The book: Mind, Matter, and Meaning
A Natural Philosophy of Mind for the Age of Artificial Intelligence
Mind, Matter, and Meaning asks how physical creatures experience and understand a world. Its central argument connects the title’s three terms: physical states acquire meaning through history and use; the felt character of conscious experience consists in the complete way the body and world are presented.
Drawing on a tradition extending from Aristotle and Aquinas through Brentano, the book develops this argument through Dretske and Tye’s representationalism, Putnam’s semantic externalism, and Millikan’s teleosemantics. It defends a physicalism that preserves experience rather than explaining it away, engaging Chalmers on the hard problem, Dennett on the inner theater, and Searle on perception and understanding.
Artificial intelligence puts the account to a further test. What distinguishes linguistic competence from understanding, and what would justify attributing consciousness to a machine? Through language models and robotics, the book examines how a system’s history, organization, and engagement with the world bear on these questions.

Preface
On a school field trip in the early 1970s, I met a computer program called ELIZA. It left me with a question about the nature of understanding that has never quite let go.
Introduction and Chapter-by-Chapter Synopsis
The book’s cumulative argument, followed by a synopsis of every chapter and the Coda.
Part One — Descartes and the Myth of the Inner Theater
How the picture of a mind sealed off from the world got built, and the single thread that begins to unravel it. The same picture, unexamined, is what makes machine consciousness look cheap.

- 11.8 The Flip, Made Stable
- Chapter Summary
Part Three — Meaning, Self, and Other Minds
How meaning reaches the world — and where the case about machine meaning begins: information versus meaning, symbol grounding, why a language model’s eloquence is borrowed; then the assembled self, and how one meaner recognizes another.

Closing
What you get back once the mind is no longer sealed inside — and why a consciousness located within nature is the more astonishing result, not the consolation prize.
Coda · The Marvel of Conscious Existence
The Singularity has arrived as an appearance, not a metamorphosis: what to expect as machines seem conscious, how we could ever know, and how society will cope.
Back Matter
The scholarly apparatus behind the spine — the load-bearing thought experiments and the demoted deep-dives at full strength, for readers who want them.
