In 2008, researchers created human three-dimensional neural tissue – known as the pioneering work of “brain organoids.” In recent years, some researchers have transplanted human brain organoids into animal brains for applicational purposes. With these experiments have come many ethical concerns. It is thus an urgent task to clarify what is ethically permissible and impermissible in brain organoid research. This paper seeks (1) to sort out the ethical issues related to brain organoid research and application and (2) to propose future (...) directions for additional ethical consideration and policy debates in the field. Toward (1), this paper first outlines the current state of brain organoid research, and then briefly responds to previously raised related ethical concerns. Looking next at anticipated scientific developments in brain organoid research, we will discuss (i) ethical issues related to in vitro brain organoids, (ii) ethical issues raised when brain organoids form complexes or have relationships with other entities, and (iii) ethical issues of research ethics and governance. Finally, in pursuit of (2), we propose research policies that are mindful of the ethics of brain organoid research and application and also suggest the need for an international framework for research and application of brain organoids.

The aim of this paper is to examine the role of imagination in environmental ethics and introduce an imaginative dimension as an essential part of environmental ethics. Imagination constitutes a basic condition for ethical thinking and action. Matters of environmental ethics have revealed the indispensable role of imagination in ethics. I’ll advance an imagination-based environmental ethics by developing Hans Jonas’ ethical thought. From his viewpoint, various effects of our action on nature and future generations, generally out of our sight, have (...) become an ethical concern. This necessitates the exercise of imagination because we must “imagine” those distant effects to act in an environmentally responsible way. Jonas’ “heuristics of fear” is an imaginative approach necessary for responsible action. Further, I reinterpret the role of imagination as motivating our “will to know.” In conclusion, I suggest the importance of environmental education as cultivating ecological imagination from the standpoint of environmental ethics.

Hunting Down Social Darwinism addresses the manner in which free-market advocacy is often criticized as social Darwinism. It explores the term’s meaning and the reasons such criticisms prove to be misleading. Hayashi examines whether it is fair to describe nineteenth-century free-market advocates Spencer and Sumner as social Darwinists.

This paper focuses on a water management project in the remote Aboriginal community of Milingimbi, Northern Australia. Drawing on materials and experiences from two distinct stages of this project, we revisit a policy report and engage in ethnographic storytelling in order to highlight a series of sensing practices associated with water management. In the former, a working symmetry between Yolngu and Western water knowledges is actively sought through the practices of the project. However, in the latter, recurrent asymmetries in the (...) research work continue to appear: a bilingual diagram of water usage is displayed but produces confusion; measuring a water hole for salinity, a member of the scientific team throws in a water meter, while a Yolngu elder prefers the telling of an ancestral story; a collaborative 3-D mapping exercise invites participation from community members but struggles to develop an outcome that differs from existing maps used by scientists and government staff. Focusing on these moments as subtle points of rupture, we suggest that attending to “seeing,” “telling,” and “mapping” in both stages of this water management project offers a way to explore the political work of crafting climate futures and beginning to interrogate differing means for “doing difference” within them.

We explore how adding prosocial preferences to the canonical precaution model of accidents changes either the efficient damages rule or the harm from accidents. For a utilitarian lawmaker, making the potential injurer sympathetic to the victim of harm has no effect on either outcome. On the other hand, making injurers averse to harming others reduces the harm from accidents but has no effect on efficient damages. For an atomistic lawmaker — one who excludes prosocial preferences from social welfare — cultivating (...) a taste for either harm aversion or perfect sympathy can reduce efficient damages, though neither has any effect on the amount of harm from accidents. On the other hand, causing people to act as if they are averse to harm creation, such as out of habit or moral obligation, reduces both the efficient amount of damages and total harm. In general, encouraging either a distaste for, or moral commitment against, harm creation is useful while inculcating sympathy for victims of harm is not. (shrink)

In the context of the controversies surrounding »globalisation« and In the context of the controversies surrounding »globalisation« and »multiculturality« the comparative study of cultures has the task of aiding intercultural communication and of contributing to the success of intercultural understanding. The model of contrastive cultural comparison discussed here is claimed to have applacibility to every possible study of other countries (»Auslandswissenschaft«) and to be able to provide the Geisteswissenschaften with an intercultural orientation.

In a dynamic environment, even if an agent makes a plan to obtain a goal, the environment might change while the agent is executing the plan. In that case, the plan, which was initially valid when it was made, might later become invalid. Furthermore, in the process of replanning, it is necessary to take into account the side effects of actions already executed. Nowadays, HTN planning is becoming popular among agent researchers because its task decomposition algorithm is efficient and suitable (...) for joint planning in multi-agent systems. However, the dynamic replanning algorithm of HTN planning has not yet been established. In order to solve this problem, we have previously presented an agent life cycle that integrates HTN planning, action execution, knowledge updates, and plan modification. In that agent life cycle, the plans are always kept valid according to the most recent knowledge and situation. However, when one plan does not work and the agent starts using an alternative plan, it sometimes undoes some actions that do not have to be undone. The source of this problem lies in the need to have total-order plans. In other words, all the actions have to be sequentially ordered even when the order is not important in some parts of the plan. This paper extends our previous agent life cycle and presents new ways to avoid unnecessary action cancellation. This enables the agent to handle partial-order plans and to make use of two kinds of undoing actions: sequential undoing actions and concurrent undoing actions. (shrink)

The Nature of Liberty trilogy presents an ethical case for individual liberty, arguing from the philosophy of Ayn Rand and citing the findings of evolutionary psychology to demonstrate the compatibility between human nature and laissez-faire liberty. The first installment, The Freedom of Peaceful Action, makes the philosophic case that an approach starting from observational reason will indicate the practicality and ethical desirability of a free-market system based on rights.

The doctrine of radical impermanence expresses the temporal dimension of Buddhist metaphysics, especially in the philosophy of Dharmakīrti and his successors. Most straightforwardly, the doctrine says that everything that exists is momentary; we are not impermanent in the sense that we perish eventually, say when our brain ceases functioning, but rather we perish immediately upon conception. The person who begins to write this sentence and the person who completes it are, strictly speaking, different entities. However, there is a devastating problem (...) for the doctrine: How can any momentary entities be causally efficacious, and more particularly, given their extremely meager duration of existence, how might the momentarist explain the phenomena of cooperation among contemporaneous entities to occasion novel entities, such as seeds, soil, water and sunlight giving rise to sprouts? Even more difficult, can the momentarist offer such an explanation that does not undermine his negative claim that non-momentary things cannot exist? Śāntarakṣita and Ratnakīrti offer answers, but they both fail. By meticulously analyzing and evaluating their arguments, I identify the stumbling blocks of their arguments and show what needs to be done to save the doctrine of momentariness. (shrink)

According to the Buddhist doctrine of Two Truths, there are no persons in our final ontology, but there are persons in our conventional ontology. What does it mean to say that persons exist conventionally? The Ābhidharmikas say that ultimately there are psychophysical tropes, called dharmas, certain collections or combinations of which are conventionally taken to be persons. We would then ask: what kind of reality is conventional reality, and what is the metaphysical relation between conventional reality and ultimate reality as (...) pertains to persons?Recently there have been various attempts to understand Buddhist philosophy by using contemporary analytical methods and theories. Among the prominent scholars in this... (shrink)

The so-called Buddhist momentarists, such as Dharmakīrti and his followers, defend the momentariness of all things. However, with equal force they also defend the persistence of all things, not just within a single lifetime but over an indefinite cycle of rebirth. Naturally, they have an interesting theory of persistence, according to which things persist without being self-identical over time. The theory is best presented in the Lokāyatāparīkṣā chapter of Śāntarakṣita’s Tattvasaṃgraha and Kamalaśīla’s Paṅjikā, as they clearly articulate the criteria of (...) persistence without identity. The purpose of this paper is to formulate a Buddhist theory of persistence through the analysis of these texts. Here is the basic formula: Things persist as series, which is constituted by momentary entities that are causally related as upādāna and upādeya. Upādāna causal relation is demarcated from other causal relations by the principle of changeability with temporal restriction, and the principle adopts further qualifications to accommodate complex cases and personal persistence. I have addressed a problem that contemporary physicalism might pose a threat to the Buddhist account of personal persistence, and argued that the problem can be evaded by regarding persons as psycho-physical entities rather than strictly non-physical. In its general outlook, the Buddhist theory of persistence is close to Theodore Sider’s stage theory in that persistence is a matter of distinct individuals standing in a special causal relationship. As regards personal persistence, the Buddhist has a stricter condition than Parfit’s IDM thesis, which states that psychological connectedness with any cause is what matters for survival. The Buddhist would say it is moral connectedness with a special cause called upādāna. (shrink)

“Atsumori” is a Noh play composed by master playwright Zeami sometime before 1423, featuring characters from the Tales of the Heike. Although popular to this day, the philosophical significance of the play remains underdeveloped and underappreciated. Prima facie, it features a ghost who is liberated thanks to the sincere prayer of the priest who killed him. Simplistic reading would yield simplistic understanding of the characters and their dynamism, and would fail to appreciate, for instance, the agency of the ghost or (...) the liberation of the priest. Accordingly, some regard the play as falling short of the highest aesthetic value, insofar as its protagonist fails to attain liberation through his own effort. Some even contend that the ulterior purpose of the play is to portray ghosts as powerless and desperate so that vanquishers need not fear vengeful ghosts. While it is possible that Zeami indeed held such ulterior intention and regarded it as second rank for the protagonist’s lack of agency, I shall present a different reading that would yield a richer appreciation of the characters and their dynamism. I do so by regarding the “friendship of dharma” that occurs at the culmination of the play as “existential communion” as presented in Tanabe Hajime’s later philosophy. That is, the play need not be read as a story about a living priest saving a dead warrior—it can be read as about two lost souls saving each other, through mutual acceptance, mutual sacrifice, and collaborative mediation of the Absolute. For this purpose, the paper first delineates Tanabe’s later philosophy with a focus on the idea of existential communion. Then it introduces “Atsumori” and discusses its philosophical significance. An impasse due to the scope of the play will be identified, which I call “the problem of epistemic authority,” and to fill the gap I will introduce and discuss another spin-off story featuring Atsumori. The paper intends to offer a philosophically richer reading of the play to invite readers to think deeply and creatively about Noh. (shrink)

This article proposes a methodological schema for engaging in a productive discussion of ethical issues regarding human brain organoids, which are three-dimensional cortical neural tissues created using human pluripotent stem cells. Although moral consideration of HBOs significantly involves the possibility that they have consciousness, there is no widely accepted procedure to determine whether HBOs are conscious. Given that this is the case, it has been argued that we should adopt a precautionary principle about consciousness according to which, if we are (...) not certain whether HBOs have consciousness—and where treating HBOs as not having consciousness may cause harm to them—we should proceed as if they do have consciousness. This article emphasizes a methodological advantage of adopting the precautionary principle: it enables us to sidestep the question of whether HBOs have consciousness and, instead, directly address the question of what kinds of conscious experiences HBOs can have, where the what-kind-question is more tractable than the whether-question. By addressing the what-kind-question, we will be able to examine how much moral consideration HBOs deserve. With this in mind, this article confronts the what-kind-question with the assistance of experimental studies of consciousness and suggests an ethical framework which supports restricting the creation and use of HBOs in bioscience.

As is mentioned in Leigh :845-865, 2015), it is an open problem whether for several axiomatic theories of truth, including Friedman–Sheard theory \ and Kripke–Feferman theory \ :690-716, 1976), there exist cut-elimination arguments that give the upper bounds of their proof-theoretic strengths. In this paper, we give complete cut-elimination results for several well-known axiomatic theories of truth. In particular, we treat the systems \, and \ \\) of Friedman and Sheard’s theories and \.

Si la question de la science divine dans le catholicisme et le protestantisme réformé n’a cessé d’attirer l’attention des historiens de la philosophie, la position de l’orthodoxie luthérienne est restée relativement méconnue. Or, le Systema Locorum Theologicorum d’Abraham Calov, professeur à Wittenberg, connu également comme Schulphilosoph, se distingue par sa profondeur et sa finesse parmi les ouvrages luthériens. Cet article étudie systématiquement son traitement de l’omniscience divine afin de mettre en évidence le caractère polémique attribué à cette notion. En situant (...) le texte dans le contexte historique et doctrinal de l’époque, on tâchera d’éclairer les problématiques principales du théologien vers la moitié de l’âge classique, ainsi que sa position vis-à-vis de certains auteurs majeurs.

In Western countries, the ideal professional and ethical attributes of healthcare providers and the ideal patient-doctor relationship have been analysed in detail. Other cultures, however, may have different norms, arising in response to diverse healthcare needs, cultural values and offering alternative perspectives. In this paper, drawing a case study, we introduce the concept of Shinmi, used in Japan to describe a desirable approach to medical care. Shinmi means kind or cordial in Japanese. In the medical context, it refers to doctors (...) treating patients with a degree of emotional closeness as if they were the doctors’ own family. We analyse the concept of Shinmi, drawing on virtue ethics. We distinguish two different elements to a Shinmi-na attitude. As illustrated in our example, excessive Shinmi can be problematic for patients and doctors. Furthermore, elements of Shinmi may conflict with existing Western values (for example, norms that encourage emotional detachment and discourage doctors’ treatment of family members). However, if pursued appropriately, we argue that a balanced Shinmi-na approach can be conducive to the goals of medicine. The concept of Shinmi may be valuable for medical students, in Japanese and potentially other health care systems, and help them to cultivate a virtuous approach to meeting the emotional needs of patients.
