For Moreno spontaneity was “a new response to an old situation or an adequate response to a new situation” (1953, p. 336), with creativity adding the element of inventiveness.
Moreno, Zerka T. (1987) “Psychodrama, Role Theory, and
the Concept of the Social Atom.” in Zeig, Jeffrey K., Evolution Of Psychotherapy, first Conference. Taylor and Francis. Kindle Edition.
Zerka is quoting from the definition that is on the same page in the 1978 edition, 366.
Here is another quote from “Who Shall Survive?” 1978 edition, Page 42:
Spontaneity operates in the present, now and here; it propels the individual towards an adequate response to a new situation or a new response to an old situation. It is… the least developed among the factors operating in our world; it is most frequently discouraged and restrained by cultural devices.
So is spontaneity the response, or that which propels the response?
