Philosophical TermLatin (medieval scholastic philosophical Latin)

ante rem

//ˈan.te rem/ (Classical Latin); commonly /ˌænti ˈrɛm/ in English usage/
Literally: "before the thing"

From Latin preposition "ante" (before, in front of, prior to) + accusative singular of "rēs" (thing, matter, fact, event, reality). In scholastic Latin, the phrase becomes a fixed technical locution contrasting with "in re" (in the thing) and "post rem" (after the thing), used to articulate modes of being for universals.

Translation Difficulties

The Latin preposition "ante" encodes both temporal and logical priority, and "rēs" ranges from concrete objects to facts and states of affairs. Rendering "ante rem" simply as "before the thing" can misleadingly suggest chronological existence rather than ontological or logical priority. English phrases like "ante rem universals" or "universals existing prior to things" risk importing Platonizing connotations that exceed some medieval uses, while more neutral options (e.g., "independently of things") may understate the strong realist commitment that universals have a genuine mode of being distinct from, and prior to, their instantiation in particulars.

Evolution of Meaning
Pre-Philosophical

In classical Latin, the sequence "ante rem" appears in non-technical contexts simply to indicate temporal or spatial priority (e.g., "ante rem facere"—to do something before the matter at hand), without any ontological or metaphysical import. It functions as a common prepositional phrase rather than a fixed term of art.

Philosophical

Within medieval scholasticism, particularly from the 12th century onward, "ante rem" becomes part of the canonical trichotomy of the modes of being of universals: ante rem (before the thing, in the divine intellect or a separate realm), in re (in the thing, as instantiated in particulars), and post rem (after the thing, as abstracted in the human intellect). It serves to classify strong realist positions—those positing a genuine prior existence of universals—and to frame debates in the problem of universals and in theological discussions of divine ideas.

Modern

In modern and contemporary philosophy, "ante rem" is primarily used in English-language metaphysics as a label for one kind of realism: the view that universals, sets, or mathematical objects exist independently of their instances or of the empirical world. The term often appears in technical contrasts—"ante rem realism" vs. "in re realism" or nominalism—and in philosophy of mathematics, where Platonist approaches are sometimes described as ante rem positions about numbers, sets, or structures. Outside specialist literature, it is rarely used and is often paraphrased as "Platonic" or "transcendent" realism.

1. Introduction

The expression ante rem designates a particular way of understanding the existence of universals or abstract entities: as in some sense prior to and independent of the individual things that instantiate them. In the history of philosophy, it functions both as a technical label within medieval Latin scholasticism and, more recently, as a typifying term in analytic metaphysics and philosophy of mathematics.

Within medieval debates on the problem of universals, ante rem typically appears as one element of a triad: ante rem, in re, and post rem. This triad classifies different purported “modes of being” for universals. The ante rem mode is associated with strong forms of realism, according to which common natures or forms possess a real status that does not depend on being instantiated in particular things or conceived by finite minds.

Historically, the notion of ante rem universals has been linked—sometimes directly, sometimes by retrospective interpretation—to Platonism, where Forms are regarded as paradigms of things, and to various strands of scholastic realism, especially discussions of divine ideas and exemplarism. Figures such as Thomas Aquinas and Duns Scotus develop nuanced accounts in which universals have some sort of being in the divine intellect, often described as an ante rem existence. By contrast, nominalists and conceptualists argue that such universals either reduce to mental or linguistic items or should not be posited at all.

In contemporary philosophy, “ante rem realism” is widely used to denote views that posit abstract objects—universals, sets, numbers, or structures—which exist independently of empirical reality and of our thought. It is often contrasted with immanent realism (or in re realism), which ties universals more closely to their instances, and with nominalism, which denies mind- and world-independent universals altogether.

The sections that follow examine, in turn, the linguistic origins of the phrase, its pre‑philosophical and scholastic uses, its role in medieval and contemporary debates about universals, and its applications in areas such as the philosophy of mathematics and structuralism, while also surveying critical responses and interpretive difficulties surrounding the term.

2. Etymology and Linguistic Origins

The phrase ante rem derives from classical Latin, combining the preposition ante with the accusative singular rem of rēs.

Components of the Phrase

ElementBasic Latin MeaningRange of Senses
ante“before,” “in front of”Temporal priority (“before in time”), spatial position (“in front of”), and, by extension, logical or rank priority (“prior in order/importance”)
rēs (acc. rem)“thing,” “matter,” “event,” “fact,” “affair,” “reality”Concrete object, situation, legal case, public matter, or general “state of affairs”

In non-technical Latin, ante rem could mean before the matter, before the event, or in advance of the thing under discussion. The phrase did not initially have metaphysical implications.

Semantic Development

Medieval scholastic authors refunctionalized the everyday phrase into a fixed technical locution. In philosophical Latin, ante rem came to mark a specific mode of being of universals—one that is:

  • Ontologically “prior” to particular things, in the sense of explanatory or metaphysical dependence.
  • Often located in the divine intellect (as in many Christian scholastics) or in a separate intelligible realm (as in Latin receptions of Platonism).

This adaptation relied on the flexibility of ante, which could signify not only temporal succession but also logical or ontological priority. Similarly, the breadth of rēs allowed it to stand generically for any item of reality, including individual substances and their properties.

Relation to Companion Expressions

As scholastic technical vocabulary stabilized, ante rem was systematically paired with:

  • in re – “in the thing,” indicating existence in particulars.
  • post rem – “after the thing,” indicating existence in the intellect by abstraction.

These three expressions crystallized into a standard taxonomy for discussing universals’ modes of being.

The later adoption of ante rem into modern European languages (e.g., “ante rem universals,” “ante rem realism”) largely preserves this medieval technical sense, though often with increased association to Platonist or abstract-object metaphysics.

3. Pre-Philosophical Usage of “ante rem”

Before acquiring a technical metaphysical meaning, ante rem functioned in Latin as a common prepositional phrase with straightforward temporal or spatial import.

Ordinary Latin Contexts

In classical and later non-scholastic Latin, the phrase appears in contexts such as:

  • Legal and political discourse:

    ante rem iudicandam – before the matter is judged

  • Narrative or historical writing:

    haec dixit ante rem gestam – he said this before the event took place

  • Administrative or practical contexts:

    omnia paravit ante rem – he prepared everything before the business at hand

Here ante rem simply modifies a verb to indicate that some action occurs prior to some event, case, or affair denoted by rēs. The phrase does not, in these uses, imply anything about kinds, universals, or abstract entities.

Lack of Technical Ontological Sense

Pre-philosophical uses generally lack:

  • Any contrast with in re or post rem.
  • Any suggestion of separate realms of being.
  • Any explicit appeal to logical rather than chronological priority.

Insofar as logical or priority readings might be inferred, they tend to be contextual and rhetorical, not systematic. A Roman historian might use ante rem to suggest that some decision was taken in anticipation of a later event, but this remains within a practical, not metaphysical, horizon.

Transition Toward Technical Usage

The transformation of ante rem into a metaphysical term occurs in medieval scholastic Latin. Commentators on Aristotle and Porphyry sought concise formulas to classify different “ways of being” for universals. The already familiar phrase ante rem could naturally be repurposed to indicate a form of priority of universals relative to particulars.

The emergence of the triadic schema (ante rem / in re / post rem) thus rests on:

  • The linguistic availability of a flexible prepositional phrase.
  • The conceptual need to distinguish several modes of universals’ existence.

Pre-scholastic Latin provides the raw material, but the philosophical meaning is a later, specialized development layered onto essentially non-technical everyday usage.

4. The Scholastic Triad: Ante Rem, In Re, Post Rem

Within medieval scholasticism, ante rem, in re, and post rem form a canonical triad for classifying the modes of being of universals. The triad structures debates on how universals relate to individual things and to the intellect.

Basic Schema

ModeLiteral MeaningLocation of the UniversalTypical Theoretical Use
ante rembefore the thingIn a prior realm or in the divine intellectStrong realism / exemplarism
in rein the thingAs instantiated in particular substancesImmanent or moderate realism
post remafter the thingIn the human intellect as an abstracted conceptConceptualist and cognitive accounts

The triad does not always track distinct entities; many authors treat these as different respects or considerations of one and the same nature.

Function in Medieval Debates

Commentators on Porphyry’s Isagoge and Aristotle’s logical works employed the triad to frame questions such as:

  • Do universals exist prior to individuals (as exemplars)?
  • Are universals found in individual things as their forms or essences?
  • Are universals only mental constructs formed after encountering individuals?

By assigning various schools to positions within this triad, scholastics could:

  • Classify Platonists as privileging ante rem universals.
  • Identify Aristotelians (in some readings) with in re universals.
  • Associate nominalists and some conceptualists with post rem universals exclusively.

Interdependence and Overlap

Many scholastics maintained that these modes are not mutually exclusive. For instance:

  • Some Thomists hold that the same nature can be:
    • In the divine intellect ante rem as an idea divina.
    • In particulars in re as their substantial form.
    • In the human mind post rem as an abstracted concept.

Others, particularly critics of strong realism, argue that treating ante rem and post rem modes as genuinely distinct ontological statuses is unnecessary or problematic.

The triad thus serves as a heuristic framework: it summarizes positions while also providing a shared vocabulary for more fine-grained disagreements about universals’ dependence, location, and mode of being.

5. Ante Rem in Medieval Realism

Within medieval realism about universals, ante rem came to mark positions that attribute to universals some mode of existence independent of and prior to their instantiated presence in particulars.

Realist Motivations

Realist arguments for an ante rem dimension often appeal to:

  • The apparent objectivity and stability of scientific definitions and species.
  • The need for exemplary causes or patterns by which God creates and orders the world.
  • The idea that multiple individuals share a common nature that seems more than a mere name.

Medieval realists typically distinguish between:

AspectDescription
Common natureWhat is the same in all individuals of a species (e.g., humanity in Socrates, Plato).
Mode of beingThe way this nature exists: as exemplar in God (ante rem), as form in individuals (in re), or as concept in the mind (post rem).

Exemplarist Ante Rem Realism

A widespread pattern, found among many theologians, holds that universals exist ante rem as divine ideas (ideae divinae). On this view:

  • God conceives all possible creatures under universal concepts.
  • These divine ideas function as exemplars (exemplaria) that ground:
    • The intelligibility of the world.
    • The truth of universal propositions.
  • The universals’ ante rem existence is thus primarily theological and intellectual, not a separate “realm” in competition with God.

Variations Among Realists

Medieval realists articulated different strengths of ante rem commitment:

  • Some authors (especially in Augustinian traditions) push toward a robust exemplarism, emphasizing the distinctness and multiplicity of divine ideas corresponding to universals.
  • Aquinas articulates a restricted ante rem realism, in which universals exist in God’s intellect but are not multiplied into a distinct “realm” of Forms independent of God.
  • Scotus develops the notion of natura communis with a more articulated metaphysical status, which some interpret as a uniquely refined ante rem position.

In all these cases, ante rem realism remains bound up with a dual concern: explaining the objectivity of universal predication and classification, and integrating that explanation into a theological framework grounded in the divine intellect.

6. Platonism and the Ante Rem Model of Universals

Although the Latin phrase ante rem does not appear in Plato, medieval and modern authors frequently interpret Platonism as endorsing a paradigm case of ante rem universals. The Forms are taken to exemplify a mode of being for universals that is independent of and prior to sensible particulars.

Platonic Forms as Ante Rem Universals (Retrospective Reading)

On a commonly presented model:

  • Forms (e.g., the Form of Beauty, Justice, Triangle) are:
    • Separate from sensible things.
    • Unchanging and perfect.
    • Causally and explanatorily prior to particulars that participate in them.
  • Particulars are F (beautiful, just, triangular) by participating in or imitating the relevant Form.

From a scholastic standpoint, this is easily rendered as: universals exist ante rem in an intelligible realm, with sensible things deriving their properties from these pre-existing universals.

Textual Bases and Interpretive Nuances

Passages often cited in this connection include:

“We are in the habit of positing a single Form in connection with each of the many things to which we apply the same name.”

— Plato, Phaedo 74b–c

“The things that are seen are in flux, but the Forms are unseen and unchanging.”

— Plato, Republic 507b–509d (paraphrased emphasis)

Interpreters disagree on how directly these texts support a full-fledged theory of universals in the later scholastic sense. Some emphasize Plato’s epistemological and ethical interests over systematic ontology; others argue that the Forms function as ante rem universals in all but name.

Medieval Reception

Medieval thinkers accessed Plato largely through secondary sources (e.g., Augustine, the Neoplatonists, and Latin doxographical traditions). Within these receptions:

  • “Platonic” positions are often characterized as positing universals outside things (universalia extra res).
  • This is then equated with universalia ante rem, contrasting with Aristotelian in re realism.
TraditionAttributed Status of UniversalsRelation to Ante Rem
“Platonic” (in medieval accounts)Forms or ideas existing separately from particularsParadigm of ante rem universals
Aristotelian (standard reading)Forms existing in substances as their essencesModel for in re universals

While this schematization simplifies Plato’s own thought, it plays a central role in shaping the ante rem model: a realm of separate universals, ontologically and epistemically prior to the changing world of particulars.

7. Aquinas, Divine Ideas, and Restricted Ante Rem Realism

Thomas Aquinas offers a nuanced account in which divine ideas provide a limited sense in which universals may be said to exist ante rem, while he resists positing a separate realm of Forms in the created order.

Divine Ideas as Exemplars

In Summa Theologiae I, q. 15 and related texts, Aquinas argues that:

  • God knows creatures by knowing His own essence, which is the exemplar of all things.
  • From our perspective, this knowledge can be described in terms of many ideas (ideae), corresponding to the different ways creatures imitate the divine essence.

“In God there are ideas, that is, the forms of things existing apart from the things themselves.”

— Thomas Aquinas, ST I, q. 15, a. 3 (paraphrased)

These ideas divinae function as exemplars and are sometimes characterized as universals existing before things, since they ground the possibility and intelligibility of created natures.

Restricted Ante Rem Status

Aquinas’s position is often described as a restricted or qualified ante rem realism because:

  • The ideas are not autonomous entities in a separate ontological realm; they are identical with the divine essence, differing only according to our conception.
  • Universals do not exist as separate forms outside God and outside particulars; instead, they exist:
    • In God’s intellect as exemplars (ante rem).
    • In creatures as their essences or forms (in re).
    • In the human mind as abstracted concepts (post rem).
ModeAquinas’s Interpretation of Universals
Ante remAs divine ideas in God’s intellect; not distinct entities from God.
In reAs the forms or essences of created substances.
Post remAs intelligible species or concepts in the human intellect.

Distance from “Platonic” Ante Rem Realism

Aquinas criticizes what he portrays as Platonic realism for positing universals separate from singulars within the created order. He insists that:

  • In creatures, there is no universal apart from the singular; universality arises in the intellect.
  • Yet, because God’s knowledge is archetypal, there is a sense in which the forms of things preexist in Deo, thus warranting the ante rem terminology in a limited, theologically framed way.

Consequently, Aquinas provides an influential model in which ante rem universals are theologically anchored and metaphysically subordinated to the doctrine of divine simplicity, rather than constituting an independent domain of abstract entities.

8. Duns Scotus and the Common Nature

John Duns Scotus develops a distinctive realism centered on the notion of natura communis (common nature), which many interpreters regard as a sophisticated form of ante rem thinking.

The Common Nature

Scotus introduces the idea that, for a given species (e.g., humanity), there is a nature that is:

  • Common to all its individuals.
  • Neither universal nor singular in itself, but capable of being:
    • Individuated in singulars via an additional principle (e.g., haecceitas or thisness).
    • Considered as universal in the intellect when predicated of many.

“The nature as it is in itself is neither one nor many, neither universal nor singular.”

— Duns Scotus, Ordinatio II, d. 3, pars 1, q. 5 (paraphrased)

Mode of Being of the Common Nature

Scotus distinguishes formalities or aspects within reality and in thought. The natura communis:

  • Has a formal reality that is not reducible to mere mental fiction.
  • Exists in individuals in re, but in such a way that its commonness is not wholly dependent on the intellect.
  • Is exemplarily present in the divine intellect, which contains the most perfect cognition of this nature prior to its multiplication in individuals.

This structure leads some commentators to interpret Scotus as affirming an ante rem status for common natures, though Scotus himself emphasizes their immanent existence in individuals.

Relation to Ante Rem and In Re

AspectScotus’s Position
Ante rem (in God)Common natures as objects of divine knowledge, serving as exemplars.
In re (in creatures)The same nature formally present in multiple individuals, individuated by haecceitas.
Post rem (in intellect)The nature considered as universal when predicated of many.

Unlike simpler schemas that locate universals either in a separate realm or only in thought, Scotus’s account allows the same formal content (the nature) to underlie all three modes.

Interpretive Debates

Scholars disagree on how to classify Scotus:

  • Some describe him as a moderate realist placing primary emphasis on in re existence.
  • Others view his emphasis on the formal distinction and common nature as introducing a robustly ante rem-like dimension, especially in the context of divine ideas.

What is relatively uncontroversial is that Scotus’s doctrine of natura communis offers one of the most intricate medieval frameworks for understanding how something can be common and yet really present in distinct individuals without collapsing into mere conceptualism.

9. Nominalist and Conceptualist Critiques of Ante Rem Universals

Nominalists and conceptualists challenge the need for, or coherence of, ante rem universals, proposing alternative explanations for generality and predication.

Nominalist Rejection of Extra-Mental Universals

Figures like William of Ockham argue that:

  • There are no real universals outside the mind, either ante rem or in re.
  • Only individuals exist extra-mentally; universals are either:
    • Names applied to many things (nomina).
    • Mental signs that naturally signify many individuals.

“No universal is a thing existing outside the soul.”

— William of Ockham, Summa Logicae I, c. 14 (paraphrased)

From this standpoint, positing ante rem universals is seen as ontologically extravagant and unmotivated, introducing entities beyond the individual substances already acknowledged.

Conceptualist Accounts

Conceptualists similarly deny extra-mental universals but emphasize the role of the intellect:

  • Universality is a feature of concepts, not of things.
  • When we form a universal concept (e.g., humanity), the mind abstracts common features from individuals and forms a representation that can apply to many.

While conceptualists may accept post rem universals (in the mind), they regard ante rem talk as figurative or as reducible to God’s knowledge considered under a psychological description.

Critiques of Ante Rem Realism

Nominalist and conceptualist criticisms typically include:

CritiqueDescription
RedundancyAnte rem universals are claimed to add no explanatory power beyond individuals and mental/language practices.
Causal inefficacyAbstract entities “before things” seem causally inert, raising doubts about their relevance to explaining change or action.
Epistemic accessHow finite minds could know or refer to a separate realm of universals is regarded as obscure.
Multiplicity of entitiesFor each universal, an additional ante rem entity appears to be posited, leading to an inflated ontology.

In theological contexts, some critics reinterpret divine ideas not as distinct universals but as God’s single act of self-knowledge, thereby avoiding commitment to a multiplicity of ante rem universals.

Collectively, these critiques press realists to clarify the mode of being, causal role, and epistemic availability of any alleged ante rem universals and to justify their necessity over leaner ontological accounts.

10. Ante Rem Realism in Contemporary Metaphysics

In contemporary analytic metaphysics, ante rem realism generally designates positions that maintain the existence of universals or other abstract entities independently of their instances. It is often contrasted with immanent (in re) realism and nominalism.

Core Commitments

Ante rem realists typically hold that:

  • Universals (properties, relations, kinds) or mathematical entities:
    • Exist whether or not they are instantiated.
    • Are wholly abstract, lacking spatiotemporal location and causal powers (on many accounts).
  • Particulars instantiate or exemplify these universals, but the universals themselves do not metaphysically depend on being instantiated.
PositionStatus of UniversalsDependence on Instances
Ante rem realismAbstract entities existing independentlyNot dependent on instantiation
In re realismUniversals exist only as instantiatedDependent on instances
NominalismNo mind-independent universalsOnly individuals and/or linguistic/mental devices

Representative Views

Contemporary discussions often refer to:

  • Platonist property theorists, who affirm a realm of abstract properties and relations.
  • Set-theoretic Platonists, who treat sets as ante rem entities in the foundations of mathematics.
  • Structuralist views in the philosophy of mathematics that treat structures as abstract entities (see Section 11).

Philosophers such as Michael Loux and E. J. Lowe employ the label “ante rem realism” to organize the taxonomy of theories of universals and abstract objects, particularly in contrast to D. M. Armstrong’s immanent realism, which ties universals essentially to their instances.

Arguments and Challenges

Common arguments in favor of ante rem realism include:

  • Explanatory: Abstract properties and relations are said to offer unified accounts of similarity, lawhood, and modality.
  • Semantic: Reference to abstract entities allegedly best makes sense of the truth of general and mathematical statements.
  • Indispensability: Certain scientific and mathematical practices appear to presuppose entities that function as ante rem universals.

Critics raise concerns analogous to medieval nominalist objections:

  • The epistemic problem: How can we know causally inert, non-spatiotemporal entities?
  • The individuation problem: How are universals themselves distinguished and identified?
  • The ontological cost: Whether the explanatory benefits justify adding a domain of abstract objects.

Contemporary ante rem realism thus rearticulates many classical themes in a new idiom, focusing on properties, sets, and mathematical structures rather than on species and genera in the scholastic sense.

11. Ante Rem in the Philosophy of Mathematics and Structure

In the philosophy of mathematics, “ante rem” is frequently used to characterize Platonist and certain structuralist positions according to which mathematical objects or structures exist independently of physical systems and of human thought.

Mathematical Platonism as Ante Rem Realism

Mathematical Platonists maintain that:

  • Entities such as numbers, sets, and functions exist as abstract objects.
  • Their existence and properties are independent of whether any physical system exemplifies them or whether they are conceived by mathematicians.

On this view, structures like the natural number sequence or the real line have a determinate existence ante rem, with concrete systems (e.g., collections of physical objects) merely instantiating these structures.

Structuralism and Ante Rem Structures

Structuralist approaches focus on patterns of relations rather than on independently existing objects. Within structuralism, one can distinguish:

Type of StructuralismStatus of StructureExample of Ante Rem Reading
Ante rem structuralismStructure exists as an abstract entity, independently of any systems instantiating it.The natural number structure exists even if no physical collection realizes it.
In re structuralismStructure exists only as instantiated in particular systems.The structure exists only in physical or set-theoretic systems exhibiting it.
Modal structuralismStructure is understood via possible systems satisfying certain axioms.Uses modal talk rather than explicit ante rem entities.

Ante rem structuralists (e.g., some readings of Stewart Shapiro) interpret structures themselves as abstract universals: any system that exemplifies the Peano axioms instantiates the ante rem structure of the natural numbers.

Epistemological and Ontological Issues

Debates surrounding ante rem views in mathematics center on:

  • Epistemic access: How mathematicians can have knowledge of or reference to remote abstract structures.
  • Identity and indeterminacy: Questions about whether there is a unique structure corresponding to a given theory (e.g., categoricity issues).
  • Dependence and instantiation: Whether mathematical structures require instances or whether their existence is entirely independent of them.

Proponents argue that ante rem structures best account for:

  • The apparent objectivity and necessity of mathematics.
  • The applicability of mathematics to the physical world: physical systems are seen as approximating or instantiating pre-existing abstract structures.

Critics often seek alternatives (e.g., nominalism, in re structuralism, or more deflationary views) that avoid commitment to a robust realm of ante rem mathematical entities while still accommodating mathematical practice.

12. Conceptual Analysis: Priority, Dependence, and Existence

The term ante rem centrally involves notions of priority, dependence, and existence. Philosophical uses of the phrase hinge on how these notions are understood and related.

Types of Priority

“Ante” can signal several kinds of priority:

Type of PriorityCharacterizationRelevance to Ante Rem
TemporalEarlier in timeLess central; often explicitly denied in discussions of eternal universals.
LogicalPrior in order of explanation or implicationUniversals may be said to be logically prior to their instances.
Ontological (metaphysical)More fundamental or independent in beingKey sense in ante rem realism: universals are more fundamental than their instances.

When philosophers describe universals as existing ante rem, they generally invoke logical or ontological priority rather than temporal sequence.

Dependence Relations

A central question is whether particulars depend on universals, or vice versa:

  • In ante rem realism, universals typically do not depend on their instances; they could exist uninstantiated.
  • Particulars, by contrast, are often said to depend on universals for:
    • Their essential nature (what they are).
    • Their similarities to other particulars.

Some immanent realists modify this by allowing mutual dependence or by denying the possibility of uninstantiated universals, thereby resisting a strong ante rem reading.

Modes of Existence

The triad ante rem / in re / post rem can be interpreted as distinguishing modes of existence:

  • Ante rem: Existence as abstract, independent entities (or as ideas in a divine intellect).
  • In re: Existence as forms or properties in particulars.
  • Post rem: Existence as concepts or representations in minds.

Philosophers differ on whether these are genuinely different kinds of being or rather different ways of considering the same thing. For instance:

  • Some scholastics hold that the same nature can be considered under these different modes without multiplicity of entities.
  • Others, especially critics, argue that only post rem (conceptual) universals exist, and ante rem is purely metaphorical.

Conceptual Tensions

The analysis of ante rem raises several conceptual tensions:

  • How to articulate independence without isolating universals from any explanatory relation to particulars.
  • How to reconcile uninstantiated universals with views that tie existence closely to causal roles or empirical grounding.
  • Whether an appeal to logical priority suffices for ante rem realism, or whether a stronger sense of metaphysical priority is required.

These issues shape contemporary and historical debates over the plausibility and exact meaning of ante rem existence.

The notion of ante rem universals stands within a broader network of concepts and theoretical options regarding universals and abstract entities.

ConceptRelation to Ante Rem
Universalia (universals)General items (kinds, properties) whose mode of existence is at issue; ante rem realism is one option among others for their ontological status.
Natura communis (common nature)In Scotus, a nature that can be considered under ante rem, in re, and post rem aspects; often used to articulate an ante rem element.
Forma universalis (universal form)A form that can be instantiated in many; ante rem accounts sometimes treat such forms as existing prior to their instances.
Idea divina (divine idea)In exemplarist theology, often identified with universals ante rem in the divine intellect.

Contrasting Positions on Universals

PositionCore ClaimStance on Ante Rem
Realismus ante remUniversals or abstract entities exist independently of their instances.Affirms ante rem mode as fundamental.
Realismus in re (immanent realism)Universals exist only in particulars, not as separate entities.Denies ante rem realm in the created order; may accept divine ideas in a special sense.
Nominalismus (nominalism)Only individuals exist; universals are names or linguistic devices.Rejects ante rem universals entirely.
Conceptualismus (conceptualism)Universals exist only as concepts in minds.Restricts universals to a post rem mode; ante rem is at most metaphorical.
Platonismus (Platonism)Abstract entities (Forms, numbers, etc.) exist in a separate realm.Often interpreted as a strong ante rem view.

Exemplarism

Exemplarismus posits that created things are patterned on exemplars—often divine ideas—that function as standards or models. This doctrine often incorporates ante rem language:

  • Exemplar causes are prior in being and explanation to their effects.
  • The forms of creatures exist as ideas divinae in the divine intellect before they exist in created things.

Exemplarism thus overlaps with, but is not identical to, full-fledged ante rem realism about universals, since its primary focus is causal and theological rather than purely ontological.

Broader Metaphysical Context

Discussions of ante rem also intersect with:

  • Theories of abstract objects (e.g., numbers, sets).
  • Debates about properties (universals vs. tropes).
  • Accounts of laws of nature and modal realism, where universals or structures may be posited as grounds for lawhood and modality.

Contrasting positions in these areas can often be mapped onto the ante rem / in re / post rem taxonomy, albeit with adaptations to contemporary metaphysical vocabulary.

14. Translation Challenges and Interpretive Pitfalls

Translating and interpreting ante rem involves several difficulties stemming from both Latin semantics and philosophical assumptions.

Temporal vs. Ontological Priority

The Latin ante naturally suggests temporal precedence. A literal translation—“before the thing”—may encourage readers to think of universals as earlier in time than particulars. However:

  • Most philosophical uses intend logical or ontological priority, not temporal sequence.
  • Many scholastics and contemporary realists regard universals as timeless or eternal.

Translators therefore face a choice among renderings such as:

  • “Prior to things” (ambiguous).
  • “Independent of things” (may downplay priority).
  • Retaining the Latin ante rem (preserves technical flavor but requires explanation).

Breadth of rēs

The term rēs can mean “thing,” “matter,” “fact,” or “affair.” Limiting it to concrete objects may:

  • Obscure uses where states of affairs or facts are in view.
  • Narrow the perceived scope of debates about universals to physical particulars alone.

This complicates the interpretation of ante rem as relating strictly to individual objects; in some contexts, it may also concern the priority of ideal structures to complex states of affairs.

Risk of Over-Platonizing

Another pitfall is the tendency to treat all uses of ante rem as straightforwardly “Platonic”:

  • Some medieval authors employ ante rem language only within the context of divine ideas, not to posit a realm of autonomous Forms.
  • Contemporary uses of “ante rem realism” may differ significantly from historical Platonism, focusing on properties or sets rather than on Plato’s Forms.

Over-assimilating diverse positions to a single “Platonic” model can obscure important distinctions between, for example, Aquinas’s exemplarism and Scotus’s common nature doctrine.

Anachronism and Taxonomy

Modern taxonomies (ante rem vs. in re vs. nominalism) are sometimes projected backwards onto historical figures who did not use the triad explicitly or who operated with different conceptual priorities. This can lead to:

  • Over-schematic readings that force authors into neat categories they themselves would not recognize.
  • Misinterpretation of nuanced positions that straddle or revise the standard distinctions.

Careful interpretation requires attending both to the original Latin context and to the philosophical problems an author is addressing, avoiding the assumption that every use of “before the thing” straightforwardly endorses robust ante rem universals.

Polysemy in Modern Usage

In contemporary English-language philosophy, “ante rem” can:

  • Serve as a technical label in metaphysics (universals independent of instances).
  • Function within philosophy of mathematics to characterize structuralist or Platonist positions.

Without clarification, this polysemy can generate misunderstandings, especially when crossing sub-disciplinary boundaries.

15. Legacy and Historical Significance

The notion of ante rem has exerted lasting influence on how philosophers conceptualize universals, abstract objects, and modes of being.

Structuring the Problem of Universals

Historically, the triad ante rem / in re / post rem became a standard framework for:

  • Classifying positions in the medieval problem of universals.
  • Organizing subsequent debates in early modern and contemporary metaphysics.

This classificatory role persists in current textbooks and scholarly discussions, where “ante rem realism” functions as a convenient shorthand for a family of strong realist views.

Integration with Theological and Metaphysical Systems

In medieval thought, ante rem language enabled philosophers to articulate:

  • The doctrine of divine ideas and exemplarism.
  • The relationship between God’s intellect and the structure of created reality.

This provided a way to integrate metaphysical realism about universals with Christian theology, leaving a durable imprint on later theological and philosophical traditions.

Influence on Analytic Metaphysics and Philosophy of Mathematics

In the 20th and 21st centuries, the ante rem idea has been reinterpreted within:

  • Theories of universals and properties in analytic metaphysics.
  • Platonist and structuralist accounts in the philosophy of mathematics.

The term informs ongoing discussions about:

  • The existence and nature of abstract entities.
  • The explanatory role of universals and structures in science and mathematics.
  • The epistemology of non-empirical knowledge.

Continuing Debates

The endurance of ante rem as a conceptual tool is linked to enduring questions:

  • Are universals or structures independent realities or merely conceptual/linguistic constructs?
  • How should we understand the priority and dependence relations between abstract entities and concrete particulars?
  • What ontological commitments are required to account for the success of science and mathematics?

While specific formulations have evolved, the ante rem idea continues to shape discussions about realism, abstraction, and the architecture of reality, serving as a bridge between medieval scholasticism and contemporary analytic philosophy.

Key Concepts

Ante rem

A mode of existence for universals or abstract entities according to which they exist prior to and independently of the particular things that instantiate them, often in a separate realm or in the divine intellect.

In re

The mode of being of universals as they exist only in and through particular things as their forms, essences, or properties (immanent realism).

Post rem

The mode of being of universals as concepts abstracted by the intellect from particular things; universals exist only in the mind after experience of individuals.

Universalia (universals)

General items—kinds, properties, relations—that can be predicated of many individuals (e.g., humanity, redness), whose ontological status is at issue in debates about ante rem realism.

Natura communis (common nature)

In Scotus, a nature that is in itself neither universal nor singular but can be multiplied in individuals and considered as a universal; it underlies both ante rem and in re aspects.

Idea divina (divine idea) and exemplarism

Divine ideas are concepts in God’s intellect that serve as exemplars for created things; exemplarism is the doctrine that creatures are patterned on such exemplars, often understood as universals ante rem.

Realismus ante rem vs. realismus in re vs. nominalismus

Realismus ante rem affirms universals independent of instances; realismus in re holds that universals exist only in particulars; nominalismus denies extra-mental universals altogether, treating them as names or mental devices.

Priority and dependence (logical and ontological)

Logical priority concerns order of explanation or implication; ontological priority concerns what is more fundamental or independent in being. Ante rem universals are often said to be ontologically and logically prior to their instances.

Discussion Questions
Q1

In what precise sense is ‘priority’ involved when we say that universals exist ante rem, and how does this differ from mere temporal priority?

Q2

Compare the ways Aquinas and Duns Scotus each incorporate an ante rem dimension into their accounts of universals. To what extent is Scotus’s natura communis more ‘robustly’ ante rem than Aquinas’s divine ideas?

Q3

How does the scholastic triad (ante rem, in re, post rem) help to classify nominalism and conceptualism, and what limitations does this triad have for accurately capturing their views?

Q4

Do contemporary ante rem realists about mathematical structures face the same epistemic challenges as medieval realists about universals? Why or why not?

Q5

Is it possible to be a realist about universals while rejecting any ante rem mode of existence? What might such a position look like, and what are its costs and benefits?

Q6

How do translation choices for ‘ante rem’ (e.g., ‘before the thing’ vs. ‘independently of things’) affect the way students initially understand medieval debates on universals?

Q7

In what ways does exemplarism rely on an ante rem conception of universals, and how could a nominalist reinterpret exemplarist language without accepting real universals in the divine intellect?
