The soul, in some religions, spiritual traditions, and philosophies, is the incorporeal or eternal part of a living being, commonly held to be separate from the body. Many philosophical and religious systems teach that humans have souls; some attribute souls to all living things and even inanimate objects (such as rivers); this belief is commonly called animism. The soul is often believed to exit the body and live on after a person’s death, and some religions posit that God creates souls.

The soul has often been deemed integral or essential to consciousness and personality, and may be synonymous with spirit, mind or self. Although the terms soul and spirit are sometimes used interchangeably, soul may denote a more worldly and less transcendent aspect of a person. According to psychologist James Hillman, soul has an affinity for negative thoughts and images, whereas spirit seeks to rise above the entanglements of life and death. The words soul and psyche can also be treated synonymously, although psyche has more physical connotations, whereas soul is connected more closely to spirituality and religion.

Character
( as seen in the field of the arts )

A character is the representation of a person in a narrative or dramatic work of art (such as a novel, play, or film). Derived from the ancient Greek word kharaktêr (χαρακτήρ), the earliest use in English, in this sense, dates from the Restoration, although it became widely used after its appearance in Tom Jones in 1749. From this, the sense of "a part played by an actor" developed. Character, particularly when enacted by an actor in the theatre or cinema, involves "the illusion of being a human person." Since the end of the 18th century, the phrase "in character" has been used to describe an effective impersonation by an actor. Since the 19th century, the art of creating characters, as practiced by actors or writers, has been called characterization.

A character who stands as a representative of a particular class or group of people is known as a type. Types include both stock characters and those that are more fully individualized. The characters in Henrik Ibsen’s Hedda Gabler (1891) and August Strindberg’s Miss Julie (1888), for example, are representative of specific positions in the social relations of class and gender, such that the conflicts between the characters reveal ideological conflicts.

The study of a character requires an analysis of its relations with all of the other characters in the work. The individual status of a character is defined through the network of oppositions (proairetic, pragmatic, linguistic, proxemic ) that it forms with the other characters. The relation between characters and the action of the story shifts historically, often miming shifts in society and its ideas about human individuality, self-determination, and the social order.
