In this article we argue that the concept of need is as vital for moral theory as it is for moral life. In II we analyse need and its normativity in public and private moral practice. In III we describe simple cases which exemplify the moral demandingness of needs, and argue that the significance of simple cases for moral theory is obscured by the emphasis in moral philosophy on unusual cases. In IV we argue that moral theories are inadequate if (...) they cannot describe simple needs-meeting cases. We argue that the elimination or reduction of need to other concepts such as value, duty, virtue or care is unsatisfactory, in which case moral theories that make those concepts fundamental will have to be revised. In conclusion, we suggest that if moral theories cannot be revised to accommodate needs, they may have to be replaced with a fully needs-based theory.

How can we justify partiality to those near to us, such as our own families, friends, neighbours and colleagues, when we could act in much more morally valuable ways by helping others who are merely distant from us? In 1972 Peter Singer used two now-famous examples, Pond and.

In our philosophical tradition and our wider culture, we tend to think of persons as agents. This agential conception is flattering, but in this paper I will argue that it conceals a more complex truth about what persons are. In 1. I set the issues in context. In 2. I critically explore four features commonly presented as fundamental to personhood in versions of the agential conception: action, capability, choice and independence. In 3. I argue that each of these agential features (...) presupposes a non-agential feature: agency presupposes patiency, capability presupposes incapability, choice presupposes necessity and independence presupposes dependency. In 4. I argue that such non-agential features, as well as being implicit within the agential conception, are as apt to be constitutive of personhood as agential features, and in 5. I conclude.

One of the most striking contributions of particularism to moral philosophy has been its emphasis on the relative opacity of the moral scene to the tools of rational analysis traditionally used by philosophers. Particularism changes the place of the philosopher in relation to the moral life, pointing up the limits to what philosophy can do here. The modern moral philosopher who takes particularism seriously no longer has the luxury, endemic in our tradition, of imagining that moral philosophy can be done (...) with only passing illustrative reference to experience, or that the truth about the whole of our moral life may be read of a list of a priori moral principles, whose rationality is underwritten by the mechanistic account of what it is to follow a rule that pre-Wittgensteinian philosophers took for granted.

A threat to women is obscured when we treat “abortion-as-evacuation” as equivalent to “abortion-as-killing.” This holds only if evacuating a fetus kills it. As technology advances, the equivalence will fail. Any feminist account of abortion that relies on the equivalence leaves moral room for women to be required to give up their fetuses to others when it fails. So an account of the justification of abortion-as-killing is needed that does not depend on the equivalence.

Until recently, philosophers tended to be suspicious of the concept of need. Contributors to this volume build on recent work establishing its philosophical importance. David Wiggins, Gillian Brock and John O'Neill propose remedies for some mistakes made in ignoring or marginalising need, for example in need-free theories of rationality or justice. Christopher Rowe, Soran Reader and Sarah Miller highlight insights that emerge when the concept of need is explored through Plato, Aristotle and Kant - and others that emerge when (...) historical work is seen through the lens of need. Jonathan Lowe and Garrett Thomson consider the role need plays in the philosophies of action and mind. Bill Wringe, David Braybrooke and Sabina Alkire debate how our obligations relating to need are best understood and articulated, and how we can best ensure they are fulfilled, exploring for example how talk of need is related to talk of rights, well-being or capability.

Empirical and theoretical foundations for the study of the temporal dynamics of mechanisms contributing to unconscious and conscious processing of visual information; from computational, psychological, neuropsychological, and neurophysiological perspectives.

Aristotle’s account of human needs is valuable because it describes the connections between logical, metaphysical, physical, human and ethical necessities. But Aristotle does not fully draw out the implications of the account of necessity for needs and virtue. The proper Aristotelian conclusion is that, far from being an inferior activity fit only for slaves, meeting needs is the first part of Aristotelian virtue.

Informed by theories of embodied cognition, in the present study, we designed a novel priming technique to investigate the impact of spatial diversity and script direction on searching through concepts in both English and Persian (i.e., two languages with opposite script directions). First, participants connected a target dot either to one other dot (linear condition) or to multiple other dots (diverse condition) and either from left to right (rightward condition) or from right to left (leftward condition) on a computer touchscreen (...) using their dominant hand's forefinger. Following the spatial prime, they were asked to generate as many words as possible using two‐letter cues (e.g., “lo” → “love,” “lobster”) in 20 s. We hypothesized that greater spatial diversity, and consistency with script direction, should facilitate conceptual search and result in a higher number of word productions. In both languages, word production performance was superior for the diverse prime relative to the linear prime, suggesting that searching through lexical memory is facilitated by spatial diversity. Although some effects were observed for the directionality of the spatial prime, they were not consistent across experiments and did not correlate with script direction. This pattern of results suggests that a spatial prime that promotes diverse paths can improve word retrieval from lexical memory and lends empirical support to the embodied cognition framework, in which spatial relations play a crucial role in the conceptual system.

A differential equation with a known solution is transformed by changing both its dependent and independent variables, and the resulting nonlinear differential equation is then compared with the Schrödinger equation. The method is demonstrated using the confluent hypergeometric differential equation and the solutions to hydrogen, SHO and l=0 Morse potential problems are obtained.

A purely algebraic perturbation theory based on deforming the generators of the dynamical group SU(1, 1) is applied to the l = 0 Morse potential problem with $V(r) = V_0 \left[ {e^{ - 2ar} - 2be^{ - ar} } \right]$ . In particular, perturbations of the form $(e^{ - ar} )^N $ and $(e^{ - ar} )^{ - N} $ are treated explicitly.

In the target article Nijhawan speculates that visual perceptual mechanisms compensate for neural delays so that moving objects may be perceived closer to their physical locations. However, the vast majority of published psychophysical data are inconsistent with this speculation.

Needs and Moral Necessity analyses ethics as a practice, explains why we have three moral theory-types, consequentialism, deontology and virtue ethics, and argues for a fourth needs-based theory.

Our aims in this paper are: (1) to indicate some of the many ways in which needs are an important part of the moral landscape, (2) to show that the dominant contemporary moral theories cannot adequately capture the moral significance of needs, indeed, that the dominant theories are inadequate to the extent that they cannot accommodate the insights which attention to needs yield, (3) to offer some sketches that should be helpful to future cartographers charting the domain of morally significant (...) needs, and (4) to consider some anticipated objections to our project and offer some replies.

In this paper I introduce my work in ethics, inviting others to draw on my approach to address the ethical issues that concern them. I set up the Centre for Ethical Philosophy at Durham University in 2007 to plug a puzzling gap in philosophical work to help us help the world. In 1. I set out ethical philosophy. In 2. I consider some implications, for example, that to do good we must pay much more attention to the beings around us, (...) less to ourselves. In 3. I consider the implications for how we should think about war and peace. In 4. I draw out some implications for good political practice. In 5. I consider objections and conclude. (shrink)

Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, and a (...) growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text. Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness. (shrink)

In this paper I argue that cosmopolitanism prohibits war and requires a global approach to criminal justice. My argument proceeds by drawing out some implications of the core cosmopolitan intuition that every human being has a moral status which constrains how they may be treated. In the first part of this paper, I describe cosmopolitanism. In the second part, Cosmopolitanism and War, I analyse violence, consider the standards cosmopolitanism sets for its justification, and argue that war fails to meet them. (...) In the third part, Cosmopolitanism and Criminal Justice, I argue that cosmopolitanism implies a moral obligation to deal justly with human wrongdoing wherever it occurs. Cosmopolitan pacifism follows: war is prohibited, and a consistent global criminal justice system is required. In the fourth part, Why No Cosmopolitan Pacifists?, I consider why cosmopolitans tend not to identify as pacifists, and in the final part, Objections, I discuss some objections. (shrink)

This paper discusses three topics in contemporary British ethical philosophy: naturalisms, moral reasons, and virtue. Most contemporary philosophers agree that 'ethics is natural' - in Section 1 I examine the different senses that can be given to this idea, from reductive naturalism to supernaturalism, seeking to show the problems some face and the problems others solve. Drawing on the work of John McDowell in particular, I conclude that an anti-supernatural non-reductive naturalism plausibly sets the limits on what we can do (...) in ethics. Moral reasons are widely discussed - in Section 2 I describe some of the criteria that used to distinguish moral practical reasons, and note possibilities and problems. Drawing on the work of Elizabeth Anscombe in particular, I suggest that an inclusive, minimalist account of moral reasons may be most fruitful. There has been a revival of philosophical interest in virtue ethics, which I take to be linked to the emergence of non-reductive naturalisms - in Section 3 I describe three points where virtue ethics has an especially significant contribution to make: learning, motivational self-sufficiency, and the question of whether virtues can be reasons. The naturalism of Section 1 constrains the accounts of moral reasons considered in Section 2, and depends upon an account of virtue as learned second nature, discussed in Section 3. (shrink)

Using a metacontrast masking paradigm, prior studies have shown that a target’s color information and form information, can be processed without awareness and that unconscious color processing occurs at early, wavelength-dependent levels in the cortical information processing hierarchy. Here we used a combination of paracontrast and metacontrast masking techniques to explore unconscious color and form priming effects produced by blue, green, and neutral stimuli. We found that color priming in normal observers is significantly reduced when an additional paracontrast mask precedes (...) the target at optimal masking SOAs. However, no reduction of form-priming effects was obtained at similar optimal paracontrast SOAs. We conclude that unconscious color priming depends on an early, wavelength- or stimulus-dependent response of color neurons located at early cortical levels whereas unconscious form priming occurs at later levels.

This chapter presents a selective overview of motion perception, starting with its early philosophical underpinnings. Its role in Gestalt psychology is highlighted including the discovery of the relativity of motion perception and form–motion interactions. The use of reference frames in the computation of motion is illustrated with examples, leading to its current implications for non-retinotopic processing.

Experimental Phenomena of Consciousness is the definitive collection of consciousness phenomena in which awareness emerges as an experimental variable.

BackgroundAcrophobia is a specific phobia characterized by a severe fear of heights. The purpose of the present study was to investigate the efficacy of two therapies that may ameliorate symptoms of acrophobia and anxiety sensitivity, i.e., virtual reality exposure therapy (VRET) and eye movement desensitization and reprocessing (EMDR) therapy with a Waiting List Control Condition (WLCC).MethodsWe applied a three-armed randomized controlled pre-post-test design with 45 female adolescent students. Students who met DSM-5 criteria for acrophobia were randomly assigned to either VRET (...) (N = 15;Mage = 17.26; SD = 1.32), EMDR (N = 15;Mage = 17.15; SD = 1.57), or a WLCC (N = 15;Mage = 17.50; SD = 1.26). The study groups were evaluated one week before the intervention and one week after the last intervention session regarding symptoms of acrophobia (Severity Measure for Acrophobia) and anxiety sensitivity (Anxiety Sensitivity Index).ResultsThe data showed that both the application of VRET and EMDR therapy were associated with significantly reduced symptoms of acrophobia (d = 1.03 for VRET and d = 1.08 for EMDR) and anxiety sensitivity (d = 1.15 for VRET and d = 1.13 for EMDR) in comparison to the Waiting List.LimitationsThe sample consisted only of adolescent women. Due to the recognizable differences between the two interventions, the therapists and the participants were not blind to the conditions.ConclusionThe results suggest that both VRET and EMDR are interventions that can significantly improve symptoms of acrophobia and anxiety sensitivity in female adolescents.Clinical Trial Registrationhttps://www.irct.ir/trial/57391, identifier: IRCT20210213050343N1.
