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)
