An examination of British and French weights exchanged between the Royal Society and the Académie royale des sciences in the 1730s has led to a re‐assessment of the Elizabethan troy standards from the Exchequer and the suggestion that the mass of the troy pound has been revised upwards. In turn this is used to support the idea of an evolutionary relationship between the early bullion ounces of England, France, and the Low Countries.

May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that the (...) crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

There is little empirical evidence showing a direct link between a capacity for statistical learning (SL) and proficiency with natural language. Moreover, discussion of the role of SL in language acquisition has seldom focused on literacy development. Our study addressed these issues by investigating the relationship between SL and reading ability in typically developing children and healthy adults. We tested SL using visually presented stimuli within a triplet learning paradigm and examined reading ability by administering the Wide Range Achievement Test (...) (WRAT-4; Wilkinson & Robertson, 2006). A total of 38 typically developing children (mean age of 9;5 years, range 6;4–12;5) and 37 healthy adults (mean age of 21 years, range 18–34) were assessed. In children, SL was significantly related to reading ability. Importantly, this relationship was independent of grade and also age. The adult data, too, revealed that SL was significantly related to reading ability. A regression analysis of the combined child and adult data revealed that SL accounted for a unique amount of variance in reading ability, after age and attention had been taken into consideration. For the first time, this study provides empirical evidence that a capacity for more effective SL is related to higher reading ability in the general population. (shrink)

As legal scholar Ariela Dubler notes, the institution of marriage casts a long shadow across contemporary social life. Much more than a way of conferring social sanction on sexual and romantic relationships, marriage unlocks a wide range of social goods, from inheritance rights to medical records access. In addition, though, and as generations of feminists, queer activists, and others have made clear, this institution is part of a wider network of power relationships that it helps to shore up and conceal. (...) Critics most often point to the way the marital regime quietly reinforces patriarchal, bourgeois liberal, and heteronormative assumptions, hiding them in the shadow of putatively benign, private, and natural social structures. This article brings the overlooked connections between marriage and race out of the shadows and more fully into view. Using and refining a fourfold notion of racial invisibility developed in Taylor’s Black Is Beautiful, we consider two respects in which this ocularcentric metaphor for racialized epistemic short-circuiting is particularly appropriate for discussing the marital regime.

Lethal Autonomous Weapon Systems are here. Technological development will see them become widespread in the near future. This is in a matter of years rather than decades. When the UN Convention on Certain Conventional Weapons meets on 10-14th November 2014, well-considered guidance for a decision on the general policy direction for LAWS is clearly needed. While there is widespread opposition to LAWS—or ‘killer robots’, as they are popularly called—and a growing campaign advocates banning them outright, we argue the opposite. LAWS (...) may very well reduce suffering and death in war. Rather than banning them, they should be regulated, to ensure both compliance with international humanitarian law, and that this positive outcome occurs. This policy memo sets out the basic structure and content of the regulation required. (shrink)

Several themes can be identified in the commentaries. The first is that the climbing fibers may have more than one function; the second is that the climbing fibers provide sensory rather than motor signals. We accept the possibility that climbing fibers may have more than one function consequence(s)’ in the title. Until we know more about the function of the inhibitory input to the inferior olive from the cerebellar nuclei, which are motor structures, we have to keep open the possibility (...) that the climbing fiber signals can be a combination of sensory and motor signals.

À la différence des drones qui sont manoeuvrés à distance (...) mais comportent une part importante de discernement humain, il s’agit de machines programmées pour défendre, attaquer, ou tuer de manière autonome. Les auteurs, philosophes, préfèrent prévenir de leur prochaine diffusion et obtenir des Nations Unies leur régulation. Une campagne internationale propose plutôt leur interdiction. (shrink)

Yarkoni's analysis clearly articulates a number of concerns limiting the generalizability and explanatory power of psychological findings, many of which are compounded in infancy research. ManyBabies addresses these concerns via a radically collaborative, large-scale and open approach to research that is grounded in theory-building, committed to diversification, and focused on understanding sources of variation.

BackgroundThe COVID-19 pandemic has had a significant impact on the health system worldwide. The organ and tissue donation and transplantation (OTDT) system is no exception and has had to face ethical challenges related to the pandemic, such as risks of infection and resource allocation. In this setting, many Canadian transplant programs halted their activities during the first wave of the pandemic.MethodTo inform future ethical guidelines related to the COVID-19 pandemic or other public health emergencies of international concern, we conducted a (...) literature review to summarize the ethical issues.ResultsThis literature review identified three categories of ethical challenges. The first one describes the general ethical issues and challenges reported by OTDT organizations and transplantation programs, such as risks of COVID-19 transmission and infection to transplant recipients and healthcare professionals during the transplant process, risk of patient waitlist mortality or further resource strain where transplant procedures have been delayed or halted, and resource allocation. The second category describes ethical challenges related to informed consent in the context of uncertainty and virtual consent. Finally, the third category describes ethical issues related to organ allocation, such as social considerations in selecting transplant candidates.ConclusionThis literature review highlights the salient ethical issues related to OTDT during the current COVID-19 pandemic. As medical and scientific knowledge about COVID-19 increases, the uncertainties related to this disease will decrease and the associated ethical issues will continue to evolve. (shrink)

In De Anima III.8 Aristole asserts that "the soul is in a sense all things" because it becomes whatever is thought or perceived. Yet the relationship between the soul and an object of perception or thought is most likely not one of numerical identity. As Aristotle says, "The stone is not in the soul but, rather, form" . Now if soul-object relations cannot be explained solely in terms of numerical identity, it is incumbent upon Aristotle to state what other sense (...) of identity is being invoked. According to Aristotle, the relation obtaining between the soul and an object of perception or thought is one of representational isomorphism; e.g., just as middle-C may be instantiated both in a piano and in a tuning fork, the salient features of an object of perception or thought may be instantiated in the soul as well as in the extra-mental world.

In this thoughtful essay Wallulis argues that a rethinking of Gadamer's seminal claims about our historical situatedness is necessary if we are to have an adequate account of personal achievement. He argues that in stressing that we are the effect of tradition, Gadamer does not allow personal initiative its due. Wallulis wants to oppose a consciousness of "having been enabled" to what he sees as Gadamer's exclusive emphasis on a consciousness of being affected by history, as well as to Habermas's (...) notion of a consciousness oriented towards emancipation, that is, towards overcoming pseudo-natural constraints and attaining complete self-transparency. While sympathetic to Gadamer's hermeneutic critique of Habermas, Wallulis wants to offer a corrective to Gadamer's one-sided focus and thereby to elaborate a "hermeneutic of life history" that does justice to personal achievement.

This response reinforces several major themes in our target article: (a) the importance of sex-specific, within-sex variation in mating tactics; (b) the relevance of optimality thinking to understanding that variation; (c) the significance of special design for reconstructing evolutionary history; (d) the replicated findings that women's mating preferences vary across their menstrual cycle in ways revealing special design; and (e) the importance of applying market phenomena to understand the complex dynamics of mating. We also elaborate on three points: (1) Men (...) who have indicators of genetic fitness may provide more direct benefits when female demand for extra-pair and short-term sex is very low; (2) both men and women track ecological cues to make mating decisions; and (3) more research on female orgasm is needed.

Working within weak subsystems of second-order arithmetic Z2 we consider two versions of the Baire Category theorem which are not equivalent over the base system RCA0. We show that one version (B.C.T.I) is provable in RCA0 while the second version (B.C.T.II) requires a stronger system. We introduce two new subsystems of Z2, which we call RCA+ 0 and WKL+ 0, and show that RCA+ 0 suffices to prove B.C.T.II. Some model theory of WKL+ 0 and its importance in view of (...) Hilbert's program is discussed, as well as applications of our results to functional analysis. (shrink)

Let CKDT be the assertion that for every countably infinite bipartite graph G, there exist a vertex covering C of G and a matching M in G such that C consists of exactly one vertex from each edge in M. (This is a theorem of Podewski and Steffens [12].) Let ATR0 be the subsystem of second-order arithmetic with arithmetical transfinite recursion and restricted induction. Let RCA0 be the subsystem of second-order arithmetic with recursive comprehension and restricted induction. We show that (...) CKDT is provable in ART0. Combining this with a result of Aharoni, Magidor, and Shore [2], we see that CKDT is logically equivalent to the axioms of ATR0, the equivalence being provable in RCA0. (shrink)

We prove two embedding and extension theorems in the context of the constructive theory of metric spaces. The first states that Cantor space embeds in any inhabited complete separable metric space without isolated points, X, in such a way that every sequentially continuous function from Cantor space to ℤ extends to a sequentially continuous function from X to ℝ. The second asserts an analogous property for Baire space relative to any inhabited locally non-compact CSM. Both results rely on having careful (...) constructive formulations of the concepts involved.As a first application, we derive new relationships between “continuity principles” asserting that all functions between specified metric spaces are pointwise continuous. In particular, we give conditions that imply the failure of the continuity principle “all functions from X to ℝ are continuous”, when X is an inhabited CSM without isolated points, and when X is an inhabited locally non-compact CSM. One situation in which the latter case applies is in models based on “domain realizability”, in which the failure of the continuity principle for any inhabited locally non-compact CSM, X, generalizes a result previously obtained by Escardó and Streicher in the special case X = C[0, 1].As a second application, we show that, when the notion of inhabited complete separable metric space without isolated points is interpreted in a recursion-theoretic setting, then, for any such space X, there exists a Banach-Mazur computable function from X to the computable real numbers that is not Markov computable. This generalizes a result obtained by Hertling in the special case that X is the space of computable real numbers. (shrink)

The question of whether lies by those who govern are acceptable receives a clear focus and an ideal case in the Republic. Against C. D. C. Reeve, and T. C. Brickhouse and N. D Smith, I argue that the Republic’s apparent recommendation of administrative lies is incoherent. While lies may be a necessary part of the City’s administration, the process and practice of lying undermines that nature which is necessary for any suitable ruler – rendering the ideal impossible. I argue (...) that this analysis, while concerned with an ideal case, also applies to the political realist’s regrettable-but-necessary defence of such practices. (shrink)

This article identifies both prudence and antiprudence as options for rational people. Building upon Wiggins's "sensible subjectivism," the account offers an analysis of prudential emotions which are not rationally required but whose reasonableness need not be doubted. One result is that skepticism about prudence is avoidable. Another, as shown through examination of some of Parfit's worries about replication, is that prudence is autonomous from metaphysical theories of persons. It is also autonomous from morality, neither prudence nor morality being appropriately subordinated (...) to the other in a theory of rational choice. (shrink)

Adam Smith is perceived, through his best-known book, An Inquiry into the Nature and Causes of the Wealth of Nations, as the founder of economics as a science. His thought has shaped modern ideas about the market economy and the role of the state in relation to it. Yet Smith needs to be recognized as more than this, as a man of letters, moralist, historian, and critic, as well as an economist, if we are to get full value for his (...) ideas and perspectives in contemporary applications. Ian Simpson Ross is the biographer of Lord Kames, Smith's patron, and of the Scottish poet William Dunbar, and has edited, with E C Mossner, Smith's correspondence for the Glasgow edition of his works. In this, the first full-scale biography of Adam Smith for a hundred years, Ross brings his subject in to historical light as a thinker and author by examining his family circumstance, education, career, and social and intellectual circle, including David Hume and Francois Quesnay, revealed through his correspondence, archival documents, the reports of contemporaries, and the record of his publications. Readers will meet Smith as a student at a lively Glasgow and sleepy Oxford; freelance lecturer in rhetoric; innovative university teacher; tutor travelling abroad with a Duke; acclaimed political economist; policy advisor to governments during and after the American crisis; and finally, if paradoxically in view of his tenets, a Commissioner of Customs coping with the free traders in the smuggling business. This is the life of a Scottish moral philosopher whose legacy of thought concerns and affects us all. Its lively and informed account will appeal to those interested in the social and intellectual milieu of the eighteenth century, and in scottish history. Economists and philosophers will find much to read about the history of their disciplines, supported by full documentation. (shrink)

“Looking for Asian America shows real people engaged in the full range of human activity. This is no small accomplishment for the photographer or his subjects. For Asian Americans it is extraordinary to be merely ordinary. To others, even if not to themselves, Asian Americans appear to be contradictions of identity—a Chinese-Yankee is a knockoff.” —Frank H. Wu, from the Foreword In search of contemporary Asian America, celebrated photographer Wing Young Huie—the only member of his family not born in China—traveled (...) with his wife Tara through nearly forty states to explore and document the funny, touching, and sometimes strange intersection of Asian American and American cultures. Looking for Asian America illustrates their rich and surprising journey across the United States. Through Huie’s eyes, keenly aware of his own Midwestern roots and perspective, we witness such images as a Vietnamese Elvis, Miss Congeniality on her cell phone in San Francisco’s Chinatown, a Hmong street sign in rural North Carolina, a meditating Falun Gong protestor in Washington, D.C., a bubble tea Valley Girl, and a Chinese theme park in Orlando. Huie’s camera captures ABCs, FOAs, and a self-described “redneck” Chinese restaurant owner near the Okefenokee Swamp. Taken together the photographs reveal a complex portrait of the U.S. cultural landscape, and their dignified elegance invites a closer, deeper look. Accompanied by the personal reflections of both Wing and Tara Huie, the nearly one hundred spectacular photos tell a story that both mirrors and contradicts stereotypes of Asian Americans, ultimately questioning what it means to be ethnic and American in the twenty-first century. Wing Young Huie has received widespread acclaim for his works, including Lake Street USA, documenting the cultural landscape of his native Minnesota. He is a recipient of a Bush Artist Fellowship and two-time recipient of the McKnight Photography Fellowship. He lives in Minneapolis. Frank H.

The concept of teleonomy has been attracting renewed attention recently. This is based on the idea that teleonomy provides a useful conceptual replacement for teleology, and even that it constitutes an indispensable resource for thinking biologically about purposes. However, both these claims are open to question. We review the history of teleological thinking from Greek antiquity to the modern period to illuminate the tensions and ambiguities that emerged when forms of teleological reasoning interacted with major developments in biological thought. This (...) sets the stage for an examination of Pittendrigh’s (Adaptation, natural selection, and behavior. In: Roe A, Simpson GG (eds) Behavior and evolution. Yale University Press, New Haven, pp 390–416, 1958) introduction of “teleonomy” and its early uptake in the work of prominent biologists. We then explore why teleonomy subsequently foundered and consider whether the term may yet have significance for discussions of goal-directedness in evolutionary biology and philosophy of science. This involves clarifying the relationship between teleonomy and teleological explanation, as well as asking how the concept of teleonomy impinges on research at the frontiers of evolutionary theory.

We suggest that the cerebellum generates sensory or estimates based on outgoing motor commands and sensory feedback. Thus, it is not a motor pattern generator (HOUK et al.) but a predictive system which is intimately involved in motor behavior. This theory may explain the sensitivity of the climbing fibers to both unexpected external events and motor errors (SIMPSON et al.), and we speculate that unusual biophysical properties of the inferior olive might allow the cerebellum to develop multiple asynchronous sensory (...) estimates, [HOUK et al.; SIMPSON et al.; THACH].

We continue the work of [14, 3, 1, 19, 16, 4, 12, 11, 20] investigating the strength of set existence axioms needed for separable Banach space theory. We show that the separation theorem for open convex sets is equivalent to WKL$_0$ over RCA$_0$. We show that the separation theorem for separably closed convex sets is equivalent to ACA$_0$ over RCA$_0$. Our strategy for proving these geometrical Hahn-Banach theorems is to reduce to the finite-dimensional case by means of a compactness argument.

Our trust in the word of others is often dismissed as unworthy, because the illusory ideal of "autonomous knowledge" has prevailed in the debate about the nature of knowledge.

A mass problem is a set of Turing oracles. If P and Q are mass problems, we say that P is weakly reducible to Q if for all Y ∈ Q there exists X ∈ P such that X is Turing reducible to Y. A weak degree is an equivalence class of mass problems under mutual weak reducibility. Let [Formula: see text] be the lattice of weak degrees of mass problems associated with nonempty [Formula: see text] subsets of the Cantor (...) space. The lattice [Formula: see text] has been studied in previous publications. The purpose of this paper is to show that [Formula: see text] partakes of hyperarithmeticity. We exhibit a family of specific, natural degrees in [Formula: see text] which are indexed by the ordinal numbers less than [Formula: see text] and which correspond to the hyperarithmetical hierarchy. Namely, for each [Formula: see text], let hα be the weak degree of 0, the αth Turing jump of 0. If p is the weak degree of any mass problem P, let p* be the weak degree of the mass problem P* = {Y | ∃X ⊆ BLR )} where BLR is the set of functions which are boundedly limit recursive in X. Let 1 be the top degree in [Formula: see text]. We prove that all of the weak degrees [Formula: see text], [Formula: see text], are distinct and belong to [Formula: see text]. In addition, we prove that certain index sets associated with [Formula: see text] are [Formula: see text] complete. (shrink)

A major theme of the systems physiologists is the critical timing function of the cerebellum. However, the biophysicists do not appear to directly address the biophysical basis of the adaptive timing competence implicated in the physiological and behavioral data. Thus, the bridge between the macroscopic and microscopic data bases seems to be incomplete in a critical area. We report successful results from an attempt to add the missing part of the bridge. It comes in the form of a model of (...) how the second messenger system activated by parallel fiber inputs - the mGluR channel - can literally bridge the temporal gap between CS and CR, both in standard conditioning tasks and more generally, [CRÉPEL et al.; HOUK et al.; KANO; LINDEN; SIMPSON et al.; SMITH; THACH; VINCENT].

Many philosophers have appealed to the PSR in arguments for a being that exists a se, a being whose explanation is in itself. But what does it mean, exactly, for something to have its explanation ‘in itself’? Contemporary philosophers have said next to nothing about this, relying instead on phrases plucked from the accounts of various historical figures. In this article, I analyse five such accounts – those of Anselm, Aquinas, Descartes, Spinoza, and Leibniz – and argue that none are (...) satisfactory. Should we abandon or restrict the PSR, then? I think that would be hasty, for many reasons. I therefore consider the prospects of explaining everything, including God, given the constraints of certain features of good explanations, and conclude with several observations about future approaches.
