In this classic work, Karl König attempts to explain the various characteristics of first-, second- and third-born people, without losing sight of the tremendous individuality of the human being. Just as our environment shapes our language, social behavior and mannerisms, so our place in the family also determines how we encounter life. This book is a fascinating handbook for parents, teachers and caregivers. Over the years it has become a definitive reference on the subject of child development. This newest edition in the Karl König Archive series includes a new introduction by series editor Richard Steel; an extended introduction by Karl König; two new essays: 'The Two Sisters', and 'Brother and Sister' ; some of Karl König's lecture notes and transcriptions, and an essay by A. Limbrunner about the significance of König's work on family order for today.
