The Druze movement originated at the beginning of the eleventh century and developed out of the Ismā'īlī faction of Shī'ī Islām. Founded by the Ismā'īlī Ḥamza ibn 'Alī, the Tawḥīd is a philosophical and spiritual path that incorporates the fundamentals of Islam, Christianity, and Judaism referred to in the Qur'ān, together with the ancient philosophies of Pythagoras, Plato, Aristotle, Plotinus, and others. It is a synthesis and a unification of the most contradictory thoughts, a synthesis that leads to the real (...) Tawḥīd or "third course".The specificity of the Tawḥīd consists in establishing a bridge between monotheism and non-dualism. To say that God is One does not merely mean... (shrink)

A small but growing number of studies have aimed to understand, assess and reduce existential risks, or risks that threaten the continued existence of mankind. However, most attention has been focused on known and tangible risks. This paper proposes a heuristic for reducing the risk of black swan extinction events. These events are, as the name suggests, stochastic and unforeseen when they happen. Decision theory based on a fixed model of possible outcomes cannot properly deal with this kind of event. (...) Neither can probabilistic risk analysis. This paper will argue that the approach that is referred to as engineering safety could be applied to reducing the risk from black swan extinction events. It will also propose a conceptual sketch of how such a strategy may be implemented: isolated, self-sufficient, and continuously manned underground refuges. Some characteristics of such refuges are also described, in particular the psychosocial aspects. Furthermore, it is argued that this implementation of the engineering safety strategy safety barriers would be effective and plausible and could reduce the risk of an extinction event in a wide range of possible scenarios. Considering the staggering opportunity cost of an existential catastrophe, such strategies ought to be explored more vigorously. (shrink)

Virtual fictionalism is the view that virtual reality is a kind of fiction. We imagine that what we see and hear in virtual reality is real, although it is not. The problem with this view is that there are real moral concerns with our use of virtual reality, from violent video games to cases of virtual groping on social platforms. If what we do in virtual reality is just make-believe, the fictionalist cannot explain the real moral harms of our virtual (...) actions. Call this the moral objection to virtual fictionalism. I address the objection in this paper by arguing for a new fictional account of virtual actions. Virtual fictionalists can take virtual actions to be happening within the fiction and consider users to act as characters or actors within the fictional world depicted in the virtual environment. Instead, I argue that virtual actions create fictional representations from outside the fiction; users act in virtual reality as an author might in their work. The alternative I present better addresses the moral objection to virtual fictionalism—it does not conflate the user with a fictional character. Our virtual actions create fictional representations, and we can morally evaluate them as such. (shrink)

As we learn more about the human brain, novel biotechnological means to modulate human behaviour and emotional dispositions become possible. These technologies could be used to enhance our morality. Moral bioenhancement, an instance of human enhancement, alters a person’s dispositions, emotions or behaviour in order to make that person more moral. I will argue that moral bioenhancement could be carried out in three different ways. The first strategy, well known from science fiction, is behavioural enhancement. The second strategy, favoured by (...) prominent defenders of moral bioenhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I will argue that we ought to implement a combination of the second and third strategies. Furthermore, I will argue that the usual arguments against other instances of human enhancement do not apply to moral bioenhancement, or apply only to the first strategy, behavioural enhancement.

Le problème du schématisme transcendantal est le moment de la Critique de la raison pure où la question de la signification des catégories pousse Kant à remettre en question l’indépendance de l’imagination productive et de l’intuition à l’égard de l’entendement, position que la première rédaction de la Déduction transcendantale partageait encore avec « L’esthétique transcendantale » et la Dissertation de 1770. Ce revirement devient plus explicite et résolu dans la seconde rédaction de la Déduction transcendantale, sans que l’imagination productive, la (...) faculté des intuitions pures, se trouve pour autant réduite à une fonction de l’entendement : si « la synthèse transcendantale de l’imagination » est « un effet de l’entendement sur la sensibilité » selon cette rédaction ( KRV, B 152), c’est parce qu’elle résulte de la détermination a priori, par ce dernier, de certaines activités représentatives pré-conceptuelles dont Kant reconnaît la présence dans la sensibilité animale.

Nous tentons ici de démontrer que le concept du temps absolu, tel qu’il intervient dans le texte des « Analogies de l’expérience », renvoie à une idée régulatrice de la raison qui joue, dans la théorie kantienne de l’expérience, un rôle parallèle à celui qu’attribue Kant à l’idée régulatrice de l’espace absolu dans les Premiers principes métaphysiques de la science de la nature. Dans ce cadre, il s’agit d’établir une distinction nette entre l’idée du temps absolu et l’intuition pure du (...) temps, ainsi que de démontrer que les principes dynamiques de l’entendement pur et, corrélativement, la possibilité de l’expérience, reposent sur cette idée.

Both mainstream cognitive science and analytic philosophy of mind remain wedded to the Cartesian picture of the mind as an isolated, self-sufficient, and constitutively individual phenomenon. However, recently approaches to the mind (e.g. extended mind thesis, enactivism) that depart from the standard view have emerged. Aunifying thread that runs through these approaches can be summed up in the slogan: “to understand mental phenomena one cannot do away with the environment”. Differences between these related views pertain to the strength of the (...) modal operator “cannot”. On the strongest reading the slogan implies that the mind is constituted by the environment. While this interpretation is akin to Marx view on the constitution of consciousness, this link is overlooked in the literature. In this paper, I will argue that Marxists philosophical thinking about the mind, as exemplified by the activity approach, offers a sound philosophical basis for the further development of post-Cartesian views in cognitive science and philosophy of mind. Furthermore, I will argue that the materialistic method proposed by these thinkers is the most promising approach to the problem of naturalizing the mind. (shrink)

The professions have focused considerable attention on developing codes of conduct. Despite their efforts there is considerable controversy regarding the propriety of professional codes of ethics. Many provisions of professional codes seem to exacerbate disputes between the profession and the public rather than providing a framework that satisfies the public''s desire for moral behavior.After examining three professional codes, we divide the provisions of professional codes into those provisions which urge professionals to avoid moral hazard, maintain professional courtesy and serve the (...) public interest. We note that whereas provisions urging the avoidance of moral hazard are uncontroversial, the public is suspicious of provisions protecting professional courtesy. Public interest provisions are controversial when the public and the profession disagree as to what is in the public interest. Based on these observations, we conclude with recommendations regarding the content of professional codes. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Biographical Encyclopedia of British IdealismKarim DharamsiWilliam Sweet, editor. Biographical Encyclopedia of British Idealism. New York-London: Continuum, 2010. Pp. xx + 724. Cloth, $295.00.The term ‘British Idealism’ underdetermines the interests and geographies of philosophers classed under its heading. It may imply a common goal or, indeed, location. This is misleading. The Biographical Encyclopedia of British Idealism goes a long way in demonstrating the challenge of grouping together philosophers with (...) divergent interests and historical pedigrees, sharing some affiliation with Idealist thinking in Britain from the late nineteenth and early twentieth centuries. Many transcend so-called Analytic and Continental categories, and if not transcend, certainly sidestep them. William Sweet’s volume is at once an archaeological guide to British Idealism and a guide to its relevance today. The volume excavates deeply hidden contributions to philosophy and may destabilize our customary assumptions about the geographical limits of Western philosophy; the contributors to the volume ask readers to extend their community of interest to scholars from Southern Africa, India, and East Asia. Calling philosophers working in India and East Asia “British” is also an important reminder; it has its obvious links to British imperium while at the same time speaking to the influence of Idealist thinking outside the frame of colonial England to thinkers working outside the canonical disputes of Western philosophy.This massive volume, uncompromisingly detailed and comprehensive, does have the elements of a survey, but this is not its intent, nor does one get this impression on reading its entries. This Encyclopedia aims to historically and philosophically contextualize Idealist thought. The first six chapters do just this. They are “Idealism in Britain” (William Sweet); “Idealism in Australia and New Zealand” (Mark Weblin); “The Impact of Idealism in North America” (Leslie Armour); “British Idealism in Southern Africa” (William Sweet); “British Idealism in India” (William Sweet); and “British Idealism in East Asia” (William Sweet). [End Page 146] The remainder of the volume includes entries on well-known Idealist philosophers, lesser known thinkers, and important critics of Idealist philosophy, including the familiar and highly influential Russell and Moore. I will say a little bit about the excellent chapter on British Idealism in India.While readers may have familiarity with Idealism in North America and Britain, it may come as a surprise to learn that Indian philosophers, influenced by a great deal of British philosophy, were particularly keen on Idealism in the late nineteenth and early twentieth centuries. Sweet provides readers with a short history of Indian higher education and the place, for instance, of Kant and Hegel in the philosophy curriculum throughout India in the late nineteenth century; it was not long after that British Idealists were being taught to students in Bombay (Mumbai), Madras, and Calcutta (still important centres of higher education in India) along with Allahabad, Mysore, Pondicherry, and Amalner. Idealists in India, much like their counterparts in Britain, labored beyond academic philosophy, extending their discussions to questions of nationalism in India and contributing to ideas in social and political thought.The attraction of British Idealism (indeed, any “Western” Idealist philosophy) to Indian intellectuals may seem mysterious to some readers. Sweet maintains that Indian philosophy was and is by its own historical sense idealist and so the British variant was not so much as “imported” as finding a natural home. Sweet thinks that the revival of interest in the tradition of Advaita Vedanta can be reasonably traced to the influence of British Idealism’s place in Indian philosophy. There is little dispute that Kant, Hegel, and the British thinkers of the late nineteenth and early twentieth centuries influenced how Indian philosophers understood the discipline’s Western identity and aims. Indian philosophers had begun to enter discussions belonging to another history. Hiralal Halder’s Hegelianism and Human Personality, published in 1910, and Ras-Vihari Das’s doctoral dissertation of 1930, The Self and the Ideal, could easily be taken as titles of works in Western European or North American libraries. Philosophy no doubt includes philosophers who come from many histories, and the discipline may be resistant to simple geographical reduction.Sweet cautions readers that Indian philosophers contributed to the development of Indian philosophical thought; they were not merely expositors...

This paper expands Rami Ali’s dissolution of the gamer’s dilemma (Ethics Inf Technol 17:267-274, 2015). Morgan Luck’s gamer’s dilemma (Ethics Inf Technol 11(1):31-36, 2009) rests on our having diverging intuition when considering virtual murder and virtual child molestation in video games. Virtual murder is seemingly permissible, when virtual child molestation is not and there is no obvious morally relevant difference between the two. Ali argues that virtual murder and virtual child molestation are equally permissible/impermissible when considered under different modes of (...) engagement. To this end, Ali distinguishes between story-telling gameplay and simulation games, discussing both in depth. I build on the dissolution by looking into competitive gameplay in order to consider what the morally relevant difference between virtual murder and virtual child molestation might be when competing in a video game. I argue that when competitors consent to participate in a competition, the rules of the competition supersede everyday moral intuitions. As such, virtual competitions ought to represent such consent from virtual characters. Virtual children cannot be represented as giving consent to be molested because (1) children cannot be represented as giving sexual consent, and (2) consent to be possibly molested cannot be given. This creates a morally relevant difference between murder and molestation. By fully addressing competitive gameplay, I answer Luck’s worry that Ali’s dissolution is incomplete (Ethics Inf Technol 20:157-162, 2018). (shrink)

The analysis of the temporal structure of canonical general relativity and the connected interpretational questions with regard to the role of time within the theory both rest upon the need to respect the fundamentally dual role of the Hamiltonian constraints found within the formalism. Any consistent philosophical approach towards the theory must pay dues to the role of these constraints in both generating dynamics, in the context of phase space, and generating unphysical symmetry transformations, in the context of a hypersurface (...) embedded within a solution. A first denial of time in the terms of a position of reductive temporal relationalism can be shown to be troubled by failure on the first count, and a second denial in the terms of Machian temporal relationalism can be found to be hampered by failure on the second. A third denial of time, consistent with both of the Hamiltonian constraints roles, is constituted by the implementation of a scheme for constructing observables in terms of correlations and leads to a radical Parmenidean timelessness. The motivation for and implications of each of these three denials are investigated. (shrink)

This study aims to explore whether a discrepancy exists between the ideal and communicated (disclosed) ethical identity of Islamic banks in Asia and, further, whether there is any association of communicated ethical identity with financial performance. To achieve the objectives, the study analyses data derived from annual reports of Islamic banks in Asia for the period 2006–2010. The results suggest that out of the seven banks studied, three of them are above average and the rest suffer from disparity between the (...) ideal and communicated ethical identities. Further, the study shows that the disclosure of a vision and mission statement; board of directors and top management; zakah, charity, and benevolent loans; and Shari’ah supervisory boards are negatively associated with performance, while the disclosure of products and services and commitment toward employees are positively associated with performance.

Presenta también las explicaciones que reviven este mismo tema en la primera mitad del siglo XX.

Matti Häyry presents a new ethical theory that he calls “conflict-responsive need-based negative utilitarianism.”1 In this commentary, I present my critical observations on his main points against the more general background of utilitarianism and theories of value.

We claim that, as it stands, the Deutsch–Wallace–Everett approach to quantum theory is conceptually incoherent. This charge is based upon the approach’s reliance upon decoherence arguments that conflict with its own fundamental precepts regarding probabilistic reasoning in two respects. This conceptual conflict obtains even if the decoherence arguments deployed are aimed merely towards the establishment of certain ‘emergent’ or ‘robust’ structures within the wave function: To be relevant to physical science notions such as robustness must be empirically grounded, and, on (...) our analysis, this grounding can only plausibly be done in precisely the probabilistic terms that lead to conceptual conflict. Thus, the incoherence problems presented necessitate either the provision of a new, non-probabilistic empirical grounding for the notions of robustness and emergence in the context of decoherence, or the abandonment of the Deutsch–Wallace–Everett programme for quantum theory.

Hamiltonian constraints feature in the canonical formulation of general relativity. Unlike typical constraints they cannot be associated with a reduction procedure leading to a non-trivial reduced phase space and this means the physical interpretation of their quantum analogues is ambiguous. In particular, can we assume that “quantisation commutes with reduction” and treat the promotion of these constraints to operators annihilating the wave function, according to a Dirac type procedure, as leading to a Hilbert space equivalent to that reached by quantisation (...) of the problematic reduced space? If not, how should we interpret Hamiltonian constraints quantum mechanically? And on what basis do we assert that quantisation and reduction commute anyway? These questions will be refined and explored in the context of modern approaches to the quantisation of canonical general relativity. (shrink)

A fundamental tenet of Paul Feyerabend’s pluralistic view of science has it that theory proliferation, that is, the availability of theoretical alternatives, is of crucial importance for the detection of anomalies in established theories. Paul Hoyningen-Huene calls this the Anomaly Importation Thesis, according to which anomalies are imported, as it were, into well-established theories from competing alternatives. This article pursues two major objectives: (a) to work out the systematic details of Feyerabend’s ideas on theory proliferation and anomaly import as they (...) are presented in his early publications and his Against Method and (b) to compare Feyerabend’s ideas on theory proliferation and anomaly import with corresponding features in Popper’s critical rationalist philosophy of science. As it turns out, neither the Principle of Proliferation nor the Anomaly Importation Thesis are necessarily incompatible with critical rationalism. In spite of Feyerabend’s general anti-Popperian attitude, I argue that theoretical pluralism can be seen as an advancement of the critical rationalist philosophy and that critical rationalism provides good arguments for pluralism.

A physically consistent semi-classical treatment of black holes requires universality arguments to deal with the ‘trans-Planckian’ problem where quantum spacetime effects appear to be amplified such that they undermine the entire semi-classical modelling framework. We evaluate three families of such arguments in comparison with Wilsonian renormalization group universality arguments found in the context of condensed matter physics. Our analysis is framed by the crucial distinction between robustness and universality. Particular emphasis is placed on the quality whereby the various arguments are (...) underpinned by ‘integrated’ notions of robustness and universality. Whereas the principal strength of Wilsonian universality arguments can be understood in terms of the presence of such integration, the principal weakness of all three universality arguments for Hawking radiation is its absence.

In recent decades, non-representational approaches to mental phenomena and cognition have been gaining traction in cognitive science and philosophy of mind. In these alternative approach, mental representations either lose their central status or, in its most radical form, are banned completely. While there is growing agreement that non-representational accounts may succeed in explaining some cognitive capacities, there is widespread skepticism about the possibility of giving non-representational accounts of cognitive capacities such as memory, imagination or abstract thought. In this paper, I (...) will critically examine the view that there are fundamental limitations to non-representational explanations of cognition. Rather than challenging these arguments on general grounds, I will examine a set of human cognitive capacities that are generally thought to fall outside the scope of non-representational accounts, i.e. numerical cognition. After criticizing standard representational accounts of numerical cognition for their lack of explanatory power, I will argue that a non-representational approach that is inspired by radical enactivism offers the best hope for developing a genuine naturalistic explanatory account for these cognitive capacities.

Dharamsi considers Collingwood’s defence of the autonomy of the mental and contrasts it with the one articulated by liberal naturalists such as McDowell. Both Collingwood and McDowell, Dharamsi argues, acknowledge the irreducibly normative nature of the study of mind and both reject the widespread naturalist assumption that philosophy is continuous with natural science. The liberal naturalist’s and Collingwood’s strategy are however fundamentally different. McDowell’s strategy is to soften naturalism so as to accommodate within its womb the normative character of the (...) mental, which a harder or more traditional form of naturalism struggles to provide a home for. Collingwood’s strategy agrees with McDowell’s diagnosis of the problem, but not with his proposed solution. For Collingwood, the solution lies not in liberalizing nature, but in rejecting a conception of metaphysics as a science of pure being and understanding it instead as a historical enquiry into the presuppositions of science, including natural science.

This article examines the positions of the modern digital global world in conditions when most processes are implemented through innovative technologies. Thus, modern reality is positioned as a period in which significant connections, including cultural ones, undergo technical and technological changes under the influence of comprehensive processes of digital transformation. This time is considered as a time of new technical and economic development associated with the transition to a new technological order. Digital transformation and the new phenomenon of digital culture (...) that has emerged in connection with it record all changes as prospects for further social development. Priority is given to such areas as digitalization of the cultural environment, the use of a digital management model based on data and a unified administrative policy, improvement of information systems and resources, redesign and electronization of services, expansion of integration capabilities.

BackgroundObtaining informed consent for participation in genomic research in low-income settings presents specific ethical issues requiring attention. These include the challenges that arise when providing information about unfamiliar and technical research methods, the implications of complicated infrastructure and data sharing requirements, and the potential consequences of future research with samples and data. This study investigated researchers’ and participants’ parents’ experiences of a consent process and understandings of a genome-wide association study of malaria involving children aged five and under in Mali. (...) It aimed to inform best practices in recruiting participants into genomic research.MethodsA qualitative rapid ethical assessment was undertaken. Fifty-five semi-structured interviews were conducted with the parents of research participants. An additional nine semi-structured interviews were conducted with senior research scientists, research assistants and with a member of an ethics committee. A focus group with five parents of research participants and direct observations of four consent processes were also conducted. French and translated English transcripts were descriptively and thematically coded using OpenCode software.ResultsParticipants’ parents in the MalariaGEN study had differing understandings of the causes of malaria, the rationale for collecting blood samples, the purposes of the study and the kinds of information the study would generate. Genomic aspects of the research, including the gene/environment interaction underlying susceptibility or resistance to severe malaria, proved particularly challenging to explain and understand.ConclusionsThis study identifies a number of areas to be addressed in the design of consent processes for genomic research, some of which require careful ethical analysis. These include determining how much information should be provided about differing aspects of the research and how best to promote understandings of genomic research. We conclude that it is important to build capacity in the design and conduct of effective and appropriate consent processes for genomic research in low and middle-income settings. Additionally, consideration should be given to the role of review committees and community consultation activities in protecting the interests of participants in genomic research. (shrink)

Econophysics is a new and exciting cross-disciplinary research field that applies models and modelling techniques from statistical physics to economic systems. It is not, however, without its critics: prominent figures in more mainstream economic theory have criticized some elements of the methodology of econophysics. One of the main lines of criticism concerns the nature of the modelling assumptions and idealizations involved, and a particular target are ‘kinetic exchange’ approaches used to model the emergence of inequality within the distribution of individual (...) monetary income. This article will consider such models in detail, and assess the warrant of the criticisms drawing upon the philosophical literature on modelling and idealization.

This article will explore a problem which is related to our moral obligations towards species. Although the re-creation of extinct animals has been discussed to some degree both in lay deliberations as well as by scientists, advocates tend to emphasize the technological and scientific value of such an endeavour, and the “coolness” factor, 32–33, 2013). This article will provide an argument in favour of re-creation based on normative considerations. The environmentalist community generally accepts that it is wrong to exterminate species, (...) for reasons beyond any instrumental value these species may have. It is often also claimed that humanity has a collective responsibility to either preserve or at least to not exterminate species. These two beliefs are here assumed to be correct. The argument presented here departs from and places these two ideas in a deontological framework, from which it is argued that when humanity causes the extinction of a species, this is a moral transgression, entailing a residual obligation. Such an obligation implies a positive duty to mitigate any harm caused by our moral failure. In light of recent scientific progress in the field of genetic engineering, it will be argued that humanity has a prima facie obligation to re-create species whose extinction mankind may have caused, also known as de-extinction.

Embodied and extended cognition is a relatively new paradigm within cognitive science that challenges the basic tenet of classical cognitive science, viz. cognition consists in building and manipulating internal representations. Some of the pioneers of embodied cognitive science have claimed that this new way of conceptualizing cognition puts pressure on epistemological and ontological realism. In this paper I will argue that such anti-realist conclusions do not follow from the basic assumptions of radical embodied cognitive science. Furthermore I will show that (...) one can develop a form of realism that reflects rather than just accommodates the core principles of non-representationalist embodied cognitive science. (shrink)

Starting from a generalized Hamilton-Jacobi formalism, we develop a new framework for constructing observables and their evolution in theories invariant under global time reparametrizations. Our proposal relaxes the usual Dirac prescription for the observables of a totally constrained system and allows one to recover the influential partial and complete observables approach in a particular limit. Difficulties such as the non-unitary evolution of the complete observables in terms of certain partial observables are explained as a breakdown of this limit. Identification of (...) our observables relies upon a physical distinction between gauge symmetries that exist at the level of histories and states, and those that exist at the level of histories and not states. This distinction resolves a tension in the literature concerning the physical interpretation of the partial observables and allows for a richer class of observables in the quantum theory. There is the potential for the application of our proposal to the quantization of gravity when understood in terms of the Shape Dynamics formalism. (shrink)

Symplectic reduction is a formal process through which degeneracy within the mathematical representations of physical systems displaying gauge symmetry can be controlled via the construction of a reduced phase space. Typically such reduced spaces provide us with a formalism for representing both instantaneous states and evolution uniquely and for this reason can be justifiably afforded the status of fun- damental dynamical arena - the otiose structure having been eliminated from the original phase space. Essential to the application of symplectic reduction (...) is the precept that the first class constraints are the relevant gauge generators. This prescription becomes highly problematic for reparameterization invariant theories within which the Hamiltonian itself is a constraint; not least because it would seem to render prima facie distinct stages of a history physically identical and observable functions changeless. Here we will consider this problem of time within non-relativistic me- chanical theory with a view to both more fully understanding the temporal struc- ture of these timeless theories and better appreciating the corresponding issues in relativistic mechanics. For the case of nonrelativistic reparameterization invariant theory application of symplectic reduction will be demonstrated to be both unnec- essary; since the degeneracy involved is benign; and inappropriate; since it leads to a trivial theory. With this anti-reductive position established we will then examine two rival methodologies for consistently representing change and observable func- tions within the original phase space before evaluating the relevant philosophical implications. We will conclude with a preview of the case against symplectic re- duction being applied to canonical general relativity. (shrink)

Brain machine interface (BMI) technology makes direct communication between the brain and a machine possible by means of electrodes.

This is a crucial question, and one that it is a direct descendant of pragmatic inquiry. The essential aim of this kind of analysis, Dewey said, was less to “reach ultimate reality” than to “clarify human ideas in relation to the epoch's social (...) conflicts.”. (shrink)

This is a clear and original investigation of God's nature and existence. First of all, it considers two of God’s traditional properties: being all-knowing and being all-powerful. It argues he cannot possess these properties. But, it argues this is in accord with him being worthy of worship. Secondly, it introduces the notion of evil being “overridden”. It argues he has to bring about other free living things and it is plausible they have to be liable to experience evil due to (...) their conditions. But, it argues the evil in this world is “overridden”. Thirdly, it considers the principal arguments for the claim he does not exist. (They refer to the evil in the world.) It argues they do not establish sufficient grounds for this claim. Finally, it considers some well-known arguments for the claim he exists. It argues they face difficulties. It sets out other arguments. It covers as a whole the principal parts of the Philosophy of Religion. It unifies these parts to a significant degree. It proceeds regularly by way of formal and clear arguments. These arguments are frequently original. It will be of interest to advanced students and specialists in Philosophy, Religious Studies and Theology. Given its explanation of key terms, its jargon-free language, its clarity and brevity...., it will be of interest to others, too. (shrink)

In this paper, we present three methods to give the value of a classical integer in $\lambda\mu$ -calculus. The first method is an external method and gives the value and the false part of a normal classical integer. The second method uses a new reduction rule and gives as result the corresponding Church integer. The third method is the M. Parigot's method which uses the J.L. Krivine's storage operators.
