Properties seem to play an important role in causal relations. But philosophers disagree over whether or not properties play their causal or nomic roles essentially. Causal essentialists say that they do, while quidditists deny it. This article surveys these two views, as well as views that try to find a middle ground.

Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from (...) ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.

As Price (2009) famously mused, if a philosopher were to be magically transported, perhaps through means of time travel, from the 1950s to the modern day, they would indeed be shocked by the resurgence of metaphysics in the analytic tradition. Most of all, perhaps, they would be shocked by the popularity of power metaphysics. What a strange item to have in a philosopher’s curriculum, they might think: after all, didn’t David Hume claim that “[t]here are no ideas which can occur (...) in metaphysics more obscure and uncertain than those of power, force, energy, or necessary connection”? Indeed, much has changed since then. At the pain of using overly vague terminology, we can call “power metaphysics” the subdiscipline of metaphysics interested in the development and evaluation of a family of positions which we will refer to under the umbrella term of “dispositionalism”. According to dispositionalists, the world we inhabit is also populated by genuine and irreducible powers, dispositions, and capacities of objects. (shrink)

The bulk of the literature concerning the governing role of non-Humean laws has been concentrated on the alleged incapability of higher order nomic facts to determine the regularities in the behaviour of actual objects, the so-called Inference Problem. Most recently Ioannidis, Livanios and Psillos (2021) argue that an adequate solution to the Inference Problem requires an answer to the question of how nomic relations manage to ‘tell’ properties what to do. Ioannidis et al. dub the difficulty that all extant accounts (...) of governing laws face to give such an answer, the Governing Problem and introduce a Dualist Model, according to which the specific behaviour of things in the world is the outcome of both the thin powers things have to be subjected to laws, and certain nomic features of the world. The aim of this paper is to show that the most plausible form of the Dualist Model can provide the basis for a novel version of the Powerful Qualities View about properties. To this end it presents ways of developing two aspects of the Dualist Model. It defends the view that nomic relations must be relata-specific in order to play their theoretical role within the Model and provides arguments for the view that natural properties should have the minimum (compatible with the core tenets of the Model) modal strength.

The Identity Theory of properties (IDT) is an increasingly popular metaphysical view that aims to be a middle way between pure powerism and pure categoricalism. This paper’s goal is to highlight three major difficulties that IDT should address in order to be a plausible account of the nature of properties. First, although IDT needs a clear definition of the notion of qualitativity which is both adequate and compatible with the tenets of the theory, all the extant proposals fail to provide (...) such a definition. Second, the suggested definitions of qualitativity are characterised by a metaphysical ‘neutrality’ that threatens to trivialise the important metaphysical debate regarding the question whether properties confer by themselves dispositions on their bearers (and so they are inherently modal and active) or need the ‘assistance’ of laws of nature to do that. Finally, none of the extant alternative understandings of the core identity-claim of IDT can adequately meet the objection that the claim in question is unintelligible. (shrink)

In recent years, a new dispute has risen to prominence: the dispute between realists and anti-realists about causal powers. Albeit sometimes overlooked, the meta-ontological features of this “question of realism for powers” are quite peculiar. For friends and foes of causal powers have characterized their contrasting views in a variety of different ways; as existence claims, as semantic or truth-making claims, as fundamentality claims, as claims about the nature of certain properties. Not only does this multiplicity of interpretations make it (...) unclear what the genuine bone of contention is, if there is one; some of them appear to be mutually exclusive. Some light can be shed on this apparent yet widespread confusion by distinguishing three degrees of ontological involvement in dispositional truths; viz., three ways, of increasing robustness, to read ontological commitments from dispositional truths. Relatedly, by exploring the literature, and focusing on some selected examples of power realism and anti-realism, we can observe that power realists vastly disagree over the intrinsic nature ad make-up of dispositional properties. Such examples furthermore invite the thought that the question of realism for powers is best understood not as the debate around the existence of properties with a distinctive identity, but rather as a debate about metaphysical hierarchy. Finally, some anti-realists positions are indistinguishable from realist ones, using merely intensional resources: power realism is best appreciated by going hyperintensional. (shrink)

Discussions about dispositional and categorical properties have become commonplace in metaphysics. Unfortunately, dispositionality and categoricity are disputed notions: usual characterizations are piecemeal and not widely applicable, thus threatening to make agreements and disagreements on the matter merely verbal—and also making it arduous to map a logical space of positions about dispositional and categorical properties in which all parties can comfortably fit. This paper offers a prescription for this important difficulty, or at least an inkling thereof. This will be achieved by (...) comparing pairs of positions and exploring their background metaphysics to discover where alleged agreements and disagreements concerning dispositionality and categoricity really lie; more specifically, the Pure Powers view and the Powerful Qualities view will be under scrutiny. Over this background, the prescription functions by isolating a successful identity-based characterization of categoricity, while abandoning the correspondent identity-based characterization of dispositionality. On the contrary, according to this prescription a property is dispositional if and only if it is solely in virtue of possessing that property that its bearer is assigned a certain dispositional profile. A crucial consequence of this prescription is that, while supporters of the Pure Powers view often characterize their position as an essentialist one, the dispositionality of properties needn’t always be a matter of essence.
