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.

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 conversation with Hans Busstra, the legendary CPU inventor explains his quantum theory of consciousness in more detail and outlines some of his novel ideas, to be presented in his upcoming new book. He discusses, for instance, how we should regard our material universe: “spacetime and matter are the permanent memory of the experience of the self knowing of One.”

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.
