This paper argues that there are important irrational elements to love. In the philosophical literature, we typically find that love is either thought of as rational or arational and that any irrational elements are thought to be defective, or extraneous to love itself. We argue, on the contrary, that irrationality is in part connected to what we find valuable about love. -/- We focus on 3 basic elements of love: -/- 1) Whom you love 2) How much you love them (...) 3) How much of a role love plays in your life -/- And in each case, we argue that love can be irrational and valuable.

This volume features original essays on the philosophy of love. The essays are organized thematically around the past, present, and future of philosophical thinking about love. In section I, the contributors explore what we can learn from the history of philosophical thinking about love. The chapters cover Ancient Greek thinkers, namely Plato and Aristotle, as well as Kierkegaard's critique of preferential love and Erich Fromm's mystic interpretation of sexual relations. Section II covers current conceptions and practices of love. These chapters (...) explore how love changes over time, the process of falling in love, envy in romantic partnerships, and a new interpretation of grand-parental love. Finally, Section III looks at the future of love. These chapters address technological developments related to love, such as algorithm-driven dating apps and robotic companions, as well as the potential of polyamory as a future romantic ideal. This book will be of interest to researchers and advanced students in moral philosophy and social and political philosophy who are working on issues related to philosophy of love. (shrink)

This symposium brings into conversation normative political theory on migration and critical border/migration studies, with a particular focus on digital border control technology. Normative theorists have long been concerned with questions about the extent and nature of control over migration that the state should exercise, and the balance of rights and duties between states and migrants. To date, however, there has been little reflection among such theorists on digital border control technology. Critical border/migration studies scholars, on the other hand, have (...) paid considerable attention to the rapid development of digital technology in the border control/mobility management space, and revealed a range of problems with the technology itself and the ways it is deployed. What has thus far been lacking, however, is sustained ethical reflection on what should be done about the use of this technology. The papers in this symposium thus seek to bring these two groups of scholars together and to prompt what we hope will be a sustained conversation on these rapidly evolving and deeply problematic practices. This introduction contextualises the issue at the heart of this symposium – the rapid expansion of digital border controls and the ethical challenges that these pose – and offers brief summaries of the contributions.

Normative debates on migration control, while characterised by profound disagreement, do appear to agree that the state has at least a prima facie right to prevent the entry of security threats. While concern is sometimes raised that this ‘security exception’ can be abused, there has been little focus by normative theorists on concrete practices of security, and how we can determine what a ‘principled’ use of the security exception would be. I argue that even if states have a right to (...) prevent migrants from entering on grounds of security, the practices required to implement this right will likely compromise core liberal democratic values in ways that have not been sufficiently appreciated. I draw on literature from Science and Technology Studies and Critical Security Studies to examine the proliferation of digital border control technologies which are increasingly dominating state security practices, and explain the challenges these technologies pose to non-discrimination, liberty and equality. I also highlight the difficulties of taking these principles as presumptive limitations on the operation of the security exception. A more sustained conversation among ethical theorists is needed to address the profound ethical challenges that the ever-increasing use of these technologies poses, particularly in pursuit of security.

Normative theorists of migration are beginning to shift their focus away from an earlier obsession with whether the ‘liberal' or ‘legitimate’ state should have a right to exclude, and toward evaluation of how states engage in immigration control. However, with some notable exceptions – such as work of Rebecca Buxton, David Owen, Serena Parekh, and Alex Sager – this work tends not to focus on the global coordination of such control, and is still largely concerned with issues of membership. In (...) this paper I aim to show the value of shifting normative attention to the fundamentally interdependent nature of state control of migration, and the management of all forms of movement – not just settlement. This global management is greatly facilitated by the rapid digitisation of border controls. As such, I outline three aspects of the way digital border controls work – profiling, biometric identification, and the data sharing practices upon which they rest – and highlight ethical challenges of accountability, consent and the reach of the state, and entrenching global inequalities in access to movement. Ultimately, I hope to show that the globally interconnected nature of migration management is a combination of practices that normative theorists of migration should turn their attention to.

Natasha McKeever argues that prima facie, a friends-with-benefits relationship can be, at the same time, a good friendship. This is because sex is compatible with friendship in that it can complement and potentially even strengthen the three core characteristics of friendship: mutual liking, mutual caring, and mutual sharing. She acknowledges that, by generating uncertainty and having the potential to generate feelings of romantic love, sex does pose risks to friendship. However, she argues that while these risks are significant considerations, (...) they can be mitigated and managed and so do not provide strong reasons against friends-with-benefits relationships.

Particle indistinguishability has always been considered a purely quantum mechanical concept. In parallel, indistinguishable particles have been thought to be entities that are not properly speaking objects at all. I argue, to the contrary, that the concept can equally be applied to classical particles, and that in either case particles may (with certain exceptions) be counted as objects even though they are indistinguishable. The exceptions are elementary bosons (for example photons).

We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all finite-dimensional Hilbert spaces, is not in conflict with Leibniz's Principle of the Identity of Indiscernibles (PII). We discern the fermions by means of physically meaningful, permutation-invariant categorical relations, i.e. relations independent of the quantum-mechanical probabilities. If, indeed, probabilistic relations are permitted as well, we argue that similar bosons can also be discerned in all (...) their admissible states; but their categorical discernibility turns out to be a state-dependent matter. In all demonstrated cases of discernibility, the fermions and the bosons are discerned (i) with only minimal assumptions on the interpretation of quantum mechanics; (ii) without appealing to metaphysical notions, such as Scotusian haecceitas, Lockean substrata, Postian transcendental individuality or Adamsian primitive thisness; and (iii) without revising the general framework of classical elementary predicate logic and standard set theory, thus without revising standard mathematics. This confutes: (a) the currently dominant view that, provided (i) and (ii), the quantum-mechanical description of such composite physical systems always conflicts with PII; and (b) that if PII can be saved at all, the only way to do it is by adopting one or other of the thick metaphysical notions mentioned above. Among the most general and influential arguments for the currently dominant view are those due to Schrodinger, Margenau, Cortes, Dalla Chiara, Di Francia, Redhead, French, Teller, Butterfield, Giuntini, Mittelstaedt, Castellani, Krause and Huggett. We review them succinctly and critically as well as related arguments by van Fraassen and Massimi. (shrink)

I show that frequentism, as an explanation of probability in classical statistical mechanics, can be extended in a natural way to a decoherent quantum history space, the analogue of a classical phase space. The result is a form of finite frequentism, in which Gibbs’ concept of an infinite ensemble of gases is replaced by the quantum state expressed as a superposition of a finite number of decohering microstates. It is a form of finite and actual frequentism (as opposed to hypothetical (...) frequentism) insofar as all the microstates exist, in keeping with the decoherence-based Everett interpretation, and some versions of pilot-wave theory.

The Politics is one of the most influential texts in the history of political thought, and it raises issues which still confront anyone who wants to think seriously about the ways in which human societies are organized and governed. The work of one of the world's greatest philosophers, it draws on Aristotle's own great knowledge of the political and constitutional affairs of the Greek cities. By examining the way societies are run - from households to city states - Aristotle establishes (...) how successful constitutions can best be initiated and upheld. For this edition Sir Ernest Barker's fine translation, which has been widely used for nearly half a century, has been extensively revised to meet the needs of the modern reader. The accessible introduction and clear notes by R F Stalley examine the historical and philosophical background of the work and discuss its significance for modern political thought. (shrink)

Refugees and asylum seekers may experience challenges related to pre-arrival experiences, structural disadvantage after migration and during resettlement requiring the need for special protection when participating in research. The aim was to review if and how people with refugee and asylum seeker backgrounds have had their need for special protection addressed in national and international research ethics guidelines. A systematic search of grey literature was undertaken. The search yielded 2187 documents of which fourteen met the inclusion criteria. Few guidelines addressed (...) specific ethical considerations for vulnerable groups much less people with refugee and asylum seeker backgrounds. One guideline explicitly addressed vulnerability for refugees and asylums seekers. To ensure members of ethics committees and researchers consider the potential challenges of conducting research with these groups, guidelines may need to be supplemented with a refugee and asylum seeker specific research ethics framework. Such a framework may be necessary to optimally protect people with refugee and asylum seeker backgrounds in research. (shrink)

Creativity is an imperative need of the twenty-first century, and it seems to be a skill that will monopolize interest for many years. It is, in substance, a newly established scientific field and despite attempts to encroach on the science of psychology, its origin and functions have not been probed yet. Still, it continues to be researched, with ever-increasing vigor, almost in every area of science and action, with the main scope of potential exploitation being education. The philosophical foundation of (...) creativity has not reached the depths that one would expect, and most scientists-thinkers (and... (shrink)

This paper describes how to ethically conduct research with Black populations at the intersection of COVID-19 and the Black Lives Matter movement. We highlight the issues of historical mistrust in the USA and how this may impact Black populations’ participation in COVID-19 vaccination trials. We provide recommendations for researchers to ethically engage Black populations in research considering the current context. Our recommendations include understanding the impact of ongoing trauma, acknowledging historical context, ensuring diverse research teams and engaging in open and (...) honest conversations with Black populations to better address their needs. The core of our recommendation is recognising the impact of trauma in our research and health care practices. (shrink)

Asexuality is overlooked in the philosophical literature and in wider society. Such neglect produces incomplete or inaccurate accounts of romantic life and harms asexual people. We develop an account of asexuality to redress this neglect and enrich discussion of romantic life. Asexual experiences are diverse. Some asexual people have sex; some have romantic relationships in the absence of sex. We accept the common definition of asexuality as the absence of sexual attraction and explain how sexual attraction and sexual desire differ (...) by giving an affordance‐like account of sexual attraction. Armed with that distinction, we show that asexuality is clearly different from celibacy or disorders of desire and that some existing philosophical theories of sexual desire struggle to accommodate asexual sexuality. We then build on asexual testimony about the diversity of non‐sexual attractions to answer two common objections levelled at asexual romance: that romantic relationships require sexual attraction or that sex in the absence of sexual attraction is insufficiently focused on someone as an individual. Finally, we describe some of the ways asexuality has been erased or denigrated in society, and the specific injustices and harms that result. (shrink)

Aversive autobiographical memories sometimes prompt maladaptive emotional responses and contribute to affective dysfunction in anxiety and depression. One way to regulate the impact of such memories is to create a downward counterfactual thought–a mental simulation of how the event could have been worse–to put what occurred in a more positive light. Despite its intuitive appeal, counterfactual thinking has not been systematically studied for its regulatory efficacy. In the current study, we compared the regulatory impact of downward counterfactual thinking, temporal distancing, (...) and memory rehearsal in 54 adult participants representing a spectrum of trait anxiety. Participants recalled regretful experiences and rated them on valence, arousal, regret, and episodic detail. Two to six days later, they created a downward counterfactual of the remembered event, thought of how they might feel about it 10 years from now, or simply rehearsed it. A day later, participants re-rated the phenomenological characteristics of the events. Across all participants, downward counterfactual thinking, temporal distancing, and memory rehearsal were equally effective at reducing negative affect associated with a memory. However, in individuals with higher trait anxiety, downward counterfactual thinking was more effective than rehearsal for reducing regret, and it was as effective as distancing in reducing arousal. We discuss these results in light of the functional theory of counterfactual thinking and suggest that they motivate further investigation into downward counterfactual thinking as a means to intentionally regulate emotional memories in affective disorders.

In Canada, much media attention has recently been focused on the formation of arbitration tribunals that would use Islamic law or Sharia to settle civil matters in Ontario. In fact, the idea of private parties voluntarily agreeing to arbitration using religious principles or a foreign legal system is not new. Ontario's Arbitration Act has allowed parties to resolve disputes outside the traditional court system for some time. This issue has been complicated by the fact that Canada has a commitment to (...) upholding both a policy of multiculturalism and an international obligation towards women's rights. Although these values need not necessarily conflict, in this context, they have carried a tension that must be reconciled. This paper will examine the legal implications of faith-based arbitration tribunals in family law, with a particular emphasis on the impact that Sharia could have on Muslim women in Ontario.

In this paper I will consider whether there is something intelligible in finding value in having or aspiring to a certain kind of relationship which includes sex as a central feature. I argue that a scientific explanation can tell us only about the mechanics of sex, not what it feels like or means to us. Thus, we need to consider the meaning and significance of sex in relation to what we typically value about romantic love. I argue that sex is (...) partly constitutive of the central goods of romantic relationships, and can be an important vehicle for romantic love in two ways. It can express romantic love and it can ‘make love’, creating and intensifying it. This is because four of the central goods that we want from romantic love: 1) pleasure, (2) intimacy, (3) vulnerability and care and (4) union, can all be found in sex. Because of this, we seek romantic partners to whom we are sexually attracted and we are sexually attracted to people, in part, because they would make a good romantic partner to us. Nonetheless, this does not imply that a romantic relationship becomes less valuable the less sex it includes. (shrink)

This study aims to investigate the spillover impact of work-family/family–work conflict and stress on five major industrial sectors, during the first wave of Covid-19. The purpose of this cross-sectional study is twofold; firstly, to test a hypothesized model where work-family/family-work conflicts are related to stress and where stress could exert a mediating role in such relationships. Secondly, we seek to explore the presence of these conflicts and stress in each of the five major industrial sectors and evaluate if there are (...) significant differences between them, identifying the sociodemographic characteristics associated. Two questionnaires were applied to 748 employees from the selected industries. According to our results, stress predicts both types of conflict and also exerts a mediator role. It was primarily found that the five sectors are significantly different regarding the work-family/family-work conflicts and stress. Findings and implications are discussed. (shrink)

The definition of consumerism is multifaceted, extending from the consumption of goods and services to its more negative connotations: the obsessive consumption of goods, exploitation of the people who create them and greed. In a society heavily influenced by consumerism, we find ourselves manipulated by social media and targeted advertising to buy goods or to cultivate a certain lifestyle, raising important ethical questions about responsibility and our autonomy to make decisions. How has the nature of how we create and consume (...) goods evolved and how is this linked to moral responsibility and autonomy? Can it also be argued that there is aesthetic appreciation to be gained from some of the items that we create and consume? (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy's Role in Psychopathology Back to Jaspers and an Appeal to Grow PracticalThe author reports no conflicts of interest.In "Philosophy's role in theorizing psychopathology," Gibson presents a defense of the continued relevance of philosophy to psychopathology, and a non-exhaustive framework for the role of philosophy in this domain (Gibson, 2024). I find it hard to disagree that psychopathology is soaked in philosophy from its origins, and that to try (...) and dry it out would be both unwise and impossible.In this commentary, I go back to Karl Jaspers' account of the role of philosophy in his General Psychopathology. In doing so, I do not find that Gibson adds anything new, but instead gives us a well-illustrated reminder that philosophy "is operative within every living science" (Jaspers, 1997, p. 770).Situated Psychopathological TheorizingGibson addresses a broad 'we' who might be engaged with psychopathological theorizing. This seems to encompass three main settings, from which examples are drawn.1. Everyday and regulative social practices (ordinary and legal setting).2. Empirically driven disciplines which work with psychopathological constructs (academic setting).3. Psychiatry and psychotherapy (clinical setting).In my view, it is a mistake not to map the terrain where psychopathological theorizing is situated. In each setting psychopathological theorizing has its own set of aims and constraints. In the ordinary setting, the aim might be to know whether to blame a loved one for their action. In the legal setting it might be to decide whether treatment or punishment is appropriate. In the clinical setting, the aim is usually a therapeutic assessment, and moral stance taking is often best kept at bay. In the academic setting, we might want to ensure our concepts are reliable and valid, opening them up to investigation using objective scientific methods. [End Page 13]Beyond what can be said in the most general terms, the role of philosophy will look different in these different situations.Understanding Is Not (Just) a Philosophical ToolUnderstanding is a mode of knowing that is concerned with the particular, rather than the general, and accessed inter-relationally, relying on tacit knowledge and empathetic imagination. Gibson introduces the concept as an elementary form of social intuition, used in ordinary life to make sense of social relations and other people's behaviors and reactions. I agree with Gibson, drawing on Strawson, that Understanding is a mode of knowledge that involves the subject of enquiry as a participant (Strawson, 1982). There is a moral imperative to take this stance, which drives us to value the expansion of what we are able to understand of other people's mental states. This at least partly motivates the agenda when we theorize about psychopathology.At times throughout his argument, Gibson seems to be arguing for the role of Understanding in psychopathological theorizing, in place of his explicit aim of arguing for the role of philosophy. However it is not at all clear that this replacement can be made. Accepting the picture drawn, Understanding is not any more the expertise or domain of the philosopher than the author, police officer, or sociologist. We are surely not meant to take Understanding as a uniquely philosophical tool, but rather a mode of knowing available to all social agents, integral to social reasoning in ordinary life and in the human studies.What philosophy can distinctively do is point to and defend the existence of forms of intersubjective and tacit knowledge within human studies such as psychopathology. For Jaspers, Understanding can be a scientific tool, albeit one that reminds us that knowledge in psychopathology is not all of one kind. One role for philosophy therefore is to help us to "distinguish the different modes of knowing," so that we might "order knowledge into a comprehensive whole" (Jaspers, 1997, p. 769). This is akin to the 'synthetic' role that Gibson proposes.Philosophy and ScienceJaspers defines scientific knowledge broadly as knowledge with "general validity, convincing insights (which can be proved), clarity of method, and the possibility for a meaningful discussion" (Jaspers, 1997, p. 768).We do not get such a definition from Gibson, but in the sections of...

In a review of the cell biology and heredity studies of 1900–1910, Bernardino Fantini argues that the choice of an experimental subject or organism was crucial in opening up new discoveries and new theories for specific fields of research.69 Thinking on a broader level, Bütschli expressed a similar view when he stated that an understanding of the true nature and structure of the “elementary organism” was crucial to the whole of biology. In this article we have traced the impact of (...) Bütschli's unicellular model of protozoa up to the general acceptance of the eukaryotic cell as nature's primary organism. We have also seen that Bütschli's vision in the Studien gave birth to Protistenforschung and Zellforschung, sister sciences whose task it was to further and integrate knowledge of the living cell. Of necessity, we have confined ourselves to German scientific developments. However, our attempt to recapture and define the unity and meaning of a biology of the “cell-microcosm” has given us pause to reconsider the development and nature of Wilhelmian biological science.

Colleges and universities exist within a political arena where external demands for accountability materialize within a market-driven environment. As a result, government agencies pressure colleges and universities to rely on assessment and transparent reporting to become more market-driven assuming that the competition within the market, led by public choice and institutional selection, will drive improvements in learning and will also self-govern the institutions. This article explores how Foucault informs our conception of neoliberal governmentality through political rationality and technologies of self-governance (...) in order to inform our understanding of accountability in higher education and to challenge institutions to develop a counter dialogue which meets institutional obligations to the public and market.

Gender differences in children’s and adults’ time use are well documented, but few have examined the intervening period—young adulthood. Because many Americans navigate higher education in young adulthood, college time use provides insight into how gendered behaviors evolve during this critical life stage. Using three years of time use data from the National Longitudinal Survey of Freshmen and latent transition analysis, I examine gender differences in time use within and across the college years for those in selective institutions. Among students (...) whose time use is consistent throughout college, I find that women exhibit academically-oriented time use more often, and men exhibit socially oriented time use more often. However, many men transition from social time use at the beginning of college to academic time use toward the end—to the extent that gender gaps in academic time use converge by the third year. I argue that men and women construct distinct college pathways, and that men, in particular, must reroute their time use to accommodate gendered expectations for the transition to adulthood.

For many families, the idea of going out for walks and family adventures can be a dream that is erased by the determination of autistic spectrum in a child. Gaps in the health and quality of life of young people with autism spectrum disorder (ASD) are well documented. One particularly noticeable gap that affects both physical health and quality of life is in the area of outdoor recreation, particularly including outdoor recreation activities such as biking, hiking, running, canoeing/kayaking, horseback riding, (...) and skiing. Of the many outdoor activities to promote physical fitness, hiking is perhaps the most versatile and accessible for people with ASD. Hiking is a natural extension of walking. It is one of the first skills we acquire, one of the most important activities in everyday life and one of the few forms of recreation that does not require specific equipment and conditions. On the other hand, except for perhaps the most densely populated urban areas, there are almost always trails nearby. Lately even urban hikes that move around the city are becoming more and more popular. Whether you’re climbing the mountains at an expert level or hiking a trail, hiking gets your kids moving, which is of utmost importance in our modern society, when childhood seems to be filled more and more with time spent in front of the screens, and for children with autism this can become a serious problem. The main goal of this paper, on the one hand, is to increase awareness of the importance of hiking for psychophysical health, both for people from the general population and for people with ASD, but also to give recommendations for the approach and the way of organizing hiking activities for people with ASD, on the other hand.

The paper defends a view of structural realism similar to that of French and Ladyman, although it differs from theirs in an important respect: I do not take indistinguishabiity of particles in quantum mechanics to have the significance they think it has.

Adolescence is a time of transition from childhood to adulthood during which significant changes occur across multiple domains, including emotional experience. This article reviews the relevant literature on adolescents’ experience of four specific dimensions of emotion: emotional frequency, intensity, instability, and clarity. In an effort to examine how emotional experiences change as individuals approach adulthood, we examine these dimensions across ages 10 to 19, and review how the emotional functioning of adolescents compares to that of adults. In addition, we explore (...) whether and how gender and puberty explain age differences in emotional experience. Finally, we discuss how these findings could inform future research on both the typical trajectory of emotional experience and the development of psychopathology in adolescence. (shrink)

Previous work has shown that memory performance in older adults is affected by activation of a stereotype of age-related memory decline. In the present experiment, we examined whether stereotype threat would affect metamemory in older adults; that is, whether under stereotype threat they make poorer judgments about what they could remember. We tested older adults (MAge= 66.18 years) on a task in which participants viewed words paired with point values and “bet” on whether they could later recall each word. If (...) they bet on and recalled a word, they gained those points, but if they bet on and failed to recall a word, they lost those points. Thus, this task required participants to monitor how much they could remember and prioritize high value items. Participants performed this task over six lists of items either under stereotype threat about age-related memory decline or not under stereotype threat. Participants from both groups performed similarly on initial lists, but on later lists, participants under stereotype threat showed impaired performance as indicated by a lower average point score and a lower average gamma coefficient. The results suggest that a modest effect of stereotype threat on recall combined with a modest effect on metacognitive judgments to result in a performance deficit. This pattern of results may reflect an effect of stereotype threat on executive control reducing the ability to strategically use memory. (shrink)

Category Theory has developed rapidly. This book aims to present those ideas and methods which can now be effectively used by Mathe­ maticians working in a variety of other fields of Mathematical research. This occurs at several levels. On the first level, categories provide a convenient conceptual language, based on the notions of category, functor, natural transformation, contravariance, and functor category. These notions are presented, with appropriate examples, in Chapters I and II. Next comes the fundamental idea of an adjoint (...) pair of functors. This appears in many substantially equivalent forms: That of universal construction, that of direct and inverse limit, and that of pairs offunctors with a natural isomorphism between corresponding sets of arrows. All these forms, with their interrelations, are examined in Chapters III to V. The slogan is "Adjoint functors arise everywhere". Alternatively, the fundamental notion of category theory is that of a monoid -a set with a binary operation of multiplication which is associative and which has a unit; a category itself can be regarded as a sort of general­ ized monoid. Chapters VI and VII explore this notion and its generaliza­ tions. Its close connection to pairs of adjoint functors illuminates the ideas of universal algebra and culminates in Beck's theorem characterizing categories of algebras; on the other hand, categories with a monoidal structure lead inter alia to the study of more convenient categories of topological spaces.

In some cultures, people tend to believe that it is very important to be sexually exclusive in romantic relationships and idealise monogamous romantic relationships; but there is a tension in this ideal. Sex is generally considered to have value, and usually when we love someone we want to increase the amount of value in their lives, not restrict it without good reason. There is thus a call, not yet adequately responded to by philosophers, for greater clarity in the reasons §why (...) it might be reasonable for a couple to adopt a policy of sexual exclusivity. This article argues that we cannot justify the demand for sexual exclusivity by a need to protect the relationship from the risk of one partner ‘trading-up’, or by appealing to jealousy. However, sexual exclusivity can be intelligible if it supports the romantic relationship and helps to distinguish it from other relationships. Nonetheless, sexual exclusivity ought not to be the hegemonic social norm that it currently is in some societies because this diminishes the potential value it might have and gives the idea of faithfulness the wrong focus.
