power. It especially does not make a wrongful intention God's intention. Aquinas offers the further resource of eternal presence to contingent acts as actual in themselves (q.14, a.13). But locating an event within eternity does not, by itself, explain adequate cognitive access to its freely settled content. The present agency account therefore advances knowledge of God's own undertaking and its specified effects. Nonreceptive foreknowledge of every free creaturely exercise still requires its own defense.

Where productive knowledge reaches its limit

This route is conditional on knowing the actual intention. If intrinsic actuality is invariant, appealing to self-knowledge of that actuality alone leaves world-specific direction unexplained. The model must allow God's awareness to encompass the complete source-founded exercise without acquiring a new intrinsic representation. It also distinguishes a creature's making a proposition true from a creature's actualizing God's intellect. Those are different dependence relations. Their distinction removes an objection to nonreceptive knowledge; it does not independently establish the positive cognitive access.

A freely acting creature makes the remaining issue sharper. Sustaining a person's power does not by itself mean specifying the person's choice. Productive awareness of what God efficaciously intends therefore cannot simply be extended to every wrongful intention as though God authored it. A proposed further route is immediate intellectual presence to the actual creaturely exercise: its particular content is known without a representation received from it. Causal intimacy makes such access worth investigating, but causal intimacy is not already knowledge. The account still owes a bridge to factive awareness of the freely settled choice and, for foreknowledge, its temporal actuality. Omniscience remains the theological commitment; this extension does not claim a completed philosophical explanation of nonreceptive knowledge of free secondary acts.

The strongest objection

If what God knows differs with the world, must God's own actuality differ too?

That follows only if every difference in known actual content requires a different intrinsic cognitive actualizer. Our proposal contests that requirement while retaining factive knowledge. It must explain how this actuality is cognitively present without being a cause of divine completion. Distinguishing truthmaking from cognitive actualization removes a conflation, but the positive account of knowledge remains indispensable.

What follows

  • Omniscience is received in Catholic theology. Productive knowledge and non-receptive cognitive presence are distinct philosophical proposals with specific conditions that must be defended.
