Holon A Holon is a part of the universe which is complete and consistent in itself, but is also an necessary integral part of a greater system which encompasses it. E.g. Atoms are a holon. Atoms are complete in themselves. They have a consistent form that can be relied to be the same no matter where they are found.
Atoms however can join together to form molecules.
Molecules are made of atoms. Molecules encompass atoms. Molecules are more complex than atoms. Molecules are holons because they are complete and consistent within themselves and because they can be organised into a basic living cell. Cells are holons which can form a body organ.
