Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

A brief article introducing *One True Logic*. The book argues that there is one correct foundational logic and that it is highly infinitary.

A focussed issue of The Reasoner on the topic of 'Infinitary Reasoning'. Owen Griffiths and A.C. Paseau were the guest editors.

Griffiths and Russell D. Gray (1994, 1997, 2001) have argued that the fundamental unit of analysis in developmental systems theory should be a process – the life cycle – and not a set of developmental resources and interactions between those resources. The key concepts of developmental systems theory, epigenesis and developmental dynamics, both also suggest a process view of the units of development. This chapter explores in more depth the features of developmental systems theory that favour treating processes as fundamental (...) in biology and examines the continuity between developmental systems theory and ideas about process in the work of several major figures in early 20th century biology, most notable C.H Waddington.

Diversity is often announced as a solution to ethical problems in artificial intelligence (AI), but what exactly is meant by diversity and how it can solve those problems is seldom spelled out. This lack of clarity is one hurdle to motivating diversity in AI. Another hurdle is that while the most common perceptions about what diversity is are too weak to do the work set out for them, stronger notions of diversity are often defended on normative grounds that fail to (...) connect to the values that are important to decision-makers in AI. However, there is a long history of research in feminist philosophy of science and a recent body of work in social epistemology that taken together provide the foundation for a notion of diversity that is both strong enough to do the work demanded of it, and can be defended on epistemic grounds that connect with the values that are important to decision-makers in AI. We clarify and defend that notion here by introducing emergent expertise as a network phenomenon wherein groups of workers with expertise of different types can gain knowledge not available to any individual alone, as long as they have ways of communicating across types of expertise. We illustrate the connected epistemic and ethical benefits of designing technology with diverse groups of workers using the examples of an infamous racist soap dispenser, and the millimeter wave scanners used in US airport security.

One way in which the practice of inclusion can be actualised in classrooms is through the use of consistent, appropriate differentiated instruction. What remains elusive, however, is insight into what teachers in different contexts think and believe about differentiation, how consistently they differentiate instruction and what challenges they experience in doing so. In the study reported on here high school classrooms in a private and a government school in Lesotho were compared in order to determine teachers’ thoughts and beliefs about (...) differentiation, the frequency of differentiated instruction, and the challenges faced by teachers who implement this inclusive practice. Sampled teachers offered their views on what they understood differentiated instruction to be, the frequency of differentiated instruction, and identified challenges via an administered questionnaire. Data analysis was based on frequency counts and bar charts for comparative purposes. Findings indicate that private school teachers have a higher frequency of differentiated teaching practice, with time constraints indicated as the main challenge. Government school teachers had a lower frequency of differentiation, and identified a lack of resources, and the learner-teacher ratio as challenges, among others. In the study we highlighted the critical role that private schools can play in the national call for the implementation of inclusive teaching in Lesotho, in terms of active collaboration with surrounding government schools. Private schools, with their resources and access to professional development opportunities, can become catalysts in the implementation of inclusive teaching practices. (shrink)

This paper explores the incongruence between white South Africans’ pre- and post-apartheid experiences of home and identity, of which a wave of emigration is arguably a result. Among the commonest reasons given for emigrating are crime and affirmative action; however, this paper uncovers a deeper motivation for emigration using Charles Taylor’s concept of the social imaginary and Martin Heidegger’s concept of dwelling. The skewed social imaginary maintained by apartheid created an unrealistic sense of dwelling for most white South Africans. After (...) 1994, the conditions supporting this imaginary disintegrated. Many white South Africans feel so strong a sense of unease they can no longer dwell in the country. Many try to escape through emigration, but carry unresolved questions of identity and belonging to their new “homes.”. (shrink)

Colonialism’s legacy in South Africa includes persistent economic inequality which, since the country’s universities charge fees, bars many from higher education, perpetuating the marginalisation of those previously disadvantaged by the apartheid regime. In 2015-6, country-wide unrest raged across university campuses, as students protested the yearly cycle of tuition increases under the slogan #FeesMustFall, demanding “free, decolonised education”. Protests ended in December 2017 when the government announced a sliding-scale payment policy alleviating the economic burden for poorer students. This paper sets the (...) #FMF movement and its twin demands within the context of decoloniality, and argues that while free education has been achieved, imagining and implementing decolonised education for South Africa in an increasingly globalised world is a more challenging, elusive goal.

This article offers a prolegomenon for an African feminist philosophy. The prompt for this as an interrogation of Oluwole’s claim that an African feminist philosophy cannot develop until identifiable African worldviews that guide the relationship between men and women have been established. She argues that until there is general agreement about the nature of African philosophy itself, African feminist philosophy will remain impoverished. I critique this claim, unpacking Oluwole’s argument, and examine the contested nature of both African and Western philosophy. (...) Drawing from the work of Mignolo and decolonial thinking, I then argue for the possibility of “epistemic disobedience” concerning the emergence of an African feminist philosophy. Engaging with precolonial African examples which disrupt modern normative gender assumptions and looking at the project of decoloniality, I issue a call for an African feminist philosophy unfettered by the falsely universal claims of modernity/coloniality. My call is for an African feminist philosophy from African loci of enunciation, rooted in the epistemes and experiences of African women. (shrink)

Much mainstream analytic epistemology is built around a sceptical treatment of modality which descends from Hume. The roots of this scepticism are argued to lie in Hume’s (nominalist) theory of perception, which is excavated, studied and compared with the very different (realist) theory of perception developed by Peirce. It is argued that Peirce’s theory not only enables a considerably more nuanced and effective epistemology, it also (unlike Hume’s theory) does justice to what happens when we appreciate a proof in mathematics.

Representationalism (aka intentionalism) has been the most significant weapon in the late twentieth century defence of direct realism. However, although the representationalist objection to the Phenomenal Principle might provide an effective response to the arguments from illusion and hallucination, plausible representationalist theories of perception are, when fleshed-out, incompatible with metaphysical direct realism’s directness-claim. Indeed within cognitive science, direct perception is the avowedly-radical anti-representationalist heterodoxy. Drawing on both the philosophy and cognitive science, we develop a robust argument against representationalist direct realism (...) which does not rest on illusory cases or the notion of an object of immediate awareness. None of the representations so far posited, or in prospect, can supply the content required of a representation in a direct realist theory of veridical perception. (shrink)

Would be fairer to call Peirce’s philosophy of language “extensionalist” or “intensionalist”? The extensionalisms of Carnap and Quine are examined, and Peirce’s view is found to be prima facie similar, except for his commitment to the importance of “hypostatic abstraction”. Rather than dismissing this form of abstraction (famously derided by Molière) as useless scholasticism, Peirce argues that it represents a crucial (though largely unnoticed) step in much working inference. This, it is argued, allows Peirce to transcend the extensionalist-intensionalist dichotomy itself, (...) through his unique triadic analysis of reference and meaning, by transcending the distinction between (as Quine put it) “things” and “attributes”.

For Foucault, Hobbes is important for the transition from sovereignty to governmentality, but he does not always go into great detail how. In “Society Must Be Defended”, Hobbes’s reactions against the political historicism of his time lead him to an ahistorical foundation to the state. In Security, Territory, Population, his contract is emblematic of the art of government still caught in the logic of sovereignty. Management techniques, one of which being inheritance laws like primogeniture, inducing changes in a population’s milieu (...) so that its interest is properly directed allow the art of government to escape this logic. Hobbes supports primogeniture, but its historical position in the common law makes this support unexpected. This article examines the historical context of primogeniture and the reasoning for Hobbes’s support of it in light of Foucault’s claims about him in order to give more precision to those claims. The result is that primogeniture as a law of nature produces the family as an interested unit of the population. Yet this interest is itself historicized, so Hobbes’s attempt to de-historicize politics did not fully succeed. (shrink)

This paper addresses some apparent philosophical tensions between realism and enactivism by means of Charles Peirce’s pragmatism. Enactivism’s Mind-Life Continuity thesis has been taken to commit it to some form of anti-realist ‘world-construction’ which has been considered controversial. Accordingly, a new realist enactivism is proposed by Zahidi (_Phenomenology and the Cognitive Sciences,_ _13_(3), 461–475, 2014 ), drawing on Ian Hacking’s ‘entity realism’, which places subjects in worlds comprised of the things that they can successfully manipulate. We review this attempt, and (...) argue that whilst Zahidi rightly urges enactivists towards ‘internal realism’, he cannot sustain a non-negotiable aspect of realism that is crucial for scientific progress – the claim that multiple subjects inhabit _the same world_. We explore Peirce’s pragmatism as an alternative solution, foregrounding his distinction between existence and reality, and his inquiry-based account of cognition. These theoretical innovations, we argue, fruitfully generalize Zahidi’s _manipulation-based_ enactivist realism to a richer, _inquiry-based_ enactivist realism. We explore how this realism’s pan-species monism about truth encourages and supports the investigation of non-human animal cognition, and conclude by considering some implications of our discussion for long-standing realism debates within pragmatism.

Background. The COVID-19 pandemic necessitated drastic changes to undergraduate medical training at the University of Botswana (UB). To save the academic year when campus was locked down, the Department of Medical Education conducted a needs assessment to determine the readiness for emergency remote teaching (ERT) of the Faculty of Medicine, UB. Objectives. To report on the findings of needs assessment surveys to assess learner and teaching staff preparedness for fair and just ERT, as defined by philosopher John Rawls. Methods. Needs (...) assessment surveys were conducted using Office 365 Forms distributed via WhatsApp, targeting medical students and teaching staff during the 5 undergraduate years. Data were analysed quantitatively and qualitatively. Results. Ninety-two percent (266/289) of students and 73.5% (62/84) of teaching staff responded. Surveys revealed a high penetration of smartphones among students, but poor internet accessibility and affordability in homes. Some teaching staff also reported internet and device insufficiencies. Only WhatsApp was accessible to students and teaching staff. Conclusions. For equitable access to ERT in the future, the surveys revealed infrastructural improvement needs, including wider, stronger, affordable WiFi coverage within Botswana and enhanced digital infrastructures in educational institutions, with increased support for students.

In recent years, a number of US states have adopted laws that require pregnant women to have an ultrasound examination, and be shown images of their foetus, prior to undergoing a pregnancy termination. In this paper, I examine one of the basic presumptions of these laws: that seeing one’s foetus changes the ways in which one might act in regard to it, particularly in terms of the decision to terminate the pregnancy or not. I argue that mandatory ultrasound laws compel (...) women into a position of moral spectatorship and require them to recognise the foetus as a being for whom they are responsible, particularly through empathic responses to ultrasound images. The approach I propose extends the project of a bioethics of the image and highlights the need for a critical analysis of the political mobilization of empathy in discussions of abortion. (shrink)

Mainstream philosophy has seen a recent flowering in discussions of intellectualism which revisits Gilbert Ryle’s famous distinction between ‘knowing how’ and ‘knowing that’, and challenges his argument that the former cannot be reduced to the latter. These debates so far appear not to have engaged with pragmatist philosophy in any substantial way, which is curious as the relation between theory and practice is one of pragmatism’s main themes. Accordingly, this paper examines the contemporary debate in the light of Charles Peirce’s (...) habit-based epistemology. We argue both that knowing-that can be understood as a particularly sophisticated form of knowing-how, and that all bodily competencies—if sufficiently deliberately developed—can be analysed as instantiating propositional structure broadly conceived. In this way, intellectualism and anti-intellectualism are seen to be not opposed, and both true, although Peirce’s original naturalistic account of propositional structure does lead him to reject what we shall call ‘linguistic intellectualism’.

Recent work by Brian Skyrms offers a very general way to think about how information flows and evolves in biological networks — from the way monkeys in a troop communicate, to the way cells in a body coordinate their actions. A central feature of his account is a way to formally measure the quantity of information contained in the signals in these networks. In this paper, we argue there is a tension between how Skyrms talks of signalling networks and his (...) formal measure of information. Although Skyrms refers to both how information flows through networks and that signals carry information, we show that his formal measure only captures the latter. We then suggest that to capture the notion of flow in signalling networks, we need to treat them as causal networks. This provides the formal tools to define a measure that does capture flow, and we do so by drawing on recent work defining causal specificity. Finally, we suggest that this new measure is crucial if we wish to explain how evolution creates information. For signals to play a role in explaining their own origins and stability, they can’t just carry information about acts: they must be difference-makers for acts. (shrink)

We often form intentions to resist anticipated future temptations. But when confronted with the temptations our resolutions were designed to withstand, we tend to revise our previous evaluative judgments and conclude that we should now succumb—only to then revert to our initial evaluations, once temptation has subsided. Some evaluative judgments made under the sway of temptation are mistaken. But not all of them are. When the belief that one should now succumb is a proper response to relevant considerations that have (...) newly emerged, can acting in line with one’s previous intention nonetheless be practically rational? To answer this question, I draw on recent debates on the nature of higher-order evidence and on what rationally responding to such evidence involves. I propose that agents facing temptation often have evidence of “deliberative unreliability”, which they ought to heed even when it is “misleading” (that is, even when their evaluative judgments are in fact proper responses to the relevant considerations then available). Because evidence of deliberative unreliability can “dispossess” agents of normative reasons for evaluative judgments and actions that they would otherwise have, being continent despite judging that one should now succumb can often be more rational than giving in.

Species concepts aim to define the species category. Many of these rely on defining species in terms of natural lineages and groupings. A dominant gene-centred metaconception has shaped notions of what constitutes both a natural lineage and a natural grouping. I suggest that relying on this metaconception provides an incomplete understanding of what constitute natural lineages and groupings. If we take seriously the role of epigenetic, behavioural, cultural, and ecological inheritance systems, rather than exclusively genetic inheritance, a broader notion of (...) what constitutes a natural grouping or lineage may be required. I conclude by outlining an alternative metaconception that is a de-centred metaschema for species. (shrink)

Enactivism has influentially argued that the traditional intellectualist ‘act-content’ model of intentionality is insufficient both phenomenologically and naturalistically, and minds are built from world-involving bodily habits – thus, knowledge should be regarded as more of a skilled performance than an informational encoding. Radical enactivists have assumed that this insight must entail non-representationalism concerning at least basic minds. But what if it could be shown that representation is itself a form of skilled performance? I sketch the outline of such an account (...) from the perspective of Peirce’s pragmatist semiotics, which theorises signs as habits of associating specific cues with appropriate acts and schemas of ensuing experience. Within this framework, I argue, a naturalistic account of propositional structure can be constructed which transcends the symbolic – and in some instances even the linguistic – sphere, and offers new insights regarding the Information Processing Challenge, and the Hard Problem of Content.

Pursuing difficult long-term goals typically involves encountering substantial evidence of possible future failure. If decisions to pursue such goals are serious only if one believes that one will act as one has decided, then some of our lives’ most important decisions seem to require belief against the evidence. This is the puzzle of difficult action, to which I offer a solution. I argue that serious decisions to φ do not have to give rise to a belief that one will φ, (...) but can instead be accompanied by a hope to φ. Hope can motivate and rationalize the various actions that we associate with serious commitment. It can also account for the existence of special pressures to adopt an agential stance toward one’s future. Because hope can be cognitively rational when belief is not, there is no problematic tension between the ideal of epistemic rationality and the phenomenon of difficult action. (shrink)

Robert Brandom’s expressivism argues that not all semantic content may be made fully explicit. This view connects in interesting ways with recent movements in philosophy of mathematics and logic (e.g. Brown, Shin, Giaquinto) to take diagrams seriously - as more than a mere “heuristic aid” to proof, but either proofs themselves, or irreducible components of such. However what exactly is a diagram in logic? Does this constitute a semiotic natural kind? The paper will argue that such a natural kind does (...) exist in Charles Peirce’s conception of iconic signs, but that fully understood, logical diagrams involve a structured array of normative reasoning practices, as well as just a “picture on a page”.

This paper offers both a criticism of and a novel alternative perspective on current ontologies that take race to be something that is either static and wholly evident at one’s birth or preformed prior to it. In it I survey and critically assess six of the most popular conceptions of race, concluding with an outline of my own suggestion for an alternative account. I suggest that race can be best understood in terms of one’s experience of his or her body, (...) one’s interactions with other individuals, and one’s experiences within particular cultures and societies. This embeddedness of human experience has been left out of most discussions of race which tie race to a set of characteristics (either biologically or sociologically defined). To rectify this omission, I articulate what I call the “physiosocial” view of race. This emphasizes the situatedness of human experience, the reciprocal and dynamic nature of the racial identities of individuals and groups. Approaching racial identity in this way entails a union of two historically uncomfortable partners: biological and sociological conceptions of race. If successful, this philosophical stance may illuminate the process of racial self-ascription as well as provide an explanation for the potential changeability of an individual’s racial identity at different times and at different places.

Ethnobotanical research provides ample justification for comparing diverse biological nomenclatures and exploring ways that retain alternative naming practices. However, how (and whether) comparison of nomenclatures is possible remains a subject of discussion. The comparison of diverse nomenclatural practices introduces a suite of epistemic and ontological difficulties and considerations. Different nomenclatures may depend on whether the communities using them rely on formalized naming conventions; cultural or spiritual valuations; or worldviews. Because of this, some argue that the different naming practices may not (...) be comparable if the ontological commitments employed differ. Comparisons between different nomenclatures cannot assume that either the naming practices or the object to which these names are intended to apply identifies some universally agreed upon object of interest. Investigating this suite of philosophical problems, I explore the role grey nomenclatures play in classification. ‘Grey nomenclatures’ are defined as those that employ names that are either intentionally or accidentally non-Linnaean. The classification of the lichen thallus (a symbiont) has been classified outside the Linnaean system by botanists relying on the International Code of Nomenclature for algae, fungi, and plants (ICN). But, I argue, the use of grey names is not isolated and does not occur exclusively within institutionalized naming practices. I suggest, ‘grey names’ also aptly describe nomenclatures employed by indigenous communities such as the Samí of Northern Finmark, the Sherpa of Nepal, and the Okanagan First Nations. I pay particular attention to how naming practices are employed in these communities; what ontological commitments they hold; for what purposes are these names used; and what anchors the community’s nomenclatural practices. Exploring the history of lichen naming and early ethnolichenological research, I then investigate the stakes that must be considered for any attempt to preserve, retain, integrate, or compare the knowledge contained in both academically formalized grey names and indigenous nomenclatures in a way that preserves their source-specific informational content.

This article discusses Heidegger’s interpretation of Parmenides given in his last public lecture ‘The Principle of Identity’ in 1957. The aim of the piece is to illustrate just how original and significant Heidegger’s reading of Parmenides and the principle of identity is, within the history of Philosophy. Thus the article will examine the traditional metaphysical interpretation of Parmenides and consider G.W.F. Hegel and William James’ account of the principle of identity in light of this. It will then consider Heidegger’s contribution, (...) his return to and re-interpretation of Parmenides in his last lecture. Heidegger will, through the Parmenidean claim that ‘Thinking and Being are one’ deconstruct the traditional metaphysical understanding of the principle of identity, and in its place offer a radically different conception of how our relationship, our ‘belonging together’ with Being can be understood.

In its ideal conception, the post-apartheid education landscape is regarded as a site of transformation that promotes democratic ideals such as citizenship, freedom, and critical thought. The role of the educator is pivotal in realising this transformation in the learners she teaches, but this realisation extends beyond merely teaching the curriculum to the educator herself, as the site where these democratic ideals are embodied and enacted. The teacher is thus centrally placed as a moral agent whose behaviour, in the classroom (...) space particularly, should, ideally, represent and communicate the values we aspire to cultivate in post-apartheid South African society generally. Thus, this notion of what teaching encompasses fits broadly into the conception of a “practice” in the sense developed by Alasdair MacIntyre, in that it is a transformative activity the enactment of which not only benefits the practitioner, but also extends to and benefits the broader community as well. Furthermore, practices are grounded in features of social or moral life we hold to be significant and, importantly, it is only through their active cultivation that they can be made tangible and further developed. MacIntyre’s theory of virtue is based on a three-fold interrelationship between practices, how they meaningfully narrate and shape an individual life, and how, in turn, this builds and sustains our moral and social traditions. Using these ideas to analyse post-apartheid South Africa, and the structural transformation paradox it is in, reveals the difficult and complex nature of a society that is in this transitional space. The claim is that attentiveness to practices in the educational space, and to the way they shape and inform moral and social traditions, is necessary to more fully understand and guide this societal transformation.

Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory for groups (...) (n = 74). Assessments were performed at pre-, post-, and 6-month follow-up phases. Results. Meditation awareness training participants demonstrated significant and sustained improvements over control group participants in FMS symptomatology, pain perception, sleep quality, psychological distress, non-attachment (to self, symptoms, and environment), and civic engagement. A mediation analysis found that (1) civic engagement partially mediated treatment effects for all outcome variables, (2) non-attachment partially mediated treatment effects for psychological distress and sleep quality, and (3) non-attachment almost fully mediated treatment effects for FMS symptomatology and pain perception. Average daily time spent in meditation was found to be a significant predictor of changes in all outcome variables. Conclusions. Meditation awareness training may be a suitable treatment for adults with FMS and appears to ameliorate FMS symptomatology and pain perception by reducing attachment to self. (shrink)

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...) expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

Pragmatism’s heartening recent revival (spearheaded by Richard Rorty’s bold intervention into analytic philosophy Philosophy and the Mirror of Nature) has coalesced into a distinctive philosophical movement frequently referred to as ‘neopragmatism’. This movement interprets the very meaning of pragmatism as rejection of metaphysical commitments: our words do not primarily serve to represent non-linguistic entities, but are tools to achieve a range of human purposes. A particularly thorough and consistent version of this position is Huw Price’s global expressivism. We here critically (...) appraise Price’s understanding of a commitment to pragmatism as a rejection of metaphysics, and argue that such rejection is not as easy or desirable as Price claims. First we argue that Price’s global expressivism itself draws on significant metaphysical assumptions (a ‘word-world’ dualism, and a nominalism concerning the meaning of general terms). Then we seek to resolve neopragmatist anxieties about metaphysics by arguing that metaphysics is indispensable for pragmatist philosophizing insofar as it seeks ways for human beings to realise themselves through practices of understanding reality and their place in it. If, as we argue, metaphysics consists in a maximally general inquiry into the nature and structure of reality, to try to block it seems a puzzling exercise in epistemic self-harm. (shrink)

Biological sexes (male, female, hermaphrodite) are defined by different gametic strategies for reproduction. Sexes are regions of phenotypic space which implement those gametic reproductive strategies. Individual organisms pass in and out of these regions – sexes - one or more times during their lives. Importantly, sexes are life-history stages rather than applying to organisms over their entire lifespan. This fact has been obscured by concentrating on humans, and ignoring species which regularly change sex, as well as those with non-genetic or (...) facultatively genetic sex determination systems. But the general point applies equally to humans. Assigning sexes to pre-reproductive life history stages involves ‘prospective narration’ – classifying the present in terms of its anticipated future. Assigning sexes to adult stages of non-reproductive castes or non-reproductive individuals is a complex matter whose biological meaning differs from case to case. The chromosomal and phenotypic ‘definitions’ of biological sex that are contested in philosophical discussions of sex are actually operational definitions which track gametic sex more or less effectively in some species or group of species. Neither ‘definition’ can be stated for species in general except by defining them in terms of gametic sex. The gametic definition of sex also features in widely accepted models which explain why two biological sexes – either in separate individuals or combined in hermaphroditic individuals - are almost universal in multicellular species. Finally, the fact that a species has only two biological sexes does not imply that every member of the species is either male, female or hermaphroditic, or that the sex of every individual organism is clear and determinate. The idea of biological sex is critical for understanding the diversity of life, but ill-suited to the job of determining the social or legal status of human beings as men or women. (shrink)

Questionable research practices are a well-recognized problem in psychology. Coding bias, or the tendency of review studies to disproportionately cite positive findings from original research, has received comparatively little attention. Coding bias is more likely to occur when original research, such as neuroimaging, includes large numbers of effects, and is most concerning in applied contexts. We evaluated coding bias in reviews of structural magnetic resonance imaging (sMRI) studies of PCL-R psychopathy. We used PRISMA guidelines to locate all relevant original sMRI (...) studies and reviews. The proportion of null-findings cited in reviews was significantly lower than those reported in original research, indicating coding bias. Coding bias was not affected by publication date or review design. Reviews recommending forensic applications—such as treatment amenability or reduced criminal responsibility—were no more accurate than purely theoretical reviews. Coding bias may have contributed to a perception that structural brain abnormalities in psychopaths are more consistent than they actually are, and by extension that sMRI findings are suitable for forensic application. We discuss possible sources for the pervasive coding bias we observed, and we provide recommendations to counteract this bias in review studies. Until coding bias is addressed, we argue that this literature should not inform conclusions about psychopaths' neurobiology, especially in forensic contexts. (shrink)

I begin, haltingly, and the individual begins, for John Stuart Mill, with an impulse. My impulse, in terms of Mill, is to ask after power and energy in his On Liberty. There, impulses are desires and those of the “Strong” variety are synonymous with energy (Mill 2002, p. 62). An individual with their own impulses has character and one with strong impulses governed by a strong will has energetic character. One without them has no character. I begin haltingly, in part, (...) because, insofar as my impulse is directed toward power and energy, I am unsure as to the will that may or may not govern it, whether this question reveals or begins to reveal something of my character, its degree of energy, or the lack thereof.

This paper will reflect on the possibility of epistemic decolonization, particularly in terms of curriculum, as a transformative educational process in the context of the South African university, and with respect to my own positionality. The argument will centre around two difficult interdependent positions. On the one hand I will argue for the university’s task as transformational, even offering, via Cornel West, the ‘salvific’ possibility that knowledge offers those who seek it. To develop this claim, I will draw on and (...) develop the notion of paideia though the work of Plato and Heidegger.On the other hand, within the postcolonial African university, the question of decolonization in the tertiary space cannot be elided, particularly since the 2015 #RhodesMustFall and #FeesMustFall movements. The university is a powerful colonial relic, and it can be used to reinforce and perpetuate epistemic violence through unreflective or unconscious pedagogical and curriculum decisions. Here I draw on decolonial thinkers such as Santos, Mignolo, Maldonado-Torres, and Mbembe: I argue for a reckoning with the forces of coloniality, and advocate for epistemic justice and criticality, as part of the decolonizing project. In conclusion, working with ideas from Cornel West, I argue to reconcile paideia, as the ‘turning of the soul’, with the decolonizing African university. (shrink)

Mindfulness is a form of meditation that derives from Buddhist practice and is one of the fastest growing areas of psychological research. Studies investigating the role of mindfulness in the treatment of behavioural addictions have – to date – primarily focused on gambling disorder.

Although preliminary findings indicate that there are applications for mindfulness approaches in (...) the treatment of gambling disorder, further empirical and clinical research utilizing larger-sample controlled study designs is clearly needed.

It seems possible to know that a mathematical claim is necessarily true by inspecting a diagrammatic proof. Yet how does this work, given that human perception seems to just (as Hume assumed) ‘show us particular objects in front of us’? I draw on Peirce’s account of perception to answer this question. Peirce considered mathematics as experimental a science as physics. Drawing on an example, I highlight the existence of a primitive constraint or blocking function in our thinking which we might (...) call ‘the hardness of the mathematical must’. (shrink)

Analytic philosophy took a wrong turn when it rehabilitated direct realism. From the perspective of cognitive science, it seems that we can have the directness-claim or the realism-claim but not both together. Up until the mid-1900s the vast majority of philosophers dismissed direct realism as hopelessly naïve, but by the close of the century it had become the orthodoxy within analytic philosophy.

I defend the thesis that friendship can constitutively require epistemic irrationality against a recent, forceful challenge, raised by proponents of moral and pragmatic encroachment. Defenders of the “encroachment strategy” argue that exemplary friends who are especially slow to believe that their friends have acted wrongly are simply sensitive to the high prudential or moral costs of falsely believing in their friends’ guilt. Drawing on psychological work on epistemic motivation (and in particular on the notion of “need for closure”), I propose (...) a different picture of what friendship requires in the doxastic realm. I argue that contrary to what the encroachment strategy suggests, exemplary friends’ belief formation ought not be guided by a concern with accuracy or error avoidance, but instead by a need to avoid a “specific closure” – namely, a need to avoid concluding in their friends’ guilt. I propose that exemplary friendship often generates a defeasible, doxastic obligation to exemplify such a need, despite its inherent corrupting effects on exemplary friends’ epistemic faculties.

This article addresses a debate in Descartes scholarship over the mind-dependence or -independence of time by turning to Merleau-Ponty’s "Nature" and "The Visible and the Invisible." In doing so, it shows that both sides of the debate ignore that time for Descartes is a measure of duration in general. The consequences to remembering what time is are that the future is shown to be the invisible of an intertwining of past and future, and that historicity is the invisible of God.

Book review of Richard A. Richards' The Species Problem: A Philosophical Analysis.

It is now widely accepted that a scientifically credible conception of human nature must reject the folkbiological idea of a fixed, inner essence that makes us human. We argue here that to understand human nature is to understand the plastic process of human development and the diversity it produces. Drawing on the framework of developmental systems theory and the idea of developmental niche construction we argue that human nature is not embodied in only one input to development, such as the (...) genome, and that it should not be confined to universal or typical human characteristics. Both similarities and certain classes of differences are explained by a human developmental system that reaches well out into the 'environment'. We point to a significant overlap between our account and the ‘Life History Trait Cluster’ account of Grant Ramsey, and defend the developmental systems account against the accusation that trying to encompass developmental plasticity and human diversity leads to an unmanageably complex account of human nature.

The conceptualisation of schooling is often based on “ideal children” in “ideal situations.” However, in determining the level of participation for children who are considered vulnerable in schooling, it is important to understand the lived experiences of these children. In this study, migrant children (particularly undocumented ones) in South Africa are the focus, and their lived experiences were considered through reflections from their parents and teachers. Data were collected using semi-structured interviews, and analysed using a constant comparative method of qualitative (...) analysis within a grounded theory approach. The study found that challenges affecting migrant children’s schooling include the lack of documentation, language barriers, issues of transition and adaptation (discrimination), and the inability to access further education. Strategies were identified to address the challenges, including schools liaising with the Department of Home Affairs, implementing cultural diversity programmes within the school, and through deliberate inclusive programmes.

This essay compares Maurice Merleau-Ponty's notion of the flesh with Judith Butler's concept of primary vulnerability in terms of their helpfulness for developing an intersubjective ontology. It compares the flesh with Butler's more recent concept of primary vulnerability insofar as she sees both as useful for intersubjective ontology. The hiatus of the flesh is that which spans between self and world and opens Merleau-Ponty's thought onto an intersubjective ontology. While Butler's discussion of vulnerability as a primary condition of human existence (...) also makes this concept intersubjective, her understanding of violence as articulated through vulnerability makes this a more helpful concept for intersubjective ontology than the flesh. While many discussions of an intersubjective way of life focus almost exclusively on its positive possibilities, almost to the exclusion of violence altogether, the understanding of violence Butler presents through primary vulnerability helps us to discern whether a violation is benign or malign. In turn, this fuller understanding of violence lets primary vulnerability open onto an ethical imperative of reconciliation, but a reconciliation of what is never whole. (shrink)

Discussions of psychiatric nosology focus on a few popular examples of disorders, and on the validity of diagnostic criteria. Looking at Anorexia Nervosa, an example rarely mentioned in this literature, reveals a new problem: the DSM has a strict taxonomic structure, which assumes that disorders can only be located on one branch. This taxonomic assumption fails to fit the domain of psychopathology, resulting in obfuscation of cross-category connections. Poor outcomes for treatment of Anorexia may be due to it being pigeonholed (...) as an Eating Disorder, when a disturbance of body perception may be a more central symptom than food restriction. This paper explores the possibility of restructuring the DSM taxonomy to allow for a pluralist classification of disorders. This change could improve treatment and research without requiring any changes to diagnostic criteria. (shrink)

Feminists note an association of arguing with aggression and masculinity and question the necessity of this connection. Arguing also seems to some to identify a central method of philosophical reasoning, and gendered assumptions and standards would pose problems for the discipline. Can feminine modes of reasoning provide an alternative or supplement? Can overarching epistemological standards account for the benefits of different approaches to arguing? These are some of the prospects for argumentation inside and outside of philosophy that feminists consider. -/- (...) The further concern is that the academic study of argumentation – in philosophy and other disciplines – has failed to account for the type of reasoning needed for social justice movements. What resources for addressing these concerns can be found in informal logic and interdisciplinary argumentation theory? Since part of the perceived problem derives from assuming that arguing is a contest, are more collaborative epistemological frameworks better? Can regular politeness or civility hedge against undesirable tendencies of argumentation? Can “critical thinking” pedagogy involving argument educations answer the needs of social justice? (shrink)

This article investigates some of the constraining factors experienced by 16 school-going mothers in the Okalongo circuit, Namibia. This was a qualitative phenomenological study, conducted through in-depth individual interviews, focus group discussions, and reflective journals with 16 school-going mothers between the ages of 17 and 20, purposively selected from three different public rural schools. This qualitative, phenomenological study analyses, through feminist and intersectionality theory, the lived experiences of these young mothers as they encounter the traditional, patriarchal attitudes and practices of (...) the Ovambadja community because these girls fell pregnant before their formal, cultural initiation. The article documents, through the voices of the young women themselves, the numerous constraints they experienced and overcame in their determination to complete their schooling. The findings show that, aside from the deeply held destructive patriarchal beliefs that significantly constrain and harm the mother-learners, the Namibian Learners Pregnancy Policy, which is intended to protect and ensure pregnant learners and motherlearners complete their schooling, is not being properly or effectively implemented. The study recommends an increase in efforts at the national level in Namibia to raise awareness among members of parliament, school administrators and principals, and all policymakers to develop better monitoring systems that will improve policy implementation in schools.

Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...) illustrated by showing how life-history theory clarifies the status of so-called diseases of old age. The selected effect account of function deserves a more prominent place in the philosophy of medicine than it currently occupies. _1_ Introduction _2_ Biostatistical and Selected Effect Accounts of Function _3_ Objections to the Selected Effect Account _3.1_ Boorse _3.2_ Kingma _3.3_ Hausman _3.4_ Murphy and Woolfolk _4_ Problems for the Biostatistical Account _4.1_ Schwartz _5_ Analysis versus Explication _6_ Explicating Dysfunction: Life History Theory and Senescence _7_ Conclusion.

A review of the life and work of the Australian philosopher Huw Price.

Although most contemporary philosophers of language hold that semantics and pragmatics require separate study, there is surprisingly little agreement on where exactly the line should be drawn between these two areas, and why. In this paper I suggest that this lack of clarity is at least partly caused by a certain historical obfuscation of the roots of the founding three-way distinction between syntax, semantics and pragmatics in Charles Peirce’s pragmatist philosophy of language. I then argue for recovering and revisiting these (...) original roots, taking indexicality as a case-study of how certain questions connected with the distinction which are currently considered complex and difficult may be clarified by a ‘properly pragmatist pragmatics’. Such a view, I shall argue, upends a certain priority usually accorded to semantics over pragmatics, teaching that we do not work out what terms mean in some abstract overall sense and then work out to what use they are being put; rather, we must understand to what use terms are being put in order to understand what they mean.
