Sewall Wright and Gustave Malécot developed important theories of isolation by distance. Wright’s theory was statistical and Malécot’s probabilistic. Because of this mathematical difference, they were not clear about the relationship between their theories. In this paper, I make two points to clarify this relationship. First, I argue that Wright’s theory concerns what I call ecological isolation by distance , whereas Malécot’s concerns what I call genetic isolation by distance . Second, I suggest that if Wright’s theory is interpreted appropriately, (...) a previously unnoticed connection between the two theories emerges. †To contact the author, please write to: Yoichi Ishida, Department of History and Philosophy of Science, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e‐mail: [email protected].

The construct of Cognitive Moral Development (CMD) has drawn much attention in the study of business ethics for over two decades. The Defining Issues Test (DIT) has made a significant contribution to the literature as an easy-to-administer CMD instrument, and the Moral Judgment Test (MJT), an alternative scale, has also been used widely especially in Europe. The two scales differ in their approaches to measuring CMD, focusing on stage preference (DIT) and stage consistency (MJT), yet empirical comparisons have been scarce. (...) The present research empirically compares the two scales in terms of their correspondence with ethical ideology as a reference scale, and it demonstrates a clear distinction between the DIT and the MJT. Although they both aim to measure CMD, their dissimilar approaches lead to distinctly different implications. (shrink)

What is the morally significant feature of discrimination? All of the following seem plausible – (i) discrimination is a kind of wrongdoing and it wrongs discriminatees, which is a matter of intrapersonal morality; (ii) in view of cases of indirect discrimination, significant normative features of discrimination are best captured in a discriminatee‐focused, or harm‐based, way; and (iii) discrimination, as an act‐type, necessarily involves interpersonal comparison. The first task of this article is to address which of intra‐ or interpersonal comparison is (...) relevant to philosophical questions concerning discrimination. I submit that each of them has a place in the theory of discrimination; while interpersonal comparison is relevant in determining whether a differentiating act counts as discrimination, intrapersonal comparison is relevant in assessing whether it is morally wrong. The second task is to develop further a harm‐based answer to the latter question. My final proposal is as follows: discrimination is pro tanto morally wrong to the extent that it makes the discriminatees worse off than they would be were it not for the discrimination at issue, where one's well‐being is understood in terms of what one endorses in one's optimum form.

Following a science and ontology conference in Barbizon, France, Layla Raïd and Karim Belabas published an article on Peirce and Quine that focuses on truth considered as the convergence of opinions or theories. 2 The article is a productive collaboration between a philosopher and mathematician, identifying two problems that Quine poses: first, the use of numerical analogy in Peirce’s account of truth, and second, the uniqueness of the final opinion, which can presumably be defeated or undermined by arguments from underdetermination (...) of theories. 3 I accept their interpretation insofar as these two problems are considered to constitute main issues for those—including myself—who wish to advocate Peirce’s view, but..

Robert MacArthur's mathematical ecology is often regarded as ahistorical and has been criticized by historically oriented ecologists and philosophers for ignoring the importance of history. I clarify and defend his approach, especially his use of simple mathematical models to explain patterns in data and to generate predictions that stimulate empirical research. First I argue that it is misleading to call his approach ahistorical because it is not against historical explanation. Next I distinguish three kinds of criticism of his approach and (...) argue that his approach is compatible with the first two of them. Finally, I argue that the third kind of criticism, advanced by Kim Sterelny and Paul Griffiths, is largely irrelevant to MacArthur's approach. ‡I am especially grateful to Thomas Nickles for encouragement and helpful comments on earlier versions of this paper. Thanks also to Guy Hoelzer, Stephen Jenkins, and Jay Odenbaugh for comments on an earlier draft, Kim Sterelny for clarifications of the Tasmania example, Gregory Mikkelson for references, and the audience at PSA 2006 for discussions. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e-mail: [email protected].

The Christian philosopher Muto Kazuo contributed substantially to the predominantly Buddhist “Kyoto School of Philosophy.” Through critical exchange with its representatives, he opened up new perceptions of Christian faith, enabled mutual understanding between Buddhism and Christianity, and challenged the Western dialectical method.

In the history of Indian Buddhism there existed scholars, who engaged in studying logic and epistemology, and this tradition still survives e.g. in Tibet. This field of study was traditionally called “the study of the logical reason” (hetuvidyā), and this school was named “die logische und erkenntnistheoretische Schule des Buddhismus” (the Buddhist logico-epistemological tradition) by Prof. Erich Frauwallner. These scholars actually developed full-blown theories of logic and epistemology and were actively involved in discussions with Buddhist as well as non-Buddhist philosophers. (...) Nowadays the research of this school forms one of the major fields in the Indian Philosophy and Buddhist studies. However, it is still controversial among the modern scholars, as was the case with the historicalteachers in India and Tibet, whether this study of logic or epistemology is of any relevance for the Buddhist striving for liberation (nirvāna). In this presentation I would like to focus on discussing the status of scriptural authority in this tradition, and especially the interpretations of one statement by Dignāga (ca. 400-480), who is regarded as founder of the Buddhist logico-epistemological tradition, will be re-examined.

We consider a spatial bargaining model where players collectively choose a facility location on a two-dimensional rectilinear distance space through bargaining using the unanimity rule. We show that as players become infinitely patient, their stationary subgame perfect equilibrium utilities converge to the utilities that satisfy the lexicographic maximin utility criterion introduced by Sen.

Fuzzy logic has become an important tool for a number of different applications ranging from the control of engineering systems to artificial intelligence. In this concise introduction, the author presents a succinct guide to the basic ideas of fuzzy logic, fuzzy sets, fuzzy relations, and fuzzy reasoning, and shows how they may be applied. The book culminates in a chapter which describes fuzzy logic control: the design of intelligent control systems using fuzzy if-then rules which make use of human knowledge (...) and experience to behave in a manner similar to a human controller. Throughout, the level of mathematical knowledge required is kept basic and the concepts are illustrated with numerous diagrams to aid in comprehension. As a result, all those curious to know more about fuzzy concepts and their real-world application will find this a good place to start. (shrink)

Welfare subjectivists face a dilemma. On the one hand, traditional subjectivist theories—such as the desire-fulfillment theory—are too permissive to account for the well-being of typical mature human beings. On the other hand, more “refined” theories—such as the life-satisfaction theory—are too restrictive to account for the well-being of various welfare subjects, including newborns, those with profound cognitive impairments, or non-human animals. This paper examines a class of welfare subjectivism that addresses this dilemma with sensitivity to the diversity in welfare subjects. First, (...) the most-sophisticated-attitude view (MSA) is introduced. MSA holds that an object, $$x$$ x, is good for a subject, $$S$$ S, in proportion to the strength of $$S$$ S ’s pro-attitude towards $$x$$ x if and only if the pro-attitude at issue is $$S$$ S ’s most sophisticated type. Typically, the well-being of typical mature human beings is assessed in terms of one’s authentic whole-life satisfaction, whereas that of human newborns is assessed in terms of something less sophisticated such as pleasure. MSA offers the rationale for this difference based on an underexplored version of perfectionism: procedural perfectionism. Next, provided that MSA may involve an implausibly strong claim, this paper examines two moderate variations of MSA that accept the partial relevance of less sophisticated types of valenced attitude. Finally, it is illustrated how MSA and its variations have plausible implications regarding the well-being of enhanced or dis-enhanced people. (shrink)
