In this study, a new mathematical model is presented to solve the flexible flow shop problem where transportation is reliable and there are constraints on intermediate buffers, budgets, and human resource learning effects. Firstly, the model is validated to confirm the accuracy of its performance. Then, since it is an NP-hard one, two metaheuristic algorithms, namely, MOSA and MOEA/D, are rendered to solve mid- and large-scale problems. To confirm their accuracy of performance, two small-scale problems are solved using GAMS exact (...) solution software, and the obtained results have been compared with the output of the algorithms. Since the problem in this study is multiobjective, five comparative indices are used to compare the performance of algorithms. The results show that the answers achieved using the metaheuristic algorithms are very close to the ones achieved via the GAMS exact program. Therefore, the proposed algorithms are validated, and it is proved that they are accurately designed and useable in solving the real-world problems in logical calculation time. By comparing the obtained results, it can be seen that the MOEA/D algorithm performs better in terms of computational time and Mean ideal distance. The MOSA algorithm also performs better according to the index Spread of nondominated solutions, diversity metric, and number of Pareto solutions. Considering the confirmation of precision and accuracy of performance of the proposed algorithms, it can be concluded that MOSA and MOEA/D are useful in solving the mid- and large-scale modes of the problem in the study, which is very applicable in the real world.

Our purpose in this paper is to argue how the idea of affirmation of life embodies the practice of the art of life. The yes-saying attitude towards life can provide an enormous support for the self-formation practices. Our attempt, then, consists of demonstrating the subjective character of the aesthetic marked by pleasure, and especially a new approach to the relationship between “I” and the other. We comprehend that this sort of life is individually relative or subjective. Meanwhile, there is a (...) political reconfiguration of “I” and the other which ends in freedom. Politics becomes possible in a simultaneous caring for I and the other through the practices of self-constitution. In order to clarify our discussion further, this challenge is accompanied by a presentation of three real lives that are exemplary for us in the art of life; a way of being that stands for a political affirmation of life.

In The Joy of Science, Jim Al-Khalili presents eight lessons that serve as a guide to thinking and living life a little more scientifically. It is a gentle entrée to the conceptual core of what science is and the spirit of how it is practiced, which will help any reader understand how to live a more rational life and benefit from doing so. The book will connect the lay public with what science fundamentally is - not knowledge per se, (...) but rather a way of thinking, which gives us the power to turn encounters with the unknown into greater insights into the true nature of reality. In an engaging, conversational tone, and writing from the perspective of a practitioner of science, Al- Khalili invites readers to engage with the world in a new way and to think as scientists are trained to do about unsolved mysteries; the nature of truth, uncertainty, and the role of doubt; the value and dangers of simplification; the challenges of complexity or too little information; the importance of evidence-based thinking; the value of guarding against bias (in oneself and others); the importance of being able to change one's mind, and more. By the end, the reader will come away with a clear sense of how the ideas at the heart of the scientific method are deeply relevant to our current times, lives, and personal decision making. Knowing how to think and live more scientifically can make our all of our lives better, and this short book gives non-specialists a welcoming introduction to this knowledge, sharing "the joy" that science can bring.

This paper explores the general characteristics of the aesthetics of life. Our approach will be in thinking about the aesthetics of life as a domain independent from the realms of ethics and morality. This thesis discusses some of the theoretical debates around those concepts. The notion of ‘pleasure’ in those practices will be discussed as the one that gives shape to ‘the art of life’. Pleasure also makes it possible for a person to perform these practices for a long period (...) of time; what we call the ‘life-long character of the aestheticization of life’.However, this effort endeavors to demonstrate another central theme of this style of life; the individual/social character of those practices is the one that exemplifies ‘the art of life’. Thinking simultaneously about ‘oneself’ and the ‘other’ is the main concept that helps us the most to appreciate these practices. These debates are elaborated further in some case studies that have been researched between 2016 and 2019. These are real examples of peoples’ lived experiences who, in different ways, try to give meaning to their lives by turning their existence into a work of art. (shrink)

La recherche actuelle cherche à démontrer qu'il existe une sociologie chez Foucault et l'oeuvre foucaldienne est aussi une oeuvre sociologique. L'oeuvre de Foucault offre plusieurs avantages conceptuels à la pensée sociologique et sa pensée peut être entendue comme une expérience qui nous conduira aussi à une pratique autoréflexive de la sociologie. Mais ce qui rapproche le plus Foucault des sociologues, c'est toujours sa tentative de comprendre le sujet à travers un social qui est devenu historique et cette Histoire nous revient (...) à chaque fois en tant que forme culturelle. La question centrale de Foucault est ce social qui occupe une place considérable dans la constitution de l'individu, pourtant l'individu n'est jamais complètement contraint. Les grandes lignes de la pensée foucaldienne consistent à élaborer une pensée critique, une pensée qui est parvenue finalement à réunir l'objectivation et la subjectivation. La sociologie foucaldienne a pour objectif de mettre en lumière la question "qui sommes-nous en train de devenir?" pour construire un diagnostic sociologique d'une modernité paradoxale. (shrink)

Abstractabstract:Besila is a paradisical setting in the Kushnameh, an early twelfth-century Persian epic that combines the ancient Iranian messianic legend of Kangdez with more recent geographical knowledge, based on travelers' reports, of China and Korea. Besila’s messianic role in the narrative, its antipodal location, and its quasi-fictional status are quintessentially utopian, and yet little is revealed about the society of Besila. The Kushnameh instead emphasizes the means by which paradises are formed, including the rational origins of Besila’s monotheistic creed, organic (...) growth, translatio imperii, travel, and geographical knowledge. The Kushnameh’s vision of universal monotheism anticipates the story of Hayy ibn Yaqzan, a later utopia with important connections to the development of Islamic political theory. The case of Besila thus suggests that the early modern genre of utopia has deep roots in the medieval discourse of travel and travelers. (shrink)

This paper aims, first, to argue against using opaque AI technologies in decision making processes, and second to suggest that we need to possess a qualitative form of understanding about them. It first argues that opaque artificially intelligent technologies are suitable for users who remain indifferent to the understanding of decisions made by means of these technologies. According to virtue ethics, this implies that these technologies are not well-suited for those who care about realizing their moral capacity. The paper then (...) draws on discussions on scientific understanding to suggest that an AI technology becomes understandable to its users when they are provided with a qualitative account of the consequences of using it. As a result, explainable AI methods can render an AI technology understandable to its users by presenting the qualitative implications of employing the technology for their lives. (shrink)

This chapter explores the relevance of empirical evidence to real causes. I argue for the claim that instrumentally mediated empirical results are causally dependent on unobservable entities. I develop this idea in the context of discussions on entity realism. As a consequence of my argument, an antirealist version of empiricism, which underlines the significance of empirical evidence but which abstains from real causation, is incoherent.

Relying on the notion of “overlapping perspectives,” this paper argues that entity realism and perspectivism are complementary. According to entity realism, it is justified to maintain a positive attitude toward the existence of unobservable entities with which multiple experimental interactions are possible. Perspectivism also explains that our beliefs about these entities are bounded by historically contingent theoretical and instrumental perspectives. The argument of the paper is developed through a discussion of Ronald Giere’s versions of realism: entity realism, constructive realism, and (...) perspectival realism. (shrink)

Quantum physicist, New York Times bestselling author, and BBC host Jim Al-Khalili reveals how 8 lessons from the heart of science can help you get the most out of life Today’s world is unpredictable and full of contradictions, and navigating its complexities while trying to make the best decisions is far from easy. The Joy of Science presents 8 short lessons on how to unlock the clarity, empowerment, and joy of thinking and living a little more scientifically. In this (...) brief guide to leading a more rational life, acclaimed physicist Jim Al-Khalili invites readers to engage with the world as scientists have been trained to do. The scientific method has served humankind well in its quest to see things as they really are, and underpinning the scientific method are core principles that can help us all navigate modern life more confidently. Discussing the nature of truth and uncertainty, the role of doubt, the pros and cons of simplification, the value of guarding against bias, the importance of evidence-based thinking, and more, Al-Khalili shows how the powerful ideas at the heart of the scientific method are deeply relevant to the complicated times we live in and the difficult choices we make.

This paper concerns the recent revival of entity realism. Having been started with the work of Ian Hacking, Nancy Cartwright and Ronald Giere, the project of entity realism has recently been developed by Matthias Egg, Markus Eronen, and Bence Nanay. The paper opens a dialogue among these recent views on entity realism and integrates them into a more advanced view. The result is an epistemological criterion for reality: the property-tokens of a certain type may be taken as real insofar as (...) only they can be materially inferred from the evidence obtained in a variety of independent ways of detection.

The nature of state governance in consolidated liberal democracies has important implications for the ideal theory debate. The states of these societies are polycentric. Decision-making power within them is disaggregated across multiple sites. This rules out one major justification for ideal theory. On this influential view, the ideal furnishes a blueprint of the morally perfect society that we should strive to realise. This justification is not viable in consolidated liberal democracies because their states lack an Archimedean point from which the (...) institutional structure as a whole can be designed to accord with the true ideal – whichever it might be. However, knowledge of the ideal can still aid agents in those societies to determine the worth of more modest political objectives other than the ideal itself. (shrink)

It is widely accepted among political philosophers that distributive justice should be promoted by the state. This essay challenges this presumption by making two key claims. First, the state is not the only possible mechanism for attaining distributive justice. We could rely alternatively on the voluntary efforts and interactions of individuals and associations in civil society. The question of what mechanism we should rely on is a comparative and empirical one. What matters is which mechanism better promotes distributive justice. We (...) cannot settle the question a priori in favor of the state. Second, several considerations suggest a presumption in favor of relying on civil society. (shrink)

This paper draws on the phenomenological-hermeneutical approaches to philosophy of science to develop realist perspectivism, an integration of experimental realism and perspectivism. Specifically, the paper employs the distinction between “manifestation” and “phenomenon” and it advances the view that the evidence of a real entity is “explorable” in order to argue that instrumentally-mediated robust evidence indicates real entities. Furthermore, it underpins the phenomenological notion of the horizonal nature of scientific observation with perspectivism, so accounting for scientific pluralism even in the cases (...) of inconsistent models. Overall, realist perspectivism is proposed as the way to go for (phenomenologically-hermeneutically minded) philosophers of science. (shrink)

Auf den ersten Seiten der Philosophie des Rechts stellt Hegel fest, dass das, was zuvor in der Wissenschaft der Logik dargelegt wurde, hier nun vorausgesetzt wird. Der vorliegende Beitrag erläutert, was diese Voraussetzung bedeutet. Um das zu untersuchen, ist der Fokus auf einen bestimmten Begriff, nämlich den der Totalität gelegt. Es wird argumentiert, dass die Entwicklung in den verschiedenen Momenten der Philosophie des Rechts nicht möglich wäre ohne die vorausgehende Entwicklung der Metakategorie der Totalität in der Wissenschaft der Logik. Obwohl (...) es zu jedem dieser beiden Bücher eine Vielzahl von Veröffentlichungen gibt, fehlt in diesen wissenschaftlichen Arbeiten über Hegel eine Ausarbeitung gerade dieser Voraussetzung, nämlich insbesondere die Rolle, welche die Totalität in der Darstellung der Rechtsphilosophie im Verhältnis zu der Darstellung in der Wissenschaft der Logik spielt. Nachdem ein allgemeiner Überblick über jedes dieser Bücher gegeben wurde, wird in diesem Aufsatz eine solche Beziehung in fünf spezifischen Momenten der Rechtsphilosophie nachgezeichnet, nämlich: Wille, Moral, ethisches Leben, bürgerliche Gesellschaft und Staat.

Georg Wilhelm Friedrich Hegel (1770-1831) est probablement l’un des plus importants penseurs et philosophes de notre époque. On peut dire que les sciences humaines en général et la philosophie en particulier doivent prendre une position positive ou négative concernant la philosophie hégélienne avant de procéder à d’autres développements qui leur seraient propres. Plus précisément, ce collectif trouve sa racine dans une double urgence : les menaces des crises environnementale, politique et économique, les nouveaux enjeux qu’elles entraînent, d’une part, et l’absence (...) jusqu’à présent de réponses prometteuses, de l’autre. Il est temps de faire le point et de contribuer à fournir de nouvelles pistes de réflexion. Le présent ouvrage, bilingue, est le fruit de la collaboration d’éminents spécialistes internationaux qui ont répondu avec enthousiasme à notre invitation. Les 14 textes qui y sont réunis sont distribués selon trois thématiques et, tout en respectant la nature de la pensée hégélienne, leurs thèmes se chevauchent inévitablement. La première partie, « Aspects de la pensée de Hegel / Aspects of Hegel’s Thought », regroupe les textes qui discutent en profondeur d’un aspect de la pensée de Hegel, tout en analysant un enjeu qui se trouve dans ses propres œuvres. Les contributions de la deuxième partie, « Marx et Hegel / Marx and Hegel », examinent la relation entre ces deux philosophes. Comment faut-il comprendre les passages dans lesquels Marx accuse Hegel d’idéalisme, dont celui, largement cité, dans la préface du premier tome du Capital, n’est qu’un exemple? Dans la troisième partie, « Hegel à l’époque contemporaine / Hegel in Modern Times », les auteurs se penchent sur l’influence de la pensée de Hegel sur plusieurs penseurs. (shrink)

Although it is one of the indispensable standards of relevant research that Heidegger shortly after Being and Time made a „turn“ („Kehre“) in the development of his thinking, it can be shown that this is merely due to a misunderstanding or misinterpretation that began in 1949/50 with an at least incorrect reading of the corresponding passage in the Letter of Humanism. But if this legend of research can be proven as such, the question arises as to what consequences this will (...) have for the comprehension of Heidegger’s thinking, for it is said that with the „turn“, the transcendental approach was given up in favor of an aletheiological one with which it was possible for Heidegger to overcome subjectivism. In rejection of this by now equally canonical interpretation scheme it is shown here that the aletheiological approach is merely a recourse to conceptions important to Heidegger even before Being and Time and that after the failure of its third section – Time and Being – subjectivistic features were rather transferred, partially into a being that was increasingly thought of as an active one, partially into concepts like that of the „first thinker“ („erster Denker“) or the „messenger of being“ („Botenganger des Seins“). All in all, it is argued that the paradigm of „Heidegger‘ s turn“ should be abandoned in order to enable an unobstructed view on Heidegger’s thinking. (shrink)

As a leading scientist of the 13th century C. E. Quṭb al-Dīn Shīrāzī wrote three substantial works on hay'a (or the configuration of the celestial orbs): Nihāyat al-idrāk fī dirāyat al-aflāk ("The Limits of Attainment in the Understanding of the Heavens"), al-Tuḥfa al-shāhīya fī 'ilm al-hay'a ("The Royal Offering Regarding the Knowledge of the Configuration of the Heavens"), and Ikhtīyārāt-i Muẓaffarī ("The Muẓaffarī Elections"). Completed in less than four years and written in two of the classical languages of the Islamic (...) world, Arabic and Persian, these works provide a fascinating window to the astronomical research carried out in Ilkhanid Persia. Shīrāzī and his colleagues were driven by their desire to rid Ptolemaic astronomy from its perceived shortcomings. An intriguing trail of revisions and emendations in Shīrāzī's hay'a texts serves to highlight both those features of Shīrāzī's astronomy that were inherited from his predecessors, as well as his original contributions to this branch of astronomical research. As a renowned savant, Shīrāzī spent a large portion of his career near centers of political power in Persia and Anatolia. A study of his scientific output and career as a scholar is an opportunity, therefore, for an examination of the patronage of science and of scientific works within the Ilkhanid realms. Not only was this patronage important to the work of scholars such as Shīrāzī but it was critical to the founding and operation of one of the foremost scientific institutions of the medieval Islamic world, the Marāgha observatory. The astronomical tradition in which Shīrāzī carried out his research has many links, as well, to the astronomy of Early Modern Europe, as can be seen in the astronomical models of Copernicus.

Philosophy's “linguistic turn” was destined to find its way into derivative disciplines such as political theory. In the last two decades, this turn has led to an absurd reductionism extrapolating the essence of existing democracies from their mode of communication.

The central notion here is “deliberative democracy.” But is this a distinct model of democracy? For (...)

Introduction Talking about civilization is like talking about God. While the aim is to gain knowledge, often the result is only greater obscurity. What is at issue may not be really a concept, but nothing at all. Yet, concepts have their own history, and the UN's inauguration of 2001 as the year of the “dialogue of civilizations,” not to mention recent ethno-religious conflicts, has generated new interest in “civilizational” questions—despite the fact that this runs counter to the postmodern aversion to (...) traditional historiography, in favor of “micro-histories,”1 and objections to the term “civilization” on the ground that it cannot be defined….

The special theory of relativity holds significant interest for scientific perspectivists. In this paper, I distinguish between two related meanings of “perspectival,” and argue that reference frames are perspectives, provided that perspectival means “being conditional” rather than “being partial.” Frame-dependent properties such as length, time duration, and simultaneity, are not partially measured in a reference frame, but their measurements are conditional on the choice of frame. I also discuss whether the constancy of the speed of light depends on perspectival factors (...) such as the idealized definition of the speed of light in a perfect vacuum and the Einstein synchronization convention. Furthermore, I argue for the view that the constancy of its speed is a robust property of light according to the conditions of currently acceptable experimental setups pertaining to special relativity, and conclude that this view supports perspectivism.

This paper proposes a way to understand the meaning of reality (in science) on the basis of the concepts of persistence and resistance. It first supports the ontological view that reality consists of persistent potentialities, which resist being excluded from existence. A study of the cases of the Higgs boson and the hypothetical Ϝ-particle helps to illustrate how real entities persist and resist. The paper then suggests that, perceptually speaking, the results of ordinary perception or observational processes persistently appear under (...) appropriate conditions, and they resist disappearance even when the appropriate conditions are not completely prepared. Finally, it argues that, epistemologically speaking, a truthful theory resists being falsified and persists across replicable observations and experiments. (shrink)

This dissertation is about human knowledge of reality. In particular, it argues that scientific knowledge is bounded by historically available instruments and theories; nevertheless, the use of several independent instruments and theories can provide access to the persistent potentialities of reality. The replicability of scientific observations and experiments allows us to obtain explorable evidence of robust entities and properties. The dissertation includes seven chapters. It also studies three cases – namely, Higgs bosons and hypothetical Ϝ-particles (section 2.4), the Ptolemaic and (...) Kepler model of the planets (section 6.7), and the special theory of relativity (chapter 7). -/- Chapter 1 is the introduction of the dissertation. Chapter 2 clarifies the notion of the real on the basis of two concepts: persistence and resistance. These concepts enable me to explain my ontological belief in the real potentialities of human-independent things and the implications of this view for the perceptual and epistemological levels of discussion. On the basis of the concept of “overlapping perspectives”, chapter 3 argues that entity realism and perspectivism are complementary. That is, an entity that manifests itself through several experimental/observational methods is something real, but our knowledge of its nature is perspectival. Critically studying the recent views of entity realism, chapter 4 extends the discussion of entity realism and provides a criterion for the reality of property tokens. Chapter 5, in contrast, develops the perspectival aspects of my view on the basis of the phenomenological-hermeneutical approaches to the philosophy of science. This chapter also elaborates my view of empirical evidence, as briefly expressed in sections 2.5 and 4.5. Chapter 6 concerns diachronic theoretical perspectives. It first explains my view of progress, according to which current perspectives are broader than past ones. Second, it argues that the successful explanations and predictions of abandoned theories can be accounted for from our currently acceptable perspectives. The case study of Ptolemaic astronomy supports the argument of this chapter. Chapter 7 serves as the conclusion of the dissertation by applying the central themes of the previous chapters to the case study of special relativity theory. I interpret frame-dependent properties, such as length and time duration, and the constancy of the speed of light according to realist perspectivism. (shrink)

The central motivation behind the scientific realism debate is explaining the impressive success of scientific theories. The debate has been dominated by two rival types of explanations: the first relies on some sort of static, referentially transparent relationship between the theory and the unobservable world, such as truthlikeness, representation, or structural similarity; the second relies on no robust relationship between the theory and unobservable reality at all, and instead draws on predictive similarity and the stringent methodology of science to explain (...) success. I argue that this is a false dichotomy, at least insofar as dynamical theories are concerned. The best explanation of the success of dynamical theories, I argue, must appeal to a robust but referentially opaque theory–world relation. The dynamical notion of ‘tracking’ fulfills this promise. I formulate a modified no miracles argument that is liberated from the false dichotomy and show how tracking responds to the modified argument. (shrink)

Virtually all philosophers of science have construed fundamental theories as descriptions of entities, properties, and/or structures. Call this the “descriptive-ontological” view. I argue that this view is incorrect, at least insofar as physical theories are concerned. I propose a novel construal of theories that I call the “prescriptive-dynamical” view. The central tenet of this view, roughly put, is that the _essential_ content of fundamental physical theories is a _prescription for interfacing with natural systems and translating local data into compact theoretical (...) language_. The descriptive-ontological aspects of theories, if any, are taken as _inessential_ content on this view: they do not contribute to the predictive success of the theory. Rather than describing _what is there_, the essence of a physical theory is to tell us _what to do_ when interfacing with a physical system. (shrink)

The main thesis of the dissertation is that Hume resolves his central concern with the problem of reason by arguing for a pragmatic conception of that notion. After a discussion of Hume's argument to the effect that the traditional conception of reason leads to unmitigated scepticism, I turn to Hume's account of belief. Vivacity is the distinguishing mark of a belief. That notion has two aspects: an intrinsic felt quality, and a causal connection to action. The former is part of (...) the descriptive account of belief and the latter accounts for the normative distinctions among beliefs. A belief is rationally warranted, if it leads to beneficial consequences. Both the descriptive-explanatory and the normative-evaluative accounts of belief rest on Hume's conception of the imagination. In the last chapter, it is argued that Malebranche significantly influenced Hume's conception of the imagination. (shrink)

The Correspondence Principle of old quantum theory is commonly considered to be the requirement that quantum and classical theories converge in their empirical predictions in the appropriate asymptotic limit. That perception has persisted despite the fact that Bohr and other early proponents of CP clearly did not intend it as a mere requirement, and despite much recent historical work. In this paper, I build on this work by first giving an explicit formulation to the mentioned asymptotic requirement ) and then (...) discussing various possible formulations of CP for emission on the basis of the primary literature as well as general physical and metaphysical considerations. I shall then show that, in all of the most probable interpretations of CP that consider quantum theory as a universal theory, any system incorporating both CR and CP for emission would in fact be inconsistent. Old quantum theory measurably contradicts classical physics in the classical regime. (shrink)

In this paper, we introduce a foundation for computable model theory of rational Pavelka logic and continuous logic, and prove effective versions of some related theorems in model theory. We show how to reduce continuous logic to rational Pavelka logic. We also define notions of computability and decidability of a model for logics with computable, but uncountable, set of truth values; we show that provability degree of a formula with respect to a linear theory is computable, and use this to (...) carry out an effective Henkin construction. Therefore, for any effectively given consistent linear theory in continuous logic, we effectively produce its decidable model. This is the best possible, since we show that the computable model theory of continuous logic is an extension of computable model theory of classical logic. We conclude with noting that the unique separable model of a separably categorical and computably axiomatizable theory is decidable. (shrink)

We present a review of part of the results obtained by the authors for the statistics of coherent radiation propagating in a random medium both in the framework of diagrammatic techniques and random matrix theory.

According to the care crisis in modern medicine, the existential needs of patients are not sufficiently satisfied. One idea is that to address the crisis physicians should be educated to be virtuous. This suggestion is helpful but incomplete. It does not take into account the part of (non-)human factors, including (medical) technologies. In particular, the paper focuses on online caring forums and argues that they are technological factors that can play the role of focal things, in which the members gather (...) together to do a care-related focal practice. Furthermore, we empirically study the online forums of Ninisite, a popular Persian website on pregnancy, childbirth, and parenting, and suggest that these forums shape focal practices that are helpful in alleviating the care crisis.
