This paper reflects on the "unified field" as a concept at the heart of Gestalt theory and practice. The field perspective is contrasted with a dualistic outlook that separates individuals from human systems. Instead, individuals can be regarded as embodying systems, both affected by them and affecting how they are. Implications for practice, for ideas of adult development, and for dealing with political and social issues are all discussed. The paper concludes by underlining the sociopolitical priorities of the founders of the Gestalt approach.
