"The main purpose of this book is to make a literary, biographical, and scientific argument for a compelling association, not to say actual overlap, between two temperaments- the artistic and the manic-depressive- and their relationship to the rhythms and cycles, or temperament, of the natural world. The emphasis will be on understanding the relationship between moods and imagination, the nature of moods- their variety, their contrary and opposition qualities, their flux, their extremes (causing, in some individuals, occasional episodes of 'madness')- and the importance of moods in igniting thought, changing perceptions, creating chaos, forcing order upon that chaos, and enabling transformation."

Some of the persons mentioned: Byron, Tennyson, Melville, William and Henry James, Schumann, Coleridge, van Gogh, Hemingway, Virginia Wolf. I think she presents a compelling argument that extreme fluctuations in mood, when coupled with an enforced rational thinking process results in more interesting creative output. Granted, their lives may still suck.
