Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Appendix 1 was incomplete in the initial online publication. The original article has been corrected.

The finding that intuitions about the reference of proper names vary cross-culturally was one of the early milestones in experimental philosophy. Many follow-up studies investigated the scope and magnitude of such cross-cultural effects, but our paper provides the first systematic meta-analysis of studies replicating. In the light of our results, we assess the existence and significance of cross-cultural effects for intuitions about the reference of proper names.

In the last decade, many problematic cases of scientific conduct have been diagnosed; some of which involve outright fraud others are more subtle. These and similar problems can be interpreted as caused by lack of scientific objectivity. The current philosophical theories of objectivity do not provide scientists with conceptualizations that can be effectively put into practice in remedying these issues. We propose a novel way of thinking about objectivity for individual scientists; a negative and dynamic approach.We provide a philosophical conceptualization (...) of objectivity that is informed by empirical research. In particular, it is our intention to take the first steps in providing an empirically and methodologically informed inventory of factors that impair the scientific practice. The inventory will be compiled into a negative conceptualization, which could in principle be used by individual scientists to assess objectivity of scientific practice. We propose a preliminary outline of a usable and testable instrument for indicating the objectivity of scientific practice. (shrink)

William James was zo'n veelzijdig denker dat hij lezers met de meest uiteenlopende achtergronden wist te bereiken. Een opstel als ‘Is life worth living’ uit The Will to Believe spreekt waarschijnlijk andere lezers aan dan de discussies over het pragmatische waarheidsbegrip uit The meaning of truth. De auteur die fameuze passages leverde over ‘de theorie van de automaat’ is ook de schrijver die probeerde om bezwaren tegen een leven na de dood te pareren, en het is moeilijk om je een (...) hedendaagse lezer voor te stellen die beide thema's even serieus neemt.

This article discusses new material, published in volume 12 of the Collected Papers of Albert Einstein, that addresses Einstein’s knowledge of the Michelson–Morley experiment prior to 1905: in a lecture in Chicago in 1921, Einstein referred to the experiment, mentioned when he came upon it and hinted at its influence. Arguments are presented to explain the contrast with Einstein’s later pronouncements on the role of the experiment.

Why did Einstein tirelessly study unified field theory for more than 30 years? In this book, the author argues that Einstein believed he could find a unified theory of all of nature's forces by repeating the methods he used when he formulated general relativity. The book discusses Einstein's route to the general theory of relativity, focusing on the philosophical lessons that he learnt. It then addresses his quest for a unified theory for electromagnetism and gravity, discussing in detail his efforts (...) with Kaluza-Klein and, surprisingly, the theory of spinors. From these perspectives, Einstein's critical stance towards the quantum theory comes to stand in a new light. This book will be of interest to physicists, historians and philosophers of science.

'Holographic' relations between theories have become a main theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by Gerard 't Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic 'AdS/CFT' duality was introduced, which since has been heavily studied in the string theory community and beyond. Recently, Erik Verlinde has proposed (...) that even Newton's law of gravitation can be related holographically to the thermodynamics of information on screens. We discuss inter-theoretical relations in these scenarios: what is the status of the holographic relation in them and in what sense is gravity, or spacetime, emergent? (shrink)

Een van de hoekstenen van het idee dat de wetenschap een eenheid is, wordt gevormd door de overtuiging dat er in haar rijk één taal wordt gesproken: de taal van de feiten. Natuurlijk zijn er tussen de wetenschappen ook grote verschillen, maar die betreffen volgens deze overtuiging het gebied van de theorieën. De data waarop deze zich baseren, zouden neutraal geformuleerd kunnen worden. Als dit niet zo zou zijn, wordt ons het angstbeeld van een grote spraakverwarring voorgehouden.

ABSTRACTThis article reviews Zhu Xueqin’s writings on Jean-Jacques Rousseau against the background of the reception of Rousseau in China since the late nineteenth century. Rousseau was both an advocate and critic of the Enlightenment, and his work hence appealed to many Chinese intellectuals who struggled with the conundrum of how to modernize. During the late nineteenth century, Chinese supporters of Rousseau drew on his work to defend the viability of revolution. During the 1990s, following the tragedy of Tiananmen and the (...) decline of socialism, Rousseau served to reflect on China’s twentieth-century trajectory and the disastrous political consequences of collective moral idealism. For Zhu Xueqin, a key question was: Why were the French Revolution and the Cultural Revolution so similar? (shrink)

During World War II, Niels Bohr realized that the nature of war had changed irrevocably due to the introduction of the atomic bomb. This, in his opinion, meant that nation states had to be open about nuclear knowledge and negotiate toward peace. The bomb presented a threat, yet at the same time, an opportunity, as Bohr would argue in his characteristic way. It is not too difficult to point to the epistemological origin of Bohr’s argument: One easily identifies resonances with (...) his ideas on “complementarity” from quantum mechanics. According to Bohr’s doctrine of complementarity, a quantum mechanical object shows certain qualities depending on the experimental perspective from which it is studied; and these qualities may be mutually exclusive. However, they should in fact be looked upon as “complementary” properties that together make up the full picture of the object under investigation.Initially, Bohr could express his ideas to the highest circles of power. This would soon change, howe .. (shrink)

This slender and interesting volume by three Dutch philosophers examines the manner in which eight prominent philosophers dealt with ostensibly paranormal experiences arising both spontaneously and also as the result of hypnosis. Hans Gerding covers both Immanuel Kant and Arthur Schopenhauer; Rico Sneller discusses Friedrich Joseph Schelling, Hans Driesch, and Gabriel Marcel; and Hein van Dongen considers William James, Henri Bergson, and Jacques Derrida. My guess is that JSE readers might already know about Kant’s apparent ambivalence (or perhaps just (...) change of heart) about Swedenborg’s vision of a Stockholm fire (and his other reported experiences), as well as William James’s investigations of mental mediumship (Mrs. Piper in particular) and his experiments with altered states. Nevertheless, I expect they will find much that they didn’t already know in those chapters, as well as in the others of course. (shrink)

This study modelled associations between gender, ruminative cognitive style, alcohol use, and the time course of negative affect over the course of 43,111 random assessments in the natural environment. Participants completed 49 days of experience sampling over 1.3 years. The data indicated that rumination at baseline was positively associated with alcohol dependence symptoms at baseline as well as higher negative affect over the course of the study. Consistent with negative reinforcement models, drinking served to decrease the persistence of negative affect (...) from moment to moment. However, this ameliorative effect of drinking was evident only among women, suggesting an increased risk for negative reinforcement driven drinking behaviour. In addition, rumination appeared to counteract the desired effects of alcohol on mood among women. This suggests that women who ruminate more may be motivated to consume larger amounts of alcohol to achieve the desired effects. Overall, the results indicate that ruminative cognitive style and the persistence of negative affect from moment to moment may reflect an individual vulnerability for the development of alcohol use disorder especially among women.

This article discusses the body of work produced in the 1920–1930s by the Cosmist philosophers Alexander Gorsky, Nikolai Setnitsky, and Valeryan Muravyov as a representative case of the interaction between philosophy and literature typical for the Russian culture in the nineteenth to twentieth centuries. The article demonstrates how the synthesizing nature of the Cosmists’ creative thought, along with the multiplicity of their cultural roles, led to their use of genre forms which combined two types of writing, the literary and (...) the philosophical, namely, philosophical mystery plays, philosophical poems, aphorisms, and fragments. In addition, their aesthetic views and creative productions are shown in connection with the philosophical legacy of Nikolai Fedorov, who explored the notions of “projective culture,” of history as salvatory work, and of art as a re-creation of life. This study of poetry and prose of Gorsky, Setnitsky and Muravyov reveals the links between their aesthetic views, which were based on the notion of “cultural Central Image”, and their creative practices.
