When your eyelids become a cinema screen: what strobing light reveals about the brain

David Schwartzman is a Research Fellow (Informatics), School of Engineering and Informatics, University of Sussex.
“I study how stroboscopic light stimulation (SLS), flickering light viewed through closed eyes, can alter conscious experience in powerful yet controlled ways. My work examines the visual patterns and altered states SLS can produce, why people respond differently, and how we can study these experiences safely.
A big part of my research is about subjective experience: what people actually feel, see, and report during these states, and how that relates to what is happening in the brain. I’m interested in SLS both as a tool for understanding consciousness and perception, and for its possible practical uses in mental health.
I currently lead an MRC-funded research programme exploring whether SLS could have therapeutic potential for depression. More broadly, my work asks a simple question: if we can safely and reliably shift perception, can that help us better understand the mind — and potentially support wellbeing too?”

Psychedelics and Language Model Temperature

The effect of psychedelics is often described as an increase in fluidity – of being, in some non-specific sense, more free to wander out of usual habit patterns. This essay presents an analogy to a feature of LLMs, namely the temperature parameter, that allows a precise characterisation of this increased fluidity. It begins with a semi-technical description of how this parameter affects the operation of an LLM, and then draws a parallel to how psychedelics affect human experience at multiple levels from perception to thought patterns and life reflections, before concluding by placing this analogy inside a larger project of using the internal mechanism of AI to better understand our own minds.

Three In One Nature of Consciousness & Dream Seequence

Alan MacDonald was a graphic designer and illustrator for 40 years.
“As a metaphysical artist I am concerned with a three-way comparison between: metaphysics (science of subject / why), Science of object (how), and information technology, the most important metaphor we have for the nature of consciousness. Vedic philosophy, describes the three in one nature of consciousness; rishi, devata, chandas (knower, known, process of knowing). My ‘Dream Sequence’ series proposes dreams as daily status reports from the source regarding our level of alignment with the source. I record every dream, interpret upon waking and illustrate it.”

Human vision: what we actually see – and don’t see – tells us a lot about consciousness

Henry Taylor is an associate professor in the Department of Philosophy at the University of Birmingham.
“I’m interested in philosophy of cognitive science, philosophy of mind, metaphysics, and robotics. I have worked on perception, consciousness, attention, peripheral vision, the development of scientific concepts, scientific taxonomy, and robotics. Most of my research involves drawing together work from natural science and philosophy”.

Major theories of consciousness may have been focusing on the wrong part of the brain

Peter Coppola is a Visiting Researcher, Cambridge Neuroscience, University of Cambridge.
“Most of my work focuses on network dynamics, graph theory and consciousness. I am very interested in neurological and neuropsychological cases and what these can tell us regarding consciousness. I intend to investigate how the neuroscience of consciousness can be integrated in clinical psychological practice and ethics.”

How conversation works – and why people with hearing loss rely more on their powers of prediction

Ruth Corps is an Early Career Research Fellow in Psychology, School of Psychology, University of Sheffield.
“I specialise in the cognitive mechanisms supporting conversation and the broader impacts of conversational breakdown and difficulty. My work has predominantly focused on student populations, but I am increasingly interested in populations that struggle with communication (such as those with hearing loss or ADHD) and how these difficulties develop across the lifespan.
I completed both my MA (Hons) in Psychology and my MSc in Psychology of Language at the University of Dundee and my PhD in the Psychology of Language at the University of Edinburgh. My PhD investigated the predictive mechanisms that support rapid turn-taking during conversation, focusing on how predicting what another person is likely to say help us determine what we should say and when we should say it.
After graduating, I stayed at Edinburgh for a further two years as a postdoctoral researcher, investigating how another person’s perspective may help us predict what they are likely to say. I then spent four years at the Max Planck Institute for Psycholinguistics in Nijmegen, investigating the mechanisms supporting conversation in real-world interactions.”

Reflections on the Evolution of Consciousness

Primarily a visual artist, Paul Forte also writes essays and poetry. Forte’s career as an artist began in the San Francisco Bay Area in the early 1970’s. Influenced early on by Conceptual art, Forte has employed a variety of media over the years to realize ideas, including making and self-publishing artist’s books and related objects.
“An experimental approach to art making coupled with an abiding sense of the poetic are the hallmarks of my art. It is an art that has explored this approach and sensibility through a variety of media and artforms over the years: Word works and poetry, artist’s books and book works, performance art, drawings, collage, montage, and assemblage. Central to much of this work is the use of found or appropriated material.”

Voyage to a Beginning: A review of Gary Lachman’s ‘Touched by the Presence’

Luke Gilfedder, a British author and modernist scholar, reviews Gary Lachman’s new memoir, ‘Touched by the Presence: From Blondie’s Bowery and Rock and Roll to Magic and the Occult’. ‘Touched by the Presence’ follows Lachman’s journey from founding member of Blondie to prolific writer on consciousness, counterculture, and the Western esoteric tradition. The book offers a distinctive perspective on the intersection of the arts, existentialism, and the philosophy of consciousness, as experienced by a young person undergoing a major life transition – from member of a world-famous band to full-time author.

Humanism After the Algorithm

This essay examines how artificial intelligence challenges core humanist commitments to reason, moral responsibility, and human judgment. Rather than treating AI as a technical innovation or future speculation, the essay approaches it as a philosophical problem: the emergence of systems whose conclusions increasingly guide human decisions while appearing objective, neutral, and resistant to scrutiny. It argues that the primary risk posed by AI is not replacement of human intelligence, but deference to automated authority. Drawing on themes from epistemology and ethics, the essay explores how algorithmic systems affect moral judgment, empathy, personal agency, and the human search for meaning. While artificial systems may extend human analytical capacity, the essay contends that interpretation, accountability, and ethical responsibility remain irreducibly human. Written for a philosophically engaged, non-specialist audience, the piece defends a humanist framework that emphasizes skepticism, transparency, and responsibility in an increasingly algorithmically mediated world.

The Architecture of Misalignment: Visualizing Domain Coordination in Embodied Experience

Contemporary approaches to emotion and embodiment often diverge along bottom-up (somatic) and top-down (cognitive) lines, giving rise to disagreements about the origins of feeling, the role of meaning, and regulation mechanisms. This paper introduces a visual–operational framework that distinguishes body-led and mind-led domains as coupled operating systems governed by different rules for safety, security, attention, and boundary behavior. Misalignment is modeled as forced single-domain operation, while coherence is defined as restored domain coordination enabling voluntary switching and bidirectional exchange. Through diagrams and visual translation artifacts, the framework functions as an orientation interface that renders existing approaches complementary and interoperable.
