Episode 6 - We are a drop in the ocean, nothing and everything: Human development with Dr. Susanne Cook-Greuter

Dr. Susanne Cook-Greuter discusses her early life, family influence, academic journey, and the discovery of adult development theories. She emphasizes the empirical grounding of ego development theory and introduces the arc representation of development and stages of ego development in Western culture. Our conversation explores cultural conditioning and growth in postconventional stages. We also discuss cautions and limitations as well as the gifts and flexibility of ego development theory, challenges of categorization and hierarchy, and uncertainty of the future. The discussion concludes with encouragement for finding joy in daily life.
