I insightfully discuss the question: what is pseudoscience?

According to Thagard, the behavior of practitioners of a field may also be used for demarcation between science and pseudoscience due to its social dimension in addition to the epistemic one. I defended the tendency of pseudoscientists to commit fallacies, and the number of fallacies they commit can be a secondary tool for demarcation problem and this tool is consistent with Thagardian approach. In this paper, I selected the astrology as the case and I revealed nine types of logical fallacies (...) frequently committed by astrologers while introducing their field and/or defending their claims against the scientific inquiries and refutation efforts. I also argued that recognizing these fallacies may help the audience to demarcate between the scientific and the pseudoscientific arguments. (shrink)

We initially characterize what we’ll call existence problems as problems where there is evidence that a putative entity exists and this evidence is not easily dismissed; however, the evidence is not adequate to justify the claim that the entity exists, and in particular the entity hasn’t been detected. The putative entity is elusive. We then offer a strategy for determining whether an existence problem is philosophical or scientific. According to this strategy (1) existence problems are characterized in terms of causal (...) roles, and (2) these problems are categorized as scientific or philosophical on the basis of the epistemic context of putative realizers. We argue that the first step of the strategy is necessary to avoid begging the question with regard to categorization of existence problems, and the second step categorizes existence problems on the basis of a distinction between two ways in which an entity can be elusive. This distinction between kinds of elusiveness takes as background a standard account of inference to the best explanation. Applying this strategy, we argue that the existence of a multiverse is a scientific problem. (shrink)

David Lewis’s latest theory of causation defines the causal link in terms of the relation of influence between events. It turns out, however, that one event’s influencing another is neither a necessary nor sufficient condition for its being a cause of that event. In the article one particular case of causality without influence is presented and developed. This case not only serves as a counterexample to Lewis’s influence theory, but also threatens earlier counterfactual analyses of causation by admitting a particularly (...) troublesome type of preemption. The conclusion of the article is that Lewis’s influence method of solving the preemption problem fails, and that we need a new and fresh approach to the cases of redundant causation if we want to hold on to the counterfactual analysis of causation.

INTRODUCTORY REMARKS It is my lot, if not my duty, in presenting these opening remarks at our conference, to take the title of our meeting seriously. ...

Inspired by Bas van Fraassen’s Stance Empiricism, Anjan Chakravartty has developed a pluralistic account of what he calls epistemic stances towards scientific ontology. In this paper, I examine whether Chakravartty’s stance pluralism can exclude epistemic stances that licence pseudo-scientific practices like those found in Scientology. I argue that it cannot. Chakravartty’s stance pluralism is therefore prone to a form of debilitating relativism. I consequently argue that we need (1) some ground or constraint in relation to which epistemic stances can be (...) ranked by degrees, and (2) some way to demarcate science from pseudo-science so that we know what epistemic stances are about. Regarding (1), I argue that empirical detectability can serve as the ground in relation to which epistemic stances are ranked by degrees. Regarding (2), I argue for ranking sciences on a continuum according to established institutional criteria, rather than attempting to draw a strict demarcation. (shrink)

Homoeopathy is commonly recognised as pseudoscience. However, there is, to date, no systematic discussion that seeks to establish this view. In this paper, we try to fill this gap. We explain the nature of homoeopathy, discuss the notion of pseudoscience, and provide illustrative examples from the literature indicating why homoeopathy fits the bill. Our argument contains a conceptual and an empirical part. In the conceptual part, we introduce the premise that a doctrine qualifies as a pseudoscience if, firstly, its proponents (...) claim scientific standing for it and, secondly, if they produce bullshit to defend it, such that, unlike science, it cannot be viewed as the most reliable knowledge on its topic. In the empirical part, we provide evidence that homoeopathy fulfils both criteria. The first is quickly established since homoeopaths often explicitly claim scientificity. To establish the second, we dive into the pseudo-academic literature on homoeopathy to provide evidence of bullshit in the arguments of homoeopaths. Specifically, we show that they make bizarre ontological claims incompatible with natural science, illegitimately shift the burden of proof to sceptics, and mischaracterise, cherry-pick, and misreport the evidence. Furthermore, we demonstrate that they reject essential parts of established scientific methodology and use epistemically unfair strategies to immunise their doctrine against recalcitrant evidence.

Critical realism, championed by its proponents as the most promising post-positivist social science paradigm, has gained significant influence in the last few decades. This paper provides a critical evaluation of the critical realism movement in the hope of facilitating more fruitful dialogues between its proponents and rivalling schools of sociologists. Two concerns are raised about contemporary critical realism. First, critical realism is not the only philosophical school against positivism and not necessarily the best. Second, critical realists exaggerate the importance of (...) critical realism to social science and conflate philosophy of science with sociological theories. (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)

For a long time, philosophers of science have expressed little interest in the so-called demarcation project that occupied the pioneers of their field, and most now concur that terms like “pseudoscience” cannot be defined in any meaningful way. However, recent years have witnessed a revival of philosophical interest in demarcation. In this paper, I argue that, though the demarcation problem of old leads to a dead-end, the concept of pseudoscience is not going away anytime soon, and deserves a fresh look. (...) My approach proposes to naturalize and down-size the concept, anchoring it in real-life doctrines and fields of inquiry. First, I argue against the definite article “the” in “the demarcation problem”, distinguishing between territorial and normative demarcation, and between different failures and shortcomings in science apart from pseudoscience. Next, I argue that pseudosciences can be fruitfully regarded as simulacra of science, doctrines that are not epistemically warranted but whose proponents try to create the impression that they are. In this element of imitation or mimicry, I argue, lies the clue to their common identity. Despite the huge variety of doctrines and beliefs gathered under the rubric of “pseudoscience”, and the wide range of defects from which they suffer, pseudosciences all engage in similar strategies to create an impression of epistemic warrant. The indirect, symptomatic approach defended here leads to a general characterization of pseudosciences in all domains of inquiry, and to a useful diagnostic tool. (shrink)

V úvodní části zrekapitulujeme v hrubých obrysech Popperovu teorii demarkace v návaznosti na jeho další teze týkající se kritiky induktivních postupů, úlohy metafyziky ve vědě a falzifikaci. Dílo vídeňského filozofa vyvolalo značné množství reakcí, jejichž spektrum sahalo od dílčích modifikací Popperových myšlenek jeho žáky, přes návrhy nových teorií jím inspirovaných, až po zásadní kritiku. Hlavní směry této kritiky načrtneme (bez nároku na úplnost) v další části statě. Polemizujeme především s jednostranným odmítnutím indukce a pokoušíme se zde rehabilitovat některé induktivní postupy. (...) Následně upozorníme na nedostatky Popperova pojetí falzifikace i na problémy použitelnosti jeho demarkačního kritéria na typických příkladech ze sféry metafyziky a "pseudovědy" (psychoanalýza, astrologie). Závěr věnujeme diskuzi o úloze indukce a dedukce ve vědě, posouzení užitečnosti Popperových teorií ve vztahu k současné vědě. (shrink)

Les partisans de Popper ont fait valoir que la plupart des critiques reposaient sur une incompréhension de ses idées. Ils affirment que Popper ne devrait pas être interprété dans le sens où la falsifiabilité est une condition suffisante pour la délimitation de la science. Après avoir abandonné le concept de falsifiabilité, la question de la méthode de démarcation entre science et pseudoscience a été : choisir la théorie la plus probable à des fins pédagogiques, la théorie la plus corroborée par (...) souci de vérité, ou la théorie la plus informative et explicative pour nous rapprocher le plus de réalité ?

Imre Lakatos a proposé une modification du critère de Popper, qu'il a qualifié de « falsification sophistiquée (méthodologique) ». De ce point de vue, le critère de délimitation ne devrait pas s'appliquer à une hypothèse ou à une théorie isolée, mais plutôt à l'ensemble d'un programme de recherche.

J'ai analysé dans ce texte l'exemplifiant de l'auteur pour le programme de recherche de l'émission de lumière (en physique quantique au début). Un exemple détaillé des concepts est présenté par Lakatos dans la section "Effet de Newton sur les (...) normes scientifiques" du même livre. J'ai également fait souvent référence au livre Preuves et Réfutations, publié par Lakatos en 1976, dans lequel il expose sa vision heuristique par une application directe à l'évolution des mathématiques.

Suporterii lui Popper au susținut că cele mai multe critici se bazează pe o interpretare neînțeleasă a ideilor sale. Ei afirmă că Popper nu ar trebui interpretat în sensul că falsificabilitatea este o condiție suficientă pentru delimitarea științei. Unele pasaje par să sugereze că el o consideră doar o condiție necesară. Alte pasaje ar sugera că, pentru ca o teorie să fie științifică, Popper impune (pe lângă falsificabilitate) și alte teste, și că rezultatele negative ale testelor sunt acceptate.

Malgré les critiques de la théorie de Karl Popper sur la falsifiabilité pour la démarcation entre la science et la non-science, principalement la pseudo-science, ce critère est toujours très utile et parfaitement valide après avoir été perfectionné par Popper et ses disciples. De plus, même dans sa version originale, qualifiée de « dogmatique » par Lakatos, Popper n’a pas affirmé que cette méthode constituait un critère absolu de démarcation : un seul contre-exemple ne suffit pas à falsifier une théorie ; (...) une théorie peut légitimement être sauvée de la falsification en introduisant une hypothèse auxiliaire. Comparé à la théorie des révolutions de Kuhn, de qui lui-même s'est dissocié pour la transformer en une théorie des « micro-révolutions », j'estime que la méthode de démarcation de Popper, ainsi que le développement ultérieur proposé par lui, incluant la corroboration et la vraisemblance, même imparfait, n’est pas seulement valable aujourd’hui, mais c’est la meilleure méthodologie de démarcation. -/- SOMMAIRE: -/- Abstract Introduction 1.

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)

Bilimin ne olduğunun tespit edilmesi ve bilimi sözde bilimlerden ya da bilimsel olmayan alanlardan ayırt edecek ölçütün ne olması gerektiğine yönelik tartışma, bilim felsefesinde sınır çizme sorunu olarak ele alınmaktadır. Bu makalede, öncelikle söz konusu soruna yönelik geleneksel yaklaşımlar incelenmiş ve ardından bu yaklaşımların bilimsel toplulukların doğasına ilişkin özellikleri göz ardı ettiği ortaya konmuştur. Daha önce yapılan çalışmalar bilimi daha çok önermeler, ifadeler ya da salt epistemik bir sistem olarak ele almakta ve bilimsel akıl yürütmenin biçimi ile bilimsel kuramların özelliklerine (...) odaklanmaktadır. Bu tespit çerçevesinde, sunulan çalışmada, bilimsel bir disiplinin asgari olarak iki özellik (yapısal ve kanıta dayalı olması) üzerine kurulması gerektiği vurgulanarak, sınır çizme sorununun çözümüne yönelik önerilen alternatif ölçüt bilimin sosyal yönüne dikkat çekmektedir. Bu bakımdan, makalenin asıl ilgisi, sınır çizme sorununu alternatif bir yolla ele alabilmek amacıyla bilimin ve onun uygulayıcılarının sosyal özelliklerine yönelik tespitleri, sözde bilimin uygulayıcıları ile kıyaslayarak aktarmaktır. Makale, bir disiplinin sözde bilim olarak nitelendirilebilmesi için öncelikle o disiplinin bilimsellik iddiasında bulunması, daha sonra bilimsel topluluk tarafından sürdürülen bir araştırma geleneğine kabul edilmemiş ya da bu araştırma geleneği tarafından terk edilmiş olması gerektiği düşüncesi ile sonuçlandırılmıştır.

Despite the criticism of Karl Popper's falsifiability theory for the demarcation between science and non-science, mainly pseudo-science, this criterion is still very useful, and perfectly valid after it was perfected by Popper and his followers. Moreover, even in his original version, considered by Lakatos as "dogmatic", Popper did not assert that this methodology is an absolute demarcation criterion: a single counter-example is not enough to falsify a theory; a theory can legitimately be saved from falsification by introducing an auxiliary hypothesis. (...) Compared to Kuhn's theory of revolutions, which he himself later dissociated from it transforming it into a theory of "micro-revolutions," I consider that Popper's demarcation methodology, along with the subsequent development proposed by him, including the corroboration and the verisimilitude, though imperfect, is not only valid today, but it is still the best demarcation methodology. For argumentation, I used the main works of Popper dealing with this issue, and his main critics and supporters. After a brief presentation of Karl Popper, and an introduction to the demarcation problem and the falsification methodology, I review the main criticisms and the arguments of his supporters, emphasizing the idea that Popper has never put the sign of equality between falsification and rejection. Finally, I present my own conclusions on this issue.

Thomas Kuhn criticized falsifiability because it characterized "the entire scientific enterprise in terms that apply only to its occasional revolutionary parts," and it cannot be generalized. In Kuhn's view, a delimitation criterion must refer to the functioning of normal science. Kuhn objects to Popper's entire theory and excludes any possibility of rational reconstruction of the development of science. Imre Lakatos said that if a theory is scientific or non-scientific, it can be determined independently of the facts.He proposed a modification of (...) Popper's criterion, which he called "sophisticated (methodological) falsification". DOI: 10.13140/RG.2.2.30572.82568. (shrink)

Astrology, a pseudoscience, is highly popular in Turkey. Astrologers, who are its practitioners, produce discourses in the scientific field at the media and at their own platforms. Furthermore, it is possible to find some instances of astrology related activities in Turkish universities. In this article, demarcation of science from pseudoscience and the pseudoscientific status of astrology were discussed in a first place. Next, threats of astrological discourse within economic, educational and medical fields and their threats to society were expressed with (...) some examples. Instances of the astrological activities within higher education institutions, such as an astrology-based master degree thesis, the astrology certificate programs, and an astrology column in an official medical school magazine were evaluated, and it was put forward that they contributed to increase the level of threat and it was also claimed that the existence of astrological activities in the universities contradicts the main purpose and principles of the higher education. In conclusion, some regulatory actions like the implementation of the scientific literacy and demarcation problem to each level of educational curriculum, a general policy for excluding the pseudoscience from higher education institutions and a recommended health warning at the top of the astrology were suggested.

Many philosophers have come to believe there is no single criterion by which one can distinguish between a science and a pseudoscience. But it need not follow that no distinction can be made: a multifactorial account of what constitutes a pseudoscience remains possible. On this view, knowledge-seeking activities fall on a spectrum, with the clearly scientific at one end and the clearly non-scientific at the other. When proponents claim a clearly non-scientific activity to be scientific, it can be described as (...) a pseudoscience. One feature of a scientific theory is that it forms part of a research tradition being actively pursued by a scientific community. If a theory lacks this form of epistemic warrant, this is a pro tanto reason to regard it as pseudoscientific. (shrink)

A definition of pseudoscience is proposed, according to which a statement is pseudoscientific if and only if it (1) pertains to an issue within the domains of science, (2) is not epistemically warranted, and (3) is part of a doctrine whose major proponents try to create the impression that it is epistemically warranted. This approach has the advantage of separating the definition of pseudoscience from the justification of the claim that science represents the most epistemically warranted statements. The definition is (...) used to explain why proponents of widely divergent criteria for the demarcation between science and pseudoscience tend to be in almost complete agreement on the particular demarcations that should presumably be based on these general criteria.

In recent years, many philosophers of science have rejected the “value-free ideal” for science, arguing that non-epistemic values have a legitimate role to play in scientific inquiry. However, this philosophical position raises the question of how to distinguish between legitimate and illegitimate influences of values in science. In this paper, we argue that those seeking to address this “new” demarcation problem can benefit by drawing lessons from the “old” demarcation problem, in which philosophers tried to find a way of distinguishing (...) between science and non-science. Many of those who worked on this problem ultimately found that efforts to provide necessary and sufficient conditions for defining science failed, and most concluded that the best solution to the problem was to characterize scientific hypotheses, theories, and research programs in terms of some common norms. We suggest that those seeking to distinguish between legitimate and illegitimate value influences on science would do well to adopt a similar approach. Rather than attempting to establish necessary and sufficient conditions for identifying appropriate value influences, it will be more fruitful to evaluate scientific activities based on their adherence to a set of epistemic and ethical norms that can be implemented in scientific practice by means of rules, conventions, policies, and procedures.

Archaeology is currently bound to a series of metaphysical principles, one of which claims that reality is composed of a series of discrete objects. These discrete objects are fundamental metaphysical entities in archaeological science and posthumanist/new Materialist approaches and can be posited, assembled, counted, and consequently included in quantitative models (e.g. Big Data, Bayesian models) or network models (e.g. Actor-Network Theory). The work by Sørensen and Marila shows that archaeological reality is not that discrete, that some objects cannot be easily (...) identified, and that perhaps reality is not always necessarily composed of discrete objects. The aim of this article is to take Sørensen and Marila’s arguments to their ultimate logical consequences: most archaeological theory today operates under the illusion of a general metaphysics. This illusion dictates not only that all of reality is composed of discrete objects, but that since reality manifests in a certain way, there has to be a methodology that accurately represents that reality. A brief discussion on the notion of “conjecture,” as conceived in certain historical theories, is also presented. (shrink)

Finding the demarcation criterion for the identification of scientific knowledge is the most important task of normative epistemology. Pseudoscience is not a harmless leisure activity, it can pose a danger to the functioning of liberal democratic societies and the well-being of their citizens. First, there is an outline of how to define science instrumentally without slipping into the detrimental heritage of conceptual essentialism. The second part is dedicated to Popper’s falsification criterion and the objections of its opponents, which eventually led (...) to the abandonment of “naïve” falsificationism. Then I present two promising solutions to the problem, namely the ostensive definition of pseudoscience and the cognitive research of pseudoscientific thinking. In conclusion, I suggest to further extend the typology of alternatives to science to include parascience. (shrink)

There is a long tradition of preferring local theories to ones that posit lawful or causal influence at a spacetime distance. In this paper, we argue against this preference. We argue that nonlocality is scientifically unobjectionable and that nonlocal theories can be known. Scientists can gather evidence for them and confirm them in much the same way that they do for local theories. We think these observations point to a deeper constraint on scientific theorizing and experimentation: the (quasi‐) isolation of (...) causal or lawful influence. We argue that this requirement ought to replace the locality desideratum in science. We then explore the possibility that the order of explanation has been reversed: perhaps it is isolatable influence that determines what counts as local in the first place. (shrink)

Selon Popper, une théorie scientifique peut être légitimement sauvée de la falsification en introduisant une hypothèse auxiliaire permettant de générer de nouvelles prédictions falsifiables. De plus, s’il existe des soupçons de biais ou d’erreur, les chercheurs pourraient introduire une hypothèse auxiliaire falsifiable, qui permettrait de procéder à des tests. De nombreux autres auteurs ont proposé des critères pour démarquer la science de la pseudoscience. Celles-ci incluent généralement la croyance en l'autorité, des expériences irremplaçables, des exemples choisis, le manque de volonté (...) de tester, le non-respect des informations de réfutation, un subterfuge intégré, des explications abandonnées sans remplacement.

O teorie științifică, conform lui Popper, poate fi salvată în mod legitim de falsificare prin introducerea unei ipoteze auxiliare care să permită generarea de predicții noi, falsificabile. De asemenea, dacă există suspiciuni de părtinire sau eroare, cercetătorii ar putea introduce o ipoteză falsificabilă auxiliară, care să permită testarea. Dar această tehnică nu poate rezolva problema în general, deoarece orice ipoteză auxiliară poate fi contestată în același mod, ad infinitum. Pentru a rezolva această regresiune, Popper introduce ideea unei declarații de bază, (...) o afirmație empirică care poate fi folosită atât pentru a determina dacă o teorie dată este falsificabilă și, dacă este cazul, pentru a corobora ipotezele de falsificare.

Popper's supporters argued that most criticism is based on an incomprehensible interpretation of his ideas. They argue that Popper should not be interpreted as meaning that falsifiability is a sufficient condition for the demarcation of science. Some passages seem to suggest that he considers it is only a necessary condition. Other passages would suggest that for a theory to be scientific, Popper requires (besides falsifiability) other tests, and that negative test results are accepted. A demarcation criterion based on falsifiability that (...) includes these elements will avoid the most obvious counter-arguments of a criterion based on falsifiability alone.

Ethics is of vital importance to the Swedish educational system, as in many other educational systems around the world.Yet, it is unclear how ethics should be dealt with in school, and prior research and evaluations have found serious problems regarding ethics in education.The field of moral education lacks clear and widely accepted definitions of key concepts, and these ambiguities negatively impact both research and educational practice. This thesis draws a distinction between three approaches to ethics in school – the descriptive (...) ethics approach, the value transmission approach, and the inquiry ethics approach – and studies in what way (if at all) they are prescribed by the national curriculum for the Swedish compulsory school, how they relate to students’ moral reasoning about technology choices and online behaviour, and what pedagogical merits and disadvantages they have. Hopefully, this both contributes to reducing the ambiguities of the field, and to answering the question of how ethics should be dealt with in education. The descriptive ethics approach asserts that school should teach students empirical facts about ethics, such as what views and opinions people have. The value transmission approach holds that school should mediate some set of predefined values to the students and make sure the students come to accept these values.The inquiry ethics approach is the view that school should teach students to reason and think critically about ethics and to engage in ethical inquiry. The role of ethics in the curriculum has not been studied in light of the above distinction, in prior research,and such an investigation is undertaken here.The results suggest that ethics has a prominent, but complicated, role in the Swedish national curriculum. Although no explicit distinction is drawn or acknowledged in the curriculum, all three approaches are prescribed throughout the curriculum, albeit to different degrees. In the general section of the curriculum, the value transmission and inquiry ethics approaches are more extensively prescribed than the descriptive ethics approach. It was found that most of the syllabi contained explicit references to ethics, while some only contained implicit references to ethics, and two syllabi lacked references to ethics altogether. In the syllabi, the inquiry ethics approach is the most dominant, both in the sense of being present in the most syllabi, and in the sense of being more strongly prescribed in many of the syllabi where several approaches occur.The value transmission approach has the weakest role in the syllabi. In total, the inquiry ethics approach is the approach most strongly prescribed by the curriculum. But prior research has shown that inquiry ethics is very rarely implemented in the classroom. In this thesis, it is found that the inquiry ethics and the value transmission approaches are incompatible, given certain reasonable interpretations, which makes the finding that inquiry ethics is rarely implemented less surprising, since value transmission is practiced in schools. Some possible causes, and some consequences, of this is discussed. The students, in their moral reasoning about technology choices, reasoned in accordance with several classical normative theories – including consequentialism, deontological ethics and virtue ethics – and in doing so, they expressed reasoning that in the discussion is found to be in conflict with the values of the value foundation in the curriculum. These findings complement earlier findings, for example that students in their actions contradict the value foundation, by adding that such conflicts also exist in their reasoning. The existence of these conflicts is found to be problematic for a value transmission approach. Many of the students defended very restrictive views on disclosing personal information online, and prior research as well as the present data has shown that adults typically hold views that are very similar to these, concerning how they think that young people ought to act online. On the other hand, youths’ actual online behaviour, as reported in earlier studies, differs considerably from this. In line with this, the students also seemed to endorse a form of private morals view, according to which moral choices are simply up to one’s own taste, which would yield an escape exit from the restrictive views mentioned above, and permit any behaviour. In the discussion, it is argued that this is the result of an attempt at value transmission from the grown-up community, probably including teachers, which might seem to work, since the students claim to hold certain views, but which likely instead constitutes a false security, since these values are not actually accepted, but only paid lip service to, and the adults are therefore wrong in their belief that the students are protected by a certain set of values (that they think the students are upholding), since the students in fact do not uphold, and therefore do not act based upon, these values. This situation risks making the students more vulnerable than had no value transmission attempt been taken in the first place. Hence, the attempted value transmission runs the risk of counteracting its purpose of helping the students acquire a safe online behaviour. Throughout the moral reasoning mentioned above, extensive variations in the students’ reasoning were found, both interpersonally and intrapersonally, both in the decision method and in the rightness criterion dimensions, as well as in between the dimensions.The existence of such variations is a novel finding, and while possible applications in future research are discussed, it is also noted that this existence constitutes a reason to question the successfulness of both the value transmission and the inquiry ethics endeavours of the educational system. The results and discussions described above highlight the importance of investigating the merits of the different approaches. Several arguments that arise from the material of this thesis are presented, evaluated and discussed. The ability of each approach to fulfil some alleged key aims of ethics education is scrutinised; their abilities to educate for good citizenship, to educate for quality of life of the individual, and to facilitate better educational results in other subjects are all investigated, as well as the ability of each approach to help counteract the influence from online extremist propaganda aimed at young people and to promote safe online behaviour in general. It is concluded that the inquiry ethics approach has the strongest support from the material of this thesis. Some consequences for school practice are discussed, and it is concluded that changing the role of ethics in the curriculum would be beneficial, downplaying the role of value transmission and further increasing, and making more explicit and clear, the role of inquiry ethics. It is also shown that there are strong reasons for the inclusion of a new subject in the Swedish compulsory education with special focus on ethics. (shrink)

The question of how to distinguish between science and non-science, the so-called ‘demarcation problem’, is one of the most high-profile, perennial, and intractable issues in the philosophy of science. It is not merely a philosophical issue, however, since it has a significant bearing on practical policy questions and practical decisions. This essay develops a pragmatic approach to the demarcation problem: it argues that while there are some core principles that we can use in distinguishing between science and non-science, particular judgments (...) and decisions about something's scientific status depend, in part, on practical goals and concerns.

Problém demarkace mezi vědou a metafyzikou byl v první polovině 20. století považován za centrální problém normativní filozofie vědy. W. W. Bartley ve svém textu z roku 1962 přesvědčivě ukázal, že dichotomie mezi vědou a metafyzikou (ne-vědou) není důležitá, jelikož neposkytuje žádné relevantní údaje o daném tvrzení (teorii). Otázku posunul do roviny hodnocení a akceptability teorií a představil vlastní kritérium "demarkace" mezi dobrou a špatnou teorií podle množství problémů, které řeší. V této studii bude představena Bartleyho argumentace v kontextech popperiánských (...) diskuzí, Bartleyho kritika induktivismu a Popperovy falzifikace. Cílem tohoto textu je zejména kritická reakce na znovuotevření problému demarkace mezi vědou a pseudovědou v současné diskuzi a poukázání na již minimálně trojí (Bartley, Kuhn, Laudan) odmítnutí problému demarkace v minulosti. V závěru studie je nabídnuto řešení v souladu s Bartleyho koncepcí akceptability teorií. (shrink)

Although a substantial literature in anthropology and comparative religion explores divination across diverse societies and back into history, little research has integrated the older ethnographic and historical work with recent insights on human learning, cultural transmission, and cognitive science. Here we present evidence showing that divination practices are often best viewed as an epistemic technology, and we formally model the scenarios under which individuals may overestimate the efficacy of divination that contribute to its cultural omnipresence and historical persistence. We found (...) that strong prior belief, underreporting of negative evidence, and misinferring belief from behavior can all contribute to biased and inaccurate beliefs about the effectiveness of epistemic technologies. We finally suggest how scientific epistemology, as it emerged in Western societies over the past few centuries, has influenced the importance and cultural centrality of divination practices.

The problem of demarcating science from nonscience remains unsolved. This article executes an analytical process of elimination of different demarcation proposals put forward since the professionalization of the philosophy of science, explaining why each of those proposals is unsatisfactory or incomplete. Then, it elaborates on how to execute an alternative multicriterial scientific demarcation project put forward by Mahner. This project allows for the demarcation not only of science from non-science and from pseudoscience, but also of different types of sciences and (...) of scientific fields from each other. This article also offers arguments in favor of accepting two types of scientific demarcations, namely epistemic-warrant scientific demarcations and territorial scientific demarcations, and argues in favor of accepting a territorially broad scientific demarcation.

Methodological naturalists generally believe that science is the best and only method for discovering the properties of reality and what exists. A central tenet of methodological naturalism is that science is limited to evaluating only natural things. Science cannot allow for the possibility of supernatural objects because doing so would irreparably damage the scientific method. Or, it may be that evaluating the supernatural is beyond the capabilities of science. In this thesis, I challenge these assumptions. I defend a form of (...) naturalism known as Provisory Methodological Naturalism which holds that science can, at least theoretically, evaluate supernatural claims. Provisory methodological naturalists believe the notion that science only evaluates natural things is provisional and subject to being overruled. Should supernatural objects exist, science would be able to observe them. (shrink)

Moral intuitionism, once an apparently moribund metaethical position, has seen a resurgence of interest of late. Robert Audi, a leading moral intuitionist, has argued that in order for a moral belief to qualify as intuitional, it must fulfill four criteria: it must be non-inferential, firmly held, comprehended, and pre-theoretical. This paper centers on the fourth and seemingly most problematic criterion: pre-theoreticality. The paper begins by stipulating the defensibility of the moral cognitivism upon which moral intuitionism turns. Next, the paper develops (...) the distinction between semantic and epistemic pre-theoreticality, and goes on to explore and reject the putative ubiquity of the theoreticality of first-order moral discourse: it argues that on a defensible understanding of theoryhood, both semantic and epistemic pre-theoretical moral belief is not only possible, but in fact frequently realized. The paper then briefly explores and rebuts objections to (epistemic) pre-theoreticality issuing from (i) the “Cornell Realists” and (ii) considerations of the epistemic relevance of the epistemic/valuational background of moral belief. The paper concludes that, so far as the pre-theoreticality criterion is concerned, moral intuitionism remains in the running as a viable thesis regarding foundationally justified first-order moral belief and knowledge.

One of the most important characteristics of modern science is its replicability and objectivity. This means that a scientific result is taken as such only when it has been reproduced by other scientists. Indeed, the replicability of a scientific result in an objective and independent way by members of a scientific community is the cornerstone of science. Experimental laser physics is an example of “normal” science, where it is no doubt that the phenomenon could be replicated; however, the replication process (...) may not be straightforward since it requires a good understanding of the physics behind it, as well as good technical skills. In this article, two laboratory cases of experiments on laser physics are presented: the first one deals with a Nitrogen N2 laser with a Polloni excitation circuit, and the second one deals with a transversally excited TEA carbon dioxide laser. For the nitrogen laser, it will be shown that reproducibility failed, and therefore, the reported experiment cannot be taken as a valid contribution to the advancement and understanding of nitrogen laser physics and technology. On the other hand, for the case of the TEA carbon dioxide laser, several comments are presented on the development of this finally successful experiment. Both cases show the importance of being technically up-dated in order to reproduce or improve the results reported by other researchers. Finally, a discussion about: What can we learn about the research practice from these two cases? It is presented, as well as the conclusions about the case studies; we hope they may be useful to philosophers of science and young scientists alike. (shrink)

The conception of René Descartes as the arch-rationalist has been sufficiently exploded in recent literature; however, there is still a large lacuna in our understanding of how empirical research and experimentation fits within his philosophy. My dissertation is directed at addressing just this problem. I contend that Descartes’ famed method is not a singular monolith but instead two interdependent methods: one directed at metaphysical and epistemological truth, while the other directed at empirical questions and contingent facts of the world. I (...) claim there is evidence for this position not only in his actual scientific practice, but also in the rhetorical structure of the Discourse on Method and the Principles of Philosophy. In exploring the empirical side of Descartes’ method, I show how his unusual system produces a system of experiment designed to serve both as a discovery and verification tool at the same time. As a further application of my interpretation, I argue that the Passions of the Soul and Descartes’ ethical theory expressed in his correspondence must also be seen as part of his two-fold methodology. Instead of attempting to cast Descartes as a virtue ethicist or deontologist, as is normally done, I emphasize that Descartes’ ethics is centered on the mind-body union, and therefore, includes an empirical element as well. The end result is an ethics that requires a detailed study of mechanics, anatomy, physics, as well as medicine. Lastly, I show how this methodology can help us understand the works of some of his early followers: Claude Gadroys and Jacques Rohault. Both of these philosophers not only serve to ground my interpretation, but also to highlight aspects of Cartesian that have often been passed over. I show how the experimentalism of Jacques Rohault goes beyond the epistemological boundaries set up by Descartes, as signifies a new direction that will ultimately eclipse the Cartesian school of thought. In the case of Claude Gadroys, I present a concrete example of the exploitation of the over generality of Cartesian principles. In so doing, I show that while Descartes’ experimentalism was intended to rule out the possibility of occult causes, he in fact created a system that allowed for them, only under a different guise.
