The property theory of musical works says that each musical work is a property that is instantiated by its occurrences, that is, the work's performances and playings. The property theory provides ontological explanations very similar to those given by its popular cousin, the type/token theory of musical works, but it is both simpler and stronger. However, type/token theorists often dismiss the property theory. In this essay, I formulate a version of the (...) class='Hi'>property theory that identifies each type (thus, each musical work) with a unique property. I then scrutinize the arguments offered for thinking that types, including musical works, are distinct from properties. I respond that no such argument is forceful and conclude that the property theory of musical works is superior to the type/token theory. (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 (...) 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).

In a lengthy review article, C. Anthony Anderson criticizes the approach to property theory developed in Quality and Concept (1982). That approach is first-order, type-free, and broadly Russellian. Anderson favors Alonzo Church’s higher-order, type-theoretic, broadly Fregean approach. His worries concern the way in which the theory of intensional entities is developed. It is shown that the worries can be handled within the approach developed in the book but they remain serious obstacles for the Church approach. The discussion (...) focuses on: (1) the fine-grained/coarse-grained distinction, (2) proper names and definite descriptions, (3) the paradox of analysis and Mates’ puzzle, and (4) the logical, semantical, and intentional paradoxes.

Property, or property rights, remains one of the most central elements in moral, legal, and political thought. It figures centrally in the work of figures as various as Grotius, Locke, Hume, Smith, Hegel and Kant. This collection of essays brings fresh perspective on property theory, from both legal and political theoretical perspectives, and is essential reading for anyone interested in the nature of property. Edited by two of the world's leading theorists of property, James (...) Penner and Michael Otsuka, this volume brings together essays which consider, amongst other topics, property and public law, the importance of legal forms in property theory, whether use or exclusion are most essential to our understanding of property, distributive justice, Lockean and Grotian theories, the common ownership of the Earth, and Confucian ideas of property.

Russell’s type theory has been the standard property theory for years, relying on rigid type distinctions at the grammatical level to circumvent the paradoxes of predication. In recent years it has been convincingly argued by Bealer, Cochiarella, Turner and others that many linguistic and ontological data are best accounted for by using a type-free property theory. In the spirit of exploring alternatives and “to have as many opportunities as possible for theory comparison”, this paper (...) presents another type-free property theory, to be called P*, intended for applications in Montague-style natural language semantics and formal ontology. The theory is philosophically grounded on Gupta’s and Belnap’s revision theory of definitions and its basic idea is viewing predication (exemplification) as a ‘circular concept’ that can be captured by circular definitions. The paper has the following fourteen sections: (1) Introduction; (2) Formal type-free property theory; (3) Applying RTD [revision theory of definitions] to exemplification; (4) The system P*; (5) Some features of P*; (6) A comparison with Turner’s system; (7) Entailment and P*; (8) P* and natural language semantics; (9) Noun phrases; (10) The need for type-freedom in semantics; (11) Arithmetic in P*; (12) Arithmetic in PN*; (13) Complexity of P*; (14) Conclusion, and acknowledgments.

The property theory of musical works is the view that identifies works of music with properties as universals. The purpose of this paper is to distinguish different versions of the property theory and argue that none of them can satisfy certain demands we expect from a successful theory of musical works. I conclude that although properties as universals are familiar and useful in other domains, we cannot rely on them to explain the ontological nature of (...) musical works. (shrink)

The paper reviews the empirical evidence for highly significant variation across perceivers in hue perception and argues that color physicalism cannot accommodate this variability. Two views that can accommodate the individual differences in hue perception are considered: the self-locating property theory, according to which colors are self-locating properties, and color relationalism, according to which colors are relations to perceivers and viewing conditions. It is subsequently argued that on a plausible rendition of the two views, the self-locating theory (...) has a slight advantage over color relationalism in being truer to the phenomenology of our color experiences.

This book explains China's intellectual property perspective in the context of European theories, through a critical examination of intellectual property theory and practice focused on China's compliance with the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). The author's critical review of contemporary intellectual property philosophy suggests that justifying intellectual property protection through Locke or Hegel's property theories internalizes a theoretical paradox. "Professor Wenwei Guan's treatment of intellectual property law and practice (...) in the PRC offers new perspectives that enrich an already active field of study. This book will be a useful contribution to academic and policy discourses examining conceptual and operational dimensions of China's intellectual property protection system and the broader process of China's international engagement." - Dr. Pitman B. Potter, Professor of Law, University of British Columbia, Canada "Dr. Guan reminds us of the daunting challenge of the public-private divide in forming and reforming TRIPS regime; how this regime has failed to address development needs and public concerns in developing countries like China; and how TRIPS's 'birth defect' can be overcome and its evolution can be put back on the right track." - Dr. Yahong Li, Associate Professor at Faculty of Law, Hong Kong University.

ABSTRACT Two rival approaches to property rights dominate contemporary political philosophy: Lockean natural rights and egalitarian theories of distributive justice. This article defends a third approach, which can be traced to the work of David Hume. Unlike Lockean rights, Humean property rights are not grounded in pre-institutional moral entitlements. In contrast to the egalitarian approach, which begins with highly abstract principles of distributive justice, Humean theory starts with simple property conventions and shows how more complex institutions (...) can be justified against a background of settled property rights. Property rights allow people to coordinate their use of scarce resources. For property rules to serve this function effectively, certain questions must be considered settled. Treating existing property entitlements as having prima facie validity facilitates cooperation between people who disagree about distributive justice. Lockean and egalitarian theories endorse moral claims that threaten to unsettle property conventions and undermine social cooperation. (shrink)

The property theory of content takes the content of each cognitive attitude (each belief, desire, and so on) to be a property to which the subject of the attitude is related in the appropriate psychological way. This view is motivated by standard cases of de se belief and other attitudes. In this paper, I consider a couple of related objections to the property theory of content. Both objections have to do with the possible non-existence of (...) the subject. More specifically, the objections are based on attitudes, the contents of which entail the non-existence of their subjects, and also on attitudes that commit their subjects to preferences regarding situations in which the subjects do not exist. I show that the property theory can answer these objections adequately, and I argue that my answer to the objections is more plausible than other possible responses. (shrink)

This book surveys the leading modern theories of property - Lockean, libertarian, utilitarian/law-and-economics, personhood, Kantian and human flourishing - and then applies those theories to concrete contexts in which property issues have been especially controversial. These include redistribution, the right to exclude, regulatory takings, eminent domain and intellectual property. The book highlights the Aristotelian human flourishing theory of property, providing the most comprehensive and accessible introduction to that theory to date. The book's goal is (...) neither to cover every conceivable theory nor to discuss every possible facet of the theories covered. Instead, it aims to make the major property theories comprehensible to beginners, without sacrificing accuracy or sophistication. The book will be of particular interest to students seeking an accessible introduction to contemporary theories of property, but even specialists will benefit from the book's lucid descriptions of contemporary debates.

The role of property theory as a framework for analysis and regulation of body parts has become a debate of topical importance because of the emergence of biomedical technologies that utilise body parts, and also because the application of the concept of property, even with respect to historically and traditionally accepted forms of property, raises serious challenges to the property analyst. However, there is another reason for the topicality of property in relation to body (...) parts: a proprietary approach confers on a claimant the advantage of continuing control that is tellingly lacking in non-property frameworks underpinned, for instance, by consent, negligence, privacy and unjust enrichment rules. In some circumstances, such as an unauthorised blood test performed on a blood sample obtained with consent, the continuing control provided by property law might be the only chance a claimant has to obtain a remedy. Economy of space, however, requires that only a prolegomenon on body parts and property theory is given below. Thus, the analysis begins by providing in outline a framework for comprehensive analysis of body parts within the realm of property theory; thereafter, the author engages with the normative question of whether body parts or rights exercisable over body parts could be admitted into the category of property.

This paper presents a type-free property-theoretic system in the spirit of a framework proposed by Menzel and then supplements it with a theory of truth and exemplification. The notions of a truth-relevantly complex (simple) sentence and of a truth-relevant subsentence are introduced and then used in order to motivate the proposed theory. Finally, it is shown how the theory avoids Russell's paradox and similar problems. Some potential applications to the foundations of mathematics and to natural language (...) semantics are sketched in the introduction. (shrink)

ABSTRACT In our response Field's ‘Properties, Propositions and Conditionals’, we explore the methodology of Field's program. We begin by contrasting it with a proof-theoretic approach and then commenting on some of the particular choices made in the development of Field's theory. Then, we look at issues of property identity in connection with different notions of equivalence. We close with some comments relating our discussion to Field's response to Restall’s [2010] ‘What Are We to Accept, and What Are We (...) to Reject, While Saving Truth from Paradox?’. (shrink)

The type-free property-theoretic system EC, based on the mediation view of predication, is presented. According to the mediation view, the copula or exemplification is a necessary component of every proposition. It is explained how the system EC relates to Bradley's Regress regarding predication. Finally, the system EC is applied to the Meinong-Russell debate on non-existent objects and it is shown how EC allows us to preserve some important intuitions of both Meinong and Russell.

This chapter is concerned with representing the semantics of natural language plurals and mass terms in property theory; a weak first-order theory of Truth, Propositions and Properties with fine-grained intensionality (Turner 1990, Turner 1992, Aczel 1980). The theory allows apparently coreferring items to corefer without inconsistency. This is achieved by using property modifiers which keep track of the property used to refer to a term, much like Landman’s roles (Landman 1989). We can thus predicate (...) apparently contradictory properties of “the judge” and “the cleaner,” for example, even if they turn out to be the same individual. The same device can also be used to control distribution into mereological terms: when we say “the dirty water is liquid,” we can infer that those parts that are dirty water are liquid without inferring that the dirt is liquid. The theory shows how we can formalise some aspects of natural language semantics without being forced to make certain ontological commitments. This is achieved in part by adopting an axiomatic methodology. Axioms are proposed that are just strong enough to support intuitively acceptable inferences, whilst being weak enough for some ontological choices to be avoided (such as whether or not the extensions of mass terms should be homogeneous or atomic). The axioms are deliberately incomplete, just as in basic PT, where incomplete axioms are used to avoid the logical paradoxes. The axioms presented are deliberately too weak to say much about ”non-denoting’ definite descriptors. For example, we cannot erroneously prove that they are all equal. Neither can we prove that predication of such definites results in a proposition. This means that we cannot question the truth of sentences such as “the present king of France is bald.”. (shrink)

For over a century, intellectual property regimes have been justified using Western philosophical theories rooted in the idea that IP must reward talent and maximize global stocks of knowledge and cultural products. Reframing IP in a context of legal pluralism, Ezieddin Elmahjub brings an Islamic and comparative narrative to the appropriate design and scope of IP rights, and in doing so criticizes the dominance of Western influence on a global regime that impacts the ability of people to access medicine, (...) to read, to imagine, and to reshape popular culture. The Islamic vision of IP, which is based on a broad theory of social justice, maintains that IP cannot simply be seen as a reward for effort or tool to maximize economic efficiency but as one legal right within a complicated distributive scheme affecting fundamental human rights, equal opportunities, and human capabilities.

Although John Locke’s theory of appropriation is undoubtedly influential, no one seems to agree about exactly what he was trying to say. It is unlikely that someone will write the interpretation that effectively ends the controversy. Instead of trying to find the one definitive interpretation of Locke’s property theory, this article attempts to identify the range of reasonable interpretations and extensions of Lockean property theory that exist in the contemporary literature with an emphasis on his (...) argument for unilateral appropriation. It goes through Locke’s argument point-by-point discussing the controversy over what he said and over what he perhaps should have said to make the most valuable and coherent argument. The result is an outline of Lockean theories of property: a menu of options by which one might use appropriation to justify property rights. Supporters only need to pick the version they find most plausible, but opponents should be aware of the entire menu. Anyone claiming to refute appropriation-based property rights must address not only one but all potentially valid versions of it. (shrink)

This paper extends the theory of situated inference from Mares to treat two weak relevant logics, B and DJ. These logics are interesting because they can be used as bases for consistent naïve theories, such as naïve set theory. The concepts of a situation and of information that are employed by the theory of situated inference are used to justify various aspects of these logics and to give an interpretation of the notion of set that is represented (...) in the naïve set theories that are based on them.

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.

We propose a theory for modeling concepts that uses the state-context-property theory (SCOP), a generalization of the quantum formalism, whose basic notions are states, contexts and properties. This theory enables us to incorporate context into the mathematical structure used to describe a concept, and thereby model how context influences the typicality of a single exemplar and the applicability of a single property of a concept. We introduce the notion `state of a concept' to account for (...) this contextual influence, and show that the structure of the set of contexts and of the set of properties of a concept is a complete orthocomplemented lattice. The structural study in this article is a preparation for a numerical mathematical theory of concepts in the Hilbert space of quantum mechanics that allows the description of the combination of concepts.

This book uses game theory to analyse the creation, evolution and function of economic and social institutions. The author illustrates his analysis by describing the organic or unplanned evolution of institutions such as the conventions of war, the use of money, property rights and oligopolistic pricing conventions. Professor Schotter begins by linking his work with the ideas of the philosophers Rawls, Nozick and Lewis. Institutions are regarded as regularities in the behaviour of social agents, which the agents themselves (...) tacitly create to solve a wide variety of recurrent problems. The repetitive nature of the problems permits them to be described as a recurrent game or 'supergame.' The agents use these regularities as informational devices to supplement the information contained in competitive prices. The final chapter explores the applicability of this theory, first by relating it to previous work on the theory of teams, hierarchies, and non-maximizing decision theory, and then by using it to provide a new approach to a variety of questions both within and outside economics.

Writers of very different persuasions have relied on arguments about self-ownership; in recent years, it is libertarians who have rested their political theory on self-ownership, but Grotian authoritarianism rested on similar foundations, and, even though it matters a good deal that Hegel did not adopt a full-blown theory of self-ownership, so did Hegel's liberal-conservatism. Whether the high tide of the idea has passed it is hard to say. One testimony to its popularity was the fact that G. A. (...) Cohen for a time thought that the doctrine of self-ownership was so powerful that an egalitarian like himself had to come to terms with it; but he has since changed his mind. I have tackled the topic of self-ownership glancingly elsewhere, but have not hitherto tried to pull together the observations I have made in passing on those occasions. The view I have taken for granted and here defend is that self-ownership is not an illuminating notion—except in contexts that are unattractive to anyone of libertarian tastes. (shrink)

Teoria własności intelektualnej Kennetha E. Himmy ma na celu uzasadnienie prawa naturalnego do intelektualnej "zawartości" dzieł sztuki i wynalazków. Uważa się przy tym dość powszechnie, że ową zawartość stanowią obiekty abstrakcyjne. Himma proponuje modyfikację znanego argumentu Johna Locke'a z uwzględnieniem koncepcji wartości. Utrzymuje, że nawet jeśli obiekty abstrakcyjne istnieją przed ich rzekomym "stworzeniem", to ich "konsumpcja" nie jest możliwa, dopóki wynalazca lub artysta nie wykona określonej pracy. Praca ta ma jego zdaniem być niezbędna dla zapewnienia dostępu do tychże obiektów. Himma (...) interpretuje ten akt jako "tworzenie wartości" które uzasadnia przyznanie wynalazcom i artystom praw własności intelektualnej. W niniejszej pracy założenia na których opiera się teoria Himmy poddane są krytycznej analizie. Argumentuje się, że ludzka praca nie może zwiększyć dostępności obiektów abstracyjnych oraz że pojęcie wartości nie ma do nich zastosowania. Spostrzeżenie to podważa zasadność proponowanej teorii. Ponadto rozważana jest zasadność postulowanych przez Himmę praw. Argumentuje się, że prawa te są niemożliwe do wyegzekwowania w odniesieniu do obiektów abstrakcyjnych i nie implikują praw do kontroli nad obiektami materialnymi. (shrink)

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.

The central claim of Kant's political philosophy is that rational agents sharing a territory can justifiably be forced to live under a state; they have, in Kant's words, a duty of right to leave the state of nature. Perhaps something along these lines is entailed by any theory of state legitimacy, but the point raises special difficulties for Kant. He believes that rational agents have a right to freedom; that is, he believes that a rational agent's external freedom - (...) her ability to set and pursue ends for herself without being subject to the choices of others - can justifiably be restricted only for the sake of external freedom itself. To establish that human beings can be forced to join a civil condition, it will therefore not do to show that the state promotes security, prosperity or any other such value: Kant has to show that human beings living side by side need a state to be free.

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.

The article argues that persons should be conceived as self-owners and entitled to acquire private property within justifiable property conventions because they should be able to live as project pursuers. This is the ‘project pursuit argument’. It leads to a conception of self-ownership that is stringent, but weaker than standard libertarian notions of self-ownership, and to an understanding of private property as a convention that has to meet a sufficientarian threshold in order to be justifiable.

In this short, clear and engaging book, Neil Feit defends the unorthodox view that the contents of beliefs and other cognitive attitudes are properties, and not, as is usually held, propositions. The core of his argument has to do with de se beliefs, beliefs about the self. Based on examples and arguments due to Perry , Lewis and Chisholm , along with considerations about internalism and physicalism, Feit offers a battery of arguments for the conclusion that the contents of de (...) se beliefs cannot be propositions and therefore must be properties. For reasons of uniformity and simplicity Feit then extends this conclusion to all beliefs. So, according to Feit, the content of the de se belief that I am a philosopher is the property of being a philosopher, and my having this belief consists in my self-ascribing this property. For de dicto beliefs, believing that p is self-ascribing the property of being such that p, and for de re beliefs, believing that x is F is self-ascribing the property of bearing some relation of acquaintance R to something that is F. For example, to have the de dicto belief that …. (shrink)

This essay argues that natural properties are all essentialists need to find a true friend in counterpart theory.

Section two establishes the connection between the natural properties counterpart theory needs and the essentialist consequences Lewis disavows. (...) Section three answers two objections: the first attempts to block the consequences of adding natural properties to counterpart theory; the second grants the consequences, but denies that they amount to essentialism. –Correspondence to: [email protected].

Despite many attempts to achieve an adequate definition of living systems by means of a set of necessary and sufficient conditions, the opinion that such an enterprise is inexorably destined to fail is increasingly gaining support. However, we believe options do not just come down to either having faith in a future success or endorsing skepticism. In this paper, we aim to redirect the discussion of the problem by shifting the focus of attention from strict definitions towards a philosophical framework (...) that allows conceiving of living systems as a natural kind, but whereby natural kinds are not to be defined by fixed necessary and sufficient conditions. We argue for a property-cluster kind approach according to which living systems constitute a natural kind with vague boundaries, capable of changing, and whose members do not need to instantiate every property. We draw from Boyd’s homeostatic property-cluster theory and introduce two modifications, one regarding homeostatic mechanisms and another related to the scientific role of kinds. Thus, our view overcomes some difficulties of Boyd’s theory and we are able to account for the natural kindhood of living things. We also emphasize the most appealing features of our approach for specific research fields and address three objections to this sort of approach. (shrink)

The point of departure of David Ellerman's paper is that the role of labour in economics can be looked at in a fundamentally different way than has typically been the case. The paper's purpose is, therefore, oppositional. However, it cannot simply be dismissed. It is clearly articulated, well reasoned, and most importantly, thought provoking. It requires one to rethink how one conceives some basic issues in economics. As such, one does not need to be entirely convinced by the argument to (...) consider it worthy of dissemination. At the same time, if one subscribes to the ethic of structured or critical pluralism one must also consider the pressure points of the argument (see Dow, 2004; Dobusch and Kapeller, 2012). Below, I briefly reconstruct Ellerman's core claims and provide some comment on that argument. Read David Ellerman's paper "The Labour Theory of Property and Marginal Productivity Theory". (shrink)

Typicality is routinely invoked in everyday contexts: bobcats are typically short-tailed; people are typically less than seven feet tall. Typicality is invoked in scientific contexts as well: typical gases expand; typical quantum systems exhibit probabilistic behaviour. And typicality facts like these support many explanations, both quotidian and scientific. But what is it for something to be typical? And how do typicality facts explain? In this paper, I propose a general theory of typicality. I analyse the notion of a typical (...) property. I provide a formalism for typicality explanations, and I give an account of why typicality explanations are explanatory. Along the way, I show how typicality facts explain a variety of phenomena, from everyday phenomena to the statistical mechanical behaviour of gases. Finally, I argue that typicality is not the same thing as probability. (shrink)

While it is a point of agreement in contemporary republican political theory that property ownership is closely connected to freedom as non-domination, surprisingly little work has been done to elucidate the nature of this connection or the constraints on property regimes that might be required as a result. In this paper, I provide a systematic model of the boundaries within which republican property systems must sit and explore some of the wider implications that thinking of (...) class='Hi'>property in these terms may have for republicans. The boundaries I focus on relate to the distribution of property and the application of types of property claims over particular kinds of goods. I develop this model from those elements of non-domination most directly related to the operation of a property regime: (a) economic independence, (b) limiting material inequalities, and (c) the promotion of common goods. The limits that emerge from this analysis support intuitive judgments that animate much republican discussion of property distribution. My account diverges from much orthodox republican theory, though, in challenging the primacy of private property rights in the realization of economic independence. The value of property on republican terms can be realized without private ownership of the means of production. (shrink)
