Two controversies exist regarding the appropriate characterization of hierarchical and adaptive evolution in natural populations. In biology, there is the Wright-Fisher controversy over the relative roles of random genetic drift, natural selection, population structure, and interdemic selection in adaptive evolution begun by Sewall Wright and Ronald Aylmer Fisher. There is also the Units of Selection debate, spanning both the biological and the philosophical literature and including the impassioned group-selection debate. Why do these two discourses exist (...) separately, and interact relatively little? We postulate that the reason for this schism can be found in the differing focus of each controversy, a deep difference itself determined by distinct general styles of scientific research guiding each discourse. That is, the Wright-Fisher debate focuses on adaptive process, and tends to be instructed by the mathematical modeling style, while the focus of the Units of Selection controversy is adaptive product, and is typically guided by the function style. The differences between the two discourses can be usefully tracked by examining their interpretations of two contested strategies for theorizing hierarchical selection: horizontal and vertical averaging.

For principled and substantially philosophical reasons, based largely on his reform of natural history by inverting the Paleyan notion of overarching and purposeful beneficence in the construction of organisms, Darwin built his theory of selection at the single causal level of individual bodies engaged in unconscious struggle for their own reproductive success. But the central logic of the theory allows selection to work effectively on entities at several levels of a genealogical hierarchy, provided that they embody a set (...) of requisite features for defining evolutionary individuality. Genes, cell lineages, demes, species, and clades-as well as Darwin’s favoured organisms-embody these requisite features in enough cases to form important levels of selection in the history of life. R. A. Fisher explicitly recognized the unassailable logic of species selection, but denied that thsi real process could be important in evolution because, compared with the production of new organisms within a species, the origin of new species is so rare, and the number of species within most clades so low. I review this and other classical arguments against higher-level selection, and conclude that they are invalid in practice for interdemic selection, and false in principle for species selection. Punctuated equilibrium defines the individuality of species and refutes Fisher’s classical argument based on cycle time. In the second part of the paper, I argue that we have failed to appreciate the range and power of selection at levels above and below the organismic because we falsely extrapolate the defining properties of organisms to these other levels, and then regard the other levels as impotent because their effective individuals differ so much from organisms. We would better appreciate the power and generality of hierarchical models of selection if we grasped two key principles: first, that levels can interact in all modes, and not only in the negative style that, for heuristic and operational reasons, has received almost exclusive attention in the existing literature; and second, that each hierarchical level differs from all others in substantial and interesting ways, both in the style and frequency of patterns in change and causal modes.

In a previous study, using experimental metapopulations of the flour beetle, Tribolium castaneum, we investigated phase III of Wright's shifting balance process (Wade and Griesemer 1998). We experimentally modeled migration of varying amounts from demes of high mean fitness into demes of lower mean fitness (as in Wright's characterization of phase III) as well as the reciprocal (the opposite of phase III). We estimated the meta-populational heritability for this level of selection by regression of offspring deme means on the (...) weighted parental deme means.Here we develop a Punnett Square representation of the inheritance of the group mean to place our empirical findings in a conceptual context similar to Mendelian inheritance of individual traits. The comparison of Punnett Squares for individual and group inheritance shows how the latter concept can be rigorously defined and extended despite the lack of explicitly formulated, simple Mendelian laws of inheritance at the group level. Whereas Wright's phase III combines both interdemic selection and meta-populational inheritance, our formulation separates the issue of meta-populational heritability from that of interdemic selection. We use this conceptual context to discuss the controversies over the levels of selection and the units of inheritance. (shrink)

Plant and animal species are information-processing entities of such complexity, integration, and adaptive competence that it may be scientifically fruitful to consider them intelligent. The possibility arises from the analogy between learning and evolution, and from recent developments in evolutionary science, psychology and cognitive science. Species are now described as spatiotemporally localized individuals in an expanded hierarchy of biological entities. Intentional and cognitive abilities are now ascribed to animal, human, and artificial intelligence systems that process information adaptively, and that manifest (...) problem-solving abilities. The structural and functional similarities between such systems and species are extensive, although they “are usually obscured by population-genetic metaphors that have nonetheless contributed much to our understanding of evolution.In this target article, I use Sewall Wright's notion of the “adaptive landscape” to compare the performances of evolving species to those of intelligent organisms. With regard to their adaptive achievements and the kinds of processes by which they are achieved, biological species compare very favorably to intelligent animals by virtue of interactions between populations and their environments, between ontogeny and phylogeny, and between natural, interdemic, organic, and species selection. Addressing the question of whether species are intelligent could help to refine our ideas about species, evolution, and intelligence, and could open new lines of empirical and theoretical inquiry in many disciplines.

In Emotions, Values & Agency, Christine Tappolet develops a sophisticated, perceptual theory of emotions and their role in wide range of issues in value theory and epistemology. In this paper, we raise three worries about Tappolet's proposal.

This chapter provides a critical overview and interpretation of fair subject selection in clinical and social scientific research. It first provides an analytical framework for thinking about the problem of fair subject selection. It then argues that fair subject selection is best understood as a set of four subprinciples, each with normative force and each with distinct and often conflicting implications for the selection of participants: fair inclusion, fair burden sharing, fair opportunity, and fair distribution of (...) third-party risks. It then defends an approach to navigating the conflicting imperatives of these subprinciples, one which privileges the need to include epistemically distinct groups in research, before concluding by considering the most pressing research questions regarding fair subject selection.

Selective abduction is in contrast with creative abduction as well as Inference to the Best Explanation (IBE). There are two types of selective abduction: Either hypotheses are selected among new and conjectural hypotheses without any prior knowledge ( Pierce s' selective abduction), or the selection of the best hypotheses and explanations is among a large number of possible hypotheses and explanations already known (L. Magnani's selective abduction and G. Schurz's factual abduction). According to both views, as well as an (...) alternative view, which belongs to Dov M. Gabby and John Woods, selective abduction is different from inference to the best explanation. Schurz's factual abduction depends on all three sub-processes of inference, i.e.: colligation, observation, and judgment (c, o, and j); But Pierce's selective abduction, on the other hand, has only a third sub-process, i.e. judgment process (j), and therefore it cannot be regarded as a process of abductive epistemic inference.

Selective permeability holds that people’s distinct capacities allow them to do different things in a space, making it unequally accessible. Though mainly applied to urban geography so far, we propose selective permeability as an affordance-based approach for understanding diversity in education. This has advantages. First, it avoids dismissing lower achievements as necessarily coming from “within” students, instead locating challenges in the environment. This implies that settings (not just people) need remedial attention, also raising questions about normative judgments in disability nomenclature. (...) Second, affordances can be negotiated in numerous ways to reach a goal, analogously to how people with missing arms have learned to drive with their feet, so restrictive problem-solving methods are often counterproductive. Third, our approach illuminates how cultural factors ranging from gait styles to language and hence group coordination modulate action possibilities, so that cultural groups may encounter objectively different affordances in the same classroom. But fourth, while fit with environment allows for skill refinement, non-fit can contribute to growth situations, which suggests a degree of selective closure can be desirable. Throughout, we argue social constructs—including educational ones—are literally built or enacted barriers or openings that have reality in environments in the same way that affordances do. (shrink)

'To be taught to write or to speak - but what is the use of speaking, if you have nothing to say? To be taught to think - nay, what is the use of being able to think, if you have nothing to think of? But to be taught to see is to gain word and thought at once, and both true.' Ruskin was the most powerful and influential critic of the nineteenth century. He wrote about nature, art, architecture, politics, (...) history, myth, and much besides; all his work is characterized by a clarity of vision as unsettling and intense now as it was for his first readers. This new selection draws on the whole range of his astonishingly varied output, from the passionate celebration of J. M. W. Turner's painting in the first volume of Modern Painters to Praeterita, the elegiac autobiography of his later years. The introduction outlines Ruskin's life and thought, and shows why he remains such a rewarding writer today.

We have argued elsewhere that: (A) Natural selection is not a cause of evolution. (B) A resolution-of-forces (or vector addition) model does not provide us with a proper understanding of how natural selection combines with other evolutionary influences. These propositions have come in for criticism recently, and here we clarify and defend them. We do so within the broad framework of our own “hierarchical realization model” of how evolutionary influences combine.

Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection (...) that underlies it, we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

A common misunderstanding of the selected effects theory of function is that natural selection operating over an evolutionary time scale is the only functionbestowing process in the natural world. This construal of the selected effects theory conflicts with the existence and ubiquity of neurobiological functions that are evolutionary novel, such as structures underlying reading ability. This conflict has suggested to some that, while the selected effects theory may be relevant to some areas of evolutionary biology, its relevance to neuroscience (...) is marginal. This line of reasoning, however, neglects the fact that synapses, entire neurons, and potentially groups of neurons can undergo a type of selection analogous to natural selection operating over an evolutionary time scale. In the following, I argue that neural selection should be construed, by the selected effect theorist, as a distinct type of function-bestowing process in addition to natural selection. After explicating a generalized selected effects theory of function and distinguishing it from similar attempts to extend the selected effects theory, I do four things. First, I show how it allows one to identify neural selection as a distinct function-bestowing process, in contrast to other forms of neural structure formation such as neural construction. Second, I defend the view from one major criticism, and in so doing I clarify the content of the view. Third, I examine drug addiction to show the potential relevance of neural selection to neuroscientific and psychological research. Finally, I endorse a modest pluralism of function concepts within biology. (shrink)

The aim of this paper is to focus on the phenomenon of selective attention as pointing out important psychological cases where it is arguable that we can have practical reasons without the capacity to carry out any relevant inference. Selective attention also would serve to show the possibility to have very basic demonstrative references to particular perceptual items without the possession of any concept. I will argue that if we assume 1) that believing can be taken as a kind of (...) action and 2) that demonstrative references to particular empirical items in that so basic sense have an important epistemological role in all of our knowledge, then our conclusions would have a very large application. There would be reasons without inferences not only for acting but also for believing, anddemonstrative reference without concepts would be an uneliminable component of our knowledge. (shrink)

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly (...) phenomenon whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

Hegel's _Phenomenology of Spirit_, his first major work, is one of the classics of Western philosophy. Although previous translations, in whole or in part, have made the text available in English, they are for various reasons not fully adequate, especially for use in teaching undergraduates. Howard Kainz has therefore undertaken to provide his own translation of major selections from the work, which are tied together by summaries of the parts not translated so as to provide the reader with a sense (...) of the whole. The translated selections include the Introduction, Chapter I on Sensory-Certainty, the sections from Chapter IV on Self-Consciousness, the Master-Slave dialectic, and the Unhappy Consciousness, the introductory section to Chapter V on Reason, the sections in Chapter VI on Ethical Action, Absolute Liberty, and Shiftiness and the central argument of Chapter VIII on Absolute Knowledge. The translation is based on the 1980 "Akademie" edition of the _Phänomenologie des Geistes_, edited by Wolfgang Bonsiepen and Reinhard Heede, and the German original is printed alongside the English translation in parallel columns. This edition includes some of the editorial devices used by De Negri in his Italian translation and Hippolyte in his French translation—namely, the use of editorial subdivisions and subtitles to indicate major transitions in the text, plus commentary and cross-references by way of footnotes.

The notion that natural selection is a process of fitness maximization gets a bad press in population genetics, yet in other areas of biology the view that organisms behave as if attempting to maximize their fitness remains widespread. Here I critically appraise the prospects for reconciliation. I first distinguish four varieties of fitness maximization. I then examine two recent developments that may appear to vindicate at least one of these varieties. The first is the ‘new’ interpretation of Fisher's fundamental (...) theorem of natural selection, on which the theorem is exactly true for any evolving population that satisfies some minimal assumptions. The second is the Formal Darwinism project, which forges links between gene frequency change and optimal strategy choice. In both cases, I argue that the results fail to establish a biologically significant maximization principle. I conclude that it may be a mistake to look for universal maximization principles justified by theory alone. A more promising approach may be to find maximization principles that apply conditionally and to show that the conditions were satisfied in the evolution of particular traits. (shrink)

Procedures for the selection of subjects for participation in randomized clinical trials--usually formalized as eligibility criteria in the study protocol--have both scientific and ethical implications. In this thesis, I undertake an examination of eligibility criteria at three stages in the genesis and dissemination of medical knowledge: clinical trial protocol, interpretation by investigators, and reporting of study results.In the first chapter, ethical issues in subject selection are reviewed and the main study questions are presented. In the second chapter, the (...) results of an examination of eligibility criteria in two sets of clinical trials, one sponsored by the NSABP, the other sponsored by POG, covering a twenty-year time span are presented. The POG trials had far fewer eligibility criteria than the NSABP studies, suggesting that large numbers of criteria may not be necessary for high quality research. In the third chapter, the impact of subjective eligibility criteria on enrollment and investigator uncertainty is explored. Subjective criteria were associated with more variable enrollment decisions and greater uncertainty. Such criteria represent a threat to the validity, conduct and interpretation of trials and, therefore, should only be included when carefully justified. The fourth chapter examines the accuracy of the reporting of eligibility criteria in sets of corresponding study protocol, methods paper, journal article, and Clinical Alert. Important information is lost at each step in the dissemination of study results. Unnecessary criteria ought to be dropped at a trial's inception; all other criteria must be reported faithfully. The fifth chapter attempts to provide a comprehensive philosophical account of just selection procedures for clinical research using the political philosophy of Michael Walzer. The sixth, and last, chapter, discusses explanatory and pragmatic approaches to clinical trial design, overlapping scientific and ethical concerns related to eligibility criteria, and questions for further study.

The most comprehensive collection available in paperback of Bacon’s philosophical and scientific writings, this volume offers Bacon's major works in their entirety, or in substantive selections, revised from the classic 19th century editions of Spedding, Ellis, and Heath. Selections from some of Bacon's natural histories round out this edition by showing the types of compilations that he believed would most contribute to the third part of his Great Instauration. Each work has a separate brief introduction indicating the major themes developed. (...) In her general Introduction, Sargent gives a biographical sketch of Bacon's early life, education, and legal career, discusses the major components of his philosophical project, and traces his influence on subsequent natural philosophy. In addition, she looks at the primarily negative evaluations of Bacon's methodological writings by philosophers of science in the first half of the twentieth century, the reassessments of his works that took place as the influence of logical empiricism declined, and the current revival of interest in Bacon that coincides with the focus on experimental practice today.

Various results show the ‘formal equivalence’ of kin and group selectionist methodologies, but this does not preclude there being a real and useful distinction between kin and group selection processes. I distinguish individual- and population-centred approaches to drawing such a distinction, and I proceed to develop the latter. On the account I advance, the differences between kin and group selection are differences of degree in the structural properties of populations. A spatial metaphor provides a useful framework for thinking (...) about these differences: kin and group selection may be conceptualized as large, overlapping regions of K - G space. I then consider some implications of the account, defend it from possible objections, and further argue that the structural features characteristic of both kin and group selection may recur at multiple levels of biological organization.

In their book What Darwin Got Wrong, Jerry Fodor and Massimo Piattelli-Palmarini construct an a priori philosophical argument and an empirical biological argument.

A recent development in biology has been the growing acceptance that holobionts, entities comprised of symbiotic microbes and their host organisms, are widespread in nature. There is agreement that holobionts are evolved outcomes, but disagreement on how to characterize the operation of natural selection on them. The aim of this paper is to articulate the contours of the disagreement. I explain how two distinct foundational accounts of the process of natural selection give rise to competing views about evolutionary (...) individuality. (shrink)

Human behavior is the joint product of (i) contingencies of survival responsible for natural selection, and (ii) contingencies of reinforcement responsible for the repertoires of individuals, including (iii) the special contingencies maintained by an evolved social environment. Selection by consequences is a causal mode found only in living things, or in machines made by living things. It was first recognized in natural selection: Reproduction, a first consequence, led to the evolution of cells, organs, and organisms reproducing themselves (...) under increasingly diverse conditions. The behavior functioned well, however, only under conditions similar to those under which it was selected.Reproduction under a wider range of consequences became possible with the evolution of processes through which organisms acquired behavior appropriate to novel environments. One of these, operant conditioning, is a second kind of selection by consequences: New responses could be strengthened by events which followed them. When the selecting consequences are the same, operant conditioning and natural selection work together redundantly. But because a species which quickly acquires behavior appropriate to an environment has less need for an innate repertoire, operant conditioning could replace as well as supplement the natural selection of behavior.Social behavior is within easy range of natural selection, because other members are one of the most stable features of the environment of a species. The human species presumably became more social when its vocal musculature came under operant control. Verbal behavior greatly increased the importance of a third kind of selection by consequences, the evolution of social environments or cultures. The effect on the group, and not the reinforcing consequences for individual members, is responsible for the evolution of culture. (shrink)

Despite the voluminous literature on biological functions produced over the last 40 years, few philosophers have studied the concept of function as it is used in neuroscience. Recently, Craver (forthcoming; also see Craver 2001) defended the causal role theory against the selected effects theory as the most appropriate theory of function for neuroscience. The following argues that though neuroscientists do study causal role functions, the scope of that theory is not as universal as claimed. Despite the strong prima facie superiority (...) of the causal role theory, the selected effects theory (when properly developed) can handle many cases from neuroscience with equal facility. It argues this by presenting a new theory of function that generalizes the notion of a ‘selection process’ to include processes such as neural selection, antibody selection, and some forms of learning—that is, to include structures that have been differentially retained as well as those that have been differentially reproduced. This view, called the generalized selected effects theory of function, will be defended from criticism and distinguished from similar views in the literature. (shrink)

Here I advance two related evolutionary propositions. (1) Natural selection is most often considered to require competition between reproducing “individuals”, sometimes quite broadly conceived, as in cases of clonal, species or multispecies-community selection. But differential survival of non-competing and non-reproducing individuals will also result in increasing frequencies of survival-promoting “adaptations” among survivors, and thus is also a kind of natural selection. (2) Darwinists have challenged the view that the Earth’s biosphere is an evolved global homeostatic system. Since (...) there is only one biosphere, reproductive competition cannot have been involved in selection for such survival-promoting adaptations, they claim. But natural selection through survival could reconcile Gaia with evolutionary theory. (shrink)

This paper has a triple aim. First of all, it makes a comparison between Foucault’s notion of power relations and the notion of natural selection as it has been developed, since Darwin, by evolutionary biology. A number of common points between these two notions are analyzed here, such as acting on a spontaneity, facticity, fundamental visibility and global character. By analyzing these common points, this paper attempts – and this is its second aim – to indicate and criticize several (...) preconceptions about natural selection that still plague the comprehension, especially of non-specialists, of the notion of natural selection. Finally, by a thorough analysis of these common features, this article also attempts to indicate a point of radical divergence between these two notions, i.e. a central point that makes it impossible for the two notions to find a common application ground.

Sexual selection processes have received much attention in recent years, attention reflected in interest in human mate preferences. Among these mate preferences are preferences for physical attractiveness. Preferences in and of themselves, however, do not fully explain the nature of the relationships that individuals attain. A tacit negotiation process underlies relationship formation and maintenance. The notion that preferences for physical attractiveness evolved under parasite-driven “good genes” sexual selection leads to predictions about the nature of trade-offs that individuals make (...) between mates’ physical attractiveness and investment potential. These predictions and relevant data are explored, with a primary emphasis on women’s preferences for men’s qualities. In addition, further implications of trade-offs are examined, most notably (a) the impact of environmental variations on the nature of mating and (b) some effects of trade-offs on infidelity and male attempts to control women.

Hamilton’s theory of kin selection is the best-known framework for understanding the evolution of social behavior but has long been a source of controversy in evolutionary biology. A recent critique of the theory by Nowak, Tarnita, and Wilson sparked a new round of debate, which shows no signs of abating. In this overview, we highlight a number of conceptual issues that lie at the heart of the current debate. We begin by emphasizing that there are various alternative formulations of (...) Hamilton’s rule, including a general version, which is always true; an proximate version, which assumes weak selection; and a special version, which demands other restrictive assumptions. We then examine the relationship between the neighbor-modulated fitness and inclusive fitness approaches to kin selection. Finally, we consider the often-strained relationship between the theories of kin and multilevel selection. (shrink)

In this paper, using a multilevel approach, we defend the positive role of natural selection in the generation of organismal form. Despite the currently widespread opinion that natural selection only plays a negative role in the evolution of form, we argue, in contrast, that the Darwinian factor is a crucial (but not exclusive) factor in morphological organization. Analyzing some classic arguments, we propose incorporating the notion of ‘downward causation’ into the concept of ‘natural selection.’ In our opinion, (...) this kind of causation is fundamental to the operation of selection as a creative evolutionary process.

The scientific realism debate has now reached an entirely new level of sophistication. Faced with increasingly focused challenges, epistemic scientific realists have appropriately revised their basic meta-hypothesis that successful scientific theories are approximately true: they have emphasized criteria that render realism far more selective and, so, plausible. As a framework for discussion, I use what I take to be the most influential current variant of selective epistemic realism, deployment realism. Toward the identification of new case studies that challenge this form (...) of realism, I break away from the standard list and look to the history of celestial mechanics, with an emphasis on twentieth century advances. I then articulate two purely deductive arguments that, I argue, properly capture the historical threat to realism. I contend that both the content and form of these novel challenges seriously threaten selective epistemic realism. I conclude on a positive note, however, arguing for selective realism at a higher level. Even in the face of threats to its epistemic tenet, scientific realism need not be rejected outright: concern with belief can be bracketed while nonetheless advocating core realist tenets. I show that, in contrast with epistemic deployment realism, a purely axiological scientific realism can account for key scientific practices made salient in my twentieth century case studies. And embracing the realists favored account of inference, inference to the best explanation, while pointing to a set of the most promising alternative selective realist meta-hypothesis, I show how testing the latter can be immensely valuable to our understanding of science.

The book presents a new way of understanding Darwinism and evolution by natural selection, combining work in biology, philosophy, and other fields.

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.

Natural selection [Darwin 1859] is perhaps the most important component of evolutionary theory, since it is the only known process that can bring about the adaptation of living organisms to their environments [Gould 2002]. And yet, its study is conceptually and methodologically complex, and much attention needs to be paid to a variety of phenomena that can limit the efficacy of selection [Antonovics 1976; Pigliucci and Kaplan 2000]. In this essay, I will use examples of recent work carried (...) out in my laboratory to illustrate basic research on natural selection as conducted using a variety of approaches, including field work, laboratory experiments, and molecular genetics. I also discuss the application of this array of tools to questions pertinent to conservation biology, and in particular to the all-important problem of what makes invasive species so good at creating the sort of problems they are infamous for [Lee 2002].

this requirement for adaptations. Emergent characters are always potential adaptations. Not all selection processes produce adaptations, however. The key issue, in delineating a selection process, is the relationship between a character and fitness. The emergent character approach is more restrictive than alternative schemas that delineate selection..

Selection type theories solve adaptation problems. Natural selection, clonal selection for antibody production, and selective theories of higher brain function are examples. An abstract characterization of typical selection processes is generated by analyzing and extending previous work on the nature of natural selection.

This suggests the potential fruitfulness (...) of research to find other theory types and construct their abstractions. (shrink)

Anti-selection occurs when information asymmetry exists between insurers and applicants. When an applicant knows they are at high risk of loss, but the insurer does not, the applicant may try to use this knowledge differential to secure insurance at a lower premium that does not match risk.

Individual realism asserts that our best scientific theories are (approximately) true. In contrast, selective realism asserts that only the stable posits of our best scientific theories are true.

The more scientists believe what their theories say about the world, the more they are motivated to exercise their imaginations and think up new theories and experiments. Therefore, individual realism better (...) fosters scientific creativity than selective realism. (shrink)

This PhD dissertation examines the conceptual and theoretical foundations of the most general and most widely used framework for understanding social evolution, W. D. Hamilton's theory of kin selection. While the core idea is intuitive enough (when organisms share genes, they sometimes have an evolutionary incentive to help one another), its apparent simplicity masks a host of conceptual subtleties, and the theory has proved a perennial source of controversy in evolutionary biology. To move towards a resolution of these controversies, (...) we need a careful and rigorous analysis of the philosophical foundations of the theory. My aim in this work is to provide such an analysis. I begin with an examination of the concepts behavioural ecologists employ to describe and classify types of social behaviour. I stress the need to distinguish concepts that are often conflated: for example, we need to distinguish simple cooperation from collaboration in collective tasks, behaviours from strategies, and control from manipulation and coercion. I proceed from here to the formal representation of kin selection via George R. Price’s covariance selection mathematics. I address a number of interpretative issues the Price formalism raises, including the vexed question of whether kin selection theory is ‘formally equivalent’ to multi-level selection theory. In the second half of the dissertation, I assess the uses and limits of Hamilton’s rule for the evolution of social behaviour; I provide a precise statement of the conditions under which the rival neighbour-modulated fitness and inclusive fitness approaches in contemporary kin selection theory are equivalent (and describe cases in which they are not); and I criticize recent formal attempts to establish the controversial claim that kin selection leads to organisms behaving as if maximizing their inclusive fitness.

In a recent comment on the HFEA’s public consultation on sex selection, Soren Holm claimed that proponents of family balancing are committed to embrace a laissez faire approach. Given that arguments in support of sex selection for family balancing also support sex selection for other social reasons, advocates of family balancing, he asserts, are simply inconsistent when calling for a limit on access to sex selection. In this paper, I argue that proponents of family balancing are (...) in no way inconsistent. Provided their advocacy of family balancing is aimed at preventing a severe distortion of the natural sex ratio, they are entirely justified in insisting on restrictions to sex selection. The real question is whether a concern for the sex ratio does indeed call for a limit on sex selection. Based on a recent survey on gender preferences and data from several Gender Clinics, I argue that a restriction on sex selection to family balancing is unwarranted. In the absence of any evidence for a pending sex ratio distortion, we are actually required to adopt a laissez faire approach to sex selection. (shrink)
