Typically, public discussions of questions of social import exhibit two important properties: they are influenced by conformity bias, and the influence of conformity is expressed via social networks. We examine how social learning on networks proceeds under the influence of conformity bias. In our model, heterogeneous agents express public opinions where those expressions are driven by the competing priorities of accuracy and of conformity to one’s peers. Agents learn, by Bayesian conditionalization, from private evidence from nature, and from the public (...) declarations of other agents. Our key findings are that networks that produce configurations of social relationships that sustain a diversity of opinions empower honest communication and reliable acquisition of true beliefs, and that the networks that do this best turn out to be those which are both less centralized and less connected.

The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central. The direct interaction between individuals, firms and banks does not simply produce imperfections in the functioning of the economy but is the very basis of the functioning of a modern economy. This (...) book suggests a way of analysing the economy which takes this point of view. The economy should be considered as a complex adaptive system in which the agents constantly react to, influence and are influenced by, the other individuals in the economy. In such systems which are familiar from statistical physics and biology for example, the behaviour of the aggregate cannot be deduced from the behaviour of the average, or "representative" individual. Just as the organised activity of an ants’ nest cannot be understood from the behaviour of a "representative ant" so macroeconomic phenomena should not be assimilated to those associated with the "representative agent". This book provides examples where this can clearly be seen. The examples range from Schelling’s model of segregation, to contributions to public goods, the evolution of buyer seller relations in fish markets, to financial models based on the foraging behaviour of ants. The message of the book is that coordination rather than efficiency is the central problem in economics. How do the myriads of individual choices and decisions come to be coordinated? How does the economy or a market, "self organise" and how does this sometimes result in major upheavals, or to use the phrase from physics, "phase transitions"? The sort of system described in this book is not in equilibrium in the standard sense, it is constantly changing and moving from state to state and its very structure is always being modified. The economy is not a ship sailing on a well-defined trajectory which occasionally gets knocked off course. It is more like the slime described in the book "emergence", constantly reorganising itself so as to slide collectively in directions which are neither understood nor necessarily desired by its components.

Patient rights are universal values which we have to adopt. It is not so easy, however, to put such values and principles into effect. As approaches and attitudes differ from individual to individual, from society to society, and from country to country, a uniform application of these values is difficult. If we want to reach a general conclusion about the status of patient rights in the world as whole, we should examine the situation in individual countries. As far as Turkey (...) is concerned, we can say that, although the idea of patient rights is accepted in principle, patient rights have yet to be adequately implemented. (shrink)

The study of social justice asks: what sorts of social arrangements are equitable ones? But also: how do we derive the inequitable arrangements we often observe in human societies? In particular, in spite of explicitly stated equity norms, categorical inequity tends to be the rule rather than the exception. The cultural Red King hypothesis predicts that differentials in group size may lead to inequitable outcomes for minority groups even in the absence of explicit or implicit bias. We test this prediction (...) in an experimental context where subjects divided into groups engage in repeated play of a bargaining game. We ran 14 trials involving a total of 112 participants. The results of the experiments are statistically significant and suggestive: individuals in minority groups in these experiments end up receiving fewer resources than those in majority groups. Combined with previous theoretical findings, these results give some reason to think that the cultural Red King may occur in real human groups. (shrink)

Although modern technical and scientific developments in medicine are followed closely in Turkey, it cannot be claimed that the same is true in the field of bioethics. Yet, more and more attention is now being paid to bioethics and ethics training in health sciences. In addition, there are also legal regulations in bioethics, some of which are not so new. The objective of these regulations is to provide technical and administrative control. Ethical concerns are rather few. What attracts our attention (...) most in these regulations is the presence of the idea of "consent". (shrink)

Economics: Beyond the Millennium contains articles by leading authorities in various fields of economic theory and econometrics, each of whom gives an account of the current state of the art in their own field and indicate the direction that they think it will take in the next ten years. The fields covered are grouped into three categories: the microfoundations of macroeconomics, where Malinvaud evaluates the theory of resource allocation and Hildenbrand examines the empirical content of economic thories; markets and and (...) organizations, where both Gabszewicz and D'Aspremont et al. look at imperfect competition and general equilibrium, Scotchmer and Thiess consider spatial economics, Ponssard the future of managerial economics, while Van Damme looks at the next stage of game theory; and econometrics, where Gourieroux reviews econometric modelling in general, Maravall looks at time series, Lubrand and Bauwens examine Bayesian analysis, and Blundell looks at the rapidly expanding area of microeconometrics.

The replicator dynamics and Moran process are the main deterministic and stochastic models of evolutionary game theory. The models are connected by a mean-field relationship—the former describes the expected behavior of the latter. However, there are conditions under which their predictions diverge. I demonstrate that the divergence between their predictions is a function of standard techniques used in their analysis and of differences in the idealizations involved in each. My analysis reveals problems for stochastic stability analysis in a broad class (...) of games, demonstrates a novel domain of agreement between the dynamics, and indicates a broader moral for evolutionary modeling.

A pós-fenomenologia é um enfoque na filosofia da tecnologia que investiga como as tecnologias influenciam e moldam o mundo e o ego. Embora a pós-fenomenologia tenha expressado desde o início a ambição de oferecer uma estrutura não-essencialista e não-fundacionista, o desenvolvimento estrutural desse aspecto está virtualmente ausente. O pragmatismo peirciano, como será proposto, pode fornecer essa estrutura, bem como os blocos de construção para o desenvolvimento da visão da autoformação em termos de sublimação. Essa visão tenta reconhecer que nosso ambiente, (...) que é cada vez mais um ambiente tecnológico e sujeito à mudança radical, molda consideravelmente quem nós somos e influencia quem deveremos ser. E, ao mesmo tempo, resiste à ideia de que o ego não é mais do que um joguete de influências e forças contingentes. (shrink)

Scientific curation, where scientific evidence is selected and shared, is essential to public belief formation about science. Yet common curation practices can distort the body of evidence the public sees. Focusing on science journalism, we employ computational models to investigate how such distortions influence public belief. We consider these effects for agents with and without confirmation bias. We find that standard journalistic practices can lead to significant distortions in public belief; that preexisting errors in public belief can drive further distortions (...) in reporting; that practices that appear relatively unobjectionable can produce serious epistemic harm; and that, in some cases, common curation practices related to fairness and extreme reporting can lead to polarization.

Brain imaging technologies are increasingly used to find networks and brain regions that are specific to the functional realization of particular aspects of the self. In this paper, we aim to show how neuroscientific research and techniques could be used in the context of self-formation without treating them as representations of an inner realm. To do so, we show first how a Cartesian framework underlies the interpretation and usage of brain imaging technologies as functional evidence. To illustrate how material-technological inventions (...) and developments can have a significant and lasting impact on views of the self, we show how this framework was influenced by another technology: the camera obscura. Subsequently, we show that brain imaging technologies challenge the idea that privileged access to the self can be obtained merely through introspection, indicating a strong discontinuity between the Cartesian and the current neuroscientific framework. Building on these insights, we reframe the self in terms of self-formation. This view neither regards the brain as an independent realizer of aspects of the self, nor assumes that self-knowledge can be obtained through introspection. From this perspective, self-formation is realized throughcritical self-identification: instead of offering representational knowledge of an ‘inner self,’ the potential use of brain imaging technologies within this framework lies in their capacity to offer what we call ‘extrospective knowledge’ that pragmatically can contribute to self-formation. Brain imaging technologies contribute to this process because they foreground our neurophysiology, which helps to critically integrate biological aspects into self-formation. (shrink)

In economics in situations where there is uncertainty one has to attribute some attitude to handling this uncertainty to individuals. The original idea was to assume that “people do not make systematic mistakes” for which Muth coined the term “rational expectations”. This was replaced by a much more formal vision which suggested that people fully understand how the economy evolves. In this paper I will argue that the foundations of the “rational expectations” hypothesis which has underpinned most recent modern macroeconomic (...) models, which have, in turn, been used for policymaking, are unsound. From a philosophical point of view the idea that agents can not only forecast the evolution of their environment but also their own evolution seems unjustified. If agents do manage to coordinate on specific expectations these may not be rational and can be self fulfilling. From an econometric point of view, when there are changes in the evolution of the economy, it is not rational to satisfy the hypothesis. Furthermore the empirical and experimental evidence suggests that we should abandon this route. (shrink)

Cette communication traite de l'utilisation des concepts évolutionnaires en économie. Une approche a été d'utiliser Vidée de révolution comme une vague analogie. Il y a deux exemples de ce type d'approche. Certains; comme Friedman, ont utilisé la notion de sélection naturelle afin de justifier le modèle standard de la théorie économique, celui d'Arrow-Debreu. D'autres ont utilisé l'idée d'évolution comme base à une critique de la nature fermée et statique de ce modèle. Une autre approche a été de prendre l'idée de (...) l'évolution au sérieux, comme cela a été fait en théorie des jeux évolutionnaires. Je suggère que même dans ce cas, le modèle standard est incompatible avec un point de vue évolutionniste et qu'il ne suffit pas d'utiliser l'évolution comme outil pour sélectionner parmi les équilibres statiques. Des modèles économiques compatibles avec une approche évolutionnaire doivent nécessairement être très différents des modèles standards qu 'on utilise aujourd'hui.This article discusses the use of evolutionary concepts in economic theory. One approach has been to use evolution as a loose analogy. There have been two principle examples of this approach. Those such as Friedman who have used the notion of "natural selection" to justify' the standard model in economic theory, that of Arrow-Debreu and those who have used it to criticize that model for its closed and static nature. A second approach has been to take the idea of evolution more seriously as has been done in evolutionary game theory. I suggest that even in this latter case the standard model is incompatible with a truly evolutionist view and it is not enough to use evolution as a tool to select amongst static equilibria. Economic models which are consistent with an evolutionary approach have necessarily to be very different from the standard ones in use. (shrink)

According to Max Weber, the “fate of our times” is characterized by a “disenchantment of the world.” The scientific ambition of rationalization and intellectualization, as well as the attempt to master nature through technology, will greatly limit experiences of and openness for the transcendent, i.e. that which is beyond our control. Insofar as transcendence is a central aspect of virtually every religion and all religious experiences, the development of science and technology will, according to the Weberian assertion, also limit the (...) scope of religion. In this paper, we will reflect on the relations between technology and transcendence from the perspective of technological mediation theory. We will show that the fact that we are able to technologically intervene in the world and ourselves does not imply that we can completely control the rules of life. Technological interference in nature is only possible if the structures and laws that enable us to do that are recognized and to a certain extent obeyed, which indicates that technological power cannot exist without accepting a transcendent order in which one operates. Rather than excluding transcendence, technology mediates our relation to it. (shrink)

The author of this paper starts by sketching a general framework for Peirce's ethical theory: first, he discusses very briefly Peirce's phenomenological categories; then, he outlines some implications of these categories for Peirce's concept of personal identity. In the rest of the paper he discusses successively within this framework Peirce's views on the status of ethics, ideals, concrete reasonableness, evolutionary love, and the relation between the individual and the cosmos. He then argues that these notions, taken together, culminate in a (...) non-subjective ethical theory that indicates what is a good life. The central argument that he develops is that we, according to Peirce, can only become authentic persons through a process of giving a general form to our interactions with our social and natural environment, i.e., a form that is constituted by virtue of the belief in and embodiment of common ideals, which are no less real than concrete, physical events.

This book investigates how we should form ourselves in a world saturated with technologies that are profoundly intruding in the very fabric of our selfhood. How do we recognize that smart technological environments, imaging technologies and smart drugs increasingly shape who and what we are and influence who we ought to be? Tackling this issue requires going beyond the persistent and stubborn inside-outside dualism and recognizing that what we consider our "inside" self is to a great extent shaped by our (...) "outside" world. Inspired by various philosophers - especially Nietzsche, Peirce and Lacan -this book demonstrates that the values, goals and ideals that humans encounter in their environments not only shape their identities but also enable them to critically relate to their present state. The author argues against understanding technological self-formation in terms of making ourselves better, stronger, and smarter. Rather, we should conceive it in terms of technological sublimation, which redefines the very notion of human enhancement. In this respect the author introduces an alternative, more suitable theory, namely Technological Sublimation Theory (TST). Extimate Technology will be of interest to scholars and advanced students working in philosophy of technology, philosophy of the self, phenomenology, pragmatism, and history of philosophy. (shrink)

Bu makalenin amacı, Türkiye örnekleminde Tanrı algısı üzerine yapılmış ampirik araştırmaların sistematik bir incelemesini sunmaktır. Tanrı algısı çok boyutlu bir yapı olarak ele alınmış ve Tanrı algısının sosyodemografik ve psikolojik süreçleri içeren diğer değişkenlerle ilişkisi tartışılmıştır. Tanrı algısı ile psikopatoloji ve manevi bakım arasındaki ilişki de gözden geçirilmiştir. İnceleme sonucunda Tanrı algısının yaşa göre her zaman anlamlı bir farklılık göstermediği ancak ilişkinin olumlu yönde seyrettiği, yaş ilerledikçe Tanrı algısının daha olumlu olduğu söylenebilir. Cinsiyet farklılığına bakıldığında kadınların erkeklere göre daha olumlu (...) bir Tanrı algısına sahip oldukları, gelir düzeyi ve eğitim düzeyi açısından ise anlamlı bir farklılığın olmadığı görülmüştür. Ayrıca Tanrı algısının okul türüne göre (dini ve seküler okullar) farklılık gösterebildiği, Tanrı algısının oluşumunda anne baba tutumlarının önemli olduğu görülmüştür. Çalışmalar baskıcı, otoriter veya ilgisiz/ ihmalkar anne baba tutumları ile büyüyen insanların Tanrı algılarının daha korku yönelimli olduğunu, demokratik anne baba tutumları ile büyüyenlerin ise daha sevgi yönelimli Tanrı algıları olduğunu göstermiştir. Öznel dindarlık ve olumlu dini başa çıkmanın Tanrı algısı ile pozitif ilişkili olabildiği sonucuna varılmıştır. Sosyodemografik değişkenlere ek olarak, sevgi yönelimli Tanrı algısının daha iyi psikolojik sağlık, daha yüksek iyi oluş, etkili ve olumlu başa çıkma, olumlu benlik saygısı, daha düşük depresyon ve daha düşük psikopatolojik belirtilerle pozitif yönde ilişkili olduğu söylenebilir. Gözden geçirilen 55 çalışma içerisinde pek çok bulguya ulaşılmış olsa da incelenen değişkenlerin çok çeşitli olduğu, ancak her değişken hakkında genel bir çıkarım yapmak için yeterli çalışma olmadığı, bu nedenle halen Türkiye örnekleminde Tanrı algısı ile ilgili çalışmaların artırılması gerektiği düşünülmektedir. Son olarak, daha fazla araştırmaya ihtiyaç duyulan alanlar tartışma bölümünde ele alınmıştır. (shrink)

After several technological revolutions in which technologies became ever more present in our daily lives, the digital technologies that are currently being developed are actually fading away from sight. Information and Communication Technologies are not only embedded in devices that we explicitly “use” but increasingly become an intrinsic part of the material environment in which we live. How to conceptualize the role of these new technological environments in human existence? And how to anticipate the ways in which these technologies will (...) mediate our everyday lives? In order to answer these questions, we draw on two approaches that each offers a framework to conceptualize these new technological environments: Postphenomenology and Material Engagement Theory. As we will show, each on their own, these approaches fail to do justice to the new environmental role of technology and its implications for human existence. But by bringing together Postphenomenology’s account of technological mediation and Material Engagement Theory’s account of engaging with environments, it becomes possible to sufficiently account for the new environmental workings of technology. To do justice to these new workings of environmental technologies, we introduce and develop the concept of “Technological Environmentality.”. (shrink)

Muammar b. Abbād al-Sulamī (d.215/830) was one of the most influential figures of his time in terms of recognizing things and making sense of the changes in the universe, which occupies an important place in Islamic thought. Muammar, who was a Basra Mu'tazilite, appears especially with his naturalistic ideas. What makes him stand out is that he also embraced atomism. Although the atomist conception was of foreign origin, the theologians revised it according to their theological views. This view was also (...) presented as a proof of God’s constant activity in the universe. Muammar, who also defined substance, body and accident, which are the basic concepts of kalam cosmology, influenced other theologians, especially with his definition of body. For Muammar, things have a nature. The body creates its accidents as a result of its own nature. Ultimately, in his thought, it is God who gives this nature to the body. Therefore, he accepts that the functioning of the universe takes place within the framework of the laws that God has set in the universe. This idea of Muammar’s about the nature of bodies is actually to demonstrate that the universe functions in a tremendous way in this way. The concept of māna, which is based on Muammar’s thought, occupies an important place at this point. With this concept, which is identified with the understanding of nature, he aimed to exclude the essence of God from the beings. In his view, this concept is also active when it comes to God’s attributes. For him, that’s why God is the wise and the powerful by means of the knowledge and the power that He possesses through the māna. According to Muammar, māna means cause. He argues that the separation of a moving object from an immobile object is the result of a māna. Therefore, objects are also differentiated from each other through a māna. A māna can exist with a māna, which brings forth the idea of the infinity of māna. However, the infinity of māna does not mean the infinity of things. Muammar’s most criticized point is the nature of objects and the fact that they undergo change as a result of this nature, that is, they create their accidents. In this case, the concept of continuous re-creation, which is generally accepted in theology, does not fit Muammar’s system. For Muammar, there is a system based on cause and effect. Although there are criticisms that this relationship he defended belongs to a strict determinist approach, in fact, it can be said that he was concerned with excluding God from situations that take place on the plane of time and space, such as movement and change. Compared to other contemporary theologians who held naturalistic views like him, Muammar’s justification of nature on the basis of māna sets him apart from the others. (shrink)

The practice of HARKing---hypothesizing after results are known---is commonly maligned as undermining the reliability of scientific findings. There are several accounts in the literature as to why HARKing undermines the reliability of findings. We argue that none of these is right and that the correct account is a Bayesian one. HARKing can indeed decrease the reliability of scientific findings, but it can also increase it; which effect HARKing produces depends on the difference of the prior odds of hypotheses characteristically selected (...) ex ante and ex post to observing data. Further, we show how misdiagnosis of HARKing can lead to misprescription in the context of the replication crisis. (shrink)

Futures contracts in agricultural commodities are an agreement to buy or sell a predetermined amount of agricultural commodities (such as wheat, corn, cotton, soybeans, live pork, live cattle, cocoa, etc.) at a specific price depending on the price on a specific date in the future. Futures contracts in agricultural commodities are carried out under “commodity futures contracts” on the futures exchange. These contracts are executed in two ways in terms of the delivery of the contract subject; physical delivery and cash (...) settlement. In the physical delivery, the underlying asset is physically received at the end of maturity. In our country, physical delivery method is used in futures contracts made on commodities. In the second contract method that results in cash settlement, there is no physical delivery of the underlying asset at the end of maturity. The transaction takes place over the settlement price at the end of maturity. Futures contracts in agricultural commodities can be analyzed in two categories in terms of Islamic law. First, within the scope of sales where both the goods and the price are on credit; the second is a combined contract that includes a promise to sell and a contract of sale when due. It is more convenient to analyze in the former because the agricultural commodities in the warehouse are kept ready to be delivered when due and the commodities price is also delivered on time. In this category, it resembles the sale of a credit on credit, which is prohibited in Islamic law. We can see that there are five parties within the exchange organization regarding the futures contracts in agricultural commodities; futures and options exchange, clearing house, brokerage houses, market participants, supervisory institutions. When the transactions of the related parties are examined in terms of legal capacity and power of representation; it is observed that brokerage houses transacting on behalf of sellers and customers operate by proxy. On the other hand, the Exchange, the Clearinghouse (Takasbank) and the custody warehouse within the scope of the exchange system; carries out transactions on behalf of the parties both as a proxy and a guarantor. Therefore, this futures transaction has the nature of containing more than one contract. When analyzed in terms of the establishment of the contract; if there are agricultural commodities that are considered as legitimate property of the Islamic law (mütekavvim), there is no objection regarding the parties and the offer-acceptance. In addition the delivery time of the commodity subject to the contract must be equal to the amount sold and the amount in the warehouse, which is guaranteed to be in the warehouse. In terms of invalid condition, one-sided benefit causing conflict for the parties contains something prohibited by the legal order. It is seen that it does not contain conditions contrary to the content of the contract and established practices. However, except for the condition that the collateral is retained with interest income in direct proportion to the period of stay in the Clearinghouse (Takasbank), in order to obtain the highest return. In terms of enforcement conditions, after the approval of the buyer and seller, transactions are carried out within the exchange system without asking for the right and approval of another person. Therefore, this contract can be considered as a running contract. In terms of the bindingness of this contract; at first glance, it can be seen as a mutual promise and non-obligatory promise based on the fact that the commodity and its price are not cash. But when the subject is examined in depth, it turns out to be a different situation. Because both parties are under mutual obligation by paying the guarantee stipulated by the Exchange, one party is obliged to deliver the commodity on time and the other party to deliver the price. In addition, the contract does not allow the parties to imagine the right. So, this contract can be considered as an obligatory contract. However, based on the current functioning futures contracts in agricultural commodities as a whole, it is considered unappropriate to Islamic law. In this study, first, the nature of futures contracts in agricultural commodities that are not deemed suitable for Islamic law in its current form are determined. Then, an analysis from the point of view of Islamic law was made and some offers were made for a model that was reconfigurated according to Islamic law. (shrink)

This paper explains why Clark’s Extended Mind thesis is not capable of sufficiently grasping how and in what sense external objects and technical artifacts can become part of our human cognition. According to the author, this is because a pivotal distinction between inside and outside is preserved in the Extended Mind theorist’s account of the relation between the human organism and the world of external objects and artifacts, a distinction which they proclaim to have overcome. Inspired by Charles S. Peirce’s (...) philosophy of mind, in particular, the author tries to find a way out of this ‘inside–outside’ fallacy. External objects, artifacts or processes should, according to him, not be conceived as inanimate and unintelligent matter utilised by a separately living, inner mental sphere that has set certain pre-established goals for itself. Mind has rather an artifactual character. It is not extended by an inner biological cognitive core but rather unfolds itself through objects and artifacts. Mind as such is, especially in our modern technological culture, shaped by virtue of and through technical artifacts. Recognizing this artifactual dimension of mind will, the author concludes, enable a more critical analysis of contemporary claims that ascribe certain original and irreducible features to thinking.

In this paper, the author aims to show that transhumanists are confused about their own conception of the posthuman: transhumanists anticipate radical transformation of the human through technology and at the same time assume that the criteria to determine what is “normal” and what is “enhanced” are univocal, both in our present time and in the future. Inspired by Nietzsche’s notion of the Overhuman, the author argues that the slightest “historical and phenomenological sense” discloses copious variations of criteria, both diachronic (...) and synchronic, for what can be considered “normal” and “enhanced.” Radical transformation through technology does not simply enable us to become “stronger,” “smarter,” or “healthier,” but it can and often will also change the very standard or yardstick with which we measure what counts as “stronger,” “smarter,” or “healthier.” Put yet differently: new and emerging technologies are not neutral means but often bring about different and, from our current perspective, foreign standards for determining what are “normal” and “enhanced” capacities. Since the qualitative meanings of these terms are themselves not fixed, it is unintelligible and too reassuring to simply predict that new technologies will enhance human beings. (shrink)
