If one is looking for a solid, non-fiction, overview of the subject written with energy, erudition and even whimsy, Robert Burton's age-old The Anatomy of Melancholy (mentioned glancingly in this book) is still the best and most helpful delving into the subject, both for those simply interested in the phenomenon and, more importantly, from those, like myself, suffering from depression or melancholy and contemplating the possibility of "felo-de-se".
As a reader and a sufferer, I finished this rather bland blook untransformed. And I truly don't understand how this book of limpid prose and scanty overviews ever made it into publication.----Oh yes, forgot, he was a friend of Ms. Plath!
In a more personal vein, Alvarez discusses the fascinating poet Sylvia Plath, with whom he was acquainted, as well as his own depression and attempted suicide. The section on Plath is superb. Alvarez was fond of Plath and he admired her work greatly. He reveals in a clear-eyed manner how the forces tearing her apart were stronger than those holding her together.
"The Savage God" is an absorbing look at a subject often spoken of in whispers. Alvarez points out that people who lose parents at an early age are more likely to take their own lives. He also examines in depth the strong and mysterious link between creative genius and the impulse toward suicide. "The Savage God" is a work that sheds welcome light on the human condition in all of its complexity, yet Alvarez never presumes to provide easy answers to questions that are ultimately unanswerable.
The book's author, A. Alvarez, writes beautifully, giving his readers a loving portrait of Mo Anthoine, a visceral sense of being on a variety of climbs, and much sound and accesible philosophical material to think about.
