Let equation image be the semigroup of all mappings on the natural numbers equation image, and let U and V be subsets of equation image. We write U≼V if there exists a countable subset C of equation image such that U is contained in the subsemigroup generated by V and C. We give several results about the structure of the preorder ≼. In particular, we show that a certain statement about this preorder is equivalent to the Continuum Hypothesis.The preorder ≼ (...) is analogous to one introduced by Bergman and Shelah on subgroups of the symmetric group on equation image. The results in this paper suggest that the preorder on subsemigroups of equation image is much more complicated than that on subgroups of the symmetric group. (shrink)

This two-volume set provides a comprehensive overview of the multidisciplinary field of Embodied Cognition. With contributions from internationally acknowledged researchers from a variety of fields, _Foundations of Embodied Cognition_ reveals how intelligent behaviour emerges from the interplay between brain, body and environment. Covering early research and emerging trends in embodied cognition, Volume 1 _Perceptual and Emotional Embodiment_ is divided into four distinct parts, bringing together a number of influential perspectives and new ideas. Part one opens the volume with an overview (...) of theoretical perspectives and the neural basis of embodiment, before part two considers body representation and its links with action. Part three examines how actions constrain perception of the environment, and part four explores how emotions can be shaped and structured by the body and its activity. Building on the idea that knowledge acquisition, retention and retrieval are intimately interconnected with sensory and motor processes, _Foundations of Embodied Cognition_ is a landmark publication in the field. It will be of great interest to researchers and advanced students from across the cognitive sciences, including those specialising in psychology, neuroscience, intelligent systems and robotics, philosophy, linguistics and anthropology.

Let ΩΩ be the semigroup of all mappings of a countably infinite set Ω. If U and V are subsemigroups of ΩΩ, then we write U≈V if there exists a finite subset F of ΩΩ such that the subsemigroup generated by U and F equals that generated by V and F. The relative rank of U in ΩΩ is the least cardinality of a subset A of ΩΩ such that the union of U and A generates ΩΩ. In this paper (...) we study the notions of relative rank and the equivalence ≈ for semigroups of endomorphisms of binary relations on Ω.The semigroups of endomorphisms of preorders, bipartite graphs, and tolerances on Ω are shown to lie in two equivalence classes under ≈. Moreover such semigroups have relative rank 0, 1, 2, or in ΩΩ where is the minimum cardinality of a dominating family for . We give examples of preorders, bipartite graphs, and tolerances on Ω where the relative ranks of their endomorphism semigroups in ΩΩ are 0, 1, 2, and .We show that the endomorphism semigroups of graphs, in general, fall into at least four classes under ≈ and that there exist graphs where the relative rank of the endomorphism semigroup is 20.

This two-volume set provides a comprehensive overview of the multidisciplinary field of Embodied Cognition. With contributions from internationally acknowledged researchers from a variety of fields, Foundations of Embodied Cognition reveals how intelligent behaviour emerges from the interplay between brain, body and environment. Drawing on the most recent theoretical and empirical findings in embodied cognition, Volume 2 _Conceptual and Interactive Embodiment_ is divided into four distinct parts, bringing together a number of influential perspectives and new ideas. Part one introduces the field (...) of embodied language processing, before part two presents recent developments in our understanding of embodied conceptual understanding. The final two parts look at the applied nature of embodied cognition, exploring the embodied nature of social co-ordination as well as the emerging field of artificial embodiment. Building on the idea that knowledge acquisition, retention and retrieval are intimately interconnected with sensory and motor processes, _Foundations of Embodied Cognition_ is a landmark publication in the field. It will be of great interest to researchers and advanced students from across the cognitive sciences, including those specialising in psychology, neuroscience, intelligent systems and robotics, philosophy, linguistics and anthropology.

Avec des textes de D. Armstrong, M.Esfeld, K. Fine, D. Lewis, H. Mellot, K. Mulligan, M. Rea, P. Unger, P. van Inwagen, D. Zimmerman. L’ontologie est la partie de la métaphysique qui traite de l’être en général, et non d’un être en particulier, et son domaine d’enquête excède même le monde actuel puisqu’elle porte sur l’ensemble du possible, sur les objets possibles et réels ainsi que sur leurs propriétés ou sur leurs structures ultimes. Ce volume fournit les textes fondamentaux pour (...) réfléchir aux principales notions de l’ontologie contemporaine. Y sont abordés les problèmes de la composition matérielle des objets, de la causalité, de la nature du temps et des relations en général. Les questions de méthode portent sur le lien avec la logique et les sciences tout autant que sur le recours aux catégories conceptuelles et aux intuitions. (shrink)

Mitochondrial replacement therapy (MRT), also called nuclear genome transfer and mitochondrial donation, is a new technique that can be used to prevent the transmission of mitochondrial DNA diseases. Apart from the United Kingdom, the first country to approve MRT in 2015, Australia became the second country with a clear regulatory path for the clinical applications of this technique in 2021. The rapidly evolving clinical landscape of MRT makes the elaboration and evaluation of the responsible use of this technology a pressing (...) matter. As jurisdictions with less strict or non-existent reproductive laws are continuing to use MRT in the clinical context, the need to address the underlying ethical issues surrounding MRT’s clinical translation is fundamental.

Verwijzend naar de Burndy Library conferentie in 1973 schrijft P.A. Kroes in de inleiding tot de ‘proceedings’ van de internationale conferentie over ‘Technische ontwikkeling en natuurwetenschap in de 19e en 20e eeuw’,1 dat tijdens de eerstgenoemde conferentie de meeste deelnemers van mening waren dat de opvatting van techniek als toegepaste wetenschap onjuist was. Technische produkten volgen niet zonder meer lineair uit de beschikbare natuurwetenschappelijke kennis. Een dergelijke zienswijze leidt bovendien snel tot de gedachte dat bij een autonome ontwikkeling van de (...) natuurwetenschap, ook de techniek zich autonoom zou ontwikkelen. Echter, Kroes moet concluderen, dat ondanks alle moeite die men zich sindsdien heeft gegeven om de verhouding tussen techniek en natuurwetenschap te bestuderen en nader te bepalen, hierin bijzonder weinig vooruitgang is geboekt.

My object in this paper is to suggest a few reflections on some themes in Bentham's work which others as well as I have noted, without perhaps developing them as fully as might with advantage be done. There will be nothing like full development in the limited compass of what is said here, but what is said may at least indicate possible directions for further exploration. The greater part of the paper will be concerned with the notion of natural authority; (...) but I want to begin by taking a broader, though no doubt rather superficial, view of the role in Bentham's thinking of the concepts of ‘nature’ and ‘the natural’.

The object of this article is to examine, with the work of Jeremy Bentham as the principal example, one strand in the complex pattern of European social theory during the second half of the eighteenth century. This was of course the period not only of the American and French revolutions, but of the culmination of the movements of thought constituting what we know as the Enlightenment. Like all great historical episodes, the Enlightenment was both the fulfilment of long-established processes and (...) the inauguration of new processes of which the fulfilment lay in the future. Thus the seminal ideas of seventeenth-century rationalism realized and perhaps exhausted their potentialities in the eighteenth-century Enlightenment. The ideas with which this article is concerned, however—conveniently grouped and labelled as the ideas of utilitarianism—only began to achieve systematic development in these later decades of the eighteenth century. Within that period—during the first half and more of Bentham's long life—attempts to apply those ideas to the solution of social problems met largely with failure and frustration. Yet unrealized potentialities remained, the realization of which was reserved for a time when the world of the philosophes no longer existed. The movements for social and political reform which have played so large a part in modern history since the French Revolution may be judged in widely differing ways; but whatever the verdict, these movements surely cannot be understood without due consideration of that part of their origins which lies in eighteenth-century utilitarianism.

The increased use of human biological material for cell-based research and clinical interventions poses risks to the privacy of patients and donors, including the possibility of re-identification of individuals from anonymized cell lines and associated genetic data. These risks will increase as technologies and databases used for re-identification become affordable and more sophisticated. Policies that require ongoing linkage of cell lines to donors’ clinical information for research and regulatory purposes, and existing practices that limit research participants’ ability to control what (...) is done with their genetic data, amplify the privacy concerns.

Like many people these days, I believe there is no general moral obligation to obey the law. I shall explain why there is no such moral obligation – and I shall clarify what I mean when I say there is no moral obligation to obey the law – as we proceed. But also like many people, I am unhappy with a position that would say there was no moral obligation to obey the law and then say no more about the (...) law's moral significance. In our thinking about law in a resonably just society, we have a strong inclination to invest law with a sort of moral halo. It does not feel right to suggest that law is a morally neutral social fact, nor to suggest that law is merely a useful social technique. In this essay, I shall try to account in part for law's moral halo. Because I share the widespread inclination to invest law with this halo, I shall not be interested in a merely historical account of how we come to see law with a halo – a pure “error theory” of law's halo, if you will. I want to justify the halo. On the other hand, the main way to justify the halo is to get clear just what law's moral significance is. It is unlikely that at the end of the process of clarification the halo will have exactly the shape or luminance that it had at the beginning. (shrink)

P. O. Bodunrin, in his 1981 essay, asks: ‘Is there an African Philosophy, and if there is, what is it?’ This question has occupied centre stage among younger African intellectuals for about a decade now. The most articulate among these intellectuals, who are themselves philosophers, are Bodunrin , Kwasi Wiredu , H. Odera Oruka , Marcien Towa and Eboussi Boulaga , and Paulin Hountondji . These philosophers among others are in dialogue with one another and currently are seen to be (...) the principal architects of a new orientation in African thought. (shrink)
