APA Dictionary of Psychology

in existential psychology, a person’s worldview or fundamental orientation toward life: their essential mode of being-in-the-world. The term and concept come from the work of Swiss existential psychologist Ludwig Binswanger (1881–1966). A person’s world design includes the way in which that person integrates the totality of their personality with the world as they experience it. In this approach, understanding a person’s world design is essential in understanding the person.
