While spontaneity is more an action than an idea, it has been called the primary virtue and a one-word summary of the Beat Movement. This theme more than any other speaks to the frenzied, intense emotional states that many Beats found both exhilarating and necessary. Moreover, it embodies the tendency not to think twice about hopping into a car and taking off for unknown destinations just for the thrill of adventure and the prospect of discovering something new about oneself and life in general. To be impulsive was not to be cautious. For the Beats, caution was a symptom of social conformity, and living off the cuff was an openly defiant response to such careful, regimented existence.
