This volume contains a representative selection of talks and writings by Martha Harris and Donald Meltzer on the key developmental phase of adolescence, from their teachings both separately and together over many years. Their psychological penetration into this phase or condition transcends changes in culture and environment, focussing on the ‘community of adolescents’ as a state of mind struggling with confusion manifest not only in sexuality but in all aspects of life. This collection includes in many cases the post-talk discussions of the original seminars and is equally relevant to both parents and therapists.
