According to the science of cybernetics, which deals with the topic of control in every kind of system (mechanical, electronic, biological, human, economic, and so on), there is a natural law that governs the capacity of a control system to work. It says that the control must be capable of generating as much "variety" as the situation to be controlled.

The system of transportation is not coherent; it is not treated as integral. Roads compete with with railroads and airlines in chaotic fashion, and at immense cost to the nation.

Instead of trying to specify a system in full detail, specify it only somewhat. You can then ride on the dynamics of the system in the direction you want to go.

It is terribly important to appreciate that some things remain obscure to the bitter end.

There is, then, a logical priority about the arrangements, and logic has nothing to do with time.

If cybernetics is the science of control, management is the profession of control.
