Drawing on philosophy, mysticism, psychiatry, and lived experience, Laing questions the modern tendency to pathologise states of mind that once carried spiritual, ethical, or social significance.

In Wisdom, Madness & Folly, R. D. Laing turns his attention away from diagnosis and toward meaning. Rather than treating madness as a defect to be corrected, Laing asks what it might reveal about the world that produces it. He probes the thin and unstable line between insight and breakdown, sanity and conformity, wisdom and social obedience—suggesting that what we call “mental illness” may, in some cases, be a rational response to an irrational society.

A compact but demanding book, this is Laing at his most reflective and least clinical: unsettling, lucid, and still sharply relevant in an era obsessed with optimisation, wellness, and behavioural normativity.
