Book excerpt: Although they are among the most studied people on earth, the Navajo possess a complex philosophy. . . . A valuable source for those deeply interested in the structure of the Navajo universe, its mythology, and its central concept of long life and happiness. ÑMasterkey This is a stimulating book. Essentially, it criticizes previous discussions of Navajo religion and philosophy for greatly underestimating their complexity and sophistication. . . . What the author discovers in Navajo thought is that the key concepts are interrelated in a grand, moral, ethical, philosophic, and cosmic unity." ÑAmerican Anthropologist "Discredits dualists, both non-Indian and Indian, who see simplistic oppositions of Good and Evil in Navajo culture and philosophy. The concept of walking in beauty, as related to the proper growth of the corn plant, unifies the book, and Farella does some impressive cross-cultural linguistic analysis to derive practical and ceremonial applications of these central Navajo metaphors. . . . This is one of the better books on Indian religion" ÑChoice
