The one aspect of reality that I have close acquaintance with—in fact, to adopt the languages of philosophers—the only aspect of the world that I have direct acquaintance with is my own consciousness. I know nothing about the world. The only thing I really know about the world, the only thing I have direct knowledge of, is my sensations.

Ruben Laukkonen and Shamil Chandaria

A Beautiful Loop

Laukkonen and Chandaria propose that consciousness arises from a recursive brain process involving three key elements: a reality model, competitive inferences reducing uncertainty, and a self-aware feedback loop. This framework explains various states of awareness, including meditation, psychedelic experiences, and minimal consciousness. It also offers insights into artificial intelligence by connecting awareness to self-reinforcing predictions. The authors’ theory suggests that consciousness emerges when the brain’s reality model becomes self-referential, creating a “knowing itself” phenomenon. This recursive process underlies different levels of conscious experience and potentially informs AI development.

James Glattfelder

Information — Consciousness — Reality

This open access book chronicles the rise of a new scientific paradigm offering novel insights into the age-old enigmas of existence. Over 300 years ago, the human mind discovered the machine code of reality: mathematics. By utilizing abstract thought systems, humans began to decode the workings of the cosmos. From this understanding, the current scientific paradigm emerged, ultimately discovering the gift of technology. Today, however, our island of knowledge is surrounded by ever longer shores of ignorance. Science appears to have hit a dead end when confronted with the nature of reality and consciousness. In this fascinating and accessible volume, James Glattfelder explores a radical paradigm shift uncovering the ontology of reality. It is found to be information-theoretic and participatory, yielding a computational and programmable universe.

What is it Like to be a Group Agent?

The existence of group agents is relatively widely accepted. Examples are corporations, courts, NGOs, and even entire states. But should we also accept that there is such a thing as group consciousness? I give an overview of some of the key issues in this debate and sketch a tentative argument for the view that group agents lack phenomenal consciousness. In developing my argument, I draw on integrated information theory, a much-discussed theory of consciousness. I conclude by pointing out an implication of my argument for the normative status of group agents.
