Abstract
Astrophysicists and cosmologists seriously propose that our universe, with its three dimensions and local physical bylaws, is one of an infinite number of parallel universes. This paper discusses the relevance of these ideas for contemporary systemic family therapy, such as thinking about the therapist’s positioning in relation to the family. Ideas such as the anthropic principle suggest each meeting of a therapist and family forms a unique systemic entity or singularity with its own universe of by-laws peculiar to a location in time and space. We are like travellers between parallel family therapy universes where the therapist’s epistemology, theory or model is less important than how therapists and clients position themselves towards each other. This ecological positioning encompasses contextual, emotional, cultural, ethical and spiritual belief systems.
