Extremely well-written book in that it is easily understood by the lay person, yet gracefully expresses complex ideas and processes, and is such a complete overview of attachment theory as to be of as much use to the professional as the lay person.
Attachment theory addresses child development in terms of whether or not there is a loving attachment to a parental figure. Through following the history of the development of attachment theory the author explains the theory, the evidence supporting it, and the effects upon the individual.
While supportive of attachment theory, Karen is careful to explain the views of its critics, and to show how those criticisms often improved the theory.
I am not a psychologist, but someone with Borderline Personality Disorder trying to make sense of my life in order to improve it. Karen's work helped me enormously. His scientific orientation to provide good theory grounded in reseach and evidence is fused with his warm humanity and concern for individuals and society.
Therefore I recommend the book to professional psychologists, teachers, makers of public policy, and others who deal with children. But also I recommend it highly to those on the quest for self-understanding.
