Purpose: Yerkish is an artificial language created in 1971 for the specific purpose of exploring the linguistic potential of nonhuman primates. The aim of this paper is to remind the research community of some important issues and concepts related to Yerkish that seem to have been forgotten or appear to be distorted. These are, particularly, its success, its promising aspects for future research and last but not least that it was Ernst von Glasersfeld who invented Yerkish: he coined the term (...) “lexigrams,” created the first 120 of them and designed the grammar that regulated their combination. Design: The first part of this paper begins with a short outline of the context in which the Yerkish language originated: the original LANA project. It continues by presenting the language itself in more detail: first, its design, focusing on its “lexigrams” and its “correlational” grammar, and then its use by the chimpanzee Lana in formulating sentences. The second part gives a brief introduction to the foundation of Yerkish in Silvio Ceccato’s Operational Methodology, particularly his idea of the correlational structure of thought and concludes with the main insights that can be derived from the Yerkish experiment seen in the light of Operational Methodology. Findings: Lana’s success in language learning and the success of Yerkish during the past decades are probably due to the characteristics of Yerkish, particularly its foundation in operational methodology. The operation of correlation could be what constitutes thinking in a chimpanzee and an attentional system could be what delivers the mental content that correlation assembles into triads and networks. Research implications: Since no other assessment or explanation of Lana’s performances has considered these foundational issues, a new research project or program should validate the above-mentioned hypotheses, particularly the correlational structure of chimpanzee thinking.

Open peer commentary on the target article “Arguments Opposing the Radicalism of Radical Constructivism” by Gernot Saalmann. First paragraph: I appreciate Saalmann’s recognition that “there are considerable differences amongst the authors” and that these “have changed their opinions in the course of time” (§3); but given this, what are the consequences for an outline of the theses of radical constructivism (RC)? Which approach is best for outlining a theory of knowing under these hindering conditions? My suggestion would be to use (...) a method specifically developed for this kind of situation and to present it explicitly, or, if it does not yet exist, to develop one. (shrink)

Open peer commentary on the target article “Who Conceives of Society?” by Ernst von Glasersfeld. First paragraph: Issues such as social interaction and communication play an essential role in my recent approach to knowledge management called “Knowledge Cooperation”, conceived as “the participative cultivation of knowledge in a voluntary, informal social group”. Radical Constructivism provides a substantial support to the foundations of this approach, which aims at equilibrating intellectual and social capital. So I warmly welcome Ernst von Glasersfeld’s clarification of the (...) constructivist position in regard to “society.”. (shrink)

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: Avoiding the term “representation” would make the article much more consistent with a radical constructivist way of thinking. It would also open up unexpected opportunities for realizing the potential of some of its most interesting ideas, such as the connection between anticipatory drive and attention (§31).

Open peer commentary on the article “Constructivism and Computation: Can Computer-Based Modeling Add to the Case for Constructivism?” by Manfred Füllsack. Upshot: Füllsack’s article offers many interesting ideas but falls short of elucidating the relationship between constructivism and computation. It could profit by taking into consideration stronger constructivist foundations such as the distinction between machine and organism, the relationship between reality and the observer, and Ceccato’s theory of attention.

In the past, the European social sciences labelled and discredited knowledge that did not follow the definition for scientific knowledge as applied by the European social sciences as an alternative concept of knowledge, as “indigenous” knowledge. Perception has changed with time: Not only has indigenous knowledge become an entrance ticket to the European social science world, but the indigenization of European theories is seen by some as the contribution of “peripheral” social sciences to join the theories of the “centers”. This (...) book offers contributions to the discourses about alternative concepts of knowledge, inviting the reader to decide if they are alternative, indigenous, or European types of knowledge. However, in order to make this decision, the reader must know what the nature of the European concepts of science and of scientific knowledge is; this might be a motivation to read a book that presents thoughts claiming to be alternative concepts of knowledge, alternative to the European concept of science.

During the coronavirus pandemic, communities have faced shortages of important healthcare resources such as COVID-19 vaccines, medical staff, ICU beds and ventilators. Public health officials in the U.S. have had to make decisions about two major issues: which infected patients should be treated first (triage), and which people who are at risk of infection should be inoculated first (vaccine distribution). Following Beauchamp and Childress’s principlism, adopted guidelines have tended to value both whole lives (survival to discharge) and life-years (survival for (...) years past discharge). This process of collective moral reasoning has revealed our common commitment to both Kantian and utilitarian principles. For Kant, respecting people’s rights entails that we ought to value whole lives equally. Therefore we ought to allocate resources so as to maximise the number of patients who survive to discharge. By contrast, the principle of utility has us maximise life-years so that people can satisfy more of their considered preferences. Although people are treated impartially in the utilitarian calculus, it does not recognise their equal worth. Subjecting Kantian ethics and utilitarianism to the process of reflective equilibrium lends support to the idea that we need a pluralistic approach that would accommodate our moral intuitions regarding both the equal value of whole lives and the additive value of life-years.

Physicians have an ethical responsibility to their patients to offer the best available medical care. This responsibility conflicts with their role as gatekeepers of the limited health care resources available for all patients collectively. It is ethically untenable to expect doctors to face this trade-off during each patient encounter; the physician cannot be expected to compromise the wellbeing of the patient in the office in favour of anonymous patients elsewhere. Hence, as in other domains of public policy where individual and (...) collective interests conflict, some form of collective solution is required. Collective solutions may take the form of placing explicit resource constraints on resources available to physicians, or clinical practice guidelines that recognise cost-effective care as acceptable. Such solutions will be politically and ethically sustainable only if patients as citizens of the larger population accept the need for rationing of limited resources in health care. (shrink)

Mechanistic explanation involves the attribution of functions to both mechanisms and their component parts, and function attribution plays a central role in the individuation of mechanisms. Our aim in this paper is to investigate the impact of a perspectival view of function attribution for the broader mechanist project, and specifically for realism about mechanistic hierarchies. We argue that, contrary to the claims of function perspectivalists such as Craver, one cannot endorse both function perspectivalism and mechanistic hierarchy realism: if functions are (...) perspectival, then so are the levels of a mechanistic hierarchy. We illustrate this argument with an example from recent neuroscience, where the mechanism responsible for the phenomenon of ephaptic coupling cross-cuts the more familiar mechanism for synaptic firing. Finally, we consider what kind of structure there is left to be realist about for the function perspectivalist. (shrink)

The Gesta Normannorum Ducum is one of the most important sources for the history of Normandy and England in the eleventh and twelfth centuries, and contains the earliest prose account of the Norman Conquest. It was written by a succession of authors, the first of whom was William of Jumieges, who wrote for William the Conqueror. Later historians, such as Orderic Vitalis and Robert of Torigni, interpolated and extended the chronicle as far as King Henry I. The later accretions reveal (...) much not only about changing attitudes towards the Norman invasion of England, but also about views of the early Viking foundations of Normandy.Elisabeth van Houts's two-volume edition is based on a study of all forty-seven extant manuscripts of the Gesta, including the earliest surviving copy of c. 1100, unknown until very recently. The full original text of William of Jumieges is supplied, as well as the integral text of the subsequent revisions and additions. Volume I contains Dr van Houts's introduction to the whole work, together with the text and translation of books i-iv. Volume II contains books v-viii. The edition forms an important contribution to our understanding of Anglo-Norman politics. (shrink)

Objects: With the advent of genetic technologies, many genetic/metabolic disorders can be detected asymptomatically but might be untreatable, and the benefits and risks of screening for them are not fully known. The purpose of this study is to explore current practice with regard to the parental consent process in newborn screening .Design: Staff in 23 obstetric clinics/hospitals that conduct NBS in one city of southern Taiwan were interviewed. Using content analysis, 15 interview transcripts, eight completed questionnaires, and other relevant documents (...) from the 23 clinics/hospitals were analysed to reveal the framework of the parental consent process in NBS in southern Taiwan.Main measures: Three categories—informed consent, informed dissent, and no informed/consent—were developed to analyse the parental consent process in NBS.Results: The parental consent procedures in NBS and the quality of the information provided before obtaining consent vary widely. Because the traditional NBS was incorporated into routine paediatric practices in most clinics/hospitals, the most frequently encountered consent model is “informed dissent” and “no informed/consent” ; while an “informed consent” model is the frequent model for screening rare metabolic/genetic disorders.Conclusions: Specific guidelines to regulate the parental consent process for NBS are essential. Further studies should investigate parental responses to NBS, taking these as the basis on which to establish an informed consent model in Taiwan. (shrink)

This paper aims to outline the ethical concerns regarding the use of antidepressant medication in children and adolescents. Recent debates surrounding this issue have focused on the link between selective serotonin reuptake inhibitor use and an increased risk of suicidal thinking/behaviour, and weighed that against the benefit of the alleviation of depressive symptoms. It is argued here that such an approach is simplistic. There are several serious risks surrounding antidepressant use in the young that ought to be included in the (...) equation, along with a consideration of the neuroethical concerns surrounding pharmacotherapy for affective disorders. Using the precautionary principle as a framework for analysis it is concluded that the risks are sufficiently serious and plausible that the prescribing of antidepressant medication to the young ought to be severely restricted; further it is imperative that the child and their parents are made fully aware of the risks, short-term and long-term, involved.

The requirement of gauge invariance for the Schwinger-DeWitt equations, interpreted as a manifestly covariant quantum theory for the evolution of a system in spacetime, implies the existence of a five-dimensional pre-Maxwell field on the manifold of spacetime and “proper time” τ. The Maxwell theory is contained in this theory; integration of the field equations over τ restores the Maxwell equations with the usual interpretation of the sources. Following Schwinger's techniques, we study the Green's functions for the five-dimensional hyperbolic field equations (...) for both signatures ± [corresponding to O(4, 1) or O(3, 2) symmetry of the field equations] of the proper time derivative. The classification of the Green's functions follows that of the four-dimensional theory for “massive” fields, for which the “mass” squared may be positive or negative, respectively. The Green's functions for the five-dimensional field are then given by the Fourier transform over the “mass” parameter. We derive the Green's functions corresponding to the principal part ΔP and the homogeneous function Δ 1 ; all of the Green's functions can be expressed in terms of these, as for the usual field equations with definite mass. In the O(3, 2) case, the principal part function has support for x2⩾τ2, corresponding to spacelike propagation, as well as along the light cone x2=0 (for τ=0). There can be no transmission ofinformation in spacelike directions, with this propagator, since the Maxwell field, obtained by integration over τ, does not contain this component of the support. Measurements are characterized by such an integration. The spacelike field therefore can dynamically establish spacelike correlations. (shrink)

Within contemporary epistemology, notions of intellectual virtue have come to fulfill a prominent role in attempts to provide an account of knowledge. Notions of such virtue can vary, and one particular aspect of this variance concerns how to construe the relationship between the intellectual virtues and particular epistemic ends. The goal of this article is to defend an instrumental connection between the intellectual virtues and the epistemic end of true belief. One type of skeptical argument that attempts to sever this (...) connection, a Cartesian Demon argument, is considered. This Cartesian Demon argument will be summarized, as well as three responses to it. The claim that truth-conduciveness is a tenable criterion for identifying the intellectual virtues is then defended. It is acknowledged that the possibility of a Cartesian Demon does initiate scepticism, but that this scepticism is directed toward identifying specific intellectual virtues and not toward the instrumental connection between intellectual virtue and true belief.

If the a priori is the proper subject matter of transcendental philosophy, then the problems of the a priori are also problems for transcendental philosophy. the idea that defines transcendental philosophy is the idea that there are stable general structures which are discernible in experience, provide the foundations of our knowledge of it, and collectively constitute an a priori which transcends experience and informs it. the a priori is traditionally conceived as a nexus of relations which is held to be (...) logically/temporally prior to experience and responsible for its organization. in this essay, i challenge this traditional (kantian) understanding of the a priori and set forth an alternative to it based on the writings of maurice merleau-ponty. the intent is to provide a new conception of transcendental philosophy.

Because of cultural differences between East and West, any attempt at outright adaptation of Western ideas in Asia will undoubtly encounter problems, if not rejection. Transferring an idea from one place to another is just like transplanting an organ from a donor to a recipient—rejection is to be expected. Human cultures respond to new ideas from different value systems in very much the same way.Recently, biomedical ethics has received much attention in Asia. Fundamental advances in medicine have motivated medical scientists (...) to look at the ethical issues arising from this progress. Will the principles upheld by the bioethicists in the West meet the challenge in Asia? This article argues that Asian bioethicists must develop a bioethics responding to their own cultural contexts. If Western principles are adopted, then they must be re-interpreted and even modified, if necessary, in light of Asian beliefs. (shrink)
