Nathaniel Branden’s Legacy to the Science of Clinical Psychology

This article presents a summary of the key aspects of the Biocentric theory of psychology proposed and developed by Nathaniel Branden. The themes of the conscious and nonconscious aspects of the mind and their interplay in healthy and psychopathological human functioning are highlighted, with the development and maintenance of self-esteem as the centerpiece of this schema. Branden’s cogent, in-depth analysis and synthesis of these issues, presented for the first time over fifty years ago, is discussed in relation to issues that are being actively researched today.
