Homegardens are traditional food systems that have been adapted over generations to fit local cultural and ecological conditions. They provide a year-round diversity of nutritious foods for smallholder farming communities in many regions of the tropics and subtropics. In southwestern Uganda, homegardens are the primary source of food, providing a diverse diet for rural marginalized poor. However, national agricultural development plans as well as economic and social pressures threaten the functioning of these homegardens. The implications of these threats are difficult (...) to evaluate, because the structure and functions of the homegardens are not well understood. The aim of the study was to identify patterns and influencing factors in the diversity of homegardens by documenting the floristic diversity and its interactions with spatial, environmental and socio-economic factors. A geographically and socially focused assessment of floristic diversity in 102 randomly selected homegardens in three districts of southwest Uganda was conducted along a deforestation gradient following a human ecology conceptual framework and testing multiple quantitative hypotheses regarding the above mentioned factors. A merged mixed-method approach was followed to provide context and feedback regarding quantitative findings. Results show a high total richness of 209 crop species dominated by food species, which constituted 96 percent of individuals and 44 percent of all species. Forest-edge homegardens maintained higher plant diversity compared to homegardens in deforested areas and near degraded wetlands. Multiple linear regression models indicated elevation, location, homegarden size, distance to market, additional land ownership and livestock ownership as significant predictors of crop diversity. Cluster analysis of species densities revealed four garden types: ‘diverse tree gardens’, ‘small forest-edge gardens’, ‘large, old, species-rich gardens’, and ‘large, annual-dominated herb gardens’, with 98% correct classification. Location, elevation, and garden size were also important determinants in the cluster assignment. We conclude that the diversity of the studied homegardens may be changing as part of adaptive traditional practices and in response to external drivers. The identified patterns illustrate the importance of homegardens for rural livelihoods and may offer some ways to support farmers to maintain these systems as relevant mechanisms for development in Uganda.

Though virtually unknown before 1851, the exceptionally scenic Yosemite Valley of California soon attracted continuing attention as a geological anomaly. J. D. Whitney, state geologist and Harvard professor, advocated a tectonic theory of its origin. Despite its seemingly official status, Whitney's theory even failed to convince some of his own subordinates. An unexpectedly effective dissenter not associated with Whitney was John Muir, then a tatterdemalion vagrant. Though the two men never met, conflict between their inflexible and (...) mutually exclusive geological theories persisted well into the twentieth century. Eventually, both dogmatists were proved wrong, but Muir had come closer to what we now accept. Several geological and geomorphological issues of importance entered into later discussions of Yosemite. The whole controversy, moreover, illuminates such further issues as the influence of preconceptions on theorizing, the role of authority in science, and the interactions of professionals with amateurs.

The present article presents Wang Fuzhi 王夫之 (1619-1692 C.E.)’s reading of the eighteenth chapter of the Zhuang-Zi 莊子 (ZZ) by looking at his entry from Zhuang-Zi-Tong 莊子通 and other key glosses from Zhuang-Zi-Jie 莊子解. The philosophical upshot, I aim to show, is that Wang takes ZZ as presenting the consummation of “the greatest joyousness” (zhi-le 至樂) as requiring getting rid of joyousness as one’s desideratum. Using Derek Parfit’s work as a point of reference, I aim to show that this is (...) not paradoxical or even inconsistent or even (directly or indirectly) self-defeating but is instead an interesting instance of a self-effacing theory.

Most ethical decisions are conditioned by formidable uncertainty. Decision makers may lack reliable information about relevant facts, the consequences of actions, and the reactions of other people. Resources for dealing with uncertainty are available from standard forms of decision theory, but successful application to decisions under risk requires a great deal of quantitative information: point-valued probabilities of states and point-valued utilities of outcomes. When this information is not available, this paper recommends the use of a form of decision theory that (...) operates on a bare minimum of information inputs: comparative plausibilities of states and comparative utilities of outcomes. In addition, it proposes a comparative strategy for dealing with second-order uncertainty. The paper illustrates its proposal with reference to a well-known ethical dilemma: Kant’s life-saving lie.

If one cannot establish givens, such as Platonic ideas, or determiners, such as Kantian categories, as a point of departure for philosophical inquiry, then how is philosophical inquiry to proceed in a non-question-begging manner? This, of course, is the familiar problem of grounding philosophical discourse. In this essay, I hope to offer a Zhuangzian solution—that is, a solution derived from analysis of the Zhuangzi 莊子 text—to this perennial philosophical problem. As a result, I hope to give the reader a critical (...) glimpse into a Zhuangzian philosophy without foundations, thereby providing a potential solution to the preceding problem while displaying the continued relevance of the Zhuangzi text.

To advance our understanding of both the Book of Zhuāngzǐ 莊子 (c. fourth to third century BCE) and Qián Mù 錢穆 (1895–1990)’s Zhuāngzǐ studies 莊學, I aim to squarely face one of the more obscure passages in the former with recourse to an explanation from the latter. The passage in question is that from the second chapter beginning with the claim ‘there is a beginning’ (有始也者) and culminating with the claim that ‘there has not yet begun to be a “there (...) has not yet begun to be nothing”’ (有未始有夫未始有無也者). I hope to show that Qián offers a compelling and novel interpretation of this difficult passage worthy of our consideration. (shrink)

The focus of this study is cognitive choice: the selection of one cognitive option (a hypothesis, a theory, or an axiom, for instance) rather than another. The study proposes that cognitive choice should be based on the plausibilities of states posited by rival cognitive options and the utilities of these options' information outcomes. The proposal introduces a form of decision theory that is novel because comparative; it permits many choices among cognitive options to be based on merely comparative plausibilities and (...) utilities. This form of decision theory intersects with recommendations by advocates of decision theory for cognitive choice, on the one hand, and defenders of comparative evaluation of scientific hypotheses and theories, on the other. But it differs from prior decision-theoretic proposals because it requires no more than minimal precision in specifying plausibilities and utilities. And it differs from comparative proposals because none has shown how comparative evaluations can be carried out within a decision-theoretic framework. (shrink)

A study in the philosophy of mind, centred on the problem of 'intentionality' the sense in which emotions can be said to have objects, their relation to these objects, and the implications of this relation for our understanding of human action and behaviour. Dr Wilson sets his enquiry against a broad historical background on what distinguishes man from inanimate objects by describing both Cartesian view of man is matter plus mind and the neo-Wittgensteinian view that there is a dynamic behavioural (...) difference – causal notions being often inapplicable to human action. Dr Wilson goes on to show the controversies and arguments that arise from the notion of intentionality cannot be analysed in causal terms. Dr Wilson believes that this notion can be shown causally and sets out to prove it. Finally, he brings this argument to a larger context mentioning that it has far-reaching effects in natural and social sciences. (shrink)

Thomas Nagel has held that transcendence requires attaining a point of view stripped of features unique to our perspective. The aim of transcendence on this view is to get at reality as it is, independent of our contributions to it. I show this notion of transcendence to be incoherent, yet defend a contrasting notion of transcendence. As conceived here, transcendence does not require striving for an external, objective viewpoint on nature or looking at matters from someone else's or an impartial (...) point of view. On my view, which builds on the work of Iris Murdoch, transcendence consists of a refinement of our concepts and sensibility to make them more adequate to the individuals we encounter.

Despite often being condemned for having a paradigmatically unrealistic or dangerous conception of power, Plato expends much effort in constructing his distinctive conception of power. In the wake of Socrates’ trial and execution, Plato writes about conventional, elitist, and radically unethical conceptions of power only to ‘refute’ them on behalf of a favoured conception of power allied with justice. Are his arguments as pathetic or wrong-headed as many theorists make them out to be – from Machiavelli to contemporary political realists, (...) from ‘political’ critics of Plato ranging from Popper to Arendt? And if not, has our understanding of power been impoverished? This question has been surprisingly unasked, and it is one I address by asking Plato and his critics: What are the dialectical moves Plato makes in refuting Socrates’s opponents and constructing his own conception of legitimate power? Exactly how does he interweave his conception of power with a kind of ethics? How does it compare to recent conceptions of political realism and the power-politics/ethics relationship – e.g., after Marx and Foucault? While addressing these questions I also attend to the issue of Plato’s historicity: to what extent do the limits of his language and world affect our reading of Plato and his political critics? Ultimately, I argue that and how Plato’s conception of power and its political dimensions realistically have much to teach us that we have not learned. (shrink)

Perturbations of quantum systems ranging from oscillators to fields can be either continuous or discontinuous functions of the coupling. The system under consideration is the familiar harmonic oscillator in one degree of freedom. Previous studies have shown that when the harmonic oscillator is subjected to a perturbation with a power law singularity, a permanent change in the system characteristics is observed for a specific range of power law values. The introduction of a logarithmic singularity into the power law potential fine (...) tunes the singularity power. (shrink)

From the days of Plato’s Academy, academic life and discourse have operated in tension with political life, and often the political life of democracy. Since World War II, this tension has been read as essentially antagonistic. In this survey of the relationship of the original and subsequent incarnations of the Academy to ancient Athens, republican Rome, and the Florentine city-state, it becomes clear that the tension was, in fact, potentially as much of an asset to democracy as an assault upon (...) it—even as the tension forever remained real. Readings of Plato and versions of the Academy become antagonistic to civic life only when their intellectual posture takes refuge in metaphysical doctrines or political ideologies that bear only marginal connections to the effective argument of Plato’s dialogues or the initial political postures of Academic life.

The following paper has two primary purposes. First it aims to articulate a theoretical proposition in general terms, namely, that every theory of doctrinal development presupposes a philosophy of history. The underlying significance of this proposition is that theories of doctrinal development are simultaneously narratives of the historical significance of the church’s pilgrimage through history, though that fact typically remains implicit in theories of doctrinal development. The second purpose is to illustrate the general proposition by analyzing a particularcase. I have (...) therefore outlined some of the salient features of John Henry Cardinal Newman’s theory of doctrinal development and, using ideas from Eric Voegelin’s philosophy, show how it implies a philosophy of history.

To be fully understood, contemporary forms of racism must be grasped as ethical ideologies rooted in an independent system of value classification. Racism does not merely result from an intrusion of strategic action on communicative action, as discourse ethicists might argue. In contemporary racism, the minority group is seen as perversely incapable of developing a capacity for the behavior that would constitute just moral reciprocity as decided in the contractual situation. Their standing as members of the moral community is thereby (...) qualilied To address racism discursively, the racist must be met with more than an abstract moral demand. Rather, racists must be confronted with the needs and capacities of the racial outsider, so that they might perceive her acts as virtuous and recognize the aptness of her use of value-concepts.

Henrike Jansen’s “The strategic formulation of abductive arguments in everyday reasoning” insightfully explores the terrain of abductive argumentation. The purpose of this note is to continue the exploration along lines marked out by her paper. This further exploration proceeds in two stages. Section 2 of the paper addresses the nature of abductive inference by distinguishing two types of abduction, identifying some of abduction’s formal and nonformal properties, and relating abduction to enthymematic inference. Section 3 focuses on some of Jansen’s examples, (...) paying particular attention to the distinction between abduction and argument from sign. Whereas Jansen maintains that some arguments from sign are not abductive, the paper suggests an alternative perspective from which arguments from sign can generally be viewed as one sort of abductive inference.

This article defends the philosophy of the Renaissance against a critique by Ortega y Gasset. Renaissance philosophy, it is argued, was a rebirth of the Hellenistic and Roman conviction that theory should not be pursued for its own sake; rather, it should be kept on a short leash controlled by practical ends. This Renaissance view is a precursor to the contemporary anti-theory of thinkers like Aranguren, Toulmin, and Williams.

In this paper, I investigate what I call “ecological value cognition,” a term designating a cognitive process by which one understands: (1) a value or set of values which pertain to the environment, (2) that such values are morally relevant, and (3) that these values may invite or even require virtues, attitudes or actions with respect to them and the entities which bear them. I seek, in this paper, to elucidate the nature of ecological value cognition and suggest specific challenges (...) that the American capitalist ethos poses for understanding these values and therefore for developing a sound environmental ethics and policy.

This article discusses what might be called the standard picture of Ockham in 20th century Catholic thought, especially as regards his theory of knowledge. First, it explains why it is that Ockham’s theory of knowledge has generally gotten bad press from Catholic philosophers. Second, it seeks to demonstrate why Ockham deserves a better reputation among Catholic thinkers.

Since its formation in 1947, the World Medical Association (WMA) has been a leading voice in international medical ethics. The WMA’s principal ethics activity over the years has been policy development on a wide variety of issues in medical research, medical practice and health care delivery. With the establishment of a dedicated Ethics Unit in 2003, the WMA’s ethics activities have intensified in the areas of liaison, outreach and product development. Initial priorities for the Ethics Unit have been the review (...) of paragraph 30 of the Declaration of Helsinki, the expansion of the Ethics Unit section of the WMA website and the development of an ethics manual for medical students everywhere.
