Latitudinarianism is a philosophical position that occupies a precise niche in the long‑standing debate over de dicto and de re attitudes. While the terminology may sound obscure, the issue it addresses lies at the heart of how we think about belief, reference, and the logical form of our mental states. This article offers a comprehensive, in‑depth exploration of latitudinarianism, tracing its origins, unpacking its core claim, examining why it matters for broader philosophical inquiry, and illustrating the view with concrete examples. The discussion is framed for the Apiary community, whose mission of fostering thoughtful, self‑governing AI agents benefits from clarity about how agents can represent and export propositional content.
The De Dicto / De Re Distinction: A Primer
Before delving into latitudinarianism itself, it helps to understand the broader landscape of de dicto and de re attitudes. These terms originate in the philosophy of language and epistemology and refer to two different ways of relating mental states (like belief, desire, or knowledge) to the world.
| Aspect | De Dicto Attitude | De Re Attitude |
|---|---|---|
| Logical Form | The attitude is directed at a proposition (a sentence‑like content). | The attitude is directed at an object or individual with a property. |
| Typical Example | “Alice believes that the tallest building in the city is over 200 m.” | “Alice believes the tallest building in the city is over 200 m.” |
| Scope of Reference | The proposition may contain quantifiers or descriptions that are intensional (sensitive to the way the world is described). | The reference is extensional: the object is picked out independently of the description. |
| Philosophical Significance | Central to discussions of propositional attitude ascription, substitution failures, and intensional contexts. | Central to debates about direct reference, essential properties, and the possibility of de re knowledge. |
The distinction is not merely linguistic; it influences how we model agents that hold beliefs, how we evaluate the truth‑conditions of those beliefs, and whether we can export propositional content from one context to another without loss of meaning.
Introducing Latitudinarianism
Latitudinarianism is a specific answer to the question: Are de re attitudes a distinct logical category, or can they be reduced to de dicto attitudes?
The latitudinarian position holds that de re attitudes are not a separate category. Instead, they are a special case of de dicto attitudes. In other words, whenever we think we are dealing with a de re attitude, we are actually dealing with a de dicto attitude that happens to have a particular form. The view thus collapses the apparent bifurcation between the two kinds of attitudes into a single, more general framework.
Key points of the latitudinarian claim:
- No Ontological Dualism – There is no need to posit a second kind of mental state distinct from propositional attitudes.
- Uniform Exportation – The logical operations that apply to de dicto attitudes can be unrestrictedly applied to de re cases as well.
- Conceptual Economy – By treating de re attitudes as a subset of de dicto attitudes, the theory reduces the theoretical machinery required for a complete account of propositional attitude ascription.
The term “latitudinarianism” is deliberately evocative: it suggests a “broad” or “wide‑ranging” approach to the scope of de dicto attitudes, allowing them to stretch to cover what might otherwise be thought of as a separate class.
Historical Context: Chisholm’s 1976 Intervention
The label latitudinarianism entered philosophical discourse through Roderick Chisholm in his influential paper “Knowledge and Belief: ‘De Dicto’ and ‘De Re’” (1976). Chisholm’s work was part of a broader revival of analytic interest in the semantics of belief ascription, a topic that had been simmering since the early 20th century (e.g., Frege, Russell, and later Quine).
In that paper, Chisholm introduced the term to characterize a stance that rejects a sharp ontological split between de dicto and de re attitudes. By coining “latitudinarianism,” he provided a convenient shorthand for the “unrestricted exportation” view that would later be adopted by several philosophers concerned with the logical form of belief reports.
Since its introduction, the term has sometimes been called an “unrestricted exportation” view, underscoring the central methodological move of allowing propositional content to be exported across contexts without the need for a separate de re category.
The “Unrestricted Exportation” Reading
The phrase “unrestricted exportation” captures the technical heart of latitudinarianism. In the literature on propositional attitudes, exportation refers to the logical rule that permits moving a description from within the scope of an attitude operator (like believes) to the outside, or vice‑versa. For example, from:
(1) Alice believes that the tallest building in the city is over 200 m.
An unrestricted exportation rule would allow us to infer:
(2) The tallest building in the city is over 200 m, and Alice believes it.
Latitudinarians argue that such exportation is always legitimate, even when the description picks out a particular object. Consequently, the “de re” reading in (2) is not a new kind of attitude but merely a re‑phrasing of the original de dicto belief.
This view contrasts with more restrictive accounts that permit exportation only under certain epistemic or contextual conditions (e.g., when the description is transparent to the believer). Latitudinarianism’s unrestricted stance is what gives it its distinctive “broad” character.
Why the Debate Matters
Understanding whether de re attitudes are a distinct category has ripple effects across several philosophical sub‑fields:
- Philosophy of Language – The analysis of intensional contexts (e.g., belief reports, modal statements) hinges on whether we must treat de re and de dicto as separate logical forms. A unified account simplifies semantic theories.
- Epistemology – Questions about knowledge‑ascription (e.g., “knowing that” vs. “knowing who”) often mirror the de dicto/de re split. Latitudinarianism suggests that epistemic distinctions may be reducible to propositional distinctions.
- Metaphysics of Reference – If de re attitudes are just de dicto, then the metaphysical commitment to direct reference (objects being picked out without mediation) may be less robust than traditionally thought.
- Artificial Intelligence and Agent Modeling – For AI systems that must track beliefs about objects, a latitudinarian framework offers a single, uniform representation scheme, avoiding the need for a dual attitude architecture.
- Logic and Formal Semantics – The unrestricted exportation principle influences the design of formal languages that aim to capture natural‑language attitude ascriptions, affecting proof theory and model theory.
In each of these domains, the latitudinarian claim serves as a conceptual unifier, encouraging philosophers and AI designers to seek parsimonious explanations for complex mental-state phenomena.
Illustrative Scenarios
Below are several canonical scenarios that philosophers use to probe the de dicto/de re distinction. By applying latitudinarianism, we can see how the view interprets each case.
Scenario 1: The “Morning Star” vs. “Evening Star”
- Traditional Setup:
- De dicto: “John believes that the Morning Star is a planet.”
- De re: “John believes the Morning Star is a planet.”
- Latitudinarian Interpretation:
The belief that “the Morning Star is a planet” is a propositional attitude (de dicto). When we refer to the object “the Morning Star” directly, we are simply re‑expressing the same propositional content in a different linguistic guise. No new attitude type is introduced; the exportation from the description “the Morning Star” to the object is unrestricted.
Scenario 2: Misidentification
- Traditional Setup:
- Sarah sees a dog she calls “Fido.” Unbeknownst to her, the dog’s actual name is “Rex.”
- De dicto: “Sarah believes that Fido is friendly.”
- De re: “Sarah believes the dog she calls Fido is friendly.”
- Latitudinarian Interpretation:
The belief about “Fido” is still a propositional attitude. The phrase “the dog she calls Fido” is a description that can be exported without restriction, yielding a belief about the same object. The misidentification does not create a separate de re category; it merely reflects a different descriptive route to the same propositional content.
Scenario 3: Quantified Belief
- Traditional Setup:
- “Emily believes that some spy is trustworthy.”
- “Emily believes the spy is trustworthy.”
- Latitudinarian Interpretation:
The quantified belief is a de dicto attitude. When we substitute a particular spy (once identified) for the quantifier, we are still operating within the same propositional framework. The move from a quantified description to a specific object is an instance of unrestricted exportation.
These examples illustrate how latitudinarianism treats what appear to be distinct mental-state types as different linguistic presentations of a single underlying propositional attitude.
Philosophical Implications and Connections
1. Relation to Direct‑Reference Theories
Direct‑reference theories (e.g., those championed by Kripke and Putnam) argue that proper names and certain descriptions refer directly to objects, independent of descriptive content. Latitudinarianism, by collapsing de re into de dicto, softens the demand for a special “direct” mode of reference in the context of belief ascription. While it does not deny that names can refer directly, it suggests that the attitudinal relation does not require a separate logical category.
2. Interaction with Modal Logic
Modal operators (necessity, possibility) often interact with propositional attitudes in complex ways. If de re attitudes are just de dicto, then modalization of belief statements can be handled uniformly. For instance, the statement “It is possible that Alice believes the tallest building is over 200 m” reduces to a modalized de dicto belief, sidestepping any need for a distinct de re modal operator.
3. Cognitive Science and Mental Representation
Cognitive scientists studying how humans store and retrieve belief content frequently adopt symbolic representations. A latitudinarian stance supports a single representational format (propositional structures) for both “that‑statements” and object‑focused beliefs, potentially simplifying computational models of human cognition.
4. Formal Semantics and Logical Syntax
In formal semantics, the lambda‑calculus and type theory often differentiate between intensional and extensional types. Latitudinarianism encourages a type‑collapsing approach: de re attitudes can be treated as intensional types that happen to be instantiated by particular objects, eliminating the need for a separate extensional type for attitudes.
Potential Relevance to Apiary’s Mission
Apiary’s platform emphasizes self‑governing AI agents that must reason about their own and others’ beliefs. A clear, unified theory of belief representation is crucial for:
- Consistent belief updating: Agents can apply a single update rule to any belief, regardless of whether the belief is about a proposition or an object.
- Transparent communication: When agents exchange belief reports, unrestricted exportation ensures that the receiver can interpret statements without needing to infer a hidden de re structure.
- Ethical alignment: A parsimonious model of belief reduces the risk of unintended inference errors that could lead to misaligned actions.
While latitudinarianism is a philosophical thesis rather than an engineering specification, its emphasis on conceptual economy aligns with Apiary’s goal of building agents that are both robust and interpretable.
Criticisms and Counter‑Positions
Latitudinarianism is not without its detractors. Critics typically raise concerns along three lines:
- Empirical Plausibility
Some philosophers argue that ordinary speakers intuitively distinguish between “believing that” and “believing the object.” Experiments in experimental philosophy suggest that people treat de re attributions as more object‑focused than de dicto ones, challenging the unrestricted exportation claim.
