Aristotle’s philosophy is considered with respect to one central concept of his philosophy, viz. opposition. Far from being a mere side-effect of syllogistic, it is argued in the present paper that opposition helps to articulate ontology and logic through an account of what can be or cannot be in a systematic and structural way. The paper is divided into three main parts. In Section I, the notion of Being is scrutinized through Aristotle’s theory of categories. In Section II, the notion (...) of Non-Being is connected to Aristotle’s theory of oppositions. In Section III, the notion of essence is revisited in order to bring about a holist theory of meaning by individuating through opposite properties. In conclusion, the legacy of Aristotle is depicted as balanced between a powerful reflection around Being and a restrictive ontology of substance. (shrink)

Dispositionality and qualitativity are key notions to describe the world that we inhabit. Dispositionality is a matter of what a thing is disposed to do in certain circumstances. Qualitativity is a matter of how a thing is like. According to the Identity Theory of powers, every fundamental property is at once dispositional and qualitative, or a powerful quality. Canonically, the Identity Theory holds a contentious identity claim between a property’s dispositionality and its qualitativity. In the literature, this view faces a (...) contradiction objection that undermines its merits. We should therefore consider an alternative version that does not embrace the identity claim. My aim is to show that we can enjoy the benefits of the Identity Theory without embracing the identity between the dispositional and the qualitative. I shall argue that a distinction between two senses of dispositionality and qualitativity serves the purpose. I will then discuss three readings of the identity claim that can be formulated in light of such a distinction. I will conclude that even if the identity were to fail in any of the suggested readings, it would be possible to hold an account of fundamental powerful qualities. (shrink)

W artykule rozważana jest koncepcja nagiego substratu w kontekście problemu indywiduacji. Głównym celem tekstu jest obrona teorii nagiego substratu (TNS) przed klasycznymi oraz współczesnymi zarzutami. Tok rozważań jest następujący: Autor we wstępie definiuje problem jednostkowienia i systematyzuje obecną dyskusję nad tym zagadnieniem. Następnie skupia się na porównaniu teorii wiązki i teorii nagiego substratu, ujętych jako alternatywne wyjaśnienia jednostkowości przedmiotów. Celem porównania dwóch teorii jest przedstawienie motywacji stojących za przyjęciem TNS. Głównym elementem tekstu jest punkt 2, w którym analizuje podstawowe założenia (...) TNS oraz odpiera wytaczane wobec niej zarzuty. Autor wykazuje, że warunkiem możliwości przezwyciężenia zarzutów z przeludnienia i regresu jest modyfikacja TNS i postulat teorii identyczności.

There are striking similarities in the ways philosophers use to speak about concepts and properties. For example, it is commonly said that concepts and properties are ‘predicated’ of things – which, in turn, are said to ‘exemplify’ those concepts or properties. Concepts as well as properties are assumed to have ‘instances’ and ‘extensions’ and to be the semantical values of adjectives like ‘red,’ ‘round,’ and so on. Even metaphysically, concepts and properties seem to have much in common. Thus, both have (...) been characterized as universals capable of having multiple instances. In this essay, I would like to explore the conspicuous interrelations between concepts and properties from the viewpoint of a pragmatist approach which aims to explain phenomena of mind and meaning in terms of the actions and practices of (social) beings. To this end, I shall discuss the probably most influential development of this program, namely Wittgenstein’s theory of meaning as use, and probe the extent to which this theory is capable of illuminating the ontological nexus between concepts and properties.

A crucial question for both philosophy and for science concerns the kind of relationship that obtains between entities—objects, properties, states, processes, kinds and so on—that exist at apparently higher and lower ‘levels’ of reality. According to reductionism, seeming higher-level entities can in fact be fully accounted for by more fundamental, lower-level entities. Conversely, emergentists of various stripes hold that whilst higher-level entities depend in some important sense on lower-level entities, they are nevertheless irreducible to them. This introductory paper outlines the (...) context of the debate between emergentists and reductionists; offers a broad characterisation of ‘strong’ or ontological emergence, and provides summaries of each of the papers to come in this special issue.

What determines qualitative sameness and difference? This book explores four principal accounts of the ontological basis of properties, including universals, trope theory, resemblance nominalism, and class nominalism, considering the assumptions and ontolological commitments which are required to make each into a plausible account of properties. -/- The latter half of the book investigates the applications of property theory and the different conceptions of properties which might be adopted with these in mind: first, the possibility and desirability of individuating properties, and (...) the distinction between sparse and abundant conceptions of properties; second, the distinction between intrinsic and extrinsic properties; third, the relationship between properties and their causal powers, and whether this is necessary or contingent; fourth, the relationship between properties and causation, modality, and laws of nature; finally, whether properties exist objectively, and if they do, what our epistemic position is with respect to such entities.

Este ensaio consiste num exame crítico da estrutura e do valor de um conjunto diverso de argumentos por regressão ao infinito que têm sido objecto de discussão recorrente na metafísica contemporânea. O seminal livro de David Armstrong Nominalism and Realism (Armstrong 1978) contém uma das mais compreensivas discussões de argumentos regressivos em metafísica, os quais variam entre argumentos que foram de facto avançados ao longo da história da disciplina (como o Argumento do Terceiro Homem, de Platão) e argumentos construídos de (...) novo por Armstrong para fins de exame crítico. Os argumentos regressivos discutidos por Armstrong têm como alvo uma grande variedade de teorias metafísicas acerca da semelhança e da predicação, entre as quais se contam o nominalismo de predicados, o nominalismo de conceitos, o nominalismo de classes, o nominalismo de semelhança e o realismo metafísico.

Neste ensaio, discutem-se cinco questões acerca da existência: 1. É a existência representável em termos de quantificação? 2. É a existência um predicado" real", de primeira ordem? 3. É existir o mesmo que ser? 4. Existe tudo? 5. Qual é a forma lógica de afirmações de existência? São introduzidas e examinadas algumas das mais salientes posições acerca destas questões, em especial a concepção Frege-Russell da existência e diversas concepções recentes neo-Meinongianas. Defendemos as seguintes três teses acerca daquilo que deve ser (...) um bom predicado de existência:(a) um predicado puramente lógico e parcialmente definível em termos do quantificador existencial;(b) invariavelmente um predicado de primeira ordem (dadas certas suposições de partida acerca do universo do discurso);(c) um predicado universal, verdadeiro de tudo e falso de nada.

The concepts of particular and universal have grown so familiar that their significance has become difficult to discern, like coins that have been passed back and forth too many times, worn smooth so their values can no longer be read. On the Genealogy of Universals seeks to overcome our sense of over-familiarity with these concepts by providing a case study of their evolution during the late nineteenth century and early twentieth century, a study that shows how the history of these (...) concepts is bound up with the origins and development of analytic philosophy itself. Understanding how these concepts were taken up, transfigured, and given up by the early analytic philosophers, enables us to recover and reanimate the debate amongst them that otherwise remains Delphic. This book begins from the early, originating texts of analytic philosophy that have hitherto baffled commentators, including Moore's early papers, and engages afresh with the neglected contributions of philosophical figures that historians of analytic philosophy have mostly since forgotten, including Stout and Whitehead. This sheds new light upon the relationships of Moore to Russell, Russell to Wittgenstein, and Wittgenstein to Ramsey. (shrink)

This book aims to show the centrality of a proper ontology of properties in thinking about consciousness. Philosophers have long grappled with what is now known as the hard problem of consciousness, i.e., how can subjective or qualitative features of our experience—such as how a strawberry tastes—arise from brain states? More recently, philosophers have incorporated what seems like promising empirical research from neuroscience and cognitive psychology in an attempt to bridge the gap between measurable mental states on the one hand, (...) and phenomenal qualities on the other. In Consciousness and the Ontology of Properties, many of the leading philosophers working on this issue, as well as a few emerging scholars, have written 14 new essays on this problem. The essays address topics as diverse as substance dualism, mental causation, the metaphysics of artificial intelligence, the logic of conceivability, constitution, extended minds, the emergence of consciousness, and neuroscience and the unity and neural correlates of consciousness, but are nonetheless unified in a collective objective: the need for a proper ontology of properties to understand the hard problem of consciousness, both on non-empirical and empirical grounds.

It is widely accepted that if a property is essential then it is necessary. Against this I present numerous counterexamples from biology and chemistry, which fall into two groups: (I) A property is essential to a genus or species, yet some instances of this genus or species do not have this essential property. (II) A property is essential to a genus, yet some species of this genus do not have this essential property. I discuss and reject four minor objections. Then (...) I discuss in depth whether a distinction between constitutive essence and consequential essence is able to handle these counterexamples. I conclude that this distinction is better put as one between (1) the essence, which is necessary, and (2) the essential properties, which are not formally necessary. An essence of an object X is the substantial universal expressed by its real definition. An object X has a property P essentially iff the property P is explanatory and non-trivial, and P follows from the essence of X. (shrink)

An important challenge to color objectivists, who hold that statements concerning color are made true or false by objective 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 Noûs 50: 3–40),. In ), 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.

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.

Is property-awareness constituted by representation or not? If it were, merely being aware of the qualities of physical objects would involve being in a representational state. This would have considerable implications for a prominent view of the nature of successful perceptual experiences. According to naïve realism, any such experience—or more specifically its character—is fundamentally a relation of awareness to concrete items in the environment. Naïve realists take their view to be a genuine alternative to representationalism, the view on which the (...) character of such experiences is constituted by representation. But naïve realists must admit qualities or property instances as items of awareness if they are to remain wedded to common sense, and the nature of property-awareness may smuggle constitutive representation into the naïve realist account of character. I argue that whether property-awareness involves representation, and consequently whether naïve realism is distinct from representationalism or not, depends on what qualities are fundamentally. On universalist and nominalist accounts, property-awareness turns out to involve representation. Not so under tropism. (shrink)

In the paper a theory of relevant properties is developed. The theory permits us to distinguish between properties that are relevant to an object and the properties that are irrelevant to it. Predication is meaningful only if a property is relevant to an object. On the base of introducing a special negative type of predication as opposed to usual sentential negation, a new notion of generalization for properties is defined. Context-free, as weIl as context-depended relevance of properties are considered.

This paper takes up issues related to the notion of chemical substances arising from their mereological and modal features. Related notions are elements and compounds, into which substances are sub-divided, and the general notion of mixture, which as a special case might involve several substances, but covers other cases too. These are essentially macroscopic concepts. Some of the chemical arguments for this claim have been presented elsewhere. The present paper is a metaphysical treatment of matter as categorised by the major (...) chemical concepts bearing on distinctions between homogeneous and heterogeneous matter, and between a single and several substances.

This dissertation argues that we have no good reason to accept any one theory of properties as correct. To show this, I present three possible bases for theory-choice in the properties debate: coherence, explanatory adequacy, and explanatory value. Then I argue that none of these bases resolve the underdetermination of our choice between theories of properties. First, I argue considerations about coherence cannot resolve the underdetermination, because no traditional theory of properties is obviously incoherent. Second, I argue considerations of explanatory (...) adequacy cannot resolve the underdetermination, because every traditional theory of properties lacks the theoretical resources to adequately explain resemblance, causal powers, and predication. However, these inadequacies are easily remedied with theoretical modifications. But this results in an overabundance of modified, but adequate, theories of properties. Third, I argue explanatory virtues cannot resolve the underdetermination, because we have no reason to think explanatory virtues make theories of properties more likely to be true. I reject the common argument that explanatory virtues are truth-conducive in theories of properties because they are truth-conducive in scientific theories. Since none of the three bases for theory choice can resolve the underdetermination, I conclude that we have no good reason to accept any one theory of properties as correct. Finally, I consider the possibility of choosing one theory over the others on pragmatic grounds. But I argue that pragmatic grounds cannot resolve the underdetermination either. Instead, I suggest we accept the view I call 'instrumental pluralism,' which allows practitioners to use whatever theory of properties they find useful. Adviser: Jennifer McKitrick. (shrink)

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 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)

David Lewis’s arguments against magical ersatzism are notoriously puzzling. Untangling different strands in those arguments is useful for bringing out what he thought was wrong with not just one style of theory about possible worlds, but with much of the contemporary metaphysics of abstract objects. After setting out what I take Lewis’s arguments to be and how best to resist them, I consider the application of those arguments to general theories of properties and relations. The constraints Lewis motivates turn out (...) to yield an argument for concretism about possible individuals that is quite different from the better-known Lewisian arguments for that position. The discussion also touches on the puzzling question of whether things are the way they are because of the properties they have, or are the properties and relations the way they are because of the things that have them.

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.

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.

It has often been claimed that Locke’s agnostic remarks in the Essay represent his suspension of philosophical judgment on crucial ontological issues or his hesitation over which metaphysical stance to adopt. Against this often-raised criticism, I argue that Locke actually held a clear position—a type of functionalism about thingness in general, whether macro or micro, or whether mental or physical. What Locke refers to as a ‘nominal essence’, I further argue, represents a set of functional roles that a thing plays (...) in order to be classified as of a kind to which it belongs. Our empirical knowledge about things—confined to their nominal essences—can only tell us about their functional roles but not their intrinsic properties that realize those roles. One remains therefore incurably ignorant about the intrinsic property of things in themselves. I explore the historical and philosophical significance of Locke’s functional approach. (shrink)

A book review of "Properties" by Douglas Edwards (Polity Press, 2014).

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)

The existence of complex predicates seems to support an abundant conception of properties. Specifically, the application conditions for complex predicates seem to be explained by the distribution of a sparser base of predicates. This explanatory link might suggest that the existence and distribution of properties expressed by complex predicates are explained by the existence and distribution of a sparser base of properties. Thus, complex predicates seem to legitimize the assumption of a wide array of properties. The additional properties are no (...) explanatory addition to the sparse base. I argue, however, that construing complex predicates as expressing properties undermines the explanatory links between simple and complex predications. The argument explores a variety of accounts of complex predicates currently on offer and develops a number of themes from the work of Herbert Hochberg. (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.
