These are the philosophers and scientists I engage most closely in Mind, Matter, and Meaning — the people who shaped the questions I take up and the language I think in. Each name links to a fuller page. Portraits to come.

Featured figures

David Chalmers — He gave the field its defining problem, naming “the hard problem of consciousness” and framing the debate that has dominated it ever since.

Daniel Dennett — One of the most widely read philosophers of mind of the twentieth century, who argued across five decades that consciousness and the self lie within the reach of natural science.

John Searle — One of the most publicly engaged philosophers of his generation, whose Chinese Room permanently altered the debate about artificial intelligence.

Ned Block — One of the most influential philosophers of mind of his generation, whose distinctions — the phenomenal/access divide above all — became standard equipment for the field.

Franz Brentano — Reaching back to Aristotle, he revived intentionality for the modern age and named it the mark of the mental — that every mental state is directed toward an object — setting the agenda for phenomenology and the study of consciousness alike.

Frank Jackson — One of the most admired analytic philosophers of his generation, whose public change of mind about his own famous argument set a rare standard of intellectual honesty.

J. L. Austin — Oxford’s most merciless critical mind, whose Sense and Sensibilia remains the definitive dismantling of the argument from illusion.

Fred Dretske — He built, with a philosopher’s stubbornness, one of the most influential naturalistic theories of mental representation.

Gilbert Harman — His short 1990 paper on the transparency of experience became the hinge of the entire contemporary representationalist debate.

John McDowell — Among the most important anglophone philosophers of the past half-century, whose Mind and World reshaped how philosophers think about experience and the world.

G. E. Moore — He helped end the reign of British idealism and open the analytic era, and his remark on the transparency of experience seeded a century of work on perception.

Michael Tye — The leading contemporary defender of strong representationalism, developed over three decades into the most sophisticated version of the view.

The full roster (A–Z)

Thomas Aquinas — The most systematic mind of medieval Scholasticism, whose account of intentionality anticipated distinctions philosophy of mind would only rediscover six centuries later.

Aristotle — His De Anima remains the foundational text of naturalistic psychology and the starting point for any serious account of intentionality.

Emily Bender and Alexander Koller — Computational linguists who put one of the field’s sharpest arguments about form and meaning — the eavesdropping octopus — into wide circulation.

Tyler Burge — He works with a precision that hides the difficulty of his problems until you try to solve them yourself, and his anti-individualism reshaped how the field thinks about mental content.

Alonzo Church — A founder of theoretical computer science, whose thesis fixed what we mean by “computable” to this day.

Tim Crane — Among the most lucid writers in philosophy of mind, whose work on intentionality and consciousness has shaped the debate more than it is usually credited for.

Francis Crick and Christof Koch — They made consciousness a respectable laboratory problem, launching the modern search for its neural correlates.

Stanislas Dehaene — His Global Neuronal Workspace stands as a model of what the empirical science of consciousness can deliver.

René Descartes — By the standard telling the founder of modern philosophy, and the thinker with whom modern philosophy of mind begins.

Karl Friston — One of the most cited scientists alive, whose free energy principle is the most ambitious formalization of the predictive brain.

Geoffrey Hinton — The most decorated of the researchers who made deep learning work, and a 2024 Nobel laureate in Physics for it.

David Hume — One of the most important figures of the Enlightenment, whose accounts of the self and of causation still set the terms of debate.

Immanuel Kant — He reconciled empiricism and rationalism into one of the most influential systems in the history of thought, and still shapes how we think about perception.

Ray Kurzweil — An engineer of the first rank turned futurist, and the boldest and most consistent popular exponent of the substrate-independence view of mind.

Joseph Levine — He named the explanatory gap, and has spent his career trying to understand why it exists rather than what it might overturn.

David Lewis — One of the most systematic and powerful analytic philosophers of the twentieth century, whose development of functionalism set the terms for much that followed.

John Locke — The most influential British empiricist of his century, whose Essay founded the representative theory of mind.

Ruth Millikan — She founded teleosemantics, one of the most original and technically demanding programs in the philosophy of mind of the past fifty years.

Thomas Nagel — He wrote what may be the most quoted sentence in philosophy of mind, and framed the problem of consciousness for a generation.

Hilary Putnam — He changed his mind more productively than almost any philosopher of his century, building and then rethinking the functionalist program he founded.

Wilfrid Sellars — He wrote one of the most consequential papers in twentieth-century analytic philosophy and diagnosed the Myth of the Given.

Anil Seth — Among the most visible scientific voices on consciousness, and the most eloquent popular champion of the view that perception is a “controlled hallucination.”

Claude Shannon — The founder of information theory, and one of the architects of the digital age.

Giulio Tononi — The author of the most mathematically ambitious theory of consciousness on offer, Integrated Information Theory.

Alan Turing — The founder of theoretical computer science, whose ideas sit at the headwaters of nearly every question about machines and mind.

John von Neumann — A polymath who reshaped logic, physics, and computing, and gave the stored-program computer its canonical design.

Ludwig Wittgenstein — One of the most original philosophers of the twentieth century, and the rare thinker who produced two distinct and opposed philosophical systems.

Arnold Zuboff — He argues that the boundaries between persons are an illusion of perspective, and, separately, that a causally equivalent replacement for part of a brain would leave experience untouched.
