Spatial evolutionary game theory explains how cooperative traits can survive the intense competition in biological systems. If the spatial distribution allows cooperators to interact with each other frequently, the benefits of cooperation will outweigh the losses due to exploitation by selfish organisms. However, for a cooperative behavior to get established in a system, it needs to be found initially in a sufficiently large cluster to allow a high frequency of intracooperator interactions. Since mutations are rare events, this poses the question (...) of how cooperation can arise in a biological system in the first place. We present a simple model which captures two concepts from genetics that can explain how evolution overcomes the emergence problem. The first concept is, often in nature, a gene may not express its phenotype except under specific environmental conditions, rendering it to be a “silent” gene. The second key idea is that a neutral gene, one that does not harm or improve an organism’s survival chances, can still spread through a population if it is physically near to another gene that is positively selected. Through these two ideas, our model offers a possible solution to the fundamental problem of emergence of cooperation in biological systems. (shrink)

This major study examines the most fundamental categories in terms of which we conceive of ourselves, critically surveying the concepts of substance, causation, agency, teleology, rationality, mind, body and person, and elaborating the conceptual fields in which they are embedded. The culmination of 40 years of thought on the philosophy of mind and the nature of the mankind Written by one of the world’s leading philosophers, the co-author of the monumental 4 volume _Analytical Commentary on the Philosophical Investigations_ Uses broad (...) categories, such as substance, causation, agency and power to examine how we think about ourselves and our nature Platonic and Aristotelian conceptions of human nature are sketched and contrasted Individual chapters clarify and provide an historical overview of a specific concept, then link the concept to ideas contained in other chapters.

This article, written by a former justice of the Supreme Court of India and chairman of the Press Council of India, describes the media accountability system in India and argues for the global necessity for such systems. It declares the need for free press systems for the survival of democratic institutions and claims that society has an obligation to monitor media systems so they remain free. The alternative will be government regulation, which will suspend the vital characteristics of a free (...) press. A press council, on the other hand, can work more cooperatively with the press to assure responsibility. Global forces make it important for the mass media to explore the virtues inherent in media accountability systems, such as press councils. This article suggests why those systems are increasingly important, proposes structures and functions for such councils, and uses the Press Council of India as an example of a working organization.

Entertainments and celebrations are meant to give audiences and participants pleasure. Pleasure and enjoyment are an integral part of flourishing human life, and the desire for pleasure and enjoyment is a distinctive aspect of human nature. Psychological hedonism is a descriptive doctrine concerned with giving an account of actual human motivation. Ethical hedonism is a prescriptive doctrine that advances the view that human beings ought to pursue pleasure and avoid pain, that prospective pleasure and pain are severally the only good (...) reasons for action. ‘Pleasure’, ‘enjoyment’, and ‘being pleased’ are three graces that stand at the intersection of psychology, axiology, and practical reasoning. The relation between pleasure and awareness or consciousness of pleasure is subtle and unlike the corresponding relation to having a pain. To live the life of a practical hedonist is to live a life guided by the pursuit of pleasure. (shrink)

This article extends Aron Gurwitsch’s ( 1964 ) central insight about the field of consciousness—that it is always organized in a theme, thematic field, margin pattern—to the human capacity for reverence. It offers an original phenomenology of reverent awe, inspired by Gurwitsch’s work, as an articulation of reverential index and reverential attitude. According to Paul Woodruff ( 2014 ) in Reverence: Renewing a Forgotten Virtue, reverence names those times when we become aware of something larger than human and simultaneously our (...) human limitations. By bridging the concepts of reverence from Woodruff and relevancy from Gurwitsch, this study shows that in reverent awe the emphasis in consciousness shifts to the edge of relevancy, the zones farthest removed from the theme, as the “indefinite continuation of context,” “order of existence,” or what Gurwitsch also calls an “inarticulate mass”. Reverent awe is clarified phenomenologically as an emphasis in consciousness between the theme and the order of existence as indefinite continuation of thematic context, maintaining a specific relevancy-principle (a Gestalt-connection) between the theme and the order of existence. In a reverential attitude with a reverential index we become aware more immediately of an order of existence and we become aware of our place in the order of existence. (shrink)

Striving to find a simple characterization of the essence of the imagination, philosophers have argued that it consists in the power to call up before the mind mental images, either in recollection and recognition or in fancy. Wittgenstein's interest in the imagination focused upon six interrelated themes. First, the concept of imagination is associated with the concept of a mental image. Second, imagination is connected in various ways with perception. Third, the faculty of imagination is associated with artistic creativity and (...) no less so with intellectual creativity, with originality, insight and deviation from stock solutions to problems. Fourth, 'to imagine' is connected not only with intellectual creativity, but also more generally with thought, conception or supposition. Fifth, 'to imagine' is associated with false belief, mistaken memory and misperception. Finally, the imagination is connected with make‐believe, pretence, play‐acting or idle fancy. The multitude of grammatical similarities between the visual imagination and visual perception is deceptive. (shrink)

Upshot: Time constraints, locked curriculums, strict management, and possible anarchy in the classroom are some of the themes that originated from the commentaries. I argue that these challenges should be viewed holistically in the broader picture. I also question the educator’s role in mitigating these obstacles. My advice: Do it anyway.

Debates about Catholic social doctrine often revolve around whether a given theory or practice is compatible with the magisterium or not. There is a body of scholarly literature on the nature and scope of the magisterium, but little has been written on the magisterium as it pertains to social doctrine. This essay explores what magisterial documents and scholarship say about the sources, levels, and scope of the magisterium in relation to social doctrine. It then considers how the levels of magisterium (...) can help the faithful understand contemporary teaching on capital punishment. The better they understand the magisterium in relation to social doctrine, the more charitable and fruitful debate will be. (shrink)

The physical world consists of relatively enduring objects that exist in an objective spatiotemporal framework, that consist of matter of one kind or another, and that interact with each other in physical processes and events. In the course of his reflections on the idea of a private language, and more generally in his ruminations on psychology and the philosophy of psychology, Wittgenstein subjected the traditional philosophical picture to critical scrutiny. In every respect he found it a distortion of grammar in (...) the flawed mirror of metaphysics. The concept of pain‐location is parasitic on the concept of the sufferer from pain, for the location of a pain is where the sufferer points and where he avows it is. Frege presented the idea that pains (experiences in general) are inalienably owned by the person whose pains or experiences they are as a metaphysical insight into the essential nature of things.

In reviewing Ellis' OCT of Catullus, Housman scorned the ‘diction and metre’ of Carm. 64.37, ‘Pharsaliam coeunt, Pharsalia tecta frequentant’. Yet several subsequent editors have agreed with Ellis and have also refrained from emending Pharsaliam. Even if there has not been enough discomfort with the MS reading to put some editors off retaining it, they might yet welcome a piece of positive evidence to support this decision. I will make the case that a passage in Statius' Achilleid may indicate that (...) the later poet was familiar with the line as the MSS have it. (shrink)
