Carl Jung was one of the 20th century’s most significant psychological theorists. He developed concepts we use every day - introverts and extroverts chief among them. Mark Vernon’s eight-part book explores some of Jung’s key ideas and also looks at his relationship with the other giant of the mind - Sigmund Freud. The How to Believe series of books explores the teachings, philosophies, and beliefs of major thinkers and religious texts. In a short, easy-to-access format, leading writers present new understandings of these perennially important ideas.
