Demarcation of Science

It is mostly agreed that Popper's criterion of falsifiability fails to provide a useful demarcation between science and pseudo-science, because ad-hoc assumptions are always able to save any theory that conflicts with the empirical data, and a characterization of ad-hoc assumptions is lacking. Moreover, adding some testable predictions is not very difficult. It should be emphasized that the Duhem-Quine argument does not simply make the demarcation approximate, but it makes it totally useless. Indeed, no philosophical criterion of demarcation is presently (...) able to rule out even some of the most blatant cases of pseudo-science, not even approximatively. This is in sharp contrast with our firm belief that some theories are clearly not scientific. Where does this belief come from? In this paper I argue that it is necessary and possible to recognize the notion of syntactic simplicity that is able to tell the difference between empirically equivalent scientific and non-scientific theories, with a precision that is adequate to many important practical purposes, and it fully agrees with the judgments generally held in the scientific community.

What is science, and what is it not? Is falsifiability the key to drawing this line? How and why does science work? Should we worry whether science is talking about a "real" world? And should we stop thinking there is a single thing we can call "the scientific method"? With Deborah Mayo, Robert Rynasiewicz, and Drew Arrowood.

What differentiates scientific research from non-scientific inquiry? Philosophers addressing this question have typically been inspired by the exalted social place and intellectual achievements of science. They have hence tended to point to some epistemic virtue or methodological feature of science that sets it apart. Our discussion on the other hand is motivated by the case of commercial research, which we argue is distinct from (and often epistemically inferior to) academic research. We consider a deflationary view in which science refers to (...) whatever is regarded as epistemically successful, but find that this does not leave room for the important notion of scientific error and fails to capture distinctive social elements of science. This leads us to the view that a demarcation criterion should be a widely upheld social norm without immediate epistemic connotations. Our tentative answer is the communist norm, which calls on scientists to share their work widely for public scrutiny and evaluation. (shrink)

Este resumo é um trabalho baseado no artigo publicado por Ferreira (2021), intitulado "Será a psicanálise uma pseudociência? Reavaliando a doutrina utilizando uma lista de multicritérios". Além de se apoiar nele, coloca uma proposta de expansão sobre as implicações éticas de sua conclusão. O artigo original, publicado na revista Debates em Psiquiatria, busca fazer uma avaliação da doutrina psicanalítica utilizando da proposta de demarcação de Sven Ove Hansson.

This paper reviews how research on the demarcation problem has developed, starting from Popper’s criterion of falsifiability and ending with recent naturalistically oriented approaches. The main differences between traditional and contemporary approaches to the problem are explicated in terms of six postulates called the traditional assumptions. It is argued that all of the assumptions can be dismissed without giving up on the demarcation problem and that doing so might benefit further discussions on pseudoscience. Four present-day research movements on evaluating the (...) boundaries of science are introduced: (1) philosophy of pseudoscience, (2) social epistemology of dissent, (3) agnotology, and (4) evaluation of expertise. Researchers working within these areas have abandoned some or all traditional assumptions. (shrink)

Bilim felsefesinin temel tartışma konuları arasında yer alan bilimde rasyonalite ve sınır çizme problemleri, bilimin ne olduğundan hareketle, bilime bir alan belirleme, bilim olan ile olmayan arasına bir sınır çizme, söz konusu sınırı ve bilimi belirli bir rasyonalite düşüncesiyle temellendirme talepleri doğrultusunda şekillenen, birbiriyle bağlantılı iki problemdir. Bilimde rasyonalite ve sınır çizme problemleri, özellikle 20. yüzyıldan itibaren, mantıkçı pozitivizmle birlikte, temel bir konu olarak gündeme gelmektedir. Mantıkçı pozitivistler, bilimin sınırlarını belirlemek, bu doğrultuda bilim olmayanı bilimden elemek üzerinde durmaktadır. Metafiziğin bilimden (...) elenmesi, bilimsel metot, bilimsel açıklama söz konusu anlayışın temel tartışma konularını oluşturmaktadır. Mantıkçı pozitivistler bilimsel ölçüt olarak doğrulanabilirlik ilkesini ve bu ilkeye eşlik eden mantıksal çözümleme yöntemini öne sürmektedir. (shrink)

Solving the “new demarcation problem” requires a distinction between epistemically legitimate and illegitimate roles for non-epistemic values in science. This paper addresses one ‘half’ (i.e. a sub-problem) of the new demarcation problem articulated by the Gretchenfrage: What makes the role of a non-epistemic value in science epistemically illegitimate? I will argue for the Explaining Epistemic Errors (EEE) account, according to which the epistemically illegitimate role of a non-epistemic value is defined via an explanatory claim: the fact that an epistemic agent (...) is motivated by a non-epistemic value explains why the epistemic agent commits a particular epistemic error. The EEE account is inspired by Douglas’ and Steel’s “functionalist” or “epistemic constraint” accounts of epistemic illegitimacy. I will suggest that the EEE account is able to meet two challenges that these two accounts face, while preserving the key intuition underlying both accounts. If my arguments succeed, then the EEE account provides a solution to one half of the new demarcation problem (by providing a definition of what makes the role of a non-epistemic value epistemically illegitimate) and it opens up new ways for addressing the other half (i.e. characterizing an epistemically legitimate role of non-epistemic values).

Toplumların gelişmesi, kendisini oluşturan bireylerin bilimsel düşünmelerine ve yaşamlarında bilimsel bilgileri kullanmalarına bağlıdır. Bilimsel düşünerek yaşamını devam ettiren bireylerin yaşamlarında hata yapma olasılıkları daha düşüktür. Çünkü bilgi, öğrenmeler, araştırmalar ve gözlemler sonucu elde edilen doğrulara ve ilkelere dayanır. Bilimsel bilgi ise geçerli ve kabul edilebilir metotlar kullanarak yapılan araştırmalar sonucu gözlemler yoluyla elde edilen bilgilerdir. Bilimsel bilgiler doğruluğu ve geçerliği defalarca kanıtlanmış kanunlaşmış bilgilerdir.

Fen eğitimi ve öğretiminin anahtar unsurlarından bir tanesi bilimin doğasının ve özelliklerinin doğru bir şekilde tespit edilmesidir. Bilimin doğasına yönelik tespitler fen eğitimi yöntemlerini birçok açıdan etkilemektedir. Fen eğitimi ve fen öğretimi ile ilgili olan kişiler bilimin doğasının açık bir şekilde öğretilmesi gerektiğini kabul etmektedir. Thomas Kuhn’un bilim tarihi, bilim felsefesi ve bilim sosyolojisi alanlarını içeren incelemeleri neticesinde ileri sürdüğü bilimin yapısına, işleyişine ve doğasına yönelik tezleri (paradigma, olağan bilim, bilimsel devrimler, eşölçülemezlik, bulmaca çözme, kuram seçimi, keşif ve gerekçelendirme ayrımı) (...) fen eğitimi ve öğretimi alanında sıklıkla başvurulan kaynaklar olmuştur. Bu doğrultuda makalede mantıkçı pozitivist bilim anlayışının bilimin nesnel, evrensel, kesin gerçekleri ortaya çıkaran, sosyal-kültürel değerlerden ve ön yargılardan bağımsız, bilimsel bilginin birikimsel bir şekilde ilerlediği yönündeki iddiası bilimin gerçek doğasını yansıtamadığı düşüncesiyle Kuhn’un görüşleri çerçevesinde tartışılmaktadır. Makalenin temel savı Kuhn’un bilime ve bilimin doğasına yönelik tespitlerinin bilimin gelişen, dönüşen ve değişen yapıdaki gerçek doğasına vurgu yaptığı ve böylece fen eğitiminde sıklıkla başvurulan bilimin doğasına yönelik kavrayışı dönüştürdüğüdür.

In this paper, I describe some strategies for teaching an introductory philosophy of science course to Science, Technology, Engineering, and Mathematics (STEM) students, with reference to my own experience teaching a philosophy of science course in the Fall of 2020. The most important strategy that I advocate is what I call the “Second Philosophy” approach, according to which instructors ought to emphasize that the problems that concern philosophers of science are not manufactured and imposed by philosophers from the outside, but (...) rather are ones that arise internally, during the practice of science itself. To justify this approach, I appeal to considerations from both educational research and the epistemology of testimony. In addition, I defend some distinctive learning goals that philosophy of science instructors ought to adopt when teaching STEM students, which include rectifying empirically well-documented shortcomings in students’ conceptions of the “scientific method” and the “nature of science.” Although my primary focus will be on teaching philosophy of science to STEM students, much of what I propose can be applied to non-philosophy majors generally. Ultimately, as I argue, a successful philosophy of science course for non-philosophy majors must be one that advances a student’s science education. The strategies that I describe and defend here are aimed at precisely that end. (shrink)

Muitos psicólogos ainda pensam que a maior referência para falar sobre a demarcação de ciência/pseudociência é Popper. Entretanto, as discussões sobre o problema da demarcação não se encerraram com o critério da falseabilidade, e a filosofia teve diversos avanços. Este trabalho tem por objetivo atualizar os estudantes e profissionais de psicologia sobre os avanços no campo da filosofia da ciência, com um enfoque na teoria de Hansson. Para isso, foi consultado o livro “Philosophy of Pseudoscience: Reconsidering the Demarcation Problem”, obra (...) que marcou o começo da reviravolta sobre o alegado fim do problema da demarcação, bem como os ensaios de Hansson disponíveis na literatura. Foi possível observar que, após Popper, Laudan foi outro filósofo que teve um importante impacto no debate. Ele tentou decretar o fim da discussão, tratando a demarcação como um pseudoproblema, e afirmando que todas as tentativas de demarcar ciência/pseudociência anteriores haviam fracassado, incluindo a de Popper. Por muito tempo seu decreto vigorou, até que novas teorias foram desenvolvidas e filósofos da ciência começaram um movimento para contrapô-lo. Uma das teorias contemporâneas é a de Hansson, que propõe uma definição ampliada de ciência, não se resumindo às ciências empíricas. Para ele, ciência é a prática que nos fornece as afirmações mais confiáveis que podem ser feitas, em um determinado momento, sobre um objeto de estudos abarcado por uma comunidade de disciplinas de conhecimento. Já a pseudociência, para Hansson, é uma doutrina desviante que se afasta consideravelmente dos critérios de qualidade científicos, enquanto seus maiores proponentes tentam criar a impressão de que ela representa o que há de mais confiável sobre seu objeto de estudos. A proposta de Hansson também apresenta uma lista de multicritérios, que auxiliam a identificar se uma determinada doutrina é pseudocientífica. Ela inclui os seguintes itens: 1) Credo na autoridade, 2) Experimentos não repetíveis, 3) Exemplos escolhidos a dedo, 4) Resistência à testagem, 5) Desdém com informações refutantes, 6) Construída em subterfúgio, e 7) Explicações são abandonadas sem substituição. Ao discutir as propostas contemporâneas para o problema da demarcação, psicólogos e analistas do comportamento terão melhores recursos para diferenciar ciência da pseudociência. (shrink)

Introduction: In the past, psychoanalysis was classified as a pseudoscience. Karl Popper was one of those who objected to the idea that psychoanalysis is a science, using falsifiability. However, falsifiability cannot be considered sufficient anymore, since it carries major weaknesses and better alternatives to address the issue are available. Objective: This article intends to evaluate the scientific status of psychoanalysis concerning the demarcation problem. Method: In order to do so, Sven Ove Hansson’s criteria were used. His proposal consists of a (...) set of sufficient and necessary conditions which is complemented by a multicriteria list that helps identifying pseudosciences. It was analyzed how much psychoanalysis fits each of Hansson's seven items, besides proposing the addition of an eighth. Results: The results showed that psychoanalysis was compatible with all eight demarcation of pseudoscience’s items. Conclusion: In the end, the conclusion was that even if falsifiability was to be dismissed, the evidence suggests that there are still enough reasons to affirm that psychoanalysis is a pseudoscience, since it significantly deviates from scientific quality standards.

Introdução: A psicanálise já foi classificada como pseudociência no passado. Karl Popper foi um daqueles que traçou objeções à doutrina psicanalítica, usando do critério da falseabilidade. Entretanto, a falseabilidade não pode mais ser considerada suficiente para resolver o problema, já que implica em dificuldades consideráveis, e melhores alternativas para abordar a questão estão disponíveis. Objetivo: Este artigo tem por objetivo avaliar o status científico da psicanálise em relação ao problema da demarcação. Método: Para fazer isso, o critério de Sven Ove (...) Hansson foi utilizado: este consiste em um conjunto de condições suficientes e necessárias, que é complementado com uma lista de multicritérios que auxiliam a identificar pseudociências. Foi analisado o quanto a psicanálise se encaixava em cada um dos sete itens da lista de Hansson, além de ser proposta a adição de um oitavo item. Resultados: Os resultados mostraram que a psicanálise era compatível com todos os oito itens da lista de demarcação de pseudociências. Conclusão: Ao final, a conclusão foi de que mesmo que a falseabilidade deva ser descartada, as evidências sugerem que ainda temos motivos suficientes para afirmar que a psicanálise é uma pseudociência, já que ela se distancia significativamente dos padrões de qualidade científicos.

Sözde-bilim ile ilgili bu tartışmalar uluslararası literatürde yapılıyor olsa da Türkiye’de henüz bu konuların eleştirel olarak ele alındığı söylenemez. Dolayısıyla sözde-bilimlerin eleştirel olarak ele alındığı öğrenme ortamlarının öğrencilerin bilime ve sözde-bilime ilişkin algılarına etkisi üzerine yapılacak araştırmalar konunun daha iyi anlaşılmasını sağlayabilir ve belki de ilerideki program değişiklerinde öğretim programlarında sözde-bilimin yer bulmasının yolunu açabilir.

Research on the folk psychology of free will suggests that people believe free will is incompatible with determinism and that human decision-making cannot be exhaustively characterized by physical processes. Some suggest that certain elements of Western cultural history, especially Christianity, have helped to entrench these beliefs in the folk conceptual economy. Thus, on the basis of this explanation, one should expect to find three things: a significant correlation between belief in dualism and belief in free will, that people with predominantly (...) incompatibilist commitments are likely to exhibit stronger dualist beliefs than people with predominantly compatibilist commitments, and people who self-identify as Christians are more likely to be dualists and incompatibilists than people who do not self-identify as Christians. We present the results of two studies that challenge two of these expectations. While we do find a significant correlation between belief in dualism and belief in free will, we found no significant difference in dualist tendencies between compatibilists and incompatibilists. Moreover, we found that self-identifying as Christian did not significantly predict preference for a particular metaphysical conception of free will. This calls into question assumptions about the relationship between beliefs about free will, dualism, and Christianity. (shrink)

Bilim ve çarpık bilim arasına sınır çizebilmek için yapılan girişimler farklı teorilerin gelistirilmesini sağlamıştır. Henüz net bir sınır çizilememiştir ve tartışmalar devam etmektedir. İlk olarak doğrulama ve yanlışlama teorileri daha sonraları ise bilim çalışmalarını bir bütün olarak ele alan, araştırma programları olarak gören teoriler sunulmuştur. Bilimsel çalışmaların, yeni sorunlar üretmesi ve eleştirel bakış açısına sahip olması da bilim olanın sınırlarını çizebilmek için ölçütler arasında sayılmıştır. Bu çabalar ile bilim pratiklerinin irdelenmesi zamanla bilim insanına ve bilim kurumlarına yönelmiştir. Bu konunun önemli (...) bir sorunu bilim yolu ile ulaşabileceğimiz doğru bilginin ne olduğu ile neyin bilim olarak ele alınabileceğinin tek bir sorun gibi ele alınmasıdır. Bilimsel doğrunun ne olduğu ile bilimsel bilginin ne olduğu tartışması iç içe yürütülmektedir. Bir diğer sorun ise bilimin sınırlarını belirlerken bilim çalışmaları dışında etik ve sosyal ölçütler aranmasıdır. Bu yaklaşımlar konuyu çözümsüz bir noktaya götürmektedir. Diğer önemli nokta Astroloji örneğinin yanlış bilgilerle ele alınmasıdır. Bu çalışmada tartışmanın bilim pratiklerinde kalması gerektiği savunulmuştur. Çarpık bilimi ayırmak için sık kullanılan Astroloji örneği yeniden ele alınarak yanlış yargılara sebep olan bilgiler düzeltilmeye çalışılmıştır. Ayrıca önermelerin bilimsel doğruyu ayırma konusundaki önemi ve durumu tartışılmış böylece neyin bilim, neyin bilimsel doğru ve neyin bilim dışı olduğu netleştirilmeye çalışılmıştır. (shrink)

No hace mucho tiempo, la demarcación, el cambio teórico o la racionalidad científica coloreaban la paleta de la filosofía de la ciencia. Hoy estos problemas son vistos como asuntos clásicos de la disciplina. En La actitud científica, Lee McIntyre renueva el escaparate filosófico recuperando el problema de la demarcación, defendiendo que lo distintivo de la ciencia es “que se preocupa por la evidencia y está dispuesta a modificar sus teorías en función de la evidencia”. Se presentan a continuación una síntesis (...) de la obra y cinco objeciones. Not long ago, demarcation, theory change and scientific rationality used to clutter up debates on the philosophy of science. These issues are now seen as the classical subjects of the discipline. In The Scientific Attitude, Lee McIntyre revamps the philosophical showcase by taking over the demarcation problem by asserting that “what is distinctive about science is that it cares about evidence and is willing to change its theories on the basis of evidence”. I hereby synthetize his proposal and offer five objections. (shrink)

While science is taken to differ from non-scientific activities in virtue of its methodology, metaphysics is usually defined in terms of its subject matter. However, many traditional questions of metaphysics are addressed in a variety of ways by science, making it difficult to demarcate metaphysics from science solely in terms of their subject matter. Are the methodologies of science and metaphysics sufficiently distinct to act as criteria of demarcation between the two? In this chapter we focus on several important overlaps (...) in the methodologies used within science and metaphysics in order to argue that focusing solely on methodology is insufficient to offer a sharp demarcation between metaphysics and science, and consider the consequences of this for the wider relationship between science and metaphysics.

In his review of Charles Spearman’s The Nature of ‘Intelligence’, R. G. Collingwood launched an attack upon psychometrics that was expanded in his Essay on Metaphysics. Although underrated by friend and foe alike, Collingwood’s critique identified a number of defects in the thinking of psychometricians that subsequently became entrenched. However, his main complaint was that psychology generally was a ‘fashionable scientific fraud’. This charge was inspired by his more general views on logic and metaphysics, which, however, as I argue, are (...) logically unsustainable. Ironically, other elements of his philosophy – his ‘fallacy of calculation’ and concept of ‘scale of forms’ – are relevant to psychometrics and tip the scales in favour of his otherwise unwarranted charge.

Since Popper and Lakatos, the demarcation line between science and non-science has been considered one of the fundamental issues of the philosophy of science. According to Lakatos, pseudoscience is a non-science, which appears as science, using science's public authority. Since then, mountains of texts have been published on how non-sciences, such as astrology, are not sciences. -/- But the enemy is not on the other side of the border. The enemy is in our midst.

In this article, I seek to improve upon a definition of pseudoscience put forward by Sven Ove Hansson. I argue that not only does its use of ‘pseudoscientific statement’ as definiendum inadequately address the theoretical issue of demarcation, it also makes the definition inapt for practical demarcation. Moreover, I argue that Hanson’s definition subsumes statements and associated practices that are forms of bad science, resulting in an unfavourably wide concept. I try to save the definition from the brunt of this (...) critique by arguing that some pseudoscientific statements are particularly significant when demarcating a discipline as a pseudoscience.

The aim of this study is to determine the perceptions of gifted and talented 4th grade primary school students towards pseudoscience, as well as their awareness of scientific process skills by using pseudoscientific scenarios. Specifically, the aim is to reveal the students’ knowledge about crystals, which is a pseudoscientific issue, views on treatments carried out with crystals, experiences about experiments, knowledge about scientific process skills and scientific process skills used in proposing research methodology for claims about crystals’ healing abilities.

The demarcation between science and non-science seems to play an important role in the process of scientific change, as theories regularly transition from being considered scientific to being considered unscientific and vice versa. However, theoretical scientonomy is yet to shed light on this process. The goal of this paper is to tackle the problem of demarcation from the scientonomic perspective. Specifically, we introduce scientificity as a distinct epistemic stance that an agent can take towards a theory. We contend that changes (...) in this stance are to be traced and explained by scientonomy. Thus, we formulate a new law of theory demarcation to account for changes in scientificity within the scientonomic framework. (shrink)

The general character of science and the methodology it employs are in specific terms referred to as observation and experimentation. These two methodologies reflect how science differs from other systematic modes of inquiries. This description characterises, strictly, ‘Western science’ and it is contrasted with the indigenous mode of enquiry that has come under the name, ‘African science’. In contemporary scholarship, ‘African science’ is being condemned to the level of the mysticoreligious or supernaturalist worldview. ‘African science’ is said to be purely (...) esoteric, personal, and devoid of elements of objectivity and rigorous theorization. In this paper, I re-examine this recondite issue by further reflecting and strengthening some of the ideas put forward by some African scholars to affirm that there is a distinct method of ‘African science’ that can be termed scientific. In defending a pluralist thesis toward knowledge, scientific inclusive, this paper posits that there exist varieties of inquiry beyond what has been developed in the ‘West’ which can still be justifiably termed scientific. In addition to pluralism, it argues further that the social character of science, which makes it a part of social and cultural traditions, qualifiedly justifies ‘African science’ as a true science. I will employ the newly formulated conversational method endorsed by the Conversational School of Philosophy in this inquiry. Keywords : African science, mystico-religious, rigorous, pluralism, Western science. (shrink)

Hempel, Popper, and Kuhn argue that to be scientific is to be testable, to be falsifiable, and most nearly to do normal science, respectively. I argue that to be scientific is largely to be interactive, offering some examples from science to show that the ideas from different fields of science interact with one another. The results of the interactions are that hypotheses become more plausible, new phenomena are explained and predicted, we understand phenomena from a new perspective, and our worldview (...) becomes simpler. I also argue that given that the interactions are impressive features of science, astrology and religion would be regarded as science, provided that there are similar interactions in those enterprises.

Throughout the debate on psi, skeptics have almost universally insisted on different standards for evaluating the evidence, claiming that psi represents a radical departure from our current scientific understanding. Thus, there is considerable ambiguity about what standard of evaluation psi must meet. Little attention has been paid to the possible harm to the integrity of scientific investigation from this resulting inconsistency in testing standards. Some have proposed using a Bayesian framework as an improvement on this dilemma in order to more (...) explicitly model beliefs, assumptions, and background scientific knowledge, especially when evaluating a controversial hypothesis. Recently, Kuhn’s notion of paradigms, which constrains scientific research within bound- aries believed to be most productive, has been incorporated into a Bayesian framework. Within this framework, I explore a likely paradigm or meta-theory used by skeptics that typically constrains research and makes it difficult for psi evidence to be accepted. It appears that such a paradigm would in many respects have difficulty accounting for consciousness, which is fundamental to an understanding of psi. I discuss why psi data are likely to play a key role in making progress in solving the problem of consciousness. Thus, applying different standards of evaluation to psi data is likely counterproductive. (shrink)

ArgumentThe subject of the paper is the shift from an astrology-oriented astronomy towards an allegedly more objective, mathematically grounded approach to astronomy. This shift is illustrated through a close reading of Tycho Brahe's scientific development and the contemporaneous changes in his communicational strategies. Basing the argument on a substantial array of original sources it is claimed that the Danish astronomer developed a new astronomical discourse in pursuit of credibility, giving priority to observational astronomy and natural philosophical questions. The abandonment of (...) astrology in public discourse is primarily explained by Tycho's social position and greater sensibility to controversial issues. Tycho's example suggests that the changes in rhetorical strategies regarding astrology should be given more recognition in the history of astronomy. (shrink)

What sets the practice of rigorously tested, sound science apart from pseudoscience? In this volume, the contributors seek to answer this question, known to philosophers of science as “the demarcation problem.” This issue has a long history in philosophy, stretching as far back as the early twentieth century and the work of Karl Popper. But by the late 1980s, scholars in the field began to treat the demarcation problem as impossible to solve and futile to ponder. However, the essays that (...) Massimo Pigliucci and Maarten Boudry have assembled in this volume make a rousing case for the unequivocal importance of reflecting on the separation between pseudoscience and sound science.

. This article traces the intellectual history of scientific studies of intercessory prayer published in English between 1965 and the present by focusing on the conflict and discussion they prompted in the medical literature. I analyze these debates with attention to how researchers articulate the possibilities and limits medical science has for studying intercessory prayer over time. I delineate three groups of researchers and commentators: those who think intercessory prayer can and should be studied scientifically, those who are more skeptical (...) and articulate the limits of science around this topic, and those who focus primarily on the pragmatic applications of this knowledge. I analyze these contests as examples of what Thomas Gieryn calls “epistemic authority” as medical researchers engage in what he describes as “boundary‐work” or “the discursive attribution of selected qualities to scientists, scientific methods, and scientific claims for the purposes of drawing a rhetorical boundary between science and some less authoritative residual non‐science.” ).

Susan Haack has recently attempted to discredit religion by showing that science is an extended and enhanced version of common sense while religion is not. I argue that Haack’s account is misguided not because science is not an extended version of common sense, as she says. It is misguided because she assumes a very restricted, and thus inadequate, account of common sense. After reviewing several more realistic models of common sense, I conclude that common sense is rich enough to allow (...) various kinds of extensions. Just as science can be correctly seen as an enhanced version of common sense, so also religion. (shrink)

One of the reasons the history of parapsychology and its ancestor psychical research is intriguing is because it addresses a central issue: the boundaries of science. This article provides an overview of the historiography of parapsychology and presents an approach to investigate the Dutch history of parapsychology contributing to the understanding of this central theme. In the first section the historical accounts provided by psychical researchers and parapsychologists themselves are discussed; next those studies of sociologists and historians understanding parapsychology as (...) deviant and even potentially revolutionary are dealt with; third, more contemporary studies are examined whereby enterprises such as parapsychology are understood as central to the culture in which they arose. On the basis of this analysis a new direction in the historiography of the subject is suggested in the fourth section, centred upon the relation between parapsychology and psychology in the Netherlands throughout the 20th century. In the Netherlands not only were pioneering psychologists such as Gerard Heymans actively involved in experiments into telepathy, the first professor in parapsychology in the world – Wilhelm Tenhaeff – was appointed in 1953 at Utrecht University and in the 1970s and 1980s parapsychology had its own research laboratory at Utrecht University in the division of psychology. This unique situation in the Netherlands deserves scholarly attention and makes an interesting case to investigate the much-neglected connections between the fields of psychology and parapsychology in the 20th century. The connections between psychology and parapsychology might help us to understand why parapsychology came to be regarded as a pseudoscience. (shrink)

The present article deals with a kind of parapsychology called metapsychics (metapsíquica) as conceived and practised in Spain between 1923 and 1925. First we focus on the reception of a treatise by Richet that evoked both support (Ferrán) and criticism (Mira). Then we examine some experiments on clairvoyance performed at the Marquis of Santa Cara’s home, dealing chiefly with the rise and fall of a case of prodigious vision. The analysis gives special attention to the question of how metapsychics was (...) understood and to which discussions it gave rise. The authors argue that the project of metapsychics must be understood within a frame of two tendencies, namely, the increasing popularization and the demarcation of science that were under way in modern society.

Largely unacknowledged by historians of the human sciences, late-19th-century psychical researchers were actively involved in the making of fledgling academic psychology. Moreover, with few exceptions historians have failed to discuss the wider implications of the fact that the founder of academic psychology in America, William James, considered himself a psychical researcher and sought to integrate the scientific study of mediumship, telepathy and other controversial topics into the nascent discipline. Analysing the celebrated exposure of the medium Eusapia Palladino by German-born Harvard (...) psychologist Hugo Münsterberg as a representative example, this article discusses strategies employed by psychologists in the United States to expel psychical research from the agenda of scientific psychology. It is argued that the traditional historiography of psychical research, dominated by accounts deeply averse to its very subject matter, has been part of an ongoing form of ‘boundary-work’ to bolster the scientific status of psychology.

This paper is a polemic with Wojciech Sady’s forgoing paper. The main objection to his new approach to demarcation problem is that this approach does not accomplish the criterion formulated in it . Sady accuses medical ethics of not being scientific but forgets that he does it from the philosophical point of view. The only reasonable way to solve the demarcation problem is to define its practical aim — what do we need it for? One of such possible aims is (...) to automate the process of distribution of scientific grants. Key words KNOWLEDGE, SCIENCE, CRITERION. (shrink)

Laudan’s argument against the possibility of a demarcation criterion for scientific theories rests on establishing that any criterion must be a necessary and sufficient condition. But Laudan’s argument at most establishes that any criterion must provide a necessary condition and a possibly different sufficient condition. His own claims suggest that such a criterion is possible.

In the 2005 Kitzmiller v Dover Area School Board case, a federal district court ruled that Intelligent Design creationism was not science, but a disguised religious view and that teaching it in public schools is unconstitutional. But creationists contend that it is illegitimate to distinguish science and religion, citing philosophers Quinn and especially Laudan, who had criticized a similar ruling in the 1981 McLean v. Arkansas creation-science case on the grounds that no necessary and sufficient demarcation criterion was possible and (...) that demarcation was a dead pseudo-problem. This article discusses problems with those conclusions and their application to the quite different reasoning between these two cases. Laudan focused too narrowly on the problem of demarcation as Popper defined it. Distinguishing science from religion was and remains an important conceptual issue with significant practical import, and philosophers who say there is no difference have lost touch with reality in a profound and perverse way. The Kitzmiller case did not rely on a strict demarcation criterion, but appealed only to a “ballpark” demarcation that identifies methodological naturalism (MN) as a “ground rule” of science. MN is shown to be a distinguishing feature of science both in explicit statements from scientific organizations and in actual practice. There is good reason to think that MN is shared as a tacit assumption among philosophers who emphasize other demarcation criteria and even by Laudan himself. (shrink)

In a recent article, Thomas Nagel argues against the court’s decision to strike down the Dover school district’s requirement that biology teachers in Dover public schools inform their students about Intelligent Design. Nagel contends that this ruling relies on questionable demarcation between science and nonscience and consequently misapplies the Establishment Clause of the constitution. Instead, he argues in favor of making room for an open discussion of these issues rather than an outright prohibition against Intelligent Design. We contend that Nagel’s (...) arguments do not succeed. First, we argue that Nagel’s case trades on an ambiguity regarding the content of non-theological views and fails to engage adequately some of the problems of ID. Then we raise concerns about Nagel’s conclusion; specifically, we will point to three incongruities between Nagel’s argument and his conclusion, and then we will raise a more general worry about the likely impact of Nagel’s view.

In recent controversies about Intelligent Design Creationism (IDC), the principle of methodological naturalism (MN) has played an important role. In this paper, an often neglected distinction is made between two different conceptions of MN, each with its respective rationale and with a different view on the proper role of MN in science. According to one popular conception, MN is a self-imposed or intrinsic limitation of science, which means that science is simply not equipped to deal with claims of the supernatural (...) (Intrinsic MN or IMN). Alternatively, we will defend MN as a provisory and empirically grounded attitude of scientists, which is justified in virtue of the consistent success of naturalistic explanations and the lack of success of supernatural explanations in the history of science (Provisory MN or PMN). Science does have a bearing on supernatural hypotheses, and its verdict is uniformly negative. We will discuss five arguments that have been proposed in support of IMN: the argument from the definition of science, the argument from lawful regularity, the science stopper argument, the argument from procedural necessity, and the testability argument. We conclude that IMN, because of its philosophical flaws, proves to be an ill-advised strategy to counter the claims of IDC. Evolutionary scientists are on firmer ground if they discard supernatural explanations on purely evidential grounds, instead of ruling them out by philosophical fiat. (shrink)
