Philosophy of Consciousness

Mon, 01 Jan 0001 00:00:00 +0000

The hard problem of consciousness remains one of the deepest puzzles in philosophy and science. Why should there be something it is like to see red, feel pain, or taste wine? Why doesn’t all this information processing happen in the dark, without any inner light of experience?

My work in this area develops and defends a form of illusionism that reconceives phenomenal properties without eliminativism. Rather than denying that consciousness exists, I argue that our intuitive picture of it — as composed of ineffable, intrinsic qualia — is systematically misleading. The redness of red is not a property of experience itself but a way the brain represents its own states.

AI Minds & Moral Status

Mon, 01 Jan 0001 00:00:00 +0000

When, if ever, would an artificial system deserve moral consideration? This question is no longer science fiction — it is an urgent policy challenge. As AI systems become more sophisticated, the question of their moral status becomes pressing.

I argue that functional integration — not substrate — is the right criterion for moral status. A system deserves moral consideration if it has internal states that influence each other in a globally coherent way, shape behavior across time, and are responsive to the system’s own representations of itself.

Cognitive Neuroscience of Self

Mon, 01 Jan 0001 00:00:00 +0000

Collaborative empirical work on how the brain constructs a sense of self across time. This research program bridges philosophy, cognitive neuroscience, and AI ethics.

Our studies examine dissociative disorders, meditation practices, and predictive processing models to understand how the brain maintains (and sometimes loses) its sense of a unified self. The self, we argue, is not a thing but a process — a predictive model that the brain constructs to reduce uncertainty about its own states.

Ethics of Mind Technology

Mon, 01 Jan 0001 00:00:00 +0000

Brain–computer interfaces, psychedelic therapies, and cognitive enhancement — examining the ethical terrain when we alter the mind deliberately and irreversibly.

As neurotechnology advances, we face unprecedented ethical questions. When we can directly modify brain states, who decides what counts as improvement? What happens to personal identity when memories can be edited? How do we balance therapeutic benefit against the risk of cognitive inequality?

Key Questions

What are the ethical limits of cognitive enhancement?
How should we regulate brain–computer interfaces?
What happens to personal identity when memories are altered?
How do psychedelic therapies challenge traditional models of mental health?

History of Philosophy of Mind

Mon, 01 Jan 0001 00:00:00 +0000

Tracing how Descartes, Hume, James, and Husserl grappled with consciousness, and what their partial successes and failures still teach us about contemporary debates.

The history of philosophy of mind is not merely an academic exercise. Understanding how earlier thinkers framed the mind-body problem helps us see which of our own assumptions are genuinely warranted and which are inherited artifacts of earlier confusions.

Key Questions

What can Descartes’ equivocation teach us about contemporary dualism?
How did Hume’s bundle theory anticipate modern deflationism about the self?
What does William James’s radical empiricism offer to consciousness studies?
How does Husserl’s phenomenology relate to modern neuroscience?

Public Philosophy

Mon, 01 Jan 0001 00:00:00 +0000

Writing for general audiences in Aeon, Nautilus, and The Atlantic; advising government bodies on AI consciousness policy; and hosting the podcast The Observing Mind.

Philosophy too often remains locked in academic journals. My public work aims to bring philosophical questions about consciousness, AI, and the self to broader audiences — not by simplifying them, but by showing that these questions matter for how we live.

Activities

Writing: Regular contributor to Aeon, Nautilus, The Atlantic, and The Guardian
Podcast: Host of The Observing Mind — conversations about consciousness and AI
Policy: Advisory roles with UK AI Safety Institute and EU AI Act working groups
Public Lectures: TED, Royal Institution, Festival of Philosophy

The Self as Story: Narrative Identity and Its Discontents

Tue, 02 Jun 2026 00:00:00 +0000

We tell ourselves we are the authors of our lives. But the neuroscience of memory suggests the narrator is unreliable — and perhaps always was.

Qualia and the Redness of Red

Sun, 15 Mar 2026 00:00:00 +0000

The problem of qualia — why there is something it is like to see red — remains the hardest knot in the philosophy of mind. I examine why functional accounts keep falling short.

Free Will in an Age of Neuroscience

Tue, 20 Jan 2026 00:00:00 +0000

Benjamin Libet’s experiments suggested that unconscious brain activity precedes conscious decisions. Decades later, the implications remain fiercely debated.

The Predictive Brain: Perception as Controlled Hallucination

Sat, 08 Nov 2025 00:00:00 +0000

The brain does not passively receive sensory data. It generates predictions about what is out there and checks them against incoming signals. The implications for our understanding of consciousness are profound.

Why Philosophy Matters for AI Ethics

Sun, 14 Sep 2025 00:00:00 +0000

The ethics of artificial intelligence cannot be reduced to engineering trade-offs. It requires the kind of conceptual clarity that only philosophical inquiry can provide.

Memory, Identity, and the Construction of the Self

Tue, 22 Jul 2025 00:00:00 +0000

John Locke argued that personal identity consists in continuity of memory. Modern neuroscience suggests the relationship between memory and selfhood is more complex — and more interesting — than Locke imagined.

What Would a Conscious AI Actually Feel?

Tue, 10 Jun 2025 00:00:00 +0000

The question sounds like science fiction, but it demands philosophical precision. I argue that asking ‘what it’s like’ to be an AI is already making a loaded assumption about the structure of experience.

The Emotions of Machines: Can AI Feel?

Wed, 30 Apr 2025 00:00:00 +0000

If a machine behaves as though it is in pain, does it matter whether it actually feels pain? The question forces us to disentangle what we mean by emotion, and why the distinction between performance and experience matters.

About

Mon, 01 Jan 0001 00:00:00 +0000

My intellectual home is the hard problem of consciousness — the question of why physical processes give rise to inner experience at all. I approach this through three lenses: metaphysical analysis, cognitive neuroscience, and applied ethics for AI systems.

Before joining MIT, I held positions at the University of Edinburgh and the Max Planck Institute for Empirical Aesthetics. I completed my doctorate at Oxford under the supervision of Prof. John Hare, with a dissertation on higher-order theories of consciousness.
