Symmetry considerations dominate modern fundamental physics, both in quantum theory and in relativity. Philosophers are now beginning to devote increasing attention to such issues as the significance of gauge symmetry, quantum particle identity in the light of permutation symmetry, how to make sense of parity violation, the role of symmetry breaking, the empirical status of symmetry principles, and so forth. These issues relate directly to traditional problems in the philosophy of science, including the status of the laws of nature, the (...) relationships between mathematics, physical theory, and the world, and the extent to which mathematics suggests new physics.This entry begins with a brief description of the historical roots and emergence of the concept of symmetry that is at work in modern science. It then turns to the application of this concept to physics, distinguishing between two different uses of symmetry: symmetry principles versus symmetry arguments. It mentions the different varieties of physical symmetries, outlining the ways in which they were introduced into physics. Then, stepping back from the details of the various symmetries, it makes some remarks of a general nature concerning the status and significance of symmetries in physics. (shrink)

: As Heidegger acknowledges, our understanding is essentially situated and so limited by the context and tradition into which it is thrown. But this ‘situatedness’ does not exhaust Heidegger's concept of ‘thrownness’. By examining this concept and its grammar, I develop a more complete interpretation. I identify several different kinds of finitude or limitation in our understanding, and touch on ways in which we confront and carry different dimensions of our past.

ABSTRACT:Psychedelics, including psilocybin, and other consciousness-altering compounds such as 3,4-methylenedioxymethamphetamine (MDMA), currently are being scientifically investigated for their potential therapeutic uses, with a primary focus on measurable outcomes: for example, alleviation of symptoms or increases in self-reported well-being. Accordingly, much recent discussion about the possible value of these substances has turned on estimates of the magnitude and duration of persisting positive effects in comparison to harms. However, many have described the value of a psychedelic experience with little or no reference (...) to such therapeutic benefits, instead seeming to find the experience valuable in its own right. How can we make sense of such testimony? Could a psychedelic experience be valuable even if there were no persisting beneficial effects? If so, how? Using the concept of psychological richness, combined with insights from the philosophy of aesthetics and the enhancement literature, this essay explores potential sources of value in the acute subjective experience, apart from the value derived from persisting beneficial effects.

Psychedelics such as psilocybin reliably produce significantly altered states of consciousness with a variety of subjectively experienced effects. These include certain changes to perception, cognition, and affect,1 which we refer to here as the acute subjective effects of psychedelics. In recent years, psychedelics such as psilocybin have also shown considerable promise as therapeutic agents when combined with talk therapy, for example, in the treatment of major depression or substance use disorder.2 However, it is currently unclear whether the aforementioned acute subjective (...) effects are necessary to bring about the observed therapeutic effects of psilocybin and other psychedelics. This uncertainty has sparked a lively—though still largely hypothetical—debate on whether psychedelics without subjective effects (“nonsubjective psychedelics” or “non-hallucinogenic psychedelics”) could still have the same therapeutic impact, or whether the acute subjective effects are in fact necessary for this impact to be fully realized.3,4,5.

Personal narratives can let us in on aspects of reality which we have not experienced for ourselves, and are thus important sources for philosophical reflection. Yet a venerable tradition in mainstream philosophy has little room for arguments which rely on personal narrative, on the grounds that narratives are particular and testimonial, whereas philosophical arguments should be systematic and transparent. I argue that narrative arguments are an important form of philosophical argument. Their testimonial aspects witness to novel facets of reality, but (...) their argumentative aspects help us to understand those facets for ourselves. My argument takes the form of a case study of the exemplary narrative argument penned by Rachel Moran, a former prostitute who uses her experiences to argue that prostitution amounts to sexual abuse. We’ll see that narrative arguments can enjoy expository Advantages over analytic ones. (shrink)

This article develops a model of informed consent for fresh oöcyte donation for stem cell research, during in vitro fertilisation (IVF), by building on the importance of patients’ embodied experience. Informed consent typically focuses on the disclosure of material information. Yet this approach does not incorporate the embodied knowledge that patients acquire through lived experience. Drawing on interview data from 35 patients and health professionals in an IVF clinic in Australia, our study demonstrates the uncertainty of IVF treatment, and the (...) tendency for patients to overestimate their chances of success prior to the experience of treatment. Once in active treatment, however, patients identify their oöcytes as both precious and precarious. We argue that it is necessary to formally include embodied experience as a source of knowledge in informed consent procedures, both for gratuitous donation and for egg-sharing regimes. We recommend that at least one full cycle of IVF be completed before approaching women to divert eggs away from their own fertility treatment. (shrink)

Student nurses’ professional development arises through socialisation in nursing knowledge, values and behaviours. Students are expected to demonstrate compassion; however, compassion is a complex concept, one that creates emotional challenges. A grounded theory study was undertaken to explore student nurse socialisation in compassionate practice. In-depth interviews were undertaken with 19 students in the north of England during 2009–2010, and their concerns and concern management emerged. Students expressed several concerns, one being their emotional vulnerability and uncertainty of the emotional requirements for (...) compassionate practice. A core category of ‘balancing future intentions’ was identified: that students managed feelings of vulnerability and uncertainty through balancing their intentions towards and away from engagement in compassionate practice, depending upon perceived impact on their emotional well-being. The findings are discussed in relation to emotional labour and moral distress, and courage, resilience and self-compassion are explored as a means to enable sustainable compassionate practice.

The narrative view of personhood suggests that we as persons are constituted by self-narratives. Self-narratives support not only the sense of personal persistence but also agency. However, it is rarely discussed how self-narratives promote or hinder personal well-being. This paper aims to explore what a healthy self-narrative looks like. By reframing a famous debate between Strawson and Schechtman about narrative personhood, I argue that self-narratives can hinder our personal well-being when affective identification leads to inflexible self-images, illustrated with the examples (...) of imposter syndrome and rationalization. Furthermore, I explore how having a healthy self-narrative is not about disengaging from one's personal past and future, but about fostering affective identification in ways that allow flexible self-images.

In this paper, I answer the question,how do we collaborate well with others?I first look at cases of good collaboration, contrasting them briefly with some cases of poor collaboration; I then describe the similarities between the good cases, such as shared aims, shared planning of projects, shared norms among collaborators. The conclusion is that collaborating well involves shared norms, derived both from societal norms and from a well‐ordered relationship between participants; a shared vision derived from shared knowledge and open communication (...) grounded in relationship; and open‐mindedness and thoughtful disagreement, which depend on mutual respect and trust between participants.

In the context of Ireland’s new legislation governing abortion, I outline and examine the spatial consequences of political decision-making. I argue that Ireland’s new abortion law and its clinical guidance permit travel for some pregnant people but impose fixity on others. I analyse the spatial consequences of legal limitations, including non-medically necessary delays in care and medical control of medication abortions, that necessitate travel for abortion. I demonstrate how current laws fix some pregnant people in place, including diverse migrant populations (...) within Ireland, with no possibilities for abortion-related travel. This critique of the ‘new’ law demonstrates the Irish state’s continued political and medical control of abortion. (shrink)

Several prominent debates in biology, such as those surrounding adaptationism, group selection, and punctuated equilibrium, have focused on disagreements about the relative importance of a cause in producing a phenomenon of interest. Some philosophers, such as John Beatty have expressed scepticism about the scientific value of engaging in these controversies, and Karen Kovaka has suggested that their value might be limited. In this paper, I challenge that scepticism by giving a novel analysis of relative significance controversies, showing that there are (...) three forms they can take. I argue that these controversies can have significant epistemic upshots, in that they help scientists form predictions about new instances of the phenomenon of interest. Finally, using two historical examples, I show how engaging in these controversies can improve our understanding of causal relationships. (shrink)

Wegen der Globalisierung und der Säkularisierung ist heute nicht mehr selbstverständlich davon auszugehen, dass die eigenen religiösen Überzeugungen richtig sind. Wie können Gläubige darauf reagieren? Eine nachvollziehbare Reaktion wäre zu versuchen, das eigene religiöse Glaubenssystem vor aller scheinbaren Konkurrenz zu schützen, indem man religiösen Dissens innerhalb oder außerhalb der Glaubensgemeinschaft unterbindet oder unterdrückt. Die Autorin argumentiert jedoch dafür, dass die Förderung von solchem Dissens die religiöse Erkenntnis eigentlich begünstigt und zwar selbst für diejenigen, die ihr eigenes religiöses Glaubenssystem möglichst bewahren (...) wollen.

Within philosophy of physics it is broadly accepted that presentism as an empirical hypothesis has been falsified by the development of special relativity. In this article, I identify and reject an assumption common to both presentists and advocates of the block universe and then offer an alternative version of presentism that does not begin from spatiotemporal structure, which is an empirical hypothesis, and which has yet to be falsified. While some features of familiar presentism are lost, a sufficient core remains (...) to warrant the label. (shrink)

This article scrutinizes the political thought of a twelfth-century Parisian master, Peter the Chanter , with reference to a theme that has been prominent recently in political philosophy. This is the idea that a just government ought to be free from every kind of arbitrary interference in the lives of those “governed,” that is, that no person ought to be governed according to another's unconstrained will.

One of the clearest signs that Psychology has impacted popular culture is the public’s familiarity with the Rorschach ink-blot test. An excellent example of the Rorschach in popular culture can be found in Watchmen, the comic/graphic novel written by Alan Moore and Dave Gibbons (1987). In the mid-20th century Psychology had an especially contentious relationship with comics; some psychologists were very anxious about the impact comics had on young people, whereas others wrote comics to subvert dominant norms about gender and (...) sexuality. Yet historians of Psychology have had almost nothing to say about this popular and critically acclaimed novel. We read Watchmen here for its narratives that most concern the history of Psychology. We focus on such themes as anti-psychiatry, sexual violence, homophobia, lesbian erasure and social psychological research on bystander intervention. We argue it is possible to align Psychology and comics more closely despite their sometimes contentious history. In doing so we demonstrate the active role of the public in the history of the Rorschach, and the public engagement of Psychology via comics, and also reveal what is possible when historians consider comics within their histories.

This is a paper, aimed at students, which sets out some issues regarding personal identity over time.

The ancient Greek philosopher and teacher Aristotle was the founder of the Lyceum, a school in Athens dedicated to the study of nature and philosophical inquiry for over a hundred years. In opposition to his own teacher, Plato, Aristotle developed a metaphysical and ethical theory based on the view that human beings are embodied creatures, not merely thinking things. In doing so, he clarified and expanded the concept of virtue, developing a theory of virtue that has impacted how we think (...) about mental states, states of wellbeing, and states of moral character. In Book II of his Nicomachean Ethics, Aristotle explains how we learn good (or bad) habits through experience, education, and training. Pleasure and pain provide starting points for us, because they help orient us toward the good, but eventually our primary motivation should be to do good because it is good. Excellent habits are those that cause us to react in neither excessive nor deficient ways to the things around us. Once we have the right motivation to do good because it is good, and once our habitual righteous action exemplifies our stable character, we are virtuous and thriving people. (shrink)

The ethics of treating the seriously and critically ill have not been static throughout the ages. Twentieth century medicine has inherited from the nineteenth century a science which places an inappropriate weight on diagnosis over prognosis and management, combined with a seventeenth century duty to prolong life. However other earlier ethical traditions, both Hippocratic and Christian, respected both the limitations of medicine and emphasised the importance of prognosis. This paper outlines some of the historical precedents for the treatment of the (...) critically ill, and also how the current paradigm limits clinical practice and causes ethical tensions. An understanding that other paradigms have been ethically acceptable in the past allows wider consideration and acceptance of alternatives for the future. However future alternatives will also have to address the role of technology, given its importance in this area of medicine. (shrink)

Abstract In this paper I suggest a way that an already promising view on ethical art criticism can account for the value of mediocre artworks which endorse morally commendable perspectives. In order for the view I call prescriptive ethicism to deal with such cases of critical ambivalence, it must take account of the interaction between moral content and form in art. Such interaction is seen in the way the aesthetic features of an artwork partly determine its moral value, or success (...) in providing ethical insight. I argue that if a work lacks the kind of moral value which is determined by the interaction between form and content, then we have little reason to engage with that work. When a work expresses an otherwise commendable moral attitude in a clumsy or trite manner, while it is clearly compromised aesthetically, it is also compromised ethically. For such a work forfeits the ability to reveal new aspects of ethical life. (shrink)

In defending Levinas’s ethical theory against Ricoeur’s objections in Oneself as Another, I make a two-fold argument in regard to heroic action and the ordinary ethical relation. First, I suggest a definition of the hero as she who does what is right—that is, what is ethically necessary or obligatory—even when it requires extreme sacrifice. Second, I argue that the development of virtuous character, out of which such heroic action comes, is dependent upon the asymmetrical relation between an alterior Other and (...) a self who is willing to sacrifice to do what is right. Re-orienting oneself toward the ethical relation is, itself, a sacrifice, requiring that one adopt a non-reciprocal, asymmetrical devotion to the Other. Thus, ethics, including both heroic and ordinary ethical behavior, ought not be founded on notions of friendship, symmetry, or mutuality, but rather on absolute difference, asymmetry, and self-sacrifice.

On August 29, 2006, the United States Court of Appeals for the District of Columbia Circuit held that an injured ERISA plan beneficiary need not be “made whole” by any injury-related recovery from a third party in order for her ERISA plan to assert subrogation or reimbursement rights if the plan's terms either 1) “unambiguously establish a plan priority” to any funds a beneficiary recovers from a third party, or 2) are reasonably interpreted to establish such a priority by an (...)

Dependency relationships within the cell cycle allow cells to arrest the cycle reversibly in response to agents or conditions that interfere with specific aspects of its normal progression. In addition, overlapping pathways exist which also arrest the cell cycle in response to DNA damage. Collectively, these control mechanisms have become known as checkpoints. Analysis of checkpoints is facilitated by the fact that dependency relationships within the cell cycle, such as the dependency of mitosis on the completion of DNA synthesis, and (...) the DNA damage checkpoint can be separated genetically. In fission yeast, Schizosaccharomyces pombe, the dependency of mitosis on prior completion of DNA synthesis is mediated through tyrosine‐15 phosphorylation of the ubiquitous mitotic regulator p34cdc2. In contrast, the arrest of mitosis caused by DNA damage acts through a separate mechanism that appears to be independent of tyrosine‐15 phosphorylation. Despite these distinct interactions with the mitotic machinery, the majority of fission yeast mutants that are deficient in mitotic arrest after DNA damage are also unable to respond to inhibition of DNA synthesis. In this essay we survey the current knowledge concerning feedback controls and checkpoints within fission yeast and relate this to information derived from other systems. (shrink)

In the 1920s and 30s, Heidegger developed three explicit readings of Plato’s Phaedrus. These readings emphasize different dimensions of Plato’s dialogue and, at times, seem even to contradict one another. Though Heidegger pursues quite different interpretations of the dialogue, he remains steadfast in praising this Platonic dialogue above all others. I argue that these explicit readings provide fertile ground for reconsidering Heidegger’s engagement with Plato and not just with Platonism. I further develop an argument that a fourth, implicit reading of (...) Phaedrus can be found in Heidegger’s own dialogical text from the late 1940s, “das abendländische Gespräch”. I suggest that it is in this conversational text, where Plato’s name is never once mentioned, that Heidegger manages his most authentic engagement with the Platonic dialogue and with Plato himself.

Between 1944 and 1954, Heidegger wrote five dialogues – or conversations – that stage philosophical discussions. I argue these texts develop a yet unacknowledged Heideggerian pedagogy of conversation. From the characters he conjures to the topics of their discussions, Heidegger underscores the importance of teaching and learning differently in each conversation and shapes his own pedagogical sensibility. Each text uniquely elaborates a particular element of his pedagogy, including the importance of attending to attunement, making mistakes, coming together in community, poetic (...) interpretation, and the dangers of conversational language itself. Only in reading the conversations together does Heidegger’s conversational pedagogy emerge. Above all, the teacher must resist assuming an authoritative role with her students; the Heideggerian teacher must learn to silently gesture toward the locale of the question-worthy by preserving its alterity.
