As with other fields of applied ethics, philosophers engaged in business ethics struggle to carry out substantive philosophical reflection in a way that mirrors the practical reasoning that goes on within business management itself. One manifestation of the philosopher’s struggle is the field’s division into approaches that emphasize moral philosophy and those grounded in the methods of social science. I claim here that the task for those who come to business ethics with philosophical training is to avoid unintentionally widening the (...) gap between philosophical theory and business management by emphasizing the centrality of practical wisdom to both good managment and to the moral life. Distinguishing my own approach from recent emphases on phronesis in management literature, I draw on the concepts of social practice and of narrative to tie practical reasoning to a company’s unique story. Practical reason, social practices and narrative are employed together to give an account of the art of management at Patagonia. The essay hopes to both provide a way for philosophers engaged with business ethics to see family resemblances between their practices and those of business management and to offer a pedagogical example useful for those in any discipline interested in viewing businesses ethically.

Ethical, Legal and Social Aspects (ELSA) originated in the 4thEuropean Research Framework Programme (1994) andresponsible research and innovation (RRI) from the EC researchagenda in 2010. ELSA has received renewed attention inEuropean funding schemes and research. This raises the questionof how these two approaches to social responsibility relate toone another and if there is the possibility to align. There is aneed to evaluate the relationship/overlap between ELSA and RRIbecause there is a possibility that new ELSA research will reinventthe wheel if it (...) does not engage with the body of literaturealready present in RRI research. This provides unneeded extrabureaucracy, reformulations of research agendas, extrainvestment, and an overabundance of frameworks to implement,and ELSA research does not take advantage of the body ofresearch developed in RRI. This paper evaluates how ELSA andRRI diverge, are complementary, and can be aligned. (shrink)

Motivating this article is an interest in how postphenomenological technical relations participate in aesthetic experiences. Introducing aesthetic experience into our analyses of technical relations allows us to better tease apart the distinction between our relationship with the artefact, and how we experience that relationship. However, the sublime poses a unique set of complications for postphenomenologists. Thanks to the overwhelming qualities of the sublime, it is unclear where sublimity fits within the Ihdean relational taxonomy—or indeed, if it can at all, given (...) that sublime experience would in principle overwhelm and dissolve the extant relation. This article resolves this apparent tension, and offers an accounts of how sublime experience is able to be reconciled with Ihdean postphenomenology. (shrink)

In this article, I describe a novel position on the semantics of artificial intelligence. I present a problem for the current artificial neural networks used in machine learning, specifically with relation to natural language tasks. I then propose that from a metasemantic level, meaning in machines can best be interpreted as radically contextualist. Finally, I consider what this might mean for human‐level semantic competence from a comparative perspective.

The neurodiversity view makes both a conceptual and a political claim. Conceptually, the neurodiversity view holds that certain neurocognitive differences currently classified as disorders—autism, most notably—are best understood as forms of diversity. Politically, it holds that, rather than being medicalized and ‘treated’, neurodiversity ought to be respected in the way other human differences—such as differences in race and sexual orientation—are respected. In this article, I challenge the arguments given in support of neurodiversity’s conceptual claim, while defending its political aims of (...) respect, inclusion, and accommodation. Although neurodiversity provides a compelling challenge to the status quo, I conclude that its most prominent arguments fall short of establishing that autism is not a disorder. As I go on to argue, however, the fact that autism is a disorder does not entail that medicalization is the only course. My view is ultimately that social change and medical intervention need not be considered mutually exclusive. (shrink)

Linguistics as a science has rapidly changed during the course of a relatively short period. The mathematical foundations of the science, however, present a different story below the surface. In this paper, I argue that due to the former, the seismic shifts in theory over the past 80 years opens linguistics up to the problem of pessimistic meta-induction or radical theory change. I further argue that, due to the latter, one current solution to this problem in the philosophy of science, (...) namely structural realism :403–424, 1998; French in Proc Aristot Soc 106:167–185, 2006), should be viewed as especially enticing for linguists, as their field is a largely structural enterprise. I discuss particular historical instances of theory change in generative syntax before investigating two views on the nature of structural properties and eventually proposing an approach in terms of invariance :162–186, 2015) as a grounding for structural realism in the history and philosophy of linguistics.

The use of opaque, uninterpretable artificial intelligence systems in health care can be medically beneficial, but it is often viewed as potentially morally problematic on account of this opacity—because the systems are black boxes. Alex John London has recently argued that opacity is not generally problematic, given that many standard therapies are explanatorily opaque and that we can rely on statistical validation of the systems in deciding whether to implement them. But is statistical validation sufficient to justify implementation of these (...) AI systems in health care, or is it merely one of the necessary criteria? I argue that accountability, which holds an important role in preserving the patient‐physician trust that allows the institution of medicine to function, contributes further to an account of AI system justification. Hence, I endorse the vanishing accountability principle: accountability in medicine, in addition to statistical validation, must be preserved. AI systems that introduce problematic gaps in accountability should not be implemented. (shrink)

What does it mean to be “strengths-based” or to be a “strengths-based practitioner?” These are diffuse areas that are generic and ill-defined. Part of the confusion arises from the customary default of practitioners and leaders across many cultures to label anything positive or complimentary as “strengths-based,” whether that be an approach, a theoretical orientation, an intervention, or a company. Additional muddle is created by many researchers and practitioners not making distinctions between very different categories of “strength” in human beings – (...) strengths of character, of talent/ability, of interest/passion, of skill/competency, to name a few. To add clarity and unification across professions, we offer seven characteristics and a comprehensive definition for a character strengths-based practitioner. We center on the type of strength referred to as character strengths and explore six guiding principles for understanding character strengths (e.g., character is plural; character is being and doing) and their practical corollaries. Reflecting this foundation and based on character strengths research, our longstanding work with strengths, discussions with practitioners across the globe, and a practitioner survey asking about strength practices (N= 113), we point out several character strengths practices or approaches we describe as soaring (e.g., explore and encourage signature strengths; practice strengths-spotting), emerging (e.g., the integration of mindfulness and character strengths), or ripe with potential (e.g., phasic strengths; the tempering effect; the towing effect). We use the same framework for describing general research domains. Some areas of research in character strengths are soaring with more than 25 studies (e.g., workplace/organizations), some are emerging with a handful of studies (e.g., health/medicine), and others are ripe with potential that have none or few studies yet opportunity looms large for integrating character science (e.g., peace/conflict studies). Using this framework, we seek to advance the exchange and collaboration between researcher and practitioner, as well as to advance the science and practice of character strengths. (shrink)

The Trump Administration's governance of COVID-19 racial health disparities data has become a key front in the viral war against the pandemic and racial health injustice. In this paper, I analyze how the COVID-19 pandemic joins an already ongoing racial spectacle and system of structural gaslighting organized around “racial health disparities” in the United States and globally. The field of racial health disparities has yet to question the domain assumptions that uphold its field of investigation; as a result, the entire (...) reform program called for by racial health disparities science is already featured on the menu of the white supremacist power structure. The societal infrastructure that produces scientific knowledge about patterns of health and disease in the human population needs to confront its structural position as part of the racial spectacle organized around racial health disparities in the United States. This paper offers an interpretation of racial antimatter to explain why the data will not save us in the COVID-19 pandemic, drawing on articulations of racial spectacle and structural gaslighting within critical race theory and Afropessimist thought. By positioning events in the COVID-19 pandemic together within the same racially speculative frame, I show how the collection of racial health disparities data came up against white supremacists’ political ambitions in a time-space where the demand for human life to matter and the iterative regeneration of racial antimatter collided. This paper highlights the need for ongoing analysis of the unfolding and future spectacles organized around racial health disparities. (shrink)

Experimental tests about cross-cultural differentiation of cognitive style conclude that East Asian and Western cognition differ. Tendencies described as East Asian include holism, non-linearity, expectation of change, relationalism, field dependence, causal pluralism, dialecticism, and a tolerance of contradiction. Cross-cultural psychologists generally refrain from discussing the intellectual history or cultural evolution of these differences, preferring to explain results on cognitive scales in terms of results on social scales assessed using present-day participants. The present article attempts to partially close this explanatory gap (...) through detailed discussion of tendencies of East Asian cognitive style as represented in what is probably the most influential book in the history of East Asia, The Book of Changes. This study purports to show that the content of the Yijing 易經 and its commentaries is best described in terms of the cognitive tendencies just mentioned, that reading the Yijing activated those cognitive tendencies, and that the Yijing attained prodigious influence on subsequent Chinese and East Asian cultures through four known mechanisms of cultural transmission. Informed by this case study, researchers of cross-cultural cognition may be positioned to develop a richer appreciation of the cultural representation and evolution of East Asian cognitive style in historical context.

I motivate and develop a use-based semantic theory in opposition to the dominant paradigm in philosophical and linguistic semantics. Drawing inspiration from Wilfrid Sellars, I argue that contemporary semantic theories are faced with a basic problem of explanatory circularity. These theories universally presuppose that worldly knowledge of such things as properties or sets of possible worlds precedes and underlies knowledge of meaning. However, I argue that it is only through learning a language--mastering the rules governing the use of the expressions (...) belonging to that language--that speakers can possibly have knowledge of the worldly entities appealed to by semanticists at the base level of their semantic theories. In response to this fundamental problem, I develop a formal semantic framework in which the meaning of a sentence is understood directly in terms of its role in discourse. In contrast to existing semantic frameworks, this framework does not presuppose speakers' worldly knowledge, and so is actually able to explain it. The result is not just a new kind of semantic theory, but a new conception of the relation between meaning and the world. (shrink)

War is a highly gendered experience which is both informed by and informs constructions of masculinity and femininity. The dominant depiction of masculine heroes and feminine victims simplifies the complex intersections of militarism, nationalism and gendered roles and identities. Focusing on a case study of the Anglo-Irish War or War of Independence (1919–1921), this paper examines how violence against women, especially sexual violence, was written about and reported in ways which framed representations of Irish and British masculinity and Irish femininity. (...) In addition, by analysing a range of varied sources including newspapers, autobiographical accounts and recorded testimonies, this paper attempts to assess the extent to which violence against women formed a key aspect of military practice in the war. In conclusion, I engage with some of the difficulties faced by researchers today in exploring evidence of gendered violence in specific historical, cultural and militarized contexts. (shrink)

When you are indifferent between two options, it’s rationally permissible to take either. One way to decide between two such options is to flip a fair coin, taking one option if it lands heads and the other if it lands tails. Is it rationally permissible to employ such a tie-breaking procedure? Intuitively, yes. However, if you are genuinely risk-averse—in particular, if you adhere to risk-weighted expected utility theory (Buchak in Risk and rationality, Oxford University Press, 2013) and have a strictly (...) convex risk-function—the answer will often be no: the REU of deciding by coin-flip will be lower than the REU of choosing one of the options outright (so long as at least one of the options is a nondegenerate gamble). This turns out to be a significant worry for risk-weighted expected utility theory. I argue that it adds real bite to established worries about diachronic consistency afflicting views, like risk-weighted expected utility theory, that violate Independence. And that, while these worries might be surmountable, surmounting them comes at a price. (shrink)

From a pragmatic standpoint, there is great utility in proffering a theoretical "third way" to a traditionally binary problem, even if that third way is no more complicated than harnessing the strengths of two competing positions, and mitigating their weaknesses in an attempt to resolve the issue at hand. In continental philosophy, Ricour gained notoriety by utilizing such an approach in his treatment of the Gadamer and Habermas debates; Susan Haack achieved similar renown in her attempt to bridge the divide (...) between foundationalist and coherentist theories of epistemic belief justification by providing a viable point of entry into coherent matrices of belief through an originary, experiential foundations. While foundherentism may not have achieved the level of success Haack might have hoped for, it has, whether she could have envisaged it or not, practical value outside of epistemology, particularly as an ontological framework. This essay explores how foundherentism is more apt as a means of understanding the human capacity for world-formation as described by Heidegger. By explicating the foundherentist perspective as an ontological structure, and placing it into dialogue with prominent conceptualizations of "world," a greater understanding of how ‘worlds-as-such’ are constructed can be brought into focus.

Are mandatory lockdown measures, which place restrictions on one’s freedom to move and assemble, justifiable? Offhand, such measures appear to compromise important rights to secure goals of public health. Proponents of such measures think the trade-off is worth it; opponents think it isn’t. However, one might think that casting the debate in these terms concedes too much to the opponents. Mandatory lockdown measures don’t infringe important rights because no one has a right to impose a risk of grievous harm on (...) others—and, in the context of a pandemic, participating in the prohibited activities (e.g., going out to the bar) does just that. -/- This chapter explores whether this defense of mandatory lockdown measures holds up. It, first, considers whether we have a right against risk imposition—and, if so, how such a right is best understood. It then considers the objection that, even if there is such a right, people who voluntarily choose to engage in the prohibited activities—at least if fully appraised of the risks involved—effectively waive it. The chapter argues that this objection fails. (shrink)

Through a reinterpretation of publications, interviews with long-term activists, and an analysis of change in the social environment, this article explains why feminist ideology failed to create unity among feminist women in the United States during the period 1966-1975, the years when contemporary feminism emerged. In spite of the desire to create a community of women to challenge the existing sociocultural structure, schisms within the movement often created divisive and antagonistic feminist group relations. In contrast to earlier research that attributed (...) this lack of unity to competing ideologies, this article argues that, in many cases, feminist leaders used ideology and theory to promote radical self-identities that maintained existing social structural divisions. Thus, while feminism established a principle of unity for women as a group, disputes over ideological purity created divisions within the movement based on differences among women. (shrink)

The Metaphysical Club, a gathering of intellectuals in the 1870s associated with Harvard, is widely recognized as the crucible where pragmatism, America's distinctively original philosophy, was refined and proclaimed. Louis Menand's bestseller about the group was a dramatic publishing success. However, only three actual members - Oliver Wendell Holmes Jr., Charles S. Peirce, and William James - appear in this book, alongside other thinkers such as John Dewey who were never in the Club. The Real Metaphysical Club tells the full (...) story of how this influential group shifted the course of philosophy in America. In addition to pioneering pragmatism, the group explored radical empiricism and idealism, and formulated personalism and process philosophy, equally important developments. This volume contains thirty-seven important writings dating from 1870 to 1885 by the real members of the Metaphysical Club. The first section centers on pragmatism and science; the second part collects writings of the lawyers; and the third part covers idealist and personalist philosophers. Many of these writings have never been reprinted before, and nothing like this impressive collection has ever been attempted. A general introduction provides a narrative history, and the editors' three introductions to the volume's sections vividly bring to life the intense meetings, sustained debates, and pioneering thought from the Metaphysical Club.

This paper identifies experiential processes through which social structures become taken for granted, termed processes of “structure marginalization”. Passive processes of structure marginalization relegate social structures to the margin of experience without the use of higher-order cognitive acts such as evaluation and reflection. Examples include adapting to social structures via routine and habitual practices, a lack of conscious awareness of the complexity, historical formation, and other details of social structures, and rendering social structures irrelevant when they are unreflectively judged to (...) be of no value for achieving ends. Active processes of structure marginalization reflectively and discursively relegate social structures to marginal consciousness. Examples include the use of naturalistic and necessitarian explanations for the social order that implicitly justify it as inalterable or “just the way things are”, normative justifications for the status quo, and conscious awareness of one’s powerlessness to control social-structural conditions. Active processes of structure marginalization originate in passive processes. The goal of the typology is to explain, at the level of experience, why social structures typically remain unproblematic and unnoticed in everyday life, even during periods of social crisis and change or when existing structures produce harmful effects.

Liberal states traditionally rely on a reasonably narrow set of tools for engaging in social regulation. All of these tools are meant to change individual behaviors. Laws come with implicit force, financial regulations come with monetary carrots and sticks, and information provision informs people of the things that policymakers think they should know. Each of these is meant to guide individual choice making by changing how people evaluate their available options. Because this set of tools is meant to change individual (...) behaviors, it is worth considering what implicit assumptions this set of tools makes about the individuals whose behaviors policymakers are looking to change. Behavioral and social science has not only found some limitations on existing policy tools but has also pointed in the direction of some new tools as well. This is because the model of human choice and behavior is now richer. Nudges and norms provide an expanded toolset for policymakers but raise interesting questions about the legitimacy of the state taking advantage of reductions in agency to achieve policy ends. I argue that this framing misconstrues the situation and suggest that the appropriate guide to any options in the policy tool kit is one of nurturing rather than inhibiting citizen autonomy. Sometimes, this will recommend the use of norms or nudges in place of the standard policy tools. (shrink)

In this paper we consider a puzzle concerning Hume's account of time and what he calls “steadfast unchanging objects”—that is, unchanging objects coexisting with temporal successions. On the one hand, Hume maintains that steadfast unchanging objects are temporally indivisible. On the other, he allows that such unchanging objects are capable of undergoing a determinate number of alterations in a given length of time, which seems to imply that they are at least potentially temporally divisible. After arguing that Donald Baxter's influential (...) interpretation of Hume's theory of time cannot resolve this tension, we propose that Hume offers a skeptical resolution of the difficulty.

When we raise children what we are typically aiming for is a kind of flourishing; we want childrento live well as children, and to grow to become adults who live well too. Undoubtedly, part of what we are aiming forwhen we aim for a child’s flourishing is that they meet their developmental milestones well, and that they succeedamong their peers. We are also generally interested in how a child regards themselves; we want children tobelieve that they have value, and that (...) what they care about has value too. We also typically want children to havean appreciation for their relative value among others; that they are important among many other important beings,and we want them to act well in that knowledge. Of course, not all persons who raise children aim for those ends.Some do not care for how a child conceives of themselves, or whether the child flourishes at all. Others care fortheir children, and how they conceive of themselves, but aim poorly. As result, some children come to believe thatthey only deserve love and kindness when they succeed at meeting a caregiver’s ends. Some children come tobelieve that they have no worth at all. And yet other children, rather than believing they are unworthy, come toregard themselves as of superior worth; as children, for example, who bully and sneer at other children for being adifferent race, a different class, gender, ability, etc. may. When a child comes to understand themselves in theseterms, we typically see it at best as morally problematic, and at worst as a tragedy. Despite our interest inchildren’s self-conceptions, and the vast literature on how to conceive of and regard children, there is relatively littleregarding how children should conceive of and regard themselves. In order to explain how children shouldconceive of themselves it is my contention that a new account of self-respect is needed for the context of childhood;one that is responsive to the moral value of children, as well as their developmental capacities to recognize thatvalue. Given that developmental psychology is complex and subject to significant variation as children develop, myaim in this paper is to offer a snapshot of what I take self-respect to amount to in early childhood. In particular, Ifocus on an account fitting for children between three to six years of age. (shrink)

Have you ever wondered what God’s inner emotional life might be like? Within Christian thought, there are conflicting answers to this question. The majority of Christian theologians throughout history have said that God cannot be moved by creatures to feel anything. God does not literally have empathy, mercy, or compassion. Instead, God only feels pure undisturbed happiness. This view is called divine impassibility. In the 20 th Century, Christian theologians by and large came to reject this understanding of God in (...) favour of divine passibility which affirms that God can be moved by creatures, and God can literally have empathy, mercy, and compassion. Yet the 21 st Century has seen a renewed interest in this more historical understanding of God. How Christianity came to have two radically different portrayals of God is a puzzle, to be sure, but that is not one that I shall try to address here. Instead, my interest is in unpacking these two different conceptions of God, and briefly offering reasons for affirming divine passibility. The reasons that I discuss centre around a central theme within Christian thought—the goal of entering into a close, personal relationship with God. I start by defining some key terms, and then proceed to offer two arguments in favour of divine passibility. The first is the problem of knowing God well, and the second is based on the human desire for empathy. (shrink)

Central to the social membership model of animal rights is the claim that relations with nonhuman animals should be reorganized such that domesticated animals are recognized as members of our shared societies. Though some elements of the membership model remain contested, the core of the membership model is that domesticated animals have a claim on, and a direct entitlement to, the benefits of cooperative relations. For many political theorists, however, distributive justice considerations apply only to a certain kind of cooperative (...) relationship. The community of justice recipients is thought to be limited by what Brian Berkey calls the Contribution/Capacity Basis of Entitlement. Accordingly, justice considerations apply to a scheme of cooperation and a conception of justice “entail[s] direct entitlements only for those who are contributors, or, alternatively, those who at least possess the capacities that are necessary to be capable of contributing to such a scheme”. This thesis – referred to as ‘contributionism’ – has typically been utilized to exclude nonhuman animals from justice considerations. The paper argues that contributionism is not fundamentally at odds with justice for domesticated animals, and conversely that contributionism remains a useful conceptual tool for explaining resource sharing with these nonhuman animals.

How should you evaluate your choices when you’re unsure what their outcomes will be? One popular answer is to rank your options in terms of their expected utilities. But what should you do when you think that the value of their respective outcomes might be incommensurable? In the face of incommensurable values, it no longer makes sense to speak of ranking your options according to expected utility. Are there any general principles to guide us when facing decisions of this kind? (...) If only! This chapter develops an impossibility result: it holds that there are a handful of independently plausible constraints that no such decision theory can jointly satisfy. The result, while depressing, can be used to helpfully classify extant approaches based on which of the constraints they violate. (shrink)

Scholars have focused on algorithms used during sentencing, bail, and parole, but little work explores what we term “carceral algorithms” that are used during incarceration. This paper is focused on the Pennsylvania Additive Classification Tool used to classify prisoners’ custody levels while they are incarcerated. Algorithms that are used during incarceration warrant deeper attention by scholars because they have the power to enact the lived reality of the prisoner. The algorithm in this case determines the likelihood a person would endure (...) additional disciplinary actions, can complete required programming, and gain experiences that, among other things, are distilled into variables feeding into the parole algorithm. Given such power, examining algorithms used on people currently incarcerated offers a unique analytic view to think about the dialectic relationship between data and algorithms. Our examination of the PACT is two-fold and complementary. First, our qualitative overview of the historical context surrounding PACT reveals that it is designed to prioritize incapacitation and control over rehabilitation. While it closely informs prisoner rehabilitation plans and parole considerations, it is rooted in population management for prison securitization. Second, on analyzing data for 146,793 incarcerated people in PA, along with associated metadata related to the PACT, we find it is replete with racial bias as well as errors, omissions, and inaccuracies. Our findings to date further caution against data-driven criminal justice reforms that rely on pre-existing data infrastructures and expansive, uncritical, data-collection routines. (shrink)

In their recent book, Ladyman and Wiesner (What is a complex system?, Yale University Press, 2020) delineate the bounds of the exciting interdisciplinary field of complexity science. In this work, they provide examples of generally accepted complex systems and common features which these possess to varying degrees. In this paper, I plan to extend their list to include the formal study of natural language, i.e. linguistics. In fact, I will argue that language exhibits many of the hallmarks of a complex (...) system, specifically a complex biological system. Thus, my aim is to advocate contra the the ‘Minimalist Program’ (Chomsky, The minimalist program, MIT Press, Cambridge, 1995), which motivates simple underlying mechanisms (i.e. Merge) in their idealisations, that biolinguistics should embrace a ‘Maximalist Program’ in which multiple subfields contribute component explanations to an emerging whole.

Perceived size is a function of viewing distance, retinal images size, and various contextual cues such as linear perspective and the size and location of neighboring objects. Recently, we demonstrated that illusion magnitudes of classic visual size illusions may be greatly enhanced or reduced by adding dynamic elements. Specifically, a dynamic version of the Ebbinghaus illusion (classically considered a “size contrast” illusion) led to a greatly enhanced illusory effect, whereas a dynamic version of the Corridor illusion (a “size constancy” illusion) (...) led to a greatly diminished illusory effect. Although these differences may arise from the different processes underlying these illusions (size contrast vs. size constancy), the dynamic variants we tested in our previous work also differed in the nature of the dynamic elements; specifically, whereas the Dynamic Ebbinghaus included a moving target and inducers that changed size and position, the Dynamic Corridor only included a moving target on a static background. Here, we explore further dynamic versions of the Ebbinghaus illusion and the Corridor and Ponzo illusions by separately manipulating three types of dynamic elements: target motion, context translation, and dynamic changes in context. Across five experiments examining 21 dynamic illusory configurations, adding target motion or a dynamically changing context separately resulted in little-to-no illusory effect. In contrast, the combination of target motion and a dynamically changing context led to a robust size illusion, consistent with an interactive effect. However, illusory effects that exceeded the matched classic, static illusory configuration were only observed for the dynamic versions of the Ebbinghaus illusion and the Revealed Ponzo illusions, in which the contextual elements changed size. We conclude that the combination of target motion and a dynamically changing context are necessary to produce dynamic size illusions, but that enhancement above and beyond static illusions may be largely specific to size contrast effects. Our results have important implications for the integration of motion signals, a ubiquitous environmental stimulus, in the perception of object size. (shrink)

Exploring long-term educational change, we investigate our re/construction of research methodology as we moved from a positivist framework to working with ideas drawn from Deleuze and Guattari. We reveal our becoming rhizomatic in data analysis in the metamodelling of the richness flowing horizontally through our practices. We tell of our struggles to escape hierarchical thinking and relations researching between the smooth and striated. A space of interactions, conversations and writings created relations between polyphonic voices, leading us to an emergent methodology. (...) Our struggle against hierarchies in data analysis yielded rich educational possibilities for becoming that Deleuzo-Guattarian thinking offers us. (shrink)

This book explores 'difficult conversations' in feminist theory as an integral part of social and theoretical transformations. Focussing on intersectionality within feminist theory, this book critically addresses questions of power and difference as a central feminist concern, rather than assuming that the needs and experiences of elite women apply to all women. It presents ethical, political, social, and emotional dilemmas while negotiating difficult conversations, particularly in terms of sexuality, class, 'race', ethnicity, and cross-identification between the researcher and researched. Topics covered (...) include challenging cultural relativism; queer marginalisation; research and affect; and feminism and the digital realm. This book is aimed primarily at students, lecturers and researchers interested in epistemology, research methodology, gender, identity, and social theory. The interdisciplinary nature of the book is aimed at reaching the broadest possible audience, including those engaged with feminist theory, anthropology, social policy, sociology, psychology, and geography.

This chapter defends the view that Arthur Schopenhauer and Siddhattha Gotama were unquestionably pessimistic philosophers, insofar as they converged in locating the source of life’s suffering within the person rather than the external world. However, in the process of outlining the significant continuities between their respective phenomenological analyses of life’s suffering, this chapter detects an important divergence between them. This stems from their contrasting metaphysical positions and ultimately impacts upon their respective interpretations of the significance of life’s suffering, as well (...) as their proposed solutions to it.
