All things are connected.

The material universe may be understood as a gigantic open dynamically moving active system constituted of a myriad of smaller dynamic moving systems of different kinds. Atoms combine and create those open dynamic moving systems which we call molecules. Molecules combine and create different substances out of witch we and our world is made. Suns and planets are moving systems who all together account for a universe with billons of galaxies. Galaxies interact with another. But not only that which we call matter is constantly interacting.

In one or other way all the non-material energies of this universe also have these potentials.

In the bodies of animals molecules combine and create different biological cells. Cells of different kind are the building materials of biologic organs. Organs interact creating the biological master system, a living body. The human mind can be defined in the same way. That form of consciousness which we are aware of when awake can also be seen as an active dynamic moving system wich continually interacts  with the sub-conscious and unconscious systems of the mind. Feelings, thoughts and ideas can in the same way be seen as open dynamic systems of a somewhat different kind who continuously mix and interact. Not only in the human individual but also between her and the surrounding world these dynamic moving systems of different kind and dimension continuously change information with each other. Thus operates the universe, thus operates man and thus operate the communities of man.

The human individual

can mentally experience herself and the world outside. This is an inside to outside perspective, usually seen as subjective.

But she can also look at other people and the world around her objectively, judge and measure what she is seeing and thereby decide what is under-standable and what is normal.

Both perspectives are necessary.

Health

can be defined as an experience of satisfying balance in and between an individuals body and mind systems, as well as between these and the outer world.

Public health

is pursued by society in order to assure good health to a maximum number of citizens.

Individual health

requires also self-knowledge, motivation and individual engagement.
