Discovering the underlying mathematical expressions describing a dataset is a core challenge for artificial intelligence. This is the problem of symbolic regression. Despite recent advances in training neural networks to solve complex tasks, deep learning approaches to symbolic regression are underexplored. We propose a framework that leverages deep learning for symbolic regression via a simple idea: use a large model to search the space of small models. Specifically, we use a recurrent neural network to emit a distribution over tractable mathematical (...) expressions and employ a novel risk-seeking policy gradient to train the network to generate better-fitting expressions. Our algorithm outperforms several baseline methods (including Eureqa, the gold standard for symbolic regression) in its ability to exactly recover symbolic expressions on a series of benchmark problems, both with and without added noise. More broadly, our contributions include a framework that can be applied to optimize hierarchical, variable-length objects under a blackbox performance metric, with the ability to incorporate constraints in situ, and a risk-seeking policy gradient formulation that optimizes for best-case performance instead of expected performance.

Among the philosophical and theological responses to the phenomenon of religious diversity, religious pluralism has been both prominent and influential. Of its various proponents, John Hick and John Cobb represent two important figures whose respective positions, especially that of Hick, have done much to shape the debate over religious pluralism. This article critically analyses their positions, arguing that, by unhelpfully homogenizing religious perspectives, each of them fails to do justice to the radical diversity that exists. As an alternative to these (...) homogenizing tendencies, the article builds upon D. Z. Phillips’ contemplative conception of philosophy to develop a radical pluralist approach, which prioritizes a deepening of understanding of religious diversity rather than the promotion of one’s own theological preferences.

Calls for decolonization are on the rise in social and academic life, but ‘decolonization’ can mean various things. This article expounds and critically evaluates the programme of conceptual decolonization, chiefly as promulgated in relation to African philosophy by Kwasi Wiredu. The programme involves both resisting the unreflective acceptance of non-indigenous concepts and constructively utilizing indigenous conceptual resources to address philosophical questions. Examining recent objections from Olúfẹ́mi Táíwò and giving particular attention to Wiredu’s treatment of religious concepts, I concur with Wiredu (...) that conceptual decolonization can encourage conceptual enlargement but argue that care is needed to avoid oversimplifying the non-indigenous concepts that are subjected to scrutiny.

This article questions the assumption, held by several philosophers, that the Epicurean argument for death's being ?nothing to us? must be fallacious since its acceptance would undermine the principle that killing is (in general) wrong. Two possible strategies are considered, which the Epicurean-sympathizer might deploy in order to show that the non-badness of death (for the person who dies) is compatible with killing's being wrong. One of these is unsuccessful; the other is more promising. It involves arguing that the wrongness (...) of killing is a ?basic moral certainty? and hence requires no underpinning by the judgement that death is bad. Problems for this proposal, and possible responses to those problems, are considered. Though the strategy is not decisive, it is deemed to be one that the Epicurean could plausibly adopt. (shrink)

This paper examines and classifies the computational complexity of model checking and satisfiability for hybrid logics over frames with equivalence relations. The considered languages contain all possible combinations of the downarrow binder, the existential binder, the satisfaction operator, and the global modality, ranging from the minimal hybrid language to very expressive languages. For model checking, we separate polynomial-time solvable from PSPACE-complete cases, and for satisfiability, we exhibit cases complete for NP, PS pace , NE xp T ime , and even (...) N2E xp T ime . Our analysis includes the versions of all these languages without atomic propositions, and also complete frames. (shrink)

Who owns nature? The question could be less important than reducing animal sufferings in nature. It does not matter if nature does not belong to anyone or if it belongs to someone, because in both cases there are limitations, linked with animal welfare, regarding what we should do in nature. Sentient beings have interests that we must take into account when designing environmental policies. Since neither ecosystems nor plants have interests, preserving nature is less important than reducing animal sufferings. The (...) relevant moral issue is, therefore, knowing what happens to sentient animals in nature and developing policies to reduce their sufferings. This implies that we have the moral obligation of intervening in nature with the aim of reducing animal sufferings, so conservationist environmental policies defended by ecologists are morally unacceptable.

the aim of this paper is to prove that secession is inherently undemocratic. We will review the secessionist arguments: the one that starts from a wrong idea of selfgovernment and the one that starts from liberalism. then, we will oppose objections to both: defending the value of equality; rejecting internal homogeneity claims; picking up Buchanan’s classic objections; and finally, reformulating, with Habermas and Pogge, a concept of self-government in order to deduce that it is not legitimate to draw more boundaries (...) because an ideal democracy would require to eliminate the current borders.

In this paper, we explore the concept of bearing witness in nursing practice. We examine the description of bearing witness in the nursing literature, particularly that offered by William Cody who suggests that bearing witness results in the limited moral obligation of “true presence.” We then turn to Lorraine Code's work on testimony, drawing parallels between the concepts of testimony and bearing witness. Code suggests that receiving testimony results in a responsibility to respond, and that this is an ethico‐political obligation. (...) We discuss these ideas in relation to a Canadian exemplar of witnessing the Truth and Reconciliation Commission of Canada's work to understand and address the historical injustices done to Indigenous peoples in Canada. Here, we focus on the Commission's definition of witnessing and highlight the experience of Shelagh Rogers who served as an honorary witness. As an outcome of our analysis, we suggest that bearing witness in nursing practice is most usefully conceptualized as both a moral and a political obligation. Implications for nursing practice are suggested, including first, the need to critically examine our own understandings of power and privilege in order to authentically bear witness and avoid being complicit in injustice, and second, the concomitant responsibility to take action to challenge injustice once we have borne witness to it.

The debate between the Better and the Worse Argument, between the old and the new education, in Aristophanes’ Clouds, is a scene full of caustic humour and exquisite irony. In this paper we will try to provide a detailed analysis of the linguistic features that characterize these two characters, in order to confront how two clearly opposite linguistic registers are outlined, in line with their confrontation of ideas. In general terms, the Better Argument exhibits a stronger conversational tone than his (...) adversary, a greater inclination to the use of asyndeton in his syntax, more vulgar and abusive terms, a virtual absence of both poetic and paratragic words and certain linguistic innovations and variants of a lesser literary quality. In contrast, the Worse Argument does just the opposite. (shrink)

This paper responds to Severin Schroeder's recent charge that Wittgenstein's philosophy of religion contains an ‘unresolved tension’ between three propositions, namely: (1) ‘As a hypothesis, God's existence (&c) is extremely implausible’; (2) ‘Christian faith is not unreasonable’; and (3) ‘Christian faith does involve belief in God's existence (&c)’. I argue as follows: that the first of these propositions has no place in Wittgenstein's thinking on religion; that the second is ill-phrased and should be re-worded as the proposition that ‘Christian faith (...) is neither unreasonable nor reasonable’; and that the third proposition (contrary to what Schroeder seems to assume) tells us nothing about the nature of the objects of religious belief. It follows from my argument that Schroeder has not exposed a tension in Wittgenstein's thoughts on religion. I end with some positive remarks about Wittgenstein's method. (shrink)

The study we report in this article addresses the results of comparing the rhetorical trees from two different languages carried out by two annotators starting from the Rhetorical Structure Theory. Furthermore, we investigate the methodology for a suitable evaluation, both quantitative and qualitative, of these trees. Our corpus contains abstracts of medical research articles written both in Spanish and Basque, and extracted from Gaceta Médica de Bilbao. The results demonstrate that almost half of the annotator disagreement is due to the (...) use of translation strategies that notably affect rhetorical structures. (shrink)

Rebirth and the Stream of Life explores the diversity as well as the ethical and religious significance of rebirth beliefs, focusing especially on Hindu and Buddhist traditions but also discussing indigenous religions and ancient Greek thought. Utilizing resources from religious studies, anthropology and theology, an expanded conception of philosophy of religion is exemplified, which takes seriously lived experience rather than treating religious beliefs in isolation from their place in believers' lives. Drawing upon his expertise in interdisciplinary working and Wittgenstein-influenced approaches, (...) Mikel Burley examines several interrelated phenomena, including purported past-life memories, the relationship between metaphysics and ethics, efforts to 'demythologize' rebirth, and moral critiques of the doctrine of karma. This range of topics, with rebirth as a unifying theme, makes the book of value to anyone interested in philosophy, the study of religions, and what it means to believe that we undergo multiple lives.

Via a discussion of various ways in which putative descriptions or explanations can be deemed to be morally insensitive, this article investigates the role of “contemplation” in philosophy of religion and ethics, and especially in connection with the “problem of evil.” Focusing on the Wittgenstein-influenced methods of D. Z. Phillips, the question is considered whether a tension obtains between, on the one hand, a “contemplative conception of philosophy,” and on the other hand, the sort of critique of theodicy according to (...) which the theodicist’s attempt to maintain a contemplative stance with respect to evil and suffering is morally corrupt.

"This collection of essays on aesthetics is the first set of Dufrenne's shorter pieces to appear in English. It is arranged thematically and includes works from as early as 1948 to as late as 1974.... In these essays Dufrenne covers a lot of ground and draws into his discussion of aesthetics a whole range of thinkers, including Barthes, Foucault, Lyotard, Metz, Freud and Derrida.... These essays are well worth reading both for the quality of the writing and for the continual (...) insights which come to the surface along the way. The text has been devotedly translated and a helpful introduction has been added." -- David Pollard, British Journal of Aesthetics. (shrink)

La presente obra navega entre dos conceptos —la heterotopía y la utopía— en el contexto de la posmetrópolis. La heterotopía, tal y como explican en el prefacio los coeditores, ha atraído una innegable atención en el ámbito de las ciencias sociales desde que Foucault trasladara el concepto del ámbito médico al espacial. Frente al no espacio de la utopía y su carácter ideal y regulador, las heterotopías serían lugares reales, en los que la diferencia se manifiesta al invertir y subvertir (...) aquellos órdenes que configuran nuestros espacios cotidianos. Siendo uno de estos lugares cotidianos la ciudad, y atendiendo a las posibilidades emancipatorias y reactivas que pronto se asociaron a lo heterotópico, cabe preguntarse por el estado actual de las heterotopías urbanas: ¿son las heterotopías actuales, como registra el título de la obra, utopías liberales? León Casero y Urabayen ofrecen en el prefacio un amplio panorama al respecto. (shrink)

D.Z. Phillips’ work in the philosophy of religion continues to be criticised, often on the basis of serious misunderstandings. By engaging with criticisms of Phillips’ Wittgenstein-influenced approach, especially those recently exemplified by Graham Oppy and Nick Trakakis, this article seeks to clarify what Phillips’ approach does and does not involve. Focusing on the relation between talk of God’s reality and talk of matters of fact, and on the question whether God is a ‘metaphysical reality’, the extent to which Phillips himself (...) emphasised the need for close attention to how language is used in real-life situations is highlighted, and the persistent mischaracterisation of Phillips as a ‘non-realist’ is rejected.

Philosophy of religion is a popular area of study with a lot of underexplored potential. For many students, as well as members of the public, it is the area of philosophy that deals most explicitly with the “big questions” that engage them directly. But a preoccupation with overly technical argumentation and decontextualized examples of religious beliefs can be off-putting. In this article, I discuss broader and narrower visions of philosophy of religion, outlining what needs to be included in any introductory (...) course while also exploring ways of diversifying the syllabus and deepening approaches to existing topics for more advanced-level students. Without overlooking the risks of spreading the content too thinly, I highlight how increased interdisciplinarity and greater cross-cultural awareness can enliven the subject. (shrink)

The received wisdom among welfare state scholars is that policy feedbacks render social insurance programs durable. Yet, in the case of Detroit’s municipal bankruptcy, a voting majority of retired city workers accepted a settlement that asked them to waive key legal protections, formally accept gutted medical benefits, trimmed pension benefits, and a new public-private pension financing mechanism. This article synthesizes interactionist theories of loss to introduce the concept of “collective cooling.” I argue that collective cooling helps to establish the limits (...) of policy feedbacks by explaining how a group of retirees’ collective self-understandings were adjusted from that of contractual rights holders to charitable dependents. Key components of this process included: First, seeking to adjust understandings of how pensioners were perceived by powerful outsiders; And, second, seeking to adjust the loss from one that reflected poorly on pensioners to one that did not. Implications are discussed for how people accept unexpected economic losses, especially those imposed by a trusted institution such as an employer or government organization. (shrink)

Junto a historiadores o periodistas, también los cineastas han tratado de ofrecer una perspectiva válida y valiosa sobre el pasado. Los episodios más extremos de violencia política, incluidos los genocidios y el terrorismo han sido llevados al cine con diferente éxito. Este artículo analiza algunas de las películas más recientes sobre el tema. Por un lado, aborda el debate ético sobre los efectos reales y posibles de la representación de la violencia política, especialmente el riesgo de espectacularización y estetización de (...) la violencia, la crueldad y el dolor en las imágenes artísticas. Por otro lado, reflexiona sobre la posibilidad de una educación estética a través del arte, el poder del arte de tratar lo inefable y de reconocer y llevar al reconocimiento del daño infligido a las víctimas.  .

My dissertation deals with the Master Argument of Diodorus Cronus, a contemporary of Aristotle's. The argument was one of the most famous pieces of temporal and modal reasoning in ancient philosophy. It purports to prove that a proposition is possible if and only if it is true or will be true. The argument runs as follows: Everything that is past and true is necessary; The impossible does not follow the possible; Therefore, nothing is possible which neither is nor will be (...) true. Unfortunately, all accounts of the Master that have survived are so sketchy that we cannot determine whether the argument is valid or not. ;Several reconstructions of Diodorus' argument have been proposed. The purpose of the reconstructions is to show, using the resources of modal and tense logics, that the argument is valid. I analyze and critique most of these proposals, arguing in the final chapter for a new reconstruction which I believe to be more defensible than existing ones. ;The Master Argument is important for several reasons. It elicited much discussion among ancient philosophers and logicians both because of its reduction of modal logic to tense logic and its bearing on the free will/determinism debate. But, its influence also extends to contemporary philosophy and logic. In the 1950s and 60s, the Master inspired formal work on Diodorean systems. Much of the work on the calculus of tenses, e.g., by Prior, was undertaken in view of investigating Diodorus' argument. Finally, the literature that the argument has spawned has enriched and deepened our understanding of the connections between matters modal and temporal. (shrink)

Abstract: Critics of Havi Carel's 2008 book, Illness: The Cry of the Flesh, have contended that Carel's deployment of phenomenological philosophy adds little to commonsense views about illness and that Carel relies too heavily on emotion-laden autobiographical anecdotes. Against these contentions this article argues: first, that a perfectly respectable task of philosophy is to find reasons to support pre-existing beliefs; and secondly, that Carel's use of anecdotes, while certainly appealing to readers' emotions, constitutes part of a legitimate argumentative strategy. The (...) article links these proposals with broader debates concerning the proper task of philosophy and the role of emotionality and imagination in philosophical inquiry. (shrink)

In his article 'The Evil of Death' (henceforth: ED) Harry Silverstein argues that a proper refutation of the Epicurean view that death is not an evil requires the adoption of a particular revisionary ontology, which Silverstein, following Quine, calls 'four-dimensionalism'.1 In 'The Evil of Death Revisited' (henceforth: EDR) Silverstein reaffirms his earlier position and responds to several criticisms, including some targeted at his ontology. There remain, however, serious problems with Silverstein's argument, and I shall highlight five major ones below. I (...) conclude that Silverstein has not shown that an appeal to four-dimensionalism facilitates a refutation of Epicurus, although a consideration of some of Silverstein's points helps to indicate the limited scope of the Epicurean thesis.

Samkhya and Yoga are two of the oldest and most influential systems of classical Indian philosophy. This book provides a thorough analysis of the systems in order to fully understand Indian philosophy. Placing particular emphasis on the metaphysical schema which underlies both concepts, the author aptly develops a new interpretation of the standard views on Samkhya and Yoga. Drawing upon existing sources and using insights from both eastern and western philosophy and religious practice, this comprehensive interpretation is respectful to the (...) underlying spiritual purpose of the Indian systems. It serves to illuminate the relation between the theoretical and practical dimensions of Samkhya and Yoga. The book fills a gap in current scholarship. It will be of interest to those concerned with Indology as well as philosophies in general and their similarities and differences with other traditions. (shrink)
