In the past, the use of metaphor was wrong and deviant while others saw metaphor as insight. To others metaphor allows the unknown to be known. Today people believe metaphor to be unusual and intrigues people in life. Metaphors stretch in many forms and can appear in our conversations, news, and idioms. Metaphors are also believed to add to people's understanding of the world and allow people to map concepts. For example, journeys are often correlated with life, love, time, emotion, or food. Metaphors are not limited to language but are universal because it also has to do with our minds and body.
