A holon is a node in the tree structure. Holon comes from the Greek holos meaning "whole" and on meaning "part" or particle. The key characteristics of a holon include that it asserts its individuality in order to maintain the set order in the tree structure, but it also submits to the demands of the whole tree structure (the system) in order to make the system viable. Holons are self-contained, autonomous pieces which follow a prescribed set of rules. The holon has a "self-assertiveness tendency" (wholeness) as well as an "integrative tendency" (part).This duality is similar to the particle/wave duality of light.(Koestler, 1967)
