Never ceasing to stimulate controversy, Freud is acknowledged as the founder of psychoanalysis, the key to unlocking the human mind, which has become so essential to mankind's survival in all the confusions of the 20th century. As science and technology have often rushed ahead of our ability to cope with the consequences, Freud saw that man is at war with himself and often unable to tolerate too much reality, and he pronounced that dreams are the contraband representations of the beast within man which are smuggled into awareness during sleep. In Freudian interpretation, the analysis of dreams constitutes the key to unlocking the vital secrets of the unconscious mind.
