Since 1989, widely circulating statistics on gay teen suicide in the United States have acted as catalysts for institutional reforms, scientific research, and the creation of an identity category “gay youth.” While one figure has been replicated scientifically, these numbers originated not from a scientific research study but as risk estimates developed by a social worker and published in a government document. Many people within the public took up these original numbers, attributing their author the status of scientific researcher. In (...) effect, the numbers became “black boxed,” often traveling without citation. Drawing on Ian Hacking’s “dynamic nominalist” perspective, this article utilizes interviews with the author of these statistics and other key claimants, along with textual analysis, to trace the origins, uptake, and effects of these figures. While making vital policy contributions, the numbers have led to some ironic consequences including the fostering of gay youth identification with suicide as a potential correlate of their identity and the potential antigay redeployment of decontextualized numbers. They have also led to a reaction in the form of “resilience” narratives. (shrink)

Theoria, EarlyView. -/- In his recent book Thin Objects, Øystein Linnebo (2018) argues for the existence of a hierarchy of abstract objects, sufficient to model ZFC, via a novel and highly interesting argument that relies on a process called dynamic abstraction. This paper presents a way for a nominalist, someone opposed to the existence of abstract objects, to avoid Linnebo's conclusion by rejecting his claim that certain abstraction principles are sufficient for reference (RBA). Section 1 of the paper explains (...) Linnebo's argument for RBA. It offers a reading of Linnebo's work upon which he has two arguments for RBA: one deductive and one abductive, and argues that whilst the deductive argument is unsound the abductive one is prima facie plausible. The nominalist must therefore find a way to respond to the abductive argument. Section 2 outlines just such a response, by offering an alternative explanation of the cases Linnebo wishes to argue from. Most interestingly, it shows that abstraction in Linnebo's most difficult case (the “reference to ordinary bodies” case) can be achieved using mereological means, rather than relying on RBA.

The author describes and examines Ian Hacking’s approach to historical ontology and its application to psychological description. Historical ontology is concerned with the study of phenomena that come in and out of being. Phenomena under psychological description not only are historical, but also are particularly susceptible to what Hacking calls dynamic nominalism. Dynamic nominalism characterizes the ways our descriptive practices of naming interact with things named. More precisely, in describing ourselves psychologically, we humans are uniquely capable (...) of reacting to such self-descriptions in ways that can constitute or reconstitute a relation with ourselves. Humans come to define and act toward themselves under psychological descriptions and, in the process, form and alter the kinds of persons they are. Furthermore, it is suggested that an indispensible precondition of historical ontology, and all that is entailed by it, is a uniquely human agency that not only is responsive to psychological descriptions, but also is self-interpreting and self-determining. The author concludes with some impressions about historical ontology and psychological description and their implications for psychology. 2012 APA, all rights reserved). (shrink)

Within ontology new theories are extremely rare. Hacking bravely claims to have one: "historical ontology" or "dynamic nominalism." Regrettably, he uses "nominalism" idiosyncratically, without explaining it or its qualifier. He does say what historical ontology is: it is "the presentation of the history of ontology in context." This idea is laudable, as it invites presenting idealism as once attractive but no longer so (due to changes in perception theory, for example). But this idea is a proposal, not (...) a theory, muchless an ontological theory, as it does not say what things are made of. Also, Hacking's details are often misleading. Thus, he falsely hints that he respects Wittgenstein and that he agrees with him. Considered as a study of ontology sans its (often amusing) incidental material, it appears surprisingly thin and repetitious. The study is either excessively opaque or quite clear but stale: the choice between these options is open. Key Words: Ian Hacking • Michel Foucault • ontology • contextualism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Mild Cognitive Impairment:Which Kind Is It?Andy Hamilton (bio)Keywordshuman kinds, mild cognitive impairment, multiple personality disorder, practical kinds, social constructionThere is much stimulating material in the Graham and Ritchie's paper (2006), concerning not just disease-classification but also the ethics of diagnosis. My concern is with the way in which they adduce Ian Hacking's views in the philosophy of science in support of their own. The authors quote with approval his (...) "dynamic nominalism" and its influence on Zachar's concept of "practical kinds." Hacking's view, as the authors quote it, is that "People classified in a certain way tend to conform to or grow into the ways that they are described; but they also evolve in their own ways, so that the classifications and descriptions have to be constantly revised" (1995, 21). The act of classifying changes both the classifier and the subject of classification, resulting in facts and categories that are both socially created and real. Hacking calls this "the looping effect of human kinds," and comments that "Multiple personality [disorder] is an almost too perfect illustration of this feedback effect" (1995, 21). The authors comment that Zachar (2000) builds on Hacking's position, discarding essentialist notions of classification that are limited to inherent biological properties, and turning instead to "practical kinds—nonarbitrary cultural artifacts intended to meet pragmatic needs (e.g. therapeutic, predictive prognostic, labeling effects, and physiology)" (Graham and Ritchie 2006, 36). Practical kinds, they believe, offer a way out of the clinical approach focused on mild cognitive impairment (MCI) as a precursor to, or mild form of, Alzheimer's disease. The inclination of the authors, as I read them, is to treat MCI as a practical or human kind, and not, like Alzheimer's disease, as a natural kind.My concern is whether the "looping effect of human kinds" can be transferred to the case of MCI from Hacking's original case study in Rewriting the Soul, multiple personality disorder (MPD). Hacking wished there to undermine the traditional debate over whether MPD is a "social or psychiatric artifact." He claims, correctly I think, that the presupposition behind the question "Is MPD a real disorder as opposed to a product of social circumstances?" should be rejected. The fact that a disorder is a product of social circumstances does not make it less real (1995, 12). On the looping of human kinds, Hacking comments that "The concept of child abuse [implicated in MPD] may itself be so made and molded by attempts at knowledge and intervention, and social reaction to these studies, that there is no stable object, child abuse, to have knowledge about." This is a "no fact of the matter" response, and it [End Page 51] is based on the recognition of conceptual change. He later adds that child abuse "is a real evil, and it was so before the concept was constructed. It was nevertheless constructed. Neither reality nor construction should be in question" (1995, 61, 68). However, Hacking's conclusions about the reality of MPD express only a muted skepticism. Utilitarian skeptics approach this question by asking, "What is the most effective treatment?" Hacking writes that "in their hearts [such skeptics] suspect that the outcome of multiple therapy [therapy that condones or even encourages the development of multiples in the patient] is a type of false consciousness" (1995, 267). The skeptics about MPD are making a moral judgment, he believes; but on whether that moral judgment is correct, he is silent, although the suspicion must be that he agrees with it.How do these considerations apply to the case of MCI? Graham and Ritchie rightly note that classifying a subject as suffering from MCI, and informing them of the diagnosis, will affect them adversely—it will cause suffering not least because there is at present no cure. However, it must surely be conceded that any disease at all—physical or mental—is a social entity insofar as it involves behavioral ascriptions to the subject concerning their incapacity. The authors also note the vested interests—especially from the pharmaceutical industry—in developing a diagnostic category of MCI. These interests are present in the development of any significant diagnostic... (shrink)

Nature, as Spinoza conceives of it, contains individual things or finite modes, each with its own essence. Although we humans classify individuals into kinds, Spinoza is adamant that the resulting types or species “are nothing”. Despite Spinoza's nominalism, his mature works posit differences between animal kinds that are discoverable by reasoning and available to philosophical understanding. Spinoza's world is fluid in the sense that the powers of individuals are in flux, changing as they interact with one another. In Spinoza's (...) view, changes in an individual's power are typically the effects of its interactions with external things. Spinoza contrasts the affective dynamics between human natures with a lack of affective commonality between humans and other kinds of animals. In his political works Spinoza translates his account of natures or essences into juridical terms. The claim that mutual sociability is what makes an animal kind is of a piece with the rest of Spinoza's philosophy. (shrink)

In “Race, Multiculturalism, and Democracy,” Robert Gooding-Williams offers an insight. He writes: “Our sense of ourselves and of the possibilities existing for us is, to a significant degree, a function of the descriptions we have available to us to conceptualize our intended actions and prospective lives. . . . ‘Hence if new modes of description come into being, new possibilities of action come into being in consequence.’” In this article, I discuss the philosopher’s role in the articulation of new descriptions (...) and thus new possibilities. I argue that potential modes of bold and assertive comportment are conjured when new insurrectionist descriptions are articulated within oppressed populations. To bring this to a higher resolution, I discuss the pervasiveness of dialectical conflict, the need to creatively reorient the descriptions of oppressed groups toward liberation, and the need for more than one prescriptive mode of social amelioration.

What is the proper metaphysics of quantum mechanics? In this dissertation, I approach the question from three different but related angles. First, I suggest that the quantum state can be understood intrinsically as relations holding among regions in ordinary space-time, from which we can recover the wave function uniquely up to an equivalence class (by representation and uniqueness theorems). The intrinsic account eliminates certain conventional elements (e.g. overall phase) in the representation of the quantum state. It also dispenses with first-order (...) quantification over mathematical objects, which goes some way towards making the quantum world safe for a nominalistic metaphysics suggested in Field (1980, 2016). Second, I argue that the fundamental space of the quantum world is the low-dimensional physical space and not the high-dimensional space isomorphic to the ``configuration space.'' My arguments are based on considerations about dynamics, empirical adequacy, and symmetries of the quantum mechanics. Third, I show that, when we consider quantum mechanics in a time-asymmetric universe (with a large entropy gradient), we obtain new theoretical and conceptual possibilities. In such a model, we can use the low-entropy boundary condition known as the Past Hypothesis (Albert, 2000) to pin down a natural initial quantum state of the universe. However, the universal quantum state is not a pure state but a mixed state, represented by a density matrix that is the normalized projection onto the Past Hypothesis subspace. This particular choice has interesting consequences for Humean supervenience, statistical mechanical probabilities, and theoretical unity. (shrink)

This thesis promotes a therapeutic revision of fundamental assumptions in contemporary ontological thought. I show that none of the extant standard theories of objects provides a viable account of the numerical, qualitative, and trans-temporal identity of objects, and that this is due to certain substance-ontological premises. I argue that in order to state the identity conditions of objects we must abandon these premises, together with the idea that objects enjoy ontological primacy. ;I follow a methodological program of formally criticizing an (...) ontological framework by demonstrating that each of the theories developed within this framework is incoherent, i.e., either inconsistent or subject to vicious regress. I proceed in three steps. First, I show that the substance-ontological paradigm cannot be characterized in terms of its basic entities, since there is no extensional, intensional, or functional definition of the notion of substance common to all extant substance ontologies; consequently, I propose to describe the substance-ontological paradigm in terms of its basic assumptions. ;Second, I analyze the contemporary discussion of the problem of individuality, the problem of universals, and the problem of persistence, and uncover 22 characteristic implicit assumptions of substance ontology. I show on the basis of representative examples that, due to their commitment to substance-ontological presuppositions, all extant types of solutions to the three mentioned problems are incoherent. In particular, I take issue with the bare particular view, the qualified particular view, and the bundle view of individuality; different varieties of platonist and nominalist theories of universals and of relational and functional theories of predication; and the endurance and perdurance approaches to persistence. ;Third, while historical process-ontological schemes have dropped some of the revealed substance-ontological presuppositions, I finally explore the result of rejecting all of them and sketch a scheme based on dynamic masses which promises to yield coherent explanations of the ontological features of those complex processes which we commonly consider to be objects.

L'analyse des rapports entre les concepts de temps et de mouvement dans la philosophie première de Hobbes permet de confirmer la dimension dynamique de son matérialisme qui ne prend sens qu'avec la théorie unifiée du conatus. Elle nous conduit aussi à reconsidérer le nominalisme radical qu'on lui attribue généralement, à partir d'une interrogation sur le statut de ce que Hobbes appelle la puissance imaginative. The analysis of the relations between the concepts of time and movement in Hobbes' first philosophy allows (...) that dynamic dimension of his materialism which only takes on meaning with the unified theory of the conatus, to be confirmed. It also leads us to reconsider the radical nominalism that is generally attributed to him, by means of an interrogation of the status of what Hobbes calls imaginative power. (shrink)

This paper is about knowledge construction in music listening. It argues for an experiential approach to music cognition, stressing the dynamic-vectorial field of meaning rather than the symbolic field. Starting from the conceptual framework of deixis and indexical devices, it elaborates on the concept of pointing as a heuristic guide for sense-making which allows the listener to conceive of perceptual elements in terms of salience, valence and semantical weight. As such, the act of (mental) pointing can be predicative, either (...) in a nominalistic or processual way, giving a description of the temporal evolution of a situation as against episodic nominalizations that refer to just one single instance of the process. The latter, especially, are characterized by distancing and polarization between the listener and the music, allowing him/her to deal with the music also at a level of mental imagery and to construct a mental or cognitive map of its unfolding.

When Alain Locke developed a philosophy of valuation that he termed “functional relativism,” he contrasted his position to “value realism,” apparently because he wanted to keep valuations free from being bound to status quo existence. This article considers Locke's philosophy of valuation in relation to the “realism” of Charles S. Peirce in order to show that there is an approach to realism that answers to requirements of dynamic, evolutionary growth and creativity. The argument begins by placing Locke's cardinal values (...) onto a compass-like diagram inspired by Black Elk's ritual acknowledgment of cardinal directions. The illustration of a hoop of valuation is used to explore the usefulness of thinking in terms of diagrams, with explicit reference to Peircean semiotics. Next the article pursues a context of valuation developed through the psychical philosophy of George Herbert Mead and recent work on Peircean realism. It shows how valuation may be viewed as an exercise in freedom, not confined to status quo existence. Sources of error are acknowledged and reviewed. In the end, Peirce's choice of realism versus nominalism is found to be consistent with Lockean commitments to shared living in communities of inquiry. A Lockean philosophy of valuation, therefore, is not necessarily antirealist. (shrink)

The aim of this study is to offer a reflection on the theory of knowledge of Francisco Suárez and his nominalism in the light of Sextus Empiricus’ sceptical thought in his Outlines of Pyrrhonism. It is Sextus who allows us to compare the epistemology of Suárez with a dynamic system of knowledge. With this in view, in the first place, I examine Sextus’s scepticism and Suárez’s nominalist ontology. In the second place, I analyse the mental representation as conceived (...) by Sextus in analogy with the formal and objective concepts of Suárez, and I also discuss the concept of relation in both authors. Finally, I proceed to examine the concept of belief inasmuch as certain restrictions in the configuration of our judgements are manifest and recognized. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Mind of Charles Hartshorne: A Critical Examination by Donald Wayne Viney and George W. ShieldsLeon NiemoczynskiThe Mind of Charles Hartshorne: A Critical Examination. Donald Wayne Viney and George W. Shields. Anoka, MN: Process Century Press, 2020. 584 pp. $40.00 cloth.Over the past decade process philosophy has undergone a significant renaissance most notably due to the towering presence of the thought of Alfred North Whitehead in that tradition. (...) Charles Hartshorne by manner of contrast has not had such a towering presence. Part of the reason this is the case is due to a paucity of introductory literature on the thought of Charles Hartshorne—literature that might contribute to a “starter kit” so to speak in mastering Hartshorne’s massive oeuvre. The Mind of Charles Hartshorne: A Critical Examination by Donald Wayne Viney and George W. Shields, both former students of Hartshorne and experts in process philosophy themselves, have authored a welcome contribution to an introductory literature that will most certainly elevate awareness of Hartshorne’s importance to its rightful place alongside that of Whitehead. The book is successful in its aims of “giving a reasonably comprehensive account of Hartshorne’s philosophy with an eye of presenting his best arguments...” (the “correcting what we see as misunderstandings of his views appearing in the critical literature” part may have been best left out) and “updating Hartshorne scholarship” (viii). There are ten chapters in total, appendix essays, the aforementioned bibliography, endnotes, and name and subject indexes.The Preface situates the mind of Charles Hartshorne as spanning the twentieth century and engaging metaphysics even when it was unfashionable to do so. Hartshorne thought about a wide-ranging and diverse range of subjects in both philosophy and science, aesthetics, metaphysics, applied philosophy, and theology. He never questioned modern science or evolution and believed that while metaphysics and empirical science have different methods each ensures its own way to objectivity. One learns that Hartshorne’s process metaphysics is also called “neo-classical” philosophy or speculative philosophy. His thought “gave full weight to the dynamic, relational, processive temporal and creative, affective dimensions of the universe” (vi). Hartshorne was known as much for his “panentheism,” or view that God transcends nature but also may be found immanently within it, as he was for his critique of traditional or scholastic classical theology—especially in his logic of theism where he recreates a modal version of the ontological argument. [End Page 94]Chapter 1, “The Career and Personality of Charles Hartshorne,” discusses just that. What seemed most important to me was the discussion of Hartshorne’s formative background of reading novels and poetry by Emerson, Melville, or Camus as a way of intensely living, his studying under William Ernest Hocking, and his Sheldon Traveling Fellowship where he studied for a time with Husserl and read and reviewed Heidegger. Probably the most important biographical details are that Hartshorne was given the assignment of editing the Peirce papers along with Paul Weiss as a Research Fellow while at Harvard University and he also met and graded for Whitehead, who along with C.S. Peirce, would become the twin pillars of all his thinking as a “Peircean and Whiteheadian” (11). From Peirce, we learn that Hartshorne took “possibility is best conceived of as a continuum with no least member” and from Whitehead, “actuality is discrete and discontinuous (atomistic), composed of momentary flashes of experiences” (11). For Hartshorne process and relativity are metaphysically basic.Chapter 2 begins with Hartshorne’s idea that, “Nature comes to us as constituted by feelings, not as constituted by lifeless, insentient matter” (28). Reality has an affective tone in which there is a layered complexity of feeling and social relation. In other words, contra Locke or Hume, feeling is objectively part of an objective affective continuum and is not nominalistically “painted on bare sense impressions” (46). Such might be described as a doctrine of “panexperientialism”— “the view that the basic constituents of reality are flashes of experience” (46). Experience and feeling stretch in their continuity to meet the bounds of nature. Chapter two continues with a wonderful discussion of Hartshorne’s aesthetics: “beauty is the mean between extremes” (48).Chapter 3 provides a... (shrink)

This paper confronts a certain modern view of the relation between semantics and ontology with that of the late-medieval nominalist philosophers, William Ockham and John Buridan. The modern view in question is characterized in terms of what is called here “the thesis of onto-semantic parallelism,” which states that the primitive (indefinable) categorematic concepts of our semantics mark out the primary entities in reality. The paper argues that, despite some apparently plausible misinterpretations to the contrary, the late-medieval nominalist program of “ontological (...) reduction” was not driven by considerations that try to “read off” ontology from semantic analysis or those that try to identify semantic primitives in their search for ontological primitives. The medieval authors presented a much more flexible, dynamic view of “Aristotelian naturalism,” which challenges both of the unappealing modern alternatives of “conceptual tribalism” and “conceptual imperialism.”.

This article proposes an integrative reading of Peirce's and James's philosophies, which aims to figure out the main features of a shared pragmatist metaphysics. Two methodologies are adopted to reach this goal: a historical scrutiny of sources, prevalent in the first part, and a theoretical investigation of Peirce's and James's philosophies, in the second and third parts. The first part analyzes Peirce's and James's proximity, which lies in their common understanding of pragmatism as an anti-dogmatic method in philosophy, and their (...) alleged main difference, which is represented by the issue of nominalism/anti-nominalism, and pivots around the concepts of individuals and generals. The article challenges the mainstream interpretation that sees Peirce as a champion of generality and continuity, whereas James is known for being an ardent defender of individuality. The arguments supporting such an unconventional interpretation are offered in the second part, which explores Peirce's view of individuality in logic, and the third one, dedicated to James's view of continuity in psychology. As a conclusion, Peirce and James's shared pragmatic metaphysics turns out to be centered on the dynamical bonding between individuals and generals. (shrink)

The main characteristic of modern science is that its new theories contain the old ones as their particular cases. In this respect, one can speak of "modern" science only since 17th century discoveries of Galileo, Kepler and Descartes. Yet, one can find certain traits of the modern scientific mode of thinking as early as in 14th century; they include interest in the practical use of science, introduction of experiment and mathematical method. Late medieval science was powerfully influenced by the doctrines (...) of Aristotle, who found the essence of scientific pursuit in establishing the causes of the phenomena observed in the world in the inductive process of abstraction, which has three main stages of generalization: physics, mathematics, and metaphysics. In physics the solutions were hinged on the concept of natural directions and the belief that uniform motion requires permanent application of power. The foundations of Aristotelean physics were first questioned in the 14th century. Duns Scotus and Wiliam of Ockham critically discussed the doctrine of induction, originating the shift of interest towards observation. Peter of Abano started the theory of experiment. Some criticism came from the theologians, who questioned certain limitations of the Aristotelean frame of mind. The main subject of controversy was the concept of vacuum, discussed especially with the reference to motion. Here the Aristotelean standpoint was criticised from the positions of atomism and Platonism by a number of scholars starting from Robert Grosseteste, through Giles of Rome and Nicholas of Autrecourt, to Nicholas of Cusa and Giordano Bruno. Other controversial problems included plurality of the worlds, privileged positions in the universe, circular motion of the earth. Here an important contribution was made by Nicolas Copernicus. Another group of scholars, which helped to overcome Aristoteleanism, was the so-called Merton school of Oxford. Their new theories of motion, which distinguished between its kinematic and dynamic aspects, quickly spread through Europe and are said to have influenced Galileo. Yet another source of inspiration was found by Galileo in the views of the nominalist school of Paris, notably Nicholas of Oresme and John Buridan. By reaping the benefit of their innovations and overcoming their deficiencies Galileo was able to lay foundations for the modern science, first fully formulated by Newton. (shrink)

Discussion of divine providence was traditionally grounded in the wisdom and benevolence of the Creator, until the impact of nominalism which narrowed the theological focus upon the absolute power and freedom of the divine will. An exemplary approach for discussing providence which predates nominalism and which has surprising contemporary relevance is the one developed by Thomas Aquinas in his Summa Theologiae. It is exemplary both for how it discusses providence and for what is says about it. Methodologically, Aquinas (...) explains providence in two contexts, one theological, the other cosmological, in order to avoid misconstruing the reality of one term because of the dynamics pertinent to the other. Substantively, this understanding of providence rests upon the theological foundation of the Creator’s wisdom and benevolence, which in the world find expression as a comprehensive order oriented towards emergent goodness. Through this order God is provident by the genuine and contingent causal actions of creatures, a natural and non‐deterministic means that makes it highly compatible with modern science. (shrink)

The study is aimed at clarifying Meister Eckhart's theory of relations, which involves all fields of his philosophy: gnoseological, theological, ontological. Its general features (concerning the ontological status of relations and relatives, the nature of the fundamentum relationis, and the origin ab altero proper to the relation) seem to denote a realist position, in opposition to the Nominalism. Yet, when he applies the theory to particular problems, it is evident that his position cannot be simply qualified as a realist (...) one. In Eckhart's view, the objectivity of knowledge is not guaranteed by the correspondence between the extra-mental entities and their images in the mind, but by the close relationship between the subject and the object of knowledge. This same dynamic relationship (a sort of inclusion) holds between the Father and the Son and between God and the creatures: the Son is the image of the Father, who is inside him, like the creature is the image of God, who is the inner ontological foundation of the creature.

The article surveys the development of james' views on the status of the psychological subject (self); the uncertainties and hesitations in james' views are pointed out. But, Contrary to the prevailing view, Upheld especially by john dewey and ralph b perry, James' article "does consciousness exist?" in 1904 does not represent the final stage of his thought. This can be found only in his last book "a pluralistic universe" six years later in which the existence of the "full self" is (...) reasserted. James reached this conclusion after the period of intense intellectual struggle which can be traced in the private notes and drafts published by r b perry. The idea of dynamic self was consonant with the process philosophy which james finally adopted. (shrink)

A cluster of similar trends emerging in separate fields of science and philosophy points to new opportunities to apply biosemiotic ideas as tools for conceptual integration in theoretical biology. I characterize these developments as the outcome of a “relational turn” in these disciplines. They signal a shift of attention away from objects and things and towards relational structures and processes. Increasingly sophisticated research technologies of molecular biology have generated an enormous quantity of experimental data, sparking a need for relational approaches (...) that could help to find recurrent patterns in the mass of data. Earlier conceptions of relational biology and cybernetics, once deemed too abstract and speculative, are now resurrected and applied by means of new computational and simulation tools. I think this receptivity should be extended to incorporate nets of semiotic relations as heuristic guides for discerning global patterns of interactions in living systems. In this article I review aspects of systems biology and new directions in evolutionary theory, focusing on the role of circular and downward causation in relational structures and dynamical networks. I also indicate promising avenues of integration of some ideas of biosemiotics with those emerging from these new currents in biology. Relational developments in biology bear a telling similarity to a parallel relational turn presently manifest in the philosophy of science, rooted in the philosophy of physics and mathematics and in different varieties of structural and informational realism. The recognition of the relational nature of reality within these disciplines entails a tacit repudiation of nominalistic biases in science that have hindered the reception of semitiotic conceptions in biology. In previous investigations I explored connections between two kinds of relational structures: the networks of self-referential circular loops that appear pervasively in living systems, and the triadic relational structures that Peircean semiotics places at the basis of all semiotic transactions. Current relational views in the sciences seem oblivious to the difference between dyadic and triadic relations. Incorporating this essential distinction from biosemiotics into other fields could be a first step in seizing the opportunities opened by the relational turn for a renewal of biology and of natural philosophy in general, across disciplinary boundaries.

The subject matter of this thesis is analytic ontology. Chapters II and III deal with two versions of trope theory, or moderate nominalism; these are defined as ontologies which recognise properties and relations but no (real) universals. The key notion of both theories, trope, is characterised as an abstract particular. What the abstractness amounts to differs between the two. Yet another difference is that simplicity is an essential trait of a trope according to one theory, but not according to (...) the other. Though exact similarity is said to play an important role in both theories, as it turns out, this does not seem to be the case. The ontology dealt with in chapter IV is a mixture of moderate nominalism concerning qualities and realism concerning relations. In it, quality instances (moments) and universal relations are the ultimate constituents of the universe. While relations and moments are considered to be constituents of states of affairs, which are characterised as objects of higher orders, complexes that are objects of the first order are made up of moments on their own. Among these complexes one finds the ordinary objects. Paradoxically, although relations are necessary for the existence of complex first order objects, relations are not thought to be among the contents of these objects. The main subject of chapter V is a particular version of moderate realism; it is an ontology which is realistic in its recognition of universals and moderate in its recognition of instances of these universals. Instances combine to form complex networks. A theoretically motivated claim is that although each instance has a predicational aspect as well as a universal one, it is simple in the sense of lacking internal predicative structure; though, this claim can be called into question. Keywords: analytic ontology, moderate nominalism, moderate realism, particular, universal, abstract, concrete, abstract particular, abstract universal, concrete particular, concrete universal, trope, moment, complex unity, collection, instance, unit attribute, intensional aspect, predicational aspect, continuous composite, articulated composite.

Ian Hacking’s wide-ranging and penetrating analysis of science contains two well-developed lines of thought. The first emphasizes the contingent history of our inquiries into nature, focusing on the various ways in which our concepts and styles of reasoning evolve through time, how their current application is constrained by the conditions under which they arose, and how they might have evolved differently. The second is the mistrust of the idea that the world contains mind-independent natural kinds, preferring nominalism to ‘inherent (...) structurism’. These two pillars of thought seem at first to be mutually reinforcing: the lack of natural structure can help make sense of scientific variability and revision, while variability and revision provide reason to suspect that natural structure is little more than idealization. In what follows, I argue that these two pillars not only fail to support each other, but in fact conflict. One of them must fall, and it is clear which. (shrink)

Gardeners, poets, lovers, and philosophers are all interested in the redness of roses; but only philosophers wonder how it is that two different roses can share the same property. Are red things red because they resemble each other? Or do they resemble each other because they are red? Since the 1970s philosophers have tended to favour the latter view, and held that a satisfactory account of properties must involve the postulation of either universals or tropes. But Gonzalo Rodriguez-Pereyra revives the (...) dormant alternative theory of resemblance nominalism, showing first that it can withstand the attacks of such eminent opponents as Goodman and Armstrong, and then that there are reasons to prefer it to its rival theories. The clarity and rigour of his arguments will challenge metaphysicians to rethink their views on properties. (shrink)

Gonzalo Rodriguez-Pereyra offers a fresh philosophical account of properties. How is it that two different things (such as two red roses) can share the same property (redness)? According to resemblance nominalism, things have their properties in virtue of resembling other things. This unfashionable view is championed with clarity and rigor.

Nominalism, which has its origins in the Middle Ages and continues into the Twenty-First Century, is the doctrine that there are no universals. This book is unique in bringing together essays on the history of nominalism and essays that present a systematic discussion of nominalism. It introduces the reader to the distinction between particulars and universals, to the difficulties posed by this distinction, and to the main motivations for the rejection of universals. It also describes the main (...) varieties of nominalism about properties and provides tools to understand how they developed in the history of Western Philosophy. All essays are new and are written by experts on the topic, and they advance the discussion about nominalism to a new level. (shrink)

This chapter is a discussion of Class and Resemblance Nominalism. According to the traditional versions of these theories, properties are classes of particulars. Thus, the property of being red is the class of red particulars, and the property of being square is the class of square particulars. Several objections have been advanced against these theories, and one of the most powerful of such objections is the so-called Coextension Difficulty, according to which Class and Resemblance Nominalism have to wrongly (...) identify distinct but coextensive properties. After discussing the nature of Class and Resemblance Nominalism, some problems of these theories and how they can be deal with, the superiority of Class and Resemblance Nominalism over other theories of properties and the superiority of Resemblance Nominalism over Class Nominalism, I concentrate on the Coextension Difficulty. With respect to this I argue that Class and Resemblance Nominalism can be developed in such a way that they admit properties without identifying them with classes, and this allows them to avoid the Coextension Difficulty, since such versions of these theories are not forced to wrongly identify distinct but coextensive properties. Thus the Coextension Difficulty is not a lethal problem for Class and Resemblance Nominalism. (shrink)

‘Grounding and the indispensability argument’ presents a number of ways in which nominalists can use the notion of grounding to rebut the indispensability argument for the existence of mathematical objects. I will begin by considering the strategy that puts grounding to the service of easy-road nominalists. I will give some support to this strategy by addressing a worry some may have about it. I will then consider a problem for the fast-lane strategy and a problem for easy-road nominalists willing to (...) accept Liggins’ grounding strategy. Both are related to the problem of formulating nominalistic explanations at the right level of generality. I will then consider a problem that Liggins only hints at. This problem has to do with mathematics’ function of providing the sort of covering generalizations we need in scientific explanations. (shrink)

1. 1. PROGRAM It will be our aim to reconstruct, with precision, certain views which have been traditionally associated with nominalism and to investigate problems arising from these views in the construction of interpreted formal systems. Several such systems are developed in accordance with the demand that the sentences of a system which is acceptable to a nominalist must not imply the existence of any entities other than individuals. Emphasis will be placed on the constructionist method of philosophical analysis. (...) To follow this method is to introduce the central notions of the subject-matter to be investigated into a system governed by exact rules. For example, the constructionist method of investigating the properties of geometric figures may consist in formulating a system of postulates and definitions which, together with the apparatus of formal logic, generates all necessary truths concerning geometric figures. Similarly, a constructionist analysis of the notion of an individual may take the form of an axiomatic theory whose provable assertions are just those which seem essential to the role played by the concept of an individual in system atic contexts. Such axiomatic theories gain in interest if they are supple mented by precise semantical rules specifying the denotation of all terms and the truth conditions of all sentences of the theory.

In "nominalism and realism" armstrong carefully demolishes various nominalist responses to plato's "one over many" problem but simply dismissed the quinean response as "ostrich nominalism". The paper argues that plato's problem is pseudo. So to ignore it is not to behave like an ostrich. Rather to adopt realism because of this problem that isn't there is to be a "mirage realist." there are some good reasons that lead armstrong to realism but he is largely a mirage realist. Quine (...) does not ignore any real problem for nominalism and so is not an ostrich nominalist. (shrink)

The traditional possible-worlds model of belief describes agents as ‘logically omniscient’ in the sense that they believe all logical consequences of what they believe, including all logical truths. This is widely considered a problem if we want to reason about the epistemic lives of non-ideal agents who—much like ordinary human beings—are logically competent, but not logically omniscient. A popular strategy for avoiding logical omniscience centers around the use of impossible worlds: worlds that, in one way or another, violate the laws (...) of logic. In this paper, we argue that existing impossible-worlds models of belief fail to describe agents who are both logically non-omniscient and logically competent. To model such agents, we argue, we need to ‘dynamize’ the impossible-worlds framework in a way that allows us to capture not only what agents believe, but also what they are able to infer from what they believe. In light of this diagnosis, we go on to develop the formal details of a dynamic impossible-worlds framework, and show that it successfully models agents who are both logically non-omniscient and logically competent.

Dispositional Essentialism, as commonly conceived, consists in the claims that at least some of the fundamental properties essentially confer certain causal-nomological roles on their bearers, and that these properties give rise to the natural modalities. As such, the view is generally taken to be committed to a realist conception of properties as either universals or tropes, and to be thus incompatible with nominalism as understood in the strict sense. Pace this common assumption of the ontological import of Dispositional Essentialism, (...) the aim of this paper is to explore a nominalist version of the view, Austere Nominalist Dispositional Essentialism. The core features of the proposed account are that it eschews all kinds of properties, takes certain predicative truths as fundamental, and employs the so-called generic notion of essence. As I will argue, the account is significantly closer to the core idea behind Dispositional Essentialism than the only nominalist account in the vicinity of Dispositional Essentialism that has been offered so far—Ann Whittle’s Causal Nominalism—and is immune to crucial problems that affect this view.

I argue that constructive nominalism is preferable to scientific realism. Rather than reflecting without distortion the way the mind-independent world is, theories refract. They provide an understanding of the world as modulated by a particular theory. Truth is defined within a theoretical framework rather than outside of it. This does not undermine objectivity, for an assertion contains a reference to the framework in terms of which its truth is claimed.

Nominalism about attributes has serious difficulties in accounting for truths involving abstract nouns. Prominent among such truths are statements of comparative similarity among attributes. This paper argues that one cannot account for the truth of such statements without invoking attributes.

In this dissertation I consider the merits of certain nominalist accounts of phenomena related to the character of ordinary objects. What these accounts have in common is the fact that none of them is an error theory about standard cases of predication and none of them deploys God or uniquely theistic resources in its explanatory framework. -/- The aim of the dissertation is to answer the following questions: -/- • What is the best nominalist account on offer? • How might (...) it be improved? • Does it ultimately succeed? -/- I will argue that while so-called trope theory is the best account on offer, it can be significantly improved—or replaced—by a novel version of nominalism that is modeled after trope theory. Ultimately, however, I will argue that even the novel version fails. -/- The dissertation unfolds as follows. In Chapter 1, I introduce Austere Nominalism (AN), which is perhaps the most extreme version of nominalism that falls within the scope of the dissertation. AN is often described as the view that there exist only concrete particulars. According to AN, it is unnecessary to posit any entities other than ordinary objects—turkeys, tables, and the like—in order to account for explananda related to the character of those objects. (Such explananda include the phenomenon of attribute agreement, of attribute possession, of true subject-predicate sentences, etc.) In this chapter I argue that AN fails to provide an adequate account of these explananda. In addition, introducing and criticizing AN serves an important heuristic role for the rest of the dissertation. To understand this role, we must distinguish between the basic explanatory strategy deployed by the austere nominalist and the type of explananda for which she deploys that strategy. The austere nominalist deploys the strategy to account for the character of ordinary objects. As I argue in Chapter 1, this deployment is a failure. As I go on to show in Chapter 2, the widespread rejection AN has led to a variety of rival accounts of the character of ordinary objects. In rejecting AN, however, these accounts also tacitly reject its basic explanatory strategy. Thus goes the baby with the bathwater, since, arguably, there are some attractive features of AN’s basic explanatory strategy. Indeed, those who defend the most prominent version of nominalism—trope theory—seem to overlook the advantages of AN’s basic strategy, and by so doing, make an unnecessary concession to the realist. Or so I argue in Chapter 3. And, as I will argue in Chapter 4, the strongest version of nominalism is a novel account, modeled after trope theory, that deploys AN’s basic strategy at a more fundamental level than that of ordinary objects. This novel account—troper theory—is closer in spirit to AN than is traditional trope theory. (Thus, AN serves as a foil for the discussion of other nominalist views.) Finally, in the Afterword I indicate how troper theory is equally vulnerable to some of the traditional objections that plague trope theory. Thus, if you are not convinced that traditional objections to trope theory are conclusive and you want to be a nominalist, then you should abandon trope theory and adopt troper theory. If you take traditional objections against trope theory to have significant force, then you should reject both theories. (shrink)

The article considers, in a historical setting, the links between varieties of nominalism—the extreme nominalism of the Quine-Goodman variety and the trope nominalism current today—and types of idealism. In so doing arguments of various twentieth century figures, including Husserl, Bradley, Russell, and Sartre, as well as a contemporary attack on relations by Peter Simons are critically examined. The paper seeks to link the rejection of realism about universals with the rejection of a mind-independent “world”—in short, linking (...) class='Hi'>nominalism with idealism. (shrink)

Bertrand Russell argued that any attempt to get rid of universals in favor of resemblances fails. He argued that no resemblance theory could avoid postulating a universal of resemblance without falling prey to a vicious infinite regress. He added that admitting such a universal of resemblance made it pointless to avoid other universals. In this paper I defend resemblance nominalism from both of Russell's points by arguing that (a) resemblance nominalism can avoid the postulation of a universal of (...) resemblance without falling into a vicious infinite regress, and (b) even if resemblance nominalism had to admit a universal of resemblance, this would not make it pointless to avoid postulating other universals.

My aim in this paper is to offer a Hegelian critique of Quine’s predicate nominalism. I argue that at the core of Hegel’s idealism is not a supernaturalist spirit monism, but a realism about universals, and that while this may contrast to the nominalist naturalism of Quine, Hegel’s position can still be defended over that nominalism in naturalistic terms. I focus on the contrast between Hegel’s and Quine’s respective views on universals, which Quine takes to be definitive of (...) philosophical naturalism. I argue that there is no good reason to think Quine is right to make this nominalism definitive of naturalism in this way – where in fact Hegel offers a reasonably compelling case that science itself requires some commitment to realism about universals, kinds, etc. Furthermore, even if Hegel is wrong about that, at least his case for realism is still a naturalistic one, as it is based on his views on concrete universality, which is an innovative form of in rebus realism about unive..

This monograph details a new solution to an old problem of metaphysics. It presents an improved version of Ostrich Nominalism to solve the Problem of Universals. This innovative approach allows one to resolve the different formulations of the Problem, which represents an important meta-metaphysical achievement. In order to accomplish this ambitious task, the author appeals to the notion and logic of ontological grounding. Instead of defending Quine’s original principle of ontological commitment, he proposes the principle of grounded ontological commitment. (...) This represents an entirely new application of grounding. Some metaphysicians regard Ostrich Nominalism as a rejection of the problem rather than a proper solution to it. To counter this, the author presents solutions for each of the formulations. These include: the problem of predication, the problem of abstract reference, and the One Over Many as well as the Many Over One and the Similar but Different variants. This book will appeal to anyone interested in contemporary metaphysics. It will also serve as an ideal resource to scholars working on the history of philosophy. Many will recognize in the solution insights resembling those of traditional philosophers, especially of the Middle Ages. (shrink)

It is widely assumed that platonism with respect to a discourse of metaphysical interest, such as fictional or mathematical discourse, affords a better account of the semantic appearances than nominalism, other things being equal. Of course, other things may not be equal. For example, platonism is supposed to come at the cost of a plausible epistemology and ontology. But the hedged claim is often treated as a background assumption. It is motivated by the intuitively stronger one that the platonist (...) can take the semantic appearances at ‘face-value’ while the nominalist must resort to ad hoc and technically problematic machinery in order to explain those appearances away. In this article, I argue that, on any natural construal of ‘face-value’, the platonist, like the nominalist, is not able to take the semantic appearances at face-value. And insofar as the nominalist is forced to resort to ad hoc and technically awkward devices in order to explain those appearances away, the platonist must resort to such devices as well. One moral of the story is that the thesis that platonism affords a better account of the semantic appearances than nominalism – even other things being equal – is not trivial. Another is that we should rethink a widespread methodology in metaphysics. (shrink)

It is a familiar point that we can use generic sentences to express generalisations that are tolerant to exceptions and then go on to state those exceptions explicitly. It is a less familiar point that switching the order of the generics has deleterious effects on their felicity. For example, the sequences ‘Ravens are black, but albino ravens aren’t’ is perfectly felicitous and judged to be true, whereas its reverse ‘Albino ravens aren’t black, but ravens are’ is infelicitous and contradictory-sounding. This (...) paper argues that such sequences pose a problem for extant theories of generics: while they have no trouble predicting the felicity of the first sequence of generics, they are unable to explain why reversing the order results in infelicity. I propose to account for these observations by adopting a dynamic semantic theory of generic sentences. (shrink)
