The unit of selection is the concept of that ‘something’ to which biologists refer when they speak of an adaptation as being ‘for the good of’ something. Darwin identified the organism as the unit of selection because for him the ‘struggle for existence’ was an issue among individuals. Later on it was suggested that, in order to understand the evolution of social behavior, it is necessary to argue that groups, and not individuals, are the units (...) of selection. The last addition to this debate was the formulation by Dawkins, in 1976, that the genes themselves are the units of selection while the organisms are merely the temporary receptacles and vehicles for such genes. Thus, the preposterous dissolution of the organism into genes and the proteins coded by such genes has been introduced in the evolutionary discourse by neglecting that the explanations for biological phenomena can be either synchronic or diachronic, depending on the phenomenon to be explained. Therefore explanations in molecular biology are synchronic while evolutionary biology needs diachronic explanations. Nevertheless, for ultra-Darwinians such as Dawkins, efficient replication is all that biology is about. Here I develop an argument in order to show that there is nothing in molecular and cell biology that might support such a contention and that the idea of the gene as the unit of selection is incompatible with the evident evolution of biological complexity.

This anthology collects some of the most important papers on what is believed to be the major force in evolution, natural selection. An issue of great consequence in the philosophy of biology concerns the levels at which, and the units upon which selection acts. In recent years, biologists and philosophers have published a large number of papers bearing on this subject. The papers selected for inclusion in this book are divided into three main sections covering the history of (...) the subject, explaining its conceptual foundations, and focusing on kin and group selection and higher levels of selection.One of the book's interesting features is that it draws together material from the biological and philosophical literatures. The philosophical literature, having thoroughly absorbed the biological material, now offers conceptual tools suitable for the reworking of the biological arguments. Although a full symbiosis has yet to develop, this anthology offers a unique resource for students in both biology and philosophy.Robert N. Brandon is Professor in the Philosophy Department, Duke University. Richard M.

The reductionistic vision of evolutionary theory, "the gene's eye view of evolution" is the dominant view among evolutionary biologists today. On this view, the gene is the only unit with sufficient stability to act as a unit of selection, with individuals and groups being more ephemeral units of function, but not of selection. This view is argued to be incorrect, on several grounds. The empirical and theoretical bases for the existence of higher-level units of (...) class='Hi'>selection are explored, and alternative analyses discussed critically. The success of a multi-level selection theory demands the recognition and development of a multi-level genetics. The way to accomplish this is suggested. The genotype/phenotype distinction also requires further analysis to see how it applies at higher levels of organization. This analysis provides a way of defining genotype and phenotype for cultural evolution, and a treatment of the innate-acquired distinction which are both generalizeable to analyze problems of the nature and focus of scientific change.

Natural selection is an important force that shapes the evolution of all living things by determining which individuals contribute the most descendents to future generations. The biological unit upon which selection acts has been the subject of serious debate, with reasonable arguments made on behalf of populations, individuals, individual phenotypic characters and, finally, individual genes themselves. In this essay, I argue that the usual unit of selection is the gene. There are powerful logical arguments in (...) favor of this conclusion, as well as many real-world examples. I also explore the possibility that epigenetic differences between individuals may be heritable between generations. Although few such examples exist, epigenetic differences provide an exciting source of potentially heritable variation that may allow rapid evolutionary change to occur, perhaps in response to environmental influences.

Doctoral programs at U.S. universities play a critical role in the development of human resources both in the United States and abroad. This volume reports the results of an extensive study of U.S. research-doctorate programs in five broad fields: physical sciences and mathematics, engineering, social and behavioral sciences, biological sciences, and the humanities. Research-Doctorate Programs in the United States documents changes that have taken place in the size, structure, and quality of doctoral education since the widely used 1982 editions. This (...) update provides selected information on nearly 4,000 doctoral programs in 41 subdisciplines at 274 doctorate-granting institutions. This volume also reports the results of the National Survey of Graduate Faculty, which polled a sample of faculty for their views on the scholarly quality of program faculty and the effectiveness of doctoral programs in preparing research scholars/scientists. This much-anticipated update of such an essential reference will be useful to education administrators, university faculty, and students seeking authoritative information on doctoral programs.

Genic selectionism holds that all selection can be understood as operating on particular genes. Critics (and conventional biological wisdom) insist that this misrepresents the actual causal structure of selective phenomena at higher levels of biological organization, but cannot convincingly defend this intuition. I argue that the real failing of genic selectionism is pragmatic – it prevents us from adopting the most efficient corpus of causal laws for predicting and intervening in the course of affairs – and I offer a (...) Pragmatic account of causation itself which ultimately bears out the claim that genic selectionism misrepresents the causal structure of selective contexts. (shrink)

The controversy regarding the unit of selection is fundamentally a dispute about what is the correct causal structure of the process of evolution by natural selection and its ontological commitments. By characterizing the process as consisting of two essential steps--interaction and transmission--a singular answer to the unit question becomes ambiguous. With such an account on hand, two recent defenses of competing units of selection are considered. Richard Dawkins maintains that the gene is the appropriate (...) class='Hi'>unit of selection and Robert Brandon, in response, argues that the individual organism is better suited to the role. This paper argues that by making explicit the underlying questions that each of these views addresses, the apparent conflict can be resolved. Furthermore, such a resolution allows for a more complete and realistic understanding of the process of evolution by natural selection. (shrink)

Most donated organs in the United States come from brain dead donors, while a small percentage come from patients who die in “controlled,” or expected, circumstances, typically after the family or surrogate makes a decision to withdraw life support. The number of organs available for transplant could be substantially if donations were permitted in “uncontrolled” circumstances–that is, from people who die unexpectedly, often outside the hospital. According to projections from the Institute of Medicine, establishing programs permitting “uncontrolled donation after circulatory (...) determination of death,” or uDCDD, throughout the United States has the potential to provide 22,000 more donation opportunities annually. In contrast, U.S. controlled donation after circulatory determination of death, or cDCDD, cases have increased progressively over the past decade from 87 to 848 donors, but currently account for only 10.6 percent of all deceased donors. Following the IOM recommendations, several projects exploring the feasibility of uDCDD were funded by the federal government, including a grant from the Health Resources and Services Administration that supported a pilot project in New York City in which the authors of this article participated.A key feature of our protocol, and indeed of many uDCDD protocols, is the initiation of preservation methods such as chest compressions and extracorporeal membrane oxygenation shortly after death in order to perfuse and preserve the donor's organs. Critics of uDCDD argue that the means of determining death deviates from generally ascribed principles. They assert that reinstituting circulation in order to preserve organs has the effect of “undoing” the prior determination of death. The result is that cDCDD is widely accepted and practiced routinely even though it only marginally increases the number of organs available for transplantation, and uDCDD is widely considered unacceptable despite being ethically embraced and proven to significantly increase organ donation opportunities in other countries. This article explores the evolution of this counterintuitive state of affairs and calls for a policy that, in line with the IOM report, allows for both cDCDD and uDCDD protocols. (shrink)

My general aim is to clarify the foundational difference between Stephen Jay Gould and Richard Dawkins concerning what biological entities are the units of selection in the process of evolution by natural selection. First, I recapitulate Gould’s central objection to Dawkins’s view that genes are the exclusive units of selection. According to Gould, it is absurd for Dawkins to think that genes are the exclusive units of selection when, after all, genes are not the exclusive interactors: (...) those agents directly engaged with, directly impacted by, environmental pressures. Second, I argue that Gould’s objection still goes through even when we take into consideration Sterelny and Kitcher’s defense of gene selectionism in their admirable paper “The Return of the Gene.” Third, I propose a strategy for defending Dawkins that I believe obviates Gould’s objection. Drawing upon Elisabeth Lloyd’s careful taxonomy of the various understandings of the unit of selection at play in the philosophy of biology literature, my proposal involves realizing that Dawkins endorses a different understanding of the unit of selection than Gould holds him to, an understanding that does not require genes to be the exclusive interactors.

Citizen petitions and legislative bills in seven states in the US have established space and movement limitations for selected species of farm animals. These actions show Americans becoming concerned about the humane treatment of confined farm animals, and willing to use governmental intervention to preclude existing confinement practices. The individual state provisions vary, including the coverage of species. All seven states deal with sow-gestation crates, five states address veal calf crates, and two states’ provisions also apply to battery cages (...) used for egg-laying hens. The actions show citizen and legislative opposition to current animal production practices, and suggest a movement to provide better treatment for farm animals. Accompanying the actions are challenges for animal production industries in remaining competitive while meeting social expectations on the ethical treatment of food animals. While the actions are only a small step in addressing welfare issues, they may be the beginning of a significant movement to do more to address human and animal welfare issues. (shrink)

The units of selection problem is an issue within evolutionary theory (or the philosophy thereof) and concerns the question of what units or objects are acted upon by natural selection -- for example, whether these are genes, organisms or groups of organisms. One of the central theses of Elliot Sober’s recent book, The Nature of Selection, is that the philosophical problem of what it means for something to be a unit of selection is to be (...) understood by applying the correct account of what it is in general for a factor to be a cause in a population.The account of population-causation that Sober utilizes for this purpose comes from the recent literature on probabilistic causality. This account requires that for C to cause E in a population, a unanimity condition must be satisfied: C must raise the probability of E in each causal context. (shrink)

The quality of doctoral-level biochemistry (N=139), botany (N=83), cellular/molecular biology (N=89), microbiology (N=134), physiology (N=101), and zoology (N=70) programs at United States universities was assessed, using 16 measures. These measures focused on variables related to: (1) program size; (2) characteristics of graduates; (3) reputational factors (scholarly quality of faculty, effectiveness of programs in educating research scholars/scientists, improvement in program quality during the last 5 years); (4) university library size; (5) research support; and (6) publication records. Chapter I discusses prior attempts (...) to assess quality in graduate education, development of the study plans, and the selection of disciplines and programs to be evaluated. Chapter II discusses the methodology used, focusing on each of the assessment measures. Chapters III to VIII present, respectively, findings from the analyses of the biochemistry, botany, cellular/molecular biology, microbiology, physiology, and zoology programs. Chapter IX includes a summary of results, correlations among measures, several additional analyses, and suggestions for future studies. Among the findings reported are those indicating that cellular/molecular biology programs had, on the average, the largest number of faculty and that students in cellular/molecular biology, biology, biochemistry, microbiology, and physiology received a relatively high fraction of financial support.

We all live our daily lives surrounded by the products of technology that make what we do simpler, faster, and more efficient. These are benefits we often just take for granted. But at the same time, as these products disburden us of unwanted tasks that consumed much time and effort in earlier eras, many of them also leave us more disengaged from our natural and even human surroundings. It is the task of what Gene Moriarty calls focal engineering to create (...) products that will achieve a balance between disburdenment and engagement: “How much disburdenment will be appropriate while still permitting an engagement that enriches one’s life, elevates the spirit, and calls forth a good life in a convivial society?” One of his examples of a focally engineered structure is the Golden Gate Bridge, which “draws people to it, enlivens and elevates the human spirit, and resonates with the world of its congenial setting. Humans, bridge, and world are in tune.” These values of engagement, enlivenment, and resonance are key to the normative approach Moriarty brings to the profession of engineering, which traditionally has focused mainly on technical measures of evaluation such as efficiency, productivity, objectivity, and precision. These measures, while important, look at the engineered product in a local and limited sense. But “from a broader perspective, what is locally benign may present serious moral problems,” undermining “social justice, environmental sustainability, and health and safety of affected parties.” It is this broader perspective that is championed by focal engineering, the subject of Part III of the book, which Moriarty contrasts with “modern” engineering in Part I and “pre-modern” engineering in Part II.

This paper aims to persuade its reader that libertarianism, at least in several of its varieties, is a species of the genus Michael Oakeshott referred to as ‘rationalism in politics’. I hope to demonstrate, employing the work of Oakeshott, as well as Aristotle and Onora O’Neill, how many libertarian theorists, who generally have a sincere and admirable commitment to personal liberty, have been led astray by the rationalist promise that we might be able to approach deductive certainty concerning the 'correctness' (...) of some political programme. Of course libertarians, in common with the adherents of almost any other political ‘stance’, are not a monolithic body, but exhibit a variety of more or less rationalist arguments for their views. For example, a thinker like Hayek, who is often placed in the libertarian camp, came to adopt much of Oakeshott’s critique of rationalism in his later work. And, of course, Oakeshott himself expressed an affinity for libertarian ideas in his essay, ‘The Political Economy of Freedom’ (1991 [1962]). But a general predilection to enhance individual freedom as far as is deemed practicable is quite a different matter from taking a stance in which liberty, and liberty conceived in a rather narrow fashion, is the only value deemed admissible into ‘reasonable’ political discourse. (We will see in a subsequent section that Oakeshott recognized this urge to sanctify one value above all others as a logical requirement of striving for deductive political truths.) I believe that a critique of such libertarian rationalism is particularly relevant given the present situation in the United States vis-à-vis civil rights and the ongoing ‘war on terror’, in that many non- libertarian supporters of peace and strong civil rights find themselves allied with libertarians on these issues—if libertarians have gotten these issues ‘correct’, then how might they have gone wrong elsewhere? Furthermore, the critique may aid libertarians themselves, because, if the title of this paper is accurate, such a single-minded exaltation of one value above all others is an enemy of true liberty, so that libertarians might want to rethink adopting such a position. As Philip Pettit demonstrates (1997), freedom as non-domination is more robust and inclusive of all that we value about freedom than is the libertarian concept of freedom as non-interference; by allowing, say, immense economic power to be concentrated in a single corporation, as intervention to break the company up would violate the principle of non-interference, libertarian ideas may greatly diminish the liberty of the people subject to that corporate power.

The usual interpretation of Republic 10 takes it as Socrates’ multilevel philosophical demonstration of the untruth and dangerousness of mimesis and its required excision from a well ordered polity. Such readings miss the play of the Platonic mimesis which has within it precisely ordered antistrophes which turn its oft remarked strophes perfectly around. First, this argument, famously concluding to the unreliability of image-makers for producing knowledge begins with two images—the mirror (596e) and the painter. I will show both undercut the (...) argument they introduce. Secondly, Socrates repeats the “three removes” argument three times. Each has its own object and philosophical axis. The “bed” argument (596a-598d) concerns the ontological status of images vis-à-vis human makers and the divine idea. The bit and bridle,” 601b-601d) emphasizes the epistemological status of image-making as beneath the human maker of bridles (having correct opinion) and the human user, who knows. This second takes away the ontological distinction which was the point of the first. Thus, any human being could be in any of the three positions—user, maker, imitator. This dance might bring one to doubt the conclusion that the imitator has “neither knowledge nor right opinion” (602a). Plato leads into his concluding psychological and moral argument (602c-605c) after a third variation of the 3 removes. This last gives us the image of the flute player (601d-602) as the one who knows and so can order the flute maker. We will conclude by considering what it is this flutist could know, and given that his art is itself a mimesis, who the imitator of this imitative artist could be. Thus attention to the differences among these examples opens a defense of the arts, which reverses many of the claims made against the arts within the ostensible “Platonic” argument. (shrink)

In the early 1970s, the major industrial states were preparing to shift to nuclear fission as their principal source of electrical power. But that change has not occurred. In part, this is due to a growing public recognition that techniques and institutions for management of spent nuclear fuel, separated plutonium, and long-lived radioactive wastes are not yet fully developed. The consequent pressures for resolution have spurred a series of often ill-defined and sometimes contradictory attempts to promote international cooperation and control (...) of hazardous activities. How are these varied suggestions to be compared and evaluated? By what criteria can plans be selected that are likely to be both effective and negotiable? In this study, Gene I. Rochlin, physicist and social scientist, explores the technical, political, and institutional aspects of international nuclear export and fuel cycle policies. He categorizes existing proposals and suggests way to develop new ones that better promote both national and international goals. Dr. Rochlin argues neither for nor against the use of nuclear power or plutonium fuels. Instead, he addresses the question of how international arrangements could be reached that might jointly satisfy the objective of the several key nations, yet not be too difficult to negotiate. He concludes that a major fault has been the tendency to improvise arrangements for specific technical or industrial operations. As a result, overall social and political goals have become the bargaining points for compromise. Yet attempts to simultaneously resolve all problems are unlikely to prove fruitful. Dr. Rochlin suggests instead the formation of institutions organized around more limited social, political, and technical objectives, even at the expense of excluding some nations or omitting some aspects of the nuclear fuel cycle. Only by so doing, he argues, can immediate agreements be reached that preserve the potential for more comprehensive future arrangements without sacrificing industrial, environmental, or nonproliferation goals. This important book will be of interest to scientists, social scientists, government officials, and others concerned with the problems of plutonium management and nuclear wastes. (shrink)

Imprecise definition of key terms in the “public participation” domain have hindered the conduct of good research and militated against the development and implementation of effective participation practices. In this article, we define key concepts in the domain: public communication, public consultation, and public participation. These concepts are differentiated according to the nature and flow of information between exercise sponsors and participants. According to such an information flow perspective, an exercise’s effectiveness may be ascertained by the efficiency with which full, (...) relevant information is elicited from all appropriate sources, transferred to all appropriate recipients, and combined to give an aggregate/consensual response. Key variables that may theoretically affect effectiveness—and on which engagement mechanisms differ—are identified and used to develop a typology of mechanisms. The resultant typology reveals four communication, six consultation, and four participation mechanism classes. Limitations to the typology are discussed, and future research needs identified.

Pamphilus’ introductory letter opens contradictory ways of reading Hume’s Dialogues. The first, suggested by Pamphilus' claim to be “mere auditor” to the dialogues, which were “deeply imprinted in [his] memory,” is the empiricist reading. This traditional reading could, and has, gone several ways, including to such conclusions as Philo forces upon Cleanthes, shocking Demea; e.g., that the design of the mosquito and other “curious artifices of nature,” which inflict pain and suffering on all, bespeaks an utterly careless and insensate, if (...) not malign creator. Pamphilus' preface also opens a more philosophical reading implied in his consideration of the ancient literary form of dialogue. This second interpretive path suspects more design in writing, and more revealed in it, than the simple empiricist reading(s) allow. Dialogically elucidating the Dialogues confronts us with the limits of empiricism in moral and religious philosophy. Hume's last work, if read philosophically, exhibits the vacancy of empiricism.

On some occasions of self-reference there can be two equally viable forms available to speakers: individual self-reference and collective self-reference. This means that selection of one or the other in talk-in-interaction can — akin to the selection of terms for reference to non-present persons — be guided by such considerations as recipient design and action formation. As a strategy for investigating the selection of self-reference terms, this article examines repairs to self-reference that change the form of reference (...) from individual to collective and vice versa. We first identify two repair operations found in the domain of self-reference: aggregation and extraction and then we track the use of both operations across a range of positions in the repair initiation opportunity space. Finally we consider some of the interactional uses of aggregation and extraction repairs in resolving sources of troubles associated with speaker epistemic authority and responsibility for described actions.

In an effort to assess the latest thinking in the Roman Catholic Church on economic matters, we examine the newest encyclical by Pope Benedict XVI, Caritas in Veritate (Charity in Truth) for guidance concerning marketing and business strategy. Core ethical values, consistent with historical Catholic Social Teachings (CST), are retained. However, some important nuances are added to previous treatments, and, reflecting the mind of the current Pontiff, certain points of emphasis are shifted to account for recent global developments. Key areas (...) of consistency and differences (as we perceive them) are spelled out along with some brief commentary on the evolution of the CST position on matters of importance to business decision makers. We close our analysis with a brief discussion of how the lessons of the encyclical can be applied to selected marketing problems embedded with ethical issues, including some criteria for evaluating marketing programs. Finally, we note some editorial commentary published in the wake of the letter’s release along with our own summation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Mimesis: Culture, Art, SocietyGene FendtMimesis: Culture, Art, Society, by Gunter Gebauer and Christoph Wulf; translated by Don Reneau; 400 pp. Berkeley: University of California Press, 1995, $45.00 cloth, $18.00 paper.The purpose of this book is to develop “a historical reconstruction of important phases in the development of mimesis” (p. 1) from a brief discussion of its pre-Platonic Greek significance through contemporary thinkers. It is, then, not strictly a (...) philosophical text, as are most of the texts and authors the book takes up. It is, however, a significant effort in the history of ideas, and as such it is shot through with traces of the traditional tropes, shaping power, ideology, and even social relations of that discipline, particularly as it is practiced in the venerable school of German scholarship. That is, the structure, tone, and argument of the book are shaped mimetically. This book’s problematic is, then, not simply historical, as Republic’s problem with the poets is not simply philosophical. Rather, both books partake of mimesis, even while each one aims to criticize or set forth the concept’s historical development.Let this stand as notice of a deep philosophical problem with the method of historical criticism. In fairness we should note that the authors are not unconscious of their difficulty here: “The fact that mimesis cannot be represented without the use of mimetic processes poses the fundamental problem of theory formation in reference to our object. What is the relation between the representational and the represented world? Is the representation of representation structurally equivalent to simple representation?” (p. 21). The authors hope to moot the power of those questions, if not the questions themselves, by attending “first of all to representations of mimesis found in texts best selected for that purpose and only afterward begin to offer considerations of a more generalizing nature” (p. 21). Their reasoning and choice of texts here is the traditional trope of the discipline: a mimema. Among other things, this methodos requires that the authors treat Girard as developing a “literary critical examination of [mimesis in] nineteenth and twentieth century novels” (p. 359n1) and a “new ordering of nineteenth century social relations” (p. 235), rather than, as he claims, a comprehensive anthropological thesis. At least, this method requires treating the former as essential, and the latter as less justifiable, for if Girard’s anthropological thesis about mimesis were justifiable a history of the idea of mimesis would be merely a heresiology. This problem can be restated mutatis mutandis for such thinkers as Plato and Augustine, whose theses—if they have theses—about mimesis are deeply anthropological.Two further questions arise early on and remain at the end. If, as the authors hold (and show), “the concept of mimesis necessarily loses its intellectual centrality with the rise of rational thought,” so much so that “the field of art, which comes to be regarded in the process as autonomous, undergoes a complete and fundamental restructuring” (p. 3), must we not begin to [End Page 199] suspect—as recent philosophers like Derrida attempt to show—that there is a dialectical relationship between the intentional, truth-functional relations of modern rational thought and the mimetic, unformalizable and “ambivalent” (pp. 2–3) processes of mimesis? Rather than conclude that “the question what is mimesis? is one which demonstratively leads to error” (p. 309), does it not begin to seem that intentional representation, as most visible in science, and mimetic assimilations, as most obviously effective in art, are together the necessary dialectical elements of culture, art and science? While it seems that the rise of rational scientific thought pushes mimesis to the social fringes of the arts, isn’t scientific activity and writing still just as much subject, and just as much a product, of the power of mimesis as art? Similarly art is just as bound as science to “probability” or “the convincing impossibility,” to recall Aristotle. This idea is not entirely foreign to the book; it appears subliminally as a plausible explication of the work of theorists like Benjamin and Adorno (pp. 267–93).The third difficulty is a question about selection. As in Auerbach’s renowned precursor, Wulf... (shrink)

I consider two attempts to combine realism with pluralism about the units of selection: Sober and Wilson’s combination of “model” and “unit” pluralism, and Sterelny and Griffiths’ “local pluralism”. I argue that both of these attempts fail to show that realism and pluralism are compatible. Sober and Wilson’s pluralism turns out, on closer inspection, to be a kind of monism in disguise, while Sterelny and Griffiths’ local pluralism involves a combination of realism and anti-realism about interactors, and the (...) units of selection, that is fundamentally unstable. My conclusion is that one must choose whether to be a realist or a pluralist in this area: one cannot be both. The question of which we should choose is a further question that I do not take a stand on. (shrink)

Charles Siewert has given us an ingenious thought experiment involving a limited lack of conscious experience. The possibility of the described case is incompatible with a number of popular theories of consciousness. Siewert acknowledges, however, that this possibility is not a direct threat to "hidden feature" theories. I aim to do two things: first, strengthen his defense of the claim that the case is genuinely possible by considering and rejecting some further attempts to explain away our temptation to believe it (...) possible; and second, to explore how a hidden feature approach could be developed and made plausible.

In lieu of an abstract, here is a brief excerpt of the content:Walking the Bodhisattva Path/Walking the Christ PathU.S. Conference of Catholic BishopsCatholics and Buddhists brought together by Dharma Realm Buddhist Association, the San Francisco Zen Center, and the United States Conference of Catholic Bishops (USCCB) met 20-23 March 2003 in the first of an anticipated series of four annual dialogues. Abbot Heng Lyu, the monks and nuns, and members of the Dharma Realm Buddhist Association hosted the dialogue at the (...) City of Ten Thousand Buddhas in Talmage, California. The community had transformed their Confucius Hall into a chapel, with a large, newly constructed wooden cross on a wall above an altar facing out from a raised platform, so the Catholic delegation would have a space for worship. A special poster announcing the theme of the conference, "Walking the Bodhisattva Path/Walking the Christ Path," showing a Buddhist dharma wheel at one foot of a bridge and a Celtic cross at the other foot, had been created by the hosting community.The daily schedule for the dialogue did not interfere with the monastic routine at the City of Ten Thousand Buddhas, which included early morning chanting (4:00-5:00 am), daily rituals in the Buddha Hall, and the single large meal for monastics before noon to which all participants were invited. Catholics and Buddhists meeting in the dialogue began each day with an optional forty-five minutes of quiet sitting together in the monastery meditation hall, each following their own form of meditation and prayer. There was a Eucharist on Friday and Saturday evenings for the Catholics and to which the Buddhists were invited, and additional meals of breakfast and supper throughout the meeting at the City's Jyun Kang Restaurant.Fourteen Buddhists and fourteen Catholics participated in the formal discussions. Each participant spoke on what it means to them to follow Christ or the way of the Bodhisattvas or enlightened beings. In addition to speaking, each participant distributed a short passage, usually from a traditional text, on this topic. Several passages from Master Dogen's Shobogenzo and the Gospel of John were among those shared by the group. Other passages shared were taken from the Avatamsaka Sutra and the Shurangama Sutra and from the other gospels and the writings of Zen master HakuinZenji, the Dalai Lama, Korean Zen Master I-sahn Hye-yeon, the teachings of Master [End Page 247] Hsuan Hua, Shantideva, Origen, St. Ignatius, St. Benedict, the author of The Cloud of Unknowing, St. John of the Cross, and Chiara Lubich. A minute of silence separated the fifteen-minute segments for each presentation. With so large a group, most of the time in the formal sessions involved listening to series of presentations; however, during discussion periods the participants asked several challenging questions of one another.Some participants noted the tension they felt between belonging to a particular religious group and the need to let go of any consequential narrowness. The goal of the discussion was to promote understanding of the differences and similarities between Christianity and Buddhism. At one point, the participants noted several concerns about mutual enrichment: whether Buddhist methods can be separated from Buddhism and Christian methods from Christianity, and what specific aspects of Christian practice truly enrich Buddhists and which Buddhist practices likewise enrich Christians. Several times participants discussed their understanding of terms such as transformation, grace, the incarnation and the passion of Jesus, discernment of spirits, prayer, Buddha-nature, and related terms. There was consensus that Buddhists and Catholics can practically help one another regarding mental cultivation and religious precepts. They expressed this consensus in their choice of the topic forthe next dialogue, "Transformation of Hearts and Minds: Chan/Zen-Catholic Approaches to Precepts."The group agreed to reconvene in 2004 to respond to six presentations, three from each side, on different aspects of this topic.Chairing the sessions were Rev. Heng Sure for the Dharma Realm Buddhist Association, Rev. Taigen Dan Leighton for the San Francisco Zen Center, and Bishop John Webster for the United States Conference of Catholic Bishops. Their three organizations are the sponsors of the Northern California Chan/Zen-Catholic Dialogue. Chan and Zen are respectively the Chinese and Japanese terms for the meditation school... (shrink)

Sober and Lewontin's critique of genic selectionism is based upon the principle that a unit of selection should make a context‐independent contribution to fitness. Critics have effectively shown that this principle is flawed. In this paper I show that the context independence principle is an instance of a more general principle for characterizing causes,called the contextual unanimity principle. I argue that this latter principle, while widely accepted, is erroneous. What is needed is to replace the approach to causality (...) characterized by the contextual unanimity criterion with an approach based on the concept of causal mechanism. After sketching such an approach, I show how it can be used to shed light on the units of selection problem. (shrink)

Brandon ([1982] 1984, 1990) has argued that Salmon's (1971) concept of screening-off can be used to characterize (i) the idea that natural selection acts directly on an organism's phenotype, only indirectly on its genotype, and (ii) the biological problem of the levels of selection. Brandon also suggests (iii) that screening-off events in a causal chain are better explanations than the events they screen off. This paper critically evaluates Brandon's proposals.

I argue that four of the fundamental claims of those calling themselves `genic pluralists'Philip Kitcher, Kim Sterelny, and Ken Watersare defective. First, they claim that once genic selectionism is recognized, the units of selection problems will be dissolved. Second, Sterelny and Kitcher claim that there are no targets of selection. Third, Sterelny, Kitcher, and Waters claim that they have a concept of genic causation that allows them to give independent genic causal accounts of all selection processes. I (...) argue that each one of these claims is either false or misleading. Moreover, the challenge that arises from the availability of genic causal accounts, namely, the inability to choose on rational grounds among genic and higher-level accounts, is unsupported.

This paper introduces the reconstitutor as a comprehensive unit of heredity within the context of evolutionary research. A reconstitutor is the structure resulting from a set of relationships between different elements or processes that are actively involved in the recreation of a specific phenotypic variant in each generation regardless of the biomolecular basis of the elements or whether they stand in a continuous line of ancestry. Firstly, we justify the necessity of introducing the reconstitutor by showing the limitations (...) of other evolutionary conceptions of the unit of heredity, such as the replicator, the reproducer, and the Darwinian individual. We argue that these conceptions are based on the requirement of lineage formation, which we argue to be unnecessary for the existence of evolutionary heredity. In the second part, we introduce the reconstitutor, which we base on the concept of Stability of Traits, and illustrate how it covers cases of hereditary phenomena not covered by the previous accounts. Secondly, we illustrate how the reconstitutor could serve as a platform to rethink ecological inheritance and other forms of inheritance that have been recently introduced under the song/singer model of evolution.

On the basis of distinctions between those properties of entities that can be defined without reference to other entities and those that (in different ways) cannot, this note argues that non-trivial forms of frequency-dependent selection of entities should be interpreted as selection occurring at a level higher than that of those entities. It points out that, except in degenerately simple cases, evolutionary game-theoretic models of selection are not models of individual selection. Similarly, models of genotypic (...) class='Hi'>selection such as heterosis cannot be legitimately interpreted as models of genic selection. The analysis presented here supports the views that: (i) selection should be viewed as a multi-level process; (ii) upper-level selection is ubiquitous; (iii) kin selection should be viewed as a type of group selection rather than individual selection; and (iv) inclusive fitness is not an individual property.

Genic selectionists (Williams 1966; Dawkins 1976) defend the view that genes are the (unique) units of selection and that all evolutionary events can be adequately represented at the genic level. Pluralistic genic selectionists (Sterelny and Kitcher 1988; Waters 1991; Dawkins 1982) defend the weaker view that in many cases there are multiple equally adequate accounts of evolutionary events, but that always among the set of equally adequate representations will be one at the genic level. We describe a range of (...) cases all involving stable equilibria actively maintained by selection. In these cases genotypic models correctly show that selection is active at the equilibrium point. In contrast, the genic models have selection disappearing at equilibrium. For deterministic models this difference makes no difference. However, once drift is added in, the two sets of models diverge in their predicted evolutionary trajectories. Thus, contrary to received wisdom on this matter, the two sets of models are not empirically equivalent. Moreover, the genic models get the facts wrong. (shrink)

This chapter offers a review of standard views about the requirements for natural selection to shape evolution and for the sorts of ‘units’ on which selection might operate. It then summarizes traditional arguments for genic selectionism, i.e., the view that selection operates primarily on genes (e.g., those of G. C. Williams, Richard Dawkins, and David Hull) and traditional counterarguments (e.g., those of William Wimsatt, Richard Lewontin, and Elliott Sober, and a diffuse group based on life history strategies). (...) It then offers a series of responses to the arguments, based on more contemporary considerations from molecular genetics, offered by Carmen Sapienza. A key issue raised by Sapienza concerns the degree to which a small number of genes might be able to control much of the variation relevant to selection operating on such selectively critical organs as hearts. The response to these arguments suggests that selection acts on many levels at once and that sporadic selection, acting with strong effects, can act successively on different key traits (and genes) while maintaining a balance among many potentially conflicting demands faced by organisms within an evolving lineage.

The aim of this paper is to offer a new biological interpretation of Fisher’s ‘Fundamental Theorem of Natural Selection’ and from this to consider optimality properties of gene frequency changes. These matters are of continuing interest to biologists and philosophers alike. In particular, the extent to which biological evolution can be calculated from the ‘gene’s-eye’ point of view is also discussed. In this sense, the paper bears indirectly on the concepts of the unit of selection and of (...) the ‘selfish gene’. A new biological significance for the Fundamental Theorem, not previously found in the literature, is offered, together with an optimality principle connected with this theorem. (shrink)

Holobionts, consisting of a host and diverse microbial symbionts, function as distinct biological entities anatomically, metabolically, immunologically, and developmentally. Symbionts can be transmitted from parent to offspring by a variety of vertical and horizontal methods. Holobionts can be considered levels of selection in evolution because they are well-defined interactors, replicators/reproducers, and manifestors of adaptation. An initial mathematical model is presented to help understand how holobionts evolve. The model offered combines the processes of horizontal symbiont transfer, within-host symbiont proliferation, vertical (...) symbiont transmission, and holobiont selection. The model offers equations for the population dynamics and evolution of holobionts whose hologenomes differ in gene copy number, not in allelic or loci identity. The model may readily be extended to include variation among holobionts in the gene identities of both symbionts and host. (shrink)

This paper defends global realism about the units of selection, the view that there is always (or nearly always) an objective fact of the matter concerning the level at which natural selection acts. The argument proceeds in two stages. First, it is argued that global conventionalist-pluralism is false. This is established by identifying plausible sufficient conditions for irreducible selection at a particular level, and showing that these conditions are sometimes satisfied in nature. Second, it is argued that (...) local pluralism – the view that while realism is true of some selection regimes, pluralist conventionalism holds for others – should also be rejected. I show that the main arguments for local pluralism are consistent with global realism. I also suggest that local pluralism offers an unacceptably disunified view of the metaphysics of selection. It follows that we should accept global realism. But this leaves open the question of how to classify so called ‘multi-level selection type 1’ (MLS1) processes, such as Wilson’s classic trait-group model for the evolution of altruism: should they be interpreted as particle selection or collective selection? On the assumption of global realism, at most one of these is correct. I argue, against global realists such as Sober, that MLS1 processes should be understood as particle, not collective, selection, due to three features of MLS1: the reducibility of collective fitness, the absence of collective reproduction, and the dispensable role of collectives.

A set of constraints forces trade-offs which prevent us from achieving the best possible definitions of the ‘level’ and ‘unit’ of natural selection. This set consists in decisions concerning conflicting pre-analytic intuitions in problematic cases, the relative roles of various conceptual resources in the definitions, which facts need to be accounted for using the definitions, how the relation between selection and evolution orients the definitions, and the relation between the level and unit concepts. Systematic reconstruction and (...) evaluation of leading analyses along these dimensions favors a new functional analysis over Williams’ consequentialist analysis, Sober’s causal analysis, and Dawkins’ teleological analysis.

In 2015, a flourish of “alarums and excursions” by the scientific community propelled CRISPR/Cas9 and other new gene-editing techniques into public attention. At issue were two kinds of potential gene-editing experiments in humans: those making inheritable germ-line modifications and those designed to enhance human traits beyond what is necessary for health and healing. The scientific consensus seemed to be that while research to develop safe and effective human gene editing should continue, society's moral uncertainties about these two kinds of experiments (...) needed to be better resolved before clinical trials of either type should be attempted. In the United States, the National Academies of Science, Engineering and Medicine convened the Committee on Human Gene Editing: Scientific, Medical and Ethical Considerations to pursue that resolution. The committee's 2017 consensus report has been widely interpreted as “opening the door” to inheritable human genetic modification and holding a line against enhancement interventions. But on a close reading it does neither. There are two reasons for this eccentric conclusion, both of which depend upon the strength of the committee's commitment to engaging diverse public voices in the gene-editing policy-making process.

In recent years philosophers have attempted to clarify the units of selection controversy in evolutionary biology by offering conceptual analyses of the term 'unit of selection'. A common feature of many of these analyses is an emphasis on the claim that units of selection are entities exhibiting heritable variation in fitness. In this paper I argue that the demand that units of selection be characterized in terms of heritability is unnecessary, as well as undesirable, on (...) historical, theoretical, and philosophical grounds. I propose a positive account of the proper referent of the term 'unit of selection', distinguishing between the processes of evolution and phenotypic selection. The main result of this analysis is greater clarity about the conceptual structure of evolutionary theory. (shrink)

In both biology and the human sciences, social groups are sometimes treated as adaptive units whose organization cannot be reduced to individual interactions. This group-level view is opposed by a more individualistic one that treats social organization as a byproduct of self-interest. According to biologists, group-level adaptations can evolve only by a process of natural selection at the group level. Most biologists rejected group selection as an important evolutionary force during the 1960s and 1970s but a positive literature (...) began to grow during the 1970s and is rapidly expanding today. We review this recent literature and its implications for human evolutionary biology. We show that the rejection of group selection was based on a misplaced emphasis on genes as “replicators” which is in fact irrelevant to the question of whether groups can be like individuals in their functional organization. The fundamental question is whether social groups and other higher-level entities can be “vehicles” of selection. When this elementary fact is recognized, group selection emerges as an important force in nature and what seem to be competing theories, such as kin selection and reciprocity, reappear as special cases of group selection. The result is a unified theory of natural selection that operates on a nested hierarchy of units.The vehicle-based theory makes it clear that group selection is an important force to consider in human evolution. Humans can facultatively span the full range from self-interested individuals to “organs” of group-level “organisms.” Human behavior not only reflects the balance between levels of selection but it can also alter the balance through the construction of social structures that have the effect of reducing fitness differences within groups, concentrating natural selection (and functional organization) at the group level. These social structures and the cognitive abilities that produce them allow group selection to be important even among large groups of unrelated individuals. (shrink)

Much recent work in sociobiology can be understood as designed to demonstrate the sufficiency of selection operating at lower levels of organization by the development of models at the level of the gene or the individual. Higher level units are accordingly viewed as artifacts of selection operating at lower levels. The adequacy of this latter form of argument is dependent upon issues of the complexity of the systems under consideration. A taxonomy is proposed elaborating a series of types, (...) or grades, of hierarchically organized systems. These range from aggregative systems, in which there is no organization relevant to systemic properties, through several graded variations reflecting various degrees of functional interdependence of components, to integrated systems, which manifest component specialization and diversification as well as a subordination of component function to systemic function. It is suggested that the most complex form of organization is plausibly treated as indicative of higher level units of selection. (shrink)

The role of imagery in encoding event-based prospective memories has yet to be fully clarified. Herein, it is argued that imagery augments a cue-to-context association that supports event-based prospective memory performance. By this account, imagery encoding not only improves prospective memory performance but also reduces interference to intention-related information that occurs outside of context. In the current study, when lure words occurred outside of the appropriate responding context, the use of imagery encoding strategies resulted in less interference when compared with (...) a standard event-based intention condition. This difference was eliminated when participants were not given a specific context to associate their intention . These results support a cue-to-context association account of how imagery operates in certain event-based prospective memory tasks. (shrink)

Peter Winch famously critiqued Michael Oakeshott's view of human conduct. He argued that Oakeshott had missed the fact that truly human conduct is conduct that 'follows a rule.' This paper argues that, as is sometimes the case with Oakeshott, what seems, on the surface, to be a disagreement with another, somewhat compatible thinker about a matter of detail in some social theory in fact turns out to point to a deeper philosophical divide. In particular, I contend, Winch, as typical of (...) those who only picked up on Oakeshott's work in the 1940s and 1950s, when Oakeshott became known for his critique of rationalism, failed to understand the idealist metaphysics underlying that critique.
