This is a review of Julie Chajes, Recycled Lives: A History of Reincarnation in Blavatsky’s Theosophy, Oxford University Press, Oxford, 2019. The book, which falls under the broader umbrella of the academic study of Western esotericism, is concerned with the Russian occultist Helena Petrovna Blavatsky (1831–1891), her doctrine of reincarnation, its development through the different phases of her literary work, and her sources, whether these be Indian philosophy, Ancient Greek philosophy, or nineteenth-century science. Blavatsky’s project, which lies at (...) the crossroads of spiritualism and comparative philology, was to uncover what she believed was a primeval wisdom, parts of which, she thought, had been preserved in diffuse forms in the mythologies, religions, philosophies, and science of ancient civilizations (Hindus, Chaldeans, Egyptians, Greeks, Jews, etc.). According to Blavatsky, one of the fundamental elements of this primitive wisdom-religion is the belief in reincarnation. But—and this is the main focus of the book—it so happens, or so the author claims, that Blavatsky defended two different theories of reincarnation at different stages of her literary career; in Isis Unveiled (1877) she defended the theory of metempsychosis, whereas in The Secret Doctrine (1888) she defended a theory of reincarnation simpliciter. In this review, I briefly present each of these two theories from the author’s perspective before addressing the author’s take on the Ancient Greek and nineteenth-century sources of Blavatsky.

The continued development of General Circulation Models (GCMs) towards increasing resolution and complexity is a predominantly chosen strategy to advance climate science, resulting in channelling of research and funding to meet this aspiration. Yet many other modelling strategies have also been developed and can be used to understand past and present climates, to project future climates and ultimately to support decision-making. We argue that a plurality of climate modelling strategies and an equitable distribution of funding among them would be an (...) improvement on the current predominant strategy for informing policy making. To support our claim, we use a philosophy of science approach to compare increasing resolution and complexity of General Circulation Models with three alternate examples: the use of machine learning techniques, the physical climate storyline approach, and Earth System Models of Intermediate Complexity. We show that each of these strategies prioritises a particular set of methodological aims, among which are empirical agreement, realism, comprehensiveness, diversity of process representations, inclusion of the human dimension, reduction of computational expense, and intelligibility. Thus, each strategy may provide adequate information to support different specific kinds of research and decision questions. We conclude that, because climate decision-making consists of different kinds of questions, many modelling strategies are all potentially useful, and can be used in a complementary way. (shrink)

In this paper we assess the explanatory role of idealizations in ‘design explanations’, a type of functional explanation used in biology. In design explanations, idealizations highlight which factors make a difference to phenomena to be explained: hypothetical, idealized, organisms are invoked to make salient which traits of extant organisms make a difference to organismal fitness. This result negates the view that idealizations serve only pragmatic benefits, and complements the view that idealizations highlight factors that do not make a difference. This (...) analysis in particular strengthens the perspective that idealizations are means to highlight difference making factors, and identifies a novel, more direct role for idealizations in doing so. It thus offers a novel argument why in some explanatory contexts idealizations are in-eliminable. (shrink)

Within the political economy of informational capitalism, commercial surveillance practices are tools for resource extraction. That process requires an enabling legal construct, which this essay identifies and explores. Contemporary practices of personal information processing constitute a new type of public domain—a repository of raw materials that are there for the taking and that are framed as inputs to particular types of productive activity. As a legal construct, the biopolitical public domain shapes practices of appropriation and use of personal information in (...) two complementary and interrelated ways. First, it constitutes personal information as available and potentially valuable: as a pool of materials that may be freely appropriated as inputs to economic production. That framing supports the reorganization of sociotechnical activity in ways directed toward extraction and appropriation. Second, the biopolitical public domain constitutes the personal information harvested within networked information environments as raw. That framing creates the backdrop for culturally situated techniques of knowledge production and for the logic that designates those techniques as sites of legal privilege. (shrink)

It is difficult to consider, describe or address the ethical issues particular to qualitative research without experience and understanding of the technicalities of qualitative methodologies. The Australian National Statement on the Ethical Conduct of Research Involving Humans charges researchers with a responsibility to demonstrate that they have the appropriate experience, qualifications and competence for their proposed research. Ethical review committees have the responsibility to judge claimed research competence. This article provides practical guidance to researchers and review committees on using formal (...) qualifications and training, explicit claims of competence, and markers of in/competence to assess qualitative research competence.

When Locke mentions polygamy in his writings, he does not condemn the practice and, even seems to endorse it under certain conditions. This attitude is out of step with many of his contemporaries. Identifying the philosophical reasons that lead Locke to have this attitude about polygamy motivates our project. Because Locke never wrote a treatise on ethics, we look to number of different texts, but focus on An Essay Concerning Human Understanding and Essays on the Law of Nature, in order (...) to outline his basic ethical theory. We argue that this theory, the elements of which include moral mixed modes, the law of nature, and the comparison of these modes with this law, is broad enough to accommodate practices like polygamy. Our interpretation shows that Locke’s line of thought on marriage is strikingly flexible for the 17th century, and even compared to some contemporary public debates on marriage. (shrink)

Antoine Arnauld is well known as a passionate defender of Jansenism, specifically Jansen’s view on the relation between freedom and grace. Jansen and, early in his career Arnauld, advance compatibilist views of human freedom. The heart of their theories is that salvation depends on both the irresistible grace of God and the free acts of created things. Yet, in Arnauld’s mature writings, his position on freedom seems to undergo a significant shift. And, by 1689, his account of freedom no longer (...) seems Jansenist. In this paper, we offer an interpretation of Arnauld’s mature view on freedom, with a focus on his claim that freedom requires a “power to the opposite.” In order to see what he means by this, we look to several under-examined texts in his corpus for clues about how he understands the related topics of “infallible determination,” habit, and primo-primi motus. We argue that Arnauld’s mature view on freedom should be understood as libertarian. (shrink)

In light of new historical evidence regarding ethnomycologist R. Gordon Wasson’s correspondence with art historian Erwin Panofsky, this article provides an in-depth analysis of the presence of entheogenic mushroom images in Christian art within the context of the controversy between Wasson and philologist John Marco Allegro over the identification of a Garden of Eden fresco in the 12th century Chapel of Plaincourault in France. It reveals a compelling financial motive for Wasson’s refusal to acknowledge that this fresco represents Amanita muscaria, (...) as well as for Wasson’s reluctance to pursue his hypothesis regarding the entheogenic origins of religion into Christian art and artifacts. While Wasson’s view – that the presence of psychoactive mushrooms in the Near and Middle East ended around 1000 BCE – prevailed and stymied research on entheogens in Christianity for decades, a new generation of 21st century researchers has documented growing evidence of A. muscaria and psilocybin-containing mushrooms in Christian art, consistent with ethnobotanist Giorgio Samorini’s typology of mushroom trees. This article presents original photographs, taken during fieldwork at churches and cathedrals throughout Europe and the Middle East, that confirm the presence of entheogenic mushrooms in Christian art: in frescoes, illuminated manuscripts, mosaics, sculptures, and stained glass windows. Based on this iconic evidence, the article proposes a psychedelic gospels theory and addresses critiques of this theory by art historians, ardent advocates, medieval historians, and conservative Catholics. It calls for the establishment of an Interdisciplinary Committee on the Psychedelic Gospels to independently evaluate the growing body of evidence of entheogenic mushrooms in Christian art in order to resolve a controversial question regarding the possible role of entheogens in the history and origins of Christianity.

The olfactory system was traditionally thought to lack a thalamic relay to mediate top-down influences from memory and attention in other perceptual modalities. Olfactory perception was therefore often described as an outlier among perceptual modalities. It was argued as a result that olfaction was a canonical example of a direct perception. In this paper we review functional and anatomical evidence which demonstrates that olfaction depends on both direct pathway connecting anterior piriform cortex to orbitofrontal cortex and an indirect thalamic circuit (...) connecting posterior piriform cortex and orbitofrontal cortices to the olfactory system. We argue that the indirect corticothalamic circuit has the structure to potentially mediate mediates top-down influences of memory and attention in olfactory perception. This suggests that olfaction is not an outlier after all. (shrink)

The classic model of blood pressure regulation by Guyton et al. (Annu Rev Physiol 34:13–46, 1972a; Ann Biomed Eng 1:254–281, 1972b) set a new standard for quantitative exploration of physiological function and led to important new insights, some of which still remain the focus of debate, such as whether the kidney plays the primary role in the genesis of hypertension (Montani et al. in Exp Physiol 24:41–54, 2009a; Exp Physiol 94:382–388, 2009b; Osborn et al. in Exp Physiol 94:389–396, 2009a; Exp (...) Physiol 94:388–389, 2009b). Key to the success of this model was the fact that the authors made the computer code (in FORTRAN) freely available and eventually provided a convivial user interface for exploration of model behavior on early microcomputers (Montani et al. in Int J Bio-med Comput 24:41–54, 1989). Ikeda et al. (Ann Biomed Eng 7:135–166, 1979) developed an offshoot of the Guyton model targeting especially the regulation of body fluids and acid–base balance; their model provides extended renal and respiratory functions and would be a good basis for further extensions. In the interest of providing a simple, useable version of Ikeda et al.’s model and to facilitate further such extensions, we present a practical implementation of the model of Ikeda et al. (Ann Biomed Eng 7:135–166, 1979), using the ODE solver Berkeley Madonna. (shrink)

People struggle with religion and spirituality in several ways, including challenges in trusting God, confronting supernatural evil, tolerating other perspectives on religion, maintaining moral propriety, finding existential meaning, and managing religious doubt. These religious and spiritual struggles relate to both physical and mental health independently of other religious and distress factors. Causality in this connection needs further study, but evidence supports many potential causes and moderators of the link between R/S struggle and health. These include personality, social, and environmental influences, (...) including traumatic experiences and subcultural differences. Many theoretical questions remain unresolved, including how change in R/S struggle can predict or be predicted by change in health and other connected constructs, and how one might intervene to aid those who struggle with religious or spiritual challenges. Nonetheless, research momentum has grown, having already produced a wealth of information that underscores the need for greater attention to this domain. R/S struggle poses an important exception to generally positive overall associations between religion and well-being, though even R/S struggle may promote growth. This review offers a brief introduction to emerging psychological theory and research on R/S struggle with an emphasis on its relevance to wellness and illness. (shrink)

BackgroundDuring the last decade, the possibility for women to cryopreserve oocytes in anticipation of age-related fertility loss, also referred to as social egg freezing, has become an established practice at fertility clinics around the globe. In Europe, there is extensive variation in the costs for this procedure, with the common denominator that there are almost no funding arrangements or reimbursement policies. This is the first qualitative study that specifically explores viewpoints on the (lack of) reimbursement for women who had considered (...) to uptake at least one social egg freezing cycle in Belgium.MethodsTo understand the moral considerations of these women, drawing from twenty-one interviews, this paper integrates elements of a symbiotic empirical ethics approach and thematic analysis.ResultsWe identify four themes: (1) being confronted with unclear information; (2) financial costs as ongoing concern; (3) necessity of coverage; (4) extent of reimbursement. In the first theme, we found that some women were concerned about the lack of clear information about the cost of social egg freezing. In the second theme, we report moral sentiments of injustice and discrimination which some women attributed to their struggles and needs not being recognised. The third theme illustrates diverse views on reimbursement, ranging from viewing social egg freezing as an elective treatment not appropriate for reimbursement to preferences for greater public responsibility and wider access. Finally, we describe the participants’ varying proposals for partial reimbursement and the idea that it should not be made available for free.ConclusionsThis research adds important empirical insights to the bioethics debate on social egg freezing, in particular by presenting (potential) users’ views on the lack of reimbursement. While there is much more to say about the ethical and political complexities of the reimbursement of this procedure, our study highlighted the voices of (potential) users and showed that at least some of them would welcome the coverage of SEF through the public healthcare insurance.

The paper wishes to investigate the way Giles of Rome thought about logic: as a discipline, as a method, through an examination of the powers of logic, but also as a teaching subject. It tries to illuminate his views on logical education, and how he may have acted in favour of the latter as an Augustinian leader. It first offers a general presentation of the logical productions, from the 1270s to 1291. It then addresses the topic of logical education from (...) two viewpoints: by a look taken at Giles’ views on logic in the De regimine principum, and by a quick survey of the history of the teaching of logic in the studia of the Augustinian order from the mid-1280s on. The last section is dedicated to the philosophy and anthropology of logic. It tries to enlighten the originality of Giles’ s position, as a new departure taken from traditional theories regarding the absolute necessity of logic as a science, as an art, and as the underlying logic of all sciences, itself included. Rather than essentially necessary for any kind of philosophical endeavour, logic is presented a need for men, due to the fallible nature of his potential intellect. Rather than a science, it is described as a method for science which doesn’t use its more powerful instrument, i.e. the theory of scientific syllogism, since it proceeds in a non-demonstrative manner in the theory of demonstration. Logic and metaphysics are compared as respectively under and above special sciences. The last paragraph deals with the problem of the powers of logic in the context of metaphysical knowledge.

Recent debates about inequality have focused almost exclusively on the distribution of wealth and disparities in income, but little notice has been paid to the distribution of free time. Free time is commonly assumed to be a matter of personal preference, a good that one chooses to have more or less of. Even if there is unequal access to free time, the cause and solution are presumed to lie with the resources of income and wealth. In Free Time, Julie (...) Rose argues that these views are fundamentally mistaken. First, Rose contends that free time is a resource, like money, that one needs in order to pursue chosen ends. Further, realizing a just distribution of income and wealth is not sufficient to ensure a fair distribution of free time. Because of this, anyone concerned with distributive justice must attend to the distribution of free time. On the basis of widely held liberal principles, Rose explains why citizens are entitled to free time—time not committed to meeting life's necessities and instead available for chosen pursuits. The novel argument that the just society must guarantee all citizens their fair share of free time provides principled grounds to address critical policy choices, including work hours regulations, Sunday closing laws, public support for caregiving, and the pursuit of economic growth. Delving into an original topic that touches everyone, Free Time demonstrates why all citizens have, in the words of early labor reformers, a right to "hours for what we will.". (shrink)

Some interesting exceptions notwithstanding, the traditional logic of economic efficiency has long favored hierarchical forms of organization and disfavored democracy in business. What does the balance of arguments look like, however, when values besides efficient revenue production are brought into the picture? The question is not hypothetical: In recent years, an ever increasing number of corporations have developed and adopted socially responsible behaviors, thereby hybridizing aspects of corporate businesses and social organizations. We argue that the joint pursuit of financial and (...) social objectives warrants significant rethinking of organizational democracy’s merits compared both to hierarchy and to non-democratic alternatives to hierarchy. In making this argument, we draw on an extensive literature review to document the relative lack of substantive discussion of organizational democracy since 1960. And we draw lessons from political theory, suggesting that the success of political democracy in integrating diverse values offers some grounds for asserting parallel virtues in the business case.

In this paper, I examine a heretofore ignored critic of Descartes on the heterogeneity problem: Anton Wilhelm Amo. Looking at Amo’s critique of Descartes reveals a very clear case of a thinker who attempts to offer a causal system that is not a solution to the mind-body problem, but rather that transcends it. The focus of my discussion is Amo’s 1734 dissertation: The Apathy [ἀπάθεια] of the Human Mind or The Absence of Sensation and the Faculty of Sense in the (...) Human Mind and their Presence in our Organic and Living Body. Amo’s discussion of the interaction, or lack thereof, of the mind and body hinges on the essential feature he identifies for the human mind—apathy, that is, impassivity. In this work, Amo engages explicitly with Descartes’s writing, which allows us to more precisely see the nature of his agreement and disagreement with the Cartesian metaphysics of mind. I proceed by treating Amo’s five stated criteria for spirit-hood which, in turn, reveal the kinds of causal connections that are possible for embodied spirits on his view. My aim is threefold: To lay out what I take to be Amo’s view of and arguments for the five criteria he takes to be required for a substance to be spirit. To locate Amo’s agreement and disagreement with Descartes. To suggest that Amo’s view on mind-body interaction involves a kind of occasional causation. (shrink)

Julie K. Ward examines Aristotle's thought regarding how language informs our views of what is real. First she places Aristotle's theory in its historical and philosophical contexts in relation to Plato and Speusippus. Ward then explores Aristotle's theory of language as it is deployed in several works, including Ethics, Topics, Physics, and Metaphysics, so as to consider its relation to dialectical practice and scientific explanation as Aristotle conceived it.

Corporate Social Responsibility (CSR) programs are increasingly popular corporate marketing strategies. This paper argues that CSR programs can fall along a continuum between two endpoints: Institutionalized programs and Promotional programs. This classification is based on an exploratory study examining the variance of four responses from the consumer stakeholder group toward these two categories of CSR. Institutionalized CSR programs are argued to be most effective at increasing customer loyalty, enhancing attitude toward the company, and decreasing consumer skepticism. Promotional CSR programs are (...) argued to be more effective at generating purchase intent. Ethical and managerial implications of these preliminary findings are discussed. (shrink)

From the Supreme Court to the bedroom, privacy is an intensely contested interest in our everyday lives and privacy law. Some people appeal to privacy to protect such critical areas as abortion, sexuality, and personal information. Yet, privacy skeptics argue that there is no such thing as a right to privacy. I argue that we cannot abandon the concept of privacy. If we wish to avoid extending this elusive concept to cover too much of our lives or shrinking it to (...) cover too little, we must come to understand it. After exploring the privacy arguments of philosophers and constitutional and tort privacy law, I argue for a new definition of privacy and an explanation of its value that clarifies and resolves many of our conflicts. Privacy is critical because it allows us to protect a realm in which we can have intimate relations with others. (shrink)

One issue of dispute between methodological individualists and methodological holists is whether holist explanations are dispensable in the sense that individualist explanations are able to do their explanatory job. Methodological individualists say they are, whereas methodological holists deny this. In the first part of the paper, I discuss Elder-Vass’ version of an influential argument in support of methodological holism, the argument from emergence. I argue that methodological individualists should reject it: The argument relies on a distinction between individualist and holist (...) explanations that they find unacceptable and Elder-Vass’ reasons in support of his way of drawing this distinction are not good ones. In the second part, I examine what, if anything, would be good reasons in support of a particular way of differentiating between individualist and holist explanations. I propose that a good reason is one which shows, in an acceptable manner, that the distinction, drawn in the same way in all contexts, is useful from the perspective of offering explanations of the social world. I show that if this criterion is adopted, it will result in a fruitful reorientation of the whole debate between methodological individualists and methodological holists. (shrink)

In a recent article in this journal, Brian Alters argued that, given the many ways in which the nature of science is described and poor student responses to NOS instruments such as Nature of Scientific Knowledge Scale, Nature of Science Scale, Test on Understanding Science, and others, it is time for science educators to reconsider the standard lists of tenets for the NOS. Alters suggested that philosophers of science are authorities on the NOS and that consequently, it would be wise (...) to investigate their views of current NOS tenets. To that end, he conducted a survey of members of the Philosophy of Science Association, and, via various statistical techniques, made claims about the nature and extent of variation among philosophers of science regarding basic beliefs about the NOS. As three philosophers of science, we laud Alters’ attempt to understand philosophers of science’ view on the NOS. We believe, however, that his techniques for investigating this question are inappropriate and that consequently, several of his conclusions are unwarranted. In this comment, we will substantiate these criticisms. In addition, we will address some of the important questions that motivate Alters’ research and attempt to unravel the “byzantine complexity” of philosophical views about the NOS. We begin with our concerns regarding Alters’ research. We then provide a taxonomy of philosophic issues; and finally, we suggest some roles for philosophy of science in science teaching and the education of science teachers. (shrink)

The dominant theory of cross-disciplinarity represents multidisciplinarity as ‘lower’ or ‘less interesting’ than interdisciplinarity. In this paper, it is argued that this unfavorable representation of multidisciplinarity is ungrounded because it is an effect of the theory being incomplete. It is also explained that the unfavorable, ungrounded representation of multidisciplinarity is problematic: when someone adopts the dominant theory of cross-disciplinarity, the unfavorable representation supports the development of a preference for interdisciplinarity over multidisciplinarity. However, being ungrounded, the support the representation provides for (...) a preference for interdisciplinarity, is invalid. The issue is even more pressing because research policy makers and funding bodies are among the adopters of the theory, which means that there is a risk of policies reflecting an unjustified preference for interdisciplinarity over multidisciplinarity. This paper presents an improved version of the dominant theory of cross-disciplinarity, obtained by completing the original version with the information it was missing. Because the improved version is more neutral regarding the value of different types of cross-disciplinarity, it is better suited for use by research policy makers and funding bodies. (shrink)

In the recent methodological individualism-holism debate on explanation, there has been considerable focus on what reasons methodological holists may advance in support of their position. We believe it is useful to approach the other direction and ask what considerations methodological individualists may in fact offer in favor of their view about explanation. This is the background for the question we pursue in this paper: Why be a methodological individualist? We start out by introducing the methodological individualism-holism debate while distinguishing two (...) forms of methodological individualism: a form that says that individualist explanations are always better than holist accounts and a form that says that providing intervening individualist mechanisms always makes for better explanations than purely holist ones. Next, we consider four lines of reasoning in support of methodological individualism: arguments from causation, from explanatory depth, from agency, and from normativity. We argue that none of them offer convincing reasons in support of the two explanatory versions of individualism we consider. While there may well be occasions in which individualists’ favorite explanations are superior, we find no reason to think this always must be the case. (shrink)

Machine learning methods have recently created high expectations in the climate modelling context in view of addressing climate change, but they are often considered as non-physics-based ‘black boxes’ that may not provide any understanding. However, in many ways, understanding seems indispensable to appropriately evaluate climate models and to build confidence in climate projections. Relying on two case studies, we compare how machine learning and standard statistical techniques affect our ability to understand the climate system. For that purpose, we put five (...) evaluative criteria of understanding to work: intelligibility, representational accuracy, empirical accuracy, coherence with background knowledge, and assessment of the domain of validity. We argue that the two families of methods are part of the same continuum where these various criteria of understanding come in degrees, and that therefore machine learning methods do not necessarily constitute a radical departure from standard statistical tools, as far as understanding is concerned.

Mathematical models are often expected to provide not only predictions about the phenomenon that they represent, but also explanations. These explanations are answers to why-questions and particularly answers to why the predicted phenomenon should occur. For instance, models can be used to calculate when the next total solar eclipse will happen, and then to explain why it will take place on July 2, 2019. In this regard we can obtain explanations from a model if we can solve the model equations (...) which govern the phenomenon under study. But some equations have no explicit solution or are too complicated to solve. In these cases it is difficult for a... (shrink)
