argued that there are two options for what he called a realistic solution to the quantum measurement problem: (1) select a preferred set of observables for which definite values are assumed to exist, or (2) attempt to assign definite values to all observables simultaneously (1810–1). While conventional wisdom has it that the second option is ruled out by the Kochen-Specker theorem, Vink nevertheless advocated it. Making every physical quantity determinate in quantum mechanics carries with it significant conceptual costs, (...) but it also provides a way of addressing the preferred basis problem that arises if one chooses to pursue the first option. The potential costs and benefits of a formulation of quantum mechanics where every physical quantity is determinate are herein examined.

We start by very briefly describing the measurement problem in quantum mechanics and its solution by the Many Worlds Interpretation. We then describe the preferred basis problem, and the role of decoherence in the MWI. We discuss a number of approaches to the preferred basis problem and argue that contrary to the received wisdom, decoherence by itself does not solve the problem. We address Wallace’s emergentist approach based on what he calls Dennett’s (...) criterion, and we compare the logical structure of Wallace’s argument that the Hilbert space structure and the unitary dynamics should be considered a complete description of the physics of the universe with the logical structure of the EPR argument against the completeness of quantum mechanics. Then, we consider the nature of so-called “high level emergent facts” and Dennett’s criterion in Wallace’s approach and we discuss the implications of its non-reductive nature. Finally, we conclude that the MWI is not a straightforward interpretation of pure quantum mechanics that doesn't add anything to it. Whether or not it is more parsimonious than other quantum mechanical theories depends on the details of the additions. (shrink)

I argue that the many worlds explanation of quantum computation is not licensed by, and in fact is conceptually inferior to, the many worlds interpretation of quantum mechanics from which it is derived. I argue that the many worlds explanation of quantum computation is incompatible with the recently developed cluster state model of quantum computation. Based on these considerations I conclude that we should reject the many worlds explanation of quantum computation.

It is emphasized that a many-worlds interpretation of quantum theory exists only to the extent that the associated basis problem is solved. The core basis problem is that the robust enduring states specified by environmental decoherence effects are essentially Gaussian wave packets that form continua of non-orthogonal states. Hence they are not a discrete set of orthogonal basis states to which finite probabilities can be assigned by the usual rules. The natural way to get an (...) orthogonal basis without going outside the Schroedinger dynamics is to use the eigenstates of the reduced density matrix, and this idea is the basis of some recent attempts by many-worlds proponents to solve the basis problem. But these eigenstates do not enjoy the locality and quasi-classicality properties of the states defined by environmental decoherence effects, and hence are not satisfactory preferred basis states. This core problem is obscured by approaches that treat the universe as a quantum computer, but it needs to be addressed and resolved before a many-worlds-type interpretation can be said to exist.

I introduce and review the most recent and most promising model of state vector reduction, that of Ghirardi, Rimini, Weber, and Pearle. This model requires the specification of a reduction basis. At least two questions therefore arise: Are there physical reasons to choose one basis rather than another? Does the choice made lead to any undesirable consequences? I argue that there arephysical reasons to choose from a certain class of reduction bases (a class which includes the choice made (...) by the authors mentioned above), and that such a choice does not lead to problems, contra an argument by Albert and Vaidman.

Like many, I find the idea of relying on patient preference predictors in life-or-death cases ethically troubling. As part of his stimulating discussion, Sharadin1 diagnoses such unease as a worry that using PPPs disrespects patients’ autonomy, by treating their most intimate and significant desires as if they were caused by their demographic traits. I agree entirely with Sharadin’s ‘debunking’ response to this concern: we can use statistical correlations to predict others’ preferences without thereby assuming any causal claim. However, I suspect (...) that, for at least some of us, our unease about PPPs stems from a different kind of ‘autonomy’ concern. In this commentary, then, I will explore this concern, and show how it relates to Sharadin’s work. Very many of our preferences are caused, ultimately, by facts which are outside our control, such as our demographic features. However, I suggest that we can still act autonomously on the basis of such preferences, when they are preferences which we endorse. Imagine, for example, that Jane has grown up in a church-growing environment, which has shaped many of her preferences, …. (shrink)

This paper deals with various connections that are found to exist between statistical estimation methods for decision-making and rules of group choice in the social choice area. Initially the aggregation of individual opinions is formulated as a pattern recognition problem; firstly it is shown that individual preferences lead to a natural representation in terms of binary patterns. Then we proceed to show how the search for a group preference pattern can be conducted by classifying the input preference patterns into (...) various ‘pattern classes’ and using the resulting classification boundaries to define the area of mutual agreement over some of the available alternatives. This leads to a decision-theoretic problem which consists in defining a decision rule (for classification) that is least likely to lead to misrecognition of arbitrary preference patterns. A maximum likelihood solution is obtained and compared with some well-known rules of group decision-making. Other solutions are also possible, on the basis of different optimality criteria, and their social choice interpretation is suggested. Finally, a method using Coleman's linear model for attributes is applied to yield group decision rules by feature weighting of election issues. (shrink)

Kyle Stanford has recently given substance to the problem of unconceived alternatives, which challenges the reliability of inference to the best explanation (IBE) in remote domains of nature. Conjoined with the view that IBE is the central inferential tool at our disposal in investigating these domains, the problem of unconceived alternatives leads to scientific anti-realism. We argue that, at least within the biological community, scientists are now and have long been aware of the dangers of IBE. We re-analyse (...) the nineteenth-century study of inheritance and development (Stanford’s case study) and extend it into the twentieth century, focusing in particular on both classical Mendelian genetics and the studies by Avery et al. on the chemical nature of the hereditary substance. Our extended case studies show the preference of the biological community for a different methodological standard: the vera causa ideal, which requires that purported causes be shown on non-explanatory grounds to exist and be competent to produce their effects. On this basis, we defend a prospective realism about the biological sciences. 1 Introduction2 Stanford on Unconceived Alternatives3 Pangenesis: A Re-analysis4 The Vera Causa Ideal I: Negative Aspect5 Rendering Heredity Accessible6 The Vera Causa Ideal II: Positive Aspect7 Implications for Scientific Realism8 Conclusion.

The article presents the results of a survey of Odessa residents as part of a study of the motivational and value preferences of townsfolk in the field of fitness. It has been established that the determining motives for choosing a place for fitness are the individual trainer's approach to the client, personal comfort and convenient location of the fitness club. It was revealed that respondents have an interest in innovative training, but it has not yet acquired the character of a (...) trend. We also obtained data about the significance of playing sports under the supervision of a personal trainer and sports physician. The collected empirical material served as the basis for revealing the behavioral patterns of townspeople and allowed to identify three groups of city residents who are characterized by different motivational and value preferences in the field of fitness. The first ones are focused on personal achievements, the second – on health, good physical form, good time among like-minded people, the third – on the development of special skills, achievements and opportunities to escape from problems. Based on the survey, it was also revealed that the overall physical development of the child is the leading physical motivation for children to do sports, and despite the fact that children may have certain achievements in sports, parents do not attach much importance to them.

-/- This unique book develops an operational approach to preference and rationality as the author employs operators over binary relations to capture the concept of rationality. -/- A preference is a basis of individual behavior and social judgment and is mathematically regarded as a binary relation on the set of alternatives. Traditionally, an individual/social preference is assumed to satisfy completeness and transitivity. However, each of the two conditions is often considered to be too demanding; and then, weaker rationality conditions (...) are introduced by researchers. This book argues that the preference rationality conditions can be captured mathematically by “operators,” which are mappings from the set of operators to itself. This operational approach nests traditional concepts in individual/social decision theory and clarifies the underlying formal structure of preference rationality. -/- The author also applies his approach to welfare economics. The core problem of ‘new welfare economics,’ developed by Kaldor, Hicks, and Samuelson, is the rationality of social preference. In this book the author translates the social criteria proposed by those three economists into operational forms, which provide new insights into welfare economics extending beyond ‘new welfare economics.’ .

Despite the hadiths and narratives that warn about the interpretation of the Qur’ān by opinion, the question of how Qur’ānic verses can be understood is about the nature of Qur’ānic exegesis. These narratives, which limit the interpretation to the exact field and indicate the invalidity of the specification of the intention with the imprecise information, bring with it the question of how to understand the Qur’ān in each period and society. The issue that has been questioned in the frame of (...) the commentary from the earliest periods is based on the possibility of commenting besides the narration and defining the area that the thought belongs to the commentator. In this context, it is seen that the distinction between the conceptualization of tafsīr-taʾwīl words in classical commentary literature deals with the subject of the tafsīr, their belongings, epistemological values and contexts. Mainly, this study will question whether authors who do not distinguish between tafsīr-taʾwīl categorize the information about commentary in a different context, then it will analyze two basic approaches on tafsīr and taʾwīl. In the paper, it will be suggested that these classifications in the classical literature should be evaluated together within the framework of the search for methodology in exegesis. Summary: The Prophet, who was the first glossator of the Qur’ān, forbade people to talk about the Qur’ān with their own judgments. The prominent people of the companions refused to comment on some words that were closed in meaning (garīb). The words quoted from Abū Bakr and ʿUmar on this subject are quite famous. However, the Qur’ān is a universal book revealed to be understood in all ages and geographies till the doomsday. The fact that all the verses were not interpreted by the Prophet, and the expansions of meaning observed in the Qur’ān wording necessitate the interpretation of the Qur’ān. The fact that the Prophet forbade people to talk with their own judgments about the Qur’ān and the necessity of understanding the Qur’ān in every era constitutes a dilemma that must be explained. The resolution of this issue will both determine the legitimacy of tafsīr (interpretation) and reveal the difference between the Prophet's tafsīr and the tafsīrs by other people. In this context, a distinction was made between the interpretations of the Prophet and of the companions who witnessed the revelation period from the Tabarī (d. 310/923) in the classical tafsīr literature and the interpretations by glossators in terms of their bindingness and information values. Thus, before even starting the interpretation, glossators questioned the possibility of interpretation of the Qur’ān without the tafsīr of the Prophet and the narratives from the companions that have the force of hadith marfūʿ.It is seen in classical tafsīr literature that distinctions between the tafsīr of the Prophet and the interpretations of the glossator are usually constructed on the terms of tafsīr and ta'wil, to which terminological meanings are attributed. In this regard, the methodology of Māturīdī (d. 333/944) is quite specific and clear. According to Māturīdī, tafsīr is an exact field. Only the tafsīr of the Prophet and the narratives of the companions that have the force of marfūʿ can be included in this field. Taʾwīl, on the other hand, is an area based on supposing. Preferences to be made from possible meanings are supposition and related to taʾwīl. The fact that Māturīdī included the explanations of the Prophet and his companions in the tafsīr field and stated that they expressed exact information shows that he regarded this information in the value of the statement of mutakallim. The data included in the field of taʾwīl are not as the data included in the field of tafsīr in terms of their bindingness and information value. The interpretations made in the field of taʾwīl include supposition; so they cannot be attributed to the desire of God. The field that the Prophet forbade people from declaring their own views is the field of tafsīr in the methodology of Māturīdī. The exactness of this field is an indication that the tafsīr is related to God's desire. It is not right to declare an opinion with supposition in the field that is exact and definite. Even though the interpretation in the field of tafsīr is in accordance with the truth, this cannot eliminate the responsibility of the interpreter that make determinations based on supposition in the exact and definite field. Some scholars, such as Qushayrī (d. 465/1072), also classify the narrative-sagacity areas by means of tafsīr-taʾwīl concepts. This classification deals with the data that is the subject of tafsīr in terms of their belongingness. Indeed, tafsīr science includes both the data that are linked with transmission and non-transmittable elements that can be achieved by following a methodology. Non-transmittable elements included in the taʾwīl field by those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity are the meanings reached through linguistic efforts. Language is an element that holds possibilities in itself. Considering closeness of meaning, multi-meanings, metaphors and allusions in the wording, it can be thought that the meanings reached by linguistic methods include supposition. In the methodology of Māturīdī, the field of tafsīr is composed of the explanations of the Prophet and the narratives of the companions who witnessed the revelations while in the classifications of those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity, tafsīr generally includes narratives. When the issue is handled within the framework of the desire of God and the statements of the mutakallim, it seems that the classification of Māturīdī is more punctual. However, it is understood that this approach does not give a satisfactory answer to the subsequent situations and bindingness of the mentioned data. In the classifications based on narrative-sagacity, the narratives in the field of tafsīr are taken as a whole without analyzing their health grades and their signification. However, some of these narrations are not authentic; so, in this respect it is a problematic issue that they are the subjects of the field of tafsīr. Besides, sometimes there can be different narrations about the tafsīr of verses from the companions. The evaluation these narratives in a field attributed to the desire of God may also pose a problem. The linguistic data that both Māturīdī and those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity include in the field of taʾwīl does not appear to have a homogeneous structure -as is the case with the narratives-. Indeed, among this data, there are elements whose meanings are quite hard to determine as well as firm ones that possibly have only one meaning. It is controversial that these expressions, which have only one meaning and to the validity of whose meaning other evidence point out are included in the field of taʾwīl.The distinction between meaning and interpretation fields in tafsīr is very important in terms of tafsīr methodology. This field designation is in a way a description of nature of the science of tafsīr. Thus, in matters where the human intelligence remains insufficient with the tafsīr narratives from the Prophet, the bindingness of the narratives from the companions are clarified; furthermore, beyond the narrative, the validity and the information values of interpretations of the glossator are determined. In this regard, the tafsīr-taʾwīl distinctions made in the classical tafsīr literature provide us with a rich content and a multifaceted point of view. However, when addressed separately, these distinctions present a number of problems in terms of scope and applicability. Our study proposes the evaluation of tafsīr-taʾwīl distinctions in classical literature together while the meaning-interpretation fields are specified in the framework of the search for methodology in tafsīr. Thus, the incomplete aspects of the classification will be eliminated and a much more comprehensive and functional classification will be achieved. At this point, the methodologies of some figures as Tabarī, who is known to have used the terms of tafsīr and taʾwīl in the same meaning, must also be evaluated separately. Indeed, when the works of these names are analyzed, it is seen that these names also distinguish the meaning-interpretation fields in tafsīr, but they do not do this through the tafsīr-taʾwīl concepts.

In healthcare broadly, and especially in genetic medicine, there is an ongoing debate about whether patients have a right not to know information about their own health. The extensive literature on this topic is characterised by a range of different understandings of what it means to have a RNTK,1–9 and how this purported right relates to patient autonomy. Ben Davies considers whether obligations not to place avoidable burdens on a publicly funded healthcare system might form the basis for an (...) obligation to acquire relevant health information, and hence refute the RNTK. He also makes the interesting argument that an obligation to know does not necessarily limit the RNTK. Davies summarises the more prominent arguments against the RNTK, including harm-to-others arguments that focus on potential harms to individuals related to the patient. However he then considers the RNTK in the context of the obligations that people have to each other within a publicly funded healthcare system. So rather than focusing on harms to specific individuals, Davies’ argument is instead based on the wrong of needlessly consuming public healthcare resources. If a person avoids health-related information and thereby exacerbates their health problems, this makes them more complex and expensive to treat. Davies argues that this constitutes …. (shrink)

An axiomatic basis for a social preference ordering with interval-scaled utility levels satisfying the principles of anonymity and pareto superiority is elaborated. The ordering is required to be sensitive to distributional equality: Redistribution of utility income from poor to rich persons without changing their social rank should lead to a superior evaluation. The axiom of separability is weakened in order to make it compatible with distributional equality. We prove that every continuous ordering satisfying the upper axioms can be represented (...) by a utility function which is positively linear on the convex cone of rank-ordered utility vectors. A modified unnormalized Gini coefficient is one possible choice, but it contradicts, as well as related proposals, the principle of adequacy of means for some distribution problems. (shrink)

This book is designed primarily to provide readings for a consideration of the moral issues in medicine from a philosophical point of view. There are two basic alternatives in structuring a philosophical course in medical ethics. One is to divide the course according to medically conceived topics such as organ transplantation, genetic engineering, euthanasie, etc. Such an approach is wholly viable, but we have preferred no to adopt it here. Rather, we have organized the book primarily on the (...) class='Hi'>basis of more philosophically inspired categories. Thus, our headings invoke such notions of paternalism, truth, social justice, etc. (shrink)

Any defense of universal norms involves drawing distinctions among the many things people actually desire. If it is to have any content at all, it will say that some objects of desire are more central than others for political purposes, more indispensable to a human being's quality of life. Any wise such approach will go even further, holding that some existing preferences are actually bad bases for social policy. The list of Central Human Capabilities that forms the core of my (...) political project contains many functions that many people over the ages have preferred not to grant to women, either not at all, or not on a basis of equality. To insist on their centrality is thus to go against preferences that have considerable depth and breadth in traditions of male power. Moreover, the list contains many items that women over the ages have not wanted for themselves, and some that even today many women do not pursue – so in putting the list at the center of a normative political project aimed at providing the philosophical underpinning for basic political principles, we are going against not just other people's preferences about women, but, more controversially, against many preferences (or so it seems) of women about themselves and their lives. To some extent, my approach, like Sen's, avoids these problems of paternalism by insisting that the political goal is capability, not actual functioning, and by dwelling on the central importance of choice as a good. But the notion of choice and practical reason used in the list is a normative notion, emphasizing the critical activity of reason in a way that does not reflect the actual use of reason in many lives.

Decoherence results from the dissipative interaction between a quantum system and its environment. As the system and environment become entangled, the reduced density operator describing the system "decoheres" into a mixture (with the interference terms damped out). This formal result prompts some to exclaim that the measurement problem is solved. I will scrutinize this claim by examining how modal and relative-state interpretations can use decoherence. Although decoherence cannot rescue these interpretations from general metaphysical difficulties, decoherence may help these interpretations (...) to pick out a preferred basis. I will explore whether decoherence solves nagging technical problems associated with selecting a preferred basis. (shrink)

This approach, which is complementary to existing ones, allows to rank-order produced alerts on the basis of a security operator knowledge about the (...) system, used IDS and his preferences about alerts that he wants to analyze or to ignore. Our approach is based on the development of a new non-classical logic for representing preferences, called FO-MQCL (First Order - Minimal Qualitative Choice Logic).

The intra-school controversies in Hanafī school are remarkable. These controversies pose a risk for legal safety and stability and creates difficulties for muqallīd Hanafī judges and muftīs. In the historical process, different types of literature such as mukhtaṣar and fatwa (legal opinion) books, and applications such as aṣṣaḥ-ı aqvāl and maʻrūdhāt, emerged to solve this problem. One of the last example of these applications is the codification movement. The subject of this study is the relationship between the Majalla al-Aḥkām (...) al-ʿAdliyyah, which is the first product of codification based on fiqh (Islamic jurisprudence), and the intra-school preference. In order to describe this relationship, it is briefly emphasized that one of the aims of codification of Majalla is to satisfy the need for intra-school preference. The function and content of Majallaʼs necessary reasons, (asbāb al-mūjiba) was analyzed in terms of intra-school preference. The interventions on the preferences of the Majalla Commission are also emphasized. The Majalla is a text of the intra-school preference. The analysis of its content in relation to intra-school preference is very important. Therefore, in order to reveal what kind of method is used in intra-school preferences and to determine different aspects of intra-school preference in the Majalla, the chapter about ‘sale’ (Kitāb al-Buyūʿ) of the Majalla are examined.Summary: The intra-school controversies in Hanafī School, which is quite important in terms of freedom of ijtihād (independent legal judgment) and legal wealth, possible to threaten legal safety and stability. These controversies also make difficult for judges to reach a judgment or fatwa in controversial affairs. For this reason, determination of the rājiḥ (preferred opinion) in controversial issues in the school, is a need that must be eliminated.The intra-school preference can be described as "to determine the superior, preponderant of different opinion or narrations about a specific issue in the school". In the historical process different types of literature such as mukhtaṣar and fatwa books, and different applications such as asaḥḥ-ı aqvāl and maʻrūzāt, emerged to meet this need. One of the applications aimed to meet this need is the codifications in the last period of the Ottoman State.The relationship between the Majalla al-Ahkam al-Adliyyah, which is the first example of codification based on fiqh (Islamic jurisprudence), and the intra-school preference; and in this context, while preparing the Majalla how a method was followed in the intra-school preference; at what rate be obeyed the rājiḥ (preferred) opinion; articles contrary to the rājiḥ (preferred) opinion in Majalla and their reasons; whether legal arrangements have been made in all controversial issues; at what rate be met the need of determination of rājiḥ (preferred) opinion are the issues that need to be examined.One of the main reasons for the need for a law text such as Majalla al-Ahkam al-Adliyyah is the multitude of the intra-school controversies in Hanafī School. Therefore, the goal of Majalla is to prepare a code that contains rājiḥ opinion.When Majallaʼs necessary reasons, i.e. asbāb al-mūjiba, are examined in terms of the intra-school preference, it is seen that there are two basic functions of necessary reasons. The first of them is, emphasizing that the code is prepared substantially in accordance with the râjih opinion in the school. In fact, that this issue in the asbāb al-mūjiba of the first ten books of Majalla is expressly stated. The other function of the asbāb al-mūjiba is to justify that why rājiḥ opinion are not be confirmed in some article. In the necessary reasons it is stated that twelve articles are prepared in the direction of unrâcih (unpreferable) opinion. Considering that Majalla is formed of 1851 article, it will be better understood that how the rājiḥ opinions are effective in Majalla's content. Essentially, the conditions of the period also make it necessary. The preference of the non-preferred opinion of Züfer (d. 158/775) in 692nd article of Kitāb al-Ḥavala, caused the reaction of some circles mainly Şeyhülislam Hasan Fehmi Efendi (d.1298/1881) and for this reason Ahmet Cevdet Pasa (d.1895) was dismissed from the ministry of Divan al-Ahkâm al-Adliyyah and the chairman of the Majalla Commission.When the asbāb al-mūjibas of contrary articles to rājiḥ opinions are examined, it is seen that maṣlaḥa and customs are determinative in these preferences. It is also seen that the preferences of some jurists are also mentioned as a reason of preference. The most widespread preference’s reason in Hanafī sources is in congruity with the texts. On the contrary, it is noteworthy that, besides the interdiction of extravagant (safih), it is not operated as a preference’s reason in Majalla.Some preferences of the Majalla Commission were intervened by other institutions. The chapters prepared by the commission were examined both by Majlis-i Wukalā and Mashihat, and these chapters were subject to some revisions at this time. Here, two articles prepared on the basis of the non-preferred opinion were intervened by Majlis-i Wukalā. The first of these is 216th article that written in the direction of opinion of Mashāyikh Balkh, which argues that it is permissible to sell separately ḥaqq al-murūr (the right of passage) and ḥaqq al-shirb (water right), the second is the 611th article which regulates the liability to damage of ajīr al-mushtarak (joint salaried employee).When the content of Kitāb al-Buyū, the first and the most voluminous book of Majalla, is examined in terms of the intra-school preference, it is seen that the rājiḥ opinions in the school are generally taken as basis. It is stated that in the asbāb al-mūjiba of the Kitāb al-Buyūʿ the four issues are prepared basing on the non-preferred opinion and these preferences are justified with custom and maṣlaḥa. However, the contrary articles to the rājiḥ opinion in the Kitāb al-Buyūʿ are not limited to these. According to our research, in addition to these, three articles were prepared with the preference of non-preferred opinion. These are the 118th article regarding that the bayʻ bi-l-wafā is permissible in chattels, 165th article on the definition of al-ghabn al-faḥiş (lesion), and the 309th article concerning the provision of the khiyār al-sharṭ (right of cancellation). These three articles show that the regulations contrary to the rājiḥ opinion in Majalla are not just those explained in the asbāb al-mūjiba and this situation is contrary to the method that is followed when preparing the Majalla.In some controversial issues in the Hanafi School, authorized jurists to preference (asḥāb al-tarjīh) disagreed over which opinion is rājiḥ. It wasn’t explained that how a method would be followed in Majalla when the legal arrangements were made in these matters. When these issues are examined, it can be said that the preferences of the majority, the providing of convenience and the preference by some jurists are effective.Preferences in Majalla have not been occurred only among the sharʻī (related to Islamic Law) provisions. In addition, the definitions and the inscription in the definitions are also the subject of preference. In this context, the preferences related to the definition of the sales contract, the suspended contract (al-ʻaqd al-maqqūf) and the al-ghabn al-faḥiş in Kitāb al-Buyūʿ can be mentioned as an example.Some controversial issues in the Hanafi School are not regulated in Majalla. When considering the multiplicity of controversial issues and therefore the difficulty of making legal arrangements to cover all of them, this situation is natural. Moreover, some of these issues may not have been regulated in Majalla because they are not frequent and necessary. However, it is not possible to explain all the controversial issues that have not been regulated for these reasons. Because some of the controversial issues that have not been legislated are basic, relatively important issues and they are included in the mukhtaṣars. This indicates that when preparing the Majalla, instead of making preference on some controversial issues, the method of non-regulation of these matters is adopted. It can be said that this method is applied as a way of creating law text which is clear of controversy. Thus, the determining of the rājiḥ opinion in these matters has been left to the judges. This situation is not suitable to meet the need of determining the rājiḥ opinion, which is the goal of Majalla. But it is the result of the difficulty of making a law that encompasses all legal issues. (shrink)

If moral epistemology can be naturalized, there must be genuine moral knowledge, knowledge of what it is morally right for someone or even everyone to do in a particular situation. The naturalist hopes to explain how such knowledge can be acquired by ordinary empirical means, without appealing to a special realm of moral facts separate from the rest of nature, and a special faculty equipped to detect them. Various learning mechanisms for acquiring moral knowledge have been proposed. Most, however, have (...) the following deficiency: What they actually explain is moral acculturation with respect to accepted or author-preferred moral norms, not the acquisition of moral knowledge. Of course, an additional premise to the effect that accepted moral norms or author-preferred norms embody moral truths would deal nicely with this problem, but at the expense of the distinction between opinion and knowledge, or true belief, in which epistemologists are necessarily interested.

How can we establish a political/legal order that in principle does not require the human flourishing of any person or group to be given structured preference over that of any other? Addressing this question as the central problem of political philosophy,_ Norms of Liberty_ offers a new conceptual foundation for political liberalism that takes protecting liberty, understood in terms of individual negative rights, as the primary aim of the political/legal order. Rasmussen and Den Uyl argue for construing individual rights (...) as metanormative principles, directly tied to politics, that are used to establish the political/ legal conditions under which full moral conduct can take place. These they distinguish from normative principles, used to provide guidance for moral conduct within the ambit of normative ethics. This crucial distinction allows them to develop liberalism as a metanormative theory, not a guide for moral conduct. The moral universe need not be minimized or morality grounded in sentiment or contracts to support liberalism, they show. Rather, liberalism can be supported, and many of its internal tensions avoided, with an ethical framework of Aristotelian inspiration—one that understands human flourishing to be an objective, inclusive, individualized, agent-relative, social, and self-directed activity.

Instead of speaking of conscious experience as arising in a brain, we prefer to speak of a brain as arising in conscious experience. From an epistemological standpoint, starting from direct experiences strikes us as more justified. As a first option, we reconsider the ‘hard problem’ of the relation between conscious experience and the physical world by thus turning that problem upside down. We also consider a second option: turning the hard problem sideways. Rather than starting with the (...) third-person approach used in physics, or the first- person approach of starting with individual conscious experience, we consider starting from an I-and-you basis, centered around the second-person. Finally, we present a candidate for what could be considered to underlie conscious experience: ‘sense’. We consider this to be a shot in the dark, but at least a shot in the right direction: somewhere between upside down and sideways. Our notion of sense can be seen as an alternative to panpsychism. To give an analogy, using the notions of space and time is more convenient than trying to analyse the phenomenon of motion in terms of a space-based ‘pandynamism’. Similarly, when approaching the phenomenon of consciousness, we prefer the triad of space, time and sense, over a spacetime-based form of panpsychism. (shrink)

1.1 The Concept of Evil The problem of evil, in the sense relevant here, concerns the question of the reasonableness of believing in the existence of a deity with certain characteristics. In most discussions, the deity is God, understood as an omnipotent, omniscient, and morally perfect person. But the problem of evil also arises, as Hume saw very clearly, for deities that are less than all-powerful, less than all-knowing, and less than morally perfect. What is the relevant concept (...) of evil, in this context? Here it is useful to distinguish between axiological concepts and deontological ones. First, there are judgments about whether certain states of affairs make the world better or worse, whether those states are good or bad, desirable or undesirable. Such normative concepts – of good and bad, or desirable and undesirable, states of affairs – are axiological concepts. Secondly, there are judgments about the rightness and wrongness of actions, about what one morally ought or ought not do, of what one’s duty is, of whether a certain action violates someone rights, and these concepts – of the rightness and wrongness of actions, of duties, of the rights of individuals, of what one should or should not do – are deontological concepts. Given this distinction, should the problem of evil be understood axiologically or deontologically? Often, and I think most commonly in this context, evils are equated with states of affairs that, all things considered, are bad or undesirable: they are states of affairs that make the world a worse place. But one can also interpret the problem of evil in a deontological fashion, equating evils with states of affairs that a person should have prevented, if he could have done so. Elsewhere (2008, 105-6), I have argued that the deontological interpretation is preferable. But for present purposes, either interpretation will be fine. 1.2 Evil and the Reasonableness of Belief in the Existence of God That many things in the world – tsunamis, earthquakes, the suffering of non-human animals and innocent children, human actions such as the carrying out of the Holocaust – certainly appear to be evil is not a controversial matter. But whether such things are really evils, all things considered, is disputed. Assume, however, that the world does continue genuine evils, and not merely apparent ones. How, then does the existence of such evils bear upon the reasonableness of belief in the existence of God? First, the existence of evils can be used to show that certain arguments for the existence of God cannot establish that conclusion, or even render it probable. For some arguments, of course, one need not appeal to evil to make that point. If someone argues for the existence of a first cause, or an unmoved mover, or a necessary being having its necessity of itself, and then claims that this is what everyone understands by the term “God”, one can point out that no reason has been offered for thinking that the entity in question is even a person, let alone omnipotent, omniscient, and perfectly good. By contrast, with the type of argument that Hume was concerned with when he discussed the problem of evil – namely, arguments from the existence of order in the world to the existence of a designer, or intelligent cause of that order – one does have a type of argument that, if sound, shows that there is a person who, even if not omnipotent and omniscient, is at least extremely powerful and very knowledgeable. But such arguments do not support for conclusions about the moral character of such a person, and so it is at this point that the existence of evils becomes crucial. For in providing a reason for holding that the one is not justified in attributing even moral goodness to such a being, let alone moral perfection, it supports the conclusion that that argument in question cannot be a successful argument for the existence of God. The existence of evils, then, can serve to block arguments for the existence of God. But a second, and very familiar possibility, is that the existence of evils can also provide the basis of arguments against the existence of God. A very important distinction here is between deductive, or logical incompatibility, versions of the argument from evil, and inductive, or evidential, or probabilistic versions of the argument. According to the former, there are facts about the existence of evils in the world that are logically incompatible with the existence of God. Thus, some have held that the mere existence of any evil whatsoever is incompatible with the existence of God; others, that that certain types of evil – such as natural evils – are incompatible with the existence of God; and others, that it is the amount of evil in the world, or the fact that some people suffer horrendous evils, that logically precludes the existence of God. Inductive (or evidential, or probabilistic) versions of the argument from evil, by contrast, do not claim that there are facts about the evils in the world that are logically incompatible with the existence of God. The claim is rather that there are facts about the evils found in the world that render the existence of God at the very least unlikely, and perhaps extremely so. 1.3 Hume’s Use of the Existence of Evils The preceding discussion suggests two very different ways in which Hume might be employing the existence of evils. First, he might be appealing to the existence of evils simply to undercut certain arguments for the existence of God. In particular, he might be appealing to evils to show that, whatever the merits of the argument from order to design may be, it can nether establish, nor render probable, the existence of a morally good deity. Secondly, Hume might be advancing a version of the argument from evil, and that in turn could take the form either of an argument that claims that facts about evil are logically incompatible with the existence of God, or of an argument that claims, more modestly, that the apparent evils found in the world render the existence of God unlikely.

This thesis challenges prevailing approaches to religiously-based or influenced laws , and proposes an alternative model that makes religious pluralism, gender, and moral identity central considerations. I focus my analysis around abortion as a case study in order to analyze the gendered dimensions of the issue in addition to other, more well-recognized problems with religious lawmaking. ;My overarching thesis is that the prevalent approaches to religious lawmaking in the Supreme Court's jurisprudence, as well as in liberal and communitarian moral and (...) legal theory, are inadequate. Liberal approaches tend to protect religious pluralism at the expense of the religious identity of lawmakers, whereas communitarian proposals protect the religious morality of lawmakers at the expense of respect for religious pluralism. Both approaches are also inadequate, I contend, because they are premised upon faulty conceptions of moral identity, and fail to adequately consider the potential of religious lawmaking to perpetuate inequalities based on gender as well as religion. My arguments regarding deficiencies in these approaches are reinforced with empirical evidence regarding abortion views held by American religious groups, as well as the self-descriptions of a number of lawmakers regarding the influence of religion in their decision making. ;In developing alternative ethical and legal frameworks for addressing religious lawmaking, my analysis proceeds along both theoretical and practical lines. On the theoretical level, I propose that the conceptions of the social self and role-based morality developed by the twentieth century pragmatist philosopher George Herbert Mead, as supplemented by feminist and poststructuralist perspectives, provide the basis for a preferable ethical approach to religious lawmaking. ;On the practical level, I develop a legal framework that requires government in qualified challenges to religious lawmaking to show that the law can be fully supported on the basis of publicly accessible reasons and, in some instances, also by a compelling state interest. I explain how this proposal can accommodate the interests of religious lawmakers in relying on their religious convictions in their political and legal decision making, while insuring that the citizenship rights of their constituents are not thereby harmed.

This article discusses the issue of arrangement /ordering of compulsory-comprehensive maqāsid. In this respect, the main purpose is to help clarify the ordering problem. To accomplish this task, the classical and contemporary studies on this subject were reviewed. Within the scope of this research, it has been determined that the universal principles are generally listed in the order of religion, nafs, mind, generation and property. However, alternative orderings can be found where the nafs is placed at the forefront. The (...) focal point of the ordering problem is emerges from the question of whether Allah's rights/otherworldly maqāsid should be priorities or servants' rights/worldly maqāsid. The conflict between religion, which is an otherworldly value, and other principles played an active role in this classification of maqāsid. Many legal scholars who placed religion in the first place in the classical period did not clearly explained the justification of their arrangement. Also, many of today's researchers also stated that religion should come first. The scholars who put both the religion and the nafs in the center have listed many evidence for their preference. The legal scholars who put religion at the center have pointed the verse " I have not created the jinn and men but they may worship Me" as the basis for their views. Accordingly, the main purpose of the creation of human being is to serve Allah. Because the most important right to be fulfilled is the right of Allah religion should take precedence over other virtues in maqasid. Religion is also the only essential way that leads to eternal happiness. According to the legal scholars who put religion into the center, other maqasid principles are secondary. Correlatively, other principles serve religion. The hadith "The debt to Allah is more worthy of being paid." has been made the basis. Since religion constitutes the essence of the maqāsid, it is also a requirement of reason to make religion essential. According to another reason they stated, the obligation of jihad also ensures that religion is at the center. The obligation of jihad causes lives to be sacrificed to protect the religion. This means that religion is superior to the nafs and other principles. Because jihad, which is the order of religion, is fard. The scholars who maintain that the rights of the servants should take precedence over the right of Allah have cited also a lot of evidence. We come across with their views presented as a weak view in the sources or as an answer to a possible question. There is no clear information about to whom these views belong. Therefore, it is stated that no one introduces the nafs to religion. As a matter of fact, it is stated that it is not correct to qualify these views as an independent view defended by scholars. In other words, the view putting the nafs at the center and the evidence to this preference at this point should be regarded as hypothetical. We are of the view that these claims of contemporary writers need to be proven. The basic reason of the views that puts the nafs in the center is based on the pre-acceptance that maslahahs like the nafs are the right of servants while religion is the right of Allah. The given reasons can be addressed under three main headings: punishments, mitigation of prayers, and concern with non-Muslims. In case where the rights of the servant and Allah unite, the rights of the servant should be preferred. Because, the rights of servants are on hardship, and the rights of Allah are on breadth and mercy. On the contrary to the rights of the servants, postponing or neglecting the right of Allah will not harm Allah. It is clear that if the rights of the servants face postponement, they will suffer serious damage. The fact that killing a man who both abandoned his religion and killed someone unfairly, not for his departure from religion, but for retaliation, that is, the right of a servant, is a concrete example of this. The shortening of the prayer during the journey, the patient’s abandoning standing in prayer and the fasting, and other examples also require the human to be in the center. Today, there are researchers who take the nafs to the center. The existence of religion for humans and society reflects the view of these researchers. Because it is clear that religion will remain dysfunctional where there is no human and society. When these evidences are examined carefully, it can be concluded that the opinion that defends the nafs to be at the center of comprehensive maqāsid is preferable. (shrink)

Duncan Pritchard has defended a version of epistemological disjunctivism which holds that in a paradigmatic case of perceptual knowledge, one knows that \ in virtue of having the reflectively accessible reason that one sees that \. This view faces what is known as the basis problem: if seeing that \ just is a way of knowing that \, then that one sees that \ cannot constitute the rational basis in virtue of which one knows that \. To (...) solve this problem, Pritchard has argued that seeing that \ should be reduced to being in a good position to know that \ rather than simply knowing that \. I argue that this proposal can only be properly understood if the concept of knowledge is taken as primitive, and is supported by an example that either fails to favor it over the alternative, or else backfires against the proposal itself. This leaves the new account of seeing that \ unmotivated, thereby challenging the purported answer to the basis problem. (shrink)

Going back at least to Duhem, there is a tradition of thinking that crucial experiments are impossible in science. I analyse Duhem's arguments and show that they are based on the excessively strong assumption that only deductive reasoning is permissible in experimental science. This opens the possibility that some principle of inductive inference could provide a sufficient reason for preferring one among a group of hypotheses on the basis of an appropriately controlled experiment. To be sure, there are analogues (...) to Duhem's problems that pertain to inductive inference. Using a famous experiment from the history of molecular biology as an example, I show that an experimentalist version of inference to the best explanation (IBE) does a better job in handling these problems than other accounts of scientific inference. Furthermore, I introduce a concept of experimental mechanism and show that it can guide inferences from data within an IBE-based framework for induction. 1. Introduction2.

In the many worlds community there seems to exist a belief that the physics of quantum theory is completely defined by it’s Hamilton operator given in an abstract Hilbert space, especially that the position basis may be derived from it as preferred using decoherence techniques.We show, by an explicit example of non-uniqueness, taken from the theory of the KdV equation, that the Hamilton operator alone is not sufficient to fix the physics. We need the canonical operators $\hat{p}$ , (...) $\hat{q}$ as well. As a consequence, it is not possible to derive a “preferred basis” from the Hamilton operator alone, without postulating some additional structure like a “decomposition into systems”. We argue that this makes such a derivation useless for fundamental physics. (shrink)

India dropped its target of 500 GW of renewable energy capacity fossil fuel sources by 2030. Its responsibilities the United Nations Framework Convention Climate Change [UNFCCC],and reducing radiations by one billion tonnes by the end of the decade at the COP26 conference, held in Glasgow in November 2022. Researchers are continually searching for inexhaustible and reasonable energy sources. Solar energy is one of the greenest sources of energy and is also one of the cleanest. The most important factor in using (...) solar energy is the location of the solar power plant. The main objective of this study is to find the best location for a new solar power plant in a specific region called Bundelkhand region of Uttar Pradesh in India. Here we offer an extension of ELECTRE III method as two-phase Pythagorean neutrosophic elimination and choice translating reality PN-ELECTRE-III) method to adapt with fuzzy, ambiguous, unsure, and indeterminate criteria. The Pythagorean neutrosophic numbers [PNNs] used by the group decision support system of PN-ELECTRE III to measure performance of the alternatives. The options are entirely outclassed in the subsequent stage in view of the past stage's evaluations of them. By defining PNN we describe the technique of indifference threshold functions, preference treshold and veto threshold functions, which provide a more stable basis to drop outranking relations. By calculating the concordance credibility, discordance credibility and net credibility degrees of each alternative, the ranking module of the PN-ELECTRE III approach is made simpler. In order to confirm the applicability of the strategy suggested in this paper, the location selection problem for solar plants is finaly solved. (shrink)

In a familiar interpretation, the Non-Identity Problem claims that persons whose existence depends on a seemingly harmful action cannot in fact be harmed through such an action. It is often objected that the persons in question can nevertheless be wronged through a violation of their rights. However, this objection seems to fail because these persons would readily waive any violated right in order to come into existence. The present article will analyze this Waiver Counter Argument in detail and show (...) why it does not succeed. First, it is necessary to distinguish between a prospective and a retrospective waiver scenario. In the prospective scenario an imagined person must consider whether she wants to waive a right in order to come into existence. In the retrospective scenario a person is asked whether she would prefer a wronged existence to never having been born. In both scenarios the conditions of a legitimate waiver of rights are not met, but for different reasons. On this basis, an argument against NIP can be developed. (shrink)

This paper is concerned with Spinoza’s treatment of a problem in early modern moral philosophy: the potential conflict between the pursuit of happiness and virtue. The problem is that people are thought to attain happiness by pursuing their self-interest, whereas virtue requires them to act with benevolence, for the benefit of others. Given the inevitability that people will have different and often competing interests, how can they be both virtuous and happy and, where the two are in conflict, (...) which should they prefer? While there were an array of treatments of the problem, most agreed on the general strategy of arguing that people’s true interests—as revealed through reason—are not in competition; rather, they coincide, such that promoting the interests of others promotes people’s own interests and vice versa. Such a response aims to show that people’s happiness is best served by being virtuous and their virtue is best served by making themselves happy.Spinoza agreed with the general outline of this solution, equating virtue with power, thereby defining virtuous behavior as the pursuit of one’s own interests. Since, for Spinoza, happiness arises from increasing one’s power, happiness and virtue are necessarily connected. Furthermore, he does not equate virtue and happiness at the expense of benevolence. This point may be overlooked since Spinoza’s single comment in the Ethics on benevolentia is denigrating: he defines benevolence as a desire arising from pity and “in a man who lives under the guidance of reason, pity in itself is useless and bad” . 1 However, we should distinguish Spinoza’s benevolentia, a kind of piteous desire, from a common notion of benevolence as acting to the benefit of others, which he defends.

Epistemological disjunctivism argues that one can have perceptual knowledge that p in virtue of being in possession of factive and reflectively accessible rational support, e.g., one’s ‘seeing that p’. A well-known challenge to this view is the so-called basis problem of epistemological disjunctivism, which argues that one’s ‘seeing that p’ cannot constitute the rational support for one’s knowledge that p, as ‘seeing that p’ is just a way of ‘knowing that p’. The basis problem is taken (...) to be based on the entailment thesis, viz, ‘seeing that p’ entails ‘knowing that p’. Mainstream solutions to the basis problem take an approach rejecting the entailment thesis. This paper purports to reveal a common defect of those extant solutions. That is, they all fail to address the basis problem in the central domain of discussion of epistemological disjunctivism, i.e., what Pritchard refers to as ‘paradigmatic cases’. Moreover, even if they succeed in rejecting the entailment thesis in paradigmatic cases, they would also backfire on epistemological disjunctivism. (shrink)

Some claim slavery did not harm the descendants of slaves since, without slavery, its descendants would never have been born and a life worth living, even one including the subsequent harms of past slavery, is preferable to never having been born at all. This creates a classic puzzle known as the non-identity argument, applied to reject the validity of claims for historic justice based on harms to descendants of victims of historic wrongs: since descendants are never harmed by historic wrongs, (...) they have no right to rectification. This conclusion is unintuitive. This article explains the nature of harm involved in historic injustice, overcoming the hurdle the non-identity argument poses to historic justice claims. Historic injustice and the harms it generates are best understood as group harms. Claims for historic justice can be grounded in harms currently living individuals suffer as a function of the harms their group or community currently suffers as a consequence of historic wrongs. One form of harm, constitutive harm, differs from the aggregative account of harm assumed by the non-identity argument and is immune to it. It is the type of harm people suffer as members of certain historically wronged groups and communities. Therefore, the constitutive harm people suffer in cases of historic injustice may serve as a basis for justifying claims for historic justice. (shrink)

The main subject of this paper is the two significant problems of environmental ethics which are ecofascism and speciesism. This scrutiny offers an evaluative perspective on the main problems of environmental ethics and is conducted with this aim. Most of the environmental philosophers, all the difficulties notwithstanding, try to find a middle way in the ecofascism-speciesism continuum and their theories get closer to one or the other edge of this continuum. John Baird Callicott is one of the environmental philosophers who (...) struggle with this issue when his theory indicates one of the problems or gets closer to one of the edges, he tries to find a new way to go. There are six turns in Callicott's philosophy starting with strong holism due to accepting Leopold's land ethic as a basis. Then, he constructed a theory that pushes him closer to the speciesist edge, and finally, he found a way out from these fatal consequences. However, all the environmental philosophers face the same problems in their journey although they are either holists or individualists in the end. In constructing a holistic environmental ethical theory, for instance, they may be in ecofascism difficulty because holism requires man to be an ordinary member of the biotic community as seen in the first turn. Or, establishing a special place for humankind to ditch the ecofascism crisis may cause another equally important crisis, namely, speciesism (see the third turn). Some philosophers prefer to be closer to one of the edges always being on guard against the other. Some others, like Callicott, try to find a middle way equally far from the edges. However, this choice is no easier. Selecting to be a member of both the human community and biotic community brings different problems, such as ranking problems between the duties and obligations toward the communities and their members, i.e. a challenge to decision-making processes. For such problems, they come up with some principles or rules like second-order principles (SOPs) as Callicott did (in the fifth turn). But, these rules or principles are not sufficient enough to solve the ranking problems of setting priorities among our duties to members of both communities, either. Thus, either there is a need for more regulations and rules, or these two communities should be separated in a different dimension and gathered at another level. The second choice is preferred by Callicott and used as a solution to the main problem: constructing an environmental ethical theory that involves whole nature with its members and which is free from two essential problems (see the sixth turn). As a final point, Callicott's last theory seems to point to the conclusion that an environmental ethical theory is possible without falling into the ecofascism and speciesism traps, i.e. his last stand can facilitate the attainment of the main subject of this essay.

An account is given of the work on glacial phenomena in the English Lake District from the time of Adam Sedgwick until the mid-twentieth century, with emphasis on the nineteenth century. In the early years, the following theories were envisaged: 'diluvialism'; the theory of 'waves of translation'; the theory of 'ice rafting'; the 'glacial-submergence' hypothesis ; and the 'land-ice' theory. While it was quite easy to recognize ice action and the former existence of glaciers, it was difficult to work out (...) a persuasive sequence of events that would account satisfactorily for the great variety and quantity of evidence available, considering land-forms, and the distribution of moraines, tills, gravels, and glacial erratics. When the first systematic geological survey was being undertaken in the Lake District both local amateurs and the surveyors favoured the glacial-submergence theory, but there were problems about explaining the distribution of glacial erratics, and controversy developed as to whether this distribution was best explained in terms of floating icebergs or landice. The problem was difficult in that there was uncertainty as to how many glaciations there had been, though the preferred number was two, following the early observations in Wales by Andrew Ramsay, in Lancashire by Edward Hull and others, and by some Continental geologists, of two different tills, and one intermediate water-deposited unit. These seemed to have equivalents in the Lake District. However, the Scottish surveyors, under the influence of their theorist colleague, James Croll, with his astronomical explanation of ice ages, favoured multiple glaciations. Croll himself sought to apply the land-ice theory to explain the distribution of glacial erratics in the regions round the Lake District. James Geikie read widely in the Continental literature, and thought that the theory of several glaciations, developed by Albrecht Penck in the 1880s, on the basis of observations of the valleys and rivers terraces running north from the Alps, fitted well with Croll's theory. Thus the idea of a sequence of glaciations was applied to Britain with some success, partly as a result of Geikie's advocacy. But the evidence of such a sequence in the Lake District itself was by no means clear, and it was not developed for the region until the work of Frederick Trotter and Sidney Hollingworth . In the meantime, much geomorphological work on the form and formation of lakes and tarns had been done by the chief aficionado of Lakeland geology, Cambridge professor, John Marr. But he thought there might have been only one major glaciation. The paradox is that, for England, the glacial sequence has had to be worked out more by examination of deposits in the flatter southern regions, as much as in the mountains where the glaciers were formed and most active. In the Lakeland mountains, as in other parts of the world, the last glaciation has tended to remove or obscure the products of earlier glaciations. (shrink)

A system of semigroup identities is hereditarily finitely based if it defines a variety all semigroups of which are finitely based.

Relational quantum mechanics (RQM) is an interpretation of quantum mechanics based on the idea that quantum states do not describe an absolute property of a system but rather a relationship between systems. There have recently been some criticisms of RQM pertaining to issues around intersubjectivity. In this article, we show how RQM can address these criticisms by adding a new postulate which requires that all of the information possessed by a certain observer is stored in physical variables of that observer (...) and thus is accessible by measurement to other observers. This makes it possible for observers to reach intersubjective agreement about quantum events that have occurred in the past. We suggest a possible ontology for a version of RQM employing this postulate; this ontology upholds the principle that quantum states are always relational, but it also postulates a set of quantum events that are not strictly relational. We show that the new postulate helps address the preferred basis problem in RQM. (shrink)

Laurence Cooper has offered a wellwritten, carefully argued, thought-provoking account of Rousseaus understanding of the primitive basis for the natural goodness of civil man and the relation between amour de soi and amour-propre. His book exposes a troubling perplexity in Rousseaus work. One might find Rousseaus account of the goodness of the primitive human beings to be a model for psychic unity in all healthy and natural civilized men. But, one could also understand Rousseaus Second Discourse as a thought (...) experiment that shows that distinctively human traits are, in fact, social in origin. Laurence Cooper wants to have it both ways. While self-consciousness is a necessary part of the human condition as we know it, Cooper maintains Rousseaus own ambiguity regarding the humanity of the less than fully human savage man. Unproblematic solitary self-love, amour de soi, defines natural man. Amour-propre, comparative self-preference, develops with sociability and introduces all conflict and corruption. Laurence Cooper examines its potential benefit when redirected into healthy pride or reciprocal affection. (shrink)

I argue that there are good reasons to deny both type-type and token-token mind-brain identity theories. Yet on the other hand there are compelling reasons for thinking that there is a causal basis for the mind. I argue that a path out of this impasse involves not only showing that criteria of individuation do not determine identity, but also that there are sound methodological reasons for thinking that the cause of intelligent behavior is a real natural kind. Finally, a (...) commitment to this methodology suggests both that these familiar anti-reductionist arguments fail to establish that identity is impossible and at the same time suggest that the preferred alternative will be some version of neutral monism.

Stellen Kondome einen potenten Schutz sowohl vor HIV als auch von anderen sexuell übertragbaren Infektionen (STIs) dar, und besteht außerdem ein barrierefreier Zugang zur HIV-Postexpositionsprophylaxe (PEP) (z. B. nach Kondom-Fatigue), muss präzise sondiert werden, wann die sich zunehmend etablierende HIV-Präexpositionsprophylaxe (PrEP) die bessere Wahl darstellt. Vor dem Hintergrund einer generalisierten everyone at risk-Annahme über MSM wird die PrEP zunehmend zu einem standard of care. Zwar kann kein Zweifel daran bestehen, dass dies für bestimmte MSM mit einem bestimmten Risikoprofil wünschenswert ist. (...) Es ist aber von Variabilitäten (z. B. casual condomless sex versus random condomless sex) auszugehen, die zur Vermeidung einer unverhältnismäßigen Medikalisierung berücksichtigt werden müssen. Im Spannungsfeld von hochpotenter HIV-Prävention und Medikalisierung insbesondere von Männern, die Sex mit Männern praktizieren, soll im Sinn einer Güterabwägung gefragt werden, wann genau eine PrEP (dauerhaft oder on demand) mehr Vorteile und weniger Nachteile bietet als der Gebrauch von Kondom oder PEP. Dazu gehört ein Fokus auf den aktuellen Stand der klinischen Forschung und ein Fokus auf die medizinethische Debatte. Die Medizingeschichte der Prävention und der HIV-Erkrankung erweist sich dabei als relevanter Erörterungszusammenhang für die weitgehend noch ausstehende ethische Untersuchung der PrEP. Methodisch basiert diese Arbeit auf einer Auswertung der interdisziplinären Fachliteratur über die HIV-Präexpositionsprophylaxe im Besonderen und über HIV-Prävention im Allgemeinen. Basierend auf den PRISMA (Prefered Reporting Items for Systematic Reviews and Meta-Analyses) Guidelines wurden aus der Datenbank PubMed/MEDLINE solche Studien ausgewählt, die die aktuelle klinische Praxis der PrEP oder eine medizinethische Diskussion der PrEP zum Gegenstand haben. Auf der Basis dieser Literatur erfolgt eine diskursive Erörterung und Abwägung der verfügbaren Pros und Cons zur PrEP. Präventionsmaßnahmen treten regelmäßig als ambivalente Instrumente der Gesundheitsförderung zwischen Liberalisierung und Restringierung des Individuums hervor. Insgesamt bietet daher die PrEP on demand gegenüber der kontinuierlichen PrEP im Sinne der Personalisierung die Option einer individuellen Anpassung an konkretes Risikoverhalten. Auch im Sinne einer Güterabwägung hat die PrEP gewichtige Vorteile gegenüber der kontinuierlichen PrEP und gegenüber einer PEP, wenn kein dauerhaft gleichhohes Risiko vorliegt. In dieser medizinethischen Untersuchung wird darauf hingewiesen, dass es sich bei MSM um eine heterogene Gruppe handelt, deren individuelles Sexualverhalten eine ebenfalls individualisierte HIV-Präventions-Strategie benötigt. Diese Studie argumentiert daher für ein stark personalisiertes decision making bei möglicher Indikation für eine PrEP bei MSM. Damit soll ein wesentlicher Faktor zur Vermeidung einer Medikalisierung von MSM dargestellt werden. (shrink)

Most interpretations of Quantum Mechanics alternative to Copenhagen interpretation try to avoid the dualistic flavor of the latter. One of the basic goals of the former is to avoid the ad hoc introduction of observers and observations as an inevitable presupposition of physics. Non-Copenhagen interpretations usually trust in decoherence as a necessary mechanism to obtain a well-defined, observer-free transition from a unitary quantum description of the universe to classicality. Even though decoherence does not solve the problem of the definite (...) outcomes, it helps to explain why we do not observe superpositions and, according to Zurek’s existential interpretation, why a specific preferred basis emerges through system–environment interactions. The aim of this paper is to show why such interpretation ends up begging the question and provides little progress in understanding the quantum-to-classical transition; the ultimate reason being that preferred bases always correlate to human observation. Benefitting from the technical discussion, some remarks will be offered in the last section regarding the role of classical observations as a necessary condition to make workable the formalism of Quantum Mechanics and scientific activity itself.
