In identifying intrinsic molecular chance and extrinsic adaptive pressures as the only causally relevant factors in the process of evolution, the theoretical perspective of the Modern Synthesis had a major impact on the perceived tenability of an ontology of dispositional properties. However, since the late 1970s, an increasing number of evolutionary biologists have challenged the descriptive and explanatory adequacy of this “chance alone, extrinsic only” understanding of evolutionary change. Because morphological studies of homology, convergence, and teratology have revealed (...) a space of possible forms and phylogenetic trajectories that is considerably more restricted than expected, evo-devo has focused on the causal contribution of intrinsic developmental processes to the course of evolution. Evo-devo’s investigation into the developmental structure of the modality of morphology – including both the possibility and impossibility of organismal form – has led to the utilisation of a number of dispositional concepts that emphasise the tendency of the evolutionary process to change along certain routes. In this sense, and in contrast to the perspective of the Modern Synthesis, evo-devo can be described as a “science of dispositions.” This chapter discusses the recent philosophical literature on dispositional properties in evo-devo, exploring debates about both the metaphysical and epistemological aspects of the central dispositional concepts utilised in contemporary evo-devo and addressing the epistemological question of how dispositional properties challenge existing explanatory models in evolutionary biology.

My interest in this chapter is to investigate this crossroad as applied to mental properties, considered powers. In particular, I scrutinize the possibility of taking the phenomenal property of feeling pain as a complex power or disposition. This possibility comes in handy in discussing panpsychism, the view that the ultimate elements of reality are phenomenal properties, which would ground physical properties as well.

This paper has two main aims. The first is to present a general approach for understanding “dispositional” and “categorical” properties; the second aim is to use this approach to criticize Russellian Monism. On the approach I suggest, what are usually thought of as “dispositional” and “categorical” properties are really just the extreme ends of a spectrum of options. The approach allows for a number of options between these extremes, and it is plausible, I suggest, that just (...) about everything of scientific interest falls in this middle ground. I argue that Russellian Monism depends for its plausibility on the unarticulated assumption that there are no properties in the middle ground. (shrink)

The article explains my third argument for panpsychism, based on disolving all properties, including dispositional physical properties like mass, energy, and force, into phenomenal properties. I thus reject a dual-property version of panpsychism. I seek to show, contrary to Paul Churchland, that the general panpsychist hypothesis has some explanatory value, and makes a cosmology consisting in comparative psychology possible. The mental life even of so-called physical particles in physics is hypothesized to help explain their behavior.

In this paper I examine the role of dispositional properties in the most frequently discussed interpretations of non-relativistic quantum mechanics. After offering some motivation for this project, I briefly characterize the distinction between non-dispositional and dispositional properties in the context of quantum mechanics by suggesting a necessary condition for dispositionality – namely contextuality – and, consequently, a sufficient condition for non-dispositionality, namely non-contextuality. Having made sure that the distinction is conceptually sound, I then analyze the (...) plausibility of the widespread, monistic ontological thesis about the reducibility of dispositional properties to categorical properties in the context of the philosophy of quantum mechanics. I conclude that with the exception of Bohmian mechanics, the other “minimally realist” views of quantum mechanics require essential dispositions, i.e., dispositions of a non-reducible kind. Interestingly, seen behind the lenses of dispositionalism, Bohr’s and Bohm’s interpretations of quantum mechanics are much closer than it is usually recognized, a fact that could teach us something about the way the quantum world is. (shrink)

After some suggestions about how to clarify the confused metaphysical distinctions between dispositional and non-dispositional or categorical properties, I review some of the main interpretations of QM in order to show that – with the relevant exception of Bohm’s minimalist interpretation – quantum ontology is irreducibly dispositional. Such an irreducible character of dispositions must be explained differently in different interpretations, but the reducibility of the contextual properties in the case of Bohmian mechanics is guaranteed by (...) the fact that the positions of particles play the role of the categorical basis, a role that in other interpretations cannot be filled by anything else. In Bohr’s and Everett-type interpretations, dispositionalism is instrumentalism in disguise. (shrink)

Dispostions, such as solubility, cannot be reduced to categorical properties, such as molecular structure, without some element of dipositionaity remaining. Democritus did not reduce all properties to the geometry of atoms - he had to retain the rigidity of the atoms, that is, their disposition not to change shape when a force is applied. So dispositions-not-to, like rigidity, cannot be eliminated. Neither can dispositions-to, like solubility.

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.

Dispositional properties are often referred to as ‘causal powers’, but what does dispositional causation amount to? Any viable theory must account for two fundamental aspects of the metaphysics of causation – the causal complexity and context sensitivity of causal interactions. The theory of mutual manifestations attempts to do so by locating the complexity and context sensitivity within the nature of dispositions themselves. But is this theory an acceptable first step towards a viable theory of dispositional causation? (...) This paper argues that the reconceptualization that the theory entails comes at too high a price, and is an unnecessary step in the wrong direction: these two central aspects concerning the metaphysics of causation can and should be accounted for in a dispositional account of causation without it. (shrink)

A dispositional property is a tendency, or potency, to manifest some characteristic behaviour in some appropriate context. The mainstream view in the twentieth century was that such properties are to be explained in terms of more fundamental non-dispositional properties, together with the laws of nature. In the last few decades, however, a rival view has become popular, according to which some properties are essentially dispositional in nature, and the laws of nature are to be (...) explained in terms of these fundamental dispositions. The supposed ability of fundamental dispositions to ground natural laws is one of the most attractive features of the dispositional essentialist position. In this paper, however, I cast doubt on the ability of dispositional essences to ground the laws of nature. In particular I argue that the dispositional essentialist position is not able to coherently respond—sympathetically or otherwise—to Cartwright's challenge that there are no true general laws of nature.

As we understand them, dispositions are relatively uncontroversial 'predicatory' properties had by objects disposed in certain ways. By contrast, powers are hypothetical 'ontic' properties posited in order to explain dispositional behaviour. Chapter 1 outlines this distinction in more detail. Chapter 2 offers a summary of the issues surrounding analysis of dispositions and various strategies in contemporary literature to address them, including one of our own. Chapter 3 describes some of the important questions facing the metaphysics of powers (...) including why they're worth positing, and how they might metaphysically explain laws of nature and modality. (shrink)

This paper develops two ideas with respect to dispositional properties: (1) Adapting a suggestion of Sungho Choi, it appears the conceptual distinction between dispositional and categorical properties can be drawn in terms of susceptibility to finks and antidotes. Dispositional, but not categorical properties, are not susceptible to intrinsic finks, nor are they remediable by intrinsic antidotes. (2) If correct, this suggests the possibility that some dispositions—those which lack any causal basis—may be insusceptible to any (...) fink or antidote. Since finks and antidotes are a major obstacle to a conditional analysis of dispositions, these dispositions that are unfinkable may be successfully analysed by the conditional analysis of dispositions. This result is of importance for those who think that the fundamental properties might be dispositions which lack any distinct causal basis, because it suggests that these properties, if they exist, can be analysed by simple conditionals and that they will not be subject to ceteris paribus laws. (shrink)

According to the proponents of Developmental Systems Theory and the Causal Parity Thesis, the privileging of the genome as “first among equals” with respect to the development of phenotypic traits is more a reflection of our own heuristic prejudice than of ontology - the underlying causal structures responsible for that specified development no more single out the genome as primary than they do other broadly “environmental” factors. Parting with the methodology of the popular responses to the Thesis, this paper offers (...) a novel criterion for ‘causal primacy’, one that is grounded in the ontology of the unique causal role of dispositional properties. This paper argues that, if the genome is conceptualised as realising dispositional properties that are “directed toward” phenotypic traits, the parity of ‘causal roles’ between genetic and extra-genetic factors is no longer apparent, and further, that the causal primacy of the genome is both plausible and defensible.

Ordinary language and scientific discourse are filled with linguistic expressions for dispositional properties such as “soluble,” “elastic,” “reliable,” and “humorous.” We characterize objects in all domains – physical objects as well as human persons – with the help of dispositional expressions. Hence, the concept of a disposition has historically and systematically played a central role in different areas of philosophy ranging from metaphysics to ethics. The contributions of this volume analyze the ancient foundations of the discussion about (...) disposition, examine the problem of disposition within the context of the foundation of modern science, and analyze this dispute up to the 20th century. Furthermore, articles explore the contemporary theories of dispositions. (shrink)

Dispositional Essentialism is a unified anti-Humean account of the metaphysics of low-level physical properties and laws of nature. In this paper, I articulate the view that I label Canonical Dispositional Essentialism, which comprises a structuralist metaphysics of properties and an account of laws as relations in the property structure. I then present an alternative anti-Humean account of properties and laws. This account rejects CDE’s structuralist metaphysics of properties in favour of a view of (...) class='Hi'>properties as qualitative grounds of dispositions and it rejects CDE’s view of laws as relations in favour of a view of laws as features of an efficient description of possible property distributions. I then defend this view over CDE on the grounds that it can overcome an explanatory shortcoming of CDE and that it achieves a level of continuity with science that CDE fails to achieve. The upshot of this paper is a significant narrowing of the range of possibilities in which the absolutely best unified account of laws and properties resides. (shrink)

Dispositions are modal properties. The standard conception of dispositions holds that each disposition is individuated by its stimulus condition(s) and its manifestation(s), and that their modality is best captured by some conditional construction that relates stimulus to manifestation as antecedent to consequent. I propose an alternative conception of dispositions: each disposition is individuated by its manifestation alone, and its modality is closest to that of possibility — a fragile vase, for instance, is one that can break easily. The view (...) is expounded in some detail and defended against the major objections. (shrink)

Metaphysics should follow science in postulating laws alongside properties. I defend this claim against the claim that natural properties conceived as powers make laws of nature redundant. Natural properties can be construed in a “thin” or a “thick” way. If one attributes a property in the thin sense to an object, this attribution does not conceptually determine which other properties the object possesses. The thin construal is underlying the scientific strategy for understanding nature piecemeal. Science explains (...) phenomena by cutting reality conceptually in properties attributed to space-time points, where these properties are conceived of independently of each other, to explore then, in a separate step, how the properties are related to each other; those determination relations between properties are laws. This is compatible with the thesis that laws are metaphysically necessary. According to the thick conception, a property contains all its dependency relations to other properties. The dependency relationships between properties (which appear as laws in the thin conception) are parts of the properties they relate. There are several reasons to resist the thick conception of properties. It makes simple properties “holistic”, in the sense that each property contains many other properties as parts. It cannot account for the fact that properties constrain each other’s identity; it can neither explain why natural properties are linked to a unique set of dispositions, nor why and how this set is structured nor why the truth-maker of many disposition attributions is relational although the disposition is grounded on a monadic property. (shrink)

This thesis proposes that key, competing theories of dispositions mistake and conflate how we identify, designate and talk about dispositions and dispositional terms for the nature of dispositions and the meaning of dispositional terms when they argue that: a) dispositions are extrinsic properties of their bearers (Boyle 1666) b) all properties are purely dispositional (Bird 2007) c) all properties are purely categorical (there are no dispositional properties) (Armstrong in AMP 1996) d) (...) class='Hi'>dispositional and categorical properties are separate and distinct properties (Prior, Pargetter and Jackson 1982). In so doing these theories make unwarranted and unsupported ontological conclusions about dispositions. The thesis traces the principal source of this confusion and conflation to a reliance on the counterfactual analysis of dispositions that wrongly encourages the conflation of a disposition (say fragility) with its manifestation (shattering). There is good reason to hold that the counterfactual analysis of dispositions is false — the truth of a counterfactual statement (such as “if x were dropped x would break”) is neither necessary nor sufficient for the truth of a dispositional ascription (such as “x is fragile”). (shrink)

This paper examines the idea that there might be natural kinds of causal processes, with characteristic diachronic structure, in much the same way that various chemical elements form natural kinds, with characteristic synchronic structure. This claim -- if compatible with empirical science -- has the potential to shed light on a metaphysics of essentially dispositional properties, championed by writers such as Bird and Ellis.

Abilities are in many ways central to what being an agent means, and they are appealed to in philosophical accounts of a great many different phenomena. It is often assumed that abilities are some kind of dispositional property, but it is rarely made explicit exactly which dispositional properties are our abilities. Two recent debates provide two different answers to that question: the new dispositionalism in the debate about free will, and virtue reliabilism in epistemology. This paper argues (...) that both answers fail as general accounts of abilities, and discusses the ramifications of this result. (shrink)

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. (shrink)

I will argue firstly that law-statements should be understood as attributing dispositional properties. Second, the dispositions I am talking about should not be conceived as causes of their manifestations but rather as contributors to the behavior of compound systems. And finally I will defend the claim that dispositional properties cannot be reduced in any straightforward sense to non-dispositional (categorical) properties and that they need no categorical bases in the first place.

Dispositional essentialists argue that physical properties have their causal roles essentially. This is typically taken to mean that physical properties are identical to dispositions. I argue that this is untenable, and that we must instead say that properties bestow dispositions. I explore what it is for a property to have such a role essentially. Dispositional essentialists argue for their view by citing certain epistemological and metaphysical implications, and I appeal to these implications to place desiderata (...) on the concept of essence involved. I argue that the traditional modal theory of essence meets these desiderata, but that the resulting theory wrongly implies that certain dispositions essential to mass are essential to charge, thereby offering a new argument against modal theories of essence. I argue that dispositional essentialism requires a primitive notion of essence, and develop a primitivist theory based on Kit Fine's views. I show that the primitivist theory has all the virtues of the modal alternative, and none of the vices. I develop a novel way of thinking about the relationship between properties, laws and dispositions, and argue that it has distinct advantages over standard dispositional essentialist formulations.

This article gives a general overview of recent metaphysical work on dispositional properties and causal relations. It serves as an introduction to the edited volume, Dispositions and Causes.

This book is about the nature of dispositional properties, or dispositions. It is hard to give an uncontroversial definition of the notion of a disposition, since its very definition is one of the matters under dispute. But we can make a start with the following preliminary definition: a disposition is a property (such as solubility, fragility, elasticity) whose instantiation entails that the thing which has the property would change, or bring about some change, under certain conditions. For instance, (...) to say that some object is soluble is to say that it would dissolve if put in water; to say that something is fragile is to say that it would break if (for instance) dropped in suitable circumstances; to say that something is elastic is to say that it would stretch when pulled. The fragility (solubility, elasticity) is a disposition; the breaking (dissolving, stretching) is the manifestation of the disposition. (shrink)

In this paper I argue that bodily pain, as a phenomenal property, is an essentially and substantial dispositional property. To this end, I maintain that this property is individuated by its phenomenal roles, which can be internal -individuating the property per se- and external -determining further phenomenal or physical properties or states. I then argue that this individuation allows phenomenal roles to be organized in a necessarily asymmetrical net, thereby overcoming the circularity objection to dispositionalism. Finally, I provide (...) reasons to argue that these roles satisfy modal fixity, as posited by Bird, and are not fundamental properties, contra Chalmers’ panpsychism. Thus, bodily pain can be considered a substantial dispositional property entrenched in non-fundamental laws of nature. (shrink)

In this paper, I argue in favor of necessitarianism, the view that dispositions, when stimulated, necessitate their manifestations. After introducing and clarifying what necessitarianism does and does not amount to, I provide reasons to support the view that dispositions once stimulated necessitate their manifestations according to the stimulating conditions and the relevant properties at stake. In this framework, I will propose a principle of causal relevance and some conditions for the possibility of interference that allow us to avoid the (...) use of ceteris paribus clauses. I then defend necessitarianism from recent attacks raised by, among others, Mumford and Anjum, noting that the antecedent strengthening test is a test for causal relevance that raises no difficulties for necessitarianism.

This Thesis engages with contemporary philosophical controversies about the nature of dispositional properties or powers and the relationship they have to their non-dispositional counterparts. The focus concerns fundamentality. In particular, I seek to answer the question, ‘What fundamental properties suffice to account for the manifest world?’ The answer I defend is that fundamental categorical properties need not be invoked in order to derive a viable explanation for the manifest world. My stance is a field-theoretic view (...) which describes the world as a single system comprised of pure power, and involves the further contention that ‘pure power’ should not be interpreted as ‘purely dispositional’, if dispositionality means potentiality, possibility or otherwise unmanifested power or ability bestowed upon some bearer. The theoretical positions examined include David Armstrong’s Categoricalism, Sydney Shoemaker’s Causal Theory of Properties, Brian Ellis’s New Essentialism, Ullin Place’s Conceptualism, Charles Martin’s and John Heil’s Identity Theory of Properties and Rom Harré’s Theory of Causal Powers. The central concern of this Thesis is to examine reasons for holding a pure-power theory, and to defend such a stance. This involves two tasks. The first requires explaining what plays the substance role in a pure-power world. This Thesis argues that fundamental power, although not categorical, can be considered ontologically-robust and thus able to fulfil the substance role. A second task—answering the challenge put forward by Richard Swinburne and thereafter replicated in various neo-Swinburne arguments—concerns how the manifestly qualitative world can be explained starting from a pure-power base. The Light-like Network Account is put forward in an attempt to show how the manifest world can be derived from fundamental pure power. (shrink)

In the realm of the philosophy of sounds and auditory experience there is an ongoing discussion concerned with the nature of sounds. One of the contestant views within this ontology of sound is that of the Property View, which holds that sounds are properties of the sounding objects. A way of developing this view is through the idea of dispositionalism, namely, by sustaining the theory according to which sounds are dispositional properties (Pasnau 1999; Kulvicki 2008; Roberts 2017). (...) That portrayal, however, is not sufficient, as it has not inquired the metaphysical debates about dispositions beyond the conditional analysis. In this paper, I try to advance this view by including recent developments (for instance Bird 2007; Vetter 2015) in the field of dispositionalism and I analyse whether this new version can sort out known and new objections to Property View.

It is common in psychiatry and other sciences to describe an individual or a type of individual in terms of its disposition to manifest specific effects in a particular range of circumstances. According to one understanding, dispositions are statistical regularities of an individual or type of individual in specific circumstances. According to another understanding, dispositions are properties of individuals in virtue of which such regularities hold. This entry considers a number of ways of making each of these senses of (...) disposition more precise while discussing a number of dangers lurking in careless use of the concept of a disposition.

My aim in this paper is to consider a series of arguments against Dispositional Moral Realism and argue that these objections are unsuccessful. I will consider arguments that try to either establish a dis-analogy between moral properties and secondary qualities or try to show that a dispositional account of moral properties fails to account for what a defensible species of moral realism must account for. I also consider criticisms from Simon Blackburn, who argues that there could (...) not be a corresponding perceptual faculty for moral properties, and David Enoch, who argues that Dispositional Moral Realism does not most plausibly explain the difference between moral disagreements and disagreements of mere preference. Finally, I examine a novel criticism concerning the relationship between the diverse variety of moral properties and the range of our normative affective attitudes, arguing that the view has no problem accounting for this diversity.

Bird reveals an important problem at the heart of Armstrong’s theory of laws of nature: to explain how a law necessitates its corresponding regularity, Armstrong is committed to a vicious regress. In his very brief response, Armstrong gestures towards an argument that, as he admits, is more of a “speculation.” Later, Barker and Smart argue that a very similar problem threatens Bird’s dispositional monist theory of laws of nature and he is committed to a similar vicious regress. In this (...) paper, first, I construct Armstrong’s would-be argument in response to Bird. Second, I argue that his response makes his account of laws and natural properties incompatible with science. Finally, I argue that Armstrong’s strategy to address Bird’s criticism can be used, quite ironically, to defuse Barker and Smart’s argument against Bird. (shrink)

Bird argues that Armstrong’s necessitarian conception of physical modality and laws of nature generates a vicious regress with respect to necessitation. We show that precisely the same regress afflicts Bird’s dispositional-monist theory, and indeed, related views, such as that of Mumford & Anjum. We argue that dispositional monism is basically Armstrongian necessitarianism modified to allow for a thesis about property identity.

Suppose that X and Y can’t possibly exist apart in reality; then—by definition—there’s no real distinction between them, only a conceptual distinction. There’s a conceptual distinction between a rectilinear figure’s triangularity and its trilaterality, for example, but no real distinction. In fundamental metaphysics there is no real distinction between an object’s categorical properties and its dispositional properties. So too there is no real distinction between an object and its properties. And in fundamental metaphysics, for X and (...) Y to be such that there is no real distinction between them is for them to be identical. (shrink)

One of the traditional desiderata for a metaphysical theory of laws of nature is that it be able to explain natural regularities. Some philosophers have postulated governing laws to fill this explanatory role. Recently, however, many have attempted to explain natural regularities without appealing to governing laws. Suppose that some fundamental properties are bare dispositions. In virtue of their dispositional nature, these properties must be (or are likely to be) distributed in regular patterns. Thus it would appear (...) that an ontology including bare dispositions can dispense with governing laws of nature. I believe that there is a problem with this line of reasoning. In this essay, I’ll argue that governing laws are indispensable for the explanation of a special sort of natural regularity: those holding among categorical properties (or, as I’ll call them, categorical regularities). This has the potential to be a serious objection to the denial of governing laws, since there may be good reasons to believe that observed regularities are categorical regularities. (shrink)

Would it be possible to have an alternative to the physicalist world-view? If any type of dualism is not an option, I am tempted to consider an integrational world view, which was first claimed by Confucius under the notion of cheng. I would propose an integrational thesis that cheng of an entity is a power to realize the embedded objective of it in the context where it interacts with all others. The notion of compassion may be said to be both (...) dispositional and mental. Then, this notion is one candidate to shed lights on the integrational thesis. The thesis doesn't exclude roles the causal notion has to play in the integrational system. Rather it allows the causal notion in its proper place, not having to exclude other relational notions in the system. What it denies is that the causal relation is all there is among what is there. The notion of compassion is essentialist in two senses. The first is the sense in which Mencius said that compassion is necessary for one to be a human. The second is the sense that compassion is an essentialist disposition. "Compassion" does neither refer to a mental state nor reflect a human relation, but it denotes an abstract property, or a theoretical notion, which can be singled out by a Ramsey sentence. There are many challenges for the integrational thesis to meet. Some of them are how the integrational thesis could allow an essentialism of a kind?, Is there a way for the integrational view of language to meet the requirements of modal semantics?, and so on. The present paper may not able to explain all of these questions but it will try to suggest how to approach toward the task. (shrink)

This paper argues for a realist position in the metaphysics of aesthetic properties. Realist positions about aesthetic properties are few and far between, though sometimes developed by analogy to realism about colours. By contrast, my position is based on a disanalogy between aesthetic properties and colours. Unlike colours, aesthetic properties are perceived as relatively unsteady properties: as powers that objects have to cause a certain experience in the observer. Following on from this observation, I develop (...) a realist account of aesthetic properties as causally efficient powers, analogous to properties like fragility or poisonousness. To show how such a view can be made ontologically respectable, I draw on recent ‘dispositionalist’ accounts of powers in philosophical metaphysics. I then offer two arguments in favour of this view. First, the view matches the phenomenology of aesthetic judgement. Second, the view offers an explanation of how it is that critics can demand agreement with their aesthetic judgements. (shrink)

Dispositional essentialists are typically committed to two claims: that properties are individuated by their causal role (‘causal structuralism’), and that natural necessity is to be explained by appeal to these causal roles (‘dispositional actualism’). I argue that these two claims cannot be simultaneously maintained; and that the correct response is to deny dispositional actualism. Causal structuralism remains an attractive position, but doesn’t in fact provide much support for dispositional essentialism.

McKitrick (2003) proposes that an object has a disposition if and only if there are a manifestation, the circumstances of the manifestation, a counterfactual true of the object, and an overtly dispositional locution referring to the disposition. A disposition is extrinsic if and only if an object has it, but a perfect duplicate of the object might not have it. I present an alternative definition that an object has a disposition if and only if a counterfactual is true of (...) the object that under a certain condition, it would interact with another object in a certain manner. There are three reasons for thinking that my definition is better than her definition. 1. Ockham’s razor favors my definition over McKitrick’s definition. My definition is consistent, while her definition is not, with Lewis’s and her definitions of intrinsic and extrinsic properties. 3. My definition goes well, while her definition does not, with our intuition that an object has a disposition even in a possible world where there is nothing but that object. (shrink)

Evolutionary developmental biology represents a paradigm shift in the understanding of the ontogenesis and evolutionary progression of the denizens of the natural world. Given the empirical successes of the evo-devo framework, and its now widespread acceptance, a timely and important task for the philosophy of biology is to critically discern the ontological commitments of that framework and assess whether and to what extent our current metaphysical models are able to accommodate them. In this paper, I argue that one particular model (...) is a natural fit: an ontology of dispositional properties coherently and adequately captures the crucial casual-cum-explanatory role that the fundamental elements of evo-devo play within that framework. (shrink)

In this paper I will defend the view that, according to Locke, secondary qualities are dispositions to produce sensations in us. Although this view is widely attributed to Locke, this interpretation needs defending for two reasons. First, commentators often assume that secondary qualities are dispositional properties because Locke calls them “powers” to produce sensations. However, primary qualities are also powers, so the powers locution is insufficient grounds for justifying the dispositionalist interpretation. Second, if secondary qualities are dispositional (...) properties then objects would retain secondary qualities while not being observed, but Locke says that colors “vanish” in the dark. Some commentators use this as evidence that Locke rejects the dispositionalist view of secondary qualities, and even those that are sympathetic to the traditional interpretation find these comments to be problematic. By contrast, I argue that even in these supposedly damning passages Locke shows an unwavering commitment to the view that the powers to produce sensations in us, i.e., the secondary qualities, remain in objects even when they are not being perceived. Thus the arguments against the traditional interpretation are unpersuasive, and we should conclude that Locke does indeed hold that secondary qualities are dispositions to cause sensations in us.

The paper looks at the semantics and ontology of dispositions in the light of recent work on the subject. Objections to the simple conditionals apparently entailed by disposition statements are met by replacing them with so-called 'reduction sentences' and some implications of this are explored. The usual distinction between categorical and dispositional properties is criticised and the relation between dispositions and their bases examined. Applying this discussion to two typical cases leads to the conclusion that fragility is not (...) a real property and that, while both temperature and its bases are, this does not generate any problem of overdetermination.

This paper delves into the nature of intellectual property rights in aesthetic creations, particularly works of visual art and literary works. The discussion focuses on copyrights interests, but there are also implications for trademark and patent rights. The argument assumes a fairly conventional definition of "property," namely, the set of legal relations between the owner and all other persons relating to the use, enjoyment and disposition of a tangible thing. The problem with such a definition as applied to aesthetic creations (...) is that no ordinary tangible thing necessarily embodies a creation which can exist in multiple copies, so the paper takes the transcendent view that the tangible thing subject to legal relations is the entire terra firma or material universe being shaped in the image, sounds or words of the aesthetic creation. Therefore, the paradigm suggested for intellectual property is a monopoly on shaping the entire physical universe, thus the Worldmaking concept. It then follows that intellectual property in an aesthetic creation enables the owner to stop plagiarists from using any part of the material world to recreate in the audience the imaginative experiences first created by the protected work.

This paper will investigate the basic question of the nature of perception, as theoretically approached from a purely naturalistic standpoint. An adequate theory must not only have clear application to a world full of pre-existing biological examples of perception of all kinds, from unicellular perception to conscious human perception, but it must also satisfy a series of theoretical or philosophical constraints, as enumerated and discussed in Section 1 below. A perceptual theory invoking _reflexive dispositions_--that is, dispositions directed toward the very (...) same worldly perceived objects or properties that caused them--will be defended as one legitimate such naturalistic theory.

Causal structuralism is the view that, for each natural, non-mathematical, non-Cambridge property, there is a causal profile that exhausts its individual essence. On this view, having a property’s causal profile is both necessary and sufficient for being that property. It is generally contrasted with the Humean or quidditistic view of properties, which states that having a property’s causal profile is neither necessary nor sufficient for being that property, and with the double-aspect view, which states that causal profile is necessary (...) but not sufficient. Shoemaker’s (1998) and Hawthorne’s (2001) arguments in favor of causal structuralism primarily focus on problematic consequences of the other two views. I argue, however, that causation does not provide an appropriate framework within which to characterize all physical properties for two main reasons. First, there are physical properties that do not have causal profiles and properties whose causal profiles do not exhaust their essences. Second, there is no unified notion of causation across the sciences. After distinguishing between the causal and the nomological, I suggest that what is needed is a structuralist view of properties that is not merely causal but that incorporates a physical property’s higher-order mathematical and nomological properties into its identity conditions. Such a view retains the naturalistic motivations for causal structuralism while avoiding the problems it faces. (shrink)

No one influenced and shaped our thinking about dispositions and causal properties more than Aristotle. What he wrote about power (dynamis), nature (physis) and habit (hexis) has been read, systematised and criticised again and again during the history of philosophy. In this chapter I sketch Aristotle's thoughts about dispositions and argue that his theory can still be regarded as a good one.

ABSTRACT. This essay addresses the interpretation of Descartes’ understanding of the mind-body relationship as a substantial union in light of a statement he makes in the Passions de l’âme regarding the role of the blood and vital heat. Here, it seems Descartes cites these corporeal properties as the essential dispositions responsible for accommodating the soul into the human fetus. I argue that this statement should be read in the context of certain medical texts with which Descartes was familiar, namely (...) those of Jean Fernel and William Harvey. Reviewing Fernel’s comments on substantial union, one finds that the soul joins the body on the basis of a celestial spirit that not only bears the vital heat, it also directs the generation of the body. Similar to Harvey, Descartes locates these properties in the blood itself, although, in contrast to Harvey, Descartes reduces these processes to matter and motion. Finally, I highlight the role this heat plays in Descartes’ embryological writing, contrasting it with that of Fernel. I conclude that although Descartes makes various comments supporting a reading of the mind-body relation as a substantial union, his physiological writings on generation and his idea of ‘life’ contradict this interpretation. -/- .
