Book excerpt: This book demonstrates how Merleau-Ponty's understanding of the continuity of inner and psychological life (interiority) and the material world (exteriority) has broad implications for philosophy, the physical and human sciences, and health studies. By taking the phenomenon of the body out of the dualistic constraints of interior and exterior, idealism and empiricism, Merleau-Ponty shows us the possibility of a fresh vantage point for future research and therapeutic application, linking philosophy more closely to the study of nature, the psyche, and social phenomena. Merleau-Ponty, Interiority and Exteriority, Psychic Life and the World is proof of the power and creative energy of Merleau-Ponty's thought. Contributors include Edward S. Casey; Helen A.
