The project of neurophenomenology, initiated by Francisco Varela, aims at establishing correlations between descriptions of lived experience (as elicited by the explicitation interview technique) and brain states (as measured with increasing precision and detail by the new brain imaging techniques). However, on their own, such correlation aggravates rather than solve Chalmers’ “hard...
Aims This heuristic study reports observations on the phenomenology of ayahuasca experiences of nine foreign tourist participants of an ayahuasca retreat in Peru. Methods Narrative interviews, reflecting individual experiences after ayahuasca “night ceremony,” have been analyzed by qualitative content analysis using a data-driven strategy in order to extract themes and categories inherent in...
Maimonides’s Guide of the Perplexed is incredibly complex and, after millennia, still subject to controversy. In what follows I do not explicitly engage all of the well-known (and well-worn) debates surrounding that text. The aims of this essay are instead to reveal inMaimonides a sort of “phenomenology”—a term that I will clarify shortly but that at the outset should be taken to signal the...
Abstract: A systematic reappraisal of Leibniz’s philosophy of mind. The main argument of this book is easy to state:Leibniz offers a fully natural theory of mind. In today’s philosophical climate in which much effort has been put into discovering a naturalized theory of mind Leibniz’s efforts to reach a similar goal three hundred years earlier will provide a critical stance from which we can...
Despite the physicalistic approach to the mind in the present century, the existence of the mental states different from body states has caused various scales to be put forth regarding mental issues, the most important of which are awareness, being first person, and intentionality. Awareness possesses an extensive domain incorporating senses, perceptions, recalling, visual representation,...
As put forward by neuroscientists, the mechanisms of consciousness can be elucidated by revealing correlations between neural dynamics and specific conscious percepts. Recently, I have elaborated on the mathematical formulation for a system of processes that are mutually connected to be isomorphic to a conscious percept of a point in space. Importantly, in such a system, any process can be...
In this article, we look at the hard problem of consciousness from the perspective of process metaphysics. We thereby identify three problematic premises of the problem that pertain to the constitution of consciousness and its causal relation to the world. We argue for the necessity of re-thinking the corresponding phenomena in terms of internally-structured processes. The hard problem would...
Abstract: One of Anton Wilhelm Amo's core contributions to philosophy is his study of the human mind. Amo argues that the human mind is a purely active, immaterial substance that always acts spontaneously and cannot itself be acted upon. Amo's account of the mind has far‐reaching consequences for how he views the relation between mind and body, and our cognitive relation to the sensible world...
Anomalous or weakened sense of self was central to early theories of schizophrenia. Recent studies have also documented disturbances in body ownership and increased susceptibility for dissociative experiences, such as the out-of-body experience in individuals with schizophrenia, but further research is necessary to clarify components of bodily self-disturbances in the schizophrenia spectrum,...
It is often claimed in parts of the psychiatric literature that neuroscientific research into the biological basis of mental disorder undermines dualism in the philosophy of mind. This paper shows that such a claim does not apply to all forms of dualism. Focusing on Kenneth Kendler's discussion of the mind-body problem in biological psychiatry, I argue that such criticism of dualism often...
The real or perceived proximity to death often results in a non-ordinary state of consciousness characterized by phenomenological features such as the perception of leaving the body boundaries, feelings of peace, bliss and timelessness, life review, the sensation of traveling through a tunnel and an irreversible threshold. Near-death experiences (NDEs) are comparable among individuals of...

According to the Integrated Information Theory of Consciousness, consciousness is a fundamental observer-independent property of physical systems, and the measure Phi of integrated information is identical to the quantity or level of consciousness. For this to be plausible, there should be no alternative formulae for Phi consistent with the axioms of IIT, and there should not be cases of Phi...
In recent decades, attempts to create and argue a new ontology of existence that could provide a robust alternative to the mainstream physicalist metaphysics have been made in science and philosophy. A new book by Bernardo Kastrup (2019, 312 p.), a well-known specialist in the field of philosophy of mind and neuroscience of consciousness, offers the author's conceptually clear and rigorous...
How does the integrated and unified conscious experience arise from the vastly distributed activities of the nervous system? How is the information from the many cones of the retina bound with information coming from the cochlea to create the association of sounds with objects in visual space? In this perspective article, we assert a novel viewpoint on the "binding problem" in which we explain...
Abstract This article is part II of a consideration of phenomenology of religion focusing in this part on the conversation in contemporary French phenomenology. It begins with a brief comment about Heidegger's phenomenology of religious life and then engages most heavily those thinkers who discuss the phenomenon of religion in the Francophone context: Jean Héring, Emmanuel Lévinas, Jean‐Luc...
Recent psychiatric research and treatment initiatives have tended to move away from traditional diagnostic categories and have focused instead on transdiagnostic phenomena, such as hallucinations. However, this emphasis on isolated experiences may artificially limit the definition of such phenomena and ignore the rich, complex, and dynamic changes occurring simultaneously in other domains of...
Empirical descriptions of the phenomenology of meditation states rely on practitioners' ability to provide accurate information on their experience. We present a meditation training protocol that was designed to equip naive participants with a theoretical background and experiential knowledge that would enable them to share their experience. Subsequently, novices carried on with daily practice...

The subjective phenomenology associated with stereopsis, of solid tangible objects separated by a palpable negative space, is conventionally thought to be a by-product of the derivation of depth from binocular disparity. However, the same qualitative impression has been reported in the absence of disparity, e.g., when viewing pictorial images monocularly through an aperture. Here we aimed to...
İlk Çağ’dan beri filozofların temel problemlerinden olan nefsin varlığı, mahiyeti, ölümsüzlüğü ve bedenle ilişkisi konuları, İbn Sînâ metafiziğinin de ontoloji ve epistemoloji arasında köprü görevi gören önemli tartışmalarındandır. İbn Sînâ’nın nefs anlayışı hem Platon hem de Aristoteles felsefeleriyle benzerlikler taşısa da birçok yönüyle ikisini de aşan konumdadır. Ruh-beden problemi...
