Self-organizing takes place in the process of emergence. Selforganization properly takes place with living forms, for they have a self capable of organizing. But the term often loosely indicates a mechanical transition in the organization of matter and energy taking place in a phase change determined by external causes. Selforganization often refers to the over-all outcome of an emergent process—the self-organization of a flock in flight. Phase change often refers to the specific transformations undergone as some emergent state self-organizes. Thus, an emergent whole self-organizes as its components each go through a change of phase.
