Working memory limits are best defined in terms of the complexity of the relations that can be processed in parallel. Complexity is defined as the number of related dimensions or sources of variation. A unary relation has one argument and one source of variation; its argument can be instantiated in only one way at a time. A binary relation has two arguments, two sources of variation, and two instantiations, and so on. Dimensionality is related to the number of chunks, because (...) both attributes on dimensions and chunks are independent units of information of arbitrary size. Studies of working memory limits suggest that there is a soft limit corresponding to the parallel processing of one quaternary relation. More complex concepts are processed by or In segmentation, tasks are broken into components that do not exceed processing capacity and can be processed serially. In conceptual chunking, representations are to reduce their dimensionality and hence their processing load, but at the cost of making some relational information inaccessible. Neural net models of relational representations show that relations with more arguments have a higher computational cost that coincides with experimental findings on higher processing loads in humans. Relational complexity is related to processing load in reasoning and sentence comprehension and can distinguish between the capacities of higher species. The complexity of relations processed by children increases with age. Implications for neural net models and theories of cognition and cognitive development are discussed. (shrink)

The core issue of our target article concerns how relational complexity should be assessed. We propose that assessments must be based on actual cognitive processes used in performing each step of a task. Complexity comparisons are important for the orderly interpretation of research findings. The links between relational complexity theory and several other formulations, as well as its implications for neural functioning, connectionist models, the roles of knowledge, and individual and developmental differences, are considered.

Cowan's review shows that a short-term memory limit of four items is consistent with a wide range of phenomena in the field. However, he does not explain that limit, whereas an existing theory does offer an explanation for capacity limitations. Furthermore, processing capacity limits cannot be reduced to storage limits as Cowan claims.

We propose that the missing link from nonhuman to human cognition lies with our ability to form, modify, and re-form dynamic bindings between internal representations of world-states. This capacity goes beyond dynamic feature binding in perception and involves a new conception of working memory. We propose two tests for structured knowledge that might alleviate the impasse in empirical research in nonhuman animal cognition.

Richard Janko's acclaimed translation of Aristotle's _Poetics_ is accompanied by the most comprehensive commentary available in English that does not presume knowledge of the original Greek. Two other unique features are Janko's translations with notes of both the _Tractatus Coislinianus_, which is argued to be a summary of the lost second book of the Poetics, and fragments of Aristotle’s dialogue On Poets, including recently discovered texts about catharsis, which appear in English for the first time.

A distinction is commonly drawn between continuous sedation until death and physician-assisted suicide/euthanasia. Only the latter is found to involve killing, whereas the former eludes such characterization. I argue that continuous sedation until death is equivalent to physician-assisted suicide/euthanasia in that both involve killing. This is established by first defining and clarifying palliative sedation therapies in general and continuous sedation until death in particular. A case study analysis and a look at current practices are provided. This is followed by a (...) defense of arguments in favor of definitions of death centering on higher brain (neocortical) functioning rather than on whole brain or cardiopulmonary functioning. It is then shown that continuous sedation until death simulates higher brain definitions of death by eliminating consciousness. Appeals to reversibility and double effect fail to establish any distinguishing characteristics between the simulation of death that occurs in continuous sedation until death and the death that occurs as a result of physician-assisted suicide/euthanasia. Concluding remarks clarify the moral ramifications of these findings. (shrink)

Confucianism’s long historical association with despotism has cast doubts on its compatibility with democracy, and raise questions about its relevance in contemporary societies increasingly dominated by democratic aspirations. “Confucian democracy” has been described as a “contradiction in terms” and Asian politicians have appropriated Confucianism to justify resistance to liberalization and democratization. There has been a lively debate over the question of whether democracy can be found in Confucianism, from ancient texts such as the Analects and Mencius, to Confucian institutions such (...) as those recommended by Song dynasty Huang Zongxi. Philosophers have examined similarities and differences between Western ideas, such as autonomy, liberty, and rights, that are central to democratic theories on the one hand and Confucian ideas of virtue, ren, yi, li, zhi, exemplary person and authority. Scholars have studied the biographical accounts of prominent Confucians to understand the Confucian ideal person and society. Works arguing that there are elements of democracy in Confucianism, or that some Confucian ideas could provide the basis for a contemporary Confucian democracy, differ in the kind of democracy they choose as models. Liberal democracy was the model of earlier works; with increasing criticisms of liberal democracy in the past decades, a growing number of works arguing for Confucian democracy seek alternatives to liberal democracies, many proposing some kind of communitarian democracy as having affinity with the Confucian philosophical orientation. Besides conceptions of democracy that view it in terms of political systems, Dewey’s conception of democracy as the idea of community and primarily a moral ideal has also inspired attempts to reconstruct Confucian democracy.

This inclusive, cross-cultural study rethinks the nexus between engineering, development, and culture. It offers diverse commentary from a range of disciplinary perspectives on how the philosophies of today’s cultural triumvirate—American, European and Chinese—are shaped and given nuance by the cross-fertilization of engineering and development. Scholars from the humanities and social sciences as well as engineers themselves reflect on key questions that arise in this relational context, such as how international development work affects the professional views, identities, practice and ethics of (...) engineers. The first volume to offer a systematic and collaborative study that cuts across continental boundaries, the book delineates the kinds of skills and competences that tomorrow’s engineering success stories will require, and analyzes fascinating aspects of the interplay between engineering and philosophy, such as how traditionally Chinese ways of thinking can influence modern engineering practice in the world’s most populous country. China’s problematic mix of engineering woes and wonders, from the high-profile crash on its high-profile rail network to its ‘bird’s nest’ Olympic stadium, adds to the urgency for reform, while Europe’s Enlightenment-informed legal frameworks are contrasted with Chinese mechanisms in their governance of the field of nanotechnology, a crucial element of future technical evolution. Fascinating and compelling in equal measure, this volume addresses one of the topics at the leading edge of humanity’s quest to survive, and to thrive.​. (shrink)
