Our view
“I Will Fear No Evil” is a provocative Heinlein body-swap novel that takes its title from the twenty-third Psalm. Some readers find it entertaining, though very much a product of the hippie era and muddled towards the end; others feel it runs far longer than its idea can carry. It was serialised in the magazine “Galaxy” before appearing as a book in 1970.
