Velázquez’s Democritus (ca. 1630) presents a unique encounter: not only are there few depictions in which the Greek philosopher appears with a sphere that shows an actual map, but Velázquez used a court jester as a model for Democritus, thus placing the philosopher within a courtly space. When we study the painting in relation to the literary interests of the Spanish Golden Age and its socio-political circumstances, we can see the figure of Democritus as far from just another instantiation of (...) a conventional trope. The philosopher’s smile and his crepuscular globe entrap the viewer in a semiotic game with pedagogical and ethical goals. While the scholarship on the painting has dwelt extensively on the identification of the figure, this essay moves beyond the superficial aspects of subject identity in order to explore how the painting articulates and requests a profoundly philosophical engagement. I thus examine Democritus in relation to contemporary literary and philosophical themes, many of which were present in Velázquez’s own personal library: the period’s understanding of the philosopher, cartographic spheres, and treatises on laughter. Considered in this manner, Velázquez’s figure is not responding to the folly of humanity in general, as is commonly the case in representations of the philosopher, but is rather presented through a courtly prism in which conquest, geography, and politics are inescapably interrelated. Velázquez’s Democritus emphasizes the philosophical and moral qualities of a learned and decorous laughter, which performs a critical and ethical role framed by Spain’s political difficulties.

States restrict immigration on a massive scale. Governments fortify their borders with walls and fences, authorize border patrols, imprison migrants in detention centers, and deport large numbers of foreigners. Unjust Borders: Individuals and the Ethics of Immigration argues that immigration restrictions are systematically unjust and examines how individual actors should respond to this injustice. Javier Hidalgo maintains that individuals can rightfully resist immigration restrictions and often have strong moral reasons to subvert these laws. This book makes the case that (...) unauthorized migrants can permissibly evade, deceive, and use defensive force against immigration agents, that smugglers can aid migrants in crossing borders, and that citizens should disobey laws that compel them to harm immigrants. Unjust Borders is a meditation on how individuals should act in the midst of pervasive injustice. (shrink)

Many organisations in rich countries actively recruit health workers from poor countries. Critics object to this recruitment on the grounds that it has harmful consequences and that it encourages health workers to violate obligations to their compatriots. Against these critics, I argue that the active recruitment of health workers from low-income countries is morally permissible. The available evidence suggests that the emigration of health workers does not in general have harmful effects on health outcomes. In addition, health workers can immigrate (...) to rich countries and also satisfy their obligations to their compatriots. It is consequently unjustified to blame or sanction organisations that actively recruit health workers. (shrink)

I am very grateful to the five commentators for taking the time to respond to my article ‘The Active Recruitment of Health Workers: A Defense’.1 I have learned a great deal from each of their commentaries, and I am sorry to say that I will be unable to address all their important comments and criticisms in detail. In this response, I will focus on replying to the commentators’ major objections.In my paper, I suggested that the emigration of health workers from (...) poor countries might not have harmful effects on health outcomes in general, or may only have relatively small negative effects in a wide range of cases. Several commentators challenge my analysis. Carwyn Rhys Hooper suggests that it is prima facie plausible that the emigration of health workers causes harm, and that there is insufficient evidence to reject this claim.2 Gilian Brock3 and Iain Bassington4 argue that my paper failed to consider the full range of possible harms that the active recruitment of health workers brings about. These commentators are correct in that we need more evidence about the effects of migration, and that it may be too soon to arrive at the all-things-considered judgment that the emigration of health workers does not generally enable serious harm.Nonetheless, I believe that the active recruitment of health workers is still permissible. For one thing, I am less confident than Brock that the empirical research on skilled migration clearly establishes that the migration of skilled professionals causes harm to sending countries. There is a sizable body of empirical research that is inconsistent with many of Brock's claims. It is not obvious that the emigration of skilled workers depletes human capital in the sending country.5 ,6 In fact, there is evidence that the opportunity to emigrate …. (shrink)

Aristotle's Ethics develops a complex theory of the qualities which make for a good human being and for several decades there has been intense discussion about whether Aristotle's theory of voluntariness, outlined in the Ethics, actually delineates what modern thinkers would recognize as a theory of moral responsibility. Javier Echeñique presents a novel account of Aristotle's discussion of voluntariness in the Ethics, arguing - against the interpretation by Arthur Adkins and that inspired by Peter Strawson - that he developed (...) an original and compelling theory of moral responsibility and that this theory has contributed in important ways to our understanding of coercion, ignorance and violence. His study will be valuable for a wide range of readers interested in Aristotle and in ancient ethics more broadly. (shrink)

This article examines the 2008 report of the Quebec Government’s Consultation Commission on Accommodation Practices Related to Cultural Differences which was co-authored by Charles Taylor. Summarizing its main themes, it identifies points of intersection with Taylor’s political thought. Issues of citizen equality, including gender equality, secularism, integration and interculturalism, receive special attention.

Hicrî birinci yüzyılın sonu ile ikinci yüzyılın ortalarında yaşamış bulunan Ca‘fer-i Sâdık ve Ebû Hanîfe, akran iki âlimdir. Kûfe’de yetişen ve Ehl-i sünnet mezheplerinden birinin imamı olan Ebû Hanîfe’nin, Medine’de yetişen ve İsnâaşeriyye’nin altıncı imamı kabul edilen Ca‘fer ile bir araya geldiği ve onun talebesi olduğu hem sünnî hem Şiî kaynaklarda rivayet edilmektedir. Mukaddem kaynaklarda Ebû Hanîfe’nin Ca‘fer-i Sâdık’ın öğrencisi olduğu yönündeki ifadelerin, muahhar kaynaklarda abartılı bir şekilde yorumlandığı görülmüştür. Bu çalışmada Ebû Hanîfe ile Ca‘fer-i Sâdık arasındaki hoca-talebe ilişkisi netleştirilmeye (...) çalışılmıştır. Bu sebeple öncelikle kısaca her iki imamın hayatı ele alınarak onların ilmî birikimi tespit edilmiştir. Akabinde Ebû Hanîfe ile Ca‘fer’in ne zaman ve ne kadar süre birlikte oldukları, Ebû Hanîfe’nin Ehl-i beyt’e yönelik tutumunun Ca‘fer’den ilim almasında ne gibi bir etkisinin bulunduğu ve çeşitli ilim dallarında Ebû Hanîfe- Ca‘fer ilişkisi tespit edilmeye çalışılmıştır.

Developments in biosemiotics and democratic theory enable renewed appreciation of the possibilities for ecological democracy. Semiotics is the study of sign processes in meaning-making and communication. Signs and meanings exist in all living systems, and all living systems are therefore semiotic systems. Ecological communication can involve abiotic and biotic communication, including human language, facilitating an integration of politics and ecology in the form of ecological democracy encompassing communicative networks in nature and human society.

We prove Menger’s theorem for countable graphs in ${{\Pi^1_1\tt{-CA}_0}}$ . Our proof in fact proves a stronger statement, which we call extended Menger’s theorem, that is equivalent to ${{\Pi^1_1\tt{-CA}_0}}$ over ${{\tt{RCA}_0}}$.

Most interpretations of Quantum Mechanics alternative to Copenhagen interpretation try to avoid the dualistic flavor of the latter. One of the basic goals of the former is to avoid the ad hoc introduction of observers and observations as an inevitable presupposition of physics. Non-Copenhagen interpretations usually trust in decoherence as a necessary mechanism to obtain a well-defined, observer-free transition from a unitary quantum description of the universe to classicality. Even though decoherence does not solve the problem of the definite outcomes, (...) it helps to explain why we do not observe superpositions and, according to Zurek’s existential interpretation, why a specific preferred basis emerges through system–environment interactions. The aim of this paper is to show why such interpretation ends up begging the question and provides little progress in understanding the quantum-to-classical transition; the ultimate reason being that preferred bases always correlate to human observation. Benefitting from the technical discussion, some remarks will be offered in the last section regarding the role of classical observations as a necessary condition to make workable the formalism of Quantum Mechanics and scientific activity itself.

“There’s Plenty of Room at the Bottom”, said the title of Richard Feynman’s 1959 seminal conference at the California Institute of Technology. Fifty years on, nanotechnologies have led computer scientists to pay close attention to the links between physical reality and information processing. Not all the physical requirements of optimal computation are captured by traditional models—one still largely missing is reversibility. The dynamic laws of physics are reversible at microphysical level, distinct initial states of a system leading to distinct final (...) states. On the other hand, as von Neumann already conjectured, irreversible information processing is expensive: to erase a single bit of information costs ~3 × 10−21 joules at room temperature. Information entropy is a thermodynamic cost, to be paid in non-computational energy dissipation. This paper addresses the problem drawing on Edward Fredkin’s Finite Nature hypothesis: the ultimate nature of the universe is discrete and finite, satisfying the axioms of classical, atomistic mereology. The chosen model is a cellular automaton with reversible dynamics, capable of retaining memory of the information present at the beginning of the universe. Such a CA can implement the Boolean logical operations and the other building bricks of computation: it can develop and host all-purpose computers. The model is a candidate for the realization of computational systems, capable of exploiting the resources of the physical world in an efficient way, for they can host logical circuits with negligible internal energy dissipation.

The systematic importance of the eidetic account of phantasy for Husserlian phenomenology in general is undisputed, but whether this account can be relevant for Aesthetics has often been put into question. In this paper I argue that Husserl’s rich phenomenology of phantasy, and in particular his account of perceptual phantasy, can nevertheless significantly enhance our understanding of how we recognize and imaginatively participate in artistic fictions. Moreover, I show how Husserl’s peculiar formulation of a non-intuitive phantasy at stake in artistic (...) representation anticipates some uses of the imagination in Aesthetics suggested by Ernst Gombrich and Kendall Walton.

In this paper I argue against Armstrong’s recent truthmaking account of possibility. I show that the truthmaking account presupposes modality in a number of different ways, and consequently that it is incapable of underwriting a genuine reduction of modality. I also argue that Armstrong’s account faces serious difficulties irrespective of the question of reduction; in particular, I argue that his Entailment and Possibility Principles are both false.

ABSTRACTIn this article, I will identify two key normative principles at the core of Robert L. Simon’s mutualist theory of sport, namely, the respect-for-the-opponent principle and the idea that sport is a practice aimed at pursuing excellence. The former is a Kantian principle grounded in human beings’ rationality, and the latter is an Aristotelian principle related to the development of excellences as a means to human flourishing. After having presented and analyzed both principles, I will critically evaluate Simon’s attempt to (...) combine them within his mutualist approach. To conclude, I will highlight the challenges that mutualism should face to complete such a combination more successfully.Abbreviation: Categorical imperative. (shrink)

In this commentary on Stokoe’s article, ‘Moving forward with membership categorization analysis’, I take up the challenge to apply her keys for MCA to an extract of conversation recorded in a restaurant. The strengths of conversation analysis have not included – and indeed have not attempted to achieve – successful engagement with beyond-the-immediate-talk aspects of culture and the commonsense workings of society. The aim of the article is to explore what MCA might add to an analysis of a stretch of (...) talk using conversation analytic tools. It was found that a systematic application of the keys did indeed provide a richer account of what was going on. Whereas categories alone did not appear to provide more insights than commonsense can tell us, when the broader array of MCA tools and keys were applied, an enhanced analysis of the passage of talk emerged. An exploration of whether this can be extended as a method for a rigorous investigation of culture and society while still being grounded in participants’ mutual, moment-by-moment orientations to categories seems at the very least worth the serious attention of scholars interested in interaction.

ABSTRACT The paper examines the little-known experiments in audition performed by the prominent experimental physiologist Jan Purkyně in Prague in the 1850s. Purkyně’s original research on spatial hearing and auditory attention is studied against the backdrop of the nineteenth century research on binaural audition and the nascent field of psychophysics. The article revolves around an acoustic research instrument of Purkyně’s own making, the opistophone, in which hearing became both an object of investigation and an instrument of scientific inquiry. It argues (...) that Purkyně’s understanding of auditory attention, which combined acoustic stimulation, physiological conditions, and sensory training, preceded a similar approach to hearing in psychophysical debates in the second half of the nineteenth century. Purkyně was the first scholar to experimentally investigate intracranial sounds, which he studied in his experiments with the inmates of the Prague Institute of Deaf-Mutes. This research on intracranial hearing was part of Purkyně’s study of so-called organic subjectivity, in which subjective hearing experience was interpreted as the result of the interaction between individual perception and objective acoustic phenomena.

Political philosophy in the last decades has turned away from universal narratives of progress, on grounds that these narratives produce exclusion and justify domination. However, the universal values that underlie emancipatory political projects seem to presuppose universal history, which explains its persistence in some contemporary political philosophers committed to such projects. In order to find a response to the paradox according to which universal history is inherently exclusionary and yet necessary to uphold universal values, I examine the contrast between Adorno’s (...) and Lyotard’s perspectives on the problem of writing history ‘after Auschwitz’. For both philosophers, Auschwitz interrupts our fundamental normative and cognitive values, because any attempt to identify the meaning of the camps by means of these values misunderstands the suffering that took place in them. Yet this interruption produces a feeling that calls for the institution of new universal normative values. For Adorno, this value is a purely negative command to act in such a way that Auschwitz does not repeat itself. For Lyotard, by contrast, it is the demand to invent new idioms that make it possible to find meaning in Auschwitz. (shrink)
