“An ebullient examination of madness, mortality, suicide... Montero finds that ‘deviance’ is often just a more truthful account of normal human behavior.”—Chris Kraus, author of The Four Spent the Day Together

A dazzling journey into the eccentric, troubled, and luminous minds that shaped literature.

In this bold and deeply researched blend of memoir, essay, literary analysis, and intellectual sleuth story, Montero draws on psychology, neuroscience, and literature, as well as the lives of writers and artists, to explore the connection between creativity and mental vulnerability.

With narrative élan, Montero brings to life figures such as Franz Kafka, Virginia Woolf, Sylvia Plath, Emily Dickinson, Marcel Proust, Joseph Conrad, and Doris Lessing, and paints a fresco of the ways in which the brain works, its quirks and dark corners. Breaking down the forces that influence creativity, Montero proposes new ways of thinking about both the creative act, and what we consider “normal.”

Part intimate memoir, part cultural history, The Danger to Be Sane is a moving and inspirational homage to minds and lives that sit outside of the mean.
