This paper presents a new model for pricing OTC derivatives subject to collateralization. It allows for collateral posting adhering to bankruptcy laws. As such, the model can back out the market price of a collateralized contract. This framework is very useful for valuing outstanding derivatives. Using a unique dataset, we find empirical evidence that credit risk alone is not overly important in determining credit-related spreads. Only accounting for both collateral arrangement and credit risk can sufficiently explain unsecured credit costs. This (...) finding suggests that failure to properly account for collateralization may result in significant mispricing of derivatives. We also empirically gauge the impact of collateral agreements on risk measurements. Our findings indicate that there are important interactions between market and credit risk. (shrink)

This paper attempts to assess the economic significance and implications of collateralization in different financial markets, which is essentially a matter of theoretical justification and empirical verification. We present a comprehensive theoretical framework that allows for collateralization adhering to bankruptcy laws. As such, the model can back out differences in asset prices due to collateralized counterparty risk. This framework is very useful for pricing outstanding defaultable financial contracts. By using a unique data set, we are able to achieve a clean (...) decomposition of prices into their credit risk factors. We find empirical evidence that counterparty risk is not overly important in credit-related spreads. Only the joint effects of collateralization and credit risk can sufficiently explain unsecured credit costs. This finding suggests that failure to properly account for collateralization may result in significant mispricing of financial contracts. We also analyze the difference between cleared and OTC markets. (shrink)

This paper presents an analytical model for valuing interest rate swaps, subject to bilateral counterparty credit risk. The counterparty defaults are modeled by the reduced-form model as the first jump of a time-inhomogeneous Poisson process. All quantities modeled are market-observable. The closed-form solution gives us a better understanding of the impact of the credit asymmetry on swap value, credit value adjustment, swap rate and swap spread.

The one-side defaultable financial derivatives valuation problems have been studied extensively, but the valuation of bilateral derivatives with asymmetric credit qualities is still lacking convincing mechanism. This paper presents an analytical model for valuing derivatives subject to default by both counterparties. The default-free interest rates are modeled by the Market Models, while the default time is modeled by the reduced-form model as the first jump of a time-inhomogeneous Poisson process. All quantities modeled are market-observable. The closed-form solution gives us a (...) better understanding of the impact of the credit asymmetry on swap value, credit value adjustment, swap rate and swap spread. (shrink)

This article presents a comprehensive framework for valuing financial instruments subject to credit risk. In particular, we focus on the impact of default dependence on asset pricing, as correlated default risk is one of the most pervasive threats in financial markets. We analyze how swap rates are affected by bilateral counterparty credit risk, and how CDS spreads depend on the trilateral credit risk of the buyer, seller, and reference entity in a contract. Moreover, we study the effect of collateralization (...) on valuation, since the majority of OTC derivatives are collateralized. The model shows that a fully collateralized swap is risk-free, whereas a fully collateralized CDS is not equivalent to a risk-free one. (shrink)

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces (...) naturally a non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

Triviality arguments against the computational theory of mind claim that computational implementation is trivial and thus does not serve as an adequate metaphysical basis for mental states. It is common to take computational implementation to consist in a mapping from physical states to abstract computational states. In this paper, I propose a novel constraint on the kinds of physical states that can implement computational states, which helps to specify what it is for two physical states to non-trivially implement the same (...) computational state.

Sydney Shoemaker argues that a certain class of self-ascriptions is immune to error through misidentification relative to the first-person pronouns. In their “Self-Consciousness and Immunity,” Timothy Lane and Caleb Liang question Shoemaker’s view. Lang and Liang present a clinical case and an experiment and argue that they are counterexamples to Shoemaker’s view. This paper is a response to Lane and Liang’s challenge. I identify the desiderata that a counterexample to Shoemaker’s view must meet and show that somatoparaphrenia and the Body (...) Swap Illusion fail to meet those desiderata. Thus, despite being puzzling phenomena, somatoparaphrenia and the Body Swap Illusion are not counterexamples to Shoemaker’s view. (shrink)

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of (...) QmbC, the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

In this paper, I show that Polleit and Mariano (2011) are right in concluding that Credit Default Swaps (CDS) are per se unobjectionable from Rothbard’s libertarian perspective on property rights and contract theory, but that they fail to derive this conclusion properly. I therefore outline the proper explanation. In addition, though Polleit and Mariano are correct in pointing out that speculation with CDS can conceivably hurt the borrowers’ interests, they fail to grasp that this can be the case only in (...) some peculiar circumstances that I identify. In other words, they miss the bigger picture, the one outside special circumstances, in which CDS trading has the opposite effect. That is, CDS facilitate debt accumulation, including government debt accumulation. Finally, I point out how this can precipitate the collapse of fiat money regimes. An incidental goal of the analysis is to provide a better account than Polleit and Mariano of recent government interventions in and around CDS markets. (shrink)

Since the transparency approach to introspection need not posit a dedicated mechanism specialized for detecting one’s own mental states, its economy is often viewed as a major advantage by both proponents and opponents. But sometimes economy comes at the cost of relying on controversial views of the natures of mental states. Perceptual experience is a case in point. For example, Alex Byrne’s account relies on the view that experience constitutively involves belief, and Matthew Boyle’s account relies on the view that (...) experience constitutively involves a form of implicit consciousness of experience. In this paper, I develop a transparency account of our access to our experiences that retains the benefit of economy while avoiding the cost of relying on controversial views of the nature of experience. I start by discussing Byrne’s and Boyle’s accounts. I focus on the problems that lead them to hold the controversial views they do, and raise some challenges to their solutions. I then develop my own account. I argue that when you attend to an object, your experience gives you justification to believe that you see the object (under some descriptions). I close by highlighting some advantages of my account. I argue that it (1) can solve the problems facing Byrne and Boyle without relying on controversial views of the nature of experience; (2) respects the idea that there is something special about our access to our minds; and (3) can be generalized to other cases of introspection.

The issue of climate change poses an important problem that requires immediate collaboration from everyone, including individuals, governments, and businesses. While consumption culture constitutes a significant proportion of greenhouse gas emissions, most of these emissions are caused by the consumption of the wealthiest. In this article, we will explore the challenges that consumer culture has exacerbated regarding climate change and propose that transitioning to a simpler and more sustainable lifestyle could be an effective solution in the fight against climate change. (...) Such transitions can be leveraged through the inspiration of celebrities (e.g., Keanu Reeves, Chow Yun-fat, Kristen Bell, Leonardo DiCaprio) that pursue simple, non-glamorous lifestyles that do not promote excessive consumerism.

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are (...) given. Specifically, a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

The extended mind hypothesis (EMH) is the claim that the mind can and does extend beyond the human body. Adams and Aizawa (A&A) contend that arguments for EMH commit a ‘coupling constitution fallacy’. We deny that the master argument for EMH commits such a fallacy. But we think that there is an important question lurking behind A&A's allegation: under what conditions is cognition spread across a tightly coupled system? Building on some suggestions from Haugeland, we contend that the system (...) must exhibit a distinctive sort of semantic activity, semantic activity that the system as a whole takes responsibility for.

Background Retraction is a mechanism for alerting readers to unreliable material and other problems in the published scientific and scholarly record. Retracted publications generally remain visible and searchable, but the intention of retraction is to mark them as “removed” from the citable record of scholarship. However, in practice, some retracted articles continue to be treated by researchers and the public as valid content as they are often unaware of the retraction. Research over the past decade has identified a number of (...) factors contributing to the unintentional spread of retracted research. The goal of the Reducing the Inadvertent Spread of Retracted Science: Shaping a Research and Implementation Agenda (RISRS) project was to develop an actionable agenda for reducing the inadvertent spread of retracted science. This included identifying how retraction status could be more thoroughly disseminated, and determining what actions are feasible and relevant for particular stakeholders who play a role in the distribution of knowledge. -/- Methods These recommendations were developed as part of a year-long process that included a scoping review of empirical literature and successive rounds of stakeholder consultation, culminating in a three-part online workshop that brought together a diverse body of 65 stakeholders in October–November 2020 to engage in collaborative problem solving and dialogue. Stakeholders held roles such as publishers, editors, researchers, librarians, standards developers, funding program officers, and technologists and worked for institutions such as universities, governmental agencies, funding organizations, publishing houses, libraries, standards organizations, and technology providers. Workshop discussions were seeded by materials derived from stakeholder interviews (N = 47) and short original discussion pieces contributed by stakeholders. The online workshop resulted in a set of recommendations to address the complexities of retracted research throughout the scholarly communications ecosystem. -/- Results The RISRS recommendations are: (1) Develop a systematic cross-industry approach to ensure the public availability of consistent, standardized, interoperable, and timely information about retractions; (2) Recommend a taxonomy of retraction categories/classifications and corresponding retraction metadata that can be adopted by all stakeholders; (3) Develop best practices for coordinating the retraction process to enable timely, fair, unbiased outcomes; and (4) Educate stakeholders about pre- and post-publication stewardship, including retraction and correction of the scholarly record. -/- Conclusions Our stakeholder engagement study led to 4 recommendations to address inadvertent citation of retracted research, and formation of a working group to develop the Communication of Retractions, Removals, and Expressions of Concern (CORREC) Recommended Practice. Further work will be needed to determine how well retractions are currently documented, how retraction of code and datasets impacts related publications, and to identify if retraction metadata (fails to) propagate. Outcomes of all this work should lead to ensuring retracted papers are never cited without awareness of the retraction, and that, in public fora outside of science, retracted papers are not treated as valid scientific outputs.

This paper discusses and evaluates a recent argument for the conclusion that an attractive variety of Russellian monism ought to be regarded as a form of physicalism. According to this line of thought, if the Russellian’s “inscrutable” properties are held to ground not only experience, but also the physical structure of the world—and in this sense are not “experience-specific”—they thereby have an unproblematic place in physicalist metaphysics. I argue, in contrast, that there can be a sense in which the Russellian’s (...) inscrutables are experience-specific in a way that a physicalist probably ought to find objectionable, even if they play some role other than grounding experience. This will be the case, I argue, if certain worlds are taken to be possible, as they sometimes have: worlds of “bare structure” and worlds with what might be called “swapped inscrutables”. In this way, I claim that accepting certain possibilities has consequences for how one should understand the nature of the Russellian’s inscrutables and the place they have in physicalist metaphysics.

Crow Forefather had drawn a beautiful outfit for Peacock, but when it was the turn for Peacock to draw, Crow Forefather was in such a hurry to eat that he told Peacock to just pour the black ink bucket onto him. Since then, the Crows have lived with pit black, ugly-looking feathers.” -/- —In “Contentment”; The Kingfisher Story Collection [1].

In his metaphysical summa of 1986, The Plurality of Worlds, David Lewis famously defends a doctrine he calls ‘modal realism’, the idea that to account for the fact that some things are possible and some things are necessary we must postulate an infinity possible worlds, concrete entities like our own universe, but cut off from us in space and time. Possible worlds are required to account for the facts of modality without assuming that modality is primitive – that there are (...) irreducibly modal facts. We argue that on one reading, Lewis’s theory licenses us to assume maverick possible worlds which spread through logical space gobbling up all the rest. Because they exclude alternatives, these worlds result in contradictions, since different spread worlds are incompatible with one another. Plainly Lewis’s theory must be amended to exclude these excluders. But, we maintain, this cannot be done without bringing in modal primitives. And once we admit modal primitives, bang goes the rationale for Lewis’s modal realism. (shrink)

Conspiracy theories are spreading faster than ever and pose a real danger to our societies. It is natural to accuse the consumers of conspiracy theories of irrationality – that they are either not looking at or appropriately sensitive to all the available evidence. In this paper, I attempt to determine if we can make sense of this general idea. I argue that we cannot: conspiracy theories do not spread because the people who believe them are irrational – at least, (...) not necessarily so. In addition, I explore some alternative strategies for responding to the problem of the spread of conspiracy theories. I argue that in addition to confrontational strategies such as social shaming, we need more constructive programs of community activism to battle the spread of conspiracy theories. (shrink)

In a series of reflections published in the wake of the Covid-19 crisis, Giorgio Agamben expresses a number of concerns related to the way the pandemic has altered the very fabric of our societies, potentially changing it forever. While maintaining a certain scepticism towards the threat represented by the virus itself, Agamben claims that the response to the contagion shows how easy it is for authorities to limit individual freedoms in the name of public health, and how readily they are (...) willing to put such limitations in place. At the same time, the pandemic shows how easy it is for individuals to accept this situation as the new normal, and how readily they are willing to give up their freedoms and relationships. In this paper I offer a brief overview of Agamben’s worries, focussing on two issues in particular: the loss of individual freedom of movement and association, and the moral and political implications of social distancing. I then approach these issues from a different angle, making use of relational theory to propose an alternative framework which relies on the notion of vulnerability. While agreeing with Agamben that there is reason to worry about the state seizing the opportunity to exercise unchecked power over its citizens, I argue that we should pay attention to the ways in which social distancing measures can be grounded in solidarity and respect for the autonomy of vulnerable individuals.

In this paper, I analyze a type of externalist enactivism defended by Riccardo Manzotti. Such radical versions of enactivism are gaining more attention, especially in cognitive science and cognitive robotics. They are radical in that their notion of representation is purely referential, and content is conflated with reference. Manzotti follows in the footsteps of early causal theories of reference that had long been shown to be inadequate. It is commonly known that radical versions of externalism may lead to difficulties with (...) the notion of representation, especially if they cannot help themselves with the notion of syntax. I argue that a type of externalism present in Manzotti’s enactivism may well lead to anti-representationalism. (shrink)

The study aimed to investigate the reality of spreading the culture of entrepreneurship at Al-Azhar University from the point of view of students of the Faculty of Engineering and Information Technology and diagnose the most important obstacles that limit its activation. The researchers used the descriptive approach (survey) to achieve the objectives of the study, and relied on the questionnaire as a tool for applied study. The study concluded that: The reality of spreading the culture of entrepreneurship at Al-Azhar University (...) from the point of view of the students participating in the study came with an average degree of approval, while the most important obstacles and possible proposals for activating it came with a high degree of approval, which indicates the existence of strengths of Al-Azhar University in spreading the culture of entrepreneurship among students. Deficiencies must be corrected through proposals. In light of the results of the study, it was possible to develop a number of recommendations that can contribute to activating the culture of entrepreneurship at Al-Azhar University. Including the establishment of a specialized center for entrepreneurship within the university, develop a declared strategic plan to spread and develop the culture of entrepreneurship, allocate a sufficient budget to sponsor and support entrepreneurial ideas and projects for students and provide specialized cadres and certified trainers in the field of entrepreneurship.

We present a novel model of individual people, online posts, and media platforms to explain the online spread of epistemically toxic content such as fake news and suggest possible responses. We argue that a combination of technical features, such as the algorithmically curated feed structure, and social features, such as the absence of stable social-epistemic norms of posting and sharing in social media, is largely responsible for the unchecked spread of epistemically toxic content online. Sharing constitutes a distinctive (...) communicative act, governed by a dedicated norm and motivated to a large extent by social identity maintenance. But confusion about this norm and its lack of inherent epistemic checks lead readers to misunderstand posts, attribute excess or insufficient credibility to posts, and allow posters to evade epistemic accountability—all contributing to the spread of epistemically toxic content online. This spread can be effectively addressed if people and platforms add significantly more context to shared posts and platforms nudge people to develop and follow recognized epistemic norms of posting and sharing.

This article presents a new model for valuing a credit default swap (CDS) contract that is affected by multiple credit risks of the buyer, seller and reference entity. We show that default dependency has a significant impact on asset pricing. In fact, correlated default risk is one of the most pervasive threats in financial markets. We also show that a fully collateralized CDS is not equivalent to a risk-free one. In other words, full collateralization cannot eliminate counterparty risk completely (...) in the CDS market.

Persons and nations agree on the importance of justice but disagree on its requirements. In The End of History and the Last Man Francis Fukuyama argues that human history moves towards liberal democracy as the final ideal for all societies. It is conceivable that liberal democratic societies will converge to similar conceptions of justice and that global spread of liberal democracies will promote consensus. This paper tries to show that consensus on justice is, nevertheless, unlikely, due to reasonable disagreement. (...) Reason does not give a single rational or reasonable solution to conflicting demands of justice. This means that apart from reason, other factors play a role in what is regarded as just. Jurisdiction is influenced by tradition and zeitgeist. This explains why also liberal democracies, which may recognize similar principles of justice, still arrive at differing rankings of these principles and divergent results of jurisdiction in time and place.

Leading prescriptions for addressing the spread of fake news, misinformation, and other forms of epistemically toxic content online target either the platform or platform users as a single site for intervention. Neither approach attends to the intense feedback between people, posts, and platforms. Leading prescriptions boil down to the suggestion that we make social media more like traditional media, whether by making platforms take active roles as gatekeepers, or by exhorting individuals to behave more like media professionals. Both approaches (...) are impracticable and wrong. (shrink)

According to cultural evolutionary theory in the tradition of Boyd and Richerson, cultural evolution is driven by individuals' learning biases, natural selection, and random forces. Learning biases lead people to preferentially acquire cultural variants with certain contents or in certain contexts. Natural selection favors individuals or groups with fitness-promoting variants. Durham (1991) argued that Boyd and Richerson's approach is based on a "radical individualism" that fails to recognize that cultural variants are often "imposed" on people regardless of their individual decisions. (...) Fracchia and Lewontin (2005) raised a similar challenge, suggesting that the success of a variant is often determined by the degree of power backing it. With power, a ruler can impose beliefs or practices on a whole population by diktat, rendering all of the forces represented in cultural evolutionary models irrelevant. It is argued here, based on work by Boehm (1999, 2012), that, from at least the time of the early Middle Paleolithic, human bands were controlled by powerful coalitions of the majority that deliberately guided the development of moral norms to promote the common good. Cultural evolutionary models of the evolution of morality have been based on false premises. However, Durham (1991) and Fracchia and Lewontin's (2005) challenge does not undermine cultural evolutionary modeling in nonmoral domains. (shrink)

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

The spreading of false information on social media platforms is becoming increasingly common and thus, is creating an epistemic environment where people don’t know what to believe. Within this essay, I will argue that measures should be taken to address and reduce the spreading of false information on social media platforms, furthermore, accountability mechanisms should be implicated in order to do so.

The danger of deflation has been rather frequently mentioned recently among nu-merous concerns over the European and partly American economies. Analysts cite the Japanese economy which has been suffering from deflation for the last two decades despite the large investments in economy and the government's efforts to increase inflation. Similarly, notwithstanding many trillions of dollars, euro, pounds and yen that were invested in economies over the past few years, the infla-tion in the Western countries still remains low. On the whole, (...) there are reasons to maintain that European countries suffer from ‘the Japanese disease’, and this disease can progress or even become chron-ic. The USA, although to a lesser extent, has the signs of the disease as well. As a result, the financial infusions can become permanent, as it happened in Japan. The present paper defines the reasons of the problem, explains the irregularity of the inflation-deflation processes in the world and also offers some forecasts. (shrink)

After the death of Mevlana Celaleddin-i Rumi (d.1273), the cult of Mevlevi continued its structuring. Rumi's son Sultan Veled (d.1312) and his grandson Ulu Arif Çelebi (d.1320) contributed greatly to this structuring. Sultan Veled tried to turn the lodge he took over from his father into a systematic sect around Rumi's mystical thought and Mevlevi disciples. Ulu Arif Çelebi, on the other hand, is a very effective name in organizing Mevleviism as a cult. With his systematic studies and travels, he (...) made Mevlevi's spread in lodges and madrasahs, and he made efforts to teach Masnavi, the work of his grandfather Mevlana Celaleddin Rumi, in madrasahs. In addition, Ulu Arif Çelebi asked Ahmet Eflakî to write a book called Ariflerin Menkıbeleri about Rumi’s life, in order to keep his grandfather's memory alive. The entry of Mevlevi into the Ottoman State was through marriage. Mutahhare Hatun, daughter of Sultan Veled, was married to Süleyman Şah, the Germiyanoğulları leader. Süleyman Şah married the daughter of this marriage, Devlet Hatun, to Yıldırım Beyazıt, and left as a dowry Kütahya, Tavsanlı, Simav and Eğrigöz to Ottoman Empire. Yıldırım Bayezıd was appointed as the governor of Kütahya. Mehmet Çelebi was born from this marriage. The title of Çelebi is a title given to the descendants of Rumi, and Mehmet Çelebi, one of the sultans of the Fetret Period (A period of great depression), was one of the grandchildren of Rumi. The children of Mehmet Çelebi are remembered with the title of 'Çelebi'. Through this marriage, Mevlevi began to spread to the Ottoman Empire. Thus, Mevleviism would prevail in the Ottoman Empire, where Ahilik organization and Ahi culture prevailed, and Mevlevihane and Asitane would be established in many parts of the country with the support of the Ottoman State. Mevlana Celaleddin-i Rumi’nin (ö.1273) ölümünden sonra Mevlevilik bir tarikat olarak yapılanmasını sürdürmüştür. Mevlana’nın oğlu Sultan Veled’in (ö.1312) ve torunu Ulu Arif Çelebi’nin (ö.1320) bu yapılanmada katkısı oldukça büyüktür. Sultan Veled babasından devraldığı dergâhı, Mevlana’nın mistik düşüncesi çerçevesinde ve Mevlevi müritler etrafında sistemli bir tarikat haline getirmeye çalışmıştır. Ulu Arif Çelebi ise Mevleviliği bir tarikat olarak örgütlemede oldukça etkili bir isimdir. O sistematik olarak yaptığı çalışmalar ve seyahatlerle Mevleviliğin tekke, zaviye ve medreselerde yayılmasını sağladığı gibi dedesi Mevlana Celaleddin ’in eseri Mesnevi’nin medreselerde okutulması için de çaba sarf etmiştir. Ayrıca Ulu Arif Çelebi, dedesinin hatırasını canlı tutabilmek Ahmet Eflaki adındaki bir yazıcıya Mevlana’nın hayatını yazdırmıştır. (Ariflerin Menkıbeleri kitabı) Mevleviliğin Osmanlı Devleti’ne girişi evlilik yoluyla olmuştur. Sultan Veled’in kızı Mutahhare Hatun, Germiyanoğulları Beyi Süleyman Şah ile evlidir. Süleyman Şah bu evlilikten olan kızı Devlet Hatun’u Osmanlı Devleti’nin o dönem şehzadesi olan Yıldırım Beyazıt ile evlendirmiş ve çeyiz olarak Kütahya, Tavşanlı, Simav ve Eğrigöz dolaylarını Osmanlılara bırakmıştır. Yıldırım Bayezıd ise Kütahya valiliğine getirilmiştir. Bu evlilikten Mehmet Çelebi dünyaya gelmiştir. Çelebi unvanı Mevlana’nın soyundan gelenlere verilen bir unvandır ve Fetret Dönemi padişahlarından olan Mehmet Çelebi, Mevlana’nın torunlarındandır. Mehmet Çelebi’nin çocukları ‘çelebi’ unvanıyla anılmaktadır. Bu evlilik yoluyla Mevlevilik Osmanlı’da yayılmaya başlamıştır.

There are two foundational, but not fully developed, ideas in paraconsistency, namely, the duality between paraconsistent and intuitionistic paradigms, and the introduction of logical operators that express meta-logical notions in the object language. The aim of this paper is to show how these two ideas can be adequately accomplished by the Logics of Formal Inconsistency (LFIs) and by the Logics of Formal Undeterminedness (LFUs). LFIs recover the validity of the principle of explosion in a paraconsistent scenario, while LFUs recover the (...) validity of the principle of excluded middle in a paracomplete scenario. We introduce definitions of duality between inference rules and connectives that allow comparing rules and connectives that belong to different logics. Two formal systems are studied, the logics mbC and mbD, that display the duality between paraconsistency and paracompleteness as a duality between inference rules added to a common core– in the case studied here, this common core is classical positive propositional logic (CPL + ). The logics mbC and mbD are equipped with recovery operators that restore classical logic for, respectively, consistent and determined propositions. These two logics are then combined obtaining a pair of logics of formal inconsistency and undeterminedness (LFIUs), namely, mbCD and mbCDE. The logic mbCDE exhibits some nice duality properties. Besides, it is simultaneously paraconsistent and paracomplete, and able to recover the principles of excluded middle and explosion at once. The last sections offer an algebraic account for such logics by adapting the swap-structures semantics framework of the LFIs the LFUs. This semantics highlights some subtle aspects of these logics, and allows us to prove decidability by means of finite non-deterministic matrices. (shrink)

This paper presents the results of two corpus studies investigating the discourse surrounding conspiracy theories and genuine theories. The results of these studies show that conspiracy theories lack the epistemic and scientific standing characteristic of theories more generally. Instead, our findings indicate that conspiracy theories are spread in a manner that resembles the dissemination of rumors and falsehoods. Based on these empirical results, we argue that it is time for both re-engineering conspiracy theory and for relabeling "conspiracy theory". We (...) propose relabelling conspiracy theories as either "conspiracy stories" or "conspiracy narratives" to more accurately convey their true nature. (shrink)

Hume appeals to a mysterious mental process to explain how to world appears to possess features that are not present in sense perceptions, namely causal, moral, and aesthetic properties. He famously writes that the mind spreads itself onto the external world, and that we stain or gild natural objects with our sentiments. Projectivism is founded on these texts but it assumes a reading of Hume’s language as merely metaphorical. This assumption, however, conflicts sharply with the important explanatory role that “spreading” (...) and “staining” are supposed to play, which, ironically, is the very appeal of Hume’s texts to projectivists. In this paper, I first consider the difficulties readers of Hume have encountered in their attempts to ascertain nature of the key psychological process. I then identify in Hume’s texts novel theoretical resources that allow Hume to produce a satisfying answer to the question of process, that is, an account of the precise nature of the key process. I offer this explanation assuming what I take to be Hume’s austere conception of the elements involved in the process: sense impressions and “internal impressions” lacking intrinsic intentionality. On my reading, the spreading process explains the gap between the meager input and the rich, novel output: causal, moral and aesthetic judgments. (shrink)

In this article, we discuss the continued circulation and use of retracted science as a complex problem: Multiple stakeholders throughout the publishing ecosystem hold competing perceptions of this problem and its possible solutions. We describe how we used a participatory design process model to co-develop recommendations for addressing this problem with stakeholders in the Alfred P. Sloan-funded project, Reducing the Inadvertent Spread of Retracted Science (RISRS). After introducing the four core RISRS recommendations, we discuss how the issue of retraction-related (...) stigma gives rise to recommendation #4, Educate stakeholders about retraction and pre- and post-publication stewardship of the scholarly record. This recommendation is important for training publishing professionals and realizing this recommendation will require further collaborative design work across scholarly communications. We highlight ongoing stakeholder work which is now re-starting the design cycle. We conclude with a discussion of ongoing activities facilitating uptake and refinement of RISRS research and the implementation agenda. (shrink)

Translation (French to English) of Emmanuel Falque's "Le fou désincarné." I also wrote a translator's note, placed at the conclusion of the article. Phenomenology must begin to acknowledge the organic, animal nature of the body instead of focusing only on the pure subjectivity of the flesh. Mediating between Descartes's extended body (a mere object that is entirely distinct from the self) and Husserl's lived body (the flesh that is the self), the spread body is the organic body that I (...) have, that is not simply myself and yet is mine. This essay reveals the steep cost of phenomenology's neglect of the body, which produces a discarnation, or dissolution of the flesh itself. The "flesh without body" vanishes into transparency, exemplified by Descartes' "madmen" who lose all connection to their organic bodies, to the point of supposing that their bodies are glass. Because organicity is in fact proper to us, denying or rejecting its import can lead only to madness. (shrink)

This paper investigates a problem about freedom of information. Although freedom of information is generally considered desirable, there are a number of areas where there is substantial agreement that freedom of information should be limited. After a certain ordering of the landscape, I argue that we need to add the category of "dangerous" information and that this category has gained a new quality in the context of current information technology, specifically the Internet. This category includes information the use of which (...) would be morally wrong as well as some of what may be called "corrupting" information. Some such information should not be spread at all and some should be very limited in its spread. (shrink)

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.

Testimony spreads information. It is also commonly agreed that it can transfer knowledge. Whether it can work as an epistemic source of understanding is a matter of dispute. However, testimony certainly plays a pivotal role in the proliferation of understanding in the epistemic community. But how exactly do we learn, and how do we make advancements in understanding on the basis of one another’s words? And what can we do to maximize the probability that the process of acquiring understanding from (...) one another succeeds? These are very important questions in our current epistemological landscape, especially in light of the attention that has been paid to understanding as an epistemic achievement of purely epistemic value. Somewhat surprisingly, the recent literature in social epistemology does not offer much on the topic. The overarching aim of this paper is to provide a tentative model of understanding that goes in-depth enough to safely address the question of how understanding and testimony are related to one another. The hope is to contribute, in some measure, to the effort to understand understanding, and to explain two facts about our epistemic practices: the fact that knowledge and understanding relate differently to testimony, and the fact that some pieces of testimonial information are better than others for the sake of providing one with understanding and of yielding advancements in one’s epistemic standing.

A lump theorist claims that ordinary objects are spread out across possible worlds, much like many of us think that tables are spread out across space. We are not wholly located in any one particular world, the lump theorist claims, just as we are not wholly spatially located where one’s hand is. We are modally spread out, a trans-world mereological sum of world-bound parts. We are lump sums of modal parts. And so are all other ordinary objects. (...) In this paper, I explore lump theory and investigate five arguments against it. These arguments may be the primary reasons why lump theory has not been widely accepted––or extensively explored––until now. I maintain that these arguments can be answered, and moreover, that accepting lump theory has distinct advantages, making it a competitive view in its own right. (shrink)

Clark and Shackel have recently argued that previous attempts to resolve the two-envelope paradox fail, and that we must look to symmetries of the relevant expected-value calculations for a solution. Clark and Shackel also argue for a novel solution to the peeking case, a variant of the two-envelope scenario in which you are allowed to look in your envelope before deciding whether or not to swap. Whatever the merits of these solutions, they go beyond accepted decision theory, even contradicting (...) it in the peeking case. Thus if we are to take their solutions seriously, we must understand Clark and Shackel to be proposing a revision of standard decision theory. Understood as such, we will argue, their proposal is both implausible and unnecessary. (shrink)

In contrast to a stereotypical account of Indian philosophy that are entailments of the interpreter’s beliefs (an approach that violates basic standards of reason), an approach to Indian philosophy grounded on the constraints of formal reason reveals not only a wide spread disagreement on dharma (THE RIGHT OR THE GOOD), but also a pervasive commitment to the practical foundation of life’s challenges. The flip side of this practical orientation is the criticism of ordinary experience as erroneous and reducible to (...) the agent’s mental states. If we ignore the background practical orientation in Indian philosophy, this seems not like an error theory, that I call Ironic Idealism, but as a defense of idealism. I consider salient candidates for Indian Idealism (Advaita Vedānta, Yogācāra Buddhism, Kāśmīra Śaivism and the Yogavāsiṣṭha) and note that these positions continue a theme in Indian philosophy of articulating Ironic Idealism. Ironic Idealism depends upon the very Indian distinction between ultimate and provisional truth, and Ironic Idealism criticizes the mundane, provisional sort of "truth" as psychological and mental --- and ultimately false. Interpretation, the common approach to the study of Indian philosophy, is an example of what Ironic Idealism criticizes. This explains why authors incorrectly find Idealism everywhere in Indian thought. (shrink)

There has been much discussion on the two-envelope paradox. Clark and Shackel (2000) have proposed a solution to the paradox, which has been refuted by Meacham and Weisberg (2003). Surprisingly, however, the literature still contains no axiomatic justification for the claim that one should be indifferent between the two envelopes before opening one of them. According to Meacham and Weisberg, "decision theory does not rank swapping against sticking [before opening any envelope]" (p. 686). To fill this gap in the literature, (...) we present a simple axiomatic justification for indifference, avoiding any expectation reasoning, which is often considered problematic in infinite cases. Although the two-envelope paradox assumes an expectation-maximizing agent, we show that analogous paradoxes arise for agents using different decision principles such as maximin and maximax, and that our justification for indifference before opening applies here too.

How can we know whether we are punishing the same corporation that committed some past crime? Though central to corporate criminal justice, legal theorists and philosophers have yet to address the basic question of how corporate identity persists through time. Simple cases, where crime and punishment are close in time and the corporation has changed little, can mislead us into thinking an answer is always easy to come by. The issue becomes more complicated when corporate criminals undergo any number of (...) transformations—rebranding, spinning-off a division, merging, changing ownership, changing management, swapping lines of business, etc. These changes are common among all corporations, including those trying to conceal or limit liability for past crimes. This article takes a first step toward developing a workable and philosophically satisfying theory of corporate personal identity and discusses its prospects for fulfilling the retributive, rehabilitative, and deterrent purposes of criminal law.

Hobbes postulates a social contract to formalize our collective transition from the state of nature to civil society. The prisoner’s dilemma challenges both the mechanics and the outcome of that thought experiment. The incentives for reneging are supposedly strong enough to keep rational persons from cooperating. This paper argues that the prisoner’s dilemma undermines a position Hobbes does not hold. The context and parameters of the social contract steer it safely between the horns of the dilemma. Specifically, in a setting (...) as hostile as the state of nature, Hobbes’s emphasis on self-interest places a premium on survival, and thereby on adaptability, which then promotes progressive concessions toward peaceful coexistence. This transforms the relevant model of rationality from utility maximization to utility satisficing, thus favoring the pursuit of a mutually satisfactory outcome over that of the best personal outcome. The difference not only obviates the prisoner’s dilemma but also better approximates the state of nature while leaving a viable way out. (shrink)

Why is it good to be less, rather than more incoherent? Julia Staffel, in her excellent book “Unsettled Thoughts,” answers this question by showing that if your credences are incoherent, then there is some way of nudging them toward coherence that is guaranteed to make them more accurate and reduce the extent to which they are Dutch-bookable. This seems to show that such a nudge toward coherence makes them better fit to play their key epistemic and practical roles: representing the (...) world and guiding action. In this paper, I argue that Staffel’s strategy needs a small tweak. While she identifies appropriate measures of epistemic value, she does not identify appropriate measures of practical value. Staffel measures practical value using Dutchbookability scores. But credences have practical value in virtue of recommending actions that produce as much utility as possible. And while susceptibility to a Dutch book is a surefire sign that one’s credences are needlessly bad at this task, one’s degree of Dutch-bookability is not itself a good measure of how well they recommend practically valuable actions. Strictly proper scoring rules, I argue, are the right tools for measuring both epistemic and practical value. I show that we can rerun Staffel’s strategy swapping in strictly proper scoring rules for Dutch-bookability measures. So long as one’s epistemic scoring rule and practical scoring rule are “sufficiently similar,” there is some way of nudging incoherent credences toward coherence that is guaranteed to yield more of both types of value.

While spreading wide-world, the new coronavirus Sars-CoV-2 made changes in many social departments of our society on levels we never thought about and messes with all our cultural habits. Thus, we witnessed that the religious denominations took into consideration changes without precedent in their cultic history and thus dogmatic as well concerning the actual threat of Coronavirus. We saw for example the Roman-Catholic Church who suspended all masses here and there[1] at first or banned the crucial gestures in rituals [to (...) suspend the distribution of Holy Communion from the Chalice[2], to distribute the Eucharist preferably into the hands of the faithful, and to avoid the physical contact from a peaceful handshake, to forego ash crosses on forehead, to suspend placing water in holy water fonts at the entrance of churches, that the churchgoers "refrain" from kissing or touching the cross for veneration, or even cancellation of masses]. We witnessed Buddhist temples and Protestant churches around Korea [at first] and beyond that have also suspended religious gatherings, and so on. In my case, the Romanian Orthodox Church did the same thing[3], but in a controversial way, firstly making some recommendations for its believers [e.g. not to kiss public icons in Churches, but their indoor ones, and receive Holy Communion with teaspoons for single-use]; afterward same Church reconsidered these recommendations and withdrew its decision [perhaps at the pressure of civil fundamentalists]. How can we qualify all these measures and, moreover, the withdrawal on behalf of religious believers, as weakness, populism, diligence, assuming the human limits, or...something else? What would be the correct and coherent answer religion should assume in this particular regard, and especially what are the reasons to qualify it in a way or another? (shrink)

Having been influenced by John Perry's 1997 article, "Indexicals and Demonstratives," in this paper I take a closer look at contexts for indexicals, more specifically the indexical "I." (N.B. The adjective in the title is not misspelt; it is used in the sense of the leading brand of premium vodka.).
