Abstract: This paper deals with different postulates and their consequences for the theoretical foundation of physical reality. If a theory is complete, it is required that ?Every element of the physical reality must have a counterpart in the physical theory? 1. However, this requirement is biased by the word element which has to be replaced by the word everything. The requirement for a complete theory will then be the following: everything in the physical reality must have a counterpart in the physical theory. An element can be understood as limited to mass or matter only. In the search for the foundation we need an open mind, so we must look in all directions; that?s why element has to be changed to everything, or the theory will not be complete.
