In the recent literature on the nature of sound, there is an emerging consensus rejection of what might be thought of as the scientifically informed commonsense position: that sounds, whatever else they may be, must be entities that mediate between the source of the sound and the subject hearing it. This paper offers an argument for such "medial" theories of sound. This argument is intended to shift attention from the two considerations that have dominated the debate (...) thus far: the relevant scientific facts about audition and the spatial phenomenology of auditory experience.

Theorists have recently defended rival analyses of sound. The leading analyses reduce sound to sensations or mental representations, longitudinal compression waves, or sounding objects or events. Participants in the debate presuppose that because the features of the world targeted by these reductive strategies are distinct, at most one of the analyses is correct. In this article I argue that this presupposition is mistaken, endorsing a polysemy analysis of ‘sound’. Thus the ‘What is sound?’ debate is largely (...) merely verbal, or so I argue. All participants in this debate agree that there are the various reductions, they simply differ over which of them ‘is sound’. Yet there is no reason to think that, say, psychologists studying auditory sensations/representations, audio physicists studying sound waves, and anthropologists/ethnomusicologists studying sounding objects/events aren’t just studying different reductions of ‘sound’ despite the different explananda of their research. According to the polysemy theory of sound, we do not need to uniquely identify sound with one of these various explananda, outside of some context. (shrink)

This book provides an alternative (better) way to understand the future of acoustics, especially in the dialectic context of sound and silence-while learning from different approaches in the literature but without favoring any one of them (nor integrating them, since they are not necessarily compatible with each other). In other words, this book offers a new theory (that is, the multilateral theory of acoustics) to go beyond the existing approaches in the literature on acoustics in an original way.

Vision has dominated philosophical thinking about perceptual experience and the nature of its objects. Color has long been the focus of debates about the metaphysics of sensible qualities, and philosophers have struggled to articulate the conditions on the visual experience of mind-independent objects. With few notable exceptions, "visuocentrism" has shaped our understanding of the nature and functions of perception, and of our conception of its objects. The predominant line of thought from the early modern era to the present is that, (...) in the philosophically interesting respects, as things are with vision, so they are with hearing, touch, olfaction, and the rest. A closely related line of thought has been particularly strong in the case of the secondary qualities. (shrink)

I defend and develop a traditional view in the metaphysics of sound, The Wave Theory of Sound. According The Wave Theory, as developed herein, sounds are not patterned disturbances so much as their propagation. And the propagation of a patterned disturbance is not a form of travel, but a dynamic in-formation, the wave-form successively inhering in diferently located parts of the dense and elastic medium. This conception, along with the assumption that we hear not only sounds but their (...) sources, has the resources to address many of the most recent criticisms of this traditional view. (shrink)

Sound and Grammar: A Neo-Sapirian Theory of Language by Susan F. Schmerling offers an original overall linguistic theory based on the work of the early American linguist Edward Sapir, supplemented with ideas from the philosopher-logicians Kazimierz Ajdukiewicz and Richard Montague and the linguist Elisabeth Selkirk. The theory yields an improved understanding of interactions among different aspects of linguistic structure, resolving notorious issues directly inherited by current theory from (post- ) Bloomfieldian linguistics. In the theory presented here, syntax is a (...) filter on a phonological algebra, not a linguistic level; linguistic expressions are phonological structures, and syntax is semantically relevant relations among phonological structures. The book shows how Neo-Sapirian grammar sheds new light on syntax-phonology interactions in English, German, French, and Spanish. (shrink)

This essay offers an introduction to Hegel's philosophy of sound as elaborated in the 1830 Encyclopaedia of the Philosophical Sciences in Basic Outline. The first section begins with essential context for interpreting the a priori status of nature and sound in Hegel's Philosophy of Nature. Next, I develop a general account of the Aristotelian character of Hegel's ‘Physics’, and a commentary on the categories of specific gravity and cohesion leading up to sound (and heat) in the ‘Physics (...) of Particular Individuality’. The second section provides an exegetical portrait of Hegel's metaphysics of sound. I first reconstruct Hegel's ontology of sound from the subsection on ‘Sound’ (Der Klang), and then outline his theory of auditory perception. The third section compares Hegel's philosophy of sound to leading views in contemporary philosophy of sound. I argue that Hegel offers a hylomorphic version of a located event theory of sound, which I suggest is more phenomenologically adequate than the modern acoustic view, and more metaphysically consistent than other distal event theories of sound.

Rudolph Koenig's workshop was a busy meeting place for instruments, ideas, experiments, demonstrations, craft traditions, and business. Starting around 1860, it was also the place in Paris where people discovered the new science of sound emerging from the studies of Hermann von Helmholtz in Germany. Koenig built Helmholtz's ideas into apparatus, created new instruments, and spread them throughout the scientific and musical world. Through his own research, he also became Helmholtz's strongest critic. This paper looks at the activities of (...) this unique space and, in particular, how it contributed to the protracted disputes over an elusive acoustical phenomenon called the combination tone.

Infectious logics are systems that have a truth-value that is assigned to a compound formula whenever it is assigned to one of its components. This paper studies four-valued infectious logics as the basis of transparent theories of truth. This take is motivated as a way to treat different pathological sentences differently, namely, by allowing some of them to be truth-value gluts and some others to be truth-value gaps and as a way to treat the semantic pathology suffered by at (...) least some of these sentences as infectious. This leads us to consider four distinct four-valued logics: one where truth-value gaps are infectious, but gluts are not; one where truth-value gluts are infectious, but gaps are not; and two logics where both gluts and gaps are infectious, in some sense. Additionally, we focus on the proof theory of these systems, by offering a discussion of two related topics. On the one hand, we prove some limitations regarding the possibility of providing standard Gentzen sequent calculi for these systems, by dualizing and extending some recent results for infectious logics. On the other hand, we provide sound and complete four-sided sequent calculi, arguing that the most important technical and philosophical features taken into account to usually prefer standard calculi are, indeed, enjoyed by the four-sided systems.

This dissertation aims to revive wave theory in the philosophy of sound. Wave theory identifies sounds with compression waves. Despite its wide acceptance in the scientific community as the default position, many philosophers have rejected wave theory and opted for different versions of distal theory instead. According to this current majority view, a sound has its stationary location at its source. I argue against this and other alternative philosophical theories of sound and develop wave theory into (...) a more defensible form. Philosophers of sound tend to emphasise how sounds are experienced to be in their arguments. Most often, it is assumed that that which appears to be a distally located bearer of auditory properties in an auditory experience is a sound. Chapter 1 argues that if this distal entity is the sound source instead, many of the existing theories of sound will be severely affected. Chapter 2 discusses auditory perception and criticises the common assumption that we hear non-sound entities in virtue of hearing sounds. I show that this assumption begs the question against certain theories of sound and that the contrary view that sound sources can be directly heard is more plausible. If sound sources can be directly heard, then features commonly attributed to sounds based on auditory experiences might rather be features of sound sources. I examine eight of such features in Chapter 3. Only four of them survive. Chapters 4 and 5 review the existing theories of sound. After a taxonomy of existing theories of sound, each theory is criticised one-by-one. Some of them are problematic precisely because they rely on the implausible assumption that that which appears to be distally located in an auditory experience is a sound rather than a sound source. Lastly, Chapter 6 focuses on wave theory. It begins with two positive arguments for wave theory in general, followed by my replies to two common objections in the literature. I then move on to develop my version of wave theory. There are two core aspects of my view. The first one is a metaphysics of compression waves; the second is an account of what it is to hear compression waves. After comparing my view with a similar theory, I demonstrate the explanatory power of my view in two steps. First, the eight commonly accepted features of sounds examined in Chapter 3 are revisited. It turns out that my view can accommodate all of them. Second, explanations for four special sound-related phenomena are offered at the end of the chapter. I conclude in the last chapter with the suggestion that, as a philosopher, the best way to defend wave theory is to offer a better understanding of auditory perception which explains how compression waves are experienced.

In "Playing with Sound," Karen Collins examines video game sound from the player's perspective.

Kant is well known as the philosopher who spent his life hunting for a prioris, philosophically identifiable characteristics of the make-up of human beings. These characteristics are species-universal, and are necessary presuppositions of the possibility of the success of various kinds of cognitive and cultural strategies. Kant bagged some big game. Space, time and the categories are a priori conditions of the possibility of human cognition. God, freedom and immortality are a priori conditions of the possibility of morality. The sensus (...) communis is the a priori condition of the possibility of the universalization of judgments of taste. The hard-won trophies are presuppositions of possibilities. Once they were thought to be properties of a universe well ordered by a substantive god. No longer. Now we must look upon them as entrenched contributions of what it is to be human, as preconditions of human potentialities. (shrink)

Many liberal political philosophers hold that the state should not impose or even promote any particular conception of the good life or human flourishing. It should not, for instance, enact laws and policies designed to elevate citizens' tastes, to refine their sensibilities or to perfect their characters. Instead, the state should restrict itself to maintaining a fair framework of rights and opportunities within which all citizens can pursue their own beliefs about what constitutes a good life. Against this backdrop, Collis (...) Tahzib develops a version of perfectionist political philosophy. Whereas previous perfectionists have argued that the promotion of flourishing ways of life is permissible or legitimate, Tahzib casts perfectionism as a doctrine of justice. On this view, the implementation of laws and policies designed to promote sound ideals of the good life--ideals such as moral, intellectual and artistic excellence--is not merely a legitimate complement to justice but an essential constituent of justice. Over the years, perfectionism has faced various objections: that it is premised on values and judgements that are controversial within modern pluralistic societies; that it is unduly restrictive of freedom or autonomy; that it treats citizens as if they are children, unable to run their own lives; that it expresses the meddlesome mentality of a village busybody; that it mistakenly assumes that there are objective truths about human flourishing; and that it risks the abuse of power by incompetent, overzealous or corrupt state officials. These ideas represent some of the deepest, most vibrant and most powerful strains in liberal thought. In defending perfectionism against these charges, the arguments in A Perfectionist Theory of Justice make a novel and important contribution to longstanding debates about the philosophical foundations of liberalism.

Summary Music has been primarily conceived as a temporal art. However, over the last two centuries or so, researchers across different disciplines including musicology, psychology, and philosophy, have been intrigued by the spatial nature of music and sounds, using spatial concepts to define music. This paper aims to demonstrate that an understanding of music perception from a temporal perspective inherently implies a certain spatial dimension. To do this, first, I briefly examine some key arguments that lead to conceiving sound (...) perception in temporal terms. At the same time, I highlight some of the limitations of a purely temporal account of sound perception which necessitate the incorporation of spatial considerations into the conceptualization of sound perception. Consequently, I move on to consider prominent spatial accounts of musical sounds that have been elaborated by psychologists, musicologists, and music composers. In conclusion, I discuss some of the challenges arising from the analogy between music and space, whether conceived in perceptual or cognitive terms. (shrink)

This monograph is a detailed study, and systematic defence, of the Growing Block Theory of time (GBT), first conceived by C.D. Broad. The book offers a coherent, logically perspicuous and ideologically lean formulation of GBT, defends it against the most notorious objections to be found in the extant philosophical literature, and shows how it can be derived from a more general theory, consistent with relativistic spacetime, on the pre-relativistic assumption of an absolute and total temporal order. -/- The authors devise (...) axiomatizations of GBT and its competitors which, against the backdrop of a shared quantified tense logic, significantly improves the prospects of their comparative assessment. Importantly, neither of these axiomatizations involves commitment to properties of presentness, pastness or futurity. The authors proceed to address, and defuse, a number of objections that have been marshaled against GBT, including the so-called epistemic objection according to which the theory invites skepticism about our temporal location. The challenge posed by relativistic physics is met head-on, by replacing claims about temporal variation by claims about variation across spacetime. -/- The book aims to achieve the greatest possible rigor. The background logic is set out in detail, as are the principles governing the notions of precedence and temporal location. The authors likewise devise a novel spacetime logic suited for the articulation, and comparative assessment, of relativistic theories of time. The book comes with three technical appendices which include soundness and completeness proofs for the systems corresponding to GBT and its competitors, in both their pre-relativistic and relativistic forms. -/- The book is primarily directed at researchers and graduate students working on the philosophy of time or temporal logic, but is of interest to metaphysicians and philosophical logicians more generally.

Ernst Mach is the only person whom Einstein included on both the list of physicists he considered his true precursors, and the list of the philosophers who had most affected him. Einstein scholars have been less generous in their estimation of Mach's contributions to Einstein's work, and even amongst the more generous of them, Mach's great achievements in physics are seldom mentioned in this context. This is odd, considering Mach was nominated for the Nobel Prize in Physics three times. In (...) this paper, I examine some of Mach's work in physics that bears conceptually on Einstein's 1905 paper on Special Relativity ("On The Electrodynamics of Moving Bodies"). Mach was the first to give the correct explanation of the Doppler Effect, and he presented it in a way that Einstein echoes in his 1905 paper: laying out two apparently contradictory principles and showing how both can be retained. It is also notable that Mach's explanation was explicit about not relying on the existence of a medium of transmission for the propagation of light waves. In his work on supersonic shock waves, Mach invokes the constancy of the velocity of sound (i.e., its independence of the motion of the sound source) , just as he had invoked the constancy of the velocity of light in his work on the Doppler Effect for Light. I examine the analogies between light and sound that were drawn upon by Einstein and Mach, as well as one analogy that Einstein could have, but did not make: Cherenkov radiation, or "singing electrons", i.e., cases in which the sound of light in the medium of transmission is exceeded, which results in an optical analogue of supersonic shock waves.

This paper argues that Wittgenstein opposed theories of meaning, and did so for good reasons. Theories of meaning, in the sense discussed here, are attempts to explain what makes it the case that certain sounds, shapes, or movements are meaningful linguistic expressions. It is widely believed that Wittgenstein made fundamental contributions to this explanatory project. I argue, by contrast, that in both his early and later works, Wittgenstein endorsed a disjunctivist conception of language which rejects the assumption underlying (...) the question that such theories seek to answer—namely, the assumption that the notion of a meaningful linguistic expression admits of non-circular analysis. Moreover, I give two arguments in favor of the view I ascribe to Wittgenstein: one based on later Wittgenstein's discussion of meaning skepticism and one based on considerations concerning the identity of linguistic expressions.

1. IMPORTANCE OF THE SUBJECT In 1900, in A Critical Exposition of the Philosophy of Leihniz, Russell made the following assertion: "That all sound philosophy should begin with an analysis of propositions is a truth too evident, perhaps, to demand a proof". 1 Forty years later, the interest aroused by this notion had not decreased. C. J. Ducasse wrote in the Journal of Philosophy: "There is perhaps no question more basic for the theory of knowledge than that of the (...) nature of 2 propositions and their relations to judgments, sentences, facts and inferences". Today, the great number of publications on the subject is proof that it is still of interest. One of the problems raised by propositions, the problem of deter mining whether propositions, statements or sentences are the primary bearers of truth and falsity, is even in the eyes of Bar-Hillel, "one of the major items that the future philosophy oflanguage will have to discuss". 3 gave a correct summary of the situation when he wrote in his Ph. Devaux Russell : Since Peano and Schroder who, in fact, adhered more faithfully to Boole's logic of classes, the logical and epistemological status of the proposition together with its analysis have not ceased to be the object of productive philosophical controversies. And especially so since the establishment of contemporary symbolic logic, the foundations 4 of which have been laid out by Russell and Whitehead. * 2. (shrink)

Excerpt from A Study in the Theory of Value The thesis which I wish to defend in the present essay is a very common one, believed, I think, by most people, but usually only approximately and only half-heartedly, and expressed vaguely if expressed at all. Some such belief is in fact present whenever we reflect upon acts that stir our interest; but the belief baldly expressed in propositions sounds fanciful or weak or sentimental, and we avoid pronouncing it clearly in (...) much the same way as that in which we hurry over an expression in an unfamiliar language - partly from modesty, but. Mostly from fear of appearing ridiculous and from inner conviction Of ignorance. Our belief, in other words, not Only seems to us sentimental and weak when we approach the formulation of it in a creed, but it actually is sentimental and weak when thus formulated, and this for the reason that we have not taken the trouble to make the formulation accurate or definite. On the one hand we are afraid of seeming. Sentimental; on the other hand we do not know what our belief really is, nor what definite formula embodying it will stand the test of logical criticism.

Predicates such as tall or to know Latin, which intuitively denote permanent properties, are called individual-level predicates. Many peculiar properties of this class of predicates have been noted in the literature. One such property is that we cannot say #John is sometimes tall. Here is a way to account for this property: this sentence sounds odd because it triggers the scalar implicature that the alternative John is always tall is false, which cannot be, given that, if John is sometimes tall, (...) then he always is. This intuition faces two challenges. First: this scalar implicature has a weird nature, since it must be surprisingly robust (otherwise, it could be cancelled and the sentence rescued) and furthermore blind to the common knowledge that tallness is a permanent property (since this piece of common knowledge makes the two alternatives equivalent). Second: it is not clear how this intuition could be extended to other, more complicated properties of individual-level predicates. The goal of this paper is to defend the idea of an implicature-based theory of individual-level predicates by facing these two challenges. In the first part of the paper, I try to make sense of the weird nature of these special mismatching implicatures within the recent grammatical framework for scalar implicatures of Chierchia (Structures and beyond, 2004) and Fox (2007). In the second part of the paper, I show how this implicature-based line of reasoning can be extended to more complicated properties of individual-level predicates, such as restrictions on the interpretation of their bare plural subjects, noted in Carlson (Reference to kinds in English. Doctoral dissertation, University of Massachusetts at Amherst, 1977), Milsark (Linguistic Analysis 3.1: 1–29, 1977), and Fox (Natural Language Semantics 3: 283–341, 1995); restrictions on German word order, noted in Diesing (Indefinites, 1992); and restrictions on Q-adverbs, noted in Kratzer (The Generic Book, ed.

permits a sound and rigorously definable notion of ‘originating cause’ or causa causans—a type of transition event—of an outcome event. Mackie has famously suggested that causes form a family of ‘inus’ conditions, where an inus condition is ‘an insufficient but non-redundant part of an unnecessary but sufficient condition’. In this essay the needed concepts of BST theory are developed in detail, and it is then proved that the causae causantes of a given outcome event have exactly the structure of (...) a set of Mackie inus conditions. The proof requires the assumption that there is no EPR-like ‘funny business’. This seems enough to constitute a theory of ‘causation’ in at least one of its many senses.

Implicit in C. I. Lewis's conceptual pragmatism is an account of how our ideas undergo a process of social development. Lewis's account of that process resolves a problem with Josiah Royce's theory of ideas. Royce holds that there are both sensuous and symbolic ideas. It is, however, possible for someone to have only a sensuous idea of how middle C sounds and for another person to have only the symbolic idea that middle C is 261.63 Hz. In what sense, if (...) at all, can these two persons have the same idea, namely, the idea of middle C? On Lewis's account, while ideas in individual minds are typically constituted of both sensory correlates and pure concepts, ideas are also social products that individuals inherit through education and language acquisition. For two people to have the same idea is for them both to be heirs to the social development of the idea. (shrink)

A familiar feature of our moral responsibility practices are pleas: considerations, such as “That was an accident”, or “I didn’t know what else to do”, that attempt to get agents accused of wrongdoing off the hook. But why do these pleas have the normative force they do in fact have? Why does physical constraint excuse one from responsibility, while forgetfulness or laziness does not? I begin by laying out R. Jay Wallace’s (Responsibility and the moral sentiments, 1994 ) theory of (...) the normative force of excuses and exemptions. For each category of plea, Wallace offers a single governing moral principle that explains their normative force. The principle he identifies as governing excuses is the Principle of No Blameworthiness without Fault: an agent is blameworthy only if he has done something wrong. The principle he identifies as governing exemptions is the Principle of Reasonableness: an agent is morally accountable only if he is normatively competent. I argue that Wallace’s theory of exemptions is sound, but that his account of the normative force of excuses is problematic, in that it fails to explain the full range of excuses we offer in our practices, especially the excuses of addiction and extreme stress. I then develop a novel account of the normative force of excuses, which employs what I call the “Principle of Reasonable Opportunity,” that can explain the full range of excuses we offer and that is deeply unified with Wallace’s theory of the normative force of exemptions. An important implication of the theory I develop is that moral responsibility requires free will. (shrink)

... ISBN0199215928 ... -/- Abstract: Vision dominates philosophical thinking about perception, and theorizing about experience in cognitive science traditionally has focused on a visual model. This book presents a systematic treatment of sounds and auditory experience. It demonstrates how thinking about audition and appreciating the relationships among multiple sense modalities enriches our understanding of perception. It articulates the central questions that comprise the philosophy of sound, and proposes a novel theory of sounds and their perception. Against the widely accepted (...) philosophical view that sounds are among the secondary or sensible qualities, and against the scientific view that sounds are waves that propagate through a medium such as air or water, the book argues that sounds are events in which objects or interacting bodies disturb a surrounding medium. This does not imply that sounds propagate through a medium, such as air or water. Rather, sounds are events that take place in one's environment at or near their sources. This account captures the way in which sounds essentially are creatures of time and situates sounds in the world. Sounds are not ethereal, mysterious entities. It also provides a powerful account of echoes, interference, reverberation, Doppler effects, and perceptual constancies that surpasses the explanatory richness of alternative theories. Investigating sounds and audition demonstrates that considering other sense modalities teaches what we could not otherwise learn from thinking exclusively about the visual. This book concludes by arguing that a surprising class of cross-modal perceptual illusions demonstrates that the perceptual modalities cannot be completely understood in isolation, and that a visuocentric model for theorizing about perception — according to which perceptual modalities are discrete modes of experience and autonomous domains of philosophical and scientific inquiry — ought to be abandoned. -/- .

This article discusses “auditory” arguments: arguments in which non-verbal sounds play a central role. It provides examples and explores the use of sounds in argument and argumentation. It argues that auditory arguments are not reducible to verbal arguments but have a similar structure and can be evaluated by extending standard informal logic accounts of good argument. I conclude that an understanding of auditory elements of argument can usefully expand the scope of informal logic and argumentation theory.

The logical formalism of abductive reasoning is still an open discussion and various theories have been presented about it. Abduction is a type of non-monotonic and defeasible reasonings, and the logic containing such a reasoning is one of the types of non-nonmonotonic and defeasible logics, such as inductive logic. Abduction is a kind of natural reasoning and it is a solution to the problems having this form "the phenomenon of φ cannot be explained by the theory of Θ" and (...) we need to search for (or to adduce) an explanation for φ. Taking α as the explanation and <Θ,φ> as the abductive problem, Θ∪{α}⊨φ is the logical format of a strong abductive reasoning. In this article, the proof theory for first-order abductive calculus is proposed based on Gentzen-type first-order proof theory. Considering its dual, i.e., the semantic tableaux, and without the need to translate the formulas, this calculation is sound and complete. After examining the structural rules of this calculus, some metalogical considerations and open problems such as consistency, completeness and undecidability of this account have been addressed.

We investigate axiomatizations of Kripke's theory of truth based on the Strong Kleene evaluation scheme for treating sentences lacking a truth value. Feferman's axiomatization KF formulated in classical logic is an indirect approach, because it is not sound with respect to Kripke's semantics in the straightforward sense: only the sentences that can be proved to be true in KF are valid in Kripke's partial models. Reinhardt proposed to focus just on the sentences that can be proved to be true (...) in KF and conjectured that the detour through classical logic in KF is dispensable. We refute Reinhardt's Conjecture, and provide a direct axiomatization PKF of Kripke's theory in partial logic. We argue that any natural axiomatization of Kripke's theory in Strong Kleene logic has the same proof-theoretic strength as PKF, namely the strength of the system RA< ωω ramified analysis or a system of Tarskian ramified truth up to ωω. Thus any such axiomatization is much weaker than Feferman's axiomatization KF in classical logic, which is equivalent to the system RA<ε₀ of ramified analysis up to ε₀. (shrink)

The paper considers Plato’s theory of language through the prism of the Timaeus’ metaphysics. It is argued that the apparent contradictions of Plato’s philosophy of language are the consequence of the two-fold nature of language, and that the metaphysical scheme proposed by Plato in the Timaeus can shed a light on his coherent theory of language. The linguo-metaphysical isomorphism of the Timaeus presupposes that (1) words and material elements have their own meaning and nature respectively; (2) they can be reduced (...) to an infinite variety of amorphic sounds and receptacle; (3) the participation in truth is possible only at the level of narrative and universe. According to this scheme the universe (κόσμος), as well as any speech (λόγος), can be explained by the reduction to its constituent elements, but it will be only necessary explanation. Whereas for Plato, the true understanding of cosmos and logos is possible only on the level of the coherent unity of the whole, which represents the ideal paradigm in the best possible way. (shrink)

Against the medical and social models of disability are two newer proposals. Elizabeth Barnes’ Minority Body proposes that it is the bodies which are advocated for and included in the disability rights movement which are rightfully called “disabled.” Savulescu and Kahane’s Welfarist approach proposes that disability is intrinsically tied to the effects of bodily states on welfare. They put the need for a consistent and relatively simple normative theory above accounting for standard case judgements about who is and is not (...) disabled or looking at all to membership of the disabled community. I argue that Barnes’ theory offers the best response to issues with the dominant models of disability. Further, I argue that the Welfarist theory operates in a space removed from the wishes and lived experiences of disabled people – separating ‘disability’ from activism entirely – to its detriment. Doing so compromises its explanatory power, over-generalizes the concept and prevents the insertion of meaningful boundaries. Barnes’ ‘solidarity thesis’ soundly conceptualizes disability whilst making room for activist voices. The centering of activist projects makes it stronger. (shrink)

The aim of this paper is to offer a concise and faithful account of Rawls’ theory of international justice, in an effort, first, to elucidate the structure of the argument that is advanced in that theory and, second, to present a critical assessment of it. The critical assessment section attempts, on the one side, to cope with crucial methodological issues, which have a more general bearing upon Rawls’ overall political philosophical position, including the constructivist perspective of theory making and the (...) division between a political conception and a comprehensive doctrine; on the other side, to weigh up a set of substantive claims made in the Rawlsian theory of international justice, including the recognition of peoples as the fundamental subjects of international law, the toleration of the so-called decent peoples and the considerably thin construal of human rights encompassed in The Law of Peoples. The paper attempts to provide a series of reasons that could be well-suited to explicate its author’s doubts about the soundness of the Rawlsian theoretical perspective with regard to both its formal methodological features and its more content-oriented convictions.

Some 20 years ago Todd and colleagues proposed that rhythm perception is mediated by the conjunction of a sensory representation of the auditory input and a motor representation of the body (Todd, 1994a, 1995 ), and that a sense of motion from sound is mediated by the vestibular system (Todd, 1992a, 1993b ). These ideas were developed into a sensory-motor theory of rhythm and beat induction (Todd et al., 1999 ). A neurological substrate was proposed which might form the (...) biological basis of the theory (Todd et al., 2002 ). The theory was implemented as a computational model and a number of experiments conducted to test it. In the following time there have been several key developments. One is the demonstration that the vestibular system is primal to rhythm perception, and in related work several experiments have provided further evidence that rhythm perception is body dependent. Another is independent advances in imaging, which have revealed the brain areas associated with both vestibular processing and rhythm perception. A third is the finding that vestibular receptors contribute to auditory evoked potentials (Todd et al., 2014a, b ). These behavioral and neurobiological developments demand a theoretical overview which could provide a new synthesis over the domain of rhythm perception. In this paper we suggest four propositions as the basis for such a synthesis. (1) Rhythm perception is a form of vestibular perception; (2) Rhythm perception evokes both external and internal guidance of somatotopic representations; (3) A link from the limbic system to the internal guidance pathway mediates the “dance habit”; (4) The vestibular reward mechanism is innate. The new synthesis provides an explanation for a number of phenomena not often considered by rhythm researchers. We discuss these along with possible computational implementations and alternative models and propose a number of new directions for future research. (shrink)

The recent extension of quantum theory to sound waves in solids is briefly outlined and then discussed from a specific philosophic perspective.

I identify two components in the perception of musical pitches, which make pitch perception more like colour perception than it is usually taken to be. To back up this implausible claim I describe a programme whereby individuals can learn to identify the components in musical tones. I also claim that following this programme can affect one's pitch-recognition capacities.

This book gives an account of a full spectrum of property rights and their relationship to individual liberty. It shows that a purely deontological approach to justice can deal with the most complex questions regarding the property system. Moreover, the author considers the economic, ecological, and technological complexities of our real-world property systems. The result is a more conceptually sound account of natural rights and the property system they demand. If we think that liberty should be at the centre (...) of justice, what does that mean for the property system? Economists and lawyers widely agree that a property system must be composed of many different types of property: the kind of private ownership one has over one's person and immediate possessions, as well as the kinds of common ownership we each have in our local streets, as well as many more. However, theories of property and justice have not given anything approaching an adequate account of the relationship between liberty and any other form of property other than private ownership. It is often thought that a basic commitment to liberty cannot really tell us how to arrange the major complexities of the property system, which diverge from simple private ownership. Property and Justice demonstrates how philosophical rigour coupled with interdisciplinary engagement enables us to think clearly about how to deal with real-world problems. It will be of interest to political philosophers, political theorists, and legal theorists working on property rights and justice. (shrink)

The recent extension of quantum theory to sound waves in solids is briefly outlined and then discussed from a specific philosophic (Kantian) perspective.

Other-perspective taking, distancing, time discounting as well as risk and loss aversion highly affect decision-making. Even though they influence each other, so far these cognitive processes have been unrelated or only partly related to each other in neuroscience. This article proposes a philosophical interpretation of these cognitive processes that is elaborated in the updated theory of Adam Smith’s prudence. The UTSP is inspired by Smith’s account of prudence and is in line with the neuroscientific and behavioral studies on OPT, distancing, (...) time discounting as well as risk and loss aversion. The UTSP represents a framework aiming to interpret and connect these cognitive processes and providing a consistent and empirically sound account of a “Smithianly” prudent style of decision-making. The two pillars of the UTSP are the shift of perspective in space and time and loss aversion. On the basis of this theory, a normative updated theory of Smithian prudence is outlined. The latter is useful for moral philosophy for two reasons: firstly, according to preliminary evidence, it is effective in guiding the agent in decisional contexts in which her well-being is at stake and she can affect other people with her actions. Secondly, since the NUTSP is based on neuroscientific findings on decision-making, it has a sound empirical basis that prevents a source of alienation for the agent. (shrink)

This ambitious book presents a new interpretation of Chinese thought guided both by a philosopher's sense of mystery and by a sound philosophical theory of meaning. That dual goal, Hansen argues, requires a unified translation theory. It must provide a single coherent account of the issues that motivated both the recently untangled Chinese linguistic analysis and the familiar moral-political disputes. Hansen's unified approach uncovers a philosophical sophistication in Daoism that traditional accounts have overlooked. The Daoist theory treats the imperious (...) intuitionism that alienates critical thinkers as a feature of Confucianism alone. Freed from the view that Confucianism is the core of Chinese thought and from myopic Confucian interpretations, Chinese thinkers emerge as unmistakably philosophical. (shrink)

Sound has given rise to many rich theoretical reflections, but when compared to the study of images, the study of sound continues to be marginalized. How is the “sense” of sound constituted and elaborated linguistically, textually, technologically, phenomenologically, and geologically, as well as acoustically? How is sound grasped as an object? Considering sound both within and beyond the scope of the human senses, contributors from literature, film, music, philosophy, anthropology, media and communication, and science and (...) technology studies address topics that range from Descartes’s resonant subject to the gendering of hearing physiology in the nineteenth century, Cold War politics and the opera _Nixon in China_, sounds from the Mediterranean, the poetics of signal processing, and the acousmatic voice in the age of MP3s. In the interpretive challenges posed by voice, noise, antinoise, whispering, near inaudibility, and silence and in the frequent noncoincidence of emission and reception, sound confronts us with what might be called its inhuman qualities—its irreducibility to meaning, to communication, to information, and even to recognition and identification. _Rey Chow_ is Anne Firor Scott Professor of Literature at Duke University.

This paper argues for a version of metalinguistic descriptivism, the Mill-Frege view, comparing it to a currently popular alternative, predicativism. The Mill-Frege view combines tenets of Fregean views with features of the theory of direct reference. According to it, proper names have metalinguistic senses, known by competent speakers on the basis of their competence, which figure in ancillary presuppositions. In support of the view the paper argues that the name-bearing relation—which predicativists cite to account for the properties that they take (...) names to express—depends on acts of naming with a semantic significance. Acts of naming create particular words specifically designed for referential use, which they perform whether or not the language has other words articulated with the same sound or orthography. Like other forms of metalinguistic descriptivism, the Mill-Frege view affords responses to Kripke’s semantic and epistemic arguments against descriptivism. The view is prima facie more complex than predicativism; but the additional complexity is independently attested in natural languages and well-motivated. Finally, the Mill-Frege proposal deals well with Kripke’s modal argument, and accounts for modal intuitions about names, both issues that pose serious trouble to predicativism. (shrink)
