The first part of the paper is a metatheoretical consideration of such philosophy of nature which allows for using scientific results in philosophical analyses. An epistemological 'judgment' of those results becomes a preliminary task of this discipline: this involves taking a position in the controversy between realistic and antirealistic accounts of science. It is shown that a philosopher of nature has to be a realist, if his task to build true ontology of reality is to be achieved. At the (...) same time he cannot be a realist ˗ a possibility that science itself is capable of deciding what beings really exist (a typical realistic claim is that scientific notions refer to something external and truly describe its characteristics) has to be denied, if the philosophy of nature is seen as a discipline investigating the natural world, while being epistemologically different from the natural sciences. A possibility of weakening this opposition is explored in the second part of the paper, where the idea of so-called "postulated ontology" of scientific theories is brought to the consideration. This idea appears in the context of a well-known thesis of the underdetermination of scientific theories by empirical data. It is argued in the paper, that the conviction of the existence of some kind of relation between a given theory and ontological ideas can be derived from this thesis, regardless of its particular form. Therefore, certain solutions to classical philosophical questions can be obtained, in principle, by careful inspection of scientific achievements. However, if the thesis of underdetermination holds, such philosophical solutions are not imposed by science itself. In order to arrive at some kind of ontology based on science, it seems necessary to accept certain philosophical presuppositions in the first place. This and the fact that scientific theories change in time show that although such a kind of ontology is possible, and perhaps desirable, it can never be ultimate. (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.

The relationship between mathematical formalism, physical interpretation and epistemological appraisal in the practice of physical theorizing is considered in the context of Bohmian mechanics. After laying outthe formal mathematical postulates of thetheory and recovering the historical roots ofthe present debate over the meaning of Bohmianmechanics from the early debate over themeaning of Schrödinger's wave mechanics,several contemporary interpretations of Bohmianmechanics in the literature are discussed andcritiqued with respect to the aim of causalexplanation and an alternative interpretationis proposed. Throughout, the over-arching aimis (...) to exhibit the connections betweenmathematical, ontological and methodologicalquestions in physical theory and to reflect onthe rationality of physical theorizing in lightof the present case.

The philosophical study of what exists and what it means for something to exist is one of the core concerns of metaphysics. This introduction to ontology provides readers with a comprehensive account of the central ideas of the subject of being. This book is divided into two parts. The first part explores questions of pure philosophical ontology: what is meant by the concept of being, why there exists something rather than nothing, and why there is only one logically (...) contingent actual world. Dale Jacquette shows how logic provides the only possible answers to these fundamental problems. The second part of the book examines issues of applied scientific ontology. Jacquette offers a critical survey of some of the most influential traditional ontologies, such as the distinction between appearance and reality, and the categories of substance and transcendence. The ontology of physical entities - space, time, matter and causation - is examined as well as the ontology of abstract entities such as sets, numbers, properties, relations and propositions. The special problems posed by the subjectivity of mind and of postulating a god are also explored in detail. The final chapter examines the ontology of culture, language and art. (shrink)

In this article I address the issue of the ontological conditions of possibility for a naturalistic notion of emergence, trying to determine its fundamental differences from the atomist, vitalist, preformationist and potentialist alternatives. I will argue that a naturalistic notion of ontological emergence can only succeed if we explicitly refuse the atomistic fundamental ontological postulate that asserts that every entity is endowed with a set of absolutely intrinsic properties, being qualitatively immutable through its extrinsic relations. Furthermore, it will be shown (...) that, ironically enough, this metaphysical assumption is implicitly shared by all the above mentioned alternatives to Emergentism. The current article concludes that the notion of organization by itself is not enough, and that ontological emergence can only be justified by assuming a relational ontological perspective that, in opposition both to atomism and holism, defends that the existence-conditions, the identity and the causal behavior of any emergent systemic property can only be conceived, and explained, as constructed by and through specific networks of qualitatively transformative relational processes that occur between the system’s components and between the system and its environment. Additionally, I try to explain how one can make sense of the idea that an emergent phenomenon is both dependent on, and autonomous from, its emergence base. (shrink)

In the paper I analyze two features of the genre of the pedagogical. First is a particular usage of “should” statements where one can identify an effect of erasing present normative behavior, while that which is postulated is turned into an unattainable ideal, or a value. Second, I analyze “presumptive tautologies” in the discourse of aims of education. I focus on negative dimensions of these two features and, using theoretical insights from Laclau and Rancière, I connect them to the (...) work of negativity in political ontology so that the relation between the pedagogical and the political can thus be re-articulated.

A longstanding philosophical premise perceives simplicity as a desirable attribute of scientific theories. One of several raised justifications for this notion is that simple theories are more likely to indicate the true makeup of natural systems. Qualitatively parsimonious hypotheses and theories keep to a minimum the number of different postulated entities within a system. Formulation of such ontologically simple working hypotheses proved to be useful in the experimental probing of narrowly defined bio systems. It is less certain, however, whether (...) qualitatively parsimonious theories are effective indicators of the true nature of complex biological systems. This paper assesses the success of ontologically simple theories in envisaging the makeup of three complex systems in bacteriology, immunology, and molecular biology. Evidence shows that parsimonious theories completely misconstrued the actual ontologically complex constitutions of the three examined systems. Since evolution and selective pressures typically produce ontologically intricate rather than simple bio systems, qualitatively parsimonious theories are mostly inapt indicators of the true nature of complex biological systems.

Philosophical interpretations of theories generally presuppose that a theory can be presented as a consistent mathematical formulation that is interpreted through models. Algebraic quantum field theory (AQFT) can fit this interpretative model. However, standard Lagrangian quantum field theory (LQFT), as well as quantum electrodynamics and nuclear physics, resists recasting along such formal lines. The difference has a distinct bearing on ontological issues. AQFT does not treat particle interactions or the standard model. This paper develops a framework and methodology for interpreting (...) such informal theories as LQFT and the standard model. We begin by summarizing two minimal epistemological interpretation of non-relativistic quantum mechanics (NRQM): Bohrian semantics, which focuses on communicables; and quantum information theory, which focuses on the algebra of local observables. Schwinger's development of quantum field theory supplies a unique path from NRQM to QFT, where each step is conceptually anchored in local measurements. LQFT and the standard model rely on postulates that go beyond the limits set by AQFT and Schwinger's anabatic methodology. The particle ontology of the standard model is clarified by regarding the standard model as an informal modular theory with a limited range of validity. (shrink)

“'Ontological Mislocations', Modes of Conciousness and History: Indiscernibles, Displacement and Horizons of Possibility in the Philosophy of Arthur Danto”. In this article my purpose is to trace the links between three key elements in Arthur Danto’s philosophy: first, the capital consideration, for philosophical purposes, of human beings as ens representans , departing from the elucidation of a type of cognitive episode that Danto called “basic”. Secondly,I am concerned with the recurring appeal to a plane of consciousness that supports a dual (...) characterization in terms of the pair inside/outside and enables alogical space that is characteristic of philosophy as a reflective mode. Finally, I will treat a form of cognitive failure that Danto considered fundamental to the philosophical perspective, which leads to a specific type of restructuring of our ordinary system of beliefs. What I contend is that in Danto’s philosophical system these three elements become intelligible from the postulation of an effectual background that the author calls “objective historical structure”, which is characterized in terms of the horizons of possibility and impossibility that it delineates. These figures of historical-temporal possibility and impossibility constitute the matrix of historicity itself and also contribute decisively to shaping the permanent nucleus of dantean philosophical concerns.

What is a number? Answering this will answer questions about its philosophical foundations - rational numbers, the complex numbers, imaginary numbers. If we are to write or talk about something, it is helpful to know whether it exists, how it exists, and why it exists, just from a common-sense point of view [Quine, 1948, p. 6]. Generally, there does not seem to be any disagreement among mathematicians, scientists, and logicians about numbers existing in some way, but currently, in the mainstream (...) arena only definitions, descriptions of properties, and effects are presented as evidence. Enough historical description of numbers in history provides an empirical basis of number, although a case can be made that numbers do not exist by themselves empirically. Correspondingly, numbers exist as abstractions. All the while, though, these "descriptions" beg the question of what numbers are ontologically. Advocates for numbers being the ultimate reality have the problem of wrestling with the nature of reality. I start on the road to discovering the ontology of number by looking at where people have talked about numbers as already existing: history. Of course, we need to know not only what ontology is but the problems of identifying one, leading to the selection between metaphysics and provisional approaches. While we seem to be dimensionally limited, at least we can identify a more suitable bootstrapping ontology than mere definitions, leading us to the unity of opposites. The rest of the paper details how this is done and modifies Peano's Postulates. (shrink)

In terms of subject-centered philosophy of existential realism, the article discusses the ontological theories of George Berkeley and Bruno Latour, outlining and clarifying the conceptual relationship between the two. This relationship manifests itself: (a) in the attention that both paid to the issue of discreteness/continuity of matter and the limitations of its divisibility, (b) in their shared inclination toward nominalism and methodological affinity for the complementarity principle, (c) in an increased attention to weaker bonds of a correlation (coordination) type rather (...) than to strong bonds of determination type, (d) in linking the above orientations to the discussion of the ontological status of the subject, who first of all is human. G. Berkeley raises human subjectivity to a level that is as high as possible within the framework of religious idealistic philosophy. Such a position is achieved through several steps: through a postulate-based prohibition of infinite divisibility of matter and tabooing reduction of the macro-world to elements of the micro-world; through a sharp delimitation of the subject from everything the subject is not; through the hypothetical assumption of solipsism, which, in fact, always remains relative; through combining solipsistic nominalism and theistic realism based on the complementarity principle. However, B. Latour minimizes man’s personal agency. This paradigm is associated with a number of others: with the assumption of the infinite divisibility of matter, at least with reducing three dimensions to one, and macro-level to micro-level; with equalizing the subject and the non-subject, humans and non-humans; with his caution to an individual as an opponent of democracy; with combining scientist nominalism and technologism of the actant-rhizome network based on the complementarity principle. Latour’s claims to non-trivial materialism and realism, if he has them, are inconsistent. An existential realist is likely to define his ontology as technologically desubjectified Berkeleianism.

It is almost universally believed that in quantum theory the two following statements hold: all transformations are achieved by a unitary interaction followed by a von-Neumann measurement; all mixed states are marginals of pure entangled states. I name this doctrine the dogma of purification ontology. The source of the dogma is the original von Neumann axiomatisation of the theory, which largely relies on the Schrődinger equation as a postulate, which holds in a nonrelativistic context, and whose operator version holds (...) only in free quantum field theory, but no longer in the interacting theory. In the present paper I prove that both ontologies of unitarity and state-purity are unfalsifiable, even in principle, and therefore axiomatically spurious. I propose instead a minimal four-postulate axiomatisation: associate a Hilbert space \ to each system \; compose two systems by the tensor product rule \; associate a transformation from system \ to \ to a quantum operation, i.e. to a completely positive trace-non-increasing map between the trace-class operators of \ and \; evaluate all joint probabilities through that of a special type of quantum operation: the state preparation. I then conclude that quantum paradoxes—such as the Schroedinger-cat’s, and, most relevantly, the information paradox—are originated only by the dogma of purification ontology, and they are no longer paradoxes of the theory in the minimal formulation. For the same reason, most interpretations of the theory interpret the same dogma, not the strict theory stripped of the spurious postulates. (shrink)

In this paper, I argue that there is an inconsistency between two presentist doctrines: that of ontological symmetry and asymmetry of fixity. The former refers to the presentist belief that the past and future are equally unreal. The latter refers to the A-Theoretic intuition that the past is closed or actual, and the future is open or potential. My position in this paper is that the presentist is unable to account for the temporal asymmetry that is so fundamentally a part (...) of her theory. In Section I, I briefly outline a recent defence of presentism due to Craig, and argue that a flaw in this defence highlights the tension between the presentist's doctrines of ontological symmetry and asymmetry of fixity. In Section II, I undertake an investigation, on the presentist's behalf, in order to determine whether she is capable of reconciling these two doctrines. In the course of the investigation, I consider different asymmetries, other than that of ontology, which might be said fundamentally to constitute temporal asymmetry, and the asymmetry of fixity in particular. In Section III, I also consider whether the presentist is able to avail herself of some of the standard B-Theoretic accounts of the asymmetry of fixity, and argue that she cannot. Finally, I conclude that temporal asymmetry cannot be accounted for (or explained) other than through the postulation of an ontological asymmetry. (shrink)

This paper defends two claims about the criterion of commitment of W.V.O Quine. The first claim is that the criterion can be made extensional. The second is that a proper formulation becomes an analytic truth. We spend a few preliminary sections clarifying our intended notion of ontological commitment. We will not go very far in our investigation of the criterion if we do not distinguish the things a theory postulates, what its adherents, or anybody else, believe in, and which of (...) these entities we have compelling reasons to accept. A look at [Quine 1953] shows that the criterion concerned the postulation of entities by theories, but it is often misread as an attempt to say something about either or. The core of the paper is an exposition of two formulations of the criterion. I first state a schema improving on that of [Scheffler and Chomsky 1959]. The second formulation is a single principle and construes commitment as a relation between theories and predicates: ontological commitment to the entities that satisfy a given predicate. Both criteria are extensional and are formulated for constructional systems, in the sense of [Carnap 1928] and [Goodman 1951], rather than for theories construed as interpreted sets of sentences. This solves a problem raised by [Halvorson 2019]. Their analyticity is substantiated by showing that their most controversial consequences are instances of Tarski’s Convention. (shrink)

FAR FROM BEING A PURELY ESOTERIC CONCERN of theoretical mathematicians, the examination of the ontological status of mathematical entities, I submit, has far-reaching implications for a very practical area of knowledge, namely, the method of science in general, and of physics in particular. Although physics and mathematics have since Newton's second derivative been inextricably wedded, modern physics has a particularly mathematical dependence. Physics has moved and continues to move further away from the possibility of direct empirical verification, primarily because of (...) the increasingly complex logistical problems of experimentation within the parameters of the very large and of the very small. As certain areas become more and more theoretical, with developments of this century in astrophysics, cosmology, and quantum mechanics, and more specifically, with the postulation of new hypothetical elementary particles based almost exclusively upon mathematical data, physics is forced to depend increasingly upon mathematics as a method for verifying physical possibility. Typically, a mathematical formulation descriptive of an empirically established phenomenon x is manipulated and made subject to derivation on the assumption that the new formulation will continue to correspond with physical reality, and may even yield new information about the phenomenon's behavior. Why, however, should a coherence between the empirically-defined world and mathematical processes be assumed? This coherence is, above all, dependent upon a hidden metaphysically strong presupposition about the ontological status of mathematical entities and their systems. (shrink)

In recent work, the interrelated questions of whether there is a fundamental level to reality, whether ontological dependence must have an ultimate ground, and whether the monist thesis should be endorsed that the whole universe is ontologically prior to its parts have been explored with renewed interest. Jonathan Schaffer has provided arguments in favour of 'priority monism' in a series of articles (2003, 2004, 2007a, 2007b, forthcoming). In this paper, these arguments are analysed, and it is claimed that they are (...) not compelling: in particular, the possibility that there is no ultimate level of basic entities that compose everything else is on a par with the possibility of infinite 'upward' complexity. The idea that we must, at any rate, postulate an ontologically fundamental level for methodological reasons ( Cameron 2008 ) is also discussed and found unconvincing: all things considered, there may be good reasons for endorsing 'metaphysical infinitism'. In any event, a higher degree of caution in formulating metaphysical claims than found in the extant literature appears advisable. (shrink)

The notions of ground and ontological dependence have made a prominent resurgence in much of contemporary metaphysics. However, objections have been raised. On the one hand, objections have been raised to the need for distinctively metaphysical notions of ground and ontological dependence. On the other, objections have been raised to the usefulness of adding ground and ontological dependence to the existing store of other metaphysical notions. Even the logical properties of ground and ontological dependence are under debate. In this article, (...) I focus on how to account for the judgements of non-symmetry in several of the cases that motivate the introduction of notions like ground and ontological dependence. By focusing on the notion of explanation relative to a theory, I conclude that we do not need to postulate a distinctively asymmetric metaphysical notion in order to account for these judgements.

Our purpose in this paper is to delineate an ontology for quantum mechanics that results adequate to the formalism of the theory. We will restrict our aim to the search of an ontology that expresses the conceptual content of the recently proposed modal-Hamiltonian interpretation, according to which the domain referred to by non-relativistic quantum mechanics is an ontology of properties. The usual strategy in the literature has been to focus on only one of the interpretive problems of (...) the theory and to design an interpretation to solve it, leaving aside the remaining difficulties. On the contrary, our aim in the present work is to formulate a “global” solution, according to which different problems can be adequately tackled in terms of a single ontology populated of properties, in which systems are bundles of properties. In particular, we will conceive indistinguishability between bundles as a relation derived from indistinguishability between properties, and we will show that states, when operating on combinations of indistinguishable bundles, act as if they were symmetric with no need of a symmetrization postulate.

We analyze axioms and postulates as speech acts. After a brief historical appraisal of the concept of axiom in Euclid, Frege, and Hilbert, we evaluate contemporary axiomatics from a linguistic perspective. Our reading is inspired by Hilbert and is meant to account for the assertive, directive, and declarative components of modern axiomatics. We will do this by describing the constitutive and regulative roles that axioms possess with respect to the linguistic practice of mathematics.

In this paper, we examine the meta-ontology of AI systems with human-level intelligence, with us denoting such AI systems as AI E. Meta-ontology in philosophy is a discourse centered on ontology, ontological commitment, and the truth condition of ontological theories. We therefore discuss how meta-ontology is conceptualized for AI E systems. We posit that the meta-ontology of AI E systems is not concerned with computational representations of reality in the form of structures, data constructs, or (...) computational concepts, while the ontological commitment of AI E systems is directed toward what exists in the outside world. Furthermore, the truth condition of the ontology (which is meta-ontological assumption) of AI E systems does not require consistency with closed conceptual schema or ontological theories but rather with reality, or in other words, “what is the world” (Smith, 2019, p.57). In addition, the truth condition of AI E systems is verified through operational success rather than by coherence with theories. This work builds on ontological postulates about AI systems that were formulated by Brian Cantwell Smith (2019). (shrink)

Recently Slavoj Žižek has critiqued certain "feminist" readings of Lacan's feminine structure of desire, including Julia Kristeva, for postulating a feminine discourse which is supposedly beyond the phallic economy. This paper defends Kristeva's position, both by noting how Žižek Hegelian ontology prevents him from utilizing the resources of sexual difference and by clarifying Kristeva's double account of maternity. One consequence of this investigation is that a Kristevean theory of desire will provide one with a new form of political intervention (...) by isolating sites of resistence that Žižek disavows. Another consequence is a refiguration of "feminist" psychoanalytic practice. (shrink)

Quine has developed two reasons for thinking that our ontology should not include the ontological category of properties. His first point is that the criterion for individuating properties is unclear, and the second is that postulating the existence of properties would not explain anything. In what follows I critically examine these two themes, which I will call the clarity argument and the parsimony argument. Although I will suggest that these two arguments are defective, I also will try to show (...) that certain related arguments on behalf of the existence of properties are likewise flawed. This will set the stage for the discussion in the fourth section of the perspective provided by evolutionary theory on the question of the ontological status of properties. It will emerge that evolutionary theory provides reason for thinking that properties exist, and, additionally, gives an interesting point of view on the epistemological and metaphysical issues that Quine has addressed.

This long paper (19 pages; about 7,000 words) is a trenchant critique of the first half of David Norton’s 1982 book David Hume: Common Sense Moralist, Sceptical Metaphysician. Norton claims that both Hutcheson and Hume were ‘moral realists’, and imputes to them an inflated moral ontology at sharp variance with what they actually wrote. Indeed, Norton’s interpretation is sustainable only when the texts are grossly misrepresented by paraphrases which say the opposite of what the authors actually wrote. The paper (...) concludes: I agree that Hutcheson and Hume were opposed to nihilistic scepticism, but maintain that their conception of morality was essentially a psychological one, free from metaphysical postulates of any supra-sensory or non-natural moral reality. Therefore, to call them moral realists is misleading. In view of the misunderstandings, misrepresentations, ambiguities, and contradictions which pervade Norton’s arguments, his attempt to establish that there were moral realists must be counted unsuccessful.

Political methodologists have long sought to develop standards that can guide political scientists in the process of concept formation. Yet, the methodology literature has struggled to provide satisfactory solutions to the fundamental problem of conceptualization: for any given concept, there are a large number of attributes one could postulate as its defining characteristics, and it is unclear how to adjudicate between different possible definitions. We leverage the fact that the theory within which a concept appears places important restrictions on concept (...) formation: conceptualizations entail ontological claims that need to be consistent with those of the theories in which they appear.

I have been interested for quite some time in the relevance of reference to ontology. Another who has shown equal interest is W. V. Quine. Surprisingly, because of many other disagreements, there is a large area in which we agree about reference and ontology, namely, that there is some reason to think that both are “inscrutable.” Not so surprisingly, there is a crucial point where we disagree, namely, concerning the relativity of reference and ontology. Although it is (...) not clear, it seems that Quine holds that both reference and ontology are relative to what he calls a “background language” in a way that results in metaphysical questions, as I describe them, being senseless or meaningless. He argues for this relativity from inscrutability. I, however, explain it by postulating that ontological problems and certain referential problems are in a certain sense, “external.” In this paper I propose to lay out what I take to be the relevance of reference to ontological problems, show where Quine’s claims of inscrutability agree with my view, clarify Quine’s claims about relativity, and finally show that, given the inscrutability we both find acceptable, it is reasonable to reject the relativity only Quine accepts.

This article defends linguistic descent in contrast to the possibility of linguistic ascent or the formal mode in metaphysics. We can go both ways, but metaphysics metaphysically defined presupposes metaphysics conceptualstically defined, which presupposes metaphysicas ontologially defined. Predicates implie abstract concepts (categories in metaphysics), and abstract oncepts presuppose the concrete qualities from which they are abstracted. A distinction is made between any quality and that which has the quality. This article contains a refutation of Kant on the ontological argument. Being, (...) conceived as instantiation, is a predicate once we posit universal properties instantiated by whatever is. The article, in the author's subequent work, leads to an explicit nominalism which asserts universals only as practical postulates of theoretical reason, i.e., logical discourse. Qualities are unique, not open to multiple instantiation. (shrink)

We propose the conjecture according to which the fact that quantum mechanics does not admit sharp value attributions to both members of a complementary pair of observables can be understood in the light of the symplectic reduction of phase space in constrained Hamiltonian systems. In order to unpack this claim, we propose a quantum ontology based on two independent postulates, namely the phase postulate and the quantum postulate. The phase postulate generalizes the gauge correspondence between first-class constraints and gauge (...) transformations to the observables of unconstrained Hamiltonian systems. The quantum postulate specifies the relationship between the numerical values of the observables that permit us to individualize a physical system and the symmetry transformations generated by the operators associated to these observables. We argue that the quantum postulate and the phase postulate are formally implemented by the two independent stages of the geometric quantization of a symplectic manifold, namely the prequantization formalism and the election of a polarization of pre-quantum states respectively.

I contend that Kant’s moral argument that postulates God and an afterlife in order to justify moral rationality counts strongly in favor of theistic ethics even though it cannot on its own justify that God exists. In moving toward this conclusion, I assess Kant’s moral argument and note how both Kant and the utilitarian Henry Sidgwick, in their own ways, recognize that morality cannot reasonably be seen as completely overriding if God and an afterlife are rejected. I then critique a (...) theistic moral rationality argument offered by C. Stephen Layman, as a flaw in this argument helps to reveal why arguments centering upon moral rationality likely cannot reach an ontological conclusion concerning theism; nevertheless, I contend that moral rationality arguments like Kant’s have apologetic significance for theism. They reveal a dilemma for secular ethics: either appeal to the possibility of theism in order to justify moral rationality or else accept that morality is not fully rational. (shrink)

The notion of so-called "postulated ontology" appears in the context of a well- -known thesis of the underdetermination of scientific theories by empirical data. It is argued in the paper, that the conviction of the existence of some kind of relation between a given theory and ontological ideas can be derived from this thesis, regardless of its particular form. Therefore, certain solutions to classical philosophical questions can be obtained, in principle, by careful inspection of scientific achievements. However, if (...) the thesis of underdetermination holds, such philosophical solutions are not imposed by science itself. In order to arrive at some kind of ontology based on science, it seems necessary to accept certain philosophical presuppositions in the first place. This, and the fact that scientific theories change in time show that although such a kind of ontology is possible, and perhaps desirable, it can never be ultimate. (shrink)

We propose a new quantum ontology, in which properties are the fundamental building blocks. In this property ontology physical systems are defined as bundles of type-properties. Not all elements of such bundles are associated with definite case-properties, and this accommodates the Kochen and Specker theorem and contextuality. Moreover, we do not attribute an identity to the type-properties, which gives rise to a novel form of the bundle theory. There are no “particles” in the sense of classical individuals in (...) this ontology, although the behavior of such individuals is mimicked in some circumstances. This picture leads in a natural way to the symmetrization postulates for systems of many “identical particles”. (shrink)

In the correspondence with Clarke, Leibniz proposes to construe physical theory in terms of physical (spatio-temporal) relations between physical objects, thus avoiding incorporation of infinite totalities of abstract entities (such as Newtonian space) in physical ontology. It has generally been felt that this proposal cannot be carried out. I demonstrate an equivalence between formulations postulating space-time as an infinite totality and formulations allowing only possible spatio-temporal relations of physical (point-) objects. The resulting rigorous formulations of physical theory may be (...) seen to follow Leibniz' suggestion quite closely. On the other hand, physical assumptions implicit in the postulation of space-time totalities are made explicit in the reconstruction of the space-time versions from the physical-relation versions.

An epistemological interpretation of quantum mechanics hinges on the claim that the distinctive features of quantum mechanics can be derived from some distinctive features of an observational basis. Old and new variations of this theme are listed. The program has a limited success in non-relativistic quantum mechanics. The crucial issue is how far it can be extended to quantum field theory without introducing significant ontological postulates. A C*-formulation covers algebraic quantum field theory, but not the standard model. Julian Schwinger’s anabatic (...) methodology extended a strict measurement-based formulation of quantum mechanics through field theory. His extension also excluded the quark hypothesis and the standard model. Quarks and local gauge invariance are postulates that go beyond the limits of an epistemological interpretation of quantum mechanics. The ontological significance ascribed to these advances depends on the role accorded ontology. (shrink)

[EN] Several conceptions of trope bundles have postulated mutual relations of ontological dependence to explain the unity of the bundle. The idea is that a bundle is a plurality of tropes such that each one of them is dependent on any other. A variant of this idea is that there is a ‘nucleus’ of tropes all of them mutually dependent, and there is also a ‘periphery’ or ‘halo’ of tropes that are dependent on the tropes of the nucleus, but (...) the tropes of the nucleus are not dependent on them. There are several theoretical advantages that trope bundles conceived in this way have. A weakness of the position nevertheless is that it requires an equivalence relation of dependence. But it has been normally supposed that dependence is a strict order, i.e. it is relation irreflexive, asymmetric and transitive. Several recent works have put into question this traditional assumption. Those recent criticisms are discussed and it is argued that they are not convincing. Further arguments are presented for the irreflexivity and transitivity of dependence, from which asymmetry follows. Dependence, then, appears to be in fact a strict order. This implies that most forms of nuclear trope bundles are unintelligible. But not all of them, because nuclear tropes with a unique nuclear trope are coherent. [ES] Varias concepciones de cúmulos de tropos han postulado relaciones de dependencia ontológica mutuas para explicar la unidad del cúmulo. La idea es que un cúmulo es una pluralidad de tropos tal que cada uno de ellos es dependiente de cualquier otro. Una variante de esta idea es que hay un ‘núcleo’ de tropos todos ellos mutuamente dependientes y hay también una ‘periferia’ o ‘halo’ de tropos que son dependientes de los tropos del núcleo, pero los tropos del núcleo no son dependientes de ellos. Hay varias ventajas teóricas que tienen los cúmulos de tropos concebidos de este modo. Una debilidad de esta posición, sin embargo, es que requiere una relación de dependencia que sea una relación de equivalencia. Pero se ha supuesto normalmente que la dependencia es un orden estricto, esto es, una relación irreflexiva, asimétrica y transitiva. Varios trabajos recientes han puesto en cuestión este supuesto tradicional. Estas criticas recientes son aquí discutidas y se argumenta que no son convincentes. Se presentan argumentos adicionales para la irreflexividad y la transitividad de la dependencia, de lo que se sigue la asimetría. Entonces, la dependencia resulta ser un orden estricto. Esto implica que la mayoría de las formas de cúmulos nucleares de tropos son ininteligibles. Pero no todos, porque los cúmulos nucleares con un único tropo nuclear son coherentes. (shrink)

A simple argument against Lewisian modal realism as portrayed in On the Plurality of World arises from its treatment of doxastic modalities. It is easily shown that if it is true, it is impossible to doubt the theory on ontological grounds, or, that, if it is possible to maintain doubt about modal realism’s existential postulate, it has to be false. The argument hinges on the fact that modal realism’s main ontological hypothesis, if true, is necessarily true.

In the Critique of Pure Reason, following his elucidation of the ‘postulates’ of possibility, actuality, and necessity, Kant makes a series of puzzling remarks. He seems to deny the somewhat metaphysically intuitive contention that the extension of possibility is greater than that of actuality, which, in turn, is greater than that of necessity. Further, he states that the actual adds nothing to the possible. This leads to the view, fairly common in the literature, that Kant holds that all modal categories, (...) in their empirical applications, are coextensive. I diverge from the common view. First, Kant is not committed to the coextensiveness thesis, understood as above. Instead, he espouses a weaker, epistemological version of the coextensiveness thesis, namely that what we can assert to be really possible is coextensive with what we cognize to be actual. Second, Kant's remarks are not intended to introduce a positive ontological thesis about the extensions of modal categories. Rather, he means to criticize a certain conception of modalities that was prevalent among his rationalist predecessors, i.e., the conception of modalities as various determinations that enter the intensions of concepts of things.

Applied technological developments are represented by (1) genetic engineering as management tools of biological evolution and (2) socio-economic engineering as management tools of civilizational and socio-cultural development. This binary structure logically follows from the postulated three-module organization of the sustainable evolutionary strategy of the sentient human being. Naturphilosophy once again acquires the status of the basis of the theory of evolution in an explicit way. There is a system of metaphysical postulates and ontological categories derived from the anthropic principle (...) of participation. For modern neoliberal political democracy, bio-power and biopolitics look like the most effective technology for stabilizing the scenarios and trends of the global evolutionary process that are optimal within this ideological system. Conclusions.Transbipolitics in our understanding is a political problematic related to the rationalization of the global evolutionary process. In the coming decades transbipolitics will become the carrier element of the global process of evolution of the noosphere with the consequent complication and increase of cohesion between the individual socio-cultural types that are part of the system of modern globalizing civilization.

In a pragmatic approach to ontology, what is necessary and sufficient for the dispositional causation of events is interpreted realistically, and postulated to exist. This leads to a concept of `generic substance' (Aristotle's underlying `matter') as being constituted by dispositions, not just being the `bare subject' for those dispositions. If we describe the forms of objects according their spatiotemporal range, then this form is best viewed as a field, and substances themselves are best conceived as `fields of propensity'.

The author presents a version of the ontological scheme of Newton’s mechanistic worldview based on both the study of previous versions of its understanding and the text of the “Mathematical Principles of Natural Philosophy”. Newton developed a model of new universality or a homogeneous and isotropic world in which uniform laws operate. This model is based on several ontological postulates Newton introduced, which can be isolated from several provisions of his classic work. The new mechanistic worldview is based on the (...) imputation of the world of universal simplicity. The quantitative “unit” of a simple, homogeneous, physical-geometric universe is an ambivalent corpuscle-point. The main constants of the “mechanistic universe” are the diversity of the numbers of masses, motions, and forces connected by clear reciprocal relationships. Newton also introduced theoretical space and time as a privileged, absolute reference system. Finally, in the Newtonian version of the mechanistic worldview, there are compelled metaphysical ingredients or inexplicable and transcendental qualities. They are gravity, ether, and God. Thus, the ontological scheme of Newton’s mechanistic worldview is a construction based on the sequential mental experiment of presenting the universe exclusively from the side of its “objectivity” and “sensory certification”.

Several metaphysical debates have typically been modeled as oppositions between a relationist approach and a substantivalist approach. Such debates include the Bundle Theory and the Substratum Theory about ordinary material objects, the Bundle (Humean) Theory and the Substance (Cartesian) Theory of the Self, and Relationism and Substantivalism about time. In all three debates, the substantivalist side typically insists that in order to provide a good treatment of the subject-matter of the theory (time, Self, material objects), it is necessary to postulate (...) the existence of a certain kind of substance, while the other side, the relationist one, characteristically feels that this is an unnecessary expense and that one can get the job done in an ontologically cheaper way just with inter-related properties or events. In this paper I shall defend the view that there is much less of a disagreement between relational ontologies and substantival ontologies than it is usually thought. I believe that, when carefully examined, the two sides of the debate are not that different from each other, in all three cases of pairs of views mentioned above. As we will see, both the relational side and the substantival side work in the same way, suffer from and answer the same objections, and are structurally extremely similar. It will be an important question – one that I shall discuss in detail, and that is indeed the main point of interest for me in this paper – whether this means that the two sides of the debate are somehow 'equivalent' or not, and what 'equivalent' could mean.

Among the two rival views on the outside world, preference was historically given to the substantial point of view. The success of Aristotle’s logic was due to the simple substantial ontology built by him. In that logic, the subject is characterized by an instant set of properties. The change of objects leads to the change of properties. The reduction of processes to substances causes a number of problems. The construction of procedural logic should be started with the construction of (...) the most abstract procedural ontology. The main difference of processes from substances is their extension. Each item, as a process, can be considered as a bundle of parallel processes. The relation the individual S has the property P is the main relation in the substantial ontology. In the procedural ontology, one of the main ones is the relation process R is a sub-process of the process Q. This relation is sufficient for the interpretation of the main syllogistic constants. As a result, we get Łukasiewicz syllogistic for reasoning about parallel processes. The extension of the processes allows us to talk about their parts. The second main relation of procedural ontology is the relation process P consists of two successive processes Q and R. If the processes Q and R are successive, it is natural to make use of the relation earlier-later. In procedural ontology, time does not emerge through external postulation but exists within it. In the ontology of processes, one can naturally define the concept of causality, which becomes a logical concept. However, the success of the procedural view of the outside world is only possible if the new ways of reasoning prove to be a more effective tool for intellectual cognitive activity than the existing ones.

John Searle has recently developed a theory of reasons for acting that intends to rescue the freedom of the will, endangered by causal determinism, whether physical or psychological. To achieve this purpose, Searle postulates a series of "gaps" that are supposed toendowthe self with free will. Reviewing key steps in Searle's argument, this article shows that such an undertaking cannot be successfully completed because of its solipsist premises. The author argues that reasons for acting do not have a subjective, I- (...) class='Hi'>ontology but a first-person plural, Weontology that better accounts for agency and responsibility. Key Words: free will • agency • reasons for acting • ontology. (shrink)

In the paper, I distinguish between the semantic and the “direct” approach to event ontology. The first approach, employed by D. Davidson, starts with logical analysis of natural language. This analysis uncovers quantification over the domain of events. Thus, we have ontological commitment to events and, at the same time, also a suggestion of how to view their nature. The second approach, used by J. Kim and D. Lewis, deals with events “directly”, i.e. not by analyzing language first. Events (...) are postulated because they are useful in other theories and their nature is adjusted to the needs of these theories. In the paper, I analyze both approaches and outline their problems and advantages. I conclude that we should conditionally prefer the latter approach on methodological grounds. This preference is based on the assumption that submitting hypotheses to tests seems to be a crucial part of metaphysical methodology. Since the “direct” approach to event ontology allows for more testing, it should be preferred over the semantic approach. (shrink)

Relational ontologies that postulate the primacy of relations over their relata may seem like a contrary and incompatible approach to object-oriented ontology (OOO). Therefore, this paper aims to clarify the relationship between Barad’s and Escobar’s relational ontologies and Harman’s OOO by comparing and contrasting the relative coherences between them. After outlining the central assumptions of the different accounts, I discuss the problems of relational ontologies with regard to several ethical, political, and posthumanist issues. I argue that OOO is able (...) to avoid their pitfalls without rejecting the major benefits of relational ontologies. After a critique of the pluralization of worlds within relational ontologies, I argue for the rejection of the concept of world(s) in favor of understanding space and time as emerging from polar tensions within the quadruple objects. Consequently, this highlights the potential of OOO to encounter the Anthropocene beyond scientific realism and to account for the plurality of reality without granting any hegemonic access to it. This paper, therefore, argues for a conceptualization of ontological difference without one or many worlds. (shrink)

This dissertation argues that on the basis of their elaboration of and appeal to the Virtual, Henri Bergson and Gilles Deleuze operate a profound transformation of the Kantian conception of the transcendental. This implies a novel account of experience and its conditions, resulting in what I call Transcendental Experience---whereby the primary condition of experience, that is, time, becomes immanent to what it conditions. Through this revaluation of the transcendental, Bergson and Deleuze are ultimately providing us with an alternative to both (...) Kant's and Phenomenology's theories of subjectivity. Rooted in real experience rather than abstract forms, this approach points to the primacy of the unconscious over consciousness as the ground of subjectivity. With Bergson and Deleuze, then, it is ultimately to the ontological unconscious that we must refer thought and experience, thereby accounting for a radically novel conception of subjectivity, in terms of inhuman and inorganic difference or alteration rather than some postulated transcendental ego. ;Hoping to provide a contribution to the current scholarship concerning Bergson and Deleuze, I examine closely both what they have in common and where they diverge. Accordingly, I dedicate the first part of the dissertation to a comprehensive examination of Bergsonian metaphysics. I conclude that through his observation of the immediate data of consciousness, perception and memory in terms of concrete duration, he is able to offer a new philosophical method based in an original notion of intuition---a method which, I claim, eventually allows him to solve the problem of dualism. The second part of this project then turns to an examination of Deleuze's Transcendental Empiricism which, I argue, is directly inspired from Bergson's method of intuition. There, I focus on Deleuze's differential ontology, which leads me to an exploration of the role he ascribes to the Sensible, and consequently, to the artistic experience, as the primary ground---which, he shows, is also an ungrounding---of consciousness. Finally, I argue that over and above Bergson's ultimate privileging of continuity, Deleuze's prioritization of discontinuity allows him to address the great traditional philosophical problems while opening the future for thought and experience.

It has been argued that in the context of Bohm’s approach to quantum mechanics, the postulation of a three-dimensional ontology (as opposed to a high-dimensional one) is presumed to be the only interpretation that may reliably support object-oriented realism by virtue of the fact that this ontology is approximately preserved through scientific change, at least in the classical–quantum transition. Based on an interpretative analysis of the Bohmian formulation, I shall critically evaluate the tenability of this argument. In so (...) doing, I shall argue that this formulation admits the postulation of an alternative ontology that is properly defined in a high-dimensional space, and is approximately preserved among this transition. As a result, both the three-dimensional and the high-dimensional worldviews shall form the basis of an equally reliable endorsement of object-oriented realism in the context of the Bohmian framework. I shall conclude that this argument becomes a problem of metaphysical underdetermination between a three and a high-dimensional Bohmian interpretation. (shrink)

Spontaneous collapse theories provide a promising solution to the measurement problem. But they also introduce a number of problems of their own concerning dimensionality, vagueness, and locality. In response to these problems, advocates of collapse theories have proposed various accounts of the primitive ontology of collapse theories—postulated underlying entities governed by the collapse theory and underwriting our observations. The most prominent of these are a mass density distribution over three-dimensional space, and a set of discrete “flash” events at (...) space-time points. My argument here is that these primitive ontologies are redundant, in the sense that the structures exhibited by the primitive ontologies that allow them to solve the problems facing spontaneous collapse theories are also present in the wave function. But redundancy is not nonexistence; indeed, the fact that the relevant structures are already there in the wave function shows that the mass density ontology and the flash ontology exist whether they are explicitly postulated or not. By the same token, there is no need to decide between a wave function ontology, a mass density ontology and a flash ontology. (shrink)

The standard interpretation of Avicenna's correspondence theory of truth posits that propositions either correspond to what exists extramentally or otherwise their truthmaker is mental existence. An influential post-Avicennian philosopher, Naṣīr al-Dīn Ṭūsī (d. 1274) points to the insufficiency of the above division of propositions and their respective truthmakers. He mentions the possibility of conceiving false propositions, such as ‘One is not half of two’ and postulates the necessity of the existence of another truthmaking domain for their true counterparts which he (...) calls nafs al-amr. It is where objective and timeless entities, such as mathematical propositions, are located. While some claim that Ṭūsī's identification of this domain with the first Separate Intellect is a testimony to his Avicennian convictions, Ṭūsī's solution is a conspicuous departure from Avicenna that not only helps him remedy the insufficiency of Avicenna's theory of truth but is consistent with his critique of Avicenna's theory of God’s knowledge.

The purpose of this essay is to formulate a sociological critique of the concept of scarcity in mainstream economics by synthesising necessary conceptions in the construction of a theoretical structure with greater explanatory power than the current mainstream articulation. Mainstream economics asserts the universality of scarcity. A critical scrutiny of this assertion is conducted by discussing the empirical phenomenon of global hunger in relation to a theoretical elaboration of the concepts of scarcity and abundance. The historical origins of the scarcity (...) postulate is traced to the work of Carl Menger. The concern of global hunger shows that there is abundance of food goods, but still frustration of human needs occurs. An alternative approach is developed through a theoretical synthesis of Menger, Amartya Sen and critical realism, which asserts an ontologically stratified, differentiated and geo-historically conditioned understanding of scarcity and abundance. It is proposed that this approach is more fruitful than the scarcity postulate in explaining the process and conditions of frustration and satisfaction of human needs. Merely postulating scarcity tends to veil the underlying causes of poverty in general and hunger in particular. Central implications of the new model for socioeconomic analysis are considered.
