Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

INTRODUCTION Reopening a Discussion The empiricist-derived epistemology that has directed most social and natural scientific inquiry for the last three ...

If moral status depends on the capacity for consciousness, what kind of consciousness matters exactly? Two popular answers are that any kind of consciousness matters (Broad Sentientism), and that what matters is the capacity for pleasure and suffering (Narrow Sentientism). I argue that the broad answer is too broad, while the narrow answer is likely too narrow, as Chalmers has recently argued by appeal to ‘philosophical Vulcans’. I defend a middle position, Motivational Sentientism, on which what matters is motivating consciousness: (...) any kind of consciousness which presents its subject with reasons for action. (shrink)

The focus of this paper is the process of perfecting agents. There are two views that attempt to explain what perfecting an agent looks like, specifically in the context of temporal requirements. One view claims that it is part of Christian orthodoxy that those destined for heaven will be instantaneously changed upon death from imperfect agents to perfect ones. The other view says that it’s impossible to perform an instantaneous change if the agent wants to maintain their personal identity; an (...) instantaneous change from imperfection to perfection would be tantamount to creating a brand-new person, sufficiently causally disconnected from their previous imperfect self. Instead, this view claims that some form of temporal extension is necessary for the process to be successful. I end up in support of the view that says temporal extension is necessary. (shrink)

Some philosophical theories of consciousness imply consciousness in things we would never intuitively think are conscious—most notably, panpsychism implies that consciousness is pervasive, even outside complex brains. Is this a reductio ab absurdum for such theories, or does it show that we should reject our original intuitions? To understand the stakes of this question as clearly as possible, we analyse the structured pattern of intuitions that panpsychism conflicts with. We consider a variety of ways that the tension between this intuition (...) and panpsychism could be resolved, ranging from complete rejection of the theory to complete dismissal of the intuition, but argue in favour of more nuanced approaches which try to reconcile the two.

This paper responds to two arguments that have been offered against the positing of ‘i-desires’, imaginative counterparts of desire supposedly involved in fiction, pretence, and mindreading. The Introspection Argument asks why, if there are both i-desires and desires, the distinction is so unfamiliar and hard to draw, unlike the relatively clear distinctions between perception and mental imagery, or belief and belief-like imagining. The Accountability Argument asks how it can make sense to treat merely imaginative states as revealing of someone’s psychology, (...) the way we do with responses to fiction. I argue that carefully considering the relationship between other states and their imaginative counterparts sheds light on how we should expect i-desires to differ from desires, and suggests that we may often be in states that are _indeterminate_, in limbo between the two categories. This indeterminacy explains why the distinction is often hard to draw, and why these states can be revealing about us even without (determinately) being real desires. (shrink)

The psychology and phenomenology of our knowledge of other minds is not well captured either by describing it simply as perception, nor by describing it simply as inference. A better description, I argue, is that our knowledge of other minds involves both through ‘perceptual co-presentation’, in which we experience objects as having aspects that are not revealed. This allows us to say that we perceive other minds, but perceive them as private, i.e. imperceptible, just as we routinely perceive aspects of (...) physical objects as unperceived. I discuss existing versions of this idea, particularly Joel Smith’s, on which it is taken to imply that our knowledge of other minds is, in these cases, perceptual and not inferential. Against this, I argue that perceptual co-presentation in general, and mind-perception in particular, yields knowledge that is simultaneously both perceptual and inferential. (shrink)

BackgroundThe return of genetics and genomics research results has been a subject of ongoing global debate. Such feedback is ethically desirable to update participants on research findings particularly those deemed clinically significant. Although there is limited literature, debate continues in African on what constitutes appropriate practice regarding the return of results for genetics and genomics research. This study explored perspectives and ethical considerations of Ugandan genomics researchers regarding the return of genetics and genomics research results.MethodsThis was a qualitative study that (...) employed in-depth interviews. Thirty participants were purposively selected based on their expertise as genomics researchers in Uganda. Data were analysed through content analysis along the main themes of the study using a comprehensive thematic matrix, to identify common patterns arising from the narratives. NVivo software 12 was used to support data analysis.ResultsThe return of genetics and genomics research results was generally acceptable to researchers, and some indicated that they had previously returned individual or aggregate results to participants and communities. The main reasons cited for sharing research results with participants included their clinical utility, actionability and overall benefit to society. Ethical considerations for appropriate return of results included a need for effective community engagement, genetic counselling prior to disclosure of the results, adequate informed consent, and proper assessment of the implications of, or consequences of returning of results. However, the approaches to return of results were perceived as unstandardized due to the lack of appropriate regulatory frameworks.ConclusionsThe return of genetic and genomic research results is generally acceptable to researchers despite the lack of appropriate regulatory frameworks. Ethical considerations for return of genetics and genomics research results are highly divergent, hence the need for national ethical guidelines to appropriately regulate the practice. (shrink)

There is a longstanding debate between those who think that cognition extends into the external environment and those who think it is located squarely within the individual. Recently, a new actor has emerged on the scene, one that looks to play kingmaker. Predictive processing says that the mind/brain is fundamentally engaged in a process of minimising the difference between what is predicted about the world and how the world actually is, what is known as ‘prediction error minimisation’. The goal of (...) this paper is to articulate a novel approach to extended cognition using the resources of PP. After outlining two recent proposals from Constant et al. and Kirchhoff and Kiverstein, I argue that the case for extended cognition can be further developed by interpreting certain elements of the PP story as a “mark of the cognitive”. The suggestion is that when construed at an ‘algorithmic level’ PEM offers a direct route to thinking about extended systems as genuine cognitive systems. On route to articulating the proposal, I lay out the core argument, defend the proposal’s novelty, and point to several of the advantages of the formulation. Finally, I conclude by taking up two challenges raised by Hohwy about the prospects of using PEM to argue for extended cognition. (shrink)

Kant distinguishes between ‘active’ and ‘passive’ citizens and holds that only the former are civilly self-sufficient and possess rights of political participation. Such rights are important, since for Kant state institutions are a necessary condition for individual freedom. Thus, only active citizens are entitled to contribute to a necessary condition for the freedom of each. I argue that Kant attributes civil self-sufficiency to those who are not under the authority of any private individual for their survival. This reading is more (...) textually grounded than the dominant reading, which understands civil self-sufficiency in terms of economic relations alone. I further argue that Kant was interested in relations of authority because he was concerned to eliminate certain forms of corruption. This indicates that Kant’s contested distinction between active and passive citizens was a response to a key problem of any account of public lawgiving. (shrink)

A remarkable but little studied aspect of current evolutionary theory is the use by many biologists and philosophers of theological arguments for evolution. These can be classed under two heads: imperfection arguments, in which some organic design is held to be inconsistent with God's perfection and wisdom, and homology arguments, in which some pattern of similarity is held to be inconsistent with God's freedom as an artificer. Evolutionists have long contended that the organic world falls short of what one might (...) expect from an omnipotent and benevolent creator. Yet many of the same scientists who argue theologically for evolution are committed to the philosophical doctrine of methodological naturalism, which maintains that theology has no place in science. Furthermore, the arguments themselves are problematical, employing concepts that cannot perform the work required of them, or resting on unsupported conjectures about suboptimality. Evolutionary theorists should reconsider both the arguments and the influence of Darwinian theological metaphysics on their understanding of evolution. (shrink)

Shekhinah, the ‘cloud of Yahweh’ in the Bible, a synonym for God’s presence in the rabbinic tradition, and a feminine hypostasis in the Kabbalah, is a popular theological image in contemporary Jewish feminist circles. Shekhinah currently exists in many forms: she is another name for God, feminine, relational, experiential; she is a Goddess and the singular image that is sufficiently adaptable for a diverse range of postmodern feminist interpreters. However, the processes by which Shekhinah became the God/dess of Jewish feminism (...) have not been researched. Therefore, this article tracks the evolution of Shekhinah iconography in the Jewish tradition to gain an understanding of the appeal of these images within the context of Jewish feminism’s quest for an alternative to the androcentric Holy One, blessed be He. The article then traces the extent of Shekhinah theologies engendered by Second, Third-Wave and recent Jewish feminisms concluding that the plurality of contemporary spirituality and the general rejection of ‘systematic’ models of theology are not necessarily problematic. Rather, Shekhinah is argued to be a binding agent for diverse religionists, and one which has become normative to Jewish feminist theology. (shrink)

The best arguments against gun control invoke moral rights—it might be good if there were fewer guns in circulation, but there is a moral right to own firearms. Rather than emphasizing the potential benefits of gun control, this paper meets the best arguments on their home turf. I argue that there simply is no moral right to keep guns on one’s person or in one’s residence. In fact, our moral rights support the mutual disarmament of citizens and police.

If the COVID-19 crisis has brought any benefits, one is the increased attention paid to persons with disabilities in the contexts of clinical medicine and public health. There has been a great deal of insightful discussion since the outbreak about controversial disability issues the pandemic has brought to light. For a population often overlooked in both academic circles and the public square, mere visibility is a victory. There are at least two important respects in which the discussion remains underdeveloped, however.First, (...) much of the work being done has focused on disability considerations in policies governing triage and the rationing of critical care resources under crisis conditions. This is undoubtedly an... (shrink)

Essay exploring the extent to which certain agreements between the police and informants are an affront (both procedurally and substantively) to basic tenets of the liberal tradition in legal and political philosophy.

Israel Scheffler and others have had trouble accepting such drastic theses in my work as that worlds, even old ones, are made by right versions, even new ones, and that two conflicting versions may both be right. But further explication shows how such theses have advantages over the more usual common-sense alternatives.

The biblical, talmudic, midrashic, and mystical traditions, as well as contemporary Jewish feminist theologies, reveal a plethora of Shekhinah images. If tracked historically these readings, while diverse, reveal continuities even across traditions. These include Shekhinah’s ‘immanence’, ‘presence’, ‘exile’, and shared ‘suffering’. Another vital continuity is Shekhinah’s function as protective ‘shield’. Accordingly, in her gendered theology of the Shoah Raphael argues that Shekhinah was ‘present but concealed in Auschwitz because her female face was yet unknowable to women’. Raphael’s selectivist approach appropriates (...) and de-contextualizes texts from the biblical, rabbinic, Zoharic, Lurianic and Hasidic traditions. For Raphael this methodology is necessary given the tradition’s ‘androcentric and patriarchal’ underpinnings. This article’s reading of Shekhinah’s role in the Shoah, however, differs from Raphael’s theology. Indeed, while Raphael acknowledges the historical continuities of Shekhinah’s ‘immanence’, ‘presence’, ‘exile’, ‘suffering’ and protection, she justifiably claims that Auschwitz was not a ‘place of protection’. This is because Raphael understandably refuses associate Shekhinah with the ‘violent and abusive’ God of the ‘masculine Jewish tradition’. Yet a reading of the tradition, ‘warts and all’, reveals that Shekhinah’s presence but inability to protect the ‘victims’ is a break with precedent and requires explanation. This article therefore tracks Shekhinah’s protective role in Jewish tradition and history to suggest, using mystical texts, that the divine presence was sufficiently empowered to intervene in the Shoah and pleaded Israel’s cause, but was powerless because the Holy One, blessed be He refused to ‘consent’. In the process this article hopes to add another layer to Shekhinah’s story and to help ‘bring her out of exile’. (shrink)

I argue that the Formula of Humanity, the principle that we should always treat the humanity of a person as an end in itself and never as a mere means, is a principle of pure practical reason. Insofar as that principle is also the fundamental grounds of morality, it follows, then, that all autonomous rational agents are committed to morality.

Some have argued that God would not allow some person S to be the victim of an evil for the sake of some good G unless G benefits S in particular, not just someone else. Is this true and, if so, is a similar principle true regarding divine hiddenness? That is, would God remain hidden from some person S for the sake of some good G only if G benefits S? I will argue that this principle has a number of (...) exceptions, even in the context of evil, but particularly in the context of divine hiddenness. (shrink)

One of the lessons we ought to have learned from the history of philosophy and science is that it is rarely, if ever, useful in dealing with challenges from a new movement or in distinguishing one’s position from a different school of thought, to “draw a line in the sand” and claim that everything on this side is legitimate and that everything on that side is not, and can therefore be dismissed without serious consideration or discussion. On some analyses, Plato (...) sought to dismiss all of natural science in this way, by claiming that since it dealt with change it can yield at best belief, not knowledge. The logical positivists, building on the work of Hume, tried to use the analytic/synthetic distinction and various forms of verificationism to dismiss as nonsense everything but science, logic, mathematics, and the philosophy of science. Neither of these moves succeeded in banishing what was placed on that side of the line to intellectual never-never land. More recently, critics of creationism have dismissed the views they are attacking as “not science at all” and therefore of neither concern nor interest to the scientific communities. These maneuvers tend to be unsuccessful not just because they rely on distinctions which cannot, in the end, be sustained—or can be drawn and maintained only after all the hard work which they are frequently claimed to make unnecessary has been done—but because they refuse to deal with the specific evidence and arguments advanced by the challengers, bad as those might be.

Recent research on the evolution of religion has focused on whether religion is an unselected by-product of evolutionary processes or if it is instead an adaptation by natural selection. Adaptive hypotheses for religion include direct fitness benefits from improved health and indirect fitness benefits mediated by costly signals and/or cultural group selection. Herein, I propose that religious denominations achieve indirect fitness gains for members through the use of ecologically arbitrary beliefs, rituals, and moral rules that function as recognition markers of (...) cultural inheritance analogous to kin and species recognition of genetic inheritance in biology. This recognition signal hypotheses could act in concert with either costly signaling or cultural group selection to produce evolutionarily altruistic behaviors within denominations. Using a cultural phylogenetic analysis, I show that a large set of religious behaviors among extant Christian denominations supports the prediction of the recognition signal hypothesis that characters change more frequently near historical schisms. By incorporating demographic data into the model, I show that more-distinctive denominations, as measured through dissimilar characteristics, appear to be protected from intrusion by nonmembers in mixed-denomination households, and that they may be experiencing greater biological growth of their populations even in the present day.

At a time of great and increasing interest in the work of Emmanuel Levinas, this volume draws readers into what Levinas described as "philosophy itself"--"a discourse always addressed to another." Thus the philosopher himself provides the thread that runs through these essays on his writings, one guided by the importance of the fact of being addressed--the significance of the Saying much more than the Said. The authors, leading Levinas scholars and interpreters from across the globe, explore the philosopher's relationship to (...) a wide range of intellectual traditions, including theology, philosophy of culture, Jewish thought, phenomenology, and the history of philosophy. They also engage Levinas's contribution to ethics, politics, law, justice, psychoanalysis and epistemology, among other themes. In their radical singularity, these essays reveal the inalienable alterity at the heart of Levinas's ethics. At the same time, each essay remains open to the others, and to the perspectives and positions they advocate. Thus the volume, in its quality and diversity, enacts an authentic encounter with Levinas's thought, embodying an intellectual ethics by virtue of its style. Bringing together contributions from philosophy, theology, literary theory, gender studies, and political theory, this book offers a deeper and more thorough encounter with Levinas's ethics than any yet written.
