Existential thinkers seek to avoid restrictive models that categorize or label people. Instead, they look for the universals that can be observed cross-culturally. There is no existential personality theory which divides humanity into types or reduces people to part components. Instead, there is a description of the different levels of experience and existence with which people are inevitably confronted. The way in which a person is in the world at a particular stage can be charted on this general map of human existence (Binswanger, 1963; Yalom, 1980; van Deurzen, 1984).
