A prior paper established constraint as an ontological primitive: the transcendental condition of determinacy, distinction, and existence as such (Prideaux, 2026c). A companion paper demonstrated that moral order is structurally homologous to constraint propagation at the social level (Prideaux, 2026a). Subsequent work extended Constraint Theory (CT) across the philosophy of physics, mathematics, mind, language, aesthetics, biology, causation, personal identity, free will, psychopathology, political philosophy, and artificial intelligence alignment (Prideaux, 2026e). The present paper extends CT into a further set of (...) practical and policy domains, arguing that the same structural principle — the distinction between constitutive and merely restrictive constraint — generates analytically precise and prescriptively non-trivial results in education, fiscal policy, democratic theory, organisational design, urban planning, climate policy, and the theory of computation. -/- The paper’s central argument is that the standard approach to constraint in policy and practice treats it as merely restrictive: the prohibition of certain behaviours within a pre-given possibility space. This approach generates a characteristic failure mode across all domains — the Goodhart pathology, regulatory evasion, institutional erosion, pedagogical stagnation, and computational intractability are all expressions of the same structural error. The CT framework identifies the structural alternative: constitutive constraint, which generates the possibility space rather than limiting it. In every domain examined, the CT prescription is structurally identical: ask not what should be prohibited but what constraint structure should be constituted, recognising that constitutive constraints are more robust, more durable, and more generative than any collection of merely restrictive rules. -/- The paper presents each application as a structured sketch sufficient to demonstrate CT’s analytical power and prescriptive reach in that domain, rather than as a full treatment of the domain’s internal debates.

The aim of this paper is to summarize a particular approach of doing metaphysics through physics - the primitive ontology approach. The idea is that any fundamental physical theory has a well-defined architecture, to the foundation of which there is the primitive ontology, which represents matter. According to the framework provided by this approach when applied to quantum mechanics, the wave function is not suitable to represent matter. Rather, the wave function has a nomological character, given that its (...) role in the theory is to implement the law of evolution for the primitive ontology. (shrink)

Primitive ontology is a recently much discussed approach to the ontology of quantum theory according to which the theory is ultimately about entities in 3-dimensional space and their temporal evolution. This paper critically discusses the primitive ontologies that have been suggested within the Bohmian approach to quantum field theory in the light of the existence of unitarily inequivalent representations. These primitive ontologies rely either on a Fock space representation or a wave functional representation, which are strictly speaking (...) unambiguously available only for free systems in flat spacetime. As a consequence, it is argued that they do not constitute fundamental ontologies for quantum field theory, in contrast to the case of the Bohmian approach to quantum mechanics. (shrink)

A prior paper established constraint as an ontological primitive: the transcendental condition of determinacy, distinction, and existence as such (Prideaux, 2026a). A companion paper demonstrated that moral order is structurally homologous to thermodynamic constraint dynamics (Prideaux, 2026c), and a third paper offered a structuralist resolution of the problem of evil grounded in the ontological necessity of limitation for manifestation (Prideaux, 2026b). The present paper extends the research programme by identifying seven further philosophical domains in which Constraint Theory supplies either (...) novel explanatory traction or previously unavailable formal precision: the philosophy of mathematics, the philosophy of mind and personal identity, political philosophy, aesthetics, philosophy of language, metaphysics of causation and time, and psychopathology. For each domain, the paper articulates the core application, identifies the specific gap or puzzle that constraint-theoretic analysis addresses, traces the relevant existing literature, and proposes a proof-of-principle argument demonstrating the framework’s fertility. The paper does not exhaust any domain but establishes that the constraint-theoretic approach constitutes a genuine research programme with implications across the central areas of philosophy. It is offered as an invitation to further development by the philosophical community. (shrink)

One reason to posit governing laws is to explain the uniformity of nature. Explanatory power can be purchased by accepting new primitives, and scientists invoke laws in their explanations without providing any supporting metaphysics. For these reasons, one might suspect that we can treat laws as wholly unanalyzable primitives. (John Carroll’s *Laws of Nature* (1994) and Tim Maudlin’s *The Metaphysics Within Physics* (2007) offer recent defenses of primitivism about laws.) Whatever defects primitive laws might have, explanatory weakness should not (...) be one of them. However, in this essay I’ll argue that wholly primitive laws cannot explain the uniformity of nature. The basic argument is based on the following idea: though a primitive law that P makes P likely, the primitive status of the law provides no reason to think that P must describe (or otherwise give rise to) a natural regularity. After identifying the problem for primitive laws, I consider an extension of the objection to all theories of governing laws and suggest that it may be avoided by a version of the Dretske/Tooley/Armstrong theory according to which laws are relations between universals.

In this paper I present the common structure of quantum theories with a primitive ontology, and discuss in what sense the classical world emerges from quantum theories as understood in this framework. In addition, I argue that the primitive ontology approach is better at answering this question than the rival wave function ontology approach or any other approach in which the classical world is nonreductively ‘emergent:’ even if the classical limit within this framework needs to be fully developed, (...) the difficulties are technical rather than conceptual, while this is not true for the alternatives.

The article sets out a primitive ontology of the natural world in terms of primitive stuff—that is, stuff that has as such no physical properties at all—but that is not a bare substratum either, being individuated by metrical relations. We focus on quantum physics and employ identity-based Bohmian mechanics to illustrate this view, but point out that it applies all over physics. Properties then enter into the picture exclusively through the role that they play for the dynamics of (...) the primitive stuff. We show that such properties can be local, as well as holistic, and discuss two metaphysical options to conceive them, namely, Humeanism and modal realism in the guise of dispositionalism. 1 Introduction2 Primitive Ontology: Primitive Stuff3 The Physics of Matter as Primitive Stuff4 The Humean Best System Analysis of the Dynamical Variables5 Modal Realism about the Dynamical Variables6 Conclusion.

The paper explains in what sense the GRW matter density theory is a primitive ontology theory of quantum mechanics and why, thus conceived, the standard objections against the GRW formalism do not apply to GRWm. We consider the different options for conceiving the quantum state in GRWm and argue that dispositionalism is the most attractive one.

Metaphysical theories heavily rely on the use of primitives to which they typically appeal. I will start by examining and evaluating some traditional well-known theories and I will discuss the role of primitives in metaphysical theories in general. I will then turn to a discussion of claims of between theories that, I think, depend on equivalences of primitives, and I will explore the nature of primitives. I will then claim that almost all explanatory power of metaphysical theories comes from their (...) primitives, and so I will turn to scrutinize the notion of "power" and "explanatory". (shrink)

This essay argues that contemporary climate migration must be understood not simply as a response to environmental disaster, but as a central mechanism of planetary primitive accumulation under global capitalism. As climate change displaces migrants, global capitalism exploits this mobility through mass dispossession, racialized border regimes, and labor devalorization. Capitalist produced climate change generates profits through border industries and the hyper-exploitation of migrant labor. To respond, we must abandon static models of states and citizenship and embrace a politics of (...) movement in the Anthropocene—what I call the Kinocene—rooted in anti-capitalist, decolonial, and cosmopolitan ethics.

Eternalists believe that there is no ontological difference between the past, present and future. Thus, a challenge arises: in virtue of what does time have a direction? Some eternalists, Oaklander and Tegtmeier ) argue that the direction of time is primitive. A natural response to positing primitive directionality is the suspicion that said posit is too mysterious to do any explanatory work. The aim of this paper is to relieve primitive directionality of some of its mystery by (...) offering a novel way to understand the phenomenon in terms of the recently popularised notion of grounding.

For a long time it was believed that it was impossible to be realist about quantum mechanics. It took quite a while for the researchers in the foundations of physics, beginning with John Stuart Bell [Bell 1987], to convince others that such an alleged impossibility had no foundation. Nowadays there are several quantum theories that can be interpreted realistically, among which Bohmian mechanics, the GRW theory, and the many-worlds theory. The debate, though, is far from being over: in what respect (...) should we be realist regarding these theories? Two diff erent proposals have been made: on the one hand, there are those who insist on a direct ontological interpretation of the wave function as representing physical bodies, and on the other hand there are those who claim that quantum mechanics is not really about the wave function. In this paper we will present and discuss one proposal of the latter kind that focuses on the notion of primitive ontology. (shrink)

Primitive ontology is a program which seeks to make explicit the ontological commitments of physical theories in terms of a distribution of matter in ordinary space-time. This program targets wave-function realism, which interprets the high-dimensional configuration space on which wave-functions are defined as our fundamental physical space. Wave-function realism allegedly fails to account for a correspondence between the ontology it postulates and the ‘manifest image’ of the world in which experimental tests of the theory are performed, and therefore the (...) wave-function must be completed with an additional structure which describes what fundamentally exists in ordinary space-time: the ‘primitive ontology’. However primitive ontologies face some difficulties, in particular concerning the ontological status of the wave-function. In this paper, I defend a realist interpretation of the wave-function as describing objects in ordinary space-time, which does not require supplementing the theory with additional structure. The main difference between this proposal and other primitive ontology proposals is that the fundamental constituents of reality are not conceived of as localised objects, but as primitive relations. This interpretation purports to share the advantages of both wave-function realism and primitive ontologies without facing the same difficulties. I argue that the need for an additional structure stems from a commitment to the locality of the fundamental constituents of reality, and that such commitment is unnecessary for recovering the manifest image of the world.

This paper examines Hannah Ginsborg's attempt to address the challenge raised by Saul Kripke's meaning sceptic. I start by identifying the two constraints that the sceptic claims must be met by a satisfactory answer. Then I try to show that Ginsborg's proposal faces a dilemma. In the first instance, I argue that it is able to meet the second constraint, but not the first. I then amend the proposal in order to make room for the first constraint. I go on (...) to argue that, under this new interpretation, it cannot meet the second constraint. (shrink)

Joshua Gert presents an original account of color properties, and of our perception of them. He employs a general philosophical strategy - neo-pragmatism - which challenges an assumption made by virtually all other theories of color: he argues that colors are primitive properties of objects, irreducible to physical or dispositional properties.

A major disagreement between different views about the foundations of quantum mechanics concerns whether for a theory to be intelligible as a fundamental physical theory it must involve a ‘primitive ontology’ (PO), i.e. variables describing the distribution of matter in four-dimensional space–time. In this article, we illustrate the value of having a PO. We do so by focusing on the role that the PO plays for extracting predictions from a given theory and discuss valid and invalid derivations of predictions. (...) To this end, we investigate a number of examples based on toy models built from the elements of familiar interpretations of quantum theory. (shrink)

ABSTRACT There is an important debate in the philosophy of mind that has roots in the phenomenological tradition, namely: what are the primitive forms of consciousness, that is, what are the fundamental ingredients or aspects of consciousness. This paper wants to contribute to partially answering this general question by providing an answer to a required sub-question within this question: is emotional phenomenology fundamental? I will answer in the affirmative and will offer an argument focused on contemplative emotions elicited by (...) fiction. Another type of contemplative emotions, namely, esthetic emotions, have been invoked in the literature but I will argue that the phenomenology of emotions elicited by fiction, given their continuity and sameness in kind with the phenomenology of garden variety emotions, are more dialectically efficient vis-à-vis the debate on the irreducibility of emotional phenomenology.

The paper seeks to make progress from stating primitive ontology theories of quantum physics – notably Bohmian mechanics, the GRW matter density theory and the GRW flash theory – to assessing these theories. Four criteria are set out: internal coherence; empirical adequacy; relationship to other theories; explanatory value. The paper argues that the stock objections against these theories do not withstand scrutiny. Its focus then is on their explanatory value: they pursue different strategies to ground the textbook formalism of (...) quantum mechanics, and they develop different explanations of quantum non-locality. In conclusion, it is argued that Bohmian mechanics offers a better prospect for making quantum non-locality intelligible than the GRW matter density theory and the GRW flash theory. (shrink)

In my dissertation I analyze the structure of fundamental physical theories. I start with an analysis of what an adequate primitive ontology is, discussing the measurement problem in quantum mechanics and theirs solutions. It is commonly said that these theories have little in common. I argue instead that the moral of the measurement problem is that the wave function cannot represent physical objects and a common structure between these solutions can be recognized: each of them is about a clear (...) three-dimensional primitive ontology that evolves according to a law determined by the wave function. The primitive ontology is what matter is made of while the wave function tells the matter how to move. One might think that what is important in the notion of primitive ontology is their three-dimensionality. If so, in a theory like classical electrodynamics electromagnetic fields would be part of the primitive ontology. I argue that, reflecting on what the purpose of a fundamental physical theory is, namely to explain the behavior of objects in three--dimensional space, one can recognize that a fundamental physical theory has a particular architecture. If so, electromagnetic fields play a different role in the theory than the particles and therefore should be considered, like the wave function, as part of the law. Therefore, we can characterize the general structure of a fundamental physical theory as a mathematical structure grounded on a primitive ontology. I explore this idea to better understand theories like classical mechanics and relativity, emphasizing that primitive ontology is crucial in the process of building new theories, being fundamental in identifying the symmetries. Finally, I analyze what it means to explain the word around us in terms of the notion of primitive ontology in the case of regularities of statistical character. Here is where the notion of typicality comes into play: we have explained a phenomenon if the typical histories of the primitive ontology give rise to the statistical regularities we observe.

Primitives are both important and unavoidable, and which set of primitives we endorse will greatly shape our theories and how those theories provide solutions to the problems that we take to be important. After introducing the notion of a primitive posit, I discuss the different kinds of primitives that we might posit. Following Cowling (2013), I distinguish between ontological and ideological primitives, and, following Benovsky (2013) between functional and content views of primitives. I then propose that these two distinctions (...) cut across each other leading to four types of primitive posits. I then argue that theoretical virtues should be taken to be meta-theoretical ideological primitives. I close with some reflections on the global nature of comparing sets of primitives. (shrink)

The relation between primitive and derivative forces may be the hardest problem about the relation between Leibniz's physics and his metaphysics. He holds that derivative forces are modifications of primitive forces, but also that physical forces, which he classifies as derivative forces, belong to bodies, which are aggregates, whereas primitive forces belong to unextended perceiving substances (monads) and constitute their essence. This chapter addresses this problem, arguing that a major part of it can be solved on the (...) supposition that physical events are only phenomena, and hence ultimately determined by modifications of the primitive forces of perceiving substances (monads).

Intuitively, it seems that some belief-forming practices have the following three properties: 1. They are rational practices, and the beliefs that we form by means of these practices are themselves rational or justified beliefs. 2. Even if in most cases these practices reliably lead to correct beliefs (i.e., beliefs in true propositions), they are not infallible: it is possible for beliefs that are formed by means of these practices to be incorrect (i.e., to be beliefs in false propositions). 3. The (...) rationality of these practices is basic or primitive. That is, the rationality of these practices is not due simply to the availability, by means of some process of reasoning that relies purely on other practices, of a rational or justified belief in the reliability of these practices. -/- How can there be such practices?

Recent work in moral theory has seen the refinement of theories of moral standing, which increasingly recognize a position of intermediate standing between fully self-conscious entities and those which are merely conscious. Among the most sophisticated concepts now used to denote such intermediate standing is that of primitive self-consciousness, which has been used to more precisely elucidate the moral standing of human newborns. New research into the structure of the avian brain offers a revised view of the cognitive abilities (...) of birds. When this research is approached with a species-specific focus, it appears likely that one familiar species, the chicken (Gallus gallus domesticus), also exhibits primitive self-consciousness. Given the likelihood that they are primitively self-consciousness, chickens warrant a degree of moral standing that falls short of that enjoyed by persons, but which exceeds the minimal standing of merely conscious entities.

Theories of collective intentions must distinguish genuinely collective intentions from coincidentally harmonized ones. Two apparently equally apt ways of doing so are the ‘neo-reductionism’ of Bacharach (2006) and Gold and Sugden (2007a) and the ‘non-reductionism’ of Searle (1990, 1995). Here, we present findings from theoretical linguistics that show that we is not a cognitive primitive, but is composed of notions of I and grouphood. The ramifications of this finding on the structure both of grammatical and lexical systems suggests that (...) an understanding of collective intentionality does not require a primitive we-intention, but the notion of grouphood implicit in team reasoning, coupled with the individual concept I. This, we argue, supports neo-reductionism but poses difficulties for non-reductionism. (shrink)

We propose a structuralist reconstruction of the real continuum, arguing that it is not a primitive ontological stage for physics but an emergent completion of the prime-exponent lattice M. By identifying the reals R as the Dedekind completion of M, we demonstrate that the natural logarithm and exponential functions are not merely analytic tools but inevitable algebraic consequences of identifying the multiplicative structure of number theory with the additive structure of the continuum. Furthermore, we show that the natural base (...) e is the unique structural invariant required to normalize the gauge freedom inherent in this identification. Finally, we refine the Erdős–Kac theorem to argue that the "Triple-Log" scale (ln ln ln n) emerges as a deterministic background limit of arithmetic, providing an intrinsic argument for a natural ultraviolet cutoff in physical theories without external imposition. In the language of Ontic Structural Realism (OSR), this framework suggests that the 'physical continuum' is not an object-like substance, but a structural instantiation of the relation between the additive and multiplicative sectors of arithmetic.

In this article, we study some new characterizations of primitive recursive functions based on restricted forms of primitive recursion, improving the pioneering work of R. M. Robinson and M. D.

We reduce certain recursion schemes (mixed/pure iteration without parameters) and we characterize one-argument primitive recursive functions as the closure under substitution and iteration of certain optimal sets.

Quantum mechanics has always been regarded as, at best, puzzling, if not contradictory. The aim of the paper is to explore a particular approach to fundamental physical theories, the one based on the notion of primitive ontology.

If $\mathcal{A}$ (V) is a net of local von Neumann algebras satisfying standard axioms of algebraic relativistic quantum field theory and V 1 and V 2 are spacelike separated spacetime regions, then the system ( $\mathcal{A}$ (V 1 ), $\mathcal{A}$ (V 2 ), φ) is said to satisfy the Weak Reichenbach's Common Cause Principle iff for every pair of projections A∈ $\mathcal{A}$ (V 1 ), B∈ $\mathcal{A}$ (V 2 ) correlated in the normal state φ there exists a projection C (...) belonging to a von Neumann algebra associated with a spacetime region V contained in the union of the backward light cones of V 1 and V 2 and disjoint from both V 1 and V 2 , a projection having the properties of a Reichenbachian common cause of the correlation between A and B.

When discussing quantum ontology, the debate has recently focused on comparing and contrasting wavefunction realism and its rivals.

I argue that the primitive ontology is the local beable which allows for a dynamical, constructive explanation (...) which preserves symmetries. (shrink)

This essay emphasizes how Vico was one of the modern philosophers to set himself the goal to reconstruct the history of the primitive world. Differently from several authors who preceded him and also other contemporary thinkers, the Neapolitan philosopher showed that the world of the origin wasn’t idyllic, but it was affected by fear, anguish and basic needs. What mainly characterizes Vico, however, is the fact that he represented the primitive world not as a unitary and fixed block, (...) but as a world made of different historical phases and of class and social conflicts. As there were no written documents, Vico elaborated a reconstruction of history, basing it on a new and revolutionary theory of myths which, being based on creativity induced by fantasy, are called “universali fantastici”.

During the last few decades, the concept of primitive accumulation (ursprüngliche Akkumulation) introduced by Karl Marx and expanded by Rosa Luxemburg has been revived and improved. Accordingly, scholars have used this framework not to characterize a past moment in the history of capitalism, but to grasp the continuous process of coupling and uncoupling geographical and social spheres in the capital accumulation in different fields: financialization, the care economy, green grabbing, the sharing economy, real estate bubbles, data mining, etc. Despite (...) the quality and productivity of these debates, they are still focused on authors and phenomena observed in the Global North, ignoring a long tradition of similar discussions developed especially in Latin America. The article seeks to decentre these debates by taking seriously into account approaches which address primitive accumulation from the perspective of (post)colonial and (post)slave societies. It coins the concept entangled accumulation to emphasize the interdependencies between practices of exploitation and expropriation, wage and slave labour, state power and illegal violence, and capitalist and non-capitalist economies, which have shaped capital accumulation throughout history.

In mathematics, various representations of real numbers have been investigated. All these representations are mathematically equivalent because they lead to the same real structure – Dedekind-complete ordered field. Even the effective versions of these representations are equivalent in the sense that they define the same notion of computable real numbers. Although the computable real numbers can be defined in various equivalent ways, if “computable” is replaced by “primitive recursive”, these definitions lead to a number of different concepts, which we (...) compare in this article. We summarize the known results and add new ones. In particular we show that there is a proper hierarchy among p. r. real numbers by nested interval representation, Cauchy representation, b -adic expansion representation, Dedekind cut representation, and continued fraction expansion representation. Our goal is to clarify systematically how the primitive recursiveness depends on the representations of the real numbers. (shrink)

Drawing upon a distinction between epistemically and metaphysically motivated notions of a concept, I consider the insurmountable problems of theories that appeal to our epistemic capacities to address the problem of the nature of concepts satisfactorily. Prominent theories of concepts hold that primitive concepts must have internal structure if they are to account for the explanatory functions that cognitive scientists have attributed to such constructs as prototypes, exemplars, and theories. Vindicating the role of non-experimental philosophy in the critical examination (...) of empirical theories, I argue that the explanatory effectiveness of those constructs is orthogonal to an argument concerning the structure of primitive concepts. Conceptual atomism provides an alternative approach to individuating primitive concepts the precise formulation of which has yet to be worked out. Despite its unpopularity, the atomist alternative is still in a better position to face the question of what concepts are than its competitors. (shrink)

Social entities only exist in virtue of collective acceptance or recognition, or acknowledgement by two or more individuals in the context of joint activities. Joint activities are made possible by the coordination of plans for action, and the coordination of plans for action is made possible by the capacity for collective intentionality. This paper investigates how primitive is the capacity that nonhuman animals have to create social entities, by individuating how primitive is the capacity for collective intentionality. I (...) present a novel argument for the evolutionary primitiveness of social entities, by showing that the collective intentions upon which these social entities are created and shared are metaphysically reducible to the relevant individual intentions.

A notion of strictly primitive recursive realizability is introduced by Damnjanovic in 1994. It is a kind of constructive semantics of the arithmetical sentences using primitive recursive functions. It is of interest to study the corresponding predicate logic. It was argued by Park in 2003 that the predicate logic of strictly primitive recursive realizability is not arithmetical. Park’s argument is essentially based on a claim of Damnjanovic that intuitionistic logic is sound with respect to strictly primitive (...) recursive realizability, but that claim was disproved by the author of this article in 2006. The aim of this paper is to present a correct proof of the result of Park. (shrink)

It has recently been alleged that expressivism cannot account for the obvious fact that normative sentences and their negations express inconsistent kinds of attitudes. I explain how the expressivist can respond to this objection. I offer an account of attitudinal inconsistency that takes it to be a combination of descriptive and normative relations. The account I offer to explain these relations relies on a combination of functionalism about normative judgments and expressivism about the norms governing them. It holds that the (...) inconsistency of normative judgments is primitive. One potential problem for this view is that the large number of normative primitives that the expressivist will allegedly need to accept will render the view grossly unparsimonious. In defending this thesis, I suggest that it is a mistake to hold the lack of normative parsimony of expressivism against its core psychological claims. (shrink)

The paper has two aims: (1) it sets out to show that it is well motivated to seek for an account of quantum non-locality in the framework of ontic structural realism (OSR), which integrates the notions of holism and non-separability that have been employed since the 1980s to achieve such an account. However, recent research shows that OSR on its own cannot provide such an account. Against this background, the paper argues that by applying OSR to the primitive ontology (...) theories of quantum physics, one can accomplish that task. In particular, Bohmian mechanics offers the best prospect for doing so. (2) In general, the paper seeks to bring OSR and the primitive ontology theories of quantum physics together: on the one hand, in order to be applicable to quantum mechanics, OSR has to consider what the quantum ontology of matter distributed in space-time is. On the other hand, as regards the primitive ontology theories, OSR provides the conceptual tools for these theories to answer the question of what the ontological status of the wave-function is.

This article surveys recent work on primitive ontology (PO) approaches to quantum mechanics, focusing on proposals that seek to integrate this approach with the metaphysics of causal powers. PO approaches aim to provide a clear metaphysical picture in which the world consists of local entities such as particles, matter density fields or flashes, and these entities compose macroscopic objects, such as scientists and their measuring devices. To account for the behaviour of these local entities, some PO theories invoke the (...) metaphysics of powers. After motivating PO approaches and contrasting them with wave function realism, I consider the development of power‐based POs, contrasting them with both Humean POs and POs which invoke primitive laws. I explain how different power‐based frameworks address key quantum phenomena, and I survey some difficulties, including the Problem of Holism, of small worlds and of top‐down causation. Such challenges are best confronted, I suggest, by drawing on Aristotelian hylomorphism: If powers are grounded in forms that unify physical systems, then power‐based POs can accommodate holistic and context‐sensitive behaviour.

I argue that McDowell-style disjunctivism, as the position is often cashed out, goes wrong because it takes the good epistemic standing of veridical perception to be grounded in “manifest” facts which do not necessarily satisfy any epistemic constraints. A better form of disjunctivism explains the difference between good and bad cases in terms of epistemic constraints that the states satisfy. This view allows us to preserve McDowell’s thesis that good cases make facts manifest, as long as manifest facts must satisfy (...) epistemic constraints. (shrink)

There is no doubt that spatial relations aid us in pairing up causes and effects. But when we consider the possibility of qualitatively indiscernible things, it might seem that spatial relations are more than a mere aid – they might seem positively required. The belief that spatial relations are required for causal relations is behind an important objection to Cartesian Dualism, the pairing problem. I argue that the Cartesian can answer this objection by appeal to the possibility of primitive (...) causal relations, a possibility I defend. This topic is of importance beyond the philosophy of mind; the possibility that causal relations might sometimes hold brutely is of general metaphysical importance. I close with a discussion of what Cartesians should say about embodiment, and how that bears on issues of mental causation. (shrink)

The primitive streak establishes the antero‐posterior body axis in all amniote species. It is thought to be the conduit through which mesoderm and endoderm progenitors ingress and migrate to their ultimate destinations. Despite its importance, the streak remains poorly defined and one of the most enigmatic structures of the animal kingdom. In particular, the posterior end of the primitive streak has not been satisfactorily identified in any species. Unexpectedly, and contrary to prevailing notions, recent evidence suggests that the (...) murine posterior primitive streak extends beyond the embryo proper. In its extraembryonic site, the streak creates a node‐like cell reservoir from which the allantois, a universal caudal appendage of all amniotes and the future umbilical cord of placental mammals, emerges. This new insight into the fetal/umbilical relationship may explain the etiology of a large number of umbilical‐associated birth defects, many of which are correlated with abnormalities of the embryonic midline.

Rational agents seem more confident in any possible event than in an impossible event. But if rational credences are real-valued, then there are some possible events that are assigned 0 credence nonetheless. How do we differentiate these events from impossible events then when we order events? de Finetti (1975), Hájek (2012) and Easwaran (2014) suggest that when ordering events, conditional credences and subset relations are as relevant as unconditional credences. I present a counterexample to all their proposals in this paper. (...) While their proposals order possible and impossible events correctly, they deliver the wrong verdict for disjoint possible events assigned equal positive credence. (shrink)

This paper is a companion to work of Feferman, Jäger, Glaß, and Strahm on the proof theory of the type two functionals μ and E1 in the context of Feferman-style applicative theories.

The proof-theoretic strength of PRON augmented by μ and E1 is measured in terms of the two subsystems (...) of second order arithmetic, Π10-CA and Π11-CA, respectively. (shrink)
