there are three laws existing in nature that rule the world
gravity
electro-magnetism
and , as soon as there is any kind of life existent: The Motivation
and they´re classified in this succesion.
gravity is the basic law: Masses adducting each other
electro-magnetism can bear down gravity
and finally, the motivation of lifeforms can bring out actions which arent explainable with gravity or electro-magnetism. Well, they can explain how lifeforms act, contraction of muscels by electric stimulation and so on. But they can´t caxplain why a lifeform acts at all.
I think, we´re standing in all three sciences still at the beginning of the understanding.
