Theodore Dalrymple has been to an inspiring neuropsychiatry convention where he learned about the latest dramatic advances in the fields of neuroimaging, neurochemistry, neurogenetics and so forth.

Scientific self-knowledge, rejoins the ineffable ex-prison doctor, is neither possible, desirable - nor, if achieved, sufferable.
