David Kellogg Lewis (1941-2001) was one of the most influential philosophers of the twentieth century. He made significant contributions to almost every area of analytic philosophy including metaphysics, philosophy of language, philosophy of mind, and philosophy of science, and set the agenda for various debates in these areas which carry on to this day. In several respects he remains a contemporary figure, yet enough time has now passed for historians of philosophy to begin to study his place in twentieth (...) century thought. His philosophy was constructed and refined not just through his published writing, but also crucially through his life-long correspondence with fellow philosophers, including leading figures such as D.M. Armstrong, Saul Kripke, W.V. Quine, J.J.C. Smart, and Peter van Inwagen. His letters formed the undercurrent of his published work and became the medium through which he proposed many of his well-known theories and discussed a range of philosophical topics in depth. A selection of his vast correspondence over a 40-year period is presented here across two volumes. The letters offer an organic story of the origins, development, breadth, and depth of his philosophy in its historical context, as well as a glimpse into the influence of his many interlocutors."-- OCLC OLUC.

Refutes the methodological separatists who hold that the logic of explanation and testing in the human sciences is fundamentally different than in the natural sciences, and develops complementary accounts for interpretation and explanation, ...

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

This volume is devoted to Lewis's work in ethics and social philosophy. Topics covered include the logic of obligation and permission; decision theory and its relation to the idea that beliefs might play the motivating role of desires; a subjectivist analysis of value; dilemmas in virtue ethics; the problem of evil; problems about self-prediction; social coordination, linguistic and otherwise; alleged duties to rescue distant strangers; toleration as a tacit treaty; nuclear warfare; and punishment. This collection, and the two preceding volumes, (...) will disseminate more widely the work of an eminent and influential contemporary philosopher. (shrink)

The void is deadly. If you were cast into a void, it would cause you to die in just a few minutes. It would suck the air from your lungs. It would boil your blood. It would drain the warmth from your body. And it would inflate enclosures in your body until they burst}.

This book is a product of the cultural, economic, political, and social environments during the early and mid-1990s in the United States. Designed for media consumers as well as future practitioners, it illustrates the actual and potential social consequences of the media, and media theory and research. Today, some mass communication programs are offering advanced undergraduate classes in an effort to appeal to the widespread interest in mass communication issues among students in all majors. This text, with its emphasis on (...) research concerning topics such as public opinion and the impact of media violence, is intended to fit in well with those efforts. (shrink)

Cicero, Lucullus 38: ‘…non potest animal ullum non adpetere id quod accommodatum ad naturam adpareat …’ From earliest childhood every man wants to possess something. One man collects horses. Another wants gold. Socrates has a passion for companions. He would rather have a good friend than a quail or a rooster. In this way, Socrates begins his interrogation of Menexenus. He then congratulates Menexenus and Lysis for each having what he himself still does not possess. How is it that one (...) gets a friend, Socrates asks? Since the nineteenth century many who have read these lines have found them repulsive. Scholars have damned the Lysis for its selfish egoism, for regarding persons as personal belongings. At the turn of the century some sought to discredit the dialogue as a forgery and a calumny. Others debated the dating of the dialogue as Socratic or Platonic, seeking whom to blame rather than whom to credit. And those who have regarded the dialogue as Platonic have tried to redeem it by detecting hints of Plato's theory of Forms. A few have attempted to salvage reputations by understanding the argument of the Lysis as a reductio of egoism, or else by invoking the loyalty of Socrates' friends and the history of Plato's friendship for Dion of Syracuse to speak up for their defence. Guthrie has condemned the dialogue as a failure of method and presentation , and Vlastos has pronounced it a failure of love: ‘The lover Socrates has in view seems positively incapable of loving others for their own sake, else why must he feel no affection for anyone whose good-producing qualities he did not happen to need?’ The Lysis appears to make no positive contribution to the Greek tradition on friendship when compared to the Symposium or the Phaedrus. And in the subsequent tradition, whatever Aristotle might have borrowed from the dialogue he uses for his own purposes. Aristotle too is quite critical of specific points raised in the Lysis. Now it might seem that Aristotle made a place for the selfish love of the Lysis in his own theory, as an inferior grade of utility love. But even this cannot be so, if we are to agree with recent studies of Aristotle's ethics. According to Aristotle, if a client is friendly to his benefactor because of the latter's usefulness, this utilitarian motive must accompany a genuine concern for the benefactor's own interest in that relation, if they are to be friends. Inferior and genuine friendship may differ in purpose but not in regard for the well-being of the beloved. This respect for the object of one's love has no parallel in the Lysis, according to the standard reading of the dialogue. (shrink)

Despite criticism that dignity is a vague and slippery concept, a number of international guidelines on bioethics have cautioned against research that is contrary to human dignity, with reference specifically to genetic technology. What is the connection between genetic research and human dignity? In this article, I investigate the concept of human dignity in its various historical forms, and examine its status as a moral concept. Unlike Kant's ideal concept of human dignity, the empirical or relational concept takes human dignity (...) as something that is affected by one's circumstances and what others do. I argue that the dignity objection to some forms of genetic research rests on a view of human nature that gives humans a special status in nature – one that is threatened by the potential of genetic research to reduce individuals to their genetic endowment. I distinguish two main philosophical accounts of human nature. One of these, the Aristotelian view, is compatible with the use of genetic technology to help humans realize their inherent potential to a fuller extent. (shrink)

This is an introduction to a special volume of the journal, Philosophy in the Contemporary World, on "War, Peace, and Ethics" which contains ten original essays on a wide range of topics.

This article employs a sociological analysis of the changing role and mission of higher education from that of a ?public good? to that of a service industry. In this regard, the rise of modern universities as corporate enterprises in the recent decades has often neglected the important dimension of education as a process of enlightenment, with its ethical and moral dimensions. The author tries to put into perspective the relevance of searching for an ?ethical university? by proposing to integrate the (...) important notion of Enlightenment as formulated by Kant, Newman's idea of the university and other similar western ideals, with the eastern ideas of the Confucian Classic The Great Learning, in order to suggest how the quest for an ?ethical university? might materialize in the future.

Counterfactuals is David Lewis's forceful presentation of and sustained argument for a particular view about propositions which express contrary-to-fact conditionals, including his famous defense of realism about possible worlds. Since its original publication in 1973, it has become a classic of contemporary philosophy, and is essential reading for anyone interested in the logic and metaphysics of counterfactuals. The book also includes an appendix of related writings by Lewis.

This paper seeks to reconstruct the role of schooling in a moment of accelerated social, political, economic, geo-political, climatic, indeed planetary crisis. It identifies the school as a potentially prefigurative institution, an evolutionary social frontier, capable of nurturing the democratic social character, a form of sensibility apart from which authentic political democracy is not possible. As theorized by Herbert Marcuse and Richard Hart and Antonio Negri, the “new sensibility” or “multitude” is characterized by greater psychological freedom, individuality, social creativity and (...) self-rule, comprising a “whole of singularities” that “acts in common”. It suggests a human subject with a vital, biological drive for liberation, with a consciousness capable of breaking through the material as well as ideological veil of a society based on hierarchy and domination, and is associated politically with democracy and social-anarchism, or what Murray Bookchin called “communalism”. This paper identifies three main characteristics of an institution informed by this form of modal subjectivity, all of them based on student-teacher dialogue: an emergent, project-based curriculum, whole-school direct democratic governance on all levels of the community, and the regular practice of communal philosophical inquiry, through which we problematize the concepts we live by, in the interest of their ongoing reconstruction.

The mammalian blastocyst exhibits a high capacity for aerobic glycolysis, a metabolic characteristic of tumours. It has been considered that aerobic glycolysis is a means to ensure a high carbon flux to fulfil biosynthetic demands. Here, alternative explanations for this pattern of metabolism are considered. Lactate creates a microenvironment of low pH around the embryo to assist the disaggregation of uterine tissues to facilitate trophoblast invasion. Further it is proposed that lactate acts as a signalling molecule (especially at the reduced (...) oxygen tension present at implantation) to elicit bioactive VEGF recruitment from uterine cells, to promote angiogenesis. Finally it is suggested that the region of high lactate/low pH created by the blastocyst modulates the activity of the local immune response, helping to create immune tolerance. Consequently, the mammalian blastocyst offers a model to study the role of microenvironments, and how metabolites and pH are used in signalling. (shrink)

This article examines the Basotho’s views on sexuality within a theological context as wellas the conflict between Christianity and cultural beliefs. Most Basotho have strong opinions on the subject of sexuality and those views undoubtedly emanate from the Basotho culture,which makes it necessary to evaluate them. The issue of sexuality is always a topic of discussion amongst people and did not go unnoticed by church fathers, like Augustine. Thomas Aquinas also expressed an interest in the topic in the Middle-Ages. Likewise, (...) reformers of the calibre of Martin Luther and John Calvin espoused views on sexuality. Itis clear that the aforementioned theologians made a marked contribution toward shapingthe current views on sexuality, especially amongst theologians of this age and this is thereason for revisiting their views in this article examining the Basotho view on sexuality.In examining Basotho views on sexuality, the writer of this article will then discuss andevaluate the views of Augustine, Aquinas, Luther and Calvin with special reference tosexual intercourse, sexual intercourse within matrimony, extramarital sexual intercourseand also the unmarried state.

The aim of the paper is to show that there are actions which are non-intentional. An account is first given which links intentional and unintentional action to acting for a reason, or appropriate causation by an intention. Mannerisms and habitual actions are then presented as examples of behavior which are actions, but which are not done in the course of acting for a reason. This account has advantages over that of Hursthouse's "arational actions," which are allegedly intentional actions done for (...) no reason at all. Finally, one consequence of neglecting non-intentional action is discussed to illustrate its importance. (shrink)

Mental models theorists have proposed that reasoners tend to focus on what is explicit in their mental models, and that certain debiasing procedures can induce them to direct their attention to other relevant information. For instance, Green and Larking 1995; also Green, 1995a facilitated performance on the Wason selection task by inducing participants to consider counterexamples to the conditional rule. However, these authors acknowledged that one aspect of their data might require some modification to the mental models theory. This research (...) is discussed here, and it is suggested that the results may be better accommodated by mental inference rules theory than by mental models theory. (shrink)

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly. It may be analyzed in terms of similarity of worlds, As follows: "in the fiction f, A" means that a is true in those of the worlds where f is told as known fact rather than fiction that differ least from our world, Or from the belief worlds of the community in (...) which the fiction originated.
