Preface lecture — The Body Has Opinions (Why the strangest mind–body phenomena are not strange at all)

Subtitle: Modal excellence and modal pathology: the same circuitry, facing opposite directions

An opening claim (and a boundary)

The most complex machine in the known universe is not a particle collider or a supercomputer.

It is you: a living system that turns chemistry into perception, perception into meaning, and meaning into action.

This lecture is not a medical diagnosis, and it is not a replacement for care.

It is a map of plausibility.

It explains why medicine has long struggled to describe certain phenomena in plain language, even when the phenomena are real.

Why these phenomena confuse modern medicine

They happen when the body’s signalling networks change state.
