Properties

Egan argues against Lewis’s view that properties are sets of actual and possible individuals and in favour of the view that they are functions from worlds to extensions (sets of individuals). Egan argues that Lewis’s view implies that 2nd order properties are never possessed contingently by their (1st order) bearers, an implication to which there are numerous counter-examples. And Egan argues that his account of properties is more commensurable with the role they play as the semantic values of predicates than (...) is Lewis’s. (shrink)

My main reaction to MCGivern’s paper was one of dialectical puzzlement. Block argues that, Macro Non-Reduction: [all] macro properties are irreducible to the micro properties on which they supervene..

This paper provides an account of the closure conditions that apply to sets of subvening and supervening properties, showing that the criterion that determines under which property-forming operations a particular family of properties is closed is applicable both to the finitary and to the infinitary case. In particular, it will be established that, contra Glanzberg, infinitary operations do not give rise to any additional difficulties beyond those that arise in the finitary case.

Dispositional essentialism maintains that all sparse properties are essentially powerful. Two conceptions of sparse properties appear compatible with dispositional essentialism: sparse properties as pure powers or as powerful qualities. This paper compares the two views, criticizes the powerful qualities view, and then develops a new theory of pure powers, termed Point Theory. This theory neutralizes the main advantage powerful qualities appear to possess over pure powers—explaining the existence of powers during latency periods. The paper discusses the relation between powers and (...) space-time points, whether pure powers need to occupy space, and how to account for the movement of pure powers through space-time. Given Point Theory, dispositional essentialists should maintain that sparse properties are pure powers. (shrink)

In the world there are concrete particulars that exhibit the kind of substantial unity that allows them to be called substances or “natural individuals”, as opposed to artifacts or mere conglomerates. Persons, animals, and possibly the most fundamental physical simples are all natural individuals. What gives these entities the ontological status of a substantial unity? Arguments from the philosophy of mind and arguments from general metaphysics show that physical properties alone cannot account for substantial unity. The ultimate intrinsic properties of (...) natural individuals resemble phenomenal mental properties rather than any other kind of known properties. Pan(proto-)psychism is thus supported by systematically related arguments from different areas of philosophical inquiry. A certain amount of skepticism regarding the full nature of absolutely intrinsic properties is nevertheless well-advised. (shrink)

What is the relationship between sounds and time? More specifically, is there something essentially or distinctively temporal about sounds that distinguishes them from, say, colors, shapes, odors, tastes, or other sensible qualities? And just what might this distinctive relation to time consist in? Apart from their independent interest, these issues have a number of important philosophical repercussions. First, if sounds are temporal in a way that other sensible qualities are not, then this would mean that standard lists of paradigm secondary (...) qualities offered by Locke, Galileo, and other modern philosophers — lists which include colors, odors and sounds without any significant distinctions — overlook significant metaphysical differences. This, in turn, would threaten to undermine the coherence of the modern understanding of secondary qualities itself. Moreover, a number of authors have recently urged that the essential temporality of sounds makes it impossible to understand sounds as properties (except on a trope theory of properties; see note 3). If true, and given the more or less universal view that colors are properties, this last conclusion would make potentially inapplicable to sounds much of the comparatively well-developed philosophical taxonomy and apparatus that has arisen in philosophical disputes over the status of colors (for presentations of this taxonomy and apparatus see, for example, Byrne and Hilbert (2003); Cohen (2008b)).1 Therefore, the conclusion that sounds are distinctively temporal would be a serious blow to hopes for a theoretically unified treatment of the sensory qualities.2 For all these reasons, quite a lot seems to hang on the question of the temporality of sounds.

Mereological nihilism is the view that there are no composite objects; everything in existence is mereologically simple. The view is subject to a number of difficulties, one of which concerns what I call the problem of emergence. Very briefly, the problem is that nihilism seems to be incompatible with emergent properties; it seems to rule out their very possibility. This is a problem because there are good independent reasons to believe that emergent properties are possible. This paper provides a solution (...) to the problem. I will show that nihilism and emergence are perfectly compatible, providing one accepts a novel understanding of how objects can instantiate properties: what I call irreducibly collective instantiation.

The distinction between qualitative properties like mass and shape and non-qualitative properties like being Napoleon and being next to Obama is important, but remains largely unexamined. After discussing its theoretical significance and cataloguing various kinds of non-qualitative properties, I survey several views about the nature of this distinction and argue that all proposed reductive analyses of this distinction are unsatisfactory. I then defend primitivism, according to which the distinction resists reductive analysis.

Is it possible and necessary to admit of non-physical properties? A minimal ontology accepts only the reality of physical properties. It is based on a restrictive existential criterion, namely the causal criterion. On the contrary, a fostering ontology insists that at least some non-physical properties are real, and therefore denies the validity of the causal criterion. The purpose of this investigation is to defend a moderate version of realism with regard to non-physical properties and to suggest a new existential criterion (...) for properties: the explicative criterion.RésuméPeut-on et doit-on admettre des propriétés non physiques ? Une ontologie minimale accepte seulement la réalité des propriétés physiques. Elle prend appui sur un critère d’existence restreint : le critère causal. A l’inverse, une ontologie d’accueil affirme la réalité d’au moins certaines propriétés non physiques, et conteste par là la validité du critère causal. Le but de cette investigation est de défendre une version modérée du réalisme par rapport aux propriétés non physiques et de proposer un nouveau critère d’existence : le critère explicatif. (shrink)

The world is populated with many different objects, to which we often attribute properties: we say, for example, that grass is green, that the earth is spherical, that humans are animals, and that murder is wrong. We also take it that these properties are things in their own right: there is something in which being green, or spherical, or an animal, or wrong, consists, and that certain scientific or normative projects are engaged in uncovering the essences of such properties. In (...) light of this, an important question arises: what kind of things should we take properties themselves to be? -/- In Properties, Douglas Edwards gives an engaging, accessible, and up-to-date introduction to the many theories of properties available. Edwards charts the central positions in the debate over properties, including the views that properties are universals, that properties are constructed from tropes, and that properties are classes of objects, and assesses the benefits and disadvantages of each. Attempts to deny the existence of properties are also considered, along with ‘pluralist’ proposals, which aim to accommodate the different kinds of properties that are found in various philosophical debates. -/- Properties is the ideal introduction to this topic and will be an invaluable resource for scholars and students wishing to learn more about the important roles that properties have played, and continue to play, in contemporary philosophy.

This paper argues that, assuming properties exist and must be located in spacetime, the prevailing view that they are exactly located where their instances are is false. Instead a property is singularly located at just one region, namely the union of its instance's locations. This bears not just on issues in the metaphysics of properties, but also on the debate over whether multi-location is conceivable and/or possible.

Classical physics and quantum physics suggest two meta-physical types of reality: the classical notion of a objectively definite reality with properties "all the way down," and the quantum notion of an objectively indefinite type of reality. The problem of interpreting quantum mechanics (QM) is essentially the problem of making sense out of an objectively indefinite reality. These two types of reality can be respectively associated with the two mathematical concepts of subsets and quotient sets (or partitions) which are category-theoretically dual (...) to one another and which are developed in two mathematical logics, the usual Boolean logic of subsets and the more recent logic of partitions. Our sense-making strategy is "follow the math" by showing how the logic and mathematics of set partitions can be transported in a natural way to Hilbert spaces where it yields the mathematical machinery of QM--which shows that the mathematical framework of QM is a type of logical system over ℂ. And then we show how the machinery of QM can be transported the other way down to the set-like vector spaces over ℤ₂ showing how the classical logical finite probability calculus (in a "non-commutative" version) is a type of "quantum mechanics" over ℤ₂, i.e., over sets. In this way, we try to make sense out of objective indefiniteness and thus to interpret quantum mechanics. (shrink)

Abstract This paper argues that there are good reasons to adopt a non-reductive account of states when it comes to quantum mechanics. That is to say, it is argued that there are advantages to thinking about states as sui generis, as reducible to classes of values of quantities, when it comes to the quantum domain. One reason for holding this view is that it seems to improve the prospects for explanation. In more detail, it is argued that there is an (...) 'explanatory shortfall' in the quantum domain owing to the failure of value definiteness. To remedy this situation, two proposals are put forward about the nature of the quantum state: Proposal A, that the quantum state is the only first-order property of quantum systems, Proposal B, that the quantum state is one first-order property among many. These proposals seem equally good. (shrink)

The relationship between alethic modality and indeterminacy is yet to be clarified. A modal argument—an argument that appeals to alethic modality—against vague objects given by Joseph Moore offers a potential clarification of the relationship; it is proposed that there are cases for which the following holds: if it is indeterminate whether A = B then it is possible that it is determinate that A = B. However, the argument faces three problems. The problems remove the argument’s threat against vague objects (...) and prompt a fuller scrutiny of Moore’s proposed relationship between alethic modality and indeterminacy. Such a scrutiny offers valuable lessons concerning the justification for claims of indeterminate identity, appeals to identity principles in contexts involving both alethic modality and indeterminacy, and how to identify the form of Gareth Evans’s argument against vague objects in other arguments.

A new realist interpretation of quantum mechanics is introduced. Quantum systems are shown to have two kinds of properties: the usual ones described by values of quantum observables, which are called extrinsic, and those that can be attributed to individual quantum systems without violating standard quantum mechanics, which are called intrinsic. The intrinsic properties are classified into structural and conditional. A systematic and self-consistent account is given. Much more statements become meaningful than any version of Copenhagen interpretation would allow. A (...) new approach to classical properties and measurement problem is suggested. A quantum definition of classical states is proposed. (shrink)

An important challenge to color objectivists, who hold that statements concerning color are made true or false by objective (non-subject-involving) facts, is the argument from interpersonal variation in where normal observers locate the unique hues. Recently, an attractive objectivist response to the argument has been proposed that draws on the semantics of gradable adjectives and which does not require defending the idea that there is a single correct location for each of the unique hues (Gómez-Torrente, 2016). In Hansen (2015), I (...) argued that the recent objectivist response doesn’t apply to comparative occurrences of color adjectives, so a revised, comparative, version of the argument from interpersonal variation remains a powerful objection to certain types of objectivism. In this paper, I address several unsatisfactory objectivist replies to the comparative version of the argument from interpersonal variation, and offer what I think is a more plausible objectivist reply to the comparative argument from interpersonal variation.

Der Topos von der Unerschöpflichkeit des Gegenstands wird mit der Phänomenologie assoziiert. Den ihm verwandten Topos von der Unaussprechlichkeit des Individuellen haben Goethe und die deutschen Romantiker in die Welt getragen. Der Diktion der analytischen Philosophie sind die Ausdrücke „unerschöpflich“ und „unaussprechlich“ fremd. Dieser Umstand sollte analytische Philosophen nicht davon abhalten, sich den sprachphilosophischen und ontologischen Problemen zuzuwenden, die sich hinter den besagten Formeln verbergen. Husserls Wort für Unerschöpflichkeit ist „Fülle“. Die „Fülle des Gegenstandes“ erläutert Husserl als den „Inbegriff der (...) ihn konstituierenden Bestimmtheiten“, seine „individualisierenden Bestimmtheiten“ eingeschlossen. Ich werde in diesem Aufsatz von deskriptiver Unerschöpflichkeit sprechen, die ich auf eine ontische Eigenart der konkreten Einzeldinge zurückführe. Den Begriff der deskriptiven Unerschöpflichkeit werde ich zunächst anhand des Problems entwickeln, die Eigenschaften eines Einzeldings zu zählen. Aristoteles, Leibniz und Kant beantworten die Frage, wie viele Eigenschaften ein Einzelding hat, gleichlautend: es sind potentiell unendlich viele (1.). Die ontologische Kategorie, für die dies gilt, ist die der konkreten, raumzeitlichen Einzeldinge (2.). Unter (3.) wird der Befund der deskriptiven Unerschöpflichkeit näher erläutert und ausdifferenziert. Unter (4.) wird ein sprachphilosophisch motivierter Einwand gegen die Unerschöpflichkeitsthese diskutiert und zurückgewiesen: der Einwand aus der endlichen Zahl der Prädikate. Dann werde ich die Begriffe Leerstelle, Auflösung und ontische Dichte einführen, um meinen Befund zu sichern und zu präzisieren (5.). Unter dem Stichwort „Unerschöpflich oder bloß faktisch unerschöpft?“ diskutiere ich die Frage, worin das prinzipielle Hindernis für das Unternehmen liegen soll, ein Einzelding erschöpfend zu beschreiben (6.). Anschließend kontrastiere ich die Unerschöpflichkeitsthese mit der pathetischen Formel von der „Unaussprechlichkeit des Individuellen“, um zu verdeutlichen, was mit ersterer nicht gemeint ist (7.). Diese Diskussion führt zu ontologischen Überlegungen über Individualität, Einzigkeit und haecceitas (8.). Schließlich bringe ich den Gedanken ins Spiel, daß wir in der natürlichen Sprache beliebig feine semantische Unterscheidungen treffen können, der auf den ersten Blick in einer gewissen Spannung zur These der deskriptiven Unerschöpflichkeit steht. Diese Spannung werde ich unter (9.) und (10.) zu mildern suchen und dabei meinen Begriff der ontischen Dichte zu Goodmans Begriff der semantischen Dichte in Beziehung setzen. (shrink)

In our paper we investigate a difficulty arising when one tries to reconsiliateessentialis t’s thinking with classification practice in the biological sciences. The article outlinessome varieties of essentialism with particular attention to the version defended by Brian Ellis. Weunderline the basic difference: Ellis thinks that essentialism is not a viable position in biology dueto its incompatibility with biological typology and other essentialists think that these two elementscan be reconciled. However, both parties have in common metaphysical starting point and theylack explicit (...) track of methodological procedures. Methodological inquiry involves less demandingassumptions than metaphysical, and therefore it is justified to analyse abovementioned discrepancy between Ellis and other essentialist in this context. We do it by bottom-up investigation whichfocuses on the practice of taxonomists in the particular field of biology. A case study helps us todiscover four characteristics of biological typology practice: impossibility of algorithmization,relativity, subjectivity and conventionality. These features prove non-realistic and therefore anti-essentialistic character of biological classification. We conclude by saying that any essentialismrelated to the notion of biological kind cannot be regarded as justified by scientific enterprise of creating typologies. (shrink)

If quantum mechanics (QM) is to be taken as an atomistic theory with the elementary particles as atoms (an ATEP), then the elementary particlcs must be individuals. There must then be, for each elementary particle a, a property being identical with a that a alone has. But according to QM, elementary particles of the same kind share all physical properties. Thus, if QM is an ATEP, identity is a metaphysical but not a physical property. That has unpalatable consequences. Dropping the (...) assumption that QM is an ATEP makes it possible to replace the assumption that elementary particles are individuals with the assumption that there are various kinds of elementary stuff that have smallest quantities — the smallest quantity of light, for example, is a photon. The problems about identity disappear, and the explanatory virtues of an ATEP are maintained. (shrink)
