Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

It has been hypothesized that psychedelic experiences elicit lasting psychological benefits by altering narrative selfhood, which has yet to be explicitly studied. The present study investigates retrospective reports (n = 418) of changes to narrative self that participants believe resulted from, or were catalysed by, their psychedelic experience(s). Responses to open-ended questions were analysed using inductive and deductive thematic coding and interpreted within agent-centred approaches to development and well-being. Themes include decentred introspection, greater access to self-knowledge, positive shifts in self-evaluation (...) processes, greater psychological and behavioural autonomy, and enhanced connectedness with others and the world. While this explorative qualitative study offers some initial support for the explanation that changes to narrative self are a cornerstone of psychedelics' therapeutic and transformative potential, methodological and recruiting limitations preclude the ability to make objective claims and generalizations. Future scientific research is necessary to further elucidate this hypothesized mechanism. (shrink)

Abstract: The notion of a self-pattern, as developed in the pattern theory of self, which holds that the self is best explained in terms of the kind of reality that pertains to a dynamical pattern, acknowledges the importance of neural dynamics, but also expands the account of self to extra-neural (embodied and enactive) dynamics. The pattern theory of self, however, has been criticized for failing to explicate the dynamical relations among elements of the self-pattern; as such, it seems to be (...) nothing more than a mere list of elements. We’ll argue that the dynamics of a self-pattern are reflected in three significant and interrelated ways that allow for investigation. First, a self-pattern is reflectively reiterated in its narrative component. Second, studies of psychiatric or neurological disorders can help us understand the precise nature of the dynamical relations in a self-pattern, and how they can fail. Third, referencing predictive processing accounts, neuroscience can also help to explicate the dynamical relations that constitute the self-pattern. (shrink)

There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the dissolution of the sense of self and the loss of boundaries between self and world. This article discusses the relevance of this phenomenon, known as “drug-induced ego dissolution (DIED)”, for cognitive neuroscience, psychology and philosophy of mind. Data from self-report questionnaires suggest that three neuropharmacological classes of drugs can induce ego dissolution: classical psychedelics, dissociative anesthetics and agonists of the kappa opioid (...) receptor (KOR). While these substances act on different neurotransmitter receptors, they all produce strong subjective effects that can be compared to the symptoms of acute psychosis, including ego dissolution. It has been suggested that neuroimaging of DIED can indirectly shed light on the neural correlates of the self. While this line of inquiry is promising, its results must be interpreted with caution. First, neural correlates of ego dissolution might reveal the necessary neurophysiological conditions for the maintenance of the sense of self, but it is more doubtful that this method can reveal its minimally sufficient conditions. Second, it is necessary to define the relevant notion of self at play in the phenomenon of DIED. This article suggests that DIED consists in the disruption of subpersonal processes underlying the “minimal” or “embodied” self, i.e., the basic experience of being a self rooted in multimodal integration of self-related stimuli. This hypothesis is consistent with Bayesian models of phenomenal selfhood, according to which the subjective structure of conscious experience ultimately results from the optimization of predictions in perception and action. Finally, it is argued that DIED is also of particular interest for philosophy of mind. On the one hand, it challenges theories according to which consciousness always involves self-awareness. On the other hand, it suggests that ordinary conscious experience might involve a minimal kind of self-awareness rooted in multisensory processing, which is what appears to fade away during DIED.

We are even less aware of our internal organs and the physiological processes that keep us alive. In this fascinating work, Drew Leder examines all the ways in which the body is absent—forgotten, alien, uncontrollable, obscured.

Experiences of Depression is a philosophical exploration of what it is like to be depressed. In this important new book, Matthew Ratcliffe develops a detailed account of depression experiences by drawing on work in phenomenology, philosophy of mind and psychology, and several other disciplines.

Dan Zahavi engages with classical phenomenology, philosophy of mind, and a range of empirical disciplines to explore the nature of selfhood. He argues that the most fundamental level of selfhood is not socially constructed or dependent upon others, but accepts that certain dimensions of the self and types of self-experience are other-mediated.

This paper seeks to illuminate the nature of empathy by reflecting upon the phenomenology of depression. I propose that depression involves alteration of an aspect of experience that is seldom reflected upon or discussed, thus making it hard to understand. This alteration involves impairment or loss of a capacity for interpersonal relatedness that mutual empathy depends upon. The sufferer thus feels cut off from other people, and may remark on their indifference, hostility or inability to understand. Drawing upon the example (...) of depression, I argue that empathy is not principally a matter of ‘simulating’ another person’s experience. It is better conceived of as a perception-like exploration of others’ experiences that develops progressively through certain styles of interpersonal interaction. (shrink)

Phenomenology is the study of structures of consciousness as experienced from the first-person point of view. The central structure of an experience is its intentionality, its being directed toward something, as it is an experience of or about some object. An experience is directed toward an object by virtue of its content or meaning (which represents the object) together with appropriate enabling conditions.

_Heidegger_ is a classic introduction to Heidegger's notoriously difficult work. Truly accessible, it combines clarity of exposition with an authoritative handling of the subject-matter. Richard Polt has written a work that will become the standard text for students looking to understand one of the century's greatest minds.

How should we make choices when we know so little about our futures? L. A. Paul argues that we must view life decisions as choices to make discoveries about the nature of experience. Her account of transformative experience holds that part of the value of living authentically is to experience our lives and preferences in whatever ways they evolve.

This paper integrates personal narratives with the methods of phenomenology in order to draw some general conclusions about ‘what it means’ and ‘what it feels like’ to be depressed. The analysis has three parts. First, it explores the ways in which depression disrupts everyday experiences of spatial orientation and motility. This disruption makes it difficult for the person to move and perform basic functional tasks, resulting in a collapse or contraction of the life-world. Second, it illustrates how depression creates a (...) situational atmosphere of emotional indifference that reduces the person’s ability to qualitatively distinguish what matters in his or her life because nothing stands out as significant or important anymore. In this regard, depression is distinct from other feelings because it is not directed towards particular objects or situations but to the world as a whole. Finally, the paper examines how depression diminishes the possibility for ‘self-creation’ or ‘self-making’. Restricted by the illness, depression becomes something of a destiny, preventing the person from being open and free to access a range of alternative self-interpretations, identities, and possible ways of being-in-the-world.

The normal and the pathological are terms used for structures, activities, individual or collective situations proper to living beings and especially to man. The relation of a fact and a norm is its positive or negative value. Can the assessment of behaviours be reduced to noting a necessity? Is a living being's disease a fact similar to universal attraction? The author maintains that diseases are not merely predetermined effects, but are revealing of a normative regulation proper to living beings and (...) man. (shrink)

Fredrik Svenaeus' book is a delight to read. Not only does he exhibit keen understanding of a wide range of topics and figures in both medicine and philosophy, but he manages to bring them together in an innovative manner that convincingly demonstrates how deeply these two significant fields can be and, in the end, must be mutually enlightening. Medicine, Svenaeus suggests, reveals deep but rarely explicit themes whose proper comprehension invites a careful phenomenological and hermeneutical explication. Certain philosophical approaches, on (...) the other hand - specifically, Heidegger's phenomenology and Gadamer's hermeneutics - are shown to have a hitherto unrealized potential for making sense of those themes long buried within Western medicine.

Havi Carel uses phenomenology to explore how illness modifies the ill person's body, values, and world. Carel argues that illness has received little philosophical attention. Phenomenology of Illness develops a phenomenological framework for illness and a systematic understanding of illness as a philosophical tool.

According to current opinion in western psychopathology, depression is regarded as a disorder of mood and affect on the one hand, and as a distortion of cognition on the other. Disturbances of bodily experience and of social relations are regarded as secondary to the primarily 'inner'and individual disorder. However, quite different concepts can be found in cultures whose members do not experience themselves as much as separate individuals but rather as parts of social communities. Disorders of mood or well-being are (...) then conceived less as intra-psychic, but rather as bodily, interpersonal, or atmospheric processes. On this background, the paper describes depression as a disorder of intercorporeality and interaffectivity. After developing these phenomenological concepts, it analyses depression as a 'detunement' of the resonant body that mediates our participation in a shared affective space. Instead of expressing the self, the body is turned into a barrier to all impulses directed to the environment. This impairs particularly the patient's interaction with others, resulting in a general sense of detachment, separation, or even segregation. Moreover, the restriction of the lived body also corresponds to the triggering situations of depression, namely experiences of a disruption of social bonds. Thus, intercorporeality and interaffectivity are presented as crucial dimensions for an ecological and non-reductionist view of depression. (shrink)

In this paper we discuss the definitional problems of altered states of consciousness and their potential relevance in phenomenological investigation. We suggest that visionary states or visionary phantasy working induced by psychedelics, as extraordinary types of altered states, are appropriate subjects for phenomenological analysis. Naturally, visionary states are not quite ordinary workings of the human mind, however certain cognitive psychological and evolutionary epistemological investigations show that they can give new insights into the nature of consciousness. Furthermore, we suggest that contemporary (...) inquiries concerning altered states in consciousness studies give an opportunity to complete the contemporary phenomenological investigations of phantasy with the notion of visionary phantasy. Here we propose that the similarities and differences between Dieter Lohmar’s weak phantasy and Benny Shanon’s concept of vision are precisely discernible, and, consequently, it may be possible that weak phantasy and visionary phantasy are situated on the two outermost poles of the colorful spectrum of phantasy activity.
