Based on a material view and reductionism, science has achieved great success. These cognitive paradigms treat the external as an objective existence and ignore internal consciousness. However, this cognitive paradigm, which we take for granted, has also led to some dilemmas related to consciousness in biology and physics. Together, these phenomena reveal the interaction and inseparable side of...
Abstract According to Viveiros de Castro, comparison as ontology defines the ontological turn in anthropology. It presents a necessity for philosophy to approach the matter with comparative strategy. Morten Pedersen claims that ontological turn should be interpreted as a fulfillment of an anthropological version of Husserl’s method. Thus, phenomenology enters the field of interest along with...
The external clinical manifestations (psychopathology) and internal subjective experience (phenomenology) of catatonia are of clinical importance but have received little attention. This study aimed to use a large dataset to describe the clinical signs of catatonia; to assess whether these signs are associated with underlying diagnosis and prognosis; and to describe the phenomenology of...
Research on mediated social touch (MST) has, either implicitly or explicitly, built on theoretical assumptions regarding social interactions that align with "theory theory" or "simulation theory" of social cognition. However, these approaches struggle to explain MST interactions that occur outside of a laboratory setting. I briefly discuss these approaches and will argue in favor of an...
A recent view on schizophrenia phenomenology underlines the impaired relations between the mind and the body. An aberrant feeling of ipseity may be the real source of suffering of the patients from psychosis and impacts general symptomatology. The disturbed connection between thinking processes and environmental stimuli may lead to language disembodiment. In the study, we aimed to...
Introduction: Hallucinations research is increasingly incorporating philosophy or the work of philosophically trained individuals. We present three different ways in which this is successfully implemented to the enhancement of knowledge and understanding of hallucinations and related phenomena.Method: We review contributions from phenomenology, philosophy of cognitive science, and philosophy of...
According to many first-person accounts, consciousness comprises a subject-object structure involving a mental action or attitude starting from the "subjective pole" upon an object of experience. In recent years, many paradigms have been developed to manipulate and empirically investigate the object of consciousness. However, well-controlled investigation of subjective aspects of consciousness...
In the present work, we aim to make a contribution to the origins of the notion of "minimum self" in Husserl's phenomenology. Starting from the difference between the philosophy of the subject and the philosophy of the self, the aim of this research is to show that the Cartesian association between both philosophies would not exactly correspond to the conception of the self, as we find it in...
This paper presents a version of neurophenomenology based on generative modelling techniques developed in computational neuroscience and biology. Our approach can be described as computational phenomenology because it applies methods originally developed in computational modelling to provide a formal model of the descriptions of lived experience in the phenomenological tradition of philosophy...
Finding a scientific, third-person explanation of subjective experience or phenomenal content is commonly called the "hard problem" of consciousness. There has recently been a surge in neuropsychological research on meditation in general and long-term meditators in particular. These experimental subjects are allegedly capable of generating a stable state of consciousness over a prolonged period...
'Why would we do anything at all if the doing was not doing something to us?' In other words: What is consciousness good for? Here, reversing classical views, according to many of which subjective experience is a mere epiphenomenon that affords no functional advantage, we propose that subject-level experience-'What it feels like'-is endowed with intrinsic value, and it is precisely the value...
Two very fundamental aspects of phenomenal experiences underline the fact that they seem to have "something it's like." One aspect is the fact that experiences have a locus: they Can seem "external" (perceptual), "internal" (interoceptive, bodily or emotional) or "mental." A second fundamental aspect is the imposingness of experiences. They can seem "present" to us in different ways, sometimes...
The concept of schizophrenia (SCZ) was originally associated with a disorder of formal strata of the self. During the last two decades, empirical studies have demonstrated a selective hyper-aggregation of self-disorders in the SCZ spectrum. As with other scientific research areas, the role of self-disturbances in SCZ has been up for debate in various disciplines including cognitive sciences,...
Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue...
In this paper, we present the development of the Altered States Database (ASDB), an open-science project based on a systematic literature review. The ASDB contains psychometric questionnaire data on subjective experiences of altered states of consciousness (ASC) induced by pharmacological and non-pharmacological methods. The systematic review follows the Preferred Reporting Items for Systematic...
Ketamine and its enantiomer esketamine represent promising new treatments for treatment-resistant depression (TRD). Esketamine induces acute, transient psychoactive effects. How patients perceive esketamine treatment, and which conditions facilitate optimal outcomes, remains poorly understood. Understanding patient perspectives on these phenomena is important to identify unmet needs, which can...
