Metaphysics has had a long history of debate over its viability, and substantivity. This thesis explores issues connected to the realism question within the domain of metaphysics, ultimately aiming to defend a realist, substantive metaphysics by responding to so-called deflationary approaches, which have become prominent, and well supported within the recent metametaphysical and metaontological literature. To this end, I begin by examining the changing nature of the realism question. I argue that characterising realism and anti-realism through theories of truth unduly (...) places epistemology prior to ontology, and is unwarranted in assuming a non-neutrality between theories of truth and positions within the realism debate. I therefore propose a characterisation of realism and anti-realism understood through truthmaking. This produces a suitable working characterisation of realism that will be used within the remainder of this project. In the second section, I trace the historical influences upon current deflationary approaches to metaphysics, most prominently those of Carnap, and Putnam. I argue that Quine’s supposed attack on Carnap’s anti-metaphysical thought fails, and show how current deflationary thought, most prominently exhibited by Hirsch, came to focus on linguistically derived concerns over the substantivity of metaphysics. In the third section, I outline a number of issues for the deflationist, and defend the coherency and legitimacy of the unrestricted existential quantifier. Focusing on the linguistic aspect of deflationism, I argue that the conception of language that the deflationist relies upon lacks suitable empirical and theoretical support within linguistics and other related domains. Furthermore, I suggest that linguistic analysis in fact supports the claim that the quantifier carries no inherent restrictions. This restores our ability to suitably posit the unrestricted existential quantifier, as a quantifier wherein the domain is only restricted by metaphysically substantive restrictions. Through this, I argue that metaphysics is a substantive domain of discourse. Lastly, I sketch a positive account of how, under an empirically and theoretically justified conception of language, metaphysics can be coherently held to be a realist, substantive enterprise, contra claims that hold that the nature of language inherently prevents metaphysics being considered to be a substantive domain of discourse.

Recent work on Natural Kind Essentialism has taken a deflationary turn. The assumptions about the grounds of essentialist truths concerning natural kinds familiar from the Kripke-Putnam framework are now considered questionable. The source of the problem, however, has not been sufficiently explicated. The paper focuses on the Twin Earth scenario, and it will be demonstrated that the essentialist principle at its core (which I call IDENT)—that necessarily, a sample of a chemical substance, A, is of the same kind as another (...) sample, B, if and only if A and B have the same microstructure—must be re-evaluated. The Twin Earth scenario also assumes the falsity of another essentialist principle (which I call INST): necessarily, there is a 1:1 correlation between (all of ) the chemical properties of a chemical substance and the microstructure of that substance. This assumption will be questioned, and it will be argued that, in fact, the best strategy for defending IDENT is to establish INST. The prospects for Natural Kind Essentialism and microstructural essentialism regarding chemical substances will be assessed with reference to recent work in the philosophy of chemistry. Finally, a weakened form of INST will be presented. (shrink)

I offer a diagnosis of the parallelism between the Doctrine of Potential Parts and the Doctrine of Potential Wholes and briefly examine its bearing on Johansson’s account of the Tibbles-Tib Problem.

There has been much criticism of the idea that Friston's free-energy principle can unite the life and mind sciences. Here, we argue that perhaps the greatest problem for the totalizing ambitions of its proponents is a failure to recognize the importance of evolutionary dynamics and to provide a convincing adaptive story relating free-energy minimization to organismal fitness.

I examine the views of Thomas Reid with respect to a certain version of the problem of induction: Why are inductions using natural kinds successful, and what justifies them? I argue that while both Reid holds a kind of conventionalist view about natural kinds, this conventionalism has a realistic component which allows him to answer both questions.

In this paper we discuss the role that individual and collective acts of interpretation play in shaping a metaphysics of food. Our analysis moves from David Kaplan’s recent contention that food is always open to interpretation, and substantially expands its theoretical underpinnings by drawing on recent scholarship on food and social ontology. After setting up the terms of the discussion (§1), we suggest (§2) that the contention can be read subjectively or structurally, and that the latter can be given three (...) sub-readings. We then lay out (§3) three case studies that, we submit, any viable theory of a metaphysics of food should be able to account for. We show that one structural reading—based on the idea of negotiation—swiftly accommodates for the three case studies. We thus conclude that this reading is most promising for charting a metaphysics of food. (shrink)

This paper aims at understanding the concept of convention in mechanics as a notion transferred from the field of jurisprudence. This enables us to clarify it as a new epistemic category having a pertinent role in the transformation of mechanics in the nineteenth century. Such understanding permits a separation from linguistic and arbitrary conventions, thus highlighting its epistemic features and not transforming fundamental principles into mere arbitrary agreements. After addressing the main references in the literature discussing the role of convention (...) in mechanics, we analyze its classical use as a concept originating from law. Then we explain its use by Carl G. Jacobi, Ferdinand F. Reech, and J. Henri Poincaré. Here we also show how their uses conform to the features analyzed regarding conventions in jurisprudence. Finally, we try to explain how the use of this concept, among other factors, contributed to the transformation of mechanics. (shrink)

In robustness analysis, hypotheses are supported to the extent that a result proves robust, and a result is robust to the extent that we detect it in diverse ways. But what precise sense of diversity is at work here? In this paper, I show that the formal explications of evidential diversity most often appealed to in work on robustness – which all draw in one way or another on probabilistic independence – fail to shed light on the notion of diversity (...) relevant to robustness analysis. I close by briefly outlining a promising alternative approach inspired by Horwich’s (1982) eliminative account of evidential diversity. (shrink)

This paper defends the idea that there must be some joints in reality, some correct way to classify or categorize it. This may seem obvious, but we will see that there are at least three conventionalist arguments against this idea, as well as philosophers who have found them convincing. The thrust of these arguments is that the manner in which we structure, divide or carve up the world is not grounded in any natural, genuine boundaries in the world. Ultimately they (...) are supposed to pose a serious threat to realism. The first argument that will be examined concerns the claim that there are no natural boundaries in reality, the second one focuses on the basis of our classificatory schemes, which the conventionalist claims to be merely psychological, and the third considers the significance of our particular features in carving up the world, such as physical size and perceptual capabilities. The aim of this paper is to demonstrate that none of these objections succeed in undermining the existence of genuine joints in reality. (shrink)

Bruineberg and collaborators distinguish three philosophical positions about the status of Markov blankets in the context of active inference modelling, namely: literalism, realism, and instrumentalism. They criticize the first two positions and suggest that instrumentalism is “less problematic but also less interesting” (sect. 6.1.2, para. 5) Here, I sketch how literalists and realists might reply to Bruineberg et al.'s criticisms, and I explain why instrumentalism is more interesting and contentious than what Bruineberg and collaborators suggest.

This paper advocates a new reading of Nelson Goodman’s new riddle of induction. According to Ian Hacking, this famous problem conveys a “pure nominalism”, as it grounds Goodman’s denial regarding the existence of natural kinds. While this interpretation is somewhat convincing, it suffers the major flaw of not corresponding to what Goodman himself understood by “nominalism”. Nominalism, in a goodmanian sense, is indeed primarily a technical demand, which stems from the so-called “calculus of individuals”. I argue that this mereological definition (...) of nominalism allows to understand the new riddle of induction afresh. As a result, Goodman’s riddle is “hyper-nominalist”, i.e., nominalist in a distinct and stronger sense than what Hacking suggested. (shrink)

In questo articolo l’autore analizza il tema del muro statale a partire da una prospettiva interdisciplinare che connette ontologia, filosofia della tecnologia e filosofia politica. La tesi principale del saggio è che vi sia una differenza ontologica fra il muro e il confine su cui esso si inscrive. Dopo una breve discussione di alcune note teorie ontologiche, l’autore argomenta a favore della tesi per cui il muro non sia un oggetto sociale, bensì un artefatto. Più specificamente, il muro è un (...) “artefatto politico”, poiché è uno strumento che inscrive materialmente nello spazio una complessa relazione di potere. Al fine di concettualizzare l’emergente razionalità politica globale, gli studiosi francesi Florine Ballif e Stéphane Rosière hanno coniato un nuovo termine: teicopolitica. Il termine deriva dal greco teichos, che letteralmente significa “il muro della polis”. La teicopolitica, dunque, indica la politica di costruzione di muri, nella maggior parte dei casi per scopi securitari. Il saggio affronta alcuni aspetti della teicopolitica da un punto di vista filosofico. Nella prima parte del saggio, l’autore critica l’idea postmoderna di uno spazio globale fluido e virtuale, e la relativa idea di una consumazione storica e politica delle categorie moderne (Stato, sovranità, territorio); nella seconda parte, analizza approfonditamente la differenza ontologica fra muro e confini, nonché alcuni aspetti fenomenologici che vi si collegano; nella terza parte, mostra come e perché un muro studiato in quanto dispositivo implichi il riconoscimento di differenti forme di potere (sovrano, disciplinare, governamentale); nell’ultima parte, sostiene che il tema del muro statale debba essere affrontato attraverso quella che può essere definita una “ontologia politica degli artefatti”.

Fictionalism in ontology is a mixed bag. Here I focus on three main variants – which I label after the names of Pascal, Berkeley, and Hume – and consider their relative strengths and weaknesses. The first variant is just a version of the epistemic Wager, applied across the board. The second variant builds instead on the fact that ordinary language is not ontologically transparent; we speak with the vulgar, but deep down we think with the learned. Finally, on the Humean (...) variant it’s the structure of the ontological inventory, not its content, that may turn out to involve fictional elements. That is, for the Humean the fiction lies, not in the reality of common-sense ontology, but in the laws – of unity, identity, causation, etc. – in terms of which we articulate our experience of that reality. In the end, this is the kind of fictionalism that I find most interesting, sensible, and tenable. And I argue that it is even compatible with the sort of “naive” realism we have all come to appreciate in the work of Paolo Bozzi, to whom the paper is dedicated. (shrink)

We think of a boundary whenever we think of an entity demarcated from its surroundings. There is a boundary (a line) separating Maryland and Pennsylvania. There is a boundary (a circle) isolating the interior of a disc from its exterior. There is a boundary (a surface) enclosing the bulk of this apple. Sometimes the exact location of a boundary is unclear or otherwise controversial (as when you try to trace out the margins of Mount Everest, or even the boundary of (...) your own body). Sometimes the boundary lies skew to any physical discontinuity or qualitative differentiation (as with the border of Wyoming, or the boundary between the upper and lower halves of a homogeneous sphere). But whether sharp or blurry, natural or artificial, for every object there appears to be a boundary that marks it off from the rest of the world. Events, too, have boundaries — at least temporal boundaries. Our lives are bounded by our births and by our deaths; the soccer game began at 3pm sharp and ended with the referee's final whistle at 4:45pm. It is sometimes suggested that even abstract entities, such as concepts or sets, have boundaries of their own, and Wittgenstein could emphatically proclaim that the boundaries of our language are the boundaries of our world. Whether all this boundary talk is coherent, however, and whether it reflects the structure of the world or simply the organizing activity of our mind, are matters of deep philosophical controversy.

According to mainstream linguistic phonetics, speech can be modeled as a string of discrete sound segments or “phones” drawn from a universal phonetic inventory. Recent work has argued that a mature phonetics should refrain from theorizing about speech and speech processing using sound segments, and that the phone concept should be eliminated from linguistic theory. The paper lays out the tenets of the phone methodology and evaluates its prospects in light of the eliminativist arguments. I claim that the eliminativist arguments (...) fail to show that the phone concept should be eliminated from linguistic theory. (shrink)

The concept of nature in Western thought has been informed by the assumption of a categorical distinction between natural and artificial entities, which goes back to John Stuart Mill or even Aristotle. Such a way of articulating the natural/artificial distinction has proven unfit for conservation purposes mainly because of the extent and the pervasiveness of human activities that would leave no nature left to be conserved, and alternative views have been advanced. In this contribution, after arguing for the importance of (...) the concept of naturalness as a guide for conservation, I will try to provide an account of the natural/artificial distinction suited to contemporary conservation framing. Focusing on a particular kind of objects that I suggest to name “environmental objects”, I propose and defend the view of “naturalness as independence” according to which the more or less an environmental object's identity conditions and survival depend on human intervention, the more or less that object is artificial or natural, respectively. According to this view, conserving environmental objects will equate to maintaining or improving their naturalness or even originating artificial objects that may become new natural objects. This view has the advantage, on the one hand, of providing a rationale for a distinction which is not only part of how people think, but also pervasive in conservation practices and policies and, on the other hand, of accounting for the global pervasiveness of human intervention in the so-called natural world.

Global metaphysical antirealism (or “antirealism”) is often thought to entail that the identity of each and every concrete entity in our world ultimately depends on us—on our adoption of certain social and linguistic conventions, for instance, or on our use of certain conceptual schemes. Drawing on the middle‐period works of Maurice Merleau‐Ponty, I contend that metaphysical antirealism entails nothing of the sort. For Merleau‐Ponty, I argue, entities do not ultimately owe their identities to us, even though—as he puts it—their “articulations (...) are the very ones of our existence.” Once this is recognised, I maintain, certain interpretations of phenomenology are revealed to be caricatures and certain general objections to antirealism lose their force.

Este artículo aborda un estudio metafísico sobre límites en la discusión sobre composición material. Según la tesis nihilista, dos o más objetos nunca componen otro objeto. Los objetos materiales ordinarios y sus límites (superficies) serían entidades fiat, mientras que los objetos simples (sin partes) y sus límites precisos son los únicos componentes bona fide del mundo. Sin embargo, si hay razones para postular la existencia de un límite bona fide que separa una colección de objetos de sus alrededores espaciales, entonces (...) tenemos razones para postular también la existencia de un objeto compuesto bona fide. Si existe un límite, dada su dependencia ontológica, debe existir un objeto al cual pertenece. La emergencia de un límite de un objeto material tridimensional instancia propiedades irreductibles a las propiedades de alguna de sus partes. No obstante, una vez que los límites son introducidos en el mundo, la presencia de vaguedad ontológica en términos modales resulta inevitable. (shrink)
