Key Definitions The theory is based on the following essential definitions. Logic is defined as a correct reasoning that forms the basis of any science. Living System is a unit comprised of elements that work in a coordinated manner, each in service to the other, to achieve the common goal of survival. This definition applies to bacteria, viruses, ant colonies, persons, groups, institutions or countries. Intelligence (I) is the regulating entity that controls and integrates parts of a living system, in a functional unit, directed and geared towards survival. Energy (E) is any fuel that causes action or movement, also defined as that which makes things occur. Organization (O) is a group of elements ordered as a functional unit, directed towards goals established by the intelligence that rules them. In a living system, the functions performed by I, E and O are similar to those functions carried out in a moving vehicle, by driver, fuel and the vehicle itself.
