In psychology, the psyche /ˈsaɪki/ is the totality of the human mind, conscious and unconscious.[1]
Psychology is the scientific or objective study of the psyche. The word has a long history of use in psychology and philosophy, dating back to ancient times, and represents one of the fundamental concepts for understanding human nature from a scientific point of view. The English word soul is sometimes used synonymously, especially in older texts.[2]
