I analyze the importance of parts in the style of biological theorizing that I call compositional biology. I do this by investigating various aspects, including partitioning frames and explanatory accounts, of the theoretical perspectives that fall under and are guided by compositional biology. I ground this general examination in a comparative analysis of three different disciplines with their associated compositional theoretical perspectives: comparative morphology, functional morphology, and developmental biology. I glean data for this analysis from canonical textbooks and defend the (...) use of such texts for the philosophy of science. I end with a discussion of the importance of recognizing formal and compositional biology as two genuinely different ways of doing biology – the differences arising more from their distinct methodologies than from scientific discipline included or natural domain studied. Ultimately, developing a translation manual between the two styles would be desirable as they currently are, at times, in conflict. (shrink)

Levins and Lewontin have contributed significantly to our philosophical understanding of the structures, processes, and purposes of biological mathematical theorizing and modeling. Here I explore their separate and joint pleas to avoid making abstract and ideal scientific models ontologically independent by confusing or conflating our scientific models and the world. I differentiate two views of theorizing and modeling, orthodox and dialectical, in order to examine Levins and Lewontin’s, among others, advocacy of the latter view. I compare the positions of these (...) two views with respect to four points regarding ontological assumptions: (1) the origin of ontological assumptions, (2) the relation of such assumptions to the formal models of the same theory, (3) their use in integrating and negotiating different formal models of distinct theories, and (4) their employment in explanatory activity. Dialectical is here used in both its Hegelian–Marxist sense of opposition and tension between alternative positions and in its Platonic sense of dialogue between advocates of distinct theories. I investigate three case studies, from Levins and Lewontin as well as from a recent paper of mine, that show the relevance and power of the dialectical understanding of theorizing and modeling.

Reification is to abstraction as disease is to health. Whereas abstraction is singling out, symbolizing, and systematizing, reification is neglecting abstractive context, especially functional, historical, and analytical-level context. William James and John Dewey provide similar and nuanced arguments regarding the perils and promises of abstraction. They share an abstraction-reification account. The stages of abstraction and the concepts of “vicious abstractionism,” “/the/ psychologist’s fallacy,” and “the philosophic fallacy” in the works of these pragmatists are here analyzed in detail. For instance, in (...) 1896 Dewey exposes various fallacies associated with reifying dualistic reflex arc theory. The conclusion prescribes treatments (pluralism and assumption archaeology) for de-reifying ill models (i.e., universalized, narrowed, and ontologized models) in contemporary scientific fields such as cognitive science and biology.

Analytical categories of scientific cultures have typically been used both exclusively and universally. For instance, when styles of scientific research are employed in attempts to understand and narrate science, styles alone are usually employed. This article is a thought experiment in interweaving categories. What would happen if rather than employ a single category, we instead investigated several categories simultaneously? What would we learn about the practices and theories, the agents and materials, and the political-technological impact of science if we analyzed (...) and applied styles, paradigms, and models simultaneously? I address these questions in general and for a specific case study: a brief history of systematics. (shrink)

In this book, Kristina Musholt offers a novel theory of self-consciousness, understood as the ability to think about oneself. Traditionally, self-consciousness has been central to many philosophical theories. More recently, it has become the focus of empirical investigation in psychology and neuroscience. Musholt draws both on philosophical considerations and on insights from the empirical sciences to offer a new account of self-consciousness—the ability to think about ourselves that is at the core of what makes us human. -/- Examining theories (...) of nonconceptual content developed in recent work in the philosophy of cognition, Musholt proposes a model for the gradual transition from self-related information implicit in the nonconceptual content of perception and other forms of experience to the explicit representation of the self in conceptual thought. A crucial part of this model is an analysis of the relationship between self-consciousness and intersubjectivity. Self-consciousness and awareness of others, Musholt argues, are two sides of the same coin. -/- After surveying the philosophical problem of self-consciousness, the notion of nonconceptual content, and various proposals for the existence of nonconceptual self-consciousness, Musholt argues for a non-self-representationalist theory, according to which the self is not part of the representational content of perception and bodily awareness but part of the mode of presentation. She distinguishes between implicitly self-related information and explicit self-representation, and describes the transitions from the former to the latter as arising from a complex process of self–other differentiation. By this account, both self-consciousness and intersubjectivity develop in parallel. (shrink)

A scientific explanatory project, part-whole explanation, and a kind of science, part-whole science are premised on identifying, investigating, and using parts and wholes. In the biological sciences, mechanistic, structuralist, and historical explanations are part-whole explanations. Each expresses different norms, explananda, and aims. Each is associated with a distinct partitioning frame for abstracting kinds of parts. These three explanatory projects can be complemented in order to provide an integrative vision of the whole system, as is shown for a detailed case study: (...) the tetrapod limb. My diagnosis of part-whole explanation in the biological sciences as well as in other domains exploring evolved, complex, and integrated systems (e.g., psychology and cognitive science) cross-cuts standard philosophical categories of explanation: causal explanation and explanation as unification. Part-whole explanation is itself one essential aspect of part-whole science. (shrink)

Scientific inquiry has led to immense explanatory and technological successes, partly as a result of the pervasiveness of scientific theories. Relativity theory, evolutionary theory, and plate tectonics were, and continue to be, wildly successful families of theories within physics, biology, and geology. Other powerful theory clusters inhabit comparatively recent disciplines such as cognitive science, climate science, molecular biology, microeconomics, and Geographic Information Science (GIS). Effective scientific theories magnify understanding, help supply legitimate explanations, and assist in formulating predictions. Moving from their (...) knowledge-producing representational functions to their interventional roles (Hacking 1983), theories are integral to building technologies used within consumer, industrial, and scientific milieus. -/- This entry explores the structure of scientific theories from the perspective of the Syntactic, Semantic, and Pragmatic Views. Each of these views answers questions such as the following in unique ways. What is the best characterization of the composition and function of scientific theory? How is theory linked with world? Which philosophical tools can and should be employed in describing and reconstructing scientific theory? Is an understanding of practice and application necessary for a comprehension of the core structure of a scientific theory? How are these three views ultimately related? (shrink)

Map making and, ultimately, _map thinking_ is ubiquitous across literature, cosmology, mathematics, psychology, and genetics. We partition, summarize, organize, and clarify our world via spatialized representations. Our maps and, more generally, our representations seduce and persuade; they build and destroy. They are the ultimate record of empires and of our evolving comprehension of our world. This book is about the promises and perils of map thinking. Maps are purpose-driven abstractions, discarding detail to highlight only particular features of a territory. By (...) preserving certain features at the expense of others, they can be used to reinforce a privileged position. -/- _When Maps Become the World_ shows us how the scientific theories, models, and concepts we use to intervene in the world function as maps, and explores the consequences of this, both good and bad. We increasingly understand the world around us in terms of models, to the extent that we often take the models for reality. Winther explains how in time, our historical representations in science, in cartography, and in our stories about ourselves replace individual memories and become dominant social narratives—they become reality, and they can remake the world. -/- Available on The University of Chicago Press website, etc. (shrink)

Scientists use models to understand the natural world, and it is important not to conflate model and nature. As an illustration, we distinguish three different kinds of populations in studies of ecology and evolution: theoretical, laboratory, and natural populations, exemplified by the work of R.A. Fisher, Thomas Park, and David Lack, respectively. Biologists are rightly concerned with all three types of populations. We examine the interplay between these different kinds of populations, and their pertinent models, in three examples: the notion (...) of “effective” population size, the work of Thomas Park on /Tribolium/ populations, and model-based clustering algorithms such as /Structure/. Finally, we discuss ways to move safely between three distinct population types while avoiding confusing models and reality. (shrink)

How did psychoanalysis attain its prominent cultural position? How did it eclipse rival psychologies and psychotherapies, such that it became natural to bracket Freud with Copernicus and Darwin? Why did Freud 'triumph' to such a degree that we hardly remember his rivals? This book reconstructs the early controversies around psychoanalysis and shows that rather than demonstrating its superiority, Freud and his followers rescripted history. This legend-making was not an incidental addition to psychoanalytic theory but formed its core. Letting the primary (...) material speak for itself, this history demonstrates the extraordinary apparatus by which this would-be science of psychoanalysis installed itself in contemporary societies. Beyond psychoanalysis, it opens up the history of the constitution of the modern psychological sciences and psychotherapies, how they furnished the ideas which we have of ourselves and how these became solidified into indisputable 'facts'.

In 1955 the fi rst Danish chair in education was set up at the University of Copenhagen and Knud Grue-Sørensen – Doctor of Philosophy – became appointed as holder of the chair. In 1965 the chair had an institute,Institute of Educational Th eory, connected to it.The following deals with the nineteen years in which Grue-Sørensen worked as a professor of educationat the university. The assumption upon which the essay rests is that his main ambition during theseyears was to lay the (...) scientific foundations of educational theory as a an autonomous discipline in its own rightnext to neighbouring disciplines like, say, psychology and sociology. Although well acquainted with those disciplineshe nevertheless consequently subjected their research results to critical examination of their relevanceto the solution of educational problems. Infl uenced in general by a strong interest in language matters andby English philosophers in particular he practiced a method of ordinarylanguage analysis and applied it to bring to light important language nuances often overlooked in empiricalresearch. Convincingly, he demonstrated this method in his analysis of the concept of learning. (shrink)

Two families of mathematical methods lie at the heart of investigating the hierarchical structure of genetic variation in Homo sapiens: /diversity partitioning/, which assesses genetic variation within and among pre-determined groups, and /clustering analysis/, which simultaneously produces clusters and assigns individuals to these “unsupervised” cluster classifications. While mathematically consistent, these two methodologies are understood by many to ground diametrically opposed claims about the reality of human races. Moreover, modeling results are sensitive to assumptions such as preexisting theoretical commitments to certain (...) linguistic, anthropological, and geographic human groups. Thus, models can be perniciously reified. That is, they can be conflated and confused with the world. This fact belies standard realist and antirealist interpretations of “race,” and supports a pluralist conventionalist interpretation. (shrink)

Geographic Information Science (GIS) is an interdisciplinary science aiming to detect and visually represent patterns in spatial data. GIS is used by businesses to determine where to open new stores and by conservation biologists to identify field study locations with relatively little anthropogenic influence. Products of GIS include topographic and thematic maps of the Earth’s surface, climate maps, and spatially referenced demographic graphs and charts. In addition to its social, political, and economic importance, GIS is of intrinsic philosophical interest due (...) to its methodological richness and because it is an instructive analogue to other sciences. This chapter works towards a philosophy of GIS and cartography, or PGISC. In particular, it examines practices of classifying geographic space, objects, and relations. By focusing on the use of natural kinds in data modeling and map generalization practices, I show how the making and using of kinds is contextual, fallible, plural, and purposive. (shrink)

Mary Midgley, Iris Murdoch, Gertrude Anscombe and Philippa Foot studied together in Oxford during the war, at a time when most of the men had left the university, leaving it to them for themselves. These unique circumstances where decisive for the fact that they all went on to become successful philosophers and were able to develop their own original philosophical theories, opposing the philosophical dogmas of their time, Midgley later wrote. This claim is the point of departure for this article. (...) It has three purposes: First I try to say something about the circumstances that made it possible to develop such alternatives, and second, I try to say something about what they consist in. Finally, I ask what this story can teach us about inclusion of women in philosophy today. (shrink)

A. W. F. Edwards is one of the most influential mathematical geneticists in the history of the discipline. One of the last students of R. A. Fisher, Edwards pioneered the statistical analysis of phylogeny in collaboration with L. L. Cavalli-Sforza, and helped establish Fisher's concept of likelihood as a standard of statistical and scientific inference. In this book, edited by philosopher of science Rasmus Grønfeldt Winther, Edwards's key papers are assembled alongside commentaries by leading scientists, discussing Edwards's influence on (...) their own research and on thinking in their field overall. In an extensive interview with Winther, Edwards offers his thoughts on his contributions, their legacy, and the context in which they emerged. This book is a resource both for anyone interested in the history and philosophy of genetics, statistics, and science, and for scientists seeking to develop new algorithmic and statistical methods for understanding the genetic relationships between and among species both extant and extinct.

All eyes are turned towards genomic data and models as the source of knowledge about whether human races exist or not. Will genomic science make the final decision about whether racial realism (e.g., racial population naturalism) or anti-realism (e.g., racial skepticism) is correct? We think not. We believe that the results of even our best and most impressive genomic technologies underdetermine whether bio-genomic races exist, or not. First, different sub-disciplines of biology interested in population structure employ distinct concepts, aims, measures, (...) and models, producing cross-cutting categorizations of population subdivisions rather than a single, universal bio-genomic concept of "race." Second, within each sub-discipline (e.g., conservation biology, phylogenetics), genomic results are consistent with, and map multiply to, racial realism and anti-realism. Indeed, racial ontologies are constructed conventionally, rather than discovered. We thus defend a /constructivist conventionalism/ about bio-genomic racial ontology. Choices and conventions must always be made in identifying particular kinds of groups. Political agendas, social programs, and moral questions premised on the existence of naturalistic race must accept that no scientifically grounded racial ontology is forthcoming, and adjust presumptions, practices, and projects accordingly.

One of the reasons why GMOs have met public resistance in the past is that they are perceived as “unnatural”. The basis for this claim has, in part, to do with crossing species boundaries, which is considered morally objectionable. The emergence of CRISPR is sometimes argued to be an ethical game-changer in this regard since it does not require the insertion of foreign genes. Based on an empirical bioethics study including individual interviews and focus groups with laypeople and other stakeholders, (...) this article analyses the normative role of appeals to naturalness in discussions about the moral acceptability of using CRISPR in salmon farming. It discusses two dimensions of naturalness found in the material– living by species-specific nature and being unaffected by humans– and argues that these dimensions put down criteria for the application of CRISPR that lead to a conflict between our moral duties towards the farmed salmon and those we hold towards the wild salmon as a threatened species. It also points to a paradox which is likely to gain traction with further climate change and biodiversity loss, namely that while nature, understood as that which is unaffected by humans, is presented as an ideal, conserving nature in its pristine state may rely on technology and human intervention.

A map is not its territory. Taking a map too seriously may lead to pernicious reification: map and world are conflated. As one family of cases of such reification, I focus on maps exuding the omphalos syndrome, whereby a centred location on the map is taken to be the world navel of, for instance, an empire. I build on themes from my book _When Maps Become the World_, in which I analogize scientific theories to maps, and develop the tools of (...) assumption archaeology and integration platforms. Here I argue that excavating assumptions helps fill cartographic silences, showing the limitations of perspectives often at war. Furthermore, integrating perspectives permits resisting imperial central or master images. A worthwhile future project would be a repository of world-navel maps, critically annotated with cultural context and imperial information. Mutual understanding may result from such an integration platform, perhaps implemented online or in a museum. (shrink)

The genome editing technology CRISPR is described as a technological game-changer because of its flexibility and precision, and as an ethical game-changer due to its ability to engineer traits in living organisms without crossing species, avoiding a significant objection to genetically modified organisms (GMOs). In salmon farming, applications of CRISPR in breeding hold the promise of handling environmental and fish welfare challenges yet require social acceptance. Adopting an empirical bioethics framework, this stakeholder interview study shows that respecting species borders is (...) important, but not decisive, for acceptance among Norwegian stakeholders. The main objections are based on moral reflections about technology use and outcomes. These reflections combine principles and pragmatic deliberations of moral costs and benefits, suggesting that CRISPR applications with environmentally and ethically significant benefits can be socially acceptable. This indicates that the game-changing potential of CRISPR relies on the characteristics of the editing and the context in which the application takes place. (shrink)

In today’s pandemic, many countries have experienced shortages of medical resources and many healthcare providers have often been faced with dramatic decisions about how to allocate beds, intensive care, or ventilators. Despite recognizing the need for triage, responses are not the same everywhere, and opinions and practices differ around what guidelines should be used, how they should be implemented, and who should ultimately decide. To some extent, triage issues reflect community values, revealing a given society’s moral standards and ideals. Our (...) goal is to study two countries which share many common features—Italy and France—as they deal with the pandemic, revealing the moral organization of medicine and healthcare, the power structures, and the nature of the disruptions in each context.

This year’s topic is “Genomics and Philosophy of Race.” Different researchers might work on distinct subsets of the six thematic clusters below, which are neither mutually exclusive nor collectively exhaustive: (1) Concepts of ‘Race’; (2) Mathematical Modeling of Human History and Population Structure; (3) Data and Technologies of Human Genomics; (4) Biological Reality of Race; (5) Racialized Selves in a Global Context; (6) Pragmatic Consequences of ‘Race Talk’ among Biologists.

The ontology of race is replete with moral, political, and scientific implications. This book chapter surveys proposals about the reality of race, distinguishing among three levels of analysis: biogenomic, biological, and social. The relatively homogeneous structure of human genetic variation casts doubt upon the practice of postulating distinct biogenomic races that might be mapped onto socially recognized race categories.

It is a widely accepted assumption within the philosophy of mind and psychology that our ability for complex social interaction is based on the mastery of a common folk psychology, that is to say that social cognition consists in reasoning about the mental states of others in order to predict and explain their behavior. This, in turn, requires the possession of mental-state concepts, such as the concepts belief and desire. In recent years, this standard conception of social cognition has been (...) called into question by proponents of so-called ‘direct-perception’ approaches to social cognition and by those who argue that the ‘received view’ implies a degree of computational complexity that is implausible. In response, it has been argued that these attacks on the classical view of social cognition have no bite at the subpersonal level of explanation, and that it is the latter which is at issue in the debate in question. In this paper, I critically examine this response by considering in more detail the distinction between personal and subpersonal level explanations. There are two main ways in which the distinction has been developed. I will argue that on either of these, the response proposed by defenders of the received view is unconvincing. This shows that the dispute between the standard conception and alternative approaches to mindreading is a dispute concerning personal-level explanations - what is at stake in the debate between proponents of the classical view of social cognition and their critics is how we, as persons, navigate our social world. I will conclude by proposing a pluralistic approach to social cognition, which is better able to do justice to the multi-faceted nature of our social interactions as well as being able to account for recent empirical findings regarding the social cognitive abilities of young infants.

Corpus surveys have shown that the exact forms with which idioms are realized are subject to variation. We report a rating experiment showing that such alternative realizations have varying degrees of acceptability. Idiom variation challenges processing theories associating idioms with fixed multi-word form units, fixed configurations of words, or fixed superlemmas, as they do not explain how it can be that speakers produce variant forms that listeners can still make sense of. A computational model simulating comprehension with naive discriminative learning (...) is introduced that provides an explanation for the different degrees of acceptability of several idiom variant types. Implications for multi-word units in general are discussed. (shrink)

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.

Philosophy can shed light on mathematical modeling and the juxtaposition of modeling and empirical data. This paper explores three philosophical traditions of the structure of scientific theory—Syntactic, Semantic, and Pragmatic—to show that each illuminates mathematical modeling. The Pragmatic View identifies four critical functions of mathematical modeling: (1) unification of both models and data, (2) model fitting to data, (3) mechanism identification accounting for observation, and (4) prediction of future observations. Such facets are explored using a recent exchange between two groups (...) of mathematical modelers in plant biology. Scientific debate can arise from different modeling philosophies. (shrink)

Knowledge of factors that trigger human response to climate change is crucial for effective climate change policy communication. Climate change has been claimed to have low salience as a risk issue because it cannot be directly experienced. Still, personal factors such as strength of belief in local effects of climate change have been shown to correlate strongly with responses to climate change and there is a growing literature on the hypothesis that personal experience of climate change explains responses to climate (...) change. Here we provide, using survey data from 845 private forest owners operating in a wide range of bio-climatic as well as economic-social-political structures in a latitudinal gradient across Europe, the first evidence that the personal strength of belief and perception of local effects of climate change, highly significantly explain human responses to climate change. A logistic regression model was fitted to the two variables, estimating expected probabilities ranging from 0.07 to 0.81 for self-reported adaptive measures taken. Adding socio-demographic variables improved the fit, estimating expected probabilities ranging from 0.022 to 0.91. We conclude that to explain and predict adaptation to climate change, the combination of personal experience and belief must be considered. (shrink)

The dangers of character reification for cladistic inference are explored. The identification and analysis of characters always involves theory-laden abstraction—there is no theory-free “view from nowhere.” Given theory-ladenness, and given a real world with actual objects and processes, how can we separate robustly real biological characters from uncritically reified characters? One way to avoid reification is through the employment of objectivity criteria that give us good methods for identifying robust primary homology statements. I identify six such criteria and explore each (...) with examples. Ultimately, it is important to minimize character reification, because poor character analysis leads to dismal cladograms, even when proper phylogenetic analysis is employed. Given the deep and systemic problems associated with character reification, it is ironic that philosophers have focused almost entirely on phylogenetic analysis and neglected character analysis.

____Remembering Anna O.__ offers a devastating examination of the very foundations of psychoanalytic theory and practice, which was born with the publication of Breuer and Freud's ____Studies on Hysteria__ in 1895. Breuer described the case of Anna O., a young woman afflicted with a severe hysteria whom he had cured of her symptoms by having her recount under hypnosis the traumatic events that precipitated her illness. Drawing on the most recent Freud scholarship and on long-secret documents, Borch-Jacobsen demonstrates, however, (...) that Anna O. was never cured by Breuer's "talking cure" and that both Breuer and Freud knowingly falsified the historical record. Borch-Jacobsen points out the numerous inconsistencies in Breuer's account that suggests that Anna O.'s symptoms were simulated to meet Breuer's theoretical expectations and that her famed "reminiscences" were in fact fictitious memories induced by Breuer in the course of a hypnotic treatment.

Should we think of our universe as law-governed and “clockwork”-like or as disorderly and “soup”-like? Alternatively, should we consciously and intentionally synthesize these two extreme pictures? More concretely, how deterministic are the postulated causes and how rigid are the modeled properties of the best statistical methodologies used in the biological and behavioral sciences? The charge of this entry is to explore thinking about causation in the temporal evolution of biological and behavioral systems. Regression analysis and path analysis are simply explicated (...) with reference to a thought experiment of painting three universes (clockwork, soup, and conscious) useful for imagining our actual universe.

The ocean terrain spanning the globe is vast and complex—far from an immense flat plain of mud. To map these depths accurately and wisely, we must understand how cartographic abstraction and generalization work both in analog cartography and digital GIS.

The role of measurement and abstraction—as well as of political and economic power, and (...) sexual and personal bias—in these sciences is illustrated by the biographies of Marie Tharp and Bruce Heezen, whose mapping of the Mid-Atlantic Ridge precipitated a paradigm shift in geology.

In recent years, phenomenologically informed philosophers, psychologists and psychiatrists have attempted to import philosophical notions associated with the self into the empirical study of pathological experience. In particular, so-called ipseity disturbances have been put forward as generative of symptoms of schizophrenia, and several attempts have been made to operationalize and measure kinds and degrees of ipseity disturbances in schizophrenia. However, we find that this work faces challenges caused by the fact that the notion of ipseity is used ambiguously, both in (...) the philosophical and in the empirical discussion, and the methods employed to operationalize ipseity often portray a rather different understanding of the notion from that found in the literature that is cited as providing the philosophical foundation for the studies in question. In particular, according to the definitions found in the philosophical literature, while being phenomenologically available, the self is not represented in ipseity. However, when it comes to the empirical study of ipseity and its disturbances, the object of investigation is often a kind of explicit self-representation. As a result, it is unclear whether different researchers are really talking about the same thing. Future progress in this area will require more careful conceptual distinctions; the present article aims to contribute to this task. (shrink)
