This article reviews the development of a new set of practices within modern medicine that can generally be called “cosmetic medicine,” practices that include cosmetic surgery, cosmetic dermatology, and cosmetic gynecology. I argue that the development of such fields indicates a fundamental change in the practice of medicine. After reviewing the possible explanations proposed for such developments, in order to indicate the social and cultural origin of the driving forces, I discuss the implications of these revolutionary changes for the perceived (...) goal of medicine. Of particular importance is the development of beauty as the main goal in cosmetic medicine. The development of the new fields supports the idea that... (shrink)

A human being is the simultaneous composite of several different levels of being, from atomic and subatomic to the level of complex social interaction, and these levels are nested within the individual hierarchically (lower levels giving rise to higher levels, etc.). One of the most important and influential approaches developed in the history of science has been that of systems theory and systemic thinking, in which the different levels of the hierarchy, and the interactions between those levels, are considered simultaneously. (...) Although this model provides a comprehensive view of biological being, the transition from one level to the other is not well defined in it. Uexküll and Pauli (Advances: Journal of the Institute for 417 the Advancement of Health 3:158–174, 1986) suggested that semiosis is the translator of the events from one level to the other. From a psychological point of view, a myriad of semiotic events happen inside an individual, and it has been suggested that among other semiotic events, inner speech plays an important role in mediating personal agency. Dialogical theories of the self, Jungian psychology and hypnosis research evidence show that there is a semiotic multiplicity in human agency and consciousness, and that these multiple streams are all converge to a central semiotic singularity. I argue in this paper that by taking a biosemiotic point of view, human ‘agency’ may be defined as the ability of an individual to direct the incoming and internal streams of semioses and the ability to create an integrative and superordinate new stream of semiosis in addition to the upwardly and downwardly component ones, and how such a view might open a new door for research into the concept of human ‘personality’ and ‘agency’.

Hopfield neural network is considered as an artificial model derived from the brain structures and it is an important model that admits an adequate performance in neurocomputing. In this article, we solve a dynamical model of 3D HNNs via Atangana–Baleanu fractional derivatives. To find the numerical solution of the considered dynamical model, the well-known Predictor-Corrector method is used. A number of cases are taken by using two different sets of values of the activation gradient of the neurons as well as (...) six different initial conditions. The given results have been perfectly established using the different fractional-order values on the given derivative operator. The objective of this research is to investigate the dynamics of the proposed HNN model at various values of fractional orders. Nonlocal characteristic of the AB derivative contains the memory in the system which is the main motivation behind the proposal of this research. (shrink)

In a recent article in this journal, Stump argues that pragmatism distances itself from absolutism due to its assent to fallibilism while it rejects relativism at the same time because of its insistence on experience. Therefore, pragmatism can provide a third position between relativism and absolutism. I argue in this note that his argument is profoundly inadequate for both claims. Fallibilism is compatible with both relativism and absolutism, and accordingly cannot be considered as the middle ground. Furthermore, the experience itself (...) and the way it is inferred from is the subject of the relativists’ debates, not a response. (shrink)

Background and aimThe nature of pediatric settings may encounter nurses with more complicated ethical issues. A code of ethics guides nurses to act and decide ethically as a profession. Also, there is always a need to evaluate amount nurses adhere to this code of ethics, using valid and reliable instruments. This study aimed to develop a questionnaire and assess its psychometric properties to measure pediatric nurses' adherence to the code of ethics. MethodsIn this methodological research study, firstly, the questionnaire was (...) developed based on an extensive review of the related literature and the theoretical framework of nursing ethics. A panel of experts (n = 12) reviewed the preliminary questionnaire qualitatively and quantitatively (using CVI and CVR). A conveniently selected sample of 156 nurses working in pediatric wards in three hospitals filled out the questionnaire. The psychometric process included determining sample size and data adequacy using KMO and Bartlette's test of sphericity; exploratory factor analysis (principal component method with Promax rotation); item analysis; and Cronbach's alpha coefficient. Also, the Interclass Correlation Index (ICC) value was determined using a two-week interval test–retest method on 30 eligible nurses.ResultsThe CVI and CVR for the entire questionnaire were 0.85 and 0.78, respectively. The CVI and CVR of all items were reported higher than 0.59 and 0.8, respectively. Cronbach's alpha of the 28-items instrument was 0.92. Extracted six factors explained 65.31% of the total variance, and the values of the item correlations with the total questionnaire showed good internal consistency (0.52 to 0.90). The items of each factor were evaluated to determine the values they represent. Accordingly, the factors were named beneficence, nonmaleficence, human dignity, autonomy, informed consent, and honesty. The ICC value was 0.99.ConclusionsThe developed instrument is acceptable and has good reliability and validity. It can be used to assess the amount of pediatric nurses' adherence to the code of ethics by managers, teachers, and researchers. (shrink)

This article examines how migrant ‘illegality’ is experienced in the Swedish context. How do ‘illegal‘ migrants manage work, housing, healthcare, safety and a family life in the absence of access to formal provisions? What are their survival strategies? I use direct quotations from undocumented migrants themselves to build a multifaceted picture of migrant ‘illegality’. Following Willen's (2007) call for a ‘critical phenomenology of illegality’, I move beyond the socio-political situation of undocumented migrants to their embodied experiences of being ‘illegal’. I (...) conclude that undocumented migrants are not excluded but are excepted; they have not been thrown out, but neither are they considered participants. Undocumented migrants are included in society without being recognised as members. (shrink)

Almost any mainstream reading about the nature of Kant's 'content of cognition' in both non-conceptualist and conceptualist camps agree that 'singular representations' (sensible intuitions) are, at least in some weak sense, objectdependent because they supervene on a manifold of sensations that are given through the disposition of our sensibility and parallel thus the real and physical components of the world (cf. McDowell 1996, Allison 1983, Ginsborg 2008, Allais 2009). The relevant class of sensible intuitions should refer, as they argue, only (...) to empirical and not to pure ones. Kant's transcendental argument creates, however, no implications as to the metaphysics of properties. Neither does he consider the world to be consisted of sensory content simpliciter nor do sensations refer to objects per se. Instead, he provides an all-encompassing pattern for sensible intuitions of any kind through the representation of space as a cognitive map in that an object can be represented if spatial properties are attributed to it. Sensible intuitions of any kind could be referring, that is to say, and can be conceptualized if they are spatial. Consequently and unlike the contemporary philosophy of perception, Kant contrasts sensible intuitions and pure concepts of understanding 'altogether' against one single experience, from which the justification of objects should proceed. In other words, what stands at the core of exposing the content of cognition concerns not the phenomenological status and actuality of sensible intuitions in the sense of 'bits of experiential intake', but the logical structure of possibility of sensible intuitions of any (external or internal) causal background. The aim of this discussion is to clarify that Kant's transcendental idealism mutatis mutandis reviews multiple and diverse kinds of 'data of mind' and cognition in the background, without reducing the content of cognition to metaphysically determined referents as 'matters of fact' and to pure concepts of understanding. Sensible intuitions in the sense of content of cognition vary, most importantly, from unstructured and unjustifiable data of mind including (physical) contents of perception and stuff of mind and also from reflective and intellectual intuitions that are the cognates of the structured complex singular representations. Put it in simple terms, Kant advocates the thesis that 'facts' are objects for concepts if they are already well-founded trough the cognitive map of the representation of space. -/- . (shrink)

BackgroundEthical care provided by nurses to earthquake victims is one of the main subjects in nursing profession.ObjectivesGiven the information gap in this field, the present study is an attempt to explore the nurses’ experience of ethical care provided to victims of an earthquake.Research design and methodA hermeneutic phenomenological study was performed. The participants were 16 nurses involved in providing care to the injured in Kermanshah earthquake, Iran. They were selected using purposeful sampling, and in-depth and semi-structured interviews were carried out. (...) The transcribed interviews were analyzed based on the hermeneutic approach using the analysis method proposed by Diekelmann et al.Ethical considerationsThe study was approved by the Research Council and Ethics Committee of Urmia University of Medical Sciences, Iran.FindingsData analyses revealed four themes and 10 sub-themes that illustrated nurses’ experience of ethical care during earthquake. The themes were (1) Respecting humanistic values (sacrifice, stepping beyond task description, and voluntary work), (2) Commitment to ethics (honesty, confidentiality, and trustworthiness), (3) Respecting dignity of victims (respecting cultural values, maintaining privacy, having humanistic perspective, and effective communication), and (4) Spiritual support (helping patients to do religious rituals Psychological support).ConclusionThe results showed the nurses’ experience with providing care to earthquake victims. The findings underlined ethics and ethical values in providing nursing care during disasters. It is suggested that special courses on the importance of nursing ethics in critical situations be incorporated into nursing curriculums and in-service educations. (shrink)

We completely characterize the logical hierarchy of subsystems of open induction introduced by Boughattas [1].

Doris Lessing, the Persian-born, African-raised and London-residing novelist enjoys a writing career which has spanned more than 50 years. Critics have labeled her as Marxist, feminist, Sufist and even psycho-analyst. It is my contention to prove that latent Sufi characteristics are inherent in her works, and this premise marks a difference between my study and other research on Lessing. To prove that even Lessing’s early works contain Sufi characteristics, this paper looks at her early fictions which lend themselves to Sufistic (...) interpretation. The theoretical framework used in this paper proves the manifestations of Sufism in her early works which involve different Sufistic concepts. The methodology appropriated entails tracing some of these concepts in these novels which are overtly Sufistic. I would also show how Lessing invites a Sufi reading of her novels and whether there are direct signs or changes in her choices of genre, mode, and style that suggest a new vision and a changed worldview and outlook. By revisiting her writing life to show that Sufism has always been present in her works, I depart from other critics and researchers who examine Lessing’s works in more general terms. This departure is significant because the use of a non-western perspective actually enriches our understanding of Lessing who is mainly read from eurocentric points of view. (shrink)

We prove a model theoretic generalization of an extension of the Keisler-Morley theorem for countable recursively saturated models of theories having a K-like model, where K is an inaccessible cardinal.

Suppose L = { <,...} is any countable first order language in which < is interpreted as a linear order. Let T be any complete first order theory in the language L such that T has a κ-like model where κ is an inaccessible cardinal. Such T proves the Inaccessibility Scheme. In this paper we study elementary end extensions of models of the inaccessibility scheme.

Keisler in [7] proved that for a strong limit cardinal κ and a singular cardinal λ, the transfer relation κ → λ holds. We analyze the λ -like models produced in the proof of Keisler's transfer theorem when κ is further assumed to be regular. Our main result shows that with this extra assumption, Keisler's proof can be modified to produce a λ -like model M with built-in Skolem functions that satisfies the following two properties: M is generated by a (...) subset C of order-type λ. M can be written as union of an elementary end extension chain 〈Ni: i < δ 〉 such that for each i < δ, there is an initial segment Ci of C with Ci ⊆ Ni, and Ni ∩ = ∅. (shrink)

Many theorists, in their search for a better explanation of the dynamics of structure and agency, have expressed the need for a theory in which reflexivity and habitus are reconciled. In this article, we argue that a dissociative theory of mind can provide the essential framework in which habitual routines and reflexivity function in parallel. This is explored using the examples of athletic training and hypnosis, where the interplay between conscious and unconscious mechanisms is displayed. In both settings, there is (...) evidence to show that conscious reflexiveness and intersubjective and unconscious automatic processes are necessary to reach the desired outcome. We conclude that a dissociative theory of mind can shed new light on the relationship between habitus and reflexivity. (shrink)

Purpose Over the past decade, many research works in various disciplines have benefited from the endless ocean of people and their potentials as an effective problem-solving strategy and computational model. But nothing interesting is ever completely one-sided. Therefore, when it comes to leveraging people's power, as the dark side of crowdsourcing, there are some possible threats that have not been considered as should be, such as recruiting black hat crowdworkers for organizing targeted adversarial intentions. The purpose of this paper is (...) to draw more attention to this critical issue through investigation of its different aspects. Design/methodology/approach To delve into details of such malicious intentions, the related literature and previous researches have been studied. Then, four major typologies for adversarial crowdsourced attacks as well as some real-world scenarios are discussed and delineated. Finally, possible future threats are introduced. Findings Despite many works on adversarial crowdsourcing, there are only a few specific research studies devoted to considering the issue in the context of cyber security. In this regard, the proposed typologies for such human-mediated attacks can shed light on the way of identifying and confronting such threats. Originality/value To the best of the authors' knowledge, this the first work in which the titular topic is investigated in detail. Due to popularity and efficiency of leveraging crowds' intelligence and efforts in a wide range of application domains, it is most likely that adversarial human-driven intentions gain more attention. In this regard, it is anticipated that the present research study can serve as a roadmap for proposing defensive mechanisms to cope with such diverse threats. (shrink)

In the recent debate on the nature of Kantian ‘content of cognition’, some scholars argue that Kantian judgments of taste bear a nonconceptual mental content because these judgments lack any conceptual determining functions of some kind. In this article, I challenge the latter standpoint for the very simple reason that judgments of taste are no propositions, but rather formative evaluations. This implies as well the fact that we are initially in possession of no aesthetic representation. Hence, neither propositionally nor non-propositionally (...) is an aesthetic representation eligible to be counted as mental content. Instead, as the representation of the beautiful just contents oneself with itself, it refers to its objects relationally, yet not representationally in the full-fledged sense. Regarding the properties of objects, it remains consequently always ineffectively monotonous. On the occasion of agreement of the relevant cognitive faculties, we may, however, count the representation of the beautiful as phenomenal content. -/- . (shrink)

Angels play a central role for Augustine in the Bible and, consequently, in the doctrine of salvation. In his works, he seeks to design a structure to explain the ontological position of angels in order to introduce them as important elements of the theology of salvation. Belief in angels as the helpers of Christ, and Christ himself as the agent of salvation, raises a fundamental question in Augustine's thought: how can the functional role of angels in the process of salvation (...) be considered in the context of the Bible in view of Christ as the Savior of mankind. The authors believe that Augustine interprets the Bible in three stages to solve this dilemma: first, he offers a new interpretation of the theology of the Bible in order to give a different color to the incarnation, and to maintain Christ's superiority over the angels; Second, it describes the role of angels in mediating salvation in view of Christ's saving dignity, and third, it outlines a system of spiritual battle. However, studies show that he did not succeed in this goal. In this study, we aim to consider the basics of the theology of salvation according to the role of angels in Augustine's thought and how it is combined with the place of Christ's salvation, relying on works such as Genesis and commentaries on the Holy Trinity, Psalms and the City of God and his other works. Examine with interpretive-analytical method. (shrink)

In recent years, the amount of data in the world is growing rapidly. Data growth also occurs in the government sector. All ministries and institutions at every level are data producers. These government-owned data have a high potential if they can be used properly. Open government data can stimulate innovation and economic growth and enhance business models. In order to increase the willingness of citizens to use open government data and enjoy the benefits mentioned, the quality of open government data (...) needs to be improved. The quality of open government data encompasses a variety of dimensions and criteria. Also, the importance of each dimension and criterion in increasing the quality of open government data is different. Therefore, we are faced with a complex system that requires proper decision-making and management. In fact, we are dealing with decision-making in the complex management system. Given the importance of this issue, the purpose of this study is to provide a new and comprehensive method to improve the quality of open government data and increase the willingness of citizens to use the data by considering the complex network of citizens and organizations. For this purpose, library studies have been used to extract comprehensive and effective dimensions and criteria. The statistical population includes all articles related to the criteria of improving the quality of open government data and increasing the willingness of citizens to use the data. The probabilistic sampling method of simple random samples has been used, and 10 articles in this field have been reviewed. After extracting the criteria as well as the data of 112 governmental organizations and institutions related to each criterion from the open data portal, the complex network of citizens and governmental organizations and institutions has been analyzed in order to identify high-degree centrality organizations. Then, the data characteristics of the organizations that were most desired by the citizens were extracted using data mining techniques including the regression model. Also, field method and multicriteria decision-making technique including the DEMATEL technique have been used to express the solutions and identify the cause-and-effect relationships between the solutions. The criteria extracted in improving the quality of open government data and increasing the willingness of citizens to use the data are included: “data originality,” “license openness,” “up-to-datedness,” “data access,” “metadata completeness,” “number of data sets,” “format openness,” “nondiscrimination,” “understandable,” “number of categories of data sets,” “free,” “lack of missing data,” “data request ability,” “visualization,” “feedback,” and “data subject matter.” Based on the results obtained from the analysis of the complex network and the regression model, the criterion of “society subject” with a coefficient of 72.564 and a positive sign has the greatest impact on increasing the number of citizens' visits to open government data. After that, the criterion of “format openness” with a coefficient of 52.682 and a positive sign has the second rank in increasing the number of visits. Extracting comprehensive and effective criteria in improving the quality of open government data and increasing citizens' willingness to use data, calculating the weight and importance of each criterion by analyzing the complex network of citizens and organizations, as well as providing solutions, can help managers in decision-making and proper management in the complex system of citizens and government organizations.

The realization of dwindling fossil fuel supplies and their adverse environmental impacts has accelerated research and development activities in the domain of renewable energy sources and technologies. Global energy demand is expected to rise during the next few decades, and the majority of today's energy is based on fossil fuels. Alternative energy sources and technologies can play a vital role in lowering or eliminating our reliance on fossil fuels. However, such a transition will require a large investment and will not (...) be reversible. The benefits of hydrogen and other liquid fuels as transportation fuels are not marginal, but the real urgency in greenhouse gas reductions and fossil fuel replacement should not be translated into an energy infrastructure based on unsustainable sources in the long run. It is wise to examine each option thoroughly and objectively now and discard those with little potential so our focus and effort may be placed elsewhere. (shrink)

Greenhouse gas emissions are adversely affecting the earth’s climate, a global common and a public good. The contribution of individual countries has a limited effect on the biosphere, implying that only globally coordinated efforts may result in significant climate improvements. The Rio Earth Summit (1992) and Kyoto Protocol (1997) are manifestations of international efforts to achieve sustainable development through efficient use of energy and incorporating more renewable sources in global economy. In this article, the author examines the energy-related emissions of (...) greenhouse gases and the utilization of renewable energy sources in Canada with respect to Agenda 21 commitments. An overview of the results of Canada’s policies on climate change since Rio in terms of energy consumption, various sources of energy, and emission rates of greenhouse gases is also presented. It is concluded that the current plans of the Canadian government to deal with greenhouse gas emissions have not been effective. (shrink)

In this study, the speed control of a DC motor with input delay and external disturbance is investigated. A delay-dependent memory state feedback robust predictor-based H ∞ controller that formerly has presented is utilized. Sufficient LMIs conditions provide the stabilizing gain of the predictor-based controller. The first-order model of a DC motor has been studied previously using PID and STA methods. However, in this paper, the delay-dependent robust H ∞ controller is used on both the first and second orders of (...) the DC motor. Finally, the predictor-based H ∞ controller is compared to the PID controller and the common H ∞ controller as well. The simulation results show that the proposed method has been more useful and efficient. (shrink)

In the Corpus Aristotelicum there are two different theories of substance which apply to the sublunary world. The first theory is found in the Categories and selects the individual concrete as a primary substance. The second is found in the Metaphysics and selects the Form and the Essence as a primary substance. Most of the interpretations of modern Aristotelian scholarship claim an inconsistency. They suggest that if at all Aristotle has a theory of substance, then it is either the substance (...) theory of the Categories or the one of the Metaphysics but not both of them. The supposition of all these interpretations is that Aristotle’s theory of substance is unambiguous and that there can be only a single primary substance. These interpretations suppose that the theory of substance is applicable only to a single domain, namely to ontology.In my paper I argue that this supposition is false. I suggest that Aristotle’s theory of substance is applicable not only to ontology but also to the domain of determinology whose meaning is explained in the paper. The theory of substance of the Categories applies to ontology whereas the one of the Metaphysics applies to determinology. The two theories are consistent with each other in a way that there are two commensurate sorts of primary substance: the individual concrete as the ontological primary substance of the Categories and the Form‑Essence as the determinative primary substance of the Metaphysics.Furthermore, I claim that Aristotle’s concept of substance is manifold and flexible. The concept evolves and is expanded in the Metaphysics. It is manifold because his theory of substance has a certain structure which includes the following three criteria for selecting a primary substance: subjecthood viz. being a subject, independence and determined individuality. Aristotle’s concept of substance is flexible because these criteria do not have an absolute signification per se but are general and relative. They get a final signification when they are applied either to the ontology in the Categories or to the determinology in the Metaphysics. Their application to a certain domain establishes a theory of substance according to the domain in question and selects a primary substance according to the same domain. Aristotle’s concept of substance is flexible also because in the Metaphysics he enlarges his first concept of substance expressed by the three criteria by adding a new sort of substancehood expressed by the idion criterion.

Blanchot discusses two versions of imagination. The first version, as the copy of an object, is premeditated or provoked by the conscious process of the mind, whereas in the second version, of the image, a thing becomes a complete empty space outside human consciousness and finds the opportunity to shine itself in itself and for itself. The object never resembles anything but itself, the image of itself. This paper argues that with Blanchot, the human in confrontation with the thing in (...) itself in a passive and neutral relation becomes the image of itself. Keeping a distance from each other not for the sake of knowing and comprehension, both the object and the human are at perpetual distance . While thinking of Blanchot's relationship and distance , it is argued that Ibn 'Arabi's idea of barzakh is the space of imagination, an intermediate reality works through distancing and setting relationship . In this sense, Ibn 'Arabi goes outside ontological horizons believing in essence or existence. (shrink)

Northrop Frye knows the cyclic version of creation myth in his reading of The Four Zoas according to which the human lives in heaven unified with God, unfallen state; he then falls and loses the harmony had with God, fallen state; and he should restore the previous unfallen state in Apocalypse or Last Judgment. Unlike Fry, while thinking of Maurice Blanchot I argue that Blake has created a new myth of creation different from the cyclic one by focusing on what (...) Blake calls Beulah as the stage intermediate between spiritual and physical existence. In the non-original state, Beulah is the state of perpetual creation beyond dialectic and dualism known in Eternity and the life on the earth, a sort of becoming. For Blake, this proves that entities are not created to be manifested in the state of independent selfhood, but they are in relation with the others. This makes both selfhood and indefiniteness simultaneously possible to exist. It is Beulah itself which is all and the only space of existence opening itself from within itself. All entities including God are in interrelationship while being in the process of interruption (acquiring selfhood) within continuation (interrelationship) simultaneously. This demonstrates Blake's new myth of creation avoiding the primal crisis of the cyclic myth of creation. He has also introduced a new idea of relationship. (shrink)

Jacques Derrida’s ethics generates a vision of what the community of nations, states, people is and should be beyond a separation made by what he calls ‘interest’ by which he means that the human interiorizes everything outside himself in order to con­figure a self. For Derrida, forgiveness must not be in the service of any finality such as spiritual, social, national, psychological, and political orientation, since these are reconciliation for the sake of other goals rather than for­giveness. The ‘unconditional forgiveness’ (...) is against the ‘normalization’ by which I argue, in the first section, that Derrida means ‘interest.’ In the second section, through the notion of aporia, without a way out, it is argued that one is situated in the state of ‘difference’ by which Derrida means that an individual is not individual because of difference in identity with another individual, since the identity closes one to the other. Rather, one individual is different from another one by being open to itself and another one. In the forgiveness, this ‘difference’ entails abandoning oneself to the ‘other’ by which one is ‘forgiven for existing.’ The third section discusses Abraham’s sacrifice of his son to illustrate the absolute res­ponsibility for the ‘other’ by which we can rethink morality.

Hydrogen fuel cells are likely to begin replacing conventional internal combustion engines as a power generation method for transportation applications in the near future. A life cycle analysis of a hydrogen fuel cell was performed to examine the major environmental impacts of such an engine in comparison with an internal combustion engine. To quantify the emissions, material consumption and energy consumption were identified by carrying out mass and energy balances, respectively. Wherever possible, a “well-to-wheel” approach was adopted to identify all (...) the processes involved. The size of the hydrogen fuel cell engine selected was 60 kW, which would power a small automobile weighing around 800 kg. This report briefly describes the materials and processes involved in assembling such an engine, with their respective environmental impacts. Different technologies to build a hydrogen economy also are discussed because hydrogen is an integral part of most fuel cell engines. The main conclusion is that if an environmentally sustainable system of hydrogen production is found, the use of hydrogen and, in turn, hydrogen fuel cell cars would be highly beneficial. Thus, the theoretical potential of fuel cells is great for environmental benefits, but practical applications might prove otherwise. (shrink)

In this article, we study set mappings on 4-tuples. We continue a previous work of Komjath and Shelah by getting new finite bounds on the size of free sets in a generic extension. This is obtained by an entirely different forcing construction. Moreover, we prove a ZFC result for set mappings on 4-tuples. Also, as another application of our forcing construction, we give a consistency result for set mappings on triples.

In Bioethics and Secular Humanism: The Search for a Common Morality, Tristram Engelhardt examines various possibilities of finding common ground for moral discourse among people from different traditions and concludes their futility. In this paper I will argue that many of the assumptions on which Engelhardt bases his conclusion about the impossibility of a content-full secular bioethics are problematic. By starting with the notion of moral strangers, there is no possibility, by definition, for a content-full moral discourse among moral strangers. (...) It means that there is circularity in starting the inquiry with a definition of moral strangers, which implies that they do not share enough moral background or commitment to an authority to allow for reaching a moral agreement, and concluding that content-full morality is impossible among moral strangers. I argue that assuming traditions as solid and immutable structures that insulate people across their boundaries is problematic. Another questionable assumption in Engelhardt’s work is the idea that religious and philosophical traditions provide content-full moralities. As the cardinal assumption in Engelhardt’s review of the various alternatives for a content-full moral discourse among moral strangers, I analyze his foundationalist account of moral reasoning and knowledge and indicate the possibility of other ways of moral knowledge, besides the foundationalist one. Then, I examine Engelhardt’s view concerning the futility of attempts at justifying a content-full secular bioethics, and indicate how the assumptions have shaped Engelhardt’s critique of the alternatives for the possibility of content-full secular bioethics.
