Dr. Sidney J. Blatt, who received a Ph.D. in personality development and psychopathology from the University of Chicago in 1957, is considered one of the most thorough and experienced authorities in modern psychology. In this book, Dr. Blatt examines the contrasting theories of relatedness and self-definition, and how the human mind wrestles with these polarized concepts throughout life. Dr. Blatt's theories are considered particularly groundbreaking and controversial since many of his ideas can be directly applied to psychotherapy, replacing current DSM guidelines regarding mental disorders and their related symptoms.
