The unconscious mind is thought to be a deeper part of a person's mind that works without that person knowing it. Feelings, thoughts, desires or emotions appear to come out of nowhere, leaving the person to question where they came from.
The unconscious mind is a term coined by the 18th century German romantic philosopher Friedrich Schelling and later introduced into English by the poet and essayist Samuel Taylor Coleridge.[1] It is, however, an ancient idea which has been noticed in many civilisations and cultures. Also, whether other mammals have similar mental mechanisms to man is also a question with a considerable history.[2]
