The Sane Society - Erich Fromm - Google Books
this one happens to have been published the same year of Plath’s death. It must have been in amongst the content of her mind or she read it herself, how I came to discover it. The book does raise some questions that could possibly cause one to feel hopeless but from the small part of it I read I found myself angered not depressed. A clergyman may have found it depressing.
