The addiction literature is fraught with conceptual confusions, stalled debates, and an unfortunate lack of clear and careful attempts to delineate the phenomenon of addiction in a way that might lead to consensus. My dissertation has two overarching aims, one metaphysical and one practical. -/- The first aim is to defend an account of addiction as the systematic disposition to fail to control one’s desires to engage in certain types of behaviors. I defend the inclusion of desires and impaired control (...) in the definition, and I flesh out the notion of systematicity central to my dispositionalist framework. I engage the so-called ‘disease vs. choice’ debate, criticizing its presupposition that we are dealing here with a dichotomy and arguing that the movement towards a middle ground is the right track to take. I explain how the dispositionalist account can capture this middle ground and how it serves to expand upon existing views, in particular by filling in the metaphysical details. -/- The second aim is to show how the account I defend can help to unify the extant views and disciplinary perspectives in the literature. Both the dispositionalist aspect of my framework and the methodology adopted (applied ontology and systematic metaphysics) can move the literature towards both substantive and methodological unification. This will help to clear up conceptual confusions, resolve (or sometimes dissolve) apparently intractable disputes, situate different research perspectives with respect to each other, facilitate interdisciplinary dialogue, and help to frame important questions about addiction. Finally, I offer the beginnings of an ontology of addiction, which will provide a terminologically well-structured guide to the addiction literature in a way that will facilitate more effective and efficient communication and data management across disciplines.

In taking properties to have powerful or dispositional essences, dispositionalism is primed to provide an account of causation. This paper lays out a challenge confronting the dispositionalist’s ability to account for how powers causally interact with one another so as to bring about collective results. The challenge, here labeled the “interaction gap,” is raised for two competing kinds of approaches to dispositional interaction: contribution combinationist and mutual manifestationist. After carefully highlighting and testing potential resources for closing the interaction gap, it (...) is concluded that the mutual manifestationist approach holds a significant advantage. In turn, the importance of the interaction gap itself is highlighted. While powers prime an ontology to yield an account of causation, how far that account can actually go depends on the metaphysical details of one’s view of powers and their causal interaction.

_ Source: _Page Count 20 Tugby and Yates have recently argued that immanent realism is incompatible with the existence of intrinsic but relationally constituted genuine dispositional properties. The success of Tugby’s and Yates’ arguments depends either on a strong or on a weak assumption about the interworld identity of dispositional properties. In this paper, the author evaluates the strength of the arguments in question under those two assumptions. He also offers an alternative metaphysical picture for the fundamental dispositional properties which (...) rejects these assumptions and, consequently, undermines the arguments themselves. (shrink)

Constitutivist accounts in metaethics explain the normative standards in a domain by appealing to the constitutive features of its members. The success of these accounts turns on whether they can explain the connection between normative standards and the nature of individuals they authoritatively govern. Many such explanations presuppose that any member of a norm-governed kind must minimally satisfy the norms governing its kind. I call this the Threshold Commitment, and argue that constitutivists should reject it. First, it requires constitutivists to (...) restrict the scope of their explanatory ambitions, because it is not plausibly true of social kinds. Second, despite the frequent reliance on physical artifacts in constitutivists’ illustrations of the Threshold Commitment, it counter-intuitively entails that physical artifacts can cease to exist without being physically destroyed. Third, it misconstrues the normative force of authoritative norms on very defective kind-members because it locates this force not in the norm, but in the threat of non-existence. Fortunately, constitutivism can be decoupled from the Threshold Commitment, and I close by sketching a promising alternative account. (shrink)

Dispositionalism about modality is the view that metaphysical modality is a matter of the dispositions possessed by actual objects. In a recent paper, David Yates has raised an important worry about the formal adequacy of dispositionalism. This paper responds to Yates’s worry by developing a reply that Yates discusses briefly but dismisses as ad hoc: an appeal to a ’plenitude of powers’ including such powers as the necessarily always manifested power for 2+2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} (...) \begin{document}$$2+2$$\end{document} to be 4. I argue that the reply is not ad hoc at all, by defending the metaphysics of dispositions that should underly it. I then argue, first, that a proper understanding of dispositions’ degrees provides us with an argument for such necessarily always manifested dispositions; second, that all the natural attempts to block that argument can be resisted without being ad hoc; and third, that pragmatic considerations explain our intuitive resistance to the ascription of necessarily always manifested dispositions. Dispositionalism can be formally adequate after all. (shrink)

This paper examines the need for static dispositions within the basic ontology of the powers view of properties. To lend some focus, Neil Williams’s well developed case for static dispositions is considered. While his arguments are not necessarily intended to address fundamental ontology, they still provide a useful starting point, a springboard for diving into the deeper metaphysical waters of the dispositionalist approach. Within that ontological context, this paper contends that Williams’s arguments fail to establish the need to posit static (...) dispositions, or at least any sort not already well appreciated by advocates of the powers view. The paper then proceeds to suggest an alternative motivation for positing static dispositions, the success of which depends greatly on which ontological approach to objects is paired with the powers view.

Faced with the conflict between our intuition that no two things ever share a place at a time and these counterexamples to it, philosophers usually try to find a happy medium between sticking with the original intuition and rejecting all of its counterexamples or giving up the whole intuition and accepting all the counterexamples. Some counterexamples might be rejected on conceptual grounds : one may deny for instance that absolute space is in the same place that the entities located therein (...) on the ground that absolute space is not itself located. One may also reject the distinct existence of some of the entities put forward in the examples : determinable properties might be nothing else than boolean combinations of determinate ones, spots on a screen may be just four dimensional worms whose passing through each other is a matter of part sharing rather than compenetration, etc. But as long as the conceivability of at least one counterexample is granted, the impenetrability intuition has to be weake- ned. To this end, one can weaken either the modal force of the impenetrability intuition or its scope. One may claim for instance that things are impenetrable in our world, but grant that the remaining counterexample refers to genuine metaphysical possibilities (although not natural ones). On the other hand, on may claim that the impenetrability intuition does not bear on every entity in the outside world, but only on some of them. Locke, famously, did not want to give up the metaphysical necessity of impenetrability, but agreed to restrict it to entities of the same kind.4 One other way to restrict the scope of the intuition of impenetrability is to claim that only independent entities (substances, or things proper) are impenetrable , or that only material entities are.

There are four main theories concerning the ultimate constitution of matter: atomism version 1, atomism version 2, the theory of gunk, and the theory of extended simples. These four theories are usually seen as diametrically opposed. Here I take a stab at ecumenism, and argue that atomism version 1 and the theory of extended simples can be reconciled and rendered compatible by reference to the reality of dispositions.

Work on dispositions focuses chiefly on dispositions that are manifested in dynamic causal processes. Williams, Neil. 2005. “Static and Dynamic Dispositions.” Synthese 146: 303–24 has argued that the focus on dynamic dispositions has been at the expense of a richer ontology of dispositions. He contends that we ought to distinguish between dynamic and static dispositions. The manifestation of a dynamic disposition involves some change in the world. The manifestation of a static disposition does not involve any change in the world. (...) In this paper, we concede that making a conceptual distinction between dynamic and static dispositions is useful and we allow that we can truthfully represent objects as manifesting static dispositions. However, we argue that the distinction is not ontologically deep. Rather, the truthmakers for our representations of static dispositions are actually dynamic dispositions to whose manifestations we may fail to be sensitive. (shrink)

A popular version of anti-Humeanism is one that views fundamental properties as being irreducibly dispositional in nature, and it is a view to which I am attracted. Proponents of this view typically object to Humean regularity theories of laws on the basis that they do not explain why our world is regular rather than chaotic from moment to moment. It is thought that, for this reason, Humeanism does not provide firm enough foundations for induction. However, in this paper I argue (...) that it is far from clear how these anti-Humeans can themselves explain this regularity. This is because it is far from clear how they can explain why the entities in our world do not change their dispositional properties arbitrarily over time. This is a neglected problem, which I call the retention problem. In an attempt to solve this problem, several naturalistic explanations of retention are explored. Unfortunately, none of these explanations is free of problems, showing that dispositional forms of anti-Humeanism may not have as many advantages as some have assumed where the problem of induction is concerned.

The paper defends a naturalistic version of modal actualism according to which what is metaphysically possible is determined by dispositions found in the actual world. We argue that there is just one world – this one – and that all genuine possibilities are grounded in the dispositions exemplified in it. This is the case whether or not those dispositions are manifested. As long as the possibility is one that would obtain were the relevant disposition manifested, it is a genuine possibility. (...) Furthermore, by starting from actual dispositional properties and branching out, we are able to countenance possibilities quite far removed from any state of affairs that happens to obtain, while still providing a natural and actual grounding of possibility. Stressing the importance of ontological considerations in any theory of possibility, it is argued that the account of possibility in terms of dispositional properties provides a more palatable ontology than those of its competitors. Coming at it from the other direction, the dispositional account of possibility also provides motivation for taking an ontology of dispositions more seriously. (shrink)

The aim of the paper is to give an ontologically informed account of disease that can aid in the construction of disease ontologies. The paper begins by distinguishing cases of diseases from what are purely structural abnormalities, referred to as ‘disorders’. The paper then presents a causal model apt for the understanding of disease that distinguishes diseases from both their causes and their potential effects. The analysis of disease defended treats disease in terms of distortions of standard cellular network processes, (...) where those distortions are incapable of self remedy and produce biologically disadvantageous symptoms.

In his landmark book on philosophical theology, Saving God: Religion After Idolatry, Mark Johnston develops a panentheistic metaphysic of the divine that he contends is compatible with ontological naturalism. On his view, God is the universe, but the ‘is’ is the ‘is’ of constitution, not identity. The universe and God are coinciding objects that share properties but have different essential modal properties and, hence, different persistence conditions. In this paper, I address the problem of accounting for what it is about (...) the organization or structure of the universe that makes it sufficient to constitute the Divine Mind. Specifically, I consider what kind of unity the universe exhibits in virtue of which it constitutes the Divine Mind. I consider how Johnston’s hylomorphic account of the unity of composite objects might be applied to provide a solution and offer an alternative that emends the Johnstonian proposal I present by exploiting a variant of a neo-Aristotelian ontology of causal powers that takes properties to be powerful qualities. On the framework I defend, we can understand the universe as a constellation of powers that displays the sort of unity sufficient to truthfully described it as a Divine Mind. The approach I recommend will, however, ultimately lend itself to a pantheistic metaphysic of the divine rather than Johnston’s preferred panentheism. (shrink)

Absences, i.e., agential omissions and forbearances, but also ‘natural’ negative states and events beyond the sphere of human agency, seem to be part and parcel of the real world. Yet, it is exactly the putative reality of absences that strikes many philosophers as utterly mysterious, if not entirely unintelligible. As a promising approach towards solving the problem of real absences, I wish to explore the idea that absences are latent potentialities. To this end, I shall investigate what potentialities are, what (...) kinds of potentiality exist, and what it means for a potentiality to remain latent. I will also discuss whether the framework of latent potentiality is able to meet the extensional constraints imposed on the theory of absences by our intuitions about the reach of negative acts and events, i.e., whether latent potentialities can account for all real absences.
