Many predicates are dispositional. Some show this by a suffix like "-ible", -uble", or "-able": sugar is soluble in water, gasoline is flammable. Others have no such suffix and don't wear their dispositionality on their sleeves. Yet part of what it is to be solid is to be disposed to resist deformation, and part of what it is to be red is to appear red to normal human observers in normal lighting conditions. However, there is no agreement as to whether (...) dispositional predicates may be given a realist interpretation. For many authors, propositions containing them are made true by states of affairs (or facts) containing categorical, rather than dispositional properties. Many also claim that the states of affairs that make true attributions of dispositions to macroscopic objects are microscopic states of affairs concerning their parts. For example, what makes a vase fragile is the microscopic structure of its molecular constituents, which is what makes the vase break when it falls. Against these claims, I will argue that what makes a dispositional predicate apply to an object, whether macroscopic or microscopic, whether in common sense or science, is the object's having what I will call a powerful property. If the object is macroscopic, it is another matter whether the property is microreducible. My reasons for supposing that these powerful properties exist are those for postulating theoretical properties generally: they unify existing explanations and suggest new ones. (shrink)

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.

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)

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)

Strong emergentists about mental properties of conscious experience typically hold that these are ontologically “over and above” and distinct in kind as compared to physical properties. Powers-based account of strong emergence offer a promising framework for elucidating the ontological “over and above”-ness of strongly emergent properties. However, they do not automatically ensure the desired non-physicality. In this paper, I argue that a conception of properties as powerful qualities has in-built resources for capturing both the ontological “over (...) and above”-ness and the kind distinctness in a unified way. I begin by illustrating powers-based accounts of strong emergence. Then I defend the superiority of a powerful qualities-based account of strong emergence over two standard approaches recovering the distinctness in kind of strongly emergent mental properties: the via negativa strategy, and the anti-materialist strategy. I conclude that a conception of powerful qualities is a surprising yet natural ally for the proponent of strongly emergent mental properties. (shrink)

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)

Laws of nature are merely expressions of the powers possessed by various kinds of things, and counterfactual conditionals are grounded in the powers and tendencies of the entities involved in the counterfactual supposition together with their counterfactual surroundings. There are two versions of Strong Powerism. One takes the truthmakers for causal laws to be universals (a 'Realist' version). The second takes the truthmakers for causal laws to be the particulars that fall under the laws (a 'Nominalist' version). This chapter focuses (...) on how Powerism compares to other views about the laws. Neo‐Humeism has the leanest metaphysical theory, since its class of fundamental truths includes no conditionals, laws of nature or attributions of power. Metaphysically, Nomism is burdened with a large number of brute necessities, linking laws with actual patterns of particular fact. The chapter talks about the causal theory of properties: causal structuralism. (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 paper is about the relation between two metaphysical topics: the nature of properties, and way the instantiation of a property is sometimes “realized in” something more fundamental. It is partly an attempt to develop further, but also to correct, my earlier treatments of these topics. In my published work on realization, including my book Physical Realization, I was at pains to insist that acceptance of my view about this does not commit one to the causal theory of (...) class='Hi'>properties I have defended in several places. I held that it commits one to the claim that within any given world, properties with the same causal profile are identical, but not to the requirement that a property must have the same causal profile in any world in which it can be instantiated. I now think that this was a mistake. There is an argument from the account of realization I have offered to the conclusion that, if physicalism is true, properties of macroscopic objects have their causal profiles essentially. In what follows I will present that argument.Along the way I will correct what now seem to me mistakes in my earlier presentationsof the account of realization. And I will conclude with an additional argument for the causal theory of properties, one that does not tie it to the assumption that physicalism is true or to my account of realization. (shrink)

Properties are powers, but not pure powers. A world comprising objects, properties of which are exclusively dispositional, like a purely relational world, is indistinguishable from an empty world. If there are such worlds, they are bad models for ours. Powers and qualities go hand in hand.

When is an ideal of a ring radical or prime? By examining its generators, one may in many cases definably and uniformly test the ideal’s properties. We seek to establish such definable formulas in rings of p-adic power series, such as $\mathbb Q_{p}\langle X\rangle $, $\mathbb Z_{p}\langle X\rangle $, and related rings of power series over more general valuation rings and their fraction fields. We obtain a definable, uniform test for radicality, and, in the one-dimensional case, for (...) primality. This builds upon the techniques stemming from the proof of the quantifier elimination results for the analytic theory of the p-adic integers by Denef and van den Dries, and the linear algebra methods of Hermann and Seidenberg.prepared by Madeline G.

This paper develops and defends a compound powerful qualities view of properties. According to this view, properties are essentially composed of distinct powerful and qualitative elements. First, I outline an argument for the compound powerful qualities view, based on the claim that it has the explanatory power of other views, without incurring their costs. Second, I argue that the view has the resources to explain how properties are individuated, by claiming that properties are partially individuated (...) by their qualitative elements, and partially by their powerful elements. Third, I distinguish two versions of the view, one of which says that the qualitative and powerful are parts of properties, the other of which says that they are aspects of properties. I argue that the parthood view is the more parsimonious because it can avoid postulating a novel metaphysical relation. Fourth, I argue that the relation between the powerful and qualitative elements of a property is necessary, and lay out various viable options concerning what the relation might be, including grounding and primitivism.

“Strong AI” is the view that it is possible for an artificial agent to be mentally indistinguishable from human agents. Because the behavioral dispositions of artificial agents are determined by underlying dispositional systems, Strong AI seems to entail human behavioral dispositions are also determined by dispositional systems. It is, however, highly intuitive that non-dispositional, phenomenal properties, such as being in pain, at least partially determine certain human behavioral dispositions, like the disposition to take a pain killer. Consequently, Strong AI (...) seems to conflict with an intuitive view of phenomenal properties’ role in determining human behavioral dispositions. My goal here is not directly to evaluate this tension, but rather to clarify how dispositionalism in the metaphysics of properties bears on it. While a tempting thought is that dispositionalism fits well with Strong AI’s thoroughly dispositional account of human behavior, I argue that this thought does not hold for dispositionalism in general. In particular, I argue that combining a version of the “powerful qualities view” with certain dispositionalist conceptions of the will leads to a version of the intuitive view of phenomenal properties that is radically incompatible with Strong AI. I argue further that this view also raises a challenge for the weaker claim that an artificial agent could be behaviorally indistinguishable from a human agent. (shrink)

This paper examines the need for static dispositions within the basic ontology of the powers view of properties. To lend some focus, Neil Williams’s well developed case for static dispositions is considered. While his arguments are not necessarily intended to address fundamental ontology, they still provide a useful starting point, a springboard for diving into the deeper metaphysical waters of the dispositionalist approach. Within that ontological context, this paper contends that Williams’s arguments fail to establish the need to posit (...) static dispositions, or at least any sort not already well appreciated by advocates of the powers view. The paper then proceeds to suggest an alternative motivation for positing static dispositions, the success of which depends greatly on which ontological approach to objects is paired with the powers view.

Do determinable properties such as colour, mass, and height exist in addition to their corresponding determinates, being red, having a mass of 1 kilogram, and having a height of 2 metres? Optimists say yes, pessimists say no. Among the latter are Carl Gillett and Bradley Rives who argue that optimism leads to systematic overdetermination of causal powers and hence should be rejected on the grounds that the position is ontologically unparsimonious. In this paper I defend optimism against this charge (...) by showing that overdetermination of causal powers cannot plausibly be avoided when grounding what I call joint powers. It is therefore not clear why the optimist should be worried about the overdetermination of causal powers that follows from positing determinable properties. (shrink)

In debates about the metaphysics of properties, many have claimed that properties are powers. According to the powers view, a property's nature disposes objects to behave in certain ways in response to certain stimuli. For example, the property of fragility disposes objects to smash when a force is applied to them. But how should we understand powers? There has recently been a surge of interest in the powerful qualities view of properties. Other views in the field either (...) claim that properties are pure powers, or that they are qualities. The powerful qualities view rejects this dichotomy, saying that properties are both powers and qualities. In this paper, I distinguish some versions of the powerful qualities view, and some of the reasons to hold it. I also outline one of the most exciting elements of the view, which is its relation to the philosophy of mind. (shrink)

According to the subset account of realization, a property, F, is realized by another property, G, whenever F is individuated by a non-empty proper subset of the causal powers by which G is individuated (and F is not a conjunctive property of which G is a conjunct). This account is especially attractive because it seems both to explain the way in which realized properties are nothing over and above their realizers, and to provide for the causal efficacy of realized (...) properties. It therefore seems to provide a way around the causal exclusion problem. There is reason to doubt, however, that the subset account can achieve both tasks. The problem arises when we look closely at the relation between properties and causal powers, specifically, at the idea that properties confer powers on the things that have them. If realizers are to be ontically prior to what they realize, then we must regard the conferral of powers by properties as a substantive relation of determination. This relation of conferral is at the heart of a kind of exclusion problem, analogous to the familiar causal exclusion problem. I argue that the subset account cannot adequately answer this new exclusion problem, and is for that reason ill-suited to be the backbone of a non-reductive physicalism. (shrink)

In spite of the analogies between Q p and F p ((t)) which became evident through the work of Ax and Kochen, an adaptation of the complete recursive axiom system given by them for Q p to the case of F p ((t)) does not render a complete axiom system. We show the independence of elementary properties which express the action of additive polynomials as maps on F p ((t)). We formulate an elementary property expressing this action and show (...) that it holds for all maximal valued fields. We also derive an example of a rather simple immediate valued function field over a henselian defectless ground field which is not a henselian rational function field. This example is of special interest in connection with the open problem of local uniformization in positive characteristic. (shrink)

Dispositionalists maintain that the essence of a property is determined by the powers it confers upon its bearers and, as a result, that there is a necessary connection between properties and their powers. Contingentists, in contrast, maintain that the connection is contingent. The ability to conceive of a property as failing to confer some of its powers is often cited as an objection against dispositionalism. The standard dispositionalist response to this objection is to redescribe the imagined scenario so that (...) it no longer serves as a threat. Using the literature on phenomenal concepts as inspiration, I develop a new defense of dispositionalism that echoes Brian Loar's (1990) response to conceivability arguments against physicalism. Not only can Loar's general strategy be usefully applied to this new context, there is a sense in which that strategy works better here than it does in the original context in which Loar deployed it.

What has the dispositional analysis of properties and laws (e.g. Molnar, Powers, Oxford University Press, Oxford, 2003; Mumford, Laws in nature, Routledge London, 2004; Bird, Nature’s metaphysics, Clarendon Press, Oxford, 2007) to offer to the scientific understanding of physical properties?—The article provides an answer to this question for the case of spacetime points and their metrical properties in General Relativity. The analysis shows that metrical properties are not ‘powers’, i.e. they cannot be understood as producing the (...) effects of spacetime on matter with metaphysical necessity. Instead they possess categorical characteristics which, in connection with specific laws, explain those effects. Thus, the properties of spacetime do not favor the metaphysics of powers with respect to properties and laws. (shrink)

The aim of this paper is to argue that there are categorical properties as well as causal powers, and that the world would not exist as we know it without them. For categorical properties are needed to define the powers—to locate them, and to specify their laws of action. These categorical properties, I shall argue, are not dispositional. For their identities do not depend on what they dispose their bearers to do. They are, as Alexander Bird would (...) say, ’quiddities’. But there is nothing wrong with quiddities. And, in the second half of this paper, I shall defend the thesis that all categorical properties are quiddities. (shrink)

From a pre-publication review by the late Austrian economist, Don Lavoie, of George Mason University: -/- "The book's radical re-interpretation of property and contract is, I think, among the most powerful critiques of mainstream economics ever developed. It undermines the neoclassical way of thinking about property by articulating a theory of inalienable rights, and constructs out of this perspective a "labor theory of property" which is as different from Marx's labor theory of value as it is from neoclassicism. It traces (...) roots of such ideas in some fascinating and largely forgotten strands of the history of economics. It draws attention to the question of "responsibility" which neoclassicism has utterly lost sight of. It is startlingly fresh in its overall approach, and unusually well written in its presentation. ... It constitutes a better case for its economic democracy viewpoint than anything else in the literature." . (shrink)

Whilst the concept of causal powers is central to much post-positivist social science in general, and to critical realism in particular, it has not been significantly developed by critical realists since the initial work of Harré and Madden and Bhaskar in the mid-1970s. To deepen our understanding of powers we need to start with a ‘package’ of related terms. In §1 of the paper I introduce this package, clear up some terminological ambiguity and inconsistency, and focus the discussion upon things, (...) properties and powers. The real problems begin when we try to figure out how things, properties and powers relate to one another. In §2 I introduce and evaluate three possible ontologies: an ontology where powers are primary; an ontology where properties are primary; and an ontology where neither properties, powers are primary, but all emerge to form a unity. The last ontology is defended. §3 deals with ambiguities surrounding three other terms that often crop up when discussing powers, namely, dispositional properties, transfactuals and processes. The net result is a far less ambiguous concept of powers, firmly anchored in an ontology of things, properties and powers as a unity. (shrink)

This paper argues that Twin Earth twins belong to the same psychological natural kind, but that the reason for this is not that the causal powers of mental states supervene on local neural structure. Fodor’s argument for this latter thesis is criticized and found to rest on a confusion between it and the claim that Putnamian and Burgean type relational psychological properties do not affect the causal powers of the mental states that have them. While it is true that (...) Putnamian and Burgean type relational psychological properties do not affect causal powers, it is false that no relational psychological properties do. Examples of relational psychological properties that do affect causal powers are given and psychological laws are sketched that subsume twins in virtue of them instantiating these relational properties rather than them sharing the narrow contents of their thoughts.

This Article explores the rule of law aspects of the intersection between intellectual property and antitrust law. Contemporary discussions and debates on intellectual property, antitrust, and the intersection between them are typically framed in economically oriented terms. This Article, however, shows that there is more law in law than just economics. It demonstrates how the rule of law has influenced the development of several IP doctrines, and the interface between IP and antitrust, in important, albeit not always acknowledged, ways. In (...) particular, it argues that some limitations on IP rights, such as exhaustion and limitations on tying arrangements, are grounded in rule of law principles restricting the arbitrary exercise of legal power, rather than solely in considerations of economic efficiency. The historical development of IP law has reflected several tensions, both economic and political, that lie at the heart of the constitutional order of the modern state: the tension between the benefits of free competition and the recognition that some restraints on competition may be beneficial and justified; the concern that power, even when conferred in the public interest, can often be abused and arbitrarily.

What is an epiphenomenal property? This question needs to be settled before we can decide whether higher-level properties are epiphenomenal or not. In this paper, I offer an account of what it is for a property to have some causal power. From this, I derive a characterisation of the notion of an epiphenomenal property. I then argue that physically realized higher-level properties are not epiphenomenal because laws of nature impose causal similarities on the bearers of such (...) class='Hi'>properties, and these similarities figure as powers in the causal profiles of these properties.

This paper proposes a roughly Aristotelian account of powers ontology. In doing so, the paper uses the distinction found in Aristotle between four analogous senses of potency to explain causation and the existence-essence distinction in substances. On this basis, the paper offers some justification in support of the claims that powers and dispositions are the truth-makers of categorical properties and that categorical properties are ontologically dependent upon powers and dispositions.

Over the last century, many philosophers have argued in favour of a liberal-egalitarian accommodation of capitalism, in which the liberty of the market is to be combined with an egalitarian distribution of property. Theorists of positive freedom, amongst others, have been prominent in arguing for the liberal-egalitarian accommodation. They have argued that an egalitarian distribution of private property is necessary to give every citizen equal positive freedom. To lead an autonomous life, every citizen needs control over some private property. The (...) liberal-egalitarian accommodation to capitalism has come under threat in the last decades, as documented by a renewed widening of inequalities in wealth and income. In this essay, I will argue that this predicament requires us to look at one important precondition of the positive freedom argument. This precondition I call the de-politization of private property. Private property is conceived of as a purely private phenomenon, which has no effects on the exercise of political power. However, whether this precondition is met is a contingent matter; and so defenders of the positive freedom argument therefore need to turn their attention to the problem posed by the relation between private property and political power.

This thesis concerns the relation between the fundamental properties and the powers they confer. The views considered are introduced in terms of their acceptance or rejection of the quiddistic thesis. Essentially the quiddistic thesis claims that properties confer the powers they do neither necessarily nor sufficiently. Quidditism is the view that accepts the quiddistic thesis. The other two views to be considered, the pure powers view and the grounded view reject the quiddistic thesis. The pure powers view supports (...) its denial of the quiddistic thesis with the claim that properties consist in conferring the powers they do; the possession of a property just is the possession of a power. The grounded view, the positive view of this thesis, rejects the idea that properties are constituted by conferring the causal powers they do. Rather on the grounded view, it is the natures of the fundamental properties that metaphysically explain why they confer the powers they do. (shrink)

This chapter engages with Roger Cotterrell's characterisation of the trust as 'ideological.' However, rather than agreeing with Cotterrell that the trust disguises the true ownership of the beneficiary, it shows that the family trust subverts this idea of a one-sided ownership relation altogether by effecting a reversal in the hierarchical distinction between persons and things. Under the appearance of wealth, beneficial owners are serving the very things they own by ensuring their protection and continuous reproduction.

The system-property or ‘cybernetic’ theory of goals and goal-directedness became popular in the twentieth century. It is a theory that has reductionist and behaviourist roots. There are reasons to think that the system-property theory needs to be formulated in terms of counterfactuals. However, it proves to be difficult to formulate a counterfactual analysis of goal-directedness that is counterexample-free, non-circular, and non-trivial. These difficulties closely mirror those facing reductionists about dispositions, though the parallels between the two debates have been overlooked in (...) the literature. After outlining those parallels, the paper considers what goal theorists might learn from the dispositions debate. In particular, the paper discusses the need for a realist, non-reductionist account of goal-directedness, and explores the idea that properties of goal-directedness are themselves dispositions or ‘powers’ of a certain sort.

While the phrase "metaphysics of science" has been used from time to time, it has only recently begun to denote a specific research area where metaphysics meets philosophy of science—and the sciences themselves. The essays in this volume demonstrate that metaphysics of science is an innovative field of research in its own right. The principle areas covered are: The modal metaphysics of properties: What is the essential nature of natural properties? Are all properties essentially categorical? Are they (...) all essentially dispositions, or are some categorical and others dispositional? Realism in mathematics and its relation to science: What does a naturalistic commitment of scientific realism tell us about our commitments to mathematical entities? Can this question be framed in something other than a Quinean philosophy? Dispositions and their relation to causation: Can we generate an account of causation that takes dispositionality as fundamental? And if we take dispositions as fundamental, what is the ontological ground of dispositions? Pandispositionalism: Could all properties be dispositional in nature? Natural kinds: Are there natural kinds, and if so what account of their nature should we give? For example, do they have essences? Here we consider how these issues may be illuminated by considering examples from reals science, in particular biochemistry and neurobiology. (shrink)

We contribute to the study of generalizations of the Perfect Set Property and the Baire Property to subsets of spaces of higher cardinalities, like the power set ${\mathcal {P}}({\lambda })$ of a singular cardinal $\lambda $ of countable cofinality or products $\prod _{i<\omega }\lambda _i$ for a strictly increasing sequence $\langle {\lambda _i}~\vert ~{i<\omega }\rangle $ of cardinals. We consider the question under which large cardinal hypothesis classes of definable subsets of these spaces possess such regularity properties, focusing (...) on rank-into-rank axioms and classes of sets definable by $\Sigma _1$ -formulas with parameters from various collections of sets. We prove that $\omega $ -many measurable cardinals, while sufficient to prove the perfect set property of all $\Sigma _1$ -definable sets with parameters in $V_\lambda \cup \{V_\lambda \}$, are not enough to prove it if there is a cofinal sequence in $\lambda $ in the parameters. For this conclusion, the existence of an I2-embedding is enough, but there are parameters in $V_{\lambda +1}$ for which I2 is still not enough. The situation is similar for the Baire property: under I2 all sets that are $\Sigma _1$ -definable using elements of $V_\lambda $ and a cofinal sequence as parameters have the Baire property, but I2 is not enough for some parameter in $V_{\lambda +1}$. Finally, the existence of an I0-embedding implies that all sets that are $\Sigma ^1_n$ -definable with parameters in $V_{\lambda +1}$ have the Baire property. (shrink)

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

For Aquinas the vegetative powers of the soul (viz. nutrition, growth, and reproduction) are properties of living organisms: that is, they are characteristics of living organisms which, while not being essential characteristics, can nevertheless be predicated necessarily and convertibly of living organisms. Furthermore, they are active powers in the sense that they are capacities to perform certain actions which can have effects. But such and interpretation of Aquinas leads to the conceptual difficulty of allowing for the possibility of non-active (...) living organisms (i.e., organisms which do nothing). This difficulty can be avoided if we consider at least one of the vegetative powers as being a capacity which is of necessity always exercised, and this not because of what it is, but because of what it is related to. Thus, on this interpretation, all living organisms perform at least one action by consequence of their necessary relation to an end. (shrink)

One influential approach to environmental problems holds that their solution requires the definition of full liberal property rights over goods that will enable their value to be registered in actual or hypothetical markets. How adequate is that solution? In this paper I offer reasons to be sceptical, by placing recent liberal arguments in the context of older debates about property, in particular those concerned with the distribution of care. Although proposals for the extension of liberal property rights over environmental goods (...) often appeal to arguments from the need to distribute care, I show that there are conflicts between them. Care for particular places that embody the life of a community that has an existence over time is often expressed through resistance to liberal property rights. We express mutual obligations to members of a community through a denial of exclusive property rights over certain common goods. Also, what constitutes care for environmental goods itself is contested across class, occupation, culture, and history. Conflicts between those with different conceptions of care are often expressed through conflicts in property rights. The justification of property rights by appeal to particular accounts of proper care has, from the time of Locke to the present, been invoked to legitimate the appropriation of goods. The introduction and maintenance of liberal property-rights regimes involves the creation and sustenance of a particular distribution of social power, and should be understood as such. (shrink)

This research is conducted by the Intellectual Property and Policy Research Group at the W. Maurice Young Centre for Applied Ethics at the University of British Columbia. It is part of the GE3LS component of the Genome Canada Project "Dissecting Gene Expression Networks in Mammalian Organogenesis," MORGEN, which is located principally at the British Columbia Cancer Agency, Vancouver, British Columbia, Canada. The project is involved in upstream, basic genomic research. Part of this work includes the characterization of gene regulatory mechanisms (...) governing organogenesis with a special focus on the heart, liver and pancreas. This paper serves as an introduction to both the MORGEN case study and the role of alternative mechanisms, such as open source. We discuss interim research results as they relate to our broader study of the relationship between open science, commercialization and technology transfer offices. The role of technology transfer offices is central to our analysis and is viewed as a key factor in implementing Genome Canada policies and principles associated with IP and commercialization.

This paper examines the distinction drawn by Rawls between the ideas of property-owning democracy and welfare state capitalism, and assesses the strength of the support provided by justice as fairness for the implementation of the kinds of policies that distinguish property-owning democracy most sharply from welfare state capitalism. It is argued first that justice as fairness does not provide strong grounds for the implementation of policies designed to improve access to and broaden the distribution of nonhuman capital, arguably the most (...) important institutional feature of property-owning democracy. It is then argued that the idea of “highest-order interests” provides the basis upon which a powerful case for the implementation of this key policy type may be constructed. (shrink)

Jerry Fodor has long championed the view, recently dubbed “scientific intentional realism” (Loewer and Ray, 1991, p. xiv), that “a scientifically adequate psychology will contain laws that quantify over intentional phenomena in intentional terms.” On such a view our belief/desire psychology will be “vindicated” through empirical investigation; that is, it will be shown to denote the explanatory (or causally salient) states or events in the production of thought and behavior. That intentional properties, states, or events have causal efficacy---are not (...) mere epiphenomena---is necessary for any such vindication. This paper investigates whether intentional properties can if fact ground or sustain the causal relations empirical psychology aims to reveal. I conclude that intentional properties are not amenable to such an explanatory role, and that, therefore, a different vindication of intentional description is required of the realist. (shrink)

The paper describes a decidable class of verification problems expressed in first order timed logic. To specify programs we useState Machines. It is known that Abstract State Machines and first order timed logic are two very powerful formalisms apt to represent verification problems for timed distributed systems. However, the general verification problem represented in this way is undecidable. Prior, some decidable classes of verification problems were described in semantical properties that are in their turn undecidable. The decidable class of (...) the present paper is described in syntactical terms. Though it admits no functions, only predicates, it is of practical interest and we give an example illustrating possible applications. (shrink)

The fields K) of generalized power series with coefficients in a field K and exponents in an additive abelian ordered group G play an important role in the study of real closed fields. The subrings K) consisting of series with non-positive exponents find applications in the study of models of weak axioms for arithmetic. Berarducci showed that the ideal JK) generated by the monomials with negative exponents is prime when is the additive group of the reals, and asked whether (...) the same holds for any G. We prove that this is the case and that in the quotient ring K)/J, each element admits at least one factorization into irreducibles. (shrink)
