We summarise and respond to the main points made by the commentators on our target article, which concern: whether structural similarity can play a causal role in normal object identification and in neuropsychological deficits for living things, the nature of our structural knowledge of the world, the relations between sensory and functional knowledge of objects, and the nature of our functional knowledge about living things, whether we need to posit a “core” semantic system, arguments that can be marshalled from evidence (...) on functional imaging, the causal mechanisms by which category differences can emerge in object representations, and the nature of our knowledge about categories other than living and nonliving things. We also highlight points raised in our article that seem to be accepted. (shrink)

The traditional definition per genus et differentiam is argued to be cognitively grounded in perception and in order to avoid needless argument, definitions are stipulated to assert boundaries. An analysis of the notion of perspective shows that a boundary is a composite of two distinctions: similarity that includes and difference that excludes. The concept is applied to the type-token distinction and percepts are shown to be the result of a comparison between a token as representing some phenomenon and a type (...) as representing the kind of object the phenomenon might be. The Principle of Connection is proposed as the mental architecture that gives rise to percepts. The value of a percept is shown to be one of Identical, Similar, Different or Contrary and its perceptual aspects represent the cognitive schema of Essence, Quality, Quantity and Relation. The two notions of similarity and difference are claimed to constitute the necessary and sufficient conditions for definitions. Accordingly, the qualitative elements of a definition signify the genus as representing the similarity of the defined entity in terms of others of its kind and the quantitative elements signify the differentia as representing the difference it has from everything else. Paying proper attention to both qualitative and quantitative aspects will enable formulation of definitions that are ‘good’. (shrink)

Critical history is a philosophy of history that highlights the peculiarity and originality of the epistemology and methodology of Bernard Lonergan in the study of history. It is a method of reading the movement of history, through the Lonerganian creative criticism as well as a critical instrument that can help one rise above diverse forms of oversight and bias while working for progress in a human community. It tries to expound on how one can build personal capacities that work for (...) the advantage of the common good. Its precepts can help one achieve self-transcendence and authenticity which are essential in the making of a creative society. It can inspire and create symbols that link one's experience, imagination, rationality, responsibility and affectivity to authentic lived history. It can arouse an intellectual conversion that brings moral revival and can offer insights that help community planners in proposing proper solutions by identifying the actual drivers of progress, decline and re-covery in a society. Critical history creates an intellectual cultivation of mind and character achieved by insight which helps to build an authentic human person and progressive community. Its critical elements can lead to higher viewpoints that rise above prejudices, and these higher viewpoints can move one to integration to higher values. The result will be an authentic subjectivity and emergence of republic of virtues guided by objectivity and sound ethics. (shrink)

Two major functions of the visual system are discussed and contrasted. One function of vision is the creation of an internal model or percept of the external world. Most research in object perception has concentrated on this aspect of vision. Vision also guides the control of object-directed action. In the latter case, vision directs our actions with respect to the world by transforming visual inputs into appropriate motor outputs. We argue that separate, but interactive, visual systems have evolved for the (...) perception of objects on the one hand and the control of actions directed at those objects on the other. This 'duplex' approach to high-level vision suggests that Marrian or 'reconstructive' approaches and Gibsonian or 'purposive-animate-behaviorist' approaches need not be seen as mutually exclusive, but rather as complementary in their emphases on different aspects of visual function.

This paper examines the recent ?deliberative turn? in environmental political thought with particular regard to demands concerning the employment of public reason in democratic deliberation. Working from John Rawls? account of the three essential elements of deliberative democracy, the paper assesses the scope for bringing environmental claims within the remit of public reason, and revisits the ?unfairness to novel reasons? objection against public reason, as articulated by Jeremy Waldron and then criticised by Lawrence Solum. I argue for a contextual (...) view of political justification. The unfairness objection is found to hold in an attenuated form, and disbarring non?public reasons from decisiveness in political justification, even on a wide view of public political culture, imposes an arbitrary unfairness on those, such as environmental activists, seeking to challenge widely shared, but possibly misguided, beliefs.

This paper analyses certain contemporary narratives among Buryats of Russia and China. At issue is the nature of responsibility for the campaigns of terror, in particular the devastation of the Buddhist church in the 1930s. In these accounts political leaders appear as reincarnations, destined to unleash terrible events. Stalin, for example, is said by Buryat Mongol villagers to have been the reincarnation of a Blue Elephant which lived in ancient times in India. I examine local discussions around these stories to (...) suggest that the narrators, themselves having been caught up in the seemingly objective and transparent, yet deeply irrational, accounts of the Party-State, do not (at any rate at present) confront actions in which they were both perpetrators and victims ‘matter-of-factly’. Having been a particular target of the Stalinist all-pervasive organisation of suspicion and punishment, Buryat Buddhists today are creating ‘paranoid narratives’ of their own to explain the repressions - a narrative of displacement, in which the actions attributed to an other (in this case Stalin) are in some way ‘about’ oneself. The reincarnation stories point up the crucial moral issue erased by socialist metahistory, the ethical problem of individual accountability. They are about complicity, for they reveal an uneasy, and probably unconscious, identification with Stalin. (shrink)

Computational methods such as computer simulations, Monte Carlo methods, and agent-based modeling have become the dominant techniques in many areas of science. Extending Ourselves contains the first systematic philosophical account of these new methods, and how they require a different approach to scientific method. Paul Humphreys draws a parallel between the ways in which such computational methods have enhanced our abilities to mathematically model the world, and the more familiar ways in which scientific instruments have expanded our access to the (...) empirical world. This expansion forms the basis for a new kind of empiricism, better suited to the needs of science than the older anthropocentric forms of empiricism. Human abilities are no longer the ultimate standard of epistemological correctness.Humphreys also includes arguments for the primacy of properties rather than objects, the need to consider technological constraints when appraising scientific methods, and a detailed account of how the path from computational template to scientific application is constructed. This last feature allows us to hold a form of selective realism in which anti-realist arguments based on formal reconstructions of theories can be avoided. One important consequence of the rise of computational methods is that the traditional organization of the sciences is being replaced by an organization founded on computational templates.Extending Ourselves will be of interest to philosophers of science, epistemologists, and to anyone interested in the role played by computers in modern science.

The 2015 Paris Agreement set a global warming limit of 2°C above preindustrial levels. Corporations play an important role in achieving this objective, and methods have recently been developed to map global climate targets to specific industries, and individual corporations within those industries. In this article, we assess whether Sustainability ratings capture corporate performance in meeting the 2°C target. We analyze nine rating schemes used by investors and three commonly used in academic studies. Most rating schemes do consider corporate greenhouse (...) gas emissions in their analysis, whereas only a minority scale emissions by factors that have the potential to allow benchmarking against science-based targets. None take the final step of mapping climate indicators against the 2°C target. Furthermore, we find a lack of consistency in the climate change ratings of the databases used in academic studies. These results are concerning in the context of being able to meet global climate change goals. (shrink)

Elements of notation are variables and sentences are sequences of different variables. Both listening and reading are processes, which makes a sentence a stream of variations of a single variable. Thus, a simple sentence is a one-dimensional object, measured along the stream of variation. A sentence with coordinated or subordinated material effectively encodes multiple streams which makes a complex sentence a two-dimensional object with that second dimension measured across the multiple streams. A single symbol does not vary and is therefore (...) a zero-dimensional object. Processes exist in time and the dimensions of notation are therefore abstract dimensions. (shrink)

This paper examines a parallel between Aristotle’s account of phantasia and contemporary psychological models of working memory, a capacity that enables the temporary maintenance and manipulation of information used in many behaviors. These two capacities, though developed within two distinct scientific paradigms, share a common strategy of psychological explanation, Aristotelian Faculty Psychology. This strategy individuates psychological components by their target-domains and functional roles. Working memory and phantasia result from an attempt to individuate the psychological components responsible for flexible thought and (...) are thus implicated in most of our robust cognitive processes, from reading comprehension to problem solving. We then present two novel objections which suggest that these capacities cannot explain our ability to engage in flexible thought. To escape the resultant impasse, we survey alternatives and argue that most promising strategies depend on identifying the behaviors attributed to intelligent thought and action. (shrink)

Category-specific impairments of object recognition and naming are among the most intriguing disorders in neuropsychology, affecting the retrieval of knowledge about either living or nonliving things. They can give us insight into the nature of our representations of objects: Have we evolved different neural systems for recognizing different categories of object? What kinds of knowledge are important for recognizing particular objects? How does visual similarity within a category influence object recognition and representation? What is the nature of our semantic knowledge (...) about different objects? We review the evidence on category-specific impairments, arguing that deficits even for one class of object cannot be accounted for in terms of a single information processing disorder across all patients; problems arise at contrasting loci in different patients. The same apparent pattern of impairment can be produced by damage to different loci. According to a new processing framework for object recognition and naming, the hierarchical interactive theory, we have a hierarchy of highly interactive stored representations. HIT explains the variety of patients in terms of lesions at different levels of processing and different forms of stored knowledge used both for particular tasks and for particular categories of object. Key Words: category-specific deficits; functional imaging; hierarchical models; interactive activation models; neuropsychology; object recognition; perceptual and functional knowledge. (shrink)

This paper is a critical analysis of Putnam’s “consistency objection,” an objection made against a particular reading of Wittgenstein’s philosophy of mathematics (“up-to-us-ism”).

I also show that a companion argument, (the “something more” argument) is unable to overturn this more sophisticated anti-Platonist version of Wittgenstein’s up-to-us-ism. Along the way I try to clarify Wittgenstein’s anti-Plalonist (...) account of mathematics, so that others do not repeat Putnam’s mistake. (shrink)

We present work demonstrating that the nature of an object for our visual system depends on the actions we are programming and on the presence of action relations between stimuli. For example, patients who show visual extinction are more likely to become aware of two objects if the objects fall in appropriate visual locations for a common action. This effect of the action relations between objects is modulated both by the familiarity of the positioning of the objects for action, and (...) by the mere possibility of action (the ‘affordance’) between the objects. In addition, the programming of an action to a part of an object alters the representation of that object, making the ‘part’ into the object selected by the visual system. These results point to object coding being a rather flexible process, affected not only by the perceptual properties of stimuli but also by the relations between these properties and action. We discuss the implications for theories of perception as well as considering why action information, in particular, may be important for perception. (shrink)

Associative memory is the ability to link together components of stimuli. Previous evidence suggests that prior familiarization with study items affects the nature of the association between stimuli. More specifically, novel stimuli are learned in a more context-dependent fashion than stimuli that have been encountered previously without the current context. In the current study, we first acquired behavioral data from 62 human participants to conceptually replicate this effect. Participants were instructed to memorize multiple object-scene pairs and were then tested on (...) their recognition memory for the objects. Importantly, 1 day prior, participants had been familiarized with half of the object stimuli. During the test phase, the objects were either matched to the same scene as during study or swapped with a different object’s scene. Our results conceptually replicated the context-dependency effect by showing that breaking up a studied object-context pairing is more detrimental to object recognition performance for non-familiarized objects than for familiarized objects. Second, we used functional magnetic resonance imaging to determine whether medial temporal lobe encoding-related activity patterns are reflective of this familiarity-related context effect. Data acquired from 25 human participants indicated a larger effect of familiarization on encoding-related hippocampal activity for objects presented within a scene context compared to objects presented alone. Our results showed that both retrieval-related accuracy patterns and hippocampal activation patterns were in line with a familiarization-mediated context-dependency effect. (shrink)

The argument from existence is often used as an attempted justification for our use of animals in commercial practices, and is often put forward by lay-persons and philosophers alike. This paper provides an analysis of the argument from existence primarily within the context of blood-sports (applying the argument to the example of game-birding), and in doing so addresses interesting and related issues concerning the distinction between having a life and living, or worthwhile life and mere existence, as well as issues (...) surrounding our responsibilities to prospective and actual beings. However, my analysis of the argument will go beyond the animal ethics context; it is important that it does so in order to reveal the troublesome implications of the argument and to highlight the sorts of unethical practices it supports. In particular, in applying the argument to a relevant example concerning human beings, I will discuss how the argument from existence could be used to justify the ownership of slaves who were reared for slavery. My objective is to show just how problematic the argument from existence is, with the aim of laying the argument to rest once and for all. (shrink)

Colonius suggests that, in using standard set theory as the language in which to express our computational-level theory of human memory, we would need to violate the axiom of foundation in order to express meaningful memory bindings in which a context is identical to an item in the list. We circumvent Colonius's objection by allowing that a list item may serve as a label for a context without being identical to that context. This debate serves to highlight the value (...) of specifying memory operations in set theoretic notation, as it would have been difficult if not impossible to formulate such an objection at the algorithmic level.

Recognizing that students are fundamentally engaged in a process of learning and self-development, ethical review of sub-doctoral student research should be proportionate to that objective. A student's tutor has the pedagogical role and an ethics committee should not interfere with that relationship other than to seek to avoid harms unforeseen by either the student or tutor. Underpowered or other statistically or methodologically flawed sub-doctoral research should not however, in general, be regarded as ethically concerning. With the proviso that no subject (...) is harmed the student can be allowed to learn such lessons as their mistakes may afford them. (shrink)

This paper examines some possibilities for the laws of nature changing over time. This is done within the context of recent literature on transformational emergence. Transformational emergence is a diachronic account of emergence that does not require the invariance of fundamental objects, properties, and laws. The requirement that no new laws are introduced after the first instance of the universe seems to indicate that all the laws of the universe are present from the outset. By using a dispositional approach to (...) fundamental properties, this restriction can be avoided. An argument appealing to quantitative laws of nature is then used to show that such laws are not, contrary to dispositional essentialism, metaphysically necessary. Further arguments are given to support the possibility of change of laws across time rather than across worlds and why the identity conditions for properties are different in the two cases. The paper is framed by an analysis of John Stuart Mill’s reasons for imposing the invariance requirement on fundamental laws. (shrink)

This paper aims to provide an ethical assessment of the shooting of animals for sport. In particular, it discusses the use of partridges and pheasants for shooting. While opposition to hunting and shooting large wild mammals is strong, game birds have often taken a back seat in everyday animal welfare concerns. However, the practice of raising game birds for sport poses significant ethical issues. Most birds shot are raised in factory-farming conditions, and there is a considerable amount of evidence to (...) show that these birds endure extensive suffering on these farms. Considering the fact that birds do have interests, including interests in life and not suffering, what are the ethical implications of using them for blood sports? Indeed, in the light of the suffering that game birds endure in factory farms, it may be that shooting such birds for sport is more morally problematic than other types of hunting and shooting which many people are often fiercely opposed to, for while it seems plausible to say that some animals may be harmed more by death than others (due to, say, their greater capacities), there may be harms that are worse than death (such as a life of intolerable suffering). The objective of this paper is to assess the ethics of shooting animals for sport, and in particular the practice of raising game birds for use in blood sports, by applying principles commonly used in ethics; specifically the principle of non-maleficence and equal consideration of (like) interests.

To generate coherent behaviour, the brain needs to attend selectively to the many objects that are present in the environment, but this poses several questions. How does the brain know which objects 'belong together'? How does the information from different senses get combined? How does this help to plan and carry out actions? The subject of attentional mechanisms has a long history in cognitive psychology, as it is the key to making sense of the visual world. However, new developments in (...) cognitive neuroscience, and greater understanding of how attention and action are integrated, have transformed the field. This book is the first to bring together leading researchers to discuss the convergence of experimental findings in the following areas: Visual selective attention Attention and perceptual integration Spatial representation and attention Visual attention and action Control of attention Attention, Space, and Action provides a unique combination of perspectives that will appeal to students and researchers from psychology, neuropsychology, neurophysiology, and neuroanatomy.

This book examines the relationship between environmental and democratic thought and the apparent compatibility of ecology and democracy. Although environmental politics is quite rightly seen as a progressive force, it has also featured a strand of extreme right "eco-authoritarianism" and its proponents have sometimes developed controversial positions on such issues as population policy. There have also been a number of situations where radical environmental activists have broken the laws of democratic societies in pursuit of ecological objectives and the book examines (...) this in a number of case studies on biotechnology, genetic engineering and biodiversity. This is a significant contribution to the literature on environmental politics, ecological thought and democracy. (shrink)

In Metaphysics M, Aristotle aims to refute the Platonic view that mathematical objects are substantially prior to sensible things. For Aristotle, mathematical objects are the abstracted attributes of sensible substances required for geometrical analysis and proof. Yet, despite this derivative status of the objects of mathematics, Aristotle insists that they are logically prior to individual substances. This paper examines the distinction between logical and substantial priority, arguing that it underwrites Aristotle’s conception of mathematical necessity and explanation.

The ancients, Friedrich Nietzsche notes, held Homer's objective art and Archilochus's subjective art in equally high esteem. However, if a work of art must be "objective," how are we to understand the subjective artist, who, like Archilochus, produces art from his own subjective experience? Guided by a clue from Schiller's May 18, 1796 letter to Goethe, Nietzsche employs Schopenhauer's theory of music in his consideration of the subjective artist. Turning to Paul Ricoeur's distinction between image as copy and image as (...) fiction, I argue, will assist us in understanding how Nietzsche resolves the problem of the subjective artist. (shrink)

Some philosophers hold that mathematics depends on idealising assumptions. While these thinkers typically emphasise the role of idealisation in set theory, Edmund Husserl argues that idealisation is constitutive of the early Greek geometry that is codified by Euclid. This paper takes up Husserl's idea by investigating three major developments of Greek geometry: Thalean analogical idealisation, Hippocratean dynamic idealisation, and Archimedean mechanical idealisation. I argue that these idealisations are not, as Husserl held, primarily a matter of ‘smoothing out’ sensory reality to (...) produce ideal, ‘perfect’ figures. Rather, Greek geometry depends on assuming some falsehoods – equidistance from a source of illumination, a perfectly unwavering hand, or a machine that weights abstract objects – in order to make complex problems tractable. Although these idealisations were rarely discussed explicitly in antiquity, they can be systematically reconstructed from our extant sources. (shrink)

This paper aims to provide a conceptual analysis of blood-sport as a concept. Through utilising a generalised notion of sport as well as the concept of fair-play, the objective will be to examine whether blood-sports are games and analyse to what extent, if any, blood-sports can be properly called ‘sports’. For the purposes of application and because of the sheer numbers of birds used in the sports-shooting industry, the paper will focus on a discussion of game-birding, but the findings will (...) apply to the practice of ‘blood-sport’ more generally. Work by Sam P. Morris (IJAP, 2014) argues that ‘fair-chase hunting’ can be classified as a game, as well as a sport, although Morris stresses that answers to questions concerning the sport status of hunting do not provide answers to questions regarding the ethics of blood-sports. The author of this paper agrees with Morris regarding the latter point, but pace Morris, she argues that it is doubtful that blood-sport is a game let alone a sport, and that even if one assumes for argument's sake that it is indeed a game, it cannot be properly classed as sport, and that a fair-chase code undermines itself in the context of so called ‘blood-sports’.Footnote1.

There is extensive literature that indicates animals suffer considerably in the practices of factory farming and animal experimentation. In the light of the evidence of this suffering there is an urgent need to answer the question whether our current use of animals is ever morally justifiable. The aim of this thesis is to provide a critical examination of the moral status of animals and of our treatment of animals in these practices. My objective is to assess whether these practices are (...) ever justifiable and whether we have a moral obligation to revise our attitudes towards our use of animals. Animals are often denied moral standing on the basis that they lack certain capacities, such as rationality, language and the ability to think. Further, it is often thought that animals' supposed lack of such capacities could be used as a defence for our use of them in intensive farming and animal experimentation. Thus, in examining the moral status of animals this thesis also examines animals and their capacities in order to determine whether any of the arguments given against the moral standing of animals are sound. In seeking to discover the extent of our moral obligations towards animals and the necessary conditions for moral standing, I will demonstrate that, although animals used in factory farming and experiments do have moral standing, the only consistent course is to extend moral standing to all living things. I will conclude that although the possession of certain much-prized capacities is not necessary for moral standing, many animals do indeed possess such capacities, including the ability to use language. Centrally this thesis calls for a re-evaluation of our attitudes towards animals, particularly in respect of our beliefs about animals used in factory farms and experiments. (shrink)

This chapter identifies four key commitments of green ideology—ecological restructuring, radical democratization, ecological law, and non-violence as a principle of action. It then examines whether these core principles effectively constrain the potential decontestations of other, adjacent principles. Is green ideology a ‘thin’ ideology that is open to co-optation by more developed rivals, or does it stand on more distinctive conceptual territory, placing firm limits on such ideological appropriations? The chapter then assesses some of the challenges that have emerged in recent (...) years from ‘sceptical environmentalism’ and ‘post-ecologism’, whose proponents claim sympathy with the broad objectives of the environmental movement. The chapter concludes by suggesting that such internal diversity represents a maturing of green ideology, but it may also indicate that the version of green ideology that constituted a radical challenge to existing forms of political and economic organization now stands increasingly marginalized.

The hard problem of consciousness is to explain the experience of qualia. But everything gets easier once we realise that what has to be explained is not how qualia can exist as objective entities but rather why the conscious subject should believe that they exist. This essay lays out a programme for doing this. It makes radical proposals as to how the “qualia illusion” is created, and why sustaining this illusion is biologically adaptive.

Why is nature amenable to mathematical description? This question has received attention in the philosophy of science but rarely from a phenomenological perspective. Nevertheless Husserl’s late essay “The Origin of Geometry,” which has received some critical scholarly attention in recent years, contains the beginning of a striking answer. This answer proceeds from Husserl’s main claim in that essay, which he also makes in the Crisis of the European Sciences, that the original meaning of science has been covered over or “sedimented” (...) by concepts that obscure the true intentional core of scientific meaning. In the first three sections of this paper I develop Husserl’s central insights about mathematics in light of two contemporary critiques of his project of “reactivation” of the original, sedimented meaning of science. In the latter two sections, I argue that accepting Husserl’s account of the original meaning and development of science offers a promising explanation of why nature is amenable to mathematics. This explanation hinges on a conception of the objects and methods of mathematics and the mathematized physical sciences as accomplishments, that is, as constituted contents of consciousness.

This book looks anew at the question of nature preservation as public policy. The philosophy of nature preservation has to date focused on whether arguments for nature preservation should be centred on the value of nature itself or derived human benefits. This book argues that this way of thinking about the problem of preservation has been counter-productive for environmental ethics. Instead we need to unite both views around a concern for the irreplaceability of natural objects.

Earlier work has demonstrated that attention is indirectly cognitively malleable by processes of self-association – processes by which agents explicitly associate an item with the self. We extend this work by considering the manipulation of attention to both salient and non-salient objects. We demonstrate that self-association impacts attentional processing not only of non-salient objects, but also regarding salient items known to command attention. This result indicates the flexibility and susceptibility of attentional processing to cognitive manipulation.

Allison's interpretation and defense of Kant's idealism turn on his claim that a clear distinction between two senses of the appearance/reality distinction is crucial to and pervades Kant's thought. These are the empirical and transcendental senses, which distinguish respectively between the ordinary senses of subjective and objective, i.e., that which in my experience I believe belongs solely to my private awareness of things and that which I believe must pertain to everyone's awareness of things because it is an aspect of (...) their being, and the philosophical, or critically reflective, senses of those terms, i.e., that which we want to say about them as a function of the way in which we all experience them and that which sub specie aeternitatis we want to say belongs to things as they are in themselves. The fundamental thrust of Allison's argument is that for Kant the notion of objectivity in the ordinary sense does not imply or entail transcendental objectivity, which had been a supposition common to most of Kant's predecessors. Moreover, Allison's basic criticism of the dominant tradition of interpretation, beginning with Kant's rough contemporaries and extending into the present in the persons of Pritchard, Strawson and Walker, is that their reconstructions of Kantian doctrine and their criticisms of it turn on their inability to see or refusal to acknowledge the presence of this central distinction of Kant's thought. The deep irony pointed out by this study, then, is that just the set of distinctions on which Kant based his solutions to the metaphysical and epistemological problems which he inherited from the Cartesian tradition have been missed by most of his critics, who in turn criticized him for succumbing to all the illusions he thought he had exposed to the light. I believe Allison is correct in this claim, and his strategy of interpretation and defense is both right-minded and fruitful. The key to maintaining the distinction between the two senses of the appearance/reality distinction for Allison is the notion of an epistemic condition, which he defines as "one that is necessary for the representation of an object or an objective state of affairs", and which is to be distinguished from both psychological conditions of knowing and ontological conditions of being. The crux of Allison's argument, then, is to show that and how the notion of an epistemic condition underlies a proper understanding of idealism in the Kantian sense such that it avoids Cartesian metaphysical commitments. This is a formidable task, but one that Allison completes with much more than normal success. (shrink)

Prior work shows that the possibility of action to an object facilitates attentional deployment. We sought to investigate the neural mechanisms underlying this modulation of attention by examining ERPs to target objects that were either congruently or incongruently gripped for their use in the presence of a congruently or incongruently gripped distractor. Participants responded to the presence or absence of a target object matching a preceding action word with a distractor object presented in the opposite location. Participants were faster in (...) responding to congruently gripped targets compared to incongruently gripped targets. There was a reduced N2pc potential when the target was congruently gripped, and the distractor was incongruently gripped compared to the conditions where targets were incongruently gripped or when the distractor, as well as target, was congruently gripped. The N2pc results indicate that target selection is easier when action information is congruent with an object’s use. (shrink)

In this paper I consider Saul Kripke’s famous Humphrey objection to David Lewis’s views on de re modality and argue that responses to this objection currently on the market fail to mitigate its force in any significant way.

An intuitive objection to modal realism is that merely possible worlds and their inhabitants seem to be irrelevant to an analysis of modality. Kripke originally phrased the objection in terms of being concerned about one’s modal properties without being concerned about the properties one’s other-worldly counterparts have. The author assesses this objection in a variety of forms, and then provides his own formulation that does not beg the question against the modal realist. Finally, the author considers two (...) potential answers to the objection so understood and concludes that only one of them has a chance of succeeding. (shrink)

Hazen, Fara, Williamson, and others have objected that counterpart theory generates an unacceptable logic for an actuality operator; I attempt to give a better (...) semantics. (shrink)

Truthmakers, truth conditions, and analyses are closely related, but distinct in rather important ways. A failure to properly appreciate their differences has led to some confusion regarding the role that possible worlds ought to play with respect to modality. Those philosophers who initially proposed the existence of possible worlds were understood as providing an analysis of modality. More recently, many have interpreted them as providing modal truthmakers. But, possible worlds are only suited to serve as truth conditions for modal truths. (...) My goals are as follows: First, to dispel this confusion by detailing the differences between these three concepts. Second, to apply the lesson learned to the famous Humphrey objection against possible worlds. While this objection, if successful, does undermine Lewisian modal realism, it only partially undermines ersatzism, and leaves available a route by which ersatzers may avoid the objection altogether.
