What is A Beautiful Mind about?

Sylvia Nasar's biography of the mathematician John Nash — Nobel laureate, game theory pioneer, and paranoid schizophrenic — is one of the finest accounts of genius and mental illness in biographical literature. Published in 1998, it traces Nash's improbable trajectory from a brilliant and arrogant graduate student at Princeton in the late 1940s to three decades of psychosis, institutionalization, and social invisibility, and finally to a late-life emergence, recovery, and the Nobel Prize in Economics in 1994.

The early chapters establish Nash's mathematical gifts and his personality's more troubling dimensions. He was visibly contemptuous of colleagues, careless of other people's feelings, and sexually unconventional in ways that generated considerable institutional anxiety in 1950s America. His contributions to mathematics — the Nash equilibrium in game theory, his work on manifolds and partial differential equations — were made in a concentrated burst of about five years and were of sufficient depth that other mathematicians are still unpacking them. Nasar explains the mathematics accessibly without condescending; she is genuinely interested in the ideas, not just the biography.

The breakdown chapters are the most challenging to read. Nash began experiencing symptoms of paranoid schizophrenia in his late twenties — delusions about coded messages in newspapers, a conviction that he was receiving communications from extraterrestrial beings, beliefs about conspiracies that were organized and detailed and entirely disconnected from reality. Nasar traces the decades of hospitalization, electroconvulsive therapy, medication, periods of remission and relapse, and the patient loyalty of Nash's wife Alicia, who divorced him, eventually took him back, and cared for him through the worst years.

The recovery is the biography's most unusual section because it does not conform to standard narrative of treatment and cure. Nash's remission appears to have been largely self-directed — a decision, in his late forties, to begin rejecting the delusional thoughts and to rebuild rational thinking voluntarily. Whether this is accurate self-reporting or a post-hoc rationalization is a question Nasar considers seriously. The Nobel Prize in 1994 was itself a kind of collective judgment that the mathematical work had mattered independently of the life that surrounded it.
