Radical constructivism has had a major influence on present-day education, especially in the teaching of science and mathematics. The article provides an epistemological profile of constructivism and considers its strengths and weaknesses from the standpoint of its educational implications. It is argued that there are two central problems with constructivism: anti- realism and individualism which, in turn, lead to difficulties associated with idealism and relativism which, together, prove fatal for the theory.

This paper is an introduction to the special issue commemorating the 50th anniversary of the publication of _The Structure of Scientific Revolutions_ by Thomas Kuhn. It introduces some main ideas of _Structure_, as its change in historical perspective for the interpretation of scientific progress, the role and nature of scientific communities, the incommensurability concept, or the new-world problem, and summarizes some philosophical reactions. After this introduction, the special issue includes papers by Alexander Bird, Paul Hoyningen-Huene and George Reisch on different (...) aspects of Kuhn’s work. (shrink)

The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has always been the rule. This article aims to investigate the similarities and differences between Kuhn and French philosophy of science or ‘French epistemology’. The first part will argue that he is influenced by French epistemologists, but by lesser known authors (...) than often thought. The second part focuses on the reactions of French epistemologists on Kuhn’s work, which were often very critical. It is argued that behind some superficial similarities there are deep disagreements between Kuhn and French epistemology. This is finally shown by a brief comparison with the reaction of more recent French philosophers of science, who distance themselves from French epistemology and are more positive about Kuhn. Based on these diverse appreciations of Kuhn, a typology of the different positions within the philosophy of science is suggested. (shrink)

Beginning by offering a conceptual analysis of change – a statement of what change of any kind is – the paper sets out to examine possible ways of understanding a very common and important variety of change that may be called ‘evolutionary’. These changes include anything from the production of a clay pot on a potter's wheel to the emergence of a system of management, or from the effects of an analgesic drug to the development of a new programme of (...) care. As few philosophers have discussed such topics, theories are borrowed from the philosophy of science that attempt to explain the development and rationality of science. The ideas of Karl Popper and Thomas Kuhn are discussed and criticized, before turning to evolutionary theories: Darwinian and Lamarckian. The paper ends by offering a model that, it is hoped, may help in thinking about a wide range of changes. (shrink)

A growing interest in and concern about the adequacy and fairness of modern peer-review practices in publication and funding are apparent across a wide range of scientific disciplines. Although questions about reliability, accountability, reviewer bias, and competence have been raised, there has been very little direct research on these variables.The present investigation was an attempt to study the peer-review process directly, in the natural setting of actual journal referee evaluations of submitted manuscripts. As test materials we selected 12 already published (...) research articles by investigators from prestigious and highly productive American psychology departments, one article from each of 12 highly regarded and widely read American psychology journals with high rejection rates (80%) and nonblind refereeing practices.With fictitious names and institutions substituted for the original ones (e.g., Tri-Valley Center for Human Potential), the altered manuscripts were formally resubmitted to the journals that had originally refereed and published them 18 to 32 months earlier. Of the sample of 38 editors and reviewers, only three (8%) detected the resubmissions. This result allowed nine of the 12 articles to continue through the review process to receive an actual evaluation: eight of the nine were rejected. Sixteen of the 18 referees (89%) recommended against publication and the editors concurred. The grounds for rejection were in many cases described as “serious methodological flaws.” A number of possible interpretations of these data are reviewed and evaluated. (shrink)

De una u otra forma, los diferentes procesos independentistas iberoamericanos de comienzos del siglo XIX suelen ser involucrados dentro de la larga cadena revolucionaria que alternativamente sacudió a ambos meridianos del mundo occidental a lo largo de no menos de cincuenta años (1774-1824), para otros ciento treinta y seis (1668-1824)3, o incluso ciento sesenta años (1645-1824). Consumado el mencionado ciclo revolucionario americano, este significó o bien la transformación —Canadá, Brasil, Cuba y Puerto Rico— o bien el derrocamiento del "Antiguo régimen (...) colonial" en la casi totalidad del continente americanos, y con ello surgimiento de un nuevo y ampliado orden político y económico mundial.

It is noted that Popper separates the creation of concepts, conjectures, hypotheses and theories—the context of invention—from the testing thereof—the context of justification—arguing that only the latter is susceptible of rigorous logical analysis. Efforts on the part of others to shift or eradicate the demarcation established by this distinction are discussed and the relationship of these considerations to the claims of “strong artificial intelligence” is pointed out. It is argued that the mode of education of scientists, as well as reports (...) of celebrated scientists, support Popper's judgement in this matter. An historical episode from Faraday's later career is used to illustrate the historiographical strength of Lakatos' “methodology of research programs.”. (shrink)

Recent years have seen growing evidence of a fruitful engagement between phenomenology and cognitive science. This paper confronts an in-principle problem that stands in the way of this intellectual coalition, namely the fact that a tension exists between the transcendentalism that characterizes phenomenology and the naturalism that accompanies cognitive science. After articulating the general shape of this tension, I respond as follows. First, I argue that, if we view things through a kind of neo-McDowellian lens, we can open up a (...) conceptual space in which phenomenology and cognitive science may exert productive constraints on each other. Second, I describe some examples of phenomenological cognitive science that illustrate such constraints in action. Third, I use the mutually constraining relationship at work here as the platform from which to bring to light a domesticated version of the transcendental and a minimal form of naturalism that are compatible with each other.

In his late years, Thomas Kuhn became interested in the process of scientific specialization, which does not seem to possess the destructive element that is characteristic of scientific revolutions. It therefore makes sense to investigate whether and how Kuhn’s insights about specialization are consistent with, and actually fit, his model of scientific progress through revolutions. In this paper, I argue that the transition toward a new specialty corresponds to a revolutionary change for the group of scientists involved in such a (...) transition. I will clarify the role of the scientific community in revolutionary changes and characterize the incommensurability across specialties as possessing both semantic and methodological aspects. The discussion of the discovery of the structure of DNA will serve both as an illustration of my main argument and as reply to one criticism raised against Kuhn—namely, that his model cannot capture cases of revolutionary yet non-disruptive episodes of scientific progress. Revisiting Kuhn’s ideas on specialization will shed new light on some often overlooked features of scientific change. (shrink)

On a cultural level, and for Christian theology as part of a long tradition in the evolution of religion, evolutionary epistemology “sets the stage,” as it were, for understanding the deep evolutionary impact of our ancestral history on the evolution of culture, and eventually on the evolution of disciplinary and interdisciplinary reflection. In the process of the evolution of human knowledge, our interpreted experiences and expectations of the world (and of the ultimate questions we humans typically pose to the world) (...) have a central role to play. What evolutionary epistemology also shows us is that we humans can indeed take on cognitive goals and ideals that cannot be explained or justified in terms of survival‐promotion or reproductive advantage only. Therefore, once the capacities for rational knowledge, moral sensibility, aesthetic appreciation of beauty, and the propensity for religious belief have emerged in our biological history, they cannot be explained only in biological/evolutionary terms. Finally, in this way a door is opened for seeing problem solving as a central activity of our research traditions. As philosophers of science have argued, one of the most important shared rational resources between even widely divergent disciplines is problem solving as the most central and defining activity of all research traditions. As will become clear, the very diverse reasoning strategies of theology and the sciences clearly overlap in their shared quests for intelligible problem solving, including problem solving on an empirical, experiential, and conceptual level.

This paper argues that ceteris paribus (cp) laws exist based on a Lewisian best system analysis of lawhood (BSA). Furthermore, it shows that a BSA faces a second trivialization problem besides the one identified by Lewis. The first point concerns an argument against cp laws by Earman and Roberts. The second point aims to help making some assumptions of the BSA explicit. To address the second trivialization problem, a restriction in terms of natural logical constants is proposed that allows one (...) to describe regularities, as specified by basic generics (e.g. ‘birds can fly’) and universals (e.g. ‘all birds can fly’). It is argued that cp laws rather than strict laws might be a part of the the best system of such a regularity-based BSA, since sets of cp laws can be both (a) simpler and (b) stronger when reconstructed as generic non-material conditionals. Yet, if sets of cp laws might be a part of the best system of a BSA and thus qualify as proper laws of nature, it seems reasonable to conclude that at least some cp laws qualify as proper laws of nature.

In this article, we address why our management of the economy, community and business has led to global warming and we discuss the importance of worldviews, ontology, epistemology and axiology in the search for alternative paths of development. We do this by focusing on the concept of Circular Economy. Circular Economy is often presented as a solution to the problems of a globalized economy in the form of over-exploitation of resources, climate change and pollution of the environment. Within the mainstream (...) economics paradigm, the aim is how to increase the effectiveness of resource extraction and utilization in order to maintain growth. We contrast this with the paradigm of Ecological Economics where the goal of the economy is to achieve and secure a higher quality of life. Circular Economy often side steps the deep ontological and epistemological questions we need to answer if we are to address the complex and interrelated environmental, economic and social problems we face today. This can be a limiting factor in the search for creative and long-term solutions. However, within the Circular Economy discourse, we find strands that critically engage with the foundations of mainstream Economics and so, innovative solutions for the society of the future are a possibility. We argue that to bring about a lasting solution to the interconnected social, economic and environmental problems, Circular Economy must engage with the ontological, epistemological and axiological foundations of mainstream economics. To further this argument, we apply Imre Lakatos’ ‘research program’ model to philosophy of science as our framework of analysis and draw lessons for business and communities. (shrink)

To many atheists the existence of evil seems to provide a conclusive argument against the existence of God. God is by definition omnipotent and perfectly good; a perfectly good being will remove evil in so far as he can, an omnipotent being can remove any evil he chooses, so if there is a God there will be no evil, but there is evil, hence there is no God. Theists normally challenge this argument by challenging the premiss that a perfectly good (...) being will remove evil in so far as he can. The theistic defence is usually put as the defence that many evils are logically necessary conditions of greater goods, and hence a perfectly good being may allow them to occur in order to bring about the greater good; so a perfectly good being may well allow some evils to occur.

If there is a single discipline of science calling the basic concepts of biology into question, it is without doubt microbiology. Indeed, developments in microbiology have recently forced us to rethink such fundamental concepts as the organism, individual, and genome. In this paper I show how microorganisms are changing our understanding of natural aggregations and develop the concept of a Darwinian population to embrace these discoveries. I start by showing that it is hard to set the boundaries of a Darwinian (...) population, and I suggest thinking of a Darwinian population as a relative property of a Darwinian individual. Then I argue, in contrast to the commonly held view, that Darwinian populations are multispecies units, and that in order to accept the multispecies account of Darwinian populations we have to separate fitness from natural selection. Finally, I show how all these ideas provide a theoretical framework leading to a more precise understanding of the ecology of endosymbiosis than is afforded by poetic metaphors such as ‘slavery’.

L’article propose une analyse comparative des positions de Popper et de Kuhn sur quatre points liés : la comparaison des « cadres théoriques » ou des « paradigmes scientifiques » ; le pouvoir contraignant que sont susceptibles d’avoir les arguments invoqués dans les discussions critiques ; les éléments qui, en fin de compte, pèsent ou doivent peser sur les praticiens lorsqu’il s’agit d’élire un cadre théorique au détriment d’un autre ; et enfin, la conception qu’ont chacun des deux auteurs de (...) ce que Kuhn a nommé la « science normale ». On commence par discuter en détails les comptes-rendus dans lesquels Popper explique pourquoi les choix scientifiques de Galilée et de Kepler sont conformes à la méthodologie falsificationniste. On montre de là, premièrement, qu’à suivre à la lettre ces comptes-rendus, il faut conclure que les données expérimentales non problématiques — les énoncés de base unanimement acceptés — ne suffisent pas à elles seules à imposer en droit la falsification empirique (puisque sur la base des mêmes mesures de Tycho Brahé, Kepler a eu raison d’admettre que l’hypothèse des orbites circulaires était empiriquement réfutée, tandis que Galilée a eu raison d’admettre le contraire). On montre alors, deuxièmement, qu’au-delà des différences importantes entre Popper et Kuhn au niveau des lexiques et de l’idéal de scientificité, la méthodologie poppérienne, bien qu’elle se revendique « logique », ne donne concrètement pas plus que la conception kuhnienne pourtant si souvent stigmatisée comme « sociologique », lorsqu’il s’agit d’indiquer ce qu’un bon scientifique devrait faire, que ce soit en période « révolutionnaire » ou en période de « science normale ».

Some astronomers believe that we have discovered that Pluto is not a planet. I contest this assessment. Recent discoveries of trans-Neptunian Pluto-sized objects do not require that we exclude Pluto from the planets. But the obvious alternative, that classificatory revision is a matter of arbitrary choice, is also unpalatable. I argue that this classificatory controversy — which I compare to the controversy about the classification of the platypus — illustrates how our classificatory practices are laden with normative commitments of a (...) distinctive kind. I argue that the “norm-ladenness” of classification has philosophically significant ramifications for how we think about scientific disputes and debates in the metaphysics of classification such as the monism/pluralism debate.

Although postmodernist thought has become prominent in some educational circles, its influence on science education has until recently been rather minor. This paper examines the proposal of Michalinos Zembylas, published earlier in this journal, that Lyotardian postmodernism should be applied to science educational reform in order to achieve the much sought after positive transformation. As a preliminary to this examination several critical points are raised about Lyotard's philosophy of education and philosophy of science which serve to challenge and undermine Zembylas’ (...) project. Subsequently, the three main theses of Lyotard that Zembylas considers beneficial and wishes to transpose onto science classrooms and pedagogy are scrutinized and found to be more of a hindrance than a help to curriculum reformers.

This paper challenges Bird’s view that scientific progress should be understood in terms of knowledge, by arguing that unjustified scientific beliefs (and/or changes in belief) may nevertheless be progressive. It also argues that false beliefs may promote progress.

Van Fraassen has recently argued that empiricism can be construed as a stance, involving commitments, attitudes, values, and goals, in addition to beliefs and opinions. But this characterisation emerges from his recognition that to be an empiricist can not be to believe, or decide to commit to belief in, a foundational proposition, without removing any basis for a non-dogmatic empiricist critique of other philosophical approaches, such as materialism. However, noticeable by its absence in Van Fraassen's discussions is any mention of (...) Bartley's ‘pancritical rationalism’, for Bartley offers a cohesive argument that genuine dogmatism lies precisely in the act of commitment to an idea. The consequence of denying this, he thinks, is an opening of the floodgates to irrationalism: if to rely on reasoned argument in decision-making is fundamentally an act of faith, then there is a tu quoque – “I simply have a different faith” – that may be employed by those who wish to shield their views from criticism. This raises the following question: why should it be any less dogmatic to adopt particular commitments, attitudes, values, and goals, rather than a particular belief or opinion, come what may? And if Bartley is right that there is only one non-dogmatic attitude – the critical attitude – then why might this not be adopted by an empiricist, a materialist, a metaphysician, or anyone else?
