Humphrey believed :

Rhythms of dance were a result of the dancer’s desire to pull toward and away from equilibrium.  She referred to the end effect as “static death/dynamic death.” By this, she meant the danger of constant equilibrium or the danger of too extreme a move away from equilibrium and used this idea as the human struggle for survival.

She did much study on the force or energy as a creative element and felt that the desire to move was natural. She found that this desire was a stimulus in all organic matter to reach out from its center point. 

 Humphrey’s ideas on equilibrium also suggested that organic matter would eventually desire to return to the center, but only to be released once again. She saw this as a balancing act to ensure the “safety” of the organism
