The topic of colour vision is one that integrates research from psychology, neuroscience, biology, ophthalmology, physics, and genetics. How do we make sense of colour in the world, and how has such an ability evolved in humans? How does the brain interpret colour images? Do men discriminate colours differently from women? Why do some people have problems perceiving colours? Mollon, Pokorny, and Knoblauch are leading authorities on this topic, and together they have brought together a stellar list of contributors, (...) encompassing all these fields. (shrink)

This study explores the concept of rhythm and the relation of rhythm to the environment. Rhythm is not conceived of simply as a linear sequence of beats and pauses, but as a formative dynamic principle operating in all living systems. Following the rhythmanalysis of H. Levebvre and C. Regulier, phenomenological analyses of rhythm in Schutz and Richir, and a deleuzian processual approach to rhythm and milieu, this study attempts to address rhythm in terms of polyrhythmic bundles, which may be in (...) states of eurhythmia or arrhythmia. Specifically, the study focuses on three types of polyrhythmic arrangements – individual organism, garden, and city, on which it shows several types of rhythmic formations and rhythmic principles, whose interplay or discrepancy determines the formation of distinct types of living environment.

Jan Patočka's “Galileo Galilei and the End of the Ancient Cosmos” was initially published in the popular science journal Vesmír, 33 (1954), no. 1, pp. 27–29. The year before, there had been published in the same journal, under the general heading “On the Development of the Ideas of Natural Science,” a series of Patočka’s articles, including “The First Critics of Aristotelianism” [Vesmír 32 (1953), no. 7, pp. 254–256]; “The Breakdown of Aristotle’s Dynamics and the Prelude to Modern Mechanicism” (ibid., no. (...) 8, pp. 285–287); “Intermezzo on the Threshold of Modern Science: Cusanus and Comenius” (ibid., no. 9, pp. 322–325). This series had been introduced by yet another text: “Aristotle’s Philosophical Natural Science” [Vesmír 32 (1953), no. 3, pp. 102–105]. A last short essay on the theme of the birth of modern natural science—“On the Significance of Francis Bacon of Verulam” [Vesmír 40 (1961), no. 5, pp. 152, 155, and no. 6, pp. 186–188]—followed several years later.

Posthumanism is presented in this text as a problem and analyzed from a conceptual level, which includes other related concepts such as anthropocentrism, humanism and the Anthropocene, and especially at the level of prefixes, i.e. the expressions posthumanism, transhumanism, dehumanization, inhumanity and inhuman, pre-human or subhuman. The problem of posthumanism is understood here in the context of the interregnum as a time of transition, multiple crises and the transformation of the human into the inhuman. The problem of posthumanism is grasped (...) as a problem of philosophical anthropology related to the question of humankind’s place in the cosmos, as an ontological problem associated with the relationship between identity and hybridity, and as an ethical-political problem associated with the question of human technological domination and control. Posthumanism is seen as an opportunity to formulate a picture of transversal thinking. (shrink)

Public extension services play a key role in the implementation of strategies for rural development based on the sustainable management of natural resources. However, the sector suffers from restricted financial and human resources. Using experiences from participatory action research, a strategy for rural extension in the Amazon was defined to increase the efficiency and the relevance of external support for local resource users. This strategy considered activities initiated and coordinated by local people. Short-term facilitation visits provided continuous external support for (...) the purpose of establishing locally based planning and learning mechanisms. In collaboration with the municipality of Muaná in the Eastern Amazon, the strategy was tested in two traditional communities – Monte Moriat and Boa Esperança. Both communities recognized as most important the need to reduce their dependence on açaí (Euterpe oleracea Mart.), the principal source of food and income. This forest resource has been overexploited, seriously affecting açaí stands and diminishing the forest benefits fundamental for survival. Two local groups decided to raise chickens as a way to reduce nutritional problems and as an alternative source of income. Supported by monthly, short-term planning and evaluation visits, the groups managed to achieve significant progress in their endeavor. The groups identified (1) the control of decision-making and information, and (2) the absence of external obligations to be the greatest advantages of the development initiative. The study confirmed the potential of participatory strategies for public extension in the Amazon. Special attention was given to realistically define the role of forests for local development. However, drastic measures are necessary to smooth the way for real participation in governmental and non-governmental organizations acting in the Brazilian Amazon. (shrink)

A family of recent externalist approaches in philosophy of mind argues that our psychological capacities are synchronically and diachronically “scaffolded” by external resources. I consider how these “scaffolded” approaches might inform debates in phenomenological psychopathology. I first introduce the idea of “affective scaffolding” and make some taxonomic distinctions. Next, I use schizophrenia as a case study to argue—along with others in phenomenological psychopathology—that schizophrenia is fundamentally a self-disturbance. However, I offer a subtle reconfiguration of these approaches. I argue that schizophrenia (...) is not simply a disruption of ipseity or minimal self-consciousness but rather a disruption of the scaffolded self, established and regulated via its ongoing engagement with the world and others. I conclude by considering how this scaffolded framework indicates the need to consider new forms of intervention and treatment. (shrink)

Until recently, philosophers and psychologists conceived of emotions as brain- and body-bound affairs. But researchers have started to challenge this internalist and individualist orthodoxy. A rapidly growing body of work suggests that some emotions incorporate external resources and thus extend beyond the neurophysiological confines of organisms; some even argue that emotions can be socially extended and shared by multiple agents. Call this the extended emotions thesis. In this article, we consider different ways of understanding ExE in philosophy, psychology, and the (...) cognitive sciences. First, we outline the background of the debate and discuss different argumentative strategies for ExE. In particular, we distinguish ExE from cognate but more moderate claims about the embodied and situated nature of cognition and emotion. We then dwell upon two dimensions of ExE: emotions extended by material culture and by the social factors. We conclude by defending ExE against some objections and point to desiderata for future research. (shrink)

This book discusses problems of conceptual analysis as well as normative issues of vital contemporary concern.

The problem of other minds has a distinguished philosophical history stretching back more than two hundred years. Taken at face value, it is an epistemological question: it concerns how we can have knowledge of, or at least justified belief in, the existence of minds other than our own. In recent decades, philosophers, psychologists, neuroscientists, anthropologists and primatologists have debated a related question: how we actually go about attributing mental states to others (regardless of whether we ever achieve knowledge or rational (...) justification in this domain). Until the mid-nineties, the latter debate – which sometimes goes under the name of the “mindreading” debate – was characterized by a fairly clear-cut opposition between two theoretical outlooks: “theory-theory” (TT) and “simulation theory” (ST). Theory-theorists typically argued that we attribute mental states to others on the basis of a “theory of mind” that is either constructed in early infancy and subsequently revised and modified (Gopnik 1996), or else is the result of maturation of innate mindreading “modules” (Baron-Cohen 1995).

The extended mind thesis (EM) asserts that some cognitive processes are (partially) composed of actions consisting of the manipulation and exploitation of environmental structures. Might some processes at the root of social cognition have a similarly extended structure? In this paper, I argue that social cognition is fundamentally an interactive form of space management—the negotiation and management of ‘‘we-space”—and that some of the expressive actions involved in the negotiation and management of we-space (gesture, touch, facial and whole-body expressions) drive basic (...) processes of interpersonal understanding and thus do genuine social-cognitive work. Social interaction is a kind of extended social cognition, driven and at least partially constituted by environmental (non-neural) scaffolding. Challenging the Theory of Mind paradigm, I draw upon research from gesture studies, developmental psychology, and work on Moebius Syndrome to support this thesis. (shrink)

The multiverse view in set theory, introduced and argued for in this article, is the view that there are many distinct concepts of set, each instantiated in a corresponding set-theoretic universe. The universe view, in contrast, asserts that there is an absolute background set concept, with a corresponding absolute set-theoretic universe in which every set-theoretic question has a definite answer. The multiverse position, I argue, explains our experience with the enormous range of set-theoretic possibilities, a phenomenon that challenges the universe (...) view. In particular, I argue that the continuum hypothesis is settled on the multiverse view by our extensive knowledge about how it behaves in the multiverse, and as a result it can no longer be settled in the manner formerly hoped for.

Comparative study of wall paintings in churches dedicated to St Clement in Stará Boleslav and Rome reveals the wide international networking of contemporary agents in artistic transfer. The importance of late twelfth-century wall paintings in St Clement’s in Stará Boleslav – among Bohemia’s foremost medieval monuments – is underscored by their close proximity to the place of the martyrdom and the center of the cult of the country’s patron, St Wenceslas. The Bohemian church’s consecration echoes the Cyril and Methodius mission, (...) resonating with the transfer of St Clement’s relics from the Crimea to Central Europe, then to the Basilica of San Clemente in Rome. The frescoes in the Roman basilica’s lower church have been recognized as an important source for the concept of the paintings. The extensive, and iconographically exceptional, image cycle of St Clement’s life was commissioned by a high-ranking cleric, possibly the Salzburg archbishop, Adalbert of the Přemyslid family. The recent fresco restoration survey has yielded insights into the painting technique and will become the basis for the future rescue and rehabilitation of the Romanesque church’s wall decoration.

Loneliness is a near-universal experience. It is particularly common for individuals with (so-called) psychopathological conditions or disorders. In this paper, we explore the experiential character of loneliness, with a specific emphasis on how social goods are experienced as absent in ways that involve a diminished sense of agency and recognition. We explore the role and experience of loneliness in three case studies: depression, anorexia nervosa, and autism. We demonstrate that even though experiences of loneliness might be common to many psychopathologies, (...) these experiences nevertheless have distinctive profiles. Specifically, we suggest that: (i) loneliness is often a core characteristic of depressive experience; (ii) loneliness can drive, and even cement, disordered eating practices and anorectic identity in anorexia nervosa; iii) loneliness is neither a core characteristic of autism nor a driver but is rather commonly experienced as stemming from social worlds, environments, and norms that fail to accommodate autistic bodies and their distinctive forms of life. We aim to do justice to the pervasiveness of loneliness in many — if not all — psychopathologies, while also highlighting the need to attend to psychopathology-specific experiences of loneliness, agency, and (non-)recognition.

This book traces how such a seemingly immutable idea as measurement proved so malleable when it collided with the subject matter of psychology. It locates philosophical and social influences reshaping the concept and, at the core of this reshaping, identifies a fundamental problem: the issue of whether psychological attributes really are quantitative. It argues that the idea of measurement now endorsed within psychology actually subverts attempts to establish a genuinely quantitative science and it urges a new direction. It relates views (...) on measurement by thinkers such as Holder, Russell, Campbell and Nagel to earlier views, like those of Euclid and Oresme. Within the history of psychology, it considers contributions by Fechner, Cattell, Thorndike, Stevens and Suppes, among others. It also contains a non-technical exposition of conjoint measurement theory and recent foundational work by leading measurement theorist R. Duncan Luce. (shrink)

I shall be concerned in this paper with some philosophical puzzles raised by so-called “wrongful life” suits. These legal actions are obviously of great interest to lawyers and physicians, but philosophers might have a kind of professional interest in them too, since in a remarkably large number of them, judges have complained that the issues are too abstruse for the courts and belong more properly to philosophers and theologians. The issues that elicit this judicial frustration are those that require the (...) application to border-line cases of such philosophically interesting concepts as acting, causing, and the one that especially interests me, harming. I first became interested in the concept of harming in my work on the moral limits of the criminal law, where I had to come to terms with John Stuart Mill's famous “harm principle”–the principle that it is always a good reason in support of a criminal prohibition, indeed, the only legitimate reason, that it will prevent harm to persons other than the actor. I could not very well criticize that principle until I decided what the word “harm” must mean in its formulation. I gave what I took to be the requisite analysis of harm in my book Harm to Others. Here I wish to improve that analysis, examine its implications for civil as well as criminal liability, and test it on conceptually hard cases, especially cases of prenatal harming, that is, cases in which the wrongful causative conduct occurs before the victim's birth, and the harmed state that is its upshot consists in being born in an impaired condition.

Some recent developments in Artificial Intelligence—especially the use of machine learning systems, trained on big data sets and deployed in socially significant and ethically weighty contexts—have led to a number of calls for “transparency”. This paper explores the epistemological and ethical dimensions of that concept, as well as surveying and taxonomising the variety of ways in which it has been invoked in recent discussions. Whilst “outward” forms of transparency may be straightforwardly achieved, what I call “functional” transparency about the inner (...) workings of a system is, in many cases, much harder to attain. In those situations, I argue that contestability may be a possible, acceptable, and useful alternative so that even if we cannot understand how a system came up with a particular output, we at least have the means to challenge it.

I argue for an enactive account of musical experience — that is, the experience of listening ‘deeply’(i.e., sensitively and understandingly) to a piece of music. The guiding question is: what do we do when we listen ‘deeply’to music? I argue that these music listening episodes are, in fact, doings. They are instances of active perceiving, robust sensorimotor engagements with and manipulations of sonic structures within musical pieces. Music is thus experiential art, and in Nietzsche’s words, ‘we listen to music with (...) our muscles’. This paper attempts to explicate and defend this claim. First, I discuss enactive approaches to consciousness and cognition generally. Next, I apply an enactive model of perceptual consciousness to the experience of listening to music. To clarify what is at stake, I use Peter Kivy’s ‘enhanced formalism’ as a philosophical foil. I then look at how the animate body shapes musical experience. (shrink)

I develop Tetsurō Watsuji’s relational model of the self as “betweenness”. I argue that Watsuji’s view receives support from two case studies: solitary confinement and dementia. Both clarify the constitutive interdependence between the self and the social and material contexts of “betweenness” that define its lifeworld. They do so by providing powerful examples of what happens when the support and regulative grounding of this lifeworld is restricted or taken away. I argue further that Watsuji’s view helps see the other side (...) of this deprivation, how reconstructing aspects of betweenness is, at the same time, a reconstruction of the self. I conclude by briefly indicating further consequences of this view. (shrink)

Testimony by disabled people concerning the relationship between their experiences and overall well-being has long been an object of social scientific and humanistic study. Often discussed in terms of “the disability paradox,” these studies contrast the intuitive horribleness of certain impaired states against the testimonial evidence suggesting that people in such states do not in fact experience their lives as horrible. Explanations for why such testimonial evidence is suspect range from claims about adaptive preferences to issues of qualitative research methodology. (...) In this paper, I argue that the problem lies not with the evidence, but the intuitions in question. Using the disability paradox as a case study, I further argue against the use of the concept of intuitive horribleness in social epistemology and beyond. I contend that testimonial and hermeneutical injustices are baked into most deployments of the concept, and even if one were to justify its use in select cases, it should be accompanied with prima facie suspicion. In conclusion, I discuss the implications of this analysis for the literature on transformative experience and also for the stakes of multi-cultural, historically informed philosophical inquiry more generally.

I consider applications of “AI extenders” (Vold & Hernández-Orallo 2021) to dementia care. AI extenders are AI-powered technologies that extend minds in ways interestingly different from old-school tech like notebooks, sketch pads, models, and microscopes. I focus on AI extenders as ambiance: so thoroughly embedded into things and spaces that they fade from view and become part of a subject’s taken-for-granted background. Using dementia care as a case study, I argue that ambient AI extenders are promising because they afford richer (...) and more durable forms of multidimensional integration than do old-school extenders like Otto’s notebook. They can be tailored, in fine-grained ways along multiple timescales, to a user’s particular needs, values, and preferences — and crucially, they can do much of this self-optimizing on their own. I discuss why this is so, why it matters, and its potential impact on affect and agency. I conclude with some worries in need of further discussion. (shrink)

The COVID-19 (Coronavirus disease of 2019) pandemic has led to intense conversations about ventilator allocation and reallocation during a crisis standard of care. Multiple voices in the media and multiple state guidelines mention reallocation as a possibility. Drawing upon a range of neuroscientific, phenomenological, ethical, and sociopolitical considerations, the authors argue that taking away someone’s personal ventilator is a direct assault on their bodily and social integrity. They conclude that personal ventilators should not be part of reallocation pools and that (...) triage protocols should be immediately clarified to explicitly state that personal ventilators will be protected in all cases.

Melanomas arise from transformed melanocytes, positioned at the dermal‐epidermal junction in the basal layer of the epidermis. Melanocytes are completely surrounded by keratinocyte neighbors, with which they communicate through direct contact and paracrine signaling to maintain normal growth control and homeostasis. UV radiation from sunlight reshapes this communication network to drive a protective tanning response. However, repeated rounds of sun exposure result in accumulation of mutations in melanocytes that have been considered as primary drivers of melanoma initiation and progression. It (...) is now clear that mutations in melanocytes are not sufficient to drive tumor formation—the tumor environment plays a critical role. This review focuses on changes in melanocyte‐keratinocyte communication that contribute to melanoma initiation and progression, with a particular focus on recent mechanistic insights that lay a foundation for developing new ways to intercept melanoma development.

The aim of this essay is to situate the thought of Tetsurō Watsuji within contemporary approaches to social cognition. I argue for Watsuji’s current relevance, suggesting that his analysis of embodiment and social space puts him in step with some of the concerns driving ongoing treatments of social cognition in philosophy of mind and cognitive science. Yet, as I will show, Watsuji can potentially offer a fruitful contribution to this discussion by lending a phenomenologically informed critical perspective. This is because (...) Watsuji challenges the internalist and cognitivist presuppositions informing the currently dominant “Theory of Mind” paradigm that is driving much social cognition research. Additionally, I show that Watsuji’s alternative model is not merely confined to the realm of phenomenological description but that it also receives robust empirical support from a number of different sources. I thus hope to open up aspects of Watsuji’s thinking that have yet to be fully appreciated. (shrink)

We add texture to the conclusion of Duchon and Drake (Journal of Business Ethics, 85, 2009, 301) that extreme narcissism is associated with unethical conduct. We argue that the special features possessed by financial accounting facilitate extreme narcissism in susceptible CEOs. In particular, we propose that extremely narcissistic CEOs are key players in a recurring discourse cycle facilitated by financial accounting language and measures. Such CEOs project themselves as the corporation they lead, construct a narrative about the corporation and themselves (...) using financial accounting measures, and then reflect on how their accounting-constructed performance is perceived by stakeholders. We do not present empirical evidence about whether the use of accounting language and measures leads to unethical behaviour by extreme narcissistic CEOs — although the conclusions of Duchon and Drake (2009) suggest empirical support is probable. Rather, we focus on developing alertness to the potential for accounting, when engaged by an extremely narcissistic CEO, to be a precursor or implement of unethical behaviour. (shrink)

When firm misconduct comes to light, CEOs are often faced with difficult decisions regarding whether and how to respond to stakeholder demands as they attempt to restore their firms’ legitimacy. Prior research largely assumes that such decisions are motivated by CEOs’ calculated attempts to manage stakeholder impressions. Yet, there are likely other motives, particularly those of a morally-relevant nature, that might also be influencing CEOs’ decisions. To address this limitation, we advance moral cleansing as an alternative explanation for how and (...) why CEOs lead their firms to respond to stakeholder demands following the firm’s misconduct and, in turn, whether they can successfully restore their firm’s legitimacy. In the context of firm misconduct, moral cleansing motives reflect CEOs’ desire to restore their threatened moral self-image resulting from the misconduct. We theorize that a CEO’s moral cleansing motives increase the likelihood that their firm will engage in a series of reparative responses that can restore the firm’s legitimacy (i.e., discovery, explanation, penance, and rehabilitation). In addition, we explicate the unique implications of CEOs’ moral cleansing in a post-misconduct context by theorizing how such motives may simultaneously improve one form of their firms’ legitimacy while hindering another. Specifically, we theorize that CEOs’ moral cleansing motives increase (decreases) the authenticity (strategic cognition) of their firm responses, which strengthens (weakens) the effectiveness of those responses on the firms’ ability to restore its moral (pragmatic) legitimacy with stakeholders. We conclude with a discussion of the implications of this work. (shrink)

I offer an account of the ontology of emotions and their expressions, drawing some morals for the view that we can perceive others' emotions in virtue of seeing their expressions.

Experimental taxonomy was a diverse area of research, and botanists who helped develop it were motivated by a variety of concerns. While experimental taxonomy was never totally a taxonomic enterprise, improvement in classification was certainly one major motivation behind the research. Hall's and Clements' belief that experimental methods added more objectivity to classification was almost universally accepted by experimental taxonomists. Such methods did add a new dimension to taxonomy — a dimension that field and herbarium studies, however rigorous, could not (...) duplicate. Nonetheless, experimental techniques were never completely divorced from traditional taxonomic methods. In practice, all experimental taxonomists employed a combination of descriptive and experimental methods. Most researchers freely acknowledged a debt to traditional taxonomy. Furthermore, the greater rigor of twentieth-century taxonomy was not due entirely to experimentalism. Both the experimental and descriptive aspects of taxonomy were improved by the increased use of quantitative methods, particularly statistics.52From the beginning, a number of experimental taxonomists were interested primarily in classification. But many approached their research from fields other than taxonomy. These botanists were concerned primarily with ecological and genetic problems rather than with classification. There is little indication that they drew a sharp distinction: for example, taxonomic and cytogenetic conclusions were interwoven in Babcock and Stebbins' 1938 study of Crepis 53 (this was even more true of Babcock's final mongraph on the genus, published in 1947). Similarly, the extensive series of monographs, “Experimental Studies on the Nature of Species,” initiated by the Carnegie Institution group in 1940 combined ecological, cytogenetic, and taxonomic conclusions. Indeed, the significance of the major projects completed by experimental taxonomists was largely due to the fact that they were comprehensive studies rather than strictly taxonomic or cytogenetic.In a general sense, the primary motivation behind much of experimental taxonomy was evolutionary. Beginning in the second decade of the century Hall and Clements exhorted taxonomists to take an explicitly evolutionary perspective on research. Hall undoubtedly spoke for the majority of experimental taxonomists when he stated, “If there be anything at all to organic evolution, then taxonomy is dealing with the products of evolution and it is this that gives to taxonomy both its highest mission and its greatest responsibility.”54Aside from a common interest in evolution, however, the theoretical orientations of experimental taxonomists were varied. This diversity is strikingly illustrated by the evolutionary views of members of the Carnegie Institution research group. Experimental taxonomy was initiated by Clements as one aspect of his Lamarckian study of adaptation and speciation. In contrast, Hall's research was inspired by a broad concern for evolutionary problems. Hall rarely referred to specific evolutionary mechanisms; rather, he applied a general conception of evolutionary processes to deduce phylogenetic relationships. His later associates at the Carnegie Institution explicitly dissociated themselves from Clements' theoretical framework. The neo-Darwinian interpretations of adaptation and speciation presented by Clausen, Keck, and Hiesey could hardly have been more different than those of Clements. However, this major shift in theoretical orientation should not obscure significant similarities between the research of Clements and later Carnegie workers. In terms of research problems and methodology, the first volume of “Experimental Studies on the Nature of Species” was an extension of the Clementsian research program. Clausen, Keck, and Hiesey's monograph was the mature discussion of transplant experimentation that Clements had very tentatively initiated during the first decades of the twentieth century. The bond that linked the members of the Carnegie Institution research group to experimental taxonomists in general was one of shared methodology rather than common theoretical orientation. While Clements' evolutionary views were eventually repudiated, his enthusiasm for innovative experimental methods was shared by later workers.The development of experimental taxonomy faced significant problems. During the period 1920–1950 this area of botanical research remained a hybrid discipline. The aims and scope of experimental taxonomy were never articulated in a completely unified manner. Consequently, even among experimental taxonomists, there were disagreements over the relation of their research to other botanical endeavors. Even though experimental taxonomy had close ties with general taxonomy, a number of experimental taxonomists questioned the “taxonomic” nature of their research55. Even to the extent that this hybrid discipline could be identified as a branch of taxonomy, problems arose. Taxonomists, as we have seen, were justifiably skeptical of what appeared to be a rapid influx of untested methods and ideas. Experimental taxonomists were not merely incorporating well-accepted methods from ecology and cytogenetics; during the period 1920–1950 the fields from which experimental taxonomists borrowed were themselves undergoing major theoretical and methodological changes. Despite problems and conflicts, experimental taxonomists did contribute improvements to classification. Furthermore, they made significant contributions to plant ecology and evolutionary genetics.The development of experimental taxonomy indicates that twentieth-century botanists were not necessarily isolated in naturalist and experimentalist camps. The joint session of taxonomists, cytologists, and geneticists at the 1926 International Congress of Plant Sciences indicates communication among specialists fairly early in the century. The papers and commentaries presented during this session do not reveal the hostility and intolerance that supposedly characterized encounters between experimentalists and naturalists. Nor do they suggest incompatible conceptual worlds separating geneticists and taxonomists.Discussions between taxonomists and other specialists were not limited to a single international congress. Particularly during the 1930s discussions among specialists appear to have been fairly widespread. Groups such as the Biosystematists and the Society for the Study of Systematics in Relation to General Biology served as forums for discussion among biologists from a variety of disciplines. The naturalist-experimentalist dichotomy tends to obscure the broad research interests of a number of prominent twentieth-century botanists. Most of the experimental taxonomists cannot be characterized adequately as either naturalists or experimentalists. Traditionally trained taxonomists such as Hall, Keck, and Turrill throughout their careers participated in both experimental and herbarium research. And a number of specialists in fields other than taxonomy took an active interest in taxonomic problems, not necessarily limited to experimental aspects. For example, Anderson suggested a number of innovations to make herbarium collections more amenable to statistical analysis.This historical study of experimental taxonomy indicates a different relationship between experimentalism and taxonomy than that portrayed by the naturalist-versus-experimentalist dichotomy. F. E. Clements originated experimental taxonomy as a revolt against descriptive botany. In retrospect, this revolution was not vigorously waged and was not successfully completed. Experimental taxonomy was never an entirely experimental approach to botanical research. Even the most ardent advocates of experimentalism relied heavily on methods inherited from traditional taxonomy. Moderate exponents of experimental taxonomy stressed the compatibility of experimental methods, field observation, and herbarium techniques. Attempts to fuse cytogenetics, ecology, and taxonomy during the period 1920–1950 resulted in an impressive body of research. However, this fusion constituted neither a repudiation of descriptive botany nor a complete revision of taxonomic theory of practice. (shrink)

Biologists and historians often present natural history and molecular biology as distinct, perhaps conflicting, fields in biological research. Such accounts, although supported by abundant evidence, overlook important areas of overlap between these areas. Focusing upon examples drawn particularly from systematics and molecular evolution, I argue that naturalists and molecular biologists often share questions, methods, and forms of explanation. Acknowledging these interdisciplinary efforts provides a more balanced account of the development of biology during the post-World War II era.
