Physis

Eric Berne (founder of Transactional Analysis) noted four forces which act on the little person: the encouraging and the limiting influences from parents and parent figures, Fate, and ‘physis’.

Physis is the urge to life and growth, which enables us to overcome adversity and say “This is what I want to do, and I’d rather do it my own way”  (Berne, 1972).

This positive force derives from the energy of the Child egostate, the source of spontaneity, creativity and joy. This liberating concept sees creativity and self-fulfilment as normal processes.
