Abstract There is no agreement among psychologists on sources and outcomes of the dreams in human brain during sleep. Secularist scholars of Freudian school of psychoanalysis claim that human dreams reflect their highly subconscious libido. Jungian school of kollective Unbewessustes   disputes such extreme sexualized opinions and highlights the fact that rather large “collective unconscious” than sexuality is shared by representatives of all human cultures. But even without advanced studies, we can risk to believe that our dreams often predict coming events. Artemidoros Daldianus from Ephesus, the second century CE Hellenistic author of Oneirokritikon believed that dreams are human mind’s mirrors of the future. His magnum opus on the art of interpretation of dreams was translated into Arabic by famous Nestorian ophthalmologist Hunayn ibn Ishaq (Iohannitus) of Bayt al-Hikmah during the reign of Abbasid caliphs Maymun and Mutawakkil. The Prophet Muhammad (s.a.w.) often interpreted his own and Sahabah’s dreams with perfect accuracy. In the Qur’an, especially in Surah 12: Yusuf, 36-37, 99-101, the dreams are vehicles of foretelling the future not only of individuals but also of whole nations and states. The paper is written from historical perspective of the Muslim interpretation of dreams which emphasizes the Islamic examination of human dreams in context of the primary sources to the ancient Greek oneiromancy, studied by the Muslim scholars in the early centuries of Islamic Civilization, and their contribution to development of modern oneirology. Keywords: Oneirology, Interpretation of Dreams, Artemidoros’ Oneirocritica, Islamic Ta‘bÊr. Abstrak Tidak ada sebarang persetujuan di kalangan ahli psikologi terhadap sumber dan hasil daripada mimpi di dalam otak manusia semasa tidur. Para sekular Sekolah Psikoanalisis Freud mendakwa bahawa mimpi manusia mencerminkan kesedaran libido. Sekolah Unbewessustes kollective Jungian pertikaikan pendapat seksual melampau tersebut dan menyerlahkan bahawa kebanyakkan kesedaran bukan daripada kesedaran libido dan didapati dalam semua budaya manusia. Tetapi walaupun tanpa kajian yang canggih, kita boleh mengambil risiko untuk mempercayai bahawa mimpi kita sering meramalkan peristiwa yang akan datang. Artemidoros Daldianus dari Efesus, pengarang Hellenistik Oneirokritikon abad kedua CE percaya bahawa mimpi mencerminkan masa depan manusia. Seni interpretasi mimpi beliau telah diterjemahkan ke dalam Bahasa Arab oleh pakar mata Nestorian terkenal Hunayn ibn Ishaq (Iohannitus) dari Bayt al-Hikmah pada zaman pemerintahan khalifah Abbasiyah Maymun dan Mutawakkil. Nabi Muhammad (s.a.w.) sering mentafsirkan mimpi sendiri dan sahabat secara tepat. Dalam Al-Qur'an, terutamanya dalam Surah 12: Yusuf, 36-37, 99-101, mimpi adalah kenderaan untuk meramalkan masa depan bukan sahaja seorang individu tetapi keseluruhan negara dan negeri. Kajian ini ditulis dari perspektif sejarah interpretasi mimpi Islam yang menekankan pemeriksaan mimpi manusia dalam Islam dalam konteks sumber utama oneiromancy purba Yunani yang dikaji oleh para ulama Islam di abad-abad awal tamadun Islam, dan sumbangan mereka kepada pembangunan oneirologi moden. Kata Kunci: Oneirologi, Interpretasi mimpi, Oneirocritica Artemidoros, Ta‘bÊr Islam.

Transhumanism is one of the main “ideologies of the future” that has emerged in recent decades. Its program for the enhancement of the human species during this century pursues the ultimate goal of immortality, through the creation of human brain emulations. Therefore, transhumanism offers its fol- lowers an explicit eschatology, a vision of the ultimate future of our civilization that in some cases coincides with the ultimate future of the universe, as in Frank Tipler’s Omega Point theory. The essay aims to analyze the points of comparison and opposition between transhumanist and Christian eschatologies, in particular considering the “incarnationist” view of Parousia. After an introduction concern- ing the problems posed by new scientific and cosmological theories to traditional Christian eschatology, causing the debate between “incarnationists” and “escha- tologists,” the article analyzes the transhumanist idea of mind-uploading through the possibility of making emulations of the human brain and perfect simulations of the reality we live in. In the last section the problems raised by these theories are analyzed from the point of Christian theology, in particular the proposal of a transhuman species through the emulation of the body and mind of human beings. The possibility of a transhumanist eschatology in line with the incarnationist view of Parousia is refused.

Abstract J.T. Fraser used to emphasize the uniqueness of the human brain in its capacity for apprehending the various dimensions of “nootemporality” (Fraser 1982 and 1987). Indeed, our brain allows us to sense the flow of time, to measure delays, to remember past events or to predict future outcomes. In these achievements, the human brain reveals itself far superior to its animal counterpart. Women and men are the only beings, I believe, who are able to think about what they will do the next day. This is because such a thought implies three intellectual abilities that are proper to mankind: the capacity to take their own thoughts as objects of their thinking, the ability of mental time travels—to the past thanks to their episodic memory or to the future—and the possibility to project very far into the future, as a consequence of their enlarged and complexified forebrain. But there are severe limits to our timing abilities of which we are often unaware. Our sensibility to the passing time, like other of our intellectual abilities, is often competing with other brain functions, because they use at least in part the same neural networks. This is particularly the case regarding attention. The deeper the level of attention required, the looser is our perception of the flow of time. When we pay attention to something, when we fix our attention, then our inner sense of the flux of time freezes. This limitation should not sound too unfamiliar to the reader of J.T. Fraser who wrote in his book Time, Conflict, and Human Values (1999) about “time as a nested hierarchy of unresolvable conflicts.”

Some scientists now argue that humans are really not superior to other species, including our nearest genetic neighbors, chimpanzees and bonobos. Indeed, those animals seem capable of many things previously thought to be uniquely human, including a sense of the future, empathy, depression, and theory of mind. However, it is clear that humans alone produce speech, dominate the globe, and have several brain diseases like schizophrenia. There are three possible sources within the brain for these differences in brain function: in the structure of the brain, in genes coding for proteins in the brain, and in the level of expression of genes in the brain. There is evidence that all three are the case, giving us a place to look for the intersection of the human mind and brain: the expression of genes within neurons of the prefrontal cortex.

In early hominins, there possibly was high selective pressure for the development of reciprocal mother and child vocalizations such as proposed by Falk. In this context, temporoparietal-prefrontal networks that participate in tasks such as working memory and imitation may have been strongly selected for. These networks may have become the precursors of the future language areas of the human brain.

AbstractThe human brain constantly anticipates the future based on memories of the past. Encountering a familiar situation reactivates memory of previous encounters which can trigger a prediction of what comes next to facilitate responsiveness. However, a prediction error can lead to pruning of the offending memory, a process that weakens its representation in the brain and leads to forgetting. Our goal in this study was to evaluate whether memories are spared from pruning in situations that allow for more abstract yet reliable predictions. We hypothesized that when the category, but not the identity, of a new stimulus can be anticipated, this will reduce pruning of existing memories and also reduce encoding of the specifics of new memories. Participants viewed a sequence of objects, some of which reappeared multiple times (“cues”), followed always by novel items. Half of the cues were followed by new items from different (unpredictable) categories, while others were followed by new items from a single (predictable) category. Pattern classification of fMRI data was used to identify category-specific predictions after each cue. Pruning was observed only in unpredictable contexts, while encoding of new items suffered more in predictable contexts. These findings demonstrate that how episodic memories are updated is influenced by the reliability of abstract-level predictions in familiar contexts.
