Three arguments for the thesis that sex is socially constructed are examined and rejected. No such argument could succeed, because sex is not socially constructed.

argument fails, and the purpose of this note is to bring out that failure. The view in question which Heck calls the Hybrid Vie~istinguishes between the meanings of names and the contents of beliefs which are expressible using names. According to the Hybrid View the meaning of a name is its referent: names do not have senses. Thus (a) "George Orwell wrote 1984" means the same as (b) "Eric Blair wrote 1984". However, the Hybrid View tells a different story about (...) the beliefs one expresses when one utters (a) or (b). The content of a belief expressed using a sentence that contains a name has more to it than just the referent of the name and whatever properties the sentence ascribes to the name's referent. There is.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Humanist History of Mathematics?Regiomontanus's Padua Oration in ContextJames Steven ByrneIn the spring of 1464, the German astronomer, astrologer, and mathematician Johannes Müller (1436–76), known as Regiomontanus (a Latinization of the name of his hometown, Königsberg in Franconia), offered a course of lectures on the Arabic astronomer al-Farghani at the University of Padua. The only one of these to survive is his inaugural oration on the history and utility (...) of the mathematical arts.1 Regiomontanus tells his audience that the purpose of the oration is torelate first the origin of our arts, and among which nations they first began to be cultivated, in what way they were at last translated from various foreign tongues into Latin, which of our ancestors were famed in these disciplines, and to whom in our lifetimes recognition should be granted.2To this end, he offers a history of the quadrivial arts (arithmetic, geometry, music, and astronomy) and other important mathematical disciplines from [End Page 41] antiquity to his own time, praises their utility, and exhorts his audience to revive the languishing study of mathematics at Padua. Astrology, a discipline with which Regiomontanus himself was closely associated, is singled out for particular praise.Traditionally, Regiomontanus's Padua oration has been seen through the lens of its rather obvious humanism. In particular, the Padua oration has come to be understood as the rhetorical embodiment of the fifteenth-and-sixteenth-century revival of ancient (Greek) mathematics. Just as this revival is inextricable from the rise of humanism, so Regiomontanus has come to be seen as an exemplar of humanist mathematics.3 It is the aim of this paper to examine the Padua oration in the context both of contemporary humanist rhetoric and of Regiomontanus's own intellectual background in order to argue that, while the oration is stylistically consistent with humanist norms, the vision of mathematics presented in it is also deeply grounded in the university mathematical curriculum and in Regiomontanus's own reading of mathematical texts.Regiomontanus was educated primarily at the University of Vienna (he was also briefly at the University of Leipzig), where he enrolled in 1450, completed his baccalaureate in 1452 and became a master in 1457.4 He remained at Vienna until 1461, when the death of his friend and teacher Georg Peurbach prompted him to travel to Italy with his patron, Cardinal Bessarion.5 In Regiomontanus's day Vienna was probably the most important of the German universities, rivaled only by Prague, whose prestige had declined after it was stripped of its theology faculty in the aftermath of the Hussite Wars.6 The curriculum at the University of Vienna was modeled [End Page 42] after that of Paris, and Parisian scholars played a major role both in its founding in 1365 and in its re-establishment (this time with a theology faculty) in 1384.7Most importantly for the purposes of this paper, the Viennese mathematical curriculum of Regiomontanus's day included all of the traditional authorities taught at Paris in the fourteenth century. For arithmetic and algebra, various "algorisms" (prose or poetry instructions for carrying out arithmetical operations that often also included a small amount of number theory) were the basic texts, supplemented in the fourteenth century by the Quadripartitum numerorum of Jean de Murs. Jordanus de Nemorare's De numeris datis and al-Khwarizmi's Algebra were common sources for those engaged in more advanced studies (i.e., they were not normally the subject of ordinary lectures, but were readily available to interested students, and would perhaps have been the subject of occasional extraordinary lectures). Euclid's Elements, supplemented by the commentaries of Pappus and Campanus, was the central text for geometry, and a number of medieval texts on practical and speculative geometry were in circulation as well. For astronomy, the Sphere of Sacrobosco and the Theorica planetarum were the most commonly used teaching texts, sometimes supplemented by al-Farghani's Elements of Astronomy (the subject of Regiomontanus's Padua lectures). Advanced students could read numerous more specific treatises by Arabic and Latin authors. For optics, the Perspectiva communis of John Peckham was the most common basic text, with texts... (shrink)

The human body has come to be seen as forever susceptible to both external and internal hazards, which in many circumstances require immediate, heroic, and expensive intervention. In response to this, there has been a shift from a treatment‐based healthcare model to one of prevention wherein nurses play an integral role by identifying and assessing risks for individuals, communities, and populations. This paper uses Deborah Lupton’s outline of the spectrum of risk and applies the theoretical works of Foucault and Plato (...) to demonstrate the means by which nurses maintain social order by identifying and counselling risk takers. It also utilizes the work of Deleuze and Guattari to illustrate how Plato’s framework for creating social order through the creation of the good citizen can be viewed as a micro‐fascist system, which has been adopted wholeheartedly by preventative health professionals. The goal of this paper is to present an alternate understanding of risk to provide nurses and other healthcare professionals with a non‐traditional appreciation of certain aspects of their practice as researchers and clinicians.

Philosophers are accustomed to thinking about human existence as finite and deathbound. Anne O'Byrne focuses instead on birth as a way to make sense of being alive. Building on the work of Heidegger, Dilthey, Arendt, and Nancy, O'Byrne discusses how the world becomes ours and how meaning emerges from our relations to generations past and to come. Themes such as creation, time, inheritance, birth and action, embodiment, biological determinism, and cloning anchor this sensitive and powerful analysis. O'Byrne's (...) thinking advances and deepens important discussions at the intersections of feminism, continental philosophy, philosophy of religion, and social and political thought. (shrink)

Edited by a team of four leading philosophers, The Norton Introduction to Philosophy introduces students to contemporary perspectives on major philosophical issues and questions. This text features an impressive array of readings, including 25 specially-commissioned essays by prominent philosophers. A student-friendly presentation, a handy format, and a low price make The Norton Introduction to Philosophy as accessible and affordable as it is up-to-date.

In this article I use Baudrillard’s claim that systems of exchange are ontologically and historically prior to systems of production, and Arendt’s understanding of birth as the arrival of something both quite familiar and quite new into the world as the starting-points for a theory of labour as relation. Such a theory has the virtue of avoiding the problem, found in Marx, Arendt and elsewhere, that labour is both a vital feature of being human and yet a drudgery that will (...) be absent from post-revolutionary society (in the case of Marx) or strictly relegated to the private realm (for Arendt). It also involves repositioning the work of social reproduction – of which women’s labour in giving birth is exemplary – as paradigmatic. (shrink)

In this study on deduction, the authors argue that people reason by imagining the relevant state of affairs, ie building an internal model of it, formulating a tentative conclusion based on this model and then searching for alternative models.

The COVID-19 pandemic has prompted unprecedented global disruption. For medical schools, this has manifested as examination and curricular restructuring as well as significant changes to clinical attachments. With the available evidence suggesting that medical students’ mental health status is already poorer than that of the general population, with academic stress being a chief predictor, such changes are likely to have a significant effect on these students. In addition, there is an assumption that these students are an available resource in terms (...) of volunteerism during a crisis. This conjecture should be questioned; however, as those engaging in such work without sufficient preparation are susceptible to moral trauma and adverse health outcomes. This, in conjunction with the likelihood of future pandemics, highlights the need for ‘pandemic preparedness’ to be embedded in the medical curriculum. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Comments on “Moral Complicity in Induced Pluripotent Stem Cell Research”W. Malcolm Byrnes, Ph.D. and Edward J. FurtonIn his article titled “Moral Complicity in Induced Pluripotent Stem Cell Research,” Mark T. Brown (2009) unfortunately mischaracterizes my ethical analysis of the use of induced pluripotent stem (iPS) cells for replacement therapies, or treatments (Byrnes 2008). In my paper, which Brown cites, I argue that, just as it is ethically acceptable for (...) parents to allow their children and themselves to be immunized using vaccines produced by cell lines derived from human fetuses aborted in the past, it is also acceptable for persons in the future to benefit from treatments that use iPS cells validated using human embryonic stem (ES) cell lines [End Page 202] derived in the past. The assumption I make is that iPS cells would have to be shown to be functionally equivalent to human ES cells—i.e., validated—before they could be used for cell replacement treatments. (If it turns out that this assumption is incorrect, and primate or even mouse ES cells can be used for the validation, then all residual ethical problems will disappear and there will be no ethical problems whatsoever associated with iPS cells.) I wrote:... [I]n both cases, the origin of the treatment is in a one-time event: either the one-time use of aborted fetuses to obtain cell lines (e.g., MRC-5 and WI- 38) to grow weakened virus strains for vaccine production, or the one-time destruction of human embryos to validate iPS cells, which then effectively replace embryonic stem cells. In the latter case, if no additional embryonic stem cell lines are derived, then derivation of the existing lines could be considered a “one-time” event in the past, albeit an event that extended over a several-year period(Byrnes 2008, p. 287, emphasis added).Note the phrase “if no additional embryonic stem cell lines are derived.” The derivation of ES cell lines inherently involves destruction of embryos; indeed, that is why many people, including me, are opposed to human ES cell research. In my article, I am arguing that, if no additional ES cell lines are derived, then no additional human embryos will be destroyed, and the destruction of human embryos will lie in the past. In this case, embryo destruction could be considered a past event, just as the abortion of a human fetus from which vaccine-producing cell lines were derived is a past, albeit tragic, event.In the process of building his argument that proponents of iPS cell research are morally complicit in embryo destruction, Brown (2009, p. 15) casts me as being in favor of the “derivation of new embryonic stem [cell lines].” This is the exact opposite of my position. In fact, I am opposed to further destruction of human embryos. I believe that the hundreds of ES cell lines already in existence are more than sufficient to validate iPS cells and so no additional lines need to be derived. This means that no additional human embryos will need to be destroyed.Apparently based on the misperception that I support future destruction of human embryos, Brown concludes that “Byrnes’s endorsement of ongoing iPSC validation studies would seem to implicate him and those who follow his lead in formal and material complicity in what they perceive as moral evil” (p. 16). He writes that “explicit formal complicity would attach because he [Byrnes] knowingly and intentionally recommends that embryos be killed in order to facilitate a transition to a future in which no more embryos need be destroyed” (p. 16). Additionally, my “followers” and I would be guilty of “proximate material complicity” as well as “remote material complicity” (p. 16). Unfortunately, this broad condemnation is based on a misconception of my actual position.An additional problem involves Brown’s use of a quotation he attributes to me: [End Page 203]Once embryonic stem cells are used to successfully validate iPS cells, they will no longer be needed and their association with iPS cells will lie in the past. Is there not an element of sadness and resignation in accepting something (iPS cells) associated with an unjust act (destruction of an... (shrink)

This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals (if) and disjunctions (or), unlike those in logic, refer to conjunctions of epistemic possibilities that hold in default of information to the contrary. Various factors such as general knowledge can modulate these interpretations. New information can always override sentential inferences; that is, reasoning in daily life is defeasible (...) (or nonmonotonic). The theory is a dual process one: It distinguishes between intuitive inferences (based on system 1) and deliberative inferences (based on system 2). The article describes a computer implementation of the theory, including its two systems of reasoning, and it shows how the program simulates crucial predictions that evidence corroborates. It concludes with a discussion of how the theory contrasts with those based on logic or on probabilities. (shrink)

For medical schools, the COVID-19 pandemic necessitated examination and curricular restructuring as well as significant changes to clinical attachments. With the available evidence suggesting that medical students’ mental health status is already poorer than that of the general population, with academic stress being a chief predictor, such changes are likely to have a significant effect on these students. This online, cross-sectional study aimed to determine the impact of COVID-19 on perceived stress levels of medical students, investigate possible contributing and alleviating (...) factors, and produce recommendations for medical schools to implement during future healthcare emergencies. The majority of respondents reported levels of stress ranging from moderate to extreme. Higher levels of stress were significantly associated with female gender and international status. A significant association was also noted between reported stress and the transition to online learning and online assessment formatting, concerns for personal health and for the health of family members. Students who reported higher stress levels were less confident in their government’s management of the crisis. Additionally, students who reported lower stress agreed highly that their medical school had an appropriate response to the crisis, had provided sufficient information regarding the crisis, that they trust their school in handling the continuing of their education and that their school had appropriate plans in place to support the continuing of education.

Book review for 50 Concepts for a Critical Phenomenology, edited by Gail Weiss, Anne V. Murphy, and Gayle Salamon (2020).

From its earliest beginnings, political thought has grappled with the problem of those who both do and do not belong to the city, those who cannot be exactly included or excluded, that is to say, with the problem of difference. Most often this emerges first as the problem of what to do with women. Communitas is an intense engagement with central figures in the history of political thought – Augustine, Hobbes, Rousseau – but also a remarkably efficient avoidance of women (...) and difference. Even as he deals with Augustine, who cannot stop discussing begetting and desire, and Hobbes, who insists on the maternal right of nature, Esposito's attention remains fixed on the fraternal violence rather than parental sex as the founding of community, and the result is a strangely phallic work.

Various claims have been made concerning the role of narrative in grief. In this paper, we emphasize the need for a discerning approach, which acknowledges that narratives of different kinds relate to grief in different ways. We focus specifically on the positive contributions that narrative can make to sustaining, restoring and revising a sense of who one is. We argue that, although it is right to suggest that narratives provide structure and coherence, they also play a complementary role in disrupting (...) established structure and opening up new possibilities. We add that both of these roles point to the importance of interpersonal, social and cultural factors in shaping the trajectory of grief. We conclude by briefly considering the implications for distinguishing between typical and pathological forms of grief. (shrink)

Husserl’s early picture of explanation in the sciences has never been completely provided. This lack represents an oversight, which we here redress. In contrast to currently accepted interpretations, we demonstrate that Husserl does not adhere to the much maligned deductive-nomological (DN) model of scientific explanation. Instead, via a close reading of early Husserlian texts, we reveal that he presents a unificationist account of scientific explanation. By doing so, we disclose that Husserl’s philosophy of scientific explanation is no mere anachronism. It (...) is, instead, tenable and relevant. We discuss how Husserl and other contemporary thinkers draw theoretical inspiration from the same source—namely, Bernard Bolzano. Husserl’s theory of scientific explanation shares a common language and discusses the same themes as, for example, Phillip Kitcher and Kit Fine. To advance our novel reading, we discuss Husserl’s investigations of grounding, inter-lawful explanation, intra-mathematical explanation, and scientific unification. (shrink)

Objectives To review the extant literature on HIV criminal laws, and to determine the impact of these laws on public health practice.Methods The available research on this topic was obtained and reviewed.Results The extant literature addressed three main topics: people's awareness of HIV criminal laws; people's perceptions of HIV criminal laws; and the potential effects of HIV criminal laws on people's sexual, HIV-status disclosure and healthcare-seeking practices. Within these categories, the literature demonstrated a high level of awareness of HIV criminal (...) laws, but a poor comprehension of these laws. For perceptions, on the whole, the quantitative research identified support for, while the qualitative literature indicated opposition to, these laws. Lastly, the behavioural effects of HIV criminal laws appear to be complex and non-linear.Conclusions A review of the extant literature from a public health perspective leads to the conclusion that HIV criminal laws undermine public health.

We report two new phenomena of deontic reasoning: (1) For conditionals with deontic content such as, "If the nurse cleaned up the blood then she must have worn rubber gloves", reasoners make more modus tollens inferences (from "she did not wear rubber gloves" to "she did not clean up the blood") compared to conditionals with epistemic content. (2) For conditionals in the subjunctive mood with deontic content, such as, "If the nurse had cleaned up the blood then she must have (...) had to wear rubber gloves", reasoners make the same frequency of all inferences as they do for conditionals in the indicative mood with deontic content. In this regard, subjunctive deontics are different from subjunctive epistemic conditionals: reasoners interpret subjunctive epistemic conditionals as counterfactual and they make more negative inferences such as modus tollens from them. The experiments show these two phenomena occur for deontic conditionals that contain the modal auxiliary "must" and ones that do not. We discuss the results in terms of the mental representations of deontic conditionals and of counterfactual conditionals. (shrink)

Recently, patient safety has gained popularity in the nursing literature. While this topic is used extensively and has been analyzed thoroughly, some of the concepts upon which it relies, such as risk, have remained undertheorized. In fact, despite its considerable use, the term ‘risk’ has been largely assumed to be inherently neutral — meaning that its definition and discovery is seen as objective and impartial, and that risk avoidance is natural and logical. Such an oversight in evaluation requires that the (...) concept of risk be thoroughly analyzed as it relates to nursing practices, particularly in relation to those practices surrounding bio‐political nursing care, such as public health, as well as other more trendy nursing topics, such as patient safety. Thus, this paper applies the Evolutionary Model of concept analysis to explore ‘risk’, and expose it as one mechanism of maintaining prescribed/ proscribed social practices. Thereby, an analysis of risk results in the definitions and roles of the discipline and profession of nursing expanding from solely being dedicated to patient care, to include, in addition, its functions as a governmental body that unwittingly maintains hegemonic infrastructures.

The authors outline a theory of conditionals of the form If A then C and If A then possibly C. The 2 sorts of conditional have separate core meanings that refer to sets of possibilities. Knowledge, pragmatics, and semantics can modulate these meanings. Modulation can add information about temporal and other relations between antecedent and consequent. It can also prevent the construction of possibilities to yield 10 distinct sets of possibilities to which conditionals can refer. The mental representation of a (...) conditional normally makes explicit only the possibilities in which its antecedent is true, yielding other possibilities implicitly. Reasoners tend to focus on the explicit possibilities. The theory predicts the major phenomena of understanding and reasoning with conditionals. (shrink)

Recently, focus groups and qualitative interviews with nurses who provide frontline care for persons living with HIV highlighted the contentiousness surrounding the seemingly innocuous activity of counselling clients about HIV‐status disclosure, hereafter disclosure counselling. These empirical studies highlighted that while some nurses felt they should instruct clients to disclose their HIV‐positive status if HIV transmission were possible, other nurses were equally adamant that such counselling was outside the nursing scope of practice. A review of these opposing perceptions about disclosure counselling, (...) including an examination of the empirical evidence which supports each point, revealed that the dichotomous arguments needed to be nuanced. The empirical evidence about serostatus disclosure neither supported nor refuted either of these assertions; rather, it substantiated parts of each. To create this understanding, both empirical and theoretical works are used. First, the results of empirical studies about serostatus disclosure, or lack thereof and HIV transmission is presented; as part of this, Marks and Crepaz's HIV disclosure and exposure framework is examined. Second, the work of Michel Foucault on disciplinary and pastoral power is drawn from. The outcome is a nuanced understanding about the interrelationships between disclosure counselling and nursing practice and a final interpretation about what this understanding means for public health practice.

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)

This study tests an instructional model designed to empower students in an early childhood classroom as emerging digital storytellers. Educators can use digital storytelling to support students’ learning by encouraging them to organize and express their ideas and knowledge in an individual and meaningful way while developing voice and facility in child-computer interactions. This work also helps develop traditional communication skills, fosters collaboration, and strengthens emergent literacy practices. Students may develop enhanced communications skills by learning to organize their ideas, ask (...) questions, express opinions, and construct narratives as they interact with others and computers in the creation of digital stories. The “Emerging Digital Storytellers” instructional model focuses on social-emotional development and finding student voice through writing and digital content construction in the early childhood educational context.

Four studies show that observers and readers imagine different alternatives to reality. When participants read a story about a protagonist who chose the more difficult of two tasks and failed, their counterfactual thoughts focused on the easier, unchosen task. But when they observed the performance of an individual who chose and failed the more difficult task, participants' counterfactual thoughts focused on alternative ways to solve the chosen task, as did the thoughts of individuals who acted out the event. We conclude (...) that these role effects may occur because participants' attention is engaged when they experience or observe an event more than when they read about it. (shrink)

O’BYRNE P and WATTS J. Nursing Inquiry 2012 [Epub ahead of print] Include, differentiate and manage: gay male youth, stigma and healthcare utilizationIn Canada, there has been a recent increase in HIV incidence among young men who have sex with men. However, gay male youth (GMY) may forego HIV testing due to fear of stigmatization. Therefore, the aim of this research was to explore the perceptions of stigma in health care within this population. The research was conducted through a (...) series of semi‐structured interviews with eight GMY aged 20–29, who frequented a gay‐friendly clinic in downtown Ottawa, Canada. In a sub‐analysis of the interviews utilizing the work of Hardt and Negri’s three‐part sequence – inclusion, differentiation and management – we found that homosexuality‐related stigmatization affects the interaction between GMY and health professionals. Interview participants perceived HIV‐related risk counselling as a manifestation of stigma. These findings reveal that the experience of stigma and stigmatization is not necessarily based on health professionals’ intentions, but rather, on patients’ perceptions of the interactions they have with health professionals. Specific modifications to the delivery of health care may help to overcome stigmatization. (shrink)

Of all the terms Jean Améry might have chosen to explain the deepest effects of torture, the one he selected was world. To be tortured was to lose trust in the world, to become incapable of feeling at home in the world. In July 1943, Améry was arrested by the Gestapo in Belgium and tortured by the SS at the former fortress of Breendonk. With the first blow from the torturers, he famously wrote, one loses trust in the world. With (...) that blow, one can no l onger be certain that “by reason of written or unwritten social contracts the other person will spare me — and more precisely stated, that he will respect my physical, and with it also my metaphysical, being.” In a vault inside the fortress, beyond the reach of anyone who might help — a wife, a mother, a brother, a friend — it turned out that all social contracts had been broken and torture was possible. His attackers had no respect for him, and no-one else could or would help. (shrink)

When people understand a counterfactual such as “if the flowers had been roses, the trees would have been orange trees,” they think about the conjecture, “there were roses and orange trees,” and they also think about its opposite, the presupposed facts. We test whether people think about the opposite by representing alternates, for example, “poppies and apple trees,” or whether models can contain symbols, for example, “no roses and no orange trees.” We report the discovery of an inference‐to‐alternates effect—a tendency (...) to make an affirmative inference that refers to an alternate even from a negative minor premise, for example, “there were no orange trees, therefore there were poppies.” Nine experiments show the inference‐to‐alternates effect occurs in a binary context, but not a multiple context, and for direct and indirect reference; it can be induced and reduced by prior experience with similar inferences, and it also occurs for indicative conditionals. The results have implications for theories of counterfactual conditionals, and of negation. (shrink)

This study continues such explorations by examining (i) (...) why one self‐defined gay man engaged in unsafe sex, and (ii) how he defined unsafe sex. The findings suggest that, for this man, his sexuality is nomadic and that what he feels is unsafe sex is the outcome of his nomadic sexuality conflicting with social imperatives for sexual stratification.

This paper examines Angela Davis’s 1969 Lectures on Liberation and her critique of Jean-Paul Sartre’s views regarding freedom and enslaved agency. Across four sections, the paper etches out Davis’s response to what she calls Sartre’s ‘notorious statement’ through her own existential reading of Frederick Douglass’s resistance to chattel slavery. Instead of interpreting Davis’s existential insights through the work of Sartre or other Western continental philosophers, the paper engages Lewis Gordon, George Yancy, Frank Kirkland, and LaRose Parris to develop an alternative (...) frame for assessing Davis’s existential thinking. Embracing a diverse lineage of existential philosophy, the paper argues for Black-centered approaches to existential philosophy that resonate with, but are not reducible or indebted to, European existentialism.

In this interview with Kathryn Sophia Belle (formerly Kathryn T. Gines), Edward O'Byrn discusses Belle's publications from 2010–2017. His questions focus on Simone de Beauvoir and her use of analogy in The Second Sex, along with broader questions that engage Belle's work on existential philosophy, Beauvoir, Black feminism, and intersectionality.

Lewis Gordon's Fear of Black Consciousness is a resolute response to the ongoing pessimism present in contemporary culture and academia regarding Black life. As a towering figure in Black existential philosophy, Gordon seamlessly weaves together discussions of contemporary and historical Western philosophers such as Gabriel Marcel and Friedrich Nietzsche with his analyses of film, music, culture, and more. Across the text's twelve chapters, Gordon reveals the pervasiveness of anti-black ideologies while challenging his readers to affirm various forms of resistance to (...) violence, invisibility, and erasure. The book is written for an audience beyond academia, and is invested in telling a practical philosophical story about generating an empowering sense of Black consciousness. Sprinkled with personal stories, witty anecdotes, and powerful arguments, the book encourages readers to rethink historical descriptions of anti-black violence as well as the vocabulary used to talk about race and racism today. An example of this is Gordon's discussion of various slave trades across the planet. He writes, ‘Only the Arab designation is correct, since it refers to Arabs trading in the enslavement of peoples. The others should properly be called the European slave trade and the East Indian slave trade or Asian slave trade. Oceans do not trade people’ (pp. 52). Another insightful aspect of the text is the author's study of films like Jordan Peele's Get Out, Boots Riley's Sorry to Bother You, and Ryan Coogler's Black Panther. Through these films, he provides a detailed look at how cinematic representation engages complex dialogues of anti-Blackness and Black power, as well as anti-capitalism. Overall, Gordon's book is a wonderful resource for anyone curious about cultivating a resistant and critical lens on contemporary culture. The aim of this review is to highlight a few of the book's major contributions for academics, casual readers, and those interested in ongoing discussions within Africana philosophy. (shrink)
