Although the beginnings of “psychological healing” can be traced back several thousand years (see Jackson 1999), modern experiential therapy began in 1895 with Freud and Breuer's Studies on Hysteria. Since then, several hundred forms of psychotherapy have been developed. Most of these will be consigned to the dustbin of history, but cognitive therapy is here to stay. Although the fact is rarely acknowledged, cognitive therapy is developmentally an offspring of psychoanalysis. Aaron Beck was a young psychoanalyst when he discovered that people suffered not only from memories but also from distorted, and often unconscious, beliefs.
