In the days of the original iPhone, there was a simple choice to be made when buying a new smartphone - would you buy an iPhone or would you buy a model made by the competition, say an HTC or a Samsung device?
Despite the widely-recognized failure of Freudian psychotherapy to heal disturbed people effectively and the rejection of many of his major theories Freud remains one of the most influential figures of the 20th century.
Freud's basic insight that our minds preserve memories and emotions which are not always consciously available to us has transformed the way humanity views itself ever since. Freud said that there had been three great humiliations in human history:
Galileo's discovery that we were not the center of the universe
Darwin's discovery that we were not the crown of creation,
and Freud's own discovery that we are not in control of our own minds.
The tendency of modern people to trace their problems to childhood traumas or other repressed emotions begins with Freud. One of Freud's more important discoveries is that emotions buried in the unconscious surface in disguised form during dreaming, and that the remembered fragments of dreams can help uncover the buried feelings.
Whether the mechanism is exactly as Freud describes it, many people have derived insights into themselves from studying their dreams, and most modern people consider dreams emotionally significant, unlike our ancestors who often saw them either as divine portents or as the bizarre side-effects of indigestion.
Freud argues that dreams are wish-fulfillments, and will ultimately argue that those wishes are the result of repressed or frustrated sexual desires. The anxiety surrounding these desires turns some dreams into nightmares.
