What is the author's tone in Goddesses in Everywoman: A New Psychology of Women by Jean Shinoda Bolen?

The tone of the book is serious. It is objective, but the author is careful to not be excessively so. The reason for this is partly the gender bias but also due to the nature of the subject matter. Psychology and the goddesses are interpersonal in their focus. As such, 'impersonal objectivity' would undermine the intention.
