Seventeen scholars have contributed to this Festschrift presented to Eugen Fink, Professor of Philosophy at the University of Freiburg/br., on the occasion of his sixtieth birthday. The essays are not intended to be "exemplary," but rather to express a community of thought; a participation of philosophers in the common task of defining significant problems for their discipline. A considerable number of the essays are thematically oriented around the works of Plato; the problems arising from his dialogues are approached from epistemological, (...) ontological and hermeneutic standpoints. Other topics include: the phenomenology of the human body viewed in its relation to the general concept of matter, pedagogics as a concern of the humanistic scholar in the light of Wilhelm Dilthey's philosophy and its continuation in his pupils, power viewed as a phenomenon, the dramas of Georg Büchner, philosophy East and West and the relation of history to tradition. A bibliography of the works of Eugen Fink and of books and essays on his works is also appended.—R. P. J. (shrink)

Interactive technology assessment (iTA) provides an answer to the ethical problem of normative bias in evaluation research. This normative bias develops when relevant perspectives on the evaluand (the thing being evaluated) are neglected. In iTA this bias is overcome by incorporating different perspectives into the assessment. As a consequence, justification of decisions based on the assessment is provided by stakeholders having achieved agreement. In this article, agreement is identified with wide reflective equilibrium to show that it indeed has the potential (...) of justifying decisions. We work out several conditions for this agreement to be achievable and just. (shrink)

Health care professionals often face moral dilemmas. Not dealing constructively with moral dilemmas can cause moral distress and can negatively affect the quality of care. Little research has been documented with methodologies meant to support professionals in care for the homeless in dealing with their dilemmas. Moral case deliberation is a method for systematic reflection on moral dilemmas and is increasingly being used as ethics support for professionals in various health-care domains. This study deals with the question: What is the (...) contribution of MCD in helping professionals in an institution for care for the homeless to deal with their moral dilemmas? A mixed-methods responsive evaluation design was used to answer the research question. Five teams of professionals from a Dutch care institution for the homeless participated in MCD three times. Professionals in care for the homeless value MCD positively. They report that MCD helped them to identify the moral dilemma/question, and that they learned from other people’s perspectives while reflecting and deliberating on the values at stake in the dilemma or moral question. They became aware of the moral dimension of moral dilemmas, of related norms and values, of other perspectives, and learned to formulate a moral standpoint. Some experienced the influence of MCD in the way they dealt with moral dilemmas in daily practice. Half of the professionals expect MCD will influence the way they deal with moral dilemmas in the future. Most of them were in favour of further implementation of MCD in their organization. (shrink)

The Covid-19 pandemic has resulted in disruption of work and other social activities of so many people. Some were forced to stay at home and many decided to stay at home for fear of being infected with the virus. This phenomenon brought different reactions and even mental stress to many people. However, there were people who turned this kind of tragedy into creative work. This paper discusses the experiences and insights of known plant lovers in Digos City, Davao del Sur (...) Philippines. Digos City is one of the heavily affected places during the series of earthquakes that jolted Davao del Sur last year. While people are still recovering, COVID-19 added an additional burden to the residents. In this paper, we argue that their decision to focus on gardening was not only to fight boredom and to divert their attention during lockdown but this was their way of maintaining their well-being by participating in the on-going work of creation and recreation and to rise from the tragedy. We further argue that it might be good that this creative work will go beyond home gardening and beyond pots and slowly extend to creative work for environmental protection and preservation through more active engagements into reforestation activities.

Layers of complexity arise when a person arrives in an Intensive Care Unit (ICU) due to self-harm intended to end their life and when there is known past personal trauma. We highlight three importa...

Human societies are extraordinarily cooperative compared to those of most other animals. In the vast majority of species, individuals live solitary lives, meeting to only to mate and, sometimes, raise their young. In social species, cooperation is limited to relatives and (maybe) small groups of reciprocators. After a brief period of maternal support, individuals acquire virtually all of the food that they eat. There is little division of labor, no trade, and no large scale conflict. Communication is limited to a (...) small repertoire of self-verifying signals. No one cares for the sick, or feeds the hungry or disabled. The strong take from the weak without fear of sanctions by third parties. Amend Hobbes to account for nepotism, and his picture of the state of nature is not so far off for most other animals. In contrast, people in even the simplest human societies regularly cooperate with many unrelated individuals. Human language allows low-cost honest communication of virtually unlimited complexity. The sick are cared for, and sharing leads to substantial flows of food from the middle aged to the young and old. Division of labor and trade are prominent features of every historically known human society, and archaeology indicates that they have a long history. Violent conflict among sizable groups is common. In every human society, social life is regulated by commonly held moral systems that specify the rights and duties of individuals enforced, albeit imperfectly, by third party sanctions. (shrink)

Human migration is nonrandom. In small scale societies of the past, and in the modern world, people tend to move to wealthier, safer, and more just societies from poorer, more violent, less just societies. If immigrants are assimilated, such nonrandom migration can increase the occurrence of culturally transmitted beliefs, values, and institutions that cause societies to be attractive to immigrants. Here we describe and analyze a simple model of this process. This model suggests that long run outcomes depend on the (...) relative strength of migration and local adaptation. When local adaption is strong enough to preserve cultural variation among groups, cultural variants that make societies attractive always predominate, but never drive alternative variants to extinction. When migration predominates, outcomes depend both on the relative attractiveness of alternative variants and on the initial sizes of societies that provide and receive immigrants. (shrink)

We present a full completeness theorem for the multiplicative fragment of a variant of noncommutative linear logic, Yetter's cyclic linear logic (CyLL). The semantics is obtained by interpreting proofs as dinatural transformations on a category of topological vector spaces, these transformations being equivariant under certain actions of a noncocommutative Hopf algebra called the shuffie algebra. Multiplicative sequents are assigned a vector space of such dinaturals, and we show that this space has as a basis the denotations of cut-free proofs in (...) CyLL + MIX. This can be viewed as a fully faithful representation of a free *-autonomous category, canonically enriched over vector spaces. This paper is a natural extension of the authors' previous work, "Linear Lauchli Semantics", where a similar theorem is obtained for the commutative logic MLL + MIX. In that paper, we interpret proofs as dinaturals which are invariant under certain actions of the additive group of integers. Here we also present a simplification of that work by showing that the invariance criterion is actually a consequence of dinaturality. The passage from groups to Hopf algebras in this paper corresponds to the passage from commutative to noncommutative logic. However, in our noncommutative setting, one must still keep the invariance condition on dinaturals. (shrink)

According to the causal interpretation of quantum mechanics, one can precisely define the state of an individual particle in a many-body system by its position, momentum, and spin. It is shown in the EPR spin experiment that the quantum torque brings about an instantaneous change in the state of one of the particles when the other undergoes a local interaction, but that such a transfer of “information” cannot be extracted by any experiment subject to the laws of quantum mechanics.

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

The doctrine of the mature minor began as an emergency exception to the rule of parental consent. Over time, the doctrine crept into cases that were non-emergent. In this essay, we show how the doctrine also developed in the context of the latter part of the 20th century, at the same time that the sexual revolution, the pill, and sexual liberation came to be seen as important symbols of female liberation—liberation that required that female minors be granted the status of (...) a mature minor. To do so moves sexual morality out of the domain of the family, where it had always been situated, and into the domain of the state. We also show how a phenomenological account of the care of the body in the family conforms to the latest in neuroscientific understandings of adolescent brain development. The family attenuates the dependency of adolescents and provides an important social contextualization for the care of the body, including the inculcation of sexual mores in adolescence. We conclude that the drive to push sexual decision making as a matter of state concern further undermines the foundations of the moral meanings of sex and sexuality. (shrink)

He served as chair of the Biology Department (...) and was instrumental in the establishment and success of the Center for Science in Society at Bryn Mawr College. (shrink)

We introduce a linear analogue of Läuchli's semantics for intuitionistic logic. In fact, our result is a strengthening of Läuchli's work to the level of proofs, rather than provability. This is obtained by considering continuous actions of the additive group of integers on a category of topological vector spaces. The semantics, based on functorial polymorphism, consists of dinatural transformations which are equivariant with respect to all such actions. Such dinatural transformations are called uniform. To any sequent in Multiplicative Linear Logic (...) , we associate a vector space of“diadditive” uniform transformations. We then show that this space is generated by denotations of cut-free proofs of the sequent in the theory MLL + MIX. Thus we obtain a full completeness theorem in the sense of Abramsky and Jagadeesan, although our result differs from theirs in the use of dinatural transformations.As corollaries, we show that these dinatural transformations compose, and obtain a conservativity result: diadditive dinatural transformations which are uniform with respect to actions of the additive group of integers are also uniform with respect to the actions of arbitrary cocommutative Hopf algebras. Finally, we discuss several possible extensions of this work to noncommutative logic.It is well known that the intuitionistic version of Läuchli's semantics is a special case of the theory of logical relations, due to Plotkin and Statman. Thus, our work can also be viewed as a first step towards developing a theory of logical relations for linear logic and concurrency. (shrink)
