The functionalist principles allow managing the roots of the functionality of things and the root causes of problems. The functionalist principles are based on the functionalist approach to science. Functionalist principles are not a matter of opinion. They are a matter of evidence.
The functionalist principle defines that there is nothing in the universe, which is part of a system, that does not work with a purpose, an active and entropic function, and an energy conservation function. Their interaction defines the functionality of the binary actions that make functionalist principles work.
Binary actions are two synchronized actions that, one the one hand, open possibilities establishing a functional context and, on the other hand, close processes to generate results.
