Mitwelt is a German term used in existential therapy to refer to an individual's social or cultural environment.
[1] Problems in the mitwelt center on integration vs. isolation, or individuality vs. conformity.
The individual is tasked with the responsibility to achieve a balance between these opposing states in order to derive existential meaning from a social group while maintaining one's autonomy.
The mitwelt (social dimension) is one of four existential dimensions.
The others include: Umwelt (physical dimension) Eigenwelt (psychological dimension), and Überwelt (spiritual dimension).
