There are two interesting ideas in Freud’s theory: first, the existence of
unconscious motivation; second, the concept of unconscious conflict. Freud believes that unconscious motivation might play an important role in a lot of situations, such as marriage, forgetting a person’s name, calling out the wrong name etc. In his view, there are three processes going on in the head, namely, id, ego and superego, which are in violent internal conflict. Id functions on“the Pleasure Principle”, while ego works on “the Reality Principle”and superego is the internalized rules of a society. Ego is in between id and superego.
