_Conjectures and Refutations_ is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

This paper explores how transformative experience generates decision-making problems of particular seriousness in medical settings. Potentially transformative experiences are especially likely to be encountered in medicine, and the associated decisions are confronted jointly by patients and clinicians in the context of an imbalance of power and expertise. However in such scenarios the principle of informed consent, which plays a central role in guiding clinicians, is unequal to the task. We detail how the principle’s assumptions about autonomy, rationality and information handle (...) transformative experiences poorly, appealing to several difficult cases for medical decision-making to illustrate the resulting problem, and we consider how the existing literature on complications with consent fails to offer a resolution. We argue that recognition of the problem has a role to play in achieving a more effective response to transformative decisions. In Sect. 1 we introduce several representative cases of challenging patient decision-making that clinicians might face. In Sect. 2 we detail how transformative experience has been analysed in the recent literature, before outlining in Sect. 3 the theoretical basis of the principle of informed consent, which plays a central role in how clinicians are expected to support decision-making. In Sect. 4, having laid the groundwork for a clear description, we return to the cases given in Sect. 1 to confirm how their transformative nature presents a problem: either clinicians treat the decisions faced by these patients as ‘normal’, encouraging them to focus on information provision that patients may be unable to act on, or they treat them as transformative, in which case they lack the resources to recognise whether they are helping patients make (subjectively) good decisions. In Sect. 5 we argue that the existing literature does not offer any escape from this problem. We close in Sect. 6 by noting the significant impact that appreciating the problem of transformative experience could have on supporting transformative decisions in medicine and briefly suggesting how we might aim to develop new approaches to dealing with these.

Farmers of the Peruvian Andesmake use of seed-size variation as a source offlexibility in the production of ``nativecommercial'' farmer varieties of Andeanpotatoes and ulluco. In a case study of easternCuzco, the use of varied sizes of seed tubers isfound to underpin versatile farm strategiessuited to partial commercialization (combinedwith on-farm consumption and the next season'sseed). Use of seed-size variation also providesadaptation to diverse soil-moistureenvironments. The importance and widespread useof seed-size variation among farmers isdemonstrated in the emphasis and consistency oflinguistic expressions about (...) this trait. Smalland small-medium seed is typically sown in thecommunity's ``Hill'' unit of sub-humid,upper-elevation agriculture. Seed tubers ofmedium-size and larger are needed fordrought-stressed locales in lower-elevationlandscape units. Farm-level preferences for theseed-size of tubers also suggest potentialrelations to resource endowments of farmhouseholds and gender-related management,although these tendencies were notstatistically significant in the study. Anintra-varietal, landscape-environmentalperspective on seed-size management, whichincludes an emphasis on within-fieldversatility, helps to strengthen the researchsupport of local seed production in policiesand programs aiming for in situagrobiodiversity conservation, marketingcapacity, and food security.

Mit dem vorliegenden Band wird Manfred Riedel, ein Schuler von Ernst Bloch, Karl Lowith und Hans-Georg Gadamer geehrt. Er anerkennt zugleich ein philosophisches Lebenswerk, das sich nicht an ferne utopische Ziele verlor, sondern mit dem historischen Leidensweg des geteilten und seit 1990 geeinten Deutschland untrennbar verbunden ist. Widergespiegelt wird das breite Spektrum seines philosophischen Denkens, das von der Lehre einer zweiten, praktischen Philosophie uber die Geschichtsvisionen einer Burgergesellschaft in Antike und Neuzeit zu der Gewichtung einer akroamatischen - das Horen (...) auf die Sprache erorternden - Hermeneutik und dem Zusammenhang von Denken und Dichten bei Nietzsche und den grossen Lyrikern der klassischen Moderne reicht. Die Beitrage, u. a. von Dieter Borchmeyer, Felix Duque, Jean Grondin, Werner Hecht, Agnes Heller, Hans Kock, Peter Horst Neumann, Fulvio Tessitore und Giuseppe Cacciatore, sind Zeugnisse dieses Weges und der internationalen Verbindungen des Geehrten.

A central claim in abortion ethics is what might be called the Harm Claim – the claim that abortion harms the fetus. In this article, we put forward a simple and straightforward reason to reject the Harm Claim. Rather than invoking controversial assumptions about personal identity, or some nonstandard account of harm, as many other critics of the Harm Claim have done, we suggest that the aborted fetus cannot be harmed for the simple reason that it does not occupy any (...) well-being level.

‘If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men.’ - Karl Popper, from the Preface Written in political exile during the Second World War and first published in two volumes in 1945, Karl Popper’s The Open (...) Society and Its Enemies is one of the most influential books of all time. Hailed by Bertrand Russell as a ‘vigorous and profound defence of democracy’, its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems and through underground editions become an inspiration to lovers of freedom living under communism in Eastern Europe. Popper’s highly accessible style, his erudite and lucid explanations of the thoughts of great philosophers and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of The Open Society and Its Enemies and why it demands to be read today and in years to come.

Much contemporary ontological inquiry takes place within the so-called ‘Quinean tradition’ but, given that some aspects of Quine’s project have been widely abandoned even by those who consider themselves Quineans, it is unclear what this amounts to. Fortunately recent work in metaontology has produced two relevant results here: a clearer characterisation of the metaontology uniting the aforementioned Quineans, most notably undertaken by Peter van Inwagen, and a raft of criticisms of that metaontology. In this paper I critique van Inwagen’s Quinean (...) metaontology, finding that certain challenges, supplemented by pressure to reflect more closely Quine’s work, should drive Quineans to adopt a stronger metaontology incorporating more of Quine’s radical views. I conclude that while van Inwagen’s Quineanism is problematic there are prospects for a viable, more wholeheartedly Quinean, metaontology. (shrink)

[A]ny theory of practical rationality must explain— or explain away—the following: Rational: In many cases, what it is rational (in some sense) for one to do or intend to do depends on what one desires. [...] I argue that in order to capture the rational significance of desire, we need to consider both its content and its force, on analogy to the rational significance of both the force and content of beliefs and perceptual experiences. This will open up a new (...) and more elegant way of explaining Rational, while also allowing us to understand how our desires provide us with a basic form of normative experience. Thus, in the end, this will provide the basis for a novel defense of the ancient thesis that desire, in some sense, presents its object under the “guise of the good.”. (shrink)

Die These von einer Achsenzeit in der Weltgeschichte Die zentrale Annahme dieses Buches ist die universalgeschichtliche These von einer Achsenzeit (880-200 v. Chr.) in der Weltgeschichte, in der voneinander unabhangig in China, Indien und dem Abendland strukturell ahnliche kulturelle Revolutionen und Aufbruche erfolgt sind. Inwieweit diese Aufbruche fur das kulturelle Leben in der Gegenwart weiterhin bedeutsam sind, wird heute in kulturwissenschaftlichen Disziplinen wie der Religions- und Kultursoziologie, der vergleichenden Kulturtheorie, der Theorie der Moderne u.a. neu diskutiert. Neben der These von (...) der Achsenzeit wird in Vom Ursprung und Ziel der Geschichte u.a. der Stellenwert von Wissenschaft und Technik in der Moderne erortert; es werden Uberlegungen uber eine mogliche Welteinheit (im Sinne eines Weltfriedenszustandes) angestellt sowie zeitgeschichtliche Tendenzen in der Politik (z.B. Totalitats- und Planungsideologien) kritisiert, die im Gegensatz zu Jaspers' liberalem Ethos der Freiheit und der Humanitat stehen. (shrink)

This book explores the main stages and key concepts in the development of Kant's critical philosophy, from the early 1760s to the 1790s. Karl Ameriks provides a detailed and concise account of the main ways in which the later critical works provide a plausible defense of the conception of humanity's fundamental end that Kant turned to after reading Rousseau in the 1760s. Separate essays are devoted to each of the three Critiques, as well as to earlier notes and lectures (...) and several of Kant's later writings on history and religion. A final section devotes three chapters to post-Kantian developments in German Romanticism, accounts of tragedy up through Nietzsche, and contemporary philosophy. The theme of an elliptical path is shown to be relevant to these writers as well as to many aspects of Kant's own life and work. The topics of the book include fundamental issues in epistemology and metaphysics, with a new defense of the Amerik's 'moderate' interpretation of transcendental idealism. (shrink)

Why do brains have so many connections? The principles exposed by Andy Clark provide answers to questions like this by appealing to the notion that brains distil causal regularities in the sensorium and embody them in models of their world. For example, connections embody the fact that causes have particular consequences. This commentary considers the imperatives for this form of embodiment.

'I want to begin by declaring that I regard scientific knowledge as the most important kind of knowledge we have', writes Sir Karl Popper in the opening essay of this book, which collects his meditations on the real improvements science has wrought in society, in politics and in the arts in the course of the twentieth century. His subjects range from the beginnings of scientific speculation in classical Greece to the destructive effects of twentieth century totalitarianism, from major figures (...) of the Enlightenment such as Kant and Voltaire to the role of science and self-criticism in the arts. The essays offer striking new insights into the mind of one of the greatest twentieth century philosophers. (shrink)

Alongside the direct parallels and contrasts between traditional narrative fiction and games, there lie certain partial analogies that provide their own insights. This article begins by examining a direct parallel between narrative fiction and games—the role of fictional reliefs and reality checks in shaping aesthetic engagement—before arguing that from this a partial analogy can be developed stemming from a feature that distinguishes most games from most traditional fictions: the presence of rules. The relation between rules and fiction in games has (...) heretofore been acknowledged but not examined in detail, giving an impression of a tension that is constant. However, the paired concepts of formal reliefs and representation checks, once introduced, allow us to explain how rules and fiction interact to alter the ways in which players engage with games in a dynamic but limited way.

A 2016 article in the Journal of Consumer Research argues that busyness has become a status symbol. In earlier societies, such as the 19th century Thorstein Veblen describes in his Theory of the Leisure Class, the wealthy conspicuously avoided work. They saw idleness as an ideal. By contrast, contemporary Americans praise being overworked. They see busy individuals as possessing rare and desirable characteristics, such as competence and ambition. -/- To respond philosophically to our new overworked overlords and status icons, we (...) need only return to the 19th century Danish philosopher Søren Kierkegaard. Kierkegaard is known for his philosophical account of boredom, which is often associated with idleness. If busyness is the opposite of idleness, perhaps he can diagnose busyness also. (shrink)

Soren Kierkegaard (1813‐1855) is primarily known as a moral philosopher. This chapter looks at his contributions to ethics, and shows how Kierkegaard's writings can contribute to epistemology, metaphysics, and other areas of contemporary philosophy. In order to contextualize Kierkegaard's contributions to philosophy the chapter briefly surveys some of the ways Kierkegaard is connected to nineteenth‐century philosophers, as well as classical figures like Socrates. It considers Kierkegaard's contributions to moral philosophy in two ways. First, the chapter briefly recounts Kierkegaard's suspicion of (...) Hegelian social ethics as discussed in Fear and Trembling. While Works of Love contains much of Kierkegaard's mature ethical thought, the former text may still serve as an introduction to his approach. Second, the chapter discusses several specific ways Kierkegaard can contribute to contemporary ethics. It also considers future directions for Kierkegaard scholarship and identifies some other areas of philosophy to which Kierkegaard's writings might contribute. (shrink)

Each of us experiences two conflicting attitudes towards time. On the one hand, we all, at least to some degree, look ahead towards the future. On the other hand, we sometimes feel like we ought to live in the present, without this concern about the future. Derek Parfit claims that we would be happier if we lacked our focus on the future: we would not be sad when good things were in the past, we could take life’s pleasures as they (...) come, and we would have fewer reasons to regret aging and death. Given his emphasis on the future as a philosophical problem, Kierkegaard seems especially challenged by Parfit’s claims. I argue that a response to Parfit’s challenges can be found in Kierkegaard’s discourses on the lily of the field and the bird of the air. Though not often read philosophically, these discourses also contribute to Kierkegaard’s philosophy of time. They can provide readers of Kierkegaard with a response to Parfit’s challenges by proffering a way to care for the future while living in the present. To defend this thesis, my first chapter recounts Parfit’s challenges and extant responses by readers of Kierkegaard to them. Chapters Two and Three develop Kierkegaard’s metaphysics of time by working through The Concept of Anxiety and Philosophical Fragments. The former chapter emphasizes Kierkegaard’s focus on the eschatological future while showing how Kierkegaard can contribute to contemporary debates within the philosophy of time. The latter considers Kierkegaard’s Christology and Trinitarian theology by working through Kierkegaard’s understanding of the past event of the incarnation. The fourth and fifth chapters discuss the ethical implications of Kierkegaard’s metaphysics of time through readings of Christian Discourses and Works of Love. Chapter Four contains my account of the attitude towards time Kierkegaard exhorts us to adopt: facing away from the future and towards the work we are called to do in the present. Chapter Five concludes by discussing the implications of this account for the ways we hope for and love our neighbors. (shrink)

Every theory of modernity must at least presuppose an implicit ontology of the social-historical. Castoriadis is one of the few who makes these presuppositions explicit. Castoriadis’s socio-cultural ontology reveals that the essentially indeterminate nature of the social-historical entails ontological plurality, in the face of which monological or unilinear theories of modernity collapse — leaving us with a fragmented field of tensions. Castoriadis’s exposition of the ontological plurality of the social-historical is one of his most important contributions to social theory — (...) but when he turns his attention to modernity, he immediately polarizes the field. The aim here is to offer some correctives to Castoriadis’s polarized depiction, primarily by teasing out tensions in his work. (shrink)

This article argues that, under likely empirical conditions, sufficientarianism leads not to an easily achievable duty to maintain a social minimum but to the onerous duty of maintaining a social maximum at the sufficiency level. This happens because sufficientarians ask us to give no weight at all to small benefits for people above the sufficiency level if the alternative is to relieve the suffering of people below it. If we apply this judgment in a world where there are rare diseases (...) and hard-to-prevent accidents that cause people to fall below the sufficiency threshold, all of our discretionary spending will have to be devoted to bringing harder and harder cases up to sufficiency. Nothing will be left for anyone to consume above the sufficiency level. (shrink)

This paper uses two techniques to build a socially responsible portfolio of U.S. equities and examines prospective performance using publicly available data. The first technique eliminates stocks from consideration using categorical exclusions with a restrictive Environment, Social and Governance screen. The paper shows that stocks surviving the screen have a significantly higher average projected Value Line alpha and are more likely to have a Morningstar 5-star rating. Using categorical exclusions, however, introduces a sector bias in that the ESG screen is (...) more likely to restrict stocks from the manufacturing sector than the service sector. The second technique does not introduce a sector bias because it uses a best-in-class optimization approach in place of screening. The paper introduces a linear programming model called Data Envelopment Analysis to the application of SRI portfolio development to find the best financially and socially performing companies within each industry sector. When compared to a categorical exclusions portfolio, a DEA portfolio is rated significantly higher by Morningstar and Value Line. Depending on the specific needs of a socially responsible investor, the DEA technique could be a better tool in developing a financially and socially balanced equity portfolio. (shrink)

Japan has more robots than any other country with robots contributing to many areas of society, including manufacturing, healthcare, and entertainment. However, few studies have examined Japanese attitudes toward robots, and none has used implicit measures. This study compares attitudes among the faculty of a US and a Japanese university. Although the Japanese faculty reported many more experiences with robots, implicit measures indicated both faculties had more pleasant associations with humans. In addition, although the US faculty reported people were more (...) threatening than robots, implicit measures indicated both faculties associated weapons more strongly with robots than with humans. Despite the media’s hype about Japan’s robot ‘craze,’ response similarities suggest factors other than attitude better explain robot adoption. These include differences in history and religion, personal and human identity, economic structure, professional specialization, and government policy. Japanese robotics offers a unique reference from which other nations may learn. (shrink)
