There may be loss of information, addition of information, or distortion of information. In this way, patterns mutate. Order and chaos are aspects of the Pattern. This results from the limitations of mind. This results from complexity.
Orderly change follows the normal patterns of growth, maintenance and decay.
Chaotic change follows a multitude of patterns. Systems of control and limitation may cause chaotic patterns to become ordered. Imposition of order may cause increaed chaos. Appropriacy is determined by nature, timing and degree. Patterns have intrinsic tendencies.
