When Van Rensselaer Potter coined the English word “bioethics”, he envisioned a field that would bring together biological understanding and ethical values to address global environmental problems. Following Potter’s broad vision of bioethics, I explore ethical ideas that we need to address climate change. However, I develop and emphasize ideas about justice and responsibility in ways that Potter did not. At key points, I contrast the ideas that I develop with those in Potter’s work, but I try to avoid (...) scholarly debates and stay focused on the practical task: developing ideas to help us address climate change. To begin, I describe the problem of climate change. Then I show how it raises deep and serious issues of justice. Since the issues of justice are relatively clear and compelling, I proceed to focus attention on issues of responsibility – on why and how to respond to the structural injustices of climate change. I also note how my emphasis on justice and responsibility raises two new issues. To conclude, I mention the role of ecological citizens in bringing about social change. (shrink)

I first met Van Potter nearly 40 years ago when I was 17 and entering the University of Wisconsin as a new freshman. During the summer of 1963, Van was a participant in a series of evening seminars designed to familiarize premed students to the community at the University of Wisconsin Medical School. I was immediately struck by Van's unique ability to cut straight to the core of virtually any issue having to do with biomedicine. As with many of his (...) students, I quickly found myself in a father-son relationship of both our making. Van has been a source of inspiration and guidance to me ever since. (shrink)

Van Rensselaer Potter was the first voice to utter the word “bioethics,” yet he is too little appreciated by the bioethics community. My expectations for my first visit with Professor Van Rensselaer Potter were primed by conversations with leaders and historians of the field of biomedical ethics, including Warren Reich, Al Jonsen, and David Thomasma. When mentioning my interest in environmental ethics and my concerns for the current state of biomedical ethics, I was told that I must meet (...) Van. On my first visit to Madison, Wisconsin, Van met me at the McArdle Laboratories for Cancer Research at the University of Wisconsin, where he spent essentially his entire academic career as a basic oncological researcher. He was dressed informally and driving a rusting1984 Subaru station wagon with a license plate that read YES ZPG. We spent this first portion of our visit at the Institute where he is an Emeritus Professor and has contributed to understanding cancer metabolism as recognized by his election to the National Academy of Sciences. However, Van felt most at home in his shack located outside Madison. This country retreat included a rather primitive hut surrounded by acres of property owned by the family. I felt at the heart of Van's world when I sat in one of a pair of inexpensive plastic outdoor chairs in a particularly secluded part of the woods on the property, the place where Van himself communed with nature.

Mindful of how the history of bioethics has often been presented, we explore the background, contributions, and influence of Van Rensselaer Potter on the roots of bioethics. In the last few decades, dozens of papers have been written and published, including several doctoral theses and defenses on V. R. Potter‘s concept of bioethics. In those works, the context of the emergence of Potter’s bioethics has sometimes been suggested, but never analyzed thoroughly. We identify seven pillars of influence for Van (...) Rensselaer Potter’s bioethical credo, drawing on several facts from the rich cultural heritage of Wisconsin, where Potter had lived and worked for the most part of his life. (shrink)

Hugh Lloyd-Jones was an eminent Latin scholar who, during the Second World War, learnt Japanese and was posted to the Wireless Experimental Centre near Delhi. He became Regius Professor of Greek at the University of Oxford and was elected a Fellow of the British Academy in 1966. Obituary by Nigel Wilson FBA.

The leadership development industry regularly claims to aid in developing effective, ethical leaders, using 360-degree psychometric assessments as key tools for so doing. This paper analyses the effects of such tools on those subjected to and subjectivised by them from a Foucauldian perspective. We argue that instead of encouraging ethical leadership such instruments inculcate practices and belief systems that perpetuate falsehoods, misrepresentations and inequalities. ‘Followers’ are presumed compliant, malleable beings needing leaders to determine what is in their interests. Such techniques (...) pursue productivity and profitability, rather than ethical leadership. We examine the Multifactor Leadership Questionnaire, a widely used 360-degree tool that measures transformational leadership, as an illustrative case study to substantiate these criticisms. (shrink)

De acordo com a concepção dominante de causação, eventos espácio-temporalmente localizáveis que podem ser designados por termos singulares e descrições definidas são os únicos relata genuínos da relação causal. Isto dá apoio e é apoiado pela dicotomia aceita entre a explicação causal, concebida como uma relação intensional entre fatos ou verdades, e a relação natural e extensional da causação. O ensaio questiona este modo de ver e argumenta pela legitimidade da noção de causação por fatos: os relata de muitas relações (...) expressas pelo conector sentencial ‘(O fato) C causa (o fato) E’ podem ser causas e efeitos genuínos (I). Esta visão expandida da causação é então aplicada ao problema da causação mental. Assumindo a verdade do realizacionismo físico, o ensaio explora a conexão entre eficácia causal e relevância contrafactual de propriedades. Mostra-se que, pelo menos em muitos casos, as ligações contrafactuais corretas, requeridas pela causação, podem ser encontradas somente no nível dos fatos realizados, não no nível mais básico dos fatos realizadores (II). Finalmente, dadas as similaridades entre a defesa do fisicismo não-reducionista esboçada aqui e as tentativas menos modestas de justificação científica das pretensões do materialismo metafísico, justamente criticadas por van Fraassen como manifestações da ‘falsa consciência’, considera-se se e como a argumento principal do ensaio pode evitar o juízo crítico de van Fraassen (III).

6 and 14 recently proposed taxonomies that distinguish between four processing states, based on bottom-up stimulus strength and top-down attentional amplification. The aim of the present study was to empirically test these processing states using the priming paradigm. Our results showed that attention and stimulus strength significantly modulated priming effects: either receiving top-down attention or possessing sufficient bottom-up strength was a prerequisite for a stimulus to elicit priming. When both top-down attention and sufficient bottom-up strength were present, the priming effect (...) was boosted. The origins of the observed priming effects also varied between different processing states. We can conclude that our empirical study using the priming paradigm confirmed the presence of four processing states, which displayed a differential pattern of response priming effects and differential origins of the response priming effects.

If evolutionary history were to be replayed from the beginning, what would be the same, and what would be likely different? Would there be a human-like species, multicellularity, or even DNA? There is a great variety in the answers biologists give to this question, despite having the same access to empirical data and biological theory. For instance, Stephen J. Gould has claimed that evolutionary history is radically contingent, while Conway Morris holds that it converges onto specific biological structures that are (...) favored by natural selection. Others such have proposed that evolutionary history is characterized by an inexorable increase in complexity, while others see it as an evolutionary arms race. In this dissertation I investigate the fundaments underlying claims biologists make about contingency and directionality in evolutionary history as a whole. The topics of convergence and contingency have received attention from philosophers of biology in recent years, but the foundations of interpretations of evolutionary history as a whole remains a relatively neglected field. Hence the primary objective of this dissertation was not to defend this or that account, but rather to show a method by which these fundamental issues can be identified and analyzed constructively. The dissertation is organized into two parts, each dedicated to a single problem. The first part concerns the problem of ‘description dependence’: claims about the contingency of evolutionary outcomes depend on how these outcomes and the evolutionary process itself are described. I set out to map the different ways in which the contingency of outcomes changes as the phenomena are described in more and in less detail, and as broader or narrower subsets of evolutionary history are taken into account. That such an analysis is useful to pursue, I attempt to show by applying it to two of the most prominent interpretations of evolutionary history, those of Gould and Conway Morris. According to how their claims about evolutionary history are analyzed, one can arrive at opposing conclusions about the contingency of evolutionary outcomes. The second part concerns the problem of ‘causal complexity’: evolutionary history is a complex mess of unrelated causal processes, and for every generalization there is an exception. This raises the question whether non-speculative generalizations over evolutionary history as a whole are even possible. Limiting the scope of the investigation to the mechanism of natural selection alone, I consider first whether and how natural selection may be expected to give rise to trends at all. Some philosophers reject that natural selection is a cause at all, and that all evolution is simply an accumulation of births and deaths. If any trend occurs at all, it is due to a confluence of unrelated causal processes that could easily not have occurred. I argue against this by showing that these philosophers overlook the issue of time-scale: causal processes may make a difference for reproductive outcome at a time-scale of a single generation without them making a difference at the time-scale of multiple generations. With this distinction in mind, one can argue that natural selection causes a population to tend towards equilibrium. If a yet longer time-scale is taken – not that of multiple generations in a single environment, but that of many species and genuses across many environments – the challenge of causal complexity becomes much more difficult to overcome. Drawing on the phenomenon of phenotypic plasticity and niche construction, I argue that selection for plasticity ‘feeds’ on this complexity and variability in the environment. The trend in plasticity is unique in this regard, since trends in other types of adaptation are interrupted by the variability of complex environments. (shrink)

Probability kinematics is the theory of how subjective probabilities change with time, in response to certain constraints . Rules are classified by the imposed constraints for which the rules prescribe a procedure for updating one's opinion. The first is simple conditionalization , and the second Jeffrey conditionalization . It is demonstrated by a symmetry argument that these rules are the unique admissible rules for those constraints, and moreover, that any probability kinematic rule must be equivalent to a conditionalization preceded by (...) a determination of the values x i to be given to the members of such a partition. Next two rival rules which can go beyond such conditionalization are described. INFOMIN and MTP . Their properties are investigated and compared. (shrink)
