Altered States of Consciousness

This post is by Marc Wittmann, Research Fellow at the Institute of Frontier Areas of Psychology and Mental Health in Freiburg, Germany. Here, he writes about his new book on altered states of consciousness.



Subjective time emerges through the existence of the self across time as an enduring and embodied entity. This is clearly revealed in everyday states of consciousness such as transiently being in states of boredom or flow. An increased awareness of the self is associated with an increased awareness of time when we are bored. In contrast, we lose track of time and the self when fully immersed in challenging activities accompanied by the feeling of enjoyment – experienced in the state of flow.

The relation between self-awareness and time is even more prominently disclosed in anecdotal reports and empirical studies on altered states of consciousness such as in meditative states, in music-induced trance, and after ingestion of psychedelic substances. In peak states the experience of ‘timelessness’ is reported together with a loss of the sense of self. This is in fact a universal spiritual experience where time is not experienced at all and the self becomes one with the world.

In my book Altered States of Consciousness: Experiences out of Time and Self, just published by MIT Press, I explore these facets of changes in consciousness awareness. After a prologue containing a warm-up with reports of extreme experiences by novelists and Nobel Prize winners, the first chapter covers phenomena under scientific investigation such as the experience of time expansion in moments of terror and accidents (the slow-motion effect), under the influence of drugs, in spiritual moments, and in near death when the heart and brain have apparently stopped functioning. In the second chapter I cover the experience of time and self in meditation.

An abundance of neuroscientific studies exist on meditation effects; and I interview a highly experienced meditator on what he can report to us about his states of “awakening”. In the third chapter I investigate the case of a puzzling psychiatric patient who has lost her emotional feelings, her bodily feelings and the sense of time. Depression and schizophrenia and the latest research on disturbed temporal processing in these patients as well as in certain individuals with epileptic auras are reported. Finally, the latest breathtaking studies on psychedelics such as psilocybin, LSD, and ayahuasca are discussed.


The book presents cases of personal reports and scientific investigations to open the mind up for future conceptualizations that will help to understand phenomenal consciousness, of what makes us humans. An openness to research has developed in the last few years which now allows for systematic studies of psychedelics, near-death experiences, spirituality and meditation, and more. All of these topics were absolutely a no-go only two decades ago. This paradigm shift is touched upon in the epilogue of the book. If we want to understand consciousness we don’t have to be afraid to challenge the foundations of what we know – with scientific methodology.

Delusions in the DSM 5

This post is by Lisa Bortolotti. How has the definition of delusions changed in the DSM 5? Here are some first impressions. In the DSM-IV (Glossary) delusions were defined as follows: Delusion. A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith). When a false belief involves a value judgment, it is regarded as a delusion only when the judgment is so extreme as to defy credibility.

Rationalization: Why your intelligence, vigilance and expertise probably don't protect you

Today's post is by Jonathan Ellis , Associate Professor of Philosophy and Director of the Center for Public Philosophy at the University of California, Santa Cruz, and Eric Schwitzgebel , Professor of Philosophy at the University of California, Riverside. This is the first in a two-part contribution on their paper "Rationalization in Moral and Philosophical thought" in Moral Inferences , eds. J. F. Bonnefon and B. Trémolière (Psychology Press, 2017). We’ve all been there. You’re arguing with someone – about politics, or a policy at work, or about whose turn it is to do the dishes – and they keep finding all kinds of self-serving justifications for their view. When one of their arguments is defeated, rather than rethinking their position they just leap to another argument, then maybe another. They’re rationalizing –coming up with convenient defenses for what they want to believe, rather than responding even-handedly to the points you're making. Yo

A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind

Today's post is by  Karen Yan (National Yang Ming Chiao Tung University) on her recent paper (co-authored with Chuan-Ya Liao), " A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind " ( Synthese 2023). Karen Yan What drives us to write this paper is our curiosity about what it means when philosophers of mind claim their works are informed by empirical evidence and how to assess this quality of empirically-informedness. Building on Knobe’s (2015) quantitative metaphilosophical analyses of empirically-informed philosophy of mind (EIPM), we investigated further how empirically-informed philosophers rely on empirical research and what metaphilosophical lessons to draw from our empirical results.  We utilize scientometric tools and categorization analysis to provide an empirically reliable description of EIPM. Our methodological novelty lies in integrating the co-citation analysis tool with the conceptual resources from the philosoph
