Given a finite state space and common priors, common knowledge of the identity of an agent with the minimal (or maximal) expectation of a random variable implies ‘consensus’, i.e., common knowledge of common expectations. This ‘extremist’ statistic induces consensus when repeatedly announced, and yet, with n agents, requires at most log2 n bits to broadcast.

Engineers’ love of technology often gets in the way of their being useful. Consider Post-it Notes or, better yet, plain paper notepads. These probably seemed like trivial ideas, but they turned out to be terribly useful. Why? Because the marvel that is the human brain has a horrible short-term memory, which means that dumb-as-dirt memory aids can make people substantially smarter.

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

This paper describes a Bayesian method for constructing a super-resolved surface model by combining information from a set of images of the given surface. We develop the theory and algorithms in detail for the 2-D reconstruction problem, appropriate for the case where all images are taken from roughly the same direction and under similar lighting conditions. We show the results of this 2-D reconstruction on Viking Martian data. These results show dramatic improvements in both spatial and gray-scale resolution. The Bayesian (...) approach uses a neighbor correlation model as well as pixel data from the image set. Some extensions of this method are discussed, including 3-D surface reconstruction and the resolution of diffraction blurred images. (shrink)

Primary works on Huang-Lao Taoism and Yin-yang philosophy, lost for more than two thousand years, are translated and prefaced with an informative introduction.

Phenomenology, according to Husserl, is meant to be philosophy as rigorous science. It was Franz Brentano who inspired him to pursue the ideal of scientific philosophy. Though Husserl began his philosophical career as an orthodox disciple of Brentano, he eventually began to have doubts about this orientation. The Logische Unterschungen is the result of such doubts. Especially after the publication of that work, he became increasingly convinced that, in the interests of scientific philosophy, he had to go in a direction (...) which diverged from Brentano and other members of this school (`Brentanists') who believed in the same ideal. An attempt is made here to ascertain Husserl's philosophical relation to Brentano and certain other Brentanists (Carl Stumpf, Benno Kerry, Kasimir Twardowski, Alexius Meinong, and Anton Marty). The crucial turning point in the development of these relations is to be found in the essay which Husserl wrote in 1894 (particularly in response to Twardowski) under the title `Intentional Objects' (which is translated as an appendix in this volume). This study will be of interest to historians of philosophy and phenomenology in particular, but also to anyone concerned with the ideal of scientific philosophy. (shrink)

While many of the phenomenological currents in philosophy allegedly utilize a peculiar method, the type under consideration here is characterized by Franz Brentano s ambition to make philosophy scientific by adopting no other method but that of natural science. Brentano became particularly influential in teaching his students (such as Carl Stumpf, Anton Marty, Alexius Meinong, and Edmund Husserl) his descriptive psychology, which is concerned with mind as intentionally directed at objects. As Brentano and his students continued in their investigations in (...) descriptive psychology, another side of Austrian phenomenology, namely object theory, became more and more prominent. The philosophical orientation under consideration in this collection of essays is accordingly a two-sided discipline, concerned with both mind and objects, and applicable to various areas of philosophy such as epistemology, philosophy of language, value theory, and ontology.".

The field of business ethics has been active for several decades, but it has yet to develop a generally agreed upon applied ethical perspective for the discipline. Academics in business disciplines have developed useful science-based models explaining why business people behave ethically but without a generally accepted definition of ethical behavior. Academics in moral philosophy have attempted to formulate what they believe ethical behavior is, but many seem to ignore or reject the basic mission of business. The purpose of this (...) article is to offer one view of ethics in business that accommodates the mission of business. This purpose is achieved by reviewing the mission of ethics in applied disciplines like business and melding it into the mission of business in capitalistic societies. (shrink)

One of the most important students of Franz Brentano was Anton Marty, who made it his task to develop a philosophy of language on the basis of Brentano’s analysis of mind. It is most unfortunate that Marty does not receive the attention he deserves, primarily due to his detailed and distracting polemics. In the analysis presented here his philosophy of language and other aspects of his thought, such as his ontology , are examined first and foremost in their positive rather (...) than critical character. The analysis is moreover supplemented by translations of four important works by Marty, including his entire work On the Origin of Language. These are in fact the first English translations of any substantial writings by him. The resulting picture that emerges from the analysis and translations is that Marty has much to say that proves to be of enduring interest for the philosophy of language on a range of topics, especially the meanings of statements, of emotive expressions, and of names as regards both their communicative and their ontological aspects. The volume will be of interest not only to philosophers and historians of philosophy, but also to historians of linguistics and psychology. (shrink)

For sociologist Emile Durkheim, the “sacred” constitutes all those things “set apart and forbidden.” Within Evangelical Christianity, and to a lesser degree Protestantism in general, the sacred has arguably centered on the individual believer and her/his personal relationship with God and scripture. Recently, however, a growing movement within Evangelical Christianity has emphasized the sacred nature of relationships and community, culminating in the mantra “God is love.” This shift has set community above the personal in the hierarchy of sacred Evangelical things, (...) and is reminiscent of earlier progressive forms of Evangelicalism, such as Social Gospel Christianity. Rob Bell, an Evangelical author, pastor, and Oprah Network star, possibly best exemplifies this change and its ramifications, which extend from a postcolonial critique of mission work and evangelism to a move to more inclusive and even Universalist soteriology. Such efforts that have left Bell labeled as a heretic in some Evangelical circles. (shrink)

Kenneth C. Schaffner's paper is an important contribution to the literature on behavioral genetics and on genetics in general. Schaffner has a long record of injecting real molecular biology into philosophical discussions of genetics. His treatments of the reduction of Mendelian to molecular genetics first drew philosophical attention to the problems of detail that have fuelled both anti-reductionism and more sophisticated models of theory reduction. An injection of molecular detail into discussions of genetics is particularly necessary at the present time, (...) when so many philosophers seem happy to discuss the philosophical and ethical implications of molecular biology using gene concepts derived from evolutionary biology ). Schaffner has long advocated the view that the philosophy of biology should be more than the philosophy of evolution. This paper shows how radically a picture of gene action derived from molecular biology undercuts the popular picture associated with a more evolutionary view of genes as units of heredity or as ‘difference-makers’ mediated by the ‘black box’ of development.

While Hermann Lotze's philosophy was widely received all over the world, his views on abstraction and Platonic ideas are of particular interest because they were to a large extent adopted by one of the most eminent philosophers of the twentieth century, namely Edmund Husserl. In this paper these views are examined in three distinct aspects. The first of these aspects is to be found in Lotze's thesis that there is a mental process, prior to abstraction, whereby "first universals" are apprehended. (...) The second one lies in his view that there is yet a higher level of apprehension, as found in the process of abstraction itself. According to Lotze, abstraction is not to be identified with the mere removal of particular features, but rather the replacement of these with first universals, resulting in "general images" and ultimately concepts. In addition to Lotze's analysis of the cognition of universals, there is finally a third thesis (an ontological one) which is examined in this paper, namely that the universals are Platonic Ideas in the sense that they have "validity" (Geltung) independently of their corresponding particulars and also of the mind which grasps them. The three claims in question are examined here in detail. Also, an attempt is made to point out some of the connections between Lotze and Husserl on the topic under discussion. (shrink)

This study represents an improvement in the ethics scales inventory published in a 1988 Journal of Business Ethics article. The article presents the distillation and validation process whereby the original 33 item inventory was reduced to eight items. These eight items comprise the following ethical dimensions: a moral equity dimension, a relativism dimension, and a contractualism dimension. The multidimensional ethics scale demonstrates significant predictive ability.

What emerges in Fischer’s phenomenological aesthetics is clearly the view that empathy is absolutely crucial not only to the apprehension of the aesthetic object, but also to the enjoyment of it. While this position certainly has merits, I have argued that in some ways his phenomenological description leaves something to be desired. This was particularly seen in his claim that empathy can never be described as an intuitive presentation of feeling. Perhaps another criticism which can be added here is be (...) found in a consideration of abstract works of art. In the case of these it would seem that empathy plays a much smaller role than it does in the apprehension of other aesthetic objects, especially works of art of other kinds. This is not to say that empathy could play no role at all in the apprehension of abstract works of art, for we may keep in mind that Fischer formulates the notion of mechanical empathy whereby one empathetically grasps power and other phenomena which are analogues of the will. It remains to be seen in the further development of a phenomenological aesthetics whether the notion of empathy can be applied in any other way in such cases. (shrink)

_Concept and Judgment in Brentano's Logic Lectures_ provides an analysis of an important feature of Brentano's philosophy in the 19th century. Relevant materials in both German and English are also included in the volume.

The influence of Franz Brentano in twentieth century philosophy has been extensive. His two most famous and outstanding pupils were Alexius Meinong and Edmund Husserl. These two are closely related not only regarding their common background in the school of Brentano, but also in their common concern with problems arising from British empiricism. Such a problem is to be found in the nominalist views of Locke, Berkeley, and Hume and their concomitant theories of general ideas. While Meinong's early work continues (...) in the empiricist tradition by characterizing general ideas in terms of abstraction and not in terms of general objects as their correlates, Husserl's _Logical Investigations_ are committed to the claim that general ideas can be described only as ideas which refer to general objects. In _Meinong and Husserl onion and Universals_ the epistemological, psychological, and ontological aspects of these theories are examined and compared. Included is also a translation of _Abstraction and Comparing_ by Meinong. (shrink)

That there is a heritable or familial component of susceptibility to chronic non‐communicable diseases such as type 2 diabetes, obesity and cardiovascular disease is well established, but there is increasing evidence that some elements of such heritability are transmitted non‐genomically and that the processes whereby environmental influences act during early development to shape disease risk in later life can have effects beyond a single generation. Such heritability may operate through epigenetic mechanisms involving regulation of either imprinted or non‐imprinted genes but (...) also through broader mechanisms related to parental physiology or behaviour. We review evidence and potential mechanisms for non‐genomic transgenerational inheritance of ‘lifestyle’ disease and propose that the ‘developmental origins of disease’ phenomenon is a maladaptive consequence of an ancestral mechanism of developmental plasticity that may have had adaptive value in the evolution of generalist species such as Homo sapiens.

Is privacy the key ethical issue of the internet age? This coauthored essay argues that even if all of a user’s privacy concerns were met through secure communication and computation, there are still ethical problems with personalized information systems. Our objective is to show how computer-mediated life generates what Ernesto Laclou and Chantal Mouffe call an “atypical form of social struggle”. Laclau and Mouffe develop a politics of contingent identity and transient articulation (or social integration) by means of the notions (...) of absent, symbolic, hegemonic power and antagonistic transitions or relations. In this essay, we introduce a critical approach to one twenty-first-century atypical social struggle that, we claim, has a disproportionate effect on those who experience themselves as powerless. Our aim is to render explicit the forms of social mediation and distortion that result from large-scale machine learning as applied to personal preference information. We thus bracket privacy in order to defend some aspects of the EU GDPR that will give individuals more control over their experience of the internet if they want to use it and, thereby, decrease the unwanted epistemic effects of the internet. Our study is thus a micropolitics in in the Deleuzian micropolitical sense and a preliminary analysis of an atypical social struggle.

Clinical ethics can be viewed as a practical discipline that provides a structured approach to assist healthcare practitioners in identifying, analysing and resolving ethical issues that arise in practice. Clinical ethics can therefore promote ethically sound clinical and organisational practices and decision-making, thereby contributing to health organisation and system quality improvement. In order to develop students’ decision-making skills, as well as prepare them for practice, we decided to introduce a clinical ethics strand within an undergraduate medical curriculum. We designed a (...) programme of clinical ethics activities for teaching and assessment purposes that involved using ethical frameworks to analyse hypothetical and real-life cases in uni- and inter- professional groups. In this paper, we draw on medical student feedback collected over 6 years to illustrate the appeal to students of learning clinical ethics. We also outline the range of benefits for students, healthcare organisations, and the field of clinical ethics arising from tomorrow’s doctors experiencing clinical ethics early in their training. We conclude by briefly reflecting on how including clinical ethics within tomorrow’s doctors curricular can secure and continue future engagement in clinical ethics support services in the UK, alongside the dangers of preparing students for organisational cultures that might not exist. We anticipate the findings presented in the paper will contribute to wider debates examining the impact of ethics teaching, and its ability to inform future doctors’ practice. (shrink)

There is a widespread feeling that health is special; the rules that are usually used in other policy areas are not applied in health policy. Health economists, for example, tend to be reluctant to offer economists' usual prescription of competition and consumer choice, even though they have largely failed to justify this reluctance by showing that health economics involves special features such as public goods, externalities, adverse selection, poor consumer information, or unusually severe consequences.

Discussions about abstraction are so important and so profound that this topic can hardly be neglected. It has inevitably cropped up again in various periods of philosophical enquiry. Despite these ancient roots and after the great debate that characterised the empirical and rationalistic tradition, interest in the problem has unfortunately been absent in large measure from the mainstream of mathematical logic and analytic philosophy. It seems that there is a gap between the epistemological theorization, in which it is difficult to (...) find new insights on the problem of abstraction, and the historical studies concerning the development of philosophical thought. Such studies, however, present a more fertile ground for such insights. Here the reader will find presented for the first time a collection of papers about the topic, considered from an historical point of view together with an awareness of the need for building a bridge between historical research and theoretical speculation. Accordingly the volume consists of both general overviews which sketch the signifcance and the fortunes of abstraction in science, philosophy and logic (the first part) and historical case studies which focus on abstraction in particular thinkers (the second part). This volume is of interest for both general philosophers and historians of philosophy. (shrink)

Attempts to model interstellar colonization may seem hopelessly compromised by uncertainties regarding the technologies and preferences of advanced civilizations. If light speed limits travel speeds, however, then a selection effect may eventually determine frontier behavior. Making weak assumptions about colonization technology, we use this selection effect to predict colonists’ behavior, including which oases they colonize, how long they stay there, how many seeds they then launch, how fast and far those seeds fly, and how behavior changes with increasing congestion. This (...) colonization model explains several astrophysical puzzles, predicting lone oases like ours, amid large quiet regions with vast unused resources. (shrink)

Humans have slowly built more productive societies by slowly acquiring various kinds of capital, and by carefully matching them to each other. Because disruptions can disturb this careful matching, and discourage social coordination, large disruptions can cause a “social collapse,” i.e., a reduction in productivity out of proportion to the disruption. For many types of disasters, severity seems to follow a power law distribution. For some of types, such as wars and earthquakes, most of the expected harm is predicted to (...) occur in extreme events, which kill most people on Earth. So if we are willing to worry about any war or earthquake, we should worry especially about extreme versions. If individuals varied little in their resistance to such disruptions, events a little stronger than extreme ones would eliminate humanity, and our only hope would be to prevent such events. If individuals vary a lot in their resistance, however, then it may pay to increase the variance in such resistance, such as by creating special sanctuaries from which the few remaining humans could rebuild society.

Many thinkers believe that the next transformational change in human organisation will be the onset of human-level artificial intelligence, and that the most likely method of achieving this will come through brain emulations or "ems": the ability to scan human brains and program their connections into ever faster computers. Taking this as his starting point, Hanson describes what a world dominated by these ems will be like.

The pace of scientific progress may be hindered by the tendency of our academic institutions to reward being popular rather than being right. A market-based alternative, where scientists can more formally 'stake their reputation', is presented here. It offers clear incentives to be careful and honest while contributing to a visible, self-consistent consensus on controversial scientific questions. In addition, it allows patrons to choose questions to be researched without choosing people or methods. The bulk of this paper is spent in (...) examining potential problems with the proposed approach. After this examination, the idea still seems to be plausible and worthy of further study. (shrink)

We study experimental markets where privately informed traders exchange simple assets, and where uninformed third parties are asked to forecast the values of these assets, guided only by market prices. Although prices only partially aggregate information, they significantly improve the forecasts of third parties. In a second treatment, a portion of traders are given preferences over the forecasts made by observers. Although we find evidence that these traders attempt to manipulate prices in order to influence the beliefs of observers, we (...) find no evidence that observers make less accurate forecasts as a result.
