Moses Herzog, a great sufferer, joker, mourner, and charmer. Although his life steadily disintegrates around him—he has failed as a writer and teacher, as a father, and has lost the affection of his wife to his best friends—Herzog sees himself as a survivor, both of his private disasters and those of the age. He writes unsent letters to friends and enemies, colleagues and famous people, revealing his wry perception of the world and the innermost secrets of his heart. [Source]
