An alter ego (Latin, "the other I") is a second self, which is believed to be distinct from a person's normal or original personality. The term was coined in the early nineteenth century when dissociative identity disorder was first described by psychologists. A person who has an alter ego is said to lead a double life.
A distinct meaning of alter ego can be found in literary analysis, wherein it describes characters in different works who are psychologically similar, or a fictional character whose behavior, speech or thoughts intentionally represent those of the author. It's also used to design the best friend of another character in a story. Similarly, the term alter ego may be applied to the role or persona taken on by an actor or by other types of performers.
The existence of "another self" was first recognized in the 1730s. Anton Mesmer used hypnosis to separate the alter ego. These experiments showed a behavior pattern that was distinct from the personality of the individual when he was in the waking state compared to when he was under hypnosis. Another character had developed in the altered state of consciousness but in the same body.
Alter ego is also used to refer to the different behaviors any person may display in certain situations. Related concepts include avatar, doppelgänger, impersonator, and split personality.

Famous quotes containing the words alter and/or ego:
“No legislation can suppress nature; all life rushes to reproduction; our procreative faculties are matured early, while passion is strong, and judgment and self-restraint weak. We cannot alter this, but we can alter what is conventional. We can refuse to brand an act of nature as a crime, and to impute to vice what is due to ignorance.”
—Tennessee Claflin (1846–1923)
“Analysis does not set out to make pathological reactions impossible, but to give the patient’s ego freedom to decide one way or another.”
—Sigmund Freud (1856–1939)
