No single theory so far proposed gives a wholly satisfactory account of the origin and maintenance of bird-song dialects. This failure is the consequence of a weak comparative literature that precludes careful comparisons among species or studies, and of the complexity of the issues involved. Complexity arises because dialects seem to bear upon a wide range of features in the life history of bird species. We give an account of the principal issues in bird-song dialects: evolution of vocal learning, experimental (...) findings on song ontogeny, dialect descriptions, female and male reactions to differences in dialect, and population genetics and dispersal.We present a synthetic theory of the origin and maintenance of song dialects, one that accommodates most of the different systems reported in the literature. The few data available suggest that large, regional dialect populations are genetically differentiated; this pattern is correlated with reduced dispersal between dialects, assortative mating by females, and male-male exclusion. At the same time, “subdialects” may be formed within regional dialects. Subdialect clusters are usually small and may represent vocal mimicry among a few adjacent territorial males. The relative importance of genetic and social adaptation may contribute to the emergence of subdialects; their distinctiveness may be correlated with the degree of polygyny, for example. Thus, subdialect formation is linked to one theory of the evolution of repertoire size, but data are too fragmentary to examine this idea critically. (shrink)

No serious scholar in Christian Social Ethics today can introduce students to his or her field without taking into account the contributions of African American scholarship. The long traditions of Christian Social Ethics in the black church, and the innovative research and writing performed by African-American scholars in recent years are now essential components of a critical study of Ethics. Yet up to now, knowing how best to introduce the fruits of African American ethical scholarship to students, particularly those in (...) the survey class, has been difficult. Good resources exist, yet too often they were not written with the needs of introductory students in mind. This book meets that need by providing an overview of the most important developments in African American approaches to Christian Social Ethics. Written with the needs of beginning students in mind, it will offer insight into the particular ways that African American scholarship has shaped the world of Christian Ethics. (shrink)

The recently proposed ``infinite decision puzzle'' is based on incorrect mathematics.

Some claim that cognitive science of religion (CSR) either completely “explains religion away,” or at the very least calls the epistemic status of religious belief into question. Others claim that religious beliefs are the cognitive outputs of systems that seem highly reliable in other contexts, and thus CSR provides positive epistemic support for religious belief. I argue that (i) CSR does not provide evidence for atheism, but (ii) if one is an atheist, CSR lends “intellectual aid and comfort,” (iii) CSR (...) does not provide evidence for theism, but (iv) if one is a theist, CSR provides qualified support for Reformed Epistemology.

In a recent paper, Guy Kahane asks whether God’s existence is something we should want to be true. Expanding on some cryptic remarks from Thomas Nagel, Kahane’s informative and wide-ranging piece eventually addresses whether personal anti-theism is justified, where personal anti-theism is the view that God’s existence would make things worse overall for oneself. In what follows, I develop, defend, but ultimately reject the Meaningful Life Argument, according to which if God’s existence precludes the realization of certain goods that seem (...) to an agent to constitute a meaningful life, it is rational for an agent both to believe that personal anti-theism is true and to prefer that God not exist.

Selon Kirk Lougheed, favoriser une version objective de l’argument du sens de la vie établit une sorte d’antithéisme, c’est-à-dire une perspective qui maintient que l’existence d’un Dieu théiste aggraverait les choses et qu’il est donc plus rationnel de préférer que Dieu n’existe pas. Cette version objective est présentée par Lougheed comme une amélioration par rapport à ma version subjective de l’argument du sens de la vie. Je soutiens que la version de Lougheed ne réussit pas mieux que la version subjective (...) que j’ai développée, puis rejetée. (shrink)

The attempt to relate distinctions in perceptual theory to different physiological systems leads to numerous exceptions and inconsistencies. A more promising approach to the reconciliation of constructivist theory and direct perception is to recognize that perception does involve inference, as the constructivists insist, but that inference is a process in logic that does not require unconscious reasoning and need be no more thought-like than resonance.

At the Second Annual Meeting of the New York University Institute of Philosophy convened to consider the scientific status of psychoanalysis, Professor John Hospers was one of the few participating philosophers who undertook to defend the scientific status of psychoanalysis against the cogent criticisms of his fellow philosophers. In this paper I shall examine Hospers’ defense, “Philosophy and Psychoanalysis”, as it appears in the published proceedings of the meeting [12] and in the process of so doing I shall attempt to (...) demonstrate that Hospers misunderstood the critique of his opponents, argued invalidly on several crucial issues and neglected to take into account the possibility of alternative explanations.

Pro-theism is the view that God’s existence would be good in that God’s existence increases the value of a world. Anti-theism is the view that God’s existence would decrease the value of a world. We develop and defend the morally good agent argument for pro-theism. The basic idea is that morally good agents tend to add value to states of affairs, and God, moral agent par excellence is no exception. Thus, we argue that the existence of God would be, on (...) balance, a good thing and therefore something that one can rationally desire to be true. (shrink)

Bradley N. Seeman charges that my book, The End of Apologetics: Christian Witness in a Postmodern Context, tends toward “the idolatry of linguistic license.” I point out some ways this runs against the text of the book and then outline a Wittgensteinian approach to language and truth that is alethically “quasi-realist.” On this view truth is both epistemic, or deflationary, in the sense that it depends upon assertability conditions for its truth values, while there is also a nonepistemic, realist component (...) to truth in that these assertability conditions derive from forms of life that involve precognitive involvement with extralinguistic affairs.

This paper examines an important issue facing academia-pay inversion. It discusses how inversion is accompanied by ethical issues including secrecy, moral dilemmas for faculty, honesty, and keeping promises. It then examines this issue from five ethical viewpoints: a legalistic perspective, ethical egoism, utilitarianism, distributive justice, and Kants deontological approach. As part of the discussion, the effect of the moral philosophy on the universitys corporate culture is examined, with attention given to morale and productivity. Finally, alternatives to pay inversion that universities (...) may want to consider are discussed. (shrink)
