Aristotle's notion of evil is highly elaborate and attractive, yet has been largely overlooked by philosophers. While most recent studies of evil focus on modern understandings of the concept, this volume shows that Aristotle's theory is an invaluable resource for our contemporary understanding of it. Twelve leading scholars reconstruct the account of evil latent in Aristotle's metaphysics, biology, psychology, ethics, and politics, and detect Aristotelian patterns of thought that operate at certain landmark moments in the history of philosophy from ancient (...) thought to modern day debates. The book pays particular attention to Aristotle's understanding of 'radical evil', an important and much disputed topic. Original and systematic, this study is the first to provide a full exploration of evil in Aristotle's work, shedding light on its content, potential, and influence. The volume will appeal to scholars of ancient Greek philosophy as well as to moral philosophers and to historians of philosophy. (shrink)

The problem of intertemporal choice arises when outcomes are received in different moments of time. This paper presents an axiomatic model of intertemporal choice when consumption in the previous moment of time contributes to utility evaluation of consumption in the current moment. This model generalizes classic discounted utility theory (also known as constant or exponential discounting) in two ways. First, in every moment of time, a decision maker derives utility not only from current consumption but also from “residual” consumption in (...) the previous moment of time. Second, these utilities are discounted with weights that are essentially a quasi-hyperbolic discounting function. The paper presents an application of the proposed model to the problem of optimal consumption and savings given a fixed income (wealth). When a decision maker derives satisfaction from both instantaneous consumption as well as a share of consumption in the previous moment of time, optimal consumption path is cyclic—periods of relatively high consumption are interchanged with periods of relatively low consumption. These cycles decay over time. Asymptotically, the consumption path exhibits conventional properties (constant, increasing or decreasing over time when a gross interest rate multiplied by discount factor is correspondingly equal to, greater than, or less than one).

In a recent article, Zhang and Foo generalized the AGM postulates for contraction to include infinite epistemic input. The new type of belief change is called set contraction. Zhang and Foo also introduced a constructive model for set contraction, called nicely ordered partition, as a generalization of epistemic entrenchment. It was shown however that the functions induced from nicely ordered partitions do not quite match the postulates for set contraction. The mismatch was fixed with the introduction of an extra condition (...) called the limit postulate. The limit postulate establishes a connection between contraction by infinite epistemic input and contraction by finite epistemic input (reducing the former to the latter) and it is appealing both on mathematical and on conceptual grounds. It is debatable however whether the limit postulate can be adopted as a general feature of rationality in set contraction. Instead we propose that the limit postulate is viewed as a condition characterizing an important special case of set contraction functions. With this reading in mind, in this article we introduce an alternative generalization of epistemic entrenchment, based on the notion of comparative possibility. We prove that the functions induced from comparative possibility preorders precisely match those satisfying the postulates for set contraction (without the limit postulate). The relationship between comparative possibility and epistemic entrenchment is also investigated. Finally, we formulate necessary and sufficient conditions under which the functions induced from comparative possibility preorders coincide with the special class of contraction functions characterized by the limit postulate.

On December 5, 1963, at the end of the second session of the Second Vatican Council, a "Decree on means of public notice" was signed together with the Constitution on the Holy Liturgy. This was the first of the nine decrees issued by the Council, which expressed the views of the entire Ecumenical Church, which represented at the Council more than 2500 bishops, experts and theologians who participated in the General Assembly. Almost half of the Fathers of the Council were (...) pastors of European dioceses. There were also 379 African bishops, 300 bishops from Asia and almost a thousand from the United States at the Council. All of them - the heirs of the College of the Apostles - saw humanity entering into a new phase of dialogue through the media, and wanted to answer the question of whether the Church could use them for their development and proclamation of the Gospel.

Below, suggested thoughts were expressed by me when I just learned about an irreparable event - the departure from the earthly existence of pastor Peter Konstantinovich Martyanov. Since then, it's hard to imagine now, two years. Time spell is inexorable. But there is a higher flow of time. It is human honor and memory. The good deeds of man live uncountably for a long time as an embodiment of the memory of her. And a man lives as much as he (...) will remember about his good deeds. So - everyone chooses in his earthly existence his own way. The Path of eternal Remembrance of your own good deeds, or the unlucky darkness of your own evil deeds. Peter Konstantinovich always served God, and hence - people. Therefore, he will be remembered with respect and remembered by a good word and after leaving the earthly life. Therefore, on the deadline of September 7, the religious scholars of Ukraine, with whom he worked fruitfully to establish tolerance in interfaith relations in the Odessa region, was to be honored, to honor the light of the memory of the man who did so much for the establishment of Ukrainian unbiased religious studies, who was not afraid to be righteous and sincere then When it was not easy, who was not afraid, as Vasyl Stus once articulated, to be "self-fulfilling".

How is it possible that the idea of sovereignty still features in legal and political philosophy? Most contemporary political philosophers have little use for the idea of ‘unlimited’ or ‘absolute’ power, which is how sovereignty is normally defined. A closer look at sovereignty identifies two possible accounts: sovereignty as the fact of power or sovereignty as a title to govern. The first option, which was pursued by John Austin’s command theory of law, leads to an unfamiliar view of law and (...) the state, which was justly criticised by H. L. A. Hart. The second option, leads to a paradox, because under this view sovereignty is both limited and unlimited. Hence, this argument shows that law and sovereignty are actually incompatible. Where there is law there is no sovereignty, and where there is sovereignty there is no law. (shrink)

This book offers a new account of Aristotle's practical philosophy. Pavlos Kontos argues that Aristotle does not restrict practical reason to its action-guiding and motivational role; rather, practical reason remains practical in the full sense of the term even when its exercise does not immediately concern the guidance of our present actions. To elucidate why this wider scope of practical reason is important, Kontos brings into the foreground five protagonists that have long been overlooked: spectators or judges who make (...) non-motivational judgments about practical matters that do not interact with their present deliberations and actions; legislators who exercise practical reason to establish constitutions and laws; hopes as an active engagement with moral luck and its impact on our individual lives; prayers as legislators' way to deal with the moral luck hovering around the birth of constitutions and the prospect of a utopia; and people who are outsiders or marginal cases of the responsibility community because they are totally deprived of practical reason. Building on a wide range of interpretations of Aristotle's practical philosophy, Kontos offers new insights about Aristotle's philosophical contribution to the current debates about radical evil, moral luck, hope, utopia, internalism and externalism, and the philosophy of law. Aristotle on the Scope of Practical Reason will appeal to researchers and advanced students interested in Aristotle's ethics, ancient philosophy, and the history of practical philosophy. (shrink)

Interest in corporate social responsibility (CSR) is gaining momentum in academic and managerial circles. However, prior work in the area has paid little attention to how CSR initiatives should be implemented inside the organization. Against this backdrop, this study examines the impact of CSR initiatives on an important stakeholder group—employees. We build and test a comprehensive multilevel framework that focuses on whether employees derive job satisfaction from CSR programs. The proposed model predicts that a manager’s charismatic leadership influences employees’ interpretations (...) about the motives underlying their companies’ engagement in CSR initiatives (intrinsic and extrinsic CSR-induced attributions) which, in turn, influence employee job satisfaction. Hierarchical linear modeling of data from 47 organizational units comprising 438 employees from three world-leading manufacturing organizations shows that when employees think that their manager possesses charismatic leadership qualities, they tend to attribute the organization’s motives for engaging in CSR activities to intrinsic values, which, in turn, are positively associated with job satisfaction. Also, the extent to which managers are perceived as charismatic leaders relates positively to job satisfaction. Interestingly, CSR-induced extrinsic attributions are neither explained by charismatic leadership nor do they predict job satisfaction. Implications for both theory and practice are discussed.

Alchourrón, Gärdenfors and Makinson have developed and investigated a set of rationality postulates which appear to capture much of what is required of any rational system of theory revision. This set of postulates describes a class of revision functions, however it does not provide a constructive way of defining such a function. There are two principal constructions of revision functions, namely an epistemic entrenchment and a system of spheres. We refer to their approach as the AGM paradigm. We provide a (...) new constructive modeling for a revision function based on a nice preorder on models, and furthermore we give explicit conditions under which a nice preorder on models, an epistemic entrenchment, and a system of spheres yield the same revision function. Moreover, we provide an identity which captures the relationship between revision functions and update operators (as defined by Katsuno and Mendelzon). (shrink)

Many political and legal philosophers compare the EU to a federal union and believe its basic laws should be subject to the standards of constitutional law, and thus find it lacking or incomplete. This book proposes a rival theory: that the substance of EU law is not constitutional, but international, and provides a close examination of the treaties and the precedents of the European courts to explore this concept further. -/- Just like international law, EU law applies primarily to the (...) relations between member states, who have democratically chosen to adapt their constitutional arrangements in order to share legislative and executive powers with their partners. The legal architecture of the European Union is thus best understood under a theory of dualism and not pluralism. -/- According to this 'internationalist' view, EU law is part of the law of nations and its distinction from domestic law is a matter of substance, not form. This arrangement is supported by a cosmopolitan theory of international justice, which we may call progressive internationalism. The EU is a union of democratic peoples, freely organizing their interdependence on the basis of principles of equality and reciprocity. Its central principles are not the principles of a constitution, but cosmopolitan principles of accountability, liberty, and fairness. -/- Presenting an 'internationalist' reading, this book proposes that the EU is a creation of the law of nations, and argues for a dualist account of its legal architecture, with EU law and domestic law allocated different institutional roles.

One of the theoretical developments associated with the law of the European Union has been the flourishing of legal and constitutional theories that extol the virtues of pluralism. Pluralism in constitutional theory is offered in particular as a novel argument for the denial of unity within a framework of constitutional government. This paper argues that pluralism fails to respect the value of integrity. It also shows that at least one pluralist theory seeks to overcome the incoherence of pluralism by implicitly (...) endorsing monism. The integrity and coherence of European law is best preserved by considering that both the national legal order and the international or European legal orders adopt sophisticated views of their own limits.

It is in particular a question of the mezzanine and of the shop-front, which often includes a large bay and a second door accessing (...) a staircase leading to the upper storey. These elements are found in other rooms of this type at Delos, constituting one of the criteria for their identification, and enable a better understanding of their function. (shrink)

This paper presents a new decision theory for modelling choice under risk. The new theory is a two-parameter generalization of expected utility theory. The proposed theory assumes that a decision maker: behaves as if maximizing expected utility; but may experience disappointment when the utility of a lottery’s outcome falls short of the expected utility of the lottery; and may have a preference for gambling. The proposed theory can rationalize the fourfold pattern of risk attitudes; the common ratio effect and the (...) reverse thereof ; the Allais paradox in classical common consequence problems and the reverse Allais paradox—in common consequence problems with an even split of a probability mass; violations of the betweenness axiom; switching behavior in the Samuelson’s example; violations of ordinal, upper and lower cumulative independence ; and preference reversals between valuations and choice. In application to insurance, the theory can rationalize full insurance with an actuarially unfair premium and aversion to probabilistic insurance. In application to optimal portfolio investment, the theory can rationalize the equity premium puzzle. (shrink)

This book provides a balanced and accessible introduction to Aristotle's Nicomachean Ethics. It carefully and comprehensively follows the thread of Aristotle’s argument and sheds light on topics that all too often receive little attention or are entirely ignored in the existing textbooks (such as self-control, legislative science and the legislator, the life of the money-maker, craft-knowledge, comprehension, and beastliness). Its objective is not only to offer an academically reliable presentation of Aristotle’s Ethics but to also defend Aristotle’s main tenets—or, at (...) least, to present them in their most defensible form. It places the Nicomachean Ethics within the study of ethics generally; students are invited to understand Aristotle’s claims in the light of, or in contrast to, other ethical theories or their own intuitions about ethical matters. It follows the reader of the Nicomachean Ethics in action, registering questions, expectations and progress within an insightful exegesis of Aristotle's philosophical argument. It is replete with pedagogical tools including examples from our concrete everyday experience, paintings, films, and literature, end of chapter summaries, internet resources, suggestions for further reading, study questions, and essay questions.

The theme of the emergence of Christianity has always been and remains the problem, around which there continually undergo scientific discussions, due to the desire to recreate the origins of the historical birth of Christianity, to understand what served him as a kind of informational basis. Religious literature never existed in a certain conceptual unity in the understanding of the sources of Christian religiosity. Somewhere they fluctuate in one direction or another, depending on the ideological position of the researcher and (...) his own attitude towards this religion. However, according to some distinguishing features, certain hypothetical points of view on the origin of Christianity are reduced to the characteristic two. The first one is the beginning of its emergence with Judaism, and considers Christianity to be a logical continuation and, so to speak, a successor, albeit largely different from him. The second - deduces the origin of Christianity from the sphere of Greek idealist thought as such, which served the generative cause of its foundation. (shrink)

The cornerstone of any religion is its anthropological concept, which seeks to determine the essential orientations of man, to outline the ideological framework of its existence, to represent the idea of ​​its essence, purpose in earthly life. The main task of the religious system is the act of involving and subordinating man to the spiritual divine realm as the realm of the transcendental existence of God. Belief in the real presence of the latter implies a new understanding of oneself, which (...) ultimately leads the religious individual to the desire to be involved in this transcendental existence, to have intimate relations with him, to have a consciousness inherent in God. Note that in this context, all human being is interpreted as a certain arena for this realization. Therefore, the religious life of the individual acquires the status of religious activity. (shrink)

In binary choice between discrete outcome lotteries, an individual may prefer lottery L1 to lottery L2 when the probability that L1 delivers a better outcome than L2 is higher than the probability that L2 delivers a better outcome than L1. Such a preference can be rationalized by three standard axioms (solvability, convexity and symmetry) and one less standard axiom (a fanning-in). A preference for the most probable winner can be represented by a skew-symmetric bilinear utility function. Such a utility function (...) has the structure of a regret theory when lottery outcomes are perceived as ordinal and the assumption of regret aversion is replaced with a preference for a win. The empirical evidence supporting the proposed system of axioms is discussed. (shrink)

Austin's theory of theory of law is simple: the law follows the pattern of power; the sovereign gives commands and obeys none; the subject obeys commands; the law consists in only those commands that directly or indirectly emanate from the sovereign. Nevertheless, Austin's theory of sovereignty is not simple at all. When we look at the relevant chapters closely, it becomes evident that Austin has two rival theories of sovereignty, one for a single person and one for a 'determinate body'. (...) It is only the latter that allows him to say that sovereignty lies, ultimately, with the electors, the strange conclusion of his book. But Austin's second theory of sovereignty is not consistent with his own theory of law. Austin's faces a dilemma. Is law - as most people take it to be - a public order of standards of conduct aiming to guide behaviour? If so, sovereignty ought to be public and intelligible. If not, sovereignty can remain a mystery to those living under it . For the latter reading, law and sovereignty are 'normatively inert,' as some of Austin's followers claim today. But Austin does not agree with his modern followers. Austin's second theory of sovereignty is aimed at satisfying a practical requirement of law and jurisprudence, i.e. to be in the position of publicly guiding conduct. (shrink)

Henri Bergsono gyvybės kilmės hipotezė vengia pateikti šios problemos sprendimą, visgi filosofas pateikia keletą pasiūlymų.

Nous posons à Aristote une question bien claire : en quoi consiste l'autonomie de la Raison pratique? Cette autonomie ne sera pas assuree par la Raison kantienne et sa prétention à l'universalité mais par une " perception morale " (aisthesis), par la phronésis. Notre entreprise fait avancer la question d'un pas supplémentaire. Elle prétend imprimer à la réponse aristotelicienne une orientation précise, étant donné qu'elle fait dépendre cette autonomie de la possibilite d'une ontologie (c'est-à-dire, d'une phénoménologie) de l'action morale. Notre (...) position peut donc s'annoncer ainsi : la phronésis, en tant qu'accès aux principes de la prakis, constitue la condition de possibilite de toute action morale. La fonction de la phronésis se trouvera éclairée à travers l'analyse du problème de l'altérité, de la reconnaissance de l'autre. Cet autre " en chair et en os ", nous le rechercherons dans l'ami aristotélicien. La structure de l'amitié sera déterminée dans son opposition par rapport aux modèles de la techné et de la Sophia, ce qui conduira finalement à l'autonomie de la sphère pratique. Si cette description de la praxis s'avère être effectivement en adéquation avec les phénomènes eux-mêmes, nous aurons ouvert une voie destinée à faire apparaitre une coïncidence de l'ontologie et de la morale, auquel cas l'ontologie de la praxis reflétera les principes du " bien agir " lui-même.

For decades, discrete choice modelling was practically dominated by only two models: multinomial probit and logit. This paper presents a novel alternative—harmonic choice model. It is qualitatively similar to multinomial probit and logit: if one choice alternative greatly exceeds all (falls below at least one of) other alternatives in terms of utility then it is chosen with probability close to one (zero). Compared to probit and logit, the new model has relatively flat tails and it is steeper in the neighborhood (...) of zero (when all alternatives yield the same utility and the decision maker chooses among them at random).

Prospect theory emerged as one of the leading descriptive decision theories that can rationalize a large body of behavioral regularities. The methods for eliciting prospect theory parameters, such as its value function and probability weighting, are invaluable tools in decision analysis. This paper presents a new simple method for eliciting prospect theory’s value function without any auxiliary/simplifying parametric assumptions. The method is applicable both to choice under ambiguity (Knightian uncertainty) and risk (when events are characterized by objective probabilities). Our new (...) elicitation method is implemented in a simple paper-and-pencil experiment (via an iterative multiple price list format). This is one of the first experiments that elicits non-parametric prospect theory’s value function with salient rewards. The collected data generally confirm findings in the existing literature: the value function is S-shaped (concave in the gain domain and convex in the loss domain) though there is a weaker loss aversion on the aggregate level and a substantial heterogeneity in loss aversion on the individual level (41% loss averse, 6% loss neutral and 53% gain seeking).

We find evidence of only a weak endowment effect when contestants exchange (...) their box for another box with the same distribution of possible prizes. (shrink)

Many political philosophers believe that we owe moral obligations to our political communities simply because we are asked. We are, for example to pay taxes, or serve in the army whenever we are demanded to do so by the competent authorities or agencies. Can such moral obligations be created by European Union institutions? This essay discusses the natural duty of justice to support just or nearly just political institutions as defended by John Rawls and Jeremy Waldron. It suggests that European (...) Union institutions can be seen to create similar obligations, only if we adopt a cosmopolitan theory of political legitimacy for both domestic and international institutions. A key distinction proposed is that between a duty of jurisdiction, owed by everyone to every legitimate state, and a duty of civility, owed by citizens to their own states. (shrink)

Aristotle tries to solve the riddle of future-directedness and luck-awareness by offering an account of what he calls ‘good hope’ or hoping-well. I concede that hope does not hold Aristotle’s attention for long.

The present paper proposes a new reading of one of the most obscure passages of De Architectura; in I, 1,3 Vitruvius claims that in architecture there is always a signifier and a signified, but his approach differs from Quintilian’s as presented in the latter’s Institutio Oratoria. Vitruvius’ is closer to Chrysippus approach, but he fails to mention the third constituent, the tynchanon. This omission is probably due to the fact that Vitruvius speaks of designs rather, than of existing buildings. What (...) can successfully signify a proposed building is, according to my reading, the design and erection of a building that is easily recognized by the public as realizing the intentions of the community to erect the proposed building. Such successful signification constitutes the ultimate criterion for good architecture. (shrink)

Despite the undeniable epistemic progress of developmental biology from the second half of the twentieth century to the present day, there still is widespread disagreement on defining the biological term of ‘development’. This scientific field epistemologically is neither unsuccessful nor immature, thus the persistent lack of agreement on its most central concept raises some important questions: is there any need for an explicit definition of biological development, and if so, what content should the definition have? My central thesis is twofold. (...) First, that current definitions of biological development are conceptually or empirically inadequate. Second, that an explicit definition of biological development is very much needed (a) for the practical purposes of science textbooks, but more importantly is needed (b) epistemically for exposing or overcoming problematic assumptions and for partially guiding scientific research by coding the appropriate assumptions. To support this thesis, initially I will show the deficiencies of the dominant definitions of biological development; and subsequently I will provide two arguments: an Argument from Practical Purposes and an Argument from Epistemic Purposes. Finally, for accommodating practical and epistemic purposes and as a response to the inadequacy of the available definitions of development, I will propose and defend an operational definition of biological development which is aimed to be broader than the received ones, while being more precise and fruitful to conduct empirical research.
