a conclusion, decision or resolution made by the individual himself to resolve a problem or to set a pattern for the future or to nullify a pattern of the past. For example, a person says, "I like Model T Fords. I am never going to drive another car." Years later, no longer consciously aware of this postulate, he will wonder why he is having so much trouble with his Buick; it's because he has made an earlier promise to himself. In order to change he has to change that postulate.
