Even though the talk of causal bases is commonplace in traditional and contemporary discussions about dispositions, the concept of causal bases has never been systematically investigated. This paper aims to fill this gap by developing the causal-grounding account. This account takes two roles as definitory for causal bases. First, causal bases are possible causes of disposition manifestations. Second, causal bases are metaphysical grounds of disposition instantiations. In this paper, we show that the causal-grounding account (CGA) achieves crucial distinctions (for example (...) between causal bases and manifestation conditions), captures relevant traditional features of causal bases, and can be invoked to support the causal efficacy of disposition instantiations. At the same time, CGA does not require that causal bases have to be categorical or intrinsic. This, in turn, allows us to remain neutral concerning fundamental properties, the existence of dispositional or extrinsic causal bases, multi-track dispositions, and the reducibility of dispositions. This neutrality grants the suitability of our account for different philosophical projects and discussions. (shrink)

According to power theorists, properties are powers—i.e. they necessarily confer on their bearers certain dispositions. Although the power theory is increasingly gaining popularity, a vast majority of analytic metaphysicians still favors what I call ‘the nomic theory’—i.e. the view according to which what dispositions a property confers on its bearers is contingent on what the laws of nature happen to be. This paper argues that the nomic theory is inconsistent, for, if it were correct, then properties would not confer any (...) dispositions on their bearers—they would only appear to do so (just like how, in cases of mimicking, objects do not really have the relevant dispositions, they merely appear to have them). If my arguments are sound, then the nomic theory is incoherent and ultimately collapses into what I call ‘neo-occasionalism’ and powers turns out to be the only available option for those who believe that properties genuinely confer dispositions on their bearers.

The Simple Counterfactual Analysis (SCA) was once considered the most promising analysis of disposition ascriptions. According to SCA, disposition ascriptions are to be analyzed in terms of counterfactual conditionals. In the last few decades, however, SCA has become the target of a battery of counterexamples. In all counterexamples, something seems to be interfering with a certain object’s having or not having a certain disposition thus making the truth-values of the disposition ascription and of its associated counterfactual come apart. Intuitively, however, (...) it would seem that, if all interferences were absent, the disposition ascription and its associated conditional would have the same truth-value. Although this idea may seem obvious, it is far from obvious how to implement it. In fact, it has become widely assumed that the content of qualifying ceteris paribus clauses (such as ‘if all interferences were absent’) cannot be specified in a clear and non-circular manner. In this paper, I will argue that this assumption is wrong. I will develop an analysis of disposition ascriptions, the Interference-Free Counterfactual Analysis, which relies on a clear and non-circular definition of the notion of interference and avoids the standard counterexamples to SCA while vindicating the intuition that disposition ascriptions and counterfactual conditionals are intimately related. (Please note that an erratum has been issued for the published version of this paper. It is recommended to read the self-archived version of the paper.). (shrink)

The notion of affordance remains elusive, notwithstanding its importance for the representation of agency, cognition, and behaviors. This paper lays down a foundation for an ontology of affordances by elaborating the idea of “core affordance” which would serve as a common ground for explaining existing diverse conceptions of affordances and their interrelationships. For this purpose, it analyzes M. T. Turvey’s dispositional theory of affordances in light of a formal ontology of dispositions. Consequently, two kinds of so-called “core affordances” are proposed: (...) specific and general ones. Inspired directly by Turvey’s original account, a specific core affordance is intimately connected to a specific agent, as it is reciprocal with a counterpart effectivity (which is a disposition) of this agent within the agent-environment system. On the opposite, a general core affordance does not depend on individual agents; rather, its realization involves an action by an instance of a determinate class of agents. The utility of such core affordances is illustrated by examining how they can be leveraged to formalize other major accounts of affordances. Additionally, it is briefly outlined how core affordances can be employed to analyze three notions that are closely allied with affordances: the environment, image schemas, and intentions. (shrink)

I investigate the intrinsic/extrinsic nature of stemness in muscle stem cells (MSC) by relying on recent research on quiescence, with the aim of shedding light on the nature of dispositions and deriving some consequences about stem cells. First, I argue why the study of quiescence is the best available way to establish any claim about the intrinsicness/extrinsicness of stemness at least is some stem cells. Drawing on that, I argue that MSC’s stem capacities result from the combination of intrinsic cues (...) plus extrinsic factors from the stem cell niche, making stemness an extrinsic disposition in MSC. Importantly, it is shown that the niche allows the instantiation of stemness in MSC by acting as a masker of its manifestation. This shows that stemness is, at least in MSC, what I call an extrinsically structurally masked disposition (SMD); that is, a disposition whose instantiation requires, as a condition of possibility, the interaction between the bearer and a masker. Finally, I conclude by suggesting some potential consequences of this observation for the philosophical study of dispositions and for stem cell research. (shrink)
