'Structural realism' is a buzzword in the scientific realism debate. Various positions with diverse motivations fall under this label. A much advertised distinction is between epistemic and ontological forms of structuralism. This paper scrutinizes the alleged dichotomy between these two 'alternatives', and criticises the considerations that have been taken to motivate the ontic variety over the epistemic. I will argue that ontological structural realism is not called for within the traditional realism debate.

In recent years, a hierarchical view of reality has become extremely influential. In order to understand the world as a whole, on this view, we need to understand the nature of the fundamental constituents of the world. We also need to understand the relations that build the world up from these fundamental constituents. Building pluralism is the view that there are at least two equally fundamental relations that together build the world. It has been widely, though tacitly, assumed in a (...) variety of important metaphysical debates. However, my primary aim in this paper is to argue that this has been a mistake. I will show that serious problems concerning the relationship between building and fundamentality afflict pluralism and are likely fatal to it. I claim that, for better or worse, our best hope is building singularism, the view that there is a single most fundamental building relation. I conclude by examining the advantage that singularist accounts enjoy over their pluralist rivals. (shrink)

Recent discussions of ontology have shown an interest in the relation between logic, language and ontology. Quine, for example, has shown how sentences translated into canonical form determine ontological commitment in terms of the values over which bound variables range, while Strawson has maintained that conditions inherent to language determine a system of ontological concepts. But in these discussions the role linguistics might have in the construction of ontological schemes is seldom seriously considered. Except for Benjamin Lee (...) Whorf’s examination through the use of descriptive linguistic techniques of the relation between ontological schemes and the structure of languages, little has been done to apply the results of linguistic research to questions of ontology. In the past this could be attributed to the absence in structural linguistics of significant generalizations about language above the morphophonemic level. This situation has altered with the development of transformational linguistic theory. That theory contains an extensive set of generalizations about the form and content of any natural language.

This thesis provides a comparative analysis of the different ways Hegel and Sartre understand that consciousness can be alienated. Because understanding the various ways Hegel and Sartre hold that consciousness can be alienated is not possible without first understanding what each thinker understands by consciousness, I first identify and outline the different ways Hegel and Sartre conceptualise consciousness’s ontological structure before identifying the various ways each thinker understands that consciousness can be alienated. The general argument developed shows that (...) while Hegel and Sartre agree that alienation is a constitutive aspect of consciousness’s existence and are, therefore, allies in the battle against it, Sartre’s analysis of consciousness’s ontological structure is unable to provide the same depth of analysis as Hegel’s. Put differently, I believe it is Hegel’s analysis of consciousness’s ontological structure that provides an analysis of alienation that is more nuanced, subtle, complex, and multi-dimensional than the account Sartre’s provides. To support my argument, I first explore Sartre’s understanding of consciousness’s ontological structure. This discloses that, because Sartre defines consciousness as ontologically nothing, he holds that consciousness is defined in strict ontological opposition to objectivity. Consciousness’s ontological nothingness leads Sartre to hold that consciousness is free to choose its mode of being. This leads me to identify what Sartre holds to be constitutive of authentic and inauthentic modes of being. But while Sartre distinguishes between the ontological structure of consciousness and its experiences, I argue that Hegel: 1) does not introduce a distinction between consciousness’s ontological structure and its mode of being, but holds that consciousness’s self-understanding and ontological structure develop through its experiences; and 2) holds that consciousness is not ontologically opposed to objectivity, but is a spiritual synthesis of subjectivity and objectivity. I show that because Hegel holds that consciousness’s intentional object is an aspect of its ontological structure, rather than something simply opposed to itself, and because he recognises that consciousness must learn what it is ontologically by experiencing numerous different relations with its object, he is able to show that while the subject/object binary opposition of Sartre’s analysis of consciousness’s ontological structure describes one potential ontological relation consciousness can have to its object, it is not the only one. Indeed, Hegel’s analysis of consciousness’s ontological structure insists that consciousness will only truly understand its ontological structure if it learns to not think of itself in terms of the subject/object dichotomy and, instead, realises that it is a spiritual synthesis of subjectivity and objectivity. To show how this fundamental difference manifests itself throughout their thought, I identify and compare what each thinker’s understanding of consciousness’s ontological structure means in terms of consciousness’s relation to the world, alienation, authenticity, ethics, self-transformation, and social relations.

In 1982, Wolniewicz proposed a formal ontology of situations based on the lattice of elementary situations (cf. [7, 8]). In [3], I constructed some types of formal structure Porphyrian Tree Structures (PTS), Concepts Structures (CS) and the Structures of Individuals (U) that formally represent ontologically fundamental categories: species and genera (PTS), concepts (CS) and individual beings (U) (cf. [3, 4]). From an ontological perspective, situations and concepts belong to different categories. But, unexpectedly, as I shall show, some variants (...) of CS and Wolniewicz’s lattice are similar. The main theorem states that a subset of a modified concepts structure (called CS+) based on CS fulfils the axioms of Wolniewicz’ lattice. Finally, I shall draw some philosophical conclusions and state some formal facts. (shrink)

In this paper, I pay tribute to Jonathan Webber, one of the most dependable interpreters among recent Sartre scholars. I do so by challenging both him and Sartre on an issue that has long frustrated my work on Sartre. In short, Sartre contends that the For-itself’s desire to be Being-in-itself-for-itself is in bad faith. This raises two issues: Is this desire to be ens causa sui part of the ontological structure of the For-itself? If so, is bad faith (...) an essential part of the human being? I contend that the desire to be the In-itself-for-itself is, on Sartre’s premises, part of the ontological structure of an existing human being. As our original flight from freedom and “fundamental project,” this constitutes bad faith’s “coming into the world,” and remains part of Being-for-itself’s “natural” disposition to bad faith.

In Sein und Zeit , Heidegger claims that (1) das Man is an 'existential' i.e. a necessary feature of Dasein's Being; and (2) Dasein need not always exist in the mode of the Man -self, but can also be eigentlich , which I translate as 'self-owningly'. These apparently contradictory statements have prompted a debate between Hubert Dreyfus, who recommends abandoning (2), and Frederick Olafson, who favors jettisoning (1). I offer an interpretation of the structure of Dasein's Being compatible with (...) both (1) and (2), thus resolving the Dreyfus-Olafson debate. Central to this resolution is the distinction between das Man and the Man -self. Das Man is one of three existential 'horizons', or fields of possibilities; the other two horizons are the world and death. At any time, Dasein encounters entities in one of two basic modes: either by 'expressly seizing' possibilities of the horizon, or by occluding these possibilities. These modes are 'existenti ell ', i.e. features of Dasein's Being that are possible, but not essential. Self-ownership and the Man -self are the two basic existentiell modes of being oneself, i.e. projecting everyday possibilities of oneself appropriated from the horizon of das Man . What differentiates these two modes is the stance one takes to the possibility of death, the existential horizon of being oneself. (shrink)

Social groups—like teams, committees, gender groups, and racial groups—play a central role in our lives and in philosophical inquiry. Here I develop and motivate a structuralist ontology of social groups centered on social structures (i.e., networks of relations that are constitutively dependent on social factors). The view delivers a picture that encompasses a diverse range of social groups, while maintaining important metaphysical and normative distinctions between groups of different kinds. It also meets the constraint that not every arbitrary collection of (...) people is a social group. In addition, the framework provides resources for developing a broader structuralist view in social ontology. (shrink)

Combinations of molecules, of biological individuals, or of chemical processes can produce effects that are not simply attributable to the constituents. Such non-redundant causality warrants recognition of those coherences as ontologically significant whenever that efficacy is relevant. With respect to such interaction, the effective coherence is more real than are the components. This ontological view is a variety of structural realism and is also a kind of process philosophy. The designation ‘process structural realism’ (PSR) seems appropriate.

In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the best confirmed theories (...) in science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. (shrink)

Words form a fundamental basis for our understanding of linguistic practice. However, the precise ontology of words has eluded many philosophers and linguists. A persistent difficulty for most accounts of words is the type-token distinction [Bromberger, S. 1989. “Types and Tokens in Linguistics.” In Reflections on Chomsky, edited by A. George, 58–90. Basil Blackwell; Kaplan, D. 1990. “Words.” Aristotelian Society Supplementary Volume LXIV: 93–119]. In this paper, I present a novel account of words which differs from the atomistic and platonistic (...) conceptions of previous accounts which I argue fall prey to this problem. Specifically, I proffer a structuralist account of linguistic items, along the lines of structuralism in the philosophy of mathematics [Shapiro, S. 1997. Philosophy of Mathematics: Structure and Ontology. Oxford University Press], in which words are defined in part as positions in larger linguistic structures. I then follow Szabò [1999. “Expressions and Their Representations.” The Philosophical Quarterly 49 (195): 145–163] and Parsons [1990. “The Structuralist View of Mathematical Objects.” Synthese 84: 303–346] in further defining words as quasi-concrete objects according to a representation relation. This view aims for general correspondence with contemporary generative linguistic approaches to the study of language. (shrink)

This essay explores the possibility of constructing a structural realist interpretation of spacetime theories that can resolve the ontological debate between substantivalists and relationists. Drawing on various structuralist approaches in the philosophy of mathematics, as well as on the theoretical complexities of general relativity, our investigation will reveal that a structuralist approach can be beneficial to the spacetime theorist as a means of deflating some of the ontological disputes regarding similarly structured spacetimes.

The agent-structure problem is a much discussed issue in the field of international relations. In his comprehensive analysis of this problem, Colin Wight deconstructs the accounts of structure and agency embedded within differing IR theories and, on the basis of this analysis, explores the implications of ontology - the metaphysical study of existence and reality. Wight argues that there are many gaps in IR theory that can only be understood by focusing on the ontological differences that construct (...) the theoretical landscape. By integrating the treatment of the agent-structure problem in IR theory with that in social theory, Wight makes a positive contribution to the problem as an issue of concern to the wider human sciences. At the most fundamental level politics is concerned with competing visions of how the world is and how it should be, thus politics is ontology. (shrink)

Whitehead’s cosmology centers on the self-creation of actual occasions that perish as they come to be, but somehow do combine to constitute societies that are persistent agents and/or patients. “Instance Ontology” developed by D.W. Mertz concerns unification of relata into facts of relatedness by specific intensions. These two conceptual systems are similar in that they both avoid the substance-property distinction: they differ in their understanding of how basic units combine to constitute complex unities. “Process Structural Realism” (PSR) draws from both (...) of these approaches in developing an account of how combinations of processes may produce ontologically significant coherences. When a group of processes achieves such closure that a set of states recurs continually, the effects of that coherence differ from what would occur in the absence of that closure. Such altered effectiveness is an attribute of the system as a whole, and would have consequences. This indicates that the network of processes, as a unit, has ontological significance. The closed network of processes, together with the conditions that prevail, constitute the form of definiteness of the coherence. That form continues to obtain as long as the coherence persists. Constituents contribute to, rather than share, that characteristic. Aspects of some recent research in systems biology, microeconomics, and social psychology illustrate the application of PSR.

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

Through a comparative case analysis regarding the Chinese language, it is discussed how the structure and functions of a natural language would bear upon the ways in which some philosophical problems are posed and some ontological insights shaped. Disagreeing with Chad Hansen's mass-noun hypothesis, a collective-noun hypothesis is argued for: (1) the denotational semantics and relevant grammatical features of Chinese nouns are like those of collective nouns; (2) their implicit ontology is a mereological ontology of collection-of-individuals with both (...) part-whole and member-class structure; and (3) encouraged and shaped by the folk semantics of Chinese nouns, classical Chinese theorists of language take this kind of mereological nominalism for granted.

Between 1934 and 1937 Maurice Blondel, the French Roman Catholic philosopher best known for his 1893 work, Action, published a trilogy of writings. Out of these writings came a theological ontology of tremendous force, creativity, and coherence. The purpose of the present dissertation is to reassess the viability of Blondel's ontology for contemporary theology. The retrieval begins with John Milbank's 1990 investigation of Blondel's early philosophy. While Milbank focuses on the strengths of Blondel, he also highlights some critical weaknesses. The (...) dissertation argues that Blondel later came to recognize and correct these weaknesses in his trilogy. ;La pensee, the first volume of the trilogy, discusses the nature and development of thought. Recognizing the ontological structure of thought leads Blondel to present his doctrine of the transnatural elan for assimilation to God. The transnatural desire for God is compared with Henri de Lubac's notion of naturae desiderium and then applied to the modern problem of the relationship between nature and supernature. ;The second installment of the trilogy, L'etre et les etres , explores the mysterious relation of Being and beings. Blondel situates the discussion within the language of creation, identifying Being as Creator and beings as creatures. The analogy of creation allows him to forge the proper relationship between Being and beings. After Blondel's death, two different schools of thought emerged on the mystery of being: Karl Rahner's Thomism and Jean-Luc Marion's new phenomenology. Each school is reviewed and critiqued from a Blondelian perspective. ;The trilogy concludes with a long-awaited revision of L'action . It begins by distinguishing the idea of action from action itself and establishing the ontological difference of action. Action is presented ontologically as enacted power, which is investigated in its individual, social, and metaphysical forms. Individual action is identified as making, practicing, and contemplating. Social action is studied next, with the conclusion that the social being of enacted power is determined by either a philosophy of peace or violence. Finally, divine action is evaluated with regards to the language of causality and absolute power. Blondel proposes instead to describe God's activity in terms of pure action. (shrink)

The aim of this paper is to offer two novel solutions to two perennial problems of categorial ontology, namely, the problem of the categorial structure: how are the categories related to one another? And the problem of categorial completeness: how is the completeness of a proposed list of categories justified? First, I argue that a system of categories should have a structure such that there is a most basic category that is a bearer of all other categories and (...) that has what I shall call “combinatorial conditions”. To do so, I compare this approach to categorial structure with the approaches given by substantialist, mereological, factualist, and geo ontologies. Second, I argue that the problem of categorial completeness is only a problem for certain ontologies. In this connection, I explore views on categorial completeness proposed by substantialists and geo-ontologists. Lastly, I conclude that factualism does a better job of accounting for categorial structure and categorial completeness than other categorial ontologies. (shrink)

The phenomenon of rigid designation - in particular, de jure rigidity - is typically treated metaphysically. The picture is: reference is gained in a way that puts no constraints on what an object in other worlds, or counterfactual situations must be like, in order to be the referent of that term, other than 'being this thing'. This allows 'pure metaphysical' investigation into, and discovery of 'the nature' of the referent. It is argued that this presupposes a 'privileged' ontology, of a (...) sort that is far from obvious. An alternative picture of rigidity is sketched, terms have associated criteria of identity and criteria of application for counterfactual situations. A term is rigid when these coincide. Aside from being a better account of rigidity, it also undermines the picture of rigid terms allowing us to 'metaphysically' investigate the nature of the referent: matters of identity and essence for the referent are settled by these semantic constraints (though it can be done in a way that allows are a posteriori necessities).

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.

This chapter introduces a structural account of representation through partial structures and examines its ontological commitments. It is pointed out that structural approaches to scientific representation emphasize the crucial role played by structures in representing salient features of the world. It is common to present and, in some cases, even to reify such structures as abstract entities, in particular as set-theoretic constructs. Against this view, it is argued that no such reification is called for and that several strategies can (...) be articulated to avoid commitment to set-theoretic structures in the defense of structural representation. In the end, one can favor the latter without being platonist about the former. (shrink)

W.V. Quine, a champion of philosophical naturalism and pioneer of mathematical logic, was one of the most important philosophers of the 20th century.

This paper discusses attributively limited concrete objects such as disturbances (holes, folds, scratches etc), tropes, and attitudinal objects, which lack the sort of spatial location or part structures expected of them as concrete objects. The paper proposes an account in terms of (quasi-Fregean) abstraction, which has so far been applied only to abstract objects.

Could space consist entirely of extended regions, without any regions shaped like points, lines, or surfaces? Peter Forrest and Frank Arntzenius have independently raised a paradox of size for space like this, drawing on a construction of Cantor’s. I present a new version of this argument and explore possible lines of response.

Do numbers, sets, and so forth, exist? What do mathematical statements mean? Are they literally true or false, or do they lack truth values altogether? Addressing questions that have attracted lively debate in recent years, Stewart Shapiro contends that standard realist and antirealist accounts of mathematics are both problematic. As Benacerraf first noted, we are confronted with the following powerful dilemma. The desired continuity between mathematical and, say, scientific language suggests realism, but realism in this context suggests seemingly intractable epistemic (...) problems. As a way out of this dilemma, Shapiro articulates a structuralist approach. On this view, the subject matter of arithmetic, for example, is not a fixed domain of numbers independent of each other, but rather is the natural number structure, the pattern common to any system of objects that has an initial object and successor relation satisfying the induction principle. Using this framework, realism in mathematics can be preserved without troublesome epistemic consequences. Shapiro concludes by showing how a structuralist approach can be applied to wider philosophical questions such as the nature of an "object" and the Quinean nature of ontological commitment. Clear, compelling, and tautly argued, Shapiro's work, noteworthy both in its attempt to develop a full-length structuralist approach to mathematics and to trace its emergence in the history of mathematics, will be of deep interest to both philosophers and mathematicians.

ABSTRACTLadyman and Ross’s account of the metaphysical component of ontic structural realism was associated with a unificationist view of the connection between fundamental physics and special sciences. The aim of the present article is to assess the sense of unification that is at issue in Ladyman and Ross’s definition of metaphysics. Given the ontic core of Ladyman and Ross’s version of structural realism, it should be assumed that the unifying endeavour is worthwhile only if the connective links that underpin unification (...) are metaphysically significant. Ladyman and Ross employed information-theoretic notions, e.g. ‘projectibility’, to account for the significance of real patterns, which underpin unification. I build upon McAllister’s engagements with the same topic, to argue that these notions fail to accomplish this objective. (shrink)

Realities are structured categorially, and comprehension of our internal and external conditions do not appear to be global or unitary. Rather, both human and non human animals function within their worlds and understand these by categorizing their experiences. Drawing upon many areas of life, the authors consider the ontological, mereological and multi-faceted structure of experience to explore how an understanding of categories can further knowledge.

This article proposes a guideline to develop an ontology of software. The first section gives a brief introduction to the importance of such ontology as a possible conceptual grounding for the philosophy of software, philosophy of computing and philosophy of information.

The third section deploys the basic guidelines with the expositions of the two dimensions of software: the (...) serial dimension and the structural dimension. The first dimension consists of three series, while the second in the exposition of the structure of any program. The fourth and last section will deal with a better understanding of what we can call the digital universe. (shrink)

The Protein Ontology (PRO; http://proconsortium.org) formally defines protein entities and explicitly represents their major forms and interrelations. Protein entities represented in PRO corresponding to single amino acid chains are categorized by level of specificity into family, gene, sequence and modification metaclasses, and there is a separate metaclass for protein complexes. All metaclasses also have organism-specific derivatives. PRO complements established sequence databases such as UniProtKB, and interoperates with other biomedical and biological ontologies such as the Gene Ontology (GO). PRO relates to (...) UniProtKB in that PRO’s organism-specific classes of proteins encoded by a specific gene correspond to entities documented in UniProtKB entries. PRO relates to the GO in that PRO’s representations of organism-specific protein complexes are subclasses of the organism-agnostic protein complex terms in the GO Cellular Component Ontology. The past few years have seen growth and changes to the PRO, as well as new points of access to the data and new applications of PRO in immunology and proteomics. Here we describe some of these developments. (shrink)

Moving beyond both realist and anti-realist accounts of mathematics, Shapiro articulates a "structuralist" approach, arguing that the subject matter of a mathematical theory is not a fixed domain of numbers that exist independent of each other, but rather is the natural structure, the pattern common to any system of objects that has an initial object and successor relation satisfying the induction principle.

We use the primitive ontology framework of Allori et al. to analyze the quantum information-theoretic interpretation of Bub and Pitowsky. There are interesting parallels between the two approaches, which differentiate them both from the more standard realist interpretations of quantum theory. Where they differ, however, is in terms of their commitments to an underlying ontology on which the manifest image of the world supervenes. Employing the primitive ontology framework in this way makes perspicuous the differences between the quantum information-theoretic interpretation, (...) and the various realist interpretations of quantum theory. It also allows us to identify a sense in which the commitments of quantum information-theoretic interpretation are underspecified. Several possible ways of completing the interpretation are presented, and it is suggested that the most likely strategy would leave the information-theoretic interpretation such that it would fail to qualify as a theory, according to the primitive ontology approach.
