Sex differences in reproductive strategy and the sexual division of labor resulted in selection for and maintenance of sexual dimorphism across a wide range of characteristics, including body size, hormonal physiology, behavior, and perhaps spatial abilities. In laboratory tasks among undergraduates there is a general male advantage for navigational and mental-rotation tasks, whereas studies find female advantage for remembering item locations in complex arrays and the locations of plant foods. Adaptive explanations of sex differences in these spatial abilities have focused (...) on patterns of differential mate search and routine participation in distinct subsistence behaviors. The few studies to date of spatial ability in nonindustrial populations practicing subsistence lifestyles, or across a wider age range, find inconsistent results. Here we examine sex- and age-based variation in one kind of spatial ability related to navigation, dead-reckoning, among Tsimane forager horticulturalists living in lowland Bolivia. Seventy-three participants (38 male) aged 6–82 years pointed a handheld global positioning system (GPS) unit toward the two nearest communities and the more distant market town. We find no evidence of sex differences in dead reckoning (p = 0.47), nor do we find any evidence of age-related decline in dead-reckoning accuracy (p = 0.28). Participants were significantly more accurate at pointing toward the market town than toward the two nearest villages despite its being significantly farther away than the two nearest communities. Although Tsimane do show sexual dimorphism in foraging tasks, Tsimane women have extensive daily and lifetime travel, and the local environment lacks directional cues that typically enhance male navigation. This study raises the possibility that greater similarity in mobility patterns because of overlapping subsistence strategies and activities may result in convergence of some male and female navigation abilities.

In early 2020, a number of countries developed and published intensive care triage guidelines for the pandemic. Several of those guidelines, especially in the UK, encouraged the explicit assessment...

Imagine that we are considering whether our healthcare system (or insurer) should fund treatment or procedure X. One factor that may be cited is that of so-called ‘medical necessity’. The claim would be that treatment X should be eligible for funding if it is medically necessary, but ineligible if this does not apply. Similarly, (and relevant to the debates in this special issue), if considering whether a particular treatment should be ethically and/or legally permitted, we may wish to distinguish between (...) cases where the treatment is medically necessary, and those were it is not. But what do we mean by this concept? Here I will propose and briefly defend one plausible and practical definition. (shrink)

The debate about positive and negative claims of conscience is, in large part, about ethical consistency. In this commentary I argue that there can be differences between conscientious provision of treatment and conscientious nonprovision of treatment that are ethically relevant. However, in many cases, including those described in this commentary, there is not sufficient ethical reason to treat them differently. This means that asymmetrical conscientious objection policies are potentially unjustified.

This paper is partly to get rid of some irritation which I have felt at the quite common tendency of philosophers to elucidate (for example) ‘is red’ in terms of ‘looks red’. For a relatively recent example see, for example, Frank Jackson and Robert Pargetter, ‘An Objectivist′s Guide to Subjectivism about Colour’. However rather than try to make a long list of references, I would rather say ‘No names, no pack drill’. I have even been disturbed to find the use (...) of the words ‘looks red’ that I am opposing ascribed to me by Keith Campbell in his useful article ‘David Armstrong and Realism about Colour’. I am not saying that such talk is necessarily wrong. Talk of ‘looks red’ may be a way of harmlessly referring to the behavioural discriminations with respect to colour of a human percipient. Where it is dangerous, at least to those of us who wish to argue for a broadly physicalist account of the mind, is that it may have concealed overtones of reference to epiphenomenal and irreducibly psychic properties of experiences. Moreover even if it does not do so it may be fence sitting on this issue and liable to misinterpretation. (shrink)

We study logical systems for reasoning about equations involving recursive definitions. In particular, we are interested in "propositional" fragments of the functional language of recursion FLR [18, 17], i.e., without the value passing or abstraction allowed in FLR. The "pure," propositional fragment FLR$_0$ turns out to coincide with the iteration theories of [1]. Our main focus here concerns the sharp contrast between the simple class of valid identities and the very complex consequence relation over several natural classes of models.

This handbook presents a much-needed and comprehensive exploration of the rapidly growing fields of animal welfare and law. In recent years there has been increasing attention paid to our complex, multifaceted relationships with other animals, and in particular, the depth and breadth of various societal uses of animals. This has led to a reconsideration of their moral and social status, which has sometimes challenged the interests of those who use animals. In such a contested domain, sound evidence and reasoning become (...) particularly important. Through firm commitment to such principles, this book explores the biological foundations for the moral consideration of animals, and for evolving conceptualisations of animal welfare. It reviews in detail the welfare concerns associated with numerous forms of animal use. The inclusion of key recent developments such as climate change, pandemics and antimicrobial resistance, ensure this text is among the most current in its field. The ethical implications of the various uses of animals by society are considered, and chapters provide important recommendations for reforms of practice, law or policy. The status of animal law internationally, and in major world regions, is reviewed. Finally, the book considers human behavioural change, and strategies for improving stakeholder communication and education. The handbook is essential reading for students and scholars of animal welfare, animal law and animal ethics everywhere, and for policymakers and other professionals working in the animal welfare sector.

Messianic peacemakers: Intertextual relationships between Zechariah 9-14 and the Gospel of Matthew. This article deals with images of war, violence and peace and with the role of messianic leaders in Deutero-Zechariah and the way in which texts from Zechariah 9–14 have been interpreted in the Gospel of Matthew. The first section describes the lines of meaning in Zechariah 9–14 on the basis of word fields related to violence and universal peace. The second section discusses Deutero-Zechariah’s own position in the development (...) of messianic expectations in Old Testament texts. In the third section, the question is asked how the meaning of texts from Zechariah 9–14 about messianic leaders has been influenced by earlier prophetic texts, and how these texts in their turn have been transformed and updated in the Gospel of Matthew, which contains explicit quotations from Deutero-Zechariah in 21:5; 26:15; 26:31 and 27:9–10. The fourth section summarises some interesting semantic shifts appearing in Matthew’s gospel compared to Deutero-Zechariah. Moreover, some critical comments are presented against the idea defended in some recent studies that there is a sharp tension between Jesus’s role in Matthew as the bringer of a peaceful ethical message, and his violent and vindictive role at the final judgement. At the end of this article, the burning question is raised whether Zechariah’s and Matthew’s messages, both of which are characterised by a certain degree of exclusivity, can play a constructive role in modern multi-religious discussions about common roads leading to global peace.

Since the Global Financial Crisis, a surge of interest in the use of finance as a tool to address social and economic problems suggests the potential for a generational shift in how the finance industry operates and is perceived. J. C. de Swaan seeks to channel the forces of well-intentioned finance professionals to improve finance from within and help restore its focus on serving society. Drawing from inspiring individuals in the field, de Swaan proposes a framework for pursuing a viable (...) career in finance while benefiting society and upholding humanistic values. In doing so, he challenges traditional concepts of success in the industry. This will also engage readers outside of finance who are concerned about the industry's impact on society. (shrink)

It is a pleasure for me to give this opening address to the Royal Institute of Philosophy Conference on ‘Explanation’ for two reasons. The first is that it is succeeded by exciting symposia and other papers concerned with various special aspects of the topic of explanation. The second is that the conference is being held in my old alma mater, the University of Glasgow, where I did my first degree. Especially due to C. A. Campbell and George Brown there was (...) in the Logic Department a big emphasis on absolute idealism, especially F. H. Bradley. My inclinations were to oppose this line of thought and to espouse the empiricism and realism of Russell, Broad and the like. Empiricism was represented in the department by D. R. Cousin, a modest man who published relatively little, but who was of quite extraordinary philosophical acumen and lucidity, and by Miss M. J. Levett, whose translation of Plato's Theaetetus formed an important part of the philosophy syllabus. (shrink)

Can metaphysics yield the consolations of philosophy? One possibility, defended by Derek Parfit, is that reflection on the nature of identity and time could diminish both fear of death and grief. In this paper, I assess the prospect of such consolation, focussing especially on attempts to console a grieving third party. A shift to a reductionist view of personal identity might mean that death is less threatening. However, there is some evidence to suggest that such a shift does not necessarily (...) translate into less death anxiety. Moreover, applied to grief at loss of another, such a perspective may be misdirected. A temporally neutral perspective offers a theoretically powerful way of reducing the sense of loss at being separated in time from a loved one. However, it is unclear whether it is psychologically possible to achieve. Even if it were possible, it may not diminish the pain of separation.I identify a serious challenge to philosophical consolation for grief. The greater the consolation that is offered, the greater the risk of losing important attachments and the less it may be psychologically accessible. (shrink)

In this essay I contrast Freud’s account of mourning in Mourning and Melancholia to that of Merleau-Ponty in Phenomenology of Perception. In suggesting a somatic as well as a psychic response, Merleau-Ponty, I argue, more accurately accounts for the ways in which we experience loss and why, contrary to Freud’s suggestion, mourning’s work is never completed.

Originally published in 1944, this book was originally intended as a continuation of the 1943 publication Nautical Mathematics, which is also reissued in this series. In it, the principles set out in Nautical Mathematics are given practical applications, and the text is supplied with exercises to test and clarify the lessons. This book will be of value to anyone with an interest in the history of education in the forces during WWII.

According to Mark 6:14–29, John the Baptist was beheaded by the order of Herod Antipas. This dramatic event became inevitable after a cunning interplay between Herodias and her daughter, who remains nameless in the New Testament. According to Flavius Josephus, she was called Salome ( Jewish Antiquities XVIII, 5.4 § 136–137), and under that name, she went down in history. For the sake of convenience, I also call her ‘Salome’ in this article. Salome is the Greek form of the Hebrew (...) name Shlomith, which was very popular in early Judaic times and means ‘she who brings peace and tranquillity’. Unlike the faithful women elsewhere in Mark’s gospel (5:21–43; 7:24–30; 14:3–9), Herodias and her daughter are not exactly models of virtue. Yet, it is questionable as to whether they are both thoroughly bad and whether they are both equally responsible for the murder of John. This article does not provide a historical reconstruction of what exactly happened at the court of Herod Antipas, but it contains a narrative analysis of what happened in the court of Herod Antipas. This narrative analysis is followed by an intertextual approach in the second part of this article. Firstly, I will compare Mark’s story with what Flavius Josephus tells about the beheading of John. Thereafter, I will highlight the roles of Herodias and Salome in the play Salome by Oscar Wilde from 1894, which, in turn, forms the basis of the libretto for the opera Salome by Richard Strauss from 1905. Do we encounter in these modern artistic recreations (Neuschöpfungen) only transformations of Mark’s story, or also transgressions in which Wilde and Strauss have largely replaced the original meaning of the story with new meaning?

What are we to make of the cultural nonconformity of hardcore/punks? Is there any ethical value in the pursuit of cultural nonconformity? Distinct moral justifications can be teased from the lyrics of the hardcore/punk bands that we have grown up with and still love. The best explanation of what makes cultural nonconformity morally valuable, we believe, comes from John Stuart Mill: that it opens up new cultural space to oneself and to others, permitting "new and original experiments of living.".

This article is mainly concerned to summarise a fairly well articulated position on the philosophy of science which may be extracted from scattered passages in quine's "word and object." (1) there is no sharp line between philosophy and science, Or between science and mathematics, Or between science and common sense. (2) abstract mathematical entities are theoretical posits just as electrons are. (3) epistemology is a branch of biology. (4) quine's earlier instrumentalism has given way to a scientific realism. (5) quine's (...) philosophy of space-Time is briefly discussed. (6) an extensional language is adequate for science. (shrink)
