Beginning in the early 1990s, Third World Approaches to International Law scholarship (TWAIL) destabilized the mainstream narrative within international law that its doctrines were constituted by the historic search for order between formally equal state sovereigns. Instead, TWAIL scholars argued that the key constitutive dynamic of the discipline was the colonial experience, which continues to hold powerful sway over the legal architecture of global regulation whereby international law functions to perpetuate inequality and oppression. At the same time, however, TWAIL scholarship (...) regularly posits international law as an emancipatory force that may be mobilized on behalf of former colonized populations and other marginalized social identities. The rise of post-Marxist scholarship, and more generally, the turn to interdisciplinary within the profession in recent years offers an opportunity to analyze this curious paradox and construct alternative modes of analysis for future TWAIL scholarship. In the first section, the paper draws upon a diverse array of TWAIL scholars over the last thirty years to map the argumentative logic within TWAIL literature. In the second section, the paper incorporates debates and insights from complimentary academic disciplines to illuminate some blind spots within TWAIL’s central arguments, and potentially ‘radicalize’ its future possibility of critique against the growing inequality within global governance.

Although living conditions have improved throughout history, protest, at least in the last few decades, seems to have increased to the point of becoming a normal phenomenon in modern societies. Contributors to this volume examine how and why this is the case and argue that although problems such as poverty, hunger, and violations of democratic rights may have been reduced in advanced Western societies, a variety of other problems and opportunities have emerged and multiplied the reasons and possibilities for protest.

Retrieval practice, relative to further study, leads to long-term memory enhancement known as the “testing effect.” The neurobiological correlates of the testing effect at retrieval, when the learning benefits of testing are expressed, have not been fully characterized. Participants learned Swahili-English word-pairs and were assigned randomly to either the Study-Group or the Test-Group. After a week delay, all participants completed a cued-recall test while undergoing functional magnetic resonance imaging. The Test-Group had superior memory for the word-pairs compared to the Study-Group. (...) While both groups exhibited largely overlapping activations for remembered word-pairs, following an interaction analysis the Test-Group exhibited differential performance-related effects in the left putamen and left inferior parietal cortex near the supramarginal gyrus. The same analysis showed the Study-Group exhibited greater activations in the dorsal MPFC/pre-SMA and bilateral frontal operculum for remembered vs. forgotten word-pairs, whereas the Test-Group showed the opposite pattern of activation in the same regions. Thus, retrieval practice during training establishes a unique striatal-supramarginal network at retrieval that promotes enhanced memory performance. In contrast, study alone yields poorer memory but greater activations in frontal regions. (shrink)

An infinite lottery machine is used as a foil for testing the reach of inductive inference, since inferences concerning it require novel extensions of probability. Its use is defensible if there is some sense in which the lottery is physically possible, even if exotic physics is needed. I argue that exotic physics is needed and describe several proposals that fail and at least one that succeeds well enough.

Seventeenth-century “chance combinatorics” was a self-contained theory. It had an objective notion of chance derived from physical devices with chance properties, such as casts of dice, combinatorics to count chances and, to interpret their significance, a rule for converting these counts into fair wagers. It lacked a notion of chance as a measure of belief, a precise way to connect chance counts with frequencies and a way to compare chances across different games. These omissions were not needed for the theory’s (...) interpretation of chance counts: determining which are fair wagers. The theory provided a model for how indefinitenesses could be treated with mathematical precision in a special case and stimulated efforts to seek a broader theory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE SUBSTANTIAL UNITY OF MATERIAL SUBSTANCES ACCORDING TO JOHN POINSOT JOHN D. KRONEN The University of St. Thomas St. Paul, Minnesota EVERY SUBSTANCE metaphysician must answer several difficult questions peculiar to his or her ontology. In this paper I will examine John Poinsot's answer to two of these questions, one concerning the nature of the form of substantial composites, and one concerning which material objects are (...) substantial composites. I shall argue that Poinsot's answers to these questions show the untenability of a structuralist view of substantial form and of a reductive materialist view of living beings. But before considering these questions I must briefly outline Poinsot's view of what the general nature of substance is, as explained in his treatise on material logic.1 Poinsot's Account of Substance in General In the section of his Material Logic concerned with the categories Poinsot gives a succinct account of the nature of substance 1 Cursus Philosophicus thomisticus; vol. I, Ars logicae prima et secunda pars, ed. P. Beato Reiser (Turin, Italy: Marietti, 1820), Q. XV, pp. 523-527. It should be noted that I am not concerned in this paper with describing either the psychological origin of the notion of substance, or of justifying it against phenomenalism. My only aim is to show how such a view of substance leads to a certain notion of form when it is applied, so to speak, to material objects. For an interesting account of the origin of the concept of substance in Poinsot see John Deely, Tractatus De Signis: The Semiotic of John Poinsot (Los Angeles, Berkeley, and London: The University of California Press, 1985), p. 86, n. 16. Deely takes it that Poinsot has a deeper categorial scheme than that of Aristotle from which the latter's scheme "emerges," as it were. In this article, then, I am not concerned with that deeper scheme which Deely refers to in this interesting note. 599 600 JOHN D. KRONEN in general and of its relation to the supposit and to the act of existing. He notes that by " substance " narrowly considered is meant that kind of essence to "which it is due to exist in itself as opposed to that kind to which it is due to exist in another" (i.e., an accident).2 He defends this as the primary " definition " 3 of substance against the other definition of it which is " that which stands under accidents," on the grounds that a thing must exist in itself, at least ontologically speaking, before it can support accidents 4 and that to define substance as that which supports accidents is to define it in relation to other things, not itself. This point is important because many modern and contemporary philosophers who have attacked the notion of substance have done so by arguing that there are no beings which stand under accidents. For Poinsot this attack, even if successful, would show that there are no accidents, not that there are no substances. Poinsot insists that " substance " connotes a quiddity to which to exist in itself is due since actual existence does not belong to the essence of any created thing.5 Further, Poinsot insists that to exist in itself " connotes more than a mere negation of existing in another; rather it connotes a positive perfection." This is because to exist in a dependent way is to exist in an imperfect way, so to exist independently must be to exist in a more perfect way.6 Finally, Poinsot distinguishes between the substance and the supposit. The substance is the complete nature of the thing, while 2 Ibid., p. 523. a " Substance " as a supreme genus cannot strictly be defined since it cannot be differentiated from any higher genus. 4 Haec autem proprietas existendi per se intelligitur vel secundum considerationem absolutam et in ordine ad se, et sic dicitur subsistens, quasi non indignes alio ut sustentetur, sed in se sistens; vel dicitur secundum habitudinem ad alia, quatenus ilia sustentat in esse, et sic dicitur non solum subsistens, sed etiam substans.

Caputo speaks with a passion and a concern that are rare (...) in academic philosophy. His profound sense of humor deepens the passion of the viewpoints he develops." —Mark C.

The Surfactant, Positive Pressure, and Oxygenation Randomized Trial (SUPPORT) has been the focal point of many different criticisms regarding the ethics of the study ever since publication of the trial's findings in 2010 and 2012. In this article, we focus on a concern that the technical design and implementation details of the study were ethically flawed. While the federal Office Human Research Protections focused on the consent form, rather than on the study design and implementation, OHRP's critiques of the consent (...) form reveal views about the study design and implementation that we believe are fundamentally flawed. These criticisms about the design and implementation of SUPPORT, if generalized, become relevant concerns about these aspects of many comparative effectiveness research studies.Our analytical approach will be to use SUPPORT as a prime example of comparative effectiveness research and show why it challenges some prevailing assumptions about the riskiness of research. We will address five aspects of the study design and implementation: 1) randomization, 2) treatment by protocol, 3) choice of endpoints, 4) lack of a “standard care” control group, and 5) the use of altered oximeters. Examining these aspects will allow us to answer two specific central questions. The first is a methodological question with ethical implications: was the study designed in such a way as to answer the primary study question? The second question is whether the study design added or decreased risk to the babies enrolled in the study compared to babies who were not in the study. (shrink)

At the age of sixteen, Einstein imagined chasing after a beam of light. He later recalled that the thought experiment had played a memorable role in his development of special relativity. Famous as it is, it has proven difficult to understand just how the thought experiment delivers its results. It fails to generate problems for an ether-based electrodynamics. I propose that Einstein’s canonical statement of the thought experiment from his 1946 “Autobiographical Notes,” makes most sense not as an argument against (...) ether-based electrodynamics, but as an argument against “emission” theories of light.

The thesis that observation necessarily fails to determine theory is false in the sense that observation can provide overwhelming evidence for a particular theory or even a hypothesis within the theory. The saga of quantum discontinuity illustrates the power of evidence to determine theory and shows how that power can be underestimated by inadequate caricatures of the evidential case. That quantum discontinuity can save the phenomena of black body radiation is the widely known result, but it leaves open the possibilities (...) of other accounts. That these phenomena, with the aid of minimal assumptions, entail quantum discontinuity is the crucial but now largely forgotten result. It was first demonstrated by Ehrenfest and Poincaré in 1911 and 1912. (shrink)

In the exuberance that followed Einstein’s discoveries, philosophers at one time or another have proposed that his theories support virtually every conceivable moral in ontology. I present an opinionated assessment, designed to avoid this overabundance. We learn from Einstein’s theories of novel entanglements of categories once held distinct: space with time; space and time with matter; and space and time with causality. We do not learn that all is relative, that time in the fourth dimension in any non-trivial sense, that (...) coordinate systems and even geometry are conventional or that spacetime should be reduced ontologically to causal, spatio-temporal or other relations.

Abstract.Einstein learned from the magnet and conductor thought experiment how to use field transformation laws to extend the covariance of Maxwell’s electrodynamics. If he persisted in his use of this device, he would have found that the theory cleaves into two Galilean covariant parts, each with different field transformation laws. The tension between the two parts reflects a failure not mentioned by Einstein: that the relativity of motion manifested by observables in the magnet and conductor thought experiment does not extend (...) to all observables in electrodynamics. An examination of Ritz’s work shows that Einstein’s early view could not have coincided with Ritz’s on an emission theory of light, but only with that of a conveniently reconstructed Ritz. One Ritz-like emission theory, attributed by Pauli to Ritz, proves to be a natural extension of the Galilean covariant part of Maxwell’s theory that happens also to accommodate the magnet and conductor thought experiment. Einstein’s famous chasing a light beam thought experiment fails as an objection to an ether-based, electrodynamical theory of light. However it would allow Einstein to formulate his general objections to all emission theories of light in a very sharp form. Einstein found two well known experimental results of 18th and 19th century optics compelling (Fizeau’s experiment, stellar aberration), while the accomplished Michelson-Morley experiment played no memorable role. I suggest they owe their importance to their providing a direct experimental grounding for Lorentz‘ local time, the precursor of Einstein’s relativity of simultaneity, and doing it essentially independently of electrodynamical theory. I attribute Einstein’s success to his determination to implement a principle of relativity in electrodynamics, but I urge that we not invest this stubbornness with any mystical prescience. (shrink)

The thermodynamics of computation assumes that computational processes at the molecular level can be brought arbitrarily close to thermodynamic reversibility and that thermodynamic entropy creation is unavoidable only in data erasure or the merging of computational paths, in accord with Landauer’s principle. The no-go result shows that fluctuations preclude completion of thermodynamically reversible processes. Completion can be achieved only by irreversible processes that create thermodynamic entropy in excess of the Landauer limit.

The duality of truth and falsity in a Boolean algebra of propositions is used to generate a duality of belief and disbelief. To each additive probability measure that represents belief there corresponds a dual additive measure that represents disbelief. The dual measure has its own peculiar calculus, in which, for example, measures are added when propositions are combined under conjunction. A Venn diagram of the measure has the contradiction as its total space. While additive measures are not self-dual, the epistemic (...) state of complete ignorance is represented by the unique, monotonic, non-additive measure that is self-dual in its contingent propositions. Convex sets of additive measures fail to represent complete ignorance since they are not self-dual. (shrink)

We address concerns raised by Maul (2012) regarding the validity of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). We respond to requests for clarifications of our model, and explain why the MSCEIT’s scoring methods stand up to scrutiny and why many reported reliabilities of the MSCEIT may be underestimates, using reanalyses of the test’s standardization sample of N = 5,000 to illustrate our point. We also organize findings from four recent articles that provide evidence for the MSCEIT’s validity based on its (...) relations with other tests. (shrink)

This, the first of two linked papers, presents the Buddha's analysis of the nature and origins of dukkha (suffering) as a basis for understanding the ways in which mindfulness can transform suffering. The First and Second of the Buddha's Four Noble Truths are presented in a way that has proved helpful to teachers of mindfulness-based applications. These Truths offer a framework of understanding that can guide the application of mindfulness to stress and emotional disorders, while stressing the continuity and inevitability (...) of the experience of dukkha in clients, teachers, and those primarily seeking a new way of being. The crucial involvement of self-view and identification with experience are emphasized. (shrink)

'This book is a model of philosophical and Heideggerian scholarship.

John Barrow is increasingly recognized as one of our most elegant and accomplished science writers, a brilliant commentator on cosmology, mathematics, and modern physics. Barrow now tackles the heady topic of impossibility, in perhaps his strongest book yet. Writing with grace and insight, Barrow argues convincingly that there are limits to human discovery, that there are things that are ultimately unknowable, undoable, or unreachable. He first examines the limits on scientific inquiry imposed by the deficiencies of the human mind: (...) our brain evolved to meet the demands of our immediate environment, Barrow notes, and much that lies outside this small circle may also lie outside our understanding. Barrow investigates practical impossibilities, such as those imposed by complexity, uncomputability, or the finiteness of time, space, and resources. Is the universe finite or infinite? Can information be transmitted faster than the speed of light? The book also examines the deeper theoretical restrictions on our ability to know, including Godel's theorem--which proved that there were things that could not be proved--and Arrow's Impossibility theorem about democratic voting systems. Finally, having explored the limits imposed on us from without, Barrow considers whether there are limits we should impose upon ourselves. For instance, if the secrets of the atom are to be found only by recreating extreme environments at great financial cost, just how much should we devote to that quest? Weaving together this intriguing tapestry, he illuminates some of the most profound questions of science, from the possibility of time travel to the very structure of the universe. (shrink)

Most bioethicists and professional medical societies condemn the practice of ?slow codes.? The American College of Physicians ethics manual states, ?Because it is deceptive, physicians or nurses should not perform half-hearted resuscitation efforts (?slow codes?).? A leading textbook calls slow codes ?dishonest, crass dissimulation, and unethical.? A medical sociologist describes them as ?deplorable, dishonest and inconsistent with established ethical principles.? Nevertheless, we believe that slow codes may be appropriate and ethically defensible in situations in which cardiopulmonary resuscitation (CPR) is likely (...) to be ineffective, the family decision makers understand and accept that death is inevitable, and those family members cannot bring themselves to consent or even assent to a do-not-resuscitate (DNR) order. In such cases, we argue, physicians may best serve both the patient and the family by having a carefully ambiguous discussion about end-of-life options and then providing resuscitation efforts that are less vigorous or prolonged than usual.

This article draws on the sociology of expectations to examine the construction of expectations of ‘ethical AI’ and considers the implications of these expectations for communication governance. We first analyse a range of public documents to identify the key actors, mechanisms and issues which structure societal expectations around artificial intelligence and an emerging discourse on ethics. We then explore expectations of AI and ethics through a survey of members of the public. Finally, we discuss the implications of our findings for (...) the role of AI in communication governance. We find that, despite societal expectations that we can design ethical AI, and public expectations that developers and governments should share responsibility for the outcomes of AI use, there is a significant divergence between these expectations and the ways in which AI technologies are currently used and governed in large scale communication systems. We conclude that discourses of ‘ethical AI’ are generically performative, but to become more effective we need to acknowledge the limitations of contemporary AI and the requirement for extensive human labour to meet the challenges of communication governance. An effective ethics of AI requires domain appropriate AI tools, updated professional practices, dignified places of work and robust regulatory and accountability frameworks. (shrink)

Einstein insisted throughout his life that the signal achievement of his general theory of relativity was its general covariance. How are we to reconcile this with the now common view that general covariance merely expresses a definition, our freedom to label events with any set of numbers we like? There is, I believe, a natural reading for Einstein's claims that does make perfect sense. It requires us to adopt a physical interpretation of relativity theory that is now no longer popular, (...) so the natural reading will no longer have intrinsic interest. It will, however, allow us to make sense of Einstein's claims and his program. (shrink)

John D. Caputo explores the very roots of religious thinking in this thought-provoking book. Compelling questions come up along the way: 'What do I love when I love my God?' and 'What can Star Wars tell us about the contemporary use of religion?' Why is religion for many a source of moral guidance in a postmodern, nihilistic age? Is it possible to have 'religion without religion'? Drawing on contemporary images of religion, such as Robert Duvall's film _The Apostle_, Caputo (...) also provides some fascinating and imaginative insights into religious fundamentalism. (shrink)

In a formal theory of induction, inductive inferences are licensed by universal schemas. In a material theory of induction, inductive inferences are licensed by facts. With this change in the conception of the nature of induction, I argue that the celebrated “problem of induction” can no longer be set up and is thereby dissolved. Attempts to recreate the problem in the material theory of induction fail. They require relations of inductive support to conform to an unsustainable, hierarchical empiricism.

Thought experiments are ordinary argumentation disguised in a vivid pictorial or narrative form. This account of their nature will allow me to show that empiricism has nothing to fear from thought experiments. They perform no epistemic magic. In so far as they tell us about the world, thought experiments draw upon what we already know of it, either explicitly or tacitly; they then transform that knowledge by disguised argumentation. They can do nothing more epistemically than can argumentation. I defend my (...) account of thought experiments in Section 3 by urging that the epistemic reach of thought experiments turns out to coincide with that of argumentation and that this coincidence is best explained by the simple view that thought experiments just are arguments. Thought experiments can err—-a fact to be displayed by the thought experiment - anti thought experiment pairs of Section 2. Nonetheless thought experiments can be used reliably and, I urge in Section 4., this is only possible if they are governed by some very generalized logic. I will suggest on evolutionary considerations that their logics are most likely the familiar logics of induction and deduction, recovering the view that thought experiment is argumentation. Finally in Section 5 I defend this argument based epistemology of thought experiments against competing accounts. I suggest that these other accounts can offer a viable epistemology only insofar as they already incorporate the notion that thought experimentation is governed by a logic, possibly of very generalized form.
