We investigate particular cosmological models, based either on tachyon fields or on perfect fluids, for which soft future singularities arise in a natural way. Our main result is the description of a smooth crossing of the soft singularity in models with an anti-Chaplygin gas or with a particular tachyon field in the presence of dust. Such a crossing is made possible by certain transformations of matter properties. We discuss and compare also different approaches to the problem of crossing of (...) the Big Bang–Big Crunch singularities. (shrink)

ArgumentEighteenth-century Montpellerian vitalism and contemporaneous French “vitalist” materialism, exemplified by the medical and biological materialism of La Mettrie and Diderot, differ in some essential aspects from some later forms of vitalism that tended to postulate immaterial vital principles or forces. This article examines the arguments defending the existence of vital properties in living organisms presented in the context of eighteenth-century French materialism. These arguments had recourse to technological metaphors and analogies, mainly clockworks, in order to claim that just as machines (...) can have functional properties which its parts do not possess, so living organisms can, as material entities, also have organic or vital properties which its material parts do not possess. Such arguments, with the help of a healthy dose of epistemological scepticism, tend to strike a balance between two positions concerning the ontology of life which we now tend to label “vitalism” and “emergentism.” Although there is nothing inconsistent in viewing vital properties as emergent, some ambiguity results if one does not draw a clear distinction between properties and functions. The philosophical problems related to these ambiguities are revealed in Diderot's apparent hesitation concerning sentience as “a general property of matter or the product of organization.”. (shrink)

Are property rights absolute? This paper attempts to reframe this question by drawing on insights from the field of social ontology. My main claim is that, even if we accept the most extreme view of the absoluteness of property rights, there are some non-normative conceptual limitations to these rights. The conceptual limitations are based on two claims about the nature of property rights and their subject matter, namely objects in the world: (1) property law regulates relations between persons through (...) the use of objects, and not relations between persons and objects; (2) even when owned, objects retain some of their ‘independent’, unowned, existence. Taken together, these claims confine property law to the institutional meaning that is given to objects, which is distinct from their social and natural meanings. Since property law defines objects in a certain way, it makes space for other social considerations but without the need to qualify property rights. (shrink)

I analyze the meaning of mass in Newtonian mechanics. First, I explain the notion of primitive ontology, which was originally introduced in the philosophy of quantum mechanics. Then I examine the two common interpretations of mass: mass as a measure of the quantity of matter and mass as a dynamical property. I claim that the former is ill-defined, and the latter is only plausible with respect to a metaphysical interpretation of laws of nature. I explore the following options for (...) the status of laws: Humeanism, primitivism about laws, dispositionalism, and ontic structural realism. (shrink)

The origin of the wave properties of matter is discussed from the point of view of stochastic electrodynamics. A nonrelativistic model of a charged particle with an effective structure embedded in the random zeropoint radiation field reveals that the field induces a high-frequency vibration on the particle; internal consistency of the theory fixes the frequency of this jittering at mc2/ħ. The particle is therefore assumed to interact intensely with stationary zeropoint waves of this frequency as seen from its proper (...) frame of reference; such waves, identified here as de Broglie's phase waves, give rise to a modulated wave in the laboratory frame, with de Broglie's wavelength and phase velocity equal to the particle velocity. The time-independent equation that describes this modulated wave is shown to be the stationary Schrödinger equation (or the Klein-Gordon equation in the relativistic version). In a heuristic analysis appled to simple periodic cases, the quantization rules are recovered from the assumption that for a particle in a stationary state there must correspond a stationary modulation.Along an independent and complementary line of reasoning, an equation for the probability amplitude in configuration space for a particle under a general potential V(x) is constructed, and it is shown that under conditions derived from stochastic electrodynamics it reduces to Schrödinger's equation. This equation reflects therefore the dual nature of the quantum particles, by describing simultaneously the corresponding modulated waveand the ensemble of particles. (shrink)

Usually a relational approach, such as one appealing to care or love, is contrasted with an account of justice. In this chapter, however, I argue that distributive justice is well conceived as itself a matter of honouring people in virtue of their capacity to love and to be loved. After spelling out a familiar conception of love, I explain how treating people with respect in light of this capacity provides a plausible basis for human rights, one that rivals influential (...) individualist foundations such as Kantian respect for autonomy and Catholic honor of human life. I also articulate an egalitarian conception of how to allocate wealth that I argue is also a function of treating people's ability to love as special and that can compete against views salient in Anglo-American political philosophy such as cost-benefit analysis and John Rawls’ difference principle.

Sensibility, in any of its myriad realms – moral, physical, aesthetic, medical and so on – seems to be a paramount case of a higher-level, intentional property, not a basic property. Diderot famously made the bold and attributive move of postulating that matter itself senses, or that sensibility (perhaps better translated ‘sensitivity’ here) is a general or universal property of matter, even if he at times took a step back from this claim and called it a “supposition.” Crucially, (...) sensibility is here playing the role of a ‘booster’: it enables materialism to provide a full and rich account of the phenomena of conscious, sentient life, contrary to what its opponents hold: for if matter can sense, and sensibility is not a merely mechanical process, then the loftiest cognitive plateaus are accessible to materialist analysis, or at least belong to one and the same world as the rest of matter. This was noted by the astute anti-materialist critic, the Abbé Lelarge de Lignac, who, in his 1751 Lettres à un Amériquain, criticized Buffon for “granting to the body [la machine, a common term for the body at the time] a quality which is essential to minds, namely sensibility.” This view, here attributed to Buffon and definitely held by Diderot, was comparatively rare. If we look for the sources of this concept, the most notable ones are physiological and medical treatises by prominent figures such as Robert Whytt, Albrecht von Haller and the Montpellier vitalist Théophile de Bordeu. We then have, or so I shall try to sketch out, an intellectual landscape in which new – or newly articulated – properties such as irritability and sensibility are presented either as an experimental property of muscle fibers, that can be understood mechanistically (Hallerian irritability, as studied recently by Hubert Steinke and Dominique Boury) or a property of matter itself (whether specifically living matter as in Bordeu and his fellow montpelliérains Ménuret and Fouquet, or matter in general, as in Diderot). I am by no means convinced that it is one and the same ‘sensibility’ that is at issue in debates between these figures (as when Bordeu attacks Haller’s distinction between irritability and sensibility and claims that ‘his own’ property of sensibility is both more correct and more fundamental in organic beings), but I am interested in mapping out a topography of the problem of sensibility as property of matter or as vital force in mid-eighteenth-century debates – not an exhaustive cartography of all possible positions or theories, but an attempt to understand the ‘triangulation’ of three views: a vitalist view in which sensibility is fundamental, matching up with a conception of the organism as the sum of parts conceived as little lives (Bordeu et al.); a mechanist, or ‘enhanced mechanist’ view in which one can work upwards, step by step from the basic property of irritability to the higher-level property of sensibility (Haller); and, more eclectic, a materialist view which seeks to combine the mechanistic, componential rigour and explanatory power of the Hallerian approach, with the monistic and metaphysically explosive potential of the vitalist approach (Diderot). It is my hope that examining Diderot in the context of this triangulated topography of sensibility as property sheds light on his famous proclamation regarding sensibility as a universal property of matter.

In this paper I interpret Newton’s speculative treatment of gravity as a relational, accidental property of matter that arises through what Newton calls “the shared action” of two bodies of matter. In doing so, I expand and extend on a hint by Howard Stein. However, in developing the details of my interpretation I end up disagreeing with Stein’s claim that for Newton a single body can generate a gravity/force field. I argue that when Newton drafted the first edition (...) of the Principia in the mid 1680s, he thought that (at least a part of) the cause of gravity is the disposition inherent in any individual body, but that the force of gravity is the actualization of that disposition; a necessary condition for the actualization of the disposition is the actual obtaining of a relation between two bodies having the disposition. The cause of gravity is not essential to matter because God could have created matter without that disposition. Nevertheless, at least a part of the cause of gravity inheres in individual bodies and were there one body in the universe it would inhere in that body. On the other hand, the force of gravity is neither essential to matter nor inherent in matter, because (to repeat) it is the actualization of a shared disposition. A lone part-less particle would, thus, not generate a gravity field. Seeing this allows us to helpfully distinguish among a) accepting gravity as causally real; b) the cause(s) (e.g. the qualities of matter) of the properties of gravity; c) making claims about the mechanism or medium by which gravity is transmitted. This will help clarify what Newton could have meant when he insisted that gravity is a real force. I present my argument in opposition to Andrew Janiak’s influential and fine 2007 paper. Along the way, I call attention to my disagreement with Janiak on a number of secondary issues (e.g. Janiak’s attribution to Newton of a distinction between ‘local’ and ‘distant’ action; Janiak’s reading of the “Letter to Bentley,” etc).

Let ‘semantic relevance’ be the thesis that the wide semantic properties of representational mental states (like beliefs and desires) are causally relevant to behavior. A popular way of arguing for semantic relevance runs as follows: start with a sufficient counterfactual condition for causal or explanatory relevance, and show that wide semantic properties meet it with respect to behavior (e.g., Loewer & Lepore (1987,1989), Rescorla (2014), Yablo (2003)).This paper discusses an in‐principle limitation of this strategy: even the most sophisticated counterfactual criteria (...) systematically misclassify irrelevant properties as relevant when they stand in certain kinds of modal co‐variation or ‘entanglement’ relations to genuinely relevant properties. This entanglement problem, I argue, is more general and more serious than proponents of the counterfactual strategy have recognized: it threatens recent interventionist arguments for semantic relevance, and is not easily solved by appeal to proportionality or naturalness. I end by suggesting that proponents of semantic relevance may need to shift their attention from patterns of counterfactuals to the lawful psychological generalizations that explain them. (shrink)

forthcoming in Philosophy and Phenomenological Research.

This paper argues that the epistemic gap in philosophy of mind stems from the fact that our awareness of our subjective experiences is categorically different from our knowledge of external phenomena. Our knowledge of external objects is always mediated through empirical observation or theoretical descriptions, and does not afford us knowledge of the intrinsic nature of the thing referred to, whereas our awareness of our experiences is immediate and affords us knowledge of the intrinsic nature of our experiences. Finally, it (...) is argued that the thing itself referred to as “neural correlate of consciousness” is constituted by consciousness. (shrink)

SummaryThe events and thoughts which brought Michael Faraday to the discovery of diamagnetism in the year 1845 are reviewed and commented. The contribution of Bancalari, namely the discovery of diamagnetism in flame and gases made at the University of Genoa in 1847, had a strong impact on the continuation of Faraday's brilliant researches on magnetism in matter. Diamagnetism was carefully studied by him and other authors, while paramagnetism was revealed in solid, liquid, and gaseous substances. A systematic study of (...) the magnetic properties of matter thus had its very beginning.The great number of skilful experiments carried out by Faraday from 1849 to 1851 led him to check in detail, in the case of magnetism, his concept of lines of force. In 1852, with the new phrase ‘physical lines of magnetic force’, Faraday was able to introduce and extensively discuss what may be called today a ‘field theory’ suitable for the description of magnetic action both inside and outside matter.Faraday's suspicious attitude toward the atomic theory prevented him proposing a microscopic explanation of the magnetic properties of matter. The thinking of Ampère and his followers was different; they developed models in order to understand magnetism in matter in terms of molecular currents. Bancalari, under the influence of Avogadro, was a convinced supporter of the atomic theory. Unfortunately, from the scanty documents, it is not possible to infer whether he had in mind any particular model for molecular magnetism. (shrink)

Pierre Louis Moreau de Maupertuis’ famous and influential Discours sur les différentes figures des astres, which represented the first public defense of attractionism in the Cartesian stronghold of the Paris Academy, sometimes suggests a metaphysically agnostic defense of gravity as simply a regularity. However, Maupertuis’ considered account in the essay, I argue, is much more subtle. I analyze Maupertuis’ position, showing how it is generated by an extended consideration of the possibility of attraction as an inherent property and fuelled by (...) an understanding of Lockean skepticism about knowledge of real essences that is more nuanced perhaps even than Locke’s own.

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

Since the seventeenth century, mind-body dualism has undergone an evolution, both in its metaphysics and its supporting arguments. In particular, debates in seventeenth- and eighteenth-century England prepared the way for the fall of substance dualism—the view that the human mind is an immaterial substance capable of independent existence—and the rise of a much less radical property dualism. The evolution from the faltering plausibility of substance dualism to the growing appeal of property dualism depended on at least two factors. On the (...) one hand, there was an increasing recognition of the causal and ontological interdependence of mind and body. Important here was a growing appreciation of the dependence of thought and perception on complex activities in the brain. On the other hand, there was a reconceptualization of the nature of matter; no longer inert and passive, matter came to be viewed as active in its own right. The old arguments lost much of their force, opening the door to a new sort of argument. Rather than appealing to the supposed immaterial nature of mental substance and volition, arguments for dualism began to appeal to the subjective nature of conscious experience—and its inexplicable emergence from the brain—as proof of the ontological distinctiveness of conscious properties. Consequently, the nineteenth and twentieth centuries saw the ascent of a more plausible, but still very problematic, property dualism, a position that to this day enjoys significant support.

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)

By what right do sovereign states prohibit migrants from entering their territories? It cannot be assumed that they do, certainly not as a matter of the way we define “sovereignty.” Can the sovereign right to exclude immigrants be derived from the sovereign’s status as owner of the territory it controls? This Article shows that the idea of the sovereign as owner is too problematic to be the basis of any argument for the right to exclude. It also argues against (...) the proposition that communities, considered as informal sovereigns, have a right to exclude based on their communal property in the land they inhabit. In both cases, an “ownership conception” is distinguished from a more attractive “responsibility conception” of sovereignty. The former remains unclear, while the latter leaves open the question of who the sovereign is responsible for. (shrink)

There is a common view, dating back at least to Hume, that property rights presuppose scarcity. This paper is a critical examination of that thesis. In addition to questioning the thesis, the paper highlights the need to divorce the debate over this thesis from the debate over Intellectual Property (IP) rights (the area where it is most frequently applied). I begin by laying out the thesis’ major line of defense. In brief, the argument is that (1) property rights are legitimate (...) only when necessary, (2) necessary only to avoid injury resulting from one party’s use or possession of a good over others’, and (3) that such injury is possible only where there is scarcity. While I accept (1) (at least for the sake of argument), I argue that each of three prominent theories of the justification of property rights cast doubt on (2) and (3). As it turns out, at the theoretical level, there are a number of different ways of dealing with this conflict. However, I argue, no matter which theoretical path one takes, it turns out that the practical implications of the relationship between property rights and scarcity have been woefully misconstrued. Finally, I recount an independent argument for the thesis under consideration and argue that, whether or not it is successful against IP, it does not extend as an argument against ownership of non-scarce goods in general. This serves to further highlight the need to distinguish arguments for the thesis under consideration from arguments against IP. (shrink)

How can a parcel of matter, or collection of particles, simultaneously compose three different objects, characterized by different modal properties? If the statue is gouged it still exists, but not exactly that piece of gold which originally occupied the statue’s borders, and the (mass of) gold within that piece can survive dispersal, while the piece cannot. The solution to this “problem of coinciding objects”, this paper argues, is that there is, in that space, only the statue. The properties which (...) the piece and the mass supposedly must have, to go on being, are not properties which anything can have necessarily or essentially. Not even having that origin can be essential. There is no object of which the statue is composed, though there are objects (viz., gold atoms) and a kind of stuff (viz., gold) of which it is composed.

Derek Parfit's Reasons and Persons (1984) mounted a striking defense of Act Consequentialism against a Rawls-inspired Kantian orthodoxy in moral philosophy. On What Matters (2011) is notable for its serious engagement with Kant's ethics and for its arguments in support of the “Triple Theory,” which allies Rule Consequentialism with Kantian and Scanlonian Contractualism against Act Consequentialism as a theory of moral right. This critical notice argues that what underlies this change is a view of the deontic concept of moral rightness (...) that ties it closely to blameworthiness and accountability in a way that effectively concedes a Rawlsian publicity condition. It is also argued that Parfit's arguments that Kantian and Scanlonian Contractualism entail Rule Consequentialism can be resisted. Two elements of Parfit's metaethics are critically discussed. First, concerning Parfit's arguments against subjectivist theories of practical reason, it is argued that a form of subjectivist theory exists that is not only consistent with Parfit's claim that all reasons for acting are object rather than state given, but that can support that claim. Second, it is argued that Parfit's arguments against identifying normative with natural statements and facts do not transfer seamlessly to identifying normative with natural properties. (shrink)

Neutron matter-wave optics provides the basis for new quantum experiments and a step towards applications of quantum phenomena. Most experiments have been performed with a perfect crystal neutron interferometer where widely separated coherent beams can be manipulated individually. Various geometric phases have been measured and their robustness against fluctuation effects has been proven, which may become a useful property for advanced quantum communication. Quantum contextuality for single particle systems shows that quantum correlations are to some extent more demanding than (...) classical ones. In this case entanglement between external and internal degrees of freedom offers new insights into basic laws of quantum physics. Non-contextuality hidden variable theories can be rejected by arguments based on the Kochen-Specker theorem. (shrink)

We present a new “reason-based” approach to the formal representation of moral theories, drawing on recent decision-theoretic work. We show that any moral theory within a very large class can be represented in terms of two parameters: a specification of which properties of the objects of moral choice matter in any given context, and a specification of how these properties matter. Reason-based representations provide a very general taxonomy of moral theories, as differences among theories can be attributed to (...) differences in their two key parameters. We can thus formalize several distinctions, such as between consequentialist and non-consequentialist theories, between universalist and relativist theories, between agent-neutral and agent-relative theories, between monistic and pluralistic theories, between atomistic and holistic theories, and between theories with a teleological structure and those without. Reason-based representations also shed light on an important but under-appreciated phenomenon: the “underdetermination of moral theory by deontic content”. (shrink)

David Lewis may be regarded as an antiessentialist. The reason is that he is said to believe that individuals do not have essential properties independent of the ways they are represented. According to him, indeed, the properties that are determined to be essential to individuals are a matter of which similarity relations among individuals are salient, and salience, in turn, is a contextual matter also determined to some extent by the ways individuals are represented. Todd Buras argues that (...) the acknowledgment of natural properties in counterpart theoretic ontology affects Lewis’s theory with regard to essentialism. Buras’s reasoning is appealing. He claims that, since natural properties determine the existence of similarity relations among individuals that are salient independent of context, Lewis can no longer be claimed to be an antiessentialist. The aim of this paper is to argue, against Buras, that if counterpart theory was antiessentialist before natural properties were taken into account, then it remains so afterwards. (shrink)

Professor Arda Denkel argues here that objects are nothing more than bundles of properties. From this point of view he tackles some central questions of ontology: how is an object distinct from others; how does it remain the same while it changes through time? A second contention is that properties are particular entities restricted to the objects they inhabit. The appearance that they exist generally, in a multitude of things, is due to the way we conceptualize them. Other problems dealt (...) with include how objects bear similarities by belonging to the same kinds, and how change in them is caused. Denkel defends a thoroughgoing particularism and offers purely qualitative accounts of individuation, identity, essences and matter. Throughout, the main alternative positions are surveyed, and the relevant historical background is traced. (shrink)

This paper defines relational properties and argues for their reducibility in a, broadly speaking, Armstrongian framework of state of affairs ontology and truthmaking. While Armstrong’s own characterisation and reduction of them arguably is the best one available in the literature of this framework, it suffers from two main problems. As will be shown, it neither defines relational properties very clearly (if at all), nor provides an adequate conception of their reduction. This paper attempts to remedy this situation in four steps. (...) First, it introduces relational properties and why they matter in metaphysics in general. Second, by briefly comparing and contrasting them with extrinsic properties, and by briefly mapping them onto a tripartite division of relations, the particular kinds of relevant relational properties are identified. Third, it classifies relational properties and thereby makes possible an apt definition of them. Finally, using the notion of truthmaking, it outlines a more satisfactory case for their reduction.

Varieties of chemical and phase equilibria are controlled by the minimum Gibbs energy principle, according to which the Gibbs energy for a system will have the minimum value at any given temperature and pressure. It is understood that the minimum is with respect to all nonequilibrium states at the same temperature and pressure. The abstract relation between Gibbs energy and the equilibrium constant is deduced from fundamental laws of thermodynamics. However, actual use of this relation calls for the Gibbs energy (...) as a function of concentrations of the chemicals. Since thermodynamics is formulated without any reference to materials, how does one get that relation? This article provides the answer, and in the process shows that application of theory to experiments requires several intermediate layers where theory and experiment commingle. (shrink)

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

Matter’s real essence is a ground for certain features of phenomena. Things in themselves are likewise a ground for certain features of phenomena. How do these claims relate? The former is a causal essentialism about physics, Stang argues; and the features so grounded are phenomenally nomically necessary. The latter involves a distinctive ontology of things in themselves, I argue; but the features so grounded are not noumenally nomically necessary. Stang’s version of Kant’s modal metaphysics is admirable, but does not (...) go far enough. Kant’s causal essentialism involves the essences of fundamental properties, as well as of matter. And things in themselves are grounds, because they are substances, the ‘substrate’ of phenomena. (shrink)

Aristotelian notions such as matter, form and substance should be used carefully; not only is the rich tradition in their background marked by variety of interpretation, even Aristotle's own use of these concepts is far from uniform. In his different works, matter, form and substance display contents that do not always agree. There is reason for believing that in the Metaphysics Zeta the notion of form embodies essence, and that accordingly something without essence does not qualify as substance. (...) This cannot be generalized or regarded as Aristotle's standard view, however, for in the Physics there are contexts in which the form is not conceived as essence. There, “the form or shape” is the arrangement of the substance's parts, or the object's shape, in addition to either all or some of its qualities. Outside the Metaphysics, substance, too, seems to be a less distinguished entity. In the Physics, and especially in the Categories, substance is anything capable of independent existence, any particular concrete thing that is a bearer of attributes. To the extent that our modern “object” corresponds to Aristotle's primary substance, it has a similar polysemy. While in some contexts it will mean an articulated object belonging to a specific kind, in others it will denote bodies without organized structure, that is, it will have as extension the particular bits and pieces that fill the world. A similar diversity applies to matter. When understood, for example, as a chunk out of which an artist casts her statue, matter is an object, a body, itself endowed with a boundary and a multitude of properties. But matter can be much simpler than that; it can be a plain homoeomere, a mere element, or as in prime matter, may lack every actual attribute. When in my “Matter and Objecthood” I criticized Henry Laycock's views propounded in “Some Questions of Ontology” I found comparable ambiguities transposed to contemporary discourse. In the paper just cited, Laycock examines the ontic status of matter, contrasting it with objects as particular concrete things; throughout his discussion no radical distinction is made between articulated objects and unorganized bodies. In my criticism I employed ‘object’ in the same inclusive sense. (shrink)

The problem of epistemological reflection has many aspects. Epistemology and logic are not the only disciplines in which it is studied. The life sciences, social sciences, and certain of the theoretical technological disciplines - all have a direct bearing upon it. In studying this complex problem it is desirable once again to seek a clarification of the fundamental features of the basic "unit" of reflection, employing the data of these sciences to this end. This is desirable not only with respect (...) to specialized studies of the reflection problem, but also because of the trend toward combining them, as, for example, in efforts to model mental functions in cybernetics.

In frameworks in which _topic-__theoretic_ considerations—_e.g._, tracking _subject-matter_ or _topic_—are given equal importance with _veridical_ considerations, assigning topics to formulae in a satisfactory way is of critical importance. While intuitions are more-or-less solid for _extensional_ formulae in a propositional language, arriving at a compelling account of the subject-matter of _intensional_ formulae, _i.e._, formulae including intensional operators, is more challenging. This paper continues previous work on modeling topics of intensional formulae in William Parry’s logic of analytic implication, adapting the general (...) techniques to the framework of _topic-sensitive intentional modals_ (TSIMs) championed by Francesco Berto and his collaborators. As illustrations, we introduce variations on Berto and Peter Hawke’s logic of knowability relative to information ( \(\pmb {\textsf{KRI}}\) ), including a refinement sensitive to topic-theoretic distinctions between knowledge and belief and a refinement capable of internalizing its own properties. Finally, subsystems of Aybüke Ozgun and Berto’s logic of plain hyperintensional belief ( \(\pmb {\textsf{PHB}}\) ) are introduced in which fine-grained distinctions in subject-matter are possible.

In the context of Aristotle's metaphysics and natural philosophy, 'prime matter' refers to that material cause which is both the proximate material cause of the four sublunary elements and the ultimate material cause of all perishable substances. On the traditional view, prime matter is pure potentiality, without any determinate nature of its own. Against this view, I argue that prime matter must be physical, extended, and movable matter if it is to fulfil its role as the (...) substratum persisting through the generation and corruption of these elements and the individuating subject in which their defining properties are found.

Properties and concepts are similar kinds of thing in so far as they are both typically understood to be whatever it is that predicates stand for. However, they are generally supposed to have different identity criteria: for example, heat is the same property as molecular kinetic energy, whereas the concept of heat is different from the concept of molecular kinetic energy. This paper examines whether this discrepancy is really defensible, and concludes that matters are more complex than is generally thought. (...) The distinction between canonical and non-canonical designators, as applied to such entities as propositions, properties and concepts, is examined, as are causal realist accounts of the semantics of such terms as ‘electricity’ and ‘mass’.

Morris Cohen’s classic essay, Property and Sovereignty, correctly discerned that political sovereignty and private property are alternative forms of government. Where it failed was in suggesting that the choice between these modes of governance is a matter of dialing one up and the other down. The relationship between political sovereignty and property is complex, and varies depending on the audience of property we have in view. With respect to some audiences — strangers and transactors — those who favor a (...) strong system of property will want to enlist a generous measure of assistance from the political sovereign. With respect to other audiences — neighbors and sharers — those who want a robust property system are more likely to want the powers of the political sovereign to be held in check. Cohen was thus right that the political order and private property are both forms of power over people. But the exact mix of these two regimes is anything but simple or unidimensional. (shrink)

In an interesting letter to Anna George, the daughter of Henry George, Bernard Shaw wrote: “Your father found me a literary dilettante and militant rationalist in religion, and a barren rascal at that. By turning my mind to economics he made a man of me”. I am not able to determine what making a man of Bernard Shaw would exactly consist of, but it is clear that the kind of moral and social problems with which Shaw was deeply concerned could (...) not be sensibly pursued without examining their economic aspects. For example, the claims of property rights, which some would defend and some would dispute, are not just matters of basic moral belief that could not possibly be influenced one way or the other by any empirical arguments. They call for sensitive moral analysis responsive to empirical realities, including economic ones. (shrink)
