The nature of scientific explanation is controversial. Some maintain that all scientific explanations have to be contrastive in nature (contrastivism). However, others argue that no scientific explanation is genuinely contrastive (non-contrastivism). In addition, a compatibilist view has been recently devloped. It is argued that the debate between contrastivism and non-contrastivism is merely a linguistic dispute rather than a genuine disagreement on the nature of scientific explanation. Scientific explanations are both contrastive and non-contrastive in some sense (compatibilism). This paper examines the (...) debate between contrastivism and non-contrastivism in scientific explanation. It begins with a critical review of the arguments for contrastivism, for non-contrastivism, and for compatibilism and concludes with some remarks on the prospect of the issue. (shrink)

The group theorist William Burnside devoted much of the last decade of his life to probability and statistics. The work led to contact with Ronald Fisher who was on his way to becoming the leading statistician of the age and with Karl Pearson, the man Fisher supplanted. Burnside corresponded with Fisher for nearly three years until their correspondence ended abruptly. This paper examines Burnside’s interactions with the statisticians and looks more generally at his work in probability and statistics.

L’histoire de la psychologie en tant que discipline autonome comporte non seulement des développements méthodologiques et institutionnels, mais aussi l’élaboration du concept même de psychologie et des représentations de sa place dans l’ordre des sciences. Si de telles représentations ne détenninent pas la constitution du champ professionnel ou la pratique concrète du psychologue, elles n’en expriment pas moins des idéaux épistémologiques et reflètent les changements qui s’opèrent au sein de la discipline. Nous donnerons d’abord une vue générale de la position (...) de la psychologie au XVIIe et au VXIIIe siècle, puis nous esquisserons l’histoire de sa place dans l’ordre des sciences de Destutt de Tracy à Jean Piaget. Après avoir été la science des sciences des classifications hiérarchiques, la psychologie s’intègre aux autres sciences dans des schémas moins linéaires, voire circulaires, sans pour autant toujours perdre la prééminence gnoséologique et pédagogique que lui attribuèrent en premier les « psychologues » du XVIIIe siècle.

This paper provides a critical review of the debate over the philosophical foundations of mixed methods research and examines the notion of philosophical foundations. It distinguishes axiology-oriented from ontology-oriented philosophical foundations. It also identifies three different senses of philosophical foundations of mixed methods research. The weak sense of philosophical foundations (e.g., pragmatism) merely allows the possibility of the integration of both quantitative and qualitative methods/data/designs. The moderate sense of philosophical foundations (e.g., transformativism) provide a good reason to use mixed methods (...) in (at least some) social scientific research. The strong sense of philosophical foundations (e.g., dialectical pluralism) justifies a normative thesis that mixed methods research should be encouraged in (at least some) social scientific research.

This paper challenges the common assumption that some phenotypic traits are quantitative while others are qualitative. The distinction between these two kinds of traits is widely influential in biological and biomedical research as well as in scientific education and communication. This is probably due to both historical and epistemological reasons. However, the quantitative/qualitative distinction involves a variety of simplifications on the genetic causes of phenotypic variability and on the development of complex traits. Here, I examine three cases from the life (...) sciences that show inconsistencies in the distinction: Mendelian traits, Mendelian diseases, and polygenic mental disorders. I show that these traits can be framed both quantitatively and qualitatively depending, for instance, on the methods through which they are investigated and on specific epistemic purposes. This suggests that the received view of quantitative and qualitative traits has a limited heuristic power—limited to some local contexts or to the specific methodologies adopted. Throughout the paper, I provide directions for framing phenotypes beyond the quantitative/qualitative distinction. I conclude by pointing at the necessity of developing a principled characterisation of what phenotypic traits, in general, are. (shrink)

This paper analyzes the development of evolutionary theory in the period from 1918 to 1932. It argues that: (i) Fisher's work in 1918 constituted a not fully satisfactory reduction of biometry to Mendelism; (ii) there was a synthesis in the 1920s but that this synthesis was mainly one of classical genetics with population genetics, with Haldane's The Causes of Evolution being its founding document; (iii) the most important achievement of the models of theoretical population genetics was to show that natural (...) selection sufficed as a mechanism for evolution; and (iv) Haldane formulated a prospective evolutionary theory in the 1920s whereas Fisher and Wright formulated retrospective theories of evolutionary history.

In this paper, I discuss the key role played by Carl G. Hempel's work on theoretical realism and scientific explanation in effecting a crucial philosophical transition between the beginning and the end of the twentieth century. At the beginning of the century, the dominant view was that science is incapable of furnishing explanations of natural phenomena; at the end, explanation is widely viewed as an important, if not the primary, goal of science. In addition to its intellectual benefits, this transition (...) has important practical consequences with respect to dealing with the global problems humans everywhere will face in the twenty-first century.

Present science policy discourse is focused on a broad concept of “techno-science” and emphasizes practical economic goals and gains. At the same time scientists are worried about the freedom of research and the autonomy of science. Half a century ago the difference between basic and applied science was widely taken for granted and autonomy was a value in high esteem. Most recent accounts of the history of science policy start abruptly from World War II, emphasize the Cold War context, and (...) neglect the pioneering role of the Soviet Union in forming todays “big science.” This paper claims that a closer look into the intellectual heritage from the early twentieth century will be helpful in navigating present issues of science policy. The “Lysenko affair” was a paradigmatic case in forming Cold War views on science and politics. (shrink)

The widespread publicity and the consequent furor created by Dr. J. B. Rhine's experiments on telepathy and clairvoyance, have been interpreted in some quarters as a call for a thorough-going revision of the entire field of psychological thought. This revision, it is held, must be in the direction of philosophic idealism, and away from previously accepted materialistic doctrines. The present paper points out the non-verifiable nature of the entities postulated by the believers in "supernormal" phenomena. Furthermore, the interpretations of contemporary (...) science held by such individuals are not in themselves on a scientific plane. Specific errors in reasoning made by workers in the field of psychical research, are presented. In short, "psychical research... cannot turn the universe into a non-material, non-objective one, on either the basis of misinterpretations of current physical thought or on the basis of its own work.".

Nous proposons dans cet article de rechercher chez les prédécesseurs de Frank Knight un peu de lumière pour éclairer sa distinction entrerisque etincertitude. D'une part, la lecture des économistes qui l'ont précédé permet de comprendre sa situation dans lapolémique sur la répartition. D'autre part, l'examen des sources philosophiques qui informent sa théorie de la connaissance conduit à analyser l'opposition risque/incertitude comme une opposition théorie de la probabilité/théorie de la connaissance (imparfaite). Le recours à l'épistémologie de Knight fait saisir en quoi (...) sa démarche philosophique le mène à conclure par l'absurde la polémique sur la répartition, et l'autorise alors à proposer une reconstruction de la théorie économique comme science des choix rationnels.

The ArgumentQuantification is not merely a strategy for describing the social and natural worlds, but a means of reconfiguring them. It entails the imposition of new meanings and the disappearance of old ones. Often it is allied to systems of experimental or administrative control, and in fact considerable feats of human organization are generally required even to create stable, reasonably standardized measures. This essay urges that the uses of quantification in science, social science, and bureaucratic social and economic policy are (...) analogous in important ways to accountancy. (shrink)

Fisher’s ‘fundamental theorem of natural selection’ is notoriously abstract, and, no less notoriously, many take it to be false. In this paper, I explicate the theorem, examine the role that it played in Fisher’s general project for biology, and analyze why it was so very fundamental for Fisher. I defend Ewens and Lessard in the view that the theorem is in fact a true theorem if, as Fisher claimed, ‘the terms employed’ are ‘used strictly as defined’. Finally, I explain the (...) role that projects such as Fisher’s play in the progress of scientific inquiry. (shrink)

Historians and biologists identify the debate between mechanists and vitalists over the nature of life itself with the arguments of Driesch, Loeb, and other prominent voices. But what if the conversation was broader and the consequences deeper for the field? Following the suspicions of Joseph Needham in the 1930s and Francis Crick in the 1960s, we deployed tools of the digital humanities to an old problem in the history of biology. We analyzed over 31,000 peer-reviewed scientific papers and learned that (...) bioexceptionalism participated in a robust discursive landscape throughout subfields of the life sciences, occupied even by otherwise unknown biologists.

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a reading (...) of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this "Galtonian" perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution. (shrink)

Standard statistical measures of strength of association, although pioneered by Pearson deliberately to be acausal, nowadays are routinely used to measure causal efficacy. But their acausal origins have left them ill suited to this latter purpose. I distinguish between two different conceptions of causal efficacy, and argue that: 1) Both conceptions can be useful 2) The statistical measures only attempt to capture the first of them 3) They are not fully successful even at this 4) An alternative definition more squarely (...) based on causal thinking not only captures the second conception, it can also capture the first one better too.

Mentalist view began to lose its standing among psychologists mainly during the first half of the twentieth century. As a result, the enthusiasm to build an objective science began to grow among behaviourists and ethologists. The rise of cognitive sciences around the 1960s, however, revived the debates over the importance of cognitive intervening variables in explaining behaviours that could not be explained by clinging solely to a pure behavioural approach. Nevertheless, even though cognitive functions in nonhuman animals have been identified (...) in many studies, attributing human mental properties to animals is still being criticized as anthropomorphism. Such anthropomorphic attributions have been considered as an open door to the return of subjective methodology. Representation of anthropomorphic attributions as scientific activities within the context of discovery as opposed to the context of justification casts a new light on this problem. The present analysis proposes that anthropomorphic attributions are formed based on top-down idiosyncratic intuitions on the cusp of hypothesis building, outside the context of scientific justification. In other words, an anthropomorphic attribution is a potential creative link between pure observations of behaviours and building testable hypotheses about cognition in the process of scientific discovery. Thus, serving a function within the context of discovery, anthropomorphism does not motivate the return of subjective methodology, simply because it is not inconsistent with the rule-governed path in the context of scientific justification.

There have been two principal paradigms for the formulation of the causal relation--logical implication and functional relationship. In this paper, I present a case for preferring the functional relationship formulation and then discuss how the functional relationship formulation may be implemented in the probabilistic case in a manner analogous to the way others have implemented the logical implication formulation in the probabilistic case. I show how the "local independence" assumption found in many models used in the behavioral and social sciences (...) is a consequence of the functional relation concept of probabilistic causality. I also discuss why causal relations are underdetermined in experience and are to be dealt with pragmatically in a hypothesis-testing framework. (shrink)

Ernst Mayr has criticised the methodology of population genetics for being essentialist: interested only in “types” as opposed to individuals. In fact, he goes so far as to claim that “he who does not understand the uniqueness of individuals is unable to understand the working of natural selection” (1982, 47). This is a strong claim indeed especially since many responsible for the development of population genetics (especially Fisher, Haldane, and Wright) were avid Darwinians. In order to unravel this apparent incompatibility (...) I want to examine the possible sources and implications of essentialism in this context and show why the kind of mathematical analysis found in Fisher's work is better seen as responsible for extending the theory of natural selection to a broader context rather than inhibiting its applicability.

The aim of this paper is to introduce the instrumental variables technique to the discussion about causal inference in econometrics. I show that it may lead to causally incorrect conclusions unless some fairly strong causal background assumptions are made, assumptions which are usually left implicit by econometricians. These assumptions are very similar to, albeit not identical with, James Woodward's definition of an ‘intervention’. I discuss similarities and differences of the two points of view and argue that—understood as a practical method (...) of causal inference—the set presented here is superior. (shrink)

This body of work is motivated by an apparent contradiction between, on the one hand, Darwin’s testimony in his autobiographical text about a supposed perceptual colour blindness before the aesthetic magnificence of natural landscapes, and, on the other hand, the last paragraph of On the Origin of Species, where he claims to perceive the forms of nature as beautiful and wonderful. My aim is to delve into the essence of the Darwinian perception of beauty in the context of the Weberian (...) concept of “disenchantment of the world”, assumed as a possible conceptual axis that enables the unravelling of the core of this contrast of perceptions. In acknowledging the theory of evolution as one of the most prominent scientific theories likely to have contributed to disenchantment, a number of questions arise: Is disenchantment compatible with aesthetic experience and sensibility before natural beauty? Was it Darwin’s disenchanted conception of the world that led him to believe he was colour blind? To answer these questions, a computer-assisted semantic analysis of lexical frequency and variability, most especially focused on aesthetic-emotional and religious or spiritual adverbs and adjectives, has been undertaken across the six editions of The Origin. The semantic analysis demonstrates that, although disenchanted, Darwin’s descriptions of, mainly, the adaptational excellence of living beings, reflect an aesthetically enriched perception of nature. It is concluded that Darwin’s perceptual colour blindness, then, might be based on a confusion rooted in the equation of equality between aesthetic sensibility in nature and the perception of its beauty as part of the vestigia Dei.

The complete system of knowledge is a standard trope of science fiction, a techno-utopian dream and an aesthetic ideal. It is Solomon’s House, the Encyclopaedia and the Museum. It is also an ideology – of Enlightenment, High Modernism and absolute governance. Far from ending the dream of a total archive, 20th-century positivist rationality brought it ever closer. From Paul Otlet’s ‘Mundaneum’ to Mass-Observation, from the Unity of Science movement to Wikipedia, the dream of universal knowledge dies hard. As a political (...) tool, the total archive encompasses population statistics, gross domestic product, indices of the Standard of Living and the international ideology of the United Nations Educational, Scientific and Cultural Organization, the World Health Organization, the free market and, most recently, Big Data. Questions of the total archive engage key issues in the philosophy of classification, the poetics of the universal, the ideology of surveillance and the technologies of information retrieval. What are the social structures and political dynamics required to sustain total archives, and what are the temporalities implied by such projects? This introduction and the articles that follow describe and place in historical context a series of concrete instances of totality. Our analysis is arranged according to four central themes: the relationship between the Archive (singular) and archives (plural); the image of the archive and the aesthetics of totality; pathologies of accumulation; and the specific historical trajectory of the total archive in the 19th and 20th centuries.

British social survey movement ‘Mass-Observation’ (M-O) was founded in 1937 by a poet, a film-maker and an ornithologist. It purported to offer a new kind of sociology – one informed by surrealism and working with a ‘mass’ of Observers recording day-to-day interactions. Various commentators have debated the importance and precise identity of M-O in its first phase, especially in light of its combination of social science and surrealism. This article draws on new archival research, in particular into the ‘paperwork’ practices (...) of Charles Madge, arguing that M-O is best understood as an attempt to define a new relationship between the survey subject and information organiser. The latter – as sociologist, planner or artist – was a distinctive interwar persona, central to ‘scientific humanism’. Bathos, as a formal strategy in modernist aesthetics, is introduced as an explanation of the failure of this particular part of the M-O project. Questions of subjectivity and data link M-O to a longer history of heterodox sociological inquiry. This analysis resolves some of the apparent paradoxes that have been prominent in studies of M-O, and draws attention to the unfulfilled promise of a vast archive of social data. (shrink)

According to Bas van Fraassen, scientific realists and anti-realists disagree about whether accepting a scientific theory involves believing that the theory is true. On van Fraassen’s own anti-realist empiricist position, accepting a theory involves believing only that the theory is correct in its claims about observable aspects of the world. However, a number of philosophers have argued that acceptance and belief cannot be distinguished and thus that the debate is either confused or trivially settled in favor of the realist. In (...) addition, another set of philosophers have argued that van Fraassen’s empiricist position appeals to an unmotivated distinction between observable and unobservable aspects of the world. This paper aims to reconstruct a van Fraassen-style empiricism about scientific acceptance that avoids these two objections – reconstructed empiricism. (shrink)

The ArgumentThe Republic of Letters of the late seventeenth and eighteenth centuries teaches us two lessons about style in science. First, the bearer of style—individual, nation, institution, religious group, region, class—depends crucially on historical context. When the organization and values of intellectual life are self-consciously cosmopolitan, and when allegiances to other entities are culturally more compelling than those to the nation-state, distinctivelynationalstyles are far to seek. This was largely the case for the Republic of Letters, that immaterial but nonetheless real (...) realm among the sovereign states of the Enlightenment. Second, that form of objectivity which made science seem so curiously detached from scientists, and therefore so apparently unmarked by style at any level, also has a history. The unremitting emphasis on impartial criticism and evaluation within the Republic of Letters encouraged its citizens to distance themselves first from friends and family, then from compatriots and contemporaries, and finally, in the early nineteenth century, from themselves as well. Although this psychological process of estrangement and ultimately of self-estrangement may seldom have been completely realized, the striving was genuine and constitutes part of the moral history of objectivity.

. The present study applies results and methods of psychobiology to intellectual history. Pascal's syndrome is a depressive neurosis associated with morbid effects of scientific certainty. The syndrome is characterized by self‐mortification and conversion experience that represses distressing certainties. The dynamics of the syndrome are assessed from Blake Pascal's psychosis. The ideation of the syndrome is evaluated by reference to the neurology of altered states of consciousness and the biogenic amine hypothesis of depression and mania. The evaluation yields a description (...) of the relation between psychogenic and biogenic factors in the syndrome's etiology. (shrink)

There is a diffuse sentiment that to anthropomorphize is a mild vice that people tend to do easily and pleasingly, but that an adult well educated person should avoid. In this paper it will be provided an elucidation of ``anthropomorphism'' in the field of common sense knowledge, the issue of animal rights, and about the use of humans as a model in the scientific explanation. It will be argued for a ``constructive anthropomorphism'', i.e., the idea that anthropomorphism is a natural (...) attutude to attribute human psychological features to other individuals, no matter they are actually rational agents, or not. If we know the ``grammar'' of this attutude, we can avoid the risks in overestimating the environmental inputs towards anthropomor­phism and, at the same time, take the heuristic advantages of anthropomor­phism in the use of human mind as a model for both everyday circumstances and scientific enterprise.

Complexity in our universe, Herbert Simon once noted, generally takes a hierarchical, nearly decomposable form. If our purpose as biologists is to "carve Nature at the joints," then the quantitative biologist's pattern questions must embody some tentative claim of where the explanatory joints are—only after meaningful qualifications can notions of variance and covariance make sense. In morphometrics, specimens and variables alike can be "carved at the joints," with a correspondingly great gain in explanatory power in both versions. Simon's advice is (...) that the competent biologist's measurements should lie entirely within a single organismal component or else deal entirely with one of the joints. In either context, our best contemporary rhetorics of explanation in biology may resemble morphometrics in their frank combination of carefully supervised parallel quantifications that, taken together, result in new qualifications, leading in turn to new quantifications, and so on. In short, the relation between qualitative and quantitative in the organismal biological sciences is not an opposition but a complementarity, and the modern biometrical statistics of organismal form may be a particularly apposite praxis for exploring it.

This paper contributes to the ongoing reassessment of the controversy between William Bateson and Karl Pearson by characterising what we call “Batesonian Mendelism” and “Pearsonian biometry” as coherent and competing scientific outlooks. Contrary to the thesis that such a controversy stemmed from diverging theoretical commitments on the nature of heredity and evolution, we argue that Pearson’s and Bateson’s alternative views on those processes ultimately relied on different appraisals of the methodological value of the statistical apparatus developed by Francis Galton. Accordingly, (...) we contend that Bateson’s belief in the primacy of cross-breeding experiments over statistical analysis constituted a minimal methodological unifying condition ensuring the internal coherence of Batesonian Mendelism. Moreover, this same belief implied a view of the study of heredity and evolution as an experimental endeavour and a conception of heredity and evolution as fundamentally discontinuous processes. Similarly, we identify a minimal methodological unifying condition for Pearsonian biometry, which we characterise as the view that experimental methods had to be subordinate to statistical analysis, according to methodological standards set by biometrical research. This other methodological commitment entailed conceiving the study of heredity and evolution as subsumable under biometry and primed Pearson to regard discontinuous hereditary and evolutionary processes as exceptions to a statistical norm. Finally, we conclude that Batesonian Mendelism and Pearsonian biometry represented two potential versions of a single genetics-based evolutionary synthesis since the methodological principles and the phenomena that played a central role in the former were also acknowledged by the latter—albeit as fringe cases—and conversely.

We report the results of a study that investigated the views of researchers working in seven scientific disciplines and in history and philosophy of science in regard to four hypothesized dimensions of scientific realism. Among other things, we found that natural scientists tended to express more strongly realist views than social scientists, that history and philosophy of science scholars tended to express more antirealist views than natural scientists, that van Fraassen’s characterization of scientific realism failed to cluster with more standard (...) characterizations, and that those who endorsed the pessimistic induction were no more or less likely to endorse antirealism.

A difference-making account of causality is proposed that is based on a counterfactual definition, but differs from traditional counterfactual approaches to causation in a number of crucial respects: it introduces a notion of causal irrelevance; it evaluates the truth-value of counterfactual statements in terms of difference-making; it renders causal statements background-dependent. On the basis of the fundamental notions 'causal relevance' and 'causal irrelevance', further causal concepts are defined including causal factors, alternative causes, and importantly inus-conditions. Problems and advantages of the (...) proposed account are discussed. Finally, it is shown how the account can shed new light on three classic problems in epistemology, the problem of induction, the logic of analogy, and the framing of eliminative induction. (shrink)

The notion of ‘causal web’ emerged in the epidemiological literature in the early Sixties and had to wait until the Nineties for a thorough critical appraisal. Famously, Nancy Krieger argued that such a notion isn’t helpful unless we specify what kind of spiders create the webs. This means, according to Krieger, (i) that the role of the spiders is to provide an explanation of the yarns of the web and (ii) that the sought spiders have to be biological and social. (...) This paper contributes to the development of the notion of causal web, elaborating on the two following points: (i) to catch the spiders we need multi-fold evidence—specifically, mechanistic and difference-making—and (ii) for the eco-social to be explanatory, the web has to be mechanistic in a sense to be specified.
