The inquisitive mind of a journalist and the inquisitiveness of Frank Herbert gave the world a surprisingly thoughtful and multi-layered novel, which received the title of classic science fiction literature. The writer's string of diverse interests - Jungian psychology, graphology, diving, aviation and ecology - contributed to the incredibly complex and bizarre world of Dune. And the problems that worried Herbert half a century ago turned out to be more relevant than ever in the modern world. Understanding the depth of the novel will require fundamental knowledge of more sciences: ecology, philosophy, history, ethics, religion, and linguistics. This book will help to understand the philosophical aspects of the Dune Universe and will allow you to understand the ideas that the author put into it.
