This book advances an integrative approach to understanding the phenomenon of psychosocial maturation. Through a rigorous, dialectically-informed interpretation of psychoanalytic and humanistic-existential-phenomenological sources, Mufid James Hannush distils thirty essential markers of maturity. The dialectical approach is described as a process whereby lived, affect-and-value laden polar meanings are transformed, through deep insight, into complementary and integrative meta-meanings. The author demonstrates how responding to the call of maturation can be viewed as a life project that serves the ultimate purpose of living a balanced life. The book will appeal to students and scholars of human development, psychotherapy, social work, philosophy, and existential, humanistic, and phenomenological psychology.
