Mind, Matter, and Meaning: A Natural Philosophy of Mind for the Age of Artificial Intelligence, readable in full. Every Part, chapter, and section is listed below; every title links to the full text.
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
Minds reach beyond themselves to the world — and from that one feature, everything follows. The book’s central argument, distilled.
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.

- Chapter Summary
Part Three — Meaning, Self, and Other Minds
