Mark Eli Kalderon presents an original study of perception, taking as its starting point a puzzle in Empedocles' theory of vision: if perception is a mode of material assimilation, how can we perceive colors at a distance? Kalderon argues that the theory of perception offered by Aristotle in answer to the puzzle is both attractive and defensible.

Geach's problem, the problem of accounting for the fact that judgements expressed using moral terms function logically like other judgements, stands in the way of most noncognitive analyses of moral judgements. The non-cognitivist must offer a plausible interpretation of such terms when they appear in conditionals that also explains their logical interaction with straightforward moral assertions. Blackburn and Gibbard have offered a series of accounts each of which interprets such conditionals as expressing higher order commitments. Each then invokes norms for (...) the coherent acceptance of attitudes to explain why we hold certain combinations inconsistent. Against these accounts the paper presses two related objections: (1) The norms needed to do the explanatory work cannot be strong enough to do that work without also ruling clearly consistent attitudes inconsistent. And (2), the norms of rational attitude acceptance do not neatly track the distinction between consistent and inconsistent attitudes. (shrink)

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will offer an account based on our knowledge of the natures, or essencess, of things. I will argue that essences need not be viewed as metaphysically bizarre entities; that we can conceptualise and refer to (...) essences; and that we can gain knowledge of them. We can know about which properties are, and which properties are not, essential to a given entity. This knowledge of essence offers a route to knowledge of the ways those entities must be or could be. (shrink)

This paper offers a new way to make sense of disagreement expansion from a polylogical perspective by incorporating various places in addition to players and positions into the analysis. The concepts build on prior implicit ideas about disagreement space by suggesting how to more fully account for argumentative context, and its construction, in large-scale complex controversies. As a basis for our polylogical analysis, we use a New York Times news story reporting on an oil train explosion—a significant point in the (...) broader controversy over producing oil and gas via hydraulic fracturing.

Bundle theories identify material objects with bundles of properties. On the traditional approach, these are the properties possessed by that material object. That view faces a deep problem: it seems to say that all of an object’s properties are essential to it.Essential bundle theoryattempts to overcome this objection, by taking the bundle as a specification of the object’s essential properties only. In this paper, I show that essential bundle theory faces a variant of the objection. To avoid the problem, the (...) theory must accept the contingency of identity. I show how this can be achieved in a coherent and well-motivated way, a way that isn’t available to traditional bundle theories. (shrink)

Generic generalisations like ‘Opioids are highly addictive’ are very useful in scientific communication, but they can often be interpreted in many different ways. Although this is not a problem when all interpretations provide the same answer to the question under discussion, a problem arises when a generic generalisation is used to answer a question other than that originally intended. In such cases, some interpretations of the generalisation might answer the question in a way that the original speaker would not endorse. (...) Rather than excising generic generalisations from scientific communication, I recommend that scientific communicators carefully consider the kinds of questions their words might be taken to answer and try to avoid phrasing that might be taken to provide unintended answers.

Many people have been enraged lately by the enormous increases in certain generic prescription drugs. But free marketeers defend these prices by arguing that they simply represent what the market will bear, and in a capitalist society there is accordingly nothing wrong with charging them. This paper argues that such a defense is actually contrary to the very principles that free marketeers claim to embrace. These prices are not only unjust and exploitative, but government interference with them would not render (...) the market less free, at least if what it means for a market to be “free” is properly understood. Everyone, even free marketeers with a libertarian or neoliberal bent, should accordingly be against this kind of profiteering. (shrink)

Pragmatism has enjoyed a major resurgence in Anglo-American philosophy over the course of the last decade or two, and Robert Brandom’s work – particularly his 1994 tome Making it Explicit (MIE) – has been at the vanguard of this resurgence (Brandom 1994).2 But pragmatism comes in several surprisingly distinct flavours. Authors such as Hubert Dreyfus find their roots in certain parts of Heidegger and in phenomenologists such as Merleau-Ponty, and they privilege embodied, preconceptual skills as opposed to discursive practices as (...) the basic sites of meaning and agency (Dreyfus 1991; Dreyfus 1992; Todes 2001). With strong inheritances from Dewey and Wittgenstein, Richard Rorty has championed a pragmatism whose core emphasis is on the rejection of transcendental truth and high metaphysical theorizing (Rorty 1982), and this anti-theoretical banner has been taken up by several prominent ethicists, among others. For his part, Brandom, who purports to offer a systematic theory of language and meaning grounded on a foundation of pragmatic normative relationships between speakers, looks back instead to Sellars and Quine for his stripe of pragmatism. Near the start of MIE, he writes: The explanatory strategy pursued here is to begin with an account of social practices, identify the particular structure they must exhibit in order to qualify as specifically linguistic practices, and then consider what different sorts of semantic contents those practices can confer on states, performances, and expressions caught up in them in suitable ways. (Brandom 1994, xiii) Despite his professed pragmatism, Brandom is no foe of high theory or metanarratives, and he is vastly more interested in language and theoretical reason than in the rest of human bodily activity. For Brandom, inferentially articulated discourse forms an autonomous domain of normativity, while our bodily encounters with the world in perception and in action serve as language entry and exit points respectively..

Non-human animals (henceforth, “animals”) are typically regarded as moral patients rather than moral agents. Let us define these terms as follows: 1) X is a moral patient if and only if X is a legitimate object of moral concern: that is, roughly, X is something whose interests should be taken into account when decisions are made concerning it or which otherwise impact on it. 2) X is a moral agent if and only if X can be morally evaluated–praised or blamed (...) (broadly understood)–for its motives and actions. Nothing in (1) and (2), of course, rules out one and the same individual being both a moral agent and a patient. Most humans are both. The notion of a moral agent is typically run together with that of a moral subject: 3) X is a moral subject if and only if X is, at least sometimes, motivated to act by moral considerations. However, (2) and (3) are not equivalent: the motivation for an action is one thing, the evaluation of the action quite another; indeed evaluation is often of motivation. As a matter of practice these are, for obvious reasons, run together. But motivation and evaluation are conceptually distinct. This is a claim that many will regard with surprise. In effect, the bulk of this paper can be regarded as an attempt to defend this claim as it applies to the case of animals. In this section, I merely offer some preliminary remarks in its defense. Suppose that my wife, worn down by the domestic squalor that goes with two young boys, a very large dog, and a slovenly husband, has me (unknowingly) hypnotized. Now, whenever she utters the word ‘Rosebud’, I experience an uncontrollable desire to mop the floor. This desire is, it seems, a motivational state, one that when combined with relevant cognitive states (the belief that this is a mop, the belief that this is a floor, and so on) will, ceteris paribus, result in a certain sort of behavior on my part. This floor-mopping, however, is not something for which I can be praised or blamed. Ex hypothesi, it is the result of a motivational state that is outside my control.. (shrink)

It has been argued in the conservation literature that giving conservation absolute priority over competing interests would best protect the environment. Attributing infinite value to the environment or claiming it is ‘priceless’ are two ways of ensuring this priority (e.g. Hargrove 1989; Bulte and van Kooten 2000; Ackerman and Heinzerling 2002; McCauley 2006; Halsing and Moore 2008). But such proposals would paralyse conservation efforts. We describe the serious problems with these proposals and what they mean for practical applications, and we (...) diagnose and resolve some conceptual confusions permeating the literature on this topic.

The first film adaptation of the story of the unmasking of the insatiable Transylvanian vampire, Count Dracula. The tale unfolds with an awesome eeriness unequalled in later versions.

This book is a philosophical study of the relations between hearing and thinking about music. The central problem it addresses is as follows: how is it possible to talk about what a listener perceives in terms that the listener does not recognize? By applying the concepts and techniques of analytic philosophy the author explores the ways in which musical hearing may be described as nonconceptual, and how such mental representation contrasts with conceptual thought. The author is both philosopher and musicologist (...) and uniquely combines the perspectives of both disciplines. Exploring the philosophical questions of mental representation in the relatively neglected, nonverbal domain of music, this study is a major contribution to the philosophical understanding of music perception and cognitive theory.

Why do people stay together in monogamous relationships? Love? Fear? Habit? Ethics? Integrity? Desperation? In this paper I will consider a rather surprising answer that comes from mathematics. It turns out that cooperative behaviour, such as mutually-faithful marriages, can be given a firm basis in a mathematical theory known as game theory. I will suggest that faithfulness in relationships is fully accounted for by narrow self interest in the appropriate game theory setting. This is a surprising answer because faithful behaviour (...) is usually thought to involve love, ethics, and caring about the well being of your partner. It seems that the game-theory account of faithfulness has no need for such romantic notions. I will consider the philosophical upshot of the game-theoretic answer and see if it really does deliver what is required. Does the game-theoretic answer miss what is important about faithful relationships or does it help us get to the heart of the matter? Before we start looking at lasting, faithful relationships, though, let’s get a feel for how mathematics might be employed to help in matters of the heart. Let’s first consider how mathematics might shed light on dating to find a suitable partner. (shrink)

In a recent article, Dawn Wilson (2021) has argued against single-stage accounts of photography by arguing against the latent photographic images upon which those accounts depend. Concomitantly, she argues that the only viable account of photography is multi-stage. Unlike single-stage accounts, multi-stage accounts do not postulate the existence of photographic images of any kind prior to development. Rather, according to multi-stage accounts, photographs are produced from “photographic registers.” In this Discussion Piece, I defend single-stage accounts by arguing that Wilson’s rejection (...) of latent photographic images is premised on an implausible view of what a latent photographic image is. Given a reasonable interpretation, the latent images described in single-stage accounts just are the photographic registers described in multi-stage accounts. (shrink)

Physicist Perakh critically reviews recent trends towards harmonizing religion and science, and shows that all such approaches are little more than tailoring evidence to fit the desired theory.

As the average age of the population increases, so too do the number of people living with chronic illnesses. With limited resources available, the development of dialogue-based e-health systems that provide justified general health advice offers a cost-effective solution to the management of chronic conditions. It is however imperative that such systems are responsible in their approach. We present in this paper two main challenges for the deployment of e-health systems, that have a particular relevance to dialogue and argumentation: collecting (...) and handling health data, and trust. For both challenges, we look at specific issues therein, outlining their importance in general, and describing their relevance to dialogue and argumentation. Finally, we go on to propose six recommendations for handling these issues, towards addressing the main challenges themselves, that act both as general advice for dialogue and argumentation research in the e-health domain, and as a foundation for future work on this topic.

Formal arguments have proven that avoiding the Repugnant Conclusion is impossible without rejecting one or more highly plausible population principles. To many, such proofs establish not only a deep challenge for axiology, but also pose an important practical problem of how policymaking can confidently proceed without resolving any of the central questions of population ethics. Here we offer deflationary responses: first to the practical challenge, and then to the more fundamental challenge for axiology. Regarding the practical challenge, we provide an (...) overview of recent literature that explores the implications for public policy of the Repugnant Conclusion and related puzzles within population ethics, and shows that there is more commonality in the implications of different population axiologies than is generally recognized. The upshot is that uncertainty about population ethics presents no important problem for policymaking, and the importance of population ethics to policymaking has been overstated. We then turn to more fundamental issues about axiology, and describe a new series of formal proofs that undermine the idea that any plausible axiology could avoid the Repugnant Conclusion, including those that are assumed to avoid it in the literature. The philosophical upshot is that the Repugnant Conclusion cannot plausibly be avoided, and so it is a mistake to assume as a constraint on a plausible axiology that it must be avoided, as is assumed by most of the literature in population ethics, including by all of the fundamental impossibility theorems.

Covenant Theology brings together a number of perspectives on this important feature of Christian tradition from across the theological discipline. Based on four lectures delivered at the University of Liverpool, each address is followed by a response, allowing respected scholars of the field to engage in lively and public debate. The progression from Old Testament to New Testament, then to systematic theology and pastoral theology is intentional, as readers are encouraged to view theology as an integrative discipline rather than a (...) series of fragmented specialisms with little or no relation to one another. With contributions from Stephen Clark, James Dunn, Gary Badcock, and Robin Gill, this academic book combines fresh insights with more traditional approaches and makes for an informed and interesting read. · Lively public debate from key scholars responding to each point. · Discussions from the full length of the Bible. · Practical in its application. · Wide view of theological debate. · Links theology to other disciplines. · Encourages everyone to join the debate.

We have used fMRI to measure responses to chromatic and achromatic contrast in retinotopically defined regions of macaque and human visual cortex. We make four observations. Firstly, the relative amplitudes of responses to color and luminance stimuli in macaque area V1 are similar to those previously observed in human fMRI experiments. Secondly, the dorsal and ventral subdivisions of macaque area V4 respond in a similar way to opponent (L j M)-cone chromatic contrast suggesting that they are part of a single (...) functional area. Thirdly, we find that macaque area V4, like area V1, responds preferentially to chromatic contrast compared to luminance contrast and the degree of preference is strongly influenced by the temporal frequency of the stimulus. Finally, we observe that while macaque V4d is a region on the dorsal surface of the macaque visual cortex that responds robustly to chromatic stimuli, human chromatic responses to identical stimuli are largely confined to the ventral surface suggesting a fundamental difference in the topographical organization of higher visual areas between humans and macaques.

The paper presents an account of the concept of existence that is based on Brentano’s work. In contrast to Frege and Russell, Brentano took ‘exists’ to express a that subsumes objects and explained it with recourse to the non-propositional attitude of acknowledgment. I argue that the core of Brentano’s view can be developed to a defensible alternative to the Frege-Russell view of existence.

This is one of those cases to which Dr. 8 oodhouse's remark applies with all its force, that a method which leads to true results must have its logic — H.S Smith (" On Some of the Methods at Present in Use in Pure Geometry," p. 6) A goodly amount of modern metaphysics has concerned itself, in one form or another, with the question: what attitude should we take in regard to a language whose semantic underpinnings seem less than certain? (...) Since much of standard English is surely of this type, many philosophers have felt driven to extreme and unpalatable resolutions — wholesale rejection of attractive logical rules, radical "antirealism", "minimalism" about truth, and so forth, Scientists, however, have long dealt with analogous foundational insecurities and, under the duress of practicality, have framed a set of shifting attitudes towards language and reasoning that seem far more commonsensical than the extreme positions to which pure philosophy has often been led. Following this lead, this essay will recommend a more nuanced approach to linguistic insecurity that is neither naively optimistic nor mired in the gloomy sloughs of antirealism. (shrink)
