David Lewis is typically interpreted as a class nominalist. One consequence of class nominalism, which he embraced, is that the reduction of ordered pairs, triples, etc to unordered sets of sets is conventional. The reaction by his Australian counterparts D.M. Armstrong and Peter Forrest was that Lewis was not being ontologically serious. This chapter evaluates this debate over serious ontology. It is argued that in one sense Lewis is ontologically serious, but that his additional commitment to (...) structuralism about classes should push him to adopt a trope-theoretic account of naturalness, which opens up another way to respond to the charge of not doing serious ontology. This conclusion is supported by certain remarks he makes in his correspondence, thus revealing how his thinking about properties appears to have evolved from property-egalitarianism to a sparse theory of tropes.

The paper first argues that if one takes current fundamental physics seriously, one gets to a metaphysics of events and relations in contrast to substances and intrinsic properties. Against that background, the paper discusses Heil’s theory of properties being both categorical and dispositional and his rejection of levels of being. I contrast these views with a Humean metaphysics. My concluding claim is that Heil’s account of properties opens up the perspective of a conservative reductionism, which avoids the common reservations against (...) reductionism. (shrink)

This paper builds on some important recent work by Amie Thomasson, wherein she argues that recent disputes about the existence of ordinary objects have arisen due to eliminiativist metaphysicians’ misunderstandings. Some, she argues, are mistaken about how the language of quantification works, while others neglect the existence and significance of certain analytic entailments. Thomasson claims that once these misunderstandings are cleared away, it is trivially easy to answer existence questions about ordinary objects using everyday empirical methods of investigation. She reveals (...) how two conflicting metaontologies can lead to different positions in the first-order debate. In this paper, I bring a third metaontological perspective to the table: one that enables us to maintain that ontological disputes about ordinary objects are not trivially easy to settle, even if we agree with Thomasson that they are merely verbal. These are serious verbal disputes. (shrink)

This paper aims at discussing the usage by Davidson as to events of Quine's criterion of ontological commitment. According to Davidson, we are ontologically committed to the existence of events as individuals as we employ literally terms such as ‘Caesar’s death’, for instance. Davidson extends this analysis to actions as well, since actions are human events. One of the consequences of this view is that psychology deals with individual events in a non-lawful way. An alternative view is here proposed, based (...) on a complementary criterion, namely ontological density, according to which from the point of view of a given theory, we can always distinguish between events (or phenomena) and individuals (entities) among the overall occurrences described by the theory. Some consequences of this alternative view of psychology as a science dealing lawfully with general human events are also explored here. (shrink)

I don’t know whether undead beings exist. I also think it is an open question whether anyone is evil in, say, the way bad guys are depicted in supernatural horror films and serial killer movies. I do think it’s nevertheless puzzling that the undead are frequently portrayed as evil in that way. I’m inclined to think that if we were to stumble across any undead they would be less likely to be evil than any random live person we stumble across. (...) Consider this a call for some undead understanding. I am going to approach these conclusions in a roundabout way. First, I’ll try to sketch something of an ontology of the undead, an account of their nature and variety. Then, I’ll show how these considerations should change how we think about the undead and their purported propensity for evil. (shrink)

Linguistic ontologists and antilinguistic, ‘serious’ ontologists both accept the inference from ‘Fido is a dog’ to ‘Fido has the property of being a dog’ but disagree about its ontological consequences. In arguing that we are committed to properties on the basis of these transformations, linguistic ontologists employ a neo-Fregean meta-ontological principle, on which the function of singular terms is to refer. To reject this, serious ontologists must defend an alternative. This paper defends an alternative on which the function (...) of singular terms is not generally to refer and on which they are generally ontologically noncommittal. This is the best way to reject linguistic, ‘easy’ arguments for the existence of properties. The account recommends neutralism about quantification (drawing on Barcan Marcus and Meinongianism), coherently bringing together two important yet uncombined meta-ontological movements. Moreover, it employs Ramseyan insights about the transformations to provide a nonreductionist, non-error-theoretic redundancy approach to explicit talk about properties. (shrink)

My concern is to overturn the Leibnizean model of God's creation of the world which proposes that God selected a possible world out of a whole host of other alternative ones. This is the familiar possible worlds model of creation. I argue that this understanding of creation does not take seriously the idea of ex nihilo and that, rather than considering determinate possible worlds, we should understand possibility as indeterminate. I then develop this argument and explores how it impacts on (...) the idea of providence, and the problem of evil. I then explore the notion of creativity. Only a God who can make something utterly novel is a God who is making something different from Himself and which consequently has no divine precedent. A God who uses possible worlds makes nothing new. -/- . (shrink)

Mainstream psychologists have not only ignored the unique and radical character of practice; they have generally misunderstood it. A major reason for this ignorance and misunderstanding is mainstream psychology's assumption of a particular ontology--abstractionism. With abstractionism, psychologists have generally assumed that abstractions, such as theories, techniques, and principles, capture and embody the fundamentally real. Most pertinently, abstractions are believed to precede and lay the foundation for good and thoughtful practice. Indeed, practices do not exist, in an important ontological sense, (...) except in relation to the concrete and particular situations and cultures that give rise to them, implying what we might call a relational ontology. The purpose of this article is to explore the possible meanings and implications of a relational ontology for psychology. I first attempt to clarify the important features of relational conceptions in general, distinguishing most importantly between their weak and strong forms. Then, I situate strong or ontological relationality historically by describing its initial embrace and eventual rejection by early scientists. To bring these historical lessons into the present, ontological relationality is next compared to the abstractionist understandings of the real and fundamental in mainstream psychology. These two forms of ontology are then illustrated by exploring their contrasting implications for individual and community identity. 2012 APA, all rights reserved). (shrink)

This paper investigates Alfred North Whitehead and Maurice Merleau-Ponty’s attempts to develop a historical, dynamic ontology (a “process ontology”, according to the former, and an “ontology of the flesh” for the latter). The claim of the paper is that their originality lies in the methods adopted to reach such ontologies, which show strong similarities. Both authors based their research on nature, conceived of as “the leaf of Being”, and on perceptual experience, understood not as a chaos of (...) bare, punctual, sense data, but as the complex, original source of meaning that constitutes the primary field of philosophical investigation—the only source from which one can gain new understanding of both nature and logos (things, happenings, values, subjectivity, laws, etc.). After some introductory remarks on the connections between Whitehead and Merleau-Ponty, the paper is divided into three parts. The first part clarifies why and how, according to the philosophers, ontology should start from a new scrutiny of nature. The second part specifies what this new conception of nature, based on perceptual experience, is. The third part focuses on how their ontologies must be construed as historic, insofar as behaviors, actions, and practices lie at the core of their concept of being. (shrink)

Levins and Lewontin have contributed significantly to our philosophical understanding of the structures, processes, and purposes of biological mathematical theorizing and modeling. Here I explore their separate and joint pleas to avoid making abstract and ideal scientific models ontologically independent by confusing or conflating our scientific models and the world. I differentiate two views of theorizing and modeling, orthodox and dialectical, in order to examine Levins and Lewontin’s, among others, advocacy of the latter view. I compare the positions of these (...) two views with respect to four points regarding ontological assumptions: (1) the origin of ontological assumptions, (2) the relation of such assumptions to the formal models of the same theory, (3) their use in integrating and negotiating different formal models of distinct theories, and (4) their employment in explanatory activity. Dialectical is here used in both its Hegelian–Marxist sense of opposition and tension between alternative positions and in its Platonic sense of dialogue between advocates of distinct theories. I investigate three case studies, from Levins and Lewontin as well as from a recent paper of mine, that show the relevance and power of the dialectical understanding of theorizing and modeling.

Serious actualism is the prima facie plausible thesis that things couldn’t have been related while being nothing. The thesis plays an important role in a number of arguments in metaphysics, e.g., in Plantinga’s argument for the claim that propositions do not ontologically depend on the things that they are about and in Williamson’s argument for the claim that he, Williamson, is necessarily something. Salmon has put forward that which is, arguably, the most pressing challenge to serious actualists. Salmon’s (...) objection is based on a scenario intended to elicit the judgment that merely possible entities may nonetheless be actually referred to, and so may actually have properties. It is shown that predicativism, the thesis that names are true of their bearers, provides the resources for replying to Salmon’s objection. In addition, an argument for serious actualism based on Stephanou, 219–250 2007) is offered. Finally, it is shown that once serious actualism is conjoined with some minimal assumptions, it implies property necessitism, the thesis that necessarily all properties are necessarily something, as well as a strong comprehension principle for higher-order modal logic according to which for every condition there necessarily is the property of being a thing satisfying that condition.

In this paper, I first present an overview of Asay’s _A Theory of Truthmaking_, highlighting what I take to be some of its most attractive features, especially his re-invigoration of the ontological understanding of truthmaking and his defence of ontology-first truthmaking over explanation-first truthmaking. Then, I articulate what I take to be a puzzling potential inconsistency: (a) he appeals to considerations to do with aboutness in criticising how well ontological views account for truth while (b) ruling out aboutness from (...) the right account of truthmaking. He argues, instead, that necessitation is both necessary and sufficient for truthmaking (§3.3). I suggest that adding aboutness to one’s account in the right way is not just compatible with but important for ontology-first truthmaking. I do all this to invite Asay to clarify his position on these matters. Overall, Asay’s worldview displays the fruitfulness of an ontologically serious approach to metaphysics that puts truthmaking centre-stage. (shrink)

Current controversies about knowledge integration reflect conflicting ideas of what it means to “take Indigenous knowledge seriously”. While there is increased interest in integrating Indigenous and Western scientific knowledge in various disciplines such as anthropology and ethnobiology, integration projects are often accused of recognizing Indigenous knowledge only insofar as it is useful for Western scientists. The aim of this article is to use tools from philosophy of science to develop a model of both successful integration and integration failures. On the (...) one hand, I argue that cross-cultural recognition of property clusters leads to an ontological overlap that makes knowledge integration often epistemically productive and socially useful. On the other hand, I argue that knowledge integration is limited by ontological divergence. Adequate models of Indigenous knowledge will therefore have to take integration failures seriously and I argue that integration efforts need to be complemented by a political notion of ontological self-determination.

Easy Ontology (EO), defended in several recent works by Amie Thomasson, and based on Carnap’s famous deflationism about metaphysics, is the view that many ontological questions, like ‘Are there numbers?’, are at bottom easy, at least when taken in their “internal” sense. Both Carnap and Thomasson take for granted that serious metaphysicians therefore cannot plausibly be interpreted as asking internal questions. Thus, they think they are committed to finding some alternative, special interpretation of metaphysicians’ utterances. I argue that (...) none of the alternative interpretations proposed in the literature are viable. More importantly, I argue that Carnap and Thomasson are wrong about this commitment. EO should instead be coupled with the view that metaphysicians ask internal questions, yet have the false belief that they can be answered only through metaphysical speculation. This is a significant modification of EO, in which the notion of an “external question” plays no role, and which results in a simpler and more plausible theory. (shrink)

This paper motivates taking seriously the possibility that brains are basically protean: that they make use of neural structures in inventive, on-the-fly improvisations to suit circumstance and context. Accordingly, we should not always expect cognition to divide into functionally stable neural parts and pieces. We begin by reviewing recent work in cognitive ontology that highlights the inadequacy of traditional neuroscientific approaches when it comes to divining the function and structure of cognition. Cathy J. Price and Karl J. Friston, and (...) Colin Klein identify the limitations of relying on forward and reverse inferences to cast light on the relation between cognitive functions and neural structures. There is reason to prefer Klein’s approach to that of Price and Friston’s. But Klein’s approach is neurocentric - it assumes that we ought to look solely at neural contexts to fix cognitive ontology. Using recent work on mindreading as a case study, we motivate adopting a radically different approach to cognitive ontology. Promoting the Protean Brain Hypothesis, we posit the possibility that we may need to look beyond the brain when deciding which functions are being performed in acts of cognition and in understanding how the brain contributes to such acts by adapting to circumstance.

In this article, I briefly explain the quantum measurement problem and the Everett interpretation, in a way that is faithful to modern physics and yet accessible to readers without any physics training. I then consider the metaphysical lessons for ontology from quantum mechanics under the Everett interpretation. My conclusions are largely negative: I argue that very little can be said in full generality about the ontology of quantum mechanics, because quantum mechanics, like abstract classical mechanics, is a framework (...) within which we can consider different physical theories which have very little in common at the level of ontology. Along the way I discuss, and criticise, several positive ontological proposals that have been made in the context of the Everett interpretation: ontologies based on the so-called "eigenstate-eigenvalue link", ontologies based on taking the "many-worlds" language seriously at the fundamental level, and ontologies that treat the wavefunction as a complex field on a high-dimensional space.

Helen Steward puts forward a radical critique of the foundations of contemporary philosophy of mind, arguing that it relies too heavily on insecure assumptions about the sorts of things there are in the mind--events, processes, and states. She offers a fresh investigation of these three categories, clarifying the distinctions between them, and argues that the category of state has been very widely and seriously misunderstood.

This paper examines the question of whether human rights are related to ontology. It examines perspectives on this question from human rights theories in the Western and African traditions of philosophy and defends the thesis that a good account of human rights requires an explicit ontology of the human, and that taking this seriously engenders divergent conclusions about what rights are. It then proceeds to claim that the African Charter on Human and Peoples’ Rights adds substantive features to (...) the International Bill of Human Rights, and that the Charter expresses Kwame Gyekye’s ontology of the human being.

In a series of papers, Eli Hirsch develops a deflationary account of certain ontological debates, specifically those regarding the composition and persistence of physical objects. He argues that these debates are merely verbal disputes between philosophers who fail to correctly express themselves in a common language. To establish the truth in plain English about these issues, Hirsch contends, we need only listen to the assertions of ordinary speakers and interpret them charitably. In this paper, I argue that Hirsch's conclusions rest (...) on a deficient understanding of the principle of charity. On a proper understanding of this principle, we can see that philosophical disagreement on these issues is not merely verbal. Further, it is no serious violation of charity to interpret ordinary assertions on these matters as false, for the beliefs they express can be explained as reasonable mistakes. Throughout I focus on the debate on composition; but my arguments should carry over to the debate on persistence. (shrink)

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I (...) discuss ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

1. IntroductionA popular view in metaphysics is that which propositions are true depends upon how the world is . In more evocative language, truth requires ground. This thought then gets used to do some serious work. As Sider has it, ‘[t]he point of … the principle that truth supervenes on being is to rule out dubious ontologies’. Here, I argue that ‘dubious’ ontologies are theoretically virtuous.

Feminist philosophy has recently become recognised as a self-standing philosophical sub-discipline. Still, metaphysics has remained largely dismissive of feminist insights. Here I make the case for the value of feminist insights in metaphysics: taking them seriously makes a difference to our ontological theory choice and feminist philosophy can provide helpful methodological tools to regiment ontological theories. My examination goes as follows. Contemporary ontology is not done via conceptual analysis, but via quasi-scientific means. This takes different ontological positions to be (...) competing hypotheses about reality’s fundamental structure that are then assessed with a loose battery of criteria for theory choice. Such criteria make up the constitutive values of ontology. These values are distinguished from contextual values of a practice: the political and moral values embedded in the social context of inquiry.. (shrink)

Researchers in areas such as artificial intelligence, formal and computational linguistics, biomedical informatics, conceptual modeling, knowledge engineering and information retrieval have come to realise that a solid foundation for their research calls for serious work in ontology, understood as a general theory of the types of entities and relations that make up their respective domains of inquiry. In all these areas, attention is now being focused on the content of information rather than on just the formats and languages (...) used to represent information. The clearest example of this development is provided by the many initiatives growing up around the project of the Semantic Web. And, as the need for integrating research in these different fields arises, so does the realisation that strong principles for building well-founded ontologies might provide significant advantages over ad hoc, case-based solutions. The tools of formal ontology address precisely these needs, but a real effort is required in order to apply such philosophical tools to the domain of information systems. Reciprocally, research in the information sciences raises specific ontological questions which call for further philosophical investigations. The purpose of FOIS is to provide a forum for genuine interdisciplinary exchange in the spirit of a unified effort towards solving the problems of ontology, with an eye to both theoretical issues and concrete applications. This book contains a wide range of areas, all of which are important to the development of formal ontologies. (shrink)

Contemporary political thought is deeply divided about the role of ontology in political thinking. Famously, political liberal John Rawls has argued that ontological claims are best to be avoided in political thought. In recent years, however, a number of theorists have claimed that ontology is essential to political philosophy. According to the contributors to this ‘ontological turn’, ontological investigations may foster the politicisation of hegemonic political theories and can highlight new possibilities for political life. This essay aims to (...) contribute to the debate about ontology in political philosophy by arguing that a compelling case for ontology can also be made in light of Rawls’ political liberalism itself, in particular, by taking seriously Rawls’ commitment to the politicisation of justice and the task of orientation of political philosophy. To make this case, the paper brings Rawls' perspective in conversation with the critical methodology and the ontology of agonism and reflections on parrhesia or frank truth-telling of Michel Foucault.

Actualism is the doctrine that the only things there are, that have being in any sense, are the things that actually exist. In particular, actualism eschews possibilism, the doctrine that there are merely possible objects. It is widely held that one cannot both be an actualist and at the same time take possible world semantics seriously — that is, take it as the basis for a genuine theory of truth for modal languages, or look to it for insight into the (...) modal structure of reality. For possible world semantics, it is supposed, commits one to possibilism. In this paper I take issue with this view. To the contrary, I argue that one can take possible world semantics seriously without any commitment to possible worlds or possibilism and hence remain in full compliance with actualist scruples. Moreover, one can do so without without invoking either "ersatz" worlds or haecceities. (shrink)

It is persons who are ontologically committed. But a person is not ontologically committed by virtue of his character, his height, his social standing or whatever, but by virtue of the sentences he assents to. Hence we should look to sentences for a criterion of ontological commitment. This is precisely what is done by advocates of what I will call the Referential theory. In this paper I argue that the Referential theory faces serious objections related to the role paraphrase (...) must play in it. I then present a modified Referential theory and go on to discuss certain implications of the modified theory. More precisely, the paper divides up as follows. In §1 I present the Referential theory. In §2 I argue that it is in trouble over paraphrase. In §3 I consider a general objection to the arguments of §2. In §4 I present the modified theory. In §5 I consider the implications of the modified theory for polemic over what there is and for the existence of properties or universals. (shrink)

We explain that most of the explanations that traditionally have been used to conceptually and ontologically differentiate aesthetic experience from any other are not compatible with a naturalistic framework, since they are based on transcendental idealistic metaphysics, reductions, and on the assumption that the aesthetic is an a priori special ontology in the object and the mind. However, contemporary works that propose as an alternative to apply directly evidence and theory from the science of emotions to the problem of (...) aesthetics introduce Aesthetic Science into a new set of problematic assumptions. We argue that conceptually equating or ontologically reducing the aesthetic to the theory of rewards cannot provide a clear alternative for any Aesthetic Science to naturalize the aesthetic experience as a heterogeneous class of events that are not already explained by affective science. This practice introduces a serious danger of making the term “aesthetic” and the respective scientific field pretty weak or completely redundant and unnecessary. (shrink)

Criticism of post-modernizm and post-colonializm caused to question the mission of anthropology in terms of understanding different societies. Materialist, secular and anthropocentric anthropological approaches based on enlightenment and modern assumptions have faced criticism by many disciplines from philosophy and critical theory to science and quantum theory. Anthropology of religion which is a branch of cultural anthropology is also effected by changes within the broader field of anthropology. The aim of this project is to shed light on the potential of the (...) critical approach, which emerged in anthropology of religion recently and underlined the ontology, to understand religious experiences and practices of different societies. This approach is called ontological turn. In this article, first I point out the historical process in anthropology which led to the turn to ontology. Social structuralism and representationalism which played an important role for the formation of anthropology impacted significantly the ways in which anthropology understands nature and human being. According to these assumptions commonly used in anthropology, while human beings try to understand universal and static natural law principles, they create representations about nature. But, for there is only one nature, there must be only one true representation. This attempt to understand nature through representations created the base for the concepts of belief, knowledge, and mind of Edward Tylor who was the pioneer of cultural anthropology. While the mind refers to rational capacity of human being, belief is an area of irrational representations that human beings pragmatically need. Religious assumptions and practices are listed under incorrect representations. The concept of belief has been frequently used after Tylor as well to understand societies which are located outside of modernity. What ontological turn aims with criticism of conceptual framework is to prevent the domination of Western based reality. Therefore, one of the most emphasized arguments is the multiplicity of reality. This approach of ontological turn is called as taking everything serious. New definitions which are made in a way including the experiences of ethnographic objects mean taking them serious. Acceptance of the concepts by anthropologist in the ethnographic field means acceptance of difference in reality. The act of definition and conceptualizing is the act of creating different realities. In many ethnographic researches, ethnographers choses their concepts before entering to the field. This means that trying to fit differences within existing concepts and confirming the existing thoughts from different perspectives. Understanding ethnographic materials with its own terms or analyzing, explaining or interpreting ethnographic phenomenon by eliminating presumptions was always a concern for anthropology. These questions are asked so commonly that they can be seen as banal questions. The difference of ontological turn is not to ask these questions, but to ask ontological questions as an epistemological approach. The base of this ontological approach is the thought that what forms anthropologists’ perspective are not social or cultural but ontological assumptions. Thus, the question to be asked is how anthropologists’ assumptions about what the world is can be eliminated. To sum up, the idea of taking everything serious in ontological turn aims to eliminate the hierarchy between the subject and object of ethnography. Instead of seeing ethnography as an object of anthropology through modern categories, ontological turn suggests seeing ethnography as a real source to create new concepts and analytical tools.

The number of positions identified with structural realism in philosophical debates about scientific knowledge has grown significantly in the past decade, particularly with respect to the metaphysical or ‘ontic’ approach (OSR). In recent years, several advocates of OSR have proposed a novel understanding of it in order to side-step a serious challenge faced by its original formulation, eliminative OSR. I examine the conceptual basis of the new, noneliminative view, and conclude that it too faces a serious challenge, resulting (...) in a dilemma for ontic structuralists regarding the ontological status of objects and properties, and the relative “ontological priority” of these entities with respect to the relations in which they stand.

In this challenging study in metaphilosophy, Douglas Browning makes a case for viewing ontology as a legitimate and viable philosophical pursuit. Beginning with a sustained analysis of the process of attempting to construct a system that is true of the whole of reality, he proceeds to focus upon the issues of the need for and availability of controls upon speculative construction. He concludes by arguing for the importance of one such speculative control, namely, an appeal to the structural traits (...) of the practical stratum of our lives. In the course of his discussion Browning also develops original theories of stances, appearing, and the general structure of theoretical investigation. The book is divided into two parts. The first is devoted to consideration of the overall shape of the ontological enterprise as a process of moving from the pole of initial ontological questioning toward the pole of the provision of an acceptable system. While each of these two poles is discussed in turn in some detail, it is the mediating process of inquiry and construction, of "doing" ontology, to which Browning devotes most of his attention. His examination of this process reveals serious difficulties, one of which, he argues, provides the most serious threat to the acceptability of ontology as a viable project. This difficulty centers on the issue of discovering a manner of access to reality that is sufficiently favored over the others to provide a cue for the constructive imagination. In the second part, Browning proposes a way of overcoming this difficulty. After presenting a general argument for the primacy of the practical stance in our lives, he makes and defends a number of proposals regarding the general structure of the arena of acting that this stance discloses. The book ends by showing the extent to which an appeal to this structure would ensure, not the success, but the viability of ontological investigation. (shrink)

I argue that Amie Thomasson’s recent theory of the methodology to be applied to find the truth-conditions for claims of existence faces serious objections. Her account is based on Devitt and Sterelny’s solution to the qua problem for theories of reference fixing; however, such a solution cannot be also applied to analyze existential claims.

In a recent article, ‘Tensed Time and Our Differential Experience of the Past and Future,’ William Lane Craig attempts to resuscitate A. N. Prior's ‘Thank Goodness’ argument against the B-theory by combining it with Plantinga's views about basic beliefs. In essence Craig's view is that since there is a universal experience and belief in the objectivity of tense and the reality of becoming, ‘this belief constitutes an intrinsic defeater-defeater which overwhelms the objections brought against it.’ An intrinsic defeater-defeater is a (...) belief that enjoys such warrant for us that it simply overwhelms the defeaters brought against it without specifically rebutting or undercutting them. Thus, Craig claims that an effete philosophical argument like McTaggart's paradox is nothing more than ‘an engaging and recalcitrant brain teaser whose conclusion nobody really takes seriously.’ It is difficult to reconcile this statement with Craig's own writings elsewhere. For Craig has vigorously argued in at least two other articles that 'hybrid A-B theorists like McCall, Schlesinger, and Smith [who give ontological status to both A-properties and B-relations] are in deep trouble’ since they are all effectively refuted by McTaggart's Paradox. It is not Craig's inconsistency regarding the significance of McTaggart conundrum that I want to draw attention to, however. Rather I wish to raise a different issue. (shrink)

My focus here will be Rudolf Carnap’s views on ontology, as these are presented in the seminal “Empiricism, Semantics and Ontology” (1950). I will first describe how I think Carnap’s distinction between external and internal questions is best understood. Then I will turn to broader issues regarding Carnap’s views on ontology. With certain reservations, I will ascribe to Carnap an ontological pluralist position roughly similar to the positions of Eli Hirsch and the later Hilary Putnam. Then I (...) turn to some interrelated arguments against the pluralist view. The arguments are not demonstrative. Some possible escape routes for the pluralist are outlined. But I think the arguments constitute a formidable challenge. There should be serious doubt as to whether the pluralist view, as it emerges after discussion of these arguments, will be worth defending. Moreover, there is an alternative ontological view which equally well subserves the motivations underlying ontological pluralism. (shrink)

This article is a clarification and development of my interpretation of Sartre’s theory of bad faith in response to Ronald Santoni’s sophisticated critique, published in this issue. It begins by clarifying Sartre’s conception of a project and explaining his claim that one project is fundamental, thereby elucidating the idea that bad faith is a fundamental project. This forms the groundwork of my responses to Santoni’s critique of my interpretation, which comprises four arguments: Sartre does not consider us to be ontologically (...) and congenitally disposed to bad faith; Santoni is right that social pressure cannot explain the prevalence of bad faith, but this is a problem with Sartre’s theory rather than a problem for my interpretation of it; Sartre’s conception of seriousness is merely an optional strategy of bad faith; and Sartre is right to deny that bad faith is an inherently cynical project.

Recently, there has been a revival in taking empirical magnitudes seriously. Weights, heights, velocities and the like have been accepted as abstract entities in their own right rather than just equivalence classes of objects. The aim of my paper is to show that this revival should include value magnitudes. If we posit such magnitudes, important value comparisons can be easily explained; it becomes easier to satisfy the axioms for measurement of value; goodness, badness, and neutrality can be given univocal definitions; (...) value aggregation can be given a non-mathematical understanding which allows for Moorean organic unities. Of course, this does not come for free. One has to accept a rich ontology of abstract value magnitudes, but, to quote David Lewis, ‘The price is right; the benefits in theoretical unity and economy are well worth the entities.’. (shrink)

The general topic of my philosophical dissertation is phenomenological ontology of breathing. I do not investigate the phenomenon of breathing as a natural scientific problem, but as a philosophical question. Within our tradition, breathing has been normally understood as a mechanistic-materialistic physiological life-sustaining process of gas exchange and cellular respiration which does not really seem to have any essential connection to human being’s spiritual, mental or philosophical capacities. On the contrary to this natural scientific view, I argue that breathing (...) can be understood as a philosophical question that has phenomenological, experiential, ontological, spiritual, bodily, mental, poetic, elemental, ethical, voluntary and mystical dimensions. My investigation conceptualizes breathing in the first place as a question of phenomenological ontology. Maurice Merleau-Ponty’s phenomenologico-ontological method of interrogation of the lived body’s experiential openness to the world and Being provides the most fundamental point of departure in this dissertation. Merleau-Ponty emphasized in his investigations the lived body’s perceptual openness to the world and Being. He argued famously for the primacy of perception. His thesis of the primacy of perception means that perception as the perceptual openness to the world and Being is the foundation which is always presupposed by all the other levels of our existence and being-in-the-world. In this dissertation, I challenge this idea of the primacy of perception with Merleau-Ponty’s own remarks about breathing. I argue that in his own remarks about breathing, he implicitly points toward a level which is even more fundamental than the primacy of perception. In this dissertation, this level of our being-in-the-world I call the primacy of breathing. Breathing as the lived body’s respiratory openness to the world and Being is now understood as the foundation which is always presupposed by all the other dimensions of our being-in-the-world. These dimensions are, for example, our theoretical, practical, social and perceptual ways of relating with the world. If the idea of the primacy of breathing is taken seriously, it means that all the questions of philosophy could be rethought, reexamined and re-experienced within the fundamental atmosphere of respiratory openness to the world and Being. In this dissertation, I initially try to rethink philosophy as a new philosophy of breathing. This new philosophy of breathing would be phenomenological ontology of breathing. The bases of this new phenomenological ontology of breathing are Merleau-Ponty’s remarks about breathing. My task is to explicate and interpret them with the help of Merleau- Ponty’s own phenomenological ontology. In my task of beginning philosophy anew as philosophy of breathing or as respiratory philosophy, I will also use the ideas of Martin Heidegger, Gaston Bachelard, Paul Claudel, Luce Irigaray, Edmund Husserl and David Kleinberg-Levin. My dissertation is divided into two main sections. In Section One, I construct within the framework of phenomenological ontology a new notion of breathing as the primacy of breathing. In Section Two, I develop a phenomenological method that I call the method of ontologico-respiratory reduction. This method will lead us back to the primacy of breathing. (shrink)

Philosophers of science have long been concerned with the question of what a given scientific theory tells us about the contents of the world, but relatively little attention has been paid to how we set out to build theories and to the relevance of pre-theoretical methodology on a theory’s interpretation. In the traditional view, the form and content of a mature theory can be separated from any tentative ontological assumptions that went into its development. For this reason, the target of (...) interpretation is taken to be the mature theory and nothing more. On this view, positions on ontology emerge only once a theory is to hand, not as part of the process of theory building. Serious attention to theory creation suggests this is too simple. In particular, data collection and experimentation are influenced both by theory and by assumptions about the entities thought to be the target of study. Initial reasoning about possible ontologies has an influence on the choice of theoretical variables as well as on the judgments of the methodology appropriate to investigate them. (shrink)

The paper argues that the formulation of quantum mechanics proposed by Ghirardi, Rimini and Weber (GRW) is a serious candidate for being a fundamental physical theory and explores its ontological commitments from this perspective. In particular, we propose to conceive of spatial superpositions of non-massless microsystems as dispositions or powers, more precisely propensities, to generate spontaneous localizations. We set out five reasons for this view, namely that (1) it provides for a clear sense in which quantum systems in entangled (...) states possess properties even in the absence of definite values; (2) it vindicates objective, single-case probabilities; (3) it yields a clear transition from quantum to classical properties; (4) it enables to draw a clear distinction between purely mathematical and physical structures, and (5) it grounds the arrow of time in the time-irreversible manifestation of the propensities to localize.

"Ontology and the Foundations of Mathematics" consists of three papers concerned with ontological issues in the foundations of mathematics. Chapter 1, "Numbers and Persons," confronts the problem of the inscrutability of numerical reference and argues that, even if inscrutable, the reference of the numerals, as we ordinarily use them, is determined much more precisely than up to isomorphism. We argue that the truth conditions of a variety of numerical modal and counterfactual sentences place serious constraints on the sorts (...) of items to which numerals, as we ordinarily use them, can be taken to refer: Numerals cannot be taken to refer to objects that exist contingently such as people, mountains, or rivers, but rather must be taken to refer to objects that exist necessarily such as abstracta. ;Chapter 2, "Modern Set Theory and Replacement," takes up a challenge to explain the reasons one should accept the axiom of replacement of Zermelo-Fraenkel set theory, when its applications within ordinary mathematics and the rest of science are often described as rare and recondite. We argue that this is not a question one should be interested in; replacement is required to ensure that the element-set relation is well-founded as well as to ensure that the cumulation of sets described by set theory reaches and proceeds beyond the level o of the cumulative hierarchy. A more interesting question is whether we should accept instances of replacement on uncountable sets, for these are indeed rarely used outside higher set theory. We argue that the best case for replacement comes not from direct, intuitive considerations, but from the role replacement plays in the formulation of transfinite recursion and the theory of ordinals, and from the fact that it permits us to express and assert the content of the modern cumulative view of the set-theoretic universe as arrayed in a cumulative hierarchy of levels. ;Chapter 3, "A No-Class Theory of Classes," makes use of the apparatus of plural quantification to construe talk of classes as plural talk about sets, and thus provide an interpretation of both one- and two-sorted versions of first-order Morse-Kelley set theory, an impredicative theory of classes. We argue that the plural interpretation of impredicative theories of classes has a number of advantages over more traditional interpretations of the language of classes as involving singular reference to gigantic set-like entities, only too encompassing to be sets, the most important of these being perhaps that it makes the machinery of classes available for the formalization of much recent and very interesting work in set theory without threatening the universality of the theory as the most comprehensive theory of collections, when these are understood as objects.
