Depth psychologist and wilderness guide Bill Plotkin offers us a model for a human life span rooted in the cycles and qualities of the natural world, a blueprint for individual and collective development. Defining eight stages of human life — Innocent, Explorer, Thespian, Wanderer, Soul Apprentice, Artisan, Master, and Sage, Plotkin offers a primer on human development and a manifesto for change. In this book he also fashions a template for a more mature, fulfilling, and purposeful life — and a better world.
