4E pedagogy is being promoted in the target article by Videla, Veloz, and Pino. In my commentary, the nature of teaching and whether or not 4E cognition is radical constructivist are discussed.

Open peer commentary on the article “I Can’t Yet and Growth Mindset” by Fiona Murphy & Hugh Gash.: What Murphy and Gash are attempting to do is to solve a significant problem some students have being successful in school, one that is not often addressed in any significant way. The language used to describe the lessons has some significant departures from radical constructivism. It is, no doubt, beneficial that the students in the study may have developed improvements in self-image, but, (...) as seen in other work, the application of radical constructivism to develop and extend the work started in the study could result in more and more lasting improvements.

Open peer commentary on the article “Constructing Constructivism” by Hugh Gash. Upshot: Gash describes some very interesting and exemplary work using RC-influenced research and practices. I worry that his third stage of a three-stage emergence of constructivist epistemology in the study of cognitive development is consistent with a distinction between focus on individual cognitive development and focus on knowledge not in the mind but in the group, inconsistent with RC. An alternative is given and the issue of an RC perspective (...) on social justice is discussed. (shrink)

In this discussion note, I examine scattered comments about evil from John Dewey’s works. After a brief consideration of what critics like Reinhold Niebuhr have said about the weaknesses of Dewey’s theodicy, I will offer my own critique. In short, I argue that Dewey subverts his own theory of inquiry when he comes to the problem of the origin and genesis of evil.

Open peer commentary on the target article “Arguments Opposing the Radicalism of Radical Constructivism” by Gernot Saalmann. Excerpt: Gernot Saalmann uses the term “radical” in the sense of something “extreme.” For example, in §1, he contrasts “radical” constructivists with “moderate” constructivists. This adjectival usage of the word “radical” as “extreme” is a slang usage from the American sub-culture called “Surfers” which originated in the late 1950s or early 1960s. “Radical,” in their slang means: “At or exceeding limits of control or (...) safety…” (Oxford English Dictionary OED 2007) .

Open peer commentary on the target article “Who Conceives of Society?” by Ernst von Glasersfeld. Excerpt: What follows is offered as an alternative explanation of the nature and status of the concept of society. This alternative is entirely compatible with radical constructivism as described elsewhere by von Glasersfeld and some others. This is not a claim of the truth-value of this alternative interpretation, but instead is no more and no less than a claim that there is an alternative explanation that (...) fits and is useful. It is not even a claim of primacy or superiority in some comparative sense. It is merely the claim that this alternative explanation of the nature and status of the concept of society exists, is viable, and is compatible with radical constructivism: a radical constructivist’s explanation of “society.”.

Purpose: This contribution to the Festschrift honoring Ernst von Glasersfeld gives some insight into the perpetual problem of understanding radical constructivism (RC). Parallels with the Middle Way school of Buddhism appear to shed light on this challenge. Conclusion: The hegemony realism has over the thinking of even the most highly educated in our civilization plays a major role in their failure to understand RC. Those still subject to realism in their thinking interpret statements by those in RC in ways incompatible (...) with RC. Until realists disequilibrate over mismatches between realist expectations and experiences, no alternative way of thinking is accessible to them and misinterpretations of RC will continue. Practical implications: While we cannot change someone else's understanding, in our interactions with them we can focus on creating situations in which those who do not understand us might disequilibrate. If we are successful, they are likely to begin to escape the domination of realism in their thinking. Original value: This insight may enable eventual success in our assisting others to understand RC. (shrink)

This book traces the historical lineages of Alvin Plantinga’s religious epistemology from Plato through Augustine and Calvin. It focuses upon this epistemology as a philosophical interpretation of what is generally taken to be a narrow theological doctrine. The author provides a textually based and closely reasoned introduction to the epistemological ideas of Plato, Augustine, Calvin, Plantinga, and several other writers and shows the continuity of a certain approach to the knowledge of God; it may be called the Platonic—Augustinian—Reformed approach.

Recent research has shown that a phase transformation of diamond to a different form of carbon is involved when diamonds are polished in the traditional fashion. The question as to how this phase transformation is activated and maintained to produce high wear rates is of great technological interest since it may radically change the way we view the processing of diamond. This paper describes the use of Raman spectroscopy to examine debris produced on the diamond polishing wheel, both during its (...) preparation and during polishing. In addition, polished diamond surfaces were examined for the possible existence of non-diamond surface layers in an attempt to identify material removal mechanisms. Raman spectroscopy proves ideal for these analyses because its relatively high spatial resolution is well suited to the analysis of small wear features and debris particles, and because of the wealth of information it reveals about chemical structure. This level of structural information has been lacking in previous analyses of diamond polishing debris. In addition to the non-diamond carbon found in the wear debris, significant quantities of two iron oxides, magnetite (Fe3O4) and haematite (α-Fe2O3), were also found. An interesting observation was that a transformation from magnetite to haematite could be induced either by using high power laser excitation or by frictional heating during polishing. It is suggested that some of the Raman peaks previously attributed to lonsdaleite might better be explained by the presence of these oxides. (shrink)

Purpose: Often radical constructivists are confronted with arguments why radical constructivism is wrong. The present work presents a radical constructivist alternative to such arguments: a comparison of the results of two instructional practices, the standard, realist-based instruction and a radical constructivist-based instruction, both in physics courses. Design: Evidence from many studies of student conceptions in standard instruction (Duit 2004) is taken into account. In addition, diagnostic data, pre and post instruction, were collected from over 1,000 students in multiple institutions across (...) the U. S. over a period of about 15 years via an established diagnostic of conceptual understanding of motion and force. Findings: Evidence from many studies of student conceptions in standard instruction (Duit, 2004) is that little or no change in student conceptions happens in standard instruction. About half the students in the particular study reported, all science and engineering majors, experienced standard, realist-based instruction and show an average effect size of 0.6 standard deviations and an average normalized gain of 15%. The other half of the students, none of whom were science and engineering majors, experienced radical constructivist-based instruction and show an average effect size over 2.5 standard deviations and an average normalized gain over 60%. Diagnostic pre scores were nearly the same for both groups. Practical implications: The outcome, that students, neither science nor engineering majors, made changes in understanding foundational topics in physics far greater than science and engineering students, poses (1) an ethical challenge to the continued adherence to standard, realist-based instructional practices and (2) an intellectual challenge to the usefulness and appropriateness of the elitist-realist paradigm on which such standard instruction is based. Conclusion: This radical constructivist argument uses the effect of paradigms to judge their pragmatic value, not their truth-value. Based on pragmatic value, radical constructivism results in superior outcomes when applied to physics instruction. The approach to instruction can be applied generally in education. (shrink)

Context: In spite of its advantages and its ability to make valid responses to objections, radical constructivism is not mainstream. Problem: Extolling the virtues of radical constructivism and responding logically to the objections does not work. We know this from the evidence of many attempts. Our theoretical stance, radical constructivism, also suggests this approach is not likely to have much influence on realists. We cannot transmit understanding in the signals with which we attempt to communicate. How can we in radical (...) constructivism enable those outside of RC to understand our explanation of human knowing? Method: Examine our understanding of radical constructivism itself, because it is an explanation of how, why and under what circumstances people change their understandings of their experiential worlds. Results: We must find ways to direct the attention of others to situations that they cannot explain with their existing understanding of the world. Then we must create conditions conducive to their revising and testing new understandings for fit with the evidence of their experience. Implications: Since radical constructivism is a theory of human knowing, it tells us how humans develop knowledge, hence it is an answer to the questions central to this special issue. This answer is not one to be used to win in debates with realists. Radical constructivism gives us an answer to the problem of engaging realists in understanding our position, but strategies consistent with radical constructivism are not easily carried out. Developing and executing such strategies is the work at hand. (shrink)

Problem: What alternative strategies from our experiences using a Piaget-based radical constructivist pedagogy might have more and better results than the current practice of responding in debate form, each side trying to prove the other wrong? Method: Use of Slezak’s paper to illuminate the point that the central problem with the interpretation of RC generally used in such writing is that the authors seem not to be able to operate from the central tenet of RC, which is the opposite of (...) that used in realism. Description of how this failure to use the central tenet of RC results in claims that RC is irrelevant to education and to definitions of good teaching. Results: A specific approach shown to be useful in facilitating the construction of new understanding in science is adapted in order to guide interaction between an RC and a realist, which can result in the realist understanding the RC point of view. Implications: Instead of debating with critics of RC, where each side is trying to prove the other side wrong, we need to change the interaction to one in which members of opposing sides attempt to understand the other’s position. In this situation we are in a position to use a pedagogical strategy in which the realist examines her own fundamental assumption that we can know a mind-independent world, and considers the implications of a starting assumption that is exactly the opposite.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

PURPOSE:To report the localization of a gene causing drusen and macular degeneration in a previously undescribed North American family. METHODS:Genetic mapping studies were performed using linkage analysis in a single family with drusen and atrophic macular degeneration. RESULTS:The clinical manifestations in this family ranged from fine macular drusen in asymptomatic middle-aged individuals to atrophic macular lesions in two children and two elderly patients. We mapped the gene to chromosome 6q14 between markers D6S2258 and D6S1644. CONCLUSIONS:In a family with autosomal dominant (...) drusen and atrophic macular degeneration, the gene maps to a 3.2-cM region on chromosome 6q14. This locus appears to be distinct from, but adjacent to, the loci for cone-rod dystrophy 7 (CORD7) and North Carolina macular dystrophy (MCDR1). Future identification of the gene responsible for the disease in this family will provide a better understanding of macular degeneration. (shrink)

The esteemed psychologist and thinker John Dewey headed for previously unexplored philosophical territory with this influential work. Written shortly after World War I, it embodies Dewey's system of pragmatic humanism and maintains that individuals can attain "a more ordered and intelligent happiness" by reconsidering the ultimate effects of their deepest beliefs and feelings. With its promise of achieving an understanding of the past and attaining a brighter future, Reconstruction in Philosophy remains ever relevant.

I explain why, from the perspective of knowledge-centric anti-luck epistemology, objective act consequentialist theories of ethics imply skepticism about the moral status of our prospective actions and also tend to be self-defeating, undermining the justification of consequentialist theories themselves. For according to knowledge-centric anti-luck epistemology there are modal anti-luck demands on both knowledge and justification, and it turns out that our beliefs about the moral status of our prospective actions are almost never able to satisfy these demands if objective act (...) consequentialism is true. This kind of applied moral skepticism introduces problematic limits on our ability to use objective act consequentialism’s explanatory power as evidence for its truth. This is, in part, a product of higher-order defeat as I explain in the final section. There is, however, a silver lining for objective act consequentialists. For there is at least one type of objective act consequentialism, prior existence consequentialism, that is poised to avoid at least some of the epistemic problems discussed in this paper. (shrink)

"A modern classic. Dewey's lectures have lost none of their vigor...The historical approach, which underlay the central argument, is beautifully exemplified in his treatments of the origin of philosophy."-- Philosophy and Phenomenological Research "It was with this book that Dewey fully launched his campaign for experimental philosophy."-- The New Republic Written by an eminent philosopher shortly after the shattering effects of World War I, this volume offers an insightful introduction to the concept of pragmatic humanism. Dewey presents (...) persuasive arguments against traditional philosophical constructs, suggesting their basis in self-justification. He proposes, instead, an examination of core values in terms of their ultimate effects on the self and others. This experimental philosophy was received with both outrage and acclaim for daring to mingle ethics and science. Delivered in 1919 as a series of lectures, Dewey's landmark work appears here in an enlarged edition that features an informative introduction by the author, written more than 25 years after the book's initial publication.

Consider the claim that false beliefs can be justified (JFB). According to Williamson (forthcoming), the most promising argument for JFB is something like this: (1) if p is what one disposed to know or to believe truly would believe, then believing p is justified; (2) sometimes, one disposed to know or to believe truly would believe p even though p is false; so, JFB. But there are counterexamples to (1). I argue that this isn't the most promising argument for JFB. (...) Instead, the thought is that beliefs which manifest a disposition to know or to believe truly are justified. (1) should be replaced by: (1*) if believing p manifests a disposition to know or to believe truly then believing p is justified. (1*) is immune to the counterexamples. (shrink)

This essay is a defense of the social construction of racialism. I follow a standard definition of “racialism” which is the belief that “there are heritable characteristics, possessed by members of our species, that allow us to divide them into a small set of races, in such a way that all the members of these races share certain traits and tendencies with each other that they do not share with other members of any other race”. In particular I want to (...) defend the “radical” social-constructive thesis that holds “the concept of race is exclusively the product of historical and cultural causes. It claims that humans do not tend to classify people into races when groups with different phenotypes meet, save for particular historical circumstances”. The quoted position is the consensus view among historians, sociologists, anthropologists, and other social scientists who study racialism but has recently been criticized by philosophical defenders of cognitive/evolutionary psychological approaches to racialism. Drawing on developmental studies as well as historical and contemporary cross-cultural research, CEP philosophers point to similarities of racialism across time and space. They hold that social constructionist approaches to racialism cannot explain these similarities. I hold that SC approaches do explain these similarities and that such similarities actually pose a significant challenge to the proposed CEP research program on racialism. (shrink)

The philosophical implication that guides the issue addressed here is the following: how does the principle of the common constitute a frontal apophasis to the principle of property in contemporary democracies? I do not pretend to offer an exhaustive answer to this problem. However, I use the argumentative strategy of dividing this paper into three sections: (i) theoretically investigate the dialectical tension between the principle of the common and the principle of property; (ii) analytically observe the premise that the behavioral (...) practices of exacerbated individualism contribute as an act of aversion to the principle of the common and (iii) dwell on the articulation of the notion of the principle of the common as a factor that is present on the threshold between the philosophical vulgar and philosophical universal. Finally, I form some considerations that problematize the naturalized notion of the principle of property in current democracies, in view of the constituent power that the principle of the common holds in the perspective of achieving the well-being of human agents in contemporary community life.

One legacy of post-Enlightenment dualism in the universe of academic discourse is the presence of two approached to notions of duality championed by two differing camps. One camp might arbitrarily be called debunkers; the other might be labeled rationalists. The strategies of the camps are conditioned by traditional notions of inside and outside. Debunkers consider themselves outsiders, beyond a deceptive show filled with tricky mirrors. Rationalists, by contrast, spend a great deal of time among mirrors, listening to explanations from the (...) overseers, attempting to absorb sideshow language, hoping to provide acceptable analytical accounts. If debunkers are intent on discovering generative and, presumably, hidden ideological inscriptions of a given discourse—its situation on what Amiri Baraka calls the “real side” of economic exchange and world exploitative power—rationalists are concerned to study discursive products, to decode or explain them according to forms and formulas that claim to avoid general views or judgments of ideology. Differentiating the camps also is what might be called a thermal gradient: the heat of the debunker’s passion is palpable. It is unnecessary to command him, in the manner of the invisible man’s tormentor, to “Get hot, boy! Get hot!” Rationalists, by contrast, do not radiate. They appear to have nothing personal at stake and remain coolly instructive and intelligently unflappable in their analyses.This tale of an Enlightenment legacy, as I have told it, contrasts a debunking body and rationalist soul. As I have suggested in my opening sentence, however, what is at issue is not so much two actual and substantially distinctive camps as two metonyms for dual approaches to a common subject—namely, notions of duality. My claim is that the Enlightenment reflexivity of academic discourse, devoted to, say, “the Other” and conceived in dualistic terms of self-and-other, expresses itself as an opposition. Thos whom I have called debunkers gladly accept the Other’s sovereignty as a bodily and aboriginal donnée; rationalists work to discover the dynamics of “othering” engaged in by a self-indulgent Western soul. The difficulty of producing usefully analytical or political results for either camp is occasioned by their joint situation within a post-Enlightenment field. Houston A. Baker, Jr. is the Albert M.

In this paper I examine the merits of a “division of moral labor” regulatory system for dual-use research. I borrow an argument from Thomas Douglas against scientific isolationism to show that researchers must be morally responsible for resolving at least some dual-use problems. I then argue that there are key benefits of scientific isolationism that are preserved in a position I call scientific minimalism. I then demonstrate that scientific minimalism, in a division of moral labor system, succeeds in maximizing both (...) scientific freedom and moral efficiency, which I hold to be an essential aim for any proposed alternative regulatory model.

The basing demand on doxastic justification is a widely held and highly intuitive dogma of contemporary epistemology. In Silva [2015, AJP], I argued that the dialectical significance of this dogma is severely limited by our lack of independent grounds for endorsing it. Oliveira [2015, AJP] sought to defend the basing demand on doxastic justification. Here I explain why Oliveira’s attempted defense of the basing demand misses its mark. I also briefly suggest that there is an alternative way of defending the (...) basing demand. The alternative way is reconciliatory: it shows that most epistemologists may have been right to insist on such a demand, but perhaps still wrong to treat it as a dialectically powerful tool in the assessment of certain substantive epistemological theories.
