Arrow’s axiomatic foundation of social choice theory can be understood as an application of Tarski’s methodology of the deductive sciences—which is closely related to the latter’s foundational contribution to model theory. In this note we show in a model-theoretic framework how Arrow’s use of von Neumann and Morgenstern’s concept of winning coalitions allows to exploit the algebraic structures involved in preference aggregation; this approach entails an alternative indirect ultrafilter proof for Arrow’s dictatorship result. This link also connects Arrow’s seminal result (...) to key developments and concepts in the history of model theory, notably ultraproducts and preservation results. (shrink)

In recent years, governments in a large number of countries have introduced so-called deployment policies to foster the diffusion of clean energy technologies. While there is little doubt that these demand-side measures have been very effective in raising the share of clean electricity generation, currently, much less is known about how deployment policies affect—and are affected by—technological innovation beyond the mere diffusion of existing technologies. Against this backdrop, this dissertation abstract and commentary presents the dissertation work of Dr. Joern Hoppmann. (...) Based on a discussion of deployment policies as a means for addressing pressing societal issues, the dissertation abstract describes four essays that provide a detailed account of the role that these policies play for technological learning in the solar photovoltaic industry. The theoretical background, methods, and main findings of each of the essays are briefly summarized. Building on this, this abstract discusses implications for managers and policy makers in terms of how to improve the design of deployment policies and navigate businesses in policy-induced markets.

This is a collection of 13 essays honoring Steven Cahn, presented to him on the occasion of his 25th year as Professor of Philosophy at the City University of New York. The essays address issues concerning the teaching of philosophy, the responsibilities of professors, and the good life.

Val Plumwood’s 1993 paper, “The politics of reason: towards a feminist logic” (hence- forth POR) attempted to set the stage for what she hoped would begin serious feminist exploration into formal logic – not merely its historical abuses, but, more importantly, its potential uses. This work offers us: (1) a case for there being feminist logic; and (2) a sketch of what it should resemble. The former goal of Plumwood’s paper encourages feminist theorists to reject anti-logic feminist views. The paper’s (...) latter aim is even more challenging. Plumwood’s critique of classical negation (and classical logic) as a logic of domination asks us to recognize that particular logical systems are weapons of oppression. Against anti-logic feminist theorists, Plumwood argues that there are other logics besides classical logic, such as relevant logics, which are suited for feminist theorizing. Some logics may oppress while others may liberate. We provide details about the sources and context for her rejection of classical logic and motivation for promoting relevant logics as feminist.

Das Schleiermacher-Archiv ist primär ein begleitendes Publikationsorgan für die seit 1980 erscheinende Gesamtausgabe der Werke Friedrich Schleiermachers (KGA), welches Materialien und Untersuchungen veröffentlicht, die in engerer Beziehung zur KGA stehen. In Sammelbänden werden zudem Beiträge dokumentiert, die auf internationalen Schleiermacher-Kongressen vorgetragen worden oder in diesem Zusammenhang entstanden sind.

In this first volume of The Sylvan Jungle, the editors present a scholarly edition of the first chapter, "Exploring Meinong's Jungle," of Richard Routley's 1000-plus page book, Exploring Meinong's Jungle and Beyond. Going against the Quinean orthodoxy, Routley’s aim was to support Meinong’s idea that we can truthfully refer to non-existent and even impossible objects, like Superman, unicorns and the round-square cupola on Berkeley College. The tools of non-classical logic at Routley’s disposal enabled him to update Meinong’s project for a (...) new generation. This volume begins with an Introduction from Dominic Hyde, “The ‘Jungle Book’ in Context,” an essay that situates Exploring Meinong’s Jungle and Beyond historically. We provide the original Preface by Routley, followed by Chapter 1: “Exploring Meinong’s Jungle and Beyond.” In Chapter 2, Nicholas Griffin argues that Sylvan’s project was insufficiently radical with his essay, “Why the Original Theory of Items Didn’t Go Far Enough.” Sylvan revisits his position from this time in Chapter 3, with his article, “Re-Exploring Item-Theory.” Filippo Casati, who has worked in the Routley Archives then takes up the question of the future of Sylvan’s research program in his essay, “The Future Perfect of Exploring Meinong’s Jungle.” Iconic and iconoclastic Australian philosopher Richard Routley published Exploring Meinong’s Jungle and Beyond in 1980. This work has fallen out of print, yet without great fanfare it has influenced two generations of philosophers and logicians. (shrink)

Following Lauwers and Van Liedekerke (1995), this paper explores in a model-theoretic framework the relation between Arrovian aggregation rules and ultraproducts, in order to investigate a source of impossibility results for the case of an infinite number of individuals and an aggregation rule based on a free ultrafilter of decisive coalitions.

The book_ Fate, Time, and Language: An Essay on Free Will_, published in 2010 by Columbia University Press, presented David Foster Wallace's challenge to Richard Taylor's argument for fatalism. In this anthology, notable philosophers engage directly with that work and assess Wallace's reply to Taylor as well as other aspects of Wallace's thought. With an introduction by Steven M. Cahn and Maureen Eckert, this collection includes essays by William Hasker, Gila Sher, Marcello Oreste Fiocco, Daniel R. Kelly, Nathan Ballantyne, (...) Justin Tosi, and Maureen Eckert. These thinkers explore Wallace's philosophical and literary work, illustrating remarkable ways in which his philosophical views influenced and were influenced by themes developed in his other writings, both fictional and nonfictional. Together with _Fate, Time, and Language_, this critical set unlocks key components of Wallace's work and its traces in modern literature and thought. (shrink)

Just War scholarship has adapted to contemporary crises and situations. But its adaptation has spurned debate and conversation--a method and means of pushing its thinking forward. Now the Just War tradition risks becoming marginalized. This concern may seem out of place as Just War literature is proliferating, yet this literature remains welded to traditional conceptualizations of Just War. Caron E. Gentry and Amy E. Eckert argue that the tradition needs to be updated to deal with substate actors within the (...) realm of legitimate authority, private military companies, and the questionable moral difference between the use of conventional and nuclear weapons. Additionally, as recent policy makers and scholars have tried to make the Just War criteria legalistic, they have weakened the tradition's ability to draw from and adjust to its contemporaneous setting. The essays in The Future of Just War seek to reorient the tradition around its core concerns of preventing the unjust use of force by states and limiting the harm inflicted on vulnerable populations such as civilian noncombatants. The pursuit of these challenges involves both a reclaiming of traditional Just War principles from those who would push it toward greater permissiveness with respect to war, as well as the application of Just War principles to emerging issues, such as the growing use of robotics in war or the privatization of force. These essays share a commitment to the idea that the tradition is more about a rigorous application of Just War principles than the satisfaction of a checklist of criteria to be met before waging "just" war in the service of national interest.

As most engineering design proceeds by modifying past designs and reusing and adapting existing components and solution principles, a significant part of the knowledge engineers employ in design is encapsulated in the past designs they are familiar with. References to past designs, as well as encounters with them, serve to invoke the knowledge associated with them and constructed from them. This chapter argues that much of this knowledge is tacit consisting in and/or made available by the perceptual recognition of features (...) and situations, using a discussion of design margins to illustrate how engineers use tacit knowledge in reasoning about the properties of new designs.

In 1962, the philosopher Richard Taylor used six commonly accepted presuppositions to imply that human beings have no control over the future. David Foster Wallace not only took issue with Taylor's method, which, according to him, scrambled the relations of logic, language, and the physical world, but also noted a semantic trick at the heart of Taylor's argument. _Fate, Time, and Language_ presents Wallace's brilliant critique of Taylor's work. Written long before the publication of his fiction and essays, Wallace's thesis (...) reveals his great skepticism of abstract thinking made to function as a negation of something more genuine and real. He was especially suspicious of certain paradigms of thought-the cerebral aestheticism of modernism, the clever gimmickry of postmodernism-that abandoned "the very old traditional human verities that have to do with spirituality and emotion and community." As Wallace rises to meet the challenge to free will presented by Taylor, we witness the developing perspective of this major novelist, along with his struggle to establish solid logical ground for his convictions. This volume, edited by Steven M. Cahn and Maureen Eckert, reproduces Taylor's original article and other works on fatalism cited by Wallace. James Ryerson's introduction connects Wallace's early philosophical work to the themes and explorations of his later fiction, and Jay Garfield supplies a critical biographical epilogue. (shrink)

Pipe flow has been a challenge that gave rise to investigations on turbulence—long before turbulence was discerned as a research problem in its own right. The discharge of water from elevated reservoirs through long conduits such as for the fountains at Versailles suggested investigations about the resistance in relation to the different diameters and lengths of the pipes as well as the speed of flow. Despite numerous measurements of hydraulic engineers, the data could not be reproduced by a commonly accepted (...) formula, not to mention a theoretical derivation. The resistance of air flow in long pipes for the supply of blast furnaces or mine air appeared even more inaccessible to rational elaboration. In the nineteenth century, it became gradually clear that there were two modes of pipe flow, laminar and turbulent. While the former could be accommodated under the roof of hydrodynamic theory, the latter proved elusive. When the wealth of turbulent pipe flow data in smooth tubes was displayed as a function of the Reynolds number, the empirically observed friction factor served as a guide for the search of a fundamental law about turbulent skin friction. By 1930, a logarithmic “wall law” seemed to resolve this quest. Yet pipe flow has not been exhausted as a research subject. It still ranks high on the agenda of turbulence research—both the transition from laminar to turbulent flow and fully developed turbulence at very large Reynolds numbers. (shrink)

The primary purpose of this randomized controlled trial (RCT) was to evaluate the efficacy of an unguided, two-week internet-based training program to overcome procrastination, called ON.TOP. Because adherence is a typical problem among individuals who tend to procrastinate, especially with internet-based interventions, the secondary purpose of the present study was to investigate whether adding SMS support increases subjects’ frequency of engagement in training. In a three-armed RCT (N = 161), the effects of the intervention alone and intervention with daily SMS-support (...) were compared to a waiting list control condition in a sample of students. The primary outcome of interest was procrastination. The secondary outcome of interest was the extent of training behavior. Baseline (T0), immediate post-treatment (T1) and 8-week post-treatment (T2) assessments were conducted. Results indicated that procrastination decreased significantly only with intervention group with daily SMS support, relative to control. Moreover, incorporating SMS support also may enhance extent of training behavior. (shrink)

Detailed exploration of the Allegory of the Cave, utilizing notions from film studies, may provide us with insight regarding the identity of the puppet masters in Plato's allegory.

The effect of mechanical deformation on the formation of quasicrystals in Zr57Ti8Nb2.5Cu13.9Ni11.1Al7.5 glassy ribbons has been investigated. The mechanical treatment drastically affects the crystallization behavior and, in particular, suppresses primary quasicrystal formation. However, quasicrystals can be formed by the addition of the appropriate amount of zirconium. This indicates that if a particular short-range order (e.g., icosahedral) is required for quasicrystal formation and if this short-range order is altered during milling, it can be restored by appropriately adjusting the chemical composition.

Recent scholarship has tied duties of distributive justice to the existence of coercive institutions. This body of work argues that, because the international system lacks institutions that can coerce individuals in the same manner as domestic institutions, there are no international obligations to address relative poverty and inequality. Proponents of this view use it to support the existence of a compatriot preference that requires us to meet the needs of compatriots before meeting those of the global poor. Even supposing distributive (...) justice to be linked to coercion, coercive institutions do exist at the international level. These institutions coerce states rather than individuals, but their ability to coerce gives rise to duties of economic redistribution between states. (shrink)

Euthyphro is a Socratic interlocutor claiming enormous religious expertise, while his portrayal in the eponymous dialogue raises questions the reliability of his beliefs. This paper closely examines how Euthyphro justifies his case against his father, identifying an argument that relies on the concept of miasma (pollution). In so far as miasma is considered in isolation, Euthyphro has a good argument. Unfortunately, there is more than miasma at stake when considering why one could prosecute one’s own parent. Introducing the other relevant (...) concepts, honor and shame, we find his case reflects a dilemma at the source of ancient Greek religious thought. It would not be possible for Euthyphro or anyone else to know what to do in his case. (shrink)

ArgumentDuring the interwar period research on turbulence met with interest from different areas: in aeronautical engineering turbulence became a subject of experimental study in wind tunnels; in naval architecture and hydraulic engineering turbulence research was on the agenda because of its role for skin friction; applied mathematicians and theoretical physicists struggled with the problem to determine the onset of turbulence from the fundamental hydrodynamic equations; experimental physicists developed techniques to measure the velocity fluctuations of turbulent flows. In this paper I (...) describe the rise of turbulence in the 1920s and 1930s as a research field under the label of applied mechanics. Although the focus is on Germany, the international development of this research field is illuminated by the role which Ludwig Prandtl played as its acknowledged “chief” (G. I. Taylor). I argue that the multifaceted character of this research field calls for an epistemology and historiography which intrinsically takes the interaction of science and engineering into account.

This paper examines G. W. F. Hegel’s interpretation of Plato from his Lectures on the History of Philosophy, situating his interpretation historically and noting features that resonate with contemporary Plato scholarship. Hegel forms his interpretation prior to stylometric studies of the dialogues, and distinguishes his Plato from Wilhelm Gottlieb Tennemann and Friedrich Daniel Ernst Schleiermacher’s views. Hegel responds to important interpretive concerns: 1) the relationship between Socratic and Platonic thought, 2) the dialogue form, 3) Platonic Anonymity and 4) Platonic myth. (...) His treatment of these issues is illustrative with respect to understanding Hegelian philosophy and the history of Plato interpretation. (shrink)

The efflux problem deals with the outflow of water through an orifice in a vessel, the flow over the crest of a weir and some other ways of discharge. The difficulties to account for such fluid motions in terms of a mathematical theory made it a notorious problem throughout the history of hydraulics and hydrodynamics. The treatment of the efflux problem, therefore, reflects the diverging routes along which hydraulics became an engineering science and hydrodynamics a theoretical science out of touch (...) with applications. By the twentieth century, the presentation of the efflux problem in textbooks on hydraulics had almost nothing in common with that in textbooks on hydrodynamics. (shrink)

Under the experienced editorial guidance of Steven M. Cahn and Maureen Eckert, PHILOSOPHICAL HORIZONS introduces your students to the central issues of philosophy through an engaging combination of classic and contemporary sources. Placing a premium on accessibility for today’s beginning philosophy students, the editors have put together over seventy non-technical readings, many of which have been edited for maximum comprehensibility. Unlike any other introductory anthology of past and present readings, this text contains a dozen unabridged, fully annotated masterpieces from (...) the history of philosophy, including in their entirety Plato’s Euthyphro, Apology, and Crito, the Encheiridion of Epictetus, Descartes’s Meditations, Berkeley’s Treatise, Hume’s An Enquiry Concerning Human Understanding and Dialogues Concerning Natural Religion, Kant’s Groundwork, Mill’s Utilitarianism, James’s The Will to Believe, and Sartre’s The Humanism of Existentialism. Despite its wealth of material, the book is easily manageable in a semester-long course. By juxtaposing the work of historical and contemporary philosophers, the editors have emphasized both the timelessness and timeliness of philosophical inquiry. (shrink)

Agatha Christie’s Murder on the Orient Express remains well-read, and its hero Hercule Poirot continues to enjoy popular currency. Yet the text has not aged well due to some of its now clichéd plot developments and dialogue, as well as Christie’s depiction of class, ethnic and national prejudices in it and her other novels. This study hopes to re-energize discussion on Murder by finding defensible reasons for its apparent flaws. Not only do the stereotypical behaviors of the passengers narratively distract (...) Poirot and the reader from a solution, but their flaws serve as foils against which Poirot’s heroic gravitas and cultural values are positively contrasted. Further, criticism often misses the point that the passengers are performing their behaviors, and if so, the deployment of stereotypes as only acted performances destabilizes them as permanent aspects of national or ethnic identity. Can Murder then be read as an anti-racist text? (shrink)
