Since the publication of David Lewis's ''New Work for a Theory of Universals,'' the distinction between properties that are fundamental – or perfectly natural – and those that are not has become a staple of mainstream metaphysics. Plausible candidates for perfect naturalness include the quantitative properties posited by fundamental physics. This paper argues for two claims: (1) the most satisfying account of quantitative properties employs higher-order relations, and (2) these relations must be perfectly natural, for otherwise the perfectly natural properties (...) cannot play the roles in metaphysical theorizing as envisaged by Lewis.

Powers are popularly assumed to be distinct from, and dependent upon, inert qualities, mainly because it is believed that qualities have their nature independently of other properties while powers have their nature in virtue of a relation to distinct manifestation property. George Molnar and Alexander Bird, on the other hand, characterize powers as intrinsic and relational. The difficulties of reconciling the characteristics of being intrinsic and at the same time essentially related are illustrated in this paper and it is (...) argued that the reasons for thinking of powers as essentially relational are based on misguided epistemological consideration. Finally, I present a way of thinking of fundamental properties as primitive natures that we can only understand in virtue of what they do but which we should not think of as being ontologically constituted by these doings. According to this view, properties are both qualities and powers. (shrink)

Two grams mass, three coulombs charge, five inches long – these are examples of quantitative properties. Quantitative properties have certain structural features that other sorts of properties lack. What are the metaphysical underpinnings of quantitative structure? This paper considers several accounts of quantity and assesses the merits of each.

Our prominent definitions of cognition are too vague and lack empirical grounding. They have not kept up with recent developments, and cannot bear the weight placed on them across many different debates. I here articulate and defend a more adequate theory. On this theory, behaviors under the control of cognition tend to display a cluster of characteristic properties, a cluster which tends to be absent from behaviors produced by non-cognitive processes. This cluster is reverse-engineered from the empirical tests that comparative (...) psychologists use to determine whether a behavior was generated by a cognitive or a non-cognitive process. Cognition should be understood as the natural kind of psychological process that non-accidentally exhibits the properties assessed by these tests (as well as others we have not yet discovered). Finally, I review two plausible neural accounts of cognition's underlying mechanisms?one based in localization of function to particular brain regions and another based in the more recent distributed networks approach to neuroscience?which would explain why these properties non-accidentally cluster. While this notion of cognition may be useful for a number of debates, I here focus on its application to a recent crisis over the distinction between cognition and association in comparative psychology.

The homeostatic property cluster theory is widely influential for its ability to account for many natural-kind terms in the life sciences. However, the notion of homeostatic mechanism has never been fully explicated. In 2009, Carl Craver interpreted the notion in the sense articulated in discussions on mechanistic explanation and pointed out that the HPC account equipped with such notion invites interest-relativity. In this paper, we analyze two recent refinements on HPC: one that avoids any reference to the causes of (...) the clustering of properties and one that replaces homeostatic mechanisms with causal networks represented by causal graphs. We argue that the former is too slender to account for some inductive inference in science and the latter, thicker account invites interest-relativity, as the original HPC does. This suggests that human interest will be an un-eliminative part of a satisfactory account of natural kindness. We conclude by discussing the implication of interest-relativity to the naturalness, reality, or objectivity of kinds and indicating an overlooked aspect of natural kinds that requires further studies.

I argue that the best scientific package is anti-Humean in its ontology, but Humean in its laws. This is because potencies and the best system account of laws complement each other surprisingly well. If there are potencies, then the BSA is the most plausible account of the laws of nature. Conversely, if the BSA is the correct theory of laws, then formulating the laws in terms of potencies rather than categorical properties avoids three serious objections: the mismatch objection, the impoverished (...) worlds objection, and the metaphysical 'oomph' objection. I argue that combining anti-Humean properties with Humean laws into a Potency-Best System Account of Laws is a powerful and science-friendly account---something that people on both sides should be able to appreciate.

This paper provides an analysis of the intrinsic/extrinsic distinction, as applied both to properties and to relations. In contrast to other accounts, the approach taken here locates the source of a property’s intrinsicality or extrinsicality in the manner in which that property is ‘logically constituted’, and thus – plausibly – in its nature or essence, rather than in e.g. its modal profile. Another respect in which the present proposal differs from many extant analyses lies in the fact that (...) it does not seek to analyse the ‘global’ distinction between intrinsic and extrinsic properties on the basis of the ‘local’ distinction between having a property intrinsically and having it extrinsically. Instead, the latter distinction is explicated on the basis of the former. (shrink)

According to Essentialism, an object’s properties divide into those that are essential and those that are accidental. While being human is commonly thought to be essential to Socrates, being a philosopher plausibly is not. We can motivate the distinction by appealing—as we just did—to examples. However, it is not obvious how best to characterize the notion of essential property, nor is it easy to give conclusive arguments for the essentiality of a given property. In this paper, I elaborate (...) on these issues and explore the way in which essential properties behave in relation to other related properties, like sufficient-for-existence properties and individual essences.

New developments in biotechnology radically alter our relationship with our bodies. Body tissues can now be used for commercial purposes, while external objects, such as pacemakers, can become part of the body. Property in the Body: Feminist Perspectives transcends the everyday responses to such developments, suggesting that what we most fear is the feminisation of the body. We fear our bodies are becoming objects of property, turning us into things rather than persons. This book evaluates how well-grounded this (...) fear is, and suggests innovative models of regulating what has been called 'the new Gold Rush' in human tissue. This is an up-to-date and wide-ranging synthesis of market developments in body tissue, bringing together bioethics, feminist theory and lessons from countries that have resisted commercialisation of the body, in a theoretically sophisticated and practically significant approach.

While it is well known that the early Heidegger distinguishes between different ‘kinds of being’ and identifies various ‘structures’ that compose them, there has been little discussion about what these kinds and structures of being are. This paper defends the ‘Property Thesis’, the position that kinds of being (and their structures) are properties of the entities that have them. I give two arguments for this thesis. The first is grounded in the fact that Heidegger refers to kinds and structures (...) of being as ‘characteristics’ and ‘determinations’, which are just two different words for ‘properties’, in the broadest senses of these terms. The second argument is based on the fact that kinds and structures of being play three roles that properties are supposed to play: they are what account for similarities between things, they are what predicates express, and they are what abstract nouns refer to.

This paper puts forward the hypothesis that the distinctive features of quantum statistics are exclusively determined by the nature of the properties it describes. In particular, all statistically relevant properties of identical quantum particles in many-particle systems are conjectured to be irreducible, ‘inherent’ properties only belonging to the whole system. This allows one to explain quantum statistics without endorsing the ‘Received View’ that particles are non-individuals, or postulating that quantum systems obey peculiar probability distributions, or assuming that there are primitive (...) restrictions on the range of states accessible to such systems. With this, the need for an unambiguously metaphysical explanation of certain physical facts is acknowledged and satisfied. (shrink)

This paper aims to build a bridge between two areas of philosophical research, the structure of kinds and metaphysical modality. Our central thesis is that kinds typically involve super-explanatory properties, and that these properties are therefore metaphysically essential to natural kinds. Philosophers of science who work on kinds tend to emphasize their complexity, and are generally resistant to any suggestion that they have “essences”. The complexities are real enough, but they should not be allowed to obscure the way that kinds (...) are typically unified by certain core properties. We shall show how this unifying role offers a natural account of why certain properties are metaphysically essential to kinds. (shrink)

A theory of property needs to give an account of the whole life-cycle of a property right: how it is initiated, transferred, and terminated. Economics has focused on the transfers in the market and has almost completely neglected the question of the initiation and termination of property in normal production and consumption (not in some original state or in the transition from common to private property). The institutional mechanism for the normal initiation and termination of (...) class='Hi'>property is an invisible-hand function of the market, the market mechanism of appropriation. Does this mechanism satisfy an appropriate normative principle? The standard normative juridical principle is to assign or impute legal responsibility according to de facto responsibility. It is given a historical tag of being "Lockean" but the basis is contemporary jurisprudence, not historical exegesis. Then the fundamental theorem of the property mechanism is proven which shows that if "Hume's conditions" (no transfers without consent and all contracts fulfilled) are satisfied, then the market automatically satisfies the Lockean responsibility principle, i.e., "Hume implies Locke." As a major application, the results in their contrapositive form, "Not Locke implies Not Hume," are applied to a market economy based on the employment contract. It is shown the production based on the employment contract violates the Lockean principle (all who work in an employment enterprise are de facto responsible for the positive and negative results) and thus Hume's conditions must also be violated in the marketplace (de facto responsible human action cannot be transferred from one person to another—as is readily recognized when and employer and employee together commit a crime).

The fact that you see some particular object seems to be due to the causal relation between your visual experience and that object, rather than to your experiences’ phenomenal character. On the one hand, whenever some phenomenal element of your experience stands in the right sort of causal relation to some object, your experience presents that object (your experience’s phenomenology doesn’t need to match that object). On the other hand, you can’t have a perceptual experience that presents some object unless (...) you stand in the right sort of causal relation to that object (no matter how closely your experience’s phenomenology matches some object). According to the continuity thesis, property perception is similar to object perception in these two respects. A standard reason to reject the continuity thesis is the assumption that the environmental properties that a perceptual experience presents are determined by its phenomenal properties (which are not determined by the environmental properties that cause the experience). I maintain that the continuity thesis is false but for a different reason: perceptual experiences present both objects and properties via manners of presentation; but, whereas perceptual manners of presentation for objects are purely relational, perceptual manners of presentation for properties are satisfactional.

Drawing on empirical evidence from history and anthropology, we aim to demonstrate that there is room for genealogical ideology critique within normative political theory. The test case is some libertarians’ use of folk notions of private property rights in defence of the legitimacy of capitalist states. Our genealogy of the notion of private property shows that asking whether a capitalist state can emerge without violations of self-ownership cannot help settling the question of its legitimacy, because the notion of (...) private property presupposed by that question is a product of the entity it is supposed to help legitimise: the state. We anchor our genealogical critique in recent work on ideology in epistemology and philosophy of language, and in current debates on the methodology of political theory. But, unlike more traditional approaches that aim to debunk whole concepts or even belief systems, we propose a more targeted, argument-specific form of ideology critique. (shrink)

It is argued that, because of scientific essentialism, two currently popular arguments against the mind-body identity thesis -- the multiple-realizability argument and the Nagel-Jackson knowledge argument -- are unsatisfactory as they stand and that their problems are incurable. It is then argued that a refutation of the identity thesis in its full generality can be achieved by weaving together two traditional Cartesian arguments -- the modal argument and the certainty argument. This argument establishes, not just the falsity of the identity (...) thesis, but also the metaphysical possibility of disembodiment. (shrink)

Three objections have recently been levelled at the analysis of intrinsicness offered by Rae Langton and David Lewis. While these objections do seem telling against the particular theory Langton and Lewis offer, they do not threaten the broader strategy Langton and Lewis adopt: defining intrinsicness in terms of combinatorial features of properties. I show how to amend their theory to overcome the objections without abandoning the strategy.

Can we employ the property of rationality in establishing what rationality requires? According to a central and formal thesis of John Broome’s work on rational requirements, the answer is ‘no’ – at least if we expect a precise answer. In particular, Broome argues that (i) the property of full rationality (i.e. whether or not you are fully rational) is independent of whether we formulate conditional requirements of rationality as having a wide or a narrow logical scope. That is, (...) (ii) by replacing a wide-scope requirement with a corresponding narrow-scope requirement (or vice versa), we do not alter the situations in which a person is fully rational. As a consequence, (iii) the property of full rationality is unable to guide us in determining whether a rational requirement has a wide or a narrow logical scope. We cannot resolve the wide/narrow scope debate by appealing to a theory of fully rational attitudes. This paper argues that (i), (ii) and (iii) are incorrect. Replacing a wide- with a corresponding narrow-scope requirement (or vice versa) can alter the set of circumstances in which a person is fully rational. The property of full rationality is therefore not independent of whether we formulate conditional requirements of rationality as having a wide or a narrow logical scope. As a consequence, the property of full rationality can guide us in determining what rationality requires – even in cases where we expect a precise answer. (shrink)

This book is both an introduction to and a research work on Meinongianism. “Meinongianism” is taken here, in accordance with the common philosophical jargon, as a general label for a set of theories of existence – probably the most basic notion of ontology. As an introduction, the book provides the first comprehensive survey and guide to Meinongianism and non-standard theories of existence in all their main forms. As a research work, the book exposes and develops the most up-to-date Meinongian theory (...) (called modal Meinongianism), applies it to specific fields, and discusses its open problems. Part I of the book provides a historical introduction to, and critical discussion of, the dominant philosophical view of existence: the “Kantian-Fregean-Quinean” perspective. Part II is the full-fledged introduction to the Meinongian theories of existence as a real property of individuals: after starting with the so-called naïve Meinongian conception and its problems, it provides a self-contained presentation of the main neo-Meinongian proposals, and a detailed discussion of their strengths and weaknesses. Part III develops a specific neo-Meinongian theory of existence employing a model-theoretic semantic framework. It discusses its application to the ontology and semantics of fictional objects, and its open problems. The methodology of the book follows the most recent trends in analytic ontology. In particular, the meta-ontological point of view is largely privileged. (shrink)

Theories of singular causation have a genuine problem with properties. In virtue of what property do events (or facts) cause other events? One possible answer to this question, Davidson’s, is that causal relations hold between particulars and properties play no role in the way a particular causes another. According to another, recently fashionable answer, in contrast, events cause other events in virtue of having a trope (as opposed to a property-type). Both views face serious objections. My aim in (...) this paper is to combine these two very different solutions to the problem of the properties of singular causation and to argue that this combined view can avoid objections against both of them.

The paper argues that members of future generations have an entitlement to natural resources equal to ours. Therefore, if a currently living individual destroys or degrades natural resources then he must pay compensation to members of future generations. This compensation takes the form of “primary goods” which will be valued by members of future generations as equally useful for promoting the good life as the natural resources they have been deprived of. As a result of this policy, each generation inherits (...) a “Commonwealth” of natural resources plus compensation. It is this inherited “Commonwealth” which members of that generation must then pass on to members of the next generation. Once this picture is accepted, the standard bundle of property rights is problematic, for it takes the owner of a constituent of the Commonwealth to have the right to “waste, destroy or modify” that item at will. This paper therefore presents a revised set of property rights which takes seriously the idea that each generation has an equal claim on the resources that nature has bequeathed us, whilst allowing certain effects on those natural resources by each generation, and a degree of exclusive use of those natural resources owned by an individual.

The moral justification of intellectual property is often called into question when placed in the context of pharmaceutical patents and global health concerns. The theoretical accounts of both John Rawls and Robert Nozick provide an excellent ethical framework from which such questions can be clarified. While Nozick upholds an individuals right to intellectual property, based upon its conformation with Lockean notions of property and Nozicks ideas of just acquisition and transfer, Rawls emphasizes the importance of basic liberties, (...) such as an individuals right to health, superceding such secondary rights as intellectual property rights. From a policy perspective, patent protection for pharmaceutical products necessarily entails the balancing of corporate intellectual property interests and public interests in healthcare. The moral dilemma that occurs when these two interests clash is not easily resolved. Aside from corporate and public interests, the state maintains an interest in creating and preserving policies that regulate the moral dilemma itself. This paper analyzes the economic and ethical factors surrounding the production and distribution of the anti-HIV medication, AZT. Potential policy implications and recommendations are also discussed.

Intellectual property has become the apple of discord in today’s moral and political debates. Although it has been approached from many different perspectives, a final conclusion has not been reached. In this paper I will offer a new way of thinking about intellectual property rights (IPRs), from a left-libertarian perspective. My thesis is that IPRs are not (natural) original rights, aprioric rights, as it is usually argued. They are derived rights hence any claim for intellectual property is (...) weaker than the correlative duties attached to self-ownership and world-ownership rights, which are of crucial importance in any left-libertarian view. Moreover, IPRs lack priority in front of these two original rights and should be overridden by stronger claims of justice. Thus, as derived rights, IPRs should not benefit of strong enforcement like any original rights especially if it could be in the latters’ detriment. (shrink)

What is the connection between having a phenomenal property and knowing that one has that property? A traditional view on the matter takes the connection to be quite intimate. Whenever one has a phenomenal property, one knows that one does. Recently most authors have denied this traditional view. The goal of this paper is to defend the traditional view. In fact, I will defend something much stronger: I will argue that what it is for a property (...) to be phenomenal is for it to be a property one must know oneself to have when on has it. As we will see, this theory has a number of surprising and welcome upshots, suggesting that the traditional view has been unjustly maligned. (shrink)

This paper presents an account of what it is for a property or relation (or ‘attribute’ for short) to be logically simple. Based on this account, it is shown, among other things, that the logically simple attributes are in at least one important way sparse. This in turn lends support to the view that the concept of a logically simple attribute can be regarded as a promising substitute for Lewis’s concept of a perfectly natural attribute. At least in part, (...) the advantage of using the former concept lies in the fact that it is amenable to analysis, where that analysis—i.e., the account put forward in this paper—requires the adoption neither of an Armstrongian theory of universals nor of a primitive notion of naturalness, fundamentality, or grounding.

The distinction between qualitative and non-qualitative properties should be familiar from discussions of the principle of the identity of indiscernibles: two otherwise exactly similar individuals, Castor and Pollux, might share all their qualitative properties yet differ with respect to their non-qualitative properties—for while Castor has the property being identical to Castor, Pollux does not. But while this distinction is familiar, there has not been much critical attention devoted to spelling out its precise nature. I argue that the class of (...) non-qualitative properties is broader than it is often taken to be. When properly construed, it will not only include properties such as being identical to Castor, which somehow make reference to particular individuals, it will also include more general properties such as identity, composition, set membership, as well as various peculiarly ontological properties. Given that some of these more general properties help to explain objective similarity, we have reason to believe that there are fundamental non-qualitative properties. (shrink)

Within a liberal, ‘law of things’ understanding of property, the donative trust is seen as a species of gift. Control over trust property passes from the hands of settlors to beneficiaries, from owners to owners. Trust property, like all other property, is silent and passive, its fate determined by its owners. This article questions this understanding of the trust by showing how beneath the facade of ownership, the trust inverts the relation between owner and owned, person (...) and thing. It analyses the relation that trustees, beneficiaries and settlors have to the trust property and argues that the role of each of these parties can be shown to consist in furthering the interests of the trust property rather than their own. It claims that this protects things from their owners at the same time as it ensures these owners’ ongoing care towards the things they own. This raises questions about the trust’s status within the institution of private property, justified as it is by the human autonomy it is said to enable. (shrink)

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.

This book contributes to the feminist reconstruction of political theory. Although many feminist authors have pointed out the ways in which women have been property, they have been less successful in suggesting how women might become the subjects rather than the objects of property-holding. This book synthesises political theory from liberal, Marxist, Kantian and Hegelian traditions, applying these ideas to history and social policy.

An intrinsic property, according to one important account, is a property that is had by all of one's duplicates. Instead, one might choose to characterize intrinsic properties as those that can be had in the absence of all distinct individuals. After reviewing the problems with these earlier accounts, the author presents a less problematic analysis. The goal is to clarify the rough idea that an intrinsic property is a special sort of non-relational property; having the (...) class='Hi'>property does not consist in any relation one bears to distinct individuals.

The interpretation of Lewis‘s doctrine of natural properties is difficult and controversial, especially when it comes to the bearers of natural properties. According to the prevailing reading – the minimalist view – perfectly natural properties pertain to the micro-physical realm and are instantiated by entities without proper parts or point-like. This paper argues that there are reasons internal to a broadly Lewisian kind of metaphysics to think that the minimalist view is fundamentally flawed and that a liberal view, according to (...) which natural properties are instantiated at several or even at all levels of reality, should be preferred. Our argument proceeds by reviewing those core principles of Lewis‘s metaphysics that are most likely to constrain the size of the bearers of natural properties: the principle of Humean supervenience, the principle of recombination in modal realism, the hypothesis of gunk, and the thesis of composition as identity.

This paper studies a formalisation of intuitionistic logic by Negri and von Plato which has general introduction and elimination rules. The philosophical importance of the system is expounded. Definitions of ‘maximal formula’, ‘segment’ and ‘maximal segment’ suitable to the system are formulated and corresponding reduction procedures for maximal formulas and permutative reduction procedures for maximal segments given. Alternatives to the main method used are also considered. It is shown that deductions in the system convert into normal form and that deductions (...) in normal form have the subformula property.

This article aims to clarify how aspects of current chemical understanding relate to some important contemporary problems of philosophy. The first section points out that the long-running philosophical debates concerning how properties stay together in substances have neglected the important topic of structure-determining closure. The second part describes several chemically-important types of closure and the third part shows how such closures ground the properties of chemical substances. The fourth section introduces current discussions of structural realism (SR) and contextual emergence: the (...) final sections reconsider the coherence of the properties of substances and concludes that recognition that structures qualify as determinants of specific outcomes—as ‘causes’ as that designation is used in Standard English—clarifies how properties stay together in chemical entities, and by analogy, how characteristics cohere in ordinary items.

This paper considers a formalisation of classical logic using general introduction rules and general elimination rules. It proposes a definition of ‘maximal formula’, ‘segment’ and ‘maximal segment’ suitable to the system, and gives reduction procedures for them. It is then shown that deductions in the system convert into normal form, i.e. deductions that contain neither maximal formulas nor maximal segments, and that deductions in normal form satisfy the subformula property. Tarski’s Rule is treated as a general introduction rule for (...) implication. The general introduction rule for negation has a similar form. Maximal formulas with implication or negation as main operator require reduction procedures of a more intricate kind not present in normalisation for intuitionist logic. (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)

This essay examines the metaphysical foundation of Leibniz’s theory of space against the backdrop of the subtantivalism/relationism debate and at the ontological level of material bodies and properties. As will be demonstrated, the details of Leibniz’ theory defy a straightforward categorization employing the standard relationism often attributed to his views. Rather, a more careful analysis of his metaphysical doctrines related to bodies and space will reveal the importance of a host of concepts, such as the foundational role of God, the (...) holism of both geometry and the material world’s interconnections, and the viability and adequacy of a property theory in characterizing his natural philosophy of space.

This paper defends the case against (sparse) disjunctive properties by means of four Armstrongian arguments. The first of these is a logical atomist argument from truthmaking, which is, broadly speaking, ‘Armstrongian’ (Armstrong 1997). This argument is strong – although it stands or falls with the relevant notion of truthmaking, as it were. However, three arguments, which are prima facie independent of truthmaking, can be found explicitly early in Armstrong’s middle period. Two of these early arguments face a serious objection put (...) forward forcefully by Louise Antony (2003) and Alan Penczek (1997), respectively. I consider these objections and argue that they fail. Thus, even if the argument from truthmaking is indecisive, disjunctive properties should be rejected. (shrink)

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)

This paper examines some consequences of the (quasi-)epiphenomenalism implied by a property dualistic view of phenomenal consciousness. The focus is upon the variation of phenomenal content over time. A thought-experiment is constructed to support two claims. The weaker claim exhibits an incompatibility which arises in certain logically possible situations between a conscious subject’s epistemic norms and the requirement that one be aware of one’s conscious experience. This could be interpreted as providing some epistemic grounds for the postulation of bridging (...) laws between the physical/functional and phenomenal domains. The stronger claim has it that the ontology of property dualism is not properly able to account for the certainty I have of being phenomenally conscious. The problem is viewed as resulting from the neglect of the intensional context involved in a proper representation of the argument for property dualism. It is argued that only a transcendental move can do justice to this certainty I have. (shrink)

Tim Bayne and Susanna Siegel have recently offered interesting arguments in favor of the view that we can experience high-level properties like being a pine tree or being a stethoscope (Bayne 2009, Siegel 2006, 2011). We argue first that Bayne’s simpler argument fails. However, our main aim in this paper is to show that Siegel’s more sophisticated argument for her version of the high-level view can also be resisted if one adopts a view that distinguishes between perceptual experiences and seemings.

A problem for Aristotelian realist accounts of universals (neither Platonist nor nominalist) is the status of those universals that happen not to be realised in the physical (or any other) world. They perhaps include uninstantiated shades of blue and huge infinite cardinals. Should they be altogether excluded (as in D.M. Armstrong's theory of universals) or accorded some sort of reality? Surely truths about ratios are true even of ratios that are too big to be instantiated - what is the truthmaker (...) of such truths? It is argued that Aristotelianism can answer the question, but only a semi-Platonist form of it. (shrink)

A critical but underdeveloped part of the libertarian debate about immigration is the question of who, if anyone, owns public property, and the consequences of the answer to this question. Libertarians who favor restrictive immigration policies, such as Hans-Hermann Hoppe, argue that taxpayers own public property, and that the state, while it is in control of such property, should manage it on behalf of taxpayers in the same way private owners would manage their own property. In (...) other words, it should be quite selective about who may enter. Walter Block, who takes an “open borders” position, does not appear to dispute the claim that taxpayers own public property, but nevertheless argues that immigrants are entitled to ignore the state’s control of, and thus may freely enter, such property. In this article I explore the question of public property ownership using Rothbardian property rights principles. I conclude that, at least with respect to a particular type of public property, neither Hoppe’s nor Block’s reasoning is consistent with these principles. I also consider the idea that the state ought to have a role in managing public property in light of some libertarian anarchist ideas about the state. I conclude that supporting a legitimate role for the state as an immigration gatekeeper is inconsistent with Rothbardian and Hoppean libertarian anarchism, as well as with the associated strategy of advocating always and in every instance reductions in the state’s role in society.

It is widely held that some properties are more natural than others and that, as David Lewis put it, “an adequate theory of properties is one that recognises an objective difference between natural and unnatural properties” (Lewis 1983, p. 347). The general line of thought is that such ‘elitism’ about properties is justified as it can give simple and elegant solutions to a number of old metaphysical and philosophical problems. My aim is to analyze what these natural properties are: super-determinates (...) or determinable (or maybe both) and argue that all three of these options would lead to serious difficulties for metaphysical elitism and would prevent natural properties from fulfilling their supposed grand explanatory role.

Book review of 'Tropes: Properties, Objects, and Mental Causation' (2011, OUP). By DOUGLAS EHRING.

I present and defend a novel version of the homeostatic property cluster account of natural kinds. The core of the proposal is a development of the notion of co-occurrence, central to the HPC account, along information-theoretic lines. The resulting theory retains all the appealing features of the original formulation, while increasing its explanatory power, and formal perspicuity. I showcase the theory by applying it to the problem of reconciling the thesis that biological species are natural kinds with the fact (...) that many such species are polymorphic. (shrink)

Mainstream analytic epistemology regards knowledge as the property of individuals, rather ‎than groups. Drawing on insights from the reality of knowledge production and dissemination ‎in the sciences, I argue, from within the analytic framework, that this view is wrong. I defend ‎the thesis of ‘knowledge-level justification communalism’, which states that at least some ‎knowledge, typically knowledge obtained from expert testimony, is the property of a ‎community and possibly none of its individual members, in that only the community or (...) some ‎members of it collectively possesses knowledge-level justification for its individual members’ ‎beliefs. I address several objections that individuals, qua individuals, have or are able to ‎acquire knowledge-level justification for all the beliefs they obtain from expert testimony. I ‎argue that the problem I identify with individualism is invariant under any specific account of ‎justification, internalist or externalist. ‎. (shrink)
