New World indigenous peoples are noted for their sophisticated use of psychedelic plants in shamanic and ethnomedical practices. The use of psychedelic plant preparations among New World tribes is far more prevalent than in the Old World. Yet, although these preparations are botanically diverse, almost all are chemically similar in that their active principles are tryptamine derivatives, either...
This perspective examines the role of chemistry and molecular biology for a science of consciousness. Opposed to the consensus view, we argue that the molecular organization of biological systems is key to arrive at a thorough understanding of the dynamics correlated to the phenomenology of consciousness in complex organisms. This is indicated by the fact that the molecular sciences either...
The philosophy of Maurice Merleau-Ponty, a unique blend of existentialism and phenomenology, deserves to be better known in psychiatric-mental health nursing. This philosophy is particularly pertinent to the contemporary recovery movement that seeks to dispel the therapeutic nihilism regarding conditions such as schizophrenia, borderline personality, and substance use disorders. This paper...
This paper revisits the debate about cognitive phenomenology. It elaborates, defends, and improves on our earlier proposal for resolving that debate, according to which the test for irreducible phenomenology is the presence of explanatory gaps. After showing how proposals like ours have been misunderstood or misused by others, we deploy our operationalization to argue that the correct way to...
This article aims to contribute to a better conceptualization of pain and suffering by providing non-essential and non-naturalistic definitions of both phenomena. Contributions of classical evidence-based medicine, the humanistic turn in medicine, as well as the phenomenology and narrative theories of suffering and pain, together with certain conceptions of the person beyond them (the mind-body...
I defend a phenomenological account of the sense of ownership as part of a minimal sense of self from those critics who propose either a deflationary or eliminativist critique. Specifically, I block the deflationary critique by showing that in fact the phenomenological account is itself a deflationary account insofar as it takes the sense of ownership to be implicit or intrinsic to experience...
Time and space are the basic building blocks of nature. As a unique existent in nature, our brain exists in time and takes up space. The brain's activity itself also constitutes and spreads in its own (intrinsic) time and space that is crucial for consciousness. Consciousness is a complex phenomenon including different dimensions: level/state, content/form, phenomenal aspects, and cognitive...
Recognizing that all mental processes have to be unfree and passive, we develop a model of behavior and perceptions. We shall see how misleading our intuition is and shall understand how consciousness arises.
Deconstruction of the theme of the 2017 FQXi essay contest is already an interesting exercise in its own right: Teleology is rarely useful in physics --- the only known mainstream physics example (black hole event horizons) has a very mixed score-card --- so the "goals" and "aims and intentions" alluded to in the theme of the 2017 FQXi essay contest are already somewhat pushing the limits....
What is an urban atmosphere? How can we differentiate an 'atmosphere' from other facets of urban consciousness and experience? This essay explores some of the wider cultural, political, and philosophical connotations of atmospheres as a focal point for critical reflections on space and subjectivity. The idea of an 'affective atmosphere' as a distinctive kind of mood or shared corporeal...
