Gnosticism which is based on a strict dualism between light and darkness accepts a trikotonomy concerning the human being. Thus human is accepted as a being that consists of three different factors, namely body, spirit and soul, or hylic, pneuma and psyche. According to Gnostic anthropology body and soul have completely negative characteristics since they belong to the material world. Contrary to this, spirit belongs to the heavenly world and, therefore, has such positive characteristics as life and light. Body and soul, the psychic element in the body, are described as a prison for spirit that is a fallen light being in this material world and body. It is necessary for spirit to oppose the body and soul in order to set free himself from this prison. [ABSTRACT FROM AUTHOR]
