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)

The knowledge account of assertion holds that it is improper to assert that p unless the speaker knows that p. This paper argues against the knowledge account of assertion; there is no general norm that the speaker must know what she asserts. I argue that there are cases in which it can be entirely proper to assert something that you do not know. In addition, it is possible to explain the cases that motivate the knowledge account by postulating a general (...) norm that assertions would be true, combined with conversational norms that govern all speech acts. A theory on which proper assertions must be true explains the data better than a theory on which proper assertions must be known to be true. (shrink)

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)

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)

For many species that reproduce sexually, how sex is expressed at different points across lifespan is highly contingent and dependent on various environmental factors. For example, in many species of fish, environmental cues can trigger a natural process of sex transition where a female transitions to male. For many species of turtle, incubation temperature influences the likelihood that turtle eggs will hatch males or females. What is the case for Homo sapiens? Is human sex expression influenced by contingent environmental factors (...) like we see in fish and turtles, with whom we share common ancestry and DNA? Our paper explores the current biological science of sex determination and how it applies to philosophical and theological accounts of the human person. We argue that while human sex determination is not susceptible to environmental cues to the same degree we see in other species, there is sufficient variability among the pathways of human sex development to complicate simplistic biological categories of male and female.

Not only can the influence of Gottlob Frege be found in contemporary work in logic, the philosophy of mathematics, and the philosophy of language, but his projects—and the very terminology he employed in pursuing those projects—are still current in contemporary philosophy. This is undoubtedly why it seems so reasonable to assume that we can read Frege' s writings as if he were one of us, speaking to our philosophical concerns in our language. In Joan Weiner's view, however, Frege's words (...) can be accurately interpreted only if we set that assumption aside. Weiner here offers a challenging new approach to the philosophy of this central figure in analytic philosophy. Weiner finds in Frege's corpus, from Begriffsschrift on, a unified project of remarkable ambition to which each of the writings in that corpus makes a distinct contribution—a project whose motivation she brings to life through a careful reading of his Foundations of Arithmetic. The Frege that Weiner brings into clear view is very different from the familiar figure. Far from having originated one of the standard positions on the nature of reference, Frege turns out not to have had positive doctrines on anything like what contemporary philosophers mean by "reference." Far from having served as a standard-bearer for those who take the realists' side of contemporary disputes with anti-realists, Frege turns out to have had no stake in either side of the controversy. Through Weiner's lens, Frege emerges as a thinker who has principled reasons for challenging the very assumptions and motivations that animate philosophers to dispute these doctrines. This lucidly written and accessible book will generate controversy among all readers with an interest in epistemology, philosophy of language, history of philosophy, and the philosophy of mathematics.

We suggest a rigorous theory of how objective single-case transition probabilities fit into our world. The theory combines indeterminism and relativity in the “branching space–times” pattern, and relies on the existing theory of causae causantes (originating causes). Its fundamental suggestion is that (at least in simple cases) the probabilities of all transitions can be computed from the basic probabilities attributed individually to their originating causes. The theory explains when and how one can reasonably infer from the probabilities of one “chance (...) set-up” to the probabilities of another such set-up that is located far away. (shrink)

Recently attention has been paid to the epistemic requirements for proper assertion. The most popular account has been the knowledge account, that we can only properly assert what we know. Others have criticized the knowledge account and argued that the norm of assertion is truth, belief, or assertion of what it is reasonable to believe.

Klaas J. Kraay argues that the rational choice model for divine creation—according to which God chooses to actualize one world among possible alternatives based on its axiological properties—cannot succeed given failures of comparability across possible worlds. I argue that failure of comparability across worlds would not undermine the rationality of choosing one world to create among possible alternatives.

Bradley N. Seeman has argued that The End of Apologetics comes perilously close to what he calls “the idolatry of linguistic license.” Despite my recent reply, Seeman continues to have a few concerns about my position. I offer a clarification regarding my description of theological language as “poetics,” and argue that it is a way of acknowledging the contingency of all theological descriptions and vocabularies. I also counter Seeman’s insistence on trans-language game truth-makers by noting that it begs the central (...) issue of my “alethic quasi realism,” and argue that this is not a thoroughly deflated concept of truth.

SummaryBy now, the story of T. D. Lysenko's phantasmagoric career in the Soviet life sciences is widely familiar. While Lysenko's attempts to identify I. V. Michurin, the horticulturist, as the source of his own inductionist ideas about heredity are recognized as a gambit calculated to enhance his legitimacy, the real roots of those ideas are still shrouded in mystery. This paper suggests those roots may be found in a tradition in Russian biology that stretches back to the 1840s—a tradition inspired (...) by the doctrines of Jean-Baptiste Lamarck and Etienne and Isidore Geoffroy Saint-Hilaire. The enthusiastic reception of those doctrines in Russia and of their practical application—acclimatization of exotic life forms—gave rise to the durable scientific preoccupation with transforming nature which now seems implicated in creating the context for Lysenko's successful bid to become an arbiter of the biological sciences.

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.

Preview: /Review: Tommy Shelby and Brandon M. Terry, eds. To Shape a New World: Essays on the Political Philosophy of Martin Luther King, Jr., 463 pages./ To mark the fiftieth anniversary of Martin Luther King, Jr.’s assassination, Harvard professors Tommie Shelby and Brandon M. Terry have produced a masterful reappraisal of King’s legacy, specifically as a political philosopher. More importantly, the book can be read as a mirror through which we can see King’s struggles and resistance, that led him down (...) a “dangerous road,” having strong parallels with the dangerous road we face with current political and social upheavals. Negative reactions against globalization have heightened the sentiments of fear, paranoia, and partisanship. Racial tensions are reaching a boiling-point in the U.S. after the 2017 Charlottesville protests and a pattern of discrimination and senseless killings from the privileged campus of Yale to the country roads of Minnesota or Georgia, by law enforcement and civilians alike. One of the tendencies growing in this distressing hour of world history entails the rise of personality and celebrity cults forming around “strong” leaders. A mobocracy mentality is forming the way we think about politicians, judges, or even health specialists like chief U.S. immunologist Anthony Fauci. Celebrity fetishizing has infected Americans’ sense of reality, including the ways in which politics are practiced and interpreted. Engulfed in the quagmires of identity politics, our attempts to legitimate who has the right to fight for social justice have been paralyzed by these performative gestures of social change and action. It could be argued that the aesthetic presentation and the skills of rebranding have, in a certain sense, replaced the philosophical and moral concerns explored in the sections on “Traditions,” “Ideals,” “Justice,” and “Conscience,” respectively. What King teaches us philosophically has, more often than not, been glossed over by a superficial publicity or aesthetics of infotainment destined for the tabloids. For this reason, King’s iconic image is both a blessing and curse. In order to appreciate the full thrust of King’s thinking, we have to go deeper morally and philosophically to supplement our aesthetic religious values and interests, and that is what these fifteen essays deliver.

Cultural identities and rituals are intersecting through increasingly overlapping social worlds. Whether one chooses to join in this mixing and to what degree, that is the question. Appropriationists and assimilationists assume a logic of domination that aims to justify forms of social entitlement, claiming exclusive possession or ownership of cultural heritages. This article argues that cultural adoption is a stronger frame for understanding how circulation of rituals and practices get distributed under “liquid,” orphan-like conditions. By accepting that no stable centers (...) or margins of culture can be securely ascertained, new semiotics of integral fakes gain cultural efficacy. Integral fakes manifest semblances and likenesses that can be adopted as one’s own, intensifying our experience of cultural freedom by expanding our sense of the familiar into unfamiliar cultural scales. Through a semiotics of cultural adoption, we hope to be attuned to an openness and hospitality that romanticized ideologies of culture suppress. (shrink)

One of the most intriguing and underappreciated aspects of Alfred North Whitehead’s philosophy is his treatment of peace as a civilizational aim of culture. The problem of peace is the subject in the final chapter of Whitehead’s Adventures of Ideas. It is considered along with the other four qualities of civilized societies, “Adventure, Art, Beauty, and Truth.” Although his analysis is driven by examples from Western and Christian history, respectively, the treatment of peace developed is not limited to this or (...) any specific experiential epoch. Peace is a transcultural value, the “harmony of harmonies,” which lies at the heart or in the “nature of things.” Whitehead designates the permanence-flux contrast of peace in human life as a tension between the “dream of youth” and “harvest of tragedy.” Our lives give way to the dance of the possible and actual that both unites and divides us. This article explains how Whitehead attempts to argue for peace by way of “balanced intensity” in response to the triumphs and tribulations of life. Section one deals with the ways in which youth and eros symbolize possibility and orient us toward the possible. Tragedy, or the determination of the individual in its own subjective realization and the consequent nature it produces through the “unity of adventure,” is the focus of the second section. In section three, the erotic-tragic contrast is presented in relation to peace as an “intuition of permanence.” In conclusion, Whitehead’s humanism will be offered as a viable alternative against the modern belief of progress or the quest for worldly success, in which prosperity becomes antithetical to the achievement of peace given its propensity to evade or outrun tragedy.

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.
