Increasing evidence suggests that psychedelic experiences, undergone in controlled conditions, can have various durable psychological benefits. One such benefit is reductions in fear of death, which have been attested in both psychiatric patients and healthy people. This paper addresses the question: how, exactly, do psychedelic experiences reduce fear of death? It argues, against some prominent proposals, that they do so mainly by promoting non-physicalist metaphysical beliefs. This conclusion has implications for two broader debates: one about the mechanisms of psychedelic therapy, (...) and one about the potential non-medical uses of psychedelics for the alleviation of existential angst in psychiatrically healthy people. On the first count, the paper argues that the role of metaphysical belief change in fear of death supports the “Relaxed Beliefs Under Psychedelics” (REBUS) model of psychedelic therapy over alternative accounts. On the second count, the paper argues that the role of metaphysical belief change undermines the proposed use of psychedelics in the “neuroexistentialist” project of naturalizing spirituality. The best available evidence suggests that when psychedelic experiences reduce existential angst and restore a sense of meaning in life, they do so primarily by persuading people of the falsity of a broadly naturalistic worldview, and thus do not help reconcile people to the truth of such a worldview.

In the historical context of a crisis in biological psychiatry, psychedelic drugs paired with psychotherapy are globally re-emerging in research clinics as a potential transdiagnostic therapy for treating mood disorders, addictions, and other forms of psychological distress. The treatments are poised to soon shift from clinical trials to widespread service delivery in places like Australia, North America, and Europe, which has prompted ethical questions by social scientists and bioethicists. Taking a broader view, we argue that the ethics of psychedelic therapy (...) concerns not simply how psychotherapies are different when paired with psychedelic drugs, but how psychedelic therapies shape and are shaped by different values, norms, and metaphysical commitments. Drawing from the published literature and interviews with seven psychedelic therapists working in clinical trials in the United States, Germany, Switzerland, and Australia, this article opens the black box of the treatments to consider the values and informal debates currently animating the therapies. Considering questions of patient autonomy, mechanisms of therapeutic action, and which therapies are best suited to pair with psychedelic substances, we examine the ethics of psychedelic therapy as an emergent form of life. To bring this form of life out in fuller relief, we conclude by comparing and contrasting it with ayahuasca use in Amazonian shamanism. (shrink)

In chapter “Epiphanies and Aspirations: How Psychedelic Experiences Affect Values”, Juuso Kähönen attempts to provide a better understanding of psychedelic drug-induced value changes and reconnections in the user. And he does so by examining the relation between epiphanic transformative experiences, on the one hand, and aspirations—both before and after said experiences—on the other. Specifically, Kähönen argues that psychedelic experiences can temporarily expand, both in width and depth, one’s understanding of values, thereby producing epiphanic transformative experiences and inspiring long-term aspirations toward (...) values. And he contends that, because the user’s prior aspirations shape the context and content of psychedelic experience while epiphanic transformative experiences can inspire subsequent aspirations, such experiences and aspirations can potentially reinforce each other, resulting in what he refers to as a “hermeneutic” process of value learning.

The Comforting Delusion Objection is a central argument in the emerging field of Philosophy of Psychedelics. It posits that while psychedelics may benefit the mental well-being of individuals they also give rise to epistemically unreliable metaphysical beliefs that are incompatible with a naturalist worldview. Assuming naturalism is the correct stance, the result is significant epistemic harm for patients. For this reason, we should hesitate to use psychedelics as a therapeutic aid. In my counterargument, the Faithful Response, I argue that the (...) Comforting Delusion Objection ultimately fails. This failure stems from the plausible assumption that the non-naturalistic metaphysical attitudes resulting from psychedelic experiences are often not beliefs but forms of faith. Faiths, in turn, are nondoxastic and as such, they are not suitable for epistemic evaluation. Therefore, they cannot be justifiably claimed to be epistemically harmful. If no general epistemic harm arises then the Comforting Delusion Objection loses its force. (shrink)

With the rise of the scientific authority of neuroscience and recent neurotechnological advances, the understanding of the human being and its future is beginning to undergo a radical change. As a result, a normative and existential vacuum is opening and hopes as well as fears about the future are flourishing. Some philosophers are anticipating a broad neuroscientific disenchantment, sociocultural disruption and a new existential anxiety related to the clash of the neuroscientific and humanistic image of humans. Others are expecting the (...) technological and scientific developments to lead to human enhancement and existential emancipation. In the first part of this commentary, I outline these two contrasting responses to the rise of neurocentricism and non-anthropocentrism. In the second part, I argue that the divide between the old anthropocentric paradigm and the emerging neuroscientific is misconceived and that literature and fictional narrative are particularly illustrative of the possibility of integrating scientific materialism with humanism. I use the contemporary literary-philosophical work The Creative Act by Rick Rubin to show that humanist ideas can indeed cohere with anti-essentialist and neuroscientific notions of personal identity and self and how existential meaning and comfort can be found in a neuroscientifically and deterministically explained world.
