Anil Seth is a world-leading neuroscientist who has made important contributions to our understanding of reality as a controlled hallucination. According to the concept of active inference, our perception of reality is not a direct reflection of the world but, instead, the most accurate guess that our brain can muster, which it continually checks and updates with incoming sensory information. But strange things happen when neuroscientists play around with sensory input in unexpected ways. Anil Seth and his team at Sussex University created the Dream Machine, a stroboscopic device that syncs flickering light to music to induce vivid, often complex, hallucinatory visuals in the viewer. In group sessions, exactly the same white light and music gives rise to a tremendous diversity in perception.

Prof. Larry Nazareth recounts the fundamental difference in perspective that underlies the Cartesian and Bergsonian views of life and world. The former’s dictum states: ‘I compute, algorithmically, therefore I think, symbolically, therefore I am, experientially.’ The latter, however, reverses this dictum: ‘I am, experientially, therefore I think, symbolically, therefore I compute, algorithmically.’ Depending on which of these views we choose to base our understanding of nature and life, we may or may not have a future, Nazareth argues.

How is it possible that the cerebellum, which contains roughly 80% of all the neurons in the human brain, can be severely damaged, or even absent, without abolishing consciousness? In this conversation, Jeremiah Hendren, a member of the Integrated Information Theory (IIT) Lab and long-term collaborator of IIT founder Giulio Tononi, joins Hans Busstra to unpack Integrated Information Theory (IIT), a theory that answers this fascinating neuroscience mystery.

Dr. Currie argues that framing the effectiveness of shamanic medicine in terms of placebo effects alone does not do justice to the sophistication of shamanic practice. The latter, she maintains, is based on a complex, multi-tiered metaphysics whereby cause and effect relations beyond the visible material world are deliberately exploited by the shaman.

In this rigorous and absolutely clear essay, which might as well have been published in an academic journal, Haswell shows that Eliminativism—the notion that the qualities of experience don’t really exist—contradicts not only the most obvious pre-theoretical facts of nature, it also contradicts itself in a manner that cannot be remedied.

In this remarkably observant essay, Brian Fang shows that the mathematics of the ubiquitous Fourier transform—which ties the words of events and frequencies together—provides a formal grammar for understanding how temporality is a facet of eternity, and vice-versa. As such, perhaps what we call “the world” is not fundamentally made of matter unfolding in time, but of patterns that admit atemporal readings. This does not prove idealism, but makes it less strange. If being can be fully captured in structural terms, then perhaps the ultimate constituents of reality are not particles in motion, but intelligible patterns that merely appear temporal when viewed from within.

In this thought experiment mixed with science fiction and serious futurism, eminent neuroscientist Dr. Christof Koch sketches a not-so-distant future in which we will be tempted by the promise of eternal life in an AI cloud. With the fluidity of a novelist, he brings to life this felt temptation, in all its force, just to smash it towards the end. This essay is a critical warning to us all, an attempt to have us confront the problem before we are actually faced with it, so we can protect ourselves with the light of reason.

While Prof. Torday agrees with Federico Faggin that quantum mechanics is salient to consciousness, he maintains that the role of the cell membrane—which separates an organism from its environment—is key to the selective assimilation or mirroring of the quantum properties of the cosmos into the differentiated consciousness of the organism. This essay is short, dense, and may be difficult to unpack. But it handsomely rewards the effort of the patient and determined reader. The many literature citations in the essay also provide rich ground for further exploration.

Moreira argues that Camus, insightful as he was, missed something crucial: in defending his dignity against an absurd world, he remained blind to an emotional truth. What can ultimately sustain us is not the courageous revolt of intellect, but the humility and vulnerability of doubt and uncertainty. For care for the other does not begin in defiance or condescension, but in allowing the other to be insufficient just as we ourselves are.

Hans Busstra and Dr. Lídia del Rio talk to Dr. Matthew Leifer, Assistant Professor of Physics at Chapman University, about the epistemic interpretation of quantum mechanics. Classically, when physicists call themselves ‘realists’ they mean that we should assume that a physical, observer-independent universe is fundamental. But if this counts as realism, anti-realism is perhaps the more respectable position. Leifer points, for instance, to ‘Bell-Wigner mashups’: thought-experiments that entangle different observers to arrive at disturbing consequences; for instance, that there is no ‘absoluteness of facts’ for all observers, in a classical sense.

In this interview, Dr. Philip Cozzolino, an associate professor of psychiatry and neurobehavioral sciences at the University of Virginia, talks with Natalia Vorontsova about his research results and methods for dealing with the fear of death. He also delves into intriguing reincarnation-like cases and past-life memories in children, as well as the metaphysical implications of his research.

Dr. David Schmid, Dr. Lídia Del Rio and Hans Busstra explore a metaphysical shift that’s happening in the foundations of physics: the wave function is no longer regarded as something real, but just as a description of what we know about the world. In philosophical terms: the wave function is not ontic, but epistemic. And in more popular terms: the multiverse is science fiction, resting on a too-literal interpretation of a piece of mathematics called the Schrödinger equation.

In this conversation, neuroscientist Dr. Christof Koch, philosopher Dr. Bernardo Kastrup, and Hans Busstra explore what it means to take mystical experience seriously without abandoning scientific rigor. Both Koch and Kastrup emphasize that some psychedelic experiences exhibit a striking degree of specificity and convergence across individuals, pointing toward possible archetypal universals. While this raises clear ontological questions—suggesting that the contents of mystical experience may, in some sense, be real—the deeper lesson may be epistemic: alongside knowledge gained through scientific experimentation, there may also exist a form of direct acquaintance with truth; a ‘hyper-real’ mode of knowing that can leave the experiencer puzzled for years, or even a lifetime, and can inspire groundbreaking new science.

This eye-opening and important essay argues that Analytic Idealism could help overcome the current conceptual impasse in psychiatry. Dr. Veltri explains how all the major psychiatric disorders can be reinterpreted, in a more therapeutically conducive manner, under the light of an idealist ontology of mind. Indeed, he reframes mental disorders as disturbances in the dissociative boundary between the individual “alter” and universal consciousness, a change of perspective that leads to strong “eureka” moments. The resulting framework makes possible a deconstruction of neuroscientific data and suggests a shift in therapeutic focus toward boundary modulation.

Professor of physics Ivette Fuentes is doing groundbreaking work at the interface of quantum mechanics and gravity. At the heart of Fuentes’ work are Bose–Einstein condensates (BECs)—ultra-cold states of matter in which millions of atoms behave as a single quantum system. These systems are exquisitely sensitive to gravitational effects, making them ideal candidates for probing whether gravity plays an active role in quantum collapse, as Roger Penrose has long suggested. In this conversation with Hans Busstra, Fuentes reflects on her original, cross-disciplinary approach to physics by drawing on her background as a dancer: first, one must fully master the classical forms—the established fields of physics—but true novelty only emerges when one dares to break the rules.
