This chapter provides general introduction to Moreno’s ideas, designed for the newcomer to the field. The objective of psychodrama was, from its inception, to construct a therapeutic setting which uses life as a model, to integrate into it all the modalities of living, beginning with the universals time, space, reality, and cosmos down to all the details and nuances of life. Man lives in time past, present, and future. He may suffer from a pathology rekted to each. The problem is how to integrate all three dimensions into significant therapeutic operations. It is not sufficient that they figure as “abstract” references; they must be made alive within treatment modalities. The psychological aspect of time must reappear in toto. Freud, an exponent of genetic psychology and psychobiology, found going back and trying to find the causes of things of particular interest.
