1347The Quantum Darwinist Theory of Consciousness: Resonance, Space-time Emergence, and a Metric for What Makes Something Conscious: A Reply to CriticsJournal of Consciousness Studies 33 (1): 278-341. 2026.In this piece, we present the Quantum Darwinist Theory of Consciousness (QDT), which explains how consciousness arises in biological systems not through isolated, long-lived quantum states, but through recursively stabilized patterns that are repeatedly re-instantiated across neural and microtubular degrees of freedom. This addresses Tegmark’s influential objection that brains are too warm and noisy for quantum effects to matter. We argue that certain geometric structures actually use thermal no…Read more

20Idealism, or Something Near EnoughIn K. Pearce & T. Goldschmidt (eds.), Idealism: New Essays in Metaphysics, Oxford University Press. pp. 275-290. 2017.This chapter develops a critique of physicalism based on the mathematical nature of physics. Drawing from an earlier paper of the author’s, it urges that physicalists need to locate a physicalistically kosher account of the nature of mathematical entities, because fundamental theories in physics are highly mathematical and abstract. At first it may seem that there are many theories in philosophy of mathematics that the physicalist could turn to. But it is argued that the physicalist cannot appea…Read more

1982Quantum mechanics and general relativity provide incompatible descriptions of time. In QM, states evolve unitarily with respect to an external time parameter; in GR, time is a coordinate in a dynamical spacetime geometry. We propose that both quantum and relativistic time emerge from a pre-geometric structure we call Prototime (PT): represented by an orthomodular lattice of consistency relations with zero von Neumann entropy at the fundamental level. PT has no background time, space, or metric—…Read more

811Multi-agent systems often exhibit emergent behavior that appears coordinated, intelligent, and irreducible to the behavior of individual components. Yet quantifying the degree to which such systems form integrated wholes remains a major challenge. While Integrated Information Theory (IIT) was originally developed to explain consciousness, its core concept - measuring how much a system resists decomposition - has broader relevance for understanding informational integration in complex systems. Ho…Read more

12Daniel Dennett on the Nature of ConsciousnessIn Susan Schneider & Max Velmans (eds.), The Blackwell companion to consciousness, Wiley. 2017.One of the most influential philosophical voices in the consciousness studies community is that of Daniel Dennett. Dennett's Consciousness Explained aimed to develop both a theory of consciousness and a powerful critique of the then mainstream view of the nature of consciousness, which Dennett called “The Cartesian Theater View”. This chapter focuses on Dennett's influential critique of the Cartesian Theater View, as well as his positive view on the nature of consciousness, called the “Multiple …Read more

1300The Error Theory of LLM Consciousness: There is No Evidence that Standard LLMs are ConsciousBehavioral and Brain Sciences. forthcoming.I argue that claims that the presence of functional and behavioral analogs of consciousness in LLMs are evidence of AI consciousness should be rejected. Instead, the capability of an LLM trained on human data to emulate human consciousness–related behaviors and functional architecture does not confirm or discredit claims of chatbot consciousness. My “crowdsourced neocortex” account explains why chatbots can assert consciousness and related emotional states, and even exhibit functional configura…Read more

924From LLMs to the Global Brain: the Emergence of Planetary Scale Artificial IntelligenceDisputatio. forthcoming.This article advances the Global Brain Argument, contending that escalating hyperintelli- gent AI systems, from savant-level LLMs to superintelligences, will connect human users, cloud platforms and the internet-of-things to form one or more emergent global brain networks—planetary scale complex adaptive systems that process information, evolve goals and exhibit agential behaviors. I analyse the premises of the argument, contrast the no- tion of AGI with my notions of savant and hyperintelligent…Read more

52Artificial You: AI and the Future of Your MindPrinceton University Press. 2019.Humans may not be Earth’s most intelligent beings for much longer: the world champions of chess, Go, and Jeopardy! are now all AIs. Given the rapid pace of progress in AI, many predict that it could advance to human-level intelligence within the next several decades. From there, it could quickly outpace human intelligence. What do these developments mean for the future of the mind? In Artificial You, Susan Schneider says that it is inevitable that AI will take intelligence in new directions, but…Read more

727Testing for Consciousness in Machines: An Update on the ACT Test for the Case of LLMsCurrent Biology 33 (R1-R10). 2024.This brief piece updates my ACT Test for consciousness in machines for the case of LLMs and is a contribution to a symposium called “Consciousness Beyond the Human” in the journal, *Current Biology*. This piece urges that the ACT can be updated for the case of LLMs, providing a ‘marker’ to those systems that passed the updated ACT. (However, readers should see the newer update as well, which appeared in *Scientific American* in May, 2025. This suggests there is only a “weak marker” because a “cr…Read more

How to Catch an AI Zombie: Testing for Consciousness in MachinesIn S. Matthew Liao (ed.), Ethics of Artificial Intelligence, Oxford University Press. 2020.In this chapter, I sketch a provisional framework for testing artificial consciousness. According to this framework, detecting machine consciousness is like diagnosing a medical illness. There may be a variety of useful tests and markers for detecting synthetic consciousness, some of which are more authoritative than others, and the appropriate use of any one test depends upon contextual factors. Further, because the tests are at an early stage of development, where two or more tests can be used…Read more

170Mind Design, AI Epistemology, and OutsourcingSocial Epistemology. 2025.From brain machine interfaces to neural implants, present and future technological developments are not merely tools, but will change human beings themselves. Of particular interest is human integration with AI. In this paper, we focus on enhancements that enable us to outsource epistemic work to AI. How does outsourcing epistemic work to enhancements affect the authorship of and responsibility for the final product of that work? We argue that in the context of performing and reporting research,…Read more

44IntroductionIn Science Fiction and Philosophy: From Time Travel to Superintelligence, Wiley-blackwell. 2016.Thought experiments are windows into the fundamental nature of things. They can demonstrate a point, entertain, illustrate a puzzle, lay bare a contradiction in thought, and move us to provide further clarification. Some of the best science fiction tales are in fact long versions of philosophical thought experiments. From Arthur C. Clark's film 2001: A Space Odyssey, which explored the twin ideas of intelligent design and artificial intelligence gone awry, to the Matrix films, which were partly …Read more

64MindscanIn Science Fiction and Philosophy: From Time Travel to Superintelligence, Wiley-blackwell. 2016.Transhumanists share the belief that an outcome in which humans have radically advanced intelligence, near immortality, deep friendships with AI creatures, and elective body characteristics is a very desirable end, both for one's own personal development and for the development of our species as a whole. This chapter employs science fiction thought experiments to discuss the most important philosophical element of the transhumanist picture ‐ its unique perspective on the nature and development o…Read more

115Alien MindsIn Science Fiction and Philosophy: From Time Travel to Superintelligence, Wiley-blackwell. 2016.This chapter first explains why it is likely that the alien civilizations we encounter will be forms of superintelligent artificial intelligence (SAI). Next, it turns to the question of whether superintelligent aliens can be conscious – whether it feels a certain way to be an alien, despite their non‐biological nature. The chapter draws from the literature in philosophy of AI, and urges that although we cannot be certain that superintelligent aliens can be conscious, it is likely that they would…Read more

2337SuperpsychismJournal of Consciousness Studies. 2026.Two of life’s greatest mysteries are the phenomena of consciousness and the nature of spacetime. Herein, we use quantum entanglement as an inroad to both, developing a new “superpsychist” panpsychist theory. First, we frame and defend a position in which spacetime emerges from an aspatial, quasi-temporal, reality called “prototime.” We call this view of quantum phenomena the “Prototime Interpretation.” Then, based on our position on entanglement, we develop a new version of panpsychism, which w…Read more

1371The Global Brain Argument contends that many of us are, or will be, part of a global brain network that includes both biological and artificial intelligences (AIs), such as generative AIs with increasing levels of sophistication. Today’s internet ecosystem is but a hodgepodge of fairly unintegrated programs, but it is evolving by the minute. Over time, technological improvements will facilitate smarter AIs and faster, higher-bandwidth information transfer and greater integration between devices…Read more

114If You Upload, Will You Survive?In Russell Blackford & Damien Broderick (eds.), Intelligence Unbound, Wiley-blackwell. 2014.This chapter discusses the two general kinds of uploading scenarios and given our response to Chalmers' objections, let us summarize where things stand. First, there is considerable reason to be pessimistic about instantaneous destructive uploading's ability to preserve identity or to produce continuations of the original person. Second, there is also good reason to be pessimistic about gradual destructive uploading's ability to preserve identity or produce continuations, since exactly the same …Read more

Building on our earlier work, it argues that the aspects of cognitive functioning that are central to the preservation of personal identity are those surrounding consciousness. Neural enhancements that do not preserve consciousness do not preserve personal identity. Examining in particular the influential arguments of Clark, Clowes, Gärtner, and others regarding the extended mind, we argue for a pe…Read more

935Illusory world skepticismPhilosophy and Phenomenological Research 109 (3): 1049-1057. 2024.l argue that, contra Chalmers,a skeptical scenario involving deception is a genuine possibility,even if he is correct that simulations are real. I call this new skeptical position “Illusory World Skepticism.” Illusory World Skepticism draws from the simulation argument,together with work in physics,astrobiology, and AI,to argue that we may indeed be in an illusory world—a universe scale simulation orchestrated by a deceptive AI—the technophilosopher’s ultimate evil demon. In Section One I urge t…Read more

2150Chatbot EpistemologySocial Epistemology 39 (5): 570-589. 2025.This piece considers the epistemological challenges that arise with the increasingly widespread use of AI chatbots. I articulate a problem that they present—the ‘boiling frog problem’. According to the metaphor, if you boil a frog by putting it in scalding water, it will try to save itself, but if you put the frog in a pot of tepid water, it will remain unaware of the rising water temperature and therefore, make no attempt to escape to save itself. In both cases, the outcome is the same—the frog…Read more

1093The Prototime Interpretation of Quantum MechanicsIn Dean Rickles & Hatam Elshatlawy (eds.), Rickles, D., X. D. Arsiwalla, and H. Elshatlawy (eds.). 2025. Quantum Gravity and Computation: Information, Pregeometry, and Digital Physics. New York: Routledge.. forthcoming.We propose the Prototime Interpretation of quantum mechanics, which claims that quantum entanglement occurs in a "prototemporal" realm that underlies spacetime. Our paper is tentative and exploratory. The argument form is inference to the best explanation. In Section One, we claim that the Prototime Interpretation (PI) is worthy of further consideration as a superior explanation for perplexing quantum phenomena such as delayed choice, superposition, the wave-particle duality and nonlocality. In…Read more
