Din-bilim ilişkisi tarihsel süreçte olduğu gibi günümüzde de tartışılmaya devam etmektedir. Hristiyan Avrupa’sında ortaya çıkan tartışmaların İslam dünyasını da etkilediği bir vakıadır. İslam kelamcıları, İslam dini ile bilim arasında bir çatışmanın olmadığı genel kabulüyle hareket ederler. Özellikle bu noktada kelamın vesâil alanı, metafiziğin desteklendiği alan olarak kabul görmektedir. Modern dönemde vesâil alanında önemli bilimsel çalışmaların olduğu görülmektedir bunlardan biri de Nöroteolojidir. Nöroteoloji, davranışı nöral (sinirsel) temelde inceleyip açıklamaya çalışan bilim dalıdır. Bu noktada özellikle dindarlığın nörolojik temelleri ve evrimsel işlevi hakkında (...) önemli bilgiler sunmaktadır. Bu çalışmada kelamın en önemli tartışma konularından biri olan kesb nazariyesi, Nöroteolojik açıdan Benjamin libet deneyiyle değerlendirilmektedir. Deney sonuçları yayınlandığında o güne kadar felsefe ve bilim dünyasında tartışılagelen insanın irade özgürlüğü meselesine yeni bir tartışma zemini hazırlamıştır. Özellikle Eş’ârî’nin kesb anlayışının da ciddi tartışmalara sebebiyet verdiği bilinmektedir. Allah’ın mutlaklığı açısından ele alınan bu düşünce, insan özgürlüğü ve sorumluluğunu ortadan kaldırır düşüncesiyle eleştirilmiştir. Ancak Benjamin libet deneyinin, Eş’ârî’nin kesb anlayışına uygun veriler içermesi dikkat çeken bir husus olarak göze çarpmaktadır. (shrink)

Discussions on the concept of Marifatullah as the foundation of belief hold a significant place in theology. There are different opinions among schools of theology regarding whether those who do not receive divine messages must know God. The majority of scholars belonging to the Mu'tazila and Māturīdī schools, including Imam Māturīdī, state that human beings must know God. Although al-Ashʿarī accepts that the most prominent obligatory duties are the methods of reasoning that lead to marifatullah, he states that responsibility in (...) this matter is formed by transmission. However, we can say that whether the human mind is sufficient to reach the knowledge of God, the method of reasoning has reached a different dimension today from the sciences of psychology, genetics, and neurobiology. This study explored whether individuals can achieve marifatullah from a holistic perspective. Whether human beings can be held responsible for this issue has been evaluated through the sciences of psychology, genetics, and neurobiology, and the opinions of schools of theology on this issue have been criticized. When we think in terms of Marifatullah, we can say that man’s psychological sense of obligation to adapt to society leaves him intellectually under the influence of society. In terms of genetic determinism, human personality, behavior, and intellectual adventure are completely determined by genes. Therefore, it is impossible for men to reach marifatullah in the context of their mental abilities. From an epigenetic perspective, we see that human thought structure, behavior, and personality are formed as a result of interactions with the environment. Serious hesitation arises in this idea in terms of intellect being a source of responsibility. Humans are genetically influenced by the environment and society, and they have a suitable nature for this, revealing that their genetic structure is open to environmental influences. In terms of brain plasticity, factors such as the society, environment, and family in which people live can change their brains and enable them to live accordingly. Although life adventures appear to be within the framework of social harmony, there must also be intellectual and religious harmony within social harmony. This reinforces the idea that individuals tend to align more with the thoughts and beliefs instilled by culture given the adaptable nature of the human brain influenced by cultural factors. When the views of the schools of theology are considered considering these evaluations, it becomes clear that the Mu'tazilites and Māturīdīs' belief that the source of the wujūb of marifatullah is intellect is at a point that needs to be reconsidered in terms of human biology and psychology. Although the Asharites emphasize human beings attaining knowledge of God through intellect, their focus on prophethood indicates that a revelation offer appears more accurate concerning human nature in the context of Marifatullah.

It is necessary to take into account the data of science in the theoretical debates conducted by scientists contributing ontological theories in order to develop new approaches to theological issues in Islamic thought. Even, Kalam scholars with the duty of defending and basing the principles of Islam in the classical sense have established a theological understanding intertwined with science in understanding both existence philosophically and the Script theologically. With its discoveries and theories in the last century, it can be argued (...) that modern science has made a serious progress compared to the past. Maintaining its own methodology and paradigm, every scientific discipline has the opportunity to benefit from the methods and data of other disciplines. Consequently, it is possible to assert that Kalam can enjoy the same opportunity too, as long as staying in its own problem area. According to modern science, the motion system is the unity of structures that enable living things to move. Moreover, Bones and joints, which are the structures of the skeletal system, are passive elements of the movement system. Muscles, on the other hand, are the active elements of the movement system and provide the movement of the body by affecting the bones and joints. Muscle tissue shapes the body by adhering to the bones, besides enabling movement activity to occur. One of the most important systems that provide movement is the nervous system. Because for a person to have movement, the muscles must contract, and the muscles must be stimulated for the contraction of the muscles. The system that enables this contraction to occur is the nervous system. Energy is also required for contraction to occur in the human body. Muscles create energy for movement by first providing their energy from the ATP molecule present in the muscle cells. Considering the movement theories of classical theology scholars, it is seen that they shaped the occurrence of human actions through the concept of potency. While the scholars classify power as spiritual/mental and physical strength in terms of its structure, they have characterized it as accident in terms of its nature. In this context, we can say that the equivalent of the power, which is regarded as necessary for the formation of human acts by the theologians, is the movement system in today's science. The spirit/mental that scholars regard as a structure of power for the occurrence of human action can be regarded as the electrical activity that activates muscles when considered within the framework of the movement system of today's science. It is seen that Kalam scholars emphasize physical competence in their definitions of power as well. At this point, Ash'arians defined the power as the soundness of organs, Mu’tazila expressed it as the presence of organs and their being away from disasters, and the Mâturîdîs stated it as the organs being healthy. With these definitions, Kalam scholars mean that a person should also be physically competent to make a movement. The structures scientifically accepted as biological and physical competence in the movement system are the skeletal system, muscles and nervous system. Therefore, we can say that the strength of the physical fitness/well-being emphasized in the definition of power by theologians corresponds scientifically to the skeletal system, muscles and nervous system. One of the issues that Kalam scholars discuss about power is the issue of the accident of power. The reason why they describe power as an accident is to emphasize its impermanence and to show that it was created by Allah. So, in modern science, electrical activity must occur in the brain in order for human organs to move. The occurrence of this electrical activity is independent of the human being. The fact that electrical activity occurs independently from human beings shows that it conforms to Kalam scholars’ definition of the accident. As a result, we can say that the theory of power created by scholars for human movement has a counterpart in the movement system put forward by today's science. (shrink)

As a result of the developments in science and technology, humanity began to experience a digital transformation after the 19th century. With this digital transformation, it is seen that a serious change has occurred in human beings biologically, socially, and, more specifically, religiously. One could say that different trends have emerged at many points where human relations, the relationship of the human with the environment and with God are also affected. Among the most comprehensive and prominent of these trends is (...) transhumanism because of its aims for humanity and the world. Transhumanism, which views technology as the main point of reference for the future of humanity, is also considered a cultural, social, and ideological human movement with its statements intended for society. It considers immortality as a goal, along with such claims as improving welfare, extending human life, and wiping out diseases by using technology in every aspect of human life. Transhumanists, who claim that they can achieve immortality thanks to technology, argue that this will happen in two ways. The first is biological immortality. It will be achieved by eliminating all kinds of biological factors that lead to humans aging and death. The second is digital or virtual immortality, which is achieved by transferring human consciousness from the biological body to computer interfaces and installing it in any desired entity. This perspective must be critically examined as it can be considered an attempt to challenge death, which is the basic doctrine of classical religions. In the present study, human immortality, considered the most important claim made by transhumanists, is criticized within kalām, Islamic theology. Of course, transhumanists’ account of human immortality is impossible, according to kalām. It can be said that transhumanists view of immortal human can be considered in the category of created beings, which is defined in kalām as "the being created later and needs another being in order to exist and to continue its existence". Given that transhumanists base the idea of the immortal being upon biological healing or digital transmission, it is clear that both types of beings need someone else. Therefore, one could say that it would be more reasonable to define transhumanists’ notion of immortality as the act of prolonging human life. It is because the life of immortal beings, accepted as biological or digital entities, is shaped by many factors. If these factors disappear, so does the being. On the other hand, the attribute of immortality, which belongs to the eternal being only, according to kalām, must come from itself without needing any other being. Therefore, the notion of immortal being suggested by the transhumanists must be reexamined within kalām and be redefined as the extension of life. The redefined immortality as the extension of life hardly poses kalāmī (or theological) problems. In fact, Islam encourages using all types of tools and equipment to enable humans to have a healthy and blissful life. (shrink)

Although Sibawayh dealt with it in a scattered manner under different headings there have been different views on na't (adjective), which is gene-rally included in the tawabi group in Arabic syntax, and there have been debates around these views. Na't, which is categorized as a proper adjective and qualifies the meaning of man'ut (mawsuf), has different characteristics from the sentence elements that indicate the subject. Nahiv scholars have mostly divided na't into two parts: real and causal na't, and they have (...) formulated certain rules for these two parts in accordance with the structure of the Arabic language. Since na't and man'ut are accepted as nouns, the i'rab of na't is subject to men'ut. However, some examples in the Qur'an and some expressions used by the Arabs caused objections to the i'rab of na't being the same as men'ut. It is observed that these objected examples are the cases where men'ut is known and the exceptional cases of madih, zam and jarri jivar. It is also obligatory for the na't to conform to the man'ut in terms of ma'rifiyyah, nekiriyyah, custom and gender. While Sibawayh (d. 180/796) considered it qabh (ugly) for non-propositional words to be na't, scholars such as Ibn Hisham (d. 218/833), Ibn al-Ḥajib (d. 646/1249), and Abd ar-Rahman Jami (d. 898/1492) accepted that na't could be either propositional or non-propositional and cited many examples of na't in the case of non-propositional words. Scholars such as Ibn Jinni (d. 392/1002) and Ibn al-Hajib gave an explanation of the causative na't without naming it, scholars such as Ebu’l-Bekā al-Ukbari (d. 616/1219) analyzed the subject under the title of causative adjective or causative na't, and Halid b. Abdullah al-Azhari discussed it under the title of al-wasf al-majazi. The subject of our study is to examine the handling of na't, which is one of the sentence elements in the Arabic language, in the works written on the field, its parts, the dimension that affects the meaning and the controversial aspects. The aim of the research is to examine the rules that Sibawayh deals with in his al-Kitâb on na'ta and the objections of later Arab linguists to these rules, and to contribute to the field by revealing different views on the subject.

The issue of power has been addressed as part of human actions, which form the basis of the discussions of destiny in Islamic theology. Various schools of kalām have extensively discussed the issue of power throughout history. The locus of power is also one of the critical concerns that have been emphasized within these discussions. The schools of the Mu'tazila, al-Ashʿarī and al-Māturīdī have put forward different perspectives on whether the locus of power exists or not and where it exists (...) if it does so. Mutazilites are known to be in agreement with the view that te human body is the substrate of power. On the other hand, However, they hold different views, not only on the exact locus of power in the body but also on its type. While some argue that the locus of power in the body is the organs, others claim that it is not the organs. The schools of al-Ashʿarī and al-Māturīdī accept that there is no locus for power and emphasize that power is created by Allah the moment it would initiate action. When these views of the kalām schools are considered within the framework of the data from the modern science of anatomy, it is seen that what modern science has to say on this issue concurs well with the Mu'tazilite view that the locus of power is the body and that it creates the action by managing the organs from a single center. This is because, when considered from the lens of anatomy, what is meant by the schools of kalām with “power” is electrical activity (stimulus) that activates the muscles. Therefore, scientifically considered, for any movement to occur, an electrical activity must first begin in the brain and be transmitted to the muscles via motor nerves. If there were no electrical activity in the brain, the muscles and energy that make up the human movement system would not be active, so movement would hardly take locus. Therefore, the claim made some of the Mu'tazili scholars that the power is in the organs is scientifically not valid. As for the debates on whether the power in different organs is the same or different in terms of its type, the views of the scholars who argue that they are the same genus are apparently correct. This is because the electrical activity, which we accept as power, spreads to the organs after it is formed in the brain. This implies that the power which activates the organs is of the same type. However, it can be said that Mu'tazila’s idea of the constant presence of power in its locus conflicts with modern scientific data. The views of al-Ash'arite and al-Maturidite schools that power is free from being in a constant location are compatible with the findings of recent experiments on brain activities. That is, some experimental studies have indicated that the electrical activity that creates an act occurs in the brain before the act itself and outside the will of the human. In brief, the view of Ash'arite and Maturidite scholars that power is not constantly present in the body and that it is created by Allah each time it is needed is compatible with the creation of power, which we define as electrical activity.

‘Abdallāh b. ‘Abd al-Rahmān al-Nāṣir the son of ‘Abd al-Rahmān III is one of the figures who have remained unnoticed both in classical sources and in contemporary studies. Among the main objectives of this research are to compile and collect information about his life, about whom most of the historical sources of al-Andalus give little or no information. According to historical sources, ‘Abdallāh b. ‘Abd al-Rahmān opposed the appointment of his brother al-Hakam II as the heir apparent and was alleged (...) to have masterminded a coup d'état together with some prominent Shāfiʿi scholars of the time, therefore he was arrested at a date close to the Eid al-Adha of 338/950 or 339/951, and then was executed by his very father. However, was this short and seemingly biased narrative really a preparation for a coup d'état or a conspiracy against ‘Abdallāh and his proponents? Why did ‘Abd al-Rahmān not hesitate to make such a sad decision about his own son? So, within the framework of these and similar questions, to reveal the details of the event of ‘Abd al-Rahmān's disappearance by his father and the psychosocial reasons behind it in the light of the current data are among the aims of the research.

S. Jakowski introduced the discussive prepositional calculus D 2as a basis for a logic which could be used as underlying logic of inconsistent but nontrivial theories (see, for example, N. C. A. da Costa and L. Dubikajtis, On Jakowski's discussive logic, in Non-Classical Logic, Model Theory and Computability, A. I. Arruda, N. C. A da Costa and R. Chuaqui edts., North-Holland, Amsterdam, 1977, 37–56). D 2has afterwards been extended to a first-order predicate calculus and to a higher-order logic (cf. the (...) quoted paper). In this paper we present a natural version of D 2, in the sense of Jakowski and Gentzen; as a consequence, we suggest a new formulation of the discussive predicate calculus (with equality). A semantics for the new calculus is also presented. (shrink)

In a previous work [the second and the third author, “On paraconsistent deontic logic”, Philosophia 16, 293-303 (1986)] investigated certain systems of paraconsistent deontic in order to investigate the problem of contradiction in the domain of ethics. This paper continues this line of research, studying some paraconsistent systems containing alethic and deontic modalities. This approach allows us to treat the principles of Kant (OA→ \diamond A) and Hintikka (\square A → OA) from the classical and from the paraconsistent point of (...) view, and to propose systems in which either, both, or neither of these principles is valid.

We propose a formalization of Meinong's theory of objects with the help of Hilbert's $\epsilon$-symbol and a paraconsistent logical system, with an eye towards its application in an axiomatization of the natural sciences.

This paper sets forth and defends a pluriversal approach to religion in the context of an increasingly global bioethics. Section I introduces a pluriversal view as a normative technique for engaging across difference. A normative pluriversal approach sets five constraints: civility, change from within, justice, non-domination, and tolerance. Section II applies a pluriversal approach to religion. It argues that this approach is epistemically just, recognizes diverse standpoints, and represents a productive, preferred, way to tackle global bioethics concerns. Section II also (...) considers an opposing viewpoint, which holds that religious perspectives have no place in bioethics. We show that this viewpoint would have adverse effects on bioethics publishing, conferencing, and training programmes. The paper concludes (in Section III) that bioethicists should engage with people who hold different worldviews, including religious worldviews, and should do so in accordance with pluriversal ethical constraints.

We first show that a theorem by Cartan that generalizes the Frobenius integrability theorem allows us (given certain conditions) to obtain noncurvature solutions for the differential Bianchi conditions and for higher-degree similar relations. We then prove that there is no algorithmic procedure to determine, for a reasonable restricted algebra of functions on spacetime, whether a given connection form satisfies the preceding conditions. A parallel result gives a version of Gödel's first incompleteness theorem within an (axiomatized) theory of gauge fields.

This paper focuses on invasive therapeutic procedures, defined as procedures requiring the introduction of hands, instruments, or devices into the body via incisions or punctures of the skin or mucous membranes performed with the intent of changing the natural history of a human disease or condition for the better. Ethical and methodological concerns have been expressed about studies designed to evaluate the effects of invasive therapeutic procedures. Can such studies meet the same standards demanded of those, for example, evaluating pharmaceutical (...) agents? This paper describes a research project aimed at examining the interplay and sometimes apparent conflict between ethical standards for human research and standards for methodological rigor in trials of invasive procedures. The paper discusses how the authors plan to develop a set of consensus standards that, if met, would result in substantial and much-needed improvements in the methodological and ethical quality of such trials.
